1111 34th Street <br /> Everett,WA 98201 <br /> Project Number:2017-0728 <br /> 2.0 SURVEY METHOD (continued) <br /> Miscellaneous Materials: <br /> 1. Inspector shall collect samples in a manner and number sufficient to determine if the material <br /> is asbestos-containing or not. <br /> All Materials Determined to Be Non-Friable:, <br /> 1. Inspector shall collect samples in a manner and number sufficient to determine if the material <br /> is asbestos containing or not. <br /> In addition to these sampling requirements, the AHERA Building Inspector is required to assess the <br /> following of each material that is found to be positive for asbestos: <br /> 1. The condition of each material; <br /> 2. Accessibility; <br /> 3. Possibility for air erosion. <br /> Once the samples have been collected, they must be analyzed by an accredited laboratory, and they <br /> must be analyzed using polarized light microscopy methods, commonly referred to as EPA Method <br /> 600/R-93/116. <br /> NVL Labs collected samples and obtained analytical data for suspect asbestos-containing materials <br /> identified in the building. Once collected, each bulk sample was sealed in an unadulterated plastic bag <br /> to eliminate the possibility of cross-contamination. "Chain-of-Custody"tracking was followed to maintain <br /> sample integrity during handling and data reporting at NVL Labs. <br /> A walk-through inspection of all accessible areas of the space was performed to identify suspect <br /> asbestos-containing materials. This inspection included a review of the internal and external aspects of <br /> this.structure. The locations and types of potential asbestos-containing materials were,noted. <br /> Homogeneous Materials <br /> Homogeneous materials are defined as an area of asbestos-containing material or presumed asbestos- <br /> containing material which appears similar throughout in terms of color, texture, and date of material <br /> application. The report listing for homogenous materials will appear as follows: <br /> Sample Material Description by Layer Location Asbestos Quantity Friable <br /> Number <br /> Layer 1 is not asbestos-containing 1. % <br /> Location description "X"LFtft2 Yes/No <br /> Layer 2 is asbestos-containing _ 2. % <br /> Lead Survey Method <br /> NVL Labs collected representative samples of paint from the interior and exterior of the building within <br /> the project scope. Once collected, each bulk sample was sealed in an unadulterated plastic bag to <br /> eliminate the possibility of cross-contamination. "Chain-of-Custody" tracking was followed to maintain <br /> sample integrity during handling and data reporting at NVL Labs. Sampling was representative of all <br /> layers of paint. Copies of laboratory reports and field data forms for lead paint are in Appendix B. <br /> NVL Laboratories,Inc. <br /> 4708 Aurora Ave N <br /> Seattle,WA 98103 <br /> Phone(206)547-0100•Fax(206)634-1936 (c/.3-,* <br />
