Current and former EPA employees say the agency is not defining some fluorinated chemicals used in pesticides as PFAS at a time when research has discovered their widespread use in agricultural products. The agency also excludes some “ultra short chain” PFAS refrigerants, which are defined as PFAS by the European Union but not the toxics office, said Tim Whitehouse, a former EPA attorney now with the Public Employees for Environmental Responsibility nonprofit.
He said the stricter regulations in Europe have forced the industry away from the kind of PFAS refrigerants produced by Chemours, a chemical manufacturer with a plant in North Carolina. Chemours opposes defining the refrigerants as PFAS “because it is going to destroy their market” as it has in Europe, Whitehouse added.
