(2) A copy of the order certified under the seal of the commission shall be served upon the person or corporation against whom it runs, or his or her or its attorney. Notice thereof shall be given to the other parties to the proceedings or their attorneys.
(3) The order shall take effect and become operative immediately upon the service thereof, unless otherwise provided, and shall continue in force either for a period which may be designated therein or until changed or revoked by the commission, or vacated upon review.
(4) If an order cannot, in the judgment of the commission, be complied with within the time fixed by the commission, the commission may grant and prescribe such additional time as in its judgment is reasonably necessary to comply with the order and may, on application and for good cause shown, extend the time for compliance fixed in the order.
