August 21, 2014 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of New Hampshire. These revisions contain an updated regulation establishing reasonably available control technology (RACT) for sources of nitrogen oxides (NOX), four updated source-specific orders for either volatile organic compound (VOC) or NOX RACT, and a request to withdraw from the SIP a previously approved NOX RACT order. The intended effect of this action is to approve the updated NOX RACT regulation and updated VOC and NOX RACT orders into the New Hampshire SIP, and to also approve New Hampshire's request to remove one NOX RACT order from the SIP. This action is being taken in accordance with the Clean Air Act.

We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-500 airplanes. This AD was sent previously to all known U.S. owners and operators of these airplanes as an emergency AD. This AD requires an inspection and replacement as necessary of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint. We are issuing this AD to correct the unsafe condition on these products.

GSA is amending the Federal Travel Regulation (FTR) by incorporating recommendations of the Governmentwide Relocation Advisory Board (GRAB) concerning calculation of reimbursements for taxes on relocation expenses. In addition, this final rule alters the process for calculating reimbursements for taxes on extended temporary duty (TDY) benefits to correct errors and to align that process with the final changes to the relocation income tax process.

We are superseding Airworthiness Directive (AD) 2005-15-04 for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. AD 2005-15-04 required operators to assign serial numbers or part numbers to certain landing gear parts; establish the number of landings on the parts, if necessary; and revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to reflect the new life limits of the landing gear parts. This new AD adds airplanes to the applicability, requires operators to assign serial numbers or part numbers to certain additional landing gear parts to establish the number of landings on the parts if necessary, and requires operators to record in all required airplane technical records and manuals the new part numbers, serial numbers, and landings assigned to these parts. This AD was prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.
