45 C.F.R. § 617.10 – Mediation.

(a) NSF will refer to the Federal Mediation and Conciliation Service all complaints that fall within the jurisdiction of this part and contain all information necessary for further processing.
(b) Both the complainant and the recipient shall participate in the mediation process to the extent necessary to reach an agreement or for a mediator to make an informed judgement that an agreement is not possible. NSF will take no further administrative action on any complaint if the complainant refuses to participate in the mediation process.
(c) If the complainant and the recipient reach an agreement, the mediator shall prepare a written statement of the agreement and have the complainant and recipient sign it. The mediator shall send a copy of the agreement to NSF. NSF shall take no further action on the complaint unless the complainant or the recipient fails to comply with the agreement, in which case the other party may request that the complaint be reopened.
(d) The mediator shall protect the confidentiality of all information obtained in the course of the mediation process. No mediator shall testify in any adjudicative proceeding, produce any document, or otherwise disclose any information obtained in the course of the mediation process without prior approval of the head of the Federal Mediation and Conciliation Service.
(e) NSF will use the mediation process for a maximum of 60 days after receiving a complaint. Mediation ends if:
1. (1) 60 days elapse from the time NSF receives a sufficient complaint: or
2. (2) Before the end of the 60 day period, an agreement is reached; or
3. (3) Before the end of the 60 day period, the mediator determines that an agreement cannot be reached.
(f) The mediator shall return unresolved complaints to NSF.
