Honolulu District Regulatory Office
Published Dec. 8, 2022
Expiration date: 1/9/2023

Interested parties are hereby notified that an application has been received by the U.S. Army Corps of Engineers, Honolulu District requesting Department of the Army (DA) authorization for the U.S. Navy’s proposed Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY & IMF) Dry Dock and Waterfront Production Facility project. The U.S. Navy is proposing to replace the existing Dry Dock 3 (DD3) and associated facilities with a new graving dry dock and waterfront production facility capable of servicing newer, larger fast-attack submarines in the Pacific Island Region. The new Dry Dock 5 would provide appropriate capability at PHNSY & IMF to meet the U.S. Navy’s submarine depot maintenance mission requirements and ensure a properly sized and configured waterfront production facility to enable efficient submarine maintenance.  

APPLICANT: U.S. Navy, Captain Mark D. Sohaney, Joint Base Pearl Harbor Hickam, 850 Ticonderoga Street, Suite 100, Pearl Harbor, HI  96860

LOCATION:  Various locations at the U.S. Navy, Joint Base Pearl Harbor-Hickam (JBPHH), including the Pearl Harbor Naval Shipyard Dry Docks, Waipio Peninsula, Pearl City Peninsula, Ford Island, Bishop Point, Loko Paaiau Fishpond at McGrew Point, and the South Oahu Ocean Dredged Material Disposal Site (SOODMDS) offshore of the Island of Oahu, Hawaii.

PROPOSED ACTIVITY:  The applicant proposes to conduct dredging, including transporting dredged material for ocean disposal; and removing structures and installing new structures in navigable waters of the U.S. The applicant also proposes to discharge dredged and fill material into waters of the U.S. for the construction of a new dry dock and waterfront production facility.  Ongoing operations and maintenance would include periodic dredging at the proposed channel approach. The applicant further proposes to install compensatory mitigation measures to offset unavoidable adverse impacts to waters of the U.S. resulting from the proposed dry dock project.  The implementation of the applicant’s proposed mitigation activities would involve dredging in navigable waters of the U.S. and the discharge of fill material into waters of the U.S. to restore and enhance aquatic ecosystems.  

AUTHORITY(S):  The proposed work is being evaluated under Section 404 of the Clean Water Act (33 USC 1344), Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403), and Section 103 of the Marine Protection, Research and Sanctuaries Act (33 USC 1413).
