EPA Receives Manufacturer Requests for Risk Evaluations of DIDP and DINP

Lynn L. Bergeson

On June 14, 2019, the U.S. Environmental Protection Agency (EPA) announced that on May 24, 2019, EPA received manufacturer requests for EPA to conduct risk evaluations of diisodecyl phthalate (DIDP) from ExxonMobil Chemical Company and diisononyl phthalate (DINP) from ExxonMobil Chemical Company, Evonik Corporation, and Teknor Apex, both through the American Chemistry Council’s High Phthalates Panel.  EPA states that both DIDP and DINP belong to a family of chemicals commonly referred to as phthalates, which are used as plasticizers in the production of plastic and plastic coatings to increase flexibility and were identified in the 2014 Update to the Toxic Substances Control Act (TSCA) Work Plan.

Within 15 business days of receiving a facially complete request (i.e., submission appears to be consistent with rule requirements), EPA states that it must notify the public of receipt of this request under 40 C.F.R. Section 702.37(e)(2); and within 60 business days of receipt of a facially complete request, EPA will submit for publication the receipt of the request in the Federal Register, open a public docket for the request, and provide no less than 45 calendar days for public comment.  After the comment period closes, EPA has up to 60 days to either grant or deny the request to conduct a risk evaluation under 40 C.F.R. Section 702.37(e)(6).  More information on Manufacturer Requests is available on EPA’s website.
