At any time during the survey, the Inspector can elect to assume <br />that a specific material is asbestos containing, and thereby forego sampling requirements for <br />that homogeneous area. Samples, as appropriate, will be collected in general conformance <br />with the procedures outlined in the Asbestos Hazard Emergency Response Act of 1986 <br />(AHERA). <br />Sample collection will involve extraction /separation of approximately 1 to 10 cubic centimeters <br />of the suspect material, inclusive of all layers present within the material. Only suspect material <br />samples will be submitted for laboratory analyses. Samples will be sealed in airtight containers, <br />numbered and labeled, and forwarded to an approved laboratory for analysis by the EPA <br />recommended method of Polarized Light Microscopy (PLM) coupled with dispersion staining. <br />Sampling and analysis of suspect materials is performed in an effort to try and confirm the <br />presence of asbestos, or eliminate suspect materials as ACMs. Elimination of a material as <br />ACM for purposes of maintenance, renovation or demolition occurs if: 1. the material is visibly <br />non -ACM (fiberglass and rubberized materials), 2. documentation indicates that the materials <br />used in manufacture are non -ACM, or 3. sampling and analysis are performed. <br />According to OSHA Construction Standards, negative analysis for a minimum of three (3) <br />samples is required to conclusively determine a material as being non -ACM. In addition, all of <br />the samples must be from the same homogeneous area (color, texture and estimated date of <br />installation). Wightman Petrie will attempt, through application of our sampling strategy, to <br />make a determination of the asbestos content of any identified homogeneous materials for <br />which sampling is in fact performed (i.e., certain materials may be assumed to be asbestos - <br />containing). <br />
