OPERATING CONDITIONS-EVALUATION FOR THE AOP
Site Operations-Background Information
The site includes several parcels, as indicated on the Site Plan(Figure C-1). Excavation activities in 2010 to
removed material between the Tiller site and former Dresel Mine site,merging the two sites into one.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 site usually operates on a seasonal basis from mid-April to mid-
November, depending on weather conditions.
Scandia City Council Page 5 March 15, 2011
Tiller Corporation AOP for Mining
The Applicant indicated that the site will continue to operate as it has in the past during the 201 i mining
season. Proposed active mining areas are indicated on the Site Plan(sheet C 1). The Applicant indicated that
enougtx material was processed at the site in 2010 to meet the estimated needs for 2011. Therefore,the
application indicates that processing activity is not planned at the site in 2011. If 2011 demand exceeds
forecasts, additional processing may be needed.
Mining into the groundwater began at the site in 2009. This activity has been described in the previous
mining plans for this site, and was evaluated in the Environmental Assessment Woz•ksheets completed for the
Tiller site in 198'7 and 1999. The 201 l AOP application indicates that no rraining into the groundwater is
expected in 2011.
The asphalt plant at the site is equipped with a baghouse air pollutant collection device, and operates u.nder a
Minnesota Pollution Control Agency(MPCA)Air Emissions Permit. Storage tanks as the site(for fuel and
asphalt cement)are regulated by the MPCA.
The main access routes to and from the site are Manning Avenue (County Road 15)and Lofton Avenue
(County Road 1). Both Manning and Lofton are paved.The haul road from Manning Avenue is paved
through the site to the hot-mix asphalt plant and loading area.
Annua!Ac[iviry
The application generally includes the data required by the ordinance regarding annual activity on the site, as
follows:
2009 2010
The amount of material removed from the site: 260,000 Tons 184,000 Tons
Amount of add-rock brought onto the site: 123,380 Tons 131,000 Tons
Recycled asphalt and concrete brought to the site: 67,500 Tons 20,000 Tons
Backfilling, sloping and seeding in the westem area Areas on map Areas on map
Average number of trips to and from the site each day: 230 trips 182 Trips
The Site Plan included in the application(sheet C1) shows the areas proposed for active mining and
reclamation activity in 2011.
Ground Water Monitoring Plan and Monitoring Issues
The approved Groundwater Monitoring Plan for the site is on file at the City.
LBG Analysis and Recommendations Based on ZO10 Monitoring Data
LBG reviewed the data and analytical reports from the monitoring wells on the Tiller site that were submitted
with the application, and indicated that no issues of concern related to the annual operating permit were
identified. The apptication notes that the water level in the groundwater pond was inadvertently not recorded in
conjunction with the fai12010 water level readings of the remaining wells. The app(icant indicated that the water
level will be i�ecorded in the early spring of 2013 and in the fall of 2011 to ensure sufficient water level data for
future evaluation of the groundwater and surface water relationships. LBG concurred with this approach. The
condition will be included in the conditions for the 2011 AOP.
Scandia City Council Page 6 March 15,2011
Ti11er Corporation AOP for Mining
LBG provided a hydrograph that illustrates the groundwater elevations on the site as part of their analysis
{attached).
Ground YYater Analysas. The results of the ground water analysis note that a sample taken from the pond on the
site in October,2010 identified Diesel Range Organics(DRO) at low levels (0.11 mg/I). The sample was further
analyzed for the presence of Polycyclic Aromatic Hydrocarbons (PAHs), which were not detected. Based on the
DRO detection, the pond was resampled for DRO in November 2010 at the request of the City. No DRO were
identified in the second sample, suggesting that there is no ongoing DRO-contamination issue. LBG identified no
issues related to the ground watei•analysis provided in the application.
Setbacks
The application indicates that the mining operation main#ains setbacks as follows:
• 50 feet from the adjoining property line
. 200 feet from an existing occupied structure
• 100 feet from residential property boundaries of 5 acres or less
• 100 feet from arny road right-of-way
The setbacks were reviewed at a site visit by City staff, and found to meet the requirements of Ordinance
103.
Fencing
The applicatian indicates that the majority of the site is fenced with 3-strand wire fencing, except where
prohibited due to topography,heavy vegetation and wetlands. There are locking metal gates at both
entrances. The fencing meets the intent of th�City's Ordinance. City staffreviewed the fencing during site
visits in 2009, and verified that it meets the requireznents of the Ordinarace and CUF.
Hours of Operation
The site is operated fronn 7 a.m.to 7 p.m. Monday through Friday, except holidays.The Applicant no#ed that
eartended hours were requested on several occasions in 2010 and approved by the City. The Applicant is
required to obtain the City's permission:for any extended hours in accozdance with procedures set in
Ordinance No. 103. The City received no complaints during any of the projects that operated with the
approved e�rtended hours.
Extended hours were requested to finish paving on MN Highway 243 and MN Highway 96, and to complete
interchange/overpass projects on Intersta.te 35 and 35E.
Screening
The application describes screening at the site, and notes that trees have been planted in the past to screen
site activities. No additional berms or plantings are proposed in 2011. The CUP did not require additional
screening.

The application indicates that truck opera#ions have access to County Road 15 (Manning Avenue)and
County Raad 1 (Lofton Avenue),which are paved roads.
The City received no complaints regarding trucking opera.tions associated with the site in 2010.
Asph�lt Plant
The site operates a permanent hot-mix asphalt plant that was in operation at the time the City adopted its
mining ordinance. The plant operates under an air quality permit issued by the MPCA. The City received no
complaints regarding the operation of the asphalt plant in 2010.
Reclnmation Plan
The applicant submitted a Reclamation Plan with the AOP application that combines the Tiller and Dresel
site reclamation plans.
The applicant indicated that the 2010-2011 Reclamation Activity area is approximately 3 acres in size. The
proposed Active Mining Area for 2011 is 27 acres.
Staff identified two issues related to the proposed rec�amation plan,based on the requirements of
Ordinance103:
1) Section 8.4 of the ordinance requires the following for reclamation areas where excavations will not
result in water areas after rehabilitation:
. All banks must be graded or backfilled;
e Graded or backfxlled areas shall be surfaced with soil of a quality at least equal to the topsoil
of areas immediately sur�ounding,to a depth at least four inches;
Scandia City Council Page 9 March 15, 2011
Tiller Corporation AOP for Mining
• The topsoil shall be planted with trees, shrubs,legumes or grasses
• Slopes shall not be steeper than 4:1
The reclamation plan included in the application plan indicates that reclamation will consist of
"sloping,backfilling, and establishment of vegetation." The application does not indicate that topsoil
will be applied as required, and does not indicate the specific types of plantings that will be included
in reclamation areas. T'he reclamation plan in the application should be updated by May 1,2011 to
meet the requirennents�f the ordinance,including placement of at least four inches of topsoil, and
specific infoimation regarding the proposed plantings for 2010.
2) Section 8.2 of Ordinance 103 requires the"restoration shal!proceed concurrently and proportional to
actual rnining operations,and will be subject to review and approval at each annual inspection and at
the end of the permit period." This section is included in the ordinance to ensure that:
• Large areas of the site are not left in an unreclaimed state,encouraging erosion, dust and weed
establishment
• The mining operation is making an ongong investnnent in reclamation,to avoid potential
problems that may occur at the end of the mining operation if a large investment is needed in
reclamation, and the applicant's resources are limited at that point, or the applicant abandons the
site.
The proposed active mining area for 2011 is nine times lazger than the area proposed for reclamation.
This is a signficant change from the relationship between the reclamation area and active nnining area
included in the 2010 Tiller application for the site.
The applicant should revise the reclamation plan to bring it in conformance with the ordinance by
May 1,2011,or provide a rationale for the lack of proportionality between the reclamation effort and
active mining on the site,and how this proportionality will be achieved in the future.
Relationship of Application fo Zavoral Mine ELS`
An Environmental Iznpact Statement(EIS)is currently in process for the proposed Zavoral Mine Site in the
City of Scar�dia. The project includes potential processing of material from the Zavoral Mine at the Scandia
Mine site in the future. This activity is not proposed at the Scandia site in 2Q10,and is not related to the
AOP application.
SITE INSPECTION
City staff completed site visits to the Tiller Corporation Mining Operation in during 2010,including
documenting conditions on the site in site photos. Pindings from the site visits are noted where appropriate in
the items above.
ACTION REQUESTED:
The City Council can:
Scandia City Council Page 10 March 15,2011
Tiller Corporation AOP for Mining
1. Approve the AOP;
2. Approve the AOP with conditions;
3. Deny the application if it is found that the request is not consistent with the Comprehensive Plan,
CUP,AOP Criteria,and Mining Ordinance, and is not in the best interest of the community;
4. Table the request if the Council needs additional information to make its decision.
PLANIVING STAFF RECOMMENDATIONS:
The Planner recommends approval of the AOP for sand and gravel mining and related processing,with the
following conditions:
1. The Applicant shalt continue to provide the production well records for the site to the City so the pumping
records can be compared to past and future groundwatec level treads at the site. The applicant should measure
the water level in the production well under non-pumping conditions during monitoring periods.
2. The application notes that the water level in the groundwater pond was inadvertently not recorded in
conjunction with the fa112010 water level readings of the remaining wells. The Applicant shall record water
levels in the pond in the early spring of 2011 and in the fa11 of 2011 to ensare sufficient water level data for
future evaluation of the groundwater and surface water relationships.
3. The reclamation plan shall be updated by May 1, 2011 to meet the requirements of the ordinance,
. including placement of at least four inches of topsoil, and additional information regarding the proposed
plantings for 2010.
4. The applicant shall revise the reclamation plan by May l,20i 1 to brring it in conformance with the
ordinance regarding proportionality of mining and reclamation areas, or provide a rationale for the lack
of proportionality between the reclamation effort and active nnining on the site,and how this
proportionality will be achieved in the future.
5. The Applicant shall provide the required Letter of Credit (LOC) or other security for Tiller's Scandia
Mine site and the former Dresel Mine site to the City by May 1, 20I 1.

APPLICATION FOR ANNUAL OPERATORS PERMIT
TILLER CORPORATION
SAND AND GRAVEL MINING OPERATION
CITY OF SCANDIA
WASHINGTON COUNTY, MINNESOTA
I. INTRODUCTION
The following Annual Operators Permit (AOP) application is submitted on
behalf of Tiller Carporation (Tiller) in compliance with the City of Scandia's
Ordinance No. 103 and Chapter 4 of the Development Code: Mining and Related
Activities Regulations, Section 6, adopted by the City of Scandia on August 28,
2007.
Ti11er operates a gravel mining and processing operation within the City of Scandia.
; ;�; The site has been active{y mined since at least 1966. Prior to the incorporation of
Scandia in 2006, New Scandia Township and Washington County were the
permitting authorities. The City of Scandia issued a Conditional Use Permit (CUP)
for the site in the spring of 200$.
{I. ANNUAL REPORT
A. Operating Conditions:
_ The site operates in accordance with operating conditions regulated by
Section 7 of the Scandia Ordinance 103.
1. Setbacks: No mining, stockpiling or land disturbance activities, with the
exception af screening activities, are proposed to take p{ace within the
setback areas. Minimum setback areas are maintained as follows:
. 50 feet from an adjoining property line
. 20Q feet from an occupied structure existing on May 20, 2008.
. 100 feet ftom any contiguous property subdivided into residential lots of
5 acres or less
. 100 feet from any road right-of-way.
2. Fencing: The majority of the site is fenced with 3 strand wire fencing
except where prohibited due to topography, heavy vegetation 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
Tiller Corporation Page 1
2011 Annual Operators Permit Application
� January 25,2011
i .
schedules or weather delays. In accordance with procedures set forth in
Ordinance No. 103, extended hours were requested and approved in
2010. As part of the request for extended hours, Tiller asked to be notified
if the City received any complaints regarding the extended hours of
operations. To Tiller's knowledge no complaints were received during any
of the projects operating with approved extended hours.
Extended hours were approved for the operation of the asphalt ptant,
including trucking operations, past 7:00 p.m. to finish paving MN Hwy 243.
By extending operating hours, Tiller's customer was able to complete
paving on Friday evening and lane restrictions were removed for weekend
travelers.
Saturday operations (asphalt plant and trucking, 7:04 a.m. to 4:00 p.m.}
� were requested twice and approved for interchange/overpass projects on
1-35 and I-35E. Saturday operations were necessary because MNDOT
- required ce�tain portions of the projects be completed on Saturday in order
to minimize impacts to weekday traffic.
Saturday operations (asphalt plant and trucking, 7:00 a.m. to 4:00 p.m.)
were requested and approved twice for paving on Hwy 96. Because of an
extremely rainy September this project was running well behind schedule.
Consecutive Saturday operations were requested in order to ge#the
project back on schedule and completed before the end of the season.
The weather turned very favorable for construction in October and the City
was notified that only the first of the finro approved Saturdays would be
needed.
4. Screening: Screening berms, wooded buffer areas and agricultural fields
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 po�tions of the site
to minimize visibility. Screening berm construction or modifications are
not anticipated during 2011.
5. Dust control: A water truck is used to water unpaved portions of the site to
control dust. During periods of increased trucking activity, calcium chloride
is applied to provide additional dust controf. These practices will continue
throughout the 2011 mining season.
fi. Noise: All activities are conducted so as to be in accordance with al1
.. Federal, State and City noise standards.
7. Depth of excavation: Depth of excavation will not exceed fifty feet below
the water table.
Tiller Corporation Page 2

$. Site clearance: A minimal amount of site clearing occurred during 2010 in
the old common mining border area as indicated on the site plan.
Clearing activity is not anticipated in 2011. Disposal of material from site
clearing activity takes place in accordance with the CUP application
materials. Trees, stumps, roots and other vegetative material removed
during site clearance or other activities are disposed of by logging and/or
chipping. Logged material is be used for lumber or fi�ewood. Chipped
material are 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 are
maintained in a neat condition. Weeds and other unsightly or noxious
vegetatian are controlled as necessary to preserve the appearance of the
reclaimed areas.

accardance with Federal, State and City requirements.
12. Water Quality Monitoring: A plan for groundwater monitoring has been
developed and approved in conjunction with the monitoring wells placed in
2008 and the CUP permitting process. Groundwater monitoring was
conducted in 2009 and 2�10 and the results were submitted to the City.
Water level data is summarized on Table 1 and water quality data is
summarized on Table 2. The water level in the groundwater pond was
inadvertently not recorded in conjunction with the fall 2010 water (evel
readings of the remaining wells. The water level will be recorded in the
early spring of 2011 and again in the fall in 2011 to ensure sufficient water
level data for future evaivation of the groundwater surface water
relationships.
13. Fuel and Chemical Storage: 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 and a five hundred
gallon above-ground double walled tank located next to the electricity
generafior. When production equipment is pres�nt, an additional 1,040-
ga{1on 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
Tifler Corporation Page 3
2011 Annual Operators Permit Application
January 25,2011
20,000 gallon above-ground used oil storage tank. The used oil is utilized
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 which is classified as a Very Small Quantity Generator.

submitted to the city and the fire department as part of the CUP process. � ,�
15. Added Provisions: The operator will comply with other such reasonable �
; requirements that the City may find necessary to adopt for the protection r��,, ,,,�/
of health, safety and welfare and/or prevention of nuisance. V 1�'U"'
I 16. Processing: The site operates permanent processing equipment as
' defined by Ordinance No. 103 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. Portable
crushing equipment is placed on the floor of the facility and setbacks per
Ordinance No. 103 are maintained between the processing equipment
' and the properiy lines.
97. Recycling: Recycling activity at the facility meets all applicable standards
contained in Section 7.1 (1) of Ordinance No, 103. Approximately 50,000
tons of Recycled Asphait Products (RAP) were processed in 2010.
Processed RAP is used in asphalt production or sold in various aggregate
products. The stockpile of material to be recycled does not exceed the
volume of material that can be processed in two consecutive operating
seasons.
� 18. Trucking Opera#ions: The site has access to County Road 15 (Manning
Trail) and County Road 1 (Lofton Avenue). These are paved 9 ton roads.
19. Asphalt 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

the past. The mining operation includes the removal of overburden, excavation
of sand and grave(, crushing, washing, screening, stockpiling, and recycling of
concrete and asphalt products. Portable crushing and screening plants are
' brought to the site periodically and material is excavated, processed, and
stockpiled. Hot-mix asphalt is produced and sold throughout the construction
' ` season and add rock materials are delivered to the site as needed.
Screening operations began at the site in late spring/earty summer 201 Q and
full processing activity in the fall of 2010. The 2010 production schedule was
put together so the season could end in Scandia. At that time, enough material
Ti{ler Corporation Page 6
2011 Annual Oparators Permit Application
January 25,2011
was produced to meet the anticipated needs for 2011. Therefore processing
activity is not planned +n 2011. However, if 2011 demand exceeds forecasts,
then there will be a need for additional processing in 2011. Excavation into the
water table began in the fall of 2009.
2. Site Plan: A site plan is attached which illustrates the areas planned to be
mined in 2011, the stockpile and processing area, and reclaimed areas.
3. Aerial Photo: An aerial photo is attached which illustrates the areas planned
to be mined in 2011, the stockpile and processing area and reclaimed areas.
4. Reclamation: Reclamation activities in 2010 consisted of placing
reclamation fill in the portion of the Site that was previously owned by Dresel
Contracting. This area is shown on the Site Plan.
As mining progresses to the perimeter of the mining area in the future, then
� reclamation consisting of sloping, backfilling and establishment of vegetation
can occur. Reclamation activities planned for 2011 will be similar to 2010
� activities.
� 5. Operating Conditions for 2011: Active mining will occur predominantly in the
areas indicated on the site plan.
D. Inspection:
The City conducts an annual inspection of the site. The last inspection
occurred on November 18, 2010.

Sherri,
The Tiller AOP appl looks fine. The only recommendation would be reference to the analytical report in tem no.7 and
on page 5,and provide the same that note in the text that explains the detection of 0.11 on 9/14/10 from the pond,and
that the resample was ND.
Page 6.C.2. : "Amount of add-rock brought onto the site in 2009." Should this be"2010"7
Page 7. D. 1. : State here that excavation below water table is not currently planned for 2011.
Updated hydrographs are attached.
