The Environmental Protection Agency (EPA) announced its decision to grant California a waiver from the Clean Air Act preemption. This waiver allows the California Air Resources Board's (CARB's) Advanced Clean Cars II (ACC II) regulations to set new emission standards for vehicles, which are stricter than federal requirements and apply to 2026 and later model years. The EPA determined that California's standards are necessary for public health and are not arbitrary or unreasonable. The decision ensures that California can enforce rules aimed at reducing emissions, including requirements for zero-emission vehicles.

The Environmental Protection Agency (EPA) is announcing that they have temporarily decided not to enforce penalties against the San Joaquin Valley Unified Air Pollution Control District in California. This decision comes after the California Air Resources Board submitted a plan aiming to fix issues in the district's air pollution permit program. Although initial problems led to the EPA disapproving a district rule in 2023, the current plan addresses most issues, prompting the EPA to delay penalties while considering the public's comments. The EPA is using a special process to make this determination quickly because they believe it's in the public's best interest.

The Environmental Protection Agency (EPA) has approved a revision to the South Coast Air Quality Management District portion of the California State Implementation Plan (SIP) to reduce emissions of oxides of nitrogen (NOX) from on-road heavy-duty vehicles. This measure, named the South Coast Incentive Measure, includes commitments by the California Air Resources Board (CARB) to achieve specified emission reductions, ensure project compliance, and submit annual reports. The plan is enforceable under the Clean Air Act, allowing citizens and the EPA to take action if CARB fails to meet its commitments. The rule will become effective on February 16, 2021.

The Environmental Protection Agency (EPA) has announced its decision to grant California a waiver from federal Clean Air Act preemption for its Heavy-Duty Vehicle and Engine "Omnibus" Low NOx Regulations, allowing California to enforce its own stricter emission standards. This decision also includes an authorization for parts of the regulations concerning off-road diesel engines. The EPA concluded that California's regulations are necessary due to the state's specific air quality needs and that they are at least as protective of public health as federal standards. Petitions to review this decision must be submitted by March 7, 2025.

The Environmental Protection Agency (EPA) has announced its decision to partially grant California's request to amend regulations for diesel-fueled Transport Refrigeration Units (TRUs). These amendments include various requirements, such as using specific refrigerants and transitioning to zero-emission refrigeration units. However, the EPA did not make a decision on the mandate for owners to switch a portion of their diesel truck TRU fleet to zero-emission technology by a specific date. The EPA's decision follows a review of California's standards to ensure they protect public health and comply with federal regulations.

The Environmental Protection Agency (EPA) has partially approved California's request to amend its Commercial Harbor Craft regulations. These changes, introduced in 2022, aim to set new emission standards for various types of harbor craft in California, like pilot boats and fishing vessels. The EPA's decision is based on the Clean Air Act, which allows California to enforce stricter pollution standards than federal ones if justified. Petitions for opposing this decision must be submitted by March 11, 2025.

The Environmental Protection Agency (EPA) has granted the California Air Resources Board (CARB) the authority to make amendments to its regulations for fleets of diesel-fueled, off-road vehicles. These changes, known as the 2022 Off-Road Fleets Amendments, aim to phase out old and high-emitting vehicles and require the use of specific renewable diesel. These regulations will be implemented between 2024 and 2036 to support California's emission reduction goals. The decision was made under the Clean Air Act, which allows California to have stricter standards for nonroad engines as long as they meet certain federal conditions.

The Environmental Protection Agency (EPA) is making an interim decision to delay certain penalties for the Mojave Desert Air Quality Management District (MDAQMD) in California. The delay is because the MDAQMD has updated Rule 1157 to fix issues related to controlling nitrogen oxide emissions. This decision means relief from penalties, initially triggered by EPA's limited disapproval in 2023, may become permanent if the amendments are fully approved following public comments. The EPA is allowing the public to comment on this decision until January 27, 2025.

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.
