In Cheyenne Thursday, federal land managers are wrapping up their final public meeting on a proposed plan that is expected to map out the future of oil shale mining on public lands. The Bureau of Land Management is taking what it calls a “fresh look” at the energy resource in Wyoming, Utah and Colorado, as the Obama Administration considers shelving a controversial Bush Administration plan that opened up nearly two million acres of land for potential leasing. The agency will now begin writing what’s expected to be another exhaustive study and that’s reopening an ages-old debate.
