This notice finalizes the reissuance of the Department of the Army Delaware State Programmatic General Permit-20 (SPGP-20), initially issued on March 23, 1984. This general permit authorizes certain existing and proposed piers, docks, mooring piles, boat lifts, breakwaters, and the replacement of existing serviceable bulkhead structures in navigable waters of the United States within the geographic boundaries of the Philadelphia District Corps of Engineers in the State of Delaware. This general permit has been developed for certain clearly described categories of minor projects involving structures and fill that require Department of the Army and State of Delaware authorizations. The reissuance and modification of SPGP-20 was coordinated with other interested Federal agencies, the State of Delaware, and the general public. The reissuance of SPGP-20 includes minor language changes and additional conditions to address the EFH provisions of Magnuson Stevens Act, EPA comments and National Park Service comments. The full text of the reauthorization of SPGP-20 is in the notice and General Permit.
