Asbestos and Lead Paint Inspection Report for 130 Cedar Street, New York, NY 10006

• JLC uses an Olympus BHT-P Polarizing Microscope complete with polarizer, analyzer, port for wave retardation plate, 360 degree graduated rotating stage, substage condenser, lamp and lamp iris, eyepiece reticle, and 25-point Chalkley Point Array. Plane polarized light allows for the determination of refraction indices relative to specific crystallographic orientations. Morphology and color can also be observed under plane polarized light. Observation of particles or fibers while oriented between polarizing filters whose privileged vibration directions are perpendicular allows for determination of isotropism/ anistropism, extinction characteristics of anisotropic particles, and calculation of birefringence. A retardation plate may be placed in the polarized light path for verification of signs of elongation.

NYS DOH ELAP states that Polarized Light Microscopy is not consistently reliable and conclusive in detecting asbestos in floor coverings and similar nonfriable organically bound materials. Before this material can be considered or treated as non-asbestos- containing, Transmission Electron Microscopy must make confirmation.

Transmission Electron Microscopy (TEM) analysis of nonfriable, organically bound (NOB's) materials was performed by EMSL Analytical, Inc. located at 307 West 38th Street, New York, NY 10018. (ELAP#11506, NVLAP# 101048-9).

2.3 SCOPE OF WORK FOR ASBESTOS CONTAINING MATERIALS:

The inspection for asbestos containing materials for 130 Cedar Street included the following locations:

1. Basement 2. Ground Floor 3. Floor 2-12 4. Main and Bulkhead Roofs 5. Terrace Roofs 6. Exterior Façade

The asbestos inspection Involved a thorough visual examination of all areas and sampling of suspect materials that would be Impacted during the proposed return. The following suspect materials were visually Inspected, or sampled during the field inspection:

1. Mastic on Floor 2. Boiler Door Cement 3. Corrugated Pipe & Pipe Elbow Insulation (Various Sizes) 4. Duct Concrete/Cement 5. Red Brick Mortar 6. Sheetrock • 7. 9x9 & 12x12 Floor Tiles and Mastic 8.
