Stormwater runoff is one of the biggest impediments to surface water quality in Apple Valley. Under the federal Clean Water Act, cities must implement management practices to reduce the risk of pollution entering waterbodies through a stormwater system. The Minnesota Pollution Control Agency oversees and administers a permit program on behalf of the US Environmental Protection Agency that regulates these management practices to ensure that federal and state requirements are being met. The Apple Valley Stormwater Pollution Prevention Program lays out the management practices the City employs to address pollution within its stormwater system and to meet regulatory requirements.
Nondegradation Review As a part of the 2006 NPDES Permit for Municipal Separate Storm Sewer Systems issued by the Minnesota Pollution Control Agency, 30 cities were required to determine if there had been degradation to surface waters resulting from operation of their storm sewer systems since 1988 and whether degradation could be expected by the year 2020. The Nondegradation Reviewdetails Apple Valley's findings.
