NPDES Permits for Stormwater Discharges Associated with Construction Activities
NPDES (National Pollutant Discharge Elimination System) permits are required for construction sites equal or larger than one acre (equal to or greater than one acre of earth disturbance). The permit must be in to hand before earthwork begins. The requirements for an NPDES permit are defined by Federal and State regulations.
NPDES permits are “Individual” (issued by Pennsylvania Department of Environmental Protection [DEP] or "General" (PAG-02, authorized by delegated County Conservation District). The current version (PAG-02 effective Dec. 8, 2019) of the General NPDES permit will expire on December 7, 2024 regardless of when authorized; while Individual NPDES permits continue to expire 5 years from date of issuance.
Individual NPDES permits are for projects located in drainage basins listed Designated or Existing Use as "High Quality" or "Exceptional Value," (Special Protection) whereas projects within other drainage basins can qualify for a General NPDES permit in most situations. Official designations of drainage basins and streams are listed in the Pennsylvania Code. DEP’s eMapPA website provides approximate "High Quality" and "Exceptional Value" watershed locations.
A NPDES permit Notice of Intent (NOI, for General Permits) or Application (for Individual Permits) consists of several forms, PNDI receipt, erosion control (E&S) plan drawings, post construction stormwater management (PCSM) plan drawings, appropriate modules, and fees. The forms can be obtained from DEP or the Conservation District office. The required components of an NPDES permit application or NOI are listed in its appropriate checklist- and submitted with your NPDES permit application and/or NOI package.
Checks associated with NPDES permits are to different "payees" depending on the fee.
