California’s Toxic Air Contaminant Act created the statutory framework for the evaluation and control of chemicals as toxic air contaminants (TACs). In implementing the law, DPR must determine the levels of human exposure in the environment and estimate the potential human health risk from those exposures. DPR’s evaluation report undergoes review by other government agencies, the public, and a Scientific Review Panel. DPR must then determine and implement the appropriate degree of control measures for the pesticide.

  • Background information:
    Description of TAC program, laws and regulations, and fact sheets

  • Control (risk management):
    List of toxic air contaminants and information on measures to mitigate exposure
  • E-Mail Updates
