Title V operating permits

In November 1990 Congress completed a major redrafting of the federal Clean Air Act. Many of these changes dealt with stationary sources of air pollution. One of the most significant changes was the creation of the operating permit program in Title V of the Clean Air Act.

In January 2020, APCD revised the operating permit forms to improve the Title V application process. Find forms, instructions, and helpful resources to complete Title V applications below.

The forms were last revised on August 13, 2021. Applicants are required to use the most updated versions of the operating permit forms.

The Division no longer accepts old application forms. 

The new forms will have the following changes:

  • Review the “General Instructions on How to Use Forms” before starting an application.
  • The Division is requiring one hard copy and one electronic of the application package.
  • The electronic submittal shall contain the following:
    • The source shall submit a complete PDF copy of the full application including all signature pages with either digital signatures or a scanned ink signature.
    • The forms must also be submitted individually in Word format (either .doc or .docx).
  • The date received by the division will be the date the complete electronic submittal is received in the T5 email box.
  • Submit all forms to cdphe_apcd_title_v@state.co.us
