La. Rev. Stat. § 3:4672

A. No person shall use any commercial weighing or measuring device in the distribution, handling or sale of petroleum products unless it is true and accurate. The standard of weights and measures applied to commercial weighing and measuring devices shall be those adopted by the commissioner in regulations promulgated pursuant to this Chapter. The standard of weights and measures adopted by the commissioner shall be as stringent as those standards issued by the National Institute of Standards and Technology, the American Society for Testing and Materials, their successors, or any other federal or nonprofit agency that prepares and issues nationally recognized standards for weighing or measuring petroleum products.

B. It shall be the duty of the commissioner to seal and forbid the use of any inaccurate commercial weighing or measuring device until such time as the defect is corrected. The breaking of this seal shall be prima facie evidence of a violation of this Subpart. No person shall refuse to permit the commissioner to inspect and seal, if deemed necessary, any such commercial weighing or measuring device, or break the seal after being placed on the device.

C. For the purpose of strengthening and making the administration of this Subpart more effective, the commissioner is authorized to require, under regulation promulgated by him, the measuring, calibration, and determination of the capacity in gallons of any vehicle tank, as defined herein, and to require every person to produce evidence of this calibration when deemed necessary.

D. The provisions of this Subpart are not applicable to carriers-for-hire operating under valid common carrier certificates or contract carrier permits issued by the Louisiana Public Service Commission and not engaged in transporting gasoline, motor fuel, or any other petroleum products for the purpose of sale, use, or consumption within this state, and persons operating motor busses under franchises or licenses issued by municipalities.

E. No person shall sell, withdraw, or distribute petroleum products from a vehicle tank or from any fuel tank or auxiliary fuel tank for the purpose of distribution or sale, unless the vehicle tank has been measured and calibrated under the provisions of this Subpart. The failure of the owner of any vehicle tank, after notice by the commissioner in accordance with regulations promulgated by him, to submit a vehicle tank for measuring, calibrating, and determining capacity or for inspection under said regulations shall constitute a violation of this Subpart.

F. Proof of the fact that a vehicle tank has been measured and calibrated in compliance with this Subpart shall be a certificate issued by a licensed service agency.

G. Repealed by Acts 2004, No. 47, §2, eff. May 21, 2004.
