March 21, 2019 – Federal Register Recent Federal Regulation Documents

We are removing AD 2007-22-05 and AD 2013-13-13 (referred to after this as ``the affected ADs''), which applied to Airbus SAS Model A300-600 and A310 series airplanes. The affected ADs required certain actions to address various unsafe conditions. The affected ADs are no longer necessary because we have since issued other ADs to address these unsafe conditions. Accordingly, we are removing the affected ADs.

This proposed rule would establish the Financial Assistance Interior Regulation (FAIR). The FAIR supplements the Office of Management and Budget (OMB) Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards (Uniform Guidance), which was adopted by the Department of the Interior (DOI or Department) on December 19, 2014. This proposed rule would support the Department's goal of improving its financial assistance program, consolidate the Department's financial assistance regulations and policies derived from the OMB Uniform Guidance, and streamline the implementation of OMB's Uniform Guidance and DOI financial assistance policy.

We are superseding Airworthiness Directive (AD) 2017-20-01 for certain Honeywell International Inc. (Honeywell) TFE731-20 and TFE731- 40 turbofan engines. AD 2017-20-01 required removing the affected fan disk and replacing it with a fan disk eligible for installation. Since we issued AD 2017-20-01, we determined that some turbofan engine models were omitted from the applicability of AD 2017-20-01. This AD adds turbofan engine models to the applicability and removes the Honeywell TFE731-20 turbofan engine model from the applicability. This AD requires removal of affected fan disks and replacement with parts eligible for installation. This AD was prompted by two fan disks found with surface rollovers in the dovetail slot area. We are issuing this AD to address the unsafe condition on these products.

This action proposes to amend the Class D airspace and Class E airspace extending upward from 700 feet above the surface at Richard Lloyd Jones Jr. Airport, Tulsa, OK, and the Class E airspace extending upward from 700 feet above the surface at William R. Pogue Municipal Airport, Sand Springs, OK, which is contained within the Tulsa, OK, airspace legal description. The FAA is proposing this action as the result of the decommissioning of the Glenpool VHF omnidirectional range (VOR) navigation aid, which provided navigation information for the instrument procedures at these airports, as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of the Richard Lloyd Jones Jr. Airport would also be updated to coincide with the FAA's aeronautical database.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface in Isbell Field Airport, Fort Payne, AL, to accommodate airspace reconfiguration due to the decommissioning of the Fort Payne non-directional radio beacon and cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also would update the airport name and geographic coordinates of this airport. In addition, this action would update the name and geographic coordinates of Dekalb Regional Medical Center Heliport, which is contained within the legal description of the Isbell Field Airport airspace.

The Environmental Protection Agency (EPA) is proposing to approve a revision to the New Jersey State Implementation Plan (SIP) for the 2008 8-hour ozone National Ambient Air Quality Standard in relation to a Source Specific SIP for Gerdau Ameristeel in Sayreville, New Jersey. On December 5, 2018, the New Jersey Department of Environmental Protection approved an administrative amendment reflecting new ownership and name change to Commercial Metals Company. The control options in the Source Specific SIP that address nitrogen oxide Reasonably Available Control Technology for the natural gas fired billet reheat furnace remain the same under the new ownership. The intended effect of this SIP revision is for the Sayreville facility to continue to operate under their facility specific maximum allowable nitrogen oxide emission rate. The affected source will not increase hourly nitrogen oxide emissions, therefore, the National Ambient Air Quality Standards for ozone is protected.

This action proposes to establish restricted area R-7205 on the island of Guam, GU. The US Army has been operating a Terminal High Altitude Area Defense (THAAD) radar system in direct support of national defense initiatives. The system has operated within a Temporary Flight Restriction (TFR) for over five years. The restricted area is necessary to protect aviation from hazardous electro-magnetic radiation and segregate non-participating aircraft.
