The Former IBM Endicott Facility Operable Unit Number Five

The IBM Endicott Facility site is located in the Town of Union in Broome County, New York. The 135-acre facility lies along and on either side of a railroad corridor in the village and in the town. The central portion of the facility is approximately at the intersection of McKinley Avenue and the railroad in the village. Portions of the facility extend westward to Robble Avenue, northward to Watson Boulevard, eastward to Harding Avenue, and southward to south of North Street. Operable Unit 5 (OU5, the Building 57 Area) is located at the eastern end of the former IBM facility, immediately east of Hayes Avenue between North Street and Wayne Street. OU5 is entirely within the Town of Union, and is the only part of the former IBM site outside the Village of Endicott.

Operable Unit 5 (OU5), also known as the Building 57 Area, is the source area and groundwater plume associated with Building 57/57A which is separate from and east of the main facility. OU5 includes Building 57/57A east of Hayes Avenue and north of the railroad tracks, as well as a former parking lot (known as Parking Lot 26) south of the railroad tracks

The site includes numerous current and former manufacturing buildings, office buildings, and ancillary support facilities. Paved parking areas are generally located around the periphery of the site buildings. An east-west railroad corridor bisects the facility and several public and private roadways intersect or transect the facility. Commercial, industrial, and residential areas surround the facility on all sides. The former Endicott Forging facility, a State Superfund site, is adjacent to the southeast portion of the former IBM facility. The Susquehanna River is approximately one mile south of the facility. Brixius Creek, a small tributary to the Susquehanna, passes along the eastern edge of the facility. The facility is served by municipal water supply, sanitary sewers and storm sewers. A private well field also supplies production water for manufacturing purposes. Operable Unit 5 site features include two contiguous buildings, Buildings 57 and 57A, located north of the railroad, two small parking lot parcels across Wayne Street from Building 57, and the former Parking Lot 26 located south of the railroad.

Based on the results of the investigations, the IRMs that have been performed, and the evaluation presented in the March 2016 Record of Decision, the Department is selecting No Further Action as the remedy for Operable Unit 5, Building 57 Area. This No Further Action remedy includes continued operation of the groundwater extraction and treatment and soil vapor mitigation interim remedial measures, and continued implementation of the institutional and engineering controls as part of the proposed remedy.
