Re: Asbestos Ambient Air Monitoring From Basement through 12th Floor at
9-11 Murray Street, New York, N.Y.
ATC Project No. 15-21496-01 via fax at 212-757-3212
Dear Mr. Barber:
ATC Associates, Inc. (ATC) was retained by Kellogg Properties to conduct asbestos air
sampling at the above referenced site. Mr. Tim Amstislayskiy performed the air sampling
from Wednesday, September 26" through Friday. September 28''' 2001. All Air samples
were analyzed via Phase Contrast Microscopy. (PCM) on basement through 12"'floor &
Transmission 11cctron Microscopy (TEM) for the tenant on 3rd floor.
A total of 66 samples were taken throughout the above-mentioned floors via PCM and 5
samples via TEM. All air-sampling results via PCM for the ambient areas were below 0.01
fibers per square centimeter (f/cc), and via TEM on the 3`d floor show airborne structure
concentrations to be less than 70 structures per Millimeter Square (s/mm), which meets the clearance
criteria following all City, State and Federal. Regulations for both. PCM & TEM. The area is
now ready for re-occupancy.
Attached please find the results for the air samples taken. If you have any questions or
require further assistance with this matter, please feel free to contact me at 212-353-8280 ext.
257 at your earliest convenience,
Sincerely,
