Approval and Promulgation of State Implementation Plan Revisions;

Infrastructure Requirements for the 1997 8-hour Ozone National Ambient

Air Quality Standards; South Dakota

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

SUMMARY: EPA is approving the State Implementation Plan (SIP) submission from the State of South Dakota to demonstrate that the SIP meets the requirements of the Clean Air Act (CAA) for the National

Ambient Air Quality Standards (NAAQS) promulgated for ozone on July 18, 1997. 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''. The State of South

Dakota

Page 43913

submitted a certification, dated February 1, 2008, that its SIP met these requirements for the 1997 ozone NAAQS; the certification was determined to be complete on March 27, 2008. In addition, EPA is partially approving a June 14, 2010 SIP submittal from the State that revises the State's Prevention of Significant Deterioration (PSD) program.

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 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 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 South Dakota had submitted a complete SIP

(``Infrastructure SIP'') to meet these requirements.

On May 12, 2011, EPA published a notice of proposed rulemaking

(NPR) for the State of South Dakota (76 FR 27622) to act on the State's

Infrastructure SIP for the 1997 ozone NAAQS. Specifically, in the NPR

EPA proposed approval of South Dakota'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 27622) for further explanation regarding the omission of elements 110(a)(2)(D)(i) and 110(a)(2)(I) from the proposal.

EPA proposed to approve element 110(a)(2)(C) for the 1997 ozone

NAAQS in the event that the State clarified (or modified) its February 1, 2008 certification 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 South

Dakota's prevention of significant deterioration (PSD) program to the extent that it applied PSD permitting to greenhouse gas (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 South Dakota'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 February 1, 2008 certification, South Dakota 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 South Dakota

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

Page 43914

consideration the remaining portion of its PSD program submission that would have applied PSD permitting to GHG sources below the Tailoring

Rule thresholds. On May 9, 2011, EPA received a letter from South

Dakota (dated May 5, 2011) 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.\3\

\3\ South Dakota's May 5, 2011 clarification letter is available in the docket for this action.

In the May 12, 2011 NPR, EPA also proposed action on revisions to

Administrative Rules of South Dakota (ARSD) Chapter 74:36:09 (PSD) from

South Dakota's June 14, 2010 SIP submission. The revisions to the

State's PSD program updated the date of incorporation by reference of the Federal rules at 40 CFR 52.21 to July 1, 2009. EPA proposed to approve this revision with the following exception. Consistent with the

Tailoring Rule and the SIP PSD Narrowing Rule, EPA proposed to disapprove the revision of ARSD 74:36:09 in the June 14, 2010 submission to the extent that the revision applies PSD permitting to

GHG emissions increases from GHG-emitting sources below Tailoring Rule thresholds.

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.\4\ 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.

\4\ 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

PM2.5NAAQS 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

Page 43915

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.\5\ 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.\6\

\5\ 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.

\6\ 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

NOxSIP 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).\7\ 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.\8\ 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.\9\

\7\ 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)).

\8\ 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 PM2.5NAAQS. 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

PM2.5National 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.

\9\ 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.\10\ 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.'' \11\ 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

Page 43916

required elements.'' \12\ 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.'' \13\ 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.

\10\ 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'').

\11\ Id., at page 2.

\12\ Id., at attachment A, page 1.

\13\ 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.\14\ Section 110(k)(6) authorizes EPA to correct errors in past actions, such as past approvals of SIP submissions.\15\ 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.\16\

\14\ 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).

\15\ 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).

\16\ 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 did not receive any comments on the May 12, 2011, NPR (76 FR 27622).

III. Final Action

In this action, EPA is approving the following section 110(a)(2) infrastructure elements for South Dakota for the 1997 ozone NAAQS: (A),

(B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), (M). EPA is also approving the portion of South Dakota's June 14, 2010 SIP submission that revises South Dakota's PSD program to incorporate by reference the

Federal program at 40 CFR 52.21 as of July 1, 2009, except to the extent that revision applies PSD permitting to GHG emissions increases from GHG-emitting sources below the thresholds set out in the Tailoring

Rule, 75 FR 31514.

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 USC 7410(k), 40 CFR 52.02(a)). Thus, in reviewing SIP submissions,

Page 43917

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:

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).)
