The Stormwater Program for Municipal Separate Storm Sewer Systems (MS4s) is designed to reduce the amount of sediment and pollution that enters surface and ground water from storm sewer systems to the maximum extent practical. Stormwater discharges associated with MS4s are regulated through the use of National Pollutant Discharge Elimination Systems (NPDES) permits. NPDES permits are legal documents. Because the stormwater permit is a part of the NPDES program, the City of Rosemount must be aware of the national goals of restoring the integrity of the nation’s waters. The Minnesota Pollution Control Agency (MPCA) requires owners and operators of MS4 systems to complete and produce a SWPPP to the MPCA for review and approval. The MS4 owner or operator is required to submit an annual report with the activities completed for the subsequent year.
In response to this new legislation, the City of Rosemount has developed a Stormwater Pollution Prevention Plan (SWPPP) to address the issues associated with stormwater pollution. The plan is designed to prevent the spread of pollutants by applying Best Management Practices (BMPs) and Public Education which aim to reduce the concentration of common pollutants and eliminate the pollutant sources. The SWPPP is a collaboration of ordinance, policy and public education. The Surface Water Management Ordinance and Erosion Control Policy stipulate strict requirements relating to fertilizer application, wetland protection and erosion control application(s). Public education focuses on the lifestyle habits and practices of the community and identifies which habits and practices are influencing stormwater pollution. Efforts are focused on these particular issues.
