TITLE 326 AIR POLLUTION CONTROL BOARD

The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at 326 IAC 2. The First Notice of Comment Period, published on May 4, 2011 (DIN: 20110504-IR-326110251FNA), requested comments on new source review (NSR) provisions for particulate matter less than 2.5 microns (PM_2.5), as well as amendments to definitions of terms in 326 IAC 2 to defer from greenhouse gas permitting requirements carbon dioxide (CO₂) emissions from bioenergy and other biogenic sources. That comment period has ended; however, IDEM has identified an additional amendment to 326 IAC 2 required by the United States Environmental Protection Agency (U.S. EPA) concerning Indiana's prevention of significant deterioration (PSD) rules. IDEM seeks comment on the additional alternative described in this notice, the affected citation listed, and any other provisions in Title 326 that may be affected by this rulemaking.

A First Notice of Comment Period published in the Indiana Register on May 4, 2011 (DIN: 20110504-IR-326110251FNA) concerning federally required amendments to 326 IAC 2 concerning NSR provisions for PM_2.5 and amendments to the regulatory term "subject to regulation" to defer from greenhouse gas permitting requirements CO₂ emissions from bioenergy and other biogenic sources. This Continuation of First Notice of Comment Period addresses additional alternatives to be considered during this rulemaking.

On November 29, 2005, U.S. EPA published: "Final Rule to Implement the 8-hour Ozone National Ambient Air Quality Standard–Phase 2; Final Rule to Implement Certain Aspects of the 1990 Amendments Relating to New Source Review and Prevention of Significant Deterioration as They Apply in Carbon Monoxide, Particulate Matter and Ozone NAAQS; Final Rule for Reformulated Gasoline" (Phase 2 Implementation Rule) (73 FR 71612). In this rule, U.S. EPA finalized a change to the PSD regulations under Part C of Title I of the Clean Air Act (CAA) by codifying nitrogen oxides (NO_x) as an ozone precursor in attainment and unclassifiable areas. IDEM is proposing to amend 326 IAC 2-2 to make Indiana's PSD rules consistent with U.S. EPA PSD regulations. Amendments may include identifying NO_x as a precursor for ozone in 326 IAC 2.

IDEM is seeking comments on proposed changes to 326 IAC 2 and any other rules that may be affected in Title 326 by this proposed rulemaking. These amendments will make Indiana's air permitting rules consistent with required federal air permitting regulations, on this topic.

The First Notice of Comment Period, published on May 4, 2011 (DIN: 20110504-IR-326110251FNA), included two alternatives for the rulemaking. This Continuation of First Notice of Comment Period adds one additional alternative to be considered.

Alternative 3. Update Indiana's air permitting rules at 326 IAC 2 to make Indiana's PSD air permitting rule consistent with federal PSD air permitting regulations by codifying that NO_x is a precursor for ozone.

40 CFR 50 (National Primary and Secondary Ambient Air Quality Standards) and 40 CFR 51 (Requirements for Preparation, Adoption, and Submittal of Implementation Plans) are applicable federal laws impacting this rulemaking. 40 CFR 50 contains the standards for criteria pollutants. 40 CFR 51 stipulates what states must include in their PSD programs in order to get U.S. EPA approval of their PSD rules.

Potential Fiscal Impact of Alternative 3. This alternative is an incorporation of federal regulations. The CAA requires states to develop a general plan to attain and maintain the national ambient air quality standards. U.S. EPA codified that NO_x is a precursor of ozone in their 2005 Final Rule to Implement the 8-hour Ozone NAAQS. Indiana is required to update the state's PSD air permitting rules to codify that NO_x is a precursor for ozone in Indiana. This amendment is a clarification of rule language to make it consistent with federal regulations and, therefore, IDEM concludes that there is no fiscal impact as a result of this proposed rule amendment.

IDEM established a compliance and technical assistance (CTAP) program under IC 13-28-3.

In accordance with IC 13-28-3 and IC 13-28-5, there is a small business assistance program ombudsman to provide a point of contact for small businesses affected by environmental regulations.
