Alexander Avenue Petroleum Tank Facilities site. Dotted line shows approximate boundary.
The Alexander Avenue Petroleum Tank Facilities site is located at 709, 901, and a part of 1001 Alexander Avenue East in Tacoma. The cleanup site investigation will define more precisely the boundaries at the site.
 
Buildings for petroleum processing and storage had been on the site since the 1930s. The port bought the property in 1966 and Mariana Properties purchased some of the property in 2001.

In 1983, the port removed storage tanks from part of the property. The port later removed the crude oil plant from another part of the property. Buildings in a warehouse complex owned by the port still remain at 901 Alexander Avenue.

Initial studies showed that soil orgroundwater at the site are contaminated with petroleum-related contaminants including total petroleum hydrocarbons, carcinogenic polycyclic aromatic hydrocarbons, and benzene. Other contaminats found in soil or groundwater include lead, arsenic, copper, tetrachloroethylene (PCE), trichloroethylene (TCE), and vinyl chloride.

Current Status

In October 2013, Ecology entered into an agreed order with the Port of Tacoma (port) and Mariana Properties, Inc. (Mariana). This legal agreement requires the port and Mariana to do:

  • A remedial investigation—Defines the kind and extent of contamination.
  • A feasibility study— Evaluates at cleanup options.
  • Develop a draft Cleanup Action Plan—Describes the cleanup process. 

The remedial investigation is available for review. We will invite public comments on the remedial investigation along with the feasibility study, once it is complete.
