As discussed in the Wildlife Mitigation Plan, American Soda is
considering alternate processes which would eliminate the need
for cooling towers. In the event cooling towers are ultimately
unnecessary, estimated water consumption would decline by 119.4
acre-feet to a total of 1084.4 acre-feet per year.
Dudley Bluffs bladderpod, Dudley Bluffs twinpod, Parachute penstemon, and Uinta Basin
hookless cactus
In preliminary meetings, BLM informed American Soda
representatives that two threatened plant species, Physaria
obcordata (PHOB) and Lesquerella congesta (LECO), occur in the
vicinity of their Piceance site, and that as the lease
encompasses potential habitat as outcrops of the Thirteenmile
tongue of the Green River formation, mining activity could be
subject to No Surface Occupancy stipulations as conditioned by
the results of site-specific surveys.
As developed in our recent Resource Management Plan, a no surface
occupancy stipulation is applied to mapped populations and/or
potential habitat of listed and candidate plants outside of
designated ACECs, namely populations of Dudley Bluffs bladderpod,
Piceance twinpod, White River penstemon, and Graham's
beardtongue. An exception to the stipulation may be granted if
an inventory and subsequent environmental analysis indicates that
the nature or conduct of the action, as proposed or conditioned,
would not adversely influence plant populations (i.e., the
stipulation is excepted on potential habitat where surveys verify
the site unoccupied by these plants).
