**SUPPLEMENTARY INFORMATION :**  For further information, please see the direct final action, of the same title,

which is located in the Rules section of

this Federal Register . The EPA is correcting an error made in a final rule (79 FR 33438, June 11, 2014) by adding

the conversion factor from tons to pounds of SO 2 to 40 CFR 52.2502(b)(1)(i). The EPA is making this correction without prior proposal

because the EPA views this as a

noncontroversial revision and anticipates no adverse comments. A

detailed rationale for the action is set forth in the preamble to the direct final

rule. If the EPA receives no adverse comments, the EPA will not take further action on this proposed rule.

If the EPA receives adverse comments, the EPA will withdraw the

direct final rule and it will not take effect. The EPA will address all public comments in a subsequent final rule based on this proposed rule. The EPA

will not institute a second comment period on this action. Any parties interested in commenting on this action

should do so at this time. Please note

that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, the EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve in part and disapprove in part, the May 29, 2012, and July 26, 2012, State Implementation Plan (SIP) submissions, provided by the Mississippi Department of Environmental Quality (MDEQ) for inclusion into the Mississippi SIP. This proposal pertains to the Clean Air Act (CAA or the Act) infrastructure requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ‘‘infrastructure’’ SIP. MDEQ certified that the Mississippi SIP contains provisions that ensure the 2008 8-hour ozone NAAQS is implemented, enforced, and maintained in Mississippi (hereafter referred to as an ‘‘infrastructure SIP submissions’’). With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, interstate transport, visibility protection requirements and the state board majority requirements respecting significant portion of income, EPA is proposing to determine that Mississippi’s infrastructure SIP submissions, provided to EPA on May 29, 2012, and July 26, 2012, address the required infrastructure elements for the 2008 8-hour ozone NAAQS.

1 In these infrastructure SIP submissions States generally certify evidence of compliance with sections 110(a)(1) and (2) of the CAA through a combination of state regulations and statutes, someof which have been incorporated into the federallyapproved SIP. In addition, certain federallyapproved, non-SIP regulations may also be appropriate for demonstrating compliance with sections 110(a)(1) and (2). Throughout this rulemaking, unless otherwise indicated, the term ‘‘Air Pollution Control (APC)’’ or ‘‘Section APC–S– X’’ indicates that the cited regulation has been approved into Mississippi’s federally-approved SIP. The term ‘‘Mississippi Code’’ indicates cited Mississippi state statutes, which are not a part of the SIP unless otherwise indicated. Additionally, since the time of Mississippi’s infrastructure SIP submissions for the 2008 8-hour NAAQS, the state’s implementation plan and statutes and have been recodified. In its original infrastructure SIP submission, MDEQ refers to Mississippi Code Title

49 as ‘‘Appendix A–8.’’ However, Mississippi supplemented its original infrastructure SIP submission following this recodification, and as such, updated the Mississippi Code reference to ‘‘Appendix A–9’’ to reflect the most current codification. Accordingly, EPA utilizes the ‘‘Appendix A–9’’ reference throughout today’s rulemaking. 2 Two elements identified in section 110(a)(2) are not governed by the three year submission deadline of section 110(a)(1) because SIPs incorporating necessary local nonattainment area controls are not due within three years after promulgation of a new or revised NAAQS, but rather due at the time the nonattainment area plan requirements are due pursuant to section 172. These requirements are: (1) Submissions required by section 110(a)(2)(C) to the extent that subsection refers to a permit program as required in part D Title I of the CAA; and (2) submissions required by section 110(a)(2)(I) which pertain to the nonattainment planning requirements of part D, Title I of the CAA. Today’s proposed rulemaking does not address infrastructure elements related to section 110(a)(2)(I) or the nonattainment planning requirements of 110(a)(2)(C).

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

4 As mentioned above, this element is not relevant to today’s proposed rulemaking. Management Division, U.S. Environmental Protection Agency, Region 4, 61 Forsyth Street SW., Atlanta, Georgia 30303–8960. The telephone number is (404) 562–9140.

Infrastructure SIP Submissions? IV. What is EPA’s Analysis of How Mississippi Addressed the Elements of Sections 110(a)(1) and (2)

I. Background and Overview

On March 27, 2008, EPA promulgated a revised NAAQS for ozone based on 8- hour average concentrations. EPA

revised the level of the 8-hour ozone NAAQS to 0.075 parts per million. See

77 FR 16436. Pursuant to section 110(a)(1) of the CAA, states are required to submit SIPs meeting the applicable requirements of section 110(a)(2) within three years after promulgation of a new or revised NAAQS or within such shorter period as EPA may prescribe. Section 110(a)(2) requires states to

address basic SIP elements such as requirements for monitoring, basic program requirements and legal authority that are designed to assure

attainment and maintenance of the NAAQS. States were required to submit

such SIPs for the 2008 8-hour ozone NAAQS to EPA no later than March

2011. 1 Today’s action is proposing to approve Mississippi’s infrastructure SIP submissions for the applicable requirements of the 2008 8-hour ozone NAAQS, with the exception of the PSD permitting requirements for major sources of section 110(a)(2)(C) and (J), the interstate transport requirements of section 110(a)(2)(D)(i)(I) and (II) (prongs 1 through 4), the state board majority requirements respecting significant portion of income of section 110(a)(2)(E)(ii), and the visibility requirements of section 110(a)(2)(J). With respect to Mississippi’s

infrastructure SIP submissions related to the provisions pertaining to the PSD permitting requirements for major sources of sections 110(a)(2)(C) and (J), the interstate transport requirements of section 110(a)(2)(D)(i)(I) and (II), and the visibility requirements of 110(a)(2)(J), EPA is not proposing any action today regarding these requirements. EPA will act on these portions of the submissions in a separate action. With respect to Mississippi’s infrastructure SIP submissions related to the majority requirements respecting significant portion of income of 110(a)(2)(E)(ii), EPA is proposing to disapprove this portion of Mississippi’s submissions in today’s rulemaking. For the aspects of Mississippi’s submittals proposed for approval today, EPA notes that the Agency is not approving any specific rule, but rather proposing that Mississippi’s already approved SIP meets certain CAA requirements.

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

Section 110(a) of the CAA requires states to submit SIPs to provide for the implementation, maintenance, and

enforcement of a new or revised NAAQS within three years following the promulgation of such NAAQS, or within such shorter period as EPA may prescribe. Section 110(a) imposes the obligation upon states to make a SIP

submission to EPA for a new or revised NAAQS, but the contents of that submission may vary depending upon

the facts and circumstances. In particular, the data and analytical tools available at the time the state develops

and submits the SIP for a new or revised NAAQS affects the content of the

submission. The contents of such SIP submissions may also vary depending upon what provisions the state’s existing SIP already contains. In the case of the 2008 8-hour ozone NAAQS, states typically have met the basic program elements required in section 110(a)(2) through earlier SIP

submissions in connection with the 1997 8-hour ozone NAAQS. More specifically, section 110(a)(1) provides the procedural and timing requirements for SIPs. Section 110(a)(2) lists specific elements that states must

meet for ‘‘infrastructure’’ SIP requirements related to a newly established or revised NAAQS. As mentioned above, these requirements

include basic SIP elements such as requirements for monitoring, basic program requirements and legal authority that are designed to assure

attainment and maintenance of the NAAQS. The general requirements that are the subject of EPA’s infrastructure SIP rulemakings are summarized below and in EPA’s September 13, 2013,

memorandum entitled ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2).’’ 2

5 For example: Section 110(a)(2)(E)(i) 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 SIP-approved program to address certain sources as required by part C of title I of the CAA; and section 110(a)(2)(G) provides that states must have legal authority to address emergencies as well as contingency plans that are triggered in the event of such emergencies.

6 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 NO X SIP Call; Final Rule,’’ 70 FR 25162, at 25163–65 (May 12, 2005) (explaining relationship between timing requirement of section 110(a)(2)(D) versus section 110(a)(2)(I)).

7 EPA notes that this ambiguity within section 110(a)(2) is heightened by the fact that various subparts of part D set specific dates for submission of certain types of SIP submissions in designated nonattainment areas for various pollutants. Note,

e.g., that section 182(a)(1) provides specific dates

for submission of emissions inventories for the ozone NAAQS. Some of these specific dates are necessarily later than three years after promulgation of the new or revised NAAQS. 8 See, e.g., ‘‘Approval and Promulgation of Implementation Plans; New Mexico; Revisions to the New Source Review (NSR) State Implementation Plan (SIP); Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) Permitting,’’ 78 FR 4339 (January 22, 2013) (EPA’s final action approving the structural PSD elements of the New Mexico SIP submitted by the State separately to meet the requirements of EPA’s 2008 PM 2.5 NSR rule), and ‘‘Approval and Promulgation of Air Quality Implementation Plans; New Mexico; Infrastructure and Interstate Transport Requirements for the 2006 PM 2.5 NAAQS,’’ (78 FR 4337) (January 22, 2013) (EPA’s final action on the

infrastructure SIP for the 2006 PM 2.5 NAAQS).

9 On December 14, 2007, the State of Tennessee, through the Tennessee Department of Environment
and Conservation, made a SIP revision to EPA demonstrating that the State meets the requirements of sections 110(a)(1) and (2). EPA proposed action for infrastructure SIP elements (C) and (J) on January 23, 2012 (77 FR 3213) and took final action on March 14, 2012 (77 FR 14976). On April 16, 2012 (77 FR 22533) and July 23, 2012 (77 FR 42997), EPA took separate proposed and final actions on all other section 110(a)(2) infrastructure
SIP elements of Tennessee’s December 14, 2007

submittal. • 110(a)(2)(L): Permitting fees

• 110(a)(2)(M): Consultation and Participation by Affected Local Entities

III. What is EPA’s approach to the

review of infrastructure SIP

submissions?

EPA is acting upon the SIP submissions from Mississippi that address the infrastructure requirements of CAA sections 110(a)(1) and 110(a)(2) for the 2008 8-hour ozone NAAQS. The requirement for states to make a SIP submission of this type arises out of CAA section 110(a)(1). Pursuant to section 110(a)(1), states must make SIP submissions ‘‘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 these SIP submissions are to provide for the ‘‘implementation, maintenance, and enforcement’’ of such NAAQS. The statute directly imposes on states the duty to make these SIP submissions, and the requirement to make the submissions is not conditioned upon EPA’s taking any action other than promulgating a new or revised NAAQS. Section 110(a)(2) includes a list of specific elements that ‘‘[e]ach such plan’’ submission must address.

EPA has historically referred to these SIP submissions made for the purpose of satisfying the requirements of CAA sections 110(a)(1) and 110(a)(2) as

‘‘infrastructure SIP’’ submissions. Although the term ‘‘infrastructure SIP’’ does not appear in the CAA, EPA uses the term to distinguish this particular type of SIP submission from submissions that are intended to satisfy other SIP requirements under the CAA,

such as ‘‘nonattainment SIP’’ or ‘‘attainment plan SIP’’ submissions to address the nonattainment planning requirements of part D of title I of the CAA, ‘‘regional haze SIP’’ submissions required by EPA rule to address the visibility protection requirements of CAA section 169A, and nonattainment new source review permit program submissions to address the permit requirements of CAA, title I, part D.

Section 110(a)(1) addresses the timing and general requirements for infrastructure SIP submissions, and section 110(a)(2) provides more details concerning the required contents of these submissions. 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 program provisions, and some of which pertain to requirements for both authority and substantive program provisions. 5 EPA therefore believes that while the timing requirement in section 110(a)(1) is unambiguous, some of the other statutory provisions are ambiguous. In particular, EPA believes that the list of required elements for infrastructure SIP submissions provided in section 110(a)(2) contains ambiguities concerning what is required for

inclusion in an infrastructure SIP

submission.

The following examples of ambiguities illustrate the need for EPA to interpret some section 110(a)(1) and section 110(a)(2) requirements with respect to infrastructure SIP submissions for a given new or revised NAAQS. One example of ambiguity is that section 110(a)(2) requires that

‘‘each’’ SIP submission must meet the list of requirements therein, while EPA has long noted that this literal reading of the statute is internally inconsistent

and would create a conflict with the nonattainment provisions in part D of title I of the Act, which specifically

address nonattainment SIP requirements. 6 Section 110(a)(2)(I) pertains to nonattainment SIP requirements and part D addresses when attainment plan SIP submissions

to address nonattainment area requirements are due. For example, section 172(b) requires EPA to establish a schedule for submission of such plans for certain pollutants when the Administrator promulgates the designation of an area as nonattainment, and section 107(d)(1)(B) allows up to two years, or in some cases three years, for such designations to be promulgated. 7 This ambiguity illustrates that rather than apply all the stated requirements of section 110(a)(2) in a strict literal sense, EPA must determine which provisions of section 110(a)(2) are applicable for a particular

infrastructure SIP submission.

Another example of ambiguity within sections 110(a)(1) and 110(a)(2) with respect to infrastructure SIPs pertains to

whether states must meet all of the infrastructure SIP requirements in a single SIP submission, and whether EPA must act upon such SIP submission in a single action. Although section 110(a)(1) directs states to submit ‘‘a plan’’ to meet these requirements, EPA interprets the CAA to allow states to make multiple SIP submissions separately addressing infrastructure SIP elements for the same NAAQS. If states elect to make such multiple SIP

submissions to meet the infrastructure SIP requirements, EPA can elect to act on such submissions either individually or in a larger combined action. 8 Similarly, EPA interprets the CAA to

allow it to take action on the individual parts of one larger, comprehensive

infrastructure SIP submission for a given NAAQS without concurrent

action on the entire submission. For example, EPA has sometimes elected to

act at different times on various

elements and sub-elements of the same

infrastructure SIP submission. 9

Ambiguities within sections 110(a)(1) and 110(a)(2) may also arise with respect to infrastructure SIP submission requirements for different NAAQS. Thus, 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.

The states’ attendant infrastructure SIP submissions for each NAAQS therefore could be different. For example, the monitoring requirements that a state


### 69790 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

10 For example, implementation of the 1997 PM 2.5 NAAQS required the deployment of a system of

new monitors to measure ambient levels of that new indicator species for the new NAAQS. 11 EPA notes, however, that nothing in the CAA requires EPA to provide guidance or to promulgate regulations for infrastructure SIP submissions. The CAA directly applies to states and requires the
submission of infrastructure SIP submissions, regardless of whether or not EPA provides guidance or regulations pertaining to such submissions. EPA elects to issue such guidance in order to assist states, as appropriate.

12 ‘‘Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2),’’ Memorandum from Stephen D. Page, September 13,

2013.

13 EPA’s September 13, 2013, guidance did not make recommendations with respect to

infrastructure SIP submissions to address section 110(a)(2)(D)(i)(I). EPA issued the guidance shortly after the U.S. Supreme Court agreed to review the

D.C. Circuit decision in EME Homer City, 696 F.3d7 (D.C. Cir. 2012) which had interpreted the requirements of section 110(a)(2)(D)(i)(I). In light of the uncertainty created by ongoing litigation, EPA elected not to provide additional guidance on the requirements of section 110(a)(2)(D)(i)(I) at that time. As the guidance is neither binding nor required by statute, whether EPA elects to provide guidance on a particular section has no impact on a state’s CAA obligations. might need to meet in its infrastructure SIP submission for purposes of section 110(a)(2)(B) could be very different for different pollutants because the content and scope of a state’s infrastructure SIP submission to meet this element might be very different for an entirely new NAAQS than for a minor revision to an existing NAAQS. 10

EPA notes that interpretation of section 110(a)(2) is also necessary when EPA reviews other types of SIP submissions required under the CAA. Therefore, as with infrastructure SIP submissions, EPA also has to identify and interpret the relevant elements of section 110(a)(2) that logically apply to these other types of SIP submissions. For example, section 172(c)(7) requires that attainment plan SIP submissions required by part D have to meet the ‘‘applicable requirements’’ of section 110(a)(2). Thus, for example, attainment plan SIP submissions must meet the requirements of section 110(a)(2)(A) regarding enforceable emission limits

and control measures and section 110(a)(2)(E)(i) regarding air agency resources and authority. By contrast, it is clear that attainment plan SIP submissions required by part D would not need to meet the portion of section 110(a)(2)(C) that pertains to the PSD program required in part C of title I of the CAA, because PSD does not apply to a pollutant for which an area is designated nonattainment and thus subject to part D planning requirements. As this example illustrates, each type of SIP submission may implicate some elements of section 110(a)(2) but not

others.

Given the potential for ambiguity in some of the statutory language of section 110(a)(1) and section 110(a)(2), EPA believes that it is appropriate to interpret the ambiguous portions of section 110(a)(1) and section 110(a)(2) in the context of acting on a particular SIP submission. In other words, EPA assumes that Congress could not have intended that each and every SIP submission, regardless of the NAAQS in question or the history of SIP development for the relevant pollutant, would meet each of the requirements, or meet each of them in the same way. Therefore, EPA has adopted an approach under which it reviews infrastructure SIP submissions against the list of elements in section 110(a)(2), but only to the extent each element applies for that particular NAAQS. Historically, EPA has elected to use guidance documents to make

recommendations to states for infrastructure SIPs, in some cases conveying needed interpretations on newly arising issues and in some cases conveying interpretations that have already been developed and applied to

individual SIP submissions for particular elements. 11 EPA most recently issued guidance for infrastructure SIPs on September 13, 2013 (2013 Guidance). 12 EPA developedthis document to provide states with upto-date guidance for infrastructure SIPs for any new or revised NAAQS. Within this guidance, EPA describes the duty of

states to make infrastructure SIP

submissions to meet basic structural SIP requirements within three years of promulgation of a new or revised NAAQS. EPA also made recommendations about many specific subsections of section 110(a)(2) that are

relevant in the context of infrastructure

SIP submissions. 13 The guidance also discusses the substantively important issues that are germane to certain subsections of section 110(a)(2). Significantly, EPA interprets sections 110(a)(1) and 110(a)(2) such that

infrastructure SIP submissions need to

address certain issues and need not address others. Accordingly, EPA

reviews each infrastructure SIP submission for compliance with the applicable statutory provisions of section 110(a)(2), as appropriate.

As an example, section 110(a)(2)(E)(ii) is a required element of section 110(a)(2) for infrastructure SIP submissions. Under this element, a state must meet the substantive requirements of section 128, which pertain to state boards that approve permits or

enforcement orders and heads of executive agencies with similar powers. Thus, EPA reviews infrastructure SIP

submissions to ensure that the state’s implementation plan appropriately addresses the requirements of section 110(a)(2)(E)(ii) and section 128. The 2013 Guidance explains EPA’s interpretation that there may be a variety of ways by which states can appropriately address these substantive statutory requirements, depending on

the structure of an individual state’s permitting or enforcement program ( e.g., whether permits and enforcement orders are approved by a multi-member board or by a head of an executive agency). However they are addressed by the state, the substantive requirements of section 128 are necessarily included

in EPA’s evaluation of infrastructure SIP

submissions because section 110(a)(2)(E)(ii) explicitly requires that the state satisfy the provisions of section

128.

As another example, EPA’s review of

infrastructure SIP submissions with respect to the PSD program requirements in sections 110(a)(2)(C), (D)(i)(II), and (J) focuses upon the structural PSD program requirements contained in part C and EPA’s PSD regulations. Structural PSD program requirements include provisions necessary for the PSD program to address all regulated sources and NSR pollutants. By contrast, structural PSD program requirements do not include provisions that are not required under EPA’s regulations at 40 CFR 51.166 but are merely available as an option for the state, such as the option to provide grandfathering of complete permit applications with respect to the 2012

PM 2.5 NAAQS. Accordingly, the latter optional provisions are types of provisions EPA considers irrelevant in

the context of an infrastructure SIP

action.

For other section 110(a)(2) elements, however, EPA’s review of a state’s

infrastructure SIP submission focuses on assuring that the state’s SIP meets basic structural requirements. For example, section 110(a)(2)(C) includes, among other things, the requirement that states have a program to regulate minor new sources. Thus, EPA

evaluates whether the state has an EPAapproved minor new source review program and whether the program addresses the pollutants relevant to that NAAQS. In the context of acting on an infrastructure SIP submission, however, EPA does not think it is necessary to conduct a review of each and every provision of a state’s existing minor source program ( i.e., already in the


### 69791 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

14 By contrast, EPA notes that if a state were to include a new provision in an infrastructure SIP submission that contained a legal deficiency, such as a new exemption for excess emissions during
SSM events, then EPA would need to evaluate that provision for compliance against the rubric of applicable CAA requirements in the context of the

action on the infrastructure SIP. 15 For example, EPA issued a SIP call to Utah to address specific existing SIP deficiencies related to the treatment of excess emissions during SSM events. See ‘‘Finding of Substantial Inadequacy of Implementation Plan; Call for Utah State Implementation Plan Revisions,’’ 74 FR 21639 (April 18, 2011).

16 EPA has used 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 (December 30, 2010). EPA has previously used its authority under CAA section 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).

17 See, e.g., EPA’s disapproval of 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 (Jan. 26, 2011) (final disapproval of such provisions).

18 Mississippi Code Title 49 is referenced in the State’s infrastructure SIP submissions as ‘‘Appendix
A–9.’’ As discussed above, unless otherwise indicated herein, portions of the Mississippi Code referenced in this proposal are not incorporated

into the SIP. existing SIP) for compliance with the requirements of the CAA and EPA’s regulations that pertain to such

programs.

With respect to certain other issues,

EPA does not believe that an action on

a state’s infrastructure SIP submission is necessarily the appropriate type of action in which to address possible deficiencies in a state’s existing SIP. These issues include: (i) Existing provisions related to excess emissions from sources during periods of startup, shutdown, or malfunction that may be contrary to the CAA and EPA’s policies addressing such excess emissions (‘‘SSM’’); (ii) existing provisions related

to ‘‘director’s variance’’ or ‘‘director’s discretion’’ that may be contrary to the CAA because they purport to allow revisions to SIP-approved emissions limits while limiting public process or not requiring further approval by EPA; and (iii) existing provisions for PSD programs that may be inconsistent with current requirements of EPA’s ‘‘Final NSR Improvement Rule,’’ 67 FR 80186 (December 31, 2002), as amended by 72 FR 32526 (June 13, 2007) (‘‘NSR Reform’’). Thus, EPA believes it may approve an infrastructure SIP submission without scrutinizing the totality of the existing SIP for such potentially deficient provisions and may approve the submission even if it is aware of such existing provisions. 14 It is important to note that EPA’s approval of

a state’s infrastructure SIP submission should not be construed as explicit or implicit re-approval of any existing potentially deficient provisions that relate to the three specific issues just

described.

EPA’s approach to review of

infrastructure SIP submissions is to identify the CAA requirements that are logically applicable to that submission. EPA believes that this approach to the review of a particular infrastructure SIP submission is appropriate, because it

would not be reasonable to read the general requirements of section 110(a)(1) and the list of elements in 110(a)(2) as requiring review of each and every provision of a state’s existing SIP against all requirements in the CAA and EPA regulations 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. These provisions, 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 evaluates adequacy of the infrastructure

SIP submission. EPA believes that a better approach is for states and EPA to

focus attention on those elements of section 110(a)(2) of the CAA most likely to warrant a specific SIP revision due to the promulgation of a new or revised NAAQS or other factors.

For example, EPA’s 2013 Guidance gives simpler recommendations with respect to carbon monoxide than other NAAQS pollutants to meet the visibility requirements of section 110(a)(2)(D)(i)(II), because carbon monoxide does not affect visibility. As a result, an infrastructure SIP submission for any future new or revised NAAQS for carbon monoxide need only state this fact in order to address the visibility prong of section 110(a)(2)(D)(i)(II).

Finally, EPA believes that its approach with respect to infrastructure SIP requirements is based on a reasonable reading of sections 110(a)(1) and 110(a)(2) because the CAA provides

other avenues and mechanisms to address specific substantive deficiencies in existing SIPs. These other statutory tools allow EPA to take appropriately tailored action, depending upon the nature and severity of the alleged SIP deficiency. Section 110(k)(5) authorizes

EPA to issue a ‘‘SIP call’’ whenever the Agency determines that a state’s SIP is substantially inadequate to attain or maintain the NAAQS, to mitigate interstate transport, or to otherwise 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 a state’s infrastructure SIP submission is not the appropriate time and place to address all potential existing SIP deficiencies does not preclude EPA’s subsequent reliance on provisions in section 110(a)(2) as part of

the basis for action to correct those deficiencies 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 an infrastructure SIP submission, EPA believes that section 110(a)(2)(A) may be among the statutory bases that EPA relies upon in the course of addressing such deficiency in a subsequent

action. 17

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

Mississippi’s infrastructure SIP submissions address the provisions of sections 110(a)(1) and (2) as described

below.

1. 110(a)(2)(A): Emission limits and

other control measures: Mississippi’s infrastructure SIP submissions provide an overview of the provisions of the Mississippi Air Pollution Control (APC) regulations relevant to air quality

control. Sections APC–S–1—Air Emission Regulations for the Prevention, Abatement, and Control of Air
Contaminants, and APC–S–3— Regulations for the Prevention of Air Pollution Emergency Episodes, and Mississippi Code Title 49, Section 49– 17–17(h) (Appendix A–9), 18 authorize MDEQ to adopt, modify, or repeal ambient air quality standards and

emissions standards for the control of air pollution, including those necessary to obtain EPA approval under section

110 of the CAA. EPA has made the preliminary determination that the provisions contained in these regulations and Mississippi’s practices


### 69792 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

19 On February 22, 2013, EPA published a proposed action in the Federal Register entitled, ‘‘State Implementation Plans: Response to Petition for Rulemaking; Findings of Substantial Inadequacy; and SIP Calls to Amend Provisions Applying to Excess Emissions During Periods of Startup, Shutdown, and Malfunction; Proposed

Rule.’’ 78 FR 12459. 20 On occasion, proposed changes to the monitoring network are evaluated outside of the network plan approval process in accordance with 40 CFR part 58. are adequate to protect the 2008 8-hour ozone NAAQS in the State.

In this action, EPA is not proposing to approve or disapprove any existing State provisions with regard to excess emissions during SSM of operations at a facility. EPA believes that a number of states have SSM provisions which are contrary to the CAA and existing EPA guidance, ‘‘State Implementation Plans: Policy Regarding Excess Emissions During Malfunctions, Startup, and Shutdown’’ (September 20, 1999), and the Agency plans to address such state regulations in a separate action. 19 In the meantime, EPA encourages any state having a deficient SSM provision to take steps to correct it as soon as possible.

Additionally, in this action, EPA is not proposing to approve or disapprove any existing State rules with regard to

director’s discretion or variance provisions. EPA believes that a number of states have such provisions which are contrary to the CAA and existing EPA guidance (52 FR 45109 (November 24, 1987)), and the Agency plans to take

action in the future to address such state regulations. In the meantime, EPA encourages any state having a director’s discretion or variance provision which is contrary to the CAA and EPA guidance to take steps to correct the deficiency as soon as possible.

2. 110(a)(2)(B): Ambient air quality monitoring/data system: SIPs are required to provide for the establishment and operation of ambient air quality monitors, the compilation and analysis of ambient air quality data,

and the submission of these data to EPA upon request. Section APC–S–1—Air Emission Regulations for the Prevention, Abatement, and Control of Air

Contaminants and Mississippi Code Title 49, Section 49–17–17(g), provide MDEQ with the authority to collect and disseminate information relating to air quality and pollution and the prevention, control, supervision, and abatement thereof. Annually, States develop and submit to EPA for approval statewide ambient monitoring network plans consistent with the requirements of 40 CFR parts 50, 53, and 58. The annual network plan involves an evaluation of any proposed changes to the monitoring network, includes the annual ambient monitoring network design plan and a certified evaluation of the agency’s ambient monitors and auxiliary support equipment. 20 On June 26, 2013, Mississippi submitted its monitoring network plan to EPA, which was approved by EPA on November 22, 2013. Mississippi’s approved monitoring network plan can be

accessed at www.regulations.gov using

Docket ID No. EPA–R04–OAR–2012– 0698. EPA has made the preliminary determination that Mississippi’s SIP and practices are adequate for the ambient air quality monitoring and data system requirements related to the 2008 8-hour ozone NAAQS.

3. 110(a)(2)(C): Program for enforcement of control measures including review of proposed new

sources: In this action, EPA is proposing to approve Mississippi’s infrastructure

SIP submissions for the 2008 8-hour ozone NAAQS with respect to the general requirement in section 110(a)(2)(C) to include a program in the SIP that regulates new and modified

sources of emissions that contribute to

ozone concentrations and the enforcement of oxides of nitrogen (NO X) and volatile organic compounds (VOCs)

emission limits to assist in the protection of air quality in
nonattainment, attainment or

unclassifiable areas. To meet this obligation, Mississippi cited Sections
APC–S–5, Mississippi Regulations for the Prevention of Significant Deterioration of Air Quality and APC–
S–2, Permit Regulation for the Construction and/or Operation of Air Emissions Equipment, both of which pertain to the construction of any new major stationary source or any project at an existing major stationary source in an area designated as nonattainment,

attainment or unclassifiable.

Enforcement: MDEQ’s abovedescribed, SIP-approved regulations provide for enforcement of VOC and

NO X emission limits and control measures and construction permitting for new or modified stationary sources.

Preconstruction PSD Permitting for Major Sources: With respect to Mississippi’s infrastructure SIP

submissions related to the preconstruction PSD permitting requirements for major sources of section 110(a)(2)(C), EPA is not proposing any action today regarding these requirements and instead will act on this portion of the submissions in a separate action.

Regulation of minor sources and modifications: Section 110(a)(2)(C) also requires the SIP to include provisions that govern the minor source preconstruction program that regulates

emissions of the 2008 8-hour ozone NAAQS. Mississippi has a SIP-approved minor NSR permitting program at APC–
S–2, I. D—Permitting Requirements that regulates the preconstruction permitting

of modifications and construction of minor stationary sources.

EPA has made the preliminary determination that Mississippi’s SIP and practices are adequate for enforcement of control measures and regulation of

minor sources and modifications related to the 2008 8-hour ozone NAAQS.

4. 110(a)(2)(D)(i)(I) and (II): Interstate Pollution Transport: Section 110(a)(2)(D)(i) has two components; 110(a)(2)(D)(i)(I) and 110(a)(2)(D)(II). Each of these components have two subparts resulting in four distinct components, commonly referred to as ‘‘prongs,’’ that must be addressed in

infrastructure SIP submissions. The first two prongs, which are codified in section 110(a)(2)(D)(i)(I), are provisions that prohibit any source or other type of emissions activity in one state from contributing significantly to nonattainment of the NAAQS in another state (‘‘prong 1’’), and interfering with maintenance of the NAAQS in another state (‘‘prong 2’’). The third and fourth prongs, which are codified in section 110(a)(2)(D)(i)(II), are provisions that prohibit emissions activity in one state interfering with measures required to prevent significant deterioration of air quality in another state (‘‘prong 3’’), or to protect visibility in another state (‘‘prong 4’’). With respect to Mississippi’s infrastructure SIP

submissions related to the interstate transport requirements of section 110(a)(2)(D)(i)(I) and 110(a)(2)(D)(i)(II) (prongs 1 through 4), EPA is not proposing any action today regarding these requirements and instead will act on these portions of the submissions in a separate action.

5. 110(a)(2)(D)(ii): Interstate Pollution

Abatement and International Air

Pollution: Section APC–S–2—Permit Regulations For The Construction and/ or Operation of Air Emissions Equipment, provides how MDEQ will notify neighboring states of potential impacts from new or modified sources consistent with the requirements of 40 CFR 51.166. Mississippi does not have any pending obligation under section

115 and 126 of the CAA. EPA has made the preliminary determination that Mississippi’s SIP and practices are adequate for insuring compliance with the applicable requirements relating to interstate and international pollution

abatement for the 2008 8-hour ozone NAAQS.


### 69793 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

21 Mississippi’s October 11, 2012, infrastructure SIP submission only addressed compliance with 110(a)(2)(E)(ii) respecting CAA section 128 requirements. On May 8, 2014, Mississippi clarified to EPA that the provisions submitted in the October 11, 2012, SIP submission to comply with 110(a)(2)(E)(ii) for the PM 2.5 NAAQS infrastructure

SIP were also intended to cover the 2008 Lead and 2008 8-hour ozone NAAQS infrastructure SIP.

22 EPA took similar action with respect to Mississippi’s section 110(a)(2)(E)(ii) submission for

the 1997 and 2006 PM 2.5 NAAQS. 6. 110(a)(2)(E): Adequate Resources and Authority, Conflict of Interest, and Oversight of Local Governments and Regional Agencies: Section 110(a)(2)(E) requires that each implementation plan provide (i) necessary assurances that the State will have adequate personnel, funding, and authority under state law to carry out its implementation plan, (ii) that the State comply with the requirements respecting State Boards pursuant to section 128 of the Act, and (iii) necessary assurances that, where

the State has relied on a local or regional government, agency, or instrumentality for the implementation of any plan provision, the State has responsibility for ensuring adequate implementation of such plan provisions. EPA is proposing to approve Mississippi’s SIP as meeting the requirements of sections 110(a)(2)(E)(i) and (iii). EPA is proposing to approve in part and disapprove in part Mississippi’s SIP respecting section 110(a)(2)(E)(ii). EPA’s rationale for today’s proposals respecting each section of 110(a)(2)(E) is described in

turn below.

To satisfy the requirements of sections 110(a)(2)(E)(i) and (iii), Mississippi provides that MDEQ is responsible for promulgating rules and regulations for the NAAQS, emissions standards general policies, a system of permits, fee schedules for the review of plans, and other planning needs as found in Mississippi Code Title 49, Section 49– 17–17(d) and Section 49–17–17(h) (Appendix A–9). As evidence of the adequacy of MDEQ’s resources with respect to sub-elements (i) and (iii), EPA submitted a letter to Mississippi on March 28, 2014, outlining 105 grant

commitments and the current status of these commitments for fiscal year 2013. The letter EPA submitted to Mississippi

can be accessed at www.regulations.gov using Docket ID No. EPA–R04–OAR– 2012–0698. Annually, states update these grant commitments based on current SIP requirements, air quality planning, and applicable requirements related to the NAAQS. Mississippi satisfactorily met all commitments agreed to in the Air Planning Agreement for fiscal year 2013, therefore Mississippi’s grants were finalized and

closed out. EPA has made the preliminary determination that Mississippi has adequate resources for implementation of the 2008 8-hour ozone NAAQS.

To meet the requirements of section 110(a)(2)(E)(ii), states must comply with the requirements respecting state boards pursuant to section 128 of the Act. Section 128 of the CAA requires that states include provisions in their SIP to address conflicts of interest for state

boards or bodies that oversee CAA permits and enforcement orders and

disclosure of conflict of interest requirements. Specifically, CAA section 128(a)(1) necessitates that each SIP shall require that at least a majority of any board or body which approves permits or enforcement orders shall be subject to the described public interest service and

income restrictions therein. Subsection 128(a)(2) requires that the members of any board or body, or the head of an executive agency with similar power to approve permits or enforcement orders under the CAA, shall also be subject to

conflict of interest disclosure requirements.

To meet its section 110(a)(2)(E)(ii) obligations for the 2008 Ozone NAAQS, Mississippi’s infrastructure SIP

submissions cite the State’s revision to its SIP to meet the requirements of CAA

section 128 for the 1997 and 2006 PM 2.5 NAAQS, which was submitted to EPA on October 11, 2012. 21 Based upon the review of the laws and provisions as contained in MDEQ’s October 11, 2012, SIP revision, which have since been incorporated into the SIP, EPA is proposing to approve the section 110(a)(2)(E)(ii) portions of the

infrastructure SIP submission as it relates to the public interest requirements of section 128(a)(1) and

the conflict of interest disclosure provisions of section 128(a)(2). EPA is also proposing to disapprove the section 110(a)(2)(E)(ii) portion of the

infrastructure SIP submission as it pertains to compliance with the significant portion of income requirement of section 128(a)(1) for the 2008 8-hour ozone NAAQS. 22

With respect to the public interest requirement of section 128(a)(1) and the adequate disclosure of conflicts of interest requirement of section 128(a)(2), EPA has previously found these requirements to be satisfied by the existing provisions in Mississippi’s SIP.

See 78 FR 20793.

With respect to the significant portion of income requirement of section 128(a)(1), the provisions included in the October 11, 2012 infrastructure SIP submission did not preclude at least a majority of the members of the Mississippi Board from receiving a significant portion of their income from persons subject to permits or enforcement orders issued by the Mississippi Boards. While the submitted laws and provisions preclude members of the Mississippi Boards from certain types of income ( e.g., contracts with State or political subdivisions thereof, or income obtained through the use of his or her public office or obtained to influence a decision of the Mississippi Boards), they do not preclude a majority of members of the Mississippi Boards from deriving any significant portion of their income from persons subject to permits or enforcement orders so long as

that income is not derived from one of the proscribed methods described in the laws and provisions submitted by the State. Because a majority of board members may still derive a significant portion of income from persons subject to permits or enforcement orders issued by the Mississippi Boards, the Mississippi SIP does not meet the section 128(a)(1) majority requirements respecting significant portion of income, and as such, EPA is today proposing to disapprove the State’s 110(a)(2)(E)(ii) submission as it relates only to this portion of section 128(a)(1).

Accordingly, EPA is proposing to approve the section 110(a)(2)(E)(ii) submission as it relates to the public interest requirements of section 128(a)(1) and the conflict of interest disclosure provisions of section 128(a)(2) and proposing to disapprove Mississippi’s section 110(a)(2)(E)(ii) submission as it pertains to compliance with the significant portion of income requirement of section 128(a)(1) for the 2008 8-hour ozone NAAQS.

7. 110(a)(2)(F): Stationary source monitoring system: Section APC–S–2— Permit Regulations for the Construction and/or Operation of Air Emissions Equipment, establishes requirements for emissions compliance testing utilizing emissions sampling and analysis. It

further describes how the State ensures the quality of its data through observing emissions and monitoring operations. MDEQ uses these data to track progress towards maintaining the NAAQS, develop control and maintenance strategies, identify sources and general emission levels, and determine compliance with emission regulations and additional EPA requirements. Mississippi Code 49, Section 49–17–21 (Appendix A–9) provides MDEQ with the authority to require the maintenance of records related to the operation of air contaminant sources and any authorized representative of the Commission may examine and copy any such records or memoranda pertaining to the operation


### 69794 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

of such contaminant source. Section APC–S–2 lists requirements for compliance testing and reporting that is required to be included in any MDEQ air pollution permit and requires that copies of records relating to the operation of air contamination sources

be submitted to the Permit Board as required by the permit or upon request. State-approved regulation Section APC–

S–1—Air Emission Regulations For The Prevention, Abatement, and Control of
Air Contaminants, authorizes source owners or operators to use any credible

evidence or information relevant to

whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test had been performed, for the purpose of submitting compliance certifications. Accordingly, EPA is unaware of any provision preventing the use of credible evidence in the Mississippi SIP.

Additionally, Mississippi is required

to submit emissions data to EPA for purposes of the National Emissions Inventory (NEI). The NEI is EPA’s central repository for air emissions data. EPA published the Air Emissions Reporting Rule (AERR) on December 5, 2008, which modified the requirements for collecting and reporting air emissions data (73 FR 76539). The

AERR shortened the time states had to report emissions data from 17 to 12 months, giving states one calendar year

to submit emissions data. All states are required to submit a comprehensive emissions inventory every three years and report emissions for certain larger sources annually through EPA’s online Emissions Inventory System (EIS). States report emissions data for the six criteria pollutants and the precursors that form them—nitrogen oxides, sulfur dioxide, ammonia, lead, carbon monoxide, particulate matter, and VOCs. Many states also voluntarily report emissions of hazardous air pollutants. Mississippi made its latest update to the 2012 NEI on January 9, 2014. EPA compiles the emissions data, supplementing it where necessary, and releases it to the general public through

the Web site http://www.epa.gov/ttn/ chief/eiinformation.html. EPA has made the preliminary determination that Mississippi’s SIP and practices are adequate for the stationary source monitoring systems related to the 2008 8-hour ozone NAAQS.

8. 110(a)(2)(G): Emergency powers: This section of the CAA requires that states demonstrate authority comparable

with section 303 of the CAA and adequate contingency plans to implement such authority. Mississippi

Code Title 49 (Appendix A–9) and Section APC–S–3—Mississippi Regulations for the Prevention of Air Pollution Emergency Episodes, identify air pollution emergency episodes and preplanned abatement strategies. Specifically, Mississippi Code Title 49, Section 49–17–27 (Appendix A–9), states that in the event an emergency is found to exist by the Mississippi Commission on Environmental Quality, it may issue an emergency order as circumstances may require. Section APC–S–3 authorizes the MDEQ Director, once it has been determined that an Air Pollution Emergency Episode condition exists at one or more monitoring sites solely because of

emissions from a limited number of sources, to order source(s) to put into effect the emission control programs which are applicable for each episode stage. Section APC–S–3 also lists regulations to prevent the excessive buildup of air pollutants during air pollution episodes. EPA has made the preliminary determination that Mississippi’s SIP and practices are adequate for emergency powers related to the 2008 8-hour ozone NAAQS. Accordingly, EPA is proposing to approve Mississippi’s infrastructure SIP submissions with respect to section 110(a)(2)(G).

9. 110(a)(2)(H): SIP revisions: MDEQ is responsible for adopting air quality rules and revising SIPs as needed to attain or maintain the NAAQS in Mississippi. Mississippi Code Title 49, Section 49–17–17(h) (Appendix A–9), provides MDEQ with the statutory authority to adopt, modify or repeal and promulgate ambient air and water quality standards and emissions standards for the State. As such, the State has the authority to revise the SIP to accommodate changes to NAAQS and

revise the SIP if the EPA Administrator finds the plan to be substantially inadequate to attain the NAAQS. EPA has made the preliminary determination that Mississippi’s SIP and practices adequately demonstrate a commitment to provide future SIP revisions related to the 2008 8-hour ozone NAAQS when

necessary.

10. 110(a)(2)(J): Consultation with Government Officials, Public Notification, and PSD and Visibility

Protection: EPA is proposing to approve Mississippi’s infrastructure SIP

submissions for the 2008 8-hour ozone NAAQS with respect to the general requirement in section 110(a)(2)(J) to include a program in the SIP that provides for meeting the applicable consultation requirements of section 121, and the public notification requirements of section 127. With respect to Mississippi’s infrastructure SIP submissions related to the preconstruction PSD permitting and visibility protection requirements, EPA is not proposing any action today regarding these requirements and instead will act on these portions of the submissions in a separate action. EPA’s rationale for applicable consultation requirements of section 121 and the public notification requirements of

section 127 is described below.

Consultation with government officials (121 consultation): This requirement is met through Section

APC–S–5—Mississippi Regulations for the Prevention of Significant Deterioration of Air Quality and Mississippi Code Title 49, Section 49– 17–17(c) (Appendix A–9), along with the State’s various implementations plans, such as the State’s Regional Haze Implementation Plan, provide for consultation between appropriate state, local, and tribal air pollution control agencies as well as the corresponding Federal Land Managers whose jurisdictions might be affected by SIP development activities. Mississippi adopted state-wide consultation procedures for the implementation of transportation conformity. These consultation procedures were developed in coordination with the transportation partners in the State and are consistent with the approaches used for development of mobile inventories for SIPs. Implementation of transportation conformity as outlined in the consultation procedures requires MDEQ to consult with federal, state and local transportation and air quality agency officials on the development of motor vehicle emissions budgets. EPA has made the preliminary determination that Mississippi’s SIP and practices adequately demonstrate that the State meets applicable requirements related to consultation with government officials for the 2008 8-hour ozone NAAQS when necessary. Accordingly, EPA is proposing to approve Mississippi’s

infrastructure SIP submissions with respect to section 110(a)(2)(J) consultation with government officials.

Public notification: These requirements are met through regulation

APC–S–3—Mississippi Regulations for the Prevention of Air Pollution Emergency Episodes, which requires that MDEQ notify the public of any air pollution alert, warning, or emergency. The MDEQ Web site also provides air quality summary data, air quality index reports and links to more information regarding public awareness of measures that can prevent such exceedances and of ways in which the public can participate in regulatory and other efforts to improve air quality. EPA has


### 69795 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

23 Title V program regulations are federallyapproved but not incorporated into the federallyapproved SIP. made the preliminary determination that Mississippi’s SIP and practices adequately demonstrate the State’s ability to provide public notification

related to the 2008 8-hour ozone NAAQS when necessary. Accordingly, EPA is proposing to approve Mississippi’s infrastructure SIP submissions with respect to section 110(a)(2)(J) public notification.

11. 110(a)(2)(K): Air Quality Modeling and Submission of Modeling Data:
Sections APC–S–2, V. B.—Permit Regulation for the Construction and/or Operation of Air Emissions Equipment,

and APC–S–5—Mississippi Regulations for the Prevention of Significant Deterioration of Air Quality, specify that required air modeling be conducted in accordance with 40 CFR part 51, Appendix W ‘‘Guideline on Air Quality Models,’’ as incorporated into the Mississippi SIP. These standards demonstrate that Mississippi has the authority to perform air quality monitoring and provide relevant data for the purpose of predicting the effect on ambient air quality of the 2008 8- hour ozone NAAQS. Additionally, Mississippi supports a regional effort to coordinate the development of

emissions inventories and conduct regional modeling for several NAAQS, including the 2008 8-hour ozone NAAQS, for the southeastern states. Taken as a whole, Mississippi’s air quality regulations and practices demonstrate that MDEQ has the authority to provide relevant data for the purpose of predicting the effect on ambient air quality of the 2008 8-hour ozone NAAQS. EPA has made the preliminary determination that Mississippi’s SIP and practices adequately demonstrate the State’s ability to provide for air quality and modeling, along with analysis of the associated data, related to the 2008 8- hour ozone NAAQS when necessary. Accordingly, EPA is proposing to approve Mississippi’s infrastructure SIP submissions with respect to section 110(a)(2)(K).

12. 110(a)(2)(L): Permitting fees: This element necessitates that the SIP require the owner or operator of each major stationary source to pay to the permitting authority, as a condition of any permit required under the CAA, a fee sufficient to cover (i) the reasonable costs of reviewing and acting upon any application for such a permit, and (ii) if the owner or operator receives a permit for such source, the reasonable costs of implementing and enforcing the terms and conditions of any such permit (not including any court costs or other costs associated with any enforcement action), until such fee requirement is superseded with respect to such sources by the Administrator’s approval of a fee program under title V.

Mississippi’s Mississippi Code Title 49, Section 49–2–9(c) (Appendix A–9), authorizes MDEQ to apply for, receive, and expend Federal or state funds in order to operate its air programs. Mississippi SIP Mississippi Code Title 49, Section 49–17–30 (Appendix A–9), provides for the assessment of title V permit fees to cover the reasonable cost of reviewing and acting upon air permitting activities in the state including title V, PSD and NNSR permits. Mississippi Code Title 49, Section 49–17–14 (Appendix A–9), allows MDEQ to expend or utilize monies in the Mississippi Air Operating Permit Program Fee Trust Fund to pay

all reasonable direct and indirect costs associated with the development and administration of the title V program and the PSD and NNSR permitting programs. The Mississippi Air Operating Permit Program Fee Trust Fund consists of state legislative appropriations, Federal grant funds and title V fees. Additionally, Mississippi has a federally-approved title V operating permit program at Section

APC–S–6 23 that covers the implementation and enforcement of PSD and NNSR permits after they have

been issued. EPA has made the preliminary determination that Mississippi adequately provide for permitting fees related to the 2008 8- hour NAAQS when necessary.

13. 110(a)(2)(M): Consultation and Participation by Affected Local Entities: Mississippi Code Title 49, Sections 49– 17–17(c) 49–17–19(b) (Appendix A–9) requires that MDEQ notify the public of an application, preliminary determination, the activity or activities involved in the permit action, any emissions change associated with any permit modification, and the opportunity for comment prior to making a final permitting decision. Additionally, MDEQ works closely with local political subdivisions during the development of its Transportation Conformity SIP and Regional Haze SIP. EPA has made the preliminary determination that Mississippi’s SIP and practices adequately demonstrate

consultation with affected local entities

related to the 2008 8-hour ozone NAAQS when necessary.

V. Proposed Action

With the exception of the PSD permitting requirements for major sources of section 110(a)(2)(C) and (J), the interstate transport requirements of section 110(a)(2)(D)(i)(I) and (II) (prongs 1 through 4), the state board majority requirements respecting the significant portion of income of section 110(a)(2)(E)(ii), and the visibility requirements of section 110(a)(2)(J), EPA is proposing to approve that MDEQ’s infrastructure SIP submissions, submitted May 29, 2012, and July 26, 2012, for the 2008 8-hour ozone NAAQS

have met the above described infrastructure SIP requirements. EPA is proposing to disapprove in part section 110(a)(2)(E)(ii) of Mississippi’s

infrastructure submissions because a majority of board members may still derive a significant portion of income from persons subject to permits or enforcement orders issued by the Mississippi Boards, therefore, its current SIP does not meet the section 128(a)(1) majority requirements respecting significant portion of income. This proposed approval in part and disapproval in part, however, does not include the PSD permitting requirements for major sources of section 110(a)(2)(C) and (J), the interstate transport requirements of section 110(a)(2)(D)(i)(I) and (II) (prongs 1 through 4), and the visibility requirements of section 110(a)(2)(J) and will be addressed by EPA in a separate

action.

Under section 179(a) of the CAA, final disapproval of a submittal that addresses a requirement of a CAA Part D Plan or is required in response to a finding of substantial inadequacy as described in CAA section 110(k)(5) (SIP call) starts a sanctions clock. The portion of section 110(a)(2)(E)(ii) provisions (the provisions being proposed for disapproval in today’s notice) were not submitted to meet requirements for Part D or a SIP call, and therefore, if EPA takes final action to disapprove this submittal, no sanctions will be triggered. However, if this disapproval action is finalized, that final action will trigger the requirement under section 110(c) that EPA promulgate a federal implementation plan (FIP) no later than 2 years from the date of the disapproval unless the State corrects the deficiency, and EPA approves the plan or plan revision before EPA promulgates such FIP.

VI. Statutory and Executive Order

Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations.

See 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions,


### 69796 Federal Register / Vol. 79, No. 226 / Monday, November 24, 2014 / Proposed Rules

EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this proposed action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

• is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44

U.S.C. 3501 et seq. );

• is certified as not having a significant economic impact on a

substantial number of small entities under the Regulatory Flexibility Act (5

U.S.C. 601 et seq. );

• does not contain any unfunded mandate or significantly or uniquely affect small governments, as described

in the Unfunded Mandates Reform Act of 1995 (Public Law 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, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an

Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose

substantial direct costs on tribal governments or preempt tribal law.

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

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Arizona to address the requirements of section 110(a)(1) and (2) of the Clean Air Act (CAA) for the 2008 Lead (Pb) and 2008 ozone national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each State adopt

and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA. We refer to such

SIP revisions as ‘‘infrastructure’’ SIPs because they are intended to address basic structural SIP requirements for new or revised NAAQS including, but not limited to, legal authority, regulatory structure, resources, permit programs, monitoring, and modeling necessary to assure attainment and

maintenance of the standards. In addition, we are proposing to approve several state provisions addressing CAA conflict of interest and monitoring requirements into the Arizona SIP. We are taking comments on this proposal and plan to follow with a final action.
