Mo. Rev. Stat. § 324.733
The permit may be voided if any conditions of the permit are violated. Upon any violation, the permit must be surrendered and a new permit obtained before proceeding. Misrepresentation of information on an application to obtain a license, fraudulently obtaining a permit, alteration of a permit, or unauthorized use of a permit will render the permit void.
