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.

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) has made available a collection of applicability determinations, alternative monitoring decisions, and regulatory interpretations related to various air quality standards and programs, such as NSPS, NESHAP, and others. These determinations help clarify whether specific facilities or equipment must follow certain EPA regulations, and they often involve evaluating requests for alternative monitoring methods or exemptions. A summary of 59 documents added to the Applicability Determination Index on October 22, 2020, includes topics like monitoring plans for emissions from industrial processes and compliance with air quality standards for specific facilities. These documents are available online for public access, and complete details can be found through the EPA's Clean Air Act Compliance Monitoring website.

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 document discusses the Environmental Protection Agency’s (EPA) response to certain comments about the Good Neighbor Plan, which aims to address air pollution impacting downwind states. The EPA explains why each state's obligations under this plan are separate and can function independently even if other states are not participating. The agency clarifies its approach, emphasizing that the plan sets uniform pollution control standards across states to ensure each contributing state reduces emissions effectively, without depending on the involvement of other states. This ensures the plan remains effective and fair, providing consistent pollution reduction regardless of how many states are involved.

The U.S. Environmental Protection Agency (EPA) is seeking nominations for scientific experts to join the Clean Air Scientific Advisory Committee (CASAC). This committee provides independent advice on air quality standards. The EPA is looking for candidates with expertise in fields such as air quality, environmental engineering, and toxicology. Nominations must be submitted by June 2, 2025, and those selected will serve as Special Government Employees for terms of two to three years.

The Environmental Protection Agency (EPA) is proposing to approve revisions submitted by California concerning its State Implementation Plan (SIP), which includes regulations for reducing emissions from new vehicles and engines. The updates encompass several rules on vehicle emissions, such as transitioning to more zero-emission trucks and shuttles, extending warranties for heavy-duty diesel engines, and setting up testing standards for zero-emission powertrains. These regulations are designed to help California meet federal air quality standards and reduce air pollution from vehicles. Comments on this proposal are open until January 21, 2025.

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) is approving revisions to Connecticut's State Implementation Plan (SIP) concerning air quality standards. These updates confirm that Connecticut's plans meet federal requirements for controlling air pollution, specifically for reducing ozone levels in certain areas. The revisions involve checking new source review permits and ensuring accurate emission reporting from sources of pollution like nitrogen oxides and volatile organic compounds. The changes will take effect on May 22, 2025, and ensure compliance with the Clean Air Act.

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.
