Service of any decision, order, subpoena, notice, or other written process may be made by, for, or on behalf of the Board by personal service or by mailing a copy by certified mail. The Board shall make service by certified mail to the address of record on file with the Board. Service upon an attorney who has appeared on behalf of a party constitutes service upon the party. If service is by certified mail, service is complete upon deposit in the United States mail.
