They (the BLM) do not want to permit the plant to be constructed on the land Bundy uses.
They want the land Bundy uses to mitigate (offset) other land they will free up for construction of the power plant.
Below is the incriminating document that has been scrubbed.
Specifically, look at the 8th "dotted" item:
(Non-Governmental Organizations have expressed concern that the regional mitigation strategy for the Dry Lake Solar Energy Zone utilizes Gold Butte as the location for offsite mitigation for impacts from solar development, and that those restoration activities are not durable with the presence of trespass cattle")
I’ve added that to the BLM files at the dropbox. Thanks for posting it.
