. b. The ultimate receiving body is the wetland shown on the attached map. The MnDNR has identified a 2 foot water bounce as desirable for wildlife associated with this pond. The City of Elk River platting process will require a specific water bounce calculation during each phase of the development. More onsite retention, or a metered outlet to the regional pond, can be added if so determined. , 19. WATER OUALITY - WASTEWATERS b. c. . a. Wastewater from the project will be limite~.~o domestic sewage and sewage typical of commercial uses and rest~urents. The City of Elk River, through its analysis, calculates domestic sewage use at 70 gallons per person per day. Residential wastewater produced is estimated at 60,060 gallons per day. Commercial wastewater produced is estimated at 25,900 gallons per day. Total estimated wastewater produced for the project is 85,960 gallons per day. Wastewater produced as a result of the project will be treated by the Elk River Wastewater Treatment Plant. Wastewater produced as a result of the project will be treated by the Elk River Wastewater Treatment Plant. The only pre-treatmenD anticipated will be grease traps for any restaurants and flammable waste traps for any motor vehicle service station activities. The lateral sanitary sewer lines will be extended to this project site from an existing trunk line with an existing MPCA permit. The project is on the fringe of the City of Elk River's urban service district; therefore, an extension of trunk sewer lines through the project will not be necessary. The City's Treatment Plant was recently in violation of effluent standards due to equipment malfunction. This situation has been rectified through agreement with the MPCA by temporary short term modifications and permanent renovations to the plant. According to this agreement, the plant will be able to accept the anticipated waste from this project. 20. GROUND WATER - POTENTIAL POR CONTAMINATION b. Soils are typically well drained, and the project area will be served by sanitary sewer instead of onsite septic systems, thereby eliminating concerns of sewage being a source of contaminant. c. No hazardous or toxic materials are proposed during construction of the project. Whether future use includes an auto service station is uncertain, but appropriate codes would regulate the use of such conditions as storage tanks and disposable wastes that could affect groundwater. 21. SOLID WASTES, HAZARDOUS WASTES, STORAGE TANKS a. The only solid waste from this site will be mixed municipal solid waste. Waste collection is performed under City franchise which requires mandatory garbage collection and curbside recycling for residential property. The City also requires garbage collection for commercial businesses and is in the process of developing a commercial recycling program. The City currently requires dumpster enclosures to be sized to accommodate recyclab1es. b. Future use could include tanks for an auto service station within the commercial area. Size and location are uncertain at this time since this use has not been determined to be included in the project site. .
