Peer Review of the EPA TSCA Screening Level Approach for Assessing Ambient Air and Water Exposures to Fenceline Communities

On March 15-17, 2022, EPA held a public virtual meeting of the Science Advisory Committee on Chemicals (SACC) to peer review EPA Toxic Substances Control Act (TSCA) Screening Level Approach for Assessing Ambient Air and Water Exposures to Fenceline Communities. EPA presented Version 1.0 of a screening level methodology for assessing potential air and water pathway chemical exposures to fenceline communities. Along with presenting this methodology, EPA also presented results of applying the screening methodology (case studies) to 1-Brompropane (air pathway), n-methylpyrrolidone (water pathway), and Methylene Chloride (air and water pathway). The agency will use the scientific advice, information, and recommendations from the SACC, as well as public comments, to inform the final protocol.
