A Las Vegas Sun investigation reveals that the law firm hired by the Energy Department to do legal work on the Yucca Mountain repository has been lobbying to get the project built. The Energy Department manages the proposed Yucca Mountain project, a federal proposal to bury tens of thousands of tons of nuclear waste at the site about 90 miles northwest of Las Vegas. The plan is controversial, environmentalists say its a bad idea, the nuclear energy industry says its needed. The Energy Department hired Chicago-based Winston & Straw to "independently review Yucca documents and impartially advise the DOE about possible flaws." But the Las Vegas Sun learned that Winston & Straw also does lobbying work for the Nuclear Energy Institute, the energy industry's top trade group and the "most vocal Yucca proponent in Washington." Nevada lawmakers contend that Winston & Straw involvement with the NEI and DOE presents a dangerous conflict of interest.
