(a) CMRS providers are eligible for reimbursement from the 911 Fund as set forth in subsections (b) and (c) of Section 11-98-5.2. To obtain reimbursement, a CMRS provider shall comply with all of the following:
(1) Invoices shall be sworn.
(2) All costs and expenses must be commercially reasonable.
(3) All invoices for reimbursement shall be directly related to compliance with the requirements of enhanced 911 service.
(4) The board shall adopt rules providing for prior approval of any expenditures for which the CMRS provider intends to seek reimbursement in excess of a threshold amount.
(5) All invoices shall be supported by such reasonable supporting documents as required by the board and shall be subject to audit.
(b) If the total amount of invoices submitted to the 911 Board and approved for payment in a month exceeds the amount available from the 911 Fund for reimbursements to CMRS providers, the amount payable to each CMRS provider shall be reduced proportionately so that the amount paid does not exceed the amount available for payment. The balance of the payment is deferred to the following month. A deferred payment accrues interest at a rate equal to the rate earned by the 911 Fund until it is paid.
