A bi-partisan group of lawmakers is calling on the government to end its proposal to reduce the amount of ethanol and biodiesel that will be blended into the Nation’s fuel supply. Led by Democratic Congresswoman Cheri Bustos (IL-17) and Republican Congresswoman Kristi Noem (SD-AL), the group has sent a letter to the Environmental Protection Agency (EPA) over the agency’s proposal to reduce the renewable volume obligations (RVOs) under the Renewable Fuel Standard (RFS).

In a letter to EPA Administrator Gina McCarthy, the Members of Congress said that reducing the amount of renewable fuels in gasoline could hurt rural economies, jeopardize American jobs, raise prices at the pump and deter investment in biofuels and biofuel infrastructure. They asked that the EPA revise their proposal before the 60 day comment period ends on January 28th.

“We are writing to express our concern regarding the Environmental Protection Agency’s (EPA) proposed rule for the 2014 renewable volume obligations (RVOs) under the Renewable Fuel Standard (RFS) program,” the Congresswomen said in their letter. “The significant reduction in renewable volume obligations under this proposed rule could destabilize the renewable fuel industry and send the wrong message to investors. This risks jobs and threatens the development of advanced and cellulosic biofuels that bring higher-level ethanol and biodiesel blends to consumers.”

The effort is seen as part of a full-court press by biofuels advocates to reverse the proposal, which ends its comment period in about a week.
