If the director denies the issuance or renewal of a license, suspends or revokes a license, or orders the cessation of any part of the business operation conducted under the license, the aggrieved party may appeal the decision of the director to a permit and license appeal board in accordance with Section 2-96 of this code. The filing of an appeal stays the action of the director in suspending or revoking a license or any part of the business operation being conducted under the license until the permit and license appeal board makes a final decision unless the director determines that operation of the facility or business in violation of the suspension or revocation constitutes an imminent and serious threat to the public health or safety, in which case the director shall take or cause to be taken such action as is necessary to immediately enforce the suspension, revocation, or order.
