Naval Shipyard Infrastructure Optimization
National Historic Preservation Act Consultation


The Navy is consulting to develop a Nationwide Programmatic Agreement (NPA) that will adapt strong, proactive, and innovative historic preservation planning to the unique challenges associated with optimizing ship-maintenance capabilities at the Naval Shipyards, consistent with Sections 106 and 110 of the the National Historic Preservation Act (54 U.S.C. §§ 306107 and 306108) and implementing regulations 36 CFR 800.

The Navy established the Shipyard Infrastructure Optimization Program (SIOP) pursuant to the 2018 National Defense Authorization Act, which requires the Navy to address critical shortfalls in ship maintenance performance, and to develop a shipyard infrastructure strategy and plan to strengthen the Navy’s capability to maintain its nuclear-powered vessels. The Naval Shipyards are essential components of our national defense that directly support Navy operations by providing critical overhaul and maintenance of aircraft carriers and submarines. Currently, SIOP planning focuses on the main maintenance sites where nuclear-powered vessel maintenance is performed: Norfolk Naval Shipyard (NNSY), Virginia; Pearl Harbor Naval Shipyard (PHNSY), Hawaii; Portsmouth Naval Shipyard (PNSY), Maine; and Puget Sound Naval Shipyard (PSNS), Washington. As development continues over SIOP’s projected 20-year program, the Navy anticipates that additional shipyard support areas will require optimization.

In support of SIOP, the Navy proposes to develop the NPA to incorporate comprehensive historic preservation planning with this complex planning and investment process. The Navy plans to consult on the development of the NPA with the Advisory Council on Historic Preservation; the National Conference of State Historic Preservation Officers; the National Park Service; State Historic Preservation Officers for Hawaii, Maine, Virginia, and Washington; Native Hawaiian Organizations and Indian Tribes; interested historic preservation organizations; and the public.
