The Environmental Protection Agency (EPA) has proposed a new rule regarding California's Regional Haze State Implementation Plan (SIP) for the second implementation period. The EPA plans to partially approve and partially disapprove the SIP submitted by California. While the plan addresses some standards, such as monitoring and emission inventories, it falls short in areas like setting proper long-term strategies and progress goals related to visibility improvement. This proposed rule opens a discussion about the elements of the SIP that meet federal requirements and those that need further improvement.

The Environmental Protection Agency (EPA) proposed a rule to approve part of Louisiana's State Implementation Plan (SIP) for meeting air quality standards related to sulfur dioxide (SO₂), following the Clean Air Act guidelines. The plan addresses interstate air pollution transport, ensuring emissions from Louisiana do not significantly harm air quality in neighboring states. The EPA's review found no significant contribution to air pollution issues in nearby states and supports the proposal to approve Louisiana's SIP. Public comments on this proposal are invited until May 9, 2025.

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 approved a request from the Indiana Department of Environmental Management (IDEM) to update the Indiana State Implementation Plan (SIP) by revising the reference to the Code of Federal Regulations (CFR) from the 2018 edition to the 2022 edition. This change is meant to keep Indiana's regulations in sync with the current federal standards. The decision, effective January 27, 2025, received no negative feedback during the public comment period. The rule does not impose additional requirements and is consistent with existing federal regulations.

The Environmental Protection Agency (EPA) is proposing to approve revisions to Pennsylvania's state implementation plan (SIP) to implement reasonably available control technology (RACT) for major sources of nitrogen oxides (NOX) and volatile organic compounds (VOC). These changes are aimed at reducing ozone pollution under the 1997 and 2008 national air quality standards. Pennsylvania submitted these revisions to establish RACT for eight specific sources out of the nine initially proposed. This proposal is part of efforts to ensure cleaner air and better public health by meeting federal Clean Air Act requirements.

The Environmental Protection Agency (EPA) is finalizing a rule regarding air quality standards in Arizona's Maricopa County. The rule involves a mix of limited approval and disapproval concerning revisions to rules about emissions of volatile organic compounds (VOCs) from loading organic liquids and gasoline. Though some rules improve the state's plan and meet the Clean Air Act standards, others are deficient, requiring Arizona to make corrections. If not corrected within two years, federal sanctions may be imposed.

The Environmental Protection Agency (EPA) is proposing to approve a revision to New York's State Implementation Plan (SIP) to reduce nitrogen oxide (NOx) emissions from certain combustion turbines during the ozone season. The revision includes stricter emission limits aimed at improving air quality and meeting federal ozone standards. New York's approach involves phasing in the new limits and offers flexibility to turbine operators through two compliance options. This proposal is part of ongoing efforts to clear harmful pollutants and protect public health by ensuring states adhere to the Clean Air Act.

The Environmental Protection Agency (EPA) is proposing to approve a revision to New York's plan for municipal solid waste landfills. This plan aims to reduce emissions of harmful gases like non-methane organic compounds and methane by lowering the emission threshold that requires landfills to install gas collection and control systems. The EPA believes the revised plan meets federal guidelines and will improve air quality by making the New York regulations enforceable at the federal level. Comments on this proposal must be submitted by March 29, 2021.

The Environmental Protection Agency (EPA) is finalizing a rule concerning air quality in Maricopa County, Arizona. The rule partially approves, partially disapproves, and partially conditionally approves revisions to the air quality plan for the area, focusing on controlling emissions to meet 2008 ozone standards. The EPA is conditionally approving certain rules for controlling emissions from surface coating operations, while requiring updates for others within a year, or they will face disapproval. No comments were received during the public comment period, and failure to meet these conditions might result in federal sanctions.

The Environmental Protection Agency (EPA) has approved a plan from Pennsylvania to maintain air quality standards for ozone in the Johnstown area. This plan is part of the state's efforts to meet the 1997 8-hour ozone national ambient air quality standard. The approval makes certain commitments federally enforceable as part of Pennsylvania's Implementation Plan. The plan focuses on ongoing air quality monitoring and measures to ensure that the area continues to meet required standards.
