1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-Hexamethylcyclopenta [g]-2-Benzopyran (HHCB) and Phthalic Anhydride Draft Risk Evaluations Under the Toxic Substances Control Act (TSCA); Notice of Availability and Request for Comment

Polynt Composites USA Inc. is submitting a revised Safety Data Sheet (SDS) for phthalic anhydride to the EPA. They are requesting that the Agency use this updated SDS, which corrects an error regarding reporting thresholds, in its risk evaluation of the substance.

The Alliance for Automotive Innovation supports the EPA's draft risk evaluation but requests the inclusion of a 0.1% de minimis threshold for chemical reporting to align with industry standards and other federal rules. They also urge the EPA to expressly exclude replacement parts for complex durable goods from future risk management requirements to ensure the continued availability of essential vehicle components.
