April 14, 2015 – Federal Register Recent Federal Regulation Documents

This action proposes special conditions for the Honda Aircraft Company, Model HA-420 airplane. This airplane will have a novel or unusual design feature associated with the installation of lithium-ion (Li-ion) batteries. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The Alcohol and Tobacco Tax and Trade Bureau (TTB) proposes to establish the approximately 306,650-acre ``Lewis-Clark Valley'' viticultural area in portions of Nez Perce, Lewis, Clearwater and Latah Counties in Idaho and Asotin, Garfield, and Whitman Counties in Washington. TTB also proposes to modify the boundary of the existing Columbia Valley viticultural area to eliminate a potential overlap with the proposed Lewis-Clark Valley viticultural area. The proposed boundary modifications would decrease the size of the approximately 11,370,320-acre Columbia Valley viticultural area by approximately 57,020 acres. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase. TTB invites comments on these proposals.

The Alcohol and Tobacco Tax and Trade Bureau (TTB) proposes to establish the approximately 29,369-acre ``Lamorinda'' viticultural area in Contra Costa County, California. The proposed viticultural area lies entirely within the larger San Francisco Bay viticultural area and the multicounty Central Coast viticultural area. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase. TTB invites comments on this proposed addition to its regulations.

The Coast Guard has issued a temporary deviation from the operating schedule that governs the U.S. Highway 90 swing highway bridge across the Chef Menteur Pass, mile 2.8, at Lake Catherine, Orleans Parish, Louisiana. The deviation is necessary to ensure the safety of participants in the Ochsner Ironman 70.3 New Orleans event as they travel across the bridge as part of the bike and run courses. This deviation allows the bridge to remain in the closed-to-navigation position continuously during the event.

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Ventura County Air Pollution Control District (VCAPCD) and Eastern Kern Air Pollution Control District (EKAPCD) portions of the California State Implementation Plan (SIP). These revisions clarify, update, and revise exemptions from New Source Review (NSR) permitting requirements, for various air pollution sources.

We are superseding Airworthiness Directive (AD) 2015-02-04 for certain Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2015- 02-04 required installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. This new AD continues to require installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. This AD was prompted by our determination that the published version of AD 2015-02-04 incorrectly identified the AD number as ``AD 2014-02-04'' in a certain paragraph. We are issuing this AD to prevent chafing of the electrical wiring, which could result in a short circuit and generation of smoke in the cockpit, potential loss of several functions essential for safe flight, and consequent reduced controllability of the airplane.

The Postal Service proposes to replace USPS STD 7B, which governs the design of curbside mailboxes, with new USPS STD 7C. The proposed new STD 7C was developed internally to meet the operational requirements of the Postal Service.

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the public comment period on the January 25, 2013, proposed designation of critical habitat for the Zuni bluehead sucker (Catostomus discobolus yarrowi) under the Endangered Species Act of 1973, as amended (Act). We also announce the availability of the draft economic analysis, draft environmental assessment, and amended required determinations of the proposed designation. In addition, we are proposing revisions to the proposed critical habitat boundaries that would decrease our total proposed critical habitat designation for the Zuni bluehead sucker from approximately 475.3 kilometers (291.3 miles) to approximately 228.4 kilometers (141.9 miles). We are reopening the comment period to allow all interested parties an opportunity to comment simultaneously on the revisions to the proposed critical habitat designation described in this document, the associated draft economic analysis and draft environmental assessment, and the amended required determinations section. Comments previously submitted need not be resubmitted, as they will be fully considered in preparation of the final rule.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300ER, and 777F series airplanes. This AD was prompted by a report of a jettison fuel pump that was shut off by the automatic shutoff system during the center tank fuel scavenge process on a short-range flight and a subsequent failure analysis of the fuel scavenge system. This AD requires making wiring changes, modifying certain power panels, installing electrical load management system 2 (ELMS2) software, and accomplishing a functional test. We are issuing this AD to prevent extended dry running of the jettison fuel pumps, which can be a potential ignition source inside the main fuel tanks, and consequent fuel tank fire or explosion in the event that the jettison pump overheats or has an electrical fault.

As required by the Energy Policy and Conservation Act of 1975 (EPCA), as amended, the U.S. Department of Energy (DOE) proposes to establish a mathematical conversion factor for the purpose of translating efficiency ratings for water heaters under the test method currently in effect to the ratings under the amended test method promulgated by DOE in a final rule published on July 11, 2014 (hereinafter referred to as the ``the July 2014 final rule''). Compliance with the amended test procedure is required beginning on the later of: one year after the publication of a final rule that establishes a mathematical conversion factor, or December 31, 2015. This rulemaking document proposes a mathematical conversion factor which may be used to convert the existing efficiency ratings under the current Federal test procedure to efficiency ratings under the test procedure adopted in the July 2014 final rule for water heater basic models manufactured, tested and certified prior to the compliance date of the amended test procedure. The amended test procedure applies to all covered consumer water heaters and the covered commercial water heating equipment with residential applications defined in the July 2014 final rule as a ``residential-duty commercial water heater.'' In addition, this document proposes amendments to the minimum energy conservation standards for consumer water heaters and residential-duty commercial water heaters to account for the impact of the new metric, but does not alter the stringency of the existing energy conservation standards. While DOE has not planned a public meeting to discuss this proposal, DOE is willing to consider a request to hold a meeting.

We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 series airplanes, and Model Avro 146-RJ series airplanes. This AD was prompted by a report of a pressurization problem on an airplane during climb-out; a subsequent investigation showed a crack in the fuselage skin. This AD requires require repetitive external eddy current inspections on the aft skin lap joints of the rear fuselage for cracking, corrosion, and other defects, and repair if necessary. We are issuing this AD to detect and correct cracking, corrosion, and other defects, which could affect the structural integrity of the airplane.
