Re: Air Sample Results: 17 Battery Street New York, NY

Dear Mr. Budabin:

Following the collapse of the World Trade Center Towers and surrounding properties, EMS of NY was retained by your office to perform baseline sampling within the building to determine if airborne asbestos was present.

On October 3, 2001 EMS tested representative floors and subjected the samples to analysis via Transmission Electron Microscopy (TEM). TEM analysis is deemed state of the art and is able to distinguish between asbestos and non-asbestos fibers.

The results that were obtained indicated that at the time of testing there was a trace of Chrysotile fibers (a form of asbestos) present in the air.

Current acceptable levels as set forth by the Environmental Protection Agency (EPA) are set at 70 s/mm2. The standard of 70 s/mm' is used to determine whether background levels or airborne levels following an abatement project are acceptable for human occupancy. If the concentration exceed 70 s/mm2, then additional testing along with clean-up and possible protective equipment should be initiated.

Overall, based upon the sampling results, the air quality in regards to asbestos, according to EPA standards, is acceptable. However, it is our recommendation that the air be tested randomly to ensue that the asbestos fiber concentrations do not become elevated during the cleanup of the collapsed towers and surrounding buildings.

If you have any questions or require additional information, please contact me.

Sincerely, 1 rc Marc Rutstein Vice President.
