"The EPA is also currently proposing a rule to rescind the regulatory determinations and associated regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index mixtures of these three PFAS and PFBS. The public hearing for that proposed rulemaking will be held sequentially with this proposed PFOA and PFOS compliance extension public hearing. For those interested in attending and/or providing verbal public comment on both rules, there is a combined registration process. However, please note that each separate rule proposal has an individual rulemaking docket for written comments. Please ensure any written comments are submitted to the specific docket associated with your comments."
