U.S. EPA Takes Additional Steps to Evaluate and Restrict PFAS in Pesticides

On September 13, the U.S. Environmental Protection Agency (EPA) published a notice proposing to remove 12 per- and polyfluoroalkyl substances (PFAS) from its list of inert ingredients approved for use in regulated pesticide products. The 12 PFAS are listed below. According to EPA’s review, none of the 12 PFAS are being used as inert ingredients in any registered pesticide products; however, removing chemicals from EPA’s list of approved inert ingredients ensures that any future proposed use of these PFAS as inert ingredients would require substantiation with data (including, among other things, studies evaluating potential carcinogenicity, genotoxicity, adverse reproductive effects) and approval by EPA.

EPA Takes Two New Actions on PFAS

The U.S. Environmental Protection Agency (EPA) took two important actions in late December 2021 related to per- and polyfluoroalkyl substances (PFAS), a class of chemicals receiving increasing legislative and regulatory scrutiny in recent years. The two actions relate to drinking-water monitoring data and to toxicity and human-health testing data. (more…)

Biden Administration Issues Executive Order on Sustainable Procurement

On December 8, 2021, the Biden Administration issued an executive order seeking to leverage United States procurement power to promote investment in clean energy. The order sets out the following five goals: “100 percent carbon pollution-free electricity (CFE) by 2030, at least half of which will be locally supplied clean energy to meet 24/7 demand; 100 percent zero-emission vehicle (ZEV) acquisitions by 2035, including 100 percent zero-emission light-duty vehicle acquisitions by 2027; [n]et-zero emissions from federal procurement no later than 2050, including a Buy Clean policy to promote use of construction materials with lower embodied emissions; [a] net-zero emissions building portfolio by 2045, including a 50 percent emissions reduction by 2032; and [n]et-zero emissions from overall federal operations by 2050, including a 65 percent emissions reduction by 2030.” (more…)

EPA to Initiate Rulemakings Addressing PFAS Under Resource Conservation and Recovery Act as “Hazardous Constituents”

The U.S. Environmental Protection Agency (EPA or Agency) announced that it will initiate two separate rulemakings to address PFAS (per- and polyfluorinated substances) under the federal Resource Conservation and Recovery Act (RCRA) — the law that provides EPA with authority to address hazardous waste from “cradle to grave.” EPA announced these policy proposals in response to a petition submitted to Administrator Michael Regan by New Mexico Gov, Michelle Lujan Grisham on June 23 requesting that the Agency take regulatory action to list PFAS either collectively or individually as “hazardous waste” under Subtitle C of the Act.

PFAS Strategic Roadmap: EPA Releases Human Health Toxicity Assessment for “GenX” PFAS Chemicals

The U.S. Environmental Protection Agency (EPA or Agency) has released its final human health toxicity assessments for a subgroup of PFAS chemicals known as GenX (i.e., hexafluoropropylene oxide dimer acid and its ammonium salt). GenX is the trade name for a set of chemicals intended to replace another PFAS chemical called PFOA (perfluorooctanoic acid). (more…)
