VIII. FUEL COST ADJUSTMENTS

A. The Purchaser will base any diesel fuel price adjustment on a four-week or five-week average, rounded to the nearest one cent ($0.01), using the rounding procedures in the DOT Materials Manual located on the Purchaser’s website.

The Purchaser will use the Weekly Retail On-Highway Diesel Prices – All Types – Midwest as reported by the U.S. Department of Energy, Energy Information Administration (EIA). A four-week average will be used for months with four Mondays. A five-week average will be used for months with five Mondays.

The Operations Support Office of the SDDOT will review the amended contract price monthly during the last week of each month. Any revised contract price will be effective for deliveries made the following month through the Office of Procurement Management.

If diesel fuel prices increase or decrease by more than 10 percent from the base diesel price of $5.392 per gallon, as established from the EIA Midwest publication dated June 3, 2026, the contract price will be amended.

For purposes of this adjustment, fuel consumption is estimated to represent approximately 50 percent of the total transportation cost for delivered loads. The fuel cost adjustment will be calculated as follows:

1. The base product price for alternative chemical deicers and magnesium chloride is established at $0.40 per gallon.

2. Total transportation cost will be determined by subtracting $0.40 per gallon from the Supplier’s bid price for the applicable delivery location.

3. Fifty percent of the total transportation cost will be used as the calculated fuel cost component.

4. The fuel cost component will be adjusted according to the percentage increase or decrease in the EIA Midwest diesel price average when the change exceeds the 10 percent threshold.

Example: The bid price of magnesium chloride is $1.60/gal. Then the transportation cost would be ($1.60-$.40) or $1.20/gal. Then 50% of that amount or $.60/gal will be used for the calculated fuel cost.

The percentage applied to the calculated fuel cost would be the amount over 10% to the nearest 0.1%.

Example: The current four- or five-week average fuel price, rounded to the nearest hundredth of a dollar, is $4.30/gal, and the published price on June 3, 2025, was $3.439/gal. The total percentage increase in fuel price is $4.300 - $3.439 = $0.861/$3.439 or 25.04%. Therefore, the amount applied to the calculated fuel cost would be 25.04% - 10% or 15.04%.

Therefore, the cost increase applied to the contract price would be 15.04% times the calculated fuel cost.

Example: $.60 x 15.04% = $.090/gal, therefore, use $.090/gal increase. So, $1.60/gal plus $.090/gal for an amended contract price of $1.690/gal.

1. The same calculations would hold true if the cost of fuel were to fall more than 10% below the published price on June 3rd, 2025.

B. Split Loads: Any time a Purchase Order directs that a load be split between more than one delivery location, Supplier will charge no more than $100.00 as a drop fee charged to each location following the first delivery. Supplier will confirm any drop shipment fees in its order confirmation.
