The EPA is also proposing to rescind all associated regulatory provisions currently codified in the EPA's 2024 PFAS National Primary Drinking Water Regulations (NPDWR) exclusive to these PFAS that were promulgated pursuant to the regulatory determinations that the EPA is now proposing to rescind, including the final Maximum Contaminant Levels (MCLs) that would have required monitoring, and where necessary, treatment by public water systems (PWSs). This proposed action is necessary to correct the unlawful procedure under which these regulations were promulgated. Under the EPA's prior interpretation, the EPA proposed and finalized regulatory determinations and regulations for these PFAS simultaneously and in tandem. Under the best reading of the statute, the EPA is not authorized to take such actions simultaneously and therefore, the Agency proposes to rescind those regulatory determinations, Maximum Contaminant Level Goals (MCLGs) and associated portions of the 2024 PFAS NPDWR.

After consideration of public comment and consistent with the provisions set forth under the Safe Drinking Water Act (SDWA), the EPA is finalizing NPDWRs for these six PFAS. Through this action, the EPA is finalizing MCLGs for PFOA and PFOS at zero. Considering feasibility, the EPA is promulgating individual Maximum Contaminant Levels (MCLs) for PFOA and PFOS at 4.0 nanograms per liter (ng/L) or parts per trillion (ppt). The EPA is also finalizing individual MCLGs and is promulgating individual MCLs for PFHxS, PFNA, and HFPO-DA at 10 ng/L. In addition to the individual MCLs for PFHxS, PFNA, and HFPO-DA, in consideration of the known toxic effects, dose additive health concerns and occurrence and likely co-occurrence in drinking water of these three PFAS, as well as PFBS, the EPA is finalizing a Hazard Index (HI) of 1 (unitless) as the MCLG and MCL for any mixture containing two or more of PFHxS, PFNA, HFPO-DA, and PFBS. Once fully implemented, the EPA estimates that the rule will prevent thousands of deaths and reduce tens of thousands of serious PFAS-attributable illnesses.","document_number":"2024-07773","html_url":"https://www.federalregister.gov/documents/2024/04/26/2024-07773/pfas-national-primary-drinking-water-regulation","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-04-26/pdf/2024-07773.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-07773.pdf?1714049126","publication_date":"2024-04-26","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"excerpts":"polyfluoroalkyl substances (<span class=\"match\">PFAS</span>) in drinking water.

EPA is not proposing any changes to the scope of reporting under TSCA. EPA has concluded that a change to the submission period is necessary and in the public interest as the reporting application being developed to collect this data will not be fully functional by November 2024. The proposed revision of the submission period would facilitate compliance with the rule and help ensure that the collection includes accurate data on manufactured PFAS in the United States. EPA thus believes the proposed amendments are necessary and does not expect to receive any adverse comments.

EPA's criteria for listing substances as hazardous constituents under RCRA require that they have been shown in scientific studies to have toxic, carcinogenic, mutagenic, or teratogenic effects on humans or other life forms. EPA reviewed and evaluated key toxicity and epidemiological studies and assessments for the nine PFAS to determine whether the available data for these PFAS meet the Agency's criteria for listing substances as hazardous constituents under RCRA. Based on EPA's evaluation, the above nine PFAS, their salts, and their structural isomers meet the criteria for being listed as RCRA hazardous constituents. As a result of this proposed rule, if finalized, when corrective action requirements are imposed at a facility, these PFAS would be among the hazardous constituents expressly identified for consideration in RCRA facility assessments and, where necessary, further investigation and cleanup through the RCRA corrective action process at RCRA treatment, storage, and disposal facilities.","document_number":"2024-02324","html_url":"https://www.federalregister.gov/documents/2024/02/08/2024-02324/listing-of-specific-pfas-as-hazardous-constituents","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-02-08/pdf/2024-02324.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-02324.pdf?1707313515","publication_date":"2024-02-08","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"excerpts":"environmental justice concerns. \n VIII.
