Specifications include, but are not limited to: . Supplier shall warrant that all fuels sold to the County shall be of high quality, with no more than a 10% ethanol additive as federally mandated, and suitable for the intended use. Supplier shall agree to provide Union County with a continuous supply of Regular Unleaded Gasoline (Octane-87) and diesel fuels #1 (or 1-D) or #2 (or 2-D) depending on the season. A winter additive is acceptable. We have no specific blend ratio, we just need fuel that will burn in cold weather. B. Supplier, at its own expense, shall assign a Purchasing-card, Credit-card, or Account card for each bulk tank location. The County employee, assigned as tank manager, may then use the card to order fuel without a Purchase Order being issued, and the appropriate amount will be charged to Union's account.
