ASBESTOS NORTHWEST LLC SURVEY REPORT A 513 E S T O S NORTHWEST 30620 Pacific Hwy S Suite 103 Federal Way,WA 98003 Tel:253 9414343 Fax:253 9414175 3. Material Sampling Information Asbestos survey work performed by Asbestos Northwest meets inspection regulatory requirements enforced by federal, state, and local agencies, including Asbestos Hazard Emergency Response Act (AHERA), WAC 296-62-077 (WISHA) and 40 CFR Part 61 (NESHAP) and 29 CFR Part 1926.1101 (OSHA) Definitions Homogenous— Materials with the same appearance, texture, color, and which were applied during the same general construction period. Surfacing Material— Material that has been sprayed-on, troweled-on or otherwise applied to surfaces, such as acoustical plaster, texture and joint compound, and fireproofing materials on structural members. Thermal System Insulation — Material applied to pipes, fittings, boilers, breaching, ducts, and other interior structural components to prevent heat loss or gain. Miscellaneous Material — Building materials such as structural components, structural members or fixtures not included in surfacing and thermal insulation. Survey Methodology Before sampling began, inspectors documented the total surveyed area. A sketch of each space was created, and total square footage was roughly measured. The inspectors then determined the extent of each visible homogenous material throughout the survey area. Materials were classified as surfacing, thermal insulation, or miscellaneous material, and friability was assessed according to AHERA specifications. Materials were sampled according to 40 CFR 763.86. Depending on homogeneity, square footage, and material type, the proper number of samples needed to accurately assess the location and extent of asbestos was determined and collected. At the point of collection, samples were placed in an appropriate container and labeled. Location was noted on the building floor plan, and a description of the material was recorded with the label number. Sampling tools were then wiped clean to prevent contamination between samples. Any suspect debris was sealed. The samples were then counted, and their label numbers were recorded on a chain of custody form. The inspector then signed and released the form to the laboratory with the samples. Samples were analyzed in-house at Asbestos Northwest. Below is a list of all materials sampled. Appendix C contains the laboratory report and analytical results for each sample. 6
