Description/Purpose
The Model Toxics Control Act (MTCA) is a citizen-mandated hazardous waste cleanup law. Under the MTCA regulations, owners and operators must report to Ecology any release or threatened release of a hazardous substance on their site. A verbal or written report must be made within ninety days of discovery unless the release is from a regulated underground storage tank (typically gas stations), which must be reported within 24 hours. These notification requirements apply to both current and historical releases. Please note that releases to surface water or from permitted hazardous waste storage, treatment, or disposal facilities have more stringent reporting requirements. Refer to the "Reporting Requirement for a Spill or Release of a Hazardous Chemical" for reporting information on these types of releases.
Ecology conducts an initial investigation of all reported sites and, if appropriate, the site will be placed on Ecology's "confirmed and suspected sites list" with a notation that further remedial action is needed.
The MTCA regulations also allow for site owners or other responsible persons to clean up a site themselves, without Ecology's oversight or approval. These "independent" cleanups must be reported to Ecology. Owners of sites undergoing independent remedial actions may receive feedback from Ecology by requesting an informal opinion through Ecology's Voluntary Cleanup Program (VCP). Under this voluntary program, the property owner submits a cleanup report with a fee to cover Ecology's review costs. Based on this review, Ecology either issues a "No Further Action" letter or identifies what additional work is needed. Refer to the "Voluntary Cleanup Program" for further information on Ecology's review procedures.
Persons wanting a more formal approval of the cleanup from Ecology can request an agreed order or consent decree. Ecology can also initiate negotiations on an agreed order or consent decree. Where insufficient progress on cleanup has been made, Ecology may issue an enforcement order. Under these options, Ecology oversees in detail activities such as site investigations, public involvement, cleanup, and monitoring.
Triggers and activities which would require this compliance record
In general, all activities that release hazardous substances to the environment must comply with the MTCA reporting requirement. However, the MTCA Cleanup Regulation (Chapter 173-340 WAC) includes several exemptions from the notification requirement (See WAC 173-340-300(2).
If a person decides to investigate or clean up a site, they must comply with the site testing and cleanup actions requirements in the MTCA Cleanup Regulation.
No permit is required under MTCA to investigate or cleanup a site. However, people may need to obtain other state or local permits for these activities.
Notes / Comments
There are no application forms for reporting releases of hazardous substances. Refer to the "Voluntary Cleanup Program" for information on the application process for reviews conducted under that program.
Releases should be reported by phone or written report to the appropriate Ecology regional office. Guidance for reporting releases can be found in the Toxics Cleanup Program's Policy 300.
Costs for oversight of cleanups under an order or decree are governed by the specific legal agreement (generally billed monthly).
