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

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve the state implementation plan (SIP) submission, submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), to demonstrate that the State meets the requirements of sections 110(a)(1) and (2) with respect to sections 110(a)(2)(C) and (J), of the Clean Air Act (CAA or Act) for the 1997
8-hour ozone national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by the EPA, which is commonly referred to as an
‘‘infrastructure’’ SIP. TDEC certified that the Tennessee SIP contains provisions
that ensure the 1997 8-hour ozone NAAQS are implemented, enforced, and maintained in Tennessee (hereafter
referred to as ‘‘infrastructure submission’’). Tennessee’s infrastructure submission, provided to EPA on December 14, 2007, and clarified in a subsequent May 28, 2009, submission, addressed the required
infrastructure elements for the 1997 8- hour ozone NAAQS, however the subject of this notice is limited to infrastructure elements 110(a)(2)(C) and (J). All other applicable Tennessee
infrastructure elements will be addressed in a separate rulemaking.

### 3214 Federal Register / Vol. 77, No. 14 / Monday, January 23, 2012 / Proposed Rules

1 Two elements identified in section 110(a)(2) are not governed by the three year submission deadline of section 110(a)(1) because SIPs incorporating necessary local nonattainment area controls are not due within three years after promulgation of a new or revised NAAQS, but rather due at the time the nonattainment area plan requirements are due pursuant to section 172. These requirements are: (1) Submissions required by section 110(a)(2)(C) to the extent that subsection refers to a permit program as required in part D Title I of the CAA; and (2) I. Background

On July 18, 1997, EPA promulgated a new NAAQS for ozone based on 8-hour average concentrations. The 8-hour averaging period replaced the previous 1-hour averaging period, and the level of the NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm.

See 62 FR 38856. Pursuant to section 110(a)(1) of the CAA, states are required to submit SIPs meeting the requirements of section 110(a)(2) within three years after promulgation of a new or revised NAAQS. Section 110(a)(2) requires states to address basic SIP requirements, including emissions inventories, monitoring, and modeling to assure
attainment and maintenance of the NAAQS. States were required to submit
such SIPs for the 1997 8-hour ozone NAAQS to EPA no later than June 2000. However, intervening litigation over the 1997 8-hour ozone NAAQS created uncertainty about how to proceed and many states did not provide the required ‘‘infrastructure’’ SIP submission for these newly promulgated NAAQS.

On March 4, 2004, Earthjustice
submitted a notice of intent to sue related to EPA’s failure to issue findings
of failure to submit related to the ‘‘infrastructure’’ requirements for the 1997 8-hour ozone NAAQS. EPA
entered into a consent decree with Earthjustice which required EPA, among other things, to complete a Federal Register notice announcing EPA’s determinations pursuant to section 110(k)(1)(B) as to whether each state had made complete submissions to meet the requirements of section 110(a)(2) for the 1997 8-hour ozone NAAQS by December 15, 2007. Subsequently, EPA
received an extension of the date to complete this Federal Register notice until March 17, 2008, based upon agreement to make the findings with respect to submissions made by January 7, 2008. In accordance with the consent decree, EPA made completeness findings for each state based upon what the Agency received from each state as of January 7, 2008.

On March 27, 2008, EPA published a final rulemaking entitled, ‘‘Completeness Findings for Section 110(a) State Implementation Plans; 8- hour ozone NAAQS,’’ making a finding
that each state had submitted or failed to submit a complete SIP that provided the basic program elements of section 110(a)(2) necessary to implement the 1997 8-hour ozone NAAQS. See 73 FR
16205. For those states that did receive findings, such as Tennessee, the findings of failure to submit for all or a portion of a state’s implementation plan established a 24-month deadline for EPA to promulgate a Federal Implementation Plan to address the outstanding SIP elements unless, prior to that time, the affected states submitted, and EPA approved, the required SIPs. However, the findings of failure to submit did not impose sanctions or set deadlines for imposing
sanctions as described in section 179 of the CAA, because these findings do not pertain to the elements contained in the Title I part D plan for nonattainment areas as required under section 110(a)(2)(I). Additionally, the findings
of failure to submit for the infrastructure submittals are not a SIP call pursuant to section 110(k)(5).

The findings that all or portions of a state’s submission are complete
established a 12-month deadline for EPA to take action upon the complete
SIP elements in accordance with section 110(k). Tennessee’s infrastructure submission was received by EPA on December 14, 2007, and was determined to be complete on March 27, 2008, for all elements with the exception of 110(a)(2)(C) and (J). Tennessee was among other states that received a finding of failure to submit because its
infrastructure submission was not complete for elements (C) and (J) for the 1997 8-hour ozone NAAQS by March 1, 2008. Specifically, the Tennessee
infrastructure submission did not address the part C Prevention of Significant Deterioration (PSD) permit program requirements promulgated in the 1997 8-Hour Ozone NAAQS Implementation Rule New Source Review (NSR) Update—Phase 2 final rule (hereafter referred to as the Ozone Implementation NSR Update) recognizing nitrogen oxide (NOx) as an

ozone precursor. See 70 FR 71612, (November 29, 2005). On May 28, 2009,
TDEC submitted a SIP revision to EPA for federal approval which included revisions to Chapter 1200–03–09 of the Tennessee NSR program that address changes promulgated in the Ozone Implementation NSR Update. On December 5, 2011, EPA proposed to approve Tennessee’s May 28, 2009, SIP

revision. See 76 FR 75845. EPA is moving forward with final action on Tennessee’s May 28, 2009, SIP revision in an action separate from today’s action. Today’s action is proposing to approve Tennessee’s infrastructure
submission for which EPA made the findings of failure to submit on March 27, 2008. This action is not approving any specific rule, but rather proposing that Tennessee’s SIP, once two separate proposed revisions have been incorporated, meets certain CAA requirements. As discussed further below, final approval of today’s proposed rule is contingent upon the Agency first taking final action to approve Tennessee’s Ozone Implementation NSR Update (76 FR 75845) and PSD Greenhouse Gas (GHG) Tailoring Rule Revision (75 FR 68265). As such, final action approving
Tennessee’s infrastructure submission with respect to infrastructure elements 110(a)(2)(C) and (J) will not occur prior to those revisions being approved in the

SIP.

II. What elements are required under sections 110(a)(1) and (2)?

Section 110(a) of the CAA requires states to submit SIPs to provide for the implementation, maintenance, and
enforcement of a new or revised NAAQS within three years following the promulgation of such NAAQS, or within such shorter period as EPA may prescribe. Section 110(a) imposes the obligation upon states to make a SIP
submission to EPA for a new or revised NAAQS, but the contents of that submission may vary depending upon
the facts and circumstances. In particular, the data and analytical tools available at the time the state develops
and submits the SIP for a new or revised NAAQS affects the content of the
submission. The contents of such SIP submissions may also vary depending upon what provisions the state’s existing SIP already contains. In the case of the 1997 8-hour ozone NAAQS, states typically have met the basic program elements required in section 110(a)(2) through earlier SIP
submissions in connection with previous ozone NAAQS.

More specifically, section 110(a)(1) provides the procedural and timing requirements for SIPs. Section 110(a)(2) lists specific elements that states must
meet for ‘‘infrastructure’’ SIP requirements related to a newly established or revised NAAQS. As mentioned above, these requirements
include SIP infrastructure elements such as modeling, monitoring, and emissions inventories that are designed
to assure attainment and maintenance of the NAAQS. The requirements that are the subject of this proposed rulemaking
are listed below 1 and in EPA’s October


### 3215 Federal Register / Vol. 77, No. 14 / Monday, January 23, 2012 / Proposed Rules

submissions required by section 110(a)(2)(I) which pertain to the nonattainment planning requirements of part D, Title I of the CAA. Today’s proposed rulemaking does not address infrastructure elements related to section 110(a)(2)(I) or the nonattainment planning requirements of 110(a)(2)(C).

2 This rulemaking only addresses requirements for this element as they relate to attainment areas.

3 Today’s proposed rule does not address element 110(a)(2)(D)(i) (Interstate Transport) for the 1997 8- hour ozone NAAQS. Interstate transport requirements were formerly addressed by
Tennessee consistent with the Clean Air Interstate Rule (CAIR). On December 23, 2008, CAIR was remanded by the DC Circuit Court of Appeals, without vacatur, back to EPA. See North Carolina

v. EPA, 531 F.3d 896 (DC Cir. 2008). Prior to this remand, EPA took final action to approve Tennessee’s SIP revision, which was submitted to comply with CAIR. See 72 FR 46388 (August 20, 2007). In so doing, Tennessee’s CAIR SIP revision addressed the interstate transport provisions in section 110(a)(2)(D)(i) for the 1997 8-hour ozone NAAQS. In response to the remand of CAIR, EPA has promulgated a new rule to address the interstate
transport. See 76 FR 48208 (August 8, 2011) (‘‘the Transport Rule’’). That rule was recently stayed by the DC Circuit Court of Appeals. EPA’s action on element 110(a)(2)(D)(i) will be addressed in a separate action.

4 This requirement was inadvertently omitted from EPA’s October 2, 2007, memorandum entitled ‘‘Guidance on SIP Elements Required Under Section 110(a)(1) and (2) for the 1997 8-Hour Ozone
and PM2.5 National Ambient Air Quality Standards,’’ but as mentioned above is not relevant to today’s proposed rulemaking. 5 See Comments of Midwest Environmental Defense Center, dated May 31, 2011. Docket # EPA– R05–OAR–2007–1179 (adverse comments on proposals for three states in Region 5). EPA notes that these public comments on another proposal are not relevant to this rulemaking and do not have to be directly addressed in this rulemaking. EPA will respond to these comments in the appropriate rulemaking action to which they apply. 2, 2007, memorandum entitled ‘‘Guidance on SIP Elements Required Under Section 110(a)(1) and (2) for the

III. Scope of Infrastructure SIPs

EPA is currently acting upon SIPs that address the infrastructure requirements of CAA section 110(a)(1) and (2) for
ozone and PM 2.5 NAAQS for various states across the country. Commenters on EPA’s recent proposals for some states raised concerns about EPA statements that it was not addressing
certain substantive issues in the context of acting on those infrastructure SIP
submissions. 5 Those Commenters specifically raised concerns involving provisions in existing SIPs and with EPA’s statements in other proposals that it would address two issues separately and not as part of actions on the infrastructure SIP submissions: (i) Existing provisions related to excess emissions during periods of start-up, shutdown, or malfunction at sources, that may be contrary to the CAA and EPA’s policies addressing such excess emissions (SSM); and (ii) existing provisions related to ‘‘director’s
variance’’ or ‘‘director’s discretion’’ that purport to permit revisions to SIP approved emissions limits with limited public process or without requiring further approval by EPA, that may be contrary to the CAA (director’s discretion). EPA notes that there are two
other substantive issues for which EPA likewise stated in other proposals that it would address the issues separately: (i) Existing provisions for minor source new source review programs that may be inconsistent with the requirements of the CAA and EPA’s regulations that pertain to such programs (minor source NSR); and (ii) existing provisions for PSD programs that may be inconsistent with current requirements of EPA’s ‘‘Final NSR Improvement Rule,’’ 67 FR 80186 (December 31, 2002), as amended by 72 FR 32526 (June 13, 2007) (NSR Reform). In light of the comments, EPA
believes that its statements in various proposed actions on infrastructure SIPs with respect to these four individual issues should be explained in greater depth. It is important to emphasize that EPA is taking the same position with respect to these four substantive issues
in this action on the infrastructure SIPs for the 1997 8-hour ozone NAAQS from

Tennessee.

EPA intended the statements in the other proposals concerning these four issues merely to be informational, and to provide general notice of the potential existence of provisions within the existing SIPs of some states that might require future corrective action. EPA did not want states, regulated entities, or members of the public to be under the misconception that the Agency’s approval of the infrastructure SIP submission of a given state should be interpreted as a re-approval of certain types of provisions that might exist buried in the larger existing SIP for such state. Thus, for example, EPA explicitly noted that the Agency believes that some states may have existing SIP approved SSM provisions that are contrary to the CAA and EPA policy, but that ‘‘in this rulemaking, EPA is not proposing to approve or disapprove any existing state provisions with regard to excess emissions during SSM of operations at facilities.’’ EPA further explained, for informational purposes, that ‘‘EPA plans to address such State regulations in the future.’’ EPA made similar statements, for similar reasons, with respect to the director’s discretion, minor source NSR, and NSR Reform issues. EPA’s objective was to make clear that approval of an infrastructure
SIP for these ozone and PM2.5 NAAQS should not be construed as explicit or implicit re-approval of any existing provisions that relate to these four substantive issues. EPA is reiterating that position in this action on the
infrastructure SIP for Tennessee.

Unfortunately, the Commenters and others evidently interpreted these
statements to mean that EPA considered action upon the SSM provisions and the
other three substantive issues to be integral parts of acting on an infrastructure SIP submission, and therefore that EPA was merely postponing taking final action on the
issues in the context of the
infrastructure SIPs. This was not EPA’s intention. To the contrary, EPA only meant to convey its awareness of the potential for certain types of deficiencies in existing SIPs, and to prevent any misunderstanding that it was reapproving any such existing provisions. EPA’s intention was to convey its position that the statute does not require that infrastructure SIPs address these specific substantive issues in existing SIPs and that these issues may be dealt with separately, outside the context of acting on the
infrastructure SIP submission of a state. To be clear, EPA did not mean to imply that it was not taking a full final agency
action on the infrastructure SIP submission with respect to any
substantive issue that EPA considers to be a required part of acting on such submissions under section 110(k) or under section 110(c). Given the confusion evidently resulting from
EPA’s statements in those other proposals, however, we want to explain more fully the Agency’s reasons for concluding that these four potential


### 3216 Federal Register / Vol. 77, No. 14 / Monday, January 23, 2012 / Proposed Rules

6 For example, section 110(a)(2)(E) provides that states must provide assurances that they have adequate legal authority under state and local law to carry out the SIP; section 110(a)(2)(C) provides that states must have a substantive program to address certain sources as required by part C of the CAA; section 110(a)(2)(G) provides that states must have both legal authority to address emergencies and substantive contingency plans in the event of such an emergency. 7 For example, section 110(a)(2)(D)(i) requires
EPA to be sure that each state’s SIP contains adequate provisions to prevent significant contribution to nonattainment of the NAAQS in other states. This provision contains numerous terms that require substantial rulemaking by EPA in order to determine such basic points as what constitutes significant contribution. See ‘‘Rule To Reduce Interstate Transport of Fine Particulate Matter and Ozone (Clean Air Interstate Rule); Revisions to Acid Rain Program; Revisions to the

NO X SIP Call; Final Rule,’’ 70 FR 25162 (May 12, 2005) (defining, among other things, the phrase ‘‘contribute significantly to nonattainment’’).

8 See id., 70 FR 25162, at 63–65 (May 12, 2005) (explaining relationship between timing requirement of section 110(a)(2)(D) versus section 110(a)(2)(I)).

9 EPA issued separate guidance to states with respect to SIP submissions to meet section 110(a)(2)(D)(i) for the 1997 ozone and 1997 PM2.5 NAAQS. See ‘‘Guidance for State Implementation Plan (SIP) Submissions to Meet Current Outstanding Obligations Under Section 110(a)(2)(D)(i) for the 8–Hour Ozone and PM 2.5 National Ambient Air Quality Standards,’’ from William T. Harnett, Director Air Quality Policy Division OAQPS, to Regional Air Division Director, Regions I–X, dated August 15, 2006. 10 For example, implementation of the 1997 PM 2.5 NAAQS required the deployment of a system of
new monitors to measure ambient levels of that new indicator species for the new NAAQS. substantive issues in existing SIPs may be addressed separately from actions on
infrastructure SIP submissions.

The requirement for the SIP
submissions at issue arises out of CAA section 110(a)(1). That provision requires that states must make a SIP submission ‘‘within 3 years (or such shorter period as the Administrator may prescribe) after the promulgation of a national primary ambient air quality standard (or any revision thereof)’’ and that these SIPs are to provide for the ‘‘implementation, maintenance, and enforcement’’ of such NAAQS. Section 110(a)(2) includes a list of specific elements that ‘‘[e]ach such plan’’
submission must meet. EPA has historically referred to these particular
submissions that states must make after the promulgation of a new or revised NAAQS as ‘‘infrastructure SIPs.’’ This specific term does not appear in the statute, but EPA uses the term to distinguish this particular type of SIP submission designed to address basic structural requirements of a SIP from other types of SIP submissions designed to address other different requirements,
such as ‘‘nonattainment SIP’’ submissions required to address the nonattainment planning requirements of part D, ‘‘regional haze SIP’’ submissions required to address the visibility protection requirements of CAA section 169A, NSR permitting program submissions required to address the requirements of part D, and a host of other specific types of SIP submissions that address other specific matters.

Although section 110(a)(1) addresses the timing and general requirements for these infrastructure SIPs, and section 110(a)(2) provides more details concerning the required contents of these infrastructure SIPs, EPA believes that many of the specific statutory provisions are facially ambiguous. In particular, the list of required elements provided in section 110(a)(2) contains a wide variety of disparate provisions, some of which pertain to required legal authority, some of which pertain to required substantive provisions, and some of which pertain to requirements for both authority and substantive provisions. 6 Some of the elements of section 110(a)(2) are relatively straightforward, but others clearly require interpretation by EPA through rulemaking, or recommendations through guidance, in order to give specific meaning for a particular NAAQS. 7

Notwithstanding that section 110(a)(2) provides that ‘‘each’’ SIP submission must meet the list of requirements therein, EPA has long noted that this literal reading of the statute is internally inconsistent, insofar as section 110(a)(2)(I) pertains to nonattainment SIP requirements that could not be met on the schedule provided for these SIP submissions in section 110(a)(1). 8 This
illustrates that EPA must determine which provisions of section 110(a)(2) may be applicable for a given
infrastructure SIP submission. Similarly, EPA has previously decided
that it could take action on different parts of the larger, general ‘‘infrastructure SIP’’ for a given NAAQS
without concurrent action on all subsections, such as section 110(a)(2)(D)(i), because the Agency
bifurcated the action on these latter ‘‘interstate transport’’ provisions within section 110(a)(2) and worked with states to address each of the four prongs of section 110(a)(2)(D)(i) with substantive administrative actions proceeding on
different tracks with different
schedules. 9 This illustrates that EPA may conclude that subdividing the applicable requirements of section 110(a)(2) into separate SIP actions may sometimes be appropriate for a given NAAQS where a specific substantive action is necessitated, beyond a mere submission addressing basic structural aspects of the state’s implementation plans. Finally, EPA notes that not every element of section 110(a)(2) would be relevant, or as relevant, or relevant in the same way, for each new or revised NAAQS and the attendant infrastructure SIP submission for that NAAQS. For example, the monitoring requirements that might be necessary for purposes of section 110(a)(2)(B) for one NAAQS could be very different than what might be necessary for a different pollutant. Thus, the content of an infrastructure
SIP submission to meet this element from a state might be very different for an entirely new NAAQS, versus a minor revision to an existing NAAQS. 10

Similarly, EPA notes that other types of SIP submissions required under the statute also must meet the requirements of section 110(a)(2), and this also demonstrates the need to identify the applicable elements for other SIP submissions. For example, nonattainment SIPs required by part D
likewise have to meet the relevant subsections of section 110(a)(2) such as section 110(a)(2)(A) or (E). By contrast,
it is clear that nonattainment SIPs would not need to meet the portion of section 110(a)(2)(C) that pertains to part C, i.e., the PSD requirements applicable

in attainment areas. Nonattainment SIPs required by part D also would not need to address the requirements of section 110(a)(2)(G) with respect to emergency episodes, as such requirements would
not be limited to nonattainment areas. As this example illustrates, each type of SIP submission may implicate some subsections of section 110(a)(2) and not
others.

Given the potential for ambiguity of the statutory language of section 110(a)(1) and (2), EPA believes that it is appropriate for EPA to interpret that language in the context of acting on the infrastructure SIPs for a given NAAQS. Because of the inherent ambiguity of the list of requirements in section 110(a)(2), EPA has adopted an approach in which it reviews infrastructure SIPs against this list of elements ‘‘as applicable.’’ In other words, EPA assumes that Congress
could not have intended that each and every SIP submission, regardless of the purpose of the submission or the NAAQS in question, would meet each of the requirements, or meet each of them in the same way. EPA elected to use guidance to make recommendations
for infrastructure SIPs for these ozone
and PM 2.5 NAAQS.

On October 2, 2007, EPA issued guidance making recommendations for
the infrastructure SIP submissions for both the 1997 8-hour ozone NAAQS and

13 Id., at attachment A, page 1.

14 Id., at page 4. In retrospect, the concerns raised by commenters with respect to EPA’s approach to
some substantive issues indicates that the statute is not so ‘‘self explanatory,’’ and indeed is sufficiently ambiguous that EPA needs to interpret it in order to explain why these substantive issues do not need
to be addressed in the context of infrastructure SIPs and may be addressed at other times and by other

means. 15 See ‘‘Guidance on SIP Elements Required Under Sections 110(a)(1) and (2) for the 2006 24- Hour Fine Particle (PM 2.5 ) National Ambient Air Quality Standards (NAAQS),’’ from William T, Harnett, Director Air Quality Policy Division, to Regional Air Division Directors, Regions I–X, dated September 25, 2009 (the ‘‘2009 Guidance’’). 16 EPA has recently issued a SIP call to rectify a specific SIP deficiency related to the SSM issue. See, ‘‘Finding of Substantial Inadequacy of Implementation Plan; Call for Utah State Implementation Plan Revision,’’ 76 FR 21639 (April 18, 2011).

17 EPA has recently utilized this authority to correct errors in past actions on SIP submissions related to PSD programs. See ‘‘Limitation of Approval of Prevention of Significant DeteriorationProvisions Concerning Greenhouse Gas EmittingSources in State Implementation Plans; Final Rule,’’ 75 FR 82536 (December 30, 2010). EPA has previously used its authority under CAA 110(k)(6) to remove numerous other SIP provisions that the Agency determined it had approved in error. See 61 FR 38664 (July 25, 1996) and 62 FR 34641 (June 27, 1997) (corrections to American Samoa, Arizona, California, Hawaii, and Nevada SIPs); 69 FR 67062

Continued the 1997 PM 2.5 NAAQS. 11 Within this guidance document, EPA described the duty of states to make these submissions to meet what the Agency characterized
as the ‘‘infrastructure’’ elements for SIPs, which it further described as the ‘‘basic SIP requirements, including emissions inventories, monitoring, and modeling to assure attainment and
maintenance of the standards.’’ 12 As
further identification of these basic structural SIP requirements, ‘‘attachment A’’ to the guidance document included a short description
of the various elements of section 110(a)(2) and additional information about the types of issues that EPA considered germane in the context of
such infrastructure SIPs. EPA emphasized that the description of the basic requirements listed on attachment
A was not intended ‘‘to constitute an interpretation of’’ the requirements, and was merely a ‘‘brief description of the required elements.’’ 13 EPA also stated its belief that with one exception, these requirements were ‘‘relatively self explanatory, and past experience with SIPs for other NAAQS should enable States to meet these requirements with assistance from EPA Regions.’’ 14 However, for the one exception to that general assumption (i.e., how states should proceed with respect to the requirements of section 110(a)(2)(G) for
the 1997 PM 2.5 NAAQS), EPA gave much more specific recommendations.
But for other infrastructure SIP submittals, and for certain elements of
the submittals for the 1997 PM 2.5 NAAQS, EPA assumed that each State would work with its corresponding EPA regional office to refine the scope of a
State’s submittal based on an assessment of how the requirements of section 110(a)(2) should reasonably apply to the basic structure of the State’s implementation plans for the NAAQS in question.

On September 25, 2009, EPA issued guidance to make recommendations to states with respect to the infrastructure SIPs for the 2006 PM2.5 NAAQS. 15 In the 2009 Guidance, EPA addressed a
number of additional issues that were not germane to the infrastructure SIPs
for the 1997 8-hour ozone and 1997

PM 2.5 NAAQS, but were germane to
these SIP submissions for the 2006

PM 2.5 NAAQS ( e.g., the requirements of section 110(a)(2)(D)(i) that EPA had
bifurcated from the other infrastructure elements for those specific 1997 ozone
and PM 2.5 NAAQS). Significantly,
neither the 2007 Guidance nor the 2009 Guidance explicitly referred to the SSM, director’s discretion, minor source NSR, or NSR Reform issues as among specific substantive issues EPA expected states
to address in the context of the infrastructure SIPs, nor did EPA give any more specific recommendations with respect to how states might address such issues even if they elected to do so.
The SSM and director’s discretion issues implicate section 110(a)(2)(A),
and the minor source NSR and NSR Reform issues implicate section 110(a)(2)(C). In the 2007 Guidance and the 2009 Guidance, however, EPA did
not indicate to states that it intended to interpret these provisions as requiring a
substantive submission to address these specific issues in existing SIP provisions
in the context of the infrastructure SIPs for these NAAQS. Instead, EPA’s 2007 Guidance merely indicated its belief
that the states should make submissions in which they established that they have the basic SIP structure necessary to implement, maintain, and enforce the NAAQS. EPA believes that states can establish that they have the basic SIP structure, notwithstanding that there may be potential deficiencies within the existing SIP. Thus, EPA’s proposals for
other states mentioned these issues not because the Agency considers them
issues that must be addressed in the
context of an infrastructure SIP as required by section 110(a)(1) and (2),
but rather because EPA wanted to be clear that it considers these potential existing SIP problems as separate from the pending infrastructure SIP actions.
The same holds true for this action on
the infrastructure SIPs for Tennessee.

EPA believes that this approach to the infrastructure SIP requirement is
reasonable because it would not be feasible to read section 110(a)(1) and (2) to require a top to bottom, stem to stern, review of each and every provision of an existing SIP merely for purposes of assuring that the state in question has
the basic structural elements for a functioning SIP for a new or revised NAAQS. Because SIPs have grown by accretion over the decades as statutory and regulatory requirements under the CAA have evolved, they may include some outmoded provisions and historical artifacts that, while not fully up to date, nevertheless may not pose a significant problem for the purposes of ‘‘implementation, maintenance, and
enforcement’’ of a new or revised NAAQS when EPA considers the overall effectiveness of the SIP. To the contrary, EPA believes that a better approach is for EPA to determine which specific SIP elements from section 110(a)(2) are applicable to an infrastructure SIP for a given NAAQS, and to focus attention on those elements that are most likely to need a specific SIP revision in light of the new or revised NAAQS. Thus, for example, EPA’s 2007 Guidance specifically directed states to focus on the requirements of section 110(a)(2)(G) for the 1997 p.m. 2.5 NAAQS because of the absence of underlying EPA regulations for emergency episodes for this NAAQS and an anticipated absence of relevant provisions in existing SIPs.

Finally, EPA believes that its approach is a reasonable reading of section 110(a)(1) and (2) because the statute provides other avenues and mechanisms to address specific substantive deficiencies in existing SIPs. These other statutory tools allow the Agency to take appropriate tailored action, depending upon the nature and severity of the alleged SIP deficiency. Section 110(k)(5) authorizes EPA to issue a ‘‘SIP call’’ whenever the Agency
determines that a state’s SIP is substantially inadequate to attain or maintain the NAAQS, to mitigate interstate transport, or otherwise to comply with the CAA. 16 Section 110(k)(6) authorizes EPA to correct errors in past actions, such as past approvals of SIP submissions. 17


### 3218 Federal Register / Vol. 77, No. 14 / Monday, January 23, 2012 / Proposed Rules

(November 16, 2004) (corrections to California SIP); and 74 FR 57051 (November 3, 2009) (corrections to Arizona and Nevada SIPs).

18 EPA has recently disapproved a SIP submission from Colorado on the grounds that it would have included a director’s discretion provision inconsistent with CAA requirements, including section 110(a)(2)(A). See 75 FR 42342, 42344 (July 21, 2010) (proposed disapproval of director’s discretion provisions); 76 FR 4540 (January 26, 2011) (final disapproval of such provisions). 19 On December 30, 2010, EPA published a final rulemaking, ‘‘Limitation of Approval of Prevention of Significant Deterioration Concerning Greenhouse Gas Emitting-Sources in State Implementation Plans: Final Rule’’ (75 FR 82536), which narrowed its previous approval of PSD programs as applicable to GHG-emitting sources in SIPs for 24 states, including Tennessee. Specifically, in the PSD Narrowing Rule, EPA withdrew its previous approval of Tennessee’s SIP to the extent it applied PSD requirements to GHG-emitting sources below the thresholds described in the final Tailoring Rule. The provisions of SIPs from which EPA withdrew its approval are treated as submitted by the state but not yet acted upon by EPA. Once a state submits a SIP revision for EPA’s approval to incorporate the Tailoring Rule thresholds, EPA will treat the approval as removing the no-longer-approved provisions. See 75 FR at 82540.

20 Tennessee requested parallel processing of this SIP revision because on the date of its submittal, the revision was not yet state-effective. Under parallel processing an EPA Regional Office works closely with the state while developing new or revised regulations. Generally the state submits a copy of the proposed regulation or other revisions to EPA before conducting its public hearing. EPA then proceeds with a federal rulemaking to add to or revise the SIP during approximately the same time during which the state is holding its public hearing. The state and EPA thus provide for public comment periods on both the state and federal action in parallel.

21 EPA’s proposed approval of: (1) Tennessee’s PSD/NSR regulations which address the Ozone Implementation NSR Update requirements and (2) Tennessee’s PSD GHG Tailoring Rule revisions which addresses the thresholds for GHG permitting applicability in Tennessee ( See 76 FR 75845 and 75 FR 68265). Significantly, EPA’s determination that
an action on the infrastructure SIP is not the appropriate time and place to address all potential existing SIP problems does not preclude the Agency’s subsequent reliance on provisions in section 110(a)(2) as part of
the basis for action at a later time. For example, although it may not be appropriate to require a state to eliminate all existing inappropriate director’s discretion provisions in the course of acting on the infrastructure SIP, EPA believes that section 110(a)(2)(A) may be among the statutory bases that the Agency cites in the course of addressing the issue in a subsequent

action. 18

IV. What is EPA’s analysis of how Tennessee addressed the elements (C) and (J) of sections 110(a)(1) and (2) ‘‘infrastructure’’ provisions?

The Tennessee infrastructure submission addresses the provisions of sections 110(a)(1) and (2) with respect to elements (C) and (J), as described below.

1. 110(a)(2)(C) Program for enforcement of control measures including review of proposed new

sources. In this action, EPA is proposing to approve Tennessee’s infrastructure SIP for the 8-hour ozone NAAQS with respect to the general requirement in section 110(a)(2)(C) to include a program in the SIP that regulates the modification and construction of any stationary source as necessary to assure that the NAAQS are achieved. Chapter

1200–3–9, Construction and Operating Permits, of Tennessee’s SIP pertains to the construction of any new major stationary source or any project at an existing major stationary source in an area designated as nonattainment,
attainment or unclassifiable. This regulation addresses many of the infrastructure element 110(a)(2)(C) requirements, however, as discussed below, there are two pending revisions to the Tennessee SIP (including revisions to Chapter 1200–3–9) that are necessary to meet the requirements of infrastructure element 110(a)(2)(C).
These two revisions are related to the Ozone Implementation NSR Update and the ‘‘Prevention of Significant
Deterioration and Title V Greenhouse Gas Tailoring Rule’’ (75 FR 31514). The first pending revision to the Tennessee SIP (Ozone Implementation NSR Update revisions) was submitted by TDEC on May 28, 2009. That revision modifies provisions of the state’s SIP at Chapter 1200–3–9, Construction and Operating Permits. In addition to meeting the requirements of the Ozone Implementation NSR Update, these revisions are also necessary to address portions of the infrastructure SIP requirements described at element 110(a)(2)(C). Specifically, the May 28, 2009, SIP revisions address the Ozone Implementation NSR Update requirements to include NOx as an ozone precursor for permitting purposes. These revisions involve changes to major source thresholds for
sources in certain classes of nonattainment areas, changes to offset ratios for marginal, moderate, serious, severe, and extreme ozone nonattainment areas, provisions addressing offset requirements for
facilities that shut down or curtail operation, and a requirement stating
that NOx emissions are ozone precursors. On December 5, 2011, EPA proposed approval of Tennessee’s May 28, 2009, submission. See 76 FR 75845.
EPA will take final action on these regulations in a separate action from
this notice.

The second pending rulemaking pertains to revisions to the PSD program promulgated in the GHG Tailoring Rule. On November 5, 2010, EPA published a rulemaking proposing to approve Tennessee’s PSD GHG Tailoring Rule revision, 19 which was submitted to EPA on August 30, 2010, for parallel processing. 20 See 75 FR 68265. This proposed revision establishes appropriate emission thresholds for determining which new stationary sources and modification projects become subject to Tennessee’s PSD permitting requirements for their GHG emissions, and thereby addresses the thresholds for GHG permitting applicability in Tennessee. On January 11, 2012, EPA received Tennessee’s PSD GHG Tailoring Rule revision final
submittal. EPA will take final action on these regulations in a separate action
from this notice.

Both of these proposed SIP

revisions 21 address requisite requirements of infrastructure element 110(a)(2)(C), therefore, today’s action to propose approval of infrastructure SIP element 110(a)(2)(C) is contingent upon EPA taking final action to approve each of these pending revisions into the Tennessee SIP. Final action regarding today’s proposed approval of infrastructure SIP element 110(a)(2)(C) will not occur prior to final approval of
these related SIP revisions.

EPA also notes that today’s action is not proposing to approve or disapprove the State’s existing minor NSR program
itself to the extent that it is inconsistent with EPA’s regulations governing this program. EPA believes that a number of states may have minor NSR provisions that are contrary to the existing EPA regulations for this program. EPA
intends to work with states to reconcile state minor NSR programs with EPA’s regulatory provisions for the program. The statutory requirements of section 110(a)(2)(C) provide for considerable flexibility in designing minor NSR programs, and EPA believes it may be time to revisit the regulatory requirements for this program to give the states an appropriate level of flexibility to design a program that meets their particular air quality concerns, while assuring reasonable consistency across the country in protecting the NAAQS with respect to
new and modified minor sources.

EPA has made the preliminary
determination that Tennessee’s SIP and practices are adequate for program
enforcement of control measures including review of proposed new
sources related to the 1997 8-hour ozone NAAQS.


### 3219 Federal Register / Vol. 77, No. 14 / Monday, January 23, 2012 / Proposed Rules

22 EPA’s proposed approval of: (1) Tennessee’s PSD/NSR regulations which addresses the Ozone Implementation NSR Update requirements and (2) Tennessee’s PSD GHG Tailoring Rule revisions which addresses the thresholds for GHG permitting applicability in Tennessee ( See 76 FR 75845 and 75 FR 68265). 2. 110(a)(2)(J). In this action, EPA is also proposing to approve Tennessee’s
infrastructure SIP for the 8-hour ozone NAAQS with respect to the general requirement in section 110(a)(2)(J) to include a program in the SIP that provides for meeting the applicable consultation requirements of section 121, the public notification requirements of section 127; and the PSD and visibility protection requirements of part C of the Act.

110(a)(2)(J) (121 consultation) Consultation with government officials: Chapter 1200–3–9 Construction and Operating Permits, as well as the Regional Haze Implementation Plan (which allows for consultation between appropriate state, local, and tribal air pollution control agencies as well as the corresponding Federal Land Managers), provide for consultation with government officials whose jurisdictions might be affected by SIP development activities. Tennessee adopted state-wide consultation procedures for the implementation of transportation conformity. These consultation procedures include considerations associated with the development of
mobile inventories for SIPs. Implementation of transportation conformity as outlined in the consultation procedures requires TDEC to consult with federal, state and local transportation and air quality agency officials on the development of motor vehicle emissions budgets. EPA approved Tennessee’s consultation procedures on May 16, 2003 (68 FR 26492). EPA has made the preliminary
determination that Tennessee’s SIP and practices adequately demonstrate consultation with government officials
related to the 1997 8-hour ozone NAAQS when necessary.

110(a)(2)(J) (127 public notification) Public notification: TDEC has public notice mechanisms in place to notify the public of ozone and other pollutant forecasting, including an air quality monitoring Web site with ground level ozone alerts, http://tn.gov/environment/ apc/ozone/. Chapter 1200–3–15, Emergency Episode Requirements, requires that TDEC notify the public of any air pollution episode or NAAQS
violation. EPA has made the preliminary determination that Tennessee’s SIP and practices adequately demonstrate the State’s ability to provide public notification
related to the 1997 8-hour ozone NAAQS when necessary.

110(a)(2)(J) (Part C) PSD and visibility protection: Tennessee demonstrates its authority to regulate new and modified sources of ozone precursors, volatile organic compounds, and NOx to assist in the protection of air quality in Chapter 1200–3–9, Construction and Operating Permits. As with infrastructure element 110(a)(2)(C), infrastructure element 110(a)(2)(J) also requires compliance with applicable provisions of the PSD program described in part C of the Act. Accordingly, the pending EPA actions on the Ozone Implementation NSR Update and GHG Tailoring Rule

revisions to Tennessee’s SIP are likewise prerequisites to today’s proposed action to approve the State’s infrastructure element 110(a)(2)(J). See the discussion for element 110(a)(2)(C) above for a description of these two pending revisions to the Tennessee SIP.

Both of these proposed SIP

revisions 22 address requisite requirements of infrastructure element 110(a)(2)(J) (PSD and visibility protection), therefore, today’s action to propose approval of infrastructure SIP element 110(a)(2)(J) (PSD and visibility protection) is contingent upon EPA taking final action to approve each of these pending revisions into the Tennessee SIP. Final action regarding today’s proposed approval of infrastructure SIP element 110(a)(2)(J) (PSD and visibility protection) will not occur prior to final approval of these
related SIP revisions.

With regard to the applicable requirements for visibility protection, EPA recognizes that states are subject to visibility and regional haze program requirements under part C of the Act (which includes sections 169A and 169B). In the event of the establishment of a new NAAQS, however, the visibility and regional haze program requirements under part C do not change. Thus, EPA finds that there is no new visibility obligation ‘‘triggered’’ under section 110(a)(2)(J) when a new NAAQS becomes effective. This would
be the case even in the event a secondary PM 2.5 NAAQS for visibility is established, because this NAAQS would not affect visibility requirements under part C. Tennessee has submitted SIP revisions for approval to satisfy the requirements of the CAA Section 169A and 169B, and the regional haze and best available retrofit technology rules
contained in 40 CFR 51.308. These revisions are currently under review and will be acted on in a separate action. EPA has made the preliminary
determination that Tennessee’s SIP and practices adequately demonstrate the State’s ability to implement PSD programs and to provide for visibility protection related to the 1997 8-hour ozone NAAQS when necessary.

V. Proposed Action

As described above, following final approval of the proposed revisions to the Tennessee SIP regarding the Ozone Implementation NSR Update and the PSD GHG Tailoring Rule Revision,
TDEC will have addressed elements 110(a)(2)(C) and (J) of the CAA 110(a)(1) and (2) SIP requirements pursuant to EPA’s October 2, 2007, guidance to
ensure that the 1997 8-hour ozone NAAQS are implemented, enforced, and
maintained in Tennessee. EPA is proposing to approve Tennessee’s
infrastructure submission for the 1997 8-hour ozone NAAQS for these elements, contingent upon the final approval of those revisions, because its December 12, 2007, and May 28, 2009,
submissions will then be consistent
with 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.

See 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 proposed 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 proposed 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


### 3220 Federal Register / Vol. 77, No. 14 / Monday, January 23, 2012 / Proposed Rules

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 proposed rule 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.

**ACTION :**  Proposed rule.

**SUMMARY :**  The EPA is proposing two separate and independent determinations regarding the Springfield (Western Massachusetts)
moderate 1997 8-hour ozone nonattainment area. First, EPA is proposing to determine that the Western
Massachusetts nonattainment area has attained the 1997 8-hour National Ambient Air Quality Standard (NAAQS) for ozone, based upon complete, quality-assured, certified ambient air monitoring data that show the area has
monitored attainment of the 1997 8- hour ozone NAAQS for the 2007–2009 and 2008–2010 monitoring periods. Preliminary data for 2011 indicate the
area continues to attain the standard. If this proposed determination is made final, under the provisions of EPA’s ozone implementation rule, the requirements for this area to submit an attainment demonstration, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans related to
attainment of the 1997 8-hour ozone NAAQS shall be suspended for so long
as the area continues to attain the 1997 ozone NAAQS. Second, based on complete, quality-assured and certified air monitoring data for 2007–2009, EPA is proposing to determine that the
Western Massachusetts nonattainment
area also attained the 1997 ozone NAAQS as of June 15, 2010, its applicable attainment date.
