Download as PDF Federal Register / Vol. 70, No. 180 / Monday, September 19, 2005 / Rules and Regulations After consideration of all relevant material presented, including the information and recommendation submitted by the Committee and other available information, it is hereby found that this rule, as hereinafter set forth, will tend to effectuate the declared policy of the Act. PART 922—APRICOTS GROWN IN DESIGNATED COUNTIES IN WASHINGTON Accordingly, the interim final rule amending 7 CFR part 922 which was published at 70 FR 36812 on June 27, 2005, is adopted as a final rule without change. I Dated: September 14, 2005. Lloyd C. Day, Administrator, Agricultural Marketing Service. [FR Doc. 05–18584 Filed 9–16–05; 8:45 am] BILLING CODE 3410–02–P DEPARTMENT OF ENERGY 10 CFR Part 300 RIN 1901–AB11 Guidelines for Voluntary Greenhouse Gas Reporting Office of Policy and International Affairs, U.S. Department of Energy. ACTION: Final rule; delay of effective date. AGENCY: SUMMARY: The Department of Energy (DOE) published interim final General Guidelines for its Voluntary Reporting of Greenhouse Gases Program on March 24, 2005 (70 FR 15169), and published in the same issue of the Federal Register a notice of availability inviting public comment on draft Technical Guidelines needed to fully implement the revised Voluntary Reporting of Greenhouse Gases Program (70 FR 15164). DOE today is delaying the effective date of the guidelines to address the comments received by DOE in response to the March 24, 2005 Federal Register notice and to align the effective date with the likely availability of final reporting forms being developed by the Energy Information Administration. DATES: The effective date of the rule establishing 10 CFR part 300 published in the Federal Register at 70 FR 15169 on March 24, 2005, is delayed until June 1, 2006. 15:27 Sep 16, 2005 Jkt 205001 Mark Friedrichs, PI–40, Office of Policy and International Affairs, U.S. Department of Energy, 1000 Independence Ave., SW., Washington, DC 20585, or e-mail: 1605bguidelines.comments@hq.doe.gov. As DOE explained in the notice of interim final rulemaking, the Technical Guidelines that supplement the General Guidelines will provide the specificity necessary for DOE to fully implement the greenhouse gas emissions inventory and emissions reduction elements of the voluntary reporting guidelines (70 FR 15171). DOE received a substantial number of written comments on the Interim Final General Guidelines and draft Technical Guidelines, and DOE expects to issue final General and Technical Guidelines by the end of 2005. At that time, the Energy Information Administration (EIA) will prepare reporting forms that conform to the Final General Guidelines and Final Technical Guidelines and begin developing the electronic reporting software necessary to implement the revised Program. Because DOE does not expect to issue final guidelines until the end of the calendar year, and because the Office of Management and Budget (OMB) clearance process under the Paperwork Reduction Act for EIA’s revised reporting forms will take at least 120 days following the issuance of the final guidelines, DOE is delaying the September 20, 2005 effective date of the rule published on March 24, 2005 until June 1, 2006. This delay in the effective date will allow EIA time to complete the development of revised reporting forms, including an opportunity for public review, after the final General and Technical Guidelines are issued at the end of 2005. Once EIA has completed the development of its planned electronic reporting system, approximately 9 to 12 months after the guidelines are finalized, reporting entities would be able to use it to report under the revised guidelines. Since it is unlikely that entities will be able to report under the revised guidelines by July 1, 2006, DOE will revise the General Guidelines to provide that entities may use DOE’s October 1994 guidelines for reporting in calendar year 2006. Entities that wish to report their emissions and reductions for 2005, or prior years, using the revised guidelines will be able to do so during the normal 2007 reporting cycle. Issued in Washington, DC, on September 13, 2005. Karen A. Harbert, Assistant Secretary, Policy and International Affairs.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CT7–5A2, –5A3, –7A, –7A1, –9B, –9B1, and –9B2 turboprop engines, with stage 2 turbine aft cooling plate, part number (P/N) 6064T07P01, 6064T07P02, 6064T07P05, or 6068T36P01 installed. This AD requires a onetime eddy current inspection (ECI) of certain P/N stage 2 turbine aft cooling plate boltholes. This AD results from reports of six stage 2 turbine aft cooling plates found cracked during inspection. We are issuing this AD to prevent stage 2 aft cooling plate separation, resulting in uncontained engine failure and damage to the airplane. This AD becomes effective October 24, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of October 24, 2005.

The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to GE CT7–5A2, –5A3, –7A, –7A1, –9B, –9B1, and –9B2 turboprop engines, with stage 2 turbine aft cooling plate, P/N 6064T07P01, 6064T07P02, 6064T07P05, or 6068T36P01 installed. We published the proposed AD in the Federal Register on April 15, 2005 (70 FR 19893). That action proposed to require a onetime ECI of certain P/N stage 2 turbine aft cooling plate boltholes. SUPPLEMENTARY INFORMATION: Examining the AD Docket You may examine the docket that contains the AD, any comments received, and any final disposition in person at the Docket Management Facility Docket Offices between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647–5227) is located on the plaza level of the Department of Transportation Nassif Building at the street address stated in ADDRESSES. Comments will be available in the AD docket shortly after the Document Management Facility receives them. Comments We provided the public the opportunity to participate in the development of this AD. We received no comments on the proposal or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are about 1,240 GE CT7–5, –7, and –9 series turboprop engines of the affected design in the worldwide fleet. We estimate that 550 engines installed on airplanes of U.S. registry will be affected by this AD. We also estimate that it would take about one work hour per engine to perform the actions, and that the average labor rate is $65 per work hour. We estimate that 2.5% (or 14) of the 550 engines will require stage 2 turbine aft cooling plates being rejected by the onetime ECI. Required parts will cost about $17,000 per engine. Based on these figures, we estimate the total cost of the AD to U.S. operators to be $270,700. VerDate Aug<31>2005 15:27 Sep 16, 2005 Jkt 205001 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under ADDRESSES.

SUPPLEMENTARY INFORMATION: Background The Rule This action amends Title 14 Code of Federal Regulations (14 CFR part 71) by establishing V–19 in the Cincinnati, OH, area. Specifically, this action establishes V–19 between Columbus, OH, and Cincinnati, OH, to the south of V–5 and to the north of the Buckeye Military Operations Area. The FAA is taking this action to reduce congestion on V–5 and to enhance the management of aircraft operations over the Cincinnati, OH, area. The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is Frm 00005 certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; General Electric Company CT7-5, -7, and 
-9 Series Turboprop Engines

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
General Electric Company (GE) CT7-5A2, -5A3, -7A, -7A1, -9B, -9B1, and 
-9B2 turboprop engines, with stage 2 turbine aft cooling plate, part 
number (P/N) 6064T07P01, 6064T07P02, 6064T07P05, or 6068T36P01 
installed. This AD requires a onetime eddy current inspection (ECI) of 
certain P/N stage 2 turbine aft cooling plate boltholes. This AD 
results from reports of six stage 2 turbine aft cooling plates found 
cracked during inspection. We are issuing this AD to prevent stage 2 
aft cooling plate separation, resulting in uncontained engine failure 
and damage to the airplane.

DATES: This AD becomes effective October 24, 2005. The Director of the 
Federal Register approved the incorporation by reference of certain 
publications listed in the regulations as of October 24, 2005.

ADDRESSES: You can get the service information identified in this AD 
from General Electric Aircraft Engines CT7 Series Turboprop Engines,

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to GE CT7-5A2, -5A3, -7A, -
7A1, -9B, -9B1, and -9B2 turboprop engines, with stage 2 turbine aft 
cooling plate, P/N 6064T07P01, 6064T07P02, 6064T07P05, or 6068T36P01 
installed. We published the proposed AD in the Federal Register on 
April 15, 2005 (70 FR 19893). That action proposed to require a onetime 
ECI of certain P/N stage 2 turbine aft cooling plate boltholes.

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the Docket Management 
Facility Docket Offices between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The Docket Office (telephone (800) 
647-5227) is located on the plaza level of the Department of 
Transportation Nassif Building at the street address stated in 
ADDRESSES. Comments will be available in the AD docket shortly after 
the Document Management Facility receives them.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the proposal or on 
the determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

    There are about 1,240 GE CT7-5, -7, and -9 series turboprop engines 
of the affected design in the worldwide fleet. We estimate that 550 
engines installed on airplanes of U.S. registry will be affected by 
this AD. We also estimate that it would take about one work hour per 
engine to perform the actions, and that the average labor rate is $65 
per work hour. We estimate that 2.5% (or 14) of the 550 engines will 
require stage 2 turbine aft cooling plates being rejected by the 
onetime ECI. Required parts will cost about $17,000 per engine. Based 
on these figures, we estimate the total cost of the AD to U.S. 
operators to be $270,700.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
subtitle VII, part A, subpart III, section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.
