TITLE 326 AIR POLLUTION CONTROL DIVISION

The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at 326 IAC 7 concerning sulfur dioxide (SO₂) emission limitations. The First Notice of Comment Period, published on June 29, 2011 (DIN: 20110629-IR-326110356FNA), requested comments on sulfur dioxide emission limitations to support the new 2010 1-hour SO₂ National Ambient Air Quality Standard (NAAQS). That comment period has ended. However, IDEM has since limited the scope of this rulemaking. IDEM seeks comment on the affected citations listed and any other provisions of Title 326 that may be affected by this rulemaking.

First Notice of Comment Period: June 29, 2011, Indiana Register (DIN: 20110629-IR-326110356FNA).

A First Notice of Comment Period was published in the Indiana Register on June 29, 2011 (DIN: 20110629-IR-326110356FNA), concerning sulfur dioxide emission limitations and ambient monitoring to support the new 2010 1-hour SO₂ NAAQS. This Continuation of First Notice of Comment Period addresses additional information that has become available since the notice was published.

The United States Environmental Protection Agency (U.S. EPA) issued a revised primary NAAQS for SO₂ in the June 22, 2010, Federal Register published at 75 FR 35520. The largest sources of SO₂ emissions are from fossil fuel combustion at power plants and other industrial facilities. Smaller sources of SO₂ emissions include industrial processes, such as extracting metal from ore, and the burning of high sulfur fuels by locomotives, large ships, and nonroad equipment.

Final designations for nonattainment based on monitoring data through 2012 were made on August 5, 2013 (78 FR 47191). Townships designated as nonattainment in Indiana are as follows:

Marion County (Wayne, Center, Perry)

Morgan County (Clay, Washington)

Daviess County (Veale)

Pike County (Washington)

Vigo County (Fayette, Harrison)

U.S. EPA will determine designations for additional areas based on additional monitoring or modeling, or both, at a later date. However, areas that may be designated as nonattainment or unclassifiable based on modeling are no longer the subject of this rulemaking. In addition, IDEM is no longer proposing to revise the SO₂ ambient monitoring requirements at 326 IAC 7-3 in this rulemaking. U.S. EPA may establish alternative monitoring requirements for areas not addressed within the August 5, 2013, designations.

This rulemaking will revise or add emission limitations in 326 IAC 7 to address state implementation plan (SIP) development requirements for counties with townships designated as nonattainment for the 1-hour standard on August 5, 2013. Federal law does not detail the exact emission controls needed to address nonattainment counties, but emission limitations must demonstrate compliance with the 1-hour SO₂ NAAQS. IDEM will also amend the current emission limitations in 326 IAC 7 to address the numerous sources that are now closed.

Alternative 1. Amend 326 IAC 7 and any other provision of Title 326 that may be affected by this rulemaking to address SIP requirements for nonattainment areas designated on August 5, 2013. Amend 326 IAC 7 to delete closed sources.

Alternative 2. Amend the rule as proposed in the First Notice of Comment Period on June 29, 2011, by amending/adding emission limitations and monitoring requirements at 326 IAC 7. This is not the preferred approach as IDEM is proposing to narrow the scope of this rulemaking. At this time, U.S. EPA has only made designations for the counties/townships listed above.

Alternative 3. Do not amend 326 IAC 7.

The revised primary NAAQS for SO₂ published in the June 22, 2010, Federal Register (75 FR 35520) and the nonattainment designations published in the August 5, 2013, Federal Register (78 FR 47191).

Potential Fiscal Impact of Alternative 1. At this time, IDEM does not know the fiscal impact of developing emission limitations to address the 1-hour SO₂ NAAQS for the areas designated nonattainment on August 5, 2013. As emission limitations are developed, IDEM will evaluate the fiscal impact of the proposed requirements. Affected sources may need to install additional air pollution control devices to meet the requirements proposed.

Potential Fiscal Impact of Alternative 2. The fiscal impact of the proposed rulemaking in the First Notice of Comment Period on June 29, 2011, would affect more sources than proposed in this notice and would have a greater fiscal impact than Alternative 1. However, it is not possible to quantify those impacts at this time.

Potential Fiscal Impact of Alternative 3. There is no fiscal impact associated with this alternative. IDEM is required by federal law to address the revised 1-hour SO₂ NAAQS. If the state does not impose requirements on affected sources, U.S. EPA will impose requirements, and there will still be a fiscal impact.

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