Miscellaneous materials require adequately representative sampling, which is typically done by <br /> collecting at least three samples per material. Inspectors typically rely on other survey <br /> observations such as the condition, fiiabilty, and quantity of material to determine what would <br /> be a sufficient amount of samples to accurately evaluate the presence or absence of asbestos <br /> content. ATC reviewed a Prioritization Asbestos Assessment Study conducted by Hall- <br /> Kimbrel Environmental Services dated August 24, 1988. This document was used as a guide <br /> to aid in developing a sampling strategy of suspect asbestos-containing materials. ATC <br /> collected representative samples of suspect materials observed at the site and did not rely on <br /> sampling data contained in this document. <br /> Actual collection of a bulk asbestos sample involves physically removing a small piece of <br /> material and placing it in a marked, airtight container. Sample containers are marked with a <br /> unique identification number, which is also noted in the field notes. Asbestos-containing <br /> building materials identified at the site are listed in the following tables. <br /> 3.4 Suspect Asbestos-Containing Material <br /> One hundred five (105) bulk asbestos samples were collected from the building and one <br /> hundred fifty one (15 1) sample layers were analyzed by Polarized Light Microscopy (PLM) <br /> based on the number of distinct layers (materials) associated with each bulk sample. For <br /> example, floor tile and associated mastic are collected as one bulk sample but are analyzed as <br /> two distinct materials by the asbestos laboratory, as required by the NVLAP. A summary of <br /> identified,accessible suspect and confirmed ACMs follows: <br /> 7 <br />
