Construction Stormwater

 

** IMPORTANT NEWS ** – The PAG-02 NPDES General Permit for Stormwater Discharges Associated with Construction Activities expires on December 7, 2017. DEP is administratively extending PAG-02 until December 7, 2018. Notice of the extension is published in the October 21, 2017 edition of the Pennsylvania Bulletin. Persons that are operating under the PAG-02 General Permit may continue to operate until December 7, 2018 or the expiration date of coverage identified on the permit coverage approval page, whichever is later. DEP is extending the availability of this permit to adequately complete preparation of the renewal of the PAG-02 General Permit. DEP expects to reissue the General Permit prior to December 7, 2018. From December 8, 2017 until a final, renewed PAG-02 General Permit becomes effective, DEP and county conservation districts that are delegated to issue NPDES permits will be unable to approve General Permit coverage for new projects. During this time the only available mechanism for NPDES permit coverage for new stormwater discharges associated with construction activities will be individual NPDES permits.

Please see the Frequently Asked Questions (FAQ) on the PAG-02 Administrative Extension.

 

The Bureau of Clean Water administers the statewide Erosion and Sediment Control (E&S) program under 25 Pa. Code Chapter 102. Chapter 102 requires a permit from DEP for the following activities:

  • Construction activities with earth disturbances greater than or equal to one acre, not including agricultural plowing or tilling, animal heavy use areas, timber harvesting activities or road maintenance activities, which require National Pollutant Discharge Elimination System (NPDES) permit coverage. If eligible, persons disturbing one or more acres may apply for coverage under the PAG-02 NPDES General Permit for Stormwater Discharges Associated with Construction Activities. If ineligible for PAG-02 coverage, persons may apply for an individual NPDES permit.

  • Timber harvesting and road maintenance activities involving 25 or more acres of earth disturbance. An E&S permit is required under Pennsylvania's Clean Streams Law for these activities, rather than an NPDES permit.

  • Oil and gas activities (e.g., exploration, production, processing, treatment operations or transmission facilities) involving 5 or more acres of earth disturbance. An E&S permit is required under Pennsylvania's Clean Streams Law for these activities. If eligible, persons conducting these activities may submit a Notice of Intent (NOI) for coverage under the E&S General Permit (ESCGP-2).

  • Other activities involving 5 or more acres of earth disturbance not identified above require an E&S permit.
