Periodic Review Draft Report Completed

Ecology invites you to review and comment on the Periodic Review Report for the Town Pump Gas Station Site. 

Comments will be accepted September 10, 2020 through October 12, 2020

You may submit your comments online or by mail to Frank Winslow, Site Manager, at Ecology's Central Regional Office. 

A periodic review is conducted at least every five years after the initiation of a cleanup action at a Site when required by the Model Toxics Control Act (MTCA).  The purposes of the review are to evaluate Site conditions after cleanup is considered complete, and to ensure protection of human health and the environment when institutional controls are used as part of a remedy.

We will review comments received during the comment period and make recommendations for suggested changes.  The periodic review will become final if no significant changes are made.  An additional public comment period will be held if significant changes are made.

The Town Pump Station Site is located at 521 East Jewett Boulevard, in White Salmon. The Site currently operates as a wholesale bakery.  It does not serve the public as a retail storefront.  The former trailer park to the south of the Site is being developed as residential housing.

Contaminated soils have been documented at the Site since 1989, when gasoline contaminated water was observed seeping into the trailer park located directly downgradient of the Site.

The Site is currently on Ecology’s Hazardous Sites List with a ranking of “1”.  Sites on the Hazardous Sites List are a priority for Ecology, and have completed a Site Hazard Assessment (SHA).  A SHA provides information about the environmental risk of the Site. Risk is based on the amount of contaminants, how toxic they are, and how easily they can come in contact with people and the environment.  Sites are ranked relative to each other on a scale of “1” to “5”; with a rank of “5” being the lowest.


The cleanup and removal of pumps, piping and tanks at the former Town Pump service station site and the associated bulk fuel storage was generally completed in two phases. 

Gas Station

The first of two work phases was to clean up the former Town Pump service station. This was largely completed in 1994.  Actions at the station included the removal of underground storage tanks and removal of accessible petroleum contaminated soils.

Bulk Fuel Storage

The second phase of work, completed late in 1996, addressed the bulk fuel storage area that supplied fuel to the Town Pump Station.  This consisted of the removal of four underground storage tanks and most of the associated piping from the hillside across Jewett Boulevard, above the Town Pump station.  Some of these tanks supplied fuel to the pumps at the former Town Pump through piping buried under the road. 

Soil samples collected from the vicinity of the tanks and lines were included in this phase of work, however no contaminated soil was found.  Petroleum contamination is known to exist beneath Jewett Boulevard, beginning at a depth of approximately 3 feet below the ground surface.  This contamination is thought to have been released from the two pipelines joining the tanks and the pumps.  That portion of the lines traveling underground just north of the station and beneath Jewett Boulevard does remain in place.

Finishing the Cleanup

To address petroleum contaminated soils remaining at the base of the retaining wall behind the service station site, a geomembrane barrier (similar to landscaping cloth) has been placed over the contamination to isolate it.  Further requirements include addressing the remaining petroleum contamination should the old service station building be demolished. 


Periodic reviews are conducted every 5 years by Ecology for sites that have Environmental Covenants and/or Institutional Controls. The review is intended to examine the effectiveness of cleanup activities and to assure the continued protection of human health and the environment.

Periodic Review Results

Based on the 2020 periodic review, the cleanup actions completed at the Site are protective of human health and the environment.

Soil cleanup levels have not been met at the Site; however, the cleanup action for the Property is determined to comply with cleanup standards under WAC 173-340-740(6)(f). Requirements for containment technologies have been met and the long-term integrity of the containment system (i.e. onsite structure) is provided for through institutional controls.

The Restrictive Covenant for the property is in place and is expected to be effective in protecting public health and the environment from exposure to hazardous substances and protecting the integrity of the cleanup action.

No additional remedial actions are required by the property owner.  It is the property owner’s responsibility to continue to inspect the Site to assure that the integrity of the cap (i.e. onsite structure) is maintained.
