The Environmental Protection Agency (EPA) has proposed to approve a State Implementation Plan (SIP) from Louisiana that aims to meet the air quality standards set by the Clean Air Act. Submitted on November 4, 2020, the plan addresses requirements to reduce emissions that affect visibility and pollution in neighboring states, fulfilling a previous shortcoming related to Prong 4, which involves visibility transport rules. With the approval of Louisiana's regional haze plan, the EPA believes the state now satisfies the necessary provisions for various pollutants, including ozone, nitrogen dioxide, sulfur dioxide, and particulate matter (PM2.5). The plan ensures that Louisiana's measures align with federal air quality standards and do not interfere with the air quality efforts of other states.

The Environmental Protection Agency (EPA) has finalized a rule for managing commercial and industrial solid waste incineration units (CISWI) that were built on or before June 4, 2010, and not updated since August 7, 2013. This rule applies to states without approved plans for reducing emissions from these units and entails adopting federal guidelines to decrease pollutants like lead, mercury, and sulfur dioxide. In addition, the rule introduces changes to testing, monitoring, and recording requirements, emphasizing reductions in emissions and the implementation of stricter operational practices to curb pollution. Units in Alaska that qualify as "small, remote incinerators" are exempt from certain standards until further regulations address this category.

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 or conditionally approve a plan by the State of California to address air quality standards for ozone in Western Nevada County, California. This state implementation plan (SIP) includes strategies and measures to meet the federal standards for ozone pollution, focusing on emissions inventories, attainment demonstrations, and reasonable further progress. The EPA is also proposing conditional approval for contingency measures, with the expectation that the state will submit additional rules within one year. The overall goal is to ensure that Western Nevada County meets and maintains national ambient air quality standards for ozone to protect public health.

The Environmental Protection Agency (EPA) is proposing to approve Pennsylvania's state implementation plan to maintain air quality standards for ozone in the York-Adams area. This plan, submitted by the Pennsylvania Department of Environmental Protection, aims to uphold the 1997 standard for ozone until 2028, ensuring the region does not exceed limits set for air pollutants. The plan includes specific actions Pennsylvania will take to monitor and manage ozone levels, as well as steps to quickly address any potential violations. Public comments on this proposal are welcomed before final approval.

The Environmental Protection Agency (EPA) is reopening the public comment period on a proposed rule concerning air quality standards in Fairbanks North Star Borough, Alaska. Originally published on January 8, 2025, the proposed rule pertains to the 2006 24-hour fine particulate matter (PM2.5) standards. Due to requests for more time to evaluate the proposal, the EPA has extended the comment period by 30 days, until April 23, 2025. However, the EPA is not reopening the comment period for the transportation conformity adequacy process related to motor vehicle emissions budgets.

The Bureau of Ocean Energy Management (BOEM) is planning to renew its information collection under the Paperwork Reduction Act, with a focus on pollution prevention and control in offshore oil and gas activities. The agency is seeking public comments on this information collection, which primarily concerns air quality standards compliance and the reporting of emissions. To streamline and improve this process, BOEM is introducing a new system, the OCS Air Quality System (OCS AQS), to replace outdated software. The public has until February 11, 2021, to submit comments, which will help BOEM minimize the reporting burden while ensuring compliance with environmental regulations.

The Environmental Protection Agency (EPA) has approved changes to New York's State Implementation Plan regarding air quality standards. These changes focus on Knowlton Technologies LLC in Watertown, New York. The plan includes setting limits on volatile organic compounds (VOC) emissions from two large methanol storage tanks to help meet ozone air quality standards. This ruling follows federal guidelines and does not introduce new requirements beyond state law.

The Environmental Protection Agency (EPA) has made an interim final decision to delay sanctions against the State of Alaska after it submitted a plan that meets Clean Air Act requirements related to air quality standards for fine particulate matter in Fairbanks North Star Borough. These sanctions were initially triggered due to the past disapproval of Alaska's air quality plan. The EPA's decision relies on a proposed approval of Alaska's revised plan and gives the public the opportunity to comment on this delay of sanctions. This action aims to avoid imposing penalties while the approval process for the revised plan is ongoing. The EPA is not requiring any new changes or imposing burdens as part of this action.

The Environmental Protection Agency (EPA) concluded that the Piti-Cabras area in Guam did not meet the required sulfur dioxide air quality standards by the deadline of April 9, 2023. This decision is based on the analysis of available data, showing emissions were too high, and necessary emission controls were not implemented on time. As a result, Guam must now submit a revised plan to achieve air quality standards within the next five years, according to the Clean Air Act requirements. This measure ensures continued efforts to protect public health from pollution.
