April 5, 2012 – Federal Register Recent Federal Regulation Documents

EPA is proposing to approve Indiana's request to revise its Central Indiana 1997 8-hour ozone maintenance air quality State Implementation Plan (SIP) by replacing the previously approved motor vehicle emissions budgets (budgets) with budgets developed using EPA's Motor Vehicle Emissions Simulator (MOVES) 2010a emissions model. The Central Indiana 1997 8-hour ozone maintenance area consists of Marion, Boone, Hendricks, Morgan, Johnson, Shelby, Hancock, Madison, and Hamilton Counties in Indiana. Indiana submitted this request to EPA for parallel processing on March 2, 2012.

EPA is proposing to amend the federal regulations to withdraw human health and aquatic life water quality criteria applicable to certain waters of New Jersey, Puerto Rico, and California's San Francisco Bay, now that those States have adopted and EPA has approved relevant state criteria. EPA is seeking public comment on its action with respect to those state criteria that are less stringent than the federally promulgated criteria. The withdrawal of the federally promulgated criteria will enable New Jersey, Puerto Rico, and California to implement their EPA-approved water quality criteria.

In 2010, Congress transferred the statute authorizing the FAA's commercial space transportation regulations. This action is necessary to correct affected citations in the Code of Federal Regulations to reflect this transfer of authority. The intended effect of this action is to make the affected regulations comply with the statute.

The Office of Natural Resources Revenue (ONRR) announces meetings for the Indian Oil Valuation Negotiated Rulemaking Committee (Committee). Agenda items for the first meetings of the Committee will include (1) an overview of Indian oil production, the current Indian oil valuation rule, and the Indian oil royalty administrative process; (2) an identification of issues to be addressed by the Committee; and (3) an opportunity for members to express their issues, concerns and interests. In addition, the Committee's facilitator will review meeting protocols and facilitate a discussion of collaborative problem solving. The Committee membership includes representatives from Indian Tribes, individual Indian mineral owner organizations, the oil and gas industry, and the Department of the Interior. The public will have the opportunity to comment between 3:45 p.m. and 4:45 p.m. mountain standard time on May 1, 2012, and June 18, 2012.

We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-Trent 875-17, RB211-Trent 877-17, RB211-Trent 884-17, RB211-Trent 884B-17, RB211-Trent 892-17, RB211- Trent 892B-17, and RB211-Trent 895-17 turbofan engines. That AD currently requires initial and repetitive ultrasonic inspections (UIs) of certain low-pressure (LP) compressor blades identified by serial number (S/N). This AD requires the same actions but expands the population of blades. This AD was prompted by RR concluding that additional blades affected must be inspected. We are issuing this AD to prevent LP compressor blades from failing due to blade root cracks, which could lead to uncontained engine failure and damage to the airplane.

This document adopts amendments to the Federal motor vehicle safety standards on platform lift systems for motor vehicles. The purpose of these standards is to prevent injuries and fatalities during lift operation. NHTSA believes it is necessary to revise the lighting requirements for lift controls; the location requirements, performance requirements, and test specifications for threshold warning signals; the wheelchair retention device and inner roll stop tests; and the lighting requirements for public use lifts. This notice also discusses a November 3, 2005 interpretation clarifying specific procedures that are performed as part of the threshold warning signal test.

In this document, the Commission conditionally waives the requirement for National Deaf Blind Equipment Distribution Program (NDBEDP) certified programs to submit reimbursement claims only once every six months, to permit certified programs to submit reimbursement claims as frequently as monthly. The Commission waives this requirement for good cause shown, to reduce the financial burden on programs that the Commission certifies to participate in the NDBEDP, and to better enable selected participants to fully meet the needs of eligible low- income, deaf-blind individuals in a timely manner.

We propose to adopt a new airworthiness directive (AD) for certain BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 and Model Avro 146-RJ airplanes. This proposed AD was prompted by reports of cracking and surface anomalies of the fuselage skin at the water trap/air drier unit of the forward discharge valve due to corrosion. This proposed AD would require repetitive detailed inspections for bulging, surface anomalies, and cracking of the fuselage skin adjacent to the discharge valves, repair if necessary, and application of additional sealant in the affected area if necessary. We are proposing this AD to detect and correct bulging, surface anomalies, and cracking that could propagate towards the forward discharge valve outlet and result in the failure of the fuselage skin, leading to a possible sudden loss of cabin pressure.

We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 helicopters with certain tail rotor blades (blades) installed. This AD requires, before further flight, removing and replacing each affected blade with an airworthy blade. This AD is prompted by incidents where a blade tip weight separated from a blade in flight on other model helicopters with common part-numbered blades. It has been determined that this unsafe condition may also exist on the specified Agusta model helicopters. The actions specified in this AD are intended to prevent loss of the blade tip weight, loss of a blade, and subsequent loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for all Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This AD was prompted by reports that the horizontal stabilizer trim actuator (HSTA) no-back and the number 1 motor brake assembly (MBA) can both fail dormant. This AD requires revising the airplane maintenance schedule to include new functional tests of the HSTA no-back and HSTA brake system. We are issuing this AD to prevent dormant failure of the HSTA no-back and the number 1 MBA, which along with additional component failure could result in an uncontrollable horizontal stabilizer surface runaway without the ability to retrim, and consequent loss of the airplane.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD was prompted by reports of heat damage to the inner wall of the thrust reversers, which could result in separation of adjacent components and consequent structural damage to the airplane, damage to other airplanes, and injury to people on the ground. This AD requires modifying the thrust reverser inner walls, inspecting for damage of the upper and lower inner wall insulation blankets, measuring the electrical conductivity on the aluminum upper compression pads 2 and 3 as applicable, inspecting for discrepancies of the inner wall of the thrust reverser, and corrective actions if necessary. This AD also requires, for certain airplanes, doing various concurrent actions (including replacing the inner wall blanket insulation, installing updated full-authority digital electronic control software, and modifying the thrust reverser inner wall and insulation blankets). We are issuing this AD to correct the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all Airbus Model A340-500 and -600 series airplanes. This AD requires repetitive inspections of the forward and aft attachment fittings and of the swan neck for cracks, and replacing the attachment fittings and the swan neck with serviceable ones if necessary. This AD was prompted by reports of cracks on the forward attachment fittings of the left and right sides of the forward hinge of the nose landing gear (NLG) aft door. We are issuing this AD to detect and correct cracks of the forward attachment fittings and the swan neck, which could lead to the in-flight detachment of the NLG aft door and result in injury to persons on the ground or damage to the airplane.

In this document, the Federal Communications Commission clarifies certain rules. The order clarifies, but does not otherwise modify, the USF/ICC Transformation Order. The petition for Clarification or, in the Alternative, for Reconsideration of Verizon is granted in part and dismissed in part, and the Petition for Reconsideration of United States Telecom Association is dismissed in part.
