Not a secure location
This is being sited about ten miles from the major fault in the Salt Lake area, and if I remember correctly, is sitting it on one of the smaller ones. The last major slip in the area included (still visible) a 50 foot (~16 meter) vertical displacement along the Wasatch front.
Like Seattle, Salt Lake is waiting for "the next big one". Placing such a large facility within this proximity to the fault is, perhaps, not that wise a decision.
