The Environmental Protection Agency (EPA) has finalized a Federal Implementation Plan (FIP) under the Clean Air Act for the Mojave Desert Air Quality Management District in California. This new rule includes stricter guidelines for New Source Review (NSR) in nonattainment areas where air quality standards are not met. The FIP aims to regulate the construction of new major sources and modifications of existing sources, addressing deficiencies in the existing Mojave Desert program. An important aspect of this rule is the EPA's disapproval of a Mojave Desert District rule regarding emissions offsets, following a court decision questioning the EPA's previous approval of that rule.

The Environmental Protection Agency (EPA) is proposing to approve a Tribal Implementation Plan (TIP) submitted by the Northern Cheyenne Tribe. The TIP aims to regulate air pollution on the Tribe's Indian Reservation and tribal trust parcels by maintaining national air quality standards through an open burning program. The plan includes standards for pollutants like sulfur dioxide, particulate matter, and ozone, along with enforcement protocols. The EPA's approval would make these regulations federally enforceable, aligning with the Clean Air Act.

The Environmental Protection Agency (EPA) is making available Volumes 1 and 2 of the Integrated Review Plan (IRP) for the National Ambient Air Quality Standards (NAAQS) for Ozone and Related Photochemical Oxidants. These volumes provide background information, policy-relevant issues, and key considerations for the review of air quality criteria concerning ozone. The public can comment on Volume 2 until January 21, 2025, and these comments will help inform the EPA's further development and public consultation. This work is part of a broader effort to ensure air quality standards protect public health and welfare under the Clean Air Act.

The Environmental Protection Agency (EPA) is proposing to approve a revision to Connecticut's State Implementation Plan (SIP). This update introduces state regulations designed to limit emissions from major stationary sources, helping them stay below specific environmental thresholds. By adhering to these limits, eligible sources could avoid having to meet certain strict requirements usually imposed on larger pollution sources. The proposed rule is being evaluated to ensure it aligns with the Clean Air Act, and public comments are invited before a final decision is made.

The Environmental Protection Agency (EPA) is proposing to approve a revision to New York's State Implementation Plan (SIP) for ozone air quality standards, specifically for the Lehigh Cement Company in Glens Falls, New York. This revision involves implementing controls for nitrogen oxide (NOX) emissions from a cement kiln, requiring them to use Reasonably Available Control Technology (RACT). The proposed regulations are part of efforts to meet ozone standards and follow a nationwide consent decree. The EPA determined that this plan would not interfere with National Ambient Air Quality Standards (NAAQS) or other requirements of the Clean Air Act.

The Environmental Protection Agency (EPA) is proposing to approve revisions to West Virginia's state implementation plan (SIP), which updates the state's incorporation of the EPA's National Ambient Air Quality Standards (NAAQS) and related monitoring methods. These changes span updates made between June 2018 and June 2019, including new reference methods for measuring air pollutants like sulfur oxides, ozone, nitrogen dioxide, and carbon monoxide. This proposal is made under the Clean Air Act, and the EPA is inviting public comment on this update, although they are not seeking input on the specific levels of NAAQS already established in prior proposals.

The Environmental Protection Agency (EPA) has approved a change to the State Implementation Plan (SIP) submitted by Kentucky, which updates the status designations of areas within the state to align with federal standards for air quality. This update affects several National Ambient Air Quality Standards (NAAQS) and ensures that Kentucky's regulations are in line with the Clean Air Act. The changes impact designations for pollutants like ozone, particulate matter, and sulfur dioxide, confirming how these areas meet or do not meet federal air quality standards. The effective date of this rule is March 31, 2021.

The Environmental Protection Agency (EPA) issued a correction for a previously published rule regarding air quality standards for particulate matter, particularly focusing on PM2.5 standards. The final rule, originally published in March 2024, had errors in its text about deadlines for state plans and technical descriptions for air quality monitors. The EPA clarified that states must submit implementation plans within three years of the standards' announcement, not their effective date. Additionally, several technical corrections were made, such as updating measurement methods and fixing typographical errors, all of which don't change the rule's substance.

The Environmental Protection Agency (EPA) is proposing to approve New Jersey's revisions to their State Implementation Plan (SIP) related to air quality permits and certificates for minor and major facilities without operating permits. The goal is to ensure that these revised regulations meet the National Ambient Air Quality Standards (NAAQS) and are in line with the existing state regulations. The proposed changes involve several areas, such as altering the applicability of permits, defining new sources, and establishing conditions for permits and certificates. The EPA is currently seeking public comments on these proposed revisions until January 16, 2025.
