✈️Proposed FAA AD Impacts Costs for GE Engine Compliance
The FAA is revising a notice of proposed rulemaking (NPRM) that applied to all General Electric Company (GE) Model CF34-10E2A1, CF34-10E6, CF34-10E6A1, CF34-10E7, and CF34-10E7-B engines with certain part-numbered high-pressure turbine (HPT) shroud/low pressure turbine (LPT) nozzle assemblies installed. This action revises the NPRM by adding Model CF34-10E5 and CF34-10E5A1 engines to the applicability. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM the agency is requesting comments on this SNPRM.

This action revokes the Class D and Class E airspace in the Republic of the Marshall Islands (RMI). RMI is an independent nation, and the FAA does not have regulatory authority to establish or amend domestic airspace pursuant to Title 14 Code of Federal Regulations (14 CFR) part 71 over RMI's land or territorial waters.

This action amends Class E airspace extending upward from 700 feet above the surface for Kenansville, NC, by adding airspace for ECU Health Duplin Heliport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.

This action proposes to revoke Jet Route J-606 and establish United States Area Navigation Route (RNAV) Q-182 in Alaska. The FAA is proposing this action due to the pending decommissioning of the Chinook, AK, Nondirectional Radio Beacon (NDB).
Learn More✈️FAA Proposes New Airworthiness Directive Affecting Airbus Aircraft
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A319-111, -112, -113, -114, -115, -131, - 132, -133 airplanes. This proposed AD was prompted by a widespread fatigue damage (WFD) scenario review for a certification project that indicated several cracks found around the potable water and wastewater service panels were WFD instead of typical fatigue. This proposed AD would require modification of the potable water and wastewater service panels, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Modification of Airspace at Bozeman Yellowstone Airport
This action proposes to modify the Class D surface area airspace, Class E airspace area designated as surface area, Class E airspace areas designated as an extension to a Class D or Class E surface area, and the Class E airspace area extending upward from 700 feet above the surface of the earth at Bozeman Yellowstone International Airport, Bozeman, MT. These actions would support the safety and management of visual flight rules (VFR) and instrument flight rules (IFR) operations at the airport.
Learn More🌎Proposed EPA Regulations on Ethylene Oxide Emissions Standards
The Environmental Protection Agency (EPA) is proposing to establish a new area source category to address chemical manufacturing process units (CMPUs) using ethylene oxide (EtO). The EPA is proposing to list EtO in table 1 to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Chemical Manufacturing Area Sources (referred to as the CMAS NESHAP in this document) and to add EtO- specific requirements to the CMAS NESHAP. The EPA is also proposing to add a fenceline monitoring program for EtO. In addition, the EPA is proposing new requirements for pressure vessels and pressure relief devices (PRDs). This proposal also presents the results of the EPA's technology review of the CMAS NESHAP as required under the Clean Air Act (CAA). As part of this technology review, the EPA is proposing to add new leak detection and repair (LDAR) requirements to the CMAS NESHAP for equipment leaks in organic HAP service and heat exchange systems. The EPA is also proposing performance testing once every 5 years and to add provisions for electronic reporting. We estimate that the proposed amendments to the CMAS NESHAP, excluding the proposed EtO emission standards, would reduce hazardous air pollutant (HAP) emissions from emission sources by approximately 158 tons per year (tpy). Additionally, the proposed EtO emission standards are expected to reduce EtO emissions by approximately 4.6 tpy.

The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove changes to South Carolina's State Implementation Plan (SIP) to revise regulations prescribing minor source permit program requirements, including minor new source review (NSR) requirements as submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (SC DHEC), on the following dates: October 1, 2007; July 18, 2011; June 17, 2013; August 8, 2014; January 20, 2016; July 27, 2016; and April 24, 2020. This action is being proposed pursuant to the Clean Air Act (CAA or Act).

The Environmental Protection Agency (EPA) is taking final action to approve elements of a state implementation plan (SIP) submittal from the State of California to meet Clean Air Act (CAA) "Extreme" nonattainment area requirements for the 1997 8-hour ozone national ambient air quality standards (NAAQS) in the Riverside Co. (Coachella Valley), CA nonattainment area ("Coachella Valley"). We are specifically approving the reasonable further progress (RFP) demonstration and the vehicle miles traveled demonstration.

The Environmental Protection Agency (EPA) is taking final action to correct a November 19, 2020, rulemaking removing the Air Nuisance Rule (ANR) from the Ohio State Implementation Plan (SIP). This action is in response to a February 10, 2023, decision by the United States Court of Appeals for the Sixth Circuit (Sixth Circuit or Court) to remand without vacatur EPA's removal of the ANR from the Ohio SIP. Because the Court did not vacate EPA's removal of the ANR, the ANR is currently not in Ohio's SIP. After reevaluating EPA's November 19, 2020, rulemaking, upon remand, EPA proposed to determine that its November 2020 final action was in error, and to correct that action by reinstating the ANR as part of the Ohio SIP. EPA proposed to take this action on February 22, 2024 and received both supportive and adverse comments. EPA is finalizing this action as proposed, and upon the effective date of this action, the ANR will be reinstated into the Ohio SIP.
