Author(s) Toxics Cleanup Program
Description The Model Toxics Control Act (MTCA), Chapter 70.105D RCW, requires the Department of Ecology (Ecology) to establish a program to identify sites potentially contaminated with hazardous substances. That program is set forth in WAC 173-340-300, which is part of the MTCA Cleanup Regulation, chapter 173-340 WAC. Under that program, Ecology requires owners and operators to report releases of hazardous substances occurring as consequence of past practices. Releases occurring as a consequence of current practices must be reported under other authorities.

This policy provides guidance on the types of releases that should be reported under WAC 173-340-300 and the procedures for reporting such releases.

Revision note: The content of this policy was last revised June 10, 2004. In June 2018, this document was formatted and cataloged in Ecology’s publications database, but no content was changed since the June 2004 revision.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
