Unocal Edmonds Bulk Fuel Terminal 0178 cleanup site

The Unocal Edmonds Bulk Fuel Terminal 0178 cleanup site is located near the Edmonds waterfront and consists of an Upper and Lower Yard. Unocal is a subsidiary of Chevron Corporation, and Chevron Environmental Management Company (CEMC) is conducting the cleanup under Ecology’s oversight.

Multiple Interim Actions (or early partial cleanups) have been completed to remove petroleum floating on groundwater and soil contaminated with arsenic and petroleum. The Upper Yard portion of the site was cleaned up in 2003 and the cleanup of the Lower Yard portion is near completion. Remaining contamination is potentially harmful and must be addressed under Washington’s cleanup law.

The following documents are available for review:

• Revised Draft Feasibility Study: An evaluation of ways to clean up the site, and a recommended preferred cleanup option. This includes:
  • 2017 Draft Feasibility Study
  • 2024 Draft Feasibility Study Addendum
  • Site-specific Terrestrial Ecological Evaluation
• Updated Public Participation Plan: A document explaining how people can participate in the cleanup process.
