PORT OF SEATTLE TERMINAL 91
2001 W Garfield St, Seattle, WA 98119

PUBLIC COMMENT PERIOD PERIODIC REVEIW NOW CLOSED

Ecology will oversee an investigation of contamination in the Submerged Lands Area of the Port of Seattle Terminal 91 (T-91) facility located at the north end of Elliott Bay at 2001 West Garfield Street Seattle, Washington.  In order to find out where the contamination is located we need a legal agreement with the Port of Seattle (Port). Hazardous wastes were once treated, stored and disposed of on this site, so they also need a Corrective Action Permit to continue the cleanup. The current permit expires in 2020.

The comment period is closed. No more comments will be accepted, however you can still review the documents.

Draft Agreed Order: Legal agreement to ensure that a remedial investigation (RI) to determine the location and type of the contamination meets the requirements of the state cleanup law.

Public Participation Plan:  Creates a process to communicate with and receive feedback from the public about this cleanup.

Corrective Action Permit and Application:  Permit that requires the Port to continue cleanup.


You can find out more about the cleanup December 4, 2019

Ecology staff will make a short presentation about the cleanup

Queen Anne Community Council meeting
7:30pm on Wednesday
100 Crockett St. (Queen Anne Manor)

Meetings take place in the basement, accessible by walking down to the end of the hallway and taking the elevator down to the basement.

What happens next?

Ecology will consider all comments and may amend the documents based on your comments.  We will finalize the agreed order and the Port will start the remedial investigation (RI).  Results from the RI will determine if more cleanup is needed.

SITE BACKGROUND

The Terminal 91 Complex (T91 Complex) is located in an industrial area in the Interbay neighborhood of Seattle. Various railroads, land development companies, and private individuals owned the property from the late 1800s through 1920. The Great Northern Railroad began to develop the area in the early 1900s by filling in the area between Magnolia Bluff and Queen Anne Hill. Filling continued through the 1940's.
 
The T91 Complex was operated by several oil companies from 1926 until 1941, when the U.S. Navy took possession. The Port purchased the facility in the 1970s. A four-acre parcel of the T91 Complex is the site of a former tank farm. Constructed in the 1920s, it operated as a fuel storage facility until it was demolished in 2005. In 1992, the owner of the tank farm, Burlington Environmental Inc. (BEI), was issued a permit to operate as a dangerous waste treatment and storage facility (TSD). Although the permit is no longer active, the Port is responsible for cleanup of contamination at the site.



Activities conducted on-site include:

  • Storage of fuel and waste oil.
  • Blending and storage of marine boiler fuel, diesel, and other petroleum products. 
  • Treatment of wastewater from oil and coolant emulsions, industrial wastewater, and sludge.
  • Treatment of bilge and ballast waters.


SITE CONTAMINATION AND PAST CLEANUPS

Submerged lands (sediments at the bottom of Elliot Bay): The Army Corps of Engineers (Corps) started cleaning up the marine sediments under the water in 2010 when discarded military munitions were discovered near T-90 and T-91. The Corps first investigated to locate the discarded munitions.  They removed munitions in 2012.

When the Navy owned the facility, they sometimes disposed of munitions overboard without documentation while ships were in port. Occasionally law enforcement divers still find and remove munitions.

Historic land use and industrial practices also contaminated the sediments with chemicals and metals. Contaminants there include:

• Metals – arsenic, cadmium, chromium, copper, lead, mercury, silver, and zinc
• Tributyltin
• Poly Aromatic Hydrocarbons (PAHs)
• Phthalates
• Semi volatile organic compounds (SVOCs)
• Poly chlorinated biphenyls (PCBs)

This comment period from October 10 - November 25, 2019 is for a new agreed order between the Port and Ecology to look for contamination in the submerged lands. The Port conducted preliminary investigations in 2012  and 2018.  

Tank Farm: The Port removed above ground tanks and contaminated structures in 2014.  Under a restrictive covenant, the Port can only use the land in ways that prevent people from coming in contact with any remaining hazardous substances. Philip Services Corp. operated the former tank farm as a TSD. Other Port tenants used those same tanks for fuel storage and distribution.

Uplands: The Port cleaned up the remainder of the upland areas, other than the Tank Farm Area beginning in 1999. Soil in these areas was contaminated mostly with petroleum products.
