This document provides information about the U.S. Department of Energy's (DOE) intent to modify the scope of an environmental impact statement for the Abengoa Biorefinery Project near Hugoton, Kansas. Specifically, DOE is amending the scope to assess a proposed change to the project that would include generating electricity from a steam-driven turbine to supply the regional power grid, in addition to producing ethanol from biomass. DOE is soliciting public comments on this proposed scope modification and will hold a public scoping meeting on May 19, 2009 to receive input.
