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 using the Individual NPDES Permit Application for Discharges of Stormwater Associated with Construction Activities.
IMPORTANT NOTICE – The PAG-02 General Permit has been reissued by DEP, effective December 8, 2019. Permittees with existing coverage under the PAG-02 General Permit can use the link provided below to acknowledge their eligibility status for the reissued PAG-02 by March 9, 2020.
