Ecology invites your comments on the draft periodic review report for the McDonald's Restaurant site. 

Environmental cleanup is complete at the site, and the draft periodic review report shows that 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 soil contamination remained at the site. To prevent exposure to that contamination, a restrictive covenant was filed for the site in 1999. The covenant restricts property use and requires maintenance of a pavement cap to eliminate exposure to contaminated soil.

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.


For several decades before the late 1980s, the site was the location of a bulk heating oil storage facility with four above ground storage tanks. The tanks were removed sometime between 1984 and 1989. During construction of the McDonald's Restaurant in 1989, petroleum hydrocarbon contamination was discovered in soil and groundwater.

The owner conducted the following cleanup activities at the site:

  • Removed and disposed of more than 3,000 cubic yards of petroleum contaminated soil. 
  • Pumped and treated 1.9 million gallons of water to remove petroleum contamination from groundwater.

After cleanup, soil samples collected at the site indicated that all but two areas were below petroleum cleanup levels.  Excavation of more soil from the two remaining contaminated areas was limited by the location of power poles, utilities, and the sidewalk. The contaminated areas were capped with asphalt/concrete. The owner installed groundwater wells and monitors water quality to assure the contaminated soil does not contaminate groundwater.

Based on Ecology's inspection on February 13, 2018, the pavement cap around the restaurant and parking lot is in satisfactory condition and continues to eliminate exposure to contamination.
