It has to do with a new technology for a greener diesel engine, used in
Daimler, VW and Audi vehicles -


"... a Selective Catalytic Reduction (SCR) catalytic converter will convert
the remaining nitrogen oxides to nitrogen and water; so-called diesel
exhaust fluid (solution of urea and water) is injected into the exhaust gas
stream to enable the conversion."

Given the position of the Urea tanks in the drawing, this use is pretty
much the only one that makes sense.  I would think that requiring this
facility to be environmentally conscious is a sort of payback for what the
Army Corps of Engineers built out in Tooele -


There were a number of folks in Salt Lake City that were up in arms about
its placement with the idea that a catastrophic failure would have
innumerable consequences on the leeward side of the facility.
