DETERMINATION OF NONSIGNIFICANCE
Project Name: Port of Tacoma Pierce County Terminal (PCT) Maintenance Dredging Project
Description of proposal: The Port of Tacoma needs to perform maintenance dredging at the Pierce County
Terminal (PCT) facility located along the Blair Waterway in order to remove shoaling areas that are
preventing vessels from being fully loaded with cargo. “Light loading” vessels is causing economic impacts
and safety concerns. The proposed maintenance dredging will remove shoaling caused by propwash along
the berthing areas at Pierce County Terminal allowing the terminal operator to resume normal operations.
The purpose of the proposed pro-
ject is to restore the berthing areas at PCT to the permitted depth of -51
feet MLLW, with an incidental 2-foot over-dredge allowance. Maintenance dredging is needed to allow
normal operation at the terminals to resume. The current conditions do not allow for full vessel loading
(economic impact) and could lead to grounding out of vessels (safety issue). To achieve this purpose,
the Port must dredge up to 28,000 CY of sediments, of which up to roughly 13,000 CY is over dredge.
The proposed maintenance dredging is the minimum work needed to return the terminal to normal
