Three former EPA officials are renewing calls for the agency to use TSCA authority to order Chemours to conduct new toxicity testing of dozens of per- and polyfluoroalkyl substances (PFAS), pushing back on claims from EPA’s chemicals chief that the data “already exist” even as they sue over the agency’s failure to order the tests.
A strategy the EPA is using to decide what scientific data it will use to decide whether a chemical’s potential to harm people or the environment is so great it must be regulated could ignore potential harms, academic scientists and an environmental group said Tuesday.
A few days after the inauguration of President Joe Biden, Michal Freedhoff settled into her cramped home office in a suburb of Washington, D.C., to get to work as the nation’s new top chemical regulator.
