October 19, 2007 – Federal Register Recent Federal Regulation Documents

This document proposes superseding an existing airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model 600N helicopters. That AD currently requires interim initial and repetitive inspections of tailboom parts, installing six inspection holes in the aft fuselage skin panels, installing tailboom attachment bolt washers, modifying both access covers, and replacing broken attachment bolts. The current AD also provides for modifying the fuselage aft section as an optional terminating action. This proposal would mandate modifying the fuselage aft section within the next 24 months to strengthen the tailboom attachment fittings and upper longerons. The actions specified by the proposed AD are intended to prevent failure of the tailboom attachment fittings, separation of the tailboom from the helicopter, and subsequent loss of control of the helicopter.

This proposed rule would require that export and reexport license applications, classification requests, encryption review requests, License Exception AGR notifications and related documents be submitted to the Bureau of Industry and Security (BIS) via its Simplified Network Application Process (SNAP-R) system. This requirement would not apply to applications for Special Comprehensive Licenses or in certain situations in which BIS would authorize paper submissions.

NMFS suspends the minimum size limit of 4.75 inches (120 mm) for Atlantic surfclams for the 2008 fishing year. This action is taken under the authority of the implementing regulations for this fishery, which allow for the annual suspension of the minimum size limit based upon set criteria. The intended effect is to relieve the industry from a regulatory burden that is not necessary, as the majority of surfclams harvested are larger than the minimum size limit.

We propose to supersede Airworthiness Directive (AD) 2007-13- 11, which applies to all Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes. AD 2007-13-11 was prompted by reports of loss of primary airspeed indication due to freezing condensation within the pitot system. AD 2007-13-11 requires operational limitations consisting of operation only in day visual flight rules (VFR), allowing only a VFR flight plan, and maintaining operation with two pilots. Since we issued AD 2007-13-11, Eclipse has developed a design modification to the pitot/angle-of-attack (AOA) system to eliminate the possibility of freezing condensation within the pitot/AOA system. Eclipse is incorporating this modification during production on Model EA500 airplanes starting with serial number (S/N) 000065. Consequently, this proposed AD would limit the applicability to airplanes under S/N 000065 and require incorporating the modification. This proposed AD would also retain the operating limitations in AD 2007-13-11 until the modification is incorporated. We are proposing this AD to prevent long- term reliance on special operating limitations when a design change exists that would eliminate the need for the operating limitations. Incorporating the proposed modification would prevent loss of air pressure in the pitot system, which could cause erroneous AOA and airspeed information with consequent loss of control.

The Department of Agriculture (USDA) is adopting, as a final rule, without change, an interim final rule that established final volume regulation percentages for 2006-07 crop Natural (sun-dried) Seedless (NS) raisins covered under the Federal marketing order for California raisins (order). The order regulates the handling of raisins produced from grapes grown in California and is locally administered by the Raisin Administrative Committee (Committee). The volume regulation percentages are 90 percent free and 10 percent reserve. The percentages are intended to help stabilize raisin supplies and prices, and strengthen market conditions.

On March 26, 2007, the Indiana Department of Environmental Management (IDEM) submitted a request for EPA approval of a redesignation of Boone, Hamilton, Hancock, Hendricks, Johnson, Madison, Marion, Morgan, and Shelby Counties (the Central Indiana Area) to attainment of the 8-hour ozone National Ambient Air Quality Standard (NAAQS). IDEM also requested EPA approval of an ozone maintenance plan for this area as a revision of the Indiana State Implementation Plan (SIP). The maintenance plan demonstrates maintenance of the ozone NAAQS in this area through 2020 and establishes 2006 and 2020 motor vehicle Volatile Organic Compounds (VOC) and Nitrogen Oxides (NOX) emission budgets for this area. EPA is making a determination that the Central Indiana Area has attained the 8-hour ozone NAAQS. EPA is approving, as a SIP revision, the State's ozone maintenance plan for this area. Indiana has satisfied the criteria for the redesignation of the Central Indiana Area to attainment of the 8-hour ozone NAAQS, and, therefore, EPA is approving Indiana's ozone redesignation request for this area. Further, EPA is approving, for purposes of transportation conformity, the VOC and NOX Motor Vehicle Emission Budgets (MVEBs) for 2006 and 2020 that are contained in the 8-hour ozone maintenance plan. EPA proposed these actions on July 31, 2007, and received only one comment in response supporting the proposed actions.

EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The Pennsylvania Department of Environmental Protection (PADEP) is requesting that the Mercer County portion of the Youngstown-Warren-Sharon, OH-PA 8-hour ozone nonattainment area (``Youngstown Area'' or ``Area'') be redesignated as attainment for the 8-hour ozone ambient air quality standard (NAAQS). The Area is comprised of Mercer County, Pennsylvania and Trumbull, Mahoning, and Columbiana Counties, Ohio. EPA is approving the ozone redesignation request for Mercer County. In a separate rulemaking action (72 FR 32190, June 12, 2007) EPA approved the ozone redesignation request for Trumbull, Mahoning, and Columbiana Counties, Ohio. In conjunction with its redesignation request, PADEP submitted a SIP revision consisting of a maintenance plan for Mercer County that provides for continued attainment of the 8-hour ozone NAAQS for at least 10 years after redesignation. EPA is approving the 8-hour maintenance plan. PADEP also submitted a 2002 base year inventory for Mercer County which EPA is approving. In addition, EPA is approving the adequacy determination for the motor vehicle emission budgets (MVEBs) that are identified in the Mercer County maintenance plan for purposes of transportation conformity, and is approving those MVEBs. EPA is approving the redesignation request, and the maintenance plan and the 2002 base year emissions inventory as revisions to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).

The Clean Air Interstate Rule (CAIR), CAIR Federal Implementation Plans (FIPs), and Clean Air Mercury Rule (CAMR) each include an exemption for cogeneration units that meet certain criteria. In light of information concerning biomass-fired cogeneration units that may not qualify for the exemption due to their particular combination of fuel and technical design characteristics, EPA is changing the cogeneration unit definition in CAIR, the CAIR model cap- and-trade rules, the CAIR FIPs, CAMR, and the CAMR model cap-and-trade rule. Specifically, EPA is revising the calculation methodology for the efficiency standard in the cogeneration unit definition to exclude energy input from biomass making it more likely that units co-firing biomass will be able to meet the efficiency standard and qualify for exemption. Because this change will only affect a small number of relatively low emitting units, it will have little effect on the projected emissions reductions and the environmental benefits of these rules. If EPA finalizes the proposed CAMR Federal Plan, it intends to make the definitions in that rule conform to the CAMR model cap-and- trade rule and thus, with today's action. This action also clarifies the term ``total energy input'' used in the efficiency calculation and makes minor technical corrections to CAIR, the CAIR FIPs, CAMR, and the Acid Rain Program rules.

We are revising the criteria in the Listing of Impairments (the listings) that we use to evaluate claims involving digestive disorders. We apply these criteria when you claim benefits based on disability under title II and title XVI of the Social Security Act (the Act). The revisions reflect advances in medical knowledge, methods of evaluating digestive disorders, treatment, and our program experience. We are also removing listings that are redundant because they only refer to other listings, and we are making other conforming changes.

In accordance with Section 651e of the Energy Policy Act of 2005, the U.S. Nuclear Regulatory Commission is publishing a ``Plan for the Transition of Regulatory Authority Resulting from the Expanded Definition of Byproduct Material'' (transition plan) to facilitate an orderly transition of regulatory authority with respect to the byproduct material defined in paragraphs (3) and (4) of section 11e. of the Atomic Energy Act of 1954, as amended. A copy of the final transition plan is provided as Appendix A to this document.
