The Washington Department of Ecology (Ecology) invites you to comment on a Remedial Investigation (RI) report, Cleanup Action Plan (CAP) and the proposed removal from the Hazardous Sites List (HSL) for the former Chevron Bulk Terminal (site). Practices associated with the handling of petroleum and leaks from storage tanks and pipelines contaminated soil and groundwater.
The site was cleaned up by Chevron prior to entering into an Agreed Order with Ecology in 2003. To ensure that cleanup met state standards, the Agreed Order required Chevron to conduct an RI remedial investigation (RI) and feasibility study (FS) and implement the recommendations of the FS in a Cleanup Action Plan (CAP). Chevron wrote the draft RI report in 2015. Data in the report showed that TPH levels were below the Model Toxics Control Act (MTCA) Method B soil cleanup levels and no other TPH contamination remained at the site.
Chevron sampled groundwater between 1990 and 1995 and again between 2004 and 2015. Groundwater sampling stopped in 2015 after more
than eight quarters showed TPH contamination was below MTCA Method A groundwater cleanup levels.
Since the cleanup meets state standards, a Feasibility Study, which is typically written as part of the cleanup process is not required to evaluate
cleanup alternatives. Therefore, the preferred cleanup alternative of the site of the CAP is no further action.

The following documents are available for public comment:

that shows the nature and extent of contamination.
The draft 2018 CAP
that describes the recommended cleanup method and how it meets Ecology standards.
