The board may suspend or revoke a permit if it appears that the permittee no longer has the qualifications necessary for the issuance of an original permit or has violated any provision of this chapter, or any of the rules adopted under it.

The board may revise the conditions and limits of a permit if:

1.    The permittee is given notice and a reasonable opportunity for a hearing, to be held in accordance with chapter 28-32.

2.    It appears to the board that a modification of the conditions and limits of a permit is necessary to protect the public’s health, safety, welfare, or the environment.

If it appears to the board that an emergency situation exists or is impending which could endanger the public’s health, safety, welfare, or the environment, the board may, without prior notice or hearing, immediately modify the conditions or limits of a permit, or order temporary suspension of a permit. The issuance of such an order shall include notice of a hearing to be held within ten days thereafter on the question of permanently modifying the conditions and limits or continuing the suspension of the permit. Failure to comply with an order temporarily suspending an operation or modifying the conditions and limits of a permit shall be grounds for immediate revocation of the license and permit of the person controlling or engaged in the operation.
