MS Code § 27-55-35 (2020)
2020 Mississippi Code|Title 27 - Taxation and Finance|Chapter 55 - Gasoline and Motor Fuel Taxes|Article 1 - Gasoline Tax|§ 27-55-35. Metering requirements

 A gallonage measuring meter shall be installed on each pipeline used for the withdrawal of gasoline subject to excise taxes provided in this article from the storage tank of any refinery, pipeline terminal, water terminal, or any terminal that does not have stationary bulk storage tanks at such terminal within the State of Mississippi, and no gasoline shall be withdrawn except through said gallonage measuring meters. No bypass installation shall be constructed around the meters. Said meters shall be installed and maintained as required by the comptroller, and shall be sealed by him or his agents. In case of a breakdown or mechanical impairment of any such meters, the owner or operator of the terminal or refinery shall give notice to the comptroller of such breakdown or mechanical impairment within twenty-four (24) hours after such breakdown or impairment becomes known to the owner or operator, and such meters shall be repaired and reinstalled or replaced within thirty (30) days from the time such breakdown or mechanical impairment becomes so known. The comptroller, or his agent, shall maintain a close watch over the receipt and withdrawal of gasoline products during such period of breakdown or mechanical impairment. Provided, however, this section shall not apply to withdrawal lines used exclusively for withdrawal of liquefied petroleum gases.   The owner or operator of each refinery or terminal in the State of Mississippi shall have installed and maintained, according to the requirements of the comptroller, at said refinery or terminal a prover tank for the purpose of proving the accuracy of measurement of the said meters. The comptroller, or his agent, shall have the use of the prover tank at any reasonable time of the day for the purpose of checking the accuracy of measurement of said meters. He is further given the authority to verify the accuracy of any prover tank or tanks.   The comptroller shall have the authority to use services of any recognized calibrating agency for the purpose of determining whether or not the prover tank or tank system provided for herein is properly constructed and installed.   It shall be unlawful for any person to break any seal placed upon any meter installed under the provisions of this section, except in the presence of an agent of the comptroller or in the presence of some person whom the comptroller has specifically authorized to be present and act for him. It shall also be unlawful for any person to withdraw any taxable gasoline from storage tanks as covered by this article except through the meters prescribed herein. The violation of any of the provisions of this section shall constitute a misdemeanor and, upon conviction, such person shall be subject to fine of not less than Five Hundred Dollars ($500.00) nor more than One Thousand Dollars ($1,000.00) or to imprisonment for not more than sixty (60) days in jail, or to both such fine and imprisonment. Notwithstanding anything to the contrary contained in this section, the comptroller may, in his discretion, waive the penalty for breaking in an emergency any seal placed upon any meter installed under the provisions of this article, provided the person breaking the same notifies the comptroller, in writing, that he has done so within twenty-four (24) hours after the time such seal is broken.
