The initial order will become final unless, within thirty days of mailing of the initial order to the parties, the commission determines that the initial order should be reviewed or a party to the proceedings files a petition for review of the initial order. A petition for review shall set forth in detail the grounds for review and the party filing the petition shall be deemed to have waived all objections or claims of irregularities not specifically set forth therein. The initial order will be considered by the commission at the next succeeding regularly scheduled meeting of the commission at which review can practicably be conducted. The commission shall thereafter enter a final order.
