Air permits for storage tanks

A complete permit application must include all applicable elements on Form APCD-100.

Air Pollution Emission Notice (APEN) Forms

Use an APEN to apply for a new permit; request a modification to an existing permit; complete a routine (five-year) renewal for an existing permitted source or report changes in emissions, production or equipment.


Condensate Storage Tank APEN (Form APCD-205)  |  Guidance

  • Condensate is defined as hydrocarbon liquid with an API gravity greater than or equal to 40.


Crude Oil Storage Tank APEN (Form APCD-210)  |  Guidance

  • Crude oil is defined as hydrocarbon liquid with an API gravity less than 40.


Produced Water Storage Tank APEN (Form APCD-207)  |  Guidance


E&P storage tank APEN addendum (Form APCD-212)

  • Attach this form to your storage tank APEN if you need to report additional wells.


General Permits for Storage Tanks

General Permits offer a streamlined approach to air emissions permitting. Review the general permit to determine if your equipment and facility meet the applicability requirements. 


GP01: Condensate Storage Tanks

GP05: Produced Water Storage Tanks

GP08: Oil & Gas Industry Storage Tanks

  • GP08 can be used for condensate, crude oil or produced water.

Operating and Maintenance Plans

An O&M plan is required for all process units with emission controls at a synthetic minor or major stationary source. Visit the Oil and gas Operating & Maintenance Plan forms page for guidance and more information.

Request an alternative emissions control device

The division will consider, on a case-by-case basis, alternative emissions control equipment to meet control requirements of Regulation No. 7. The operator must obtain approval to use the alternative emissions control equipment prior to use.


Refer to PS Memo 15-03 for pollution control equipment requirements of Regulation No. 7, Part B, Section II, including alternative controls.
