E-Permitting Retirement
AQD is retiring the e-permitting system over the next several months. The functional use of the system has degraded over time as the database of permit actions has expanded. A replacement system will be available in the future, but a date has not been set. The ability to initiate new applications will end on February 1, 2022. New account requests will not be approved beginning February 1, 2022.

Applicants will have continued use of the system to manage active applications and existing permits through April 1, 2022. After this date, permits in process that have not been issued will be transferred to normal application processing. Applicants using the system to store applications and permits will need to download documents prior to the April deadline or contact AQD E-Permit Help to make other arrangements.

Please note that through the pandemic period, AQD has allowed applicants to submit applications through the permitting contact page on the DEQ website: Contact Richard Kienlen and Phillip Fielder – Oklahoma Department of Environmental Quality. This ability will continue indefinitely.

Tier I Public Notice Guidance
AQD has developed implementation guidance for permitting under the new Tier I public notice requirements, effective September 15, 2021.
Produced Water Update
For tanks storing produced water and condensate/oil, DEQ will now require all applications submitted on or after April 15, 2021, to calculate breathing and working emissions assuming 100% of the tank throughput to be based on the properties of the condensate/oil which forms the free top layer. This requirement is in consideration of EPA guidance in AP-42, Section 7.1(11/19), Subsection

DEQ will no longer accept breathing and working emission calculations which are based on a condensate/oil-to-water ratio. This guidance does not apply to produced water tank flashing emissions or produced water tank truck loadout emissions. You may submit alternative emissions calculations for working and breathing losses with a technical justification and supporting documentation for a case-by-case approval.

AQD operates a dual permitting system — construction permits and operating permits — to control major and minor sources of air pollution.

  • A construction permit application is required before a new source is constructed or an existing source is modified.
  • AQD issues the construction permit after it is determined the source is designed to meet applicable rules and pre-construction requirements.
  • An operating permit is issued after construction is completed and demonstration is made that the source is capable of meeting applicable emissions limitations and air pollution control requirements.
