Organizers:

  • Fred Dolislager, The Institute for Environmental Modeling, Univ. of Tenn. and Oak Ridge National Laboratory
  • Leslie Galloway, The Institute for Environmental Modeling, Univ. of Tenn. and Oak Ridge National Laboratory
  • Debra Stewart, The Institute for Environmental Modeling, Univ. of Tenn. and Oak Ridge National Laboratory
  • 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 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 calculators ability to 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 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. Also presented will be TIEM's release of the RSL/RML app (currently in development).

  • Day 1: Registration at ORNL and half day of tours at ORNL including visiting the Spallation Neutron Source facility and the High Flux Isotope Reactor.
  • Day 2: First day of training on chemical tools and a tour of either the supercomputer (Summit) or the Historic Graphite Reactor.
  • Day 3: Second day of training on chemical tools and a tour of either the supercomputer (Summit) or the Historic Graphite Reactor.
  • Day 4: Optional day that covers radiation risk assessment. To attend the fourth day, participants must attend the chemical training or receive prior permission from the training instructors. Day 4 will be fast-paced, and the calculator operational topics from the chemical training 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. The risk calculators covered in this training are used by many State government agencies, Federal agencies, and university staff and researchers. Participants, educators, and project managers will also benefit from the training. A very basic knowledge of risk assessment, computer usage, web browsing, and good manners is assumed.

Continuing Education Credits:
Chemical risk tools = 1.7 credits (Days 1-3); Radionuclide risk tools = 0.7 credits (Day 4)

Previous Course Evaluations:
March 2019

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.
