Petroleum

The OPS Petroleum Program regulates petroleum storage facilities with USTs (underground storage tanks) that hold 110 gallons or more and ASTs (aboveground storage tanks) that hold between 660 and 40,000 gallons. We also enforce NFPA (National Fire Protection Association) codes for ASTs that hold between 60 and 660 gallons or 40,000+ gallons when they are installed for retail and non-retail fueling.

For information pertaining to items that do not fall under our jurisdiction, you may contact the Colorado Department of Public Health and Environment at 303-692-3331 or the Colorado Oil and Gas Conservation Commission at 303-894-2100.
