C.I. Pigment Violet 29 (PV29); Regulation Under the Toxic Substances Control Act (TSCA)

The Environmental Protection Agency (EPA or Agency) is proposing to address the unreasonable risk of injury to human health presented by C.I. Pigment Violet 29 (CASRN 81-33-4, also known as PV29), under its conditions of use as documented in EPA's January 2021 Risk Evaluation for PV29 and the September 2022 Revised Risk Determination for PV29 prepared under TSCA. 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 is proposing requirements to protect workers from the unreasonable risk of PV29 during manufacturing and processing, certain industrial and commercial uses of the chemical, and disposal, while also allowing for a reasonable transition period prior to enforcement of said requirements.
