10. 130 Liberty Street Building Deconstruction World Trade Center Redevelopment New York, New York September 23, 2004 Initial Building Characterization Study Louis Berger Group, Inc.

11. Initial Building Characterization Study, cont. The objectives of the study were to: • Characterize the contamination levels in the building; • Provide recommendations for further sampling; and • Serve as a reference for the development of the cleaning and deconstruction plan. It is important to note that this was only an initial characterization study. LMDC will conduct additional testing and sampling.

12. Initial Building Characterization Study • In May 2004, LMDC contracted with Louis Berger Group, Inc. to perform an initial characterization study of the 130 Liberty Street building. • The goal of the study was to identify any contaminants present in the building that should be addressed during the cleaning and deconstruction process. • The building will be cleaned and methodically deconstructed. As a safety precaution, the deconstruction will not use explosive devices.

13. Initial Building Characterization Study, cont. The study will help LMDC: • Address concerns about community and worker health and safety; • Develop engineering controls and precautionary work practices to ensure public health and safety and protect the environment; • Use cleaning and disposal procedures that properly address all identified contaminants; and • Comply with all applicable federal, state and local regulations throughout the cleaning and deconstruction process.

14. Initial Building Characterization Study, cont. What did the initial study include? • Sampling and analysis of suspect asbestos-containing building materials (ACM); • Sampling and analysis of dust for asbestos and key WTC Contaminants of Potential Concern (“COPCs”) as defined by EPA, as well as other suspected contaminants; • Visual observations for the presence of mold on exposed surfaces; and • Screening of the indoor air for mercury vapors.

15. Methodology • Asbestos Containing Materials (ACM):Approximately 2,000 bulk material samples were taken. • Asbestos in Dust and Other Contaminants of Potential Concern (COPC):Approximately 1,600 bulk-dust samples were taken. Asbestos and dust samples were characterized using either Polarized Light Microscopy (PLM) or Transmission Electron Microscopy (TEM). • Mold:Visual inspection of accessible spaces. • Mercury Vapor:153 samples taken.

16. Methodology The building was divided into six sampling zones that were established based on visible levels of dust and the potential point of entry.

17. Task 1: Study Planning • Sampling and Analysis Plan (SAP) • Quality Assurance Project Plan (QAPP) • Site Specific Health and Safety Plan (HASP)

18. Task 2: Asbestos Containing Material (ACM) • The majority of samples tested negative for asbestos, including spray-on fire-proofing, wall-board, roofing materials, and most thermal insulation for piping and ducts. • Approximately 155,000 square feet of flooring and wall materials, and 95,000 linear feet of caulk, insulation and sealant materials were identified throughout the building as ACM. Most of the ACM are considered “Non-Friable” by state definition. This means that they cannot be crumbled by hand pressure.

19. Tasks 3 & 4: Asbestos in Dust and Other Contaminants of Potential Concern (COPC) • Contaminants of Potential Concern (COPC) identified by the EPA as associated with WTC dust • Asbestos, dioxins, lead, polycyclic aromatic hydrocarbons (PAHs), and crystalline silica • Other Contaminants • PCBs • Heavy metals: barium, beryllium, cadmium, chromium, copper, lead, manganese, mercury, nickel, and zinc

20. Tasks 3 & 4: Asbestos in Dust and Other Contaminants of Potential Concern (COPC) • Approximately 1,600 bulk dust samples were taken throughout the building. • The samples showed varying levels of asbestos, COPCs associated with WTC dust, and other contaminants. • The contaminants were identified in dust located above and below the suspended ceiling (plenum). • Further testing will be conducted on surfaces and in spaces that were previously inaccessible.

21. Tasks 3 & 4: Asbestos in Dust and Other Contaminants of Potential Concern. Although they do not directly apply, the sampling results were compared to EPA’s WTC residential background and 30-year re-occupancy cleanup benchmarks to provide a better understanding of the results. Analytes that exceeded the criteria include: • Asbestos (exceeded in 77% of floors tested) • Dioxin (exceeded in 99% of samples) • Lead (exceeded in 97% of samples) • Quartz (exceeded in 94% of samples) • PAHs (exceeded in 80% of samples) • Chromium (exceeded in 30% of samples) • Manganese (exceeded in 21% of samples)

22. Task 4: Other Analytes in Dust, cont. • Cristobalite, Barium, Cadmium, Copper, Zinc, and Mercury exceeded the criteria in less than 5% of the samples tested. • Nickel, Beryllium, and PCBs did not exceed available residential criteria in any of the samples tested. • PCB levels were compared to the EPA spill cleanup criteria because no residential background or residential benchmark levels related to WTC are available from EPA.

23. Task 4: Mercury Vapors • A preliminary screening for mercury vapor was performed after LMDC acquired the building. • The screening was performed to evaluate potential worker health and safety issues associated with mercury vapor because of its unique ability to vaporize at room temperature. • Based on the measurements obtained from a direct-read screening device, there were no detectable mercury vapor levels in the open spaces within the building.

24. Task 5: Mold • The visual mold inspection revealed building materials with mold on exposed surfaces in seven locations distributed over five different floors (11th, 7th, 3rd, Basement A, and Basement B). • In total, 105 SF of mold-impacted building materials were identified. • Inspection was not performed for non-exposed surfaces and will be performed as part of the supplemental testing for the cleaning and deconstruction program.

25. Summary • The results of the sampling and testing revealed levels of contaminants that should be addressed in the deconstruction of the building. • Throughout the building, asbestos containing materials (ACM) were positively identified. • Detectable levels of asbestos, silica, PAHs, dioxins, PCBs, and heavy metals (including mercury) were also identified in dust above and below the suspended ceilings. • The results are consistent with the highly variable nature of WTC dust and the level of activity that has occurred within the building since September 11th.

26. Further Testing Further testing will occur in previously inaccessible surfaces and interstitial spaces including: • The curtain wall, interior walls, the exterior of the building, and cell systems and raceways within the concrete slabs; and • Testing for all of the constituents addressed in the initial characterization study (asbestos and other analytes as well as visual inspection for mold). Additional testing will also be performed to characterize waste materials prior to handling, transportation, storage, and disposal or recycling.

27. Major Recommendations • Maintain, review, and modify the current health and safety plan and external air monitoring program as appropriate to address the conditions identified in the study; • Continue to review and address the potential for release of contaminants from the building and further develop and implement an emergency action plan; • Conduct further testing as recommended, further develop the cleaning and deconstruction plan, and continue to consult with all appropriate regulatory agencies;

28. Major Recommendations, cont. • Further develop appropriate site-specific health and safety plan and work and site operations documents; • File appropriate notifications and obtain necessary permits, including the Asbestos Control Program 7 (ACP-7), from the appropriate regulatory agencies and engage a contractor with a NYSDOL asbestos handling license to perform the work; and • LMDC should conduct appropriate monitoring and quality assurance/quality control inspections throughout the cleaning and deconstruction process.
