Description
Under the amended Toxic Substances Control Act (TSCA), the U. S. EPA must evaluate chemical risks across diverse Conditions of Use (COUs) and Occupational Exposure Scenarios (OESs). With over 15 risk evaluations completed, a strategic opportunity has emerged to systematize OES development and improve exposure estimation.
This roundtable will bring together EPA officials, industry experts, and consultants to share insights and propose collaborative solutions for enhancing the transparency, efficiency, and scientific rigor of occupational exposure assessments. EPA representatives will outline recent efforts to define procedures and sources for identifying COUs and OESs. Industry and consulting experts will present practical approaches to use mapping and scenario construction, including the concept of sentinel scenarios high-exposure benchmarks that support consistent evaluations and early screening.
The session will explore a tiered assessment framework using default scenarios and conservative parameters, refined with empirical data when needed. A panel discussion will highlight opportunities for harmonizing data formats and identifying key exposure determinants to enable cross-sector data grouping.
This session will demonstrate how collaboration can lead to more predictable risk evaluations, realistic exposure assumptions, and targeted risk management strategies.

Learning Outcomes
Upon completion, the participant will be able to:
• Assess EPA's current procedures for identifying COUs and OESs under TSCA, and explain how these are applied in chemical risk evaluations relevant to occupational health.
• Apply the concept of sentinel scenarios to support consistent exposure benchmarking and early screening of low-priority occupational scenarios.
• Construct sector-specific use maps and generic exposure scenarios using technical literature, industry reports, and engineering references to support more realistic and representative assessments.
• Implement a tiered exposure assessment approach that begins with default scenarios and conservative parameters, and refines them using specific industry data or empirical measurements.
• Identify key exposure determinants and opportunities to harmonize data formats across sectors to enable grouping of occupational exposure data and improve transparency in risk evaluations.
