STORMWATER MANAGEMENT PROGRAM

The National Pollutant Discharge Elimination System (NPDES) permit program is a requirement of the federal Clean Water Act. The federal Environmental Protection Agency (EPA) has delegated permit authority to state environmental agencies. In Washington, the NPDES-delegated permit authority is the Washington State Department of Ecology (Ecology).

This document was prepared for the City of Sumner to meet the requirements for a Stormwater Management Program (SWMP) as required by the NPDES Phase II permit issued by Ecology. The SWMP was developed to outline the reduction of pollutant discharges from the City’s Municipal Separate Storm Sewer System (MS4).

The goal of this program is outline how the reduction of pollutant discharges to the maximum extent possible (MEP) will be accomplished as well as meet state All Known and Reasonable Treatment (AKART) requirements and protect water quality. This will be done through the application of Best Management Practices (BMP’s) throughout the major sections listed below:
• Public Education and Outreach
• Public Involvement and Participation
• Illicit Discharge Detection and Elimination
• Controlling Runoff from New Development, Redevelopment and Construction Sites
• Pollution Prevention and Operation and Maintenance for Municipal Operations
