California has the most comprehensive pesticide regulatory system in the nation. The County Agricultural Commissioner is responsible for implementation of this statewide program at the local level. The Pesticide Use Enforcement Program includes annual registration of Agricultural and Structural Pest Control Businesses, Pest Control Advisors and Farm Labor Contractors that work in the County. The Program includes issuance of Restricted Materials Permits, Operator Identification Numbers (for non-restricted agricultural pesticides), and monitoring of pesticides applied in the County through a mandatory use reporting system. The Agricultural Commissioner's staff verifies compliance with pesticide laws by periodic inspections of pesticide applications, mixing and loading operations, employee headquarters inspections and inspection of pesticide storage facilities. Staff also investigates all reports of pesticide related illnesses, crop losses, pesticide drift and wildlife losses, as well as complaints of other alleged misuse of pesticides in the County that may be detrimental to human health and safety or the environment. It should be noted, however, that neither the County Agricultural Commissioner nor CDPR has jurisdiction over pesticides applied on or to any federal lands or facilities.
