Approval and Promulgation of Implementation Plans; Tennessee; 
Bristol; 2010 Lead Base Year Emissions Inventory and Conversion of 
Conditional Approvals for Prevention of Significant Deterioration

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve 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 proposing to convert 
conditional approvals to full approvals for Tennessee's 1997 annual 
fine particulate matter (PM2.5) NAAQS, 2006 24-hour 
PM2.5 NAAQS and 2008 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 submissions for these NAAQS on 
March 6, 2013, and March 26, 2013. Tennessee has since met the 
obligations associated with these conditional approvals, and therefore, 
EPA is proposing to convert these conditional approvals to full 
approvals.

I. Background

a. Emissions Inventory

    On November 12, 2008 (73 FR 66964), EPA revised the Lead NAAQS, 
lowering the level from 1.5 micrograms per cubic meter ([micro]g/m\3\) 
to 0.15 [micro]g/m\3\ calculated over a three-month rolling average. 
EPA established the NAAQS based on significant evidence and numerous 
health studies demonstrating that serious health effects are associated 
with exposures to lead emissions.
    Following promulgation of a new or revised NAAQS, EPA is required 
by the CAA to designate areas throughout the United States as attaining 
or not attaining the NAAQS; this designation process is described in 
section 107(d)(1) of the CAA. On November 22, 2010 (75 FR 71033), EPA 
promulgated initial air quality designations for the 2008 Lead NAAQS, 
which became effective on December 31, 2010, based on air quality 
monitoring data for calendar years 2007-2009, where there was 
sufficient data to support a nonattainment designation. Designations 
for all remaining areas were completed on November 22, 2011 (76 FR 
72097), which became effective on December 31, 2011, based on air 
quality monitoring data for calendar years 2008-2010. Effective 
December 31, 2010, the Bristol Area was designated as nonattainment for 
the 2008 Lead NAAQS. This designation triggered a requirement for 
Tennessee to submit a SIP revision with a plan for how the Bristol Area 
would attain the 2008 Lead NAAQS as expeditiously as practicable, but 
no later than December 31, 2015.
    Designation of an area as nonattainment starts the process for a 
state to develop and submit to EPA a SIP revision under title I, part D 
of the CAA. This SIP revision must include, among other elements, a 
demonstration of how the NAAQS will be attained in the nonattainment 
area as expeditiously as practicable, but no later than the date 
required by the CAA, together with a base year emissions inventory, 
reasonably available control measures (RACM), a reasonable further 
progress (RFP) plan, contingency measures for failure to meet RFP and 
attainment deadlines. Under CAA section 172(b), a state has up to three 
years after an area's designation as nonattainment to submit its SIP 
revision to EPA.
    On August 29, 2012 (77 FR 55232), EPA took final action to 
determine that the Bristol Area (comprising the portion of Sullivan 
County bounded by a 1.25 kilometer radius surrounding the Universal 
Transverse Mercator coordinates 4042923 meters E, 386267 meters N, Zone 
17, which surrounds the Exide Technologies Facility, the only source 
above the revised lead NAAQS within the Area) had attaining data for 
the 2008 Lead NAAQS. This clean data determination was based upon 
quality assured, quality controlled and certified ambient air 
monitoring data that shows the Area has monitored attainment of the 
2008 Lead NAAQS based on the calendar years 2009-2011 data. The 2012 
monitoring data also demonstrated attainment for the 2008 Lead NAAQS. 
Pursuant to EPA's Clean Data Policy, once EPA finalizes a clean data 
determination, all the requirements for the Area to submit an 
attainment demonstration, RACM, a RFP plan, and contingency measures 
for failure to meet RFP and attainment deadlines are suspended for so 
long as the Area continues to attain the 2008 Lead NAAQS.
    Since 1995, EPA has applied its interpretation under the Clean Data 
Policy in many rulemakings, suspending certain attainment-related 
planning requirements for individual areas, based on a determination of 
attainment. EPA notes that a final determination of attainment would 
not suspend the emissions inventory requirement found in CAA section 
172(c)(3), which requires submission and approval of a comprehensive, 
accurate, and current inventory of actual emissions of the lead from 
all sources in the nonattainment area (i.e., base year emissions 
inventory).

b. Conditional Approvals

    On October 4, 2012, Tennessee submitted a letter requesting 
conditional approval of certain prevention of significant deterioration 
(PSD)-related infrastructure elements.\1\ Specifically,

[[Page 63150]]

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 2008 ozone NAAQS, and the 
1997 annual and 2006 24-hour PM2.5 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. 
Therefore, 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.''
---------------------------------------------------------------------------

    \1\ The CAA requires that the SIP provide for the 
implementation, maintenance, and enforcement of each NAAQS 
promulgated by EPA, which is commonly referred to as an 
``infrastructure'' SIP. See 42 U.S.C. 7410(a).
---------------------------------------------------------------------------

    With respect to the PSD requirements of sections 110(a)(2)(C), 
110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 2008 ozone NAAQS, and 
110(a)(2)(D)(i)(II) for the 1997 annual and 2006 24-hour 
PM2.5 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 Increment-SILs-SMC Rule; however, the State had 
committed through the October 4, 2012, 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 Tennessee's 
infrastructure SIP submissions related to the above-described PSD 
program requirements for the 1997 annual and the 2006 24-hour fine 
PM2.5 NAAQS, and the 2008 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 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. 
EPA took final action approving the May 10, 2013, submittal on July 25, 
2013. See 78 FR 44886. As such, Tennessee has satisfied the conditions 
listed in EPA's previous conditional approvals for these infrastructure 
submissions. (See the above July 25, 2013, Federal Register publication 
for additional information).

II. Emissions Inventory Requirements

    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 (PDF) (99pp, 665k) 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.\2\ 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, 
(hereinafter also referred to as ``Tennessee's submission'') as 
required by section 172(c)(3).
---------------------------------------------------------------------------

    \2\ See EPA document titled ``Addendum to the 2008 Lead NAAQS 
Implementation Questions and Answers'' dated August 10, 2012, 
included in EPA's SIP Toolkit located at http://www.epa.gov/air/lead/kitmodel.html.
---------------------------------------------------------------------------

III. EPA Analysis of the Bristol 2010 Lead Base Year Emissions 
Inventory

    The State of Tennessee followed EPA's recommendation by using the 
year of designation (2010) as the base year in the Bristol Area. Actual 
emissions from all sources of lead were reviewed and compiled, as 
applicable and available, for the base year emissions inventory 
requirement. The discussion below provides more details on how the lead 
emissions were calculated for the Bristol Area.
    The only source of lead emissions above 0.5 tons per year within 
the Bristol Area is Exide Technologies Facility, a lead acid battery 
manufacturing and recycling facility which processes lead and reclaimed 
lead into batteries for the auto industry. Pursuant to 40 CFR 
51.117(e), the Exide Technologies Facility is the only point source 
evaluated as part of this emissions inventory requirement. The 
stationary point source emissions for the Exide Technologies Facility 
were calculated using data collected through stack tests and the 
application of AP-42 emissions factors for the source and quality 
assured by TDEC (see Appendix A of Tennessee's submission). To obtain 
estimates of the stationary area and nonroad and onroad mobile 
emissions, Tennessee used the EPA 2008 National Emissions Inventory 
(NEI) \3\ for Sullivan County, as the Bristol Area is located within 
Sullivan County. Specifically, area source emissions were obtained from 
the EPA Emissions Inventory System that archives and processes 
emissions data submitted from the state, local and tribal agencies for 
use in the NEI. Area source emissions are listed in Appendix D of 
Tennessee's submission.

[[Page 63151]]

No nonroad and onroad sources of emissions of lead were found in the 
2008 version 2 of the NEI. A detailed discussion of the emissions 
inventory development can be found in Tennessee's submission. Table 1 
below shows the level of emissions expressed in pounds per year (lbs/
year), in the Bristol Area for the 2010 base year and the emissions 
source categories.
---------------------------------------------------------------------------

    \3\ EPA notes that area sources are only required to be 
submitted for the NEI every three years, according to the Air 
Emissions Reporting Rule. The most recent public release of the NEI 
that includes area sources is the 2008 NEI version 2. Because the 
2011 NEI is under development, that data was not available for the 
State to consider in this SIP.

                          Table 1--2010 Lead Emissions for the Bristol Area (lbs/year)
----------------------------------------------------------------------------------------------------------------
                              Year                                  Onroad      Nonroad      Area        Point
----------------------------------------------------------------------------------------------------------------
2010............................................................          0           0          66       1,280
----------------------------------------------------------------------------------------------------------------

    EPA has evaluated Tennessee's 2010 base year emissions inventory 
for the Bristol Area, and has made the preliminary determination that 
this inventory was developed consistent with EPA's guidance for 
emissions inventory. As such, pursuant to section 172(c)(3), EPA is 
proposing to approve Tennessee's 2010 base year emissions inventory for 
the Bristol Area.

IV. Conversion of Conditional Approvals for Tennessee's SIP

    As described above, on July 25, 2013, EPA took final action to 
approve Tennessee's May 10, 2013, SIP submission 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 related regulatory 
requirements for implementing the PM2.5 NAAQS, as 
promulgated in the PM2.5 PSD Increments-SILs-SMC Rule. See 
78 FR 44886. This submission was provided to satisfy the October 4, 
2012, commitment made by the State. As such, Tennessee has satisfied 
the conditions listed in EPA's previous conditional approvals for the 
infrastructure submissions (see 78 FR 44886 for additional 
information). Therefore, EPA is proposing action to convert its 
conditional approvals with respect to the PSD requirements of sections 
110(a)(2)(C), 110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 2008 8-hour 
ozone, and the PSD requirements of section 110(a)(2)(D)(i)(II) for the 
1997 annual and the 2006 24-hour PM2.5 NAAQS to full 
approvals. Since Tennessee's May 10, 2013, SIP revision, satisfies the 
conditional approval requirements for conversion to a full approval, 
the conditional approval language at 40 CFR 52.2219(c) \4\ and (e), 
included in EPA's final conditional approvals published on March 6, 
2013 and on March 26, 2013, is no longer necessary. Accordingly, EPA is 
also proposing to remove the conditional approval language relating to 
Tennessee's PSD program from the 40 CFR 52.2219 to reflect that the 
program has been fully approved.\5\
---------------------------------------------------------------------------

    \4\ The conditional approval language at 40 CFR 52.2219(c) 
incorrectly lists a conditional approval of sections 110(a)(2)(C), 
110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 2008 Lead NAAQS. This 
error stems from a typographical error included in the action 
finalizing approval of certain sections of the 2008 Lead NAAQS 
infrastructure SIP. See 78 FR 36440. EPA is publishing a correction 
notice in this Federal Register correcting this inadvertent error, 
such that the language at 40 CFR 52.2219(c) correctly describes the 
conditional approval of sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) 
and 110(a)(2)(J) for the 2008 8-hour Ozone NAAQS.
    \5\ EPA notes that through this action, the Agency is not 
proposing any revisions to the conditionally-approved provisions 
described at 40 CFR 52.2219(a), (b) or (d).
---------------------------------------------------------------------------

V. Proposed Action

    EPA is proposing to approve 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 proposing to convert 
the March 6, 2013, and March 26, 2013, conditional approvals with 
respect to the PSD requirements of sections 110(a)(2)(C), 
110(a)(2)(D)(i)(II) and 110(a)(2)(J) for the 2008 8-hour ozone, and the 
PSD requirements of section 110(a)(2)(D)(i)(II) for 1997 annual and the 
2006 24-hour PM2.5 NAAQS to full approvals. EPA is also 
proposing to remove the conditional approval language from 40 CFR 
52.2219 to reflect that the PSD program has been converted to full 
approval, and that Tennessee has met the State's obligations related to 
the previous conditional approvals. These actions are being proposed 
pursuant to section 110 of the CAA.

VI. 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 proposes to approve 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 proposal 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.
