Regional Operator Certification Handbook

The EPA Regional Operator Certification Handbook is intended to provide comprehensive guidance for those filling the role of EPA Regional Operator Certification coordinator. As the EPA Regional Operator Certification coordinator, it is important to understand the state’s Operator Certification requirements to best aid the state Operator Certification programs. The handbook provides resources, explanations, and history of basic tasks to help new EPA Regional Operator Certification coordinators understand their role and responsibilities including:

  • Overseeing state Operator Certification programs,
  • Ensuring that state Operator Certification programs meet the federally defined nine baseline standards, and
  • Reviewing Operator Certification program reports annually to ensure they meet the Safe Drinking Water Act (SDWA) initiatives.

The handbook also includes resources to help Regional coordinators provide support to state Operator Certification programs, to help them improve their programs, develop a robust water operator workforce, and support small systems.
