TSCA Screening Level Approach for Assessing Ambient Air and Water Exposures to Fenceline Communities
In January 2022, EPA released for public comment and peer review Version 1.0 of a proposed screening level methodology to evaluate potential chemical exposures and associated potential risks to fenceline communities in Toxic Substances Control Act (TSCA) risk evaluations.
The proposed screening level methodology uses reasonably available data, information, and models to quantify environmental releases, evaluate exposures to fenceline communities and characterize risks associated with such releases and exposures.
EPA held a public virtual meeting of the SACC on March 15-17, 2022, to peer review the screening level methodology. Information on the public virtual meeting is available on the SACC website.
