The Board shall send a written communication by first-class mail to the last address furnished to the Board by the applicant or licensee. It is the responsibility of an applicant or licensee to notify the Board in writing if there has been a change in an applicant’s or licensee’s address. Failure to respond as required by this regulation may be considered by the Board to be a violation of Business Regulation Article, §9A-310(a)(1)(xii), Annotated Code of Maryland.
