decision to build the plant at this location was based on several factors.
The necessary raw materials were all within a reasonable distance--coal
deposits in Carbon County, iron ore from Iron County, limestone and
dolomite near Payson, and water from Deer Creek Reservoir and on-site
artesian wells. Other advantages were the proximity of the site to major railroad lines and the availability of an educated and stable local
work force. The plant's inland location, though far from major markets,
was selected as a precaution against steel shortages in the West in
case of a Pacific coast invasion or closure of the Panama Canal. This
became an issue of increasing concern after the Japanese attacked Pearl
Harbor in December 1941.
