Technical Consultation

Technical consultations are one of the many ways South Coast AQMD helps businesses meet today’s air quality standards. South Coast AQMD’s Small Business Assistance Office offers free technical consultation services either on-site, by phone, or at South Coast AQMD headquarters to help business owners:

  • Determine if equipment, process(es) and/or operations require permitting and/or registration, or are exempt from regulation.
  • Assist with understanding permit conditions and rule requirements.
  • Provide business operators with a compliance determination by identifying areas of non-compliance.
  • Assist business operators in developing strategies to achieve compliance with South Coast AQMD rules and regulations.
  • Assist business operators with proper recordkeeping necessary to comply with permit conditions.
  • Provide assistance and liaison with other agency staff on permit processing, application filing, regulatory compliance, and fee issues.

All businesses with 100 or fewer employees or with annual gross revenues up to $5 million are eligible for this free on-site, and over-the-counter, or phone technical consultation service.

What to expect when help arrives

Your Small Business Representative will review South Coast AQMD rules and regulations which apply to your facility. During a walk-through of your facility, you and your South Coast AQMD representative will identify problem areas, evaluate pollution reduction responsibilities, and work together to find permanent, effective solutions. If something needs to be corrected, no tickets or fines will be issued, but you must agree in advance to correct the violations as quickly as possible. We generally allow two weeks to comply, and will also help you with your request for a variance from our Hearing Board if it will take more time.


Be sure to call your Small Business representative if you need additional help. He or she may also check with you from time to time to see if you need further compliance assistance. Ultimately, you are responsible for correcting any non-compliant conditions.
