If an approved license application is not used within 1 year after the date of approval, the approval is void unless the applicant files a written application with the Board for an extension. The Board may approve or deny an extension. The Board shall provide written notice to the applicant at the time of application that the approval is void if the license is not in use within 1 year after the date of approval.
