Environmental Review
Westway Expansion Projects

UPDATE   (8/20/2015)

The release of the draft Environmental Impact Statements for the Westway and Imperium expansion projects, and start of the public comment period will occur on Monday, Aug. 31, 2015.

The two Draft EISs will be released on this page. Along with the draft documents and chapters, there will also be fact sheets summarizing key issue areas, the environmental review process, and the Westway and Imperium expansion projects.

Public Comment

We are providing multiple ways to comment during the expanded 60-day comment period, starting Aug. 31, 2015, and ending Oct. 29, 2015.

Open houses and public hearings will be held on Oct. 1 in Elma, and Oct. 8 in Aberdeen. Additional details will be released Aug. 31 on the project website, as well as through the LISTSERV.

Public engagement is a vital part of the environmental review process, and we look forward to receiving your comments on the analysis and findings in the draft EISs.

Westway Terminal Company is proposing an expansion of a bulk liquid storage facility at the Port of Grays Harbor in Hoquiam. An environmental review is occurring for this proposal.

Co-lead Agencies Ecology and the city of Hoquiam have issued a Determination of Significance (DS) under the State Environmental Policy Act (SEPA). The DS identifies areas of study that will be examined during the environmental review.

The co-lead agencies are asking for the public’s input on these study items as well as other topics that should be evaluated during the environmental review. The comment period for the expanded scoping process is April 10 to May 27. The co-lead agencies will consider all comments. The co-lead agencies will decide what to study in the environmental review after the scoping period ends.

Project proposal

Westway proposes expanding its existing bulk liquid storage terminal to allow for the receipt of crude oil unit trains, storage of crude oil from these trains, and shipment of crude oil by vessel and/or barge from Port of Grays Harbor Terminal 1.

According to the project proposal, the Westway expansion project would be done in two phases. The information below includes the proposed construction and operations for both phases.

Five new storage tanks would be constructed on the site to the south of Westway’s existing bulk storage tanks. The new tanks would each have a capacity of 200,000 barrels (8.4 million gallons) for a project total storage capacity of 1 million barrels (42 million gallons). The annual maximum throughput would be 17.8 million barrels (749.9 million gallons) per year. The tanks would be surrounded by a concrete containment wall with the capacity to contain the total volume of a single tank plus an allowance for precipitation.

The existing rail facility on the site would be expanded from two short spurs with a total of 18 loading/unloading spots to four longer spurs with a total of 80 loading/unloading spots. The rail car containment area would have the capacity to contain the total volume of a single rail car plus an allowance for precipitation.

A new pipeline would connect the new tanks, via an existing pipeline bridge, to the Port’s Terminal 1. Work performed on the terminal dock would be limited to the addition of loading arms and parts of a marine vapor combustion system.

There would be no in-water work.

Construction of the expanded rail facility would involve demolition of an existing wood frame warehouse and construction of additional office space and support facilities.

The company estimates that terminal operations would handle 458 unit trains a year (loaded and empty) or 1.25 trains every day. The company estimates that the terminal operations would handle 99 to 119 barges a year (198 to 238 entry and departure transits) or approximately one every two days.

Existing Operations

Westway currently operates a methanol storage facility at the Port of Grays Harbor. The facility includes a tank area consisting of four storage tanks with a total of 13.4 million gallons of storage and a rail yard. The facility receives and ships methanol via train, truck and vessels. These existing operations will continue and are separate from the expansion proposal.
