TITLE 326 AIR POLLUTION CONTROL DIVISION

The Indiana Department of Environmental Management (IDEM) is soliciting public comment on the repeal of rules at 326 IAC 8-8 and 326 IAC 8-8.1, and the addition of a new rule at 326 IAC 8-8.2, concerning federal updates to municipal solid waste landfill (MSWLF) rules with the incorporation by reference of 40 CFR 62, Subpart OOO. The purpose of this notice is to seek public comment on the draft rule, including suggestions for specific language to be included in the rule. IDEM seeks comment on the affected citations listed and any other provisions of Title 326 that may be affected by this rulemaking.

IC 13-14-9-7 recognizes that under certain circumstances it may be appropriate to reduce the number of public comment periods routinely provided. In cases where the commissioner determines that the rulemaking policy alternatives available to IDEM are so limited that the first notice of public comment period would provide no substantial benefit to the environment or persons to be regulated or otherwise affected by the proposed rule, IDEM may forgo this comment period and proceed directly to the notice of second public comment period.

If the commissioner makes the determination of limited rulemaking policy alternatives required by IC 13-14-9-7, the commissioner shall prepare written findings and include them in the second notice of public comment period published in the Indiana Register. This document constitutes the commissioner's written findings pursuant to IC 13-14-9-7.

The statute provides for this shortened rulemaking process if the commissioner determines that "the rulemaking policy alternatives available to the department are so limited that the public notice and comment period under [IC 13-14-9-3] . . . would provide no substantial benefit to:

(1) the environment; or

(2) persons to be regulated or otherwise affected by the proposed rule.".

MSWLFs are discrete areas of land or excavation that receive household waste or other types of nonhazardous wastes such as commercial solid waste, nonhazardous sludge, and industrial nonhazardous solid waste. The original New Source Performance Standards (NSPS) (40 CFR 60, Subpart WWW) for MSWLFs and emission guidelines (40 CFR 60, Subpart Cc) for existing MSWLFs were promulgated by the United States Environmental Protection Agency (U.S. EPA) on March 12, 1996 (61 FR 9905), based on the determination that MSWLFs cause or significantly contribute to air pollution that is considered to endanger public health and welfare. Indiana adopted state rules implementing the federal 1996 emission guidelines at 326 IAC 8-8 and 326 IAC 8-8.1 and submitted them to U.S. EPA for state plan approval. U.S. EPA approved Indiana's state plan on March 20, 2000.

U.S. EPA subsequently reviewed the NSPS and emission guidelines in 2014, based on changes in the landfill industry since the rules were first adopted. These changes included changes to the size and number of existing landfills, industry practices, and gas control methods and technologies. This review led to several revisions in August 2016 with the addition of a MSWLF NSPS at 40 CFR 60, Subpart XXX (81 FR 59332), and the emission guidelines for existing MSWLFs at 40 CFR 60, Subpart Cf (81 FR 59276), which implemented changes to existing landfills that lower the emissions threshold at which an operator must install controls. States with existing MSWLFs subject to the new emission guidelines were required to submit state plans implementing the 2016 MSWLF emission guidelines by May 30, 2017. The NSPS requirements at 40 CFR 60, Subpart XXX are self-implementing and are not addressed in the federal requirements for state plans.

The May 30, 2017, deadline was subsequently extended to August 26, 2019, in a final rule that promulgated revised MSWLF state and federal plan timing requirements in a new Subpart Ba (84 FR 44547). However, this extension was challenged by the American Lung Association and subsequently vacated in the United States Court of Appeals for the D.C. Circuit, and the original date was restored. States that did not submit an approvable plan by the May 30, 2017, deadline would become subject to federal plan requirements. On February 29, 2020, U.S. EPA found that 42 states failed to submit state plans for the new federal requirements, and a final rule at 40 CFR 62, Subpart OOO was published on May 21, 2021, that established federal plan requirements for states that failed to submit a plan by the deadline (86 FR 27756). Indiana is one of the 42 states that did not submit a new state plan to U.S. EPA. On March 26, 2020, U.S. EPA also amended the emission guidelines at 40 CFR 60, Subpart Cf, to address administrative amendments and establish requirements consistent with the National Emission Standard for Hazardous Air Pollutants (NESHAP) that also applies to MSWLFs.

Consequently, MSWLFs in Indiana are subject to the federal plan at 40 CFR 62, Subpart OOO, and the state rules implementing the 1996 emission guidelines at 326 IAC 8-8 or 326 IAC 8-8.1. While it is U.S. EPA's intention that the 2021 federal plan replaces the existing 2016 approved state plan, the federal rules for the 2016 emission guidelines did not repeal 40 CFR 60, Subpart WWW that Indiana's state rules rely on, thus creating conflicting requirements for Indiana sources. IDEM intends to address this conflict with a Nonrule Policy Document in the interim, until this rulemaking is final and effective.

This rulemaking will repeal 326 IAC 8-8 and 326 IAC 8-8.1, and add a new rule at 326 IAC 8-8.2, to incorporate 40 CFR 62, Subpart OOO for MSWLFs into state rules, which will remove the conflicting requirements. The incorporation by reference also includes the updated federal language added on February 14, 2022 (87 FR 8203), to several sections of 40 CFR 62 to clarify compliance schedules, the closed subcategory, and the definition of "administrator". Once this rule is final, IDEM will submit a state plan to U.S. EPA for approval. Once approved by U.S. EPA, the federal plan will no longer be in effect in Indiana, which will remove the conflicting federal and state requirements.

It should also be noted that while 326 IAC 8-8.1 was put in place solely to address the requirements for a state plan under 40 CFR 60, Subpart Cc, the additional rule at 326 IAC 8-8 for landfills located in Lake, Porter, Clark, and Floyd counties was implemented to address volatile organic compound emission reductions for ozone nonattainment counties. The emission standards in the new rule at 326 IAC 8-8.2 will be applicable statewide and will be sufficient for Indiana to continue meeting ozone planning requirements. Indiana also intends to request a state implementation plan revision to replace 326 IAC 8-8 with the new rule at 326 IAC 8-8.2 once this rulemaking is final.

IDEM seeks comment on the affected citations listed, including suggestions for specific language, any other provisions of Title 326 that may be affected by this rulemaking, and alternative ways to achieve the purpose of the rulemaking.

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 rulemaking has no impact beyond that which is already imposed by federal law.

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).
