I'm not sure that ethanol mandates are a good idea. It's not clear that the entire life-cycle costs (in terms of CO2 emissions) of adding ethanol is better than the gasoline that it displaces, see [1]. This would mean that the mandates and incentives would be be better spent on other ways to reduce emissions.
