I Mr. Bernard P. Orlan April 22, 2002 Wipe Sampling for PCBs Page 2 Stuyvesant High School (M477) ATC Project No. 15-19125-0246
, The areas sampled were:
• 1 st floor Main Entrance Wall; • 2^^^ floor Bridge Entrance Wall; • Mixed Plenum - HVAC #1 (March 27); • Mixed Plenum - HVAC #2 (April 3).
Each sample was analyzed for seven PCB compounds with differing percentages of chlorine.
The PCB results of all samples were below the reporting limits (2.0 micrograms/sample). 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.
