(3) Cases in which DoD is unable to receive payment requests or provide acceptance in electronic form;

(4) Cases in which the contractor has requested permission in writing to submit payment requests and receiving reports by nonelectronic means, and the contracting officer has provided instructions for a temporary alternative method of submission of payment requests and receiving reports in the contract administration data section of the contract or task or delivery order (e.g., section G, an addendum to FAR 52.212-4, or applicable clause); and
