Stormwater Management Program
To address polluted stormwater, the EPA has developed the National Pollutant Discharge Elimination System (NPDES). NPDES attempts to reduce polluted stormwater runoff by requiring operators of municipal separate storm sewer systems (MS4s) to implement best management practices to prevent contaminants from reaching our streams via stormwater runoff.
The East Salem Service District and areas near the Salem Urban Growth Boundary (UGB) are considered small MS4s, meaning Marion County must comply with the NPDES Phase II permit.
Under the Phase II permit, the county must develop and execute programs designed to decrease stormwater pollution, under these areas:
-Public Education & Outreach
-Public Participation & Involvement
-Illicit Discharge Detection & Elimination
-Construction Site Runoff Control
-Post Construction Runoff Control
-Pollution Prevention & Good Housekeeping
Our goal at Marion County is to develop a cost-effective, environmentally sound, and well engineered Stormwater Management Plan that is accepted by DEQ, the public, our Board of Commissioners, and county staff.
This Plan must comply with requirements of NPDES Phase II regulations and be compatible with surrounding jurisdictions.
