Under the Dry Pea and Lentil Resources Act, no dry peas and lentils shall be subject to the tax more than once.

(2) After July 1, 2023, the commission may, whenever it determines that the excise tax levied by this section is yielding more or less than is required to carry out the intent and purposes of the Dry Pea and Lentil Resources Act, reduce or increase such levy for such period as it deems justifiable, but not less than one year, and such levy shall not be less than one percent of net market value and not exceed two percent of the net market value. Any adjustment to the levy shall be by rule and regulation adopted and promulgated by the commission.
