Spray Application

The Spray Applications Permit covers the point source discharge of biological and residual chemical pesticides to waters of the U.S. resulting from spray applications by the California Department of Food and Agriculture.  The permit does not cover California of Food and Agriculture discharges on tribal lands which are regulated by a federal permit.

Hot News!

The Spray Applications Permit will be expiring in February 2016 and upon reissuance will include the changes described below:

Picture of man spraying pesticides on plants.
  • Changing the permit from a general permit to an individual permit and naming the California Department of Food and Agriculture as the sole agency covered by the individual statewide permit;
  • Removing toxicity testing requirements based on toxicity studies conducted under the Vector Control Permit, Order 2011-0002-DWQ;
  • Regulating active ingredients instead of pesticide products, resulting in deletion of Attachment E which lists pesticide products regulated by the permit; and
  • Adding language that delegates the State Water Board's authority to the Executive Director or his/her designee to:
    • Add active ingredients that are registered by the California Department of Pesticide Regulation for spray applications and used by the California Department of Food and Agriculture. Add receiving water limitations to corresponding newly added active ingredients; and
    • Grant a regulatory exception to the California Department of Food and Agriculture from complying with pollutant receiving water limitations pursuant to the California Ocean Plan and/or the Policy for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of California.
