The Board amends its regulations to expedite the resolution of rail rate challenges considered under the stand-alone cost (SAC) methodology. The revisions institute a requirement for mandatory, non- binding post-complaint mediation between the shipper and railroad under Board auspices, and establish expedited processes, using Board staff, for resolving discovery and evidentiary disputes. The Board also requests comments on the following discovery-related issues: developing a list of standard information that should be routinely made available in discovery; limiting the number of discovery requests available to the parties; limiting the number of years of data for which discovery responses would be required, and establishing a cut-off date for updating discovery responses; and cost-sharing for production of discovery responses.
