The amendments are intended to clarify the process by which the costs of detention care are shared by state and county government. Specifically, the rule clarifies the distinction between pre- and post-disposition so that post-disposition will only include days in secure detention following disposition during which a child is awaiting residential placement. The amendments also modify the reporting and reconciliation provisions so that monthly reporting and reconciliation will take place. A per diem rate for detention care will be derived according to a specified formula, and the rate will be used to make monthly adjustments in actual utilization. Dates for reporting and reconciliation are adjusted, and definitions are amended to reflect these changes.
