Sampling Methodology


34/54

Asbestos Sampling Protoco l

This survey was conducted using a protocol adapted from the Asbestos HazardEmergency Response Act (AHERA). The protocol is as follows:

1. Group materials into homogeneous sampling areas based on visual observations

and information provided about the sidewalk tunnel renovations.

2. Quantify each homogeneous sampling area and collect samples from each areausing the "3-5-7" criteria for surfacing material to determine the number ofsamples needed. Quantify and collect a minimum of three samples of eachthermal system insulation. The number of samples collected of miscellaneousmaterials was determined by the inspector.

3. Samples were collected from areas of easy access and minimum disturbance tobuilding occupants.

4. Samples of each material were taken to the substrate, ensuring that all

components of the material were included.

5. Sampling was performed by an AHERA accredited building inspector.

Asbestos Sampling Procedure

1. Label sample container with unique identification number. Record samplenumber, sample location, type of material, and approximate material quantity ondata form.

2. Extract sample using a clean knife or other tool to collect approximately onetablespoon of the material. Penetrate all layers of material.

3. Place sample in a container and tightly seal it.

4. Clean tools with wet wipes. Clean any material debris from sampling area.

Asbestos Laborato ry Analysis

The bulk samples were analyzed by RGA Laboratory using polarized light microscopy(PLM) with dispersion staining in accordance with US EPA method 600/R-93/116 asspecified in 40 CFR Chapter I (7-1-93 edition) Part 763, Subpart F, Appendix A, pages499-504. Polarizing light microscopy quantifies asbestos concentrations at between100% and 1% detection levels. Levels below 1% can only be stated as "trace" or less

than 1% (< 1%). RGA Laboratory is a member of the National Voluntary LaboratoryAccreditation Program (NVLAP), NVLAP Code #200613-0. Samples were not analyzedby point count to determine asbestos concentrations.

For samples containing more than one separable layer of materials, the laboratory reportwill include findings for each layer (labeled L-1 for layer one and L-2 for layer two, etc.)and a total percentage for the entire sample, if applicable. The asbestos concentrationin the sample is determined by visual estimation.
