I. Background

    On March 30, 2011 (76 FR 17585), EPA published a proposed 
rulemaking for the State of Missouri. This rulemaking proposed approval 
of Missouri's submittal dated February 27, 2007, as meeting the 
relevant and applicable requirements of CAA sections 110(a)(1) and (2) 
necessary to implement, maintain, and enforce the 1997 NAAQS.

II. Summary of Relevant Submissions

    The above referenced submittal addresses the infrastructure 
elements specified in CAA sections 110(a)(1) and (2). This submittal 
refers to the implementation, maintenance and enforcement of the 1997 
8-hour ozone NAAQS. The rationale supporting EPA's proposed action is 
explained in the proposal and EPA incorporates by reference the 
rationale in the proposal as supplemented by this rule, as its 
rationale for the final rule. No public comments were received on the 
proposed rulemaking.

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 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.\1\ 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 NSR''); 
and (ii) existing provisions for Prevention of Significant 
Deterioration (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 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.
---------------------------------------------------------------------------

    \1\ 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 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.
    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

[[Page 40621]]

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, new source review 
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.\2\ 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.\3\
---------------------------------------------------------------------------

    \2\ 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.
    \3\ 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, 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 25162 (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).\4\ 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.\5\ 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 plan. 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.\6\
---------------------------------------------------------------------------

    \4\ See, e.g., 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)).
    \5\ 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.
    \6\ 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

[[Page 40622]]

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.\7\ 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.'' \8\ 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.'' \9\ 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.'' \10\ 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 State's 
implementation plan for the NAAQS in question.
---------------------------------------------------------------------------

    \7\ 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'').
    \8\ Id., at page 2.
    \9\ Id., at attachment A, page 1.
    \10\ 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 State's implementation 
plan is substantially inadequate to attain or maintain the NAAQS, to 
mitigate interstate transport, or otherwise to comply with the CAA.\11\ 
Section 110(k)(6) authorizes EPA to correct errors in past actions, 
such as past approvals of SIP submissions.\12\ 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

[[Page 40623]]

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.\13\
---------------------------------------------------------------------------

    \11\ 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 21639 (April 18, 2011).
    \12\ 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 82536 (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 38664 (July 25, 1996) and 62 FR 
34641 (June 27, 1997) (corrections to American Samoa, Arizona, 
California, Hawaii, and Nevada SIPs); 69 FR 67062 (November 16, 
2004) (corrections to California SIP); and 74 FR 57051 (November 3, 
2009) (corrections to Arizona and Nevada SIPs).
    \13\ 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 42342 at 42344 (July 21, 
2010)(proposed disapproval of director's discretion provisions); 76 
FR 4540 (January 26, 2011)(final disapproval of such provisions).
---------------------------------------------------------------------------

IV. Final Action

    EPA is taking final action to approve Missouri's submittal that 
provides the basic program elements to meet the applicable requirements 
in CAA sections 110(a)(2)(A),(B),(C), 
(D)(ii),(E),(F),(G),(H),(J),(K),(L), and (M) necessary to implement, 
maintain, and enforce the 1997 8-hour ozone NAAQS.
    As explained in the proposed rulemaking, this action does not 
address the requirements of section 110(a)(2)(D)(i) for the 1997 8-hour 
ozone NAAQS, because it has already been addressed in a separate 
rulemaking. See 72 FR 25975. The scope of this action is further 
discussed in section III, above.

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting federal requirements and 
does not impose additional requirements beyond those imposed by State 
law. For those reasons, 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 amended by 
the Small Business Regulatory Enforcement Fairness Act of 1996, 
generally provides that before a rule may take effect, the agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of the Congress and to the Comptroller 
General of the United States. EPA will submit a report containing this 
action and other required information to the U.S. Senate, the U.S. 
House of Representatives, and the Comptroller General of the United 
States prior to publication of the rule in the Federal Register. A 
major rule cannot take effect until 60 days after it is published in 
the Federal Register. This action is not a ``major rule'' as defined by 
5 U.S.C. 804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by September 9, 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).)
