Environmental Protection Agency.
Direct final rule.
The Environmental Protection Agency (EPA) is taking direct final action to approve the portions of the state implementation plan (SIP) revisions submitted by the State of South Carolina, through South Carolina Department of Health and Environmental Control (SC DHEC) on August 8, 2014, and August 22, 2014, that address the base year emissions inventory and emissions statements requirements for the State's portion of the bi-state Charlotte-Gastonia-Rock Hill North Carolina-South Carolina 2008 8-hour ozone national ambient air quality standards (NAAQS) nonattainment area (hereinafter referred to as the “bi-state Charlotte Area” or “Area”). Annual emissions reporting (i.e., emissions statements) and a base year emissions inventory are required for all ozone nonattainment areas. The Area is comprised of the entire county of Mecklenburg and portions of Cabarrus, Gaston, Lincoln, Rowan, and Union Counties in North Carolina and a portion of York County in South Carolina. EPA has published proposed and direct final actions on the emissions inventory and emissions statements requirements for the North Carolina portion of the bi-state Charlotte Area in separate rulemaking documents.
This direct final rule is effective August 11, 2015 without further notice, unless EPA receives adverse comment by July 13, 2015. If EPA receives such comments, it will publish a timely withdrawal of the direct final rule in the Federal Register and inform the public that the rule will not take effect.

Start Supplemental Information
On March 12, 2008, EPA promulgated a revised 8-hour ozone NAAQS of 0.075 parts per million (ppm). See 73 FR 16436 (March 27, 2008). Under EPA's regulations at 40 CFR part 50, the 2008 8-hour ozone NAAQS is attained when the 3-year average of the annual fourth-highest daily maximum 8-hour average ambient air quality ozone concentrations is less than or equal to 0.075 ppm. 40 CFR 50.15. Ambient air quality monitoring data for the 3-year period must meet a data completeness requirement. The ambient air quality monitoring data completeness requirement is met when the average percent of days with valid ambient monitoring data is greater than 90 percent, and no single year has less than 75 percent data completeness as determined in Appendix I of part 50.
Upon promulgation of a new or revised NAAQS, the Clean Air Act (CAA or Act) requires EPA to designate as nonattainment any area that is violating the NAAQS based on the three most recent years of ambient air quality data at the conclusion of the designation process. The bi-state Charlotte Area was designated nonattainment for the 2008 8-hour ozone NAAQS on April 30, 2012 (effective July 20, 2012) using 2009-2011 ambient air quality data. See 77 FR 30088 (May 21, 2012). At the time of designation, the bi-state Charlotte Area was classified as a marginal nonattainment area for the 2008 8-hour ozone NAAQS. On March 6, 2015, EPA finalized a rule entitled “Implementation of the 2008 National Ambient Air Quality Standards for Ozone: State Implementation Plan Requirements” (SIP Requirements Rule) that establishes the requirements that state, tribal, and local air quality management agencies must meet as they develop implementation plans for areas where air quality exceeds the 2008 8-hour ozone NAAQS.
See 80 FR 12264. This rule establishes nonattainment area attainment dates based on Table 1 of section 181(a) of the CAA, including an attainment date three years after the July 20, 2012, effective date, for areas classified as marginal for the 2008 8-hour ozone NAAQS. Therefore, the attainment date for the bi-state Charlotte Area is July 20, 2015.
Based on the nonattainment designation, South Carolina was required to develop a SIP revision addressing certain CAA requirements for the Area. Specifically, pursuant to CAA section 182(a)(3)(B) and section 182(a)(1), South Carolina was required to submit a SIP revision addressing the emissions statements and emissions inventory requirements, respectively.
Ground level ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOX) and volatile organic compounds (VOC) in the presence of sunlight. Emissions from industrial facilities and electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents are some of the major sources of NOX and VOC. Section 182(a)(3)(B) of the CAA requires each state with ozone nonattainment areas to submit a SIP revision requiring annual emissions statements to be submitted to the state by the owner or operator of each NOX or VOC stationary source 
located within a nonattainment area showing the actual emissions of NOX and VOC from that source. The first statement is due three years from the area's nonattainment designation, and subsequent statements are due at least annually thereafter. Section 182(a)(1) of the CAA requires states with areas designated nonattainment for the ozone NAAQS to submit a SIP revision providing a comprehensive, accurate, and current inventory of actual emissions from all sources of the relevant pollutant or pollutants in such area. NOX and VOCs are the relevant pollutants because they are the precursors of ozone.
On August 8, 2014, South Carolina submitted a SIP revision that, among Start Printed Page 33415other things, addressed emissions statements requirements related to the 2008 8-hour ozone NAAQS for its portion of the bi-state Charlotte Area. Additionally, on August 22, 2014, South Carolina submitted a SIP revision that included a base year emissions inventory for the Area. EPA is now taking action to approve the portion of the August 8, 2014 SIP revision related to emissions statements as meeting the requirements of sections 110 and 182(a)(3)(B) of the CAA and to approve the portion of the August 22, 2014 SIP revision related to the base year inventory as meeting the requirements of sections 110 and 182(a)(1) of the CAA.
More information on EPA's analysis of South Carolina's SIP revisions provided below.
II. Analysis of State's Submittal
a. Base Year Emission Inventory
As discussed above, section 182(a)(1) of the CAA requires states to submit a comprehensive, accurate, and current inventory of actual emissions from all sources of the relevant pollutant or pollutants in each ozone non-attainment area. The section 182(a)(1) base year inventory is defined in the SIP Requirements Rule as “a comprehensive, accurate, current inventory of actual emissions from sources of VOC and NOX emitted within the boundaries of the nonattainment area as required by CAA section 182(a)(1).” See 40 CFR 51.1100(bb). The inventory year must be selected consistent with the baseline year for the RFP plan as required by 40 CFR 51.1110(b),
and the inventory must include actual ozone season day emissions as defined in 40 CFR 51.1100(cc)
and contain data elements consistent with the detail required by 40 CFR part 51, subpart A. See 40 CFR 51.1115(a), (c), (e). In addition, the point source emissions included in the inventory must be reported according to the point source emissions thresholds of the Air Emissions Reporting Requirements (AERR) in 40 CFR part 51, subpart A. 40 CFR 51.1115(d).
South Carolina selected 2011 as the base year for the emissions inventory which is the year corresponding with the first triennial inventory under 40 CFR part 51, subpart A. This base year is one of the three years of ambient data used to designate the Area as a nonattainment area and therefore represents emissions associated with nonattainment conditions. The emissions inventory is based on data developed and submitted by SC DHEC to EPA's 2011 National Emissions Inventory (NEI), and it contains data elements consistent with the detail required by 40 CFR part 51, subpart A.
South Carolina's emissions inventory for its portion of the Area provides 2011 typical average summer day emissions data for NOX and VOCs for the following general source categories: stationary point, area, non-road mobile, on-road mobile, and events.
A detailed discussion of the inventory development is located in Appendix A of the South Carolina submittal which is provided in the docket for this action. The table below provides a summary of the emissions inventory.
Table 1—2011 Emissions for the South Carolina, York County Portion of the bi-state Charlotte Area
[Tons per summer day]
|County||Point||Area||Non-road mobile||On-road mobile||Events|
|York County *||4.71||4.02||0.93||6.93||2.63||1.78||11.43||5.30||0.04||0.42|
|* Only a portion of York County is located in the nonattainment area.|
The emissions reported for York County reflect the emissions for only the nonattainment portion of the county. The inventory contains point source emissions data for facilities located within the South Carolina portion of the Area based on Geographic Information Systems (GIS) mapping. For the remaining emissions categories, emissions from the South Carolina portion of the bi-state Charlotte Area were determined based on the population of the portion of York County that is included in the Area. More detail on the emissions inventory for individual sources categories is provided below and in Appendix A of the State's August 22, 2014 submittal.
Point sources are large, stationary, identifiable sources of emissions that release pollutants into the atmosphere. The point source emissions inventory for South Carolina's portion of the bi-state Charlotte Area was developed from facility-specific emissions data. A detailed account of the point sources can be found in Appendix A of the August 22, 2014, submittal, which is located in the docket for today's action. The point source emissions data meets the point source emissions thresholds of 40 CFR part 51, subpart A.
Area sources are small emission stationary sources which, due to their large number, collectively have significant emissions (e.g., dry cleaners, service stations). Emissions for these sources were estimated by multiplying an emission factor by such indicators of collective emissions activity as production, number of employees, or population. These emissions were estimated at the county level. South Carolina developed its inventory according to the current EPA emissions Start Printed Page 33416inventory guidance for area sources.
A detailed account of the area sources can be found in Appendix A of the August 22, 2014, submittal.
On-road mobile sources include vehicles used on roads for transportation of passengers or freight. South Carolina developed its on-road emissions inventory using EPA's Motor Vehicle Emissions Simulator (MOVES) model for each ozone nonattainment county.
County level on-road modeling was conducted using county-specific vehicle population and other local data. South Carolina developed its inventory according to the current EPA emissions inventory guidance for on-road mobile sources.
A detailed account of the on-road sources can be found in Appendix A of the August 22, 2014, submittal.
Non-road mobile sources include vehicles, engines, and equipment used for construction, agriculture, recreation, and other purposes that do not use roadways (e.g., lawn mowers, construction equipment, railroad locomotives, and aircraft). South Carolina calculated emissions for most of the non-road mobile sources using EPA's NONROAD2008a model 
and developed its non-road mobile source inventory according to the current EPA emissions inventory guidance for non-road mobile sources.
The railroad locomotive emissions are calculated with fuel use data, track miles and emission factors. A detailed account of the non-road mobile sources can be found in Appendix A of the August 22, 2014, submittal.
SC DEHC included 2011 actual emissions from event sources in its emissions inventory. Events sources in 2011 included wildfires and prescribed fires. Wildfires are unplanned, unwanted wild land fires including unauthorized human-caused fires, escaped prescribed fire projects, or other inadvertent fire situations where the objective is to put the fire out. Prescribed fires are any fires ignited by management actions to meet specific objectives related to the reduction of the biomass potentially available for wildfires. South Carolina calculated actual event source emissions using the 2011 NEI version 1 dataset developed by EPA. A detailed account of the event sources can be found in Appendix A of the August 22, 2014 submittal.
For the reasons discussed above, EPA has determined that South Carolina's emissions inventory meets the requirements under CAA section 182(a)(1) and the SIP Requirements Rule for the 2008 8-hour ozone NAAQS.
b. Emissions Statements
Pursuant to section 182(a)(3)(B), states with ozone nonattainment areas must require annual emissions statements from NOX and VOC stationary sources within those nonattainment areas. This requirement applies to all ozone nonattainment areas regardless of classification (e.g., Marginal, Moderate).
On August 8, 2014, South Carolina submitted a SIP revision to amend portions of Regulation No. 61-62.1, Definitions and General Requirements, as currently incorporated into the SIP, to reflect recent changes to the rule.
The changes to Regulation No. 61-62.1 that address emission statement requirements are the revision to the Section III title,
the addition of a second paragraph to Section III.A.,
and the addition of Section III.C.
EPA has determined that these three specific changes to Section III of Regulation No. 61-62.1, identified in the August 8, 2014 SIP submission, meet the requirements of section 182(a)(3)(B) for the 2008 8-hour ozone NAAQS and is approving those changes into the SIP.
III. Incorporation by Reference
In this rule, EPA is finalizing regulatory text that includes incorporation by reference. In accordance with the requirements of 1 CFR 51.5, EPA is incorporating the following changes to Regulation No. 61-62.1, titled “Definitions and General Requirements”: modification of the title of Section III, addition of a second paragraph to Section III.A defining an “emissions statement,” and addition of Section III.C titled “Emissions Statement Requirements” which were state effective on June 27, 2014. EPA has made, and will continue to make, documents generally available electronically through www.regulations.gov and/or in hard copy at the appropriate EPA office (see the ADDRESSES section of this preamble for more information).
IV. Final Action
EPA is approving the portions of the SIP revisions submitted by South Carolina on August 22, 2014 and August 8, 2014, that relate to the base year emissions inventory and emissions statement requirements,
respectively, for the State's portion of the bi-state Charlotte Area. EPA has concluded that the portions of the State's submissions that EPA is approving meet the relevant requirements of sections 110 and 182 of the CAA. EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse Start Printed Page 33417comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed. This rule will be effective August 11, 2015 without further notice unless the Agency receives adverse comments by July 13, 2015.
If EPA receives such comments, then EPA will publish a document withdrawing the final rule and informing the public that the rule will not take effect. All adverse comments received will then be addressed in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period. Parties interested in commenting should do so at this time. If no such comments are received, the public is advised that this rule will be effective on August 11, 2015 and no further action will be taken on the proposed rule. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, the Agency may adopt as final those provisions of the rule that are not the subject of an adverse comment.
V. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:
- Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
- Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
- Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
- Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
- Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
- Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
- Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
- Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
- Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this direct final rule for the South Carolina portion of the bi-state Charlotte area does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because it does not have substantial direct effects on an Indian Tribe. The Catawba Indian Nation Reservation is located within the South Carolina portion of the bi-state Charlotte Area. Pursuant to the Catawba Indian Claims Settlement Act, S.C. Code Ann. 27-16-120, “all state and local environmental laws and regulations apply to the [Catawba Indian Nation] and Reservation and are fully enforceable by all relevant state and local agencies and authorities.” EPA notes that today's action will not impose substantial direct costs on Tribal governments or preempt Tribal law.
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by August 11, 2015. 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).
