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

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.

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

Version 6.1 is the current version of the Form PI-1 General Application. Version 6.0 will also be accepted; however, we strongly recommend using v6.1. Changes made to each version and patch are summarized here: Updates on Form PI-1 General Application.

Important: the files posted below are Version 6.1. If this version number does not match the version number listed on the Cover sheet of the workbook, please clear your browser cache or refresh your screen.

There are three versions of the PI-1 available to choose from that accommodate different numbers of Facility Identification Numbers (FINs), and Emission Point Numbers (EPNs) in a permit. Select the file that is large enough to include all of the FINs and EPNs in the permit (not the project).

Tips for Completing the Form PI-1 General Application

Step-by-step guidance videos for completing the Form PI-1 General Application.

TCEQ may not accept incomplete applications. Please ensure that the application is submitted using the applicable workbook and includes completed information, attachments, and information required for public notice.

Electronic Modeling Evaluation Workbook (EMEW)

All minor projects utilizing modeling to complete an impacts analysis must include an EMEW with the application submittal.
We are currently accepting the March 2019 version (Version 2.0) and forward of the EMEWs. However, v3.0 has been released and will become mandatory on July 1, 2025. Changes made to each version and patch of the EMEWs can be viewed here: Updates on EMEWs

If the permit application is required to be submitted through STEERS, the EMEW or modeling protocol (if PSD review is triggered) and any supplemental attachments (except modeling files) must be submitted as an application attachment in STEERS. All modeling files accompanying an EMEW/modeling protocol should be submitted utilizing TCEQ FTPS (for initial submittal, share with apirt@tceq.texas.gov). Information accompanying an EMEW/modeling protocol should be submitted at the same time as the application submittal. Note modeling files are highly recommended but not required for application submittal.

There are two different EMEWs available: one for SCREEN3 and one for Non-SCREEN3.
The files posted below are version 3.0. If this version number does not match the version number listed on the General sheet of the workbook, please clear your browser cache or refresh your screen.

The workbook identifies information required for the air quality modeling submittal using SCREEN3 and identifies key information required for a complete air quality submittal.

The workbook identifies information required for the air quality modeling submittal using AERMOD, AERSCREEN, or ISC/ISCPrime and identifies key information required for a complete air quality submittal.

Step-by-step guidance videos for completing the EMEWs.

Please send all feedback or questions on the EMEWs to ADMod@tceq.texas.gov
