If any notice of appeal is found by the board to be defective or insufficient, the board may require the party filing said notice of appeal to correct, clarify or amend the same to conform to the requirements of the statute and the board's rules. The board may refuse to schedule any conference or hearing thereon until compliance with such requirement, or may issue an order providing for the denial or dismissal of such appeal upon failure to comply within a specified time.
