LUBBOCK, Texas (AP) — The company operating Texas’ only radioactive waste dump site is asking state regulators to allow disposal of depleted uranium and triple the capacity of a burial site that accepts waste from dozens of states.

Although Waste Control Specialists says the uranium stored at its West Texas site would have only low-level radioactivity, opponents say the proposal would get the company another step closer to handling more dangerous material that wasn’t part of the original license. The company has already been in talks with county officials about high-level waste disposal.
