AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a September 7, 2017, request by the Indiana Department of Environmental Management (IDEM) to revise the Indiana state implementation plan (SIP) for ozone. IDEM revised its ozone standard in order to be consistent with EPA's 2015 revisions to the 8-hour national ambient air quality standards (NAAQS). IDEM also revised the references to the monitoring test methods in its rules to the current EPA test methods. EPA is also proposing to approve administrative revisions to regulations addressing other ambient air quality standards.

DATES:

Comments must be received on or before June 1, 2018.

I. Background

On October 26, 2015 (80 FR 65291), EPA revised the primary and secondary ozone NAAQS from 0.075 to 0.070 parts per million (ppm), daily maximum 8-hour concentration, codified at 40 CFR 50.19. The ozone NAAQS continues to use an 8-hour averaging time, calculated as the fourth-highest daily maximum averaged across three consecutive years. IDEM revised its ambient air quality primary and secondary standards for ozone to be consistent with EPA's 2015 revision, and codified that revision at 326 Indiana Administrative Code (IAC) 1-3-4, Ambient Air Quality Standards.

On October 26, 2015 (80 FR 65291), EPA also revised the monitoring test methods for ozone, which are codified at 40 CFR part 50 appendices D and U, and at 40 CFR part 53. IDEM revised 326 IAC 1-3-4(4)(B) to update its references to those Federal monitoring test methods.

Indiana also made administrative revisions throughout 326 IAC 1-3-4 for ambient air quality standards other than ozone. This includes changing “shall represent” to “represents” and “shall” to “must.”

IDEM posted notice by March 3, 2017, for the Environmental Rules Board meeting on April 12, 2017, at which public comment was taken on the ambient air quality standard revisions. There were no public comments. On September 7, 2017, IDEM requested approval of 326 IAC 1-3-4 into the Indiana SIP.

II. What is EPA's analysis?

IDEM's revisions to 326 IAC 1-3-4(4) make its ambient air quality standards consistent with the federal 2015 8-hour ozone NAAQS. Aligning the ambient air quality standards ensures consistency between EPA's and IDEM's ozone standards. IDEM's updates to the monitoring test methods for ozone keep the state's test methods consistent with the federal test methods. EPA also finds that the administrative revisions made in 326 IAC 1-3-4 are minor and do not alter the state's ambient air quality standards, which remain consistent with the NAAQS.

III. What action is EPA taking?

EPA is proposing to approve revisions to Indiana's ambient air quality standards in 326 IAC 1-3-4 into the Indiana SIP. The revisions to 326 IAC 1-3-4 include aligning both IDEM's ozone standard with the 2015 8-hour ozone NAAQS as codified at 40 CFR part 50 and the monitoring test methods for ozone as codified at 40 CFR part 50 and 40 CFR part 53. Further, administrative revisions were made to IDEM's other ambient air quality standards in 326 IAC 1-3-4. This SIP revision request was submitted on September 7, 2017.

IV. 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 requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference 326 IAC 1-3-4, effective August 11, 2017. EPA has made, and will continue to make, these documents generally available through www.regulations.gov, and at the EPA Region 5 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information).

V. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Clean Air 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 Clean Air Act. 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);
  • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866;
  • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);Start Printed Page 19195
  • 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 Clean Air Act; 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).
