Environmental Protection Agency (EPA).
Direct final rule.
EPA is taking direct final action to approve a revision to the North Carolina State Implementation Plan (SIP), submitted to EPA on February 7, 2011, by the State of North Carolina, through the North Carolina Department of Environment and Natural Resources (NCDENR), Division of Air Quality (DAQ). North Carolina's February 7, 2011, submission supplements the original redesignation request and maintenance plan for the Rocky Mount, North Carolina 1997 8-hour ozone area submitted on June 19, 2006, and approved by EPA on November 6, 2006. The Rocky Mount, North Carolina 1997 8-hour ozone area is comprised of Edgecombe and Nash Counties in North Carolina. North Carolina's February 7, 2011, SIP revision increases the safety margin allocated to motor vehicle emissions budgets (MVEBs) for both Edgecombe and Nash Counties to account for changes in the emissions model and vehicle miles traveled (VMT) projection model. EPA is approving this SIP revision pursuant to section 110 of the Clean Air Act (CAA or Act). North Carolina's February 7, 2011, SIP revision meets all of the statutory and regulatory requirements, and is consistent with EPA's guidance.
This rule is effective on November 26, 2012 without further notice, unless EPA receives relevant adverse comment by October 29, 2012. If EPA receives such comment, EPA will publish a timely withdrawal in the Federal Register informing the public that this rule will not take effect.

II. EPA's Analysis of North Carolina's SIP Revision
III. Final Action
IV. Statutory and Executive Order Reviews
The Rocky Mount, North Carolina 1997 8-hour ozone attainment and maintenance area is comprised of two counties—Edgecombe and Nash (hereafter referred to as the “Rocky Mount Area” or “Area”). In accordance with the CAA, the Rocky Mount Area was designated nonattainment for the 1997 8-hour ozone national ambient air quality standards (NAAQS) on April 30, 2004, with an effective date of June 15, 2004. See 69 FR 23858.
On June 19, 2006, the State of North Carolina, through NCDENR, submitted a final request for EPA to: (1) Redesignate the Rocky Mount Area to attainment; and (2) approve a North Carolina SIP revision containing a maintenance plan for Rocky Mount, North Carolina. On November 6, 2006, EPA approved the redesignation request for the Rocky Mount Area. Additionally, EPA approved the 1997 8-hour ozone maintenance plan (including MVEBs for Edgecombe and Nash Counties) for the Start Printed Page 59336Rocky Mount Area. 71 FR 64891. These approvals were based on EPA's determination that the State of North Carolina had demonstrated that the Rocky Mount Area met the criteria for redesignation to attainment specified in the CAA, including the determination that the entire Rocky Mount Area had attained the 1997 8-hour ozone NAAQS.
In the November 6, 2006, final rulemaking, EPA also found adequate and approved MVEBs for Edgecombe and Nash Counties in the Rocky Mount Area. Specifically, EPA found adequate and approved the 2008 and 2017 MVEBs for nitrogen oxides (NOX) (for both Edgecombe and Nash Counties) that were contained in the 1997 8-hour ozone maintenance plan for the Rocky Mount Area. Further, in the November 6, 2006, action, EPA found adequate and approved the insignificance determination for volatile organic compound (VOC) contribution from motor vehicle emissions to the 1997 8-hour ozone pollution in the Rocky Mount Area.
On February 7, 2011, North Carolina provided a SIP revision (the subject of this action) to increase the amount of safety margins allocated to the NOX MVEBs to account for changes in the projection models. Section II provides EPA's analysis of North Carolina's February 7, 2011, SIP revision.
II. EPA's Analysis of North Carolina's SIP Revision
As discussed above, on February 7, 2011, the State of North Carolina, through NCDENR, submitted a SIP revision to revise the MVEBs for Edgecombe and Nash Counties in the Rocky Mount Area to account for the new emissions model, VMT projection models, and other emission model input data. The MVEBs (expressed in tons per day (tpd) and kilograms per day (kg/d)) that are being updated through today's action were originally approved by EPA on November 6, 2006, and are outlined in the table below.
|Edgecombe County||8.05 tpd||7,302.8 kg/d||6.00 tpd||5,443.1 kg/d.|
|Nash County||13.32 tpd||12,083.7 kg/d||7.41 tpd||6,722.2 kg/d.|
DAQ is currently allocating portions of the available safety margin  to the MVEBs to account for new emissions models, VMT projections models, as well as changes to future vehicle mix assumptions, that influence the emission estimations. DAQ decided to allocate a majority of the safety margin available to the MVEBs. For 2017, DAQ estimated the amount needed to account for the current emission model and VMT projections model, and then added an additional 21 percent to account for any future changes to the emission model, projection model and other input data.
At this time, North Carolina is seeking to adjust the safety margins. The following tables provide the adjusted NOX emissions data, in kg/d for the 2008 base attainment year inventories, as well as the projected NOX emissions inventory 2017.
|Safety Margin Allocated to MVEB||1,674||1,108|
|NOX Conformity MVEB||4,157||2,251|
|Safety Margin Allocated to MVEB||1,655||2,374|
|NOX Conformity MVEB||10,444||6,141|
A total of 3,329 kg (3.67 tons) and 3,482 kg (3.84 tons) of 2008 and 2017 NOx safety margin, respectively, were added to the MVEBs for the Rocky Mount Area. Taking into consideration the portion of the safety margin applied to the MVEBs, the resulting difference between the attainment level of emissions from all sources and the projected level of emissions from all sources in the maintenance area, i.e., the new safety margins, for each projected year is listed.Start Printed Page 59337
|Year||VOC tpd||NOX tpd|
As shown in Tables 2 and 3 above, the Rocky Mount Area is projected to steadily decrease its total VOC and NOX emissions from the base year of 2008 to the maintenance year of 2017. This VOC and NOX emission decrease demonstrates continued attainment/maintenance of the 1997 8-hour ozone NAAQS for ten years from 2008 (the year the Area was effectively designated attainment for the 1997 8-hour ozone NAAQS) as required by the CAA. These projected reductions of ozone precursors indicates continued maintenance of the 1997 8-hour ozone NAAQS.
The revised MVEBs that North Carolina submitted for the Rocky Mount Area were developed with projected mobile source emissions derived using the MOBILE6 motor vehicle emissions model. This model was the most current model available at the time North Carolina was performing its analysis. However, EPA has now issued an updated motor vehicle emissions model known as Motor Vehicle Emission Simulator or MOVES. In its announcement of this model, EPA established a two-year grace period for continued use of MOBILE6.2 in regional emissions analyses for transportation plan and transportation improvement programs (TIPs) conformity determinations (extending to March 2, 2012), after which states (other than California) must use MOVES in conformity determinations for TIPs. As stated above, MOBILE6.2 was the applicable mobile source emissions model that was available when the original SIP was submitted. EPA's “Policy Guidance on the Use of MOVES2010 and Subsequent Minor Revisions for State Implementation Plan Development, Transportation Conformity, and Other Purposes” (http://www.epa.gov/otaq/models/moves/documents/420b12010.pdf) explains that the CAA does not require states that have already submitted SIPs to revise these SIPs simply because a new motor vehicle emissions model is now available. The guidance further states that the use of MOBILE6.2 in an already submitted SIP should not be an obstacle to approval of that SIP assuming that it is otherwise approvable because it would be unreasonable to require revision to a SIP which in this case was submitted prior to the release of MOVES.
III. Final Action
EPA is taking direct final action to approve North Carolina's February 7, 2011, SIP revision to allocate a portion of the available safety margin to the MVEBs for the 1997 8-hour ozone NAAQS for the Rocky Mount, North Carolina Area. The revised MVEBs, for Edgecomb and Nash Counties in North Carolina ensure continued attainment of the 1997 8-hour ozone NAAQS through the maintenance year 2017. EPA has evaluated North Carolina's February 7, 2011, SIP revision, and has determined that it meets the applicable requirements of the CAA and EPA regulations, and is consistent with EPA policy. On March 12, 2008, EPA issued revised ozone NAAQS. The current action, however, is being taken to address requirements under the 1997 8-hour ozone NAAQS.
EPA is publishing this rule without prior proposal because the Agency views this as a non-controversial amendment and anticipates no adverse comments. 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 an adverse comment be filed. This rule will be effective on November 26, 2012 without further notice unless the Agency receives adverse comment by October 29, 2012. 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 public comments received will then be addressed in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. If no such comments are received, the public is advised this rule will be effective on November 26, 2012 and no further action will be taken on the proposed rule.
IV. 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 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 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 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, 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 Start Printed Page 59338of 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 November 26, 2012. 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).Start List of Subjects
