Addition of Diisononyl Phthalate Category Proposed Rule
On this page:
In September 2000, in response to a petition filed under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA), EPA proposed to add a diisononyl phthalate (DINP) category to the list of toxic chemicals subject to the reporting requirements under EPCRA Section 313 and Section 6607 of the Pollution Prevention Act (PPA). EPA proposed to add this chemical category based on DINP’s carcinogenicity and liver, kidney, and developmental toxicity.
On February 29, 2000, EPA received a petition from the Washington Toxics Coalition (WTC) requesting EPA to add DINP to the list of toxic chemicals subject to reporting under EPCRA Section 313 and PPA Section 6607 (also known as the Toxics Release Inventory). The WTC contended that DINP causes cancer, systemic toxicity, developmental toxicity, and endocrine disruption, and therefore should be added to the TRI chemical list. The petitioner alleged that DINP is ‘‘a dangerous phthalate ester that is used as the principal plasticizer in toys and many other products used by children and adults.’’ WTC also claimed that ‘‘DINP has been shown to cause cancer and other very serious toxic effects."
After a review of the available data, EPA preliminarily determined that there was sufficient evidence for including this category of DINP on the EPCRA Section 313 chemical list, because the DINP category can reasonably be anticipated to cause carcinogenicity and liver, kidney, and developmental toxicity.
