Re: Environmental Testing

Dear Ms. Orange,

H. A. Bader Consultants, Inc. performed asbestos testing in representative areas throughout 115 Chambers Street on October 19, 2001. The sampling was performed by Howard Bader, P.E. and Richard Massari of H. A. Bader Consultants.

H. A. Bader Consultants is licensed by the New York State Department of Labor (DOL) as an Asbestos Consultant. Mr. Bader and Massari are New York City Department of Environmental Protection (DEP) Certified Asbestos Investigators. In addition, Mr. Bader and Massari are Certified by the DOL and United States Environmental Protection Agency (EPA) Asbestos Hazard Emergency Response Act (AHERA) Program as Asbestos Air Sampling Technicians, Inspectors, Management Planners and Project Monitors.

Several buildings at and adjacent to the World Trade Center Complex in lower Manhattan were destroyed or severely damaged on or around September 11, 2001. It is common knowledge that some of these buildings contained asbestos containing materials (ACM). It is suspected that debris from the damaged buildings became airborne and potentially contaminated areas in lower Manhattan with asbestos fibers.

H. A. Bader Consultants scope of work was to determine if there is a potential asbestos related health concern in the building. The primary pathway for asbestos and lead to enter the building is through the ventilation systems, the main building entrances and operable windows. There are two air handling units (AHU) that have outdoor air capability. H. A. Bader Consultants performed asbestos testing at the outdoor air intake of each AHU.
