Description:This environmental assessment (EA) evaluates the potential environmental impacts associated with the United States (U.S.) Department of the Navy's (Navy's) Proposed Action to perform maintenance and restore the structural integrity of the Explosives Handling Wharf 1 (EHW-1) facility located at Naval Base (NAVBASE) Kitsap Bangor, WA. The Proposed Action includes demolishing four 24-inch hollow prestressed octagonal concrete piles and installing four 30-inch concrete filled steel piles adjacent to the demolished piles at Bent 27 of the outboard support of the EHW-1. Additionally, the project includes replacement of structural elements such as decking and pile caps, installation of cathodic protection, repair of a concrete wetwell, and recoating of the tops of fender piles and steel mooring fittings. As part of the Navy's mission, maintaining facilities and readiness is a priority. Since the action is to replace existing piles and conduct other maintenance, the only alternative would be to not perform maintenance and replace piles; therefore, no practical or feasible action alternatives were identified. This EA will analyze the Proposed Action and the No-Action alternative. The analysis addresses potential direct and indirect impacts on sediments, water quality, airborne noise, biological resources, cultural resources, American Indian traditional resources and cumulative impacts. There is no cooperating agency for this document.
