🌫️EPA Proposes Ozone Standards Failure for San Joaquin Valley
The Environmental Protection Agency (EPA) is proposing to determine that the San Joaquin Valley, California area failed to attain the 1997 8-hour ozone national ambient air quality standard by its June 15, 2024 "Extreme" area attainment date. This proposed determination is based on quality-assured and certified ambient air quality monitoring data from 2021 through 2023.
Learn More🌬️Mojave Desert Air Quality Regulation and Its Business Implications
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Mojave Desert Air Quality Management District (MDAQMD or "the District") portion of the California State Implementation Plan (SIP). These revisions concern definitions that are necessary to implement and enforce local rules that regulate air pollution. We are proposing to approve a definitions rule under the Clean Air Act (CAA or the "Act"). We are also proposing to approve the rescission of earlier versions of this rule from the California SIP as they are no longer needed to under the CAA. We are taking comments on this proposal and plan to follow with a final action.
Learn More✈️FAA Airworthiness Directive for Airbus A350
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report of loss of control of an outboard aileron surface due to hydraulic fluid contaminating an electronic card of the flight control remote module (FCRM). This AD requires replacing any affected elevator FCRM and prohibits installing aileron or spoiler FCRMs in place of elevator or rudder FCRMs. This AD also limits the installation of FCRMs under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🛩️New Airworthiness Directive for DG Aviation GmbH Gliders
The FAA is adopting a new airworthiness directive (AD) for all DG Aviation GmbH (type certificate previously held by DG Flugzeugbau GmbH) Model DG-1000T gliders. This AD was prompted by reports of propeller separation. This AD requires revising the glider flight manual and installing "Motor INOP" placards to prohibit operation with the powerplant. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More🏠Restore Dust-Lead Hazard Standards
The Environmental Protection Agency (EPA or the Agency) is correcting a final rule that appeared in the Federal Register of November 12, 2024, that finalized several revisions to EPA's lead-based paint (LBP) regulations. Subsequent to publication, the Office of the Federal Register (OFR) informed the Agency that there were errors in the amendatory instructions that describe specific revisions for two sections of the regulation. In the Federal Register of December 16, 2024, EPA published a technical correction to the final rule that explained the errors and the corresponding technical corrections that the Agency believed would address the errors identified by the OFR. Unfortunately, that technical correction did not fix the amendatory instructions prior to the effective date of the final rule. As a result, when the final rule became effective on January 13, 2025, three subparagraphs of regulatory text were inadvertently deleted--a change to the post-abatement regulatory activities that EPA did not intend to make. This action corrects that error by restoring the inadvertently deleted text in the regulations.

Learn More✈️Proposed Airworthiness Directive for Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2024-25-06, which applies to all Airbus SAS Model A318-series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, - 151N, -153N, and -171N airplanes; Model A320-series airplanes; and Model A321-series airplanes. AD 2024-25-06 requires repetitive inspection of the main landing gear (MLG) doors, and, depending on findings, accomplishment of applicable corrective actions, and prohibits the installation of affected parts. The FAA has determined that replacing the MLG door is necessary to address the unsafe condition. This proposed AD would continue to require the actions in AD 2024-25-06 and would require replacing affected parts with serviceable parts. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More🌫️Ohio's Regional Haze Plan
The Environmental Protection Agency (EPA) is approving the Regional Haze State Implementation Plan (SIP) revision submitted by the Ohio Environmental Protection Agency (Ohio or Ohio EPA) on July 30, 2021, as supplemented on August 6, 2024, and clarified by Ohio on June 16, 2025, as satisfying applicable requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule for the program's second implementation period. Together, Ohio's 2021 SIP submission, 2024 SIP supplement, and 2025 clarification address the requirement that States must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. Ohio's complete SIP submission also addresses other applicable requirements for the second implementation period of the Regional Haze Program. EPA is taking this action pursuant to sections 110 and 169A of the CAA.

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company (Boeing) Model 737-600, -700, -700C, -800, - 900, and -900ER series airplanes. This proposed AD was prompted by a report of improper grinding of the inner diameter of the main landing gear (MLG) outer cylinders, resulting in possible heat damage to the outer cylinders. This proposed AD would require a records check or inspection to determine if an affected outer cylinder is installed and replacing all affected outer cylinders. The FAA is proposing this AD to address the unsafe condition on these products.
