Kens Auto Wash II

Proposed removal from the Hazardous Sites List

July 28, 2020 - Aug. 27, 2020, 11:59 p.m.

Kens Auto Wash II in Ellensburg has been cleaned up.

The site is located at 1013 East University Way in Ellensburg. It was built in 1988 and is currently operating as a convenience store and car wash. It was historically used as a gasoline station. In 1996, a leak was discovered during a tightness test for a fuel line connected to an underground storage tank (UST). An investigation revealed release of petroleum products to soil and groundwater. Approximately 520 tons of soil and 5,500 gallons of groundwater was removed and disposed of offsite. The USTs were also removed. Oxygen compounds as well as microbes and nutrients was injected into groundwater monitoring wells over the years to help the contamination break down. Groundwater has been sampled many times and data has continued to show that any remaining contamination is now below state cleanup standards.

We determined that the cleanup actions performed at the site show that any remaining contamiation is below state cleanup levels and the site no longer poses a threat to human health or the environment.

We're proposing to remove the site from the Hazardous Sites List, a statewide list of contaminated sites.

You are invited to review and comment on the:

We will review and respond to all comments received. A public meeting will be held if 10 or more people request one. After the comment period ends, the site will be removed from the Hazardous Sites List.

A site may be removed from the Hazardous Sites List only if the site is cleaned up to MTCA standards. In some cases, long-term monitoring and periodic reviews may be required to ensure the cleanup is adequate to protect the public and the environment. We hold a public comment period for any site we propose to remove from this list.
