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) has submitted a request to the Office of Management and Budget (OMB) to extend its information collection regarding the implementation of the 8-hour National Ambient Air Quality Standards for Ozone. This extension is needed to help states manage nonattainment areas for the 2008 and 2015 ozone standards by requiring plans that include solutions for improving air quality. Public comments on this proposal are being accepted until February 18, 2025. The proposal notes a reduction in the annual burden because fewer states now need to comply with the older standards.

The Environmental Protection Agency (EPA) is approving updates to Ohio's State Implementation Plan for nitrogen oxide standards. These updates were submitted by the Ohio Environmental Protection Agency and involve minor changes to rule language and references to make them more current and accurate. The EPA sees these changes as noncontroversial and has decided to issue a direct final rule, which will take effect on February 28, 2025, unless negative feedback is received by January 29, 2025. If adverse comments are received, the rule will be withdrawn and addressed in a future proposal.

The Environmental Protection Agency (EPA) issued a final rule that partially approves and partially disapproves Arizona's State Implementation Plan (SIP) for addressing regional haze, a form of air pollution. Arizona's plan aimed to tackle haze by revising strategies to improve visibility in protected natural areas. The EPA found that while some parts of the plan meet federal requirements, others do not because they lack adequate analysis or justification. The EPA's decision starts a process that could lead to federal intervention unless Arizona submits an improved plan that meets all necessary criteria.

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 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.

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) 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 updates to New Jersey's State Implementation Plan (SIP) regarding regulations for minor source facilities and major source facilities without an operating permit. These revisions aim to ensure that the National Ambient Air Quality Standards are met and improve air quality in New Jersey by aligning federal and state regulations. The approval includes most of New Jersey's submitted rule revisions but excludes certain odor and affirmative defense provisions. The rule takes effect on March 31, 2025, following a period where no public comments were received on the proposed changes.
