Approval and Promulgation of State Implementation Plan Revisions; 
Infrastructure Requirements for the 1997 8-Hour Ozone National Ambient 
Air Quality Standard; Utah

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is approving and conditionally approving the State 
Implementation Plan (SIP) submission from the State of Utah to 
demonstrate that the SIP meets the requirements of sections 110(a)(1) 
and (2) of the Clean Air Act (CAA) for the National Ambient Air Quality 
Standard (NAAQS) promulgated for ozone on July 18, 1997. Section 
110(a)(1) of the CAA requires that each state, after a new or revised 
NAAQS is promulgated, review their SIPs to ensure that they meet the 
requirements of the ``infrastructure elements'' of section 110(a)(2). 
The State of Utah submitted two certifications, dated December 3, 2007, 
and December 21, 2009, that its SIP met these requirements for the 1997 
ozone NAAQS. The December 3, 2007 certification was determined to be 
complete on March 27, 2008 (73 FR 16205).

DATES: Effective Date: This final rule is effective August 22, 2011.

I. Background

    On July 18, 1997, EPA promulgated 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 (62 FR 38856). By 
statute, SIPs meeting the requirements of sections 110(a)(1) and (2) 
are to be submitted by states within three years after promulgation of 
a new or revised standard. Section 110(a)(2) provides basic 
requirements for SIPs, including emissions inventories, monitoring, and 
modeling, to assure attainment and maintenance of the standards. These 
requirements are set out in several ``infrastructure elements,'' listed 
in section 110(a)(2).
    Section 110(a) imposes the obligation upon states to make a SIP 
submission to EPA for a new or revised NAAQS, and the contents of that 
submission may vary depending upon the facts and circumstances. In 
particular, the data and analytical tools available at the time a state 
develops and submits its 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 a state's existing SIP already 
contains. In the case of the 1997 ozone NAAQS, states typically have 
met the basic program elements required in section 110(a)(2) through 
earlier SIP submissions in connection with previous NAAQS. In a 
guidance issued on October 2, 2007, EPA noted that, to the extent an 
existing SIP already meets the section 110(a)(2) requirements, states 
need only to certify that fact via a letter to EPA.\1\
---------------------------------------------------------------------------

    \1\ Memorandum from William T. Harnett, Director, Air Quality 
Policy Division, ``Guidance on SIP Elements Required Under Sections 
110(a)(1) and (2) for the 1997 8-Hour Ozone and PM2.5 
National Ambient Air Quality Standards'' (Oct. 2, 2007).
---------------------------------------------------------------------------

    On March 27, 2008, EPA published a final rule entitled, 
``Completeness Findings for Section 110(a) State Implementation Plans 
for the 8-hour Ozone NAAQS'' (73 FR 16205). In the rule, EPA made a 
finding for each state that it had submitted or had 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. In 
particular, EPA found that Utah had submitted a complete SIP 
(``Infrastructure SIP'') to meet these requirements.
    On May 23, 2011, EPA published a notice of proposed rulemaking 
(NPR) for the State of Utah (76 FR 29688) to act on the State's 
Infrastructure SIP for the 1997 ozone NAAQS. Specifically, in the NPR 
EPA proposed approval of Utah's SIP as meeting the requirements of all 
section 110(a)(2) elements with respect to the 1997 ozone NAAQS, aside 
from elements 110(a)(2)(D)(i), 110(a)(2)(I), and the visibility 
protection requirement of element 110(a)(2)(J), on which EPA did not 
propose action.\2\
---------------------------------------------------------------------------

    \2\ See the NPR (76 FR 29688) for further explanation regarding 
the omission of elements 110(a)(2)(D)(i) and 110(a)(2)(I) from the 
proposal.
---------------------------------------------------------------------------

    In the May 23, 2011 NPR, EPA proposed to conditionally approve 
element 110(a)(2)(B) for the 1997 ozone NAAQS. EPA had discovered 
certain deficiencies in Utah's monitoring network plan and Utah 
formally committed to submitting an adequate annual monitoring plan not 
later than one year after the date of this final action to correct 
those deficiencies.\3\ In the NPR, EPA also stated that if Utah does 
not implement the measures specified in its commitment within one year 
after the date of this final action, EPA's conditional approval will 
automatically revert to disapproval of the infrastructure SIP for 
section 110(a)(2)(B) for the 1997 ozone NAAQS.
---------------------------------------------------------------------------

    \3\ The specific measures Utah will take are detailed in the 
commitment letter, which may be found in the docket for this action.
---------------------------------------------------------------------------

    EPA proposed to approve element 110(a)(2)(C) for the 1997 ozone 
NAAQS in the event that the State clarified (or modified) its December 
3, 2007 and December 21, 2009 certifications to ensure consistency with 
two rules related to regulation of greenhouse gas (GHG) emissions: 
``Prevention of Significant Deterioration and Title V Greenhouse Gas 
Tailoring Rule'' (``Tailoring Rule''), 75 FR 31514 (June 3, 2010), and 
``Limitation of Approval of Prevention of Significant Deterioration 
Provisions Concerning Greenhouse Gas Emitting-Sources in State 
Implementation Plans'' (``PSD SIP Narrowing Rule''), 75 FR 82536 (Dec. 
30, 2010). In the PSD SIP Narrowing Rule, EPA withdrew its previous 
approval of Utah's prevention of significant deterioration (PSD) 
program to the extent that it applied PSD permitting to GHG emissions 
increases from GHG-emitting sources below thresholds set in the 
Tailoring Rule. EPA withdrew its approval on the basis that the State 
lacked sufficient resources to issue PSD permits to such sources at the 
statutory thresholds in effect in the previously-approved PSD program. 
After the PSD SIP Narrowing Rule, the portion of Utah's PSD SIP from 
which EPA withdrew its approval had the status of having been submitted 
to EPA but not yet acted upon. In its December 3, 2007 and December 21, 
2009 certifications, Utah relied on its PSD program as approved at that 
date--which was before December 30, 2010, the effective date of the PSD 
SIP Narrowing Rule--to satisfy the requirements of infrastructure 
element 110(a)(2)(C). Given EPA's basis for the PSD SIP Narrowing Rule, 
EPA proposed approval of the Utah Infrastructure SIP for infrastructure 
element (C) if either the State clarified (or modified) its 
certification to make clear that the State relies only on the portion 
of the PSD program that remains approved after the PSD SIP Narrowing 
Rule issued on December 30, 2010, and for which the State has 
sufficient resources to implement, or the State acted to withdraw from 
EPA consideration the remaining portion of its PSD program submission 
that would have applied PSD permitting to GHG sources below the 
Tailoring Rule thresholds. On June 22, 2011, EPA received a letter from 
Utah clarifying that the State relies only on the portion of the PSD 
program that remains approved after the PSD SIP

Narrowing Rule issued on December 30, 2010.\4\
---------------------------------------------------------------------------

    \4\ Utah's June 22, 2011 clarification letter is available in 
the docket for this action.
---------------------------------------------------------------------------

    EPA's proposed approval of elements 110(a)(2)(C) and (J) for the 
1997 ozone NAAQS was also contingent on the final approval of the 
State's August 7, 2008 submittal. The State's PSD program, as 
submitted, for the most part incorporates by reference the Federal 
program at 40 CFR 52.21. The August 7, 2008 submittal updates the date 
of incorporation by reference of the State's PSD program to July 7, 
2007, therefore incorporating EPA's phase 2 implementation rule for the 
1997 ozone NAAQS (Phase 2 Rule), which includes requirements for PSD 
programs to treat nitrogen oxides (NOx) as a precursor for 
ozone (72 FR 71612, November 29, 2005). EPA proposed approval of the 
August 7, 2008 submittal on January 7, 2009 (74 FR 667), and finalized 
approval on June 29, 2011. EPA therefore approves in full elements 
110(a)(2)(C) and (J) with this action.

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 
PM2.5 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 the infrastructure SIP 
submissions.\5\ The commenters specifically raised concerns involving 
provisions in existing SIPs and with EPA's statements 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 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 new 
source review (NSR)''); and (ii) existing provisions for Prevention of 
Significant Deterioration programs that may be inconsistent with 
current requirements of EPA's ``Final NSR Improvement Rule,'' 67 FR 
80,186 (December 31, 2002), as amended by 72 FR 32,526 (June 13, 2007) 
(``NSR Reform''). In light of the comments, EPA now believes that its 
statements in various proposed actions on infrastructure SIPs with 
respect to these four individual issues should be explained in greater 
depth with respect to these issues.
---------------------------------------------------------------------------

    \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.
---------------------------------------------------------------------------

    EPA intended the statements in the 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 reapproval 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 
reapproval of any existing provisions that relate to these four 
substantive issues.
    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 issue 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, however, we want to explain more fully the Agency's 
reasons for concluding that these four potential substantive issues in 
existing SIPs may be addressed separately.
    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

[[Page 43901]]

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\
---------------------------------------------------------------------------

    \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 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, e.g., ``Rule To Reduce 
Interstate Transport of Fine Particulate Matter and Ozone (Clean Air 
Interstate Rule); Revisions to Acid Rain Program; Revisions to the 
NOX SIP Call; Final Rule,'' 70 FR 25,162 (May 12, 
2005)(defining, among other things, the phrase ``contribute 
significantly to nonattainment'').
---------------------------------------------------------------------------

    Notwithstanding that section 110(a)(2) states 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 SIP. 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\
---------------------------------------------------------------------------

    \8\ See, e.g., Id., 70 FR 25,162, 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 
PM2.5 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 PM2.5 
NAAQS required the deployment of a system of new monitors to measure 
ambient levels of that new indicator species for the new NAAQS.
---------------------------------------------------------------------------

    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 requirement 
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 NAAQS.
    On October 2, 2007, EPA issued guidance making recommendations for 
the infrastructure SIP submissions for both the 1997 8-hour ozone NAAQS 
and the 1997 PM2.5 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

[[Page 43902]]

assistance from EPA Regions.'' \14\ For the one exception to that 
general assumption, however, i.e., how states should proceed with 
respect to the requirements of section 110(a)(2)(G) for the 1997 
PM2.5 NAAQS, EPA gave much more specific recommendations. 
But for other infrastructure SIP submittals, and for certain elements 
of the submittals for the 1997 PM2.5 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 SIP for the NAAQS in question.
---------------------------------------------------------------------------

    \11\ See, ``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,'' from William T. Harnett, 
Director Air Quality Policy Division, to Air Division Directors, 
Regions I-X, dated October 2, 2007 (the ``2007 Guidance''). EPA 
issued comparable guidance for the 2006 PM2.5 NAAQS 
entitled ``Guidance on SIP Elements Required Under Sections 
110(a)(1) and (2) for the 2006 24-Hour Fine Particle 
(PM2.5) 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'').
    \12\ Id., at page 2.
    \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.
---------------------------------------------------------------------------

    Significantly, the 2007 Guidance did not explicitly refer 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, 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 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 
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.
    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 PM2.5 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 SIP is substantially 
inadequate to attain or maintain the NAAQS, to mitigate interstate 
transport, or otherwise to comply with the CAA.\15\ Section 110(k)(6) 
authorizes EPA to correct errors in past actions, such as past 
approvals of SIP submissions.\16\ 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.\17\
---------------------------------------------------------------------------

    \15\ 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,'' 74 FR 21,639 (April 18, 2011).
    \16\ 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 Deterioration 
Provisions Concerning Greenhouse Gas Emitting-Sources in State 
Implementation Plans; Final Rule,'' 75 FR 82,536 (Dec. 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, e.g., 61 FR 38,664 (July 25, 1996) and 62 FR 
34,641 (June 27, 1997) (corrections to American Samoa, Arizona, 
California, Hawaii, and Nevada SIPs); 69 FR 67,062 (November 16, 
2004) (corrections to California SIP); and 74 FR 57,051 (November 3, 
2009) (corrections to Arizona and Nevada SIPs).
    \17\ 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, e.g., 75 FR 42,342 at 42,344 (July 21,2010) 
(proposed disapproval of director's discretion provisions); 76 FR 
4,540 (Jan. 26, 2011) (final disapproval of such provisions).
---------------------------------------------------------------------------

II. Response to Comments

    EPA received two comment letters on June 22, 2011, one from 
WildEarth Guardians (WEG) and the other from Western Resource Advocates 
(WRA), both environmental organizations. The WRA comment letter was 
written on behalf of both WRA and the organization Utah Physicians for 
a Healthy Environment (UPHE). The significant comments made by WRA and 
EPA's responses to those comments are given below in Section (A). The 
significant comments made by WEG and EPA's responses to those comments 
are given below in Section (B).

Section A: WRA Comments and EPA Responses

    Comment No. 1: The commenter stated that the State of Utah must 
strike from its regulations ``any provisions allowing `director's 
discretion' to change unilaterally EPA-approved SIP-based emission 
limits, permitting variances and exempting excess startup, shutdown and 
malfunction emissions from compliance and enforcement provisions.'' The 
commenter further stated that ``definitive EPA action'' on such 
provisions ``cannot come too soon.''
    EPA Response: EPA shares the commenter's concerns that such 
provisions can have adverse impacts on air planning and enforcement, 
and as a result can have an adverse impact on

[[Page 43903]]

protection of public health. As discussed in greater depth in the 
Background section, EPA is not addressing startup, shutdown, and 
malfunction (SSM), variance, or director's discretion provisions in the 
context of this action on 110(a)(2) requirements for the 1997 ozone 
NAAQS. As stated in the NPR, EPA intends to address these issues 
separately at a later date.
    However, with respect to the commenter's concerns about SSM 
provisions, EPA notes that the Agency has already issued a finding of 
substantial inadequacy and called for a SIP revision for Utah's 
``unavoidable breakdown'' rule (76 FR 21639, Apr. 18, 2011). This 
action preceded, was independent of, and was not required for our 
action on section 110(a)(2)(A) for the 1997 ozone NAAQS. EPA considers 
this an important step towards addressing the issue noted by the 
commenter.
    Comment No. 2: The commenter supported EPA efforts to address 
issues concerning the monitoring network for ozone in Utah. In 
particular, the commenter supported EPA's efforts to encourage the 
State to address the monitoring network in the Saint George area, 
specifically by completing its ozone saturation study in 2011, using 
that study to identify maximum concentration locations, and adjusting 
the monitoring network as required by the study. However, the commenter 
also urged EPA to require immediate action from the State to ensure 
adequate monitoring in the Saint George area, and, if necessary, 
immediately implement any controls necessary to bring the area into 
compliance with the ozone NAAQS.
    EPA Response: EPA acknowledges the support for our conditional 
approval, based on Utah's commitment to make improvements with regard 
to monitoring as the commenter described. EPA notes that the State has 
committed to doing so within one year, and that with this data the 
State and EPA can then evaluate what additional actions may be 
necessary based upon better information concerning the ambient air 
quality in the area.
    With respect to the 1997 ozone NAAQS, the data collected in 
southern Utah have not suggested a potential for ozone levels to 
violate that standard. From data collected in Zion National Park (2004-
2010), Saint George (1995-1997), Santa Clara (2008-2010), and Mesquite, 
Nevada (33 miles southwest of Saint George and 13 miles from the Utah 
border), the highest design value recorded was 79 parts per billion 
(ppb) in Zion National Park in 2004-2006. While the current Santa Clara 
monitor has not been shown to be sited to measure maximum concentration 
monitoring, there is no evidence to suggest a maximum concentration 
monitoring site elsewhere would record data in excess of the 1997 ozone 
NAAQS. Utah's commitment to ensuring that a monitor is placed at the 
maximum concentration site will allow the State and EPA to correctly 
assess air quality in the Saint George metropolitan statistical area 
(MSA).
    Comment No. 3: The commenter supported EPA's efforts to regulate 
greenhouse gases.
    EPA Response: EPA presumes that the commenter's support related to 
EPA's efforts to insure that the Utah infrastructure SIP adequately 
addresses PSD permitting requirements with respect to greenhouse gases 
as discussed in the NPR in accordance with the PSD SIP Narrowing Rule. 
As discussed in the background section above, in response to our 
proposal, Utah clarified that its infrastructure certification should 
not be read to rely on the portion of the PSD program for which the PSD 
SIP Narrowing Rule withdrew approval. Therefore, EPA has concluded that 
the current EPA approved Utah SIP is consistent with section 
110(a)(2)(C) for purposes of greenhouse gases.
    Comment No. 4: The commenter supported EPA's efforts to require 
ozone monitoring in Utah's Uinta Basin. However, the commenter urged 
EPA to use existing ozone monitoring data, which the commenter claimed 
``plainly show that air quality in the basin is not in compliance with 
the ozone standard,'' to designate the Uinta Basin as nonattainment for 
ozone.\18\ The commenter also urged EPA to require Utah to install 
monitors in Vernal, Utah.
---------------------------------------------------------------------------

    \18\ The comment does not precisely state which existing ozone 
monitoring data the commenter refers to. For a discussion of other 
monitoring data in the Uinta Basin, see the response to comment 1 in 
section B below.
---------------------------------------------------------------------------

    EPA Response: EPA shares the concerns of the commenters with 
respect to the monitoring network in Utah. However, in this action EPA 
is evaluating the adequacy of the infrastructure SIP of the State with 
respect to the 1997 8-hour ozone NAAQS. EPA has specific regulatory 
requirements at 40 CFR part 58 that provide requirements for the 
ambient air monitoring network required by section 110(a)(2)(B) of the 
Act for these NAAQS.
    As discussed in the response to comment 3 in section B below, 40 
CFR part 58 does not contain requirements for the State to monitor for 
ozone in the Uinta Basin. EPA therefore has no basis in this action to 
disapprove the infrastructure SIP due to the absence of an ozone 
monitor in Vernal. Nonetheless, EPA notes that both Utah Department of 
Environmental Quality (DEQ) and the Ute Indian Tribe of the Uintah and 
Ouray Reservation began ozone monitoring in the Uinta Basin in 2011. 
These monitors should provide data that can be used to evaluate the 
appropriate designation for the Uinta Basin area, once there is 
sufficient data. Promulgation of area designations for a NAAQS is 
outside the scope of this action, the purpose of which is limited to 
review the Utah SIP for compliance with the infrastructure SIP 
requirements of section 110(a)(2) for the 1997 8-hour ozone NAAQS.
    Comment No. 5: The commenter stated that ``Utah's PSD program fails 
to comply'' with the CAA, and therefore encouraged EPA to disapprove 
the State's submission with regards to its PSD program and the 
requirements of section 110(a)(2)(J). Specifically, the commenter 
asserted that the State's PSD program fails to comply with 40 CFR 
70.4(b)(3)(x) with respect to the availability of state judicial review 
for persons who participated in the public process required under 40 
CFR 70.7(h). In essence, the commenter cited rules and statutes 
governing Utah administrative appeal proceedings, including 
administrative appeal of PSD permits issued by the State, and argued 
(for several reasons) that these provide inadequate opportunity for 
members of the public to participate in administrative appeals. The 
commenter linked this to the availability of state judicial review of 
PSD permits by citing a statutory requirement in Utah's Administrative 
Procedure Act requiring parties seeking judicial review to exhaust all 
administrative remedies available.
    EPA Response: In this action, EPA is evaluating the State's PSD 
permit program under sections 110(a)(2)(C) and (J), and, more 
generally, Utah's SIP under section 110(a)(2). The regulatory provision 
that the commenter cited, 40 CFR 70.4(b)(3), and the corresponding 
statutory provision in section 503(b)(6) of the CAA, apply only to 
Title V operating permit programs. In other words, section 503(b)(6) 
and 40 CFR 70.4(b)(3) do not apply to PSD permits. Furthermore, Utah's 
Title V program is not part of the Utah SIP. Therefore, any potential 
deficiency in Utah's Title V program with regards to availability of 
state judicial review is outside the scope of this action on the 
infrastructure SIP, and the comment gives us no basis to

[[Page 43904]]

change our proposed action on section 110(a)(2)(J).\19\
---------------------------------------------------------------------------

    \19\ Although EPA is not assessing the availability of state 
judicial review for PSD permits issued by Utah, as the CAA makes no 
requirements regarding such availability, EPA also notes that the 
comment does not explain, for example, why denial of a petition to 
intervene in a state administrative PSD permit proceeding would not 
exhaust the petitioner's administrative remedies and therefore make 
state judicial review available to the petitioner.
---------------------------------------------------------------------------

    In addition, the comment expressed concerns primarily with a 
version of Utah Administrative Code (UAC) section R305-6-202 that the 
comment describes as effective July, 2011. The commenter did not 
provide a copy of the section showing that it had been adopted. A 
proposal to adopt the version of R305-6-202 for which the comment 
provides concerns was published in the Utah State Bulletin on March 15, 
2011, with a potential effective date of July 1, 2011.\20\ Subsequent 
issues of the Utah State Bulletin (through June 15, 2011) have not 
provided a notice of effective date for the proposal, a requirement 
under section 63G-301-3(12) of the Utah Administrative Procedures Act 
for a rule to become effective. Thus, the rule has only been proposed 
and not adopted, and any deficiencies there may be within it do not 
provide a basis for EPA to change its proposed approval of the current 
Utah infrastructure SIP for the 1997 ozone NAAQS for elements 
110(a)(2)(C) and (J).
---------------------------------------------------------------------------

    \20\ Similarly, a proposed conforming amendment to UAC section 
R307-103 (containing the current administrative procedures for 
adjudicative proceedings under the Utah Air Conservation Act) was 
published May 1, 2011, but no notice of effective date has been 
published. The status of these proposals is confirmed by the Utah 
Division of Administrative Rules Web page, Rules Effective Since 
Last Codification, available at http://www.rules.utah.gov/publicat/codificationsegue.htm (last visited June 29, 2011).
---------------------------------------------------------------------------

Section B: WEG Comments and EPA Responses

    Comment No. 1: The commenter expressed concern that Utah's SIP 
fails ``to attain and maintain the 1997 8-hour ozone NAAQS in the Uinta 
Basin.'' The commenter pointed to existing monitoring data from two 
monitors in the Uinta Basin over two years and part of a third to argue 
that the standard is currently being violated.\21\ The commenter 
asserted that EPA cannot find that Utah's SIP meets section 
110(a)(2)(1) and (2) requirements unless the EPA addresses the high 
ozone levels in the Uinta Basin and uses the resources necessary ``to 
attain and maintain the NAAQS.''
---------------------------------------------------------------------------

    \21\ The monitoring data provided by WEG to support this 
argument is available in the docket for this action.
---------------------------------------------------------------------------

    EPA Response: EPA disagrees with the commenter's view that the 
monitor data asserted by the commenter has a bearing on the action on 
the State's infrastructure SIP submission. First, there are currently 
no nonattainment areas designated in Utah for the 1997 ozone NAAQS. 
Thus, the State is not currently under an obligation to submit a SIP to 
meet the requirements of Part D of title I. More importantly, as 
explained in the NPR, Part D requirements are outside the scope of this 
action. EPA therefore disagrees with the assertion that, as a result of 
the cited monitoring data, EPA cannot approve the Utah infrastructure 
SIP for the 1997 ozone NAAQS.
    Furthermore, EPA notes that data cited by the commenter is also not 
of the type that is needed for making attainment determinations. The 
monitoring data referenced by the commenter was collected by industrial 
entities at non-regulatory monitors located in Indian country, outside 
the jurisdiction of the State of Utah. Furthermore, data collected by 
the National Park Service in Dinosaur National Monument (albeit also 
using a non-regulatory monitoring method) indicate a preliminary design 
value of only 73 ppb for the maximum 3-year average in 2009-2011. This 
data represents the ambient level at a geographic location within the 
Uinta Basin that is available outside Indian country in Utah. Thus, 
there is currently no data from monitoring sites on State jurisdiction 
lands in or near the Uinta Basin showing violations of the 1997 ozone 
standard.
    Comment No. 2: The commenter claims that the State's commitment 
letter to update its ozone monitoring network does not represent a 
commitment that justifies conditional approval, as the letter does not 
commit to ensuring the actual installation of a monitor in the Saint 
George area in accordance with 40 CFR part 58, Appendix D, 4.1(b), and 
other requirements. The commenter also states that EPA did not clearly 
state the timeline by which a conditional approval reverts to a 
disapproval, and requests EPA to clarify this statement.
    EPA Response: EPA disagrees with this comment. The commitment by 
the State is appropriately tailored to require the analysis necessary 
to determine if a monitor should be installed in the Saint George's 
area. The letter acknowledges that the State has not demonstrated that 
the existing Santa Clara monitor represents the maximum concentration 
site in the Saint George core-based statistical area (CBSA) and that 
the Zion monitoring site operated by the National Park Service has 
recorded higher ozone values. The letter commits to completing the 
current saturation study to determine whether the Santa Clara site 
represents the maximum concentration site, and, if the study shows it 
necessary, to relocate the monitor in accordance with the requirements 
of section 4.1 of Appendix D. Of course, if the study is sufficient to 
demonstrate that the existing Santa Clara site meets the requirements 
of Appendix D, then no further action is necessary to comply with 
Appendix D.
    Appendix D requires that Utah operate an ozone monitor in the Saint 
George CBSA, requires that at least one monitor in the Saint George 
CBSA be designed to measure maximum concentration, and that the siting 
of the Saint George monitor(s) be approved by the EPA Regional 
Administrator. EPA's conditional approval requires Utah to comply with 
these requirements within 1 year of the publication of the final rule. 
If the EPA Regional Administrator has not approved the monitor siting 
in the Saint George CBSA within 1 year of publication of the final 
rule, the conditional approval of the Utah infrastructure SIP for 
section 110(a)(2)(B) for the 1997 ozone NAAQS will automatically revert 
to disapproval.
    Comment No. 3: The commenter expressed concern that the ozone 
monitoring sites in the Uinta Basin do not fully comply with 40 CFR 
part 58, specifically the requirement that ``monitors are sited to 
ensure that maximum concentrations are recorded.'' The commenter also 
stated that, in order to meet the requirements of section 110(a)(2)(B), 
EPA must ensure the Utah SIP requires the State to monitor ozone during 
the winter months, particularly in the Uinta Basin. The commenter 
asserted that monitoring should continue during the winter months when 
the highest ambient levels occur.
    EPA Response: EPA disagrees with the commenter's view that the 
current SIP is not approvable under section 110(a)(2)(B), based on the 
monitoring concerns raised by the commenter. The existing Utah ozone 
monitoring network and plan comply with 40 CFR part 58 requirements 
with respect to Uintah, Duchesne and Carbon counties. 40 CFR part 58 
does not currently require ozone monitoring in the Uinta Basin, because 
ozone monitoring is only required in Metropolitan Statistical Areas 
(MSAs). Furthermore, the maximum concentration monitoring requirement 
of Appendix D applies specifically to monitoring in MSAs, defined in 40 
CFR 58.1 as ``a CBSA associated with at least

[[Page 43905]]

one urbanized area of 50,000 population or greater.'' There are no such 
MSAs in Uintah, Duchesne, or Carbon counties.
    With respect to the season during which monitoring is currently 
required, the required ozone monitoring seasons are provided in 
Appendix D, which currently specifies monitoring from May through 
September. EPA published a proposed revision to the ozone monitoring 
season for Utah on July 16, 2009 (74 FR 34525). EPA then published more 
recent data from Utah, Colorado and Kansas relevant to that proposal in 
a Notice of Data Availability on November 10, 2010 (75 FR 60936) and 
solicited comment on the applicability of that data to the required 
monitoring season at that time. If EPA finalizes the proposed revisions 
to the ozone monitoring season for Utah, the monitoring season will be 
extended and EPA anticipates that this would help to address the 
underlying concern of the commenters. At this point, however, Utah 
complies with the existing monitoring season requirements of Appendix 
D.
    Comment No. 4: The commenter states that EPA cannot approve Utah's 
SIP as meeting CAA section 110(a)(2)(L) requirements. Citing 42 U.S.C. 
section 7661a(b)(3)(B)(v) and 40 CFR 70.9(b)(2)(iv), the commenter 
argues that Utah's Title V program does not increase permit fees each 
year in accordance with the Consumer Price Index as required.
    EPA Response: EPA disagrees with this comment. As stated in the 
text of the section, 110(a)(2)(L) is no longer applicable to Title V 
operating permit programs after approval of such programs. As noted in 
the NPR, the Administrator's final approval of Utah's Title V operating 
permit program, including the Title V fee program, became effective on 
July 10, 1995 (60 FR 30192). Therefore, EPA concludes that the Utah 
infrastructure SIP for the 1997 ozone NAAQS meets the requirements of 
section 110(a)(2)(L) with respect to the Title V program.

III. Final Action

    In this action, EPA is approving in full the following section 
110(a)(2) infrastructure elements for Utah for the 1997 ozone NAAQS: 
(A), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M). EPA is 
conditionally approving section 110(a)(2)(B) for the 1997 ozone NAAQS, 
and will fully approve this element if Utah takes the measures detailed 
in the State's May 12, 2011 commitment letter within one year after the 
date of this final action. If, however, Utah does not implement the 
measures specified in its commitment within one year after the date of 
this action, EPA's conditional approval will automatically revert to 
disapproval of the infrastructure SIP for section 110(a)(2)(B) for the 
1997 ozone NAAQS.

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 some state law as meeting Federal requirements 
and disapproves other state law because it does not meet Federal 
requirements; this action 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 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.
    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 Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by September 20, 2011. 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).)
