Status Update

Ecology held a 30-day public comment period to delist this Site from the Hazardous Sites List from July 17 - August 17, 2020.  Ecology has reviewed and considered all comments received. 

Ecology issued a No Further Action Letter in August 21, 2020.  This Site was cleaned up under the Voluntary Cleanup Program (VCP).

Site Background

Current front view of building - Cleaning Center of Redmond facility
The source of contamination on the Property was the former dry cleaning machine that used the dry cleaning solvent PCE. A release of PCE to soil and groundwater was confirmed in 1999. PCE used was discontinued in 2002.

A
 strip mall currently occupies the Property, and went through a significant expansion in 2009.  The Cleaning Center of Redmond facility continues to operate in the tenant space at 15796 Redmond Way.   

Cleanup Conducted

Contaminated soil was over-excavated and removed from the Site.  A soil vapor extraction (SVE) remediation system was installed in 2003 and operated for 3 years to clean up PCE in soil and ground water.  Soil and ground water monitoring data was collected on a scheduled basis from 2003 through 2007, with confirmational sampling demonstrating that PCE no longer exceeded state cleanup levels.  Indoor air sampling was conducted in 2007 and 2010 in building spaces overlying the contaminant plume, to assess potential vapor impacts.  The results showed concentrations below state air cleanup levels.  As the Site was also defined by the release of PCE to ground water migrating off-Property toward the Sammamish River, a computer model demonstration was conducted in 2018.  The model confirmed that PCE remaining in soil or ground water (below cleanup standards) will not result in future exceedances of the ground water cleanup levels for the Site, including ground water that discharges into the Sammamish River.
 

Contaminants Of Concern

  • Tetrachloroethene (PCE) into the Soil
  • PCE into the Groundwater
  • PCE into the Soil Gas

Voluntary Cleanup Program

This Site is under the Voluntary Cleanup Program  (VCP) at the Washington State Department of Ecology (Ecology) Northwest Regional Office. The VCP enables owners of contaminated Sites to meet state cleanup standards independently and to receive technical guidance and opinions from Ecology during the cleanup process.  

The VCP allows owners an opportunity to clean up their contaminated Sites on a contractual basis rather than under an Ecology legal order. Participants in the VCP pay fees to Ecology to cover the department’s costs for guidance and review. VCP Sites must meet the same cleanup standards as formal (under legal agreements) Sites managed by Ecology.  Formal and VCP Sites are regulated by the state’s cleanup law, the Model Toxics Control Act, which was created by a 1989 voter initiative.
