Fuel Cost FUEL SURCHARGE INFORMATION In today's economy the prices of various energy products are constantly changing A variety of market factors from across the globe are impacting the supply and demand for these energy products, which ultimately has a substantial impact on fuel pricing, processing operations, and petrochemical products. In order to ensure our customers get the best value in service and price, Safety-Kleen has initiated a fuel surcharge indexing program. This method applies a surcharge on a per service stop basis, allowing our customers to benefit from Safety-Kleen's performance of multiple services at each stop. The U.S. surcharge will be adjusted based on the Monthly On-Highway Ultra-Low Sulfur Diesel Fuel Prices reported by the U.S. Department of Energy's (DOE) Energy Information Administration or Natural Resources Canada's (NRCan) Fuel Focus for our Canadian locations. Changes to the index-based surcharge go into effect the first Monday of each month based upon the prior month's average fuel cost. Click here to view the rate index table.
