Basic and Special Application Forms

Permit applications should include appropriate basic forms and may need to include special forms. The different types of forms are described below. You can download the forms you need from the IDEM Agency Forms page. If you have any questions, please contact OAQ for assistance.

Basic Forms

  • General Source Data (GSD) Forms: Intended to gather all of the general information about the source of air pollution. For a new (i.e., greenfield) source, it may be necessary to complete nearly all of these general forms. For an existing source that is only modifying a portion of the facility or making changes to the air permit, only those forms relating to the change are needed. Every air permit application packet should include a completed Air Application Forms Checklist, a completed Air Permit Application Cover Sheet, and a completed GSD-01 form. If you are required to notify adjoining landowners or occupants pursuant to 326-IAC-2-1.1-6(d) [PDF] and IC 13-15-8, then include a completed GSD-13 form and a completed GSD-14 form as part of your application packet.
  • Process Information (PI) Forms: The PI forms are intended to gather detailed information about specific processes that cause air pollution. Only those forms relating to the processes present at the source of air pollution are needed.
  • Control Equipment (CE) Forms: The CE forms are intended to gather detailed information about the air pollution control devices used. Only those forms relating to the equipment used to control air pollution at the source are needed.
  • Compliance Determination (CD) Forms: Part 70 (Title V) sources are required to submit certain compliance related information with each air permit application submitted to OAQ.

Special Forms/Documents

  • MACT Preconstruction: MACT approval is required when an owner or operator proposes to construct or reconstruct an emissions unit or emissions units that are a major new affected source or major reconstructed affected source under one of the MACT standards contained in 40 CFR Part 63. The approval under 40 CFR 63.5 is only required if the proposed new or reconstructed affected source in and of itself has the potential to emit greater than 10 tons per year of a single hazardous air pollutant (HAP) or greater than 25 tons per year of a combination of HAPs.
  • BACT Analysis Application: BACT analysis documents need to be completed by an applicant if the proposed new construction is subject to 326-IAC-2-2-3 [PDF] Prevention of Significant Deterioration (PSD), 326-IAC-2-3-2 [PDF] Emission Offset, or 326-IAC-8-1-6 [PDF] New Facilities, General [VOC] Reduction Requirements.
  • Prevention of Significant Deterioration / Emission Offset Checklist: Needs to be completed if the proposed new construction is subject to 326-IAC-2-2 [PDF] Prevention of Significant Deterioration (PSD) or 326 IAC 2-3 [PDF] Emission Offset.
  • Interim Approval: Certain types of sources may apply for an Interim Approval subject to the requirements of 326-IAC-2-13-1 [PDF]. This type of approval allows the applicant, under certain limited circumstances and at their own risk, to commence construction of a new emissions unit at an existing source or modification of an emissions unit at an existing source while the permit application is being reviewed.
  • Emission Credit Registry: The Indiana Emission Credit Registry is a tool created to assist sources looking for emission offsets for nonattainment New Source Review (NSR) permitting.
  • Phase II Acid Rain Permit Renewal Information: Each regulated power plant should submit a Phase II permit renewal application at least six (6) months prior to the expiration date of the source's Phase II Acid Rain Permit. Pursuant to Title 40, Part 72, Subpart G, Section 72.73 (b)(2) of the Code of Federal Regulations (40 CFR 72.73), Phase II Acid Rain Permits expire five (5) years after the effective date of the original permit. Even if the permit has been amended or revised, the expiration date is dependent on the original Phase II Permit effective date. For example, a Phase II Permit that was effective on January 1, 2000 would expire on January 1, 2005; therefore, the renewal application should be submitted by April 1, 2004. A renewal fee is not required with the application.
  • Summary of Federal Requirements: Used to identify applicable New Source Performance Standards (NSPS) and/or National Emission Standards for Hazardous Air Pollutants (NESHAPs).
  • Initial Notification: May be required according to 40 CFR Part 63, Subpart A — National Emission Standards for Hazardous Air Pollutants (NESHAPs) for Source Categories, Subpart A — General Provisions.
  • Source Specific Operating Agreement (SSOA) Forms

The following options may be available to sources that wish to limit their potential to emit (PTE) below major source thresholds:

  • A Federally Enforceable State Operating Permit (FESOP) issued under 326-IAC-2-8 [PDF].
  • A Source Specific Operating Agreement (SSOA): Source Specific Operating Agreement (SSOA) Application forms need to be completed if the applicant is constructing a new source and elects to comply with the SSOA rules codified in 326-IAC-2-9 [PDF].
  • A Permit By Rule (PBR) under 326-IAC-2-10 and 326-IAC-2-11 [PDF]. A PBR under 326 IAC 2-10 does not exempt the source from needing a construction permit. A new source wishing to operate under a PBR under 326 IAC 2-10 must first obtain a construction and operating permit and hold the operating permit for twelve months of operation before transitioning to a PBR. Some PBR under 326 IAC 2-11 may not need a construction permit.
