could affect safe operation of the Learjet Model 35, 35A, 36, and 36A airplanes, are addressed, and (2) appropriate Instructions for Continued Airworthiness, which include maintenance requirements, are established to ensure the availability of electrical power, when needed, from the batteries.

In lieu of the requirements of 14 CFR 25.1353(b)(1) through (b)(4) at Amendment 25–113, the following special conditions apply. Rechargeable lithium-ion batteries and battery systems on Learjet Model 35, 35A, 36, and 36A airplanes must be designed and installed as follows:

1. Safe cell temperatures and pressures must be maintained during any foreseeable charging or discharging condition, and during any failure of the charging or battery monitoring system not shown to be extremely remote. The rechargeable lithium-ion batteries and battery systems must preclude explosion in the event of those failures.

2. Design of the rechargeable lithiumion batteries and battery systems mustpreclude the occurrence of selfsustaining, uncontrolled increases in temperature or pressure.

3. No explosive or toxic gases emitted by any rechargeable lithium-ion batteries and battery systems in normal operation, or as the result of any failure of the battery charging system, monitoring system, or battery installation that is not shown to be extremely remote, may accumulate in hazardous quantities within the airplane.

4. Installations of rechargeable lithium-ion batteries and battery systems must meet the requirements of § 25.863(a) through (d).

5. No corrosive fluids or gases that may escape from any lithium-ion batteries and battery systems may damage surrounding structure or any adjacent systems, equipment, or electrical wiring of the airplane in such a way as to cause a major or more severe failure condition, in accordance with § 25.1309 (b) and applicable regulatory guidance.

6. Each lithium-ion battery and battery system must have provisions to prevent any hazardous effect on structure or essential systems caused by the maximum amount of heat the battery can generate during a short circuit of the battery or of its individual cells.

7. Rechargeable lithium-ion batteries and battery systems must have a system to automatically control the charging rate of the battery, so as to prevent battery overheating or overcharging, and: i. A battery-temperature sensing and over-temperature warning system with a means for automatically disconnecting the battery from its charging source in the event of an over-temperature condition, or,

ii. A battery-failure sensing and warning system with a means for automatically disconnecting the battery from its charging source in the event of battery failure.

8. Any rechargeable lithium-ion batteries and battery systems, the function of which are required for safe operation of the airplane, must incorporate a monitoring and warning feature that will provide an indication to the appropriate flight crewmembers whenever the state-of-charge of the batteries has fallen below levels considered acceptable for dispatch of the airplane.

9. The Instructions for Continued Airworthiness required by § 25.1529 must contain maintenance requirements to assure that the lithium-ion batteries are sufficiently charged at appropriate intervals specified by the battery manufacturer and the equipment manufacturer of the rechargeable lithium-ion battery or rechargeable lithium-ion battery system. This is required to ensure that rechargeable lithium-ion batteries and battery systems will not degrade below specified ampere-hour levels sufficient to power the aircraft system, for intended applications. The Instructions for Continued Airworthiness must also contain procedures for the maintenance of batteries in spares storage to prevent the replacement of batteries with batteries that have experienced degraded charge-retention ability or other damage due to prolonged storage at a low state of charge. Replacement batteries must be of the same manufacturer and part number as approved by the FAA. Precautions should be included in the Instructions for Continued Airworthiness maintenance instructions to prevent mishandling of the rechargeable lithium-ion batteries and batterysystems, which could result in shortcircuit or other unintentional impact damage caused by dropping or other destructive means.

Note 1: The term ‘‘sufficiently charged’’’ means that the battery will retain enough of a charge, expressed in ampere-hours, to ensure that the battery cells will not be damaged. A battery cell may be damaged by lowering the charge below a point where the battery experiences a reduction in the ability to charge and retain a full charge. This reduction would be greater than the reduction that may result from normal operational degradation. Note 2: These special conditions are not intended to replace § 25.1353(b) at Amendment 25–113 in the certification basis for Learjet Model 35, 35A, 36, and 36A airplanes. These special conditions apply only to rechargeable lithium-ion batteries and battery systems and their installations. The requirements of § 25.1353(b) at Amendment 25–113 remain in effect for batteries and battery installations on Learjet Model 35, 35A, 36, and 36A airplanes that do not use rechargeable lithium-ion batteries.

**SUMMARY :**  The Environmental Protection Agency (EPA) is approving the Lead 2010 base year emissions inventory State Implementation Plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC) on April 11, 2013. The emissions inventory was submitted to meet the requirements of the Clean Air Act (CAA or Act) for the Bristol 2008 Lead National Ambient Air Quality Standards (NAAQS) nonattainment area (hereafter also referred to as the ‘‘Bristol Area’’ or ‘‘Area’’). Additionally, EPA is converting conditional approvals to full approvals for Tennessee’s 1997 annual fine particulate matter (PM2.5 ) NAAQS, 2006 24-hour PM 2.5 NAAQS and 2008 8- hour ozone NAAQS infrastructure SIPs as they relate to adequate provisions prohibiting emissions that interfere with any other State’s required measures to prevent significant deterioration of its air quality. EPA conditionally approved these portions of Tennessee’s infrastructure SIPs for these NAAQS on March 6, 2013, and March 26, 2013. Tennessee has since met the obligations

**SUPPLEMENTARY INFORMATION :**  I. Background II. This Action III. Final Action IV. Statutory and Executive Order Reviews I. Background
a. Emissions Inventory

States are required under section 172(c)(3) of the CAA to develop comprehensive, accurate and current emissions inventories of all sources of the relevant pollutant or pollutants in the area. These inventories provide a detailed accounting of all emissions and emission sources by precursor or pollutant. In the November 12, 2008 Lead Standard rulemaking, EPA finalized the guidance related to the emissions inventories requirements. The current regulations are located at 40 CFR 51.117(e), and include, but are not limited to, the following requirements:

• States must develop and periodically update a comprehensive, accurate, current inventory of actual emissions from all source affecting ambient lead concentrations;

• The SIP inventory must be approved by EPA as a SIP element and is subject to public hearing requirements; and

• The point source inventory upon which the summary of the baseline for lead emissions inventory is based must contain all sources that emit 0.5 or more tons of lead per year.

For the base-year inventory of actual emissions, EPA recommends using either 2010 or 2011 as the base year for the contingency measure calculations, but does provide flexibility for using other inventory years if states can show another year is more appropriate. 1 For lead SIPs, the CAA requires that all sources of lead emissions in the nonattainment area must be submitted with the base-year inventory. In today’s action, EPA is approving the base year emissions inventory portion of the SIP revision submitted by Tennessee on April 11, 2013, as required by section 172(c)(3). On October 23, 2013, EPA proposed approval of Tennessee’s April 11, 2013, SIP revision. See 78 FR 63148. EPA did not receive any comments, adverse or otherwise, on the October 23, 2013, proposed action. b. Conditional Approvals

On October 4, 2012, Tennessee submitted a letter requesting conditional approval of certain prevention of significant deterioration (PSD)-related infrastructure elements. 2 Specifically, Tennessee requested conditional approval of elements of the infrastructure SIP related to the requirements in its SIP applicable to its permitting program for adopting the PM 2.5 PSD increments as promulgated in the rule entitled ‘‘Prevention of Significant Deterioration (PSD) for Particulate Matter Less Than 2.5 Micrometers (PM 2.5 )—Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC), Final Rule,’’ 75 FR 64864 (October 20, 2010) (hereafter referred to as the ‘‘PM 2.5 PSD Increments-SILs-SMC Rule’’). Following promulgation of the PM2.5 PSD Increment-SILs-SMC Rule, the PSD increments portion of the Rule became one of the prerequisites for approval of the PSD-related infrastructure requirements of sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 1997 annual and 2006 24-hour PM 2.5 NAAQS and the 2008 8-hour ozone NAAQS. The Rule provides additional regulatory provisions under the PSD program regarding the implementation of the PM 2.5 NAAQS for New Source Review, including PM 2.5 increments pursuant to section 166(a) of the CAA to prevent significant deterioration of air quality in areas meeting the NAAQS. PSD increments prevent air quality in attainment/unclassifiable areas from deteriorating to the level set by the NAAQS. As such, an increment is the mechanism used to estimate ‘‘significant deterioration’’ of air quality for a pollutant in an area. Under section 165(a)(3) of the CAA, a PSD permit applicant must demonstrate that emissions from the proposed construction and operation of a facility ‘‘will not cause, or contribute to, air pollution in excess of any maximum allowable increase or allowable concentration for any pollutant.’’

With respect to the PSD-related requirements of section 110(a)(2)(D)(i)(II) for the 1997 annual and 2006 24-hour PM2.5 NAAQS, and sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 2008 8-hour ozone NAAQS, EPA conditionally approved Tennessee’s infrastructure SIP submissions, because at the time of these approvals, the State had not yet adopted the PSD increments provided in the PM 2.5 PSD Increments-SILs-SMC Rule; however, the State had committed through the October 4, 2012, commitment letter to do so within one year. Based upon this commitment, and consistent with section 110(k)(4) of the CAA, EPA took final action to conditionally approval the portions of Tennessee’s infrastructure SIPsubmissions related to the abovedescribed PSD program requirements for the PM 2.5 1997 annual and the 2006 24- hour NAAQS, and the 2008 8-hour ozone NAAQS. See 78 FR 14450 (March 6, 2013) and 78 FR 18241 (March 26, 2013), respectively.

Following these actions, and consistent with the terms of the conditional approvals, Tennessee submitted a SIP revision on May 10, 2013, to adopt the PSD PM2.5 increments (set forth in Chapter 1200–03–09 of the Tennessee Air Pollution Control Regulations— Construction and Operating Permits, Rule Number .01— Construction Permits) and the then


### 1595 Federal Register / Vol. 79, No. 6 / Thursday, January 9, 2014 / Rules and Regulations

applicable regulatory requirements for implementing the PM 2.5 NAAQS, as promulgated in the PM 2.5 PSD Increments-SILs-SMC Rule. This SIP revision was provided to satisfy the October 4, 2012, commitment made by the State. On July 25, 2013, EPA took final action approving the May 10, 2013, submittal. See 78 FR 44886. As such, Tennessee has satisfied the conditions listed in EPA’s previous conditional approvals for these infrastructure submissions. See 78 FR 44886 for additional information.

II. This Action

On October 23, 2013 (78 FR 63148), EPA proposed approval of Tennessee’s April 11, 2013, submission regarding the Bristol, Tennessee Lead 2010 base year emissions inventory and proposed to convert to full approvals the existing conditional approvals of Tennessee’s 1997 annual PM2.5 NAAQS, 2006 24- hour PM 2.5 NAAQS and 2008 8-hour ozone NAAQS infrastructure SIPs as they relate to adequate provisions prohibiting emissions that interfere with any other state’s required measures to prevent significant deterioration of its air quality. EPA received no adverse comments on its proposed action and is hereby finalizing approval of this action.

III. Final Action

EPA is approving the 2010 base year emissions inventory SIP revision for lead for the Bristol Area as submitted by the State of Tennessee on April 11, 2013. Additionally, EPA is converting to full approvals the March 6, 2013, and March 26, 2013, conditional approvals of the PSD-related requirements of section 110(a)(2)(D)(i)(II) for the 1997 annual and the 2006 24-hour PM2.5 NAAQS, and the PSD-related requirements of sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 2008 8-hour ozone. EPA is also removing the conditional approval language from 40 CFR 52.2219 to reflect that these elements of the infrastructure SIPs have been converted to full approval, and that Tennessee has met the State’s obligations related to the previous conditional approvals. These actions are being taken pursuant to section 110 of the CAA. IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

• Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq. );

• does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4);

• does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and

• does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this action does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register . A major rule cannot take effect until 60 days after it is published in the Federal Register

. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by March 10, 2014. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).

I. Background
a. General Background

Section 110 of the CAA requires states to develop and submit to EPA a SIP to ensure that state air quality meets the National Ambient Air Quality Standards (NAAQS). These ambient standards currently address six criteria pollutants: Carbon monoxide, nitrogen dioxide, ozone, lead, particulate matter, and sulfur dioxide. The SIP protects air quality primarily by addressing air pollution at its point of origin; it is a set of air pollution regulations, control strategies, other means or techniques, and technical analyses developed by the state, to ensure that the state meets the NAAQS. When a state makes changes to the regulations and control strategies in its SIP, such revision(s) must be submitted to EPA for approval andincorporation into the federallyenforceable SIP. Such regulations and control strategies within the SIP must be specific, permanent, enforceable, and quantifiable.

The SIP under revision in this rulemaking addresses ozone. Ground level ozone is created by a chemical reaction between nitrogen oxides (NO X) and volatile organic compounds (VOCs) in the presence of sunlight and high ambient temperatures. 1 Motor vehicle exhaust and industrial emissions,
