(2) Within 45 days after the completion of the plugging and decommissioning of any geothermal well, the operator of the well shall make a written report of all work done. Within 45 days after the receipt of the report, the department shall furnish the operator with a written final approval of the plugging and decommissioning or a written disapproval setting forth the conditions upon which the disapproval is based.

(3) Failure to plug and decommission in accordance with the approved method, failure to submit to the department any notice or report required by this chapter or failure to furnish the department with any required information shall constitute sufficient grounds for disapproval of the plugging and decommissioning and shall constitute unlawful abandonment of the well.
