EPA is proposing to partially approve and partially disapprove State Implementation Plan (SIP) revisions submitted by the Governor of Utah on February 22, 1999. These revisions updated the State of Utah's maintenance plan for the 1-hour ozone standard for Salt Lake County and Davis County. As part of this action, EPA is also addressing certain actions it took in 2003 concerning such maintenance plan. This action is being taken under section 110 of the Clean Air Act (CAA).

This action proposes to amend Class E Airspace in the Tallahassee, FL area. Tallahassee Commercial Airport has been abandoned and controlled airspace is no longer needed. Airspace reconfiguration is necessary for the continued safety and management of instrument flight rules (IFR) operations within the Tallahassee, FL airspace area.

This action proposes to establish Class E airspace at Eureka, NV. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Eureka Airport, Eureka, NV. The FAA is proposing this action to enhance the safety and management of aircraft operations at the airport.

The Coast Guard is establishing a permanent regulated navigation area (RNA) on a portion of Elliott Bay in Seattle, Washington. The RNA will protect the seabed in portions of the bay that are subject to the U.S. Environmental Protection Agency (EPA)'s Pacific Sound Resources (PSR) and Lockheed Shipyard superfund cleanup remediation efforts. This RNA will prohibit activities that would disturb the seabed, such as anchoring, dragging, trawling, spudding or other activities that involve disrupting the integrity of the sediment caps that cover the superfund sites. It will not affect transit or navigation of the area.

The Coast Guard is establishing a temporary safety zone on the waters of Biscayne Bay in Miami, Florida during the Volvo Ocean Racing Youth Regatta. The event is scheduled to take place on Saturday, May 12, 2012 and Sunday, May 13, 2012. The safety zone is necessary for the safety of race participants and the general public during the event. Persons and vessels are prohibited from entering, transiting through, anchoring in, or remaining within the safety zone unless authorized by the Captain of the Port Miami or a designated representative.

The Coast Guard is establishing a temporary security zone on the waters of Port Everglades in Fort Lauderdale, Florida during 2012 Fleet Week. 2012 Fleet Week will take place from Wednesday, April 25, 2012 through Monday, April 30, 2012. The security zone will encompass the main shipping channel into Port Everglades Harbor and the Intracoastal Waterway through Port Everglades Harbor. The security zone will be enforced while U.S. Navy vessels participating in 2012 Fleet Week transit into and out of Port Everglades. The security zone is necessary to ensure the safety and security of U.S. Navy vessels, the public, and surrounding waterway from terrorist acts, sabotage or other subversive acts, accidents, or other causes of a similar nature. Entering or remaining in this security zone is prohibited unless authorized by the Captain of the Port Miami or a designated representative.

This rule revises the quantity of Class 1 (Scotch) spearmint oil that handlers may purchase from, or handle on behalf of, producers during the 2011-2012 marketing year. This rule increases the Scotch spearmint oil salable quantity from 733,913 pounds to 876,596 pounds, and the allotment percentage from 36 percent to 43 percent. The marketing order regulates the handling of spearmint oil produced in the Far West and is administered locally by the Spearmint Oil Administrative Committee (Committee). The Committee unanimously recommended this rule for the purpose of avoiding extreme fluctuations in supplies and prices and to help maintain stability in the Far West spearmint oil market.

We are superseding an existing airworthiness directive (AD) for all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747- 200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. That AD currently requires an inspection of the No. 2 and No. 3 windows on the left and right sides of the airplane to determine their part numbers, related investigative and corrective actions if necessary, and repetitive inspections of single pane windows. This new AD requires installing dual pane No. 2 and No. 3 windows. This new AD also removes certain airplanes from the applicability. This AD was prompted by loss of a No. 3 window in flight, which could result in consequent rapid loss of cabin pressure. Loss of the window could also result in crew communication difficulties or incapacitation of the crew. We are issuing this AD to correct the unsafe condition on these products.

EPA is approving Section 1.11 of Colorado's procedural rules as adopted by the Air Quality Control Commission (Commission) on January 16, 1998 and submitted to EPA as a State Implementation Plan (SIP) revision on November 5, 1999. Section 1.11.0 provides for specific requirements regarding the composition of the Commission and disclosure by its members of potential conflicts of interest. We are also approving the remaining portion of Colorado's January 7, 2008 submittal to meet the Infrastructure requirements of section 110(a)(2) of the Clean Air Act (CAA) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS), specifically the portion intended to address the requirements of section 110(a)(2)(E)(ii) of the CAA. The proposed approval appeared in the Federal Register on January 4, 2012 (77 FR 235). EPA has determined that the approved revisions in Colorado's submittals are consistent with the CAA. This action is being taken under section 110 of the Clean Air Act.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 747 airplanes. This AD was prompted by reports of fractured latch pins found in service; investigation revealed that the cracking and subsequent fracture were initiated by fatigue and propagated by a combination of fatigue and stress corrosion. This AD requires repetitive general visual inspections for broken or missing latch pins of the lower sills of the forward and aft lower lobe cargo doors; repetitive detailed inspections for cracking of the latch pins; and corrective actions if necessary. We are issuing this AD to detect and correct fractured or broken latch pins, which could result in a forward or aft lower lobe cargo door opening and detaching during flight, and consequent rapid decompression of the airplane.

We are superseding an existing airworthiness directive (AD) for certain Airbus Model A310 series airplanes. That AD currently requires, for certain airplanes, modifying the wire routing and installing additional protective sleeves. This new AD adds, for certain airplanes, modifying wire routings and installing a modified bracket. This AD was prompted by analyses of the wire routing showing that the route of the fuel electrical circuit in the right-hand wing must be modified in order to ensure better segregation between fuel quantity indication wires and the 115-volt alternating current wires. We are issuing this AD to prevent short circuits leading to arcing, and possible fuel tank explosion.

We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This AD was prompted by the discovery of tail rotor blade assemblies (blades) manufactured with mislocated aluminum wire mesh, leaving portions of the graphite torque tube (spar) region unprotected from a lightning strike. The actions are intended to detect mislocated blade wire mesh and to prevent spar delamination, loss of the blade tip cap during a lightning strike, blade imbalance, loss of a blade, and subsequent loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Models DG-500 Elan Orion, DG-500 Elan Trainer, DG-500/ 20 Elan, and DG-500/22 Elan sailplanes and Models DG-500M and DG-500MB powered sailplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 incorrect re-installation of the rear cockpit securing rope for the headrest of the rear seat during maintenance, which could cause the rear seat to interfere with the control stick of the sailplane. We are issuing this AD to require actions to address the unsafe condition on these products.
