Except as otherwise provided in the Administrative Procedure Act, State Government Article, Title 10, Subtitle 2, Annotated Code of Maryland, or in this regulation, before the Department takes any final action to deny, suspend, or revoke a certificate or letter of compliance or enforce an order to abate a violation, the Department shall give the person against whom the action is contemplated an opportunity for a hearing. A person shall request a hearing, if a hearing is desired, by submitting to the Department a written request for a hearing. To preserve the right to a hearing, a person shall submit the written request within 10 calendar days of the receipt of the denial, suspension, or revocation notice or an order.
