The EPA is issuing an advance notice of proposed rulemaking (ANPRM) under Section 6 of the Toxic Substances Control Act to gather information on the potential risks associated with N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and its transformation product, 6PPD-quinone, a substance often found in tire-rubber particles. In August 2023, the Yurok Tribe, the Port Gamble S’Klallam Tribe and the Puyallup Tribe of Indians submitted a petition under TSCA Section 21 asking EPA to establish regulations under TSCA Section 6 prohibiting the manufacturing, processing, use and distribution of 6PPD in tires. The EPA granted this petition in November 2023 and committed to publishing an ANPRM by Fall 2024 in order to gather more information that could be used to inform a subsequent regulatory action. The EPA will accept written comments on the ANPRM for 60 days following publication via the docket at Regulations.gov.
