4.0METHODOLOGY 4.1Asbestos Survey LEI’s State of Hawaii certified asbestos inspector collected a total of three (3) samples of suspect ACM for asbestos analysis. All of the suspect ACM samples were collected from the Subject Site in general accordance with EPA guidelines and recommendations. The suspect ACM were carefully cut out and placed into a labeled re-sealable plastic bag. The sampling equipment was cleaned between each sample collection to avoid cross-contamination between samples. The approximate quantity of each suspected asbestos-containing material was noted. Sample locations were randomly selected in accordance with EPA protocols and recommendations. All samples were properly logged and recorded following strict chain of custody procedure and submitted to Hawaii Analytical Laboratory, LLC in Honolulu, Hawaii for analysis by polarized light microscopy in accordance with EPA Method 600/R-93/116. Hawaii Analytical Laboratory, LLC is accredited for bulk asbestos analysis through successful participation in the National Voluntary Lab Accreditation Program (NVLAP). 4.2Lead Paint LEI’s State of Hawaii certified lead-based paint risk assessor collected three (3) paint chip samples from the Subject Site in accordance with the EPA guidelines and recommendations. The suspect lead-containing paints were wetted with amended water before sample collection. Paint was carefully scraped and placed into a labeled re-sealable plastic bag. The sampling equipment was cleaned between each sample collection to avoid cross-contamination between samples. The sample was properly logged and recorded following strict chain of custody procedure and submitted to Hawaii Analytical Laboratory, LLC for analysis in accordance with EPA method 7000B. 4.3Mercury-Containing Lamps and PCB-Containing Light Ballasts LEI made visual observations to inventory and identify the presence of mercury-containing lamps and PCB-containing light ballasts. Fluorescent light ballasts were inspected for the presence of labeling stating “No PCBs”. If labeling was not observed on the light ballasts and/or if the ballasts were not accessible, the ballast was assumed to be PCB-containing. Fluorescent light bulbs were inspected for the presence of labeling stating “No Mercury”. If labeling was not observed on the light bulb or if the light bulb was not accessible, the light bulb was assumed to be mercury-containing.
