Air Operating Permits Register Entries
The Permit Register includes all actions the permitting authority takes on a facility's permit application. These actions may include completion of the draft and final permit, the scheduling of hearings and public meetings, and modifications to the permit. The Permit Register also informs the public about how to be involved in the operating permit process.
Ecology issues a new Permit Register on the 10th and 25th of each month, or the nearest date, when there are entries.
Please submit your Air Operating Permit Register Entry Electronically.
To be placed on an electronic mailing list notifying you of register entries, please email your email address. Enter "AOP" in the subject line of the email.
An Air Operating Permit combines in one document all the operational and procedural requirements, emission standards and other requirements for facilities of a certain size that release air pollution.
A facility is required to obtain an Air Operating Permit if it has the potential to emit any of the following:
If a facility has the potential to emit these amounts, but actually emits less, its operator/owner can ask to be authorized to operate without an air operating permit. Local and state air pollution control requirements will still apply. This action will be included in the Permit Register.
Facilities that have the potential to emit more than the thresholds for major source status, but actually emit less, can ask for and receive a legal order from the permitting authority. The order will place limits on the operation of the facility and the emissions will be limited to below the thresholds. Examples of limitations could be: limits on the hours of operation, limits on types of solvents allowed at a facility, requirements to install and use the latest air pollution control device, or changes in fuel makeup in order to be considered synthetic minor sources.
The U.S. Environmental Protection Agency has authorized Ecology and local air authorities to administer the Air Operating Permit Program. Either Ecology or a local agency writes the permits. For more information about an individual permit action found in the Permit Register, contact the appropriate local air authority or Ecology regional office.
For older register entries please email me your request, we have historical records from 1996.
