Model Toxics Control Act: Establishing Soil, Groundwater, and Surface Water Cleanup
From Policy & Regulations
This course provides attendees with an in-depth understanding of the procedures for establishing cleanup levels and points of compliance under the Model Toxics Control Act (WAC 173-340). The course covers procedures for establishing cleanup levels using Methods A, B, and C for groundwater, surface water and soil, as well as an overview of recent rule revisions related to dioxins/furans, PCBs, and carcinogenic PAHs. Additionally, the terrestrial ecological evaluation process to soils at sites will be covered. Participants will benefit from an overview of Washington State Department of Ecology's three and four-phase partitioning models, as well as their use of leaching test methods for determining soil concentrations that are protective of groundwater. Attendees will also have an opportunity to walk through the process of establishing cleanup standards using case studies. Both instructors have a deep and thorough understanding of MTCA and will welcome questions at the end of each topic.
