Model Toxics Control Act

Model Toxics Control Act
Model Toxics Control Act

The Model Toxics Control Act (MTCA) is Washington’s environmental cleanup law.  It provides requirements for contaminated site cleanup and sets standards that protect human health and the environment.  Ecology enacts the MTCA and oversees cleanups.
​The MTCA site cleanup process is completed in steps over a variable timeline. 

Site History

Tiki Car Wash has been in operation since 1971 as a gasoline station and car wash. The site is located at 11909 N.E. 8th Street, Bellevue, WA.

In 1990, Ecology received a report that a release of petroleum compounds may have taken place on the car wash property.

Tiki Enterprises and the Washington State Department of Ecology entered into a Consent Decree (CD) (No. 93-2-07710-6) on March 29, 1993. The CD was to draft the Remedial Investigation and Feasibility (RI/FS) Study, draft a Cleanup Action Plan (DCAP), and to implement the Cleanup Action Plan (CAP).  

The Remedial Investigation and Feasibility Study were drafted in September 2010, however these documents have not been finalized and have not gone out for Public Comment, due to the significant data gaps identified in the draft Remedial Investigation.

Remedial Investigation drafted in September 2010, needs to be updated and previously identified data gaps need to be addressed. The Feasibility Study may need to be revised depending on results of a final remedial investigation.
