The Environmental Protection Agency (EPA) is proposing amendments to the New Source Performance Standards and Emission Guidelines for Existing Sources for the Crude Oil and Natural Gas Source Category in response to petitions for reconsideration. Specifically, this action proposes discrete technical changes to two different aspects of the rules. First, this action proposes discrete technical changes to the temporary flaring provisions for associated gas in certain situations. Second, this action proposes discrete technical changes to the vent gas net heating value (NHV) continuous monitoring requirements and alternative performance test (sampling demonstration) option for flares and enclosed combustion devices. In a letter dated May 6, 2024, the EPA notified petitioners and the public that the Agency granted reconsideration on these two aspects of the March 8, 2024 (89 FR 16820) final rule. These amendments neither propose changes to any other aspect of the final rule, nor propose to alter the substance of any emission standards within the final rule. Also, in this action, the EPA proposes to make formatting changes to the regulatory text to meet the required formatting standards of the Office of the Federal Register.

The Safe Drinking Water Act (SDWA), as amended in 1996, requires that the U.S. Environmental Protection Agency (EPA) determine whether to regulate at least five unregulated contaminants every five years. 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.

Learn More⚖️EPA Proposes Regulation for C.I. Pigment
The Environmental Protection Agency (EPA or Agency) is proposing to address the unreasonable risk of injury to human health presented by C.I. Pigment Violet 29 (CASRN 81-33-4, also known as PV29), under its conditions of use as documented in EPA's January 2021 Risk Evaluation for PV29 and the September 2022 Revised Risk Determination for PV29 prepared under TSCA. TSCA requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. To address the identified unreasonable risk, EPA is proposing requirements to protect workers from the unreasonable risk of PV29 during manufacturing and processing, certain industrial and commercial uses of the chemical, and disposal, while also allowing for a reasonable transition period prior to enforcement of said requirements.

Learn More💧Federal Water Quality Standards Withdrawal
The Environmental Protection Agency (the EPA or agency) is withdrawing the proposed rule entitled "Federal Baseline Water Quality Standards for Indian Reservations," which published in the Federal Register on May 5, 2023. The EPA is electing to withdraw and not finalize the proposed rule at this time. Instead, the EPA intends to focus the agency's resources on engaging with Tribes to support Tribes' efforts to seek authority to administer their own water quality standards (WQS) program under the Clean Water Act's provision for eligible Tribes to be treated in a similar manner as states (TAS). The EPA will continue to work closely with, and offer support to, Tribes that are interested in pursuing TAS to administer a WQS program and developing their own WQS under the Clean Water Act.

The Environmental Protection Agency (EPA) is finalizing a limited approval and limited disapproval of revisions to the Maricopa County Air Quality Department (MCAQD or "County") portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from loading of organic liquids and gasoline. Under the authority of the Clean Air Act (CAA or "Act"), this action simultaneously approves local rules that regulate these emission sources and directs Arizona to correct rule deficiencies. We are also finalizing a disapproval of MCAQD's reasonably available control technology (RACT) demonstration for the source categories associated with these rules for the 2008 8-hour ozone national ambient air quality standard (NAAQS) in the Phoenix-Mesa ozone nonattainment area.
