The materiel division shall keep an accurate record of the postage used by each state officer, department, commission, board, bureau, court, or other agency and charge such state officer, department, commission, board, bureau, court, or other agency with the exact amount of postage so used plus administrative and operational costs. Administrative and operational costs shall be charged as a percentage of the amount charged for postage. Such charge shall, as nearly as may be practical, reflect the actual administrative and operational costs of the central mailing room and its related activities. The division shall submit electronically an annual report to the Appropriations Committee of the Legislature of the percentage charge. Rates planned for the coming fiscal year shall be included in the instructions for completion of budget request forms as annually prepared by the Department of Administrative Services' budget division. If rate revisions are required during the fiscal year to reflect changes in the administrative and operational costs, these revisions shall be announced to each state officer, department, commission, board, bureau, court, or other agency at least thirty days prior to their use.
