Sec.  27.1172   Dispute Resolution Under the Cost-Sharing Plan.

   (a) Disputes arising out of the cost-sharing plan, such as disputes over the
   amount of reimbursement required, must be brought, in the first instance, to
   the clearinghouse for resolution. To the extent that disputes cannot be
   resolved by the clearinghouse, parties are encouraged to use expedited
   Alternative Dispute Resolution (ADR) procedures, such as binding
   arbitration, mediation, or other ADR techniques.

   (b) Evidentiary requirement. Parties of interest contesting the
   clearinghouse's determination of specific cost-sharing obligations must
   provide evidentiary support to demonstrate that their calculation is
   reasonable and made in good faith. Specifically, these parties are expected
   to exercise due diligence to obtain the information necessary to prepare an
   independent estimate of the relocation costs in question and to file the
   independent estimate and supporting documentation with the clearinghouse.
