Deadline/ N/A Timeline: Background: • The City Council budgeted $20,000.00 from the Capital Improvement Fund for the construction of a salt storage building in 2008. This project was recommended by the Capital Improvement committee in 2007. The shelter would allow the City to have supplies on hand when needed, make fewer trips to the County Storage shed during snow events and protect the mix from the elements. • Approximately in 2001, a 42' wide by 30' deep slab with 3'10" high 8"thick walls was poured for the storage of salt on site. • Three types of structures were considered: 1. Steel building -due to the corrosive reaction of the salt on steel, this option was not explored deeply; 2. Wood building -the structure is required to have fairly tall walls, about 20'. The engineering, required by the Building Code, makes a wood building very expensive (over $50,000); 3. Fabric structure (Cover-All) -this is the most common building used for the storage of salt. The steel truss system is clad with a corrosive resistant exterior and the building is rated for Minnesota wind and snow loads. It is economical and offers the most efficient use of the space as well as ease of use. The building would completely enclose the salt pile and would have an entrance on the south end that would allow for the front end loader or dumpers to enter. • Two quotes were received (a third could not fit the existing walls). Both quotes include a 42' wide by 30' deep building and installation: 1. Cover All/Greystone Construction submitted a bid for Page 1 05/01/08 $14,487.39; 2. Tek Supply submitted a bid for $15,315.67. • Staff contacted several references. The Coon Rapids Street Superintendent has been very pleased with the service he has received from Greystone in the last 6 years their building has been up as well as the Cover-All structure. Forest Lake has a Cover-All salt shed and is very pleased with the performance (they installed it themselves.) Amador Clydesdales has a Cover-All building and show it on their website (John Morrison visited the site.) • We are still waiting on a quote for the covering of the 16'wide x 16' high opening. John would like the roll up fabric with a chain hoist. The City of Scandia would be required to install 2 tube footings at the sides of the opening for support ($200) and hire an electrician to get power out to the building for the door opener(about $1500). [The building, to meet the Electrical Code, would need an interior and exterior light, an outlet but much of the cost stems from the wire coming from the far end of the building where the electrical panels are located and trenching.] Recommendatio My recommendation as well as John Morrison's would be to go n: with a Cover-All building installed by Greystone Construction. They are a local company out of Shakopee and have done considerable work in this area(RiverBank in Wyoming, Stacy Municipal Bar and others). Greystone has constructed approximately 80 of these structures in the State of Minnesota. Cover-All has a very good reputation as does Greystone Construction. The final cost, including covering the end/door should be within the $20,000 budgeted. If not, staff would come back to the Council for approval of any additional expense.

No.: 14059.002 From: Richard E. Thompson, AICP Scandia File Number 2008008 Date: April 30, 2008 SUBJECT: 21300 Olinda Trail North Rezoning from "General Business"to "Single Family Estate" MEETING DATE: May 6, 2008 LOCATION: 21300 Olinda Trail North Scandia, Minnesota APPLICANT: David and Wynness Holmberg 60-DAY PERIOD: June 20, 2008 ZONING: General Business ITEMS REVIEWED: 1. Memo to Shen-i Buss from Steve Thorp dated April 15, 2008. 2. Application for Planning and Zoning Request Scandia File No. 2008008. 3. Sketch of Lots 1, 2, 3, and parts of Lots 9 and 10 showing existing garage and future addition. BRIEF DESCRIPTION OF THE REQUEST: The Applicants are proposing to rezone their homestead property from "General Business"to "Single Family Estate". Their property, which consists of three full city lots and parts of two others, formerly included a commercial greenhouse, which has been removed. With removal of the greenhouse, there is no longer any commercial use of the property. After rezoning of the property, the Applicants wish to remove their existing detached garage, and construct a new garage and connecting an addition in-line with the house. EVALUATION OF THE REQUEST: The Applicants wish to tear down their existing garage and rebuild a new garage and attach it to their house. Their property is currently zoned "General Business", which has no primary or permitted uses. Single family residences are not listed as either uses permitted with a Certificate of Compliance or a Conditional Use Permit. Therefore, a single family residence in the General Business District is a non-conforming use. A non- An Employee Owned Company Promoting Affirmative Action and Equal Opportunity 21300 Olinda Trail North Rezoning Page 2 April 30, 2008 . Scandia, Minnesota conforming use cannot normally be expanded. For this reason, the Holmberg's have requested to rezone their property. The zoning ordinance states that "the purpose of the General Business District is to provide an area for a general mix of commercial and industrial businesses that are non-threatening to the environment." It appears the land was zoned "General Business"because there was a commercial greenhouse on the property,because the property is contiguous to other properties zoned "General Business" on the east and south, and because the Comprehensive Plan includes this area in the Village Center. The Village Center designation allows both commercial and residential uses. The first question addresses the current use. There is currently no commercial use for this property and no commercial use is planned. The Applicants are proposing to strengthen the residential use of their property. The second question addresses the issue of spot zoning. This property is on the northwest edge of the "General Business District". On the north and west sides, the land is zoned "Single Family Estate". Thus there is no issue of spot zoning, and rezoning would be compatible with the properties to the north and west. The third question relates to the Comprehensive Plan, and the intent of the Village Center designation. The Village Center designation is clearly intended to provide for both residential and commercial uses. The Comprehensive Plan states: "The current delineation of the rural center incorporates approximately 60 homes and 20 businesses..."The Plan further states that residential development is an integral part of the Village Center. The Plan also states that "Future commercial development should be oriented towards the traditional village center", which although not defined, could be the area directly north of Highway 97 and primarily the area south of Highway 97. From the information provided in the Comprehensive Plan, it would be consistent to rezone this property to Single Family Estate, since the Village Center designation allows this zoning district, and since the Plan states that future commercial development should be focused to the traditional Village Center. For the reasons stated above, the Planner recommends that the City rezone the Holmberg property from "General Business" to "Single Family Estate"based on the following findings: 1. The only current use of this property is residential, and there are no existing or planned commercial uses. 2. The property is adjacent to lands zoned "Single Family Estate"on the north and west, so the rezoning would be consistent with these adjacent properties, and there would be no question of spot zoning. 3. The Comprehensive Plan designation of Village Center allows both residential and commercial uses. The Plan states: "...the concept underlying the village center plan is to offer an alternative to large lot, [residential] rural sprawl..."The Plan not only allows residential development, but it expressly supports it. 4. The Comprehensive Plan favors future commercial development that is oriented to the traditional Village Center. This property, although on the edge of the traditional Village Center, it is not an area that the Plan promotes for future commercial expansion. Since the Village Center designation of the Comprehensive Plan allows both residential and commercial uses, there is no need for a plan amendment. 21300 Olinda Trail North Rezoning Page 3 April 30, 2008 " Scandia, Minnesota The existing home is a nonconforming structure in that it does not meet setback requirements. The Development Code, Chapter 1, Section 12.3 (1) (A) addresses the conditions under which a nonconforming structure may be expanded without a variance. A variance is not needed to build the proposed garage/addition attached to the existing home because: 1. the garage/addition does not violate the provisions of the Development Code, other than the setback requirements that make the house nonconforming in the first place; and 2. long-term sewage disposal needs can be met. PLANNING STAFF RECOMMENDATIONS: The Planner recommends that the Holmberg property at 21300 Olinda Trail be rezoned from "General Business"to "Single Family Estate", based upon the findings above. i File No. ) 00 e 0 0 APPLICATION FOR PLANNING AND ZONING REQUEST City of Scandia, Minnesota 14727 209th Street North, PO Box 128, Scandia, MN 55073 Phone 651/433-2274 Fax 651/433-5112 Web http://www.ci.scandia.mn.us Please read before completing: The City will not begin processing an application that is incomplete.

No.: 14059.002 From: Richard E. Thompson, AICP Scandia File Number 2008008 Date: April 30, 2008 SUBJECT: 21300 Olinda Trail North Rezoning from "General Business"to "Single Family Estate" MEETING DATE: May 6, 2008 LOCATION: 21300 Olinda Trail North Scandia, Minnesota APPLICANT: David and Wynness Holmberg 60-DAY PERIOD: June 20, 2008 ZONING: General Business ITEMS REVIEWED: 1. Memo to Sherri Buss from Steve Thorp dated April 15, 2008. 2. Application for Planning and Zoning Request Scandia File No. 2008008. 3. Sketch of Lots 1, 2, 3, and parts of Lots 9 and 10 showing existing garage and future addition. BRIEF DESCRIPTION OF THE REQUEST: The Applicants are proposing to rezone their homestead property from "General Business"to "Single Family Estate". Their property, which consists of three full city lots and parts of two others, formerly included a commercial greenhouse, which has been removed. With removal of the greenhouse, there is no longer any commercial use of the property. After rezoning of the property, the Applicants wish to remove their existing detached garage, and construct a new garage and connecting an addition in-line with the house. EVALUATION OF THE REQUEST: The Applicants wish to tear down their existing garage and rebuild a new garage and attach it to their house. Their property is currently zoned "General Business", which has no primary or permitted uses. Single family residences are not listed as either uses permitted with a Certificate of Compliance or a Conditional Use Permit. Therefore, a single family residence in the General Business District is a non-conforming use. A non- An Employee Owned Company Promoting Affirmative Action and Equal Opportunity 21300 Olinda Trail North Rezoning Page 2 April 30, 2008 Scandia, Minnesota conforming use cannot normally be expanded. For this reason, the Holmberg's have requested to rezone their property. The zoning ordinance states that"the purpose of the General Business District is to provide an area for a general mix of commercial and industrial businesses that are non-threatening to the environment." It appears the land was zoned "General Business"because there was a commercial greenhouse on the property, because the property is contiguous to other properties zoned "General Business" on the east and south, and because the Comprehensive Plan includes this area in the Village Center. The Village Center designation allows both commercial and residential uses. The first question addresses the current use. There is currently no commercial use for this property and no commercial use is planned. The Applicants are proposing to strengthen the residential use of their property. The second question addresses the issue of spot zoning. This property is on the northwest edge of the "General Business District". On the north and west sides, the land is zoned "Single Family Estate". Thus there is no issue of spot zoning, and rezoning would be compatible with the properties to the north and west. The third question relates to the Comprehensive Plan, and the intent of the Village Center designation. The Village Center designation is clearly intended to provide for both residential and commercial uses. The Comprehensive Plan states: "The current delineation of the rural center incorporates approximately 60 homes and 20 businesses..."The Plan further states that residential development is an integral part of the Village Center. The Plan also states that"Future commercial development should be oriented towards the traditional village center", which although not defined, could be the area directly north of Highway 97 and primarily the area south of Highway 97. From the information provided in the Comprehensive Plan, it would be consistent to rezone this property to Single Family Estate, since the Village Center designation allows this zoning district, and since the Plan states that future commercial development should be focused to the traditional Village Center. For the reasons stated above, the Planner recommends that the City rezone the Holmberg property from "General Business" to "Single Family Estate"based on the following findings: 1. The only current use of this property is residential, and there are no existing or planned commercial uses. 2. The property is adjacent to lands zoned "Single Family Estate"on the north and west, so the rezoning would be consistent with these adjacent properties, and there would be no question of spot zoning. 3. The Comprehensive Plan designation of Village Center allows both residential and commercial uses. The Plan states: "...the concept underlying the village center plan is to offer an alternative to large lot, [residential] rural sprawl..."The Plan not only allows residential development,but it expressly supports it. 4. The Comprehensive Plan favors future commercial development that is oriented to the traditional Village Center. This property, although on the edge of the traditional Village Center, it is not an area that the Plan promotes for future commercial expansion. Since the Village Center designation of the Comprehensive Plan allows both residential and commercial uses, there is no need for a plan amendment. 21300,Olinda Trail North Rezoning Page 3 April 30, 2008 Scandia, Minnesota The existing home is a nonconforming structure in that it does not meet setback requirements. The Development Code, Chapter 1, Section 12.3 (1) (A) addresses the conditions under which a nonconforming structure may be expanded without a variance. A variance is not needed to build the proposed garage/addition attached to the existing home because: I. the garage/addition does not violate the provisions of the Development Code, other than the setback requirements that make the house nonconforming in the first place; and 2. long-term sewage disposal needs can be met. PLANNING STAFF RECOMMENDATIONS: The Planner recommends that the Holmberg property at 21300 Olinda Trail be rezoned from "General Business"to "Single Family Estate", based upon the findings above. i File No. ) 00 0 0 APPLICATION FOR PLANNING AND ZONING REQUEST City of Scandia, Minnesota 14727 209th Street North, PO Box 128, Scandia, MN 55073 Phone 651/433-2274 Fax 651/433-5112 Web http://www.ci.scandia.nm.us Please read before completing: The City will not begin processing an application that is incomplete.

MEMORANDUM To: City Council Reference: Bracht Bros., Inc - Conditional Use Planning Commission Permit Application for a Mining and Anne Hurlburt, Administrator Processing Operation Copies To: Proj. No.: 13812.009 From: Sherri Buss, R.L.A. Routing: Date: May 2, 2008 SUBJECT: Bracht Bros., Inc. - Conditional Use Permit Application for a Mining and Processing Operation MEETING DATE: May 6, 2008 LOCATION: All that part of the south half of the Northwest Quarter of Section 35, Township 32, Range 20, Washington County, Minnesota APPLICANT: Bracht Bros., Inc. 8303 216th Street North Forest Lake, MN 55025 120-DAY PERIOD: June 12, 2008 ZONING: Agricultural District ITEMS REVIEWED: Application, Plans BRIEF DESCRIPTION OF THE REQUEST: The Application is for a new Conditional Use Permit (CUP) for an existing sand and gravel mining operation located on 185th St. North in Scandia. Mining at the site predates any type of permitting. The site has been issued five-year pen-nits by Washington County since 1991, when the County exercised land use authority within New Scandia Township. The Applicant proposes no change in the extent of mining and operations from those approved in the previous County permit. Site Operations The site is 40 acres in size. The mining permit is requested for approximately 25 of these acres. The mining operations include extraction of sand and gravel with loaders. The material is crushed on-site using a portable crusher that is periodically brought to the site when needed. A wash plant, including conveyors, :reens and a supply well, is also located on the site, in the lower portion of the mine floor. Washing with Water removes the fine particles associated with the sand and gravel. The water source is a well on the site, An Employee Owned Company Promoting Affirmative Action and Equal Opportunity Scandia Planning Commission Page 2 May 2, 2008 Bracht Bros, Inc., CUP for Mining and the Applicant obtains a Minnesota DNR Water Appropriations Permit annually for the well. After use in the wash plant, the water is discharged to sedimentation basins. After settling, the water is recycled back to the wash plant. The applicant indicates that recycled water is used for approximately 80 percent of the wash plant operation. The sedimentation basins are dredged periodically, and the dredged material is used in site reclamation. The site produces approximately 15,000 cubic yards of sand and gravel per year. The application indicates that the lowest mining elevation will be 920 ft. above sea level, and that this is 10 feet or more above the ground water elevation on the site. The existing drainage pattern retains the surface water run-off on the site. Storm water runoff collects in the sedimentation ponds and at the lower portions of the mine floor. The Applicant indicates that the same drainage pattern would be retained after reclamation, with all runoff remaining within the site. The site has some existing berms and vegetation areas around the mining operations area. No additional screening is proposed. Mining has been conducted in three phases, approximately the north 1/3, the south 1/3 and the central 1/3 of the site, in that order. Mining is complete in the phase 1 area, and some of area has been reclaimed. A portion of the phase 1 area is occupied by a sedimentation pond. The Applicant estimates that mining will continue in the phase 2 area for an additional 1 to 3 years. Half of the phase 2 area has been backfilled. When mining is complete in the phase 2 area, mining activities will move to the phase 3 area. The eastern part of the phase 2 area will be backfilled as mining begins in the phase 3 area. Processing operations will remain in the center of the site in phase 3. The Applicant estimates that 10-15 years of mining activity remain at the site, depending on market demand. The Applicant notes that there is no blasting at this site. Reclamation Plan The proposed reclamation plan includes backfilling to create slopes up to a maximum 4:1 gradient, adding topsoil, seeding, and mulching. The reclamation will leave a deep bowl in the mined portions of the site, visible in the cross-sections provided by the Applicant. EVALUATION OF THE REQUEST The Applicant is requesting a Conditional Use Permit for a mining operation. The use is governed by the City's Ordinance No. 103, Mining and Related Activities Regulations. This review evaluates the request for a CUP based on the City's Ordinance and the materials submitted by the Applicant. Groundwater-Related Issues Leggette, Brashears and Graham, Inc. (LBG) conducted an initial review of CUP Application and related information in March 2008. From this review process, LBG identified specific portions of the CUP Application that required additional information and/or clarification on ground-water related issues. LBG Scandia Planning Commission Page 3 May 2, 2008 Bracht Bros, Inc., CUP for Mining -- prepared a series of questions that outlined these data gaps, which were submitted to Sunde Engineering through TKDA. Sunde responded in writing on April 15, 2008. LBG has reviewed this recent information and found that it sufficiently addressed the questions with the exception of the items identified in the LBG letter dated 4/28/08. Sunde will be required to provide the items identified in order for the City to issue a Conditional Use Permit for the Bracht Mining Operation. Key Groundwater-Related Issues: 1) Ground-Water Elevations and Flow Direction: Observation wells have not been installed in the water table aquifer at the site. As a result, depth to the water table surface and the direction of ground-water flow in this aquifer was estimated by Sunde from on-site soil boring logs and information provided in the Washington County Geologic Atlas (Atlas) (Figure 2). Depth to ground- water and grade elevations noted on the boring logs from 1989 indicates the ground-water elevation decreases from 915 feet above mean sea level (amsl) on the west side of the site to 905 feet amsl on the east side. Although the borings were drilled in a line which is not ideal for determining ground- water flow direction, the general west to east flow direction agrees with the data provided in the Atlas. LBG concurs with the information presented in the CUP Application that the horizontal flow component of the water table aquifer is generally from west to east across the site. Ground-water levels in a shallow, water table aquifer can vary significantly over time because of changes in precipitation and recharge. Frequent monitoring of water levels and comparison to precipitation records should be required as part of the Annual Operating Permit to establish seasonal variations and long-term trends. 2) Hydraulic Connection- Sand and Gravel and Bedrock Aquifers: Determining the hydraulic connection between different aquifers requires review of quality geologic logs, and collection and evaluation of ground-water level data. The boring logs from the site show the geology consists of three units. From top to bottom these include: 1) a sand and gravel unit; 2) a clay layer; and, 3) bedrock of the Prairie du Chien Group and Jordan Sandstone formations. The sand and gravel is the unit being mined and includes the water table aquifer. Based on current information, the water table surface is below the elevation of the existing and proposed mine floor. Geologic logs from soil borings 2 and 3 show the clay is approximately 18 feet thick and may act as a confining unit that hydraulically separates the sand and gravel aquifer from the underling Prairie du Chien-Jordan aquifer. The production well pumps from the Prairie du Chien-Jordan. Historical ground-water level data from the sand and gravel aquifer and the underlying Prairie du Chien-Jordan aquifer are currently unavailable to accurately evaluate the hydraulic connection between these water-bearing units on site. Ground-water elevations estimated from the borings in 1989 ranged from approximately 905 to 915 amsl. (Note: Since observation wells were not constructed in these borings, these water-level results represent a one-time measurement that cannot be repeated or confirmed.) The hydraulic head in the Prairie du Chien-Jordan below the site was not available until 1992 when the production well was installed. At that time depth to water was 26 feet below grade, but no survey results were available to establish a ground-water elevation. A subsequent survey completed by Landmark Surveying, Inc. (date unknown, but data was included in Sunde's April 15, 2008, response in Attachment 1) reported a grade elevation at the production well Scandia Planning Commission Page 4 May., 2008 Bracht Bros, Inc., CUP for Mining of approximately 939 feet amsl, which puts the ground-water elevation at approximately 913 feet amsl. This is similar to the water-table elevation estimated from the on-site borings. As stated in the CUP Application, the Atlas shows the hydraulic head of the Prairie du Chien-Jordan aquifer at approximately 880 to 890 feet amsl, which is approximately 25 feet below the estimated head in the sand and gravel aquifer. These results suggest the two aquifers may not be connected (Figure 2). Considering the lack of historical water elevation data from the sand and gravel aquifer, and conflicting results shown by the Atlas and site-specific data, it cannot be determined at this time if the two aquifers are connected. If the production well is to be used for monitoring water table conditions, this condition must be addressed. The production well is completed in the Prairie du Chien-Jordan aquifer, which may not be hydraulically connected to the sand and gravel aquifer that underlies the site. In addition, the portion of the production well (59 to 75 feet below grade) that is open to the bedrock aquifer is below water table surface. Monitoring below the water table may not provide accurate information. Ground water will be increasingly vulnerable as the depth of the excavation increases. In addition, if at any location in the mine the clay unit is absent, then the Prairie du Chien-Jordan aquifer will also become increasingly vulnerable. This is simply due to the vertical proximity of the mine base and the water-table or Prairie du Chien aquifer systems. 3) Additional Monitoring Needs: The CUP Application states that a diesel range organics (DRO) test monitors for contamination from diesel fuel and other petroleum based products. Although this is correct, DRO does not identify the full gasoline range organics (GRO) spectrum. If gasoline is to be used on site, then GRO, and potentially benzene, should be added to the list of analytical methods. Groundwater-Related Recommendations Given the general comments above and from LBG's review of the CUP Application and subsequent information provided by Sunde on behalf of the Applicant, LBG recommends the following conditions be include in the CUP for this site: 1) LBG recommends that the production well not be used to meet the monitoring well requirements outlined in the CUP Application. LBG recommends that Bracht install a monitoring well that is adjacent to the production well and screened in the upper part of sand and gravel aquifer, approximately 10 feet below the top of the water table. The purpose of this well is to measure the depth to water in this uppermost water-bearing unit. Comparing water-level data from this well with the production well will also help determine the hydraulic connection between this aquifer and underlying the Prairie du Chien-Jordan aquifer. 2) LBG recommends that Bracht document when the wash plant operates to better identify when the production well is pumping. This information is necessary when evaluating water level data. Scandia Planning Commission Page 5 May 2, 2008 Bracht Bros, Inc., CUP for Mining -- 3) In addition to the shallow observation well proposed near the production well, the CUP Application requires not less than one downgradient monitoring well be installed (Section II P). Therefore, this well should be placed along the east property line of the site and downgradient of fuel tanks. This well and the monitoring well proposed in number 2 above will also be useful to establish the hydraulic gradient or slope of the water table aquifer across the site. 4) Water-level measurements should be collected monthly for the first year and quarterly thereafter to evaluate seasonal variation in water elevation and potential hydraulic connection between the drift and Prairie du Chien aquifers. 5) LBG agrees that ground-water samples should be analyzed for DRO. However, if gasoline is to be used on site, then GRO, and potentially benzene, should be added to the list of analytical methods. 6) A door-to-door survey should be conducted to confirm "assumed well" locations shown on Figure 2. This is requested in Section F of the CUP application on page 3. Watershed District Review of Surface and Ground Water Issues The Carnelian-Marine-St. Croix Watershed District (CMSCWD) Engineers have recommended that the District Managers approve a Permit for Bracht Brothers Mining Operation, and authorized the District Administrator to issue permit contingent on Applicant addressing the comments of District Engineer. fhe Applicant will be required to obtain a permit from the CMSCWD before the City will issue the CUP for the Mining Operation. Traffic The entrances to the mining site are off 185th Street. From information provided by the applicant, the maximum traffic count is 50 trucks per day. Data from the past 17 years shows the actual average truck traffic has been lower at approximately 11 trucks per day. An additional two to four trips per day are expected from employees. The majority (95%) of this traffic will be oriented to and from the west on 185th Street toward County State-Aid Highway(CSAH) 3. 185th Street is a two-lane, gravel roadway. A `trucks hauling' sign is posted to the west of the site on 185th Street. The roadway also has warning signs posted for children and a supplemental speed of 30 mph. At the intersection with CSAH 3, where most traffic is headed, right turn lanes are currently provided for each approach on CSAH 3. The existing average annual daily traffic (AADT) volume is 2,050 vehicles per day on CSAH 3 and estimated to be much lower on 185th Street. A review of reported crashes showed only property damage crashes with animals. Given the low volume estimated on 185th Street, the relatively low volume on CSAH 3, and the relatively low volume to and from the site, roadway changes, such as turn lanes, are not recommended at this time. Scandia Planning Commission Page 6 May,2, 2008 Bracht Bros, Inc., CUP for Mining Recommendations • Another `truck hauling' sign should be added for the westbound approach to the east of the site. Supplemental signing below these new sign and the existing sign should also be added detailing the approximate number of feet until the first driveway. • As the truck traffic is likely the major source of traffic on the gravel road, dust control by the applicant is recommended. • Without lighting in the area and given the number of residences surrounding the site, hours of operation are also important to maintain safety. Restricting trucks to daylight hours, one hour before sunrise and one hour after sunset, or some other type of daytime limit, would provide benefits to traffic safety as well as overnight traffic noise. • Restriction of trucks to and from CSAH 3 is also recommended. This limits the impact of the truck traffic on local roadways. The County roadways are designed to handle the truck traffic. Although the applicant has stated that not much traffic is expected to and from the east toward Old Marine Trail, this would formalize the restriction. To preclude trucks using another local gravel roadway, the restriction should also include 177th Street. • Finally, by signage or some other method, the applicant should remind truckers of the low speed expected on 185th Street. The supplemental speed signs on the local road list 30 mph. Although the applicant cannot be held responsible for the individual speed of trucks, a reminder through a sign by the gate as trucks exit the site may help keep speeds low. Reclamation Plan The Scandia Mining Ordinance requires mining operators to provide a reclamation plan as part of their Conditional Use Permit Application (Chapter 4, Section 8). The plan must include graphic representation and written text. The Ordinance defines Reclamation, Restoration, Rehabilitation as follows: "To renew land to include re-establishment of vegetation, soil stability and establishment of safe conditions appropriate to the intended use of the land in accordance with the City's Comprehensive Plan and Conditional Use Permit conditions allowing for excavation and/or processing on the site." The ordinance further defines elements that must be present in the plan (intent of reclamation or final use, phasing and timing of reclamation, final condition of the site, etc.) timing concurrent with mining operation, requirements for grading and filling including final slopes, drainage, cover and planting, topsoil and removal of structures. If a mining operation will result in "accumulation of substantial water areas after reclamation" additional requirements such as water depths, grades above land as well as bottoms of water bodies are identified. In order to assure that the conditions of the reclamation plan are being addressed, renewal of the Annual Operators Permit (AOP) will in part depend on progress toward reclamation made on a yearly basis. To ensure that reclamation does occur in accordance with the approved plan, "the applicants are required to Scandia Planning Commission Page 7 May 2, 2008 Bracht Bros, Inc., CUP for Mining provide to the City an Irrevocable Letter of Credit or other security satisfactory to the City in the amount determined by the City." (Chapter 4 Section 9.3) The Bracht Mining Site is designated as General Rural - Agriculture Area in the Scandia Comprehensive Plan. The Plan states: "The General Rural/Agriculture Area is envisioned as an area that will remain sparsely developed over the next 25 years."The Scandia Zoning Ordinance designates the Bracht mining area as A-4 Agriculture. The two primary land uses in A-4 districts are Agriculture and Single Family Residential. Agricultural Use is defined as "Land whose use is devoted to the production of horticulture and nursery stock, fruit of all kinds, vegetables, forage, grains, bees and apiary products and raising domestic farm animals."The overall density of residential units is limited to four units per 40 acres. The range of potential final uses is limited to agriculture(includes open space) and single family residential at a density no greater than 4 units per 40 acres. If clustering (under the Open Space Conservation Subdivision provisions of the Zoning Ordinance) is proposed, a landowner may increase density slightly provided certain conditions are met. Evaluation of the Proposed Bracht Reclamation Plan The Bracht CUP mining application includes the following documents: 1) Conditional Use Permit Application for a Mining and Processing Operation, Section R, Reclamation Plan in Conformance with Section 8 2) Cl Site Plan (dated 4/10/08) 3) C3 Reclamation Plan (dated 4/15/08) 4) C3-A Restoration and Phasing Plan (dated 4/15/08) 5) C7 Concept Ultimate Use Plan (dated 4/7/08) The Bracht reclamation plan submitted as part of the CUP application addresses the ten points listed in the ordinance (Section 8.1) in text and graphic materials. The reclamation plan states the purpose of reclamation activities is to "restore the site to a stable condition, minimize the potential for erosion and allow for future development of the site." The plan with revisions on updated plans describes the methods and process of reclamation, including prescribed seed mixtures for long-term soil/slope stabilization. It addresses phasing and timing of operations and reclamation, and shows final condition of the site. It includes a detailed description of the reclamation costs, which are estimated at $63,914 in 2008 dollars. The ordinance states that reclamation is to proceed concurrently and proportional to actual mining operations. The plan does propose a mining schedule, although since nearly the entire mining area has been opened up, the reclamation plan will need to proceed on a timed basis. The ordinance lays out requirements for excavations resulting in the accumulation of substantial water areas after reclamation. The text does state that"the site will drain internally with ponding areas located within the .claimed areas." The final reclamation plan does not show where these ponds will be, although they will likely be in the low spots on the contours. The applicant must refine the extent and location of these Scandia Planning Commission Page 8 May.2, 2008 Bracht Bros, Inc., CUP for Mining proposed ponding areas. The reclamation plan states that all excavation areas will not get closer than 10 feet to the groundwater (910 feet above mean sea level). Thus final grades will not be lower than 920 feet. Section 8.4 of the Mining Ordinance lays out requirements for areas which must be graded or backfilled for final reclamation. The reclamation plan states that all overburden and topsoil needed to reclaim the parcel is available on site. A soil balance was prepared for Washington County,but that has not been provided to the City. Since the applicant is not proposing to import topsoil or overburden, no inspections of either will be required. Since there is reference to ponding areas, there could be stagnant water. This must be addressed. The area is to be contoured to a gently rolling topography. The plan states that the maximum slopes will be 4:1, and if sufficient material is left over, the slopes will be reduced. The ordinance states (8.4(6)) "such topsoil shall be planted with trees, shrubs, legumes or grasses." The reclamation plan only proposes grasses, even though the already reclaimed areas have grasses and scattered trees. The final elevations planned for building purposes must not be less than 10 feet above the normal ordinary groundwater level. Plans for on-site septic systems must be considered in these proposed elevations. Since most drainage from the site will remain on the site, it is not expected that there will be any adverse effects to public roads or neighboring uses. However, some areas outside the mining limits will be graded. Special care will be needed for grading outside the mining limits. Depending on where this occurs, it could limit locations for future residential uses. Section 8.7 of the Mining Ordinance addresses Topsoil. It prescribes the set aside of topsoil and overburden to minimize wind and water erosion. The reclamation plan states: "Consistent with the mining plan developed for this site for the County permits, the majority of restoration fill for the final restoration phase will come from the area east of the approved mining limits. As part of the County permitting process, soil balance computations were submitted and the area was reserved for use not as mining but as a source of restoration materials to ensure that sufficient restoration material would remain on the site." Section 8.8 of the Mining Ordinance addresses Structures. There are no permanent structures on the site. The plan does show equipment to be removed as part of final reclamation. Issues/Recommendations for Reclamation • The ultimate use concept plan shows four lots coming off a cul-de-sac that points west from a north/south road. The text of the reclamation plan states "this plan is conceptual only. Future development of the site will require formal review and platting by the appropriate governing agencies." The City of Scandia, by approving a reclamation plan, makes no promises or commitments relative to the concept plan. However, based on the concept plan, the City will expect the planned end use to be residential housing. The maximum number of residential units under current zoning is four units. The operator must make sure there are adequate areas for house pads and either on-site septic systems or a communal system. (The concept shows a joint sewer system.) Scandia Planning Commission Page 9 May 2, 2008 Bracht Oros, Inc., CUP for Mining • The reclamation plan states that no slopes will exceed 4:1, and depending upon the available overburden and topsoil remaining, the slopes will be less. The final slopes on this site cannot exceed 4:1. • The reclamation plan states a soil balance was prepared for this site. That information should be provided to the City. • No overburden or topsoil can be removed from this site, since the City would prefer final slopes less than 4:1. • The process for stabilizing the soil must use prescribed methods and seed mixtures as per the most current Mn/DOT Native Seeding Manual guidelines, as stated in the reclamation plan. • The separation between lowest final grades and groundwater cannot be closer than 10 feet. Since the Reclamation Plan acknowledges there will be ponding areas, they should be identified and the issue of stagnant water addressed. The ordinance calls for a combination of trees, shrubs, legumes and grasses. The reclamation plan only calls for grasses. Some of the areas already reclaimed include scattered trees. Today most of Scandia is a mixture of grasses, scattered trees and woodlands. In order to restore the area into the surrounding landscape, some native trees should be included in the reclamation/restoration plans. Language relative to final grades on Figure C3 should be revised: if fill is available the final grades may be "reduced". Staging: The reclamation plan states the anticipated life expectancy of the site is 10-15 years, depending on demand. The most recent Restoration and Phasing Plan is illustrated and explained on Figure C3-A dated April 15, 2008. This plan addresses phasing, although not timing of restoration. Visual inspection of the site indicates that there is need for catch up on some of the restoration activities. For this reason, the City recommends the following schedule for initial restoration phases, which will be enforced through the AOP process: • Phase 1 of future restoration activities will be establishing vegetation over this sloped and backfilled area (southwest corner, western half of mining phase 2). This should be accomplished in the 2008 season. • Phase 2 will be the completion of backfilling and sloping of the southeastern portion of the site(east half of mining phase 2) followed by establishment of vegetation. This should be accomplished in the 2009 season. • Phase 3 reclamation will involve sloping and backfilling the very western portion of the phase, followed by establishment of vegetation. This should be accomplished not later than the 2012 season, unless mining has not progressed as reported in the Annual Operating Permit application. • Final Reclamation Phase will require removal of all equipment, backfilling and grading in the northwest, northeast and eastern portions of the site. This will be followed by establishment of Scandia Planning Commission Page 10 May 2, 2008 Bracht Bros, Inc., CUP for Mining vegetation, including grasses and trees. This should be accomplished not later than the 2018 season, unless mining has not progressed as reported in the Annual Operating Permit application. • It is expected that the reclamation process will proceed concurrently and proportional to actual mining operations. Progress on concurrent reclamation as demonstrated in the AOP application, may allow reductions in portions of the Letter of Credit for Reclamation on a five-year basis. • Section 9.3 of the Mining Ordinance provides for a financial guarantee to the City to assure compliance with the Reclamation Plan. The guarantee can take the form of a Letter of Credit or other security satisfactory to the City in the amount determined by the City. The applicant has provided a detailed cost estimate for reclamation,based on the original reclamation plan submitted. This estimate of$63,914 (in 2008 dollars) should be verified by the applicant in light of the revised reclamation plan reviewed here. Assuming a 15 year life span, and an annual inflation rate of 3 percent, ultimate reclamation costs in 15 years would be $97,000. The Mining Ordinance does state that"the operator shall be entitled to a reduction in the security amount on a dollar for dollar basis as reclamation is completed and approved by the City engineer, except that the security shall not be reduced below an amount equal to 125 percent of the cost of the work to be completed as determined by the City Engineer nor below 5 percent of the security,unless the reclamation has been accepted by the City." • The Applicant must demonstrate that there is sufficient material on the site to complete the reclamation efforts. The City may increase the required financial guarantee if additional material needs to be imported to the site to complete the proposed reclamation. • The applicant must address these issues, and prepare a final, separate reclamation plan based upon these recommendations. That final reclamation plan, which will require approval by the City, will form the basis of future Annual Operating Permit approvals. This Reclamation Plan shall be updated every five years. Screening, Berming and Related Site Issues The updated site plan (Sheet C-1) provided by the applicant indicates the existing fencing that surrounds the site, and existing berming and plantings. No additional screening and berming will be required for approval of the CUP. The Reclamation Plan (Sheet C-3) has been revised to include the proposed seed mixes and maintenance for reclamation areas. These are appropriate and acceptable. Field visits to other mining sites revealed that reclamation efforts on some sites have experienced significant erosion on planted areas that has compromised the success of the reclamation efforts. It is recommended that erosion control fabrics or other geotextiles be incorporated as needed in reclamation areas to prevent erosion. Reclamation efforts will be monitored by the City, and where erosion issues are identified, the Applicant will be required to use appropriate methods to control erosion and assure the success of reclamation efforts. Scandia Planning Commission Page 11 May 2, 2008 Bracht pros, Inc., CUP for Mining PLANNING STAFF RECOMMENDATIONS: The proposed plans and supporting materials provided by Bracht Brothers, Inc., meet the requirements of the City's Code for issuing a Conditional Use Permit. The Planner recommends approval of the request for the Conditional Use Permit, with the following conditions: 1. The Applicant must comply with all rules and regulations of Federal, State, County, and local agencies, and maintain compliance with all permits granted by these agencies for operations on the site (ongoing). 2. The Applicant must receive a Stormwater Permit from Carnelian-Marine-St. Croix Watershed District (within 90 days of approval of the CUP). 3. The Applicant should provide information on existing ground elevations in bottom of pit on the plan sheet (within 60 days of approval of the CUP). 4.

The Applicant shall prevent trucks from using Old Marine Trail and 177th Street. 2. The applicant shall provide signs and verbal reminders to inform truckers of the low speed (30 mph) expected on 185th Street. 3. The Applicant should provide field delineation and report for the two wetlands adjacent to the pit. The Applicant should maintain an undisturbed buffer area of at least 50-ft from these wetlands until wetlands are delineated and potential impacts and requirements are determined. (Note: the delineation requirement can be included as a permit stipulation to be completed in Spring, 2008). 4. Another `truck hauling' sign should be added for the westbound approach to the east of the site. Supplemental signing below these new sign and the existing sign should also be added detailing the approximate number of feet until the first driveway. 5. The Applicant shall prepare a dust control plan as required in the City's Ordinance. The Applicant shall be required to provide dust control on gravel roads that are used for hauling, or provide an escrow to the City to provide at least two dust control treatments per year.

Senior Planner/Landscape Architect TKDA 1500 Piper Jaffray Plaza 444 Cedar Street St. Paul, MN 55101-2140 Re: Hydrogeologic Evaluation Aggregate Mining and Processing Operation Bracht Bros.,Inc. City of Scandia, Minnesota Dear Ms. Buss: Leggette, Brashears & Graham, Inc. (LBG) was retained by TKDA to review the Bracht Bros., Inc. (Bracht) Conditional Use Permit (CUP) Application for the purpose of identifying data gaps and any potential ground-water issues that could result from current and proposed mining activities. The information provided below provides TKDA and the City of Scandia (City), Minnesota with LBG's comments and recommendations. The CUP Application, dated November 2007, was prepared by Sunde Engineering, PLLC (Sunde) on behalf of Bracht for the aggregate mining and processing operation (site) located on 185`h St. in the City. The location of the site is shown on Figure 1. LBG conducted an initial review of CUP Application and related information in March 2008. From this review process, LBG identified specific portions of the CUP Application that required additional information and/or clarification on ground-water related issues. LBG prepared a series of questions that outlined these data gaps, which were submitted to Sunde through TKDA. At the time of our initial review, the information that was either missing or incomplete included: soil boring logs and survey data; a hydrogeologic cross section; historical ground-water level data; and, the water appropriation permit number for the on-site production well. Sunde responded in writing on April 15, 2008. LBG has reviewed this recent information and found that it sufficiently addresses our questions with the exception of the items presented in the general comments section below. Attachment 1 includes Sunde's responses to our questions and the supplemental information provided. CONNECTICUT•OHIO•ILLINOIS•SOUTH DAKOTA•PENNSYLVANIA•FLORIDA•NEW JERSEY•TEXAS WISCONSIN•NEW YORK•MISSOURI•VERMONT•MICHIGAN Ms. Sherri Buss 2 April 28,2008 General Comments 1) Sunde Responses to LBG Questions: The supplemental information provided by Sunde (see Attachment 1) in response to LBG's questions should be included in the CUP Application. 2) Section II- Figure 1 through 4: Sunde should include a scale bar on each map. 3) Section II - Figure 4: Sunde should include road names for reference. 4) Section II G - Figure C-1: Sunde should omit the two extra 105 contour lines on the east side of the map. 5) Section II 9 G - Figures C-4 through C-7: Sunde should revise cross section A-A' through D-D' to include tie lines (i.e. notes that show where cross sections intersect). A note should be provided on each cross section indicating the water table surface was estimated from borings drilled in 1989. 6) Section II 9 G - Figure C-7: Sunde should revise the "west" and "east" designations labeled on cross section D-D' to"north"and"south". 7) Section II 9 G - Ground-Water Elevations and Flow Direction: Observation wells have not been installed in the water table aquifer at the site. As a result, depth to the water table surface and the direction of ground-water flow in this aquifer was estimated by Sunde from on-site soil boring logs and information provided in the Washington County Geologic Atlas (Atlas) (Figure 2). Depth to ground-water and grade elevations noted on the boring logs from 1989 indicates the ground-water elevation decreases from 915 feet above mean sea level (amsl) on the west side of the site to 905 feet amsl on the east side. Although the borings were drilled in a line which is not ideal for determining ground-water flow direction, the general west to east flow direction agrees with the data provided in the Atlas. LBG concurs with the information presented in the CUP Application that the horizontal flow component of the water table aquifer is generally from west to east across the site. Ground-water levels in a shallow, water table aquifer can vary significantly over time because of changes in precipitation and recharge. Frequent monitoring of water levels and comparison to precipitation records is needed to establish seasonal variations and long-term trends. 8) Section II 9 G- Hydraulic Connection of Sand and Gravel and Bedrock Aquifers: Determining the hydraulic connection between different aquifers requires review of quality geologic logs, and collection and evaluation of ground-water level data. The boring logs from the site show the geology consists of three units. From top to bottom these include: 1) a sand and gravel unit; 2) a clay layer; and, 3) bedrock of the Prairie du Chien Group and Jordan Sandstone formations. The sand and gravel is the unit being mined and includes the water table aquifer. Based on current information, the water table surface is below the elevation of the existing and proposed mine floor. Geologic logs from soil borings 2 and 3 show the clay is approximately 18 feet thick and may act as a confining unit that hydraulically separates the sand and gravel aquifer Ms. Sherri Buss 3 April 28,2008 c from the underling Prairie du Chien-Jordan aquifer. The production well pumps from the Prairie du Chien-Jordan. Historical ground-water level data from the sand and gravel aquifer and the underlying Prairie du Chien-Jordan aquifer are currently unavailable to accurately evaluate the hydraulic connection between these water-bearing units on site. Ground-water elevations estimated from the borings in 1989 ranged from approximately 905 to 915 amsl. (Note: Since observation wells were not constructed in these borings, these water-level results represent a one-time measurement that cannot be repeated or confirmed.) The hydraulic head in the Prairie du Chien-Jordan below the site was not available until 1992 when the production well was installed. At that time depth to water was 26 feet below grade, but no survey results were available to establish a ground-water elevation. A subsequent survey completed by Landmark Surveying, Inc. (date unknown, but data was included in Sunde's April 15, 2008 response in Attachment 1) reported a grade elevation at the production well of approximately 939 feet amsl,which puts the ground-water elevation at approximately 913 feet amsl. This is similar to the water-table elevation estimated from the on-site borings. As stated in the CUP Application, the Atlas shows the hydraulic head of the Prairie du Chien-Jordan aquifer at approximately 880 to 890 feet amsl, which is approximately 25 feet below the estimated head in the sand and gravel aquifer. These results suggest the two aquifers may not be connected(Figure 2). Considering the lack of historical water elevation data from the sand and gravel aquifer, and conflicting results shown by the Atlas and site-specific data, it cannot be determined at this time if the two aquifers are connected. If the production well and is to be used for monitoring water table conditions,this condition must be addressed. 9) Section II 9 P: The production well is completed in the Prairie du Chien-Jordan aquifer, which may not be hydraulically connected to the sand and gravel aquifer that underlies the site. In addition, the portion of the production well (59 to 75 feet below grade) that is open to the bedrock aquifer is below water table surface. Monitoring below the water table may not provide accurate information. 10) Section II 9 P: The CUP Application states that a diesel range organics (DRO) test monitors for contamination from diesel fuel and other petroleum based products. Although this is correct, DRO does not identify the full gasoline range organics (GRO) spectrum. If gasoline is to be stored on site, then GRO and benzene should be added to the list of analytical methods. 11) Section III 7: Ground water will be increasingly vulnerable as the depth of the excavation increases. In addition, if at any location in the mine the clay unit is absent, then the Prairie du Chien-Jordan aquifer will also become increasingly vulnerable. This is simply due to the vertical proximity of the mine base and the water-table or Prairie du Chien aquifer systems. Ms. Sherri Buss 4 April 28,2008 Recommendations Given the general comments above and from our review of the CUP Application and subsequent information provided by Sunde,LBG recommends the following for this site. 1) LBG recommends that the production well not be used to meet the monitoring well requirements outlined in the CUP Application. LBG recommends that Bracht install a monitoring well that is adjacent to the production well and screened in the upper part of sand and gravel aquifer. The purpose of this well is to measure the depth to water in this uppermost water-bearing unit. Comparing water-level data from this well with the production well will also help determine the hydraulic connection between this aquifer and underlying the Prairie du Chien-Jordan aquifer. 2) LBG recommends that Bracht document when the wash plant operates to better identify when the production well is pumping. This information is necessary when evaluating water level data. 3) In addition to the shallow observation well proposed near the production well, the CUP Application requires not less than one downgradient monitoring well be installed (Section II P). Therefore, this well should be placed along the east property line of the site and downgradient of fuel tanks. This well and the monitoring well proposed in number 2 above will also be useful to establish the hydraulic gradient or slope of the water table aquifer across the site. 4) Water-level measurements should be collected monthly for the first year and quarterly thereafter to evaluate seasonal variation in water elevation and potential hydraulic connection between the drift and Prairie du Chien aquifers. 5) LBG agrees that ground-water samples should be analyzed for DRO. However, if gasoline is to be used on site, then GRO, and potentially benzene, should be added to the analyte list. 6) A door-to-door survey should be conducted to confirm"assumed well" locations shown on Figure 2. This is requested in Section F of the CUP application on page 3. 7) The recommendations provided above do not include those presented in a Memorandum by Emmons & Olivier Resources (EOR), dated March 31, 2008. LBG recommends that Bracht comply with the EOR's ground-water related recommendations as well.

Here is the summary of questions for the three Scandia mine sites. This summary focuses on data that is missing and required for us to complete our evaluation. Other LBG comments and proposed contingencies/recommendations pertaining to each CUP will be provided at a later date. Bracht 1) Are there survey data for the 3 borings(i.e.,grade elevation at the boring location when it was drilled)? if so,please provide. This will help determine/verify the accuracy of the groundwater elevations used to estimate flow direction. Landmark Surveying provided grade elevation at the soil boring locations at the time of drilling. The elevations are indicated on the attached boring logs. 2) How were the groundwater elevations established as indicated in Section 0 on pages 5 and 6? Were they estimated solely from the Washington County Atlas? Based on the soil boring information,groundwater elevations within the Quaternary Drift Aquifer beneath the site range from about 905 in the eastern portion of the site to 915 in ' the western portion of the site. This is consistent with information contained within the Washington County Geologic Atlas. Groundwater elevation information was obtained from the Washington County Geologic Atlas and the three soil borings that were drilled on the site. Groundwater levels on the Site Plan and Cross-Sections have been modified slightly to reflect the water levels from the soil borings instead of the Geologic Atlas. The direction of groundwater flow indicated by both the information in the Washington County Geologic Atlas and the soil borings is to the east towards the St. Croix River. 3) Please provide boring logs for the 3 borings shown on plate Cl. The CUP indicates the boring logs are included with Appendix 3. We did not receive Appendix 3. Copies of the boring logs are attached. 4) What time of year(month)were the borings drilled if not indicated on the logs? The borings were drilled May 31 —June 1 1989. 5) Where the borings completed as temporary piezometers that depth the groundwater levels were measured? If,so are there survey data for these wells and provide a map showing there locations. No,they were simply borings, not piezometers. 6) What time of year were the initial depth the groundwater levels estimated in the borings or wells? The groundwater levels were estimated at the time the soil borings were drilled, prior to cave-in on May 31-June 1, 1989. 7) Section 01,page 6, 3`d paragraph: What is "separating"the drift aquifer from the Prairie du Chien--Jordan at this site?Is this based on local or regional data provided in the Washington Co. Atlas?(Note, this may be explained after we review the boring logs) This is based on information in the Washington County Geologic Atlas which indicates that the Potentiometric surface of the Prairie du Chien Jordan aquifer is approximately 880-890 feet above mean sea level at the site and the Quaternary Drift is at approximately 910 feet above mean sea level at the site, indicating at least some degree of hydraulic separation. Further review of adjacent well logs indicates that there tends to be a substantial amount of clay layers within the drift in this area which can create the separation. However, area wells are typically finished in the Jordan and while some of the water levels match the County potentiometric surface map quite nicely, not all of them do, leaving open the possibility that there is at least some degree of hydraulic connection between the two aquifer systems. 8) Are there any site-specific groundwater level comparisons between the drift aquifer(sand and gravel)and the underlying Prairie du Chien—Jordan (i.e. from monitoring wells)? Tabulated values or well hydrographs would be sufficient. We have approximate water levels of the drift aquifer from the time the soil borings were drilled, May and June 1989 and we have an approximate water level of the Prairie du Chein-Jordan aquifer at the time the well was drilled, in February 1992. Water levels could vary substantially from year to year,therefore the available data do not provide a direct comparison of water levels in the two aquifer systems. A copy of the production well log is attached. 9) LBG is missing cross-sections A-A'and D-D'from plates C4 and C7. Copies of Cross Section A-A'and D-D' are attached. 10) Please provide any historical groundwater levels for the on-site water supply well and any associated survey data. The well log indicates that when the production well was drilled on February 28, 1992, groundwater level was 26'bellowgrade. According to a survey from Landmark surveying the well is at an elevation of 938.7. However, it is not known if this shot represents a ground shot or a top of well shot. The County permit required annual sampling from this well, but did not require any groundwater level data be collected. 11) Is on-site water supply well actually located where the CWI has it shown on Figure 2? Please provide a map with the location of the water supply well. The revised Site Plan, Figure C1 illustrates the location of the production well. 12) Provide a cross-section location map. The section location map is indicated on Sheet C4. 13) Please provide the appropriation permit number for the Bracht water supply well. The water appropriations permit number is 92-6231. A copy of the Permit is attached.

Reclamation Phasing C-3A: Attached is a reclamation phasing plan that illustrates where reclamation has occurred and the phases of future reclamation. Because this site is so small, the majority of the central and northern portions of the site (mining phases 1 and 3) will remain open to accommodate processing and stockpiling areas. The approved reclamation plans that the site has been operating under for the past several years have always indicated that the majority of fill for reclamation will come from the eastern portion of the site, outside of the mining limits. This area will be graded as part of final reclamation activities to establish final reclamation grades and include removal of the eastern screening berm. 2. Soil Balance calculation: A part of the original permitting of this site, a soil balance calculation was performed. This information is attached. 3. Seed Mixtures: The Reclamation Plan, Sheet C-3 has been revised to include the seed mixture and maintenance. 4. Traffic Information: The table illustrates below the estimated average daily traffic from the Bracht site is 6-7 trucks per day based on the last five years production rates.

Consulting Civil Engineers Sunde Engineering, PLLC 10830 Nesbitt Avenue South • Bloomington,Minnesota 55437-3100 Phone: (952)881-3344 • Fax: (952) 881-1913 • E-Mail: info@sundecivil.com BRACHT BROS., INC. APPLICATION FOR CONDITIONAL USE PERMIT GRAVEL MINING, CRUSHING AND WASH PLANT OPERATIONS CITY OF SCANDIA, MN INTRODUCTION Bracht Bros., Inc. currently owns and operates a gravel mining operation in the City of Scandia, MN. Mining of gravel at the site predates any type of permitting requirements. However, more recently the site has been issued five year permits from Washington County (since 1991) as well as annual permits from New Scandia Township. The following permit application is submitted on behalf of Bracht Bros., Inc. (Bracht) in compliance with the City of Scandia's Ordinance No. 103 and Chapter 4 of the Development Code: Mining and Related Activities Regulations adopted by the City of Scandia on August 28, 2007. II. SITE INFORMATION 1.) Name and Address of Operator and Land Owner: Bracht Bros., Inc 8303 216th Street North Forest Lake, MN 55025 2) An accurate legal description of where the mining shall occur: The legal description is included in Appendix 1. The mining site is 40 acres in size. However, only about 25 acres are permitted for mining. 3) Names and addresses of adjacent property owners within 1/2 mile of the perimeter of the area being or to be mined: A list of all property owners within a 1/2 mile of the perimeter of the area to be mined has been provided under separate cover. 4) A narrative outlining the type of material to be excavated, mode of operation, estimate of amount of material to be removed, plans for blasting, estimated time to complete the removal, and other pertinent information to explain the request in detail: Operations at the site are typical of sand and gravel mining operations. Extraction of sand and gravel is achieved with loaders. Material is crushed on site using a portable crusher that is periodically brought to the site. When the stockpiles of crushed material are depleted, the crusher is brought back to the 1 site for additional processing. A washplant, including conveyors, screens and a supply well, are located on site in the lower portion of the mine floor. Washing removes the fine particles associated with the sand and gravel. No chemicals are used in the washing process. Water discharged from the wash plant is directed to sedimentation ponds. The fine materials settle out and the water is recycled back to the wash plant. The wash plant operates with recycled water about 80% of the time. The sedimentation ponds are dredged out periodically to remove material that has accumulated at the bottom of the ponds. This periodic maintenance restores the storage capacity of the ponds. The dredged material is used for reclamation. A Minnesota Department of Natural Resources Water Appropriations Permit is obtained on an annual basis. Other activities include stockpiling, sale of materials and reclamation activity. There is an estimated 10-15 years of mining activity remaining at the site, depending upon market demand. Annual production is approximately 15,000 cy/year. There is no blasting at this site. Storm water runoff collects in the sedimentation ponds and at the lower portions of the mine floor. The runoff collects and then infiltrates the underlying sandy soils. 5) Fee: The required application fee has been submitted under separate cover. 6) Survey indicating property boundaries: A survey of the site including property boundaries is included as Sheet C1, Site Plan. 7) Map of property indicating where mining is to occur and other significant features as required in Ordnance 103: Sheet C1, Site Plan, illustrates the site property lines, limits of proposed excavation, setbacks, and topographic data at two-foot vertical intervals. Water- courses, wetlands, wooded areas, rock outcrops, power transmission poles and lines, and other significant features are also shown. 8) General Location Map and Aerial Photo: A General Location Map, an Aerial Photo and a USGS Quad Map Excerpt, are included as Figures 1-3, respectively. These figures show the existing mining site in relation to the community. 9) Maps and Plans showing the following for the site and within 300 feet of the perimeter of the mine: 2 A.

The locations of natural land features are illustrated on Sheet C1, Site Plan. E. Manmade features such as buildings and other structures, dams, dikes, and impoundments of water. Man-made structures are indicated on Sheet C1, Site Plan. F. Adjacent land features with all of the requirements included above within 300 feet of the perimeter of the mine, and all platted subdivision lots, metes and bounds parcels, and homes within '/4 mile of the property boundaries. Wells should include private/agriculture, industrial, municipal wells within '/2 mile radius of the mine. Adjacent land features are shown on Sheet C1, Site Plan. Homes within 'A mile and wells within '/ of the site are shown on Fig. 2. All platted subdivision lots, metes and bounds parcels, and homes within 1/4 mile of the property boundaries are indicated on Figure 4. 3 G. A minimum of 1 cross section for every 1000 feet running north/south and east/west, showing the extent of overburden, extent of sand and gravel deposits, the groundwater level, and any evidence of the groundwater level in the past. A series of four cross sections that depict the existing elevation, overburden, final elevations, extent of deposit, and the elevation of the groundwater are included as C4 -7. Three soil borings were completed as part of the original permitting process. The soil borings were used in developing the site cross sections. H. All processing areas and boundaries shown to scale. Processing areas are identified on Sheet C3, Site Plan. All access roads within the site to processing and mining areas shown to scale: Access Roads to the processing and mining areas are indicated on Sheet C1, Site Plan. J. Sequences or phases of operation showing approximate areas involved shown to scale and serially numbered with a description of each. Phasing is indicated on the Mining and Phasing Plan, C2. K. Location of screening berms shown to scale, and notes provided indicating when they will be used as reclamation material. In the same manner overburden storage areas must be identified and noted. Landscaping has been completed in accordance with plans previously approved by Washington County in 1991. There are a number of berms located around the property and trees planted around the perimeter of the property provide screening from adjacent land uses. Many trees were planted several years ago and have become well established and provide excellent screening. The location of screening berms and overburden stockpile areas are indicated on Sheet C1, Site Plan. L. Fences and gates and their type or construction described and illustrated: 4 Fences and gates are indicated on Sheet C1, Site Plan. A three strand barbed wire fence is in place around the perimeter of the site. Locking gates are located at the entrances to the facility. M. Proposed location of principal service or processing buildings or enclosures as well as locations of settling basins and process water ponds: Wash water ponds are indicated on Sheet C1, Site Plan. There are no buildings located on site. N. Existing site drainage features and flow directions indicated. A plan for handling surface drainage during operation and after final reclamation, consistent with local surface water management plans. Surface runoff is contained within the site. The runoff collects and infiltrates into the underlying soils. Erosion control measures used at the site include establishment of vegetation on perimeter berms. Erosion and sedimentation control practices after final reclamation include achieving permanent stabilization of the site through proper reclamation design standards. After mining is completed, reclamation will be performed to restore the site to a stable condition, minimize the potential for erosion and allow for future development of the land. Reclamation will involve slope stabilization, seeding and mulching. The Reclamation Plan, Sheet C3, indicates proposed site elevations upon completion of restoration. Slope stabilization will be accomplished by backfilling and grading the side slopes to a maximum of 4:1 (horizontal to vertical). A minimum of four inches of loamy soils, suitable as topsoil, will be placed on the graded slopes. After topsoil has been placed, the slopes will be seeded and mulched to establish vegetation. Reclaimed area will be planted with a mix of native trees, shrubs, grasses, flowers and groundcover. O. A plan for groundwater quality protection to include a minimum of three soil borings showing depth to groundwater. 1. HYdrogeologic Setting: The bedrock subcrop beneath the site is eroded surface of the Prairie du Chien Group and the Jordan Sandstone. The Washington County Geologic Atlast indicates that the site is located over a small, buried valley. The Jordan Sandstone likely forms the bedrock subcrop over the northwestern portion of the site. The Prairie du Chien Group forms the subcrop in the southeastern portion of the site. At the location of the wash plant well, about 16' of eroded Prairie du Chien Group remains over the ' Geologic Atlas- Washington County,Minnesota.County Atlas Series C-5. ed. Lynn Swanson and Gary Meyer, Minnesota Geological Survey,University of Minnesota St.Paul. 1990 5 Jordan Sandstone. The elevation of the bedrock subcrop at this location is approximately 860 feet above mean sea level. Three soil borings were drilled at the site in 1989 in conjunction with the County permitting process. The soil borings were used to establish the depth of topsoil in undisturbed areas of the site, elevation of the groundwater, and the extent of gravel reserves at the site. Each of the borings extended to the water table. Soil borings are included as Appendix 3. The first groundwater contact beneath the site is associated with the Quaternary Drift Aquifer. Groundwater beneath the site within this aquifer flows to the east towards the discharge region of the St. Croix River Valley. The Washington County Geologic Atlas indicates a relatively strong gradient to the east of 100' per mile. Groundwater contours are indicated on C1, Site Plans. Based on available information, Big Marine Lake appears to be a reflection of the water table surface. Beneath the glacial sand and gravel is another source of groundwater associated with the Prairie du Chien-Jordan Aquifer. These two bedrock units are hydrologically connected and function as a single aquifer. In the area of the gravel pit, the Prairie du Chien-Jordan Aquifer is separated from the overlying Quaternary Drift water table aquifer. Plate 5 of 7 in the Geologic Atlas indicates that the Prairie du Chien-Jordan Aquifer exists under confined conditions with a hydraulic head of approximately 880-890 feet above mean sea level in the area of the gravel pit. This is about 25 feet below the water table's potentiometric surface. 2. Groundwater Protection: Mining will not occur within or below the ground water table. Mining is limited to an elevation of 920 feet above mean sea level. Over ten feet of soil will separate the water table from the land surface after final reclamation. All fuels are stored above ground with secondary containment. Fuel storage is limited to fuel needed to operate the wash plant and the crusher. The on-site well is sampled for hydrocarbons on an annual basis (see below). P. All mining operations must install one monitoring well. If the proposed mining operation will appropriate groundwater for use in mining operations, the operator shall install not less than one monitoring well down gradient of the mining operation. If the proposed mining operation will include mining into the groundwater table, not less than two monitoring wells shall be installed one up-gradient and one down- gradient of the mine. The wash plant supply well is sampled on an annual basis when the wash plant is in operation. Analysis is performed for diesel range organics (DRO). 6 This test monitors for contamination from diesel fuel and other petroleum based products. Results will be submitted to Scandia in the annual report. DRO's have not been detected above the minimum detection limit during any of the past sampling events. Q. If lighting is proposed, a plan for lighting the area must be provided. The plan must comply with all City ordinances pertaining to lighting. There is no site lighting. R. Reclamation Plan in conformance with Section 8. Reclamation standards as included in Ordinance No. 103 Section 8.3-8.8 will be followed. 1. Intent: The intent of reclamation activities covered in this section is to restore the site to a stable condition, minimize the potential for erosion and allow for future development of the land. 2. Methods and processes of reclamation: Reclamation will include backfilling to stabilize slopes at a maximum slope of 4:1, seeding and mulching. A minimum of four inches of loamy soils, suitable as topsoil, will be placed on the graded slopes. Topsoil shall be placed on the area to be reclaimed, and the area will be seeded within 6 months of completing the backfilling. Topsoil will come from on-site sources. After topsoil has been placed, the slopes will be seeded and mulched to establish vegetation. Seeding and mulching will be in accordance with Minnesota Department of Transportation (MnDOT) Standard Specification No. 3876 and 3882. The seed used will be MnDOT Seed Mixture 240 or approved equal. Type 1 mulch will be used. It should be recognized that portions of a given phase, for example, along borders of subsequent phases, within the processing and operations area and along haul roads, may be left at an intermediate stage of reclamation until completion is practical. 3. Initial condition of mining site: The site has been a mining site for decades. 4. Limits of various operational areas: The operational areas are indicated on the Site Plan, Sheet C1. 5. Phasing and timing of operations and reclamation including areas to be stripped of overburden: Phasing of mining operations is included on the Mining and Phasing Plan Sheet C2. The entire site has been stripped. Some reclamation activity has been completed. The north line of Phase 1 was backfilled to a 4:1 slope, topsoil was applied, and vegetation established. Mining has been completed in Phase 1, and the processing and operating area has been established at the base of this phase. The wash plant, 7 sedimentation ponds, and stockpiles are located on the pit floor, so additional backfilling and reclamation activities will not be possible until after completion of the mining operation. 6. Final Condition of the site, including proposed contours and landscaping: The Reclamation Plan, Sheet C3, indicates proposed site elevations upon completion of restoration. 7. Relation of final site condition to adjoining land forms and drainage features within '/ mile: The site will slope from 185th street towards the north and match existing topography in the northwestern portion of the site blending in with surrounding lands. The site will drain internally with ponding areas located within the reclaimed areas. 8. Relation of reclaimed site to planned or established uses of surrounding land: The land is designated general rural/agriculture with 4/40 densities. Surrounding land use is similarly guided. Established land uses are agricultural and rural residential in nature. 9. A plan for maintenance of reclaimed area: See Reclamation Plan, Sheet C3. 10. A detailed cost estimate of reclamation and maintenance: Reclamation costs for the area currently opened to mining activity are outlined below. The western portion of Phase 2 has been mined out. Overburden from the eastern portion of Phase 2 has been backfilled into the western portion of Phase 2. Application of topsoil and seeding will be done once mining is completed in Phase 2 and the remaining portion of Phase 2 is backfilled. Updated reclamation costs have been prepared which take into consideration the mining and reclamation activity performed to date. Reclamation costs are based on the following: • Phase 1 — mining completed, reclamation along the northern perimeter of the site completed, remaining area left open for processing and operations area. • Phase 2 — Mining will be completed in 1-3 years. Backfilling of the eastern % of Phase 2 is complete. Backfilling of the remaining portion of Phase 2 is required. Topsoil and seeding of the entire phase will be required. 8 Reclamation Costs 1. Backfilling of actively mined areas: 10.63 acres with average 6' backfill required = 102,898 cy 2. Dozer backfills at rate of 300cy/hr at unit costs of $120/hr for machine and operator [(102,898 cy)/(300 cy/hr.)]($120/hr.) = $41,159 3. 4" Topsoil (20A)(43,560 ft2/A)(4"/12"/ft)/(27 cy/ft3) = 10,755 cy @ $1.00/cy = $10,755 4. Seed and Mulch (20 acres)($600/acre) = $ 12,000 TOTAL RECLAMATION COSTS $63,914 These costs break down to just over $5,000/acre for areas requiring backfilling, topsoil and vegetation and just over $1,000/acre for areas requiring only topsoil and vegetation. These costs are comparable or higher than restoration security required by other permitting agencies throughout the metropolitan area. S. If blasting is proposed as part of the mining operations, the operator must indicate frequency, timing, size, duration and develop a blasting plan: Blasting is not performed at this site. T. A description of any processing operations including washing crushing, recycling and bituminous plants and concrete ready-mix plants. Overburden is removed from areas to be mined and is stockpiled on site and later used for reclamation of completed phases. Aggregate is excavated using front end loaders. Processing at the site generally includes crushing, screening, washing, sorting and stockpiling of aggregate, recycling of concrete and asphalt by crushing, and screening and stockpiling. The processing and production equipment operates under all applicable Federal, State and local air, water and noise quality standards. An on-site well was installed at the site on February 28, 1992. The well is 75 feet deep and is completed in the Jordan Sandstone. The 8" well supplies the wash plant with water. The well is active only during the construction season from about May 1- November 1. A Minnesota Department of Natural Resources (DNR) Water Appropriations permit was obtained for the well on 9 July 7, 1992. The permit allows withdrawal of 275 gpm. The water appropriations permit is issued annually. The well water is supplemented with wash water recycled through on-site sedimentation ponds. Sedimentation ponds receive washplant discharge, settle out fine materials and reuse the wash water. The pond volumes are maintained by periodically removing the buildup of sediments. III. OPERATING CONDITIONS 1. Setbacks: Mining, stockpiling or land disturbance activities, with the exception of screening, are setback 50 feet from an adjoining property line, 200 feet from an occupied structure, 100 feet from any contiguous property subdivided into residential lots of 5 acres or less, and 100 feet from any road right-of-way. 2. Fencing: The entire site is fenced with 3 strand wire fencing. Locking gates are located at the site access points. 3. Hours of operation: The site is operated from 7:00 a.m. to 7:00 p.m. Monday through Friday except holidays. Excavation and processing activities, or sale of material does not occur on Saturdays. However, maintenance activities do occur. Extended hours may be required periodically for situations such as emergencies, accelerated work schedules or weather delays. If operations are required beyond the 7:00 a.m. to 7:00 p.m. hours, or on Saturdays, Sundays or holidays, prior permission will be obtained from the City of Scandia in accordance with procedures set forth in Ordinance No. 103. 4. Screening: The site is operated in a manner to minimize the visual impact of the extraction and processing area on surrounding properties. Landscaping has been completed in accordance with plans approved by Washington County in 1991. There are a number of berms located around the property and trees planted around the perimeter of the property provide screening from adjacent land uses. Many trees were planted in the 1980's which have become well established and provide excellent screening of the site. 10 5. Dust control: Dust is generated by crushing and screening equipment, excavation and loading equipment, and vehicular movement. Processing areas are located at elevations lower than the surrounding terrain in order to minimize windborne dust leaving the site. 6. Noise: Noise is generated from processing activities, loading processes, and vehicular movement. Noise is minimized by conducting processing activities within the interior of the site at elevations lower than the surrounding lands. All activities are conducted so as to be in accordance with all Federal, State and County noise standards. Noise testing at the site has been conducted on two separate occasions. Results of both testing episodes show compliance. The first test was performed by the Minnesota Pollution Control Agency on October 20, 1992. The wash plant was in operation during this test. Monitors were set up on the north, west, and east property lines. David Braslau and Associates conducted the second testing episode on June 17, 1994. The crushing spread was in operation during this test. Monitors were set up on the east and west property lines. Testing was performed in order to determine compliance with MPCA requirements. The table below summarizes the MPCA standards and the levels measured in the field. Sound levels were well below noise standards in both cases. The readings were taken at the property line even though the standards actually apply at the receptors, which are located some distance form the property lines. The wash plant does not operate when the crusher is in operation.

Depth of excavation: The applicant proposes no change to the maximum depth of 920' above mean sea level that was established in the Washington County Permit in order to offer groundwater protection and the ability to restore the site. 8. Site clearance: Trees, stumps, roots and other vegetative material removed during site clearance or other activities will be disposed of by logging, chipping or other approved methods. They will not be buried on-site. 9. Appearance/condition: All buildings, plants and equipment at the site will be maintained in a neat condition. Weeds and other unsightly or noxious vegetation shall be controlled as necessary to preserve the appearance of the reclaimed areas. 10. Sanitary Facilities: Portable sanitary facilities are provided in the operating area. 11. Waste Disposal: Any waste generated from the operation shall be disposed of in accordance with Federal, State and County requirements. 12. Water quality monitoring: The on-site well is sampled on an annual basis for diesel range organics. Results will be submitted to the City as part of the annual report. 13. Fuel and chemical storage: All fuel stored on site is stored in accordance with Federal and State standards. 14. Contingency Response Plan: In the event of a fuel leak or spill, immediate action will be taken. If the spill or leak is active, measures will be taken to control or stop the spill. Available on-site equipment (loaders, dozers) will be used to contain and recover the spill. Additional cleanup equipment and personnel will be called in for assistance as necessary. 12 A spill that consists of five gallons or more requires that the MPCA State Duty Officer be immediately notified at 1-651 649-5451. Cleanup will occur in cooperation with the Minnesota Pollution Control Agency. 15. Added Provisions: The operator will comply with other such reasonable requirements that the City may find necessary to adopt for the protection of health, safety and welfare and/or prevention of nuisance. 16. Processing: The site operates permanent processing equipment in accordance with all Federal State and City air and water quality and noise standards. Processing equipment is screened from view from other properties and adjacent roads. Crushing equipment is placed on the floor of the facility and setbacks per Ordinance No. 103 are maintained between the processing equipment and the property lines. 17. Recycling: The site currently does not conduct recycling operations. If such operations are conducted in the future, they will meet the operating conditions of Ordinance No. 103. 18. Trucking Operations: The site accesses 185th Street North, a gravel city street. All loads leaving the site are loaded accordance with state law. Loose material is cleaned from the truck and tires prior to exiting the facility. Bracht currently maintains five trucks for hauling. Independent contractors also purchase material from the pit. IV.

Re: Summary of Review and Recommendations for Permit App. No. 08-005 Bracht Brothers Mining Operation, Scandia RECOMMENDATIONS We recommend Managers approve Permit and authorize Administrator to issue permit contingent on Applicant addressing following comments, to satisfaction of District Engineer: Summary of comments to be addressed prior to permit issuance: 1. For the required review fees a deposit of$1,250.00 has been received. Applicant is responsible for replenishing this deposit if it appears it will be insufficient to cover District �-- review costs. The estimated completion date for this project is 2025 +/-. The District's standard permit length is 1-year. Managers will need to determine duration District permit will be valid before it will need to be renewed. If permit length is longer than 1-year a minimum annual status update from applicant and site visit should be coordinated with Scandia CUP and issuance of Annual Operators Permit. Managers will also need to establish method to re-coup costs for annual reviews. 2. District surety still needs to be provided. The City of Scandia requires a surety as part of its Mining Ordinance CUP and Annual Mine Operators Permit. Managers should consult with City to see if an agreement can be made that District would not need to require a separate additional surety. Perhaps requiring the applicant to maintain a cash deposit with the District of some amount as part of the permit fee requirement would be acceptable. This would ensure that District would recoup on-going review fees, while any major issues could perhaps be addressed through coordination with the City's permit enforcement process. 3. The existing conditions site plan does not provide contours or other ground elevation information for the existing bottom of pit. This information is needed to verify that project has not been excavated within 3-feet of the groundwater table per current District requirements. Air photos of area appear to show water in bottom of pit. Provide information on existing ground elevations in bottom of pit on existing plan sheet. 4. The submitted information does not allow a clear evaluation of the potential to drain the two wetlands located adjacent to active mining operations but indicates that mining adjacent to Page 2 3/31/08 Bracht Brothers Mining Operation Summary of CMSCWD Review the wetlands has been completed and that inspections by the County and WCD have indicated no impact to the wetlands. Applicant will need to provide copies of those inspection reports. Provide field delineation and report for the two wetlands adjacent to the pit. Maintain an undisturbed buffer area of at least 50-ft from these wetlands until wetlands are delineated and potential impacts and requirements are determined. (Note: the delineation requirement can be included as a permit stipulation to be completed this spring). 5. Include in plans procedures for loosing of soil to restore Soil permeability prior to final planting and site restoration. Concern is that under the reclaimed condition if B soils are used as fill, (as currently proposed) and they are heavily compacted during placement, soils will function like C soils and runoff will increase. 6. Include measures to avoid tracking of sediment offsite through vehicle traffic in event that City road is paved in future. GENERAL COMMENTS AND BACKGROUND INFORMATION The Bracht Brothers Mining Operation is located on the north side of 185th Street, about 1/2 mile west of Old Marine Trail in Section 35, T32N, R2OW in the City of Scandia, MN (see Figure 1 for location map). The proposed project entails the continuation of gravel mining and processing activities on a 40 acre lot. The project includes crushing and washing of gravel and recycling of concrete and asphalt, but does not include an asphalt plant or pit dewatering. The project will disturb a total of 34 acres through mining to an elevation of 920 ft.; 30 acres of the site have been disturbed through past mining operations. The groundwater elevation is estimated to be about 910 to 905 ft. based on soil borings taken in 1989 (to date, soil boring information has not submitted to the District). Existing ground elevations of pit bottom need to be provided to verify current separation from groundwater for current mining activities. The site does not drain directly to an identified groundwater-dependent natural resource. Permit application is for completion of planned mining activities through complete restoration of vegetation for entire site. Any further proposed development of site following completion of mining activities will require a new permit application submittal and will need to meet the district permit requirements applicable at the time of submittal. The Carnelian Marine St. Croix Watershed District (District) initially provided review comments to Scandia on this project that primarily pertained to the completeness of information received by City to meet District permit submittal requirements, in our letter dated January 24, 2008. All remaining materials, needed for a complete District Permit Application for this project, were received on March 24, 2008. The District also provided input to Scandia during development of their Mining Ordinance in 2007.

No.: 13812.010 From: Sherri Buss, R.L.A. Routing: Date: May 2, 2008 SUBJECT: Dresel Contracting, Inc. - Conditional Use Permit Application for a Mining and Processing Operation MEETING DATE: May 6, 2008 LOCATION: Section 17, Township 32, Range 20 APPLICANT: Dresel Contracting., Inc 24044 July Avenue Chisago City, MN 55013 120-DAY PERIOD: June 12, 2008 ZONING: Agricultural District, Shoreland Overlay District ITEMS REVIEWED: Application, Plans BRIEF DESCRIPTION OF THE REQUEST: The Application is for a new Conditional Use Permit (CUP) for an existing sand and gravel mining operation located on 218th St. North in Scandia. The site has been actively mined since the 1960's. The operation had a previous CUP granted by Washington County, when the County exercised land use authority within New Scandia Township. Permitted activities included the mining and processing of aggregate, and the recycling of concrete and asphalt. The Applicant proposes to expand the mining and operations from those approved in the previous County permit. The site includes two parcels. The western parcel is 40 acres in size, and 31 acres are proposed for mining. This parcel is owned by Dresel. The eastern parcel includes 17 acres, and 5 of these acres are proposed to be mined. The eastern parcel is owned by Franklin and Marcella Roth. The total site area is 57 acres, and 35 of these are proposed for inclusion within the active mining limits. An Employee Owned Company Promoting Affirmative Action and Equal Opportunity Scandia Planning Commission Page 2 May 2, 2008 Dresel Contracting Inc., CUP for Mining Mining Operations The mining operation includes removal of overburden, excavation of sand and gravel, crushing, washing, screening, stockpiling of sand and gravel; recycling of concrete and asphalt products; and reclamation activities. The overburden is removed from areas to be mined, and stockpiled on the site for use in reclamation activities. The Applicant indicates that the site usually operates on a seasonal basis from mid- April to mid-November, depending on weather conditions. The aggregate is excavated using front-end loaders. Processing activities include crushing, screening, and stockpiling. The recycling of concrete and asphalt on the site also includes crushing, screening and stockpiling. The final product is loaded on trucks using front-end loaders and delivered to project sites. The main access route to and from the site is Lofton Avenue(County Road 1) to 218th Street North. Both Lofton and 218th Street are paved. The Applicant notes that blasting does not occur at the site. An estimated 750,000 - 1,000,000 cubic yards of aggregate reserves remain at the site. Annual production is variable, and the Applicant indicates that the life of the facility is dependent on market demand. The phasing plan identifies four remaining phases: la is along the north boundary of the site and would be mined concurrently with lb at the south along the entry drive; phase 2 is in the center of the site, and phase 3 is in the eastern 1/3 of the site. The Phase 1 a mining area and north boundary of the Dresel Site is adjacent to the Tiller Corporation site that is also requesting a Conditional Use Permit for Mining and related activities. As the two sites are mined, the Dresel and Tiller excavation areas will be joined across the boundary to form one large mining pit area. The application notes that soil borings on the site identified the water table at an average elevation of 919 feet. Excavation on the northern portion of the site is proposed to 920 feet. The Applicant indicates that surface water will be managed in accordance with the site's NPDES Stormwater Pollution Prevention Plan (SWPPP), and consistent with local watershed management plans. The SWPPP includes a variety of Best Management Practices (BMP's) to avoid discharge of untreated water from the site, minimize erosion and sedimentation, and stabilize the site at the conclusion of mining activity. Stormwater collects at low areas within the mining pit floor and infiltrates. The Applicant is proposing that groundwater monitoring be conducted on an annual basis at the site. One monitoring well will be drilled on the north end of the property. The well may function as the "down gradient" well for this property, and the "up gradient" well for the Tiller property. The site has some existing berms at the site entry, and wooded areas on the northwest and northeast corners of the site. The proposed Phase 3 mining area is adjacent two wetlands on the site. No additional screening is proposed. Scandia Planning Commission Page 3 May 2, 2008 Dresel Contracting Inc., CUP for Mining EVALUATION OF THE REQUEST The Applicant is requesting a Conditional Use Permit for a mining operation. The proposed use is governed by the City's Ordinance No. 103, Mining and Related Activities Regulations. This review evaluates the request for a CUP based on the City's Ordinance and materials submitted by the Applicant. Groundwater Issues LBG conducted an initial review of the CUP Application and related information in March 2008. From this review process, LBG identified specific portions of the CUP Application that required additional information and/or clarification on ground-water related issues. A series of questions that outlined these data gaps were submitted by LBG to Sunde Engineering through TKDA. Sunde responded in writing on April 23, 2008. LBG has reviewed this recent information and found that it sufficiently addresses the questions with the exception of the items presented in the general comments section in LBG's letter dated April 28, 2008 (attached). Key Groundwater-Related Issues 1) Ground-Water Elevations and Flow Direction: Observation wells have not been installed in the water table aquifer at the site. As a result, depth to the water table surface and the direction of ground-water flow in this aquifer was estimated by Sunde from on-site soil boring data that were drilled several years ago as part of the County permitting process. Sunde was unable to locate the boring logs. The borings were drilled in a triangular array, which is the best arrangement for determining ground-water flow. Sunde provided estimated ground-water elevations from the three borings in their April 23, 2008 response to LBG's questions. These elevations were based on grade elevations and depth to ground-water measurements from the engineer who prepared the County permit application (Attachment 1). These data show the ground-water elevation on site ranges from 918.6 to 919.6 feet, and flow appears to be east to west. However, the depth to water measurements were recorded only to the nearest foot making these measurements inaccurate when considering a water table elevation difference of only 1 foot between the three borings. As a result, the direction of ground-water flow at this time is uncertain. Furthermore, the Washington County Geologic Atlas (Atlas) does not provide enough detail in the vicinity of the site to conclude that flow is to the northwest and in the direction of the proposed monitoring well (Figure 2). The downgradient monitoring well proposed for the northwest corner of the site was placed with the assumption that ground-water flow is to the northwest, as is the case on the Tiller site. Based on the information currently available, LBG does not agree with this conclusion. In Sunde's response to LBG question #9 (Attachment 1), it was noted that a downgradient monitoring well will be installed to help define the ground-water flow direction, and this downgradient well will be the shared well with the Tiller site. Without ground-water elevation data from three or more monitoring wells completed in the same aquifer, the ground-water flow direction for that aquifer cannot be determined. As a result, it is unknown if the monitoring well proposed for the Dresel site will be downgradient of the quarry operations. Scandia Planning Commission Page 4 May 2, 2008 Dresel Contracting Inc., CUP for Mining 2) Monitoring Needs: The CUP Application states that the proposed down-gradient well will be monitored for diesel range organics (DRO) on an annual basis. DRO does not identify the full gasoline range organics (GRO) spectrum. If gasoline is to be used on site, then GRO and benzene should be added to the list of analytical methods. 3) Depth of Excavation Relative to Water Table: The water table surface indicated in cross section (in particular cross-section A-A') is very close to the proposed elevation of the mine floor. The CUP Applications indicates the excavation will be conducted to an elevation of approximately 920 feet amsl, which is only 1 foot above the estimated ground-water elevation of approximately 919 feet amsl. Considering the current uncertainty with the water table elevation below the site(i.e., single measurement from soil borings, unknown date, and inherent measurement error), LBG feels there is not enough evidence to support a 1-foot separation between the mine floor and water table. Fluctuations in ground-water levels may raise the water table above the base of the mine. Recommendations Given the general comments above, and from LBG's review of the CUP Application and subsequent information provided by Sunde, LBG recommends the following for the Dresel site: • There is insufficient information available to determine the ground-water flow direction in the sand and gravel water table aquifer. The water-level data presented from the three site borings indicates that ground water may flow from east to west. Therefore, LBG recommends that two observation wells (in addition to the shared Tiller observation well in the northwest property corner) be installed in the water table aquifer to determine the ground-water flow direction, and to assure that the shared Tiller well is truly a downgradient well for the Dresel site. Although the CUP Application requests only a minimum of one monitoring well, LBG recommends that three monitoring wells be installed because the soil boring information is inconclusive. In addition to establishing a flow direction, these wells can be used to monitor ground-water level fluctuations across the site which is important when considering the 1-foot separation distance between the water table elevation shown in cross section and the proposed excavation elevation. • Water levels should be measured in all wells monthly for 1 year and quarterly thereafter to determine seasonal variations in ground-water elevation and flow direction. Increased ground-water elevation may result in the water table rising above the proposed mine base elevation. • Figure 2 should be updated to illustrate the MN County Well Index wells in the vicinity of the site. This is in reference to Section II 9 F that states the MN County Well Index Wells are indicated on Figure 2; which, they are not. • LBG recommends that a survey be conducted within 1/2-mile of the site to identify potential wells not included in the MN County Well Index by August 1, 2008. • LBG agrees that ground-water samples should be analyzed for DRO. However, if gasoline is to be used on site, then GRO and benzene should be added to the list of analytical methods. Scandia Planning Commission Page 5 May 2, 2008 Dresel Contracting Inc., CUP for Mining Watershed District Review of Surface and Groundwater Issues The Carnelian-Marine-St. Croix Watershed District Engineers have recommended that the District Managers approve a Permit for Dresel Contracting Mining Operations, contingent on the Applicant addressing the comments of the District Engineer. The Applicant will be required to obtain a permit from the Watershed District as a condition of the CUP. Traffic Issues The access to this mining site is via 218th Street. From information provided by the applicant, the maximum traffic anticipated is 150 trucks per day plus employee trips. Additional data suggests an average of 19 or 39 trucks per day depending upon the exact output of the site. No information was presented on the directional distribution. However, all traffic to and from the site will use Lofton Avenue to the east of the site. 218th Street is a dead-end to the west of the site. At Lofton Avenue, it is also likely most traffic will be oriented to and from the south toward Trunk Highway 97. 218th Street is a paved, two-lane local roadway. `Trucks hauling' signs are posted to each side of the site. A single lane for all movements is provided at the intersection of 218th Street with Lofton Avenue. The existing average annual daily traffic (AADT) volume is 2,150 vehicles per day on Lofton Avenue and estimated to be much lower on 218th Street. A review of reported crashes showed only one rollover property damage crash from years 2000 to 2005. • Given the low volume estimated on 218th Street, the relatively low volume on Lofton Avenue, and the relatively low volume to and from the site, roadway changes, such as turn lanes, are not recommended at this time. Supplemental signing below the existing `truck hauling' signs is recommended to indicate the approximate number of feet remaining to the site access point. • Without lighting in the area and given the number of residences surrounding the site, hours of operation are also important. Restricting trucks to daylight hours, one hour before sunrise and one hour after sunset, is recommended for traffic safety as well as overnight traffic noise. Reclamation Plan The Scandia Mining Ordinance requires mining operators to provide a reclamation plan as part of their Conditional Use Permit Application (Chapter 4, Section 8). The plan must include graphic representation and written text. The Ordinance defines Reclamation, Restoration, Rehabilitation as follows: "To renew land to a self-sustaining, long-term use which is compatible with contiguous land uses and which process shall include re-establishment of vegetation, soil stability and establishment of safe conditions appropriate to the intended use of the land in accordance with the City's Comprehensive Plan and Conditional Use Permit conditions allowing for excavation and/or processing on the site." The ordinance further defines elements that must be present in the plan (intent of reclamation or final use, phasing and timing of reclamation, final condition of the site, etc.) timing concurrent with mining operation, requirements for grading and filling including final slopes, drainage, cover and planting, topsoil and removal Scandia Planning Commission Page 6 May 2, 2008 Dresel Contracting Inc., CUP for Mining of structures. If a mining operation will result in "accumulation of substantial water areas after reclamation" additional requirements such as water depths, grades above land as well as bottoms of water bodies are identified. In order to assure that the conditions of the reclamation plan are being addressed, renewal of the Annual Operators Permit (AOP) will in part depend on progress toward reclamation made on a yearly basis. To ensure that reclamation does occur in accordance with the approved plan," the applicants are required to provide to the City an Irrevocable Letter of Credit or other security satisfactory to the City in the amount determined by the City" (Chapter 4 Section 9.3). The Dresel Mining Site is designated as General Rural - Agriculture Area in the Scandia Comprehensive Plan. The Plan states: "The General Rural/Agriculture Area is envisioned as an area that will remain sparsely developed over the next 25 years." The Scandia Zoning Ordinance designates the Dresel mining area as A-4 Agriculture. The two primary land uses in AG district are Agriculture and Single Family Residential. Agricultural Use is defined as "Land whose use is devoted to the production of horticulture and nursery stock, fruit of all kinds, vegetables, forage, grains, bees and apiary products and raising domestic farm animals."The overall density of residential units is limited to four units per 40 acres. The range of potential final uses is limited to agriculture(includes open space) and single family residential at a density no greater than 4 units per 40 acres. If clustering (under the Open Space Conservation Subdivision provisions of the Zoning Ordinance) is proposed, a landowner may increase density slightly provided certain conditions are met. Evaluation of the Dresel Reclamation Plan The Dresel CUP mining application includes the following documents: 1) Conditional Use Permit Application for Mining and Processing 2) Reclamation Plan in Conformance with Section 8C1 Existing Conditions (dated 4/23/08) 3) C3 Mining and Reclamation Plan (dated 4/22/08) 4) C3 A Reclamation Sequencing (dated 4/23/08) 5) C7 Concept Ultimate Use Plan (dated 4/22/08) The Dresel reclamation plan submitted as part of the CUP application includes graphic and text submittals that address the ten points listed in the ordinance (Section 8.1). The reclamation plan states the purpose of reclamation activities is to "restore the site to a stable condition, minimize the potential for erosion and allow for future development of the site." The plan with revisions on updated plans describes the methods and process of reclamation, including prescribed seed mixtures for long-term soil/slope stabilization. It addresses phasing and timing of operations and reclamation and shows final condition of the site. It includes a detailed description of the reclamation costs, which are estimated at $76,960 in 2008 dollars. Scandia Planning Commission Page 7 May 2, 2008 Dresel Contracting Inc., CUP for Mining The ordinance states that reclamation is to proceed concurrently and proportional to actual mining operations. Although almost the entire mining area has been opened up, the reclamation plan does not propose a reclamation schedule. The Reclamation Plan states that reclamation will continue as mining progresses in the general sequence indicated on this plan. The plan shows Reclamation Area 1 in the northeast, Reclamation Area 2 in the east, Reclamation Area 3 in the southeast, Reclamation Area 4 in the Southwest, and Reclamation Area 5 in the northwest. The south side has been reclaimed, but substantial areas eroded since reclamation commenced. These areas will need to be fixed as a first priority. This mining operation proposes to merge with the Tiller operation to the north. Therefore, this area is not shown on the Reclamation Plan. This area will need to be addressed as part of final reclamation. The ordinance lays out requirements for excavations resulting in the accumulation of substantial water areas after reclamation. The text does state that "stormwater contacting exposed areas drains internally,"but the plan does not address any ponding areas within the reclaimed areas. The applicant must refine the extent and location of any proposed ponding areas. The reclamation plan states that the groundwater level at the site is 919 feet. The application is proposing to excavate to a depth of 920 feet. The CMSCWD recommends that at least a three-foot separation be maintained between the maximum excavation depth and the top of the ground water. Section 8.4 of the Mining Ordinance lays out requirements for areas which must be graded or backfilled for final reclamation. The reclamation plan does not address whether all overburden and topsoil needed to reclaim the parcel is available on site. If it hasn't been prepared, a soil balance must be prepared to determine whether adequate overburden and topsoil exists to complete the reclamation. If not, then the provisions of the Mining Ordinance relative to importation of soils and testing must be addressed. Since it is not clear whether there will be ponding areas, there could be stagnant water. This must be addressed. The area is to be contoured to a gently rolling topography. The plan states that the maximum slopes will be 4:1, and if sufficient material is left over, the slopes will be reduced. The ordinance states (8.4(6))" such topsoil shall be planted with trees, shrubs, legumes or grasses." The reclamation plan only proposes grasses. The final elevations planned for building purposes must not be less than 10 feet above the normal ordinary groundwater level. Plans for on-site septic systems must be considered. Since most drainage from the site will remain on the site, it is not expected that there will be any adverse effects to public roads or neighboring uses. Section 8.7 of the Mining Ordinance addresses Topsoil. It prescribes the set aside of topsoil and overburden to minimize wind and water erosion. The reclamation plan does not address whether there is adequate overburden or topsoil on site to complete the restoration. This information needs to be provided by the Applicant. Section 8.8 of the Mining Ordinance addresses Structures. There are no permanent structures on the site. Temporary equipment is brought in and used as needed. All equipment must be removed prior to final reclamation. Scandia Planning Commission Page 8 May 2, 2008 Dresel Contracting Inc., CUP for Mining Issues/Recommendations for the Reclamation Plan • The parcel owned by the operators consists of 40 acres, with 17 acres to the east leased by Dresel. The area is zoned A-4 Agriculture, which allows an overall density of one unit per 10 acres. A small portion in the southwest side of the property is within the Shoreland designation. The overall number of units possible on the site is five, although there is no plan shown for the leased property to the east. The 40 acres owned by the applicant shows the 40-acres cut east/west into two lots off a short cul-de- sac on the southeast corner of the property. A site inspection of the parcel indicated the most likely places for two houses would be in the southwest corner and the northeast corner. The concept should drop the cul-de-sac and run the two lots north/south. However, the City of Scandia, by approving a reclamation plan, makes no promises or commitments relative to the concept plan. Based on that plan, the City will expect the planned end use to be residential. The operator must make sure there are adequate areas for house pads and either on-site septic systems or a communal system. The reclamation plan states that no slopes will exceed 4:1, and depending upon available overburden and topsoil, the slopes will even be less. The final slopes on this site cannot exceed 4:1. • There is no indication from the information provided whether there is sufficient soil on site to reclaim according to the plan. A soil balance must be provided to the City to assure there are adequate resources to reclaim the site. If not, the applicant must demonstrate the additional volumes of material needed. • No overburden or topsoil can be removed from this site, since the City prefers final slopes less than 4:1. • The process for stabilizing the soil must use prescribed methods and seed mixtures as per the most recent Mn/DOT Native Seed Manual guidelines as stated in the reclamation plan. • The separation between the lowest final grades and groundwater cannot be less than those prescribed by the City. • The reclamation plan must identify if there will be any ponding areas when the land is ultimately reclaimed. • The ordinance calls for a combination of trees, shrubs, legumes and grasses. The reclamation plan only calls for grasses. Today, most of Scandia is a mixture of grasses, scattered trees and woodlands. In order to restore the area into the surrounding landscape, some native trees should be included in the reclamation/restoration plans. Staging: The reclamation plan does not specifically address the life expectancy of the mining operation, stating instead that it is entirely dependent upon demand. Scandia Planning Commission Page 9 May 2, 2008 Dresel Contracting Inc., CUP for Mining The reclamation plan is also generalized. It states that reclamation will proceed concurrently with mining operations. Reclamation activities which take place during the past mining season as well as reclamation activities planned for the subsequent mining season will be discussed in each annual report. In order to provide a time frame within which to conduct the reclamation, the City recommends the following timing for initial restoration phases, which will be enforced through the AOP process: • There is considerable erosion in areas reclaimed on the south and southwest of the site. The first priority is to stabilize this erosion. The operator should work with the Washington Conservation District to implement the best practices to end the erosion, including mesh with seeds or other effective methods. This should be accomplished the spring of 2008. • Reclamation Area 1 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2009 season. • Reclamation Area 2 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2009 season. • Reclamation Area 3 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2010 season. • Reclamation Area 4 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2015 season, depending upon progress of mining activities. • Reclamation Area 5 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2018 season, depending upon progress of mining activities. • Final Reclamation will include removal of any equipment, and any backfilling and seeding of the operations area. • It is expected that the reclamation will proceed concurrently and proportional to actual mining operations. Progress on concurrent reclamation as demonstrated in the AOP application, may allow reductions in portions of the Letter of Credit for reclamation on a five-year basis. • Section 9.3 of the Mining Ordinance provides for a financial guarantee to the City to assure compliance with the Reclamation Plan. The guarantee can take the form of a Letter of Credit or other security satisfactory to the City in the amount determined by the City. The applicant has provided a detailed cost estimate for reclamation, based on the original reclamation plan submitted. This estimate of$76,960 (in 2008 dollars) should be verified by the applicant in light of the more detailed reclamation plan reviewed here. Assuming a 15 year life span, and an annual inflation rate of 3 percent, ultimate reclamation costs in 15 years would be $111,600. The Mining Ordinance does state that "the operator shall be entitled to a reduction in the security amount on a dollar for dollar basis as reclamation is completed and approved by the City engineer, except that the security shall not be reduced below an amount equal to 125 percent of the cost of the work to be completed as detennined Scandia Planning Commission Page 10 May 2, 2008 Dresel Contracting Inc., CUP for Mining by the City Engineer nor below 5 percent of the security, unless the reclamation has been accepted by the City." • The Applicant must demonstrate that there is sufficient material on the site to complete the reclamation efforts. The City may increase the required financial guarantee if additional material needs to be imported to the site to complete the proposed reclamation. • The applicant must address these issues, and prepare a final, separate reclamation plan based upon these recommendations. That final reclamation plan, which will require approval by the City, will form part of the basis for approval of the Annual Operating Permit. This Reclamation Plan shall be updated every five years. Screening, Berrning and Related Site Issues The updated site plan (Sheet C-1) provided by the applicant indicates the existing fencing,berming and plantings. No additional screening and berming will be required for approval of the CUP. The Reclamation Plan (Sheet C-3) includes the proposed seed mixes and maintenance for reclamation areas. These are appropriate and acceptable. Field visits to this site revealed that existing reclamation efforts have experienced significant erosion on planted areas that is compromising the success of the reclamation efforts. It is recommended that erosion control fabrics or other geotextiles be incorporated where needed in reclamation areas, particularly in areas of concentrated storm water flows, to prevent erosion. Reclamation efforts will be monitored by the City, and where erosion issues are identified, the Applicant will be required to use appropriate methods to control erosion and assure the success of reclamation efforts. Bioengineering approaches that result in a natural appearance on the reclaimed areas should be utilized. Shoreland Issues Staff reviewed the Dresel Mine site plan in detail, and its relationship to the City's Shoreland Zone for German Lake. A portion of the existing "reclaimed area" in the southwest part of the site is within the Shoreland Zone. No mining is proposed within the Shoreland Zone, and is prohibited under the City's Shoreland Zone Ordinance. PLANNING STAFF RECOMMENDATIONS: The proposed plans and supporting materials provided by Dresel Contracting, Inc., meet the requirements of the City's Code for issuing a Conditional Use Permit. The Planner recommends approval of the request, with the following conditions: 1. The Applicant must comply with all rules and regulations of Federal, State, County, and local agencies, and maintain existing permits granted by these agencies for all operations at the site (ongoing).

City of Scandia,Minnesota Dear Ms.Buss: Leggette, Brashears & Graham, Inc. (LBG) was retained by TKDA to review the Dresel Contracting, Inc. (Dresel) Conditional Use Permit (CUP) Application for the purpose of identifying data gaps and potential ground-water issues that could result from current and proposed mining activities. The information below provides TKDA and the City of Scandia (City), Minnesota with LBG's comments and recommendations. The CUP Application, dated November 2007, was prepared by Sunde Engineering, PLLC (Sunde) on behalf of Dresel for the aggregate mining and processing operation (site) located on the west side of Lofton Avenue in the City. The location of the site is shown on Figure 1. LBG conducted an initial review of the CUP Application and related information in March 2008. From this review process, LBG identified specific portions of the CUP Application that required additional information and/or clarification on ground-water related issues. A series of questions that outlined these data gaps were submitted by LBG to Sunde through TKDA. At the time of our initial review, the information that was either missing or incomplete included: boring logs and a map showing their locations,Figure 2,the accuracy of ground-water elevations, survey data, and whether a water supply well was located on site. Sunde responded in writing on April 23, 2008. LBG has reviewed this recent information and found that it sufficiently addresses our questions with the exception of the items presented in the general comments section below. Attachment 1 includes Sunde's responses to our questions and the supplemental information provided including revised plan view maps (C1 and C2)and Figure 2. CONNECTICUT•OHIO•ILLINOIS•SOUTH DAKOTA•PENNSYLVANIA•FLORIDA•NEW JERSEY•TEXAS WISCONSIN•NEW YORK•MISSOURI•VERMONT•MICHIGAN Ms. Sherri Buss 2 April 29, 2008 General Comments 1) Sunde Responses to LBG Questions: The supplemental information provided by Sunde (see Attachment 1) in response to LBG's questions should be included in the CUP Application. 2) Section II 9 F - Figure 2: Wells from the MN County Well Index are not shown on Figure 2 as stated in the text. Sunde should include these wells and the findings from other well search sources. 3) Section II 9 G, 0, P - Ground-Water Elevations and Flow Direction: Observation wells have not been installed in the water table aquifer at the site. As a result, depth to the water table surface and the direction of ground-water flow in this aquifer was estimated by Sunde from on-site soil boring data that were drilled several years ago as part of the County permitting process. Sunde was unable to locate the boring logs. The borings were drilled in a triangular array, which is the best arrangement for determining ground-water flow. Sunde provided estimated ground-water elevations from the three borings in their April 23, 2008 response to LBG's questions. These elevations were based on grade elevations and depth to ground-water measurements from the engineer who prepared the County permit application(Attachment 1). These data show the ground-water elevation on site ranges from 918.6 to 919.6 feet, and flow appears to be east to west. However, the depth to water measurements were recorded only to the nearest foot making these measurements inaccurate when considering a water table elevation difference of only 1 foot between the three borings. As a result, the direction of ground-water flow at this time is uncertain. Furthermore, the Washington County Geologic Atlas (Atlas) does not provide enough detail in the vicinity of the site to conclude that flow is to the northwest and in the direction of the proposed monitoring well(Figure 2). 4) Section II 9 P- Downgradient Monitoring Well: The downgradient monitoring well proposed for the northwest corner of the site was placed with the assumption that ground-water flow is to the northwest, as is the case on the Tiller site. Based on the information currently available,LBG does not agree with this conclusion. In Sunde's response to LBG question #9 (Attachment 1), it was noted that a downgradient monitoring well will be installed to help define the ground-water flow direction, and this downgradient well will be the shared well with the Tiller site. Without ground-water elevation data from three or more monitoring wells completed in the same aquifer, the ground-water flow direction for that aquifer cannot be determined. As a result, it is unknown if the monitoring well proposed for the Dresel site will be downgradient of the quarry operations. 5) Section II 9 P: The CUP Application states that the proposed downgradient well will be monitored for diesel range organics (DRO) on an annual basis. DRO does not identify the full gasoline range organics(GRO) spectrum. If gasoline is to be stored on site,then GRO and benzene should be added to the analyte list. 6) Section II 9 N: It looks like the reclamation surface elevations are presented on Figure C3,not C4 as indicated in the text. Ms. Sherri Buss 3 April 29, 2008 7) Section III 7 - Depth of Excavation Relative to Water Table: The water table surface indicated in cross section (in particular cross-section A-A') is very close to the proposed elevation of the mine floor. The CUP Applications indicates the excavation will be conducted to an elevation of approximately 920 feet amsl, which is only 1 foot above the estimated ground-water elevation of approximately 919 feet amsl. Considering the current uncertainty with the water table elevation below the site (i.e., single measurement from soil borings, unknown date, and inherent measurement error), LBG feels there is not enough evidence to support a 1-foot separation between the mine floor and water table. Fluctuations in ground-water levels may raise the water table above the base of the mine. It is also unclear (see Comment #3 on Emmons & Olivier Resources Memorandum dated March 31, 2008) whether the base of the Dresel mine is to be included in the extension of a ground-water lake created on the Tiller site. Recommendations Given the general comments above, and from our review of the CUP Application and subsequent information provided by Sunde,LBG recommends the following for the Dresel site. 1) There is insufficient information available to determine the ground-water flow direction in the sand and gravel water table aquifer. The water-level data presented from the three site borings indicates that ground water may flow from east to west. Therefore, LBG recommends that two observation wells (in addition to the shared Tiller observation well in the northwest property corner) be installed in the water table aquifer to determine the ground-water flow direction, and to assure that the shared Tiller well is truly a downgradient well for the Dresel site. Although the CUP Application requests only a minimum of one monitoring well, LBG recommends that three monitoring wells be installed because the soil boring information is inconclusive. In addition to establishing a flow direction, these wells can be used to monitor ground-water level fluctuations across the site which is important when considering the 1-foot separation distance between the water table elevation shown in cross section and the proposed excavation elevation. 2) Water levels should be measured in all wells monthly for 1 year and quarterly thereafter to determine seasonal variations in ground-water elevation and flow direction. Increased ground-water elevation may result in the water table rising above the proposed mine base elevation. 3) Figure 2 should be updated to illustrate the MN County Well Index wells in the vicinity of the site. This is in reference to Section II 9 F that states the MN County Well Index Wells are indicated on Figure 2; which, they are not. 4) LBG recommends that a survey be conducted within 1/2-mile of the site to identify potential wells not included in the MN County Well Index. 5) LBG agrees that ground-water samples should be analyzed for DRO. However, if gasoline is to be used on site, then GRO and benzene should be added to the analyte list. Ms. Sherri Buss 4 April 29, 2008 The recommendations provided above do not include those presented in a Memorandum by Emmons & Olivier Resources (EOR), dated March 31, 2008. LBG advises that Dresel comply with the EOR recommendations as well. If you have any questions concerning this review,please contact us at (651)490-1405.

Concept Ultimate Use Plan: This plan illustrates one potential use of the property after reclamation. This plan is conceptual only. Future development of the site may be agricultural or some other development that is in accordance with land use regulations at the time of development. Future development will require a formal application and approval by the City of Scandia. la. Reclamation Phasing C-3A: Attached is a reclamation phasing plan that illustrates where slope stabilization has occurred and the sequence of future restoration areas. Backfilling and stabilization of sideslopes will occur as mining along the perimeter of the mining areas is completed. The floor of the mining area will continue to be utilized for processing and stockpile area throughout the life of the mining operation. Perimeter berms will be utilized in final restoration grading work. This plan will be reviewed and updated as needed as part of the annual operator's permit. 2. Soil Balance calculation: Clean soils are imported to this site and used for backfilling and restoration activity. The operator utilizes the various materials contained on-site on various local jobs. Excess soils from these jobs are backhauled to the site and utilized as fill material. Approximately 300,000 cy of material will be needed to complete restoration.

The table below illustrates the estimated average daily traffic from the Dresel site based on 50,000 cy/year and 100,000 cy/year. Material is also hauled into the site for recycling and reclamation activities. This material is typically brought into the site and then the truck is loaded with material to return to the job site so it does not represent additional truck trips.

The mining operation is situated on a 57 acre site in the City of Scandia. The site is located within two separate watershed districts, the Carnellian-Marine-St. Croix WD, which covers the western 3/a of the site and the Forest Lake-Comfort Lake WD, which covers the eastern 1/4 of the site. The boundary between the two watershed districts is not based on a watershed divide. It is established based on parcel boundary lines. Existing (Interim) Condition: The site has been actively mined for the past several years. The area to be disturbed by mining encompasses 35.5 acres. Approximately 31 acres within the mining limits has been disturbed from mining activity. Currently, the majority of the disturbed area drains internally to low areas within the site. Collected water infiltrates and evaporates and is not discharged from the site. The locations of these low areas move throughout the site as mining activity moves throughout the site. Screening berms have been established around the perimeter of the site. The outer portions of these berms drain off-site. Existing berms are stabilized with well established vegetation. Portions of the site have been stabilized by sloping and establishment of vegetation. There is a wetland located just west of the mining limits. According to the plans prepared as part of the Washington County permitting process for this site, the wetland was delineated in the field by Tim Fredbo water resource specialist, Washington Soil and Water Conversation District. The area adjacent to the wetland has already been mined. The area has been sloped and vegetation established to stabilize the slope. Hydrologic computations have been prepared which evaluate the current condition of the site as well as the final reclamation condition of the site. Essentially the current condition also represents the interim or operating condition of the site. Past mining has redirected original site drainage to an internally drained condition over portions of the site that have been mined. The interim condition will continue to change as the remaining portion of the site is mined to completion. The calculations illustrate the current sub-watershed areas and evaluate stormwater runoff entering the site, leaving the site, and remaining within the site. Curve numbers of the mapped soil types per the Natural Resources Conservation Service were used for all drainage areas except the pit (Drainage Area 1). The pit was assumed to be type "A" soils and a newly graded area Stormwater Management Calculations Dresel Contracting, Inc. 3/2008 New Scandia, MN NM which has a CN of 77. For the Final (Restoration) Condition, type "B" soils were assumed for a grassed area with greater than 75% grass cover (CN 61) for the pit. Final (Restoration) Condition: Final reclamation will leave the site as open space with the slopes and floor stabilized with established vegetation. There will be no increase in rates of runoff leaving the site into the various subdrainage areas outside of the limits of the Dresel and Tiller mining areas. Instead of draining internally, as in the interim condition, the perimeter slopes and floor of the reclaimed mining area will drain to the north to the water body created by the adjacent Tiller Corporation's mining operation. There will be no hard surfaces associated with the reclamation condition, therefore no permanent stormwater management facilities will remain on-site after reclamation. When final development eventually occurs on this site, appropriate stormwater management, sedimentation and erosion control plans will be prepared to reflect the proposed final development.

Proposed/Reclamation conditions offsite drainage does not exceed pre- development/existing conditions offsite drainage. Wetlands: There is one wetland basin located west of the proposed mining limits. The drainage area of this basin will be reduced as a result of mining operations. However, because the soils within the portion of the drainage area to be removed are permeable in nature, they result in very little runoff for the day to day storm events. Therefore, removal of drainage areas with permeable soils has very little impact during frequent day to day type rainstorm events. It is during less frequent (i.e. 100 yr) events where soils become saturated that there begins to be a substantial difference between the existing and proposed conditions. The analysis shows that for frequent rainstorm events, the impact to the wetland basin will not be significant. Because the more frequent events sustain the wetlands, there should be no substantial indirect impact to the wetland basins as a result of the mining operation.

Stormwater Management Calculations Dresel Contracting, Inc. 3/2008 New Scandia, MN NM With respect to specific items in the January 23, 2008 comment letter from the Comfort Lake Forest Lake Watershed District the following information is provided: 1) There is very little information provided in order to evaluate the site's overall impact on the surrounding environment with respect to the goals and policies in the Comfort Lake — Forest Lake Watershed Districts Watershed Management Plan: With respect to the policies of the Comfort Lake Watershed District, the site has operated and will continue to operate in a manner to protect adjacent wetlands and waters from significant degradation and to protect wetlands and waters from significant wetland alteration, to maintain existing water uses, aquatic and wetland habitats and the level of water quality. Specific District goals relevant to this site include water management and wetland management. Water management goals include preservation and use of natural storage and retention areas to control excess volumes and rates of runoff, preservation of groundwater recharge areas, measures to protect surface and groundwater quality, and monitoring of groundwater quantity and quality throughout the duration of mining operations. The site operates under a Stormwater Pollution Prevention Plan. This plan has been developed to prevent stormwater that has contacted stripped areas or exposed soils from discharging from the site untreated. The mining operation creates storage and retention areas helping to control excess volumes and rates of runoff. The majority of stormwater is infiltrated, preserving groundwater recharge areas. Groundwater monitoring will be conducted to insure protection of groundwater quality. Wetland goals include protection of District wetlands in accordance with existing rules and regulations using watershed based management activities and restoration. The wetland basin located west of the mining limits was field delineated as part of past permits with Washington County. Mining adjacent to the wetland has been completed. The excavation slope has been backfilled, sloped and stabilized with vegetation. 2) The site operates on two parcels on 57 acres of which 36 acres are within the active mining limits. No response needed. Stormwater Management Calculations Dresel Contracting, Inc. 3/2008 New Scandia, MN NM 3) Only one wetland indicated in the site plan has been field delineated. In order to determine the types, sensitivities, and overall values of the wetlands on site, they all should be field delineated. Further, CLFL WD recommends that all wetlands be protected with buffer zone to be maintained outside the outer wetland boundary. The site maps do not indicate buffer zones. The only wetland basin not delineated in the field is indicated as PUBGx on the NWI maps. According to the operator, this basin was created as part of the mining operation and has subsequently been removed through the course of additional mining. A minimum twenty foot natural vegetation buffer zone will be maintained around the existing wetland. Work adjacent to the wetland has already been completed in accordance with the permit from Washington County. The active mining face adjacent to the wetlands has been backfilled sloped and vegetated. Please refer to the Drainage and Erosion Control Plan for details. 4) There is no stormwater rate and volume modeling completed for the site. In order fulfill goals included within the District's Watershed Management Plan, interim and post-use (reclaimed)stormwater rates from the site for a 24-hour precipitation event with a return frequency of 2, 5, 10, or 100 years should not increase from pre-use conditions Further, increased runoff volumes can cause downstream flooding or exacerbate existing flooding concerns and can alter the hydrology of downstream wetlands. In order to alleviate these concerns and fulfill goals included within the District's Watershed Management Plan, the project site (existing, interim and reclaimed)should be designed to maintain existing runoff volumes for the 2-year event(2.8 inches). Stormwater rate and volume calculations have been preformed. The results are presented in the Existing/Proposed Conditions section of this report. Also, please refer to HydroCAD output for further detail. Exisiting conditions are the same as interim conditions as the site is currently operating. 5) There are no water quality models in order to determine pre-use, interim and post-use (reclaimed) phosphorus loads from the site. Submittal of a water quality modeling analysis of the site (using a model such as P8 or a method found in Appendix L of the Minnesota Stormwater Manual "Simple Method of Determining Phosphorus Export,"for determining the pre-use and post-use nutrient loads from the site) would specifically address this concern. Currently there are no water quality models modeling phosphorus removal and loads because modeling them is based on ponding. There is no ponding -~ Stormwater Management Calculations Dresel Contracting, Inc. 3/2008 New Scandia, MN NM proposed for the interim and post-use conditions for offsite drainage areas, therefore phosphorus loads are not able to be modeled. What can be said generally about the phosphorus loads from the site are that as mining continues to the north, east and west phosphorus loads leaving the site will be reduced as the drainage areas are reduced in size. Ultimately the reclamation condition will have less of a phosphorus load leaving the site than the pre-mining (with agricultural land uses) conditions. 6) The watershed will also request design and construction details for the proposed BMP's mentioned in N. as well as detail as to where and when those BMP's will be used. Please refer to the SWPPP and the Drainage and Erosion Control Plan for additional information. 7) In order to review the sites groundwater component/interaction, the watershed will request a copy of the groundwater monitoring p/an, spill response and emergency response plans, and results of past groundwater monitoring that have been conducted. Please refer to section O. and P. in the Conditional Use Permit Application. Ground water monitoring has not been conducted in the past at this facility. Although a comment letter was not received for this site from the Carnelian - Marine - St. Croix Watershed District, responses to comments they had in their Bracht Bros., review are provided. 1) The submittal information received on January 18, 2008, is acceptable as far as general information on proposed operations and narrative requirements but lacks the specific information and detailed plans and design information the district will need to evaluate the project. a. Provide a wetland buffer plan. Vegetation will be maintained for a minimum of twenty feet between wetland and mining limits in order to provide a buffer to the wetland. Please refer to the Drainage and Erosion Control Plan. b. Provide detailed drainage plan and supporting computations documenting that rates and volumes discharged off site are not increased over pre- settlement conditions; for the interim mining phases and final site at completion of mining activity. To estimate pre-settlement conditions district will accept assumption of existing conditions topography, 'A"soils or mapped Stormwater Management Calculations Dresel Contracting, Inc. 3/2008 New Scandia, MN NM existing soil types. A native prairie land cover should be assumed for the areas that are currently being mined. Drainage plan subwatershed maps and computations need to include off-site areas that drain to the property. Please refer to the following stormwater management calculations, exhibits and HydroCAD modeling for a detailed drainage plan. Assumptions are described in this summary and throughout the report. c. Design information for water quality features needs to be provided. The site utilizes internal low areas to collect stormwater within the floor of the mining area. The locations of these low areas change as mining progresses. The basins are not designed to any standard because stormwater does not discharge off site. Please also refer to the SWPPPP for the site. d. District will expect drainage plan and models to be of sufficient detail to also evaluate expected impact to on site wetlands. Please refer to the following stormwater management calculations, exhibits and HydroCAD modeling. e. Drainage and erosion control plans need to include construction details for installation of stormwater management and erosion control practices (proposed BMP's). Design information on size of proposed practices and when they will be placed and how they will be maintained will also be required. Please refer to the Drainage and Erosion Control Plan. Currently screening berms are in place. Also, as mining progresses through silt fence will be added per the Drainage and Erosion Control Plan. Please also refer to the SWPPP. f Provide copies of the groundwater monitoring plan (include reports on past monitoring activities under previous County permit), spill response plan and emergency response plan. Please refer to section O. and P. in the Conditional Use Permit Application. Also, please refer to section 14, Contingency Response Plan. Ground water monitoring has not been conducted at this site. Stormwater Management Calculations STORM WATER POLLUTION PREVENTION PLAN FOR DRESEL CONTRACTING, INC. Scandia, Minnesota Permit number MNG490000 A. GENERAL This plan has been prepared in compliance with the provisions contained within the National Pollutant Discharge Elimination System (NPDES) and State Disposal System (SDS) Permit MN G490000 for Construction Sand and Gravel, Rock Quarrying and Hot Mix Asphalt Production Facilities. The subject site is a sand and gravel mining operation. This plan shall remain on-site, or if there is no suitable on-site storage location, may be maintained at a readily available off-site location, and will not be submitted to the Minnesota Pollution Control Agency unless requested. B. Site Map A site map is attached which illustrates the following items: Township Range and Section, topography, wetlands, streams, ditches, lakes and other nearby surface waters, identification of DNR designated trout streams, outstanding resource value waters (OVRW's) and the Clean Water Act, Impaired Waters within one mile of the site, water wells, surface water supply intakes, pit dewatering points, direction of stormwater runoff from the site and name of surface water that receives any surface discharge. The plan also illustrates significant materials storage areas. There are no impervious surfaces within the mining area. There are no OVRW's or DNR designated trout streams within 1 mile of the site. An Impaired Water, Bone Lake, is located 4600 feet northeast of the site. Most stormwater drains internally to low points within the site's mining limits. A small area within the northeast mining limit boundary drains to low points outside of the mining limits, but still within site boundaries or immediately adjacent to the site. A small area in the western portion of the site drains to the wetland located partially onsite to the west-southwest. C. POTENTIAL SOURCES OF POLLUTANTS The following are potential sources of contamination of storm water at the site. 1. Excavation areas: Sediment picked up in runoff contacting areas stripped in preparation of mining activity as well as exposed mining faces and pit floor. 2. Portable crushing and screening equipment operate periodically at the site. Leaks from equipment used at the site have the potential to contaminate stormwater. 3. Materials Storage areas. There are no chemicals or explosives stored on-site. Topsoil, overburden, natural aggregates and recycled asphalt and concrete are significant materials stored on- site. 4. Conveyors are not operated at this site. 5. Material loading occurs on the pit floor directly from the active face or from processed aggregate stockpiles located on the pit floor. 6. Roads and vehicle parking: All internal haul roads are gravel surfaced. There are no designated parking areas. 7. Fuel storage and fueling: All storage tanks are above ground and have secondary containment. - 8. Vehicle and equipment maintenance activities are performed on- site. No engine degreasing is performed on-site. 9. Equipment washing is not performed on site. 10. Buildings: There are no buildings associated with the mining operation. 11. An asphalt plant is not associated with this operation. Therefore there is no asphalt storage, truck box lubrication or cleaning, wet scrubber discharge or sediment and sludge storage from asphalt plant operations occurring at this site. D. PRACTICES TO REDUCE POLLUTANTS IN STORM WATER DISCHARGES FROM THE SITE Perimeter controls Best Management Practices (BMPs) implemented at the site which control stormwater and prevent it from discharging untreated from the site include silt fence and perimeter diversion berms where needed. - BMPs implemented at the site which will help to stabilize the site include seeding and mulching of areas that have been graded to final reclamation elevations. BMPs to prevent stormwater from contact with significant materials include the grading of the pit floor to direct runoff from the floor of the mining operation away from significant materials. In addition to these specific management practices used to reduce and minimize the potential for sediment discharge off-site, more general best management practices are used throughout the site such as erosion control fencing around sensitive areas, containment of aggregate stockpiles within recessed portions of the site, routine maintenance of equipment and employee training in the proper use and handling of equipment and materials handled on-site. The permittee will, on at least an annual basis, review the current EPA approved list of impaired waters and the TMDLs to determine if and to what extent the site's Pollution Prevention Plan must address these impairments and TMDLs. E. NON-STORM WATER DISCHARGES There are no pit dewatering discharges or other non stormwater discharges from the site. F.

Documentation of any changes made to the Plan. H. FINAL STABILIZATION AND CLOSURE: Dresel Contracting, Inc. will be released from the inspection, recording and reporting requirements of this permit for this site when they no longer conduct the activities authorized by this permit and certify on the Annual Report/ Site Inventory Form that: a. There is no stormwater runoff and/or pit dewatering from the site; or b. The Permittee certifies that a new owner or operator has assumed responsibility for the site; or c. The site closure achieves final stabilization. Site closure must achieve final stabilization as follows: a. The drainageways that leave the site are stabilized to prevent erosion with riprap or other protective material. b. The soil disturbing activities at the site are completed and all soils are stabilized by a uniform perennial vegetative cover with a density of 70 percent over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions. c. The drainage ditches constructed to drain water from the site are stabilized to preclude erosion. r d. The temporary, synthetic, and structural erosion prevention and sediment BMPs (such as silt fence) are removed. e. The Permittee cleans out all sediment from conveyances and from temporary sedimentation basins that are to be used as permanent water quality management basins; sediment must be stabilized to prevent it from being washed back into the basin, conveyances or drainage-ways discharging off-site or to surface waters. The cleanout of permanent basins must be sufficient to return the basin to design capacity. f. The Permittee installs permanent stormwater treatment for new impervious surfaces created as a result of the activities covered by this permit. The permanent stormwater treatment must be designed for 0.5 inches of runoff from all created impervious surfaces. g. Other BMPs as necessary are implemented so as to prevent erosion from the site excavation areas and stockpiles that have been used by the Permittee. z ,, o z IIIII )111111 o? i t 1 1 { l d d w z e t t (/) �' IJ o x Fob 2 I t a e�6 MeW o �Z 3 :i�atcc�. t p. 3 g n a o h a .8 I - 3 if Iy r - z� Blfhii . . o c< $s A N .2,Ia 3 2 2 b 2 w 3 ro.J w; . . d 4 ,.: f. yxSS pp q .� TTT1 Y oigT ;Via I NUa i_ p�oy C n °o °,E.e °_ p - _go _°E` - �8 s "nooa 2°a a «° a` s c .. e o2, 0° jo oo«E-gzottgt? _'62^ ,,E.8 8 ,`o E p j15. o0 9 '- -Eli200 ° r 'Eg Ep gt =...--sue (') G p vE °- __oo-' U pOp Lu p0 ,iii---- L.p.C= o n 3 E-.con .y10yyW1111 1✓"�� �� I o E E ..°y c m a:u u I, ;' \--4,______IT Iratt , : 1,z-litti vg-t&IL. \ //',`�/q 1 ji �l /ram •ja i � Sv22 II- °n`olAi ap, ih o t -- ,---11 0 i ft, rib'ra - (,6 "?? --/ T\i 4 , --,Lik a I.§ - '11 / ‘77 f"4-itio 1 ,,Avki /\' \ i 1 '/K irr---- --,-- -, ,,A0lif 7 l' ,- g t to ..6 // I /) / \ /j.'f /// 8”, o c c o- ,y 2 L. ° ° o j ✓� ooti i Ili - ; giao�E of Io 7 1 r_:;_/40: '7////////ji------ '•1 4 ____,_!! 0%0,...,4E: ,!,- t ! 7 ai- • JEe o ° E E° o c ° F !li tii! i ic: 1 i F I .`'- -} / .r- 1 / ..... i \ i a E '' ; Po 0,0e gar.-' s.14,, SiftWON,Atii fTh/i,®� t 55 'il- gnR1.4'4SYd __,-- '- ; ; : o o a,o`o"° -c Y '`p _ ygalls c o o p / , y :4 s i'� . - '1. ;' 2" o p 3 n'.o p a o o y Y o u - }bV . \.v ) 1 rc> EOM of= Eg oW a'ao°c°E`oa <'yn: i 3 3E .o. - H n r h November 2007 Updated with Submittals through Mayl,2008 DRESEL CONTRACTING, INC.

SAND AND GRAVEL MINING OPERATION CITY OF SCANDIA WASHINGTON COUNTY, MINNESOTA I. INTRODUCTION The following permit application is submitted on behalf of Dresel Contracting, Inc. (Dresel) in compliance with the City of Scandia's Ordinance No. 103 and Chapter 4 of the Development Code: Mining and Related Activities Regulations adopted by the City of Scandia on August 28, 2007. Dresel operates a gravel mining and processing operation within the City of Scandia. The site has been actively mined since the late 1960's. Prior to the incorporation of Scandia in 2006, New Scandia Township and Washington County were the permitting authorities. Permitted activities include the removal and processing of aggregate and the recycling of concrete and asphalt. The operation is located on two parcels of property. The western parcel encompasses 40 acres, of which approximately 31 acres will be mined, and is owned by Dresel. The eastern parcel encompasses 17 acres, of which approximately 5 acres will be mined. The eastern parcel is owned by Roth and leased by Dresel. The entire operation therefore is situated on 57 acres, of which 36 acres is included within the active mining limits. II.

A narrative outlining the type of material to be excavated, mode of operation, estimate of amount of material to be removed, plans for blasting, estimated time to complete the removal, and other pertinent information to explain the request in detail: The mining operation includes removal of overburden, excavation of sand and gravel, crushing, washing, screening, stockpiling, recycling of concrete and asphalt products, and reclamation activities. The site usually operates on a seasonal basis from approximately mid April to mid November depending upon weather conditions. Plans included in this submittal illustrate the current status of mining activity, the locations of operations, phasing, proposed reclamation grades and potential restoration. Overburden is removed from areas to be mined and is stockpiled on site and later used for reclamation of completed phases. Aggregate is excavated using front end loaders. Processing consists of crushing, screening, and stockpiling. Recycling of concrete and asphalt occurs at the site and also consists of crushing, screening and stockpiling. The final product is loaded on trucks using front end loaders and the product is delivered to projects throughout the area An estimated 750,000 - 1,000,000 cubic yards (cy) of aggregate reserves remain at the site. Annual production is quite variable. The material is used to supply local projects. Based on previous site activity, annual production at the site varies from 0-100,000 cy. The life of the facility is completely dependent upon future market demand. Blasting does not occur at this site. 5.

Wells should include private/agriculture, industrial, municipal wells within 1/2 mile radius of the mine. Adjacent land features, platted subdivision lots, metes and bounds parcels, and homes within 1/4 mile of the property are indicated on the Existing Conditions Plan, C1. All wells within 1/2 mile radius of the facility, which are on file at the Minnesota Department of Health's County Well Index, are indicated on Figure 2. G. A minimum of 1 cross section for every 1000 feet running north/south and east/west, showing the extent of overburden, extent of sand and gravel deposits, the groundwater level, and any evidence of the groundwater level in the past. A series of two north-south and two east-west cross sections are included as Sheets C5-C6. These cross sections depict the existing elevation, overburden, final elevations, extent of deposit, and the elevation of the groundwater. Soil borings were completed as part of the original permitting process. Soil boring data was used to develop the site cross-sections. H. All processing areas and boundaries shown to scale. Processing areas are identified on the Site Plan, C2 All access roads within the site to processing and mining areas shown to scale: Access Roads to the processing and mining areas are indicated on the Site Plan, C2. J. Sequences or phases of operation showing approximate areas involved shown to scale and serially numbered with a description of each. There are essentially four main phases of mining remaining at the site. Two of the remaining phases may be mined concurrently. The sequence of operations showing the approximate areas involved and the various phases of the operation are indicated on the Phasing Plan, C4. K. Location of screening berms shown to scale, and notes provided indicating when they will be used as reclamation material. In the same manner overburden storage areas must be identified and noted. The location of screening berms and overburden stockpile areas are indicated on the Site Plan, C2. L. Fences and gates and their type or construction described and illustrated: Fences and gates are indicated on the Site Plan, C2. Three strand wire fence surrounds the site. Locking metal gates are located at the site entrance. M. Proposed location of principal service or processing buildings or enclosures as well as locations of settling basins and process water ponds: There are no buildings or structures on the site. Stormwater collects at low areas within the pit floor and infiltrates. N. Existing site drainage features and flow directions indicated. A plan for handling surface drainage during operation and after final reclamation, consistent with local surface water management plans. Surface water will be managed during active mining in accordance with the site's NPDES Stormwater Pollution Prevention Plan (SWPPP) and consistent with local surface water management plans. The SWPPP includes a number of best management practices (BMPs) which are incorporated into daily site operations. The BMPs have been designed and implemented to avoid untreated stormwater discharge from the site, minimize potential for erosion and sedimentation throughout the operation of the site and provide for site stabilization at the conclusion of mining activity. Erosion and sedimentation control practices used on site during active mining include silt fence, vegetated screening berms, wetland buffers and dust control. Screening berms around the perimeter of mining area are vegetated to reduce erosion and to help contain fugitive dust. Stormwater contacting exposed areas drains internally. A vegetative buffer strip is preserved around the wetland basin located west of the active mining area. The buffer strip filters runoff and reduces the potential for sedimentation to occur within the wetland basin. Erosion and sedimentation control practices after final reclamation include achieving permanent stabilization of the site through proper reclamation design standards. After mining is completed, reclamation will be performed to restore the site to a stable condition, minimize the potential for erosion and allow for future development of the land. Reclamation will involve slope stabilization, seeding and mulching. The Reclamation Plan, C4, indicates proposed site elevations upon completion of restoration. Slope stabilization will be accomplished by backfilling and grading the side slopes to a maximum of 4:1. A minimum of four inches of loamy soils, suitable as topsoil, will be placed on the graded slopes. After topsoil has been placed, the slopes will be seeded and mulched to establish vegetation. Reclaimed areas will be planted with a mix of native trees, shrubs, grasses, flowers and groundcover. O. A plan for groundwater quality protection to include a minimum of three soil borings showing depth to groundwater. Three soil borings were drilled in conjunction with past permitting work. The locations of the soil borings are indicated on the site plan, C2. The soil borings identified the water table at an average elevation of 919 feet above mean sea level beneath the site. The mining operation is located in an area characterized by the prevalence of very granular, permeable and non-reactive soils with very low filtering capacity typical of sand and gravel deposits. If contaminants are introduced into the soil column, groundwater may be impacted within a very short time frame. There are a number of site BMPs and technologies available that are discussed below which eliminate or reduce the potential of introduction of contaminant sources into the soils. Groundwater Protection Plan • Limited equipment maintenance is performed on-site and follows company spill prevention policies. • A service truck comes to the site to perform routine maintenance. All used lubricating oil is collected by facility personnel and hauled off-site to a central collection point (waste oil is not classified as hazardous waste). The service truck carries a spill containment kit. • All storage tanks are above ground and have secondary containment. • Topping off of tanks during refueling of any kind is not allowed. • Availability of spill cleanup equipment on-site including equipment to excavate and remove impacted soils in an expedited fashion. Measures to protect groundwater quality will be incorporated into final site design once final development has been determined. These will involve a variety of best management practices, including stormwater treatment, erosion control and vegetative filter strips. P. All mining operations must install one monitoring well. If the proposed mining operation will appropriate groundwater for use in mining operations, the operator shall install not less than one monitoring well down gradient of the mining operation. If the proposed mining operation will include mining into the groundwater table, not less than two monitoring wells shall be installed one up- gradient and one down-gradient of the mine. Groundwater Monitoring Plan Groundwater monitoring will be conducted on an annual basis at the site. Currently there are no monitoring wells on the site. One monitoring well will be drilled on the north end of the property and will function as a down gradient well. This well may also serve as Tiller Corporation's upgradient well. The well will be monitored for Diesel Range Organics (DRO) on an annual basis. Monitoring results will be submitted to the City of Scandia. Q. If lighting is proposed, a plan for lighting the area must be provided. The plan must comply with all City ordinances pertaining to lighting. There is no lighting proposed at the site. R. Reclamation Plan in conformance with Section 8. The Mining and Reclamation Plan, Sheet C3 is a graphic representation of reclamation activities. • Intent: The intent of reclamation activities covered in this section is to restore the site to a stable condition, minimize the potential for erosion and allow for future development of the land. • Methods and processes of reclamation: Reclamation will involve slope stabilization, seeding and mulching. Slope stabilization will be accomplished by backfilling and grading the side slopes to a maximum of 4:1. A minimum of four inches of loamy soils, suitable as topsoil, will be placed on the graded slopes. After topsoil has been placed, the slopes will be seeded and mulched to establish vegetation. • Initial condition of mining site: The site has been a mining operation for many years. • Limits of various operational areas: The operational areas are indicated on the Site Plan, Sheet C2. • Phasing and timing of operations and reclamation including areas to be stripped of overburden. Phasing of mining operations is included on the Phasing Plan, Sheet C4. Phase 1-A will be mined in conjunction with Tiller Corporation to accommodate the removal of the common mining border. Phase 1-B may be mined concurrently with 1-A Some reclamation activity has been completed. These areas are illustrated on the Site Plan, Sheet 2. Reclamation of sideslopes will continue as mining progresses around the perimeter of the excavation limits. • Final condition of the site, including proposed contours and landscaping: The Mining and Reclamation Plan, Sheet C3, indicates proposed site elevations upon completion of restoration. • Relation of final site condition to adjoining land forms and drainage features within '/ mile. Reclamation of the site will result in open space with wooded areas and an isolated wetland basin in the western portion of the site. • Relation of reclaimed site to planned or established uses of surrounding land: The land is designated general rural/agriculture with 4/40 densities. Surrounding land use is similarly guided. Established land uses are agricultural and rural residential in nature. • A plan for maintenance of reclaimed area: See Mining and Reclamation Plan, Sheet C4. • A detailed cost estimate of reclamation and maintenance: Reclamation costs for the area currently opened to mining (essentially entire site) are outlined below: Finish grading of disturbed area; 36 acres: 36 acres at $1,000/acre $36,000 Placement of 4" topsoil from on-site stockpiles; 36 acres: 19,360 cy at $ 1.00/cy $19,360 Seeding and Mulching 36 acres at $600/acre $21,600 Total reclamation costs; $76,960 Reclamation will proceed concurrently with mining operations. Reclamation activities which take place during the past mining season as well as reclamation activities planned for the subsequent mining season will be discussed in each annual report. Reclamation standards as included in Ordinance No. 103 Section 8.3-8.8 will be followed. S. If blasting is proposed as part of the mining operations, the operator must indicate frequency, timing, size, duration and develop a blasting plan: Blasting is not performed at this site. T. A description of any processing operations including washing crushing, recycling and bituminous plants and concrete ready-mix plants. Aggregate is excavated using front end loaders. Processing at the site generally includes crushing, screening, and stockpiling of aggregate, and the recycling of concrete and asphalt by crushing, screening and stockpiling. III. OPERATING CONDITIONS 1. Setbacks: Mining, stockpiling or land disturbance activities, with the exception of berming and visual screening, will be setback 50 feet from an adjoining property line, 200 feet from an occupied structure, 100 feet from any contiguous property subdivided into residential lots of 5 acres or less, and 100 feet from any road right-of-way. Reclamation activity may occur within 50' of the road right-of-way. As indicated in the plan set, the setback along the common mining boundary to the north is 0'. 2. Fencing: The entire site is fenced with 3 strand wire fencing except where prohibited due to topography, woods and wetlands. There is a locking metal gate at the entrances to the site. 3. Hours of operation: The site is operated from 7:00 a.m. to 7:00 p.m. Monday through Friday except holidays. Extended hours may be required periodically for situations such as emergencies, accelerated work schedules or weather delays. If operations are required beyond the 7:00 a.m. to 7:00 p.m. hours, or on Saturdays, Sundays or holidays, prior permission will be obtained from the City of Scandia in accordance with procedures set forth in Ordinance No. 103. 4. Screening: The site is operated in a manner to minimize the visual impact of the extraction and processing area on surrounding properties. There is buffer area to the west and a screening berm along 218th Street N. Processing and stockpiling operations are conducted in recessed portions of the site to minimize visibility. The location of the screening berm is indicated on the Site Plan, Sheet C2. 5. Dust control: Dust is generated by crushing and screening equipment, excavation and loading equipment, and vehicular movement. Processing areas are located at elevations lower than the surrounding terrain in order to minimize windborne dust leaving the site. Screening berms and perimeter vegetation also minimize dust from leaving the site. 6. Noise: Noise is generated from processing activities, loading processes, and vehicular movement. Noise is minimized by conducting processing activities within the interior of the site at elevations lower than the surrounding lands. All activities are conducted so as to be in accordance with all Federal, State and County noise standards. 7. Depth of excavation: Excavation is conducted to a maximum depth of approximately 920 feet above mean sea level. Some backfilling may be required to obtain final restoration grades. 8. Site clearance: Trees, stumps, roots and other vegetative material removed during site clearance or other activities will be disposed of by logging and/or chipping. Logged material will be used for lumber or firewood. Chipped material will be used as mulch, bio-fuel at approved facilities, erosion control devices or other approved utilizations. 9. Appearance/condition: All buildings, plants and equipment at the site will be maintained in a neat condition. Weeds and other unsightly or noxious vegetation shall be controlled as necessary to preserve the appearance of the reclaimed areas. 10. Sanitary Facilities: • Portable sanitary facilities are provided in the operating area. 11. Waste Disposal: Any waste generated from the operation shall be disposed of in accordance with Federal, State and County requirements. 12. Water Quality Monitoring: See Sections II. 0 and II. P. 13.

EREMMONS &OLIVIER RESOURCES MEMORANDUM Date: March 31, 2008 To: CMSCWD Board of Managers From: Lisa Tilman, P.E. and Dan Fabian, P.E. Re: Summary of Review and Recommendations for Permit App. No. 08-004 Dresel Contracting Mining Operation, Scandia RECOMMENDATIONS We recommend Managers authorize Administrator to approve and issue permit contingent on Applicant addressing following comments (Primary issues are items 3 and 4), to satisfaction of District Engineer: Summary of comments to be addressed prior to permit issuance: 1. For the required review fees a deposit of$2,000.00 has been received. Applicant is responsible for replenishing this deposit if it appears it will be insufficient to cover District review costs. The estimated completion date for this project is 2025 +/-. The District's standard permit length is 1-year. Managers will need to determine duration District permit will be valid before it will need to be renewed. If permit length is longer than 1-year a minimum annual status update from applicant and site visit should be coordinated with Scandia CUP and issuance of Annual Operators Permit. Managers will also need to establish method to re-coup costs for annual reviews. 2. District surety still needs to be provided. The City of Scandia requires a surety as part of its Mining Ordinance CUP and Annual Mine Operators Permit. Managers should consult with City to see if an agreement can be made that District would not need to require a separate additional surety. Perhaps requiring the applicant to maintain a cash deposit with the District of some amount as part of the permit fee requirement would be acceptable. This would ensure that District would recoup on-going review fees, while any major issues could perhaps be addressed through coordination with the City's permit enforcement process. 3. The proposed conditions site calls for excavated within 3-feet of the groundwater table. As far as we know this was not previously permitted for this site. Excavation into the groundwater is not allowed per current District requirements. Revise proposed conditions mining plan to raise pit bottom elevations to at least 3-ft above the groundwater elevation (currently identified at 919.0-ft). This area of the proposed final grade of the pit appears to be an extension of the adjacent the Tiller Corp. proposed groundwater lake. The Managers will need to provide direction to staff on how to best handle this issue. The Tiller Corp. Permit submittal is currently incomplete and review is on hold until application is Page 2 3/31/08 Dresel Contracting Mining Operation Review completed. Assuming the Tiller Corp. Permit is eventually approved, and that the EAW prepared for that project included the work in the Dresel Pit, and then a permit revision for mining into the groundwater could be requested at that time. 4. The proposed total discharge volume offsite for the 2-year and 10-yr events exceed the total pre-settlement discharge volume offsite. The additional discharge is to the north and is directed to a large groundwater"lake"to be constructed with the reclaimed site condition on the Tiller Corporation property. The increase in runoff volume offsite also likely indicates an increase in phosphorus load offsite. The increased offsite drainage will be directed to a basin to be constructed with the reclaimed site condition on the Tiller Corporation property. Provide written, legal documentation from the landowner of the Tiller Corporation property that use of the property for stormwater management in the reclaimed condition is allowed. 5. The submitted information does not allow a clear evaluation of the potential to drain the two wetlands located adjacent to active and proposed mining operations. Provide field delineation and report for the two wetlands adjacent to the pit. The westerly wetland is identified as a Category 2 wetland under current district requirements and has a 50-ft buffer requirement. Maintain an undisturbed buffer area of at least 50-ft for both of these wetlands until wetlands are delineated and potential impacts and requirements are determined. (Note: the delineation requirement can be included as a permit stipulation to be completed this spring). 6. Include in plans procedures for loosing of soil to restore Soil permeability prior to final planting and site restoration. Concern is that under the reclaimed condition if B soils are used as fill, (as currently proposed)and they are heavily compacted during placement, soils will function like C soils and runoff will increase. 7. Include measures to avoid tracking of sediment offsite through vehicle traffic. GENERAL COMMENTS AND BACKGROUND INFORMATION The Dresel Contracting Mining Operation is located east of Lofton Avenue and north of 218th Street in the City of Scandia, MN (see Figure 1 for location map). The proposed project entails the continuation of gravel mining and processing activities on a 57 acre lot. The project includes crushing and washing of gravel and recycling of concrete and asphalt, but does not include an asphalt plant or pit dewatering. The project will disturb a total of 35.5 acres through mining to an elevation of 918 ft.; 31 acres of the site have been disturbed through past mining operations. The groundwater elevation is estimated to be about 919 ft. based on soil borings taken in the past (to date, soil boring information has not submitted to the District). Proposed plans call for excavation within 3-feet the groundwater which is contrary to the requirements of current District rules. The site does not drain directly to an identified groundwater-dependent natural resource; however the adjacent Tiller Corp. Mining Operation will be creating a groundwater lake. Future proposed development of area after mining operation is complete will need to take that into account. Page 3 3/31/08 Dresel Contracting Mining Operation Review Permit application is for completion of planned mining activities through complete restoration of vegetation for entire site. Any further proposed development of site following completion of mining activities will require a new permit application submittal and will need to meet the district permit requirements applicable at the time of submittal. The Carnelian Marine St. Croix Watershed District (District) initially provided review comments to Scandia on this project that primarily pertained to the completeness of information received by City to meet District permit submittal requirements, in our letter dated January 25, 2008. All remaining materials, needed for a complete District Permit Application for this project, were received on March 24, 2008 (review was started on partial submittal received on March 10, 2008). The District also provided input to Scandia during development of their Mining Ordinance in 2007.

No.: 14059.001 From: Sherri Buss, R.L.A. Routing: Date: May 2, 2008 SUBJECT: Tiller Corporation - Conditional Use Permit Application for a Mining and Processing Operation MEETING DATE: May 6, 2008 LOCATION: Sections 7 and 8, Township 32 North, Range 20 West APPLICANT: Tiller Corporation 7200 Hemlock Lane, Suite 200 P.O. Box 1480 Maple Grove, MN 553 1 1-6480 120-DAY PERIOD: June 12, 2008 ZONING: Agricultural District, Shoreland Overlay District ITEMS REVIEWED: Application, Plans BRIEF DESCRIPTION OF THE REQUEST: The Application is for a new Conditional Use Permit (CUP) for an existing sand and gravel mining operation located on Manning Avenue near 225th Street in Scandia. The site has been actively mined since 1966, and has operated under a previous CUP granted by Washington County, when the County exercised land use authority within New Scandia Township. Permitted activities included the mining and processing of aggregate, the production of hot-mix asphalt, and the recycling of concrete and asphalt products. The site includes several parcels. The total site area is 395 acres, and 155 of these are proposed for mining and reclamation. An Employee Owned Company Promoting Affirmative Action and Equal Opportunity Scandia Planning Commission Page 2 May 2, 2008 Tiller Corporation, CUP for Mining Mining Operations The mining operation includes removal of overburden, excavation of sand and gravel, crushing, washing, screening, stockpiling of sand and gravel; recycling of concrete and asphalt products; the production of hot- mix asphalt and reclamation activities. The overburden is removed from areas to be mined, and stockpiled on the site for use in reclamation activities. The Applicant indicates that the site usually operates on a seasonal basis from mid-April to mid-November, depending on weather conditions. The aggregate is excavated above groundwater using front-end loaders. A dragline or excavator will be used to excavate material within the groundwater. Processing activities include crushing, screening, and stockpiling. The recycling of concrete and asphalt on the site also includes crushing, screening and stockpiling. Front-end loaders place the specified aggregates into cold feed bins. The aggregates are metered out onto a conveyor, which delivers the aggregate into a rotating drum, where they are blended, heated and dried. Heated asphalt cement and recycled asphalt are mixed with the heated aggregate and conveyed into insulated overhead silos. Trucks are loaded from the silos, and weighed. The final product is delivered to project sites throughout the area. The asphalt plant at the site is equipped with a baghouse air pollutant collection device, and operates under a Minnesota Pollution Control Agency(MPCA) Air Emissions Permit. Storage tanks at the site (for fuel and asphalt cement) are regulated by the MPCA. The main access route to and from the site are Manning Avenue (County Road 15) and Lofton Avenue (County Road 1). Both Manning and Lofton and are paved. The haul road from Manning Avenue is paved through the site to the hot-mix asphalt plant and loading area. The Applicant notes that blasting does not occur at the site. Phasing of Site Operations The Applicant indicates that there are three phases of mining remaining at the site. Mining will occur both above groundwater and into the groundwater in each of these phases. The Applicant indicates that due to the variable nature of the aggregate deposit, it is necessary to mine above and below the groundwater concurrently in order to obtain the proper blend of aggregates. Mining into the groundwater will occur for the first time under the new permit. This activity has been described in the previous mining plans for this site, and was evaluated in the Environmental Assessment Worksheets completed for the Tiller site in 1987 and 1999, but has not been implemented in previous mining phases. The Phasing Plan indicates that Phase 1 a and 1 b will occur throughout the central portion of the site. Phase 2 will expand the operation to the east, and Phase 3 will expand operations to the east again. An estimated 9 million cubic yards of aggregate reserves remain at the site. Annual production at the site is 300,000 to 400,000 cubic yards. The Applicant indicates that the life of the facility is estimated to be about 20 to 30 years, but is dependent on market demand. The phasing plan identifies four remaining phases: 1 a is Scandia Planning Commission Page 3 May 2, 2008 Tiller Corporation, CUP for Mining along the north boundary of the site and would be mined concurrently with lb at the south along the entry drive; phase 2 is in the center of the site, and phase 3 is in the eastern 1/3 of the site. Groundwater and Surface Water Maps included in the application indicate that the water table is located at an average elevation of approximately 920 feet. The bottom depth of the lake proposed to be created as a part of site reclamation is mapped at approximately 870 feet. The Applicant describes a variety of measures instituted at the site to control potential spills. A Spill Prevention Control and Counter Measures Plan has been prepared for the site, including reporting requirements that meet state statutes and regulations. Groundwater monitoring is conducted on an annual basis at the three wells on the site. The monitoring well network will be expanded prior to mining into the groundwater. Three additional monitoring wells will be installed before mining activity begins to monitor groundwater quantity and quality. The wells will be used to record water levels twice a year during the spring and fall. The wells will also help to define the regional water table near German Lake, and to monitor fluctuations of groundwater levels associated with mining activity. Monitoring results will be submitted to the City of Scandia. The Applicant indicates that surface water will be managed in accordance with the site's NPDES Stormwater Pollution Prevention Plan (SWPPP), and consistent with local watershed management plans. The SWPPP includes a variety of Best Management Practices (BMP's) to avoid discharge of untreated water from the site, minimize erosion and sedimentation, and stabilize the site at the conclusion of mining activity. Stormwater collects on the floor of the mining operation to handle internal drainage. It is pumped when needed to a second upland sedimentation basin for additional treatment. If this second basin overflows, the water enters an infiltration basin area prior to entering a wetland on the site. There are no permanent ponds for washing operations. Temporary ponds are located near the washing plant. Sediment from the ponds is used in reclamation activities. Berms and Screening The site has some existing berms at the site entry from Lofton Avenue and on the northern boundary. It is also screened by wooded areas on the west and southeast portions of the site. No additional screening is proposed. Reclamation Plan The reclamation plan includes slope stabilization, seeding and mulching. It also includes creation of a 50- acre lake in the central portion of the site. Environmental Review Completed on the Site Two Environmental Assessment Worksheets (EAWs) have been completed for this mining facility. The first was completed in 1987 as a part of the initial permitting process. The second EAW was completed in 1999 Scandia Planning Commission Page 4 May 2, 2008 Tiller Corporation, CUP for Mining for a proposed expansion of the facility. At that time, the mining limits were revised by adding areas to be mined on the east side of the property, and removing areas that were more environmentally sensitive on the western side of the property from the mining limits. The scope of operations and mining limits proposed in the current permit application to the City are consistent with the scope of the operations and mining limits reviewed in the 1999 EAW. The site is exempt from further environmental review, unless the proposed mining and related operations expand beyond those evaluated in the 1999 EAW. Both EAWs included evaluation of environmental impacts that could result from mining into the groundwater to the degree proposed in this application, and creation of a lake as a part of the reclamation plan. During the EAW process, Washington County hired Barr Engineering Company to perform a hydrogeologic investigation of the impacts of mining into the groundwater, and the potential impacts of the artificial lake on German Lake. The report determined that the impacts of the withdrawal of gravel from below the water table would have a negligible long-term effect on the water table and the level of German Lake. EVALUATION OF THE REQUEST The Applicant is requesting a Conditional Use Permit for a mining operation. The proposed use is governed by the City's Ordinance No. 103, Mining and Related Activities Regulations. This review evaluates the request for a CUP based on the City's Ordinance and materials submitted by the Applicant. Groundwater Issues LBG conducted an initial review of CUP Application and related information in March 2008. From this review process, LBG identified specific portions of the CUP Application that required additional information and/or clarification on ground-water related issues. LBG prepared a series of questions that outlined these data gaps, which were submitted to Sunde Engineering through TKDA. Sunde responded in writing on April 15, 2008. LBG has reviewed this recent information and found that it sufficiently addressed the questions with the exception of the items presented in the general comments in LBG's letter dated 4/28/08 (attached). General Comments 1) Depth to Ground Water and Flow Directions: The three on-site piezometers will provide sufficient information to determine depths to ground water, ground-water elevations, and flow direction of the water table aquifer across the site. Current data shows ground water in the water table aquifer flows to the northwest. The addition of the upgradient well proposed for the Dresel site and the proposed downgradient well on the Tiller site will better characterize these conditions. 2) Hydraulic Connection to German Lake: LBG has reviewed the available information from Barr Engineering, Emmons & Olivier Resources, and Sunde in regards to German Lake and the potential impact to this lake as a result of mining below the water table. LBG agrees with the conclusions presented in these documents that withdrawal of gravel below the water table will have a negligible long-term effect on the water table and German Lake. This conclusion is based on the hydrogeology of German Lake and the surrounding area. This lake and other shallow wetlands in the area are Scandia Planning Commission Page 5 May 2, 2008 Tiller Corporation, CUP for Mining created by surface water runoff and shallow ground water that remain suspended or perched above the regional water table aquifer. Clay layers above the water are typically responsible for creating these perched features, which are not hydraulically connected to underlying water table aquifer. Tiller has proposed a monitoring plan to identify potential impacts to the water table and German Lake. 3) EAW: LBG has reviewed the ground-water sections of the EAWs that pertain to ground water, the other information provided to date, and the proposed ring plan that will be implemented as part of the CUP Application. With respect to ground-water, LBG agrees with the 1987 and 1999 EAWs regulatory findings and the negative declarations for an EIS. 4) Monitoring Needed: The CUP Application states that a diesel range organics (DRO) will be monitored in the existing and proposed wells. However, DRO does not identify the full gasoline range organics (GRO) spectrum. If gasoline is to be stored on site, then GRO and benzene should be added to the list of analytical methods. Recommendations Given the general comments above and from our review of the CUP Application and subsequent information provided by Sunde Engineering, LBG has the following recommendations for the Tiller site: • At this time, LBG does not see a need for Tiller to install more wells in the sand and gravel other than those already proposed. The existing and proposed monitoring well network appears to be sufficient and will characterize the depth to ground water and flow direction across the site in the water table aquifer. • LBG recommends that Tiller keep records of when the Production well is pumping. • Water-level measurements should be collected monthly for the first year and quarterly thereafter to evaluate seasonal variation in water elevation and to evaluate potential hydraulic connection between the sand and gravel aquifer and German Lake. Monitoring frequency should be increased in wells closest to the area where mining occurs below the water table when mining into the water table. • LBG agrees that ground-water samples should be analyzed for DRO. However, if gasoline is to be stored on site, then GRO and benzene should be added to the list of analytical methods. • At this point, given the current well search data provided and the proposed on-site monitoring well network, LBG does not recommend further investigation and monitoring of off-site residential wells. The proposed monitoring well network appears to be sufficient to identify potential impacts that may migrate off site. Watershed District and WCD Review of Surface and Groundwater Issues The Carnelian-Marine-St. Croix Watershed District Engineers have recommended that the District Managers approve a Permit for Tiller Corporation Mining Operations, contingent on the Applicant addressing the Scandia Planning Commission Page 6 May 2, 2008 • Tiller Corporation, CUP for Mining comments of the satisfaction of the District Engineer. Washington Conservation District staff reviewed wetland issues on the site, and provided recommendations that are included in the conditions for the CUP. The Applicant is required to obtain a permit from the CMSCWD and Comfort Lake-Forest Lake Watershed District as a condition of the CUP. Traffic There are two accesses to the mining site; one from 223rd Street west of Lofton Avenue, and one from another roadway approximately at 223rd Street east of Manning Trail. From information provided by the applicant, the maximum truck traffic is 750 trucks per day including both production and asphalt activities. Additional data from the applicant predicts average daily truck traffic at 173 or 212 trucks per day depending upon the production. Another 30 trips per day are expected from employees. The majority(70%) of this traffic will be use the roadway to access Manning Avenue, with approximately 5% of that to and from the north and 95%to and from the south. A northbound right turn lane and southbound bypass lane are provided on Manning Avenue. A `trucks hauling' sign is also provided for vehicles approaching from the north. A review of reported crashes did not show any crashes in this area from 2000 to 2005. Manning Avenue has an existing average annual daily traffic(AADT) volume is 1,250 vehicles per day in this area. The other traffic to and from the site uses Lofton Avenue, with traffic approximately split between north and south. A single lane of approach for each direction is provided at the 223rd Street and Lofton Avenue intersection. There are no `trucks hauling' signs posted on Lofton Avenue. A sign on site at the intersection with Lofton Avenue does prohibit trucks from using 228th Street. The existing AADT volume is 2,150 vehicles per day. A review of reported crashes showed only one property damage crash at this intersection in the years 2000 to 2005. It is important to note that, depending upon where a project is located, the directional distribution can be altered significantly. However, since turn lanes are provided on Manning Avenue and the AADT is lower, the applicant is recommended to encourage most, if not all, trucks to use that access. • Posting `trucks hauling' signs for the northbound approach on Manning Avenue and both approaches on Lofton Avenue are also recommended. Supplemental distance signs should also be provided below these signs and the existing one to inform drivers of the approximate location of the access. • Without lighting in the area and given the number of residences surrounding the site, hours of operation are also important. Restricting trucks to daylight hours, one hour before sunrise and one hour after sunset, or some other type of daytime limit, would provide benefits to traffic safety as well as overnight traffic noise. Alternatively, providing street lighting at the Manning Avenue access, and potentially the Lofton Avenue access, would allow operation later into the night. • Since the access to Lofton Avenue restricts trucks using 228th Street, a similar sign should be posted for the Manning Avenue access. This would keep the truck traffic off the local roadway near the site. • Scandia Planning Commission Page 7 May 2, 2008 Tiller Corporation, CUP for Mining Reclamation Plans Purpose The Scandia Mining Ordinance requires mining operators to provide a reclamation plan as part of their Conditional Use Permit Application (Chapter 4, Section 8). The plan must include graphic representation and written text. The Ordinance defines Reclamation, Restoration, Rehabilitation as follows: "To renew land to a self-sustaining, long-term use which is compatible with contiguous land uses and which process shall include re-establishment of vegetation, soil stability and establishment of safe conditions appropriate to the intended use of the land in accordance with the City's Comprehensive Plan and Conditional Use Permit conditions allowing for excavation and/or processing on the site." The ordinance further defines elements that must be present in the plan (intent of reclamation or final use, phasing and timing of reclamation, final condition of the site, etc.)timing concurrent with mining operation, requirements for grading and filling including final slopes, drainage, cover and planting, topsoil and removal of structures. If a mining operation will result in "accumulation of substantial water areas after reclamation" additional requirements such as water depths, grades above land as well as bottoms of water bodies are identified. In order to assure that the conditions of the reclamation plan are being addressed,renewal of the Annual Operators Permit(AOP) will in part depend on progress toward reclamation made on a yearly basis. To ensure that reclamation does occur in accordance with the approved plan,"the applicants are required to provide to the City an Irrevocable Letter of Credit or other security satisfactory to the City in the amount determined by the City." (Chapter 4 Section 9.3) The Tiller Mining Site is designated as General Rural - Agriculture Area in the Scandia Comprehensive Plan. The Plan states: "The General Rural/Agriculture Area is envisioned as an area that will remain sparsely developed over the next 25 years."The Scandia Zoning Ordinance designates the Tiller mining area as A-4 Agriculture. The two primary land uses in AG districts are Agriculture and Single Family Residential. Agricultural Use is defined as "Land whose use is devoted to the production of horticulture and nursery stock, fruit of all kinds, vegetables, forage, grains,bees and apiary products and raising domestic farm animals."The overall density of residential units is limited to four units per 40 acres. The range of potential final uses is limited to agriculture(including open space) and single family residential at a density no greater than 4 units per 40 acres. If clustering (under the Open Space Conservation Subdivision provisions of the Zoning Ordinance) is proposed, a landowner may increase density slightly provided certain conditions are met. Evaluation of the Tiller Reclamation Plan The Tiller CUP mining application includes the following documents: 1) Conditional Use Permit Application to the City of Scandia for Mining and Related Activities, Reclamation Plan in Conformance with Section 8 2) Cl Existing Conditions (dated 1/8/08) 3) C2 Site Plan (dated 1/8/08) Scandia Planning Commission Page 8 May 2, 2008 Tiller Corporation, CUP for Mining 4) C3 Mining and Reclamation Plan (dated 4/21/08) 5) C3-A Reclamation Sequencing(dated 4/20/08) 6) C4 Phasing Plan (dated 1/8/08) 7) C10 Concept Ultimate Use Plan (dated 4/17/08) 8) Letter to Sherri Buss from Kristen Pauly(dated 4/23/08) The Tiller reclamation plan submitted as part of the CUP application addresses the ten points listed in the ordinance with graphic and text submittals (Section 8.1). The reclamation plan states the purpose of reclamation activities is to "restore the site to a stable condition, minimize the potential for erosion and allow for future development of the site." The plan with revisions on updated plans describes the methods and process of reclamation, including prescribed seed mixtures for long-term soil/slope stabilization. It addresses phasing of operations and reclamation and shows final condition of the site. It includes a detailed description of the reclamation costs, which are estimated at $205,227 in 2008 dollars. The ordinance states that reclamation is to proceed concurrently and proportional to actual mining operations. Although much of the mining area has been opened up, the reclamation plan does not propose a reclamation schedule. The Reclamation Plan states that"reclamation will proceed concurrently with mining operations. Reclamation activities which take place during the past mining season as well as reclamation activities planned for the subsequent mining season will be discussed in each annual report." The Reclamation Plan includes a Reclamation Sequencing Plan (C3-A). This graphic shows the area already reclaimed on the northwest side of the mining area. It proceeds counter-clockwise from Reclamation Area 1 through Reclamation Area 6. The plan notes state that"this plan represents the general progression of reclamation. As mining is completed along the perimeter of the mining limits, slopes will be backfilled and stabilized with vegetation. Final reclamation will involve the removal of screening berms and areas that have been previously stabilized may be reworked to achieve final restoration grades and/or ultimate development grades. Because of the need to establish a large enough floor area for stockpiling and processing as well as a large enough area for dragline operations, it is not possible to reclaim an equivalent number of acres for every new acre that is opened to mining." The City will need to establish some timeline associated with the reclamation stages in order to form the basis for the AOP. The ordinance lays out requirements for excavations resulting in the accumulation of substantial water areas after reclamation. The proposed depth of the lake is proposed to be between 46 and 26 feet and not more than 50 acres. The reclamation plan states that areas surrounding the future lake will be sloped to a maximum 4:1. Four inches of loamy on-site soils will be placed over the sloped areas. They will be seeded and mulched to establish vegetation. The ordinance requires this area to be planted with trees, shrubs, legumes or grasses. The Reclamation Plan addresses this by indicating uplands will be planted with a mix of native trees, shrubs, grasses, flowers and groundcover. The plan indicates that no areas will have slopes greater than 4:1, consistent with ordinance provisions. The ordinance requires that the bottom contour of any lake shall be gradually sloping from the shoreline to the Scandia Planning Commission Page 9 May 2, 2008 Tiller Corporation, CUP for Mining deepest portion of the water body with a maximum slope of 6 feet horizontal to 1 foot vertical for at least 100 feet from the proposed shoreline toward the center of the water body. Beyond 100 feet in horizontal distance, the slope of the bottom contours may be no steeper than 3 feet horizontal to 1 foot vertical. The Typical Section Edge of Water Body shown on Figure C3 meets these requirements. Section 8.4 of the Mining Ordinance addresses excavations which must be graded or backfilled. The applicant has provided a Soil Balance Calculation. Based on this information, 1.77 million cubic yards (cy) of material will be needed for final reclamation at slopes not to exceed 4:1. According to the information provided there are about 1 million cy of overburden material yet to be excavated and 125,000 cy of material is already stockpiled. Reject material is expected to be 800,000 - 900,000 cy. Based on this information, it appears there is adequate material (1.92-2.02 mcy) to meet reclamation requirements. The Reclamation Plan also states that additional clean fill may be brought to the site for shaping and grading to establish final restoration grades and prepare for final development. If additional fill is brought in, the City must approve that importation and it must be inspected and certified (8.4(1)). The Reclamation Plan shows three surface water management ponds surrounding the lake. Although the application addresses best management practices during operation, there is little discussion of how surface water quality will be maintained after complete reclamation. This must be addressed. The area is to be contoured to a gently rolling topography. The plan states that the maximum slopes will be 4:1, and if sufficient material is left over, the slopes will be reduced. The ordinance states (8.4(6) "such topsoil shall be planted with trees, shrubs, legumes or grasses."The Reclamation Plan proposes grasses, native trees, shrubs, flowers and groundcover. The final elevations planned for building purposes must not be less than 10 feet above the normal ordinary groundwater level. Plans for on-site septic systems must be considered. The owner has indicated that a joint sewerage system will probably be employed. Since most drainage from the site will remain on the site, it is not expected that there will be any adverse effects to public roads or neighboring uses. Issues/Recommendations • The parcel owned by the operators consists of 395 acres, with 155 acres to be actively mined and reclaimed. The area is zoned A-4 Agriculture, which allows an overall density of one unit per 10 acres. A sizeable portion in the southwest side of the property is within the Shoreland Overlay designation. The overall number of units possible on the site is approximately 39. The Concept Ultimate Use Plan prepared for Washington County shows approximately 58 units. If clustering (under the Open Space Conservation Subdivision provisions of the Zoning Ordinance) is proposed, it is possible to increase the density above the base density, but the owners should not assume bonuses above the underlying density. The City of Scandia, by approving a Reclamation Plan, makes no promises or commitments relative to the concept plan. Based on that plan, the City will expect the planned end use to be residential. The operator must make sure there are adequate areas for house pads and either on-site septic systems or a communal system. Scandia Planning Commission Page 10 May2 2008 Tiller Corporation, CUP for Mining ' • The Reclamation Plan states that no slopes will exceed 4:1, and depending upon available overburden and topsoil, the slopes will be less. The final slopes on this site cannot exceed 4:1. • From the information provided in the Soil Balance calculation, it appears there are adequate soil reserves on site to conform to City slope standards. If the owner needs to import additional fill, it must notify the City and comply with the certification requirements of the ordinance. • No overburden or topsoil can be removed from this site, since the City prefers final slopes less than 4:1. • The process for stabilizing the soil must use prescribed methods and seed mixtures as per the most recent Mn/DOT Native Seeding Manual, as stated in the Reclamation Plan. • The Reclamation Plan has identified where there will be ponding areas when the land is ultimately reclaimed. The plan does not address in detail the measures to assure these ponds do not become stagnant or other maintenance measures. • The ordinance calls for a combination of trees, shrubs, legumes and grasses. The reclamation plan generally calls for grasses, trees, shrubs, etc. Today, most of Scandia is a mixture of grasses, scattered trees and woodlands. In order to restore the area into the surrounding landscape, some native trees should be included in the Reclamation/Restoration Plans. As the time for final restoration is to occur, the applicant must refine the landscaping part of the plan to assure trees on reclaimed areas before actual construction of any houses. • The Reclamation Plan does not link the life expectancy of the mining operation to the reclamation phases. • The Reclamation Plan is imprecise. It states that reclamation will proceed concurrently with mining operations: "Reclamation activities which take place during the past mining season as well as reclamation activities planned for the subsequent mining season will be discussed in each annual report." In order to provide a time frame within which to conduct the reclamation, the City will recommend timing for initial restoration phases, which will be enforced through the AOP process. - Reclamation Area 1 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2011 season. - Reclamation Area 2 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2015 season. - Reclamation Area 3 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2018 season. - Reclamation Area 4 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2021 season, depending upon progress of mining activities. Scandia Planning Commission Page 11 May 2, 2008 Tiller Corporation, CUP for Mining - Reclamation Area 5 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2024 season, depending upon progress of mining activities. — Reclamation Area 6 will consist of backfilling, sloping and vegetating this area. This should be accomplished in the 2028 season, depending upon progress of mining activities. - Final Reclamation will include removal of any equipment, and any backfilling and seeding of the operations area. - It is expected that the reclamation will proceed concurrently and proportional to actual mining operations. Progress on concurrent reclamation as demonstrated in the AOP application, may allow reductions in portions of the Letter of Credit for reclamation on a five-year basis. • Section 9.3 of the Mining Ordinance provides for a financial guarantee to the City to assure compliance with the Reclamation Plan. The guarantee can take the form of a Letter of Credit or other security satisfactory to the City in the amount determined by the City. The applicant has provided a detailed cost estimate for reclamation, based on the original Reclamation Plan submitted. This estimate of$205,227 (in 2008 dollars) should be verified by the applicant in light of the revised Reclamation Plan reviewed here. Assuming a 20 year life span, and an annual inflation rate of 3 percent, ultimate reclamation costs in 20 years would be$328,500. The Mining Ordinance does state that "the operator shall be entitled to a reduction in the security amount on a dollar for dollar basis as reclamation is completed and approved by the City Engineer, except that the security shall not be reduced below an amount equal to 125 percent of the cost of the work to be completed as determined by the City Engineer nor below 5 percent of the security, unless the reclamation has been accepted by the City." • The Applicant must demonstrate that there is sufficient material on the site to complete the reclamation efforts. The City may increase the required financial guarantee if additional material needs to be imported to the site to complete the proposed reclamation. • After final reclamation, usage of the lake should be limited to non-motorized boats or boats with electric motors. • The applicant must address these issues, and prepare a final, separate Reclamation Plan based upon these recommendations. That final Reclamation Plan, which will require approval by the City, will form part of the basis for approval of the Annual Operating Permit. This Reclamation Plan shall be updated every five years. Screening, Berniing and Related Site Issues The site plan (Sheet C-1) provided by the applicant indicates the existing fencing, berming and plantings. The additional berming noted on the plan along the northeast edge if the site will be required for approval of the CUP. Scandia Planning Commission Page 12 May 2, 2008 Tiller Corporation, CUP for Mining The Reclamation Plan(Sheet C-3) includes the proposed seed mixes and maintenance for reclamation areas. These are appropriate and acceptable. Field visits to this site revealed that existing reclamation efforts have experienced significant erosion on planted areas that is compromising the success of the reclamation efforts. It is recommended that erosion control fabrics or other geotextiles be incorporated where needed in reclamation areas in addition to seeding, particularly in areas of concentrated storm water flows, to prevent erosion. Reclamation efforts will be monitored by the City, and where erosion issues are identified, the Applicant will be required to use appropriate methods to control erosion and assure the success of reclamation efforts. Bioengineering approaches that result in a natural appearance on the reclaimed areas should be utilized. PLANNING STAFF RECOMMENDATIONS: The proposed plans and supporting materials provided by Tiller Corporation, meet the requirements of the City's Code for issuing a Conditional Use Permit.

LEGGETTE, BRASHEARS & GRAHAM, INC. PROFESSIONAL GROUND-WATER AND ENVIRONMENTAL ENGINEERING SERVICES 8 PINE TREE DRIVE SUITE 250 ST.PAUL,MN 55112 (651)490-1405 FAX(651)490-1006 www.lbeweb.com April 29,2008 Ms. Sherri Buss, R.L.A. Senior Planner/Landscape Architect TKDA 1500 Piper Jaffray Plaza 444 Cedar Street St. Paul,MN 55101-2140 Re: Hydrogeologic Evaluation Aggregate Mining and Related Activities Tiller Corporation City of Scandia,Minnesota Dear Ms. Buss: Leggette, Brashears & Graham, Inc. (LBG) was retained by TKDA to review the Tiller Corporation (Tiller) Conditional Use Permit (CUP) Application for the purpose of identifying data gaps and potential ground-water issues that could result from current and proposed mining activities. The information provided below provides TKDA and the City of Scandia (City), Minnesota with LBG's comments and recommendations. The CUP Application, dated November 2007, was prepared by Sunde Engineering, PLLC (Sunde) on behalf of Tiller for the aggregate mining and processing operation (site) located on Manning Trail North in the City. The location of the site is shown on Figure 1. LBG conducted an initial review of CUP Application and related information in March 2008. From this review process, LBG identified specific portions of the CUP Application that required additional information and/or clarification on ground-water related issues. LBG prepared a series of questions that outlined these data gaps, which were submitted to Sunde through TKDA. At the time of our initial review, the information that was either missing or incomplete included: well logs for site wells; a request for proposed well construction for future observation wells; soil boring logs and survey data (including a map); site feature labeling on maps; historical water level data; information regarding potential hydraulic separation of different aquifers; information regarding the hydraulic connection between German Lake and the water table aquifer; and, confirmation of the water appropriation permit number for the on-site Production well and whether the Scale House well was appropriated. Sunde responded in writing on April 15, 2008. LBG has reviewed this recent information and found that it sufficiently addresses our questions with the exception of the items presented in the general comments section below. Attachment 1 includes Sunde's responses to our questions and the supplemental information provided. CONNECTICUT•OHIO•ILLINOIS•SOUTH DAKOTA•PENNSYLVANIA•FLORIDA•NEW JERSEY•TEXAS WISCONSIN•NEW YORK•MISSOURI•VERMONT•MICHIGAN Ms. Sherri Buss 2 April 29,2008 General Comments 1) Sunde Responses to LBG Questions: The supplemental information that was requested by LBG and provided by Sunde (see Attachment 1) should be included in the CUP Application. In general, Sunde's additional information shows the Tiller site is well characterized and the proposed monitoring plan will ensure any potential ground-water related issues are addressed. 2) Section II-Figures 4 and 5: Sunde should revise these figures to include a scale. 3) Section II- Figures C-5 through C-9: Sunde should revise cross section A-A' through J- J' to include tie lines (i.e. notes that indicate where a cross sections intersect). A note should be added on each cross section stating the date the water table surface elevations were determined. 4) Section II 9 F-MN County Well Index(CWI) Search: Well information from the CWI was provided by the City in a Memorandum dated April 1, 2008 for those wells located within a 1-mile radius of the site. The City also completed a drive-by search for residences not identified in the CWI that are within a 1/2 mile of the site. Given the results of this search, the proposed on-site monitoring well locations, and the monitoring plan in the CUP Application, LBG agrees that the existing well search information is sufficient at this time. 5) Section II 9 G, 0, P - Depth to Ground Water and Flow Directions: The three on-site piezometers will provide sufficient information to determine depths to ground water, ground-water elevations, and flow direction of the water table aquifer across the site. Current data shows ground water in the water table aquifer flows to the northwest. The addition of the upgradient well proposed for the Dresel site and the proposed downgradient well on the Tiller site will better characterize these conditions. 6) Section II 9 0 - Hydraulic Connection to German Lake: LBG has reviewed the available information from Barr Engineering, Emmons & Olivier Resources, and Sunde in regards to German Lake and the potential impact to this lake as a result of mining below the water table. LBG agrees with the conclusions presented in these documents that withdrawl of gravel below the water table will have a negligible long-term effect on the water table and German Lake. This conclusion is based on the hydrogeology of German Lake and the surrounding area. This lake and other shallow wetlands in the area are created by surface water runoff and shallow ground water that remain suspended or perched above the regional water table aquifer. Clay layers above the water are typically responsible for creating these perched features, which are not hydraulically connected to underlying water table aquifer. Tiller has a proposed a monitoring plan that be able to address any potential impact to the water table and German Lake. 7) Section II 9 0 - EAW: LBG has reviewed the ground-water sections of the EAWs that pertain to ground water, the other information provided to date, and the proposed ring plan that will be implemented as part of the CUP Application. With respect to ground-water, LBG agrees with the 1987 and 1999 EAWs regulatory findings and the negative declarations for an EIS. 8) Section II 9 P: The CUP Application states that a diesel range organics (DRO) will be monitored in the existing and proposed wells. However, DRO does not identify the full gasoline range organics (GRO) spectrum. If gasoline is to be stored on site, then GRO and benzene should be added to the list of analytical methods. Ms. Sherri Buss 3 April 29, 2008 9) Section III 7: Ground water will be extremely vulnerable as the mine will proceed below the water table. Appropriate precautions and contingencies should be in place so as to limit the potential for introducing contamination to the environment. Recommendations Given the general comments above and from our review of the CUP Application and subsequent information provided by Sunde,LBG has the following recommendations for the Tiller site. 1) At this time, LBG does not see a need for Tiller to install more wells in the sand and gravel other than those already proposed. The existing and proposed monitoring well network appears to be sufficient and will characterize the depth to ground water and flow direction across the site in the water table aquifer. 2) LBG recommends that Tiller keep records of when the Production well is pumping. 3) Water-level measurements should be collected monthly for the first year and quarterly thereafter to evaluate seasonal variation in water elevation and to evaluate potential hydraulic connection between the sand and gravel aquifer and German Lake. Monitoring frequency should be increased in wells closest to the area where mining occurs below the water table when mining into the water table 4) LBG agrees that ground-water samples should be analyzed for DRO. However, if gasoline is to be stored on site,then GRO and benzene should be added to the analyte list. 5) At this point, given the current well search data provided and the proposed on-site monitoring well network, LBG does not recommend further investigation and monitoring off-site residential wells. The proposed monitoring well network appears to be sufficient to identify potential impacts that may migrate off site. 6) The recommendations provided above do not include concerns presented in the Memorandums by Emmons & Olivier Resources (EOR), dated March 25 and April 1,2008. LBG recommends Tiller comply with the EOR recommendations as well. If you have any questions concerning this review,please contact us at(651)490-1405. Sincerely, LEGGETTE, BRASHEARS &GRAHAM, INC.

Tiller 1) Please provide well logs for the Production Well, Scale House Well, PZ-1,PZ-2, and PZ- 3. What are their MN Unique ID#s? The logs of the test borings and the well logs on file at the MN Department of Health for PZ-1, PZ-2 and PZ-3 are attached. The unique numbers are: PZ-1:436181 PZ-2:436182 PZ-3:436183 Note that the location of the piezometers is incorrect on the County Well Index map. The log of the production well is attached. The MN Unique Well No. is 168714 We do not have a copy of the scale house well. Both the production well and scale house well were installed by a previous property owner. 2) What is the proposed well construction and expected depths of PZ-4, PZ-5, and PZ-6? Are these to be completed in the sand and gravel? Bedrock? The wells are proposed to be 2"Sch 40 pvc wells and 10 foot slotted pvc screens with a plugged end. Filter pack will be installed around the screen to two feet above the top of screen,followed by a bentonite plug and cement grout. A protective casing set in neat cement with locking cap will be placed over the capped well. If any of the monitoring wells are in excess of fifty feet then a stainless steel screen may be used. We would propose to finish these wells in the Quatemary Drift,with ten foot screens intersecting the groundwater table. Because of the fluctuation of the groundwater table we would try to finish,each well so that it intersects the upper two thirds of the ten foot screen. That way if the water table drops five feet due to seasonal fluctuations,water level measurements and samples would still be feasible. The depth will depend upon the final location of the wells, the surface elevation and estimated groundwater depths at the locations. 3) Are any of the existing wells completed in the bedrock or are they in sand and gravel? The piezometers and the production well are all completed in the sand and gravel. We ✓ do not know what the scale house well is finished in. Two wells that were associated with the homestead in the eastern portion of the property A z:L '"%oS were sealed in accordance with Minnesota Department of Health rules. Both of these wells were bedrock wells. Copies of the sealing records are attached (H243537 and H175503). 4) Section 0, page 9, 3rd paragraph states that Figure 5 illustrates locations of wells/piezometers and soil borings. The soil borings are not shown on Figure 5. Please provide a map showing the locations of the soil borings and provide the boring logs. A copy of Figure 5 is attached. The fourth soil boring is now shown. The soil boring locations are shown on this figure. The location or elevation of SB 11 was not surveyed ✓ in at the time it was drilled, therefore the water table elevation is approximate only and the water table recorded to the nearest five foot interval. Information from the previous permit applications from the Dresel site indicated a water level of 916 feet above mean sea level (msl)at the Dresel site, so the information from SB 11 is consistent with other available data. A copy of the boring log for SB 11 is attached. 5) Are the buildings on Figure 5, midway between the Production Well and PZ-1, the refueling area and asphalt plant? If not, please provide a map showing these site features and identify them as such. The buildings referred to above are associated with the asphalt plant. Figure 5 has been revised to label the plant area. 6) Please provide historical groundwater level measurements from observation wells on site or adjacent to the site that have monitored by Tiller. Tabulated values or well hydrographs would be sufficient. We are attaching a pdf of a.1g88 roundwater invstioation by Dr. Hans-Olaf Pfannkuch. This study was conducted in conjunction with the conversion of the wet scrubber pollution control system associated with the asphalt plant to a baghouse system which eliminated any wastewater discharge. As part of the conversion, the wet scrubber discharge pond was removed under guidance from the Minnesota Pollution Control Agency(MPCA). An investigation and the technical report was prepared and approved by the MPCA. The study contains historic groundwater level data from the three piezometers. The technical/ report concludes that flow directions near the plant area are in the northwesterly direction. As part of the study soil samples were taken to obtain laboratory values of hydraulic conductivity. Average bulk flow velocities were shown to be on the order of 35- 50ft/year corresponding to bulk travel time for 1 mile of 100-150 years. Based on this information, it is clear that an on-site monitoring well network with properly located monitoring wells will be able to detect impacts to groundwater quality long before any off- site migration or impacts to residential wells could occur. The county permit did not require water level readings so a continuum of water level readings does not exist. The production well was fitted with a port in 2006 to allow static / water level reading. The scale hsau a well could not be modified. Water level measurements of the production well and PZ-3have been taken since September 2006. o'i " (4,261 It should be noted that during the active mining season, the production well is utilized for L, dust control pumping anywhere from 15,000-25,000 gallons per day. This may have 11,„i 1y.finfluenced some of the water level readings. Copies of the more recent water level 4 readings are attached. L 7) Are there survey data for the soil borings (i.e., grade elevation at the boring location when it was drilled)? If so, please provide. This will help determine/verify the accuracy of the groundwater elevations used to estimate flow direction. The location and elevation of the measuring point of the piezometers was surveyed at the time of the Pfannkuch report. I could not find any information relative to the surface elevation. Construction logs are included and the length of pipe above ground is noted, so a reasonable estimation can be made. Tiller also surveyed PZ-3, the production well and the scale house well more recently as part of starting to take water level readings in 2006. The survey information in Washington County Coordinates is as follows: PZ-3: X=489110 Y=292899 Z=952.23 (at measuring point) Production well: X=488770 Y=292904 Z=942.98(at measuring point) Scale house well X=488986 Y=292681 Z=940.47 (top of well) 8) The EAW(Aug, 1999; Section 13)indicates the DNR Appropriations Permit Number for a 16"onsite well(Permit No. 86-6193, MN Unique ID#168714). Is this for the Production Well or Scale House Well? Is there a permit for the other well? if so, please provide the permit number. Also, as indicated above, please provide the MN Unique ID#s. The well r/1 `-f 5 log for CWI Unique ID#168714 does not indicate the name of the well (Production Well c-3, 1 '5 or Scale House Well). Ir le; ie The water appropriations permit is for the production well(unique#168714). The scale ;, V' house well is a potable well that does not meet requirements for an appropriations permit. A. �t� x 9) Are the drift and Prairie du Chien—Jordan aquifers hydraulically separated? If so, provide any site-specific data stratigraphic data and for head data to indicate separation of the two flow systems. We do not have site specific data to determine whether or not the two aquifers are connected or not. Review of well log data in the area is inconclusive. 10)The Camelian-Marine Watershed District(CMWD)completed a study of German Lake (indicated on page 4 of the April 21,2006 letter from Barr to Ann Terwedo, Washington County). If this is available, please provide a copy? Were there any concluding statements as to the hydraulic connection between German Lake and the water table aquifer in this report? The CMWD should be able to provide you with a copy of their study. Attached is a memo from Stu Grubb,with Emmons& Olivier Resources, Inc., consultants for the CMWD. His memo indicates that German Lake is perched. We know that the elevation of the groundwater table in the active mining area is around an elevation of 916 feet above msl. The elevation of German Lake, approximately 2,300 feet to the west, is at an elevation of approximately 954. For the two systems to be connected a rather strong west to east gradient would be expected. The Pfannkuch study did not find this to be the case. ✓ Hopefully the installation of PZ-5 will be able to confirm the configuration of the water table in this area. In any event, the Barr study which evaluated the impact of mining below the water table on German Lake assumed that the two systems were connected. This would be the conservative assumption to use in analysis of this nature. If German lake is in fact perched,the impacts would be even less. There are several isolated wetland basins it the area between the active mining limits and German Lake. These basins are perched above the regional water table. r.

Tiller Corporation owns and operates a gravel mining and processing operation within the City of Scandia. The site has been actively mined since at least 1966. Prior to the incorporation of Scandia in 2006, New Scandia Township and Washington County were the permitting authorities, first issuing permits in the late 1980's. Permitted activities include the removal and processing of aggregate, the production of hot- mix asphalt and the recycling of concrete and asphalt products. Final product is sold locally. The operation is located on approximately 395 acres, of which a total of 155 acres will be mined and reclaimed at the conclusion of the mining operation. Environmental review for the mining facility, in the form of an Environmental Assessment Worksheet (EAW), was completed in 1987 as part of the initial permitting process. A second EAW was completed in 1999 due to revisions to mining limits. Mining limits were revised by adding areas to be mined to the eastern side of the property and removing areas to be mined that were more environmentally sensitive on the western side of the property. The scope of operations and mining limits proposed in this permit application are consistent with the scope of operations and mining limits reviewed in the 1999 EAW. II. SITE INFORMATION 1. Name and address of operator and owner of the land: Tiller Corporation 7200 Hemlock Lane, Suite 200 P.O. Box 1480 Maple Grove, MN 55311-6480 2. An accurate legal description of where the mining shall occur: 1 The legal description of the site is included as Attachment 1. 3. Names and addresses of adjacent property owners within %2 mile of the perimeter of the area being or to be mined: A list of Tax Parcel Identification Numbers has been supplied to the City. The City will obtain a list of all property owners within a %2 mile of the perimeter of the property from Washington County. 4. A narrative outlining the type of material to be excavated, mode of operation, estimate of amount of material to be removed, plans for blasting, estimated time to complete the removal, and other pertinent information to explain the request in detail: The mining operation includes removal of overburden, excavation of sand and gravel, crushing, washing, screening, stockpiling, recycling of concrete and asphalt products, the production of hot-mix asphalt and reclamation activities. The site usually operates on a seasonal basis from approximately mid April to mid November depending upon weather conditions. Plans included in this submittal illustrate the current status of mining activity, the locations of operations, phasing, proposed reclamation grades and potential restoration. Overburden is removed from areas to be mined and is stockpiled on site and later used for reclamation of completed phases. Aggregate is excavated above groundwater using front end loaders. A dragline or excavator will be used to excavate material within the groundwater. Processing consists of crushing, screening, washing and stockpiling. Recycling of concrete and asphalt occurs at the site and consists of crushing, screening and stockpiling. Some of the processed aggregate and recycled product is loaded on trucks using front end loaders, the trucks are weighed and the product is delivered to projects throughout the area. The balance of the processed aggregate and recycled product is used in a hot-mix asphalt plant which operates at the site. Front end loaders place specified aggregates into different cold feed bins. The aggregates are metered out of the bins onto a conveyor which delivers the aggregate into a rotating drum where they are blended together, heated and dried. Heated asphalt cement and recycled asphalt are mixed with the heated aggregate and conveyed into insulated overhead silos. Trucks drive under the silos to get loaded and weighed and then deliver the product to projects through out the area. 2 The asphalt plant is equipped with a baghouse air pollutant collection device and operates under a Minnesota Pollution Control Agency (MPCA) Air Emissions Permit. Fuel and asphalt cement are stored at the site. All storage tanks have secondary containment and are operated in compliance with MPCA regulations. An estimated 8 to 9 million cubic yards (cy) of aggregate reserves remain at the site. Based on previous activity, annual production at the site is 300,000 to 400,000 cy. Based on current production rates, the estimated life of the facility is about 20 to 30 years. However, the actual life of the site will be dependent upon future market demand. Blasting does not occur at this site. 5. Fee: The required application fee has been submitted to the City. 6. Survey indicating property boundaries : A survey of the site including property boundaries is included as Sheet C1, Existing Conditions Plan. 7. Map of property indicating where mining is to occur and other significant features as required in Ordnance 103: Sheet C2, Site Plan, illustrates the site property lines, limits of proposed excavation, setbacks, and topographic data at two foot vertical intervals. Water courses, wetlands, wooded areas, rock outcrops, power transmission poles and lines, and other significant features are also shown. 8. General Location Map and aerial photo: A General Location Map, a 2005 Aerial Photo and a USGS Quad Map Excerpt, are included as Figures 1-3 respectively. These figures show the existing mining site in relation to the community. 9. Maps and Plans showing the following for the site and within 300 feet of the perimeter of the mine: A. Roads or streets showing all access routes between the property and the nearest arterial road, identifying name, right-of-way width and traveled portion width. 3 Main access routes to and from the site are County Road 15A (Manning Trail N.) and County Road 1 (Lofton Avenue). These are paved roads. The haul road off of Manning Trail N. is paved through the site to the hot-mix asphalt plant and loading area. The names, right-of-way widths, and traveled portion width of all adjacent roads are illustrated on Sheet C1, Existing Conditions Plan. B. Easements Plan with widths and purpose. Easements, with widths and purpose are illustrated on Sheet C1, Existing Conditions Plan. C. Natural land features showing locations of watercourses and drainageways, flood elevations, wetlands, sinks, basins and wooded areas. The locations of natural land features are illustrated on Sheet C2, Site Plan. D. Natural resources including other surface water, groundwater depth, flora, fauna, and any other natural features in the rural environment. The locations of natural land features are illustrated on Sheet C1, Existing Conditions Plan. E. Manmade features such as buildings and other structures, dams, dikes, and impoundments of water. Man-made structures are indicated on Sheet C2, Site Plan. F. Adjacent land features with all of the requirements included above within 300 feet of the perimeter of the mine, and all platted subdivision lots, metes and bounds parcels, and homes within '/4 mile of the property boundaries. Wells should include private/agriculture, industrial, municipal wells within 1/2 mile radius of the mine. Adjacent land features are shown on Sheet C2. Platted subdivision lots, metes and bounds parcels, and homes within 1/4 mile of the property boundaries are shown on Sheet C1. All wells within 1/2 mile radius of the facility, which are on file at the Minnesota Department of Health's County Well Index, are indicated on Figure 4. 4 G. A minimum of 1 cross section for every 1000 feet running north/south and east/west, showing the extent of overburden, extent of sand and gravel deposits, the groundwater level, and any evidence of the groundwater level in the past. A series of six north/south and four east/west cross sections are included as Sheets C5-C9. These cross sections depict the existing elevation, overburden, final elevations, extent of deposit, and the elevation of the groundwater. Soil borings were completed as part of the original permitting process. The soil borings were used in developing the site cross sections. H. All processing areas and boundaries shown to scale. Processing areas are identified on Sheet C2, Site Plan. I. All access roads within the site to processing and mining areas shown to scale: Access Roads to the processing and mining areas are indicated on Sheet C2, Site Plan. J. Sequences or phases of operation showing approximate areas involved shown to scale and serially numbered with a description of each. There are essentially three phases remaining at the site. Mining will occur above the groundwater and into the groundwater concurrently in each of the remaining phases. Mining into the groundwater typically occurs once a mining facility begins to mature. A fairly large floor area is needed for a stockpile area, a processing area and an area to begin excavation into the groundwater. This facility has reached the stage where the floor area is large enough to accommodate mining into the groundwater. In addition, due to the variable nature of the aggregate deposit, it is necessary to mine above and below the groundwater concurrently in order to obtain the proper blend of aggregates. Each total phase ("a" and "b" inclusive) represents approximately five to ten years of mining activity depending upon aggregate quality and market demand. The sequence of operations showing the approximate areas involved in the various phases of the operation are indicated on the Phasing Plan, Sheet C4. 5 K. Location of screening berms shown to scale, and notes provided indicating when they will be used as reclamation material. In the same manner overburden storage areas must be identified and noted. The location of screening berms and overburden stockpile areas are indicated on Sheet C2, Site Plan. Currently, when overburden is being removed from a new area to be mined, every effort is being made to use that material in ongoing reclamation. The majority of the existing screening berms will be used in final reclamation. L. Fences and gates and their type or construction described and illustrated: Locking gates are indicated on Sheet C2, Site Plan. Three strand wire fence surrounds the majority of the site. Some areas of the site are not fenced due to topographic conditions and wetland areas. Locking metal gates are located at each of the site entrances. M. Proposed location of principal service or processing buildings or enclosures as well as locations of settling basins and process water ponds: There is a quality maintenance building (QM Lab) that is used for testing the hot mix asphalt, an equipment storage building used to store equipment and parts and a control building for the asphalt plant. A scale office is located above the QM Lab and is used for the asphalt plant and mining operation. There are no process water ponds located on site. There are no permanent sedimentation ponds for washing operations. These ponds are located near the portable wash plant when it is brought to the sight. When washing operations are complete, the silt in the sedimentation ponds is dried, blended with overburden materials and used for reclamation. The location of the buildings and enclosures are indicted on C2, Site Plan. N. Existing site drainage features and flow directions indicated. A plan for handling surface drainage during operation and after final reclamation, consistent with local surface water management plans. Surface water will be managed during active mining in accordance with the site's NPDES Stormwater Pollution Prevention Plan (SWPPP) and consistent with local surface 6 water management plans. This plan includes a number of best management practices (BMPs) which are incorporated into daily site operations. The BMPs have been designed and implemented to avoid untreated stormwater discharge from the site, minimize potential for erosion and sedimentation throughout the operation of the site and provide for site stabilization at the conclusion of mining activity. Erosion and sedimentation control practices used on site during active mining include silt fence, vegetated screening berms, stormwater sedimentation ponds, wetland buffers and dust control. Silt fence is placed as necessary along the limits of each mining phase in areas where topography does not accommodate internal surface water drainage next to sensitive areas. Screening berms around the perimeter of mining area are vegetated to reduce erosion and to help contain fugitive dust. A sedimentation basin is located on the floor of the mining operation to handle internal drainage. When needed, water from the sedimentation basin is pumped upland to a secondary sedimentation basin for additional treatment. Vegetative buffer strips are preserved around wetland areas. These buffer strips filter runoff and reduce the potential for sedimentation to occur within the wetland basins. Erosion and sedimentation control practices after final reclamation include achieving permanent stabilization of the site through proper reclamation design standards. After mining is completed, reclamation will be performed to restore the site to a stable condition, minimize the potential for erosion and allow for future development of the land. Reclamation will involve slope stabilization, seeding and mulching. The Mining and Reclamation Plan, Sheet C4, indicates proposed site elevations upon completion of restoration. Slope stabilization will be accomplished by backfilling and grading the side slopes to a maximum of 4:1 in upland areas. A minimum of four inches of loamy soils, suitable as topsoil, will be placed on the graded slopes. After topsoil has been placed, the slopes will be seeded and mulched to establish vegetation. Slopes around the water's edge will be 6:1 or less for a distance of 100 feet waterward. Upland will be planted with a mix of native trees, shrubs, grasses, flowers and groundcover. O. A plan for groundwater quality protection to include a minimum of three soil borings showing depth to groundwater. Protection of the quantity and quality of groundwater resources is vital. Groundwater is a valuable resource that is used as the source of drinking water to area residents. Additionally, groundwater interacts with, and plays an important role in sustaining, several high value surface water resources within the region. Removal of aggregate into the groundwater and the creation of a groundwater lake was part of the overall plan for the site when it was initially permitted. Mining into the groundwater will take place for three to five months per year. The material is stockpiled and allowed to dry for a period before it is blended with the material above the groundwater and processed. An area of three to four acres in size will be mined into the groundwater each year. Environmental review evaluating the potential for significant environmental impacts as a result of mining into the groundwater and creating the lake has been completed for the site. Two Environmental Assessment Worksheets for the project which included mining into the groundwater table have been completed. The EAW's for the site examined the potential for significant environmental effects. This included effects from mining that result in the creation of a groundwater lake. During this process, Washington County hired Barr Engineering Co. (Barr) to perform a hydrogeologic investigation of the impacts of mining into the groundwater. One of the components of the hydrogeologic study was to determine the immediate and long-term impacts of development of a 50 acre surface water feature on the surficial aquifer and on German Lake. The report indicated that the analysis used conservative values and neglected the water present in the soil voids. Estimated peak rate removal rates of 233 gallons per minute resulted in a predicted drawdown of 0.2 feet at German Lake. The report indicates that actual drawdowns would probably be less since excavation is not expected to occur constantly. The Barr report further determined that "the average withdrawal rate over a period of thirty years is equivalent to a pump removing 1.7 gallons per minute. Even if the entire pond area 8 were excavated in one year the pumping rate would be equivalent to 51.63 gallons per minute. It may be seen that the long term pumping rate will be far less than the peak rate analyzed above and that long-term effect of the pit expansion will be negligible". In the spring of 2006, the Washington County hired Barr to review and update their report. The 2006 Barr review reiterated that the "equivalent groundwater pumping rate caused by the withdrawal of gravel from below the water table would have a negligible long-term effect on the water table." (emphasis added) Soil borings have been drilled on the site and used for the purposes of defining subsurface conditions at the site, including four borings that extended into the groundwater table. Past hydrogeologic investigations have been completed at the site and provide additional groundwater data information within the mining area. A production well located on site yields additional groundwater elevation information. Figure 5 illustrates the locations of these wells/piezometers and soil borings. The mining operation is located in an area characterized by the prevalence of very granular, permeable and non-reactive soils with very low filtering capacity typical of sand and gravel deposits. These characteristics however, are associated with a high sensitivity to groundwater contamination. If contaminants are introduced into the soil column, groundwater may be impacted within a very short time frame. There are a number of site BMPs and technologies available that are discussed below which eliminate or reduce the potential of introduction of contaminant sources into the soils. Groundwater Protection Plan • Elimination of industrial wastewater discharges associated with the asphalt plant. The asphalt plant is currently equipped with a baghouse to reduce air emissions. No water is used in the operation of the asphalt plant. • Limited equipment maintenance is performed on-site and follows company spill prevention policies. • A service truck comes to the site to perform routine maintenance. All used lubricating oil is collected by facility 9 personnel and hauled off-site to a central collection point (waste oil is not classified as hazardous waste). The service truck carries a spill containment kit. • All storage tanks are above ground and have secondary containment. Secondary containment consists of an impermeable concrete enclosure with a concrete base. The portion of the containment area with the used oil and fuel tanks also has an impermeable membrane on top of the concrete. In the event of a tank failure the secondary containment prevents the release of petroleum products to the environment. • A Spill Prevention Control and Counter Measures Plan (SPCC Plan) has been prepared for the site. This plan documents procedures to be followed in the event of a spill or release at the site. Company policy regarding spills is that any spill of oil, gasoline, diesel fuel, lubricant, or asphaltic cement is to be reported to Paul Schultz P.G., Tiller's Land Use Coordinator, and cleaned up promptly. Any spills of 5 gallons or more of petroleum products or any volume of hazardous materials are reported to the state duty officer as required by applicable state statutes and regulations (Minn. Stat. 299K) • Topping off tanks of any kind is not allowed under company procedures. All transport piping is above ground and tanks are equipped with audible electronic alarms to prevent over filling. Warning signs and chock blocks are used to prevent premature vehicle departure. • Availability of spill cleanup equipment on-site including equipment to excavate and remove impacted soils in an expedited fashion, as well as fire fighting extinguishers, absorbent pads, spill blocker dikes, empty barrels, rags and shovels. Protective measures in addition to those outlined in the preceding section, have been adopted as part of extraction into the groundwater. They include: • Stormwater routing to prevent untreated stormwater runoff from entering the groundwater lake. • Berming and/or diversion of agricultural runoff from the mining area. 10 • Surface water monitoring and expansion of groundwater monitoring network. Measures to protect groundwater quality will be incorporated into final site design once final development has been determined. These will involve a variety of best management practices, including stormwater treatment, erosion control and vegetative filter strips. P. All mining operations must install one monitoring well. If the proposed mining operation will appropriate groundwater for use in mining operations, the operator shall install not less than one monitoring well down gradient of the mining operation. If the proposed mining operation will include mining into the groundwater table, not less than two monitoring wells shall be installed one up-gradient and one down-gradient of the mine. Groundwater Monitoring Plan Groundwater monitoring is conducted on an annual basis at the site. Currently the three on-site wells are monitored for Diesel Range Organics (DRO) on an annual basis. Samples are collected from the production well, the potable well that supplies the scale house, and from an on-site piezometer' installed during a previous groundwater study. Figure 5 illustrates the location of the monitoring points with respect to the mining operation. The elevation of the groundwater table and flow direction is also indicated on this figure. In the past, results of the water analysis were sent to the County and Township on an annual basis. In the future, monitoring results will be submitted to the City of Scandia. Upon issuance of the permit, monitoring will be conducted according to the following schedule: Well ID Parameter Frequency Scale House DRO Annual Production Well DRO Annual PZ-3 DRO Annual Production Well Water Level Spring/Fall PZ-3 Water Level Spring/Fall Two of the three piezometers installed during the groundwater study have been removed. P2 was removed to allow restoration of the northern 40 acres of the site. P1 was removed because it was located in an operational area. P3 continues to be sampled annually. 11 The monitoring well network will be expanded prior to mining activity into the groundwater. Three additional monitoring wells will be installed for the purposes of monitoring groundwater quality and quantity. These three monitoring points, in conjunction with the existing piezometer PZ-3 and the production well, will be used to record water levels twice a year during the spring and fall. One monitoring well, PZ-4, will be installed upgradient of the mining activity in the southeastern portion of the site. This well will help define the regional water table elevation in the southern portion of the site and provide background water quality information. Another well, PZ-5, will be installed in the western portion of the site, between the active mining limits and German Lake. This well will help define the regional water table in the western portion of the site and monitor fluctuations if any in the groundwater table associated with the mining activity. The last well, PZ6, will be located downgradient of the waterbody that will be created as a result of mining into the groundwater table. The well will also be located downgradient of the existing plant somewhere in the very northern portion of the site. The exact location of this well will be determined after the installation of PZ-4 and PZ-5 so that water levels from these two wells and PZ-3 and the production well can be utilized to select a location that is most representative of downgradient conditions. It is possible that PZ-3 may be used as the downgradient well. In addition to obtaining water level data from these wells, PZ-4 and PZ-6, the upgradient and downgradient wells will serve as water quality monitoring points for the purposes of tracking water quality in the lake and the groundwater. These wells will be sampled annually in conjunction with the lake water quality sampling episodes for nutrients (nitrogen and phosphorous), total suspended solids and DRO. The general locations of the monitoring wells are indicated on Figure 5. Wells PZ4, PZ5 and PZ6 will be installed prior to mining into the water table so at least one round of sampling can be taken to establish a baseline. Once the additional wells have been installed, the sampling schedule will be as outlined in the table below. Spring sampling will occur sometime within late April —May. Fall sampling will occur sometime within September— early October. Annual sampling will occur during the active mining season. 12 Well ID Parameter Frequency Scale House DRO Annual Production Well DRO Annual PZ-3 DRO Annual PZ-4 DRO Annual PZ-6 DRO Annual Water Body DRO Annual Production Well Water Level Spring/Fall PZ-3 Water Level Spring/Fall PZ-4 Water Level Spring/Fall PZ-5 Water Level Spring/Fall PZ-6 Water Level Spring/Fall PZ-4 Nitrogen/Phosphorous/TSS Annual PZ-6 Nitrogen/Phosphorous/TSS Annual Water Body Nitrogen/Phosphorous/TSS Annual Sampling results will be submitted to the City on an annual basis in conjunction with the annual report. The results will be reviewed to obtain a picture of the water quality coming into the lake, at the lake, and leaving the lake. The report will include previous years' data and will be in a spreadsheet or graph form to facilitate identifying trends in water quality. Results will be reviewed for any indication of impacts to water quality or quantity as a result of mining. It should be noted that fluctuations in groundwater levels can be expected in response to climatic conditions. Therefore, a review of surrounding observation wells finished in the same aquifer will be made to help evaluate the observations and correlate any trends seen in the facility's water levels with regional trends. Q. If lighting is proposed, a plan for lighting the area must be provided. The plan must comply with all City ordinances pertaining to lighting. Security lighting is provided around the quality control building and hot-mix asphalt plant. As daylight hours grow shorter in the fall of the year, lighting is provided for the hot- mix asphalt plant and the crushing and screening operations. The lighting structures are on the floor of the pit and the lights are hooded and directed downwards R. Reclamation plan in conformance with Section 8. 13 The Mining and Reclamation Plan, Sheet C3 is a graphic representation of reclamation activities. • Intent: The intent of reclamation activities covered in this section is to restore the site to a stable condition, minimize the potential for erosion and allow for future development of the land. • Methods and processes of reclamation: Reclamation will involve slope stabilization, seeding and mulching. Slope stabilization will be accomplished by backfilling and grading the side slopes to a maximum of 4:1. A minimum of four inches of loamy soils, suitable as topsoil, will be placed on the graded slopes. After topsoil has been placed, the slopes will be seeded and mulched to establish vegetation. • Initial condition of mining site: The site was an existing mining operation when Tiller Corporation began operating this facility. • Limits of various operational areas: The operational areas are indicated on the Site Plan, Sheet C2. • Phasing and timing of operations and reclamation including areas to be stripped of overburden. Phasing of mining operations is included on the Phasing Plan Sheet C4. Some reclamation activity has been completed. These areas are illustrated on the Site Plan, Sheet 2. Reclamation of sideslopes will continue as mining progresses around the perimeter of the excavation limits. • Final Condition of the site, including proposed contours and landscaping: The Mining and Reclamation Plan, Sheet C3, indicates proposed site elevations upon completion of restoration. • Relation of final site condition to adjoining land forms and drainage features within 1/4 mile. Reclamation of the site will result in a groundwater lake with open space around the lake, a substantial wooded area with isolated wetland basins in the western and southeastern portions of the site and upland areas in the eastern and northeastern portions of the site. • Relation of reclaimed site to planned or estab►ished uses of surrounding land: The land is designated general rural/agriculture with 4/40 densities. Surrounding land use is similarly guided. Established land uses are agricultural and rural residential in nature. 14 • A plan for maintenance of reclaimed area: See Mining and Reclamation Plan, Sheet C3. • A detailed cost estimate of reclamation and maintenance: Reclamation costs for the area currently opened to mining activity as well as the projected next five year phase are outlined below. A portion of Phase 1 will involve the creation of a water body and will not require topsoil and vegetation. The area where mining into the groundwater is to occur is currently disturbed therefore the numbers below are conservative. Final Grading: Placement of 4" topsoil from on-site stockpiles; 96 acres: 51,627cy at $ 1.00/cy $51,627 Finish grading of disturbed area; 96 acres: 96 acres at $1,000/acre $96,000 Seeding and Mulching 96 acres at $600/acre $57,600 Total reclamation costs; $205,227 Reclamation will proceed concurrently with mining operations. Reclamation activities which take place during the past mining season as well as reclamation activities planned for the subsequent mining season will be discussed in each annual report. Reclamation standards as included in Ordinance No. 103 Section 8.3-8.8 will be followed. S. If blasting is proposed as part of the mining operations, the operator must indicate frequency, timing, size, duration and develop a blasting plan: Blasting is not performed at this site. T. A description of any processing operations including washing crushing, recycling and bituminous plants and concrete ready- mix plants. 15 Aggregate is excavated above groundwater using front end loaders. A dragline or excavator is used to excavate aggregate within the groundwater. Processing at the site generally includes crushing, screening, washing, sorting and stockpiling of aggregate, recycling of concrete and asphalt by crushing, screening and stockpiling and the production of hot-mix asphalt. A hot-mix asphalt plant operates at the site. Front end loaders place specified aggregates into different cold feed bins. The aggregates are metered out of the bins onto a conveyor which delivers them into a rotating drum where the aggregates are blended together, heated and dried. Heated asphalt cement and recyclable asphalt are mixed with the heated aggregate and conveyed into insulated overhead silos. The asphalt plant operates under MPCA Air Emission Permit Number 00001987-001 (AQD File Number 1394A). The asphalt plant is equipped with a baghouse air pollutant collection device. The mining and aggregate processing, recycling and hot-mix asphalt production activities all operate in compliance with applicable Federal and State standards and the operating standards of Ordinance No. 103. III. OPERATING CONDITIONS 1. Setbacks: Mining, stockpiling or land disturbance activities, with the exception of berming and visual screening, will be setback 50 feet from an adjoining property line, 200 feet from an occupied structure, 100 feet from any contiguous property subdivided into residential lots of 5 acres or less, and 100 feet from any road right-of-way. As shown in the attached plan set, the setback along the common mining boundary to the south will be 0'. 2. Fencing: The entire site is fenced with 3 strand wire fencing except where prohibited due to topography and wetlands. There are locking metal gates at both entrances to the site. 3. Hours of operation: The site is operated from 7:00 a.m. to 7:00 p.m. Monday through Friday except holidays. Extended hours may be required periodically for situations such as emergencies, accelerated work 16 schedules or weather delays. If operations are required beyond the 7:00 a.m. to 7:00 p.m. hours, or on Saturdays, Sundays or holidays, prior permission will be obtained from the City of Scandia in accordance with procedures set forth in Ordinance No. 103. 4. Screening: The site is operated in a manner to minimize the visual impact of the extraction and processing area on surrounding properties. In addition to the wooded buffer areas that separate the mining activity from surrounding properties, a large number of trees have been planted in the past to screen site activities. Processing and stockpiling operations are conducted in recessed portions of the site to minimize visibility. Established screening berms are shown on Site Plan, Sheet C2. 5. Dust control: Dust is generated by crushing and screening equipment, excavation and loading equipment, and vehicular movement. Vehicular dust generation is minimized by paved access roads. Processing areas are located at elevations lower than the surrounding terrain in order to minimize windborne dust leaving the site. A water truck is used to water unpaved portions of the site. The sand and gravel activities at the site operate under General Air Emission Permit Number 05301018-001, which is issued by MPCA. 6. Noise: Noise is generated from processing activities, loading processes, and vehicular movement. Noise is minimized by conducting processing activities within the interior of the site at elevations lower than the surrounding lands. All activities are conducted so as to be in accordance with all Federal, State and County noise standards. 7. Depth of excavation: Depth of excavation will be limited by the practical limits of the equipment which is 45 feet below the water table or approximately 870 feet above mean sea level. 8. Site clearance: Trees, stumps, roots and other vegetative material removed during site clearance or other activities will be disposed of by logging and/or chipping. Logged material will be used for lumber or 17 firewood. Chipped material will be used as mulch, bio-fuel at approved facilities, erosion control devices or other approved utilizations. 9. Appearance/condition: All buildings, plants and equipment at the site will be maintained in a neat condition. Weeds and other unsightly or noxious vegetation shall be controlled as necessary to preserve the appearance of the reclaimed areas. 10.

When production equipment is present, an additional 1,000-gallon double walled tank is brought to the site and used to fuel processing equipment. All asphalt cement storage tanks are above-ground. These tanks consist of two 40,000 gallon tanks and one 20,000 gallon tank. There is also a 20,000 gallon above-ground used oil storage tank. The used oil is used as an alternative fuel supply for the asphalt plant. All tanks are within the secondary containment area and are registered with MPCA's Storage Tank Program. MPCA Site ID 51999 is for the asphalt plant and MPCA Site ID 55016 is for the sand and gravel operation. Small amounts of chemicals utilized by the QM Lab are regulated by Washington County under United States Environmental 18 Protection Agency (EPA) rules. EPA ID Number MND 981 953 417 has been issued for the site and it is classified as a Very Small Quantity Generator. The site has obtained a National Pollutant Discharge Elimination System (NPDES) Permit as required by EPA and issued by MPCA. This permit requires that the site operates under the associated Stormwater Pollution Prevention (SPP) Plan. A copy of the NPDES Permit and SPP Plan will be supplied to the City 14. Contingency Response Plan: As stated previously, the site operates under a SPCC Plan. SPCC Plan. This is required by EPA regulations and Tiller will submit necessary portions of the SPCC Plan to the City and the City's fire department. In addition, the site is subject to reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA), also known as Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA). These Acts are administered by Minnesota Emergency Response Commission (ERC) which is part of Minnesota Homeland Security and Emergency Management, a division of Minnesota Department of Public Safety. The site's ERC ID Number is 82-125-0001. The required reporting under EPCRA and SARA includes submitting a Tier II Chemical Inventory to the City's fire department. This is done on an annual basis. 15. Added Provisions: The operator will comply with other such reasonable requirements that the City may find necessary to adopt for the protection of health, safety and welfare and/or prevention of nuisance. 16. Processing: The site operates permanent processing equipment in accordance with all Federal State and City air and water quality and noise standards. Processing equipment is screened from view from other properties and adjacent roads. Crushing equipment is placed on the floor of the facility and setbacks per Ordinance No. 103 are maintained between the processing equipment and the property lines. 19 17. Recycling: Recycling at the facility will meet all applicable standards contained in Section 7.1 (1) of Ordinance No, 103. The estimated volume of materials recycled on an annual basis is approximately 50,000cy asphalt and 25,000cy concrete. The stockpile of material to be recycled will not exceed the volume of material that can be processed in two consecutive operating seasons. 18. Trucking Operations: The site has access to County Road 15 (Manning Trail) and County Road 1 (Lofton Avenue). These are paved 9 ton roads. The haul road off of Manning Trail is paved through the site to the hot-mix asphalt plant and loading area. Trucks are loaded so as to comply with state law. Loose material is cleaned from the trucks and tires before the leaving the facility. 19. Asphalt Plants and Ready-mix plants: The site operates a permanent hot-mix asphalt plant and the plant was in operation at the time the City adopted its mining ordinance. Therefore the plant may expand in the future subject to the setbacks set forth in Section 7.1(1) of Ordinance No. 103. The plant operates in accordance with all Federal, State, and City air, water and noise quality standards. The site operates under an air quality permit issued by the Minnesota Pollution Control Agency. IV.

Tiller Corporation. November 2007. Groundwater Quantity No apparent hydraulic connection exists between the regional water table (elevation approximately 920 ft) and German Lake or the nearby wetlands (water elevation approximately 953 ft). A confining layer apparently keeps the lake and wetlands perched above the regional water table. The cross sections and text of the permit application should show and discuss this feature. It is unlikely that further excavation of the pit downward and to the east will have additional impacts to German Lake and the wetlands. Because there is no hydraulic connection between the pit and German Lake,the previous calculation or model indicating that the removal of water from the pit during mining operations will have minimal effect on German Lake is not relevant. The calculation does indicate that effects on water levels in nearby wells will be minimal, which is also important. The perched aquifer system is unusual in the watershed district and Washington County, so the applicant should expect careful scrutiny of water levels in German Lake, the wetlands, and the pit. If falling water levels are noted in German Lake or the wetlands, the watershed district and others should re-examine the groundwater data and conceptual model in the area of the pit. Groundwater Quality Asphalt plant Groundwater below the gravel pit is highly susceptible to contamination. A spill of petroleum products or other liquids would reach the groundwater almost immediately. CMSCWD recommends that the City of Scandia carefully consider the risks associated with permitting an asphalt plant in the Tiller mine. The Washington County Groundwater 2007 Work Plan (p. 18) states that the County will require plans for servicing of equipment, waste disposal, and groundwater protection and will require a bond to assure clean-up of any pollution.

Tel: (651) 770-8448• Fax: (651) 770-2552 Drinking water The City of Scandia is reviewing and permitting this proposed project as it relates to drinking water concerns. These comments are offered for their consideration. The process of mining into the water table will likely change the water chemistry at the site and migrating off the site. Changes in water quality parameters may result from moving and removing material from the pit. The proposed groundwater monitoring plan is adequate for detecting groundwater contamination due to spills, but it should be expanded to include the following parameters: Well ID Parameter Frequency Scale House, Production Total Suspended Solids, Annual Well, PZ-3, PZ-4, PZ-6 Total Dissolved Solids, pH, color, odor, hardness EozEMMONS & OLIVIER RESOURCES MEMORANDUM Date: April 23, 2008 To: CMSCWD Board of Managers From: Lisa Tilman, P.E. and Dan Fabian, P.E. Re: Summary of Review and Recommendations for Permit App. No. 08-003 Tiller Corporation Mining Operation, Scandia We recommend Managers authorize Administrator to approve and issue permit contingent on Applicant addressing following comments to satisfaction of District Engineer: Summary of comments to be addressed prior to permit issuance: 1. For the required review fees a deposit of$5,500.00 has been received as of 04/03/2008. Applicant is responsible for replenishing this deposit if it appears it will be insufficient to cover District review costs. The estimated completion date for this project is 20-30 yrs (we assume this means from today's date and not the 1960's starting date. The District's standard permit length is 1-year. Managers will need to determine duration District permit will be valid before it will need to be renewed. If permit length is longer than 1-year a minimum annual status update from applicant and site visit should be coordinated with Scandia CUP and issuance of Annual Operators Permit. Managers will also need to establish method to re- coup costs for annual reviews. 2. District surety still needs to be provided. The City of Scandia requires a surety as part of its Mining Ordinance CUP and Annual Mine Operators Permit. Managers should consult with City to see if an agreement can be made that District would not need to require a separate additional surety. Perhaps requiring the applicant to maintain a cash deposit with the District of some amount as part of the permit fee requirement would be acceptable. This would ensure that District would recoup on-going review fees, while any major issues could perhaps be addressed through coordination with the City's permit enforcement process. 3. The proposed total discharge rate offsite is the same as the total pre-settlement discharge rate offsite. The proposed total discharge volume offsite for the 2-year and 10-year event is equal to or less than to the total pre-settlement discharge volume offsite and to internal landlocked wetland basins. (Note Comment 5 below as related to Wetland 8.) 4. Identify 100-yr flood Elevation of proposed landlocked lake on plan sheet. Minimum design storm would be 100-yr 10-day Snowmelt. Starting lake elevation would be highest known groundwater elevation in lake area. Verify that lake will not discharge offsite. 5. Proposed construction of groundwater lake: Page 2 3/23/08 Tiller Corporation Mining Operation Review a. The proposed site plan results in a final condition with drainage to a proposed constructed landlocked "lake" in the groundwater. Proposed lake bottom contours need to be provided before we can provide comment on proposed lake construction. b. The direct connection to groundwater during mining and after reclamation of the site makes the site vulnerable to contamination of the groundwater table. The proximity of the asphalt plant to the lake also increases risk. It is our understanding that the City of Scandia has hired experts to look into this issue in depth,particular any potential impacts to neighboring drinking water supply wells. A trigger needs to be established for removing the asphalt plant and perhaps the recycle operations prior to the lake being constructed. Say when the open water portion of the lake gets within 500-ft of the asphalt plant or recycle operations. Refer also to attached memo from FOR groundwater specialist. c. Neither existing nor proposed rules specifically address creating of a small lake, either groundwater or surface water dependent. ■ A lake management plan needs to be provided addressing the design of the lake, the ecosystem and protection of water quality during and after construction. Proposed construction plan needs to be consistent with the lake management plan. This should be done prior to construction of the proposed lake. ■ The lake if not properly designed and constructed so it functions properly has the potential to be an undesirable eye sore rather than an amenity to the area. d. Future district development reviews will likely treat lake as a groundwater dependent natural resource. 6. During mining activity, stormwater will be treated through settling in a detention pond in the mined area and pumped for secondary treatment in a detention pond at original ground elevation. The secondary pond discharges to an onsite wetland, Wetland 8. The submitted modeling does not take into account this source of drainage to Wetland 8. The contributing surface drainage area of Wetland 8 is also proposed to be reduced under proposed conditions. a. Provide operations plan for pumping of sedimentation basin. Initial conversations with Tiller Representatives indicated that sediment basin in the pit is pumped into another treatment basin that overflows, through a piped outlet, into Wetland 8. Pumping activities are stopped prior to water levels in the second treatment basin outletting into Wetland 8. b. Drainage computations for impacts to Wetland 8 need to take into account pumped flows from the pit sediment basin. c. Revise proposed grading limits so that the drainage area of Wetland 8 is not changed from existing conditions. Once the wetland has been delineated and if proof is provided and accepted that the reduction in drainage area will not negatively impact the function or value of Wetland 8, applicant could submit a revised grading plan for approval. 7. Include in plans procedures for loosing of soil to restore Soil permeability prior to final planting and site restoration. Concern is that under the reclaimed condition if B soils are used as fill, (as currently proposed) and they are heavily compacted during placement, soils will function like C soils and runoff will increase. Page 3 3/23/08 Tiller Corporation Mining Operation Review GENERAL COMMENTS AND BACKGROUND INFORMATION The Tiller Corporation Mining Operation is located between Manning Trail and Lofton Avenue south of 228th Street in Sections 7 and 8, T32N, R2OW in the City of Scandia, MN (see Figure 1 for location map). The property is located in both the Carnelian Marine St. Croix Watershed District and the Comfort Lake Forest Lake Watershed District. The proposed project entails the continuation of gravel mining and processing activities on a 395 acre lot. The project includes crushing and washing of gravel, recycling of concrete and asphalt, and production of hot-mix asphalt. Mining will occur within the groundwater table. The project will disturb a total of 155 acres through mining to an elevation of approximately 870 ft., 45 feet below the water table. The groundwater elevation is estimated to be about 916 ft. based on past groundwater monitoring not submitted to the District at this time. A portion of German Lake, a groundwater-dependent natural resource, is located on the property. Additionally, 22 wetlands are located on the site, eight of which are located within the CMSCWD. Mining will not occur within the shoreland management district of German Lake and no alterations are proposed within the drainage areas of any wetlands within CMSCWD except Wetland 8. The reclaimed condition of the site will be a 50-acre "lake" created in the groundwater table in the center of the active mining area along the CMSCWD eastern boundary. In order to evaluate the proposed mining activities at the Tiller Corporation Gravel Mine in Scandia, the following review evaluates the proposed activities with respect to the standards of the current and proposed Carnelian Marine St. Croix Watershed District(CMSCWD) Rules. Permit application is for completion of planned mining activities through complete restoration of vegetation for entire site. Any further proposed development of site following completion of mining activities will require a new permit application submittal and will need to meet the district permit requirements applicable at the time of submittal. The Carnelian Marine St. Croix Watershed District (District) initially provided review comments to Scandia on this project that primarily pertained to the completeness of information received by City to meet District permit submittal requirements, in our letter dated January 24, 2008. All remaining materials, needed for a complete District Permit Application for this project, were received on April 4, 2008. The District also provided input to Scandia during development of their Mining Ordinance in 2007.

TKDA 444 Cedar Street,Suite 1500 Saint Paul,MN 55101 Dear Sherri: I am writing in response to your May 1, 2008 e-mail to Kirsten Pauly with Sunde Engineering, PLLC. You were requesting information about the permits/regulations and safeguards that are in place for Tiller Corporation's (Tiller's) asphalt plant and how these permits/regulations and safeguards address potential spills or potential pollution issues. Our Conditional Use Permit Application dated November 2007 talks extensively about the permits,regulations, 1...� licenses designed for pollution control. It also talks about pollution safeguards, plans and policies (collectively known as Best Management Practices BMPs) to prevent or address releases or spills. The information in our Application includes: • Elimination of industrial wastewater discharges associated with the asphalt plant. The asphalt plant is currently equipped with a baghouse to reduce air emissions. No water is used in the operation of the asphalt plant. • Limited equipment maintenance is performed on-site and follows company spill prevention policies. • A service truck comes to the site to perform routine maintenance. All used lubricating oil is collected by facility personnel and hauled off-site to a central collection point (waste oil is not classified as hazardous waste). The service truck carries a spill containment kit. • All storage tanks are above ground, have secondary containment and are registered with the Minnesota Pollution Control Agency( MPCA). Secondary containment consists of an impermeable concrete enclosure with a concrete base. The portion of the containment area with the used oil and fuel tanks also has an impermeable membrane on top of the concrete. In the event of a This Company is an Equal Opportunity Employer May 1,2008 Page 2 of 4 tank failure the secondary containment prevents the release of petroleum products to the environment. • A Spill Prevention Control and Counter Measures Plan (SPCC Plan) has been prepared for the site. This plan documents procedures to be followed in the event of a spill or release at the site. Company policy regarding spills is that any spill of oil, gasoline, diesel fuel, lubricant, or asphaltic cement is to be reported to Paul Schultz P.G.,Tiller's Land Use Coordinator, and cleaned up promptly. Any spills of 5 gallons or more of petroleum products or any volume of hazardous materials are reported to the state duty officer as required by applicable state statutes and regulations (Minn. Stat. 299K) • Topping off tanks of any kind is not allowed under company procedures. All transport piping is above ground and tanks are equipped with audible electronic alarms to prevent over filling. Warning signs and chock blocks are used to prevent premature vehicle departure. • Availability of spill cleanup equipment on-site including equipment to excavate and remove impacted soils in an expedited fashion, as well as fire fighting extinguishers, absorbent pads, spill blocker dikes, empty barrels, rags and shovels. Protective measures that will be implemented as part of extraction into the groundwater include: • Stormwater routing to prevent untreated stormwater runoff from entering the groundwater lake. • Berming and/or diversion of agricultural runoff from the mining area.. • Surface water monitoring and expansion of groundwater monitoring network. All fuel and chemicals stored on site are stored in accordance with Federal and State standards. On-site fuel storage consists of a 1,000- gallon above-ground storage tank which is located within a concrete secondary containment area. When production equipment is present, an additional 1,000-gallon double walled tank is brought to the site and used to fuel processing equipment. May 1, 2008 Page 3of4 All asphalt cement storage tanks are above-ground. These tanks consist of two 40,000 gallon tanks and one 20,000 gallon tank. There is also a 20,000 gallon above- ground used oil storage tank. The used oil is used as an alternative fuel supply for the asphalt plant. All tanks are within the secondary containment area and are registered with MPCA's Storage Tank Program. MPCA Site ID 51999 is for the asphalt plant and MPCA Site ID 55016 is for the sand and gravel operation. Small amounts of chemicals utilized by the QM Lab are regulated by Washington County under United States Environmental Protection Agency (EPA) rules. EPA ID Number MND 981 953 417 has been issued for the site and it is classified as a Very Small Quantity Generator. The site has obtained a National Pollutant Discharge Elimination System (NPDES) Permit as required by EPA and issued by MPCA. This permit requires that the site operates under the associated Stormwater Pollution Prevention (SPP) Plan. A copy of the NPDES Permit and SPP Plan has been supplied to the City. As stated previously, the site operates under a SPCC Plan. SPCC Plan. This is required by EPA regulations and Tiller submitted necessary portions of the SPCC Plan to the City. In addition, the site is subject to reporting requirements under the Emergency Planning and Community Right-to-Know Act(EPCRA), also known as Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA). These Acts are administered by Minnesota Emergency Response Commission (ERC) which is part of Minnesota Homeland Security and Emergency Management, a division of Minnesota Department of Public Safety. The site's ERC ID Number is 82-125-0001. The required reporting under EPCRA and SARA includes submitting a Tier II Chemical Inventory to the City's fire department. In order for the SPP Plan, the SPCC Plan and the BMPs to be successful, requires that our employees understand the plans and practices as well as be trained in implementing them. This training takes place on a continuing basis both formally and informally. The records show that Tiller has been successful preventing releases at this facility and we are confident our employees will respond effectively should a release or spill occur. Currently the three on-site wells are monitored for Diesel Range Organics (DRO) on an annual basis. Samples are collected from the production well, the potable well that supplies the scale house, and from an on-site piezometer installed during a May 1, 2008 Page 4 of 4 • previous groundwater study. In the past, results of the water analysis were sent to the County and Township on an annual basis. We plan to expand this monitoring as presented in our application and the results will be submitted to the City. For your records, I have attached copies of our SPP Plan and SPCC Plan. I have also included a brief description of our contingency plan for petroleum spills and our safety procedures for unloading liquids. Please feel free to contact me if you have questions or need additional information. I may be reached at (763) 425-4191.
