The amount charged for fees imposed under this chapter shall approximate and reasonably reflect costs necessary to defray the expenses of the Board, as well as the proportional expenses incurred by the Division in its service on behalf of the Board. There shall be a separate fee charged for each service or activity, but no fee shall be charged for a purpose not specified in this chapter. The application fee shall not be combined with any other fee or charge. At the beginning of each biennium year, the Division, or another state agency acting on its behalf, shall compute the appropriate fee for each separate service or activity.
