At the request of Mr. Richard Brooke as agent for NEWMARK & CO. REAL
ESTATE, INC., Consulting & Testing Services, Inc. (CTSI) performed environmental
testing at 100 Gold Street facility. The purpose of the sampling was to evaluate the
building’s air quality and dust composition subsequent to the World Trade Center
tragedy.
Testing was performed from September 17®, 2001 through September 21”, 2001.
• Air samples were collected as part of building air quality evaluation and during
clean up processes from the following floors; IO® floor MER, basement, I* 2" ,
3'^'*, 4®, 5®, 6®, 7®, 8® and 9®. All samples collected were transported to an
independent certified laboratory, EMSL Analytical, for analysis. Samples were
analyzed utilizing Phase Contrast Microscopy (PCM) Methodology (Fiber
Analysis of Air Samples viaNIOSH 7400, Revision 3, Issue 2, 8/15/94).
Based on the attached certificate of analysis, the final air quality samples
collected on September 18® and 19®, indicate fiber counts are within the
Occupational Safety & Health Administration (OSHA) Permissible Exposure
Limit (PEL) of 0.1 free (fibers per cubic centimeter). Total of seventeen (17) air
quality samples were collected.
Air samples collected during clean up phases were within New York State and
City clearance criteria of <0.01 free. Total of sixty-six (66) samples were
collected during clean up phases.
• Dust / Wipe Samples were collected from the following areas: 10® Floor exit to

from debris on the roof and dust/debris from the other locations. A total of fifteen
(15) dust samples were collected.
All samples collected were transported to an independent certified laboratory,
EMSL Analytical, for analysis. Samples were analyzed utilizing Polarized Light
Microscopy (PLM) Methodology qualitative method.
All samples analyzed were tested no detected for the presence of asbestos. CTSI
had performed dust sampling at other adjacent properties and had received mixed
results. Samples from adjacent buildings reporting non detected under PLM
method and re analyzed by TEM (Transmission Microscopy Method) indicated
presence of asbestos fibers.
