Permit applications

(a) Confidential information. If a source submits information to the DEQ under a claim of confidentiality, the source shall also submit a copy of such information directly to the Administrator, if the DEQ requests that the source do so. (b) Duty to supplement or correct application. Any applicant who fails to submit any relevant facts or who has submitted incorrect information in a permit application shall, upon becoming aware of such failure or incorrect submittal, submit such supplementary facts or corrected information within 30 days unless the applicant's request for more time has been approved by the DEQ. In addition, an applicant shall provide additional information as necessary to address any requirements that become applicable to the source after the date it filed a complete application but prior to release of a draft permit. (c) Standard application form and required information. Sources that are subject to the Part 70 permit program established by this Chapter shall file applications on the standard application form that the DEQ makes available for that purpose. The application must include information needed to determine the applicability of any applicable requirement, or state-only requirement, or to evaluate the fee amount required under the schedule approved pursuant to OAC 252:100-5- 2.2(b)(2). The applicant shall submit the information called for by the application form for each emissions unit at the source to be permitted. The source must provide a list of any insignificant activities that are exempted because of size or production rate. Trivial activities need not be listed. The standard application form and any attachments shall require that the information required by OAC 252:100-8-5(d) and/or (e) be provided. (d) Construction permit applications. (1) An application for a construction permit shall provide data and information required by this Chapter and/or requested on the application form available from the DEQ pursuant to the requirements of this Chapter. Such data and information shall include but not be limited to site information, process description, emission data and when required, BACT, modeling and sampling point data as follows: (A) BACT determination. To be approved for a construction permit, a major source must demonstrate that the control technology to be applied is the best that is available for each pollutant that would cause the source to be defined as a major source. This determination AQAC_2026_JUL_SC_7_8_10_RUL 9 June 15, 2026 will be made on a case-by-case basis taking into account energy, environmental, and economic impacts and other costs of alternative control systems. Unless required under Part 7 of this Subchapter, a BACT determination is not required for a modification that will result in an increase of emissions of less than 100 tons per year of any regulated air pollutant. GHGs only trigger a requirement for a BACT determination under the circumstances described in Part 7 of this Subchapter (Prevention of Significant Deterioration or PSD). (B) Modeling. Any air quality modeling or ambient impact evaluation that is required shall be prepared in accordance with procedures acceptable to the DEQ and accomplished by the applicant. GHGs, either as individual pollutants or as an aggregate, are exempt from the requirements for air quality modeling and ambient impact evaluation. (C) Sampling points. If required by the DEQ an application shall show how the new source will be equipped with sampling ports, instrumentation to monitor and record emission data and other sampling and/or testing equipment. (2) Construction permit applications for new sources must also include the requirements for operating permits contained in OAC 252:100-8-5(e) to the extent they are applicable. (3) Construction permit applications for existing source modifications that are eligible for the enhanced NSR process under 252:100-8-4(c) must indicate in the application whether they intend to utilize: (A) the enhanced NSR process, including the public notice procedures of OAC 252:4-7- 13(g)(4) and the administrative amendment process for the ensuing operating permit modification, or (B) the traditional NSR process. (4) Construction permit applications for existing sources where the construction permit will, on issuance, generate one or more Emission Reduction Credits (ERCs) must follow all applicable requirements of OAC 252:100-10-4, 10-5, and 10-6. (e) Operating permit applications. (1) Identifying information, including company name and address (or plant name and address if different from the company name), owner's name and agent, and telephone number and names of plant site manager/contact. (2) A description of the source's processes and products (by two-digit Standard Industrial Classification Code) including any associated with each alternate scenario identified by the source. (3) The following emissions-related information: (A) All emissions of pollutants for which the source is major, and all emissions (including fugitive emissions) of regulated air pollutants. Fugitive emissions shall be included in the permit application and the permit in the same manner as stack emissions, regardless of whether the source category in question is included in the list of sources contained in the definition of major source. The permit application shall describe all emissions of regulated air pollutants emitted from any emissions unit, except where such units are exempted under OAC 252:100-8-5(c) or OAC 252:100-8-3(b). (B) Identification and description of all points of emissions described in OAC 252:100-8- 5(e)(3)(A) in sufficient detail to establish the basis for fees and applicability of the Act's requirements. (C) Emissions rates in tons per year and in such terms as are necessary to establish compliance consistent with the applicable standard. AQAC_2026_JUL_SC_7_8_10_RUL 10 June 15, 2026 (D) The following information to the extent it is needed to determine or regulate emissions: (i) fuels, (ii) fuel use, (iii) raw materials, (iv) production rates, and (v) operating schedules. (E) Identification and description of air pollution control equipment and compliance monitoring devices or activities. (F) Limitations on source operation affecting emissions or any work practice standards, where applicable, for all regulated pollutants at the covered source. (G) Other information required by any applicable requirement, or state-only requirement (including information related to stack height limitations developed pursuant to section 123 of the Act). (H) Calculations on which the information in items (A) through (G) of this paragraph is based. (4) The following air pollution control requirements: (A) Citation and description of all applicable requirements and all state-only requirements. (B) Description of or reference to any applicable test method for determining compliance with each applicable requirement and state-only requirement. (5) Other specific information required under the DEQ's rules and statutes to implement and enforce other applicable requirements of the Act or of this Chapter or to determine the applicability of such requirements. (6) An explanation of any proposed exemptions from otherwise applicable requirements and state-only requirements. (7) Additional information as determined to be necessary by the DEQ to define alternative operating scenarios identified by the source pursuant to OAC 252:100-8-6(a)(9) or to define permit terms and conditions implementing OAC 252:100-8-6(f) or 252:100-8-6(a)(10). (8) A compliance plan for all covered sources that contains all the following: (A) A description of the compliance status of the source with respect to all applicable requirements and state-only requirements as follows: (i) For applicable requirements and state-only requirements with which the source is in compliance, a statement that the source will continue to comply with such requirements. (ii) For applicable requirements and state-only requirements that will become effective during the permit term, a statement that the source will meet such requirements on a timely basis shall satisfy this provision, unless a more detailed schedule is expressly required by the applicable requirement. (iii) For requirements for which the source is not in compliance at the time of permit issuance, a narrative description of how the source will achieve compliance with such requirements. (B) For sources not in complete compliance, a compliance schedule as follows: (i) A schedule of compliance for sources that are not in compliance with all applicable requirements and state-only requirements at the time of permit issuance. Such a schedule shall include a schedule of remedial measures, including an enforceable sequence of actions with milestones, leading to compliance with any applicable AQAC_2026_JUL_SC_7_8_10_RUL 11 June 15, 2026 requirements and state-only requirements for which the source will be in noncompliance at the time of permit issuance. This compliance schedule shall resemble and be equivalent in stringency to that contained in any judicial consent decree or administrative order to which the source is subject. Any such schedule of compliance shall be supplemental to, and shall not sanction non-compliance with, the applicable requirements on which it is based. (ii) A schedule for submission of certified progress reports no less frequently than every 6 months. (C) The compliance plan content requirements specified in this paragraph shall apply and be included in the acid rain portion of a compliance plan for an affected source, except as specifically superseded by regulations promulgated under Title IV of the Act with regard to the schedule and method(s) the source will use to achieve compliance with the acid rain emissions limitations. (9) Requirements for compliance certification, including the following: (A) A certification of compliance with all applicable requirements and state-only requirements by a responsible official consistent with OAC 252:100-8-5(f) and section 114(a)(3) of the Act; (B) A statement of methods used for determining compliance, including a description of monitoring, recordkeeping, and reporting requirements and test methods; (C) A schedule for submission of compliance certifications during the permit term, which shall be submitted annually, or more frequently if required by an underlying applicable requirement state-only requirements or by the permitting authority; and (D) A statement indicating the source's compliance status with any applicable enhanced monitoring and compliance certification requirements of the Act.
