The Environmental Protection AgencyÌýMonday released the proposed 2011 percentage standards for its Renewable Fuel Standard.

The standard serves as a guide for the volumes of renewable fuel that fuel refiners, importers and blenders must ensure is used in transportation fuel, EPA said.

The proposed volumes are:

• Biomass-based diesel: 0.80 billion gallons; 0.68%

• Advanced biofuels: 1.35 billion gallons; 0.77%

• Cellulosic biofuels: 5 – 17.1 million gallons; 0.004% – 0.015%

• Total renewable fuels: 13.95 billion gallons; 7.95%

Public comments for the proposed volumes are due to the EPA 30 days after the proposed standards were released.
