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. 5733.

Client: Bellmarc Project Name: 71 Murray Street Location: Floors 10, 8, 5, 3, Lobby Samples received: 10/20/01

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 five samples submitted from the site.

Results reported as Struct/ce 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 riot 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 Dar. Michael A. Gorycki, Director of Electron Microscopy.

We are pleased to note that our TEM lab has received fi,,._],1 accreditr~tion from NVLAP, as is currently required for recognized analysis of TEM air samples for AI-ICkA 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,

/icha - el A. Cory'cki, D. Director of Electron Microscopy
