Liquefied Petroleum Gas and Natural Gas Inspection Fee

This fee is charged on sales of odorized liquefied petroleum gas and natural gas for the Liquefied Petroleum Gas (LPG) and Natural Gas (NG) Inspection Fund, created to provide funding for the inspection of installations, calibration and adjustment of meters and dispensers, and testing. The fee is collected for the following fuels: liquefied petroleum gas (LPG), liquefied natural gas (LNG), and compressed natural gas (CNG). The Liquefied Petroleum Gas and Natural Gas Inspection Fee is imposed on purchases of LPG, LNG, CNG, and collected by distributors of liquefied petroleum gas (LPG), liquefied natural gas (LNG), and compressed natural gas (CNG) in Colorado.

The fee is currently set at a per tank truckload rate of $10, which is reported at $0.00125 per gallon or gallon equivalent. A tank truckload is defined as 8,000 gallons or, in the case of CNG, gallon equivalents. The fee is reported and paid on the Colorado Fuel Distributor Tax Return of the manufacturer or distributor who is responsible for reporting the gallons and remitting tax due on LPG, LNG, and CNG. The inspection fee is not charged for LPG and Natural Gas shipments exported from Colorado.

The inspection fees are deposited into the LPG and Natural Gas inspection Fund for inspections of newly installed and existing facilities and for investigations of accidents related to gaseous fuels.

The amount(s) due is calculated on a fuel distributor's fuel tax return (DR 7050) through the Revenue Online monthly filing. Payment is due by the 26th of the following month, at the same time the return is due. If the due date is a weekend or a legal holiday, then the following business day is the due date. The return and payment are submitted electronically each month.
