Ecology invites your comments on the draft Periodic Review Report for the Exxon Station 73594 site.

Environmental cleanup is complete at the site and the draft Periodic Review report shows that the cleanup work remains effective in protecting the health of people and the environment. Ecology may modify the draft report if new information is submitted during the comment period.

After cleanup, some lead contamination of groundwater remained at the site. To prevent exposure to that contamination, a restrictive covenant was filed for the site in 2013. The covenant restricts property use and requires maintenance of the property to eliminate possible contact with groundwater. Results of groundwater monitoring in 2018 indicate that lead levels in groundwater have decreased below state cleanup levels.

When an environmental covenant exists for a cleanup site, Ecology reviews site conditions at least every five years to ensure long-term effectiveness of the cleanup action.

Based on Ecology's inspection of the site on January 11, 2019, conditions of the parking lot and the Taco Bell restaurant building are in satisfactory condition to eliminate exposure to groundwater and recent groundwater analysis indicates lead concentration in groundwater have decreased below state cleanup levels. 


Draft Periodic Review Report


The Exxon Station 73594 is the site of a former Exxon service station located at 13204 Northeast Highway 99 in Vancouver, Wa. When it was an auto service station, the site included a gasoline pump station, service bays, and six underground petroleum storage tanks.  Currently, the site is occupied by a Taco Bell restaurant with an adjacent parking lot. 


During operation of the Exxon service station, there were known releases from underground storage tanks that 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 a number of 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 approximately 1,290 pounds of hydrocarbon vapors from soil and groundwater. In 2008, testing indicated that petroleum hydrocarbons in soil and groundwater had decreased below state cleanup levels.  

In 2010, groundwater sampling confirmed that lead concentration was above state cleanup levels. Based on the lead contamination remaining in the groundwater, a restrictive 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.  A no further action letter from 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 concentrations in groundwater decreased and were below state cleanup levels.
