The administrative procedure involved in the adopting of any rules or regulations or the issuance of any orders by the commission under the provisions of this chapter must be in accordance with the provisions of chapter 38-08 governing the procedure in the administration of the Oil and Gas Conservation Act; provided, however, that in the event an emergency is found to exist by the commission which in its judgment requires the making, revoking, changing, amending, modifying, altering, enlarging, renewal, or extension of a rule, regulation, or order without first having a hearing, such emergency rule, regulation, or order has the same validity as if a hearing with respect to the same had been held after due notice. The emergency rule, regulation, or order permitted by this section may remain in force no longer than fifteen days from its effective date, and in any event, it expires when the rule, regulation, or order made after due notice and hearing with respect to the subject matter of such emergency rule, regulation, or order becomes effective.
