Municipal Separate Storm Sewer System Discharge Permits and Annual Reports

The City of Salem operates under a National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Permit in order to release stormwater runoff from the stormwater system directly to our local streams.

The NPDES Permit requires the City to perform water quality monitoring in the storm system and in our streams, to complete a variety of assessments and deliverables, and to submit an annual report to the Oregon Department of Environmental Quality every fall.

Programs in the Stormwater Management Plan

The Stormwater Master Plan addresses stormwater quantity and quality in a manner that is compatible with the NPDES Permit.

The National Pollutant Discharge Elimination System Permit is a requirement of the federal Clean Water Act, and it requires the City of Salem to implement a Stormwater Management Plan approved by the Oregon Department of Environmental Quality.

Programs in the Stormwater Management Plan include programs for:

  • Illegal dumping control
  • Illicit discharge detection and elimination
  • Industrial stormwater discharge
  • Stormwater monitoring
  • Operations and maintenance
  • Public education, outreach, and participation
  • Spill prevention and response
