NPDES and LAS General Permits

In addition to individual permits, EPD has identified several types of dischargers that have similar operational and effluent characteristics. Rather than each facility receive an individual permit, general permits serve as an “umbrella” permit under which anyone who meets the specific eligibility criteria may apply to receive coverage. General permits exist for both NPDES and LAS, public and private facilities.

New or expanding facilities should be advised that they may be required to submit additional documentation with their NOI, including but not limited to a Design Development Report. All new or expanding facilities requesting coverage under a NPDES general permit must additionally submit an Anti-degradation Analysis for review and approval. The associated Anti-degradation Analysis forms for both domestic and industrial wastewater facilities may be found here. Please carefully review the applicable permit and any associated guidance for information on additional requirements.

Below is a list of the current effective general permits offered by EPD. Basic information may be found at each of the corresponding links. Once you have identified a permit under which you would like to receive coverage, all associated documents, forms, and guidance may be found here.   

While not listed above, Storm Water general permits may be found here.

Facilities that intend to terminate their coverage must complete the Notice of Termination, which may be found here.
