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

is 2.1 ASBESTOS INSPECTION & BULK SAMPLING PROCEDURES:

The asbestos inspection procedures were based on the guidelines established by the Asbestos Hazardous Emergency Response Act (AHERA), as set forth in 40 CFR Part 763 of October 30, 1987. The AHERA guidelines represent the most up-to-date inspection and sampling protocol available and as such were utilized during the inspection and sampling. For the purposes of this inspection, suspect ACM has been placed in three (3) material categories: Thermal Systems Insulation (TSI), Surfacing Materials and Miscellaneous Materials.

All accessible areas of the building at 130 Cedar Street were inspected physically, functional space by functional space and homogeneous area-by-homogeneous area to determine the presence or absence of asbestos-containing materials. No demolition was done for sampling purposes because the facilities are fully operational and are currently being used by building occupants. Electrical wiring insulation was not sampled or inspected because electric power could not be shut off.

Suspect materials that may be present inside wall cavities, electrical wiring or which were otherwise inaccessible were not included in the scope of this inspection. Core samples of friable and non-friable suspect materials were collected by penetrating the suspect material to its substrate. The bulk samples collected were placed in sealed containers, labeled with an identifying code and a sample log was kept. Representative samples of each sampling area were then submitted to the laboratory to be analyzed for asbestos content. The inspection Involved the following tasks:

1. A visual determination as to the extent of visible and accessible suspect materials and conditions of the material. 2. Collection of suspect building materials for asbestos content. 3. All suspect friable and nonfriable materials were quantified in their respective locations. 6. All suspect materials sampled were identified on the appropriate building floor plan diagram with an identifying sample number. 7. A Chain of Custody record was prepared to accompany bulk samples to the laboratory.

The assessment process includes classifying the material as Friable ACM or Non-Friable ACM. Friable ACM is the term given to any material that contains more than one percent (1%) asbestos by weight and can be crumbled, pulverized, or reduced to powder by hand or mechanical pressure. The word "Friability" refers to a material's likeliness to release airborne fibers when in situ, or under mechanical pressure. There is a greater possibility that a friable material will release fibers into the air when disturbed than will a non-friable material (i.e., floor tiles, roofing materials, etc.) thereby causing a potential hazard.
