(a) The employee shall be advised in the notification that a hearing may be requested by filing a written petition within 15 calendar days of receipt of the notification, addressed to the chief of the paying agency's accounting or finance office.
(b) The petition shall state the grounds upon which the employee disputes the proposed collection of the alleged debt. The petition shall identify and explain with reasonable specificity the facts, evidence which, and witnesses who the employee believes support his or her position.
(c) The timely filing of a petition for hearing shall stay any further collection proceedings. A decision by the administrative law judge or other hearing official (see § 92.5(j)) will be issued at the earliest practical date, but no later than 60 days after the filing of a petition for hearing, unless a delay is granted at the request of the employee.
