NEW: Operator Renewal Forms Available for Download
To locate a particular renewal form, the operator's expiration date and certificate number are required. Since the applications are database generated, all certificates that expire in the same month are printed in one report in order of certification numbers. Operators can find their certification number using the Active Operator Reports on this web page.
The TWO PAGE application can be downloaded and must be submitted with fee and proof of continuing education by mail or deposited into MDE's lock box at 1800 Washington Blvd (Baltimore 21230)- receipts cannot be issued. Board staff recommends submitting renewal applications at least 60 days prior to expiration date to avoid delays and late fees. Board staff will continue mailing renewal forms approximately 120 days prior to expiration.
