Regulated Building Material Inspection Wrerracon Port of Everett Marina - Equator Shed ;1 Everett, Washington June 22, 2023 a Terracon Project No. 81227459 Washington. Samples were analyzed via polarized light microscopy (PLM) in accordance with EPA/600/R-93/116. NVL Laboratories are accredited to perform PLM analysis by the National Institute of Standards and Technology National Voluntary Laboratory Accreditation Program (NVLAP). 3.4 Asbestos Results Table 3.4-1 provides a list of suspect homogeneous material sample descriptions, material locations, and results for this sampling. Also indicated within the table is the AHERA classification of Surfacing (S), Thermal System Insulation (TSI), or Miscellaneous (M). Refer to the attached Figures for sample locations. Refer to the Appendix for photographs that are representative the homogenous materials. Table 3.4-1. Results of Bulk Sample Analyses Material No. Material Description Material Location Results 1 ■ Multi-layered red (M) asphaltic 3-tab roofing Roof of building ND (all layers) ■ Black mastic 2 8 Black asphaltic vapor Roof of building ND (all layers) (M) barrier 3 U White/grey sealant Edges of gutter system on ND (all layers) (M) with debris roof of building 4 3 Grey concrete with Base of building and below ND (all layers) (M) debris corner column posts ND: none detected, Material No.: homogenous material that is uniform in color, texture, general appearance, and construction and application date, M: Miscellaneous material per AHERA. If the analytical results indicate that all the samples collected per homogenous material do not contain asbestos, then the material is not considered an ACM. However, if the analytical results of one or more of the samples collected per homogenous material indicate that asbestos is present in quantities of greater than one percent as defined by the EPA, the homogeneous material is considered to be ACM regardless of other analytical results (unless a representative number of samples have been analyzed by PLM point counting as described below, and the results indicate the material contains less than one percent asbestos). Any material that contains greater than one percent asbestos is considered an ACM and must be handled according to Occupational Safety and Health Administration (OSHA), EPA, and applicable state and local regulations. The EPA National Emission Standard for Hazardous Air Pollutants (NESHAP) 40 CFR 61, Subparts A and M has a requirement related to inspection of suspect ACM in buildings. When the asbestos content of a friable material is visually estimated by PLM to be detectable but less than ten percent, your firm may elect to (1) assume the amount is greater than one percent and treat the material as asbestos-containing or (2) require verification of the amount by the PLM point counting technique. If the results obtained by point counting and visual estimation are different, the point count result must be used. When no asbestos is detected by PLM, point counting is not required.
