(a) When. Within 20 days of service of the notice, respondent shall file an answer as designated in the notice. In a civil money penalty proceeding, respondent shall also file a request for a hearing within 20 days of service of the notice.

(b) Content of answer. An answer must specifically respond to each paragraph or allegation of fact contained in the notice and must admit, deny, or state that the party lacks sufficient information to admit or deny each allegation of fact. A statement of lack of information has the effect of a denial. Denials must fairly meet the substance of each allegation of fact denied; general denials are not permitted. When a respondent denies part of an allegation, that part must be denied and the remainder specifically admitted. Any allegation of fact in the notice which is not denied in the answer must be deemed admitted for purposes of the proceeding. A respondent is not required to respond to the portion of a notice that constitutes the prayer for relief or proposed order. The answer must set forth affirmative defenses, if any, asserted by the respondent.

(c) Default—

(1) Effect of failure to answer. Failure of a respondent to file an answer required by this section within the time provided constitutes a waiver of his or her right to appear and contest the allegations in the notice. If no timely answer is filed, Enforcement Counsel may file a motion for entry of an order of default. Upon a finding that no good cause has been shown for the failure to file a timely answer, the administrative law judge shall file with the Comptroller a recommended decision containing the findings and the relief sought in the notice. Any final order issued by the Comptroller based upon a respondent's failure to answer is deemed to be an order issued upon consent.

(2) Effect of failure to request a hearing in civil money penalty proceedings. If respondent fails to request a hearing as required by law within the time provided, the notice of assessment constitutes a final and unappealable order.
