BOISE, Idaho (AP) — An Idaho official says the U.S. Department of Energy has given the state a two-month deadline to waive parts of an agreement to clean up nuclear waste at the Idaho National Laboratory in southeast Idaho or lose doing important research on spent nuclear fuel.

Idaho Department of Commerce Director Jeff Sayer in a letter to Gov. C.L. "Butch" Otter dated Monday says the federal agency plans to send a 2016 shipment elsewhere if it's not allowed into Idaho.

Sayer says the acting assistant secretary for the Office of Nuclear Energy, John Kotek, in mid-July told Idaho officials about the agency's plans. The research would bring millions of dollars to Idaho. But the federal agency has failed to fulfill its agreement to clean up nuclear waste already at the federal facility.
