City of Arden Hills – 2040 Comprehensive Plan <br /> <br /> <br />Approved:, 2018 <br />13-6 <br />culverts, stormwater ponds and storm sewer pipes. The City of Arden Hills is <br />an MS4. <br /> <br />The MS4 general permit focuses on reducing the pollution that enters these <br />public systems and discharges to wetlands, streams and lakes (“waters of the <br />state”). The MS4 permitting program gives owners or operators of municipal <br />separate storm sewer systems approval to discharge stormwater to lakes, <br />rivers and wetlands in Minnesota. All owners or operators of MS4s are <br />required to satisfy the requirements of the MS4 general permit. <br /> <br />The MS4 general permit requires the MS4 operator or owner to create a <br />Stormwater Pollution Prevention Program (SWPPP) with six important <br />components (included in the attached MS4 permit): <br />o Public education and outreach, which includes teaching citizens about <br />better stormwater management. <br />o Public participation: Include citizens in solving stormwater pollution <br />problems. This includes a required public annual meeting and an <br />annual report. <br />o A plan to detect and eliminate illicit discharges to the stormwater <br />system (such as chemical dumping and wastewater connections) <br />o Construction-site runoff controls. This includes the implementation of <br />an Erosion and Sedimentation Control ordinance. <br />o Post-construction runoff controls <br />o Pollution prevention and municipal “good housekeeping” measures, <br />such as covering salt piles and street-sweeping. <br /> <br />13.1.3.4 Total Maximum Daily Load (TMDL) <br /> <br />Table 2.6 in Section 2 of the LSWMP (Appendix F) includes the TMDL listing <br />status for the major water bodies in Arden Hills or that receive drainage from <br />Arden Hills. Lakes Johanna, Josephine, and South Long Lake are listed for <br />mercury in fish tissue. Little Lake Johanna has a TMDL approved for chloride <br />and nutrients. The Upper Mississippi River has an approved TMDL for fecal <br />coliform. The Minnesota Pollution Control Agency (MPCA) is underway with <br />the remainder of the TMDLs for the waterbodies in Arden Hills. The City will <br />cooperate with the MPCA and other related agencies as TMDL studies that <br />impact Arden Hills are approved and implemented. <br /> <br /> <br /> <br /> <br /> <br />Dr <br />a <br />f <br />t <br /> <br />11 <br />/ <br />2 <br />0 <br />/ <br />2 <br />0 <br />1 <br />7
