PUBLIC COMMENT PERIOD MARCH 11, 2021-APRIL 11, 2021

Ecology invites your comment on the proposal to release the Exxon Station 73594 site from environmental covenant number 4971334 that is attached to the site.

A fact sheet briefly summarizes information about the site.
After cleanup, some lead contamination of groundwater remained at the site. To prevent exposure to that contamination, an environmental covenant was filed for the site in 2013. Results of groundwater monitoring in 2018 show that lead concentration in groundwater has decreased below state cleanup levels.

SITE DESCRIPTION
The Exxon Station 73594 is the site of a former Exxon service station located at 13204 Northeast Highway 99 in Vancouver.
When it was an auto service station, there was a gasoline pump station, service bays, and six underground petroleum storage tanks at the site. Currently, the site is occupied by a restaurant with an adjacent parking lot.
SITE CLEANUP
When the service station was operating, releases from underground storage tanks contaminated soil and groundwater with petroleum. Sometime prior to 1988, the underground storage tanks and the pump island were removed from the site.
Between 1988 and 2002 studies showed petroleum contamination of soil and petroleum and lead contamination of groundwater.
To clean up the site, a soil vapor extraction system was used to remove about 1,290 pounds of hydrocarbon vapors from soil and groundwater. In 2008, testing indicated that petroleum hydrocarbons in soil and groundwater had decreased to below state cleanup levels.
In 2010, groundwater monitoring confirmed the amount of lead in groundwater was above state cleanup levels. Based on the lead contamination in the groundwater, an environmental covenant was recorded for the site in 2013.
The covenant requires that no groundwater be taken for any use from the property and prohibits any activity on the property that may interfere with the integrity of the cleanup action. Ecology required a groundwater monitoring plan that included analysis for lead that would coincide with the timing of the 5-year periodic review.
Results of the compliance monitoring in October 2018 indicated that lead concentration in groundwater decreased and was below state cleanup levels.
In 2020, Ecology issued a No Further Action Letter and the owner requested removal of the environmental covenant from the property.
