CITY OF ST. ANTHONY VILLAGE WATER RESOURCES MANAGEMENT PLAN SECTION 2 Page 4 above. These are further addressed in the City’s MS4 permit, which is available from the City for review annually. The locations of the impaired water bodies within or downstream of the City are shown on the water resource problem areas map, Figure 7, Appendix A. The City will be required to implement the TMDL plans for the water bodies listed above once complete. 2.6.3. R-1A Single-Family Lakeshore The City of St. Anthony Village has adopted the R-1A Single-Family Lakeshore zoning designation to ensure the preservation of natural areas within that specific residential zone. A copy of specific zoning requirements in this area can be found on the City’s website. The City of St. Anthony Village does not have floodplain management regulations. 2.7. 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. 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. RCWD is charged with general responsibilities for groundwater protection and use, but its role is limited to cooperating and assisting the DNR, MDH and MPCA in their groundwater protection efforts. Within the City of St. Anthony Village, ground water wells serve the City and private water needs. Each of these wells has a ground water appropriation permit from the DNR. Figure 11, Appendix A shows the types and locations of the DNR permitted ground water appropriation sites within the City. The City of St. Anthony Village’s ground water flows generally from north to south through the Prairie Du Chein-Jordan Aquifer, and from the northeast to southwest for the St. Peter and Mt. Simon Aquifers. The City does not contain any significant ground water recharge areas, and a moderate to low rating for pollution sensitivity of the Prairie Du Chein-Jordan Aquifer. Additional water resources information for the City of St. Anthony Village may be found in the Ramsey County and Hennepin County Geologic Atlas, the Ramsey County and Hennepin County groundwater plans, and the City’s Wellhead Protection Plan. The primary recharge areas into the Prairie Du Chein Aquifer are located north of St. Anthony Village in the City of Arden Hills. The City’s water supply has been contaminated by the Twin Cities Army Ammunition Plant (TCAAP) site and the City operates a granular activated carbon water treatment plant to remove the pollutants. Further information, including pollutant levels, is available in the Annual Water Quality Report found on the City’s website. 2.8. Hydrologic System and Data A water quality model has been developed to provide additional information on water quality within the City. Since this model was completed, the Apache Plaza site in northern St. Anthony
