Draft Environmental Assessment Public Review



Draft Environmental Assessment for Proposed Power Distribution System at Indian Island Available for Public Review


PORT HADLOCK, Wash – The U.S. Navy has prepared a Draft Environmental Assessment (EA) to evaluate the potential environmental effects associated with the Navy’s proposal to construct a looped power distribution system to the ammunition wharf on Naval Magazine (NAVMAG) Indian Island.

The purpose of the Proposed Action is to supply permanent shore-based power to submarines while they are berthed at the NAVMAG Indian Island during ordnance handling operations.

The Draft EA is available for public review online at http://go.usa.gov/tAr4. The Navy invites you to comment on the draft analysis.

The Navy is accepting written comments throughout the comment period, from Aug. 12, 2015, to Sept. 11, 2015. All written comments must be received by Sept. 11, 2015, to be considered by the Navy as it prepares the Final EA.  Comments may be sent by email to NWNEPA@navy.mil or by mail to:

Currently, submarines using the ammunition wharf receive power from two diesel-powered generators located on the shore adjacent to the ammunition wharf. The Proposed Action is needed because the Navy’s Clean Air Act permit for two existing diesel-powered generators had a condition that the generators be removed as the primary source of electricity at the Ammunition Wharf.

The Draft EA analyzes the potential environmental effects from the implementation of three action alternatives and a No Action Alternative. Under Alternative 1 (Preferred Alternative), the Navy would construct a new power distribution system by installing new power poles and new overhead distribution lines along existing roads and replacing an existing electrical substation on the ammunition wharf. Once the new system became operational, the Navy would remove the existing diesel generators and supporting equipment.  

Under Alternative 2, the Navy would install new underground distribution lines and remove the existing generators and equipment. Under Alternative 3, the Navy would purchase and install new permanent generators at the Ammunition Wharf. 

Under the No Action Alternative, the Navy would continue to operate the existing generators to provide power to submarines using the Ammunition Wharf until September 30, 2016. After September 30, 2016, the Ammunition Wharf would no longer provide power to submarines berthed at the Ammunition Wharf. The No Action Alternative would not meet the purpose of and need for the Proposed Action, but is carried forward as a baseline for the analysis in the Draft EA.
