Andrew,
There seems to be some confusion here. That ATSDR study you refer to
actually was initiated AFTER residents, et al complained the city was not
doing a good job overseeing analysis/cleanup of asbestos inside the lower
Manhattan buildings. I am not asking about that study, which I assume would
be using the latest in monitoring techniques. I will reiterate my questions
again below to be more clear and ask for prompt response, hopefully end of
business today. Best regards, Jim
1) EPA says it did not assume jurisdiction over the indoor air testing because New York City
DOH insisted it have lead responsibility for that. Then NYC advised lower Manhattan
residents that they were using the 1% OSHA standard for asbestos in dust; i.e. if more than
1% asbestos found in dust, then would have to be properly abated. (The PLM (polarized light
microscopy) microscope has been most commonly used to determine the 1% level.) If not,
no problem.
HOWEVER, numerous private lab tests have found widespread asbestos levels below the 1%
threshold by using a much more sensitive testing device called the TEM (transmission electron
microscopy) microscope. Why so much asbestos below 1%? Because in the collapse of the Twin
Towers the asbestos became atomized into millions of sub-micron particles not readily detected
by the PLM microscopes.
So the question is: Why did New York City continue to follow the 1% standard when it was clear
that standard was of little relevance to this situation?
2)What guidance if any did EPA give NYC in testing/abatement of asbestos?
3)Why was the ATSDR study launched? Is that a concession by the city that perhaps better
testing techniques should have been used all along?
4) Finally, does the city feel the EPA shares any responsibility for the way cleanup and testing
have been handled indoors? In other words, should EPA have asserted its jurisdiction and taken
charge all along??
