Under the Toxic Substances Control Act, the U.S. Environmental Protection Agency evaluates the safety of existing chemicals through a three-stage process: prioritization, risk evaluation and risk management. Throughout this process, the agency uses various sources of exposure monitoring data to identify and evaluate high-priority substances or to set final risk management regulations.
This professional development course provides a brief overview of the occupational risk evaluation process under TSCA, followed by examples and lessons learned from EPA risk evaluations conducted to date. The course highlights key distinctions and challenges between historical industrial hygiene exposure evaluation methods and the EPA's TSCA process, using case examples for discussion.
Participants will perform risk calculations using EPA TSCA methods to understand how the agency determines whether a chemical presents an "unreasonable risk." The course emphasizes topics relevant to industrial hygienists and the occupational and environmental health and safety profession, including how exposure data may be collected and interpreted in EPA's risk evaluation and management approaches. It also addresses the importance and potential challenges the TSCA process presents to OEHS professionals.
*Note: This PDC will be conducted in Zoom. Please ensure the computer on which you will participate will allow Zoom to access all necessary computer systems including speakers, microphone, and camera.*

Learning Outcomes
Upon completion, the participant will be able to:
• Understand key aspects of TSCA occupational risk evaluations and terminology.
• Recognize differences between historical industrial exposure methods and the TSCA risk evaluation process through case study examples.
• Identify challenges in TSCA implementation and lessons learned.
• Understand key aspects of TSCA occupational risk evaluations and terminology.
• Recognize differences between historical industrial exposure methods and the TSCA risk evaluation process through case study examples.
• Identify challenges in TSCA implementation and lessons learned.
Prerequisites
Attendees should be familiar with the TSCA risk evaluation process and come prepared with specific questions or challenges. A brief introduction to the TSCA process will be provided as part of the course. Occupational and environmental health and safety professionals interested in understanding how TSCA may affect their organization or the broader OEHS field are encouraged to attend.
Value Added
This course equips industrial hygiene practitioners with the tools and concepts needed to recognize and address key steps and challenges in the TSCA risk evaluation process. It also enables occupational and environmental health and safety professionals to contribute meaningfully to broader discussions on this topic.
Business Case/IH Value Statement
Attendees will learn how EPA uses occupational monitoring data in risk evaluations and how exposure data may influence future assessments. The session will highlight TSCA's impact on health and safety professionals and explore opportunities for leadership in this evolving area.
