All Unit Attribute Forms

Some Title V Operating Permits require Unit Attribute (UA) Forms, Unit Attributes 1-66 Forms and Instructions are available on this page. When entering citations, please do not use abbreviated or condensed citation entries.

NEW Note: As of July 2025, all Unit Attribute (OP-UA) forms will now be available in an Excel format, as well as the previously available format of PDF and Word. After October 1, 2025, the PDF and Word versions of all OP-UA forms will begin to be removed as updates are made for any rule changes. After February 1, 2026 only the Excel versions will be available and accepted.

Please note the following for the different formats of OP-UA forms in the table below:

  • New OP-UA Excel workbooks:
    • Each OP-UA workbook includes the OP-SUM and OP-REQ2 forms within them.
    • Each OP-UA workbook has an accompanying PDF instructions document specific for that OP-UA form. Instructions for the OP-SUM and OP-REQ2 have been incorporated into the associated OP-UA Instructions.
  • Old version of OP-UA forms:
    • The OP-UA Form Tables in the PDF format will be available for a period of time. These versions do not include the OP-SUM and OP-REQ2 forms.

If an OP-UA form is only available in Excel, only the Excel version will be accepted.
