(a) On receipt of a complaint or a violation of this chapter or a rule or order adopted under this chapter or on its own motion, the department must give the person responsible for the quarry or pit written notice of each alleged violation, including the applicable statutory reference, and rule or order so violated and its relation thereto, and the date, time, and place for a hearing.

(b) If, after notice and a hearing, the department determines that a violation has occurred, the department must make written findings of the actual or threatened violation and the required corrective work and shall prescribe by order a specific period, commensurate with the work to be done but not to exceed 90 days from the date of the order, during which the corrective work must be done, unless an extension of time for good cause shown by the person responsible is granted by the department.

(c) If the responsible party fails to perform corrective work required by the department under Subsection (b) of this section within 120 days after notice is given to the responsible party, the department may contract for the corrective work to be done at reasonable, customary, and ordinary costs applicable in the industry. Such costs shall be submitted within 30 days of the date the work is finished, and the responsible party shall have 60 days to pay the costs or appeal the decision. In the event the responsible party fails to pay the costs as presented or fails timely to contest or appeal the costs as presented by the department, the department shall have the right to impose such fine or injunction as is warranted, consistent with the provisions of Section 133.082 et seq.
