The Department of Natural Resources and Environmental Control (Division of Water and Division of Climate, Coastal and Energy) hereby provides a 20-day public notice of the water quality certification and the federal consistency determination submissions which have been received from the U.S. Army Corps of Engineers Philadelphia District (USACE).

The USACE 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. Activities typically authorized by this general permit include work and structures, such as bulkheads, breakwaters, piers, docks, pilings, rip rap, dredging and filling, etc., in substantially developed artificial tidal lagoons and their access channels. As part of this reauthorization, the maximum cubic yards of material authorized to be dredged from shoals has been increased from 300 cubic yards to 500 cubic yards to align with other state’s program general permits.
