PFAS: State-by-State Regulatory Update (July 2022 Revision)

Posted: July 28th, 2022

Authors: Kayla T. 

Given the current lack of all-encompassing federal environmental regulation around per- and polyfluoroalkyl substances (PFAS), states are taking it upon themselves to set their own standards amid growing public scrutiny.  With proposed house bills, rejections of bills, and other PFAS news popping up seemingly every day, it can be difficult to keep track of the regulatory climate and obligations.  ALL4 is here to help.

Note: This information is current as of July 28, 2022.

First to level-set, several key PFAS regulations currently at the federal level are presented below in Table 1.

Table 1
Summary of Key Federal PFAS Regulations

Category Subcategory Regulation
Water Drinking Water


Health Advisory Level (HAL) of 0.004 parts per trillion (ppt) for perfluorooctanoic acid (PFOA), 0.02 ppt for perfluorooctane sulfonate (PFOS), 10 ppt for hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt (together referred to as ‘‘GenX chemicals’’), and 2,000 ppt for perfluorobutane sulfonic acid and its related compound potassium perfluorobutane sulfonate (PFBS).


Note:  HALs are not enforceable.  U.S. Environmental Protection Agency (U.S. EPA) is moving forward to implement enforceable drinking water maximum contaminant levels (MCLs) for PFOA and PFOS.  U.S. EPA is also evaluating additional PFAS beyond PFOA and PFOS and considering actions to address groups of PFAS.  The proposed MCLs are anticipated in Fall 2022, but an enforceable limit does not exist at this time.

Published the final fifth Unregulated Contaminant Monitoring Rule (UCMR 5) which will require sample collection for 29 PFAS between 2023 and 2025.
National Pollutant Discharge Elimination System (NPDES) U.S. EPA issued a memo to agency water program directors which details how the U.S. EPA will address PFAS discharges in EPA-issued NPDES permits and provides recommended PFAS-related permit language.
Air N/A There are no proposed or promulgated standards at this time.
Other Toxic Release Inventory (TRI) Section 7321 of the National Defense Authorization Act for Fiscal Year 2020 (NDAA), which was passed in December 2019, immediately added 172 PFAS to the list of chemicals covered by the TRI and provided a framework for additional PFAS to be added to TRI on an annual basis.  This list became effective January 1, 2020, with the first PFAS Form Rs required by July 1, 2021.  Eight additional PFAS have been added to the TRI list since then, bringing the current total to 180.
Aqueous Film Forming Foam  (AFFF) The Department of Defense (DOD) is phasing out AFFF and prohibits the use of AFFF during training exercises at military sites.
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Added Regional Screening Levels (RSL) for PFBS, GenX chemicals, PFOS, PFOA, perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS) for Superfund sites.  Note that RSLs are general screening levels, not cleanup standards.


Additionally, U.S. EPA has restarted the process of proposing to designate PFOA and PFOS as “hazardous substances”.

Resource Conservation and Recovery Act (RCRA) Initiated the process to propose adding PFOA, PFOS, PFBS, and GenX chemicals as “hazardous constituents” under Appendix VIII.  Additionally, proposed clarification that the RCRA Corrective Action Program has the authority to require investigation and cleanup for wastes that meet the statutory definition of hazardous waste, as defined under RCRA §1004(5).
Toxic Substances Control Act (TSCA) Proposed rule requiring all manufacturers (including importers) of PFAS in any year since 2011 to report information related to chemical identity, categories of use, volumes manufactured and processed, byproducts, environmental and health effects, worker exposure, and disposal.
Significant New Use Rule (SNUR) Finalized for PFOA and PFOA-related chemicals.  The SNUR requires notification from anyone who begins or resumes the manufacturing, including importing, or processing of these chemicals.  The SNUR addresses risks from products like carpets, furniture, electronics, and household appliances.

The following maps provide a high-level summary of what states are currently doing in terms of water, air, and other (e.g., AFFF, waste, consumer goods, remediation) PFAS-related regulations.  This does not include any litigation, consent decrees, action plans/task forces, or investigative sampling.
