The Midwestern Governors Association is calling on the U.S. Environmental Protection Agency to uphold the Renewable Fuels Standard passed by Congress in December.

In a letter to EPA Administrator Stephen Johnson, the group said that granting a waiver would be contrary to the agency’s mission of protecting human health and the environment. The letter adds that blame placed on ethanol for higher food prices is misguided.

The Midwestern Governors Association includes the governors of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota and Wisconsin working together on issues of significance to the Midwest.
