PUBLIC NOTICE DETERMINATION OF NONSIGNIFICANCEWAC 197-11-970 Project Name: Georgia-Pacific Tacoma Marine Terminal Upgrade Description of proposal: The proposed project will have two phases. Phase 1 will repair and replace components of an existing dock facility. Components include replacing three berthing dolphins, replacing dock fenders, replacing and relocating catwalks, relocating a conveyer system and rock off-loading hoppers, and expanding a rock storage building. Eighty-three 15-inch creosote-treated timber piles will be removed and replaced with 55 24-inch steel piles for the replacement of the dolphins, dock fenders and catwalk replacements. The existing timber catwalks will be replaced with 60% open space grated catwalks, and the overwater footprint will decrease by approximately 100 square feet. Shore bollards will be replaced and relocated to accommodate the shift of rock delivery ships to the southeast. Expansion of a rock storage building will increase storage capacity from 29,500 metric tons to 54,000 metric tons; however, no change to the building height or impervious surface due to the building expansion is anticipated. Phase 2 of the project involves dredging the berthing area from -31.0 feet mean lower low water (MLLW) to -45.0 feet MLLW to allow existing ships to utilize unused capacity to offload more material at one time. Dredging is anticipated to remove approximately 28,000 cubic yards of material to accommodate the increased vessel draft.
