Overview of Permit Renewal

Certain Air District permits require renewal or action prior to expiration.  This applies to Authorities to Construct (A/C), Permits to Operate (P/O), Certificates of Registration and Major Facility Review (Title V) Permits.

Here is an overview of the renewal process:

Authority to Construct (A/C) - If any equipment covered in the A/C is not completed before it expires, then you must notify the Air District prior to expiration. If an A/C does not qualify for renewal, the applicant must obtain a new A/C by resubmitting a new permit application. See Air District Regulation 2, Rule 1. The Air District will issue an invoice for the A/C renewal after the notification is received.

Permit to Operate (P/O) - Prior to receiving an invoice to renew the P/O, you may be asked to provide information through the Data Update process. The renewal invoice is typically issued 30 to 60 days prior to expiration.

Certificate of Registration (Registration) - Depending on the type of equipment registered, notification to renew a Registration is either done by e-mail or by the issuance of a renewal invoice. The renewal invoice is typically issued 30 to 60 days prior to expiration. For registrations that are also included on a P/O, the registrations will be renewed at the same time as the P/O.

Major Facility Review (Title V) Permit - This type of permit is renewed every 5 years.The Responsible Official must submit an application to renew the Title V permit no later than 6 months and no earlier than 12 months from expiration. The Air District will issue an invoice for the renewal during the process.

Data Update

Prior to receiving an invoice to renew a P/O, the Air District may periodically ask for information through a ‘Data Update’, which is typically sent 110 to 150 days prior to permit expiration.  Data is typically updated every 1 to 4 years, depending on the device.  Not all devices (sources) require updating during this process and may not be listed in the Data Update.  The information you furnish is used to:

  • Update the facility's emissions inventory
  • Calculate permit renewal fees
  • Check compliance with applicable regulations and permit conditions
  • Comply with the Air Toxics "Hot Spots" Information and Assessment Act (AB 2588)
