Asbestos identification is determined by the morphology, visual Selected Arca Electron Elemental Analysis using an Energy Dispersive X-ray Analyzer (EDAX). «is calculated by taking the number of ashestos shucties and dividing by the ares analyzed. Air concentration is calculated by multiplying (EFA) by the filter concentration and then dividing by the volume of air collected in cubic centimeters (cc). ese calculations can be found on the Asbestos Count Sheet. ia the response action area demonserated 2 filter concentration of asbestos less than seventy structures per square ciillameter. This response comptcie according to EPA 40 CFR 763. c& per square tnillimeter is only applicable te the area analyzed. Test results only reflect conditions at the dme samples were taken.
