## II. Background

### A. What is the purpose of the SACC?

                    The SACC was established by EPA in 2016 and operates in accordance with the Federal Advisory Committee Act (FACA), 5 U.S.C. Appendix 2                     *et seq.*                     The SACC provides expert independent scientific advice and consultation to the EPA on the scientific and technical aspects of risk assessments, methodologies, and pollution prevention measures and approaches for chemicals regulated under TSCA.                

                    The SACC is comprised of experts in: Toxicology; Human health and environmental risk assessment; Exposure assessment; and related sciences (                    *e.g.,*                     biology, chemistry, pharmacology, biotechnology, nanotechnology, biochemistry, biostatistics, physiologically based pharmacokinetic modelling (PBPK) modeling, computational toxicology, epidemiology, environmental fate, and environmental engineering and sustainability). When needed, the committee members will be assisted in their reviews by consultants with specific expertise in the topics under consideration.                

### B. What is the purpose of this virtual public meeting?

The purpose of this virtual public meeting of the SACC is to consider and review the draft document entitled “EPA TSCA Screening Level Approach for Assessing Ambient Air and Water Exposures to Fenceline Communities Version 1.0,” which will be presented as a screening level methodology for assessing potential air and water chemical exposures to fenceline communities.

                    EPA published ten final risk evaluations between 2020 and 2021 under the Toxic Substances Control Act (TSCA) as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in June 2016. During the course of finalizing many of these first 10 risk evaluations, a policy decision was made by the previous Administration that EPA not assess air and water exposure pathways that fall under the jurisdiction of other EPA-administered laws. This policy decision was reversed in June 2021. EPA is presenting 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 will also present results of applying the screening methodology (case studies) to 1-Brompropane or 1-BP (air pathway), n-methylpyrrolidone or NMP (water                           ( print page 3296)                        pathway), and Methylene Chloride or MC (air and water pathway).                

### C. How can I access the documents submitted for review to the SACC?

                    EPA's background documents, related supporting materials, and draft charge questions to the SACC are available in the docket established for this meeting at                     *https://www.regulations.gov;*                     docket ID number EPA-HQ-OPPT-2021-0415 and on the SACC website. In addition, EPA will provide additional background documents (                    *e.g.,*                     SACC members and consultants participating in this meeting and the meeting agenda) as the materials become available. You may obtain electronic copies of these documents, and certain other related documents that might be available, in the docket at                     *https://www.regulations.gov*                     and the SACC website at                     *https://www.epa.gov/​tsca-peer-review.*

After the public meeting, the SACC will prepare meeting minutes summarizing its recommendations to the EPA. The meeting minutes will be posted on the SACC website and in the docket.
