Public Comment and Final Action IV. Statutory and Executive Order Reviews I. The State’s Submittals A. Which rules did the State submit? On January 3, 2014, the Nevada Division of Environmental Protection (NDEP) submitted a revision to the Nevada State Implementation Plan (SIP) to EPA for approval under section 110(k) of the Clean Air Act (CAA or ‘‘Act’’). NDEP’s submittal includes certain amended State rules [i.e., certain sections of Nevada Administrative Code (NAC)] that relate to applications for, and issuance of, permits for stationary sources [a process referred to herein as ‘‘New Source Review’’ (NSR)].1 The specific amended rules submitted on January 3, 2014 are NAC sections 445B.22097 (‘‘Standards of quality for ambient air’’) and 445B.308 (‘‘Prerequisites and conditions for issuance of certain operating permits; compliance with applicable state implementation plan’’).2 In addition to the amended rules, NDEP’s January 3, 2014 submittal contains evidence of public notice and adoption of the amendments to the rules by the Nevada State Environmental Commission (SEC) on December 4, 2013, and a copy of the filing by the Legislative Counsel Bureau of the amended rules with the Nevada Secretary of State on December 23, 2013 making the amendments effective on that date. On June 5, 2014, NDEP submitted a second SIP revision including further amendments to NAC section 445B.22097 (‘‘Standards of quality for ambient air’’) and amendments to NAC section 445B.311 (‘‘Environmental evaluation: Contents; consideration of good engineering practice stack 62847 height’’). We consider the June 5, 2014 submittal of NAC section 445B.22097 as superseding the submittal of that rule on January 3, 2014. NDEP’s June 5, 2014 submittal includes a technical support document in which NDEP provides its explanation for how the amended rules meet CAA requirements. NDEP’s June 5, 2014 submittal also contains evidence of public notice and adoption of the amendments to the rules by the Nevada SEC on May 2, 2014. On July 15, 2014, NDEP provided documentation that the most recent amendments to NAC sections 445B.22097 and 445B.311 were filed by the Legislative Counsel Bureau with the Nevada Secretary of State on June 23, 2014 and are thus in effect as of that date. Table 1 below lists the rules that were submitted by NDEP on January 3, 2014 and June 5, 2014 and on which EPA is taking action today. The three submitted rules represent updated versions of rules already approved into the Nevada SIP. We last approved NAC section 445B.22097 at 71 FR 15040 (March 27, 2006), and last approved NAC sections 445B.308 and 445B.311 at 77 FR 59321 (September 27, 2012). Upon the effective date of today’s final action, the versions of the rules that we previously approved will be superseded in the applicable SIP by the versions of the rules approved today.

What is the regulatory context? Under sections 107 and 109 of the CAA, the EPA establishes national ambient air quality standards (NAAQS or standards) and designates all areas of the country as attainment, nonattainment, or unclassifiable for the various NAAQS. To date, EPA has established NAAQS for such pervasive pollutants as ozone, carbon monoxide, nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter, and lead (Pb). 1 We note that the stationary source permitting rules that are the subject of this rule are not related to the requirements for pre-construction review and permitting of major sources or major modifications under part C (‘‘Prevention of Significant VerDate Sep<11>2014 16:03 Oct 20, 2014 Jkt 235001 Submittal date 05/02/14 12/04/13 06/05/14 01/03/14 05/02/14 06/05/14 With respect to particulate matter, EPA has established NAAQS for particulate matter with an aerodynamic diameter generally less than or equal to 10 microns (PM10) and for particulate matter with an aerodynamic diameter generally less than or equal to 2.5 microns (PM2.5). Under section 110 of the CAA, each state is required to develop a state implementation plan (SIP) to implement, maintain, and enforce the NAAQS. Among the content requirements for SIPs is the requirement to develop and submit (for EPA approval) a program to provide for the regulation of the modification and construction of any stationary source as necessary to assure that the NAAQS are achieved, including a permit program as required in parts C and D of title I of the CAA. See CAA section 110(a)(2)(C). The permit programs required under parts C and D of title I of the CAA are referred to as Deterioration of air quality’’) or part D (‘‘Plan requirements for nonattainment areas’’) of title I of the Clean Air Act. 2 By letter dated January 28, 2014, NDEP withdrew amended versions of NAC sections 445B.308 and 445B.311 that had been submitted on January 3, 2014 from EPA consideration as revisions to the Nevada SIP, but, by letter dated September 17, 2014, NDEP reinstated the January 3, 2014 submittal of NAC 445B.308. PO 00000 Frm 00051 Fmt 4700 Sfmt 4700 E:\FR\FM\21OCR1.SGM 21OCR1 62848 Federal Register / Vol. 79, No. 203 / Tuesday, October 21, 2014 / Rules and Regulations the Prevention of Significant Deterioration (PSD) permit program and the Nonattainment New Source Review (NNSR) permit program, respectively. Collectively, the PSD and NNSR programs constitute a state’s ‘‘major source’’ permit program, under which applications for construction and operation of new major stationary sources and major modifications of such sources are reviewed for compliance with the PSD and NNSR requirements. New or modified stationary sources that are not major sources or major modifications are referred to as minor sources (or minor modifications), and the program for review of the applications for construction and operation of such sources is referred to as the minor source permit program or ‘‘minor NSR.’’ Today’s action relates to three rules promulgated by the Nevada SEC as part of the State of Nevada’s minor NSR program, which is administered by NDEP. NDEP’s stationary source jurisdiction extends statewide with respect to power plants which generate electricity by using steam produced by the burning of fossil fuel, but does not include Clark or Washoe counties with respect to all other stationary sources. Over the years, the State of Nevada has adopted and implemented, and EPA has approved, rules governing minor NSR. Our most recent action on Nevada’s minor source NSR rules was published on September 27, 2012 (77 FR 59321). In the September 27, 2012 final rule, we issued a limited approval and limited disapproval of a comprehensive update to the State’s minor source NSR rules. We did so because, although we found that the new or amended rules met most of the applicable requirements for such NSR programs and that the rules improved the existing SIP, we also found certain deficiencies that prevented full approval. Specifically, we indicated that the minor NSR rules did not address the new or revised NAAQS for PM2.5 and Pb and must be revised accordingly.3 In addition, we recognized that EPA had recently established new or revised NAAQS for NO2 and SO2,4 and while the State still asabaliauskas on DSK5VPTVN1PROD with RULES 3 In 1997 (62 FR 38652, July 18, 1997), EPA first established annual and 24-hour PM2.5 NAAQS of 15 micrograms per cubic meter (mg/m3) and 65 mg/m3, respectively. In 2006 (71 FR 61144, October 17, 2006), EPA lowered the 24-hour PM2.5 NAAQS to 35 mg/m3. For simplicity, we refer herein to the 1997 annual PM2.5 and 2006 24-hour PM2.5 NAAQS collectively as the ‘‘2006 PM2.5 NAAQS.’’ In 2008 (73 FR 66964, November 12, 2008), EPA lowered the Pb NAAQS to 0.15 mg/m3, rolling 3-month average (referred to herein as the ‘‘2008 Pb NAAQS’’). 4 In 2010 (75 FR 6474, February 9, 2010), EPA established a one-hour NO2 NAAQS of 100 parts VerDate Sep<11>2014 16:03 Oct 20, 2014 Jkt 235001 had additional time to amend its NSR rules to address the revised NAAQS for these pollutants, we encouraged the Nevada SEC to make any necessary revisions to the State’s NSR rules to address the revised NAAQS for those two pollutants as well, and the NDEP to submit the NSR rules, as revised, to us as a SIP revision. C. What is the purpose of this direct final rule? The Nevada SEC amended NAC section 445B.308 to eliminate an outdated provision and to renumber the paragraphs in the rule accordingly. The Nevada SEC amended NAC sections 445B.22097 and 445B.311 to ensure that the new or revised NAAQS for PM2.5, Pb, NO2 and SO2 are taken into account in minor NSR permitting decisions. The Nevada SEC also updated NAC section 445B.22097 to reflect the most recent ozone NAAQS.5 The purpose of this direct final rule is to present our evaluation under the CAA and EPA’s regulations of the amended NSR rules submitted by NDEP on January 3, 2014 and June 5, 2014. II. EPA’s Evaluation A. How is EPA evaluating the rules? EPA has reviewed the rules submitted on January 3, 2014 and June 5, 2014 for compliance with the CAA requirements for SIPs in general set forth in CAA section 110(a)(2), for compliance with applicable EPA regulations for stationary source permitting programs in 40 CFR part 51, sections 51.160 through 51.164, and also for compliance with CAA requirements for SIP revisions in CAA section 110(l).6 As described below, EPA has found that the amended rules meet all applicable requirements and is thus taking direct final action to approve them as revisions to the Nevada SIP. B. Do the rules meet the evaluation criteria? As to procedural requirements for SIPs and SIP revisions, we find that, per billion (ppb), which is equivalent to 188 mg/m3 (referred to herein as the ‘‘2010 NO2 NAAQS’’). Also in 2010 (75 FR 35520, June 22, 2010), EPA established a one-hour SO2 NAAQS of 75 ppb, which is equivalent to 196 mg/m3 (referred to herein as the ‘‘2010 SO2 NAAQS’’). 5 In 2008 (73 FR 16436, March 27, 2008), EPA lowered the 8-hour ozone NAAQS to 0.075 parts per million (ppm) (referred to herein as the ‘‘2008 ozone NAAQS’’). 6 CAA section 110(l) requires SIP revisions to be subject to reasonable notice and public hearing prior to adoption and submittal by States to EPA and prohibits EPA from approving any SIP revision that would interfere with any applicable requirement concerning attainment and reasonable further progress, or any other applicable requirement of the CAA. PO 00000 Frm 00052 Fmt 4700 Sfmt 4700 based on our review of the public participation documentation included in the January 3, 2014 and June 5, 2014 submittals, NDEP has provided sufficient evidence of public notice and opportunity for comment and hearing prior the adoption and submittal to EPA of the rules that are the subject of today’s action. As to the substantive requirements, we start with the amendments to NAC section 445B.308, which include deletion of a paragraph that had not been submitted as part of the Nevada SIP but had established NSR requirements for applicants for permits for certain new sources or modifications proposed to be located in ‘‘basic’’ ozone nonattainment areas. The deletion of NSR requirements for sources or modifications in ‘‘basic’’ ozone nonattainment areas is acceptable because there are no such areas in the State of Nevada, and given court precedent,7 there will not likely be any such areas in Nevada in the future, and thus the provisions that have been deleted from NAC 445B.308 are not necessary to meet CAA requirements. Second, we have considered the amendments to NAC sections 445B.22097 and 445B.311 in relation to 40 CFR 51.160(a), which requires, in connection with NSR, each SIP to set forth legally enforceable procedures that enable the State to determine whether the construction or modification of a stationary source will result in, among other impacts, interference with attainment or maintenance of the NAAQS. EPA regulations also require SIPs to include enforceable procedures under which the State agency responsible for final decision-making on NSR permits will prevent such construction or modification if it will interfere with attainment or maintenance of the NAAQS. See 40 CFR 51.160(b). To address these requirements for minor stationary sources in the Nevada SIP, NAC sections 445B.310 and 445B.311 require permit applicants to prepare environmental evaluations that contain dispersion analyses showing the effect of the source on the quality of the 7 In South Coast Air Quality Management Dist. v. EPA, 472 F.3d 882 (D.C. Cir. 2006) re’g denied 489 F.3d 1245 (clarifying that the vacatur was limited to the issues on which the court granted the petitions for review), the D.C. Circuit Court of Appeals vacated EPA’s classification of certain nonattainment areas for the 1997 8-hour ozone NAAQS solely under subpart 1 of part D of title I of the CAA. In this context, subpart 1 areas refer to ‘‘basic’’ ozone nonattainment areas. Since the South Coast decision, EPA has replaced the subpart 1 (i.e., ‘‘basic’’) ozone classifications for the 1997 ozone NAAQS with subpart 2 classifications (e.g., ‘‘marginal,’’ moderate,’’ or ‘‘serious’’). See 77 FR 28424 (May 14, 2012). E:\FR\FM\21OCR1.SGM 21OCR1 asabaliauskas on DSK5VPTVN1PROD with RULES Federal Register / Vol. 79, No. 203 / Tuesday, October 21, 2014 / Rules and Regulations ambient air, and NAC section 445B.308 prohibits the issuance of a permit or revision for any stationary source if the Environmental Evaluation shows, or NDEP determines, that the stationary source will prevent the attainment and maintenance of the state or national ambient air quality standards, as established in NAC 445B.22097. Permit applicants are required to prepare and submit Environmental Evaluations for any new stationary source which emits, or has the potential to emit, greater than 25 tons per year (tpy) of a regulated air pollutant; and, with respect to modifications, the existing stationary source has the potential to emit greater than 25 tpy of a regulated air pollutant, and the proposed modification has the potential to emit greater than 10 tpy of a regulated air pollutant. See NAC section 445B.310. NAC section 445B.22097 in turn lists the NAAQS and the Nevada ambient air quality standards (‘‘Nevada standards’’). With respect to the NAAQS, in our proposed rulemaking on the previous version of the minor NSR rules, 77 FR 38557, at 38563 (June 28, 2012), we noted that NAC section 445B.22097 had not been updated since 1991 and thus did not include the new, revised, or revoked NAAQS since that time. Moreover, we noted that NAC section 445B.22097 includes a note that states: ‘‘The Director shall use the Nevada standards in considering whether to issue a permit for a stationary source and shall ensure that the stationary source will not cause the Nevada standards to be exceeded in areas where the general public has access.’’ The Nevada standards were equal to the NAAQS (i.e., as of 1991) for those pollutants for which both Nevada and EPA have established ambient standards, but, because the Nevada standards did not reflect the changes in the NAAQS since 1991, reliance on them for permitting purposes did not ensure protection of the new or revised NAAQS established since then, such as the 2006 PM2.5 NAAQS and the 2008 Pb NAAQS, as NDEP reviews permit applications for new or modified minor stationary sources. Thus, in our September 27, 2012 final rule, we concluded that the NSR rules must be revised to ensure protection of the 2006 PM2.5 and the 2008 Pb NAAQS. See 77 FR 59321, at 59325 (September 27, 2012). We also encouraged the Nevada SEC to update NAC section 445B.22097 to take into account the replacement of the 1-hour ozone NAAQS (0.12 ppm) with the 2008 ozone NAAQS, although we did not consider the failure to update the rule for ozone as a significant deficiency because, VerDate Sep<11>2014 16:03 Oct 20, 2014 Jkt 235001 given the regional nature of ambient ozone concentrations, applicants for permits for new or modified minor stationary sources are typically not required to show, through dispersion modeling techniques, that the ozone precursor emissions from the source or modification would not violate the standard. See 77 FR 38557, at 38563 (June 28, 2012). In response, the Nevada SEC updated the NAAQS and Nevada standards in NAC section 445B.22097 through amendments adopted on December 4, 2013 and May 2, 2014, to reflect the 2006 PM2.5 NAAQS, the 2008 ozone NAAQS, and the 2008 Pb NAAQS.8 As such, applicants of new stationary sources with potentials to emit more than 25 tpy of PM2.5, or modifications of such sources with potential to emit more than 10 tpy of PM2.5, must perform dispersion modeling to show the impact of the source or modification on ambient PM2.5 concentrations. In its June 5, 2014 SIP revision submittal, NDEP included a technical support document that provides an explanation of how the 25 tpy modeling threshold (10 tpy for modifications), as opposed to a lower threshold, ensure that new or modified sources do not interfere with attainment or maintenance of the PM2.5 NAAQS. First, after noting that the entire State of Nevada is ‘‘attainment/unclassifiable’’ for the PM2.5 NAAQS, NDEP describes the 25 tpy modeling threshold as protective of the NAAQS in that it has been set at one-quarter of the 100 tpy PSD major source threshold that applies to certain categories of sources (250 tpy is the major source threshold for other sources). In this regard, NDEP also notes that the modeling threshold for modifications (i.e., for sources with potentials to emit greater than 25 tpy) is 10 tpy, the same as EPA’s PSD significant emission rate for PM2.5 (see 40 CFR 51.166(b)(23)), which is presumed to be protective of the NAAQS. Second, NDEP provides a technical evaluation showing how three types of high-emitting stationary combustion sources (deemed ‘‘worstcase’’) would either trigger PSD permitting due to emissions of other criteria pollutants before reaching the 25 tpy PM2.5 modeling threshold or would result (when emitting at 25 tpy) in concentrations that, together with background levels, would be well below 8 On December 14, 2012, the EPA Administrator signed a final rule that lowered the annual PM2.5 NAAQS to 12.0 mg/m3 (referred to herein as the ‘‘2012 PM2.5 NAAQS’’). See 78 FR 3086 (January 15, 2013). Submittals by states of SIP revisions to address the 2012 PM2.5 NAAQS, including revisions related to minor NSR, are not due until 2016. PO 00000 Frm 00053 Fmt 4700 Sfmt 4700 62849 the PM2.5 NAAQS.9 Third, NDEP documents the minor overall contribution of minor stationary sources (about 3% based on the 2011 NEI data) to the PM2.5 emissions inventory for the State of Nevada. We have reviewed the technical support document submitted with the June 5, 2014 SIP revision and agree with NDEP that the 25 tpy modeling threshold for PM2.5 (and 10 tpy for modifications) is protective of the PM2.5 NAAQS. In particular, we find the 25 tpy modeling threshold (10 tpy for modifications) sufficiently protective of the PM2.5 NAAQS given the modeling results presented by NDEP, the low PM2.5 background concentrations, and the ‘‘unclassifiable/attainment’’ designation for the entire State of Nevada for the PM2.5 NAAQS (see 40 CFR 81.329). We conclude that implementation of the 25 tpy modeling threshold (10 tpy for modifications) will provide NDEP with sufficient information to determine whether new minor sources or minor modifications will interfere with attainment or maintenance of the PM2.5 NAAQS and will thus allow NDEP to prevent the construction of such sources or modifications if the modeling analysis indicates that such interference would occur.10 The same holds true with respect to the new or modified sources of Pb and the 2008 Pb NAAQS, but for other reasons. With respect to Pb, the 25 tpy modeling threshold is significantly above the PSD significant emission rate of 0.6 tpy, but, unlike PM2.5, oxides of nitrogen (NOX), and SO2, Pb is not a typical product of combustion given the removal or minimization of Pb in nearly all fuels, with the exception of aviation gasoline used in piston-powered aircraft. Thus, there are few remaining stationary sources of Pb, and of those that remain, such as lead smelters and battery recycling, Pb emissions are likely to exceed 25 tpy and thus would 9 See the industrial boiler combusting residual oil and the reciprocating internal combustion engine (ICE) combusting natural gas scenarios for the first type of result, and the wood-fired boiler scenario for the second type of result, in NDEP’s ‘‘Technical Support Document for Nevada State Implementation Plan Revisions Addressing Minor Source Permitting Program.’’ 10 We also note that Nevada law not only establishes the modeling threshold above which permit applicants of new sources or modifications must perform dispersion modeling but also provides NDEP with the authority to require applicants to submit ‘‘any other information the Director determines is necessary to make an independent air quality impact assessment.’’ NAC 445B.308(1). Such ‘‘other information’’ may include dispersion modeling beyond that otherwise required if necessary to determine whether a new source or modification would interfere with attainment or maintenance of the NAAQS.

Lastly, in our September 27, 2014 final rule, we noted that the deadline for submittal of NSR SIP revisions addressing the 2010 NO2 NAAQS and 2010 SO2 NAAQS had not yet passed, but we encouraged the Nevada SEC to adopt and submit revised NSR rules to address these new NAAQS in a timely manner. To address these new NAAQS, the Nevada SEC adopted revisions to NAC 445B.22097 to update the NAAQS and Nevada standards listed in that rule to reflect the 2010 NO2 and 2010 SO2 NAAQS. Doing so has the effect of requiring applicants for sources or modifications with potentials to emit above certain levels to perform dispersion modeling to inform NDEP’s determination of whether such sources or modifications would interfere with these new NAAQS. For the purposes of dispersion analyses for the 2010 NO2 and 2010 SO2 NAAQS, the Nevada SEC revised NAC 445B.311 to specify modeling thresholds of 40 tpy for both new sources and modifications. The 40 tpy is equivalent to the PSD significant emission rates for NOX and SO2, see 40 CFR 51.166(b)(23). Moreover, NDEP’s technical support document shows that minor stationary sources contribute less than 3% and 6% to the State’s total emissions inventory of NOX and SO2, respectively, and correctly identifies the entire State as ‘‘attainment/ unclassifiable’’ for the 2010 NO2 NAAQS.11 In light of the designations and emissions inventory data, we agree with NDEP that use of the PSD significant emission rate is a reasonable threshold to distinguish sources and modifications that could potentially interfere with attainment or maintenance of the 2010 NO2 or SO2 NAAQS from those with de minimis effects, and will provide NDEP with sufficient information to determine whether new minor sources or minor modifications would interfere with the 2010 NO2 and 2010 SO2 NAAQS. In summary, and for the reasons set forth above, we find that the State of Nevada has adequately addressed the previously-identified deficiencies in the minor source NSR rules and that the amended NSR rules meet the applicable 11 See 40 CFR 81.329. With respect to the 2010 SO2 NAAQS, the EPA designated as nonattainment most areas in locations where existing monitoring data from 2009–2011 indicated violations of the NAAQS. See 78 FR 47191 (August 5, 2013). No such areas were designated within the State of Nevada. EPA has not completed the designation process for the 2010 SO2 NAAQS for areas other than those designated on August 5, 2013.

III. Public Comment and Final Action Pursuant to CAA section 110(k), and for the reasons provided above, EPA is taking direct final action to approve revisions to certain rules that relate to applications for, and issuance of, permits for stationary sources under the jurisdiction of the NDEP, excluding review and permitting of major sources and major modifications under parts C and D of title I of the CAA. Specifically, EPA is approving NAC section 445B.308, as amended on December 4, 2013, and NAC sections 445B.22097 and 445B.311, as amended on May 2, 2014, because we find that the revisions fix the deficiencies in the previouslyapproved versions of the rules and adequately provide for new source review for the new or revised NAAQS for NO2 and SO2.12 We do not think anyone will object to this approval, so we are finalizing it without proposing it in advance. However, in the Proposed Rules section of this Federal Register, we are simultaneously proposing approval of the same submitted revisions. If we receive adverse comments by November 20, 2014, we will publish a timely withdrawal in the Federal Register to notify the public that the direct final approval will not take effect and we will address the comments in a subsequent final action based on the proposal. If we do not receive timely adverse comments, the direct final approval will be effective without further notice on December 22, 2014. This will incorporate the amended rules into the federally enforceable SIP. IV. Statutory and Executive Order Reviews Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve State choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves State rules as meeting Federal requirements and does not impose 12 Upon the effective date of today’s final action, the versions of the rules that we are approving today will supersede NAC section 445B.22097, as approved at 71 FR 15040 (March 27, 2006), and NAC sections 445B.308 and 445B.311, as approved at 77 FR 59321 (September 27, 2012) in the applicable SIP.

For that reason, this action: • Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); • does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and • does not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law. The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and E:\FR\FM\21OCR1.SGM 21OCR1 62851 Federal Register / Vol. 79, No. 203 / Tuesday, October 21, 2014 / Rules and Regulations the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 22, 2014. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the Proposed Rules section of today’s Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements (see section 307(b)(2)).

the Nevada State Implementation Plan; Stationary Source Permits

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is taking direct 
final action to approve revisions to the applicable state 
implementation plan for the State of Nevada submitted by the Nevada 
Division of Environmental Protection. The revisions include amended 
State rules related to applications for, and issuance of, permits for 
stationary sources, but not including review and permitting of major 
sources and major modifications under parts C and D of title I of the 
Clean Air Act. EPA is taking action under the Clean Air Act obligation 
to take action on State submittals of revisions to state implementation 
plans. The intended effect of the approval is to fix deficiencies in 
the previously-approved version of the permitting rules and to ensure 
that new or modified stationary sources do not interfere with 
attainment or maintenance of the national ambient air quality 
standards.

DATES: This rule is effective on December 22, 2014 without further 
notice, unless EPA receives adverse comments by November 20, 2014. If 
we receive such comments, we will publish a timely withdrawal in the 
Federal Register to notify the public that this direct final rule will 
not take effect.

I. The State's Submittals

A. Which rules did the State submit?

    On January 3, 2014, the Nevada Division of Environmental Protection 
(NDEP) submitted a revision to the Nevada State Implementation Plan 
(SIP) to EPA for approval under section 110(k) of the Clean Air Act 
(CAA or ``Act''). NDEP's submittal includes certain amended State rules 
[i.e., certain sections of Nevada Administrative Code (NAC)] that 
relate to applications for, and issuance of, permits for stationary 
sources [a process referred to herein as ``New Source Review'' 
(NSR)].\1\ The specific amended rules submitted on January 3, 2014 are 
NAC sections 445B.22097 (``Standards of quality for ambient air'') and 
445B.308 (``Prerequisites and conditions for issuance of certain 
operating permits; compliance with applicable state implementation 
plan'').\2\ In addition to the amended rules, NDEP's January 3, 2014 
submittal contains evidence of public notice and adoption of the 
amendments to the rules by the Nevada State Environmental Commission 
(SEC) on December 4, 2013, and a copy of the filing by the Legislative 
Counsel Bureau of the amended rules with the Nevada Secretary of State 
on December 23, 2013 making the amendments effective on that date.
---------------------------------------------------------------------------

    \1\ We note that the stationary source permitting rules that are 
the subject of this rule are not related to the requirements for 
pre-construction review and permitting of major sources or major 
modifications under part C (``Prevention of Significant 
Deterioration of air quality'') or part D (``Plan requirements for 
nonattainment areas'') of title I of the Clean Air Act.
    \2\ By letter dated January 28, 2014, NDEP withdrew amended 
versions of NAC sections 445B.308 and 445B.311 that had been 
submitted on January 3, 2014 from EPA consideration as revisions to 
the Nevada SIP, but, by letter dated September 17, 2014, NDEP 
reinstated the January 3, 2014 submittal of NAC 445B.308.
---------------------------------------------------------------------------

    On June 5, 2014, NDEP submitted a second SIP revision including 
further amendments to NAC section 445B.22097 (``Standards of quality 
for ambient air'') and amendments to NAC section 445B.311 
(``Environmental evaluation: Contents; consideration of good 
engineering practice stack height''). We consider the June 5, 2014 
submittal of NAC section 445B.22097 as superseding the submittal of 
that rule on January 3, 2014. NDEP's June 5, 2014 submittal includes a 
technical support document in which NDEP provides its explanation for 
how the amended rules meet CAA requirements. NDEP's June 5, 2014 
submittal also contains evidence of public notice and adoption of the 
amendments to the rules by the Nevada SEC on May 2, 2014. On July 15, 
2014, NDEP provided documentation that the most recent amendments to 
NAC sections 445B.22097 and 445B.311 were filed by the Legislative 
Counsel Bureau with the Nevada Secretary of State on June 23, 2014 and 
are thus in effect as of that date.
    Table 1 below lists the rules that were submitted by NDEP on 
January 3, 2014 and June 5, 2014 and on which EPA is taking action 
today. The three submitted rules represent updated versions of rules 
already approved into the Nevada SIP. We last approved NAC section 
445B.22097 at 71 FR 15040 (March 27, 2006), and last approved NAC 
sections 445B.308 and 445B.311 at 77 FR 59321 (September 27, 2012). 
Upon the effective date of today's final action, the versions of the 
rules that we previously approved will be superseded in the applicable 
SIP by the versions of the rules approved today.

B. What is the regulatory context?

    Under sections 107 and 109 of the CAA, the EPA establishes national 
ambient air quality standards (NAAQS or standards) and designates all 
areas of the country as attainment, nonattainment, or unclassifiable 
for the various NAAQS. To date, EPA has established NAAQS for such 
pervasive pollutants as ozone, carbon monoxide, nitrogen dioxide 
(NO2), sulfur dioxide (SO2), particulate matter, 
and lead (Pb). With respect to particulate matter, EPA has established 
NAAQS for particulate matter with an aerodynamic diameter generally 
less than or equal to 10 microns (PM10) and for particulate 
matter with an aerodynamic diameter generally less than or equal to 2.5 
microns (PM2.5). Under section 110 of the CAA, each state is 
required to develop a state implementation plan (SIP) to implement, 
maintain, and enforce the NAAQS.
    Among the content requirements for SIPs is the requirement to 
develop and submit (for EPA approval) a program to provide for the 
regulation of the modification and construction of any stationary 
source as necessary to assure that the NAAQS are achieved, including a 
permit program as required in parts C and D of title I of the CAA. See 
CAA section 110(a)(2)(C). The permit programs required under parts C 
and D of title I of the CAA are referred to as

[[Page 62848]]

the Prevention of Significant Deterioration (PSD) permit program and 
the Nonattainment New Source Review (NNSR) permit program, 
respectively. Collectively, the PSD and NNSR programs constitute a 
state's ``major source'' permit program, under which applications for 
construction and operation of new major stationary sources and major 
modifications of such sources are reviewed for compliance with the PSD 
and NNSR requirements. New or modified stationary sources that are not 
major sources or major modifications are referred to as minor sources 
(or minor modifications), and the program for review of the 
applications for construction and operation of such sources is referred 
to as the minor source permit program or ``minor NSR.'' Today's action 
relates to three rules promulgated by the Nevada SEC as part of the 
State of Nevada's minor NSR program, which is administered by NDEP. 
NDEP's stationary source jurisdiction extends statewide with respect to 
power plants which generate electricity by using steam produced by the 
burning of fossil fuel, but does not include Clark or Washoe counties 
with respect to all other stationary sources.
    Over the years, the State of Nevada has adopted and implemented, 
and EPA has approved, rules governing minor NSR. Our most recent action 
on Nevada's minor source NSR rules was published on September 27, 2012 
(77 FR 59321). In the September 27, 2012 final rule, we issued a 
limited approval and limited disapproval of a comprehensive update to 
the State's minor source NSR rules. We did so because, although we 
found that the new or amended rules met most of the applicable 
requirements for such NSR programs and that the rules improved the 
existing SIP, we also found certain deficiencies that prevented full 
approval. Specifically, we indicated that the minor NSR rules did not 
address the new or revised NAAQS for PM2.5 and Pb and must 
be revised accordingly.\3\ In addition, we recognized that EPA had 
recently established new or revised NAAQS for NO2 and 
SO2,\4\ and while the State still had additional time to 
amend its NSR rules to address the revised NAAQS for these pollutants, 
we encouraged the Nevada SEC to make any necessary revisions to the 
State's NSR rules to address the revised NAAQS for those two pollutants 
as well, and the NDEP to submit the NSR rules, as revised, to us as a 
SIP revision.
---------------------------------------------------------------------------

    \3\ In 1997 (62 FR 38652, July 18, 1997), EPA first established 
annual and 24-hour PM2.5 NAAQS of 15 micrograms per cubic 
meter ([micro]g/m\3\) and 65 [micro]g/m\3\, respectively. In 2006 
(71 FR 61144, October 17, 2006), EPA lowered the 24-hour 
PM2.5 NAAQS to 35 [micro]g/m\3\. For simplicity, we refer 
herein to the 1997 annual PM2.5 and 2006 24-hour 
PM2.5 NAAQS collectively as the ``2006 PM2.5 
NAAQS.'' In 2008 (73 FR 66964, November 12, 2008), EPA lowered the 
Pb NAAQS to 0.15 [micro]g/m\3\, rolling 3-month average (referred to 
herein as the ``2008 Pb NAAQS'').
    \4\ In 2010 (75 FR 6474, February 9, 2010), EPA established a 
one-hour NO2 NAAQS of 100 parts per billion (ppb), which 
is equivalent to 188 [micro]g/m\3\ (referred to herein as the ``2010 
NO2 NAAQS''). Also in 2010 (75 FR 35520, June 22, 2010), 
EPA established a one-hour SO2 NAAQS of 75 ppb, which is 
equivalent to 196 [micro]g/m\3\ (referred to herein as the ``2010 
SO2 NAAQS'').
---------------------------------------------------------------------------

C. What is the purpose of this direct final rule?

    The Nevada SEC amended NAC section 445B.308 to eliminate an 
outdated provision and to renumber the paragraphs in the rule 
accordingly. The Nevada SEC amended NAC sections 445B.22097 and 
445B.311 to ensure that the new or revised NAAQS for PM2.5, 
Pb, NO2 and SO2 are taken into account in minor 
NSR permitting decisions. The Nevada SEC also updated NAC section 
445B.22097 to reflect the most recent ozone NAAQS.\5\ The purpose of 
this direct final rule is to present our evaluation under the CAA and 
EPA's regulations of the amended NSR rules submitted by NDEP on January 
3, 2014 and June 5, 2014.
---------------------------------------------------------------------------

    \5\ In 2008 (73 FR 16436, March 27, 2008), EPA lowered the 8-
hour ozone NAAQS to 0.075 parts per million (ppm) (referred to 
herein as the ``2008 ozone NAAQS'').
---------------------------------------------------------------------------

II. EPA's Evaluation

A. How is EPA evaluating the rules?

    EPA has reviewed the rules submitted on January 3, 2014 and June 5, 
2014 for compliance with the CAA requirements for SIPs in general set 
forth in CAA section 110(a)(2), for compliance with applicable EPA 
regulations for stationary source permitting programs in 40 CFR part 
51, sections 51.160 through 51.164, and also for compliance with CAA 
requirements for SIP revisions in CAA section 110(l).\6\ As described 
below, EPA has found that the amended rules meet all applicable 
requirements and is thus taking direct final action to approve them as 
revisions to the Nevada SIP.
---------------------------------------------------------------------------

    \6\ CAA section 110(l) requires SIP revisions to be subject to 
reasonable notice and public hearing prior to adoption and submittal 
by States to EPA and prohibits EPA from approving any SIP revision 
that would interfere with any applicable requirement concerning 
attainment and reasonable further progress, or any other applicable 
requirement of the CAA.
---------------------------------------------------------------------------

B. Do the rules meet the evaluation criteria?

    As to procedural requirements for SIPs and SIP revisions, we find 
that, based on our review of the public participation documentation 
included in the January 3, 2014 and June 5, 2014 submittals, NDEP has 
provided sufficient evidence of public notice and opportunity for 
comment and hearing prior the adoption and submittal to EPA of the 
rules that are the subject of today's action.
    As to the substantive requirements, we start with the amendments to 
NAC section 445B.308, which include deletion of a paragraph that had 
not been submitted as part of the Nevada SIP but had established NSR 
requirements for applicants for permits for certain new sources or 
modifications proposed to be located in ``basic'' ozone nonattainment 
areas. The deletion of NSR requirements for sources or modifications in 
``basic'' ozone nonattainment areas is acceptable because there are no 
such areas in the State of Nevada, and given court precedent,\7\ there 
will not likely be any such areas in Nevada in the future, and thus the 
provisions that have been deleted from NAC 445B.308 are not necessary 
to meet CAA requirements.
---------------------------------------------------------------------------

    \7\ In South Coast Air Quality Management Dist. v. EPA, 472 F.3d 
882 (D.C. Cir. 2006) re'g denied 489 F.3d 1245 (clarifying that the 
vacatur was limited to the issues on which the court granted the 
petitions for review), the D.C. Circuit Court of Appeals vacated 
EPA's classification of certain nonattainment areas for the 1997 8-
hour ozone NAAQS solely under subpart 1 of part D of title I of the 
CAA. In this context, subpart 1 areas refer to ``basic'' ozone 
nonattainment areas. Since the South Coast decision, EPA has 
replaced the subpart 1 (i.e., ``basic'') ozone classifications for 
the 1997 ozone NAAQS with subpart 2 classifications (e.g., 
``marginal,'' moderate,'' or ``serious''). See 77 FR 28424 (May 14, 
2012).
---------------------------------------------------------------------------

    Second, we have considered the amendments to NAC sections 
445B.22097 and 445B.311 in relation to 40 CFR 51.160(a), which 
requires, in connection with NSR, each SIP to set forth legally 
enforceable procedures that enable the State to determine whether the 
construction or modification of a stationary source will result in, 
among other impacts, interference with attainment or maintenance of the 
NAAQS. EPA regulations also require SIPs to include enforceable 
procedures under which the State agency responsible for final decision-
making on NSR permits will prevent such construction or modification if 
it will interfere with attainment or maintenance of the NAAQS. See 40 
CFR 51.160(b).
    To address these requirements for minor stationary sources in the 
Nevada SIP, NAC sections 445B.310 and 445B.311 require permit 
applicants to prepare environmental evaluations that contain dispersion 
analyses showing the effect of the source on the quality of the

[[Page 62849]]

ambient air, and NAC section 445B.308 prohibits the issuance of a 
permit or revision for any stationary source if the Environmental 
Evaluation shows, or NDEP determines, that the stationary source will 
prevent the attainment and maintenance of the state or national ambient 
air quality standards, as established in NAC 445B.22097. Permit 
applicants are required to prepare and submit Environmental Evaluations 
for any new stationary source which emits, or has the potential to 
emit, greater than 25 tons per year (tpy) of a regulated air pollutant; 
and, with respect to modifications, the existing stationary source has 
the potential to emit greater than 25 tpy of a regulated air pollutant, 
and the proposed modification has the potential to emit greater than 10 
tpy of a regulated air pollutant. See NAC section 445B.310.
    NAC section 445B.22097 in turn lists the NAAQS and the Nevada 
ambient air quality standards (``Nevada standards''). With respect to 
the NAAQS, in our proposed rulemaking on the previous version of the 
minor NSR rules, 77 FR 38557, at 38563 (June 28, 2012), we noted that 
NAC section 445B.22097 had not been updated since 1991 and thus did not 
include the new, revised, or revoked NAAQS since that time. Moreover, 
we noted that NAC section 445B.22097 includes a note that states: ``The 
Director shall use the Nevada standards in considering whether to issue 
a permit for a stationary source and shall ensure that the stationary 
source will not cause the Nevada standards to be exceeded in areas 
where the general public has access.'' The Nevada standards were equal 
to the NAAQS (i.e., as of 1991) for those pollutants for which both 
Nevada and EPA have established ambient standards, but, because the 
Nevada standards did not reflect the changes in the NAAQS since 1991, 
reliance on them for permitting purposes did not ensure protection of 
the new or revised NAAQS established since then, such as the 2006 
PM2.5 NAAQS and the 2008 Pb NAAQS, as NDEP reviews permit 
applications for new or modified minor stationary sources.
    Thus, in our September 27, 2012 final rule, we concluded that the 
NSR rules must be revised to ensure protection of the 2006 
PM2.5 and the 2008 Pb NAAQS. See 77 FR 59321, at 59325 
(September 27, 2012). We also encouraged the Nevada SEC to update NAC 
section 445B.22097 to take into account the replacement of the 1-hour 
ozone NAAQS (0.12 ppm) with the 2008 ozone NAAQS, although we did not 
consider the failure to update the rule for ozone as a significant 
deficiency because, given the regional nature of ambient ozone 
concentrations, applicants for permits for new or modified minor 
stationary sources are typically not required to show, through 
dispersion modeling techniques, that the ozone precursor emissions from 
the source or modification would not violate the standard. See 77 FR 
38557, at 38563 (June 28, 2012).
    In response, the Nevada SEC updated the NAAQS and Nevada standards 
in NAC section 445B.22097 through amendments adopted on December 4, 
2013 and May 2, 2014, to reflect the 2006 PM2.5 NAAQS, the 
2008 ozone NAAQS, and the 2008 Pb NAAQS.\8\ As such, applicants of new 
stationary sources with potentials to emit more than 25 tpy of 
PM2.5, or modifications of such sources with potential to 
emit more than 10 tpy of PM2.5, must perform dispersion 
modeling to show the impact of the source or modification on ambient 
PM2.5 concentrations.
---------------------------------------------------------------------------

    \8\ On December 14, 2012, the EPA Administrator signed a final 
rule that lowered the annual PM2.5 NAAQS to 12.0 
[micro]g/m\3\ (referred to herein as the ``2012 PM2.5 
NAAQS''). See 78 FR 3086 (January 15, 2013). Submittals by states of 
SIP revisions to address the 2012 PM2.5 NAAQS, including 
revisions related to minor NSR, are not due until 2016.
---------------------------------------------------------------------------

    In its June 5, 2014 SIP revision submittal, NDEP included a 
technical support document that provides an explanation of how the 25 
tpy modeling threshold (10 tpy for modifications), as opposed to a 
lower threshold, ensure that new or modified sources do not interfere 
with attainment or maintenance of the PM2.5 NAAQS. First, 
after noting that the entire State of Nevada is ``attainment/
unclassifiable'' for the PM2.5 NAAQS, NDEP describes the 25 
tpy modeling threshold as protective of the NAAQS in that it has been 
set at one-quarter of the 100 tpy PSD major source threshold that 
applies to certain categories of sources (250 tpy is the major source 
threshold for other sources). In this regard, NDEP also notes that the 
modeling threshold for modifications (i.e., for sources with potentials 
to emit greater than 25 tpy) is 10 tpy, the same as EPA's PSD 
significant emission rate for PM2.5 (see 40 CFR 
51.166(b)(23)), which is presumed to be protective of the NAAQS. 
Second, NDEP provides a technical evaluation showing how three types of 
high-emitting stationary combustion sources (deemed ``worst-case'') 
would either trigger PSD permitting due to emissions of other criteria 
pollutants before reaching the 25 tpy PM2.5 modeling 
threshold or would result (when emitting at 25 tpy) in concentrations 
that, together with background levels, would be well below the 
PM2.5 NAAQS.\9\ Third, NDEP documents the minor overall 
contribution of minor stationary sources (about 3% based on the 2011 
NEI data) to the PM2.5 emissions inventory for the State of 
Nevada.
---------------------------------------------------------------------------

    \9\ See the industrial boiler combusting residual oil and the 
reciprocating internal combustion engine (ICE) combusting natural 
gas scenarios for the first type of result, and the wood-fired 
boiler scenario for the second type of result, in NDEP's ``Technical 
Support Document for Nevada State Implementation Plan Revisions 
Addressing Minor Source Permitting Program.''
---------------------------------------------------------------------------

    We have reviewed the technical support document submitted with the 
June 5, 2014 SIP revision and agree with NDEP that the 25 tpy modeling 
threshold for PM2.5 (and 10 tpy for modifications) is 
protective of the PM2.5 NAAQS. In particular, we find the 25 
tpy modeling threshold (10 tpy for modifications) sufficiently 
protective of the PM2.5 NAAQS given the modeling results 
presented by NDEP, the low PM2.5 background concentrations, 
and the ``unclassifiable/attainment'' designation for the entire State 
of Nevada for the PM2.5 NAAQS (see 40 CFR 81.329). We 
conclude that implementation of the 25 tpy modeling threshold (10 tpy 
for modifications) will provide NDEP with sufficient information to 
determine whether new minor sources or minor modifications will 
interfere with attainment or maintenance of the PM2.5 NAAQS 
and will thus allow NDEP to prevent the construction of such sources or 
modifications if the modeling analysis indicates that such interference 
would occur.\10\
---------------------------------------------------------------------------

    \10\ We also note that Nevada law not only establishes the 
modeling threshold above which permit applicants of new sources or 
modifications must perform dispersion modeling but also provides 
NDEP with the authority to require applicants to submit ``any other 
information the Director determines is necessary to make an 
independent air quality impact assessment.'' NAC 445B.308(1). Such 
``other information'' may include dispersion modeling beyond that 
otherwise required if necessary to determine whether a new source or 
modification would interfere with attainment or maintenance of the 
NAAQS.
---------------------------------------------------------------------------

    The same holds true with respect to the new or modified sources of 
Pb and the 2008 Pb NAAQS, but for other reasons. With respect to Pb, 
the 25 tpy modeling threshold is significantly above the PSD 
significant emission rate of 0.6 tpy, but, unlike PM2.5, 
oxides of nitrogen (NOX), and SO2, Pb is not a 
typical product of combustion given the removal or minimization of Pb 
in nearly all fuels, with the exception of aviation gasoline used in 
piston-powered aircraft. Thus, there are few remaining stationary 
sources of Pb, and of those that remain, such as lead smelters and 
battery recycling, Pb emissions are likely to exceed 25 tpy and thus 
would

[[Page 62850]]

be subject to dispersion modeling to determine whether the source would 
interfere with attainment or maintenance of the 2008 Pb NAAQS.
    Lastly, in our September 27, 2014 final rule, we noted that the 
deadline for submittal of NSR SIP revisions addressing the 2010 
NO2 NAAQS and 2010 SO2 NAAQS had not yet passed, 
but we encouraged the Nevada SEC to adopt and submit revised NSR rules 
to address these new NAAQS in a timely manner. To address these new 
NAAQS, the Nevada SEC adopted revisions to NAC 445B.22097 to update the 
NAAQS and Nevada standards listed in that rule to reflect the 2010 
NO2 and 2010 SO2 NAAQS. Doing so has the effect 
of requiring applicants for sources or modifications with potentials to 
emit above certain levels to perform dispersion modeling to inform 
NDEP's determination of whether such sources or modifications would 
interfere with these new NAAQS. For the purposes of dispersion analyses 
for the 2010 NO2 and 2010 SO2 NAAQS, the Nevada 
SEC revised NAC 445B.311 to specify modeling thresholds of 40 tpy for 
both new sources and modifications. The 40 tpy is equivalent to the PSD 
significant emission rates for NOX and SO2, see 
40 CFR 51.166(b)(23). Moreover, NDEP's technical support document shows 
that minor stationary sources contribute less than 3% and 6% to the 
State's total emissions inventory of NOX and SO2, 
respectively, and correctly identifies the entire State as 
``attainment/unclassifiable'' for the 2010 NO2 NAAQS.\11\ In 
light of the designations and emissions inventory data, we agree with 
NDEP that use of the PSD significant emission rate is a reasonable 
threshold to distinguish sources and modifications that could 
potentially interfere with attainment or maintenance of the 2010 
NO2 or SO2 NAAQS from those with de minimis 
effects, and will provide NDEP with sufficient information to determine 
whether new minor sources or minor modifications would interfere with 
the 2010 NO2 and 2010 SO2 NAAQS.
---------------------------------------------------------------------------

    \11\ See 40 CFR 81.329. With respect to the 2010 SO2 
NAAQS, the EPA designated as nonattainment most areas in locations 
where existing monitoring data from 2009-2011 indicated violations 
of the NAAQS. See 78 FR 47191 (August 5, 2013). No such areas were 
designated within the State of Nevada. EPA has not completed the 
designation process for the 2010 SO2 NAAQS for areas 
other than those designated on August 5, 2013.
---------------------------------------------------------------------------

    In summary, and for the reasons set forth above, we find that the 
State of Nevada has adequately addressed the previously-identified 
deficiencies in the minor source NSR rules and that the amended NSR 
rules meet the applicable requirements for NSR SIPs for all of the new 
or revised NAAQS for PM2.5, Pb, SO2 and 
NO2, other than the 2012 PM2.5 NAAQS for which 
NSR SIP revisions are not yet due.

III. Public Comment and Final Action

    Pursuant to CAA section 110(k), and for the reasons provided above, 
EPA is taking direct final action to approve revisions to certain rules 
that relate to applications for, and issuance of, permits for 
stationary sources under the jurisdiction of the NDEP, excluding review 
and permitting of major sources and major modifications under parts C 
and D of title I of the CAA. Specifically, EPA is approving NAC section 
445B.308, as amended on December 4, 2013, and NAC sections 445B.22097 
and 445B.311, as amended on May 2, 2014, because we find that the 
revisions fix the deficiencies in the previously-approved versions of 
the rules and adequately provide for new source review for the new or 
revised NAAQS for NO2 and SO2.\12\
---------------------------------------------------------------------------

    \12\ Upon the effective date of today's final action, the 
versions of the rules that we are approving today will supersede NAC 
section 445B.22097, as approved at 71 FR 15040 (March 27, 2006), and 
NAC sections 445B.308 and 445B.311, as approved at 77 FR 59321 
(September 27, 2012) in the applicable SIP.
---------------------------------------------------------------------------

    We do not think anyone will object to this approval, so we are 
finalizing it without proposing it in advance. However, in the Proposed 
Rules section of this Federal Register, we are simultaneously proposing 
approval of the same submitted revisions. If we receive adverse 
comments by November 20, 2014, we will publish a timely withdrawal in 
the Federal Register to notify the public that the direct final 
approval will not take effect and we will address the comments in a 
subsequent final action based on the proposal. If we do not receive 
timely adverse comments, the direct final approval will be effective 
without further notice on December 22, 2014. This will incorporate the 
amended rules into the federally enforceable SIP.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve State 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely approves State rules as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by State law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     does not provide EPA with the discretionary authority to 
address disproportionate human health or environmental effects with 
practical, appropriate, and legally permissible methods under Executive 
Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and

[[Page 62851]]

the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. A major rule cannot take effect until 
60 days after it is published in the Federal Register. This action is 
not a ``major rule'' as defined by 5 U.S.C. 804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 22, 2014. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. Parties with objections to this direct final 
rule are encouraged to file a comment in response to the parallel 
notice of proposed rulemaking for this action published in the Proposed 
Rules section of today's Federal Register, rather than file an 
immediate petition for judicial review of this direct final rule, so 
that EPA can withdraw this direct final rule and address the comment in 
the proposed rulemaking. This action may not be challenged later in 
proceedings to enforce its requirements (see section 307(b)(2)).
