Public Comment Period February 01, 2024-March 04, 2024

Ecology is proposing to remove the 7 Eleven 25821 site, located a 1824 George Washington Way in Richland, from its Hazardous Sites List (HSL).

The Hazardous Sites List is a list of sites Ecology reviewed for their potential threat to human health and the environment. This review is based on how much contamination is present, how toxic it is, and how easily it can come in contact with people and the environment. Sites must go through cleanup and meet state standards before Ecology can remove them from the list.

Review:

•  No Further Action Letter, dated January 7, 2021

Based upon cleanup activities conducted at the site, Ecology has determined the site is no longer a threat to human health and the environment.

Next Steps

After the public comment period ends, Ecology will review and respond to comments received and will hold a public meeting if 10 or more people request one. After review and consideration of comments received, the site will be removed from the Hazardous Site List.

Site Description

The site currently operates as a restaurant. The site formerly operated as a gas station and convenience store. 

In February 1989, three 10,000-gallon leaded- and unleaded-gasoline underground storage tanks (USTs) were removed from the property. Soil samples from showed gasoline and benzene, toluene, ethylbenzene, and xylene (BTEX) contamination remained under the former USTs above state cleanup levels. Groundwater samples showed gasoline and BTEX contamination as well. 

Cleanup Activities

Soil over-excavation and removal occurred during tank decommissioning. Contaminated soil
remaining on-site was treated with oxygen injections used to help with biodegradation. Soil sampling conducted between 2004 and 2015 demonstrated that cleanup was effective.

Groundwater monitoring was conducted between 1989 and 2020. Groundwater monitoring concluded when a minimum of four quarters of samples remained below MTCA cleanup levels.
