SUPPLEMENTARY INFORMATION:

I. Overview

EPA is proposing to approve a SIP revision submitted by DAQ, through a letter dated March 21, 2018, seeking to readopt and amend the air quality rules pertaining to transportation conformity in the North Carolina SIP.^[1] North Carolina's SIP submission revises the following North Carolina regulations in 15A NCAC 2D Section .2000: Section .2001 Purpose, Scope and Applicability, Section .2002 Definitions, Section .2003 Transportation Conformity ( printed page 32360) Determination, and Section .2005 Memorandum of Agreement.^[2] The changes to these rules are discussed below in Section II of this proposed rulemaking.

II. Analysis of North Carolina's Submittal

North Carolina's General Statue (G.S.) 150B-21.3A, adopted by the State in 2013, requires state agencies to review existing rules every ten years. The State recently reviewed all air quality rules in 15A NCAC 02D, Air Pollution Control Requirements.^[3] This proposed rulemaking pertains to a SIP revision that North Carolina provided to EPA for approval of changes to “Section .2000— Transportation Conformity. ” ^[4] Section .2000— Transportation Conformity contains the following five rules: Section .2001 Purpose, Scope and Applicability, Section .2002 Definitions, Section .2003 Transportation Conformity Determination, Section .2004 Determining Transportation-Related Emissions,^[5] and Section .2005 Memorandum of Agreement. EPA is proposing action on the following rules: Section .2001 Purpose, Scope and Applicability, Section .2002 Definitions, Section .2003 Transportation Conformity Determination, and Section .2005 Memorandum of Agreement. The changes to these rules are individually described below. If approved, none of these changes would alter the way that transportation conformity requirements are implemented in the State of North Carolina.

Section .2001 Purpose, Scope and Applicability is amended to revise the specific areas to which conformity requirements apply in the following manner: by removing counties and adding certain townships listed in paragraph (b); and by clarifying in paragraph (c) that transportation conformity requirements are applicable to any area that is designated nonattainment or has been previously designated nonattainment and since redesignated to attainment for the PM_2.5 and ozone NAAQS.^[6]

Further, the changes remove provisions related to carbon monoxide areas, which were redesignated to attainment with 10-year maintenance plans effective November 7, 1994,^[7] and September 8, 1995,^[8] and previously demonstrated attainment (containing motor vehicle emissions budgets) through 2015.^[9] As federal transportation conformity requirements no longer apply to the former carbon monoxide nonattainment areas in North Carolina,^[10] the EPA preliminarily concludes that there are no emissions increases associated with this action.

The rule changes also provide that—in addition to stating that transportation conformity requirements apply for 20 years after an area is redesignated to attainment—transportation conformity requirements apply “until the effective date of revocation of the conformity requirements for the NAAQS by EPA.” Additionally, rule .2001 is amended to make non-substantive wording, punctuation and formatting changes.

After evaluation, EPA believes that the changes to North Carolina rule .2001, when taken together, provide the appropriate applicability for transportation conformity requirements, do not materially change the areas to which transportation conformity applies, and are consistent with the CAA requirements for applicable areas. EPA is proposing to approve the changes to rule .2001 because these changes do not alter the applicability for transportation conformity requirements in North Carolina nor do these changes conflict with the federal requirements for transportation conformity.^[11]

Section .2002 Definitions is amended to remove the definition of consultation, and to make non-substantive wording, punctuation and formatting changes (for example, to include hyphens between the words regionally and significant). EPA is proposing to approve the changes to rule .2002 because these changes, including the deletion of the definition of consultation,^[12] do not alter transportation conformity requirements for any applicable area in North Carolina nor do these changes conflict with the federal requirements for transportation conformity.

Section .2003 Transportation Conformity Determination is amended to update references to federal transportation conformity requirements from 40 CFR 93.109 through 93.119 as opposed to referencing the federal transportation conformity requirements from 40 CFR 93.109 through 93.118; ^[13] to clarify that written commitments to implement control measures must be obtained if a control measure is not included in either the transportation plan or the transportation improvement program; and to make non-substantive ( printed page 32361) wording, punctuation and formatting changes. EPA is proposing to approve the changes to rule .2003 because these changes do not alter transportation conformity requirements for any applicable area in North Carolina and these changes are consistent with the federal transportation conformity requirements.

Section .2005 Memorandum of Agreement is amended to provide a more general reference to rule .2001 instead of referencing specific subsections in rule .2001, and to make non-substantive wording, punctuation and formatting changes. EPA is proposing to approve the changes to rule .2005 because these changes do not alter transportation conformity requirements for any applicable area in North Carolina and these changes are consistent with the federal transportation conformity requirements.

In summary, EPA views the amendments described above as consistent with the federal transportation conformity requirements and the Clean Air Act, and is proposing to approve these rules, as amended, into the North Carolina SIP.

III. Incorporation by Reference

In this rule, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with the requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference the following air quality rules in 15A NCAC subchapter 2D.: Section .2001 Purpose, Scope and Applicability, Section .2002 Definitions, Section .2003 Transportation Conformity Determination, and Section .2005 Memorandum of Agreement, state-effective January 1, 2018. EPA has made, and will continue to make, these materials generally available through www.regulations.gov and at the EPA Region 4 office (please contact the person identified in the “For Further Information Contact” section of this preamble for more information).

IV. Proposed Action

For the reasons explained above, EPA is proposing to approve North Carolina's March 21, 2018, SIP revision, which amends and readopts rules 15A NCAC subchapter 2D.: .2001, .2002, .2003, and .2005, for inclusion into North Carolina's SIP.

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. See42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, if they meet the criteria of the CAA. These actions merely propose to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, these proposed actions:

• Are not significant regulatory actions 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);
• Are notExecutive Order 13771 (82 FR 9339, February 2, 2017) regulatory actions because SIP approvals are exempted under Executive Order 12866;
• Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
• Are 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.);
• Do not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 104-4);
• Do not have Federalism implications as specified inExecutive Order 13132 (64 FR 43255, August 10, 1999);
• Are not economically significant regulatory actions based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
• Are not significant regulatory actions subject toExecutive Order 13211 (66 FR 28355, May 22, 2001);
• Are 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
• Do not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, underExecutive Order 12898 (59 FR 7629, February 16, 1994).

The SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.

Authority: 42 U.S.C. 7401 et seq.
