In this action, the EPA is proposing to set the perchlorate MCLG at 0.02 mg/L (20 [micro]g/L). The EPA is also proposing and taking comment on setting an enforceable Maximum Contaminant Level (MCL) for perchlorate at 0.02 mg/ L (20 [micro]g/L), 0.04 mg/L (40 [micro]g/L), or 0.08 mg/L (80 [micro]g/L). The EPA is also proposing requirements for water systems to conduct monitoring for perchlorate in drinking water, take mitigation actions if the level exceeds the MCL, provide information about perchlorate to their consumers through public notification and consumer confidence reports, and report to their respective primacy agency. The Administrator has determined that the benefits of this regulation would not justify the costs; however, the EPA is required to issue an NPDWR and MCLG for perchlorate in response to the D.C. Circuit's decision in NRDC v. Regan.","document_number":"2026-00021","html_url":"https://www.federalregister.gov/documents/2026/01/06/2026-00021/national-primary-drinking-water-regulation-for-perchlorate","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-01-06/pdf/2026-00021.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-00021.pdf?1767620710","publication_date":"2026-01-06","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":"perchlorate levels in their <span class=\"match\">drinking</span> <span class=\"match\">water</span>.

The EPA has determined that the State of Indiana's PWSS program regulations and the revisions thereto are no less stringent than the above corresponding federal regulations and thus give the Indiana Department of Environmental Management primary enforcement responsibility for the GWR, LCR-STR, LT2 ESWTR, and Stage 2 D/DBPR. Notice is also hereby given that the EPA has approved the State of Illinois' revisions to its PWSS program under SDWA for adoption of the Filter Backwash Recycling Rule (FBRR). The EPA has determined that the State of Illinois' PWSS Program regulations and the revisions thereto are no less stringent than the NPDWR and thus give the Illinois Environmental Protection Agency primary enforcement responsibility for the FBRR. These determinations on the Indiana and Illinois requests for approval of such primacy enforcement responsibility shall take effect in accordance with procedures described below, subject to timely substantial requests for public hearing. This approval action does not extend to public water systems in Indian Country.

The decision to regulate or not to regulate a contaminant is known as a regulatory determination. In most cases, the contaminants chosen for regulatory determination are selected from the most recent Contaminant Candidate List (CCL), which the SDWA requires the EPA to publish every five years. This document presents the preliminary regulatory determinations and supporting rationale for contaminants listed on the EPA's fifth CCL (CCL 5). Since the fourth round of regulatory determinations was published in March 2021, the EPA has made determinations to regulate per- and polyfluoroalkyl substances (PFAS), including individual determinations for three PFAS: perfluorononanoic acid (PFNA), perfluorohexanesulfonic acid (PFHxS), hexafluoropropylene oxide dimer acid and its ammonium salt (HFPO-DA, also known as GenX or GenX chemicals); and mixtures including two or more of these three PFAS and perfluorobutanesulfonic acid (PFBS). In April 2024, the agency issued a final National Primary Drinking Water Regulation that includes these four PFAS as well as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). In this Federal Register Notice (FRN), the EPA is making preliminary determinations not to regulate nine additional contaminants from CCL 5: 2-aminotoluene, cylindrospermopsin, ethoprop, microcystins, molybdenum, permethrin, profenofos, tebuconazole and tribufos. The EPA requests public comment on these preliminary determinations and other aspects of this FRN. The EPA also presents updates on additional contaminants from CCL 5, as well as on some of those that have been considered in previous rounds of regulatory determinations and for which the EPA has not yet made a regulatory determination. The agency is also presenting and requesting comment on the process and analyses used for this round of regulatory determinations (i.e., RD 5), the supporting information, and the rationale used to make these preliminary decisions.","document_number":"2025-00133","html_url":"https://www.federalregister.gov/documents/2025/01/15/2025-00133/announcement-of-preliminary-regulatory-determinations-for-contaminants-on-the-fifth-drinking-water","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-01-15/pdf/2025-00133.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-00133.pdf?1736862322","publication_date":"2025-01-15","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":"Report. \n \n \n CDR \n Chemical Data Reporting. \n \n \n ChE \n Cholinesterase. \n \n \n CRL \n Cancer Risk Level. \n \n \n CSF \n Cancer Slope Factor. \n \n \n CWA \n Clean <span class=\"match\">Water</span> Act. \n \n \n CWS \n Community <span class=\"match\">Water</span> System. \n \n \n CWSS \n Community <span class=\"match\">Water</span> System Survey. \n \n \n DBP \n Disinfection Byproduct. \n \n \n DDE \n 1,1-Dichloro-2,2-bis(p-chlorophenyl)ethylene. \n \n \n DWI \n <span class=\"match\">Drinking</span> <span class=\"match\">Water</span> Intake. \n \n \n DWI-BW \n <span class=\"match\">Drinking</span> <span class=\"match\">Water</span> Intake Adjusted for Body Weight. \n \n \n EF \n Exposure Factor. \n \n \n EPA \n U.
