For the same period, the Department of Energy’s retail on-highway diesel prices all types index monthly average, which is being used to determine the Intermodal Fuel Charge, was $3.096. Therefore, the Intermodal Fuel Percentage will be increased from 23% to 24.5%, effective July 1, 2018. The requirements and index history are available here.
The next review is set for June 2018 after which an appropriate adjustment will be made if necessary.
