Re: Report of TEM Analysis
Dear Mr. Sarett:
Following are the results of transmission electron microscopy
(TEM)
analysis of air samples from our Group No. 5642.
Client: Midetate/Lefrak, Gateway Plaza
Project Name: Bldg. 400, 375 South End Avenue, NY, NY
Location: various Sites
Samples received: 10/09/01
These results will confirm and document the data transmitted today
to you. The analyses were performed in strict conformance with the
methodology of the AHERA Final Rule (CFR October 30, 1987) for
clearance of abatement Sites. As indicated on the attached Summary
Results sheet, no asbestos structures were detected in any of the
thirty samples submitted from the site.
Results reported as Struct/cc are a function of air volume
collected in the field and are, as such, not verifiable by this
laboratory. This report may be reproduced only in its entirety and
not without prior permission of this laboratory. If the post-
abatement inside samples pass, the response action may be
considered to have been completed. The analyses were supervised by
• Dr. Michael A. Gorycki, Director of Electron Microscopy.
We are pleased to note that our TEM lab has received full
accreditation from NVLAP, as is currently required for recognized
analysis of TEM air samples for AHERA projects, and also approval
under the NY State DOH ELAP program. These analyses were performed
by ATC d/b/a ATC Associates Inc_
Please contact me regarding any questions relating to these
materials.
Very truly yours,
Michael A. Gorycki, Ph.D.
Director of Electron Microscopy
