The clock is ticking down on the comment period for the expanded Renewable Fuels Standard, better known as RFS2. The Environmental Protection Agency will be taking comments until September 25th – just 18 days from now.

Bob Dinneen, president and CEO of the Renewable Fuels Association (RFA) is urging ethanol supporters to make their voices heard now on this important issue. “I am concerned that (the EPA) get this regulation implemented right,” Dinneen said during an interview last week at Farm Progress Show. “This is the first time the agency has been tasked with the responsibility of determining the carbon footprint of an industry and they are learning that’s not an easy thing to do and there is no scientific consensus to do it.”

Dinneen calls the principal of indirect land use being considered by the EPA “not just not scientifically sound, but silly” because it literally equates an acre of land used to grow ethanol in the United States with an acre of Brazilian land forest being destroyed. “This is a very big issue and we’re a long way from having it resolved.”

RFA has provided a simple way for people to make comments to the agency through an online advocacy tool at the website ChooseEthanol.com. Comments need to be received by EPA no later than September 25, 2009.
