Rulemaking Associated with Reducing VOC Emissions from Fumigants

Back to Regulations to Reduce VOCs by Controlling Field Fumigant Emissions
Back to Volatile Organic Compound (VOC) Emissions from Pesticides

California is committed to reducing smog-producing emissions of volatile organic compounds (VOCs) from all sources, including pesticides. This prompted DPR to put regulations into place in January 2008 to reduce emissions from field fumigants, the largest single source of pesticide VOCs.


  • Regulations to reduce VOC emissions from field fumigants (approved and effective 1/25/08)
  • Amendments, PDF (20 kb) - phase in pesticide VOC reductions between 2008 and 2012 in the Ventura ozone nonattainment area.(approved and effective 9/3/08)
  • Amendments, PDF (22 kb) - revise the total pesticide (fumigant and nonfumigant) VOC emissions benchmarks in all ozone nonattainment areas that are used to reduce pesticide fumigant emissions, and delay fumigant limits and allowances in all ozone NAAs except Ventura until 2011. (approved and effective April 20, 2009)
  • Amendments - revise existing field fumigation methods; amends triggers for fumigant limits in nonattainment areas and the allowance system used to enforce the fumigant limits; and cleans-up sections pertaining to licensing and pesticide use reporting requirements. (approved and effective April 7, 2011)
  • Amendments – revise existing field fumigation methods and remove language that was put on federal labels. (approved and effective April 1, 2016)
