Kansas Guidelines For Blending Flex Fuels Pilot Program

10/08/08
The blending of fuels with ethanol percentages between 10 percent and 85 percent will be permitted on a trial basis until January 1, 2009. During this period the Kansas Department of Agriculture will monitor the equipment used to dispense the ethanol blends to ascertain that the equipment is suitable and is capable of producing an accurate measurement. Since there are no ASTM standards for evaluating the quality of the product, we will take fuel samples to ascertain that the correct blend ratios are being dispensed and follow the development of standards. Provided that no negative trends are observed during the trial period and fuel standards have been developed or work continues on developing them, we will consider extending the evaluation period. During this time the following requirements must be met:

  1. Suitability of equipment.
    • Device must have NTEP certificate and comply with the applicable provisions of it including flow rates.
    • Blending and dispensing system must be compatible for flex fuels.
    • Dispensing and associated equipment must comply with all applicable requirements of NIST Handbook 44
  2. Labeling of dispenser and Storage Tanks.
    • E-10 and unleaded 87 must be labeled with octane rating (yellow background).
    • Flex fuels E20-, E30, E-85 are prohibited from displaying an octane rating.
    • Flex fuel blends must be labeled with “orange” labels and warning labels providing the following or similar statement: “Warning Contains 20% Ethanol. For Use in Flexible Fuel Vehicles (FFV) only.”
    • Storage tanks must be properly identified as to the fuel contained in the tank. Although under current rules and regulations, color coding is permissible, it is highly recommended that storage tanks be permanently identified to minimize the risk of putting E-95 in the wrong storage tank.
  3. Proper dispensing of fuels.
    • E-95 should only be used as a blend stock for E-10 or greater ethanol blend. It should
    • not be offered as a fuel itself. E-10 may be used as a blend stock for E-20 and greater blends.
    • Flexible Fuel that is greater than 10% ethanol should be dispensed from a hose separate from the E10 or unleaded unless it can be demonstrated that the proper E10 blend can be delivered after a higher blend has been delivered.
    • All dispensers must be accurate and the blend ratios correct.
  4. Ethanol Issues.
    • Flex fuel dispensers must be equipped with an ethanol rated filter (10 micron).
    • Storage tanks and lines used to store E-95 must be cleaned prior to start up.
  5. Fuel Quality Standards.
    • Unleaded 87 octane and E-10 must meet ASTM standards, D-4814.
    • E-85 must meet ASTM standards, D-5798.
    • E-95 must meet ASTM D-4806.
    • E-20, E30 or other blends will be monitored for percent of blends.
  6. Inspections
    • An initial inspection, including fuel quality will be conducted prior to the station opening for business.
    • Periodic inspections will be conducted to monitor the equipment’s performance and fuel quality.
