Summary: This three-day training series provides a comprehensive overview and refresher of Washington State's Model Toxics Control Act (MTCA). MTCA directs the investigation and cleanup of contaminated sites in Washington. MTCA applies to contaminated soil, groundwater, air, and surface water in freshwater and marine environments.

Intended Audience: This training is intended for environmental consultants, agency staff, and others seeking an improved understanding of MTCA and its application to contaminated sites in Washington State. The one-day MTCA introduction is intended for anyone needing a general understanding of MTCA including technical staff, supervisors, and potentially liable persons (PLPs). The two-day technical training is recommended for those implementing MTCA at cleanup sites.
Prerequisites: There are no prerequisites for the introductory course on Nov. 8. The introductory course, similar MTCA training, or working knowledge of MTCA is recommended for everyone attending the technical training on Nov. 9 - 10.
Education Level: Introductory to advanced (and a good refresher for those already familiar with the rule). General principles and more advanced topics are presented to ensure all levels benefit from attending.
Course Materials: 2022 updated course proceedings including presentation slides and resources.
Credit: 22.5 PDHs or 2.25 CEUs for completing 22.5 hours of instruction in three days.
Registration for MTCA Series (Nov. 8 - 10, 2022): $495, $395 per person for small groups of 2 - 9 people, and $350 per person for large groups of 10 or more on the same registration. Register online or by calling us at (800) 385-0783. If you prefer to take only one of the two classes, you may register for the Introduction to MTCA course here and the MTCA Implementation course here. Each participant can attend the courses on their own computer.
Location: Your office or home - anywhere you can get comfortable and online.
