MTCA Model Remedies

The Department of Ecology (Ecology) is undertaking a multi-year process to develop a series of guidance documents regarding model remedies. In 2013, the Washington Legislature made significant changes to the Model Toxics Control Act (MTCA). One of the new provisions provides additional direction to Ecology regarding the establishment of standardized cleanup methods called “Model Remedies.”

The MTCA statute defines model remedies to be “a set of technologies, procedures, and monitoring protocols identified by Ecology for use in routine types of clean-up projects at facilities that have common features and lower risk to human health and the environment.”

Several external meetings have been held to provide comments and feedback on the process for developing model remedies.


What is the purpose of developing model remedies?

Model remedies are intended to streamline and accelerate the selection of cleanup actions that protect human health and the environment, with a preference for permanent solutions to the maximum extent practical.


Model Remedies guidance now revised—send comments by September 22

We’ve updated our Model Remedies guidance for soils and groundwater, and you’re invited to comment on the changes.  Send your feedback to Mark Gordon by September 22, 2017:


Two listening sessions in September 2017

During the comment period for the model remedies guidance, Ecology will also hold two listening sessions in Lacey and Bellevue.  These sessions will be an opportunity for you to ask questions and give feedback on the model remedies guidance, as well as our new draft Implementation Memo No. 18: Petroleum Vapor Intrusion (VI): Updated Screening Levels, Cleanup Levels, and Sampling Considerations.  Ecology staff will be available for an open discussion on other topics of interest to the audience if time allows.  Please join us on:

  • September 11, 2017 from 1:00 to 3:00 p.m., room ROA-36 at Ecology Headquarters, Lacey, WA.
  • September 13, 2017 from 10:00 a.m. to 12:00 p.m., room 2A/B at Ecology’s Northwest Regional Office, Bellevue, WA.

What is the status of guidance development?

In January 2017, Ecology published a progress report titled, “Status of Developing Model Remedies: 2016 Report to the Governor and Legislature,” (publication no. 16-09-054).  The report was produced according to requirements outlined in RCW 70.105D.030(4) and describes:

  • How MTCA and model remedies facilitate contamination cleanups in Washington;
  • Which model remedies were used before 2013 and the new ones developed since then;
  • How Ecology engaged the public in the development process;
  • Opportunities to use model remedies in the future; and
  • Ecology’s next steps.

How can I stay informed about this guidance development effort?
