Annual Site Environmental Report
The PCB results from the sampling performed in conjunction with the Building K-1035 D&D are
presented below in Figs. 3.31, 3.32, and 3.33. The figures indicate that:
• Concentrations of PCB-1254 and PCB-1260 both increased in the summer 2009 “during demolition”
sampling event,
• All other concentrations of PCBs did not appear to have been affected by the demolition of Building
K-1035.

None of the radiological samples collected as part of the Building K-1035 D&D sampling had results
that were above the screening levels.
The demolition of the building structure at K-1035 was completed in 2009. As part of the D&D
activities that were conducted at this building, the acid pits that were located on the south end of the
building were removed. Visible mercury and other contaminants were found to be present in the former
location of the acid pits. Therefore, remediation of the soil at the south end of Building K-1035 will be
conducted in 2010. Specified manholes will be sampled during the soil removal activities on the south
end of the building as part of the 2010 SWPP Program sampling and analysis plan. EC&P personnel will
assist in planning the times these samples should be collected. In addition, final closure activities are
scheduled to be performed at K-1035 in 2010. Specified manholes and outfalls will be sampled upon
completion of all closure activities at Building K-1035.
