DINP listed in US TRI by EPA
On 13 July 2023, the U.S. Environmental Protection Agency (EPA) finalised a rule that adds a diisononyl phthalate (DINP) including branched alkyl di-esters of 1,2 benzenedicarboxylic acid in which alkyl ester moieties contain a total of nine carbons category to the Toxics Release Inventory (TRI) reporting requirements. This change was made under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA). This rule will become effective on 12 September 2023. See US EPA’s announcement.
The TRI is a specific US-regulation with no effect to other regions. It is not a restriction of DINP but rather establishes further a reporting requirement. The American Chemistry Council’s (ACC) disagrees with EPA listing DINP on the TRI. For further details, please read the American Chemistry Council’s reaction.
This does not affect the status of the regulation on DINP in the EU, including ECHA RAC’s conclusion of no classification to this substance.
