Port of Tacoma PUBLIC NOTICE DETERMINATION OF NONSIGNIFICANCE WAC 197-11-970 Project Name: Combined Breasting/ Mooring Dolphin Project Description of Proposal: The Project proposes to install three in-water dolphins (two to act as combined breasting and mooring dolphins, one strictly for mooring) southeast of Totem Ocean Trailer Express (TOTE) existing loading pier. A mooring bit and capstan structure are proposed for installation onshore and above the Mean Higher High Water (MHHW) mark. In-water Project Elements The three proposed breasting/ mooring dolphins will be constructed of up to 6 steel pipe piles (of a maximum diameter of about 20 inches each) and 3 steel or concrete fender piles (of a maximum diameter of about 16 inches each). The pile cap (top of each dolphin) will be approximately 12 feet long by 12 feet wide poured-in-place concrete. Shoreline/ Upland Project Elements The proposed upland capstan and mooring bit will be constructed of a pile-supported concrete cap (of approximate maximum dimensions of 15 feet wide by 13 feet long and about 3.5 to 6 feet deep). All concrete piles (approximately 21, up to about 14 inches in diameter) will be installed landward of the MHHW mark to support the mooring bit. This project is proposed to support direct liquefied natural gas (LNG) fueling of marine vessels that are being converted to LNG that already use and visit the TOTE facility. Specifically, the proposed structures will stabilize the fueling barge as it provides LNG to the vessel berthed at the existing pier. The location of the dolphins will allow fueling operations to move from their current location out board of the ship, which puts the barge 40 feet into the navigation channel, to a location aft of the ship nearer to the shore and away from vessels transiting the Blair Waterway. Each pile installed (only metal and concrete pile are proposed) will be mitigated with the removal of an equivalent area of creosote treated pile. Each square foot of new overwater coverage will be mitigated for by the removal of an equivalent square foot of existing creosote treated timber deck. The removal for mitigation will happen on either the Blair or Hylebos Waterways as part of Puget Sound Energy's proposed LNG plant. If that project does not go forward, TOTE has committed to removing the necessary pile and over-water coverage from Commencement Bay.
