National Pollutant Discharge Elimination Systems

(NPDES) Permits

Earth Disturbance activities that involve 1 acre or more over the life of the project require a NPDES Permit.  There are two types of NPDES Permits for stormwater discharges associated with construction activities:

  • Individual Permits are required for projects which take place within a Special Protection Watershed(PDF), such as streams classified in Chapter 93 or on the DEP Existing Use classification as High Quality (HQ) or Exceptional Value (EV). Exceptional Value Wetlands and streams classified as “Class A Wild Trout” by the PA Fish & Boat Commission may also be considered Special Protection Watersheds.
  • General Permits are required for all other projects which meet the NPDES permit criteria but do not fall under the Individual Permit Guidelines.
  • Erosion and Sediment Control General Permit (ESCGP-2) are required for oil and gas activities (exploration, processing, treatment operations or transmission lines) involving 5 or more acres of disturbance.
  • Erosion and Sediment Control Permit is required for Timber Harvesting or Road Maintenance activities that plan to have 25 acres or more of earth disturbance over the life of the project.

Please refer to the Fact Sheets linked to the permits above for more information or feel free to visit the Bureau of Clean Water and E&S Resources web pages for more information as well.

All NPDES Permits are to be submitted to the WCCD for initial processing.  General NPDES Permits are reviewed and approved in house.  For Individual NPDES Permits WCCD does an administrative review along with the Erosion and Sedimentation Control Plan review, but the PA Department of Environmental Protection’s Northwest Regional Office is responsible for final permit issuance.

It is a Pennsylvania Requirement that a pre-application meeting be scheduled for ALL NPDES Permits.
