General PFAS News & Updates

In September, EPA set forth its latest draft plan for setting guidelines for PFAS limitations in industrial wastewater in certain industries, and October brought public comments on the draft.  Among EPA’s next steps in its September 2021 Preliminary Effluent Guidelines Program Plan 15 (Preliminary Plan 15) are:

  • a rulemaking process to set new limitations on

On September 23, 2021, the Pennsylvania Independent Regulatory Review Commission (IRRC) approved a final form rulemaking that revises the Pennsylvania Department of Environmental Protection’s (PADEP) regulations that implement that Land Recycling and Environmental Remediation Standards Act (Act 2).

As we discussed in a previous post, this regulatory revision includes the following new groundwater

The process to revise regulations in Pennsylvania is often long and involved, and the Pennsylvania Department of Environmental Protection’s (PADEP) revision to its Act 2 Chapter 250 regulations to incorporate cleanup standards for three per- and polyfluoroalkyl substances (PFAS) has proved to be no exception.  PADEP first published its regulatory proposal in the Pennsylvania Bulletin

At its July 29, 2021 meeting, the Pennsylvania Department of Environmental Protection (“Department”)’s Public Water System Technical Assistance Center (TAC) Board voted to recommend that the Department proceed with a draft proposed rulemaking to set maximum contaminant levels (MCLs) in drinking water for certain PFAS compounds.  The Department has proposed drinking water levels of 14

On March 24, 2021, the Pennsylvania Department of Environmental Protection (PADEP) announced that it issued an National Pollutant Discharge Elimination System (NPDES) permit to the Biddle Air National Guard Base (ANGB) (formerly the Horsham Air Guard Station) containing discharge limits of 70 parts per trillion (ppt) for the combined concentration of perfluorooctanoic acid (PFOA)

The march toward regulation of PFAS in Pennsylvania continues (see our recent post on statewide public water system sampling results), with the release of final data from sampling conducted in September 2019 of surface waters throughout the Commonwealth.  The study, a collaboration among the U.S. Geological Service (“USGS”), the Susquehanna River Basin Commission, and

The California Office of Environmental Health Hazard Assessment (OEHHA) is expanding its review of potential substances to add to its Proposition 65 list of chemicals that cause cancer.

Earlier this year, the state announced it intended to add perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) to the list. After the public comment periods ended for

In the March 3, 2021 Federal Register, EPA issued its final regulatory determinations for substances on the fourth Drinking Water Contaminant Candidate List (“CCL 4”). Under the federal Safe Drinking Water Act, EPA is required to publish a list every five years of chemicals that are known or suspected to be found in public drinking

We’ve discussed in our previous posts the process that EPA will likely use to designate PFOA and PFOS as “hazardous substances,” how that designation will impact responsible parties, and what effects it may have on current EPA-lead investigations and remediations. In this article we discuss how the process may impact states that are
