On January 14, 2025, the U.S. Environmental Protection Agency (EPA) issued a proposed rule to address the unreasonable risk of injury to human health presented by Color Index (C.I.) Pigment Violet 29 (PV29) under its conditions of use (COU) as documented in EPA’s January 2021 risk evaluation and September 2022 revised risk determination. 90 Fed. Reg. 3107. The proposed rule states that the Toxic Substances Control Act (TSCA) requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. To address the identified unreasonable risk, EPA proposes requirements to protect workers during manufacturing and processing, certain industrial and commercial uses of PV29, and disposal, while also allowing for a reasonable transition period prior to enforcement of said requirements. Comments are due February 28, 2025. EPA notes that under the Paperwork Reduction Act (PRA), comments on the information collection provisions are best assured of consideration if the Office of Management and Budget (OMB) receives comments on or before February 13, 2025. For more information, please read our full memorandum.
