A federal regulation that works in conjunction with the local E&S program is the National Pollution Discharge Elimination System (NPDES) Program. This regulation, the implementation of which has been delegated to DEP, requires any earthmoving activities disturbing one acre to obtain a permit. It is recommended that anyone disturbing one acre or greater of land during the life of an earthmoving project must contact the Conservation District to obtain a NPDES Permit.
Under the requirements of the NPDES program, these activities must have an approved erosion control plan. Perry County Conservation District conducts the reviews of these plans for DEP to assure compliance with Chapter 102 and the Clean Streams Law. The NPDES permit program also requires a Post Construction Stormwater Management (PCSM) Plan to address concerns about ground water recharge and water quality issues, especially during the more frequent storm events.
NPDES Permit applications are available on DEP's website at www.dep.state.pa.us. under the keyword “NPDES Permits”. Choose “Stormwater Construction Activities”
