NYC 9/11 Public Portal Document

Motivation for NYC deletion of the Centre/Chambers as well as the Spruce/Gold data - concealment offact that contamination went east ofBroadway and north of Warren Street In the altered 2002 version, NYC not only deleted the high levels of 123.73 and 157.48 for ■ the Centre/Chambers and Spruce/Gold locations, it also deleted any mention of the fact that it had ever taken samples at these locations. This was true not only for the electron microscope data (TEM), but also for the light microscope (PCM) data that posted sometime before 10/24/01 on its web site. Both of these two locations are east of Broadway and north of Warren St. NYC was actively concealing the fact that any contamination had gone east of Broadway and north of Warren. See the following 9/17/01 NYC advisory to residents, which explicitly states there are no contamination concerns outside of these boundaries: ’’ If you were evacuated from a residence or workplace south of Warren Street, west of Broadway, and north of Exchange Street, and have been approved to resume tenancy by your building manager, you are advised to wear a dust mask upon entering this area to decrease the possibility of dust inhalation and throat irritation. Outside these boundaries, masks are not necessary, but may be worn for your own comfort. If there is dust present indoors, it should not be necessary to wear this mask if you follow the cleaning procedures detailed below....

Obscure early EPA data collaborates NYC data showing asbestosfurther north of Ground Zero Early EPA data*^ collaborates the NYC findings of high asbestos further north fi-om Ground Zero. Air monitoring was conducted at the EPA Region 2 building in NYC, which is 6 blocks northeast of the perimeter of Ground Zero. This EPA data is difficult to find, and EPA falsely claimed in a press release and other statements to the press that they were not concerned. Significant levels of airborne asbestos were found, although not over EPA's 70 s/mm^ standard of the time. See the table below:
