Whiteriver Unified School District, #20 is in Navajo County serving our K-12 Community on the Sovereign Nation of the White Mountain Apache. This Project: Bulk Fuel Delivery for Whiteriver USD, will be funded by the district’s maintenance and operations funds as well as some Federal Funds. The gasoline will be unleaded 87-octane regular gasoline and shall conform to the most recent American Society for Testing and Materials (ASTM) Standard Specification #D4814 or the latest edition standard specifications for automotive gasoline for the State of Arizona and any ASTM revision thereafter. The anti knock index (RON + MON/2) must be in compliance with ASTM D4814 or latest edition as it relates to unleaded regular gasoline. The minimum anti-knock octane for reformulated unleaded regular gasoline shall be 87. Gasoline is subject to the rules, regulations and Clean Air Act waivers of the U.S. Environmental Protection Agency (EPA), and Arizona State Statutes which require the use of reformulated oxygenated gasoline and specify maximum vapor pressures for certain areas. All Diesel fuel shall be all purpose ULSD fuel oil intended for use in all types of diesel engines under all normal conditions of service. The diesel fuel shall comply with ASTM D-975, Grade No. 1-D S15—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 15 ppm sulfur (maximum) and higher volatility than that provided by Grade No. 2-D S15 fuel, with a cetane rating of 45. Cetane rating will be computed using the ASTM D-976 method. Using this standard, a required octane rating of 45 has a tolerance, but with this tolerance, it may not be lower than 40 cetane. The calculated cetane method will be used to determine cetane rating of fuel. Please refer to ASTM D976, latest edition, for test method to ensure cetane rating of 45 is being delivered. No cetane enriching additives are to be used. Only ultra low sulfur No. 2 diesel fuel with sulfur content of 0.0015% or less will be accepted. All Gasoline will meet all Arizona Department of Environmental Quality (ADEQ) requirements for fuel type and locality.
