This action revises Class E airspace at St. Mary's, AK, to provide adequate controlled airspace to contain aircraft executing Standard Instrument Approach Procedures (SIAPs). Two new SIAPs are being developed for the St. Mary's Airport. Additionally, four SIAPs are being amended. This action revises existing Class E airspace upward from the surface and from 700 feet (ft.) above the surface at St. Mary's Airport, St. Mary's, AK.

The U.S. Environmental Protection Agency (EPA) is announcing the availability of the second external review draft of a document titled, ``Draft Integrated Science Assessment for Sulfur OxidesHealth Criteria'' (EPA/600/R-08/047). The document was prepared by the National Center for Environmental Assessment within EPA's Office of Research and Development as part of the review of the primary (health- based) national ambient air quality standards (NAAQS) for sulfur oxides. EPA is releasing this draft document solely for the purpose of seeking public comment and for review by the Clean Air Scientific Advisory Committee (CASAC) (meeting date and location to be specified in a separate Federal Register notice). It does not represent and should not be construed to represent any Agency policy, viewpoint, or determination. EPA will consider any public comments submitted in accordance with this notice when revising the document.

This action establishes four low altitude Area Navigation (RNAV) T-routes, designated T-257, T-259, T-261 and T-263, in the Sacramento and San Francisco, CA, terminal areas. T-routes are low altitude Air Traffic Service (ATS) routes, based on RNAV, for use by aircraft having instrument flight rules (IFR)-approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The FAA is taking this action to enhance safety and improve the efficient use of the navigable airspace in the Sacramento and San Francisco, CA, terminal areas.

On February 27, 2003, Southwest Gulf Railroad Company (SGR) filed a petition with the Surface Transportation Board (Board) pursuant to 49 U.S.C. 10502 for authority to construct and operate a rail line approximately seven miles long from a Vulcan Construction Materials, LP (VCM) proposed limestone quarry to a Union Pacific Railroad Company (UP) rail line near Dunlay, Texas. SGR proposed construction and operation of the rail line to transport limestone aggregate from VCM's proposed quarry to the UP rail line. SGR anticipates operating approximately four trains per day (comprising two inbound empty and two outbound loaded trains). Each train would consist of 100 railcars. The Board's Section of Environmental Analysis (SEA) has prepared the FEIS was pursuant to the National Environmental Policy Act of 1969 (NEPA), 42 United States Code (U.S.C.) 4231 et seq. Under NEPA, the Board must consider the environmental impacts of actions requiring Board authorization and complete its environmental review before making a final decision on a proposed action. SEA is the office within the Board that carries out the Board's responsibilities and related environmental laws and regulations, including the Council on Environmental Quality's (CEQ) regulations for implementing NEPA at 40 CFR Part 1500; the Board's environmental regulations at 49 CFR Part 1105; and the Section 106 National Historic Preservation Act of 1966 (NHPA) process.

The FAA is superseding an existing airworthiness directive (AD) for RR RB211 Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61 turbofan engines. That AD currently requires removing certain serial-numbered intermediate pressure compressor (IPC) drums, part number (P/N) FK30102. This AD requires removing those same IPC drums, and requires a new reduced life limit for all other IPC drums, P/N FK30102. This AD results from an RR engineering assessment that it is necessary to reduce the cyclic lives of the other drums with the same P/N. We are issuing this AD to prevent uncontained loss of IPC stage 1 blades, which could result in damage to the airplane.
