Inactive PFAS rule activated: EPA must review before use
The Environmental Protection Agency (EPA) continues to add regulations to per- and polyfluoroalkyl substances (PFAS). The new rule finalized in January 2024 prevents facilities from using inactive PFAS before EPA reviews the planned use and makes a risk determination.
This significant new use rule (SNUR) applies to the 329 PFAS designated as inactive on the Toxic Substances Control Act (TSCA) Chemical Substance Inventory and aren’t yet subject to an existing SNUR. An inactive PFAS hasn’t been manufactured (including imported) or processed in the U.S. since June 21, 2006.
What are PFAS?
Also called “forever chemicals,” PFAS are a group of thousands of manufactured chemicals that are used widely in industry and consumer products. Many take a long time to break down and build up over time. They’re found nearly everywhere in water, air, soil, and consumer products, such as nonstick cookware, food packaging, clothing, and shampoo.
Some studies suggest that exposure to PFAS may lead to health issues. However, research continues since much remains unknown about the chemical substances. EPA regulates PFAS to prevent them from entering air, land, and water at levels that may harm human health and the environment.
What are the new SNUR requirements?
Under TSCA, EPA can determine that a certain use of a chemical substance is a “significant new use” and require anyone who wants to use the chemical substance for that purpose to first notify the agency. EPA will then conduct a review and risk determination. The new SNUR requires EPA to conduct reviews and risk determinations of the inactive PFAS before they can be used again.
If your facility wants to manufacture (including import) or process an inactive PFAS, notify EPA at least 90 days through a significant new use notice before beginning use. Once EPA receives the notification, the agency will:
- Conduct a review to determine whether the new use presents an unreasonable risk to human health or the environment, and
- Make a risk determination.
If the new use doesn’t present an unreasonable risk and EPA makes an affirmative determination, your facility can use the PFAS. However, if the new use presents an unreasonable risk, the agency must first regulate the activity before you can use the PFAS.
What are other recent regulations of PFAS?
Over the past three years, EPA has implemented the 2021–2024 PFAS Strategic Roadmap, the agency's comprehensive strategy to address the risks of PFAS exposure and contamination through specific regulatory actions. The agency focuses on three directives: researching the forever chemicals, restricting the release of them into the environment, and cleaning up PFAS-contaminated sites.
This final rule joins EPA’s other actions taken via the PFAS Strategic Roadmap. These include:
- Designating all PFAS as chemicals of special concern, eliminating the de minimis reporting exemption that allowed facilities to avoid reporting PFAS used in small quantities;
- Removing the de minimis supplier notification exemption for all listed chemicals of special concern to require suppliers to notify users of any chemicals of special concern present in mixtures; and
- Requiring all manufacturers (including importers) of PFAS and PFAS-containing articles in any year since 2011 to report information on uses, production volumes, disposals, exposures, and hazards.
How does this affect you?
If your facility manufactures (including imports) or processes PFAS, you’ll likely face more regulations and reporting requirements. So, how can you remain compliant? Stay informed of EPA’s latest regulatory actions regarding PFAS. Consider these best practices:
- Check EPA’s final rules published in the Federal Register regularly for PFAS-related regulations.
- Review EPA’s proposed rules (also published in the Federal Register) to prepare for potential upcoming regulations.
- Identify any applicable state PFAS regulations.
Also, consider the proactive approach to search for safer alternative chemicals you can substitute for PFAS. It’s vital to choose chemicals already reviewed by EPA to ensure the alternative option doesn’t also present an unreasonable risk to human health and the environment.
Key to remember: EPA continues to strengthen its regulation of PFAS. A new rule now prevents facilities from using any of the 300+ inactive PFAS before EPA conducts a risk determination and, if necessary, regulates the activity.
