The facility encompasses approximately 210 acres and is just west of the Missouri River. Union Pacific Railroad Omaha Shops Facility used the facility for approximately 100 years, with its principle functions as a railroad fueling facility, repair shop, paint shop and body repair shop for the locomotive and car fleet. From the 1950s to the 1988, the facility was a major overhaul and maintenance facility. Maintenance and repair activities involved various hazardous substances, principally paints, paint solvents, caustic cleaning chemicals and degreasing solvents. Some of the wastes generated from these activities were disposed of on-site, resulting in contamination of soil and ground water. In 1988, most of the operations moved out of state. Demolition of the facility began after operations were moved off-site.
