Re: Report of TEM Analysis
Dear Mr. Orlan:
Following are the results of transmission electron microscopy (TEM) analysis of air samples from our Group No. 7455:
Project Name: P.S. 89M, 201 Warren Street, NY, NY Location: All Floors, Playground, Roof, 1st Floor Hallway Samples received: 04/18/02
These results will confirm and document the data transmitted today to Mr. Mark Terjesen, Project Manager, of our office. The analyses were performed in strict conformance with the methodology of the MERA Final Rule (40 CFR Part 763, Appendix A to Subpart E, October 30, 1987) for clearance of abatement sites.
The results of the sample analyses are as indicated on the attached document.
Copies of the bench sheets are also included as stipulated by AHERA. 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 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 MERA 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,
ichael Gorycki, Director of Electron Microscopy
