The survey for this building was done in accordance with EPA regulation 40 CFR 763 Subpart E Asbestos Hazardous Emergency Response Act (AHERA). The asbestos survey was completed as required by the State of Washington. Suspect building materials were collected and analyzed by a National Voluntary Laboratory Accreditation Program (NVLAP) laboratory for asbestos content using polarized light microscopy (PLM). Site Address: 21702 98th Avenue West Edmonds WA 98020 Reporting Purposes the Building is assumed to face: East All positive sample(s) if any are identified in the main report. Samples may contain specific area comments that are noted within the sample lab data. Please read this report in its entirety. The attached floor plan indicates the structure layout that pertains to the survey that was conducted. Any detached structures or areas not shown in the floor plans are exempt from the performed survey. Removal of Carport, Concrete Slab/Walk, Rear Deck and basement window (siding/drywall). None of the materials samples had asbestos fibers detected.

AHERA regulations regarding sampling were used to determine the number of samples of homogeneous materials. Full -depth wall and ceiling samples were collected. Samples were collected to include possible joint compound. The areas were wetted before sampling and plastic and duct tape were used as mini -enclosures to minimize dust when occupied. Ceiling and floor tile when sampled were collected using a utility knife and similar wetting and containment. All samples were labeled and double zipped bagged before being transported to the laboratory for analysis. Surfacing materials were sampled in a statistically random manner representative of the homogeneous area at the minimum rate of three bulk samples for areas less than 1,000 square feet, minimum of five bulk samples for areas between 1,000 and 5,000 square feet, and seven bulk samples for areas over 5,000 square feet. Thermal system insulation sampling is not required by AHERA if it is fiberglass, rubber, or other non -ACM. Miscellaneous materials included floor and ceiling tiles and mastics. Consistent with AHERA, we collected a quantity of miscellaneous materials samples that is sufficient to determine whether a material is ACM. Lab testing was performed by NVLAP accredited PLM laboratory, NVLAP Survey procedures included the visual observation and identification of building materials suspected of containing asbestos, collection of representative bulk samples, and physical assessment/quantification of the suspect materials. The physical assessment of suspected asbestos -containing materials was conducted to determine if the material is friable and to assess if the material is damaged. According to AHERA, a "friable" material can be reduced to dust or powder with hand pressure. Examples of friable materials may include but are not limited to fireproofing, sprayed -on acoustical ceiling material, paper backing on sheet vinyl flooring, and some thermal system insulation. Concern related to exposure to airborne asbestos fibers from ACMs in buildings has primarily been focused on friable asbestos products. Materials that contain tightly bound asbestos fibers are reported as "non -friable". A "non -friable" material contains asbestos fibers that have been locked -in by a bonding agent, coating, binder, or other material so that fibers are not released during appropriate use or handling. Vinyl floor tile and flooring mastics are two examples of non -friable materials. Fiber release is less likely to occur with a non - friable material. Non -friable materials that are not damaged and are left undisturbed are not expected to represent an asbestos exposure risk. Both friable and non -friable materials can present a health hazard should they become disturbed or damaged (e.g., during renovation or demolition activities). ACM in good condition is those that have no visible damage or deterioration. ACM in good condition does not present a health hazard if maintained in such a condition and left undisturbed. An ACM observed to be damaged (less than 10 percent over a total area or 25 percent localized) has the potential to release asbestos fibers if disturbed. An ACM observed to be significantly damaged (greater than 10 percent over a total area of greater than 25 percent localized) has the potential to release asbestos fibers during normal use. Bulk samples were collected in general in accordance with AHERA guidelines. Each sample was placed into a plastic bag and labeled with a unique sample number. The location of the sample was noted on a map of the building and logged onto a chain -of -custody form. Flooring, Mastic, and Roofing materials sampled under the PLM method. With non -detect results, we recommended for TEM lab analysis. "Polarized -light microscopy is not consistently reliable in detecting asbestos in floor coverings and similar non -friable organically bound materials. Quantitative transmission electron microscopy is currently the only method that can be used to determine if this material can be considered or treated as non -asbestos containing." Building Assessment An Asbestos Hazard Emergency Response Act (AHERA)-accredited building inspector from Pacific Northwest Inspections Group performed the sampling for the client noted in this report. The sampling was conducted using a modified protocol adapted from AHERA. The protocol is as follows: Identify suspect asbestos -containing materials Group materials into homogeneous sampling areas/materials Quantify each homogenous material and collect representative samples Samples of each material were taken to the substrate, ensuring that all components and layers of the material were included Sample locations are referenced the field data forms according to sample number Sampling was performed by an AHERA-accredited building inspector, and the use of proper protective equipment and procedures was followed where required. Sampling Procedures Pacific Northwest Inspections croup-425.608.9553 Page 3 of 5 148 165th Ave NE, Bellevue, WA 98008 1' N �►�I C�� Inspection Services Based on the findings of the visual assessment, bulk samples of suspect ACM were collected in general accordance with AHERA sampling protocols. Random samples were collected for each suspect homogeneous material identified. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker and/or printed label. Asbestos Results If the analytical results indicate that all the samples collected per HOMA (Homogenous Area Material Sample) do not contain asbestos, then the HOMA is considered a non -ACM. However, if the analytical results of one or more of the samples collected per HOMA indicate that asbestos is present in quantities greater than one percent asbestos as defined by the EPA, all of the HOMA is considered to be ACM regardless of any other analytical results (unless a representative number of samples have been analyzed by PLM point counting, and indicate the material contains less than one percent asbestos). • All sampled material was non -detect for Asbestos fibers ACM Materials 16, Homogeneous area Sample Id Location Less than 1% ACM Materials Homogeneous area Sample Id Location Description Friable Asbestos Type Materi Description Friable Asbestos Type Material Type Pacific Northwest Inspections croup-425.608.9553 Page 4 of 5 148 165th Ave NE, Bellevue, WA 98008 1' N �►�I C�� Inspection Services Attachments Pacific Northwest Inspections Group - 425.608.9553 148 165th Ave NE, Bellevue, WA 98008 Page 5 of 5 SanATir Technologies Laboratory Analysis Report prepared for Pacific Northwest Report Date: 4/7/2021 The id 1 0 f M 1 0 o� Specialists Inspections Group Project Name: 21702 98th Avenue West Edmonds WA 98020 Project #: 21702 SanAir ID#: 21016051 V TESTING NVLAP LAB CODE 200870-0 Page 1 of 6 Air Technologies Laboratory Name: Pacific Northwest Inspections Group Address: 148 165th Ave NE Bellevue, WA 98008 Phone: 425-608-9553 Dear Darren Spencer, SanAir ID Number 21016051 FINAL REPORT 4/7/2021 2:38:09 PM Project Number: 21702 P.O.
