The fuel surcharge is related directly to the national diesel fuel prices as reported by the Energy Information Administration of the U.S. Department of Energy (EIA/DOE) in its Retail On-Highway Diesel Prices Index for the Central Atlantic Region. This index is available to the public and is widely recognized in trucking and transportation industries. Learn more about the index. Trash Tech will update the fuel surcharge monthly and base the surcharge amount on the corresponding diesel fuel price per gallon for the preceding month according to EIA/DOE prices.
