Cleanup Complete

The Washtucna Fertilizer Plant site was removed from Ecology's Hazardous Sites List (HSL) in February 2015. The HSL contains all contaminated sites in Washington that have been evaluated and ranked. A rank of 1 indicates the greatest potential threat to human health and the environment and a rank of 5 the least potential threat. The site ranked a 5 based on petroleum and metal contamination in soil. 

Above-ground petroleum storage tanks were removed in 1975. Fuel has not been stored or sold at the site since 1975. A shed used for herbicide and pesticide storage and a shed used to store packaged petroleum products and agrichemicals have been removed.

In 2014, nearly 117 cubic yards of contaminated soil was removed and disposed off-site. Cleanup goals were met over an extended period of sampling that began in 1994. As a result of the cleanup work and sampling results, we issued a no further action letter stating cleanup is complete.
