LAS VEGAS (AP) — A Bush administration bid to win approval for a national nuclear waste dump outside Las Vegas was challenged Wednesday by the state as too little and six years too late.

State Attorney General Catherine Cortez Masto asked the Nuclear Regulatory Commission not to register the license application or schedule it for hearings, calling it "legally deficient."

Energy Secretary Samuel Bodman earlier declared that the application to build and operate the Yucca Mountain repository "will stand up to any challenges from anywhere."

The commission's primary job will be to determine whether the proposed design will protect public health, safety and the environment for as long as a million years.
