Overview of Permit Renewal

Certain Air District permits require renewal or action prior to expiration. This applies to Authorities to Construct, Permits to Operate, 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. In addition, the applicant must provide notification when any equipment covered by the A/C is started up or if the A/C is no longer needed. For more information, go to the Authority to Construct (A/C) web page.

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 (see section below). Starting in 2021, some facilities will be required to submit calendar year reporting under the California Air Resources Board’s Criteria Pollutant and Toxics Emissions Reporting (CTR) rule. For more information on CTR reporting, go to the Criteria Toxics Reporting web page.

The renewal invoice is typically issued 30 to 60 days prior to expiration. Delays in the submittal of your Data Update may cause your permit renewal invoice to be issued late. Failure to return your Data Update may result in enforcement action or prevent your permit renewal invoice from being issued.

Certificate of Registration (Registration) – If your facility is only covered by a registration, you will be issued a renewal invoice typically sent 30 to 60 days prior to expiration. For registered equipment and operations that are also included on a P/O, the registrations will be renewed at the same time as the P/O.

Major Facility Review (MFR or 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 Title V renewal during the process.

Data Update

Unless your facility is subject to Criteria Air Pollutants and Toxic Air Contaminants (CTR) reporting, 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. The Data Update is sent to the designated owner/operator. Data is 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)

Trade Secret: Under the California Public Records Act, all information in your submittal will be considered a matter of public record and may be disclosed to the public, unless you have asked the Air District to treat certain items as trade secret as specified in Regulation 2, Rule 1, Section 402.7.

  • Each page containing trade secret information must be labeled “trade secret” with the trade secret information clearly marked and you must provide a “public copy” with the information redacted.
  • For each item asserted to be trade secret, you must provide a statement which provides the basis for your claim.
