MEMORANDUM
DATE: January 11,2002

3. Advantages of cleanup under Superfund statute
4. Summary risk assessment for WTC fallout

This memorandum compares data for asbestos in settled dusts and air inside residences in the
town of Libby, Montana, which is designated as a Superfund site due to this residential
contamination, and similar data for the interior of buildings in Lower Manhattan contaminated
by fallout from the World Trade Center (WTC). The reasons why the current cleanup of WTC
dusts inside buildings is ineffective is also discussed, along with the advantages in addressing the
cleanup through the Superfund statute.
In addition, this memorandum provides a summary of calculated cancer risks for occupancy of
Lower Manhattan buildings, which was performed in more detail in my December 19,2001
memo.' Whereas high level EPA and NYC officials have stated in sworn testimony and to the
press that there were no such risks,^ the appropriate offices in EPA have been effectively
proscribed from conducting such a preliminary evaluation.
The analyses, projections, and opinions in this memorandum represent my own professional
judgement and do not necessarily represent the official position of the U.S. Enviromnental
Protection Agency, and has not been reviewed by EPA. This memorandum is not intended as
any final or definitive assessment risks from continued and past exposures to asbestos in
Manhattan.
