Natural Communities The majority of the City of Elk River has been categorized according to the Minnesota Land Cover Classification System(MLCCS). Figure 8 shows a map of the MLCCS areas that have been classified. 2.10. Groundwater Various agencies are responsible for groundwater management and protection.The DNR regulates groundwater usage rate and volume as part of its charge to conserve and use the waters of the state. For example,suppliers of domestic water to more than 25 people or applicants proposing a use that exceeds 10,000 gallons per day or 1,000,000 gallons per year must obtain a water appropriation permit from the DNR. Refer to Figure 10 for a map showing groundwater appropriations throughout the City. The Minnesota Department of Health(MDH)is the official state agency responsible for addressing all environmental health matters,including groundwater protection.For example,the MDH administers the well abandonment program and regulates installation of new wells. The MPCA administers and enforces laws relating to pollution of the state's waters,including groundwater. The Minnesota Geological Survey provides a complete account of the state's groundwater resources. The groundwater remediation system provides over 97 percent of the City of Elk River's annual water supply. 2.11. Pollutant Sources Refer to Figure 9 for approximate location of possible pollutant sources throughout the City. More information can be obtained by contacting the MPCA or going to www.mpca.state.mn.us and searching"What's in my neighborhood". The MPCA should be contacted for site-specific details. Other potential pollutant sources include industrial,office,commercial,residential and other highly impervious land uses. Stormwater runoff from these land uses could carry pollutants into the stormwater system(nonpoint source pollution),especially if there are direct inlets into the storm sewer system that do not drain first into a stormwater pond. Facilities within these land use types may be covered by a NPDES General Industrial Stormwater Permit,which requires Surface Water Management Plan City of Elk River Section 2 WSB Project No.1992-030 Page-5
