On July 13, 2022, The Chemours Firm FC, LLC (“Chemours”) submitted a Petition for Critique with the 3rd Circuit U.S. Court of Appeals complicated the United States Environmental Protection Agency (“EPA”)’s Wellbeing Advisory Degree (“HAL”) of 10 ppt for HFPO Dimer Acid, a.k.a. GenX, alleging that the HAL is based on a “deeply flawed, scientifically unsound toxicity assessment.”  As mentioned in our previous report, EPA declared on June 15, 2022 its issuance of the GenX HAL, alongside with a HAL for three other PFAS.

Chemours has challenged the GenX HAL on a number of bases, such as the assertion that the GenX toxicity assessment is flawed because it assumed that consuming drinking water accounts for only 20% of a person’s exposure to GenX chemical substances in contradiction of a wide quantity of info in EPA’s possession.  Chemours also argues that because of to EPA’s assumption that 80% of publicity to GenX chemical compounds is from resources other than drinking h2o, EPA does not have the authority below the Safe and sound Drinking Drinking water Act to situation the HAL.  Chemours more argues that Congress unsuccessful to offer EPA with any direction or constraints with regards to wellness advisories, and as a outcome, the Safe and sound Drinking H2o Act’s delegation of authority to EPA to challenge well being advisories violates the constitutional nondelegation doctrine and is unconstitutional.  In earning this argument, Chemours may be encouraged by the consequence in the recent Supreme Court circumstance West Virginia v. EPA, No. 20-1530 (June 30, 2022). To prevail over the obstacle that a HAL could not constitute a last agency action that can be appealed, Chemours asserts that the HALs are regulatory in mother nature for the reason that they have considerable authorized implications in numerous contexts like use by EPA, and in accordance to Chemours, required adoption in above 20 states.  Remain tuned for even further updates after the briefing takes place in this subject.
