All documents submitted by a party and intended to be part of the agency record for decision must be served upon the representatives of each party of record concurrently with filing with the presiding officer and any other person designated by the agency to receive filings in the case. The presiding officer may direct that some or all of these documents be served on interested or affected persons who are not parties. The presiding officer may also direct the means of service the parties are to use during a contested case proceeding.
