New Temporary Closure Forms Available

We updated our Temporary Closure forms for USTs/ASTs and created a new Request for Temporary Closure Extension form.

Please take a moment to retrieve and review these forms on our Tank Compliance page. 

Please use the new Notice of Intent to Place Tanks into Temporary Closure forms for both Aboveground and Underground tanks going forward, as well as the Temporary Closure Extension Request form when appropriate. Please discontinue use of the older forms as they may be returned.


Qualified Service Technicians

Effective January 1, 2020, the majority of work performed on UST systems in Colorado must be conducted by a state-certified Qualified Service Technician. Tasks include, but are not limited to, the following:

  • Installation, repair, replacement, maintenance, and calibration of all UST leak detection monitoring equipment.
  • Repair or maintenance work on in use UST systems, including replacement of components such as spill buckets, overfill prevention devices, and ancillary piping components such as flex connectors and penetration fittings located within sumps and under-dispenser containment.
  • Annual monitoring system functionality testing and certification.
  • Secondary containment testing, including initial testing of newly installed secondary containment systems.

Individuals who would like to be certified as Qualified Service Technicians must submit an application to OPS with documentation showing he/she passed the PEI Entry-Level Service Technician Training Course and the PEI RP900 exam.


Changes to the UST Installer Certification Process

In addition to providing a copy of their current International Code Council (ICC) certificate, individuals applying for state certification as UST installers will be required to provide documentation of having passed the Petroleum Equipment Institute (PEI) RP100 “Recommended Practices for Installation of Underground Liquid Storage Systems” examination.

Effective January 1, 2020, certified Installers will need to renew their ICC certification every two years.


Policy 29 Approved

The Petroleum Storage Tank Committee voted to adopt Policy 29, effective March 18, 2019. 


Updated Proposed Changes to Reasonable Cost Guidelines

Public comments received will be presented for consideration to the Petroleum Storage Tank Committee at their meeting on May 17, 2019.


Updated Petroleum Guidance for Suspected Releases

The revised Petroleum Storage Tank Regulations become effective March 17, 2019, and they include changes to Article 4 for suspected release identification, reporting, and response to better align OPS regulations with EPA regulations.
