Pesticide Use & Enforcement Program
Operator Identification Numbers & Restricted Materials Permits
Prior to purchasing or applying pesticides, growers and businesses must obtain or renew an operator identification number (OP ID) or restricted materials permit (RM). The annual renewal process begins by appointment in December. During the renewal contact information, sites, compliance agreements, crop statistics and pesticides are reviewed and updated.

Private Applicator Certification (PAC)
Growers who use restricted materials, have employees that apply pesticides, or employees who work in pesticide-treated fields are required to have a private applicator certificate (PAC). The PAC exam is administered, in English and Spanish, in our office, Monday-Friday 8-3PM. The certificate is valid for three-years and may be renewed with 6 hours of continuing education or by re-examination.
Training & Outreach
Each year, the Agricultural Commissioner's Office sponsors continuing education classes geared toward providing credits for private applicator certificate holders and State Licensees. In partnership with industry and educational groups we have created a multitude of outreach and educational events.
Effective and comprehensive pesticide use compliance monitoring is essential for the safety of pesticide handlers, fieldworkers, the public and the environment. Our office inspects both agricultural and non-agricultural settings to ensure compliance with all safety regulations. Our office performs pesticide application, field worker safety, pesticide storage and disposal, as well as annual records inspections.
Compliance & Enforcement
Our office strives to ensure "compliance through education," however if those efforts fail several compliance or enforcement actions may be taken. Compliance actions include letters of warning, notices of violation, and documented compliance interviews. If the case involves serious worker safety violations or environmental or property damage, an enforcement action may be warranted. When an enforcement action is initiated, a Notice of Proposed Action (NOPA) is drafted that outlines the violations, and a fine is proposed. Those who are issued a NOPA are afforded due process rights. 3CCR 6130 and 6128 respectively.
