This is a Class D facility. The existing Facility presently serves approximately 75 homes. There are 70 individual septic tanks and 46 shared STEP systems through which sewage passes before entering the collection system. This Facility consists of small diameter force main, two lift stations, a stilling basin comprised of three septic tanks in series (7,500 gallons total), a dosing station and three pass-through sand filter beds, and a dosing station for filtered effluent going to a three -cell drainfield trench system. The drainfield system consists of three cells of drop box drainfields with ten laterals each. One or two cells rest at any given time. The system is designed to treat up to 19,800 gallons per day. There are no known bypass points in this system. There are four monitoring wells at this site, one up gradient (GW001) and three downgradient (GW004, GW006 and GW008). There are also nine piezometers (GW009-017).

R. ch. 7041. The conditions for septage treatment and application described in this chapter apply only to septage from domestic residences as described in the permit application. For the purpose of this permit chapter, solids collected in septic tanks are referred to as biosolids. If any commercial or industrial user is added to this permitted facility, the MPCA must be notified before adding that user to the facility so that appropriate monitoring, treatment and disposal of the septage can be determined. Based on that determination, the Permittee may be required to apply and pay for a permit modification. 1.2 Permittees who prepare bulk biosolids must obtain approval of the sites on which bulk biosolids are applied before they are applied unless they are Exceptional Quality Biosolids. Site application procedures are set forth in Minn. R. ch. 7041.0800. 2. Compliance Responsibility 2.1 The Permittee is responsible for ensuring that the applicable requirements in this chapter and Minn. R. ch. 7041 are met when biosolids are prepared, distributed, or applied to the land. 3. Notification Requirements 3.1 The Permittee shall provide information needed to comply with the biosolids requirements of Minn. R. ch. 7041 to others who prepare or use the biosolids.

Domestic Wastewater -- Biosolids-Domestic Septage (No Analysis Required) 4. Pathogen and Vector Attraction Reduction 4.1 Biosolids shall be processed, treated, or be incorporated or injected into the soil to meet pathogen and vector attraction reduction requirements in Minn. R. ch. 7041.1800, subp. 3, items a, b, or c as follows: a. the pH of the septage must be raised to 12 or higher for 30 minutes by alkali addition and, without the addition of more alkali, shall remain at 12 or higher for 30 minutes; b. the septage is injected and no significant amount of the septage is present on the land surface within one hour after it is injected, or c. the septage is incorporated below the surface of the land within six hours after surface application. 4.2 The minimum duration between application and harvest, grazing or public access to areas where biosolids have been applied to the land is as follows: a. 14 months for food crops whose harvested parts may touch the soil/biosolids mixture (such as melons, squash, tomatoes, etc.), when biosolids are surface applied, incorporated or injected. b. 20 months or 38 months depending on the application method for food crops whose harvested parts grow in the soil (such as potatoes, carrots, onions, etc.). The 20 month time period is required when biosolids are surface applied or surface applied and incorporated after they have been on the soil surface for at least four (4) months. The 38 month time period is required when the biosolids are injected or surface applied and incorporated within four (4) months of application. c. 30 days for feed crops, other food crops (such as field corn, sweet corn, etc.), hay or fiber crops when biosolids are surface applied, incorporated or injected. d. 30 days for grazing of animals when biosolids are surface applied, incorporated or injected. e. One year where there is a high potential for public contact with the site, (such as a reclamation site located in populated areas, a construction site located in a city, turf farms, plant nurseries, etc.) and 30 days where there is low potential for public contact (such as agricultural land, forest, a reclamation site located in an unpopulated area, etc.) when biosolids are surface applied, incorporated, or injected. 5. Management Practices 5.1 The management practices for the land application of biosolids are described in detail in Minn. R. ch. 7041.1200 and must be followed unless specified otherwise in a site approval letter or a permit issued by the MPCA. 5.2 Overall management requirements: a. Biosolids must not be applied to the land if it is likely to adversely affect a threatened or endangered species listed under Section 4 of the Endangered Species Act or its designated critical habitat. b. Biosolids must not be applied to flooded, frozen or snow covered ground so that the biosolids enter wetlands or other waters of the state. c. Biosolids must be applied at an agronomic rate. The Agronomic application rate for septage applied to agricultural land, forest, or a reclamation site for a cropping year shall be calculated using the following equation unless determined otherwise by the MPCA. AR = N / 0.0026 Where: AR = Application rate in gallons per acre for the cropping year. N = The maximum available nitrogen application rate in pounds per acre per cropping year required by the crop based on realistic yield goals or nitrogen uptake by vegetation grown on the land minus the amount supplied by other sources such as manure or fertilizer. d. Biosolids shall not be applied within 33 feet of a wetland or waters of the state unless specified otherwise by the MPCA in a permit.

Existing discharges of non -contact cooling water to the Permittee's wastewater treatment facility shall be eliminated, where elimination is cost-effective, or where an infiltration/inflow analysis and sewer system evaluation survey indicates the need for such removal. 2.4 If the Permittee accepts trucked -in wastes, the Permittee shall evaluate the trucked in wastes prior to acceptance in the same manner as it monitors sewered wastes. The Permittee shall accept trucked -in wastes only at specifically designated points. (Minn. R. 7049.0140, Subp. 4) 2.5 Pollutant of concern means a pollutant that is or may be discharged by an industrial user that is, or reasonably should be of concern on the basis that it may cause the permittee to violate any permit limits on the release of pollutants. The following pollutants shall be evaluated to determine if they should be pollutants of concern: pollutants limited in this permit, pollutants for which monitoring is required in this permit, pollutants that are likely to cause inhibition of the Permittee's POTW, pollutants which may interfere with sludge disposal and pollutants for which the Permittee's treatment facility has limited capacity.

This is a Class D facility. Major components of the Facility include: 27 Individual Grinder Pumps 1 Septic Tank (7,500 gal) 1 Septic Tank (7,500 gal) - compartmentalized 1 Constructed Wetland - subsurface flow (9,000 sq ft) 3 Subsurface Mounds (19,718 sq ft) The application and plans indicate that the Facility is designed for 23 three and a half -bedroom homes and 4 three-bedroom homes in New Scandia Township, Washington County. There are currently 20 homes connected to the wastewater system. Each house has an individual grinder pump, which pumps the sewage through a two inch high-density polyethylene low pressure force main, approximately 4,000 feet in length. Wastewater flows through magnetic influent flow meters prior to two septic tanks operated in series. Both are 7,500 gallons, the first is un -compartmentalized and the second has 2 compartments. The second tank contains effluent filters. Next, wastewater is processed by one 9,000 square foot constructed wetland treatment system. A 5,000 gallon dosing tank doses a 19,718 square foot drainfield system (pressurized infiltration chambers) which consists of 3 zones with dedicated pumps to alternate usage of the zones. The Average Wet Weather (AWW) design flow is 8,925 gallons per day (gpd). The influent 5 -day Biochemical Oxygen Demand concentration is approximately 250 milligrams per liter (mg/L) and the Total Suspended Solids concentration is approximately 250 mg/L. There are no designated bypass points in the treatment system. This SDS Permit authorizes no discharge to surface waters. The location of the facility is shown on the "Topographic Map of Permitted Facility" (page 5). The location of designated monitoring stations is specified on the "Summary of Stations" (page 6).
