PA Code Title 25 Chapter 102 Regulatory requirements in
The primary purpose for implementation of E&S and PCSM BMPs are to protect the physical, chemical and biological integrity of the watershed where the activity is located. The design and installation of the E&S and PCSM BMPs are a part of the permit issued for the site.
E&S BMPs are activities, facilities, measures or procedures implemented on a site that aid in minimizing the potential for discharge of sediment to waterways of the Commonwealth. Conversely, PCSM BMPs infiltrate stormwater, provide retention/detention and improve the water quality after the site work is completed.
Inquiries regarding BMP implementation should be directed to the Districtís technical staff.
