We invite you to review and comment on the draft periodic review report for the Zip Trip 25 cleanup site.
Ecology found a leak in a line to one of the fuel dispensers during an inspection in 2008. Further investigation showed petroleum contaminated soil as deep as 16 feet underground in limited areas around the underground storage tanks. After the extent of contamination was defined by completing soil borings, we issued a no further action opinion 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, we 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.
We visited the site Aug. 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.
We 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 one.
About periodic reviews
We conduct a periodic review at least every five years at cleanup sites where some contamination remains, as required by the Model Toxics Control Act (MTCA). The purposes of the review are to evaluate site conditions and to ensure continued protection of human health and the environment.
This is the second periodic review for this site.
