Practical EHS Tips, News & Advice. Updated Daily.
Back to Basics is a weekly feature that highlights important but possibly overlooked information that any EHS professional should know. This week, we examine per- and polyfluoroalkyl substances and actions to take to reduce the risks associated with PFAS. The U.S. Environmental Protection Agency (EPA) is taking several steps to address per- and polyfluoroalkyl substances […]
On March 14, 2023, the Biden-Harris administration announced its proposal for a first-ever National Primary Drinking Water Regulation (NPDWR) for six per- and polyfluoroalkyl substances (PFAS). The legally proposed enforceable limits are 4 parts per trillion (ppt) for perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). If finalized as proposed, public water systems (PWSs) have 3 […]
The EPA has proposed a Significant New Use Rule (SNUR) that would prevent companies from starting or resuming the manufacturing, processing, or use of an estimated 300 per- and polyfluoroalkyl substances (PFAS) that have not been made or used for many years without a complete EPA review and risk determination. In the past, these chemicals, […]
Industry will need to stay on its toes to remain in compliance with the shifting and complex reporting requirement for perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the regulatory pipeline for 2023, 2024, and beyond. And some states, such as Maine, are bringing rules into effect to ban these chemicals. These requirements are negatively impacting consumer […]
The EPA unveiled new website tools, the PFAS Analytic Tools, this month. Designed to help the “public, researchers, and other stakeholders better understand potential PFAS sources in their communities,” the tools provide “multiple sources of information in one spot with mapping, charting, and filtering functions,” which allows the public to see where testing has been […]
The EPA’s proposed rulemaking to designate two per- and polyfluoroalkyl substances (PFAS)—perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers—as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) hit a snag after its Office of Management and Budget (OMB) review. The review identified the proposal as “economically […]
On July 18, 2022, the EPA published the final rule “Implementing Statutory Addition of Certain Per- and Polyfluoroalkyl Substances (PFAS) to the Toxics Release Inventory (TRI) Beginning with Reporting Years 2021 and 2022.” The rule adds five PFAS to the toxic chemicals list that must be reported under the Pollution Prevention Act (PPA) and the […]
On June 15, 2022, the EPA released four drinking water health advisories for per- and polyfluoroalkyl substances (PFAS) in the latest action under President Joseph Biden Jr.’s action plan to deliver clean water and EPA Administrator Michael Regan’s PFAS Strategic Roadmap. Drinking water health advisories indicate a level of a contaminant below which adverse health […]
On June 6, 2022, the EPA issued the first Toxic Substances Control Act (TSCA) test orders to the Chemours Company, DuPont De Nemours Inc., National Foam Inc., and Johnson Controls Inc. The orders require the companies to conduct and submit testing on per- and polyfluoroalkyl substances (PFAS). In October 2021, the Agency announced its PFAS […]
On April 28, the EPA announced three actions to increase public protection against per- and polyfluoroalkyl substances (PFAS) in our nation’s waters. The actions “advance progress under the Biden-Harris Administration’s Plan to Combat PFAS Pollution by improving methods to detect PFAS in water, reducing PFAS discharges into our nation’s waters, and protecting fish and aquatic […]
