Asbestos identification is determined by the morphology, visual Selected Area Electron Diffraction (SAED), and Elemental Analysis using an Energy Dispersive X-ray Analyzer (EDAX). Concentration on the S=Ashestos structures. comcebic centimeters, mmcnsillimetes <= less than, Flow Rave in fiters per minute filter is catculated by taking the number of asbestos structures and dividing by the area analyzed. Air concentration is calculated by envltiplying the effective filter area (EFA) by the filter concentration and then dividing by the volume of air collected in cubic centimeters (cr). The data pertaining to these calculations can he found on the Ashestns Count Sheet. The ais filter concentration accuracy of the endorsement of products Tha samples collected action is considered A tesait of zero structures in the by NVLAP or any agency of the U.S. Government. telates only to air fiber content. When samples are subrmitiod by an outside agency for analysis, Enviroscience, can ouly guarantee the filters concentration.

This report can not be used to claim response action area demonstrated a filter concentration of asbestos less than seventy structures por square millimeter. This response complete according to EPA 40 CFR 763. . per square millimeter is only applicable to the area analyzed.
