Gentlemen:
Please find enclosed the air monitoring report performed at the above referenced address in the 100. 200, 300, 400 & 500. Air sampling was conducted via Transmission Electron Microscopy (TEM) analysis at the request of the owner.
ATC Associates (ELAP #10879) analyzed the samples using the Transmission Electron Microscopy (TEM) Methodology. The results indicated that the areas achieved the acceptance criteria below <70 structures per mm2 set by the federal regulations. (Please See Attached TEM Report) According to the EPA, "In evaluating data from the World Trade Center and the surrounding areas, EPA is using a protective standard under .4HERA. the Asbestos Hazard Emergency Response Act, to evaluate the risk from asbestos in the outdoor and indoor air. This is a very stringent standard that is used to determine whether children may re-enter a school building after asbestos has been removed or abated. It is based on assumptions of long-term exposure. EPA has chosen to use this standard, because it is the most stringent and protective, even though it is unlikely that the public will be exposed to asbestos from the World Trade Center site for extended periods of time.
To determine asbestos levels, air filters are collectedfrom monitoring equipment through which air in the • school building has passed and viewed through a microscope. The number of structures — material that has asbestos fibers on or in it — is then counted. The measurements must be 70 or fewer structures per square millimeter before children are allowed inside.
There is also a federal standard for asbestos exposure under OSHA, the Occupational Safety and Health Act, which is used to protect workers on-the-job. The standard is . I fiber per cubic centimeter averaged over an eight-hour day. To be as protective as possible, EPA is using the school re-entry standard in tests around the World Trade Center.
Levels above 70 structures per square millimeter do NOT imply an immediate health threat. Asbestos exposure becomes a health concern when high concentrations of asbestos fibers are inhaled over a long period. Illness is very unlikely to result from a single, high-level exposure. or from a short period of exposure to lower levels. The air samples were collected by licensed and qualified personnel.
Sincere ,
