Air Plan Approval/Disapproval; Alabama Infrastructure Requirements for the 2010 Nitrogen Dioxide National Ambient Air Quality Standards

AGENCY:

Environmental Protection Agency.

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve in part and disapprove in part portions of the April 23, 2013, and December 9, 2015, update State Implementation Plan (SIP) submissions, submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), for inclusion into the Alabama SIP. This proposal pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2010 1-hour nitrogen dioxide (NO₂) national ambient air quality standard (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. ADEM certified that the Alabama SIP contains provisions that ensure the 2010 1-hour NO₂ NAAQS is implemented, enforced, and maintained in Alabama. With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, and visibility in other states, for which EPA is proposing no action through this notice, and with the exception of the provisions respecting state boards, for which EPA is proposing disapproval, EPA is proposing to approve Alabama's infrastructure SIP submissions provided to EPA on April 23, 2013, and updated on December 9, 2015, as satisfying the required infrastructure elements for the 2010 NO₂ NAAQS.

SUPPLEMENTARY INFORMATION:

I. Background

On February 9, 2010, EPA published a new 1-hour primary NAAQS for NO₂ at a level of 100 parts per billion (ppb), based on a 3-year average of the 98th percentile of the yearly distribution of 1-hour daily maximum concentrations. See 75 FR 6474. Pursuant to section 110(a)(1) of the CAA, states are required to submit SIPs meeting the requirements of section 110(a)(2) within three years after promulgation of a new or revised NAAQS. Sections 110(a)(2) require states to address basic SIP requirements, including emissions inventories, monitoring, and modeling to assure attainment and maintenance of the NAAQS. States were required to submit such SIPs for the 2010 NO₂ NAAQS to EPA no later than January 22, 2013.

This action is proposing to approve Alabama's infrastructure SIP submissions for the applicable requirements of the 2010 1-hour NO₂ NAAQS, with the exception of the preconstruction PSD permitting requirements for major sources of section 110(a)(2)(C), prong 3 of (D)(i), and (J), the interstate transport provisions of section 110(a)(2)(D)(i), (prongs 1, 2 and 4), and the state board requirements of section 110(a)(2)(E)(ii). On March 18, 2015, EPA approved Alabama's April 23, 2013, infrastructure SIP submission regarding the PSD permitting requirements for major sources of sections 110(a)(2)(C), prong 3 of D(i) and (J) for the 2010 1-hour NO₂ NAAQS. See 80 FR 14019. Therefore, EPA is not proposing any action today pertaining to sections 110(a)(2)(C), prong 3 of D(i) and (J). Additionally, today, EPA is not taking action related to the interstate transport provisions pertaining to the contribution to nonattainment or interference with maintenance in other states of prongs 1 and 2 of section 110(a)(2)(D)(i), and prong 4 of (D)(i). With respect to Alabama's infrastructure SIP submissions related to section 110(a)(2)(E)(ii) requirements respecting the section 128 state board requirements, EPA is proposing to disapprove this element of Alabama's submissions in this rulemaking. For the aspects of Alabama's submittals proposed for approval today, EPA notes that the Agency is not approving any specific rule, but rather proposing that Alabama'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 2010 NO₂ NAAQS, states typically have met the basic program elements required in section 110(a)(2) through earlier SIP submissions in connection with previous NAAQS.

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

• 110(a)(2)(A): Emission Limits and Other Control Measures
• 110(a)(2)(B): Ambient Air Quality Monitoring/Data System
• 110(a)(2)(C): Programs for Enforcement of Control Measures and for Construction or Modification of Stationary Sources

• 110(a)(2)(D)(i)(I) and (II): Interstate Pollution Transport
• 110(a)(2)(D)(ii): Interstate Pollution Abatement and International Air Pollution
• 110(a)(2)(E): Adequate Resources and Authority, Conflict of Interest, and Oversight of Local Governments and Regional Agencies
• 110(a)(2)(F): Stationary Source Monitoring and Reporting
• 110(a)(2)(G): Emergency Powers
• 110(a)(2)(H): SIP revisions
• 110(a)(2)(I): Plan Revisions for Nonattainment Areas

• 110(a)(2)(J): Consultation with Government Officials, Public Notification, and PSD and Visibility Protection
• 110(a)(2)(K): Air Quality Modeling and Submission of Modeling Data
• 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 Alabama that addresses the infrastructure requirements of CAA sections 110(a)(1) and 110(a)(2) for the 2010 NO₂ 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. 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. 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. 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. 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.

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 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.

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. EPA most recently issued guidance for infrastructure SIPs on September 13, 2013 (2013 Guidance). EPA developed this document to provide states with up-to-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. 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, including GHGs. 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 implementation plan meets basic structural requirements. For example, section 110(a)(2)(C) includes, inter alia, the requirement that states have a program to regulate minor new sources. Thus, EPA evaluates whether the state has an EPA-approved 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 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. 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 implementation plan is substantially inadequate to attain or maintain the NAAQS, to mitigate interstate transport, or to otherwise comply with the CAA. Section 110(k)(6) authorizes EPA to correct errors in past actions, such as past approvals of SIP submissions. 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.

IV. What is EPA's analysis of how Alabama addressed the elements of the sections 110(a)(1) and (2) “infrastructure” provisions?

Alabama's infrastructure 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: Section 110(a)(2)(A) requires that each implementation plan include enforceable emission limitations and other control measures, means, or techniques (including economic incentives such as fees, marketable permits, and auctions of emissions rights), as well as schedules and timetables for compliance, as may be necessary or appropriate to meet the applicable requirements. Several regulations within Alabama's SIP are relevant to air quality control. The regulations described below have been federally approved in the Alabama SIP and include enforceable emission limitations and other control measures for activities that contribute to NO₂ concentrations in the ambient air and provide ADEM the authority to establish such limits and measures as well as schedules for compliance to meet the applicable requirements of the CAA. ADEM Admin. Code r. 335-3-1-.03—Ambient Air Quality Standards, authorizes ADEM to adopt rules for the control of air pollution in order to comply with NAAQS, including those necessary to obtain EPA approval under section 110 of the CAA. ADEM Admin. Code r. 335-3-1-.06—Compliance Schedule, sets the schedule for the State's Air Pollution Control rules and regulations to be consistent with the requirements of the CAA. ADEM Admin. Code r. 335-3-1-.05—Sampling and Testing Methods, details the authority and means with which ADEM can require testing and emissions verification. EPA has made the preliminary determination that the provisions contained in these regulations satisfy section 110(a)(2)(A) for the 2010 1-hour NO₂ 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 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 is addressing such state regulations in a separate action.

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. These requirements are met through ADEM Admin. Code r. 335-3-1-.03—Ambient Air Quality Standards, ADEM Admin. Code r. 335-3-1-.05—Sampling and Testing Methods, and ADEM Admin. Code r. 335-3-1-.04—Monitoring, Records, and Reporting. These SIP-approved rules along with Alabama's Ambient Air Monitoring Network Plan, 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. 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 state's ambient monitors and auxiliary support equipment. The latest monitoring network plan for Alabama was submitted to EPA on July 22, 2015, and on November 19, 2015, EPA approved this plan. Alabama's approved 2015 monitoring network plan can be accessed at www.regulations.gov using Docket ID No. EPA-R04-OAR-2014-0756. EPA has made the preliminary determination that Alabama's SIP and practices are adequate for the ambient air quality monitoring and data system related to the 2010 1-hour NO₂ NAAQS.

3. 110(a)(2)(C) Programs for Enforcement of Control Measures and for Construction or Modification of Stationary Sources: This element consists of three sub-elements; enforcement, state-wide regulation of new and modified minor sources and minor modifications of major sources; and preconstruction permitting of major sources and major modifications in areas designated attainment or unclassifiable for the subject NAAQS as required by CAA title I part C (i.e., the major source PSD program). ADEM's 2010 1-hour NO₂ NAAQS infrastructure SIP submissions cited SIP provisions to address these requirements. Specifically, the submissions cited ADEM Admin. Code r 335-3-14-.01—“General Provisions,” 335-3-14-.02,—“Permit Procedure”, 334-3-14-.03—“Standards for Granting Permits”, 335-3-14-.04—“Prevention of Significant Deterioration in Permitting” and 335-3-14-.05—“Air Permits Authorizing Construction in or Near Nonattainment Areas”. As discussed further below, in this action EPA is only proposing to approve the enforcement, and the regulation of minor sources and minor modifications aspects of Alabama's section 110(a)(2)(C) infrastructure SIP submissions.

Enforcement: ADEM's above-described, SIP-approved regulations provide for enforcement of NO₂ emission limits and control measures through enforceable permits for new or modified stationary sources. Note also that ADEM has authority to issue enforcement orders and assess penalties (see Code sections 22-22A-5, 22-28-10 and 22-28-22).

PSD Permitting for Major Sources: With respect to Alabama's April 23, 2013, infrastructure SIP submission related to the PSD permitting requirements of major sources for section 110(a)(2)(C), EPA took final action to approve these provisions for the 2010 1-hour NO₂ NAAQS on March 18, 2015. See 80 FR 14019.

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 2010 1-hour NO₂ NAAQS. ADEM Admin. Code r 334-3-14-.03—“Standards for Granting Permits” governs the preconstruction permitting of minor modifications and construction of minor stationary sources. EPA has made the preliminary determination that Alabama's SIP and practices are adequate for program enforcement of control measures and regulation of minor sources and modifications related to the 2010 1-hour NO₂ NAAQS.

4. 110(a)(2)(D) Interstate Pollution Transport: Section 110(a)(2)(D)(i) has two components; 110(a)(2)(D)(i)(I) and 110(a)(2)(D)(i)(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 from 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”).

110(a)(2)(D)(i)(I)—prongs 1 through 2: EPA is not proposing any action in this rulemaking related to the interstate transport provisions pertaining to the contribution to nonattainment or interference with maintenance in other states of section 110(a)(2)(D)(i)(I) (prongs 1 and 2) because Alabama's 2010 1-hour NO₂ NAAQS infrastructure submissions did not address prongs 1 and 2.

110(a)(2)(D)(i)(II)—prong 3: With respect to Alabama's infrastructure SIP submission related to the interstate transport requirements for PSD of section 110(a)(2)(D)(i)(II) (prong 3), EPA took final action to approve Alabama's April 23, 2013, infrastructure SIP submission regarding prong 3 of D(i) for the 2010 1-hour NO₂ NAAQS on March 18, 2015. See 80 FR 14019.

110(a)(2)(D)(i)(II)—prong 4: EPA is not proposing any action in this rulemaking related to the interstate transport provisions pertaining to visibility protection in other states of section 110(a)(2)(D)(i)(II) (prong 4) and will consider these requirements in relation to Alabama's 2010 1-hour NO₂ NAAQS infrastructure submissions in a separate rulemaking.

5. 110(a)(2)(D)(ii) Interstate Pollution Abatement and International Air Pollution: Section 110(a)(2)(D)(ii) requires SIPs to include provisions insuring compliance with sections 115 and 126 of the Act, relating to interstate and international pollution abatement. ADEM Admin. Code r. 335-3-14-.04—Prevention of Significant Deterioration in Permitting describes how Alabama notifies neighboring states of potential emission impacts from new or modified sources applying for PSD permits. This regulation requires ADEM to provide an opportunity for a public hearing to the public, which includes State or local air pollution control agencies, “whose lands may be affected by emissions from the source or modification” in Alabama. Additionally, Alabama does not have any pending obligation under sections 115 and 126 of the CAA. EPA has made the preliminary determination that Alabama's SIP and practices are adequate for insuring compliance with the applicable requirements relating to interstate and international pollution abatement for the 2010 1-hour NO₂ 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 Alabama's SIP as meeting the requirements of sub-elements 110(a)(2)(E)(i) and (iii). With respect to 110(a)(2)(E)(ii) (regarding state boards), EPA is proposing disapproval of this sub-element. EPA's rationale respecting each sub-element is described in turn below.

In support of EPA's proposal to approve sub-elements 110(a)(2)(E)(i) and (iii), ADEM's infrastructure submissions demonstrate that it 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 authorized at Ala. Code section 22-28-11 and section 22-28-9. Ala. Code section 22-28-23 does not allow the local programs to be less strict than the Alabama SIP/regulations and allows for oversight from the State. As evidence of the adequacy of ADEM's resources with respect to sub-elements (i) and (iii), EPA submitted a letter to Alabama on April 19, 2016, outlining 105 grant commitments and current status of these commitments for fiscal year 2015. The letter EPA submitted to Alabama can be accessed at www.regulations.gov using Docket ID No. EPA-R04-OAR-2014-0431. Annually, states update these grant commitments based on current SIP requirements, air quality planning, and applicable requirements related to the NAAQS. There were no outstanding issues in relation to the SIP for fiscal year 2015, therefore, Alabama's grants were finalized and closed out. Alabama's funding is also met through the state's title V fee program at ADEM Admin. Code r. 335-1-7—Air Division Operating Permit Fees and ADEM Admin. Code r. 335-1-6—Application Fees. EPA has made the preliminary determination that Alabama has adequate resources for implementation of the 2010 1-hour NO₂ NAAQS.

Section 110(a)(2)(E)(ii) requires that the state comply with section 128 of the CAA. Section 128 requires that: (1) The majority of members of the state board or body which approves permits or enforcement orders represent the public interest and do not derive any significant portion of their income from persons subject to permitting or enforcement orders under the CAA; and (2) any potential conflicts of interest by such board or body, or the head of an executive agency with similar powers be adequately disclosed. After reviewing Alabama's SIP, EPA has made the preliminary determination that the State's implementation plan does not contain provisions to comply with section 128 of the Act, and thus Alabama's April 23, 2013, and December 9, 2015, infrastructure SIP submissions do not meet the requirements of the Act. While Alabama has state statutes that may address, in whole or part, requirements related to state boards at the state level, these provisions are not included in the SIP as required by the CAA. Based on an evaluation of the federally-approved Alabama SIP, EPA is proposing to disapprove Alabama's certification that its SIP meets the requirements of 110(a)(2)(E)(ii) of the CAA for the 2010 1-hour NO₂ NAAQS. The submitted provisions which purport to address 110(a)(2)(E)(ii) are severable from the other infrastructure elements. Therefore, EPA is proposing to disapprove those provisions which relate only to sub-element 110(a)(2)(E)(ii).

7. 110(a)(2)(F) Stationary Source Monitoring System and Reporting: Section 110(a)(2)(F) requires SIPs to meet applicable requirements addressing: (i) The installation, maintenance, and replacement of equipment, and the implementation of other necessary steps, by owners or operators of stationary sources to monitor emissions from such sources, (ii) periodic reports on the nature and amounts of emissions and emissions related data from such sources, and (iii) correlation of such reports by the state agency with any emission limitations or standards established pursuant to this section, which reports shall be available at reasonable times for public inspection. ADEM's infrastructure SIP submissions describe the establishment of requirements for compliance testing by emissions sampling and analysis, and for emissions and operation monitoring to ensure the quality of data in the State. The Alabama infrastructure submissions also describe how the major source and minor source emission inventory programs collect emission data throughout the State and ensure the quality of such data. Alabama meets these requirements through ADEM Admin. Code r. 335-3-1-.04—Monitoring, Records, and Reporting, and 335-3-12—Continuous Monitoring Requirements for Existing Sources. ADEM Admin. Code r. 335-3-1-.04, details how sources are required as appropriate to establish and maintain records; make reports; install, use, and maintain such monitoring equipment or methods and provide periodic emission reports as the regulation requires. These reports and records are required to be compiled, and submitted on forms furnished by the State. Additionally, ADEM Admin. Code r. 335-3-12-.02 requires owners and operators of emissions sources to “install, calibrate, operate and maintain all monitoring equipment necessary for continuously monitoring the pollutants.”

ADEM Admin. Code r. 335-3-1-.13—Credible Evidence, makes allowances for owners and/or operators to utilize “any credible evidence or information relevant” to demonstrate compliance with applicable requirements if the appropriate performance or compliance test had been performed, for the purpose of submitting compliance certification and can be used to establish whether or not an owner or operator has violated or is in violation of any rule or standard. Accordingly, EPA is unaware of any provision preventing the use of credible evidence in the Alabama SIP.

Additionally, Alabama 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. States report emissions data for the six criteria pollutants and the precursors that form them—nitrogen oxides, SO₂, ammonia, lead, carbon monoxide, particulate matter, and volatile organic compounds. Many states also voluntarily report emissions of hazardous air pollutants. Alabama made its latest update to the 2011 NEI on January 7, 2013. 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 Alabama's SIP and practices are adequate for the stationary source monitoring systems related to the 1-hour NO₂ NAAQS.

8. 110(a)(2)(G) Emergency Powers: This section requires that states demonstrate authority comparable with section 303 of the CAA and adequate contingency plans to implement such authority. ADEM Admin. Code r. 335-3-2—Air Pollution Emergency, provides for the identification of air pollution emergency episodes, episode criteria, and emissions reduction plans. Alabama's compliance with section 303 of the CAA and adequate contingency plans to implement such authority is also met at Ala. Code section 22-28-21 Air Pollution Emergencies. Ala. Code section 22-28-21 provides ADEM the authority to order “person or persons responsible for the operation or operations of one or more air contaminants sources” causing “imminent danger to human health or safety in question to reduce or discontinue emissions immediately.” The order establishes a hearing no later than 24-hours after issuance before the Environmental Management Commission which can affirm, modify or set aside the Director's order. Additionally, the Governor can, by proclamation, declare, as to all or any part of said area, that an air pollution emergency exists and exercise certain powers in whole or in part, by the issuance of an order or orders to protect the public health. Under Ala. Code sections 22-28-3(a) and 22-28-10(2), ADEM also has the authority to issue such orders as may be necessary to effectuate the purposes of the Alabama Pollution Control Act, which includes achieving and maintaining such levels of air quality as will protect human health and safety and, to the greatest degree practicable, prevent injury to plant and animal life and property, foster the comfort and convenience of the people, promote the social development of this state and facilitate the enjoyment of the natural attractions of the state. EPA has made the preliminary determination that Alabama's SIP and state laws are adequate for emergency powers related to the 2010 1-hour NO₂ NAAQS. Accordingly, EPA is proposing to approve Alabama's infrastructure SIP submissions with respect to section 110(a)(2)(G).

9. 110(a)(2)(H) SIP Revisions: Section 110(a)(2)(H), in summary, requires each SIP to provide for revisions of such plan: (i) As may be necessary to take account of revisions of such national primary or secondary ambient air quality standard or the availability of improved or more expeditious methods of attaining such standard, and (ii) whenever the Administrator finds that the plan is substantially inadequate to attain the NAAQS or to otherwise comply with any additional applicable requirements. ADEM is responsible for adopting air quality rules and revising SIPs as needed to attain or maintain the NAAQS. Alabama has the ability and authority to respond to calls for SIP revisions, and has provided a number of SIP revisions over the years for implementation of the NAAQS. ADEM Admin. Code r. 335-1-1-.03—Organization and Duties of the Commission, provides ADEM with the authority to establish, adopt, promulgate, modify, repeal and suspend rules, regulations, or environmental standards which may be applicable to Alabama or “any of its geographic parts.” Admin. Code r. 335-3-1-.03—Ambient Air Quality Standards, provides ADEM the authority to amend, revise, and incorporate the NAAQS into its SIP. EPA has made the preliminary determination that Alabama adequately demonstrates a commitment to provide future SIP revisions related to the 2010 1-hour NO₂ NAAQS when necessary. Accordingly, EPA is proposing to approve Alabama's infrastructure SIP submissions with respect to section 110(a)(2)(H).

10. 110(a)(2)(J) Consultation with Government Officials, Public Notification, and PSD and visibility Protection: EPA is proposing to approve Alabama's infrastructure SIP for the 2010 1-hour NO₂ NAAQS with respect to the general requirement in section 110(a)(2)(J) to include a program in the SIP that provides for meeting the applicable consultation requirements of section 121, the public notification requirements of section 127; and visibility protection requirements of part C of the Act. With respect to Alabama's infrastructure SIP submission related to the preconstruction PSD permitting requirements of section 110(a)(2)(J), EPA took final action to approve Alabama's April 23, 2013, 2010 1-hour NO₂ NAAQS infrastructure SIP for these requirements on March 18, 2015. See 80 FR 14019. EPA's rationale for its proposed action regarding applicable consultation requirements of section 121, the public notification requirements of section 127, and visibility protection requirements is described below.

Consultation with government officials (121 consultation): Section 110(a)(2)(J) of the CAA requires states to provide a process for consultation with local governments, designated organizations and federal land managers (FLMs) carrying out NAAQS implementation requirements pursuant to section 121 relative to consultation. ADEM Admin. Code r. 335-3-1-.03—Ambient Air Quality Standards, as well as its Regional Haze Implementation Plan (which allows for continued consultation with appropriate state, local, and tribal air pollution control agencies as well as the corresponding FLMs), provide for consultation with government officials whose jurisdictions might be affected by SIP development activities. Specifically, Alabama adopted state-wide consultation procedures for the implementation of transportation conformity, which are used for development of mobile inventories for SIPs. Required partners covered by Alabama's consultation procedures include federal, state and local transportation and air quality agency officials. EPA has made the preliminary determination that Alabama's SIP and practices adequately demonstrate consultation with government officials related to the 2010 1-hour NO₂ NAAQS when necessary. Accordingly, EPA is proposing to approve Alabama's infrastructure SIP submissions with respect to section 110(a)(2)(J) consultation with government officials.

Public notification (127 public notification): ADEM Admin. Code r. 335-3-14-.01(7)—Public Participation, ADEM Admin. Code r. 335-3-14-.05(13)—Public Participation, and Ala. Code section 22-28-21—Air Pollution Emergencies provides for public notification and resolution when air pollution episodes occur. Furthermore, ADEM has several public notice mechanisms in place to provide daily air quality forecasts for ozone and fine particulate matter to the public, including: EPA AirNow, ADEM Web site postings and customized emails through Enviroflash for registered individuals. When air quality is expected to be poor, an air quality alert is issued for a city, the local National Weather Service (NWS) office is alerted and the forecast is posted on the NWS Web site. Additionally, for some cities in Alabama (e.g., Birmingham), the county planning organizations are alerted and the forecast is distributed to the media, and other interested groups. EPA has made the preliminary determination that Alabama's SIP and practices adequately demonstrate the State's ability to provide public notification related to the 2010 1-hour NO₂ NAAQS when necessary.

Visibility protection: EPA's 2013 Guidance notes that it does not treat the visibility protection aspects of section 110(a)(2)(J) as applicable for purposes of the infrastructure SIP approval process. ADEM referenced its regional haze program as germane to the visibility component of section 110(a)(2)(J). EPA recognizes that states are subject to visibility protection and regional haze program requirements under Part C of the Act (which includes sections 169A and 169B). However, there are no newly applicable visibility protection obligations after the promulgation of a new or revised NAAQS. Thus, EPA has determined that states do not need to address the visibility component of 110(a)(2)(J) in infrastructure SIP submittals so ADEM does not need to rely on its regional haze program to fulfill its obligations under section 110(a)(2)(J). As such, EPA has made the preliminary determination that Alabama's infrastructure SIP submissions are approvable for the visibility protection element of section 110(a)(2)(J) in related to the 2010 1-hour NO₂ NAAQS and that Alabama does not need to rely on its regional haze program to address this element.

11. 110(a)(2)(K) Air Quality and Modeling and Submission of Modeling Data: Section 110(a)(2)(K) of the CAA requires that SIPs provide for performing air quality modeling so that effects on air quality of emissions from NAAQS pollutants can be predicted and submission of such data to the EPA can be made. ADEM Admin. Code r 335-3-1-.04—Monitoring, Records, and Reporting and 335-3-14-.04—Prevention of Significant Deterioration Permitting, specifically sub-paragraph (11)—Air Quality Models specify that required air modeling be conducted in accordance with 40 CFR part 51, Appendix W “Guideline on Air Quality Models”. ADEM Admin. Code r 335-3-1-.04—Monitoring, Records, and Reporting details how sources are required as appropriate to establish and maintain records; make reports; install, use, and maintain such monitoring equipment or methods and provide periodic emission reports as the regulation requires. These reports and records are required to be compiled, and submitted on forms furnished by the State. These provisions demonstrate that Alabama has the authority to provide relevant data for the purpose of predicting the effect of pollutants on ambient air quality of the 2010 1-hour NO₂ NAAQS. Additionally, Alabama participates in a regional effort to coordinate the development of emissions inventories and conduct regional modeling for several NAAQS, including the 2010 1-hour NO₂ NAAQS, for the southeastern states. Taken as a whole, Alabama's air quality regulations and practices demonstrate that ADEM has the authority to provide relevant data for the purpose of predicting the effect on ambient air quality of any emissions of any pollutant for which a NAAQS had been promulgated, and to provide such information to the EPA Administrator upon request. EPA has made the preliminary determination that Alabama'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 2010 1-hour NO₂ NAAQS. Accordingly, EPA is proposing to approve Alabama'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.

ADEM Admin. Code r. 335-1-6—Application Fees requires ADEM to charge permit-specific fees to the applicant/source as authorized by State legislation and Ala. Code section 22-22A-5. ADEM assures its permitting fee structure is sufficient for the reasonable cost of reviewing and acting upon PSD and nonattainment new source review (NNSR) permits. Additionally, Alabama has a fully approved title V operating permit program at ADEM Admin. Code r. 335-1-7—Air Division Operating Permit Fees, that covers the cost of implementation and enforcement of PSD and NNSR permits after they have been issued. EPA has made the preliminary determination that Alabama's SIP and practices adequately provide for permitting fees related to the 2010 1-hour NO₂ NAAQS, when necessary. Accordingly, EPA is proposing to approve Alabama's infrastructure SIP submissions with respect to section 110(a)(2)(L).

13. 110(a)(2)(M) Consultation and Participation by Affected Local Entities: This element requires states to provide for consultation and participation in SIP development by local political subdivisions affected by the SIP. ADEM Administrative Code 335-3-17-.01—Transportation Conformity and the interagency consultation process as directed by Alabama's approved Conformity SIP and 40 CFR 93.112 provide for consultation with local groups. More specifically, Alabama adopted consultation procedures for the implementation of transportation conformity which includes the development of mobile inventories for SIP development and the requirements that link transportation planning and air quality planning in nonattainment and maintenance areas. These consultation and participation procedures have been approved in the Alabama SIP as the non-regulatory provisions: “Alabama Interagency Transportation Conformity Memorandum of Agreement” and “Conformity SIP for Birmingham and Jackson County.” These provisions were approved on May 11, 2000, and March 26, 2009, respectively. See 65 FR 30362 and 74 FR 13118. Required partners covered by Alabama's consultation procedures include federal, state and local transportation and air quality agency officials. The state and local transportation agency officials are most directly impacted by transportation conformity requirements and are required to provide public involvement for their activities including the analysis demonstrating how they meet transportation conformity requirements. Additionally, Alabama has consulted with FLMs as a requirement of its regional haze SIP. EPA has made the preliminary determination that Alabama's SIP and practices adequately demonstrate consultation with affected local entities related to the 2010 1-hour NO₂ NAAQS when necessary.

V. Proposed Action

With the exception of interstate transport provisions pertaining to visibility protection requirements of section 110(a)(2)(D)(i)(II) (prong 4), and the state board requirements of section 110(a)(2)(E)(ii), EPA is proposing to approve that certain elements in Alabama's April 23, 2013, and December 9, 2015, SIP submissions for the 2010 1-hour NO₂ NAAQS have met the above-described infrastructure SIP requirements. EPA is proposing to disapprove section 110(a)(2)(E)(ii) of Alabama's infrastructure submissions because the State's implementation plan does not contain provisions to comply with section 128 of the Act, and thus Alabama's April 23, 2013, and December 9, 2015, infrastructure SIP submissions do not meet the requirements of the Act. The interstate transport requirements of section 110(a)(2)(D)(i)(II) (prong 4) will be addressed by EPA in a future action.

Under section 179(a) of the CAA, final disapproval of a submittal (or portion thereof) 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 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, 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
• Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
• Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

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.
