### 6017 Federal Register / Vol. 80, No. 23 / Wednesday, February 4, 2015 / Proposed Rules

1 A notation in the form of ‘‘Joint Comment, No. 43 at p. 1’’ identifies a written comment that DOE received and included in the docket of this rulemaking. This particular notation refers to a comment: (1) In the Joint Comment; (2) in the document number 43 of the docket; and (3) on page 1 of that document. The notice provided for the submission of written comments by December 22,

2014.

On December 22, 2014, DOE received a joint comment from the Appliance Standards Awareness Project (ASAP), Northwest Energy Efficiency Alliance (NEEA), the American Council for an Energy-Efficient Economy (ACEEE), and the Natural Resources Defense Council (NRDC) (Joint Comment). The full comment can be found in Docket No. EERE–2010–BT–STD–0043–43. The Joint Comment opposed DOE’s proposed determination for the following reasons:

1. Energy conservation standards for the [400 watt] metal halide representative lamp type are technically feasible and economically justified, and would result in significant energy savings (Joint Comment, No. 43 at p. 1); 1

2. DOE’s analysis fails to properly consider the likely consumer responses to replacing existing HID lamps (Joint Comment, No. 43 at p. 2); and

3. DOE’s analysis should be based on mean lumen output and not on initial lumen output (Joint Comment, No. 43 at p. 3).

DOE is reopening the public comment period for the October 21, 2014 NOPD to allow interested parties to provide DOE with comments and data in response to the points made in the Joint Comment. DOE will consider any comments in response to the Joint Comment received by midnight of March 6, 2015, and deems any comments received by that time to be timely submitted.

Issued in Washington, DC, on January 26,

2015. Kathleen B. Hogan, Deputy Assistant Secretary for Energy Efficiency, Energy Efficiency and Renewable Energy.

**Airworthiness Directives; Turbomeca S.A. Turboshaft Engines** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede airworthiness directive (AD) 2014–19– 05 that applies to all Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, 1S1, 2B, 2B1, 2C, 2C1, 2C2, 2S1, and 2S2 turboshaft engines. AD 2014–19–05 requires an initial one-time vibration check of the engine accessory gearbox (AGB) on certain higher risk Arriel 1 and Arriel 2 model engines and repetitive vibration checks for all Arriel 1 and Arriel 2 engines. Since we issued AD 2014–19– 05, we determined that a Technical Instruction (TI) number and a Test Bed Acceptance Test Specifications number in the Actions and Compliance and the Related Information sections are incorrect. This proposed AD would correct these numbers. We are proposing this AD to prevent failure ofthe engine AGB, which could lead to inflight shutdown and damage to the engine, which may result in damage to the aircraft.

Discussion

On September 15, 2014, we issued AD 2014–19–05, Amendment 39–17973 (79 FR 59091, October 1, 2014), for all Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, 1S1, 2B, 2B1, 2C, 2C1, 2C2, 2S1, and 2S2 turboshaft engines. AD 2014–19–05 requires an initial one-time vibration check of the engine AGB on certain higher risk Arriel 1 and Arriel 2 model engines. AD 2014–19–05 also requires repetitive vibration checks of the engine AGB for all Arriel 1 and Arriel 2 engines


### 6018 Federal Register / Vol. 80, No. 23 / Wednesday, February 4, 2015 / Proposed Rules

at every engine shop visit. AD 2014–19– 05 resulted from reports of uncommanded in-flight shutdowns on Turbomeca S.A. Arriel 1 and Arriel 2 engines, following rupture of the 41- tooth gear forming part of the 41/23- tooth bevel gear located in the engine AGB. We issued AD 2014–19–05 to prevent failure of the engine AGB, which could lead to in-flight shutdown and damage to the engine, which may result in damage to the aircraft.

Actions Since AD 2014–19–05 Was Issued

Since we issued AD 2014–19–05, Amendment 39–17973 (79 FR 59091, October 1, 2014), we determined that a TI number and a Test Bed Acceptance Test Specifications number in the Actions and Compliance and the Related Information sections are incorrect. This proposed AD would correct these numbers.

Relevant Service Information

We reviewed Turbomeca S.A. Mandatory Service Bulletin (MSB) No. 292 72 0839, Version B, dated November 25, 2013, and MSB No. 292 72 2849, Version B, dated November 25, 2013. The service information describes procedures for performing vibration checks of the engine AGB.

FAA’s Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements

This proposed AD would require an initial one-time vibration check of the engine AGB on certain higher risk Arriel 1 and Arriel 2 model engines. This AD also requires repetitive vibration checks of the engine AGB for all Arriel 1 and Arriel 2 engines at every engine shop visit. Costs of Compliance

We estimate that this proposed AD would affect 1,268 engines installed on aircraft of U.S. registry. We also estimate that it would take about 4 hours per engine to comply with the inspection requirement in this proposed AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $431,120. 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and

(4) 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. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2014–19–05, Amendment 39–17973 (79 FR 59091, October 1, 2014), and adding the following new AD:

Turbomeca S.A.: Docket No. FAA–2014– 0164; Directorate Identifier 2014–NE– 02–AD.

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve the Commonwealth of Pennsylvania’s request to redesignate to attainment the Allentown nonattainment area (Allentown Area or Area) for the 2006 24-hour fine particulate matter (PM 2.5 ) national ambient air quality standard (NAAQS). EPA is also proposing to determine that the Allentown Area continues to attain the 2006 24-hour PM 2.5 NAAQS. In addition, EPA is proposing to approve as a revision to the Pennsylvania State Implementation Plan (SIP) the associated maintenance plan to show maintenance of the 2006 24-hour PM 2.5 NAAQS through 2025 for the Area. The maintenance plan includes the 2017 and 2025 PM 2.5 and nitrogen oxides (NO
x ) mobile vehicle emissions budgets (MVEBs) for the Area for the 2006 24-hour PM 2.5 NAAQS, which EPA is proposing to approve for transportation conformity purposes. Finally, EPA is proposing to approve as a revision to the Pennsylvania SIP the 2007 base year emissions inventory for the Area for the 2006 24-hour PM 2.5 NAAQS. This rulemaking action to propose approval of the 2006 24-hour PM 2.5 NAAQS redesignation request and associated maintenance plan for the Allentown Area is based on EPA’s determination that Pennsylvania has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA) for the 2006 24-hour PM 2.5 NAAQS.
