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.

  • 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.
