Failure to respond to administrative citation constitutes an admission of liability. Any person cited under an administrative citation is conclusively considered to have admitted liability for the violation cited and responsibility for abating the violation if, after thirty (30) days of service of the violation, the person: fails to pay the prescribed prepayable fine and abate the violation; or fails to request a hearing on the violation; or fails to appear on the designated hearing date, if the party has requested a hearing. Order of an Administrative Hearing Officer, default penalty. Under any of the circumstances described in subsection (a) of this section, an Administrative Hearing Officer may: render a default decision and order against the Respondent; and impose a civil penalty, after consideration of certain factors, which may include, the nature and severity of the underlying violation, history of past violations, mitigating or aggravating circumstances, that is: no less than the amount of the prepayable fine specified for the violation in question; and a maximum of: one thousand dollars ($1,000); or three times the prepayable fine specified for the violation in question. Notice of default order. Before an order based on a default becomes final, an Administrative Hearing Officer shall notify the Respondent, by first-class mail, of: the default decision and order; the amount of all penalties imposed; and the right of the Respondent, within thirty (30) days of the notice, to avoid a final judgment and collection proceedings by requesting that the default be vacated for good cause shown.
