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 Although the permit is no longer active, the Port is responsible for cleanup of contamination at the site.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

Hazardous substances were released to soil and groundwater from aboveground storage tanks, fuel distribution piping systems, and other activities associated with historical operations at the Site.  

Contaminants at this site include:

  • Petroleum products
  • Volatile organic compounds
  • Semi-volatile organic compounds
  • Metals
  • Polychlorinated biphenyls (PCBs)
  • Discarded military munitions


CLEANUP

Tank Farm
After the dangerous waste permit was closed, the cleanup process started under a closure plan approved by Ecology in 2003. All of the above-ground tanks and facilities were removed in 2005. Further investigation and cleanup plan selection, design, planning, and permitting were conducted for the contaminated soil and groundwater from 2005 to 2013. The cleanup action plan was implemented in 2014 and 2015.

Future Cleanup Projects
The Port is also required to address potential contamination of the sediments in the areas near Piers 90 and 91.  Further sampling and analysis is needed to determine the extent of contamination, and what remedies will be needed to protect human health and the environment.
