STATUTORY REQUIREMENTS
IC 13-14-9-8 recognizes that, under certain circumstances, it may be appropriate to reduce the number of public comment periods and public hearings usually provided for under the IC 13-14-9 environmental rulemaking process. In cases where the commissioner determines that there is no reasonably anticipated benefit from a second public comment period and first public hearing to either the environment or persons regulated or otherwise affected by the draft rule, IDEM may forgo these comment periods and proceed directly to the public hearing and board meeting at which the draft rule is considered for adoption. Two opportunities for public comment (with this notice and at the public hearing prior to adoption of the rule) remain under this procedure.
If the commissioner makes the determination of no anticipated benefit required by IC 13-14-9-8, the commissioner shall prepare written findings and publish those findings in the Indiana Register prior to the board meeting at which the draft rule is to be considered for adoption and include them in the board packet prepared for that meeting. This document constitutes the commissioner's written findings pursuant to IC 13-14-9-8.
The statute provides for this shortened rulemaking process if the commissioner determines that:
(1) the rule constitutes:
(A) an adoption or incorporation by reference of a federal law, regulation, or rule that:
(i) is or will be applicable to Indiana; and
(ii) contains no amendments that have a substantive effect on the scope or intended application of the federal law or rule;
(B) a technical amendment with no substantive effect on an existing Indiana rule; or
(C) an amendment to an existing Indiana rule, the primary and intended purpose of which is to clarify the existing rule; and
(2) the rule is of such nature and scope that there is no reasonably anticipated benefit to the environment or the persons referred to in IC 13-14-9-7(a)(2) from:
(A) exposing the rule to diverse public comment under IC 13-14-9-3 or IC 13-14-9-4;
(B) affording interested or affected parties the opportunity to be heard under IC 13-14-9-3 or IC 13-14-9-4; and
(C) affording interested or affected parties the opportunity to develop evidence in the record collected under IC 13-14-9-3 and IC 13-14-9-4.

BACKGROUND
The Clean Air Act (CAA) requires that the United States Environmental Protection Agency (U.S. EPA) set NAAQS for pollutants that cause or contribute to air pollution which may reasonably be anticipated to endanger public health and welfare. U.S. EPA has set NAAQS for six criteria pollutants, which are carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), and sulfur dioxide (SO2). Each county in Indiana is designated as being in attainment if air quality monitoring or modeling indicate that the area is meeting the NAAQS. Areas are designated as nonattainment if the measured concentrations of one or more of these criteria pollutants exceed the NAAQS or contribute significant amounts of pollutants to an area that measures air quality that does not meet the NAAQS. An area can be redesignated from nonattainment to attainment if the area has demonstrated attainment of the standard, and if U.S. EPA has determined that the improvement in air quality is due to permanent and enforceable reductions in emissions.
Indiana's attainment status tables at 326 IAC 1-4 are periodically updated to reflect each county's attainment status. This rulemaking updates the attainment designation status for ninety of Indiana's ninety-two counties for SO2 to accurately reflect the federal language used in the Code of Federal Regulations (CFR) at 40 CFR 81.315. This rulemaking also updates the designation status of Porter County under the 2015 8-hour ozone NAAQS based on the final rule published by U.S. EPA in the Federal Register (FR) on June 14, 2021 (86 FR 31438). In order to avoid conflict with ongoing litigation concerning a challenge to the designation status for several townships in Huntington County, the rule language differs from what is currently reflected in 40 CFR 81.315 and will be updated, if necessary, once the challenge is resolved.
Daviess and Pike counties have been omitted from this rulemaking and are included in a separate rulemaking that amends the attainment designation status for the 2010 1-hour primary NAAQS for SO2 for two townships that were redesignated from nonattainment to attainment by U.S. EPA in a final rule published on March 2, 2021 (86 FR 12107). To ensure the timely update of the attainment status for these two counties, the separate rule was initiated before this rulemaking updating the SO2 redesignation status for the ninety remaining counties in Indiana. Therefore, the updates for both the primary 1-hour SO2 standard and the 1971 secondary 3-hour SO2 standard for Daviess and Pike counties are contained in the separate rulemaking to avoid confusion and any potential crossover errors between the two rules.
IC 13-14-9-4 Identification of Restrictions and Requirements Not Imposed under Federal Law
No element of the draft rule imposes either a restriction or a requirement on persons to whom the draft rule applies that is not imposed under federal law. This draft rule imposes no restrictions or requirements because it is a direct adoption of federal requirements that are applicable to Indiana and contains no amendments that have a substantive effect on the scope or application of the federal rule.
Potential Fiscal Impact
This rulemaking makes amendments to rules at 326 IAC 1-4 to update the attainment designation status for ninety Indiana counties under the primary and secondary NAAQS for SO2, as well as updates to 326 IAC 1-4-65 to change the designation status of Porter County under the 2015 8-hour O3 standard. Because this rule is a technical amendment that updates the attainment designation status for counties in Indiana to ensure that state rules are consistent with federal standards, no impact beyond that already imposed by the federal law is imposed by this rulemaking.
Public Participation and Work Group Information
At this time, no work group is planned for the rulemaking. If you feel that a work group or other informal discussion on the rule is appropriate, please contact Keelyn Walsh, Rules Development Branch, Office of Legal Counsel at kwalsh@idem.in.gov, (317) 232-8229 or (800) 451-6027 (in Indiana).

FINDINGS
The commissioner of IDEM has prepared findings regarding rulemaking on amendments to rules at 326 IAC 1-4 concerning updates to the attainment designation status for ninety Indiana counties under the primary and secondary NAAQS for SO2, as well as updates to 326 IAC 1-4-65 to change the designation status of Porter County under the 2015 8-hour O3 standards required by federal law. These findings are prepared under IC 13-14-9-8 and are as follows:
(1) This rule is a technical amendment with no substantive effect on an existing Indiana rule.
(2) Indiana is required to adopt the updates to the attainment designation statuses for ninety of Indiana's ninety-two counties for SO2 to accurately reflect the federal language used in the Code of Federal Regulations (CFR) at 40 CFR 81.315, as well as an update to the designation status of Porter County under the 2015 8-hour ozone NAAQS based on the final rule published by U.S. EPA in the Federal Register (FR) on June 14, 2021 (86 FR 31438).
(3) The environment and persons regulated or otherwise affected by the draft rule will benefit from prompt adoption of this rule, because it will update the attainment designation statuses for ninety of Indiana's ninety-two counties for SO2, as well as the designation status of Porter County under the 2015 8-hour ozone NAAQS. This rule will ensure that state rules are consistent with federal regulations.
(4) I have determined that, under the specific circumstances pertaining to this rule, there would be no reasonably anticipated benefit to the environment or to persons regulated or otherwise affected by the draft rule from the first or second written comment period under IC 13-14-9-3 or IC 13-14-9-4, or from the first public hearing under IC 13-14-9-5(a)(1).
(5) The draft rule is hereby incorporated into these findings.
