(BELLINGHAM)– Trans Mountain Pipeline (Puget Sound) LLC plans to clean up petroleum-contaminated soil at its Laurel Station facility, a pump station about 4 miles north of Bellingham.
The cleanup will be conducted under a proposed legal agreement with the Washington Department of Ecology. Ecology seeks public comment on the agreement and related documents through May 19, 2014.
Petroleum leaks and spills occurred on the 15-acre site at 1009 E. Smith Road between 1971 and 2000. Trans Mountain has conducted several cleanup projects since 1991 that have removed most of the contamination. The current project will clean up contaminated soil that remains in three parts of the pump station.
Trans Mountain will excavate accessible soil for disposal off-site. Highly contaminated soil under buildings or other facilities will undergo subsurface cleanup. Lightly contaminated soil under pavement, buildings or facilities will remain in place until exposed by maintenance.
Post-cleanup monitoring will assess the cleanup’s effectiveness, and Trans Mountain will perform additional cleanup if needed.
