In the aftermath of the September 11th collapse of the World Trade Center Towers, the New York City Housing Authority's (NYCHA) Technical Service Department and Employee Health & Safety Compliance Office worked closely with the AmTrust Realty Corporation (AmTrust) to insure that NYCHA's Offices in 250 Broadway were safe for re- occupancy by September 21, 2001. Prior to reopening 250 Broadway, AmTrust followed both the New York City's Department of Citywide Administrative Services (DCAS) and Department of Environmental Protection (DEP) published procedures for reopening a building, after the disaster, in Lower Manhattan (see Attachment F for copies of those procedures). Both AmTrust and NYCHA performed environmental sampling and specialized dust cleaning because of potential contamination from the smoke and dust that was released the into the air following the collapse of the Twin Towers. The plume of smoke from collapse contained dust, ash, soot, and other burning materials present at the site and both parties were concerned that the plume might have contaminated the HVAC system units, and building envelope. NYCHA visually assessed the building's air handling evidence that the plume supply ducts and NCYHA spaces and found no visual contaminated the building. Both AmTrust and NYCHA collected asbestos and lead dust samples; no asbestos was detected in any of the samples but elevated lead in NYCHA used levels were found in several of the dust samples. Please be aware that (1.tglft2), the most protective standard under HUD, 40 micrograms of lead per square foot within the air handling units and tenant to evaluate the risk from lead in the settled dust to determine whether children may spaces. This is the federal residential standard used or abated, as children are much re-enter an apartment after lead has been removed AmTrust more susceptible than adults to the dangers posed by exposure to lead. Both spaces until all dust sample and NYCHA cleaned the air handling units and NYCHA results were below 40 µg/ft2. and Health The U.S. Environmental Protection Agency (EPA) and Occupational Safety state, and local agencies, Administration (OSHA), working closely with other federal, and drinking water and have been sampling the air, dust, water, river sediments radiation, mercury and analyzing them for the presence of pollutants such as asbestos, hazards.
