Update #19 on Olympic Pipeline Gasoline Spill

The Unified Command leading the response to the discharge of gasoline from a vault associated with the Olympic Pipeline in Conway, Washington has the following updates on the progress of cleanup efforts.

Cofferdam installation


The sheet pile cofferdam is installed, and fish exclusion nets are removed. Preparations for excavation are in progress with excavation likely beginning next week. A dewatering system will be installed to remove water from the soil inside the cofferdam. Water removed from the soil will be cleaned and returned to the environment. Contaminated soil will be excavated for disposal.

Surface water sampling during excavation will continue.

Photos and video of this week’s progress are available on Ecology’s Flickr and YouTube sites.

Air monitoring and potential gas odor

During excavation, mild gasoline odor may be noticeable near the site. When excavation begins, enhanced air monitoring on the site will ensure the safety of response workers. Community air monitoring will continue to ensure protection of the public. Based on sampling data, we do not expect air sampling levels to exceed safety thresholds.

General information

The Unified Command asks members of the community and public to continue reporting sheens in Hill Ditch by emailing Liaison@ecy.wa.gov. To report sheens outside Hill Ditch, call 1-800-OILS-911.

Air monitoring conducted at the direction of the Unified Command continues to indicate no public health risk from gasoline fumes. Community air monitoring will continue during work hours when impacted soil is being removed.

Sampling downstream of the spill site continues and no exceedances of environmental or health-based screening values for hydrocarbons have been reported at any location since December 22, 2023.

Members of the public who come upon injured or deceased wildlife are asked not to touch or relocate affected wildlife and to call 1-800-22BIRDS.

A claims center has been established by the Olympic Pipeline. Please call 1-866-616-1558 to report any personal or property damages resulting from the spill.

The Unified Command consists of the U.S. Environmental Protection Agency, the Washington Department of Ecology, the Skagit County Department of Emergency Management, bp, and the Swinomish Indian Tribal Community.
