What are air pollution permits?

Air pollution permits are written authorizations issued by air pollution control agencies, such as the Ventura County Air Pollution Control District (APCD), to build, install, alter, replace, or operate equipment that emits or controls certain regulated air pollutants. The air pollutants regulated by the APCD are reactive organic compounds (ROC), oxides of nitrogen (NOx), carbon monoxide (CO), fine particulate matter (PM10), oxides of sulfur (SOx), and certain toxic air pollutants. The purpose of air pollution permits is to help ensure that regulated air pollutants do not harm public health and welfare or hinder progress towards achieving and maintaining clean air.

What is the APCD permit program?

The APCD has a two-step permit program:

If you are a facility owner or operator in Ventura County, and will have air-polluting equipment, you will need an Authority to Construct before you can construct, install, or modify that equipment. This gives  APCD staff an opportunity to determine if your project will comply with applicable APCD rules.

Helpful Hint: Residential construction projects do not need air pollution permits.

After your project is completed, but before you can begin operations, you will need a Permit to Operate. A temporary Permit to Operate may be issued so that an emissions test or an on-site APCD inspection can be conducted while your facility is operating. Upon finding that your facility is complying with applicable APCD rules, APCD staff will issue you a Permit to Operate, which will have enforceable conditions to help ensure that your facility will continue to comply with those rules.

Do I need an air pollution permit?

You will need an air pollution permit if your business or facility has or will have equipment or processes that emit any regulated air pollutants. Air pollution permits are needed for the following actions:

Helpful Hint: Air pollution permits issued by the APCD are not a part of the County of Ventura’s discretionary land use permit process. Moreover, you may need an air pollution permit from the APCD even if you do not need a land use permit from the County of Ventura or other governmental agency. If you need assistance in determining whether or not your project requires and APCD permit, please contact the APCD office.

What types of equipment and processes need air pollution permits?

Permit processing time ranges from 30 to 180 days, depending on the complexity of the application. You will be notified within 30 days after submission whether or not your application is complete. This notification will also include the name and telephone number of the APCD engineer who has been assigned to your application.

Refer to APCD Rule 42 (Permit Fees) for additional details regarding air pollution permit fees.

What happens after my air pollution permit is approved?

You will be able to construct and/or operate your facility. However, to ensure continuing compliance with APCD rules, your permit will be subject to annual renewal and your facility will be subject to periodic inspections by APCD inspectors.

What is the APCD’s Questionnaire (AB3205)?

It is a questionnaire that notifies the APCD about businesses that may need air pollution permits. State law (AB3205) prohibits city or county agencies from issuing building permits or Certificates of Occupancy unless APCD air pollution requirements are met. This helps prevent the installation of unpermitted sources of air pollution and unsupervised renovation and demolition of facilities containing asbestos.

Does APCD regulate asbestos removal?

Yes, asbestos is a hazardous air pollutant and its removal is regulated by the APCD through APCD Rule 62.7 (Asbestos - Demolition and Renovation). APCD’s asbestos removal requirements apply regardless of the need for either a discretionary land use permit from the County of Ventura or an air pollution permit from the APCD. Rule 62.7 applies to all renovation and demolition operations, including dwelling units involving 100 or more square feet of asbestos containing material. However, residential single-unit dwellings where the owner/occupant performs such operations are exempt. Click here for more information regarding project requirements for asbestos removal.
