Blend Wall

There is a fundamental flaw in the system designed to ensure compliance with the Renewable Fuel Standard (RFS): The assumption that refiners would not blend ethanol into their fuel were it not for the policy and its threat of crippling costs being imposed on obligated parties who do not blend.

Since the Renewable Fuel Standard (RFS) was enacted, the Environmental Protection Agency (EPA) has had the difficult responsibility of implementing a broken and unworkable biofuel blending program.
