Preliminary environmental assessment report, 30 Warren Street, January 2006

NYC 9/11 Public Portal Document

Environmental Characterization Report Fiterman Hall, 30 West Broadway, New York, NY Airtek Project #05-0867 — January 10, 2006

While limited visible mold does exist, it will have little or no impact on the planning and execution of the environmental remediation and deconstruction of the building.

2.0 Previous Environmental Investigations

201 Pre-9/11 Asbestos and Lead Reports

In support of the gut renovation that was conducted and nearly completed at Fiterman Hall from 2000 through September 11, 2001, limited ACBM & LBP surveys were conducted. These surveys identified materials that were then subject to abatement during the gut renovation. For the purpose of this study, records of the survey reports and records of the abatement projects conducted in support of the renovations were reviewed. The primary focus of the pre 9/11 abatement projects was ACBM piping insulation on thermal systems. Extensive abatement of these materials was conducted.

2.2 Post 9/11 Environmental Investigations

Following 9/11/01, several consultants were engaged to conduct testing to gauge the environmental impact to Fiterman Hall. Sampling conducted by Applied Technology Services ("ATS"), Howard Bader Consultants ("Bader"), and Tiffany-Bader Environmental, Inc. ("TBE") ("the Environmental Consultants"), confirmed the presence of a wide array of contaminants throughout the Building. The contaminants detected included asbestos, lead, dioxin, heavy metals, mercury, fungi, bacteria, and particulate dust. Other contaminants known to be associated with the WTC dust that can be presumed to exist in areas of Fiterman Hall include polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). The results of these efforts support the conclusion that the entire structure should be assumed to be contaminated.

In 2002, Airtek was engaged to gather and format the environmental data generated and to review the type and extent of contamination reported by the Environmental Consultants.
