Grassley: Same old story, biofuels under attack

Those of us from states that produce ethanol and biodiesel are used to the attacks. We always fight back, and producers continue to do their best to develop the next generation of clean biofuels. Consumers like biofuels. The idea of a homegrown product that reduces emissions harmful to the environment and brings the United States freedom from volatile oil-producing countries is appealing.The EPA should know this.
