The Surface Transportation Board is amending its regulations to require Class I railroads to report certain data concerning fuel costs and fuel surcharges billed. The data reported pursuant to this rule will provide an overall picture of the use of fuel surcharges and will permit the Board to monitor the fuel surcharge practices of Class I carriers. The new rule will be codified as 49 CFR 1243.3. The reporting form can be found in an Appendix to this section.
