§ 10707. Determination of market dominance in rail rate proceedings
(a)
In this section, “market dominance” means an absence of effective competition from other rail carriers or modes of transportation for the transportation to which a rate applies.
(b)
When a rate for transportation by a rail carrier providing transportation subject to the jurisdiction of the Board under this part is challenged as being unreasonably high, the Board shall determine whether the rail carrier proposing the rate has market dominance over the transportation to which the rate applies. The Board may make that determination on its own initiative or on complaint. A finding by the Board that the rail carrier does not have market dominance is determinative in a proceeding under this part related to that rate or transportation unless changed or set aside by the Board or set aside by a court of competent jurisdiction.
(c)
When the Board finds in any proceeding that a rail carrier proposing or defending a rate for transportation has market dominance over the transportation to which the rate applies, it may then determine that rate to be unreasonable if it exceeds a reasonable maximum for that transportation. However, a finding of market dominance does not establish a presumption that the proposed rate exceeds a reasonable maximum.
(d)
(1)
(A)
In making a determination under this section, the Board shall find that the rail carrier establishing the challenged rate does not have market dominance over the transportation to which the rate applies if such rail carrier proves that the rate charged results in a revenue-variable cost percentage for such transportation that is less than 180 percent.
(B)
For purposes of this section, variable costs for a rail carrier shall be determined only by using such carrier’s unadjusted costs, calculated using the Uniform Rail Costing System cost finding methodology (or an alternative methodology adopted by the Board in lieu thereof) and indexed quarterly to account for current wage and price levels in the region in which the carrier operates, with adjustments specified by the Board. A rail carrier may meet its burden of proof under this subsection by establishing its variable costs in accordance with this paragraph, but a shipper may rebut that showing by evidence of such type, and in accordance with such burden of proof, as the Board shall prescribe.
