EPA has issued its second round of Test Orders under its National PFAS Testing Strategy. The test orders require companies to conduct and submit testing on trifluoro (trifluoromethyl) oxirane (HFPO) (CASRN 428-59-1), a PFAS substance used in making plastics. According to EPA’s Chemical Data Reporting (CDR) database, more than 1,000,000 points of HFPO are manufactured each year. EPA has concluded, using existing hazard and exposure data, that HFPO may present an unreasonable risk of injury to health or the environment, finding that exposure may result in neurotoxicity, reproductive effects, and cancer. The Tier 1 testing will address human health from exposure via inhalation and hydrolysis. Tier 2 testing, if required, will look at reproductive toxicity, developmental neurotoxicity, and carcinogenicity.
The companies that are subject to the test order include The Chemours Company, DuPont De Nemours Inc., E.I. du Pont de Nemours and Company, and 3M Company. These companies are required to submit the results of testing data to EPA within 415 days of the effective date of the order. All data produced from this test order will subsequently be published on EPA’s website.
