Biofuel Blend Dispenser Labeling Requirement
Pumps dispensing ethanol must label the percentage of ethanol present in the fuel. Ethanol pumps distributing between 1% and 10% must include a label stating that the fuel “contains up to 10% ethanol” and those distributing blends greater than 10% must be labeled with the capital letter E, followed by the numerical value volume of ethanol and the word “ethanol.” (Code of Washington 19.112.020, and Washington Administrative Code 16-662-115)

Biofuel Quality Program
The Washington State Department of Agriculture (WSDA) Biofuels Quality Program tests and assesses biofuel quality and quantity to resolve any quality issues before the product reaches the consumer. WSDA samples biofuel throughout the state, monitors and tracks the quality of biofuel, and works with producers and manufacturers to help supply the highest biofuel quality fuel available to consumers. The goal of the program is to create equity in the biofuel marketplace for refiners, suppliers, distributors, and retailers, and protect consumers. For more information, see the WSDA Biofuels Quality Program website. (Revised Code of Washington 19.112.005 to 119.112.080)

Alternative Fuel Use Requirement
All state agencies must, to the extent practicable, use 100% biofuels or electricity to operate all publicly owned vehicles. Agencies may substitute natural gas or propane for electricity or biofuel if the Washington State Department of Commerce determines that electricity and biofuel are not reasonably available. Transit agencies using compressed natural gas (CNG) and engine retrofits that would void vehicle warranties are exempt from this requirement. To allow the motor vehicle fuel needs of state and local government to be satisfied by Washington-produced biofuels, the Washington Department of Enterprise Services and local governments may contract in advance and execute contracts with public or private producers and suppliers for the purchase of appropriate biofuels.
(Washington Administrative Code 194-28 and Revised Code of Washington43.19.647 and 43.19.648)

Renewable Fuel Standard
At least 2% of the total gasoline sold in the state must be denatured ethanol. The ethanol requirement increases if the Washington Department of Ecology determines that this increase will not jeopardize continued attainment of federal Clean Air Act standards, and WSDA determines that the state can economically support the production of higher ethanol blends. (Revised Code of Washington 19.112.010 and 19.112.110 through 19.112.180)
