If an applicant or licensee receives from the Commission a written communication requesting a response, the applicant or licensee shall respond within 30 days of the date of the mailing. The Commission shall send a written communication by first-class mail to the last business address furnished to the Commission by the applicant or licensee. It is a responsibility of an applicant or licensee to notify the Commission in writing if there has been a change in the applicant’s or licensee’s address. Failure to respond as required by this regulation may be considered by the Commission to be a violation of Business Regulation Article, §§8-311(a)(11)—(13) and 8-616, Annotated Code of Maryland.
