The highly-anticipated decision by the Environmental Protection Agency on whether to grant a partial waiver of the Renewable Fuels Standard will be announced Thursday afternoon.

EPA Administrator Stephen Johnson and Principal Deputy Assistant Administrator Robert Meyers will hold a press conference at noon central time to officially answer the request from Texas Governor Rick Perry to cut the RFS ethanol blending requirements by 50 percent. EPA received so many public comments on the issue that they had to postpone announcing a decision past the required 90 days after the request was made. The decision was supposed to be made by July 24.
