Dear Joel Kupferman,

I have reviewed the December 9, 7001 report on esbeatoe sampling done by Fd Olmsted, CIH, at 101 Duane Street. concur with Mr. Olmsted's conclusion that the sample taken from the air diffuser in the 10th floor public hallway shows levels of asbestos well above the raeommended limit of 100o structure per square centimeter.

I also concur that the finding of 555,000 aebe5t01 structure per square centimeter is a clear indication that the ventilation system should be cleaned by a professional duct cleaning company using vacuum and cleaning equipment design. •tea tam a~1 I would add that the wor must be one by trained and certified asbestos abatement r o can prevent contamination of other perte of the building while thy wcrk.

I also would add that this single sample should be followed up by other samples taken from other locations in the ventilation system. This sampling must be undertaken immediately because asbestos fibers in ventilation systems are likely to deposit throughout the building. The reading of 740 asbestos structures per square centimeter on the living room table top is high enough to cause concern that further deposition could be hazardous. It the cleaning is delayed until many apartments attain levels requiring abatement, the coat of cleanup will rise exponent-ally.

it is also licel that there are already epartr~ents in the building in w _c he asbestos duet levels are much hi her. These locations are moat likely to ret those in whic e air is supplied by diffusers that are closer to the ventilation system's apartment@ may air intakes and filters. People living in these be at risk now.
