May 12, 2015 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes, and Model ATR72-102, -202, -212, and -212A airplanes. This proposed AD was prompted by a report of chafed wires between electrical harnesses. This proposed AD would require inspections for wiring discrepancies, and corrective actions if necessary. We are proposing this AD to detect and correct damaged wiring and incorrect installation of the wiring harness and adjacent air ducts, which could lead to wire harness chafing and arcing, possibly resulting in an on-board fire.

The Environmental Protection Agency (EPA) is partially approving and partially disapproving the State Implementation Plan (SIP) submittal from Washington demonstrating that the SIP meets the infrastructure requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for fine particulate matter (PM2.5) on July 18, 1997, October 17, 2006, and December 14, 2012 (collectively, the PM2.5 NAAQS). The CAA requires that each state, after a new or revised NAAQS is promulgated, review its SIP to ensure that it meets the infrastructure requirements necessary to implement the new or revised NAAQS. On September 22, 2014, Washington made a SIP submission to establish that the Washington SIP meets the infrastructure requirements of the CAA for the PM2.5 NAAQS, except for certain elements related to the Prevention of Significant Deterioration (PSD) permitting program currently addressed under a Federal Implementation Plan (FIP), certain elements of the regional haze program currently addressed under a FIP, and specific requirements related to interstate transport which the State will address in a separate submittal. The EPA has determined that Washington's SIP is adequate for purposes of the infrastructure SIP requirements of the CAA for the PM2.5 NAAQS, with the exceptions noted above. The SIP deficiencies related to PSD permitting and regional haze, however, have already been adequately addressed by the existing EPA FIPs and, therefore, no further action is required by Washington or the EPA for those elements. The EPA will address the remaining interstate transport requirements in a separate action.

Environmental Protection Agency (EPA) is proposing to approve a May 11, 2012 State Implementation Plan (SIP) submission from the State of Colorado that is intended to demonstrate that its SIP meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2006 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS). This submission addresses the requirement that Colorado's SIP contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. EPA is proposing to determine that Colorado's existing SIP contains adequate provisions to ensure that air emissions in Colorado do not significantly contribute to nonattainment or interfere with maintenance of the 2006 24-hour PM2.5 NAAQS in any other state, or interfere with another state's measures to prevent significant deterioration (PSD) of air quality or to protect visibility. EPA is also proposing to approve the portion of Colorado's submission that addresses the CAA requirement that SIPs contain adequate provisions related to interstate and international pollution abatement.

Pursuant to Section 189a. (2) of the Atomic Energy Act of 1954, as amended (the Act), the U.S. Nuclear Regulatory Commission (NRC) is publishing this regular biweekly notice. The Act requires the Commission to publish notice of any amendments issued, or proposed to be issued and grants the Commission the authority to issue and make immediately effective any amendment to an operating license or combined license, as applicable, upon a determination by the Commission that such amendment involves no significant hazards consideration, notwithstanding the pendency before the Commission of a request for a hearing from any person. This biweekly notice includes all notices of amendments issued, or proposed to be issued, from April 16, 2015, to April 29, 2015. The last biweekly notice was published on April 28, 2015.

The NCUA Board (Board) proposes to exclude Central Liquidity Facility (CLF)-related bridge loans (CLF-related bridge loans) from the aggregate unsecured lending cap to one borrower applicable to a corporate credit union (Corporate). Specifically, a CLF-related bridge loan that is exempt from that cap is a bridge loan made by a Corporate to a natural person credit union when the natural person credit union has been approved for a loan by the CLF and is awaiting funding from the CLF. Additionally, the proposal excludes CLF-related bridge loans from the calculation of ``net assets'' and ``net risk weighted assets'' for determining minimum capital requirements. This proposal results largely from comments the Board received on the November 2014 proposed rule amending NCUA's Corporate regulations.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-601, B4-603, and B4-605R airplanes; Model A300 F4- 605R airplanes; Model A300 C4-605R Variant F airplanes; and Model A310- 204 and -304 airplanes; powered by General Electric (GE) Model CF6-80C2 series engines. This AD was prompted by reports of two single-engine flameout events during inclement weather. This AD requires installing a shunt of the rotary selector (introducing an auto-relight function); and, for certain airplanes, a wiring modification to a certain circuit breaker panel. We are issuing this AD to prevent a long engine restart sequence after a non-selection of continuous relight by the crew and a flameout event of both engines, which could result in reduced controllability of the airplane, especially at low altitude.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-400F series airplanes. This AD was prompted by reports of cracking in the main equipment center (MEC) drip shield and exhaust plenum. This AD requires installing a fiberglass reinforcing overcoat on the MEC drip shield. We are issuing this AD to prevent water penetration into the MEC, which could result in an electrical short and potential loss of several functions essential for safe flight.
