(a) Unless a negotiated service agreement reached under AS 37.10.052(b) or (c) provides otherwise, a resource agency charging a fee for providing a designated regulatory service other than a standard designated regulatory service for which a fixed fee has been established under AS 37.10.052 (a) shall, on a monthly basis, provide the person who will be billed for the service with an invoice for services performed during that month. The invoice must be reasonably convenient to the reader, and reasonably susceptible to audit. The invoice must set out, in time increments of not greater than one-quarter hour for each employee, and separately for each expenditure, the purpose of the time or expenditure in sufficient detail to permit a reasonable person to determine whether the time or cost was an actual and reasonable direct cost.
(b) If a person believes that an invoice rendered under (a) of this section exceeds the actual and reasonable direct cost of providing the designated regulatory service, the person may, within 30 days after receiving the invoice, request that the resource agency review the invoice. The resource agency shall review the invoice under the standards of this section and issue its final decision on the invoice within 30 days of receipt of a request for review.
