May 10, 2010 – Federal Register Recent Federal Regulation Documents

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:

The DHS Data Privacy and Integrity Advisory Committee will meet on May 25, 2010, in Washington, DC. The meeting will be open to the public.

EPA is taking direct final action 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 direct final rule amends the RFS2 regulations to make the appropriate corrections, clarifications, and modifications.

EPA is proposing to approve 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 Chapter 3745-15, ``General Provisions,'' of the Ohio Administrative Code (OAC). The State's revisions to OAC 3745-15-01 include adoption of the Federal definition and citation of the CAA, and the revisions to OAC 3745-15-05 include clarifications for exemptions and new requirements for sources regulated under Title V.

This rule 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
