Dear Captain Dawson:
This letter is written in regard to your proposal to perform mechanical maintenance dredging of the existing naval reserve basin and access channel. A maximum of 96,611 cubic yards of materials are to be dredged from 16.6 acres of basin and access channel bottom to a design depth of 30 feet below mean lower low water with 2 foot allowance of over-dredging. This project is located in the Philadelphia Naval Reserve Basin (a.k.a. the Philadelphia Navy Yard), in the City of Philadelphia, Pennsylvania. Dredged materials are to be disposed at either the Weeks Marine White’s Basin Rehandling Facility (Logan township, Gloucester County, New Jersey) or the Biles Island disposal facility (Morrisville, Falls Township, Bucks County, Pennsylvania). Based upon our review of the information that has been provided, it has been determined that the proposed work is authorized by Department of the Army Nationwide Permit (NWP) 35 Marina Basin Maintenance Dredging pursuant to Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403).
This verification of authorization under NWP 35, described in the Federal Register at 91 FR 768, is based on your agreement to comply with the general conditions, regional conditions and project specific special conditions listed in this letter. Additionally, this approval is conditioned upon compliance with the regional conditions as described in the link below.
