EPA has proposed to add a category for diisononyl phthalate (DINP)
to the list of toxic chemicals subject to annual reporting under the Emergency Planning and Community Right-To-Know Act (EPCRA) Toxics Release Inventory (TRI) regulations.
EPA will accept public comments on the proposed rule until October 7, 2022.
Sometimes referred to as SARA 313 or Form R reporting, section 313 of EPCRA requires facilities that manufacture, import, process, or use certain chemicals to report annually to EPA about their activities if they exceed regulatory thresholds.
From the proposed rule:
“EPA is now proposing to list the DINP category based on our preliminary conclusion that it is reasonably anticipated to cause cancer and serious or irreversible chronic health effects including developmental, kidney, and liver toxicity.”
DINP is a family of colorless, oily liquids used as plasticizers, particularly in the production of polyvinyl chloride (PVC).
A petition to add DINP to the EPCRA 313 reporting program was submitted in 2000, prompting EPA to complete a hazard assessment and propose a rule to add the category to the list of reportable substances. EPA revised its hazard assessment based on comments received and requested further comment with a notice of data availability (NODA) in 2005.
The rulemaking effort was never finalized. Earlier this year, a settlement was reached
which requires EPA to add DINP to the TRI list no later than January 31, 2023, or officially withdraw the rulemaking effort that began in 2000.
