The United States Army Corps of Engineers Philadelphia District, proposes to revalidate and extend the expiration date of the Department of the Army State Programmatic General Permit 18 from December 31, 2022 until December 31, 2027. This general permit, NAP-OPR-SPGP18, was last revalidated and extended in December of 2017 with an expiration date of December 31, 2022. This general permit has been developed for certain categories of structures and work and the discharge of dredged and fill material in waters of the U.S. that require Department of the Army and State of Delaware authorizations.

The re-validation and extension of General Permit SPGP 18 is being coordinated with other interested Federal agencies, the State of Delaware and the general public.
