  2.  A certified copy of the determination so made shall be filed immediately with the secretary of state and with the department in Jefferson City.  Copies shall be supplied by the department to all persons requesting them within ten days after the filing.

  3.  At any time within thirty days after the certified copies of the determinations have been filed with the secretary of state and the department, any person who is affected thereby may object in writing to the determination or the part thereof that he deems objectionable by filing a written notice with the department, stating the specific grounds of the objection.
