Re: Report of TEM Analysis
Dear Mr. Sallemi:
Following are the results of transmission analysis of air samples from our Group electron microscopy (TEM) No. 9035: Client: D.E.P. Project Name: D.E.P. Clean-up, 125 Cedar St., NY, NY Location: Entire Building Samples received: 10/28/02
• These results will confirm and document the data transmitted today to your office. The analyses were performed in conformance the methodology of the AHERA with Final Rule (CFR October 30, 1987) clearance of abatement sites. for
The results of the sample analyses may be found on the •
document. attached
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. We are pleased to note that our TEM lab has received full accreditation from NVLAP, as is currently analysis of TEM air samples for AHERA required for recognized under the NY State DOH ELAP projects, and also approval 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,
