NPDES Annual Report
NPDES Program Background
National Pollutant Discharge Elimination System (NPDES) is a program created in 1990 by the United States Environmental Protection Agency (EPA) under the Clean Water Act to protect water quality through the regulation of the discharge of pollutants to lakes, streams, wetlands and other surface waters. The Minnesota Pollution Control Agency (MPCA) is the local authority responsible for administering this program. Under this program, NPDES permits are issued to regulate different types of municipal, construction and industrial activities.
The MPCA issued the current Municipal Separate Storm Sewer System (MS4) NPDES Phase I Permit to the City of Minneapolis and the Minneapolis Park & Recreation Board (MPRB) as co-permittees on January 21, 2011. The primary goal of the MS4 permit is to restore and maintain the chemical, physical and biological integrity of waters of the state through management and treatment of urban stormwater runoff.
As a municipality with a population greater than 100,000, Minneapolis is permitted under federal requirements as a Phase I MS4 community. As required by the 2011 permit, the City and the MPRB prepared a new Stormwater Management Program,which was approved by the MPCA in 2013. The City's program endeavors to protect people, property and the environment, to meet or surpass regulatory requirements, to maintain and enhance infrastructure, to provide cost-effective services, to educate and engage the public and stakeholders, and to enhance livability and safety. The Stormwater Management Program was last updated in July 2015.
