The U.S. Department of the Interior with assistance from the Environmental Science Division (EVS) of the U.S. Department of Energy's Argonne National Laboratory completed the final environmental impact statement (EIS) for the Long-Term Experimental and Management Plan (LTEMP). This final EIS is a comprehensive evaluation of 1,312-MW Glen Canyon hydroelectric facility operations and its effects on the Colorado River through the Grand Canyon. This is the first such evaluation in more than 20 years, EVS says, and it examines flow regimes to meet the goals of supplying water for communities, agriculture and industry and will protect the resources of the Grand Canyon, while providing clean hy-dropower. Interior is expected to produce a record of decision incorporating data from the study that will identify how the department plans to operate Glen Canyon Dam for the next 20 years.
