About Our Program

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

Stormwater Management Program 2004

FedEPA published the NPDES Phase II regulations in the Federal Register as required by Section 402(p) of the CWA in 1999. 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 program by FedEPA. In response, the State adopted a general permit for all MS4s in California. This General Permit (No. CAS000004) was revised and adopted in February 2013. It specifies the requirements and best management practices (BMPs) that each Phase II MS4 must implement to the technology-based standard of "maximum extent practicable" (MEP). These requirements are as follows:

  • Program Management Element – defines the legal authority, enforcement powers, and certification statement  required of the MS4.
  • Education Outreach Program - inform the public, businesses, industry and city staff about stormwater, the impacts of stormwater pollution on local waterways. 
  • Public Involvement and Participation Program - provide the community with opportunities to get involved and participate  in the stormwater program. 
  • Illicit Discharge Detection and Elimination - identify and eliminate illicit stormwater discharges and connections.
  • Construction Site Stormwater Runoff Control Program - reduce pollutants in stormwater runoff and eliminate non-stormwater discharges from construction activities.
  • Pollution Prevention / Good Housekeeping - implement good housekeeping measures to reduce pollutants from municipal activities.
  • Post Construction Stormwater Management Program - lessen the long-term impacts of stormwater discharges from urban development and redevelopment.  
  • Water Quality Monitoring – sample and analyze receiving water for compliance with water quality objectives as specified by the Statewide Water Quality Control Plan, the California Toxics Rule, and the Regional Water Board Basin Plan.
  • Program Effectiveness Assessment and Improvement – track the annual and long-term effectiveness of the Stormwater Program Best Management Practices (BMPs) in meeting water quality objectives.
  • Total Maximum Daily Loads Compliance Requirements – meet waste load allocations, effluent limitations, implementation requirements and monitoring requirements as specified in the Regional Water Board Basin Plan.
  • Annual Reporting Program – submit a summary of the past year’s activities for each program element and certify compliance with all permit requirements using the State Water Resources Control Board ‘s electronic database Storm Water Multiple Application and Report Tracking System (SMARTS). 

Under the General Permit requirements of 2003, Roseville’s submitted a Stormwater Management Plan (SWMP) to the State’s Central Valley Regional Water Quality Control Board (Region 5) for 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. This SWMP remained in effect until July 2013.

The City is now held to the provisions for the new General Permit as listed in the Guidance Document submitted to the State Board on July 2004. Each permit reporting period is based on the fiscal year (July 1 - June 30), with a total permit term of five years. Each BMP is assigned an implementation year and full implementation of the permit will be achieved in 2018. The City is required to submit an annual report delineating our progress for each year. Click the links below to view each annual report for years 2004 - 2012. Future reports may be viewed on the SMARTS website.
