If the director denies the issuance or renewal of a liquid waste transport permit or suspends or revokes a liquid waste transport permit, the director shall send to the applicant or permit holder, by certified mail, return receipt requested, written notice of the action and of the right to an appeal. The applicant or permit holder may appeal the decision of the director to the permit and license appeal board in accordance with Section 2-96 of this code. The filing of a request for an appeal hearing with the permit and license appeal board stays an action of the director revoking a permit until the permit and license appeal board makes a final decision.
