In 2003, Lower Pottsgrove Township became a Small Municipal Separate Storm Sewer System (MS4) under the Pennsylvania Department of Environmental Protections (DEP) National Pollutant Discharge Elimination System (NPDES) General Permit regulations. Chapter 203: Stormwater Management Ordinance
The Township was required to develop and implement a storm water management program by its MS4 permit, which is based on the federal MS4 regulations. The MS4 Permit requires the Township to agree to implement the requirements of the MS4 protocol (developed by DEP).
The DEPs Protocols provide our township with suitable guidelines to design a local program that addresses the DEPs six Best Management Practices (or BMPs), which are also known as "control measures." These six BMPs 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:
•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
The federal regulations provide flexibility within these six categories of BMPs.
