Out-Of-State Fuel and Colorado Vapor Pressure Requirements for the Winter/Spring Season
Fuel distributors, retailers or any other parties purchasing motor gasoline in states that
border Colorado need to be aware that gasoline fuel loaded outside of Colorado does not
always meet Colorado’s vapor pressure requirements and is not legal for either sale or use in
Colorado during the months in which the vapor pressure requirements do not align. To avoid
penalties for non-compliance, Colorado buyers must be mindful that other states’ fuel
requirements can be different from those in Colorado when ordering and purchasing fuel from
out-of-state sources.
