Carnation Dairies Spokane

Removing from the Hazardous Sites List

Sept. 8, 2020 - Oct. 7, 2020, 11:59 p.m.

Ecology proposes to remove the Carnation Dairies Spokane site from the Hazardous Sites List after contaminated soil was excavated.

The Hazardous Sites List includes all contaminated sites that have had their hazard ranked relative to other known contaminated sites in Washington. Sites are ranked on a scale of 1 to 5 with 1 presenting the highest risk. In 2013, Ecology ranked the Carnation Dairies Spokane site a 5 due to lead, cadmium, and diesel contamination in soil. However, only the diesel contamination was related to Carnation Dairies’ operations.

Soil and perched groundwater contamination occurred due to leaks from above- and underground storage tanks in use at the Carnation Dairies garage. In 1989, releases from the underground tanks were discovered and excavated. When the building was demolished in 1999, 74.5 tons of petroleum-contaminated soil related to the aboveground tank were disposed off-site. In 2019, soil was resampled as part of site redevelopment. Results showed contamination was below levels requiring further cleanup, so Ecology issued its no further action opinion.

Ecology will review comments received during the comment period. We will remove the site from the Hazardous Sites List if no significant changes are made due to public comment. We will hold an online public meeting if 10 people request it.
