BOISE, Idaho (AP) — The U.S. Department of Energy lists the Idaho National Laboratory as a possible site for storing about 1,300 dump truck loads of low level radioactive waste.

A final environmental impact statement says possible methods of disposal at the 890-square-mile federal site in eastern Idaho include an intermediate-depth borehole disposal facility, a near-surface trench, or in a vault.

The federal agency's preferred alternative according to the document made available in March is the Waste Isolation Pilot Plant geologic repository near Carlsbad, New Mexico.

The INL is listed as a possibility in three other alternatives that also include the Hanford nuclear reservation in Washington state, the Nevada National Security Site and the Savannah River Site in South Carolina. A final decision must involve Congress. The timeline on that isn't clear.
