(EH&E) for Fitzemeyer & Tocci, Inc., to identify asbestos- containing materials, lead in paint, polychlorinated biphenyls (PCBs), and other hazardous building materials in anticipation of renovations planned at the Lederle Graduate Research Center (LGRC) low rise building. A report documenting the survey was submitted to the University on March 25, 2009. During the assessment, a sample of the interior window glazing from the third floor conference room of the Science Library was collected and analyzed for PCBs. This sample and a duplicate of this sample detected total PCBs at concentrations of 12,000 parts per million (ppm) and 11,000 ppm, respectively. Given that these concentrations exceed regulatory thresholds per Federal regulations (40 CFR 761) for PCBs in a non-totally enclosed manner, the University retained the services of Woodard& Curran to work with the University to develop an approach and plan to address these conditions. This memorandum presents the results from an initial assessment of the window glazing performed in April/May 2009 and summarizes existing indoor sample data collected within the LGRC building. INITIAL ASSESSMENT This initial assessment included an inspection and inventory of the windows in the low rise and Tower A of the LGRC followed by the collection of representative samples for PCB analyses.
