Who Regulates Air Emissions for Tustin Businesses

For regional permit and rule details consult the South Coast Air Quality Management District and contact City of Tustin Code Enforcement for local complaints. [1][2]

Key Compliance Steps for Businesses

  • Prepare for inspections: keep records, maintenance logs, and emissions monitoring results on site.
  • Budget for control equipment, compliance testing, and potential mitigation measures.
Begin with a process audit to identify all potential emission sources at your site.
