1. 1. Except as provided in subsection B of this section, the person is subject to a civil penalty of one thousand dollars or ten dollars for each gallon of use fuel dispensed, whichever is greater, and shall pay to the department the difference between the amount of light class motor vehicle use fuel tax paid and the amount of the use class motor vehicle use fuel tax on the same number of gallons purchased.
2. 2. The department may not deny a refund requested by a vendor pursuant to section 28-5614 for that purchase.
3. 3. The department shall not impose any penalty, including a financial penalty of any kind, on a vendor for that purchase if the purchase was determined as a result of any inquiry, including any audit process.
