About Our Program

The 1987 amendments to the Clean Water Act (CWA) added Section 402(p), which requires the U.S. Environmental Protection Agency (EPA) to develop a comprehensive phased program to regulate storm water quality discharges under the National Pollutant Discharge Elimination System (NPDES) program. In November of 1990, Phase I of the NPDES program was issued addressing storm water discharges from separate municipal storm sewer systems (MS4s) serving populations over 100,000 and industrial activities including discharges from construction activities disturbing five acres or more.

On December 8, 1999, the EPA published the NPDES Phase II regulations in the Federal Register as required by Section 402(p) of the CWA. NPDES Phase II regulations require small MS4s, those serving a population of less than 100,000 and located in an urbanized area, to obtain a municipal storm water permit. The State was designated as administrator of the NPDES permit. As such, the State created a general permit that applies to all MS4s in California. This permit is called the Waste Discharge Requirements for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems or the General Permit. This permit required each MS4 to develop a Stormwater Management Program (SWMP) that outlines six minimum control measures that each MS4 must implement to the technology-based standard of "maximum extent practicable". These measures are as follows:

  • Public Education - inform the public, businesses and industry about stormwater, the impacts of stormwater pollution on local waterways
  • Public Involvement - provide the community with opportunities to get involved in the stormwater program
  • Illicit Discharge Detection and Elimination - identify and eliminate illicit stormwater discharges and connections
  • Construction Stormwater Runoff - reduce pollutants in stormwater runoff and eliminate non-stormwater discharges from construction activities
  • New Development and Redevelopment - lessen the long-term impacts of stormwater discharges from urban development and redevelopment
  • Municipal Operations - implement good housekeeping measure to reduce pollutants from municipal activities

On August 7, 2002, the Roseville City Council authorized establishment of a Citizens Advisory Committee. This committee provided recommendations to Council regarding the City’s overall Storm Water Management Program (SWMP) strategy. Specifically, the committee provided input to the selection of best management practices to be implemented under each minimum control measure of the SWMP and reviewed funding options for the program.

In compliance with State requirements, Roseville’s SWMP was submitted to the State’s Central Valley Regional Water Quality Control Board (Region 5) on March 3, 2003 for their review and comment. Regional Board staff made comment to the SWMP. Those comments were incorporated and the revised SWMP was submitted for their approval. To comply federally adjudicated mandates, the SWMP was posted for thirty days on the State Water Resources Control Board’s website to receive public comment. No public comments were received during the review period and the City was granted permit coverage on July 2004.

The City is now in the implementation phase of the program. The permit term, based on a fiscal calendar, is five years. Each best management practice (BMP) is assigned an implementation year and full implementation of the SWMP will not be achieved until 2009. The City is required to submit an annual report delineating its progress for each BMP. Click the links below to view each annual report:
