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) 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 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.
