Start Preamble


Environmental Protection Agency (EPA).


Final rule.


Under the Federal Clean Air Act (CAA), the Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) submissions from the State of Oklahoma regarding the 2008 Lead (Pb), 2008 Ozone, 2010 Nitrogen Dioxide (NO2), and 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS or standards). The four submittals address how the existing SIP provides for implementation, maintenance, and enforcement of these four NAAQS (infrastructure SIP or i-SIP). These i-SIPs ensure that the Oklahoma SIP is adequate to meet the State's responsibilities under the CAA, including the CAA requirements for interstate transport of Pb and NO2 emissions.


This rule is effective on January 9, 2017.

I. Background

The background for this action is discussed in detail in our September 20, 2016, proposal (81 FR 64377). In that document we proposed to approve the Oklahoma i-SIP submittals dated October 5, 2012; February 28, 2014; and January 28, 2015, which addressed the 2008 Pb NAAQS; the 2010 NO2 NAAQS; and the 2008 ozone and 2010 SO2 NAAQS as meeting the requirements of an i-SIP. Two of the submittals did not address Section 110(a)(2)(D)(i)(I), prongs 1 and 2, regarding the contribution to nonattainment and interfere with maintenance of the 2008 ozone and 2010 SO2 NAAQS in other states, so we did not propose to take action on such elements for these two NAAQS. In addition, we did not propose to take action on section 110(a)(2)(D)(i)(II)—the prong that specifically addresses visibility protection for the 2010 SO2 NAAQS. We will take separate action on these three prongs for the 2008 ozone and 2010 SO2 NAAQS. We did not receive any comments regarding our proposal.

II. Final Action

EPA is approving in part the October 5, 2012, February 28, 2014, and January 28, 2015, infrastructure SIP submissions from Oklahoma, which address the requirements of CAA sections 110(a)(1) and (2) as applicable to the 2008 Pb, 2010 NO2, 2008 ozone, and 2010 SO2 NAAQS. Table 1 outlines the specific actions we are approving.

Key to Table 1:

A—Approving in this action.
SA—Acting on this infrastructure requirement in a separate rulemaking.

Based upon review of these infrastructure SIP submissions and relevant statutory and regulatory authorities and provisions referenced in these submissions and referenced in the Oklahoma SIP, we find Oklahoma has the infrastructure in place to address all applicable required elements of sections 110(a)(1) and (2), except as noted in Table 1, to ensure that the 2008 Pb, 2008 Ozone, 2010 NO2, and 2010 SO2 NAAQS are implemented in the State. This action is being taken pursuant to section 110 of the Act.

III. 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, the 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, 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 and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

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 February 7, 2017. 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. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
