Del. Code tit. 24, § 2908

The amount to be charged for each fee imposed under this chapter shall approximate and reasonably reflect all costs necessary to defray the expenses of the Commission, as well as the proportional expenses incurred by the Division in its services on behalf of the Commission. There shall be a separate fee charged for each service or activity, but no fee shall be charged for an activity 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 any other state agency acting in its behalf, shall compute for each separate service or activity, the appropriate fee for the coming year.
