Title: Remedial investigation Phase 2 supplemental work plan for the Hanford Site 1100-EM-1 Operable Unit

The 1100 Area, the central warehousing, vehicle maintenance, and transportation operations center for the Hanford Site, was designated an (NPL) National Priorities List site in July 1989. This NPL site was divided into four operable units, and the first equipment maintenance operable unit, 1100-EM-1, was assigned the highest priority. The following summary focuses on the major issues related to contaminant sources, meteorology, surface hydrology, geology, pedology, hydrogeology, and ecology. The 110-EM-1 Phase 1 R1 report recommended further investigation at six waste management units assigned to or within the operable unit. 1100-1 (Battery Acid Pit)--an unlined dry sump, or french drain, used for the disposal of waste acid from vehicle batteries; 1100-2 (Paint and solvent Pit)--a former sand and gravel pit subsequently used for the disposal of construction debris and, reportedly, waste paints, thinner, and solvents; 1100-4 (Antifreeze Tank Site)--The site of a former underground storage tank used for the disposal of waste vehicle antifreeze; UN-1100-6 (Discolored Soil Site)--the location of an apparent disposal event onto the ground surface involving a container of organic waste liquids; Horn Rapids Landfill--a solid waste facility used primarily for the disposal of office and construction waste and the burning of classified documents; asbestos, sewage sludge,more » fly ash, and, potentially, drums of unidentified organic liquids alleged to be disposed at this location; and Ephemeral Pool--the location of 1100 Area parking lot runoff accumulation during infrequent, high-intensity precipitation events. This remedial investigation supplemental work plan details the efforts for final characterization of the 1100-EM-1 Operable Unit that will provide data to be used for the evaluation of remedial operations in the Phase 3 1100-EM-1 feasibility study. 19 refs., 28 figs., 2 tabs.« less
