NIMBioS Tutorial

Risk Assessment Calculator Training

Topic: U.S EPA and RAIS Screening Level Calculator Training for Chemical and Radionuclide Risk Analysis

Meeting dates: March 5-7, 2019

Location: NIMBioS at the University of Tennessee, Knoxville

Fred Dolislager, Leslie Galloway, Debra Stewart, and Karessa Manning
The Institute for Environmental Modeling, Univ. of Tenn. and Oak Ridge National Laboratory

Objectives: 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 all TIEM calculators. Additionally, the instruction will delve into the ability of the calculators to address site-specific exposures, unique toxicity assessments, and complex risk characterizations. With proper instruction, the calculators can provide all the tables necessary for exposure, toxicity, characterization, and uncertainty assessment sections of a risk assessment. 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 chemical-specific property sources and 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. Also presented will be TIEM's release of the RSL/RML mobile app (currently in development).

Day 3 of training (optional) covers radiation risk assessment. To attend the third day, participants must attend the first two days or receive prior permission from the training instructors. Day 3 will be fast-paced, and the calculator operational topics from the first two days will not be repeated.

This training is primarily intended for fresh and seasoned environmental professionals working on risk assessment projects at the Federal or State level. Our calculators are used by many State government agencies, Federal agencies, and university staff and researchers. Consultants, regulators, educators, and project managers will also benefit from the training. A very basic knowledge of risk assessment, computer usage, and web browsing is assumed.

Continuing Education Units (CEUs) available: Chemical risk tools = 1.3 credits; Radionuclide risk tools = 0.6 credits

Requirements: Bring your laptop! This is a hands-on course, and participants will be following the instructors click for click. Don't forget your charger. Instructors will be presenting all calculators using Chrome, so make sure Chrome is available on your laptop.  Not required, but useful would be spreadsheet software and a PDF viewer. Wi-Fi will be provided.

Topics: human health risk assessment, U.S. EPA guidance, cancer risk, hazard index, exposure assessment, toxicity assessment, risk characterization, 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), the risk assessment information system (RAIS), RSL/RML app.
