More than 160 members of the House of Representatives have sent a letter to Environmental Protection Agency (EPA) Administrator Gina McCarthy urging her to consider a fair and meaningful adjustment to the ethanol mandate in the Renewable Fuels Standard (RFS).  The members stated, “Due to the dramatic expansion of corn ethanol, volatile corn prices have led to the conversion of millions of acres of sensitive wetlands and grasslands into production.  Prompt action by the EPA can help to ease short supply concerns, prevent engine damage, save jobs across many U.S. industries and keep families fed.”  The letter was coordinated by Congressmen Bob Goodlatte (R-VA), Jim Costa (D-CA), Steve Womack (R-AR) and Peter Welch (D-VT).
