New Source Review Application Tools

These workbooks will help you prepare a complete NSR permit application, resulting in a more efficient case-by-case permitting process.

NSR Workbooks

As of June 1, 2019, an applicant must submit the Form PI-1 General Application (previously referred to as the NSR Application Workbook) for all permit and action types below. For all applications, if modeling is required, an Electronic Modeling Evaluation Workbook (EMEW) must be submitted with the application.

  • Minor NSR: Initial, Amendment, Renewal, Renewal/Amendment, Relocation/Alteration, Change of Location, Alteration, Extension to Start of Construction
  • Special Permit: Amendment, Renewal, Renewal/Amendment, Alteration, Extension to Start of Construction
  • De Minimis: Initial
  • Flexible: Initial, Amendment, Renewal, Renewal/Amendment, Alteration, Extension to Start of Construction
  • PSD: Initial, Major Modification
  • Nonattainment: Initial, Major Modification
  • HAP Major Source [FCAA Section 112(g)]: Initial, Major Modification
  • PAL: Initial, Amendment, Renewal, Renewal/Amendment, Alteration
  • GHG PSD: Initial, Major Modification, Voluntary Update

Our workbooks are comprehensive and interactive. As you answer questions, data fields adjust so that you only see sections that are applicable to your project.

The workbooks are assigned versions (the number before the decimal) and patches (the number after the decimal). New versions will be posted when something major has changed and the application materials would be inaccurate without the update. Patches will be posted for minor updates. When submitting your workbook, you can submit any workbook with the most recent version number, even if there are subsequent patch numbers. For example, you may submit Version 3.1 even if Version 3.2 is available (because both are under Version 3). However, if Version 4.0 becomes available in the future, you must update to that version.

Please note, the workbooks are compatible with Excel 2013 and newer and you can create a free Microsoft accountExit the TCEQ
