**Partial Approval and Disapproval of Air Quality State Implementation Plans;**  **Nevada; Infrastructure Requirements for Ozone, Nitrogen Dioxide, and** 
**Sulfur Dioxide**

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

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to partially approve and partially disapprove the Nevada State Implementation Plan (SIP) as meeting the requirements of the Clean Air Act (CAA or the Act) for the implementation, maintenance, and enforcement of the 2008 ozone, 2010 nitrogen dioxide (NO 2), and 2010 sulfur dioxide (SO 2 ) national ambient air quality standards (NAAQS). CAA section 110(a)(1) requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by the EPA, and that EPA
act on such SIPs. We refer to such SIPs 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 to our proposed partial approval and partial disapproval of Nevada’s infrastructure SIP, we are proposing to reclassify certain regions of
the state for SO 2 emergency episode planning and remove obsolete language from the Nevada SIP. We are taking comments on this proposal and plan to
follow with a final action.

**DATES :**  Written comments must be received on or before June 19, 2015.

1 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. 2 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 25163–25165, May 12, 2005 (explaining relationship between timing requirement of section 110(a)(2)(D) versus section 110(a)(2)(I)).

3 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 submittal of certain types of SIP submittals in designated nonattainment areas for various pollutants. Note,

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

I. EPA’s Approach to the Review of
Infrastructure SIP Submissions

EPA is acting upon several SIP
submittals from Nevada that address the infrastructure requirements of CAA sections 110(a)(1) and 110(a)(2) for the 2008 ozone, 2010 NO 2 , and 2010 SO 2 NAAQS. The requirement for states to make a SIP submittal of this type arises out of CAA section 110(a)(1). Pursuant to section 110(a)(1), states must make SIP submittals ‘‘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 submittals are to provide for the ‘‘implementation, maintenance, and enforcement’’ of such NAAQS. The statute directly imposes on states the duty to make these SIP submittals, and the requirement to make the submittals 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’’
submittal must address.

EPA has historically referred to these SIP submittals made for the purpose of satisfying the requirements of CAA sections 110(a)(1) and 110(a)(2) as
‘‘infrastructure SIP’’ submittals. Although the term ‘‘infrastructure SIP’’ does not appear in the CAA, EPA uses the term to distinguish this particular type of SIP submittal from submittals that are intended to satisfy other SIP requirements under the CAA, such as

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

Section 110(a)(1) addresses the timing and general requirements for infrastructure SIP submittals, and section 110(a)(2) provides more details concerning the required contents of these submittals. 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. 1 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 submittals provided in section 110(a)(2) contains ambiguities concerning what is required for inclusion in an
infrastructure SIP submittal.

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 submittals for a given new or revised NAAQS. One example of ambiguity is that section 110(a)(2) requires that ‘‘each’’ SIP
submittal 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. 2 Section 110(a)(2)(I) pertains to nonattainment SIP requirements and part D addresses when attainment plan SIP submittals to
address nonattainment area requirements are due. For example, section 172(b) requires EPA to establish a schedule for submittal 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. 3 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 submittal.

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 submittal, and whether EPA must act upon such SIP submittal 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 submittals separately addressing
infrastructure SIP elements for the same NAAQS. If states elect to make such multiple SIP submittals to meet the infrastructure SIP requirements, EPA
can elect to act on such submittals either individually or in a larger
combined action. 4 Similarly, EPA

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).

5 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.

6 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. 7 EPA notes, however, that nothing in the CAA requires EPA to provide guidance or to promulgate regulations for infrastructure SIP submittals. The CAA directly applies to states and requires the submittal of infrastructure SIP submittals, regardless of whether or not EPA provides guidance or regulations pertaining to such submittals. EPA elects to issue such guidance in order to assist states, as appropriate.

8 ‘‘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. 9 EPA’s September 13, 2013, guidance did not make recommendations with respect to
infrastructure SIP submittals 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. interprets the CAA to allow it to take action on the individual parts of one larger, comprehensive infrastructure SIP submittal for a given NAAQS without
concurrent action on the entire submittal. For example, EPA has
sometimes elected to act at different
times on various elements and subelements of the same infrastructure SIP
submittal. 5

Ambiguities within sections 110(a)(1) and 110(a)(2) may also arise with respect to infrastructure SIP submittal 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 submittals for each NAAQS therefore could be different. For example, the monitoring requirements that a state might need to meet in its infrastructure SIP submittal for purposes of section 110(a)(2)(B) could be very different for different pollutants, for example because the content and scope of a
state’s infrastructure SIP submittal to meet this element might be very different for an entirely new NAAQS than for a minor revision to an existing NAAQS. 6

EPA notes that interpretation of section 110(a)(2) is also necessary when EPA reviews other types of SIP submittals required under the CAA. Therefore, as with infrastructure SIP submittals, EPA also has to identify and interpret the relevant elements of section 110(a)(2) that logically apply to these other types of SIP submittals. For example, section 172(c)(7) requires that attainment plan SIP submittals required by part D have to meet the ‘‘applicable requirements’’ of section 110(a)(2). Thus, for example, attainment plan SIP submittals 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 submittals required by part D would not need to meet the portion of section 110(a)(2)(C) that pertains to the air quality prevention of significant deterioration (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 submittal 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 submittal. In other words, EPA assumes that Congress could not have intended that each and every SIP submittal, 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 submittals 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 submittals for particular
elements. 7 EPA most recently issued guidance for infrastructure SIPs on September 13, 2013 (2013 Infrastructure SIP Guidance). 8 EPA developed thisdocument to provide states with up-todate guidance for infrastructure SIPs for any new or revised NAAQS. Within this guidance, EPA describes the duty of
states to make infrastructure SIP
submittals 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 submittals. 9 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 submittals need to
address certain issues and need not address others. Accordingly, EPA
reviews each infrastructure SIP submittal 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 submittals. 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
submittals to ensure that the state’s SIP appropriately addresses the requirements of section 110(a)(2)(E)(ii)
and section 128. The 2013 Infrastructure SIP 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
submittals 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 submittals 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


### 28896 Federal Register / Vol. 80, No. 97 / Wednesday, May 20, 2015 / Proposed Rules

10 By contrast, EPA notes that if a state were to include a new provision in an infrastructure SIP submittal 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. 11 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,’’ 76 FR 21639, April 18, 2011.

12 EPA has used this authority to correct errors in past actions on SIP submittals 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).

13 See, e.g., EPA’s disapproval of a SIP submittal from Colorado on the grounds that it would have included a director’s discretion provision inconsistent with CAA requirements, including section 110(a)(2)(A). See, e.g., 75 FR 42342 at 42344, July 21, 2010 (proposed disapproval of director’s discretion provisions); 76 FR 4540, January 26, 2011 (final disapproval of such provisions). contained in part C, title I of the Act and EPA’s PSD regulations. Structural PSD program requirements include provisions necessary for the PSD program to address all regulated sources and regulated NSR pollutants, including greenhouse gases (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 submittal focuses on assuring that the state’s SIP 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 a SIP-approved minor NSR program and whether the program addresses the pollutants relevant to that NAAQS. In the context of acting on an infrastructure SIP submittal, 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 submittal 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 submittal without scrutinizing the totality of the existing SIP for such potentially deficient provisions and may approve
the submittal even if it is aware of such existing provisions. 10 It is important to note that EPA’s approval of a state’s
infrastructure SIP submittal should notbe construed as explicit or implicit reapproval of any existing potentially deficient provisions that relate to the three specific issues just described.

EPA’s approach to review of
infrastructure SIP submittals is to identify the CAA requirements that are logically applicable to that submittal. EPA believes that this approach to the review of a particular infrastructure SIP submittal 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 submittal. 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 Infrastructure SIP 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 submittal 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. 11 Section 110(k)(6) authorizes EPA to correct errors in past actions, such as past approvals of SIP submittals. 12 Significantly, EPA’s determination that

an action on a state’s infrastructure SIP submittal 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 submittal, 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. 13

17 Utility Air Regulatory Group v. Environmental Protection Agency, 134 S.Ct. 2427. II. Background

A. Statutory Framework

Section 110(a)(1) of the CAA requires
states to make a SIP submission within 3 years after the promulgation of a new or revised primary NAAQS. Section 110(a)(2) includes a list of specific elements that ‘‘[e]ach such plan’’ submission must include. Many of the section 110(a)(2) SIP elements relate to the general information and authorities
that constitute the ‘‘infrastructure’’ of a state’s air quality management program
and SIP submittals that address these requirements are referred to as
‘‘infrastructure SIPs.’’ These infrastructure SIP elements required by section 110(a)(2) are as follows:

• Section 110(a)(2)(A): Emission
limits and other control measures.

• Section 110(a)(2)(B): Ambient air quality monitoring/data system.

• Section 110(a)(2)(C): Program for
enforcement of control measures and regulation of new and modified stationary sources.

• Section 110(a)(2)(D)(i): Interstate pollution transport.

• Section 110(a)(2)(D)(ii): Interstate and international pollution abatement.

• Section 110(a)(2)(E): Adequate resources and authority, conflict of interest, and oversight of local and regional government agencies.

• Section 110(a)(2)(F): Stationary source monitoring and reporting.

• Section 110(a)(2)(G): Emergency episodes.

• Section 110(a)(2)(H): SIP revisions.

• Section 110(a)(2)(J): Consultation with government officials, public notification, PSD, and visibility protection.

• Section 110(a)(2)(K): Air quality modeling and submittal of modeling
data.

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

• Section 110(a)(2)(M): Consultation/ participation by affected local entities.

Two elements identified in section110(a)(2) are not governed by the threeyear submittal deadline of section 110(a)(1) and are therefore not
addressed in this action. These two elements are: Section 110(a)(2)(C) to the extent it refers to permit programs required under part D (nonattainment NSR), and section 110(a)(2)(I), pertaining to the nonattainment planning requirements of part D. As a result, this action does not address
infrastructure for the nonattainment NSR portion of section 110(a)(2)(C) or the whole of section 110(a)(2)(I).

B. Regulatory Background

Between 1997 and 2012, EPA promulgated a series of new or revised NAAQS for ozone, NO 2 , and SO 2 , triggering a requirement for states to submit infrastructure SIPs. The NAAQS addressed by this infrastructure SIP proposal include the following:

• 2008 ozone NAAQS, which revised
the 8-hour ozone standards to 0.075

ppm. 14

• 2010 NO 2 NAAQS, which revised the primary 1971 NO 2 annual standard of 53 parts per billion (ppb) by supplementing it with a new 1-hour average NO 2 standard of 100 ppb, and retained the secondary annual standard of 53 ppb. 15

• 2010 SO 2 NAAQS, which established a new 1-hour average SO 2 standard of 75 ppb, retained the secondary 3-hour average SO 2 standard of 500 ppb, and established a mechanism for revoking the primary
1971 annual and 24-hour SO 2 standards. 16

C. Changes to the Application of PSD Permitting Requirements With GHGs

With respect to Elements (C) and (J), EPA interprets the Clean Air Act to require each state to make an
infrastructure SIP submission for a new or revised NAAQS that demonstrates that the air agency has a complete PSD permitting program meeting the current requirements for all regulated NSR pollutants. The requirements of Element D(i)(II) may also be satisfied by demonstrating the air agency has a complete PSD permitting program correctly addressing all regulated NSR pollutants. Nevada has shown that it currently has a PSD program in place that covers all regulated NSR pollutants, including greenhouse gases (GHGs), with the exception of the deficiencies in the NDEP and Washoe County portions of the SIP, described elsewhere in this
document.

On June 23, 2014, the United States Supreme Court issued a decision addressing the application of PSD permitting requirements to GHG

emissions. 17 The Supreme Court said that the EPA may not treat GHGs as an air pollutant for purposes of determining whether a source is a major source required to obtain a PSD permit.
The Court also said that the EPA could continue to require that PSD permits, otherwise required based on emissions of pollutants other than GHGs, contain limitations on GHG emissions based on the application of Best Available Control Technology (BACT). In order to act consistently with its understanding of the Court’s decision pending further judicial action to effectuate the decision, the EPA is not continuing to apply EPA regulations that would require that SIPs include permitting requirements that the Supreme Court found impermissible. Specifically, EPA is not applying the requirement that a state’s SIP-approved PSD program require that sources obtain PSD permits when GHGs are the only pollutant (i) that the source emits or has the potential to emit above the major source thresholds, or (ii) for which there is a significant emissions increase and a significant net emissions increase from a modification ( e.g. 40 CFR 51.166(b)(48)(v)). EPA anticipates a need to revise federal PSD rules in light of the Supreme Court opinion. In addition, EPA anticipates that manystates will revise their existing SIPapproved PSD programs in light of the Supreme Court’s decision. The timing and content of subsequent EPA actions with respect to the EPA regulations and state PSD program approvals are expected to be informed by additional legal process before the United States Court of Appeals for the District of Columbia Circuit. At this juncture, EPA is not expecting states to have revised their PSD programs for purposes of
infrastructure SIP submissions and is only evaluating such submissions to assure that the state’s program correctly
addresses GHGs consistent with the Supreme Court’s decision.

At present, EPA has determined the Clark County SIP is sufficient to satisfy Elements C, D(i)(II), and J with respect to GHGs because the PSD permitting program previously approved by EPA into the SIP continues to require that PSD permits (otherwise required based on emissions of pollutants other than GHGs) contain limitations on GHG emissions based on the application of BACT. Although the SIP-approved Clark County PSD permitting program may currently contain provisions that are no longer necessary in light of the Supreme Court decision, this does not render the
infrastructure SIP submission inadequate to satisfy Elements C, (D)(i)(II), and J. The SIP contains the necessary PSD requirements at this time, and the application of those requirements is not impeded by the presence of other previously-approved provisions regarding the permitting of
sources of GHGs that EPA does not consider necessary at this time in light of the Supreme Court decision. Accordingly, the Supreme Court


### 28898 Federal Register / Vol. 80, No. 97 / Wednesday, May 20, 2015 / Proposed Rules

decision does not affect EPA’s proposed approval of Clark County’s infrastructure SIP as to the requirements of Elements C, D(i)(II), and J.

III. State Submittal and EPA Action

The Nevada Department of Environmental Protection (NDEP) has
submitted several infrastructure SIP submittals pursuant to EPA’s promulgation of specific NAAQS, including:

Ozone

• The Nevada Division of
Environmental Protection Portion of the Nevada State Implementation Plan for the 2008 Ozone NAAQS: Demonstration of Adequacy April 10, 2013.

• State Implementation Plan Revision
to Meet the Ozone Infrastructure SIP Requirements of the Clean Air Act section 110(a)(2), Clark County, Nevada, February 2013.

• The Washoe County Portion of the Nevada State Implementation Plan for the 2008 Ozone NAAQS: Demonstration of Adequacy, February 28, 2013.

NO 2

• NDEP letter to EPA, dated May 9, 2013 and Washoe County letter, dated April 26, 2013, containing the Approved Minutes of the February 28, 2013 public hearing and the Certificate of Adoption.

• The Nevada Division of
Environmental Protection Portion of the Nevada State Implementation Plan for the 2010 Nitrogen Dioxide Primary NAAQS: Demonstration of Adequacy and appendices, January 18, 2013.

• State Implementation Plan Revision to Meet the Nitrogen Dioxide Infrastructure SIP Requirements of the Clean Air Act section 110(a)(2), and attachments Clark County, Nevada
December 2012.

• The Washoe County Portion of the Nevada State Implementation Plan to Meet the Nitrogen Dioxide Infrastructure SIP Requirements of Clean Air Act section 110(a)(2) (draft document) and attachments, January 24,

2014.

SO 2

• The Nevada Division of
Environmental Protection Portion of the Nevada State Implementation Plan for the 2010 Sulfur Dioxide Primary NAAQS, and appendices, June 3, 2013.

• State Implementation Plan Revision
to Meet the Sulfur Dioxide Infrastructure SIP Requirements of the Clean Air Act section 110(a)(2), and attachments Clark County, Nevada, May

2013.

• The Washoe County Portion of the Nevada State Implementation Plan to Meet the Sulfur Dioxide Infrastructure SIP Requirements of Clean Air Act section 110(a)(2), and attachments, March 28, 2013.

We find that these submittals meet the procedural requirements for public participation under CAA section 110(a)(2) and 40 CFR 51.102. We are proposing to act on all of these submittals since they collectively
address the infrastructure SIP requirements for the NAAQS addressed by this proposed rule. We refer to them collectively herein as ‘‘Nevada’s
Infrastructure SIP Submittals.’’

IV. EPA’s Evaluation and Proposed

Action

A. Proposed Approvals and Partial Approvals

We have evaluated Nevada’s
Infrastructure SIP Submittals and the existing provisions of the Nevada SIP for compliance with the infrastructure SIP requirements (or ‘‘elements’’) of CAA section 110(a)(2) and applicable regulations in 40 CFR part 51 (‘‘Requirements for Preparation, Adoption, and Submittal of State Implementation Plans’’). The Technical Support Document (TSD), which is available in the docket to this action, includes our evaluation for many elements, as well as our evaluation of various statutory and regulatory provisions. For some elements, it refers to older TSDs for prior Nevada Infrastructure SIPs, which have also
been included in the docket.

Based upon this analysis, we propose to approve the 2008 Ozone, 2010 NO 2, and 2010 SO 2 Nevada Infrastructure SIP with respect to the following Clean Air Act requirements:

• Section 110(a)(2)(A): Emission
limits and other control measures.

• Section 110(a)(2)(B): Ambient air quality monitoring/data system.

• Section 110(a)(2)(C) (in part): Program for enforcement of control measures and regulation of new stationary sources (full approval for Clark County).

• Section 110(a)(2)(D) (in part, see below): Interstate Pollution Transport.

D Section 110(a)(2)(D)(i)(II) (in part)— significant contribution to nonattainment, or prongs 1 and 2 (full approval of NDEP, Clark County and Washoe County for the NO2 NAAQS).

D Section 110(a)(2)(D)(i)(II) (in part)— interference with maintenance, or prong 3 (full approval for Clark County).

D Section 110(a)(2)(D)(i)(II) (full approval)—visibility transport, or prong

4.

D Section 110(a)(2)(D)(ii) (in part)— interstate pollution abatement and international air pollution (full approval for Clark County).

• Section 110(a)(2)(E): Adequate resources and authority, conflict of interest, and oversight of local governments and regional agencies.

• Section 110(a)(2)(F): Stationary source monitoring and reporting.

• Section 110(a)(2)(G): Emergency episodes.

• Section 110(a)(2)(H): SIP revisions.

• Section 110(a)(2)(J) (in part): Consultation with government officials, public notification, and prevention of significant deterioration (PSD) and visibility protection (full approval for Clark County).

• Section 110(a)(2)(K): Air quality modeling and submission of modeling
data.

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

• Section 110(a)(2)(M): Consultation/ participation by affected local entities.

EPA is taking no action on Interstate Transport—significant contribution to nonattainment for NDEP, Clark County and Washoe County on the Ozone and

SO 2 NAAQS (section 110(a)(2)(D)(i)(II)).

B. Proposed Partial Disapprovals

EPA proposes to disapprove Nevada’s
Infrastructure SIP Submittals with respect to the following infrastructure SIP requirements:

• Section 110(a)(2)(C) (in part): Program for enforcement of control measures and regulation of new and modified stationary sources (for all NAAQS addressed by this proposed rule and covered by the NDEP and Washoe County PSD permitting programs).

• Section 110(a)(2)(D)(i)(II) (in part, see below): Interstate pollution transport,

D Section 110(a)(2)(D)(i)(II) (in part)— interference with maintenance, or prong 3 (disapproved for all NAAQS addressed by this proposed rule and covered by the NDEP and Washoe County PSD permitting programs).

D Section 110(a)(2)(D)(ii) (in part)— interstate pollution abatement and international air pollution (disapproved for all NAAQS addressed by this proposed rule and covered by the NDEP and Washoe County PSD permitting programs).

• Section 110(a)(2)(J) (in part): Consultation with government officials, public notification, PSD, and visibility protection (for all NAAQS addressed by this proposed rule and covered by the NDEP and Washoe County PSD permitting programs).

As explained more fully in our TSD, we are proposing to disapprove the NDEP and Washoe County portions of
Nevada’s Infrastructure Submittals with


### 28899 Federal Register / Vol. 80, No. 97 / Wednesday, May 20, 2015 / Proposed Rules

18 EPA fully delegated the implementation of the federal PSD programs to NDEP on October 19, 2004 (‘‘Agreement for Delegation of the Federal Prevention of Significant Deterioration (PSD) Program by the United States Environmental Protection Agency, Region 9 to the Nevada Division of Environmental Protection’’), as updated on September 15, 2011 and November 7, 2012, and to Washoe County on March 13, 2008 (‘‘Agreement for Delegation of the Federal Prevention of Significant Deterioration (PSD) Program by the United States Environmental Protection Agency, Region 9 to the Washoe County District Health Department’’).

19 Federal Air Quality Control Regions, U.S. EPA, January 1972 <http://nepis.epa.gov/Exe/ZyPDF.cgi/ P10053PA.PDF?Dockey=P10053PA.PDF > (last visited April 1, 2015). 20 40 CFR 51.151 and 51.152.

21 40 CFR 51.150(c).

22 40 FR 5508.

23 67 FR 17939. 24 SO 2 monitoring is not required for the Nevada Intrastate Air Quality Control Region, because it’s population weighted exposure index does not exceed 5000 (million person-tons per year of SO 2 ), per 40 CFR part 58, appendix D 4.4.2.

25 40 FR 5508. respect to the PSD-related requirements of sections 110(a)(2)(C), 110(a)(2)(D)(i)(II), 110(a)(2)(D)(ii), and the PSD requirements of section 110(a)(2)(J). The Nevada SIP does not fully satisfy the statutory and regulatory requirements for PSD permit programs under part C, title I of the Act, because NDEP and Washoe County currently implement the Federal PSD program in 40 CFR 52.21 for all regulated NSR pollutants, pursuant to delegation agreements with EPA. See 40 CFR

52.1485. 18 Accordingly, although the
Nevada SIP remains deficient with respect to PSD requirements in both the NDEP and Washoe County portions of the SIP, these deficiencies are adequately addressed in both areas by the federal PSD program and do not create new FIP obligations.

In EPA’s evaluation of Nevada’s
Infrastructure SIP Submittal for Lead (Pb), the requirements under sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) and 110(a)(2)(J) regarding Clark County’s PSD permitting program, specifically
PSD increments for PM 2.5 , initiated a requirement for the development of a Federal Implementation Plan (FIP) or sanctions. This deficiency has been addressed by the recent changes to the Clark County PSD permitting program,
as discussed in Element C of the TSD.

C. Defining the Nevada Intrastate Air Quality Control Region

In reviewing the Nevada SIP Infrastructure submittal for compliance with CAA section 110(a)(2)(G), as discussed in section D below, we noted that the Nevada Intrastate Air Quality Control Region has not been defined in subpart B of 40 CFR part 81. The emergency episode priority classifications for the Region is provided by 40 CFR 52.1471 for many NAAQS. Additionally, EPA identified
the counties of the Nevada Intrastate Region in a 1972 EPA report titled: Federal Air Quality Control Regions. 19 To rectify the apparent Federal Register omission, we are proposing to define the Nevada Intrastate Air Quality Control Region in subpart B of 40 CFR part 81,
consistent with Federal Air Quality Control Regions, as comprised of the following counties: Elko, Humboldt, Pershing, Lander, Eureka, White Pine, Lincoln, Nye, Esmeralda, Mineral, and Churchill. On its own, this proposed change does not alter the priority classification of the Region for emergency episode purposes.

D. Proposed Approval of Reclassification Requests for Emergency Episode Planning

NDEP’s portion of Nevada’s SO 2 Infrastructure Submittal requested that EPA reclassify the Nevada Intrastate Air Quality Region with respect to the emergency episode planning requirements of CAA section 110(a)(2)(G) and 40 CFR part 51, subpart H. The priority thresholds for classification of regions are listed in 40 CFR 51.150 while the specific classifications of air quality control regions in Nevada are listed at 40 CFR 52.1471. Consistent with the provisions of 40 CFR 51.153, reclassification of an air quality control region must rely on the most recent three years of air quality data. Regions classified Priority I, IA, or II are required to have SIP-approved emergency episode contingency plans, while those classified Priority III are not required to have plans. 20 We interpret 40 CFR 51.153 as establishing the means for states to review air quality data and request a higher or lower classification for any given region and as providing the regulatory basis for EPA to reclassify such regions, as appropriate, under the authorities of CAA sections 110(a)(2)(G) and 301(a)(1).

The Nevada Intrastate Air Quality Control Region is classified as priority
IA for SO 2 . Priority IA means the region is classified as Priority I ‘‘primarily because of emissions from a single point

source.’’ 21 As our TSD further clarifies, the point source appears to have been the copper smelter in McGill, Nevada, within the Steptoe Valley, operated by the Kennecott Minerals Company. The Kennecott smelter was the only major
source of SO 2 emissions within the Nevada Interstate Region when the priority classifications were established

in 1980. 22

Our attainment finding for Steptoe Valley (SO 2) nonattainment area stated that the Kennecott facility ceased operation in 1983, removed all smelting equipment in 1987, and demolished the facility’s stack in 1993. 23 It continued on to state ‘‘ambient air quality monitoring from 1979 to 1983 indicates there were no violations during the last years of the smelter operation.’’ NDEP
has not collected SO 2 monitoring data since 1983, nor are they currently required to do so. 24 Based on the information above and presented in our TSD, we are proposing to approve Nevada’s request to reclassify the Nevada Intrastate Air Quality Region to Priority III for SO 2 emergency episode planning.

We also evaluated the Las Vegas Intrastate Air Quality Control Region (i.e. Clark County), which is also currently classified as Priority IA for

SO 2. Their ambient air quality data for 2011–2013 does not exceed the Priority
II level of 260–455 mg/m 3 set at 40 CFR 51.150(d)(1). Therefore, based on the last three years of available data, we are proposing to reclassify the Las Vegas Intrastate Region to Priority III for SO 2

. E. Proposed Removal of Historic SIP

Provisions

NDEP also requested that EPA remove paragraphs (a) and (b) of 40 CFR 52.1475, ‘‘Control strategy and regulations: Sulfur oxides.’’ This section
was added to the Nevada SIP ‘‘. . . to promulgate substitute regulations for the
control of SO 2 at the Kennecott Copper Corporation Smelter, McGill,
Nevad a . . .’’ because we had disapproved Nevada’s proposed SO 2 emission controls for the Kennecott
smelter. 25 40 CFR 52.1475 no longer applies since the Kennecott smelter is
nonexistent and the area was redesignated as attainment. Since the provision serves no purpose beyond providing historic information, we are proposing to remove 40 CFR 52.1475
from the Nevada SIP.

F. Request for Public Comments

EPA is soliciting public comments on
the issues discussed in this document or
on other relevant matters. We will accept comments from the public on this proposal for the next 30 days. We
will consider these comments before taking final action.

V. Statutory and Executive Order

Reviews

Executive Order 12866: Regulatory Planning and Review

This action is not a ‘‘significant regulatory action’’ under the terms of


### 28900 Federal Register / Vol. 80, No. 97 / Wednesday, May 20, 2015 / Proposed Rules

Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under the EO.

Paperwork Reduction Act

This action does not impose an
information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. , because this proposed partial approval and partial disapproval of SIP revisions under CAA
section 110 will not in-and-of itself create any new information collection burdens but simply proposes to approve certain State requirements, and to disapprove certain other State requirements, for inclusion into the SIP. Burden is defined at 5 CFR 1320.3(b).

Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA) generally requires an agency to conduct a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements unless the agency certifies that the rule will not have a significant economic impact on
a substantial number of small entities. Small entities include small businesses, small not-for-profit enterprises, and small governmental jurisdictions. For purposes of assessing the impacts of this rule on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration’s (SBA) regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not
dominant in its field.

After considering the economic impacts of this proposed rule, we certify that this proposed action will not have a significant impact on a substantial number of small entities. This proposed rule does not impose any requirements or create impacts on small entities. This proposed partial SIP approval and partial SIP disapproval under CAA
section 110 will not in-and-of itself create any new requirements but simply proposes to approve certain State requirements, and to disapprove certain other State requirements, for inclusion into the SIP. Accordingly, it affords no opportunity for EPA to fashion for small entities less burdensome compliance or reporting requirements or timetables or exemptions from all or part of the rule. Therefore, this action will not have a significant economic impact on a
substantial number of small entities.

We continue to be interested in the potential impacts of this proposed rule on small entities and welcome
comments on issues related to such impacts.

Unfunded Mandates Reform Act

This action contains no Federal mandates under the provisions of Title
II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531– 1538 for State, local, or tribal governments or the private sector. EPA has determined that the proposed partial approval and partial disapproval
action does not include a Federal mandate that may result in estimated costs of $100 million or more to either State, local, or tribal governments in the aggregate, or to the private sector. Thisaction proposes to approve certain preexisting requirements, and to disapprove certain other pre-existing requirements, under State or local law, and imposes no new requirements. Accordingly, no additional costs to State, local, or tribal governments, or to the private sector, result from this proposed action.

Executive Order 13132: Federalism

Executive Order 13132, entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure ‘‘meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.’’ ‘‘Policies that have federalism implications’’ is defined in
the Executive Order to include regulations that have ‘‘substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.’’

This action does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, because it merely proposes to approve certain State requirements, and to disapprove certain other State requirements, for
inclusion into the SIP and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. Thus, Executive Order 13132 does not apply to this

action.

Executive Order 13175: Coordination
With Indian Tribal Governments

This action does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP on which EPA is proposing action would not apply in Indian country located in the state, and EPA notes that it will not impose
substantial direct costs on tribal governments or preempt tribal law. Thus, Executive Order 13175 does not apply to this proposed action.

Executive Order 13045: Protection of
Children From Environmental Health Risks and Safety Risks

EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern health or safety risks, such that the analysis required
under section 5–501 of the Executive Order has the potential to influence the regulation. This proposed action is not subject to Executive Order 13045 because it is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997). This proposed partial approval and partial disapproval under
CAA section 110 will not in-and-of itself create any new regulations but simply proposes to approve certain State requirements, and to disapprove certain other State requirements, for inclusion
into the SIP.

Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use

This proposed rule is not subject to Executive Order 13211 (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under
Executive Order 12866.

National Technology Transfer and
Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (‘‘NTTAA’’), Public Law 104–113, 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities
unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards ( e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary
consensus standards.

The EPA believes that this proposed action is not subject to requirements of Section 12(d) of NTTAA because application of those requirements would
be inconsistent with the Clean Air Act.


### 28901 Federal Register / Vol. 80, No. 97 / Wednesday, May 20, 2015 / Proposed Rules

Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Population

Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.

EPA lacks the discretionary authority to address environmental justice in this proposed rulemaking.

**ACTION :**  Proposed rule.

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve
two revisions to the New Mexico State Implementation Plan (SIP) to update the Albuquerque-Bernalillo County Prevention of Significant Deterioration (PSD) SIP permitting program consistent with federal requirements. New Mexico submitted the Albuquerque-Bernalillo County PSD SIP permitting revisions on July 26, 2013, and March 4, 2015, which included a request for parallel processing of the submitted 2015
revisions. These submittals contain revisions to address the requirements of the EPA’s May 2008, July 2010, and
October 2012 PM 2.5 PSD Implementation Rules and to incorporate revisions consistent with the EPA’s March 2011 Fugitives Interim Rule, July 2011 Greenhouse Gas (GHG) Biomass Deferral Rule, and July 2012 GHG Tailoring Rule Step 3 and GHG PALs Rule. The EPA is proposing to
find that these revisions to the New
Mexico SIP meet the Federal Clean Air Act (the Act or CAA) and EPA regulations, and are consistent with EPA policies. We are proposing this action under section 110 and part C of title I of the Act. The EPA is not approving
these rules within the exterior
boundaries of a reservation or other areas within any Tribal Nation’s jurisdiction.
