Democratic Senators Ask Icahn, EPA's Pruitt on Refinery Waiver Details

Six Democratic senators have asked investor Carl Icahn and Environmental Protection Agency Administrator Scott Pruitt to explain how an Icahn-owned refinery secured an EPA exemption from the nation's biofuels law.The request was made in letters sent late on Tuesday and reviewed by Reuters, which reported last week that EPA granted a small refinery hardship waiver from the nation's biofuel laws to an Oklahoma refinery operated by Icahn's CVR Energy Inc., allowing it to avoid costs related to the Renewable Fuel Standard (RFS)."We ... are troubled that a company that is owned by a billionaire former 'special adviser' to the president who is currently under investigation by federal prosecutors ... has now received an 'economic hardship waiver'," the senators wrote in the letters to Icahn and Pruitt.
