Mr. Bernard P. Orlan January 28, 2002 Wipe Sampling for PCBs Page 2 Stuwesant High School /Manhattanl ATC Project No. 15-19125-0246
• 2nd floor bridge entrance hallway - wall; • AC#2 mixed air plenum - floor (on January 18, 2002). • AC#1 mixed air plenum - floor (on January 9, 2002).
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 blanks.
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,T00cm2) 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 or 261.
Sincerely, ATC ASSOCIATES INC. 1
