The Unocal Bulk Plant site is an open field, south of Marine Drive.

The Unocal Bulk Plant #0601 is located at 738 West Marine Drive in Port Angeles. The bulk fuel plant contained underground and aboveground storage tanks, and equipment for dispensing petroleum and loading trucks. The bulk plant was dismantled and the site is now an open area.

During an inspection of the site in 1984, Ecology found leaks in diesel and gasoline distribution lines. Monitoring wells were put in to check for contamination. Free floating petroleum was found in the groundwater. The petroleum leaks polluted soil and groundwater at the site. 

Site Investigation And Cleanup

In interim actions, Chevron removed some free product from groundwater using an infiltration gallery. When the infiltration gallery was disassembled, the surrounding contaminated soil was also removed.   

Ecology and Chevron are working under Agreed Order DE 4086 to investigate contamination and compare options for cleaning up the contamination. Chevron has completed several supplemental investigations to determine the type and extent of contamination.
