Mr. Bernard P. Orlan April 4, 2002 Wipe Sampling for PCBs Page 2 Stuvvesant High School fM4771 ATC Project No. 15-19125-0246
The areas sampled were:
• 1 st floor Main Entrance Lobby; • 2nd floor Bridge Entrance Lobby; and • Mixed Plenum-HVAC #2.
Each sample was analyzed for seven PCB compoimds with differing percentages of chlorine.
The PCB results of all samples were below the reporting limits (2.0 micrograms/s ample). The same level was reported in the blank.
Currently, the Environmental Protection Agency spill clean-up standard for PCBs on non-porous surfaces is 10 micrograms per 100 square centimeters or less (<10 ug/lOOcm^) as stated in 40 CFR761. >
It is our pleasure to provide these indoor environmental services to the New York City Board of Education. If you have any questions about this report, please call (212) 353-8280, extension 212.
Sincerely, ATC ASSOCIATES INC.
James R. Cohn, CIH, CSP Regional Manager Industrial Hygiene Division
