All subpoenas issued by the Director or hearing officer may be served as provided for in civil actions. The fees of witnesses for attendance and travel shall be the same as the fees for witnesses before the circuit court and shall be paid by the party to such proceeding at whose request the subpoena is issued. If such subpoena is issued at the request of the Department or by a person proceeding in forma pauperis the witness fee shall be paid by the Department as an administrative expense.
