OMAHA (DTN) -- The Environmental Protection Agency has opened its own "back-door waiver" to the Renewable Fuel Standard by granting retroactive exemptions to RFS obligations to more than a dozen small refiners, including some that are part of highly-profitable refining conglomerates.
"I smell a rat. I smell a rat," said Scott Irwin, an agricultural economist at the University of Illinois who studies the Renewable Fuel Standard.
In examining how EPA is granting exemptions to RFS obligations, Irwin said, "This is real and there are large uncertainty on the market impacts."
