Back to Air Program
Back to Air Quality Initiative

The Department of Pesticide Regulation (DPR) develops and implements regulatory requirements to control impacts of fumigants as both toxic air contaminants (TACs) and volatile organic compounds (VOCs).

  • General information
  • Chemical specific information
    • Chloropicrin – Requirements to control VOC emissions and toxic exposure are in effect.
    • 1,3-Dichloropropene (Telone) – Requirements to control VOC emissions and toxic exposure are in effect.
    • Methyl iodide – Requirements to control VOC emissions and toxic exposure are in effect.
    • Metam sodium and methyl isothiocyanate (MITC) – Requirements to control VOC emissions and toxic exposure are in effect.
    • Methyl bromide – Requirements to control VOC emissions and toxic exposure are in effect.
    • Sulfuryl fluoride – Interim measures to control toxic exposure are in effect.
  • Fumigant labeling and training information
    • 2012 field fumigant labels – The U.S. Environmental Protection Agency and DPR approved major revisions to fumigant labeling requirements in December 2010.
    • Fumigant management plan (FMP) templates – DPR FMP templates that comply with labeling and state regulatory requirements.
    • Fumigant training for county agricultural commissioner staff
    • U.S. Environmental Protection Agency (U.S. EPA) fumigant toolbox – U.S. EPA information on training, outreach, and other resource materials for applicators and handlers, communities, state and local agencies, and others interested in understanding and implementing the current requirements for safe use of soil fumigants.
