May 10, 2010 – Federal Register Recent Federal Regulation Documents

The Office of Federal Procurement Policy (OFPP), Cost Accounting Standards Board (Board), invites public comments concerning the harmonization of Cost Accounting Standards 412 and 413 with the Pension Protection Act (PPA) of 2006. The PPA amended the minimum funding requirements for defined benefit pension plans. The PPA required the Board to harmonize with PPA the CAS applicable to the Government reimbursement of the contractor's pension costs. The Board has proposed several changes to harmonize CAS with PPA, including the recognition of a ``minimum actuarial liability'' consistent with the PPA minimum required contribution. The proposed CAS changes will lessen the difference between the amount of pension cost reimbursable to the contractor in accordance with CAS and the amount of pension contribution required to be made by the contractor as the plan sponsor by PPA.

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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: During ground maneuvering, prolonged operation with either engine in the restricted range between 82% and 90% RPM [revolutions per minute] will result in damage [e.g., cracking of the blade or hub] to the propeller assembly that could eventually result in the release of a propeller blade. EASA AD 2007- 0268 [which corresponds to FAA AD 2008-13-02] was issued to require the installation of a Propeller Warning Placard and implementation of a corresponding Aircraft Flight Manual (AFM) limitation instructing the flight crew to taxi with the condition lever at FLIGHT in order to minimise the time spent by the engines in the restricted range. BAE Systems has now developed a Propeller Speed Warning System.

Pursuant to the U.S. Environmental Protection Agency's Significant New Alternatives Policy program, this action proposes to list isobutane, propane, HCR-188C, and HCR-188C1 as ``acceptable, subject to use conditions,'' as substitutes for chlorofluorocarbon (CFC)-12, also referred to as R-12, CCl2F2 and dichlorodifluoromethane and hydrochlorofluorocarbon (HCFC)-22, also referred to as R-22, CHClF2, chlorodifluoromethane and difluorochloromethane, in household refrigerators, freezers, and combination refrigerator and freezers and commercial refrigeration (retail food refrigerators and freezersstand-alone units only).

The Commander, Eighth Coast Guard District, has issued a temporary deviation from the regulation governing the operation of the Burlington Northern Santa Fe Railroad swing span bridge across the Mermentau River, mile 68.0, at Mermentau, Acadia and Jefferson Davis Parishes, Louisiana. The deviation is necessary to replace the top flanges on four floor beams. This deviation allows the bridge to remain closed to navigation for ten days.

EPA is proposing to approve revisions to the Yolo-Solano Air Quality Management District (YSAQMD) portion of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NOx) emissions from natural gas-fired water heaters, small boilers and nitric acid production facilities. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

With this action, EPA is allocating essential use allowances for import and production of Class I ozone-depleting substances (ODSs) for calendar year 2010. Essential use allowances enable a person to obtain controlled Class I ODSs through an exemption to the regulatory ban on the production and import of these chemicals, which became effective as of January 1, 1996. EPA allocates essential use allowances for production or import of a specific quantity of Class I substances solely for the designated essential purpose. The allocation in this action is 30.0 metric tons (MT) of chlorofluorocarbons (CFCs) for use in metered dose inhalers (MDIs) for 2010.

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:

EPA is proposing to amend certain of the Renewable Fuel Standard program regulations published on March 26, 2010, that are scheduled to take effect on July 1, 2010 (the ``RFS2 regulations''). Following publication of the RFS2 regulations, promulgated in response to the requirements of the Energy Independence and Security Act of 2007, EPA discovered some technical errors and areas within the final RFS2 regulations that could benefit from clarification or modification. This proposed rule would amend the RFS2 regulations to make the appropriate corrections, clarifications, and modifications.

EPA is approving a request submitted by the Ohio Environmental Protection Agency (Ohio EPA) on March 17, 2009, to revise the Ohio State Implementation Plan (SIP) under the Clean Air Act (CAA). The State has submitted revisions to rules for approval under Ohio Administrative Code (OAC) Chapter 3745-15, ``General Provisions,'' which include the adoption of the Federal definition and citation of the CAA, and clarifications for exemptions and new requirements for sources regulated under the Title V permitting program. These revisions are included in OAC 3745-15-01 and OAC 3745-15-05, respectively.

This establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

FRA is proposing to amend the Track Safety Standards and Passenger Equipment Safety Standards applicable to high-speed and high cant deficiency train operations in order to promote the safe interaction of rail vehicles with the track over which they operate. The proposal would revise existing limits for vehicle response to track perturbations and add new limits as well. The proposal accounts for a range of vehicle types that are currently used and may likely be used on future high-speed or high cant deficiency rail operations, or both. The proposal is based on the results of simulation studies designed to identify track geometry irregularities associated with unsafe wheel/ rail forces and accelerations, thorough reviews of vehicle qualification and revenue service test data, and consideration of international practices.

EPA is proposing to approve State Implementation Plan revisions submitted by the State of Colorado on August 3, 2007 to Colorado's Regulation Number 1 (revisions to the performance testing requirements for air curtain destructors). Colorado adopted these rule revisions on October 2, 2006. All other actions submitted by the State of Colorado concurrent with Colorado's Regulation Number 1 revision request will be acted on at a later date. In the ``Rules and Regulations'' section of this Federal Register, EPA is approving the State's SIP revision as a direct final rule without prior proposal because the Agency views this as a non-controversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule. If EPA receives adverse comments, EPA will withdraw the direct
