🌫️Proposed Amendments to Connecticut's Air Pollution Regulations by EPA
The Environmental Protection Agency (EPA) is proposing to approve regulatory amendments that revise two previous program approvals from the Connecticut Department of Energy and Environmental Protection (CT DEEP). The revisions include amendments to the Regulations of Connecticut State Agencies (RCSA) that revise the Connecticut State Operating Permit Program and amendments to RCSA that revise limitations on potential to emit Clean Air Act (CAA) pollutants. A significant aspect of this action involves revising the definition of "hazardous air pollutant" in the RCSA in response to EPA adding 1- bromopropane to the list of hazardous air pollutants. This action is being taken under the Clean Air Act.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving the portion of the State Implementation Plan (SIP) submittal from the State of Texas demonstrating that the State satisfies the interstate transport requirements of section 110(a)(2)(D)(i)(I), also known as the "good neighbor" provision of the CAA, for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary National Ambient Air Quality Standard (NAAQS). The good neighbor provision requires each State's implementation plan to contain adequate provisions prohibiting the interstate transport of air pollution in amounts that will contribute significantly to nonattainment, or interfere with maintenance, of a NAAQS in any other State.

Learn More✈️Airworthiness Directive for Airbus SAS
The FAA is superseding Airworthiness Directive (AD) 2017-14- 14, which applied to all Airbus SAS Model A321-111, -112, -131, -211, - 212, -213, -231, and -232 airplanes. AD 2017-14-14 required repetitive inspections for cracking in the cabin floor beam junction at certain fuselage frame locations and repair if necessary. Since the FAA issued AD 2017-14-14, further analysis determined that the compliance times for the inspections must also be based on flight hours. This AD continues to require the actions in AD 2017-14-14, revises compliance times, and adds a provision for optional modifications. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A318-111, -112, -121, and -122 airplanes; A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and - 171N airplanes; A320-211, -212, -214, -216, -231, -232, -233, -251N, - 252N, -253N, -271N, -272N, and -273N airplanes; and A321-111, -112, - 131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -253NY, -271NX, and -272NX airplanes. This AD was prompted by a determination that new airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️FAA Issues New Airworthiness Directive for ATR Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72-212A airplanes. This AD was prompted by a finding that dispatch with a failed main hydraulic pump under the provisions of a certain master minimum equipment list (MMEL) item, combined with failure of the DC EMER BUS, could lead to failure of multiple system losses. This AD requires revising the existing minimum equipment list (MEL) to incorporate new provisions to ensure appropriate actions are taken when the airplane is dispatched with one inoperative main hydraulic pump. The FAA is issuing this AD to address the unsafe condition on these products.
