The U.S. Environmental Protection Agency (EPA) took an important step toward regulating PFAS (per- and poly-fluoroalkyl substances) on September 6, 2022 when it published a Notice of Federal Rulemaking to begin the process of listing two PFAS as hazardous substances under Section 102(a) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, also known as the “Superfund” law). Specifically, perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), both of which have been identified as health hazards since 2016, are being reviewed. Comments on the proposal are due by October 6, 2022.

The group of chemicals known as PFAS (per- and poly-fluoroalkyl substances) are high on the federal regulatory agenda for 2022, as implementation of EPA’s “PFAS Strategic Roadmap” proceeds. One potential consequence will be new additions to California’s “Prop 65 List” of chemicals known to cause cancer or reproductive harm. Already, two PFAS substances are subject to Prop 65 warning and labeling requirements (PFOA and PFOS), with a third (PFNA) subject to enforcement starting in 2023. New federal Health Advisory Levels (HALs) announced on June 15, 2022 may provide the basis to add another two PFAS to the list (PFBS and GenX).…
The U.S. District Court for the District of Arizona on August 30 vacated the 2020 Navigable Waters Protection Rule (NWPR) that redefined “waters of the United States” for purposes of Clean Water Act jurisdiction, effectively reinstating the definition in effect prior to 2015. Under that prior definition, many ephemeral streams and isolated wetlands that were not subject to federal jurisdiction under the NWPR will again be subject to case-by-case determinations of their status. The case, Pasqua Yaqui Tribe v. EPA, CV-20-00266-TUC-RM (D. Ariz.), is one of several challenging the NWPR, and the outcome leaves unanswered questions about the scope of the court’s ruling and the potential for inconsistent regulations across the nation.

The decades-long battle over organic certification of hydroponically grown foods is poised for resolution, with the Ninth Circuit Court of Appeals set to decide an appeal by the Center for Food Safety (CFS) in a case that seeks to block certification of foods not grown in soil. On May 19, 2021, CFS filed an appeal asking the Ninth Circuit to reverse a district court decision upholding the U.S. Department of Agriculture’s determination that hydroponically grown foods are eligible for certification under the National Organic Program (NOP). The outcome of the appeal could have significant implications both for hydroponically grown fruits and vegetables and for other soil-less crops, including mushrooms and sprouts.
