Stormwater Management
In accordance with the Pennsylvania Department of Environmental Protection’s (DEP) National Pollutant Discharge Elimination System (NPDES) General Permit regulations, Easttown Township is required to develop and implement a stormwater management program. The program is based on the federal Municipal Separate Storm Sewer System (MS4) protocol (developed by DEP).
The DEP’s Protocols provide our township with suitable guidelines to design a local program that addresses the DEP’s six Best Management Practices (or BMPs), which are also known as "control measures." These six BMP’s are designed to reduce the discharge of pollutants from MS4s, to the maximum extent practicable, to protect water quality, and to satisfy the appropriate requirements of the Federal Clean Water Act. The six BMP categories are:
The federal regulations provide flexibility within these six categories of BMP’s.
- Public Education & Outreach Control Measure
- Public Participation & Involvement Control Measure
- Illicit discharge Detection & Elimination Control Measure
- Construction Site Stormwater Runoff Control Measure
- Post Construction Stormwater Management in New Development & Redevelopment Control Measure
- Pollution Prevention and Good Housekeeping for Municipal Operations & Maintenance Control Measure
