Superfund Record of Decision (EPA Region 10): Union Pacific Railroad Yard, Bannock County, Pocatello, ID. (First remedial action), September 1991. Final report
The Union Pacific Railroad Yard site is an active rail yard located in Pocatello, Bannock County, Idaho. Union Pacific Railroad (UPRR) began operations around the turn of the 20th century. UPRR constructed a treatment plant in 1961 to receive industrial wastewater and surface stormwater runoff from the railyard. Until 1983, sludge from the treatment plant's oil/water separator and from a dissolved air flotation unit was disposed in the onsite sludge pit. In 1983, EPA determined that seepage from UPRR's sludge pit, and from a nearby area where an oil tie treating facility was located were contributing to Upper Aquifer ground water contamination. The Record of Decision (ROD) addresses contamination of the Pocatello Sludge Pit located at the UPRR property. The primary contaminants of concern affecting the soil, sediment, sludge, and ground water are VOCs, other organics including PAHs and petroleum-based hydrocarbons (oils), and metals. The selected remedial action for the site is included.
