Reducing VOC Emissions from Field Fumigants

Back to Volatile Organic Compound (VOC) Emissions from Pesticides

Subscribe to receive periodic e-mail updates on activities of DPR's VOC Program.

Regulations to reduce emissions of volatile organic compounds (VOCs) from fumigant pesticides apply to applications of methyl bromide, 1-3 dichloropropene, chloropicrin, metam sodium, potassium N-methyldithiocarbamate (also called metam-potassium), dazomet, and sodium tetrathiocarbonate.

General information

  • Areas affected, PDF ("nonattainment areas")
  • Rulemaking and technical support documents

Fumigation methods – Field fumigant emissions are reduced in the five geographic areas with specific requirements on how fumigations must be done, prohibitions of some high-emission methods, and limits on other methods.

  • Fumigation methods allowed

Emission targets and allowances – DPR sets benchmarks for total pounds of pesticide emissions from May 1 to October 31 in five geographic areas. This can require restricting fumigant emissions by individual growers if emission reduction targets cannot be met by other means. It is currently not required.

Reporting of fumigation methods used – DPR tracks VOC emissions by requiring reporting of field fumigant application methods in certain areas.

  • Field fumigation method codes, PDF – These are the codes that must be included on your use reports when you apply fumigants
