Approval and Promulgation of Air Quality Implementation Plan: Kentucky; Approval Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard for the Paducah Area; Limited Reopening of Comment Period
Document Number: 2010-3838
Type: Proposed Rule
Date: 2010-02-25
Agency: Environmental Protection Agency
EPA is announcing a 30-day reopening of the public comment period for the proposed rule entitled ``Approval and Promulgation of Air Quality Implementation Plan: Kentucky; Approval Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard for the Paducah Area,'' for the purpose of limited public review and comment of supplemental information that was provided by the Commonwealth of Kentucky on July 15, 2009, in support of the Paducah Area 110(a)(1) maintenance plan. The Paducah, KY Area consists of Marshall and a portion of Livingston Counties. The proposed rule was initially published in the Federal Register on January 4, 2010. The reason for this limited reopening of the comment period is that EPA has learned that supplemental information relating to projected emissions for the Paducah Area that was referenced in the proposed rulemaking January 4, 2010 (75 FR 97) was inadvertently omitted from the electronic docket when that proposed rulemaking was published. EPA has since made that information available in the electronic docket and wants to ensure an opportunity for the public to comment on that information. The July 15, 2009 supplemental information can be viewed online at https:// www.regulations.gov using docket ID No. EPA-R04-OAR-2007-1186-0043.

Airworthiness Directives; Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) Airplanes
Document Number: 2010-3827
Type: Proposed Rule
Date: 2010-02-25
Agency: Federal Aviation Administration, Department of Transportation
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:
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135ER, -135KE, -135KL, and -135LR Airplanes; and EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes

Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; The Boeing Company Model 747-100, -200B, and -200F Series Airplanes
Document Number: 2010-3819
Type: Proposed Rule
Date: 2010-02-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Model 747-100, 747-200B, and - 200F series airplanes. The existing AD currently requires inspections to detect cracking in the upper row of fasteners holes of the skin lap joints in the fuselage lower lobe, and repair, if necessary. This proposed AD would reduce the maximum interval of the post-modification inspections. This proposed AD results from reports of fatigue cracking on modified airplanes. We are proposing this AD to detect and correct fatigue cracking in the longitudinal lap joints of the fuselage lower lobe, which could lead to the rapid decompression of the airplane and the inability of the structure to carry fail-safe loads.
Airworthiness Directives; Airbus Model A300, A300-600, and A310 Airplanes
Document Number: 2010-3817
Type: Proposed Rule
Date: 2010-02-25

Type: Proposed Rule
Date: 2010-02-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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 a maintenance check performed by an A310 operator, the recommended modification of the lower attachment beam of rack 101VU by accomplishment of Airbus Service Bulletin (SB) A310-53-2076 was embodied on the aeroplane, leading the operator to find three cracks on the FR15A crossbeam above the NLG [nose landing gear] box at the splicing with rack 107VU fitting. This condition, if not detected and corrected, could degrade the structural integrity of the crossbeam on NLG FR15A web attachment fitting of rack 107VU. Rack 107VU contains major airworthiness system components whose functioning could be adversely affected by the loss of the attachment fitting. As the A300 and A300-600 aeroplanes share this design feature, they are also affected. The proposed AD would require actions that are intended to

Safety Zones; Annual Firework Displays Within the Captain of the Port, Puget Sound Area of Responsibility
Document Number: 2010-3812
Type: Proposed Rule
Date: 2010-02-25
Agency: Coast Guard, Department of Homeland Security
The Coast Guard proposes to establish multiple permanent safety zones to ensure public safety during annual firework displays at various locations the Captain of the Port, Puget Sound Area of Responsibility (AOR). When these safety zones are activated, and thus subject to enforcement, this rule would limit the movement of vessels within the established firework display areas. This action is necessary to prevent injury and to protect life and property of the maritime public from the hazards associated with firework displays. Entry into, transit through, mooring, or anchoring within these zones during times of enforcement is prohibited unless authorized by the Captain of the Port, Puget Sound or Designated Representative.
Endangered and Threatened Wildlife and Plants; Withdrawal of Proposed Rule To List the Southwestern Washington/Columbia River Distinct Population Segment of Coastal Cutthroat Trout (Oncorhynchus clarki clarki
Document Number: 2010-3803
Type: Proposed Rule
Date: 2010-02-25
Agency: Fish and Wildlife Service, Department of the Interior
We, the U.S. Fish and Wildlife Service (Service), have determined that the proposed listing of the Southwestern Washington/ Columbia River Distinct Population Segment (DPS) of coastal cutthroat trout as a threatened species under the Endangered Species Act of 1973, as amended (Act), is not warranted. We therefore withdraw our proposed rule (64 FR 16397; April 5, 1999) to list the DPS under the Act. Although we had earlier concluded that this DPS did not warrant listing under the Act, as a result of litigation we have reconsidered whether the marine and estuarine areas of the DPS may warrant listing if they constitute a significant portion of the range of the DPS. Based upon a thorough review of the best available scientific and commercial data, we have determined that the threats to coastal cutthroat trout in the marine and estuarine areas of its range within the DPS, as analyzed under the five listing factors described in section 4(a)(1) of the Act, are not likely to endanger the species now or in the foreseeable future throughout this portion of its range. We, therefore, again withdraw our proposed rule, as we have determined that the coastal cutthroat trout is not likely to become endangered now or in the foreseeable future throughout all or a significant portion of its range within the Southwestern Washington/Columbia River DPS.
Endangered and Threatened Wildlife and Plants; 12-Month Finding on a Petition To List the Sonoran Desert Population of the Bald Eagle as a Threatened or Endangered Distinct Population Segment
Document Number: 2010-3794
Type: Proposed Rule
Date: 2010-02-25
Agency: Fish and Wildlife Service, Department of the Interior
We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the Sonoran Desert Area population of the bald eagle (Haliaeetus leucocephalus) as a distinct population segment (DPS). In the petition, we were asked that the DPS be recognized, listed as endangered, and that critical habitat be designated under the Endangered Species Act of 1973, as amended (Act). After review of all available scientific and commercial information, we find that the Sonoran Desert Area population of the bald eagle does not meet the definition of a DPS and, therefore, is not a listable entity under the Act. As a result, listing is not warranted, and we intend to publish a separate notice to remove this population from the List of Threatened and Endangered Wildlife once the District Court for the District of Arizona has been notified. We ask the public to continue to submit to us any new information that becomes available concerning the taxonomy, biology, ecology, and status of this population of the bald eagle and to support cooperative conservation of the bald eagle within the Sonoran Desert Area.
