Tennessee Department of Environment and Conservation (TDEC) Offices, Oak Ridge, Tennessee. This training is intended for TDEC and UCOR staff to be updated on the latest changes to the EPA calculators.
April 25-26, 2022.
Human health risk assessment, U.S. EPA guidance, cancer risk, hazard assessment, exposure assessment, toxicity assessment, risk characterization, EPA regional screening levels (RSLs), regional removal management levels (RMLs), vapor intrusion screening levels (VISL), radionuclide preliminary remediation goals for radionuclides (PRGSs), radionuclide dose compliance calculators (DCCs), radon vapor intrusion screening levels (RVISL), and the risk assessment information system (RAIS).
Not open to the public.
The Institute for Environmental Modeling (TIEM) team has been publishing online "risk" (cancer risk and hazard index) calculators for over twenty years; this training will foremost provide the participant with operational knowledge of key TIEM calculators. Additionally, the training and exercises will delve into the ability of the calculators to address site-specific exposures, unique toxicity assessments, and complex risk characterizations. Comprehensive instruction will demonstrate the ability to provide all the components necessary for exposure, toxicity, characterization, and uncertainty assessment sections of a risk assessment using the calculators. Instruction into the details of the equations will enlighten users on how the calculators handle the following special cases: mutagens, vinyl chloride, trichloroethylene, arsenic, dioxin-like PCBs, PAHs, skin absorption factors, volatile chemicals in soil, volatile chemicals in tap water, petroleum hydrocarbons, surrogate toxicity values, soil saturation, and soil screening levels protective of contaminant migration to groundwater. Participants will learn to adjust standard chronic land uses to subchronic exposures. Participants will learn to retrieve and analyze the physicochemical properties and evaluate the hierarchy used to assemble the database. Participants will learn to retrieve and analyze the toxicity value hierarchy used in the screening level and risk calculators. In addition to a large focus on developing risk-based screening levels, participants will derive "forward" risk results from the EPA screening calculators and use the RAIS calculators to generate chronic daily intakes and risk results. At the end of each day, several practice sessions will reinforce the use of calculator functions. Practice sessions will become more challenging as the course progresses, helping participants solidify their risk assessment skills.
