Pollutant Source Control Measures
Source control measures are post-development best management practices (BMPs) that prevent pollutant generation, discharge and runoff by controlling it at its source or, at a minimum, limiting pollutant exposure to stormwater. Typically, a source control measure involves a cover, berm, drain connection to the sanitary sewer system or some other structural design element that prevents a pollutant from becoming a direct discharge to stormwater. Source control measures can also include operational BMPs, such as routine pavement sweeping, using a wet vactor to collect soapy washwater, or instituing a practice to immediately safely drain fluids from leaking vehicles. Both structural and operational source control BMPs can prevent pollutants from entering stormwater runoff.
As part of its "C.3. Stormwater Handbook" (Attachment III-1), the Program provides a list of Model Conditions of Approval for Stormwater Quality, which includes examples source control measures for development projects.
