Like other transportation firms, Rumpke battles the rising cost of diesel fuel, petroleum based products and supply shipping costs related to escalating petroleum prices. Pricing adjustments became necessary to compensate for a portion of the higher costs. Due to the fluidity of the petroleum market, Rumpke adopted a flexible fuel surcharge structure that adjusts with the rise and fall of diesel prices. Rumpke’s fuel surcharge is calculated using prices reported by the Energy Information Administration of the U.S. Department of Energy (EIA/DOE). This standardized diesel fuel surcharge appears as a single line item on your invoice.

Calculation of the Fuel Surcharge
The fuel surcharge is related directly to the national diesel fuel prices as reported by EIA/DOE in its Retail On-Highway Diesel Prices Index for the Midwest Region. This index is available to the public and is widely recognized in trucking and transportation industries. Learn more about the index.

Rumpke updates its fuel surcharge monthly, and bases the surcharge amount on the corresponding diesel fuel price per gallon the last week of the preceding month according to EIA/DOE prices. For example, the diesel fuel price per gallon was $4.667 per gallon during the last week of June 2008; therefore the fuel component of the charge was 18.35 percent of your total invoice amount, excluding taxes. However, by the last week of November prices had changed significantly dropping to $2.624 per gallon, making the fuel component portion of customer bills 8.10 percent.
