U.S. EPA Updates Regional Screening Levels to Add Five New PFAS Chemicals
On May 18, 2022, U.S. EPA updated its Regional Screening Level tables to include five new per- and polyfluoroalkyl substances (PFAS). The five new PFAS compounds added to the RSL tables are hexafluoropropylene oxide dimer acid and its ammonium salt (HFPO-DA – sometimes referred to as GenX chemicals), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic… Continue reading

U.S. EPA’s Addition of 1-BP to CERCLA Hazardous Substance List Likely Precursor to Similar Actions on PFAS
On April 8, 2022, U.S. EPA added the industrial solvent 1-bromopropane (1-BP) to its list of CERCLA hazardous substances; this listing was triggered by U.S. EPA’s decision to add 1-BP to the Clean Air Act’s list of hazardous air pollutants in January 2022. Continue reading

U.S. EPA Announces Plan to Tighten PFAS Reporting Requirements
In connection with the release of its 2020 Toxics Release Inventory (TRI) National Analysis which evidenced a 10% decline in environmental releases of TRI chemicals between 2019 and 2020, U.S. EPA also announced that it intends to initiate a rulemaking later in 2022 that will, among other things, remove the de minimis exemption for reporting… Continue reading

PFOA and PFAS Take Another Step Towards Becoming Full-Fledged Members of the CERCLA Family of Hazardous Substances
On January 10, 2022, U.S. EPA forwarded a proposed rule that seeks to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as “hazardous substances” under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Although not unexpected since this was a key element of U.S. EPA’s PFAS Strategic Roadmap, U.S. EPA’s proposed rule is unique… Continue reading

U.S. EPA Finalizes Fifth UCMR—PFAS Remain in the Regulatory Bullseye
On December 20, 2021, U.S. EPA finalized its Fifth Unregulated Contaminant Monitoring Rule (UCMR) that will require public water systems (PWS) to collect monitoring data for 29 per- and polyfluoroalkyl substances (PFAS) and lithium in drinking water. Continue reading

New PFAS Additions to the Proposition 65 List
Over the past week, several new per- and polyfluoroalkyl substances (PFAS) have been added to California’s Proposition 65 list. In March 2021, California’s Office of Environmental Health Hazard Assessment (OEHHA) selected perfluorooctane sulfonate (PFOS) and its salt and transformation and degradation precursors for evaluation by California’s Carcinogenic Identification Committee (CIC). OEHHA also selected perfluoronanoic acid (PFNA) and… Continue reading

U.S. EPA Releases its PFAS Strategic Roadmap
On Monday, October 18, 2021, U.S. EPA released its PFAS Strategic Roadmap (Roadmap) outlining the agency’s three-year strategy for addressing per- and polyfluoroalkyl substances (PFAS). The Roadmap notes that U.S. EPA cannot solve the problem of “forever chemicals” by tackling only one route of exposure or one use at a time. Continue reading

TSCA Articles Regulations—U.S. EPA Course Reversal?
In prepared remarks from U.S. EPA chemicals chief Michael Freedhoff that were presented at the Product Stewardship Society’s annual meeting, Freedhoff clearly articulated an intent by the Agency to reverse course and aggressively seek to regulate finished articles under the Toxic Substances Control Act (“TSCA”).
