c. Develop and implement a procedure for paying such interest in not more than seven days from the payment date on those proper invoices for which interest is due and for which the director of the budget does not issue a certificate or certificates increasing, transferring, or interchanging funds so that an interest payment can be made pusuant to this article. The comptroller shall also develop and implement a procedure for paying such interest in not more than fourteen days from the payment date on those proper invoices for which interest is due and for which the director of the budget does issue a certificate or certificates increasing, transferring, or interchanging funds so that an interest payment can be made pursuant to this article.

d. Develop and implement a procedure by which every state agency will notify contractors promptly and directly whenever the state comptroller rejects a voucher and returns it to the state agency due to an error or omission in the voucher by the contractor.

2. Nothing contained in this section shall be deemed to preclude the comptroller from subsequently promulgating, developing, or amending rules and regulations or procedures pursuant to, and consistent with, this article.

3. The state comptroller shall submit a detailed special report to the governor and the legislature which shall include the number and amounts of interest payments made for each state agency, the number of interest chargeable days and the number of days taken to process the contract payment, the extent to which those delays occurred because the state agency took longer than allotted pursuant to the provisions of this article to process the affected invoices and the extent to which those delays occurred because the department of audit and control took longer than allotted pursuant to the provisions of this article to process the related vouchers, and a summary of the principal reasons that such late payments occurred. The report shall be delivered to the governor and legislature within sixty calendar days after the conclusion of each fiscal year.
