Air Toxics Program

Applicability

Facilities are subject to AB 2588 if they meet the applicability criteria outlined in CARB’s Emission Inventory Criteria and Guidelines Regulation (EICG) to determine.

Facilities are subject to quantifying and reporting their toxic emissions if one or more of the criteria below is met:

  • Emit 10 or more tons per year of criteria pollutants (particulate matter, oxides of nitrogen, oxides of sulfur, or organic gasses).
  • Emit less than 10 tons per year of criteria pollutants, but meet one or more of the classes listed in Appendix E of the EICGR.

Facilities may be reinstated in the AB 2588 program if any of the following criteria are met:

  • Emit toxic substances that have been added to Appendix A of the EICGR since their last evaluation.
  • Emit toxic substances that have new health risk values published by the state’s Office of Environmental Health Hazard Assessment (OEHHA).
  • A sensitive receptor has been established or constructed within 500 meters of the facility after the facility became exempt.
  • A significant change has occurred in the emission measurement or emission quantification methodology applicable to the facility, as determined by the District.
  • A significant change has occurred in air dispersion modeling or related exposure modeling methodology, as determined by the District.
  • A significant change has occurred in OEHHA health risk assessment methodology.
  • The facility has increased its emissions of a substance listed in Appendix A and the District determines and notifies the facility that the increase may create a risk to the community that must be evaluated.
