UST Class A & B - Operator Training Manual State of Colorado
AB Operator Training - CGRS

We have been a Colorado Division of Oil & Public Safety (OPS)-approved underground storage tank (UST) trainer since 2009, when OPS implemented UST Operator Training requirements. OPS requires all UST owners/operators to demonstrate a fundamental knowledge of UST systems and applicable regulations, as well as that their UST systems receive monthly and annual UST inspections.

One of CGRS’s top UST experts administers our specialized-training program for owners/operators. We stay up to date on all the new changes as the state implements them, so our UST class attendees learn about the latest regulations.

CGRS Compliance Services team members are available and highly capable to perform monthly and annual testing and repairing UST and aboveground tank systems to ensure customers are and remain compliant with state regulations.

To access Colorado’s most recent regulations, documents and forms, visit the Colorado Division of Oil and Public Safety’s web page.

We specialize in the following UST training and contract services:

  • UST Operator Training Classes
  • Testing & Certification
  • Monthly and Annual Inspection Services
  • Document Management Services
  • Contract Operator Services

 CGRS will customize a training program designed specifically for your company.

CGRS has been helping underground petroleum tank systems owners/operators comply with EPA regulations since 1987 and its A&B Operator Training Classes are regarded by the industry as educational, effective and even entertaining. A/B operator certification is required for anyone who is in charge of the day-to-day compliance of a UST system.
