When a shipper files a formal complaint that a railroad's rate is too high, the Surface Transportation Board (Board) must determine whether the challenged rate is reasonable. To present its case using the Board's procedures for small cases, the complaining shipper needs to obtain from the Board confidential information that the Board collects regarding the rates that the defendant railroad charges other shippers for similar shipments. Pursuant to the notice of proposed rulemaking published in the Federal Register on October 27, 2010, the Board is formalizing its rules with respect to the Three-Benchmark methodology for adjudicating simplified rate case complaints, making the most recent four years of this confidential information available to parties and permitting the parties to use any combination of the four years of confidential information when presenting their cases.
