Informal Review. On initially determining that an applicant or firm does not meet the standards set forth in Business Occupations and Professions Article, Title 13, Annotated Code of Maryland, or this chapter, the Secretary may: Notify the applicant to appear for an informal review of the application; Ask the applicant to produce additional documentation for the Secretary to consider; and If the applicant fails to appear, make a final determination to approve or deny the application for a license or certification based on the information available. Letter of Denial. On denial of the license or certification, the Secretary shall send, by certified mail, a letter advising the applicant of the reason for denial. The notification letter shall include the applicable statement of law or regulation on which the decision to deny the application is based. The letter shall advise the applicant that the applicant has 30 days from the date of the letter to send in a written appeal to the Licensing Division. An applicant shall keep the applicant's current address on file with the Licensing Division. An applicant who has moved without notification to the Licensing Division or has refused delivery of the denial letter is deemed to be duly served the notice of denial. If the applicant fails to submit a written appeal within 30 days, the applicant is deemed to have waived the applicant's rights to appeal and the proposed action becomes final.
