A. From and after July 1, 1990, there is imposed and the director shall collect an excise tax on the operation of underground storage tanks regulated under this chapter measured by the quantity of regulated substances placed in a tank in any calendar year. The tax is levied at the rate of one cent per gallon of regulated substance.
B. For proper administration of this article, and to prevent the evasion of the tax imposed by this article, it shall be presumed until the contrary is established by competent proof under rules and procedures adopted by the director that all regulated substances that are motor vehicle fuel as defined in section 28-101, aviation fuel as defined in section 28-101 and diesel as defined in section 28-6001, subsection B and that are refined, manufactured, produced, compounded or blended in this state, or imported into this state, will be placed in an underground storage tank from which the fuel is dispensed to users who consume the fuel and do not further distribute it. Under this presumption, the owner and operator of an underground storage tank from which motor vehicle fuel, aviation fuel or diesel is dispensed and from which no further bulk distribution will be made, shall be considered to have paid the tax collected under title 28, chapter 16, article 6.
C. The tax imposed by this article does not apply to underground storage tanks operated by the United States or this state or agencies of the United States or this state or to any of the following substances placed in underground storage tanks:
1. Naphtha-type jet fuel or kerosene-type jet fuel.
2. Regulated substances as defined in section 49-1001, paragraph 16, subdivision (b), unless such regulated substances were placed in an underground storage tank prior to July 1, 1997, and the owner or operator of the underground storage tank has paid prior to July 1, 1997 all taxes imposed by this article applicable to such regulated substances. If the owner or operator has paid those taxes, the owner or operator may elect to continue to pay the tax imposed by this article regarding such regulated substances.
D. The owner and operator of an underground storage tank regulated under this chapter are jointly and severally liable for the tax, but the owner and operator may agree between themselves and file a notarized affidavit with the director designating either the owner or operator as primarily responsible for the tax under this article.
E. Any person who purchases motor vehicle fuel as defined in section 28-101, aviation fuel as defined in section 28-101, or diesel as defined in section 28-6001, subsection B for which the tax imposed by this section has been paid and which fuel has been placed in a tank which is not subject to the underground storage tank tax imposed by this section and from which no further bulk distribution of the fuel will be made, may claim a refund of the tax levied. Refunds shall be submitted on forms prescribed by the director and shall be supported by substantiation for the amount of the tax paid.
F. Any person eligible to claim a refund of the tax imposed by this section, including an assignee of a refund claim, may assign such claim to the person from whom the fuel was purchased, and the assignee of the claim may claim the refund allowed under subsection E of this section provided that the assignor of the claim certifies in writing to the assignee, on forms prescribed by the director, that the assignor relinquishes all interest in the refund and shall not also claim a refund from the director.
G. If a refund claim is assigned to a person who is required to make payments under title 28, chapter 16, article 6, the refund shall be taken into account in the manner provided in section 28-6005.
H. The director shall adopt temporary and permanent rules for administering the tax imposed by this article and specifying the forms of the return and of the certification provided for in sections 28-6003 and 28-6004. The temporary and permanent rules shall prescribe the forms for and manner in which refunds may be claimed and refund claims assigned pursuant to subsection F of this section, shall specify the circumstances in which fuel may be excluded from the quantity of fuel used to measure the tax pursuant to title 28, chapter 16, article 6, and shall prescribe the forms for and manner which the certification provided in title 28, chapter 16, article 6 shall be made.
I. Title 41, chapter 6 shall not apply to the temporary rules adopted pursuant to this section. The temporary rules shall be filed with the secretary of state and shall be effective for a period of one hundred eighty days after the date of filing with the secretary of state. The temporary rules may be renewed twice in the same manner as they were adopted, may be amended at the time or times they are renewed, and shall be effective for a period of one hundred eighty days after the date the renewed temporary rules are filed with the secretary of state.
J. The permanent rules adopted pursuant to this section shall be adopted as provided in title 41, chapter 6.
