C.R.S.
Section 8-20-218
Calibration of transport, tank truck, or delivery trucks
(1)
The director of the division of oil and public safety shall calibrate transport, trailer, and delivery truck tanks to determine the legal capacity of each compartment, allowing for expansion outage to conform to DOT regulations, except in the case of delivery truck tanks where two percent outage will suffice. Each tank compartment shall have affixed and spot-welded by the owner or operator thereof a capacity marker, which shall be set by measuring with a steel rule from the bottom of a steel bar set across the fill opening to the bottom of the marker (floated). The compartment gallonage shall be marked or stenciled with paint in figures at least one inch in height on each compartment dome collar.(2)
All new or additional vehicular tanks purchased or leased after April 6, 1955, by any person for hauling class I, II, or III petroleum products within or into the state shall be calibrated by the director of the division of oil and public safety and a certificate of calibration shall be issued to the owner or operator thereof before such equipment is put in service. A copy of the certificate of calibration shall accompany the tank at all times.(3)
Whenever a certificate of calibration has been lost or mutilated, the director of the division of oil and public safety shall issue a duplicate of the original which shall serve the purpose of the original. The director of the division of oil and public safety may order, after proper inspection, a calibration or a recalibration of any transport, trailer, or delivery truck tank operating in the state, whether calibrated by the director previously or not, when inspection by the director or the director’s deputy reveals that tank compartments or capacity markers have been altered intentionally or accidentally, and the owner or operator shall comply with such order within ten days. If the owner or operator of a delivery truck tank has available calibrating equipment acceptable to the director of the division of oil and public safety, the tanks shall be calibrated in the presence of the director or the director’s deputy, at or near the place of business of the owner or operator, and the director shall issue a certificate of calibration for said tank.
