(d) Assignment of non-staff hearing officers.
Individuals who are designated as eligible to serve as hearing officers may be assigned by the commissioner to hear proceedings in accordance with the needs of ORPTS.

A hearing officer's prior findings shall not be considered in making assignments.
(e) Hearing officers shall be compensated as provided in a schedule promulgated by the department.
(f) Communication with hearing officers.
No agency officer or employee, including a staff attorney assigned to a proceeding, or respondent in any proceeding, shall have any ex parte contact with a hearing officer regarding substantive issues, except contacts relating to nonsubstantive matters, such as arrangements for assignments, hearing officer contracts and the timing of the submission of hearing officer reports.
(g) A party may request the recusal of the hearing officer assigned to a proceeding by making a motion in writing, no fewer than 10 days prior to the hearing, to that hearing officer setting forth the reasons for the request. If the request is granted, the hearing officer shall set forth his decision in writing and submit a copy of that decision to all parties and the commissioner. Where the request is denied, the hearing officer shall set forth the reasons for the denial in the report prepared pursuant to subdivision (c) of this section.
