EPA’s Draft TSCA Screening Methodology to Evaluate Chemical Exposures and Risks to Fenceline Communities

On January 21, 2022, EPA published its draft “TSCA Screening Methodology to Evaluate Chemical Exposures and Risks to Fenceline Communities.” EPA plans to use the screening level methodology to evaluate potential chemical exposures and associated potential risks to fenceline communities in its Toxic Substances Control Act (TSCA) risk evaluations. EPA defines fenceline communities as members of the general population that are in proximity to air emitting facilities or a receiving waterbody. In the methodology, EPA limits the chemical release to the ambient air to less than or equal to 10,000 meters but does not provide a limit for waterbodies other that it must be the receiving waterbody of the chemical discharge. The agency intends to apply the screening level methodology to seven of the “first 10” chemicals undergoing risk evaluation under TSCA Section 6, which include methylene chloride (MC), 1-bromopropane (1-BP), n-methyl-2-pyrrolidone (NMP), trichloroethylene, perchloroethylene, carbon tetrachloride and 1-4 dioxane. This methodology will also be employed by the agency for all future chemicals undergoing the risk evaluation process under TSCA. The agency recently extended its public comment deadline from February 22, 2022 to March 22, 2022.

EPA is also planning to hold a virtual peer review meeting of the Science Advisory Committee on Chemicals (SACC) March 15-17, 2022, to consider and review this methodology along with its application to 1-BP, NMP and MC.

Speaker Bio: American Composites Manufacturers

The American Composites Manufacturers Association (ACMA) represents an industry comprised of more than 1,000 facilities producing fiber reinforced polymer composite products, the majority of which are owned by small companies. Composites manufacturers have long been regulated under VOC, HAP, and state air toxics programs, and many have been required to conduct exposure modeling using EPA-approved methods.  John Schweitzer is a Senior Advisor at ACMA. Rob Haberlin is the owner of Engineering Environmental Consulting Services (EECS) and has provided occupational, environmental, and litigation support to composite manufacturers, and other large and small manufacturers since 1991.
