The purpose of the inspection was to identify the presence of asbestos containing materials [ACM] throughout the structure prior to planned demolition of the structure. The structure is a one story, 3,500 square feet building. At the time of the inspection, the building was vacated in preparation for demolition. Additions/renovations have occurred on the structure, which in some cases have covered older building materials. The older building materials which may contain asbestos, may have been covered by subfloors and other building materials. Identifying, sampling, and determining actual extents of these older materials is difficult and creates a health hazard for the inspector. Materials identified during demolition activities that are not addressed in this report shall be considered ACM until sampled and analyzed by an accredited laboratory. The structure was visually inspected to identify building materials that may contain asbestos. Bulk samples were collected from suspect materials and analyzed to determine if they contain asbestos. 20 samples of suspect ACM were collected and analyzed by the accredited laboratory. Of those samples all were analyzed as "None Detected" for containing asbestos. All sampled building materials were analyzed to contain no detectable asbestos content. Included in the Appendix are the laboratory results. Introduction On June 2, 2023, Blake J Brown, a certified asbestos inspector under TSCA TITLE 11 at Idaho Abatement & Insulation Supply, LLC with accreditation certificate located in the Appendix, conducted an asbestos survey of the structure at Valley Ag. In Rexburg, Idaho identified for demolition. The purpose of this survey was to identify, to the extent feasible, the recognized asbestos containing materials that may exist within the structure while creating minor disturbance. Bulk samples collected were assessed for damage and friability. The building characteristics are listed below. The Warehouse structure, square footage is 3,500 sq ft. Wall types are concrete, roofing /siding is fiber board and tar paper and shingles. Foundation stem walls are concrete. Older buildings, like this structure, may have vermiculite fill insulation in sporadic areas of the ceiling that weren't identified during the inspection. Renovations have occurred to the structure, which in some cases have covered older building materials. The older building materials which may contain asbestos, may have been covered by subfloors and a health hazard for the inspector and for the workers/occupants. Any materials identified during future demolition activities that are not addressed in this report shall be considered ACM until sampled and analyzed by an accredited laboratory Survey Procedures Asbestos Survey The accessible areas of the structure were visually inspected to identify suspect ACM. All accessible surfaces and structures within these areas were examined and the suspected ACM was touched to determine friability. The suspect ACM was identified and assessed in homogenous areas. A homogenous area is defined as a single material, uniform in texture and appearance, installed at one time, and unlikely to consist of more than one type, or formulation, of material. Federal EPA's NESHAP and AHERA regulations define ACM as material containing more than 1% asbestos by weight, materials containing 1% or less asbestos are not considered regulated ACM. Bulk Sample Collection Twenty materials samples from the homogenous areas identified in the Survey Results section below were collected from the recognized areas of suspect ACM; all samples were submitted for laboratory analysis to determine asbestos content_ The laboratory results, sample location map, and photograph log in the Appendix identifies each sample collected, the room it was collected from and the composition of each sample. Sampling was conducted in a manner that was acceptable to the client. Bulk Sample Analysis Samples were analyzed by EMSL Analytical, Inc, 5950 Fairbanks North Houston Road, Housten, Texas 77040. The laboratory is accredited for the analysis of Industrial Hygiene and Environmental matrices by National Voluntary Laboratory Accreditation program [NVLAP]. All bulk samples were analyzed via Method EPA/600/R-93/116 using polarized light microscopy [PLM] and visual estimation. Survey Results Asbestos -Containing Materials Federal EPA's NESHAP and AHERA regulations define ACM as material containing greater than 1% asbestos by weight; materials containing 1% or less asbestos are not considered regulated ACM. 20 samples were collected from 20 identified homogenous areas suspected of ACM. *- NESHAP regulations allow forjoint compound to be combined into a composite material with drywall and tape. According to an EPA Notice of Clarification to the Final Rule titled "Asbestos NESHAP Clarification Regarding Analysis of Multi -Layered Systems' dated January 5, 1994, and included in the Appendix, "Where a demolition or renovation impacts such a wall system, a composite analysis of the wall system (percent of asbestos in the joint compound, tape and wallboard) should be conducted. If the analysis shows an asbestos content of greater than 1% and at least 160 square feet of wall system is involved in the demolition or renovation activities (whether planned or unplanned, during a calendar year), then activities would be subject to asbestos NESHAP. * Asbestos content in drywall composite samples for this project are all less than 1 percent asbestos in the drywall throughout the residence. Non -Asbestos Containing Materials Homogenous areas of suspect ACM are identified as Non -ACM if the laboratory analysis shows that material to contain less than 1% asbestos detected. The laboratory results, located in the Appendix, conclude that the following homogenous areas are non -ACM. Roof tar paper, concrete, caulking, fiber board siding, roof sealant, layers of shingles, and roof penetrations, shingles from smaller building, were all found to be none detected when analyzed by the laboratory. Suspect Materials Presumed to be Asbestos -Containing Materials without Laboratory Analysis The on -site material that was identified as suspect of being ACM and any unidentified building materials not described in this report shall be considered Asbestos Containing until tested for confirmation. Limitations and Exclusions of Warranty This asbestos survey and assessment was performed using procedures and a level of diligence typically exercised by professional consultants performing similar services. However, asbestos - containing material (ACM) can be present in the structure, but not identified using ordinary investigative procedures. No asbestos survey can eliminate uncertainty regarding the presence of ACM. Idaho Abatement & Insulation Supply, LLC's level of diligence and investigative procedures are intended to reduce, but not eliminate, potential uncertainty regarding the presence of ACM. The procedures used for this survey attempt to establish a balance between the competing goals of limiting conditions. Therefore, the determinations in this report should not be constructed as a guarantee that all ACM present in the subject property has been included in this report. This report presents Idaho Abatement & Insulation Supply, LLC's professional determinations, which are dependent upon information obtained during the performance of this survey. We take no responsibility for omissions or errors resulting from inaccurate information provided by sources outside of Idaho Abatement & Insulation LLC. No warranty or guarantee, expressed or implied, is made regarding the findings, conclusions, or recommendations contained in this report. The limitations presented above supersede the requirements or provisions of all other contracts or scopes of work, implied or otherwise except those stated or acknowledged herein. BlakeJ.
