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.
