Facility Site ID: 390 Cleanup Site ID: 4762

The site is the location of area-wide subsurface petroleum contamination in the city of Cle Elum. In 1991, during trench excavations for a telephone line installation across the street from a Texaco service station (Simpsons Texaco) a U.S. West crew encountered approximately one inch of free petroleum product.  As there were several suspected contaminant sources under investigation at that time, for administrative purposes the site was listed, assessed, scored and ranked under the name Cle Elum Petroleum Contamination, and later changed to Cle Elum City with notes: Highway 903, site of interest extends approximately two miles.

This area was initially assessed and ranked by the Kittitas County Health Department in mid-1996. The contaminants of concern at that time were total petroleum hydrocarbons expressed both as gasoline and diesel.

In May 2021, an investigation was conducted for Ecology by GeoEngineers. The investigation indicates that no contamination is present at the Site at concentrations above cleanup levels that would suggest the need for further investigation or cleanup.

In August 2021, Ecology issued a no further action letter. In April 2024, the site was updated to reflect a no further action status after a public comment period to remove the site from Ecology's Hazardous Sites List.
