Start Preamble


Environmental Protection Agency (EPA).


Direct final rule.


The Environmental Protection Agency (EPA) is taking direct final action to approve elements of a State Implementation Plan (SIP) submission, and an amended SIP submission from the State of Iowa for the 2010 Nitrogen Dioxide (NO2) National Ambient Air Quality Standard (NAAQS).

Infrastructure SIPs address the applicable requirements of Clean Air Act (CAA) section 110, which requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by the EPA. These SIPs are commonly referred to as “infrastructure” SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA.


This direct final rule will be effective November 20, 2017, without further notice, unless EPA receives adverse comment by October 20, 2017. If EPA receives adverse comment, we will publish a timely withdrawal of the direct final rule in the Federal Register informing the public that the rule will not take effect.


Submit your comments, identified by Docket ID No. EPA-R07-OAR-2017-0208, to Follow the online instructions for submitting comments. Once submitted, comments cannot be edited or removed from EPA may publish any comment received to its public docket. Do not submit electronically any information you consider to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Multimedia submissions (audio, video, etc.) must be accompanied by a written comment. The written comment is considered the official comment and should include discussion of all points you wish to make. The EPA will generally not consider comments or comment contents located outside of the primary submission (i.e. on the web, cloud, or other file sharing system). For additional submission methods, the full EPA public comment policy, information about CBI or multimedia submissions, and general guidance on making effective comments, please visit​dockets/​commenting-epa-dockets.

Throughout this document “we,” “us,” and “our” refer to EPA. This section provides additional information by addressing the following:

I. What is being addressed in this document?

II. Have the requirements for approval of a SIP revision been met?

III. What action is EPA taking?

IV. Statutory and Executive Order Reviews

I. What is being addressed in this document?

EPA is approving elements of the 2010 NO2 NAAQS infrastructure SIP submission from the State of Iowa received on July 29, 2013, and an amended SIP submission received on March 9, 2017. Specifically, EPA is approving the following elements of section 110(a)(2): (A), (B), (C), (D)(i)(I)—significant contribution to nonattainment (prong 1), interfering with maintenance of the NAAQS (prong 2) and (D)(i)(II)—prevent of significant deterioration of air quality (prong 3), and (D)(ii), (E) through (H), and (J) through (M). EPA is not acting on the elements of section 110(a)(2)(D)(i)(II)—protection of visibility (prong 4), and 110(a)(2)(I).

A Technical Support Document (TSD) is included as part of this docket to discuss the details of this action, including analysis of how the SIP meets the applicable 110 requirements for infrastructure SIPs.

II. Have the requirements for approval of a SIP revision been met?

The state submission has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The state initiated public comment from April 6, 2013, to May 8, 2013. One comment was received and adequately addressed in the final SIP submission. The amended submission was placed on public comment January 12, 2017, to February 15, 2017. No comments were received. These submissions also satisfied the completeness criteria of 40 CFR part 51, appendix V. In addition, as explained above and in more detail in the technical support document which is part of this docket, the revisions meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations.

III. What action is EPA taking?

EPA is approving elements of the July 23, 2013, (received July 29, 2013) infrastructure SIP submission from the State of Iowa, which addresses the requirements of CAA sections 110(a)(1) and (2) as applicable to the 2010 NO2 NAAQS. As stated above, EPA is approving the following elements of section 110(a)(2): (A), (B), (C), (D)(i)(I)—significant contribution to nonattainment (prong 1), interfering with maintenance of the NAAQS (prong 2) and (D)(i)(II)—prevent significant deterioration of air quality (prong 3), and (D)(ii), (E) through (H), and (J) through (M). The March 1, 2017, SIP amendment, revised 110(a)(2)(D)(i)(I). Details of the submission are addressed in the TSD, included as part of the docket, to discuss this approval action.

EPA is not taking action on section 110(a)(2)(I). Section 110(a)(2)(I) requires that in the case of a plan or plan revision for areas designated as nonattainment areas, states must meet applicable requirements of part D of the CAA, relating to SIP requirements for designated nonattainment areas. EPA does not expect infrastructure SIP submissions to address element (I). The specific SIP submissions for designated nonattainment areas, as required under CAA title I, part D, are subject to different submission schedules than those for section 110 infrastructure elements. EPA will take action on part D attainment plan SIP submissions through a separate rulemaking governed by the requirements for nonattainment areas, as described in part D.

EPA is not taking action on section 110(a)(2)(D)(i)(II), prong 4.

We are publishing this direct final rule without a prior proposed rule because we view this as a noncontroversial action and anticipate no adverse comment. However, in the “Proposed Rules” section of this Federal Register, we are publishing a separate document that will serve as the proposed rule to approve the SIP Start Printed Page 43847revision if adverse comments are received on this direct final rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information about commenting on this rule, see the ADDRESSES section of this document. If EPA receives adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that this direct final rule will not take effect. We will address all public comments in any subsequent final rule based 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 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).

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 November 20, 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).)
