(b)  Notwithstanding any situation referred to in subsection (a), whenever the director or any of his or her duly authorized agents determines that an emergency situation exists which poses an imminent threat to public health or safety, he or she may issue an order mandating the immediate closure of the facility. The owner or manager of the facility shall be afforded an opportunity to be heard within ten (10) days of the order to show cause why the facility should be allowed to reopen.

(c)  The director may obtain relief in a court of equity when that relief shall be necessary in the proper performance of his or her duty under this chapter.
