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 must 

preclude 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 battery 

systems, 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.

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

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 PM2.5 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 

PM2.5 PSD increments as promulgated in 

the rule entitled ‘‘Prevention of 

Significant Deterioration (PSD) for 

Particulate Matter Less Than 2.5 

Micrometers (PM2.5)—Increments, 

Significant Impact Levels (SILs) and 

Significant Monitoring Concentration 

(SMC), Final Rule,’’ 75 FR 64864 

(October 20, 2010) (hereafter referred to 

as the ‘‘PM2.5 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 PM2.5 NAAQS and the 

2008 8-hour ozone NAAQS. The Rule 

provides additional regulatory 

provisions under the PSD program 

regarding the implementation of the 

PM2.5 NAAQS for New Source Review, 

including PM2.5 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 PM2.5 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 SIP 

submissions related to the abovedescribed PSD program requirements for 

the PM2.5 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 


PMANGRUM on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 79, No. 6 / Thursday, January 9, 2014 / Rules and Regulations 1595 

applicable regulatory requirements for 

implementing the PM2.5 NAAQS, as 

promulgated in the PM2.5 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 PM2.5 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 and 

incorporation 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 (NOX) 

and volatile organic compounds (VOCs) 

in the presence of sunlight and high 

ambient temperatures.1 Motor vehicle
