A telling table in BLM's “Reasonable Foreseeable Future” Plan makes obvious that the targeted formation is not Mancos Shale, nor even the Mancos-Dakota interface, but directly into the Dakota Formation directly on top of the drinking-water-bearing Morrison Formation.
Again, this appears to be an EPA-BANNED Class IV well if ANY toxic or carcinogenic chemicals, radioactive tracers, or conceivably even neutron-logging are used in well fracking or waste injection well operations.
The Dakota Formation (Kd) is obvious in the vicinity of the Big Map's Jurassic (J), identified elsewhere as an outcropping of the Morrison Formation (Jm), infra.
