mussels. If dreissenid mussels are detected or may be present, the
director or his or her designee may order the affected waters or
facilities closed to conveyances or otherwise restrict access to the
affected waters or facilities, and shall order that conveyances
removed from, or introduced to, the affected waters or facilities be
