If in the judgment of the board the aforesaid proposal is reasonable and meets the requirements of this section, the board shall approve the proposal; if not, it shall notify the operator of the reasons for its disapproval in writing. The operator shall thereupon submit an amended proposal. If the board disapproves of the amended proposal, the operator may appeal the action to the circuit environmental court in accordance with section 181-8; otherwise, the operator shall submit another amended proposal until approval is obtained. Upon approval being obtained, or the issuance of an order in the event of an appeal, the operator shall commence work under the reclamation proposal and shall prosecute the work required thereunder with reasonable diligence and effect reclamation within a period of two years next following the approval or issuance of the order, unless the time is extended by the board. The operator shall notify the board upon completion of reclamation, whereupon an inspection shall be made of the pit by the board and a determination made of the satisfactory performance by the operator of the proposal. In the event that the proposal and this chapter has been complied with, the board shall take such action as is required under sections 181-5 and 181-7. In the event that the performance shall not be satisfactory, the board shall serve upon the operator written directions for additional performance, and unless an appeal is taken therefrom under section 181-8, the operator shall forthwith comply with the directions.
