I. Introduction History The Clean Water Act was enacted in 1972 to regulate discharges of pollutants into the surface waters of the United States. Water quality standards were set for all contaminants in surface waters. In 1987, the Clean Water Act was amended to require implementation of a two-phase comprehensive national program to address storm water runoff. Phase I of the National Pollutant Discharge Elimination. System (NPDES) program regulated large construction sites, 10 categories of industrial facilities, and major metropolitan municipalities with populations greater than 100,000 (such as Minneapolis and Saint Paul). Implementation of Phase II in 1999 broadened the program to include smaller construction sites, municipally owned or operated industrial activity, and many more municipalities. The Environmental Protection Agency (EPA) delegated regulation of the Clean Water Act to the Minnesota Pollution Control Agency (MPCA). Permit Goals The MPCA has identified the goals of this permit to restore and maintain the chemical, physical, and biological integrity of waters of the state through management and treatment of urban storm water runoff. This is accomplished by requiring the preparation of a Storm Water Pollution Prevention Program (SWPPP) from Municipal Separate Storm Sewer Systems (MS4). Permit Coverage The City of Roseville has prepared the following permit in accordance with the MPCA. This permit authorizes discharges of storm water from Small Municipal Separate Storm Sewer Systems (MS4) as defined in 40 CFR 122.26 (b) (16). The City understands the limitations to the permit as listed in Part II, Section B of the General Permit. Permit Requirements As a part of the NPDES Phase II permit, the City of Roseville is required to develop and implement a Storm Water Pollution Prevention Program (SWPPP) to reduce the discharge of pollutants from their storm sewer system to the maximum extent practicable. The SWPPP must cover the following six minimum control measures: ® Public education and outreach; • Public participation/involvement; • Illicit discharge, detection and elimination; • Construction site runoff control; • Post-construction site runoff control; and ® Pollution prevention good housekeeping. The SWPPP must identify best management practices (BMPs) and measurable goals associated with each minimum control measure. BMP summary sheets are located in the next section of this report, which describe each BMP and steps for implementation in more detail. An annual report on the implementation of the SWPPP must be submitted each year. wq-strm4-50
