NMFS issues this final rule to implement management measures for gray triggerfish described in Amendment 37 to the Fishery Management Plan for the Reef Fish Resources of the Gulf of Mexico (FMP), prepared by the Gulf of Mexico Fishery Management Council (Council). This final rule revises the commercial and recreational annual catch limits (ACLs) and annual catch targets (ACTs) for gray triggerfish; revises the recreational accountability measures (AMs) for gray triggerfish; revises the gray triggerfish recreational bag limit; establishes a commercial trip limit for gray triggerfish; and establishes a fixed closed season for the gray triggerfish commercial and recreational sectors. Additionally, Amendment 37 modifies the gray triggerfish rebuilding plan. The purpose of Amendment 37 and this final rule is to end overfishing of gray triggerfish and help achieve optimum yield (OY) for the gray triggerfish resource in accordance with the requirements of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act).
Significant New Use Rules on Certain Chemical Substances
EPA is promulgating significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 15 chemical substances which were the subject of premanufacture notices (PMNs). This action requires persons who intend to manufacture, import, or process any of these 15 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.
East Bay, St. Andrews Bay and the Gulf of Mexico at Tyndall Air Force Base, Florida; Restricted Areas
The U.S. Army Corps of Engineers (Corps) is proposing to amend its regulations by revising an existing restricted area regulation and establishing six new restricted areas along the Tyndall Air Force Base (AFB) facility shoreline. Tyndall AFB is surrounded on three sides by water with approximately 129 miles of unprotected coastline. This includes several areas where the lack of security or lack of restriction on access to these areas leaves Tyndall AFB personnel and resources vulnerable to unauthorized activities. This amendment is necessary to implement an enhanced security plan for Tyndall AFB, which includes four new permanent restricted areas and the ability to activate two additional restricted areas as local and national intelligence threat evaluations dictate.
Approval and Promulgation of Air Quality Implementation Plans; District of Columbia, Maryland and Virginia; Attainment Demonstration for the 1997 8-Hour Ozone National Ambient Air Quality Standard for the Washington, DC-MD-VA Moderate Nonattainment Area; Reopening of Comment Period
EPA is reopening the comment period for a notice published on March 20, 2013. In the March 20, 2013 notice of proposed rulemaking, EPA proposed to approve the attainment demonstration portion of the attainment plan for the Washington DC-MD-VA (Washington area) ozone nonattainment area submitted by the District of Columbia, the State of Maryland and the Commonwealth of Virginia as revisions to each of their State Implementation Plans (SIPs). At the request of the Maryland Department of the Environment (MDE), EPA is reopening the comment period. Comments submitted between the close of the original comment period and the re- opening of this comment period will be accepted and considered.
Duty Periods for Establishing Eligibility for Health Care
The Department of Veterans Affairs (VA) is proposing to amend its medical regulations concerning eligibility for health care to re- establish the definitions of ``active military, naval, or air service,'' ``active duty,'' and ``active duty for training.'' These definitions were deleted in 1996; however, we believe that all duty periods should be defined in part 17 of the Code of Federal Regulations (CFR) to ensure proper determination of eligibility for VA health care. We would also provide a more complete definition of ``inactive duty training.''
Pacific Ocean Off the Kekaha Range Facility at Barking Sands, Island of Kauai, Hawaii; Danger Zone
The Corps of Engineers is proposing to amend its regulations to establish a new danger zone in waters of the Pacific Ocean off the Kekaha Range Facility, Barking Sands, Island of Kauai, Hawaii. The proposed amendment is necessary for the Hawaii Army National Guard to continue small arms training operations at the Kekaha Range Facility and to protect the public from potentially hazardous conditions which may exist as a result of that use. The proposed amendment would prohibit, on an intermittent basis, vessels from entering a six mile wide section of the Pacific Ocean that narrows to a 0.7 mile wide section along the shoreline fronting the Kekaha Range Facility without first obtaining permission from the Commanding Officer of Kekaha Range Facility.
Horse Protection Act; Requiring Horse Industry Organizations To Assess and Enforce Minimum Penalties for Violations; Correction

We also announce the availability of a draft economic analysis (DEA) and draft environmental assessment of the proposed designation of critical habitat and an amended required determinations section of the proposal. We are reopening the comment period to allow all interested parties an opportunity to comment simultaneously on the revised proposed rule, the associated DEA and draft environmental assessment, and the amended required determinations section. Comments previously submitted need not be resubmitted, as they will be fully considered in preparation of the final rules.
General and Plastic Surgery Devices: Reclassification of Ultraviolet Lamps for Tanning, Henceforth To Be Known as Sunlamp Products
The Food and Drug Administration (FDA) is proposing to reclassify ultraviolet (UV) lamps intended to tan the skin from class I (general controls) exempt from premarket notification to class II (special controls) and subject to premarket notification, and to rename them sunlamp products. FDA is also designating special controls that are necessary to provide a reasonable assurance of the safety and effectiveness of the device. FDA is proposing this reclassification on its own initiative based on new information.
Special Regulations of the National Park Service, Curecanti National Recreation Area, Snowmobiles and Off-Road Motor Vehicles
The National Park Service proposes to amend its special regulations for Curecanti National Recreation Area, Colorado, to designate routes, water surfaces, and areas where snowmobiles or motor vehicles may be used off park roads. Unless authorized by special regulation, the operation of snowmobiles and the operation of motor vehicles off road within areas of the National Park System are prohibited. The other existing special regulations for Curecanti National Recreation Area would remain in effect.

The Coast Guard will enforce the Special Local Regulation for the annual National Maritime Week Tugboat Races in Elliott Bay, WA from 12 p.m. until 4:30 p.m. on May 11, 2013. This action is necessary to ensure the safety of all participants and spectators from the inherent dangers associated with these types of races which includes large wakes. During the enforcement period, no person or vessel may enter or remain in the regulated area except for participants in the event, supporting personnel, vessels registered with the event organizer, and personnel or vessels authorized by the Coast Guard Patrol Commander.
Safety Zone; High Water Conditions; Illinois River
The Coast Guard is establishing a temporary safety zone on the Illinois River from Mile Marker 187.2 to Mile Marker 285.9. This zone is intended to place restrictions on vessels due to current extreme high-water conditions. This safety zone is necessary to protect the general public, levee systems, vessels, and tows from the hazards associated with flood waters and potential catastrophic failure of the Marseilles Dam.
Version 5 Critical Infrastructure Protection Reliability Standards
This document contains corrections to the proposed rule (RM13- 5-000) which was published in the Federal Register of Wednesday, April 24, 2013 (78 FR 24107). The regulations proposed to approve certain reliability standards proposed by the North American Electric Reliability Corporation.
Approval and Promulgation of Implementation Plans; North Carolina; Control Techniques Guidelines and Reasonably Available Control Technology
EPA is approving several State Implementation Plan (SIP) revisions submitted to EPA by the State of North Carolina, through the North Carolina Department of Environment and Natural Resources (NC DENR), to address the nitrogen oxides (NOX) reasonably available control technology (RACT) requirements for the North Carolina portion of the Charlotte-Gastonia-Rock Hill, North CarolinaSouth Carolina 1997 8-hour ozone nonattainment area (hereafter referred to as the ``bi-state Charlotte Area''). The bi-state Charlotte Area for the 1997 8-hour ozone national ambient air quality standards (NAAQS) includes six full counties and one partial county in North Carolina; and one partial county in South Carolina. Additionally, EPA is approving in part, and conditionally approving in part, several SIP revisions to address the volatile organic compounds (VOC) RACT requirements which include related control technology guidelines (CTG) requirements. Together, these SIP revisions establish the RACT requirements for sources located in the North Carolina portion of the bi-state Charlotte Area. In a separate rulemaking, EPA has already taken action on RACT and CTG requirements for the South Carolina portion of the bi-state Charlotte Area. EPA has evaluated the revisions to North Carolina's SIP, and has made the determination that they are consistent, with the exception of applicability for some CTG VOC sources, with statutory and regulatory requirements and EPA guidance. With respect to the applicability provisions for the CTG VOC sources noted above, EPA is finalizing a conditional approval of these provisions.
Approval and Promulgation of Air Quality Implementation Plans; Alaska: Mendenhall Valley Nonattainment Area PM10 Limited Maintenance Plan and Redesignation Request
The EPA is taking direct final action to approve the Limited Maintenance Plan (LMP) for particulate matter with an aerodynamic diameter less than or equal to 10 micrometers (PM10) submitted by the State of Alaska on May 8, 2009, for the Mendenhall Valley nonattainment area (Mendenhall Valley NAA), and to concurrently redesignate the area to attainment for the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10).
Approval and Promulgation of Air Quality Implementation Plans; Alaska: Mendenhall Valley PM10 Nonattainment Area Limited Maintenance Plan and Redesignation Request
The EPA is proposing to approve the Limited Maintenance Plan (LMP) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10) submitted by the State of Alaska on May 8, 2009 for the Mendenhall Valley nonattainment area (Mendenhall Valley NAA), and the State's request to redesignate the area to attainment for the National Ambient Air Quality Standards (NAAQS).
Fisheries of the Northeastern United States; Atlantic Sea Scallop Fishery and Northeast Multispecies Fishery; Framework Adjustment 24 and Framework Adjustment 49
This action approves and implements Framework Adjustment 24 to the Atlantic Sea Scallop Fishery Management Plan (Framework 24) and Framework Adjustment 49 to the Northeast Multispecies Fishery Management Plan (Framework 49), which the New England Fishery Management Council (Council) adopted and submitted to NMFS for approval. Framework 24 sets specifications for the Atlantic sea scallop fishery for the 2013 fishing year, including days-at-sea allocations, individual fishing quotas, and sea scallop access area trip allocations. This action also sets default fishing year 2014 specifications, in case the New England Fishery Management Council delays the development of the next framework, resulting in implementation after the March 1, 2014, start of the 2014 fishing year, and transitional measures are needed. In addition, Framework 24 adjusts the Georges Bank scallop access area seasonal closure schedules, and because that changes exemptions to areas closed to fishing specified in the Northeast Multispecies Fishery Management Plan, Framework 24 must be a joint action with that plan (Framework 49). Framework 24 also continues the closures of the Delmarva and Elephant Trunk scallop access areas, refines the management of yellowtail flounder accountability measures in the scallop fishery, makes adjustments to the industry-funded observer program, and provides more flexibility in the management of the individual fishing quota program.
Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Prevention of Significant Deterioration
EPA is disapproving a narrow portion of a State Implementation Plan (SIP) revision submitted by the State of West Virginia on August 31, 2011. EPA is taking this final action because the submittal does not satisfy the Federal requirement for inclusion of condensable emissions of particulate matter (condensables) within the definition of ``regulated new source review (NSR) pollutant'' for fine particulate matter (PM2.5) and particulate matter emissions less than or equal to ten micrometers in diameter (PM10). In addition, because West Virginia's August 31, 2011 SIP revision does not adequately account for condensable emissions within the definition of ``regulated NSR pollutant,'' EPA is also disapproving specific Prevention of Significant Deterioration (PSD) portions of related infrastructure SIP submissions required by the Clean Air Act (CAA) to implement, maintain, and enforce the 1997 fine particulate matter (PM2.5) and ozone National Ambient Air Quality Standards (NAAQS), the 2006 PM2.5 NAAQS, and the 2008 lead and ozone NAAQS. This action is being taken under the CAA.
Approval and Promulgation of Implementation Plans; Utah; Revisions to Utah Rule R307-107; General Requirements; Breakdowns
EPA is proposing to approve changes to Utah's rule R307-107, which pertains to source emissions during breakdowns. On April 18, 2011, EPA finalized a rulemaking which found that the Utah State Implementation Plan (SIP) was substantially inadequate to attain or maintain the national ambient air quality standards (NAAQS) or to otherwise comply with the requirements of the Clean Air Act (CAA) because it included rule R307- 107. Concurrent with this finding, EPA issued a SIP call that required the State to revise its SIP by either removing R307-107 or correcting its deficiencies, and to submit the revised SIP to EPA by November 18, 2012. On August 16, 2012, the State submitted to EPA revisions to R307- 107. EPA is proposing that these revisions correct the rule's deficiencies and, therefore, satisfy EPA's April 18, 2011 SIP call. If EPA finalizes its proposed approval, all sanctions clocks and the clock for EPA to promulgate a federal implementation plan (FIP) will end.
Approval and Promulgation of Air Quality Implementation Plans; Connecticut; Ozone Attainment Demonstrations
EPA is proposing to approve the ozone attainment demonstrations (including the reasonably available control measures (RACM) analyses) submitted by Connecticut as a State Implementation Plan (SIP) revision on February 1, 2008 to meet Clean Air Act requirements for attaining the 1997 8-hour ozone national ambient air quality standard. EPA is proposing to approve Connecticut's demonstrations of attainment of the 1997 8-hour ozone standard for Connecticut's portion of the New York-Northern New Jersey-Long Island, NY-NJ-CT 1997 moderate ozone nonattainment area and for the Greater Connecticut moderate ozone nonattainment area. EPA is also proposing to approve the RACM analyses for these same areas.

Approval and Promulgation of Air Quality Implementation Plans; Louisiana; Approval of Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard for the Parish of Pointe Coupee
EPA is proposing to approve a revision to the Louisiana State Implementation Plan (SIP) concerning a maintenance plan addressing the 1997 8-hour ozone standard for the parish of Pointe Coupee. On February 28, 2007, the State of Louisiana submitted a SIP revision containing a maintenance plan for the 1997 ozone standard for Pointe Coupee Parish. This plan ensures the continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. On March 12, 2008, EPA issued a revised ozone standard. Today's action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for this area under the 2008 standard will be addressed in future actions. This maintenance plan meets statutory and regulatory requirements, and is consistent with EPA's guidance.
Approval and Promulgation of Air Quality Implementation Plans; Louisiana; Approval of Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard for the Parish of Pointe Coupee
EPA is granting direct final approval of a revision to the Louisiana State Implementation Plan (SIP) concerning a maintenance plan addressing the 1997 8-hour ozone standard for the parish of Pointe Coupee. On February 28, 2007, the State of Louisiana submitted a SIP revision containing a maintenance plan for the 1997 ozone standard for Pointe Coupee Parish. This plan ensures the continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. On March 12, 2008, EPA issued a revised ozone standard. Today's action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for this area under the 2008 standard will be addressed in future actions. This maintenance plan meets statutory and regulatory requirements, and is consistent with EPA's guidance.
Amendment of Class E Airspace; Kingston, NY
This action amends Class E Airspace at Kingston, NY, creating controlled airspace to accommodate new Standard Instrument Approach Procedures at Kingston-Ulster Airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport.
Modification of Class B Airspace; Philadelphia, PA
This action modifies the Philadelphia, PA, Class B airspace area to ensure the containment of large turbine-powered aircraft within Class B airspace, reduce controller workload, and reduce the potential for midair collision in the Philadelphia terminal area.
Modification of Class C Airspace; Nashville International Airport; TN
This action modifies the Nashville International Airport, TN, Class C airspace area by removing a cutout from the surface area that was put in place to accommodate operations at an airport that is now permanently closed. The FAA is taking this action to ensure the safe and efficient operations at Nashville International Airport.
Airworthiness Directives; Revo, Incorporated Airplanes
We are superseding an existing airworthiness directive (AD) for certain Revo, Incorporated Models COLONIAL C-1, COLONIAL C-2, LAKE LA-4, LAKE LA-4A, LAKE LA-4P, and LAKE LA-4-200 airplanes. That AD currently requires a one-time, dye-penetrant inspection of the horizontal stabilizer attachment fitting and repetitive visual inspections of the fitting for any evidence of fretting, cracking, or corrosion (with necessary replacement and modification); replacement of the fitting upon reaching the 850-hours time-in-service (TIS) safe life; and reporting to the FAA the results of the initial inspection and any cracks found on repetitive inspections. This new AD requires the same actions of AD 2005-12-02 except using revised service documents and procedures, adds Model COLONIAL C-1 airplanes to the Applicability, and adds an optional terminating action for the requirements. This AD was prompted by a report from Revo, Incorporated that, while the drawing numbers are different, the attachment fittings on the Model COLONIAL C-1 airplanes are identical in every other respect to those installed on the airplanes referenced in AD 2005-12- 02. We are issuing this AD to correct the unsafe condition on these products.
Agency Organization
The Commission is following up on a previous rulemaking by amending the description of its organizational functions in its regulations. It is also replacing its official seal. The changes to functional descriptions conform to expanded responsibilities under a postal reform law. Formal adoption of the new official seal also conforms to the postal reform law. Given the administrative nature of the changes, comments are not required or requested.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 and A330-300 series airplanes, and Model A340-200 and A340-300 series airplanes. This AD was prompted by reports of an elevator blocked in the down position due to two independent failures; first, the inability of a servo control to switch to active mode because it was not detected by a flight control computer; and second, an internal hydraulic leak due to the deterioration of an O-ring seal on a solenoid. This AD requires, depending on airplane configuration, modifying three flight control primary computers (FCPCs); modifying two flight control secondary computers (FCSCs); revising the airplane flight manual (AFM) to include certain information; replacing certain O-rings; and checking part number and replacing certain O-ring seals if needed. We are issuing this AD to detect and correct O-rings with incorrect part numbers whose deterioration could lead to improper sealing of solenoid valves; and to correct FCPC and FCSC software to allow better control of elevator positioning; both conditions, if not corrected, could lead to the loss of elevator control on takeoff, and potentially reduce the controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding two existing airworthiness directives (AD) that apply to certain The Boeing Company Model 737-100, -200, -200C, - 300, -400, and -500 series airplanes. Those ADs, for certain airplanes, currently require repetitive inspections of the flap track of the wing outboard flap, and corrective actions if necessary; and eventual rework of the flap track assembly and rear spar attachments. For certain airplanes, this new AD adds repetitive inspections, scheduled overhauls, correct alignment during installation, and repetitive maintenance of the flap track, and corrective actions if necessary. This new AD also adds airplanes to the applicability. This AD was prompted by reports that the work sequence and procedures used during installation of replacement tracks could cause loose or cracked tracks. We are issuing this AD to detect and correct cracking and damage in the flap track, which could cause loss of the outboard trailing edge flap and consequent reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 737-200, -200C, -300, -400, and - 500 series airplanes. That AD currently requires a one-time mid- frequency eddy current (MFEC) inspection, a low-frequency eddy current (LFEC) inspection, and a detailed inspection for damage or cracking of stringer S-4L and S-4R lap joints and stringer clips between body station (BS) 540 and BS 727, and follow-on inspections and repair if necessary. This new AD instead requires repetitive external eddy current inspections for cracking of certain fuselage crown lap joints, and corrective actions if necessary; internal eddy current and detailed inspections for cracking of certain fuselage crown lap joints, and repair if necessary; and detailed inspections of certain stringer clips, and replacement with new stringer clips if necessary. This AD also adds airplanes to the applicability. This AD was prompted by reports of cracking of the lap joint lower row. We are issuing this AD to detect and correct cracking of the fuselage lap joints, which could result in sudden decompression of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are revising an existing airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. That AD currently requires repetitive inspections to detect cracking in the web of the aft pressure bulkhead at body station 1016 at the aft fastener row attachment to the ``Y'' chord, various inspections for discrepancies at the aft pressure bulkhead, and related investigative and corrective actions if necessary. This new AD requires clarifying certain actions specified in the existing AD. This AD was prompted by several reports of fatigue cracks in the aft pressure bulkhead. We are issuing this AD to detect and correct such fatigue cracking, which could result in rapid decompression of the fuselage.
