Mr. Bernard P. Orlan July 26, 2002 Wipe Samples for PCBs Page 2 P. S. 150M ATC Project No. 15-19125-0289
The area sampled was the Main Lobby floor. The surface area was 100 square centimeters (lOOcm^).
The samples were analyzed for seven PCB compounds with differing percentages of chlorine.
On each day, the '’CB results for all three samples (and the blanks) were below the reporting limits (2.0 micrograms/sample) for the analysis.
(Currently, the Environmental Protection Agency spill clean-up standard for PCBs on non-porous surfaces is 10 micrograms per 100 square centimeters or less (<10ug/100cm") as stated in 40 CFR 761.
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 37C or 212.
