News to upload Title: EPA Carbon Tetrachloride Risk Evaluation On August 29, 2022 (87 FR 52766), the Environmental Protection Agency (EPA) published a notice in the federal register announcing the availability of and requesting public comment on a draft revision to the risk determination for the carbon tetrachloride risk evaluation issued under the Toxic Substances Control Act (TSCA). The draft revision to the carbon tetrachloride risk determination reflects the announced policy changes to ensure the public is protected from unreasonable risks from chemicals in a way that is supported by science and the law. In this draft revision to the risk determination EPA finds that carbon tetrachloride, as a whole chemical substance, presents an unreasonable risk of injury to health when evaluated under its conditions of use. In addition, this draft revised risk determination does not reflect an assumption that all workers always appropriately wear personal protective equipment (PPE). EPA understands that there could be occupational safety protections in place at workplace locations; however, not assuming use of PPE reflects EPA’s recognition that unreasonable risk may exist for subpopulations of workers that may be highly exposed because they are not covered by the standards set by the Occupational Safety and Health Administration (OSHA), or their employers are out of compliance with OSHA standards, or because many of OSHA’s chemical-specific permissible exposure limits largely adopted in the 1970’s are described by OSHA as being “outdated and inadequate for ensuring protection of worker health.” This revision, when final, would supersede the condition of use-specific no unreasonable risk determinations in the 2020 Carbon Tetrachloride Risk Evaluation (and withdraw the associated order) and would make a revised determination of unreasonable risk for carbon tetrachloride as a whole chemical substance. Comments must be received on or before September 28, 2022.
