Corporate Training By Zack Academy - Model Toxics Control Act: Establishing Soil, Groundwater, and Surface Water Cleanup

Why Should You Take This Model Toxics Control Act: Establishing Soil, Groundwater, and Surface Water Cleanup course?

Gain an in-depth understanding of the procedures for establishing cleanup levels and points of compliance under the Model Toxics Control Act (WAC 173-340) in this 2-day Model Toxics Control Act: Establishing Soil, Groundwater, and Surface Water Cleanup course. 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.

Prerequisites:

Attendees are encouraged to take "Introduction to the Model Toxixs Control Act" to prepare for this course.

Intended Audience:

This course is intended for environmental professionals seeking an improved understanding of the establishment of cleanup levels under MTCA.

Topics To Be Covered Include:

• Hands-On Case Studies and Questions (integrated throughout workshop)
• Process for Reaching No Further Action
• Conceptual Site Model Development for MTCA
• Land Use and Beneficial Uses of Groundwater and Surface Water
• Applicability of Methods A, B, and C
• Identifying Indicator Hazardous Substances (screening levels, frequency of detection, natural background concentrations)
• Surface Water CULs (ARARs, Equations) and Points of Compliance (POCs)
• Groundwater CULs (ARARs, Equations, Protection of Surface Water) and POCs
• Direct Contact Soil CULs
• Modeling the Leaching Pathway (3- and 4-phase models)
• Vapor Pathway and Dermal Contact (applicability, how to evaluate)
• Determining Residual Saturation Concentrations
• Terrestrial Ecological Evaluations (TEE) - Simplified, Site-Specific, and Exclusions
• Determine POCs for Soil
• Evaluating Compliance with CULs (direct comparison, 3 part statistical rule)
• Determining Whether Institutional Controls are Required
• Overview of Proposed Amendments: clarifying cleanup levels for mixtures of dioxins/furans; carcinogenic PAHs, and PCBs

What to Bring to Class:  Pen or pencil, and paper if you do not want to take notes in your manual. Drinks and snacks will be provided each day. Lunch will be on your own.
