Sec. 2   RCW 19.112.120 and 2006 c 338 s 3 are each amended to read as follows:
     (1) By December 1, 2008, motor vehicle fuel licensees under chapter 82.36 RCW, other than motor vehicle fuel distributors, shall provide evidence to the department of licensing that at least two percent of total gasoline sold in Washington, measured on a quarterly basis, is denatured ethanol.
     (2) If the director of ecology determines that ethanol content greater than two percent of the total gasoline sold in Washington will not jeopardize continued attainment of the federal clean air act's national ambient air quality standard for ozone pollution in Washington and the director of agriculture determines and publishes this determination in the Washington State Register that sufficient raw materials are available within Washington to support economical production of ethanol at higher levels, the director of agriculture may require by rule that licensees provide evidence to the department of licensing that denatured ethanol comprises between two percent and at least ten percent of total gasoline sold in Washington, measured on a quarterly basis.
     (3) The requirements of subsections (1) and (2) of this section shall take effect no sooner than one hundred eighty days after the determination has been published in the Washington State Register.
     (4) The director and the director of licensing shall each adopt rules, in coordination with each other, for enforcing and carrying out the purposes of this section.
     (5) Nothing in this section is intended to prohibit the production, sale, or use of motor fuel for use in federally designated flexibly fueled vehicles capable of using ((up to eighty-five percent ethanol fuel blends)) E85 motor fuel. Nothing in this section is intended to limit the use of high octane gasoline not blended with ethanol for use in aircraft.

Sec. 3   RCW 82.04.4334 and 2003 c 63 s 1 are each amended to read as follows:
     (1) In computing tax there may be deducted from the measure of tax amounts received from the retail sale, or for the distribution, of:
     (a) Biodiesel fuel; or
     (b) ((Alcohol fuel, if the alcohol fuel is at least eighty-five percent of the volume of the fuel being sold or distributed)) E85 motor fuel.
     (2) For the purposes of this section and RCW 82.08.955 and 82.12.955, the following definitions apply:
     (a) "Biodiesel fuel" means a mono alkyl ester of long chain fatty acids derived from vegetable oils or animal fats for use in compression-ignition engines and that meets the requirements of the American society of testing and materials specification D 6751 in effect as of January 1, 2003.
     (b) (("Alcohol fuel" means any alcohol made from a product other than petroleum or natural gas, which is used alone or in combination with gasoline or other petroleum products for use as a fuel for motor vehicles, farm implements and machines, or implements of husbandry.)) "E85 motor fuel" means an alternative fuel that is a blend of ethanol and hydrocarbon of which the ethanol portion is nominally seventy-five to eighty-five percent denatured fuel ethanol by volume that complies with the most recent version of American society of testing and materials specification D 5798.
     (c) "Distribution" means any of the actions specified in RCW 82.36.020(2).
