PUBLIC COMMENT PERIOD OCTOBER 04, 2021-NOVEMBER 02, 2021

Ecology invites you to review and comment on the draft periodic review report for the Zip Trip 25 site. We conduct a periodic review at least every five years after beginning cleanup at a site, and this is the second periodic review for this site. The purpose of the review is to evaluate current site conditions and to ensure the continued protection of people and the environment.

Ecology visited the site August 24, 2021, for the periodic review and found that the protective asphalt cap over contaminated soil remains intact. The site is still a gas station and convenience store, now operating under the name Nom Nom.

Submit comments by 11/2 to:

Next steps

Ecology will publish our responses to all comments received during the comment period. The periodic review will become final if no significant changes are made to the draft report as result of comments. An additional public comment period will be held if significant changes are made. We will hold an online public meeting if 10 or more people request it.

CLEANUP COMPLETE

The Zip Trip 25 (now doing business as Nom Nom) is a gas station and convenience store that's been in business since 1979. Three 10,000-gallon underground storage tanks (USTs) (one regular gasoline, one mid-grade gasoline, and one premium gasoline) are used to dispense fuel.

Ecology found a leak in a line to one of the fuel dispensers during an inspection in February 2008. That April, soil samples were taken by cutting the asphalt and using a hand auger. The investigation showed petroleum-contaminated soil as deep as 16 feet underground in limited areas around the underground storage tanks. However, from 16-20 feet, petroleum was not found. In August, at Ecology's request, more soil samples were collected from 12-14 feet and 14-16 feet underground. Those samples did not contain petroleum at levels requiring cleanup.

After the extent of contamination was defined by completing soil sampling, we issued a no further action letter stating cleanup was complete because the contaminated soil was capped with asphalt and groundwater wasn’t affected. Excavating the contaminated soil would have required the tanks to be removed. However, because of the remaining contamination, Ecology filed an environmental covenant for the property to prevent activities that would expose humans and the environment to remaining contamination and warn future owners of its presence.


POST-CLEANUP REVIEWS

We conduct a periodic review at least every five years after initial cleanup is complete at a site. The purpose of the review is to evaluate current site conditions and to ensure the continued protection of people and the environment.

Following our no further action opinion in 2009, we have completed two periodic reviews for the Zip Trip 25 site. After both site visits, we concluded that the protective asphalt cap over contaminated soil remains intact. You can learn more in the periodic review reports:
