. Christopher O. Ward Dear Ms. Grimm;
Commissioner
The New York City Department of Environmental Protection has
reviewed the asbestos air sampling reports prepared by Taylor Environmental
Group, Inc.
The results indicated sampling and analysis was in accordance with the
Asbestos Hazard Emergency Response Act (AHERA) requirements.
According to the submitted reports, sampling was performed in the auditorium,
library, basement, elevators, 1 floor and on the 3” through 10*’’ floors. •
The results indicate the clearance and re-occupancy criteria set forth in
AHERA (70 s/mm^) were met.
Micro-vacuum sampling is not a recognized method for asbestos
sampling. Further, the New York State Department of Health has not
approved the analytical method for the micro-vacuuming samples.
We acquiesce to the Department of Health’s recommendations that the
Department of Education’s carpet-removal protocols would be sufficiently
protective of the health of students, teachers, and staff within the school such
that the removal process itself would not create a risk to health.
Sincerely,
R. Radhakrishnan
