TITLE 326 AIR POLLUTION CONTROL DIVISION

SECOND NOTICE OF COMMENT PERIOD
LSA Document #16-309

SHORT TERM BACKUP UNITS


PURPOSE OF NOTICE
The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at 326 IAC 2-1.1-3 concerning the operation of short term backup units. IDEM seeks comment on the affected citations listed and any other provisions of Title 326 that may be affected by this rulemaking.

HISTORY
First Notice of Comment Period: July 20, 2016, Indiana Register (DIN: 20160720-IR-326160309FNA).
Continuation of First Notice of Comment Period: May 9, 2018, Indiana Register (DIN: 20180509-IR-326160309FCA).

CITATIONS AFFECTED: 326 IAC 2-1.1-3.


SUBJECT MATTER AND BASIC PURPOSE OF RULEMAKING
Basic Purpose and Background
The provisions of 326 IAC 2-1.1-3 identify specific conditions under which emission units, operations, or processes are exempt from construction or modification requirements in Indiana's air permitting rules. When an existing permitted emission unit or its control device at a source needs to be taken offline for the purpose of repairing or performing maintenance, a different emission unit or control device often needs to be inserted into the process in its place in order for the process to continue operating while the repair or maintenance is completed. The repairs to these permitted emission units often last longer than thirty (30) days. The current rules do not allow an exemption for this scenario, even though the short term backup unit is often nearly identical to the permitted emission unit taken offline for repair, and there would be no increase in emissions or decrease in control levels. A source that needs to obtain a short term backup unit for this purpose currently must submit a request for a modification of its registration or permit and get approval prior to bringing the short term backup unit on site or operating it. For the source, this can result in additional downtime, lost productivity, extra costs, and the risk of being in violation of the rule if a short term backup unit is used to continue operations.
IDEM requested public comment from July 20, 2016, through August 19, 2016, on alternative ways to achieve the purpose of the rule. In the First Notice, a section pertaining to the applicable federal law to the rulemaking was inadvertently omitted; therefore, IDEM provided for an additional 30-day comment period on the rulemaking from May 9, 2018, through June 8, 2018.
IDEM is proposing changes to 326 IAC 2-1.1-3 to add a provision to the list of exemptions, at 326 IAC 2-1.1-3(h), to allow the operation of a short term backup unit under certain circumstances without first seeking a modification to a permit. A short term backup unit could be used as a part of normal operations while repairs or maintenance are completed to the original equipment in a reasonable amount of time, without the loss of efficiency or extra administrative costs for IDEM or for the source. The source would still be required to comply with all existing permit terms, limits, and requirements. These changes would allow an exemption under state permitting rules. IDEM does not plan to seek approval of these changes by U.S. EPA. Therefore, sources using this exemption may not be exempt from federal permitting rules.
Although the main change proposed is to add a specific exemption to the rule as stated, IDEM has updated other standard language elsewhere in this section of the current rule.
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.
IC 13-14-9-4 Identification of Restrictions and Requirements Not Imposed under Federal Law
No element of the draft rule imposes a restriction or requirement on persons to whom the draft rule applies that is more stringent than a restriction or requirement imposed under federal law.
Potential Fiscal Impact
This rulemaking will have a positive fiscal impact for each source that would save on the cost and time of applying for a registration, permit modification, or variance for the repair or maintenance event each time there is an occurrence. The source could also minimize downtime if it could quickly change out a permitted emission unit without waiting for the permit modification for a short term condition. IDEM staff time and effort would be saved in reviewing and processing registration and permit requests.
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 (317) 232-8229 or (800) 451-6027 (in Indiana).

SUMMARY/RESPONSE TO COMMENTS FROM THE FIRST COMMENT PERIOD
IDEM requested public comment from July 20, 2016, through August 19, 2016, and from May 9, 2018, through June 8, 2018, on alternative ways to achieve the purpose of the rule and for suggestions for the development of draft rule language. IDEM received comments from the following party by the comment period deadline:
Robin Ridgway, Purdue University (PU)
Following is a summary of the comments received and IDEM's responses thereto:
Comment: The commenter stated support for IDEM's proposal to allow for a short term backup unit that is to be used during repair or maintenance of an emission unit or control device to qualify as an exemption under 326 IAC 2-1.1-3. The commenter also stated its willingness to work with IDEM on possible rule language. (PU)
Response: IDEM appreciates the support from the commenter that short term backup units should be able to qualify as an exemption as proposed in this rule.
