Takeaways from ACI’s 3rd Annual Summit on PFAS Regulation, Compliance and Litigation

June 2, 2026

Reading Time : 2 min

I was honored to present once again at the American Conference Institute’s (ACI) Annual Summit on PFAS Regulation, Compliance and Litigation, this year as part of a great state regulatory panel. Below are some thoughts from the conference:

  • We now have a (slightly) greater sense of the per- and polyfluoroalkyl substances (PFAS) TSCA Reporting requirement deadline. U.S. Environmental Protection Agency (EPA) Deputy Administrator David Fotouhi anticipates the underlying rulemaking will go final just before the end of the year, which lines up well with the proposed January 31 reporting timeline (at most 60 days after the rule goes final). Fotouhi also noted that the Agency intends to make reporting more practicable and less duplicative, reducing requirements in the final rule.

  • Speaking of reporting, Minnesota Pollution Control Agency head Katrina Kessler stated that the State remains on track to implement a September deadline for its own reporting rule. To date, approximately 40 entities have filed close to 700 reports, which Kessler takes as evidence that no further delay is necessary. Kessler stated the Agency has “no idea” how many reports they will receive in total.

  • Two other items of note from Minnesota. First and foremost, Kessler indicated in a private conversation that she does not expect to stay on past 2026. Second, Kessler stated that the Agency will spot-check products at online and physical retailers for PFAS content to ensure compliance as she does not expect many companies to test on their own. That said, she does expect companies seeking a currently unavoidable use (CUU) determination to test their products and report on PFAS content in their applications.

  • While on testing, New Mexico’s PFAS-only attorney at the state attorney general’s office, Greg Smithkier, stated that until New Mexico’s Environment Department has its own testing team (in progress), they will rely upon nongovernmental organizations (NGOs) and environmental groups to conduct spot checking. He also stated that in response to a legislative directive, New Mexico will re-evaluate its exemptions for fluoropolymers in a preliminary report this year, to be followed by a final document, August 2027. With respect to reporting, Smithkier noted that New Mexico will employ the same system as Minnesota, and that publicly available reporting in other jurisdictions may allow for a waiver from the requirements.

Head of Akin’s environment & natural resources practice David Quigley is quoted by Chemical Watch News & Insight in an article titled, “New Mexico to use PRISM platform for PFAS reporting,” discussing New Mexico’s decision to adopt the Per- and Polyfluoroalkyl Substances (PFAS) Reporting Information System for Manufacturers (PRISM) for PFAS disclosures already used in Minnesota. The article draws on remarks David delivered at the PFAS Global Conference hosted by Chemical Watch, where he discussed the PFAS regulatory environment.

After the U.S. Environmental Protection Agency (EPA) delayed the submission period for its one-time per- and polyfluoroalkyl substances (PFAS) reporting requirement under the Toxic Substances Control Act, Minnesota just extended its own (previously extended) PFAS products reporting deadline from July 1, 2026, to September 15, 2026. The Minnesota Pollution Control Agency cited challenges in collecting and submitting data under the state’s reporting rule, adopted in December 2025, as necessitating the delay. That rule requires manufacturers of intentionally added PFAS-containing products to submit a description of each product and the concentration and function of PFAS in it. Manufacturers unable to meet the new deadline may request a single, 90-day extension, which would extend reporting to December 2026. The Agency notes that 18 companies submitted reports ahead of the original deadline, data from which (except for protected trade secrets) is now publicly available. Given the fluidity of the rules and the deadlines, we continue to advise submitting closer to the (now later) end of the reporting period.

On April 9, 2026, the Environmental Protection Agency (EPA) announced a long-anticipated delay in the reporting window for the per- and polyfluoroalkyl substances (PFAS) reporting rule under the Toxic Substances Control Act (TSCA). In October 2023, EPA imposed a one-time requirement under TSCA on entities that manufactured (including imported) PFAS or PFAS containing products between 2011 and 2022 to submit to EPA information regarding PFAS exposure and environmental and health effects. After two extensions due to delays in developing the web-based reporting portal, the reporting window under the rule was set to open on April 13, 2026, and close on October 13, 2026. As the opening date approached, EPA proposed a partial rollback of the rule that would both exempt certain categories of PFAS from the reporting requirements and change the reporting period (a prior PFAS Press blog post discusses the proposed rollback) but until today it had not formally cancelled the original start date. With the announcement, EPA resolved the uncertainty, confirming that reporting will not commence on April 13 and instead will begin only 60 days after the revised rule becomes effective (although questions still remain as to whether EPA will shorten the reporting window from the original six months to the proposed three months). EPA plans to issue a final rule on reporting later this year, with updated guidance and reporting tools accompanying the revised requirements.
