A. The Oklahoma Alternative Fuels Conversion Fund shall be reimbursed by a surcharge on alternative fuels sold within the state under the provisions of the Oklahoma Alternative Fuels Conversion Act.

B. A reimbursement account shall be established in the name of each recipient of reimbursement for vehicle conversion and/or fill station installation pursuant to the provisions of Section 603 of this title.¹ The initial amount of each recipient's account shall be the amount of the reimbursement received by that recipient. A recipient's account shall be increased by the amount of any subsequent reimbursement received by that recipient; a recipient's account shall be reduced by the amount of all surcharges on alternative fuels paid by that recipient.

C. A surcharge in an amount equivalent to the per gallon fuel cost savings in utilizing alternative fuels is hereby levied on sales of alternative fuels to recipients of reimbursement for vehicle conversion and/or fill station installation pursuant to the provisions of Section 603 of this title. Initially, the amount of the surcharge shall be based upon monthly fuel savings as determined in the manner prescribed in subsection A of Section 603 of this title. Such amount shall be adjusted periodically, by the Oklahoma Tax Commission, to reflect any change in the amount of fuel savings actually received by the recipient. The surcharge shall not be levied on sales of alternative fuels for any other purposes. The surcharge shall continue on sales to each such recipient for so long as that recipient maintains a reimbursement account. When the reimbursement account for a recipient is reduced to zero, the surcharge levied by this section shall terminate until such time as a reimbursement account may be re-established for that recipient.

D. The surcharge levied by this section shall be collected by the Oklahoma Tax Commission and apportioned monthly to the Oklahoma Alternative Fuels Conversion Fund.

E. The surcharge levied by this section shall be suspended whenever the price of the alternative fuel used by the recipient is equal to or greater than the price of the original fuel displaced by the alternative fuel which may be purchased by such recipient. Provided, such surcharge shall be reinstated whenever the price of the alternative fuel used by the recipient becomes less than the price of the original fuel displaced by the alternative fuel which may be purchased by such recipient.

F. The Oklahoma Tax Commission shall adopt rules and regulations relating to the payment and collection of the surcharge levied by this section.
