210 ILCS 95/23
Whenever the Department finds that an emergency exists which requires immediate action to protect the public health or safety, it may, without notice or hearing, issue an order reciting the existence of such an emergency and then require that such action be taken as it may deem necessary to meet the emergency including the closing of the campground or recreational area or the suspension or revocation of the permit or license. Notwithstanding any other provision in this Act such order shall be effective immediately. The State's Attorney and Sheriff of the county in which the recreational area or campground is located shall enforce the closing order after receiving notice thereof. Any owner, operator or licensee affected by such an order is entitled, upon request, to a hearing as provided in Section 14 of this Act. When such conditions are abated, in the opinion of the Department, the Department may authorize reopening the recreational area or campground.
