Subject: Ambient Air Sampling at 21 West Street, New York, NY
Dear Ms. Brady:
JLC Environmental Consultants, Inc. (JLC) conducted ambient air sampling at various
locations at the above site on October 18, 2001. The air samples were analyzed using the
Phase Contrast Microscopy (PCM) Methodology. The analytical results of the air samples
using the PCM method indicated that all samples achieved the acceptance criteria of at or
below <0.01 fibers per cubic centimeters.
Based on these results the sampled locations are considered safe for re-
occupancy.
The air sampling and analysis were done utilizing applicable Federal, New York State
and New York City Regulations pertaining to asbestos to include Federal OSHA (29
CFR 1926.58), EPA NESHAPS (40 CFR Part 61), and TSCA Title II AHERA/ASHARA
(40 CFR Part 763) Asbestos Regulations; the New York State Department of Labor
Industrial Code Rule 56 and the New York City Department of Environmental Protection
Title 15 Asbestos Regulations.
Upon review should you have any questions please feel free to contact me at (212) 420-
8119.
Sincerely,
JLC nvironmental Consultants, Inc.
