The Natural Resources Defense Council (NRDC) is preparing to sue the EPA over its failure to regulate the dangerous chemical hydrogen fluoride (HF) using the same legal strategy that FAN employed in our recent fluoride lawsuit win over the EPA.

NRDC submitted a legal petition to the EPA on February 11, 2025, under the Toxic Substances Control Act (TSCA). On May 12, 2025, the EPA denied the petition and refused to start a regulatory process to eliminate the unreasonable risk that refineries’ use of HF presents to public health and the environment.

Much like FAN did in 2017, NRDC “now has the option of going to court and asking a judge to rule that refinery use of hydrogen fluoride presents an unreasonable risk, which the EPA must eliminate through regulation.

NRDC is interested in talking to people living near HF-using refineries, asking for their stories on the matter. are interested in talking to people living near HF-using refineries, asking for their stories on the matter.”
