April 2016 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2500-A1 turbofan engines. This proposed AD was prompted by a report of an uncontainment caused by a high-pressure turbine (HPT) seal release. This proposed AD would require removing from service the HPT No. 4 bearing front seal seat, part numbers (P/Ns) 2A0066, 2A1998, and 2A3432, and the HPT No. 4 bearing rear seal seat, P/Ns 2A0067, 2A1999, and 2A3433, and replacement with parts eligible for installation. This proposed AD would also require inspecting the HPT rotor and stator assembly, and, if necessary, their replacement with parts that are eligible for installation. We are proposing this AD to prevent failure of the HPT stage 2 seals, uncontained HPT seal release, damage to the engine, and damage to the airplane.

This action proposes to amend Class D and E airspace at Sioux Gateway/Col. Bud Day Field, Sioux City, IA, due to the decommissioning of the Gateway non-directional radio beacon (NDB) and cancellation of the NDB approaches at the airport. The Class E airspace area designated as an extension would be removed as it is no longer needed. Advances in Global Positioning System (GPS) capabilities have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also would update the geographic coordinates for Martin Field, NE, to coincide with the FAA's aeronautical database.

The Environmental Protection Agency (EPA) is proposing to make a finding of attainment by the attainment date for the Klamath Falls, Oregon nonattainment area (the area) based upon quality-assured, quality-controlled, and certified ambient air monitoring data showing that the area has monitored attainment of the 2006 24-hour fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS) based on the 2012-2014 data available in the EPA's Air Quality System (AQS) database. The proposed finding of attainment does not constitute a redesignation to attainment. Redesignations require states to meet a number of criteria including EPA approval of a state plan to maintain the air quality standard for 10 years after redesignation. The EPA also proposes to approve revisions to Oregon's State Implementation Plan (SIP) consisting of the Klamath Falls Fine Particulate Matter Attainment Plan (attainment plan) and approve and incorporate by reference associated revisions to the Oregon Administrative Rules (OAR), submitted by the Oregon Department of Environmental Quality (ODEQ) on December 12, 2012. The purpose of the attainment plan was to attain the 2006 24-hour PM2.5 NAAQS by the December 2014 attainment date included in the plan, which the area met based on 2012-2014 monitoring data. The attainment plan addressed the nonattainment planning requirements of the Clean Air Act (CAA or Act). The attainment plan included comprehensive base year and attainment year emissions inventories for direct PM2.5 emissions and all particulate matter precursors, analysis and selection of reasonably available control measures and reasonably available control technologies (RACM and RACT), demonstrated attainment through selected permanent and enforceable control strategies, included required contingency measures, and addressed reasonable further progress and quantitative milestone requirements through the attainment demonstration. The attainment plan's strategy for controlling direct and precursor PM2.5 emissions relied primarily on an episodic woodstove curtailment program and a program to change-out uncertified woodstoves. Additional emissions reductions came from control measures and activities associated with industrial sources and motor vehicles.

We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. The NPRM proposed an inspection for plastic couplings, corrective actions if necessary, and installation of new spray shrouds. The NPRM was prompted by a report of the engine indication and crew alerting system (EICAS) display system malfunctioning during flight. This action revises the NPRM by adding, for certain airplanes, a general visual inspection of the spray shield and related investigative and corrective actions if necessary. We are proposing this supplemental NPRM (SNPRM) to prevent an uncontrolled water leak from a defective potable water system coupling, which could cause the main equipment center (MEC) line replaceable units (LRUs) to become wet, resulting in an electrical short and potential loss of several functions essential for safe flight. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300- 600 series airplanes), modified by a particular supplemental type certificate (STC). This AD was prompted by a report of chafing found on the overflow sensor harness of the surge tank, and subsequent contact between the electrical wiring and fuel tank structure. This AD requires a one-time inspection for damage of the outer tank overflow sensor harness, and repair if necessary. This AD also requires modification of the sensor harness. We are issuing this AD to prevent chafing of the harness and subsequent contact between the electrical wiring and fuel tank structure, which could result in electrical arcing and a fuel tank explosion.

We propose to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-235-300 airplanes. This proposed AD was prompted by reports of main landing gear (MLG) access doors detaching from the airplane as a result of excessive vibration and metal fatigue in the attach fittings. This proposed AD would require modification of the MLG access door by replacing seals in the MLG fairing and, for certain airplanes, adding an additional bolt. We are proposing this AD to prevent a fracture in the MLG access door associated with excessive vibration and metal fatigue in the attach fittings. This condition could lead to MLG access door detachment and consequent impact of flight controls, resulting in reduced control of an airplane.

We are superseding Airworthiness Directive (AD) 2013-22-11 for certain The Boeing Company Model 747-400 and -400D series airplanes. AD 2013-22-11 required repetitive inspections to detect cracks in the floor panel attachment fastener holes of certain upper deck floor beam upper chords, repetitive inspections, corrective actions if necessary, and replacement of the upper deck floor beam upper chords. Since we issued AD 2013-22-11, we received a report that certain fastener holes in the upper deck floor beam upper chords may not have been inspected in accordance with AD 2013-22-11. This AD adds additional repetitive inspections for cracks for certain airplanes, and corrective actions if necessary. We are issuing this AD to detect and correct fatigue cracking in certain upper chords of the upper deck floor beam. Such cracks could become large and cause the floor beams to become severed and result in rapid decompression or reduced controllability of the airplane.

We are superseding airworthiness directive (AD) 92-06-10 for SOCATA Models MS 880B, MS 885, MS 892A-150, MS 892E-150, MS 893A, MS 893E, MS 894A, MS 894E, Rallye 100S, Rallye 150ST, Rallye 150T, Rallye 235E, and Rallye 235C airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fatigue failure of the nose landing gear wheel axle. We are issuing this AD to require actions to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is approving revisions to the State Implementation Plan (SIP) submitted by the State of Texas through the Texas Commission on Environmental Quality (TCEQ) on July 10, 2015. The Texas SIP submission revises 30 Texas Administrative Code (TAC) Chapter 117 rules for control of nitrogen compounds to assist the Dallas-Fort Worth (DFW) moderate nonattainment area (NAA) in attaining the 2008 eight-hour ozone (O3) National Ambient Air Quality Standards (NAAQS).

The United States Department of Agriculture's (USDA) Agricultural Marketing Service (AMS) proposes to amend the organic livestock and poultry production requirements by: adding new provisions for livestock handling and transport for slaughter and avian living conditions; and expanding and clarifying existing requirements covering livestock health care practices and mammalian living conditions.

The Environmental Protection Agency (EPA) is revising portions of the Arizona Regional Haze Federal Implementation Plan (FIP) applicable to the Coronado Generating Station (Coronado) and the Cholla Power Plant (Cholla). In response to a petition for reconsideration from the Salt River Project Agricultural Improvement and Power District (SRP), the owner and operator of Coronado, we are replacing a plant- wide compliance method with a unit-specific compliance method for determining compliance with the best available retrofit technology (BART) emission limits for nitrogen oxides (NOX) from Units 1 and 2 at Coronado. While the plant-wide limit for NOX emissions from Units 1 and 2 was established as 0.065 lb/MMBtu, we are now setting a unit-specific limit of 0.065 lb/MMBtu for Unit 1 and 0.080 lb/MMBtu for Unit 2. In addition, we are revising the work practice standard in the FIP for Coronado. Finally, we are removing the affirmative defense for malfunctions, which applied to both Coronado and Cholla.

NMFS is exchanging unused rock sole Community Development Quota (CDQ) for yellowfin sole CDQ acceptable biological catch (ABC) reserves in the Bering Sea and Aleutian Islands management area. This action is necessary to allow the 2016 total allowable catch of rock sole, and yellowfin sole in the Bering Sea and Aleutian Islands management area to be harvested.

NMFS closes the southern area Angling category fishery for large medium and giant (``trophy'' (i.e., measuring 73 inches curved fork length or greater)) Atlantic bluefin tuna (BFT). This action is being taken to prevent any further overharvest of the Angling category southern area trophy BFT subquota.

The Coast Guard is establishing special local regulations for certain waters of the Chesapeake Bay. This action is necessary to provide for the safety of life on these navigable waters located between Sandy Point, Anne Arundel County, MD and Kent Island, Queen Anne's County, MD, during a paddling event on May 14, 2016. This rulemaking will prohibit persons and vessels from being in the regulated area unless authorized by the Captain of the Port Baltimore or Coast Guard Patrol Commander.

In the November 2, 2015 Federal Register, we published a final rule with comment period entitled ``Medicaid Program: Methods for Assuring Access to Covered Medicaid Services.'' The final rule with comment period established that states must develop and submit to CMS an access monitoring review plan by July 1, 2016. This document revises the deadline for states' access monitoring review plan submission to CMS until October 1, 2016.

We, the U.S. Fish and Wildlife Service, published a final rule in the Federal Register on March 28, 2016, that prescribes final frameworks from which States may select season dates, limits, and other options for the 2016-17 migratory bird hunting seasons. In that rule, we made an error in the daily bag limit for canvasbacks in Alaska. We intended to increase the daily bag limit for canvasbacks in Alaska, as we did for the rest of the United States, to 2 birds. We also included an incorrect description for the Special Early Canada Goose Unit in South Dakota. With this document, we correct our errors.

The Commission is proposing rules which amend existing rules related to the Mail Classification Schedule and its associated product lists. The proposed rules revise some existing rules in order to better conform with current Commission practices related to the Mail Classification Schedule. The Commission invites public comment on the proposed rules.

The Coast Guard has issued a temporary deviation from the operating schedule that governs the Route 82 Bridge across the Connecticut River, mile 16.8, at East Haddam, Connecticut. This deviation is necessary to allow the bridge owner to perform emergency repairs at the bridge.

The Environmental Protection Agency (EPA) published in the January 25, 2016 Federal Register a document concerning the approval of Air Quality State Implementation Plan (SIP) revisions to Colorado Common Provisions and Regulation Number 3. Inadvertently, the publication date of January 25, 2016 was listed in the regulatory text under the heading ``EPA Effective Date'' instead of the effective date of February 24, 2016. The correct EPA effective date was provided in the rule preamble. This document corrects the ``EPA Effective Date'' within the regulatory text to February 24, 2016.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by a design review, which found that the burst pressure of the flexible hose used to vent oxygen from the high- pressure relief valve of the oxygen cylinder overboard is lower than the opening pressure of the high-pressure relief valve. This pressure difference could cause the flexible hose to burst before it is able to vent excess oxygen overboard. This proposed AD would require replacement of flexible relief hoses for the crew oxygen bottles with new metal design relief hoses. We are proposing this AD to prevent the accumulation of excess oxygen in an enclosed space, which could, if near a source of ignition, cause an uncontrolled oxygen-fed fire.

We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL (type certificate previously held by Pacific Aerospace Corporation Ltd.) airplanes that would supersede AD 2006-13-05. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as some critical rivets on the wing not being fully age- hardened and being installed in specific locations where reduction in rivet strength reduces wing strength. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter and -300 series airplanes, and Model A340-200 and -300 series airplanes. This proposed AD was prompted by reports of spurious terrain awareness warning system (TAWS) alerts during approach and takeoff for airplanes fitted with the terrain and traffic collision avoidance system with transponder (T3CAS) when the T3CAS is constantly powered ``ON'' for more than 149 hours. This proposed AD would require repetitive on-ground power cycle of the T3CAS. We are proposing this AD to prevent spurious TAWS alerts (Collision Prediction and Alerting (CPA), or missing legitimate CPA), which could increase flight crew workload during critical landing or takeoff phases, and possibly result in reduced control of the airplane.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), Model CL-600- 2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports of corrosion found on the slat and flap torque tubes in the slat and flap control system. This proposed AD would require replacement of the slat and flap torque tubes in the slat and flap control system. We are proposing this AD to prevent rupture of a corroded slat or flap torque tube. This condition could result in an inoperative slat or flap system and consequent reduced controllability of the airplane.

The Environmental Protection Agency (EPA) is finalizing a revision to the Federal implementation plan (FIP) addressing the requirement for best available retrofit technology (BART) for taconite plants in Minnesota and Michigan. In response to petitions for reconsideration, we are revising the nitrogen oxides (NOX) limits for taconite furnaces at facilities owned and operated by Cliffs Natural Resources (Cliffs) and ArcelorMittal USA LLC (ArcelorMittal). Cliffs owns and operates Tilden Mining and United Taconite. Hibbing is owned by Cliffs, ArcelorMittal and U.S. Steel and operated by Cliffs. ArcelorMittal is owner and operator of Minorca Mine. We are also revising the sulfur dioxide (SO2) requirements at two of Cliffs' facilities. We are making these changes because new information has come to light that was not available when we originally promulgated the FIP on February 6, 2013.

The Environmental Protection Agency (EPA) proposes to disapprove the portion of a Texas State Implementation Plan (SIP) submittal pertaining to interstate transport of air pollution which will significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone National Ambient Air Quality Standards (NAAQS) in other states. Disapproval will establish a 2-year deadline for the EPA to promulgate a Federal Implementation Plan (FIP) for Texas to address the Clean Air Act (CAA) interstate transport requirements pertaining to significant contribution to nonattainment and interference with maintenance of the 2008 ozone NAAQS in other states, unless the EPA approves a SIP that meets these requirements. Disapproval does not start a mandatory sanctions clock for Texas.
