Chapter 102 Erosion & Sedimentation Control
The District maintains a Level II delegation with the Department of Environmental Protection to handle Chapter 102 of the Pennsylvania Clean Streams Law for the County. This chapter details issues dealing with erosion and sedimentation control for earthmoving activities. The District reviews Erosion and Sedimentation (E&S) Control Plans for permitted (NPDES) and non-permitted earthmoving sites. The District also comments on the E&S plans for mining activities. (Please note that E&S plans for mining operations are kept on file in the District office and available for public review. We as a District reserve the right to comment on the adequacy of E&S plan elements but do not ultimately approve E&S plans associated with mining activities. For mining information contact the DEP Knox District office at (814) 797-1191.) Among other duties, the District is responsible for inspecting earthmoving sites for adequate E&S implementation. Permitted sites are inspected on a regular basis; while non-permitted sites are inspected only on a complaint basis. The District provides information and assistance to the public and also provides educational training programs to the regulated community.
Why E&S Control? PA Code Title 25 Chapter 102 Regulatory requirements in Pennsylvania require that any earthmoving activity implement Best Management Practices to minimize accelerated erosion during earth disturbances. Primarily, the purpose for implementation of E&S controls is to protect the physical, chemical and biological integrity of the watershed where the activity is located. How is E&S Control Implemented? Erosion control Best Management Practices, or 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. The implementation and proper utilization of BMPs are some of the key elements that make up an E&S control plan.
