(i) Service on the other party of a document required to be served on another party may be made by mail or by hand delivery, or, if agreed upon by the parties, by use of the OES or by any other means agreed to by the parties. A party who agrees to receive a document filed by another party by any means other than service by mail or hand-delivery may limit that agreement to one or more particular documents.

(b) All mailed written submissions referred to in this subpart shall be mailed by certified mail, return receipt requested.
(c) Determination of filing, receipt, or submission dates is based on the date of hand-delivery, the date of receipt recorded by the U.S. Postal Service, the date a document sent electronically by using the OES is recorded as received as indicated in the confirmation of receipt email for E-filing, or for other means, the date on which the delivery is recorded in the medium used for delivery.
