' Crawford,Murphy&Tilly William Street Pump Station,E.Main Street&S.29th Street, Decaur, IL October 6,2022/IDEAL Number 25115 General Comments Asbestos Survey Accessible building areas were visually inspected for suspect asbestos containing materials within the scope of this inspection. Materials suspected to contain asbestos are determined by EPA guidance materials, industry standards, and the inspector's experience and training. Suspect asbestos containing materials are generally any materials which are not metal, concrete, rubber,fiberglass, PVC, black foam glass,Armaflex, silicone or wood. However,the inspector ultimately determines what is suspected to contain asbestos, and, based on their own discretion, may include any of these materials in certain situations. A thorough inspection was completed, including,where applicable, checking above ceiling panels, behind walls, below carpet, etc.,to attempt to locate hidden materials.This was conducted within reason,within time constraints, in line with inspector safety and building occupancy constraints, and adhering to any desires of the client to avoid damage.Any suspect asbestos containing materials not found in the survey must be assumed to be ACM until sampled.Additional suspect asbestos containing materials may be found in pipe chases, hidden building cavities, behind walls, under floors, inside duct work, behind existing finishes or other similar areas. Materials may be misidentified if covered by paint,wallpaper,carpet, etc.The inspection ' did not include removal, dismantling or demolition of building components, unless otherwise noted. Unless specifically included in this report, mechanical equipment, electrical systems, elevators and confined spaces are excluded from the inspection.A return visit can always be requested for additional inspection service of opened wall cavities, discovered hidden spaces, HVAC systems, etc.,to access previously excluded areas. ' This survey was completed with generally accepted industry standard AHERA and/or NESHAP inspection practices within the constraints of the client's directive and time frame. EPA-NESHAP asbestos inspections are completed for compliance commonly associated with public and commercial buildings prior to renovation or demolition work.To help comply with the ' OSHA asbestos general industry standard 29 CFR 1910.1001 and the OSHA asbestos construction standard 29 CFR 1926.1101, the results of this report should be communicated to employees and other employers at the project site. For residences,the inspection was completed using NESHAP rules as guidelines. ' This inspection was prepared for the building owner or client as noted. If plans for the building change, additional inspection service may be necessary. It was not prepared for others.Any reliance on or use of this report by any third party is done at the risk of the third party. Reliance on this report by any third party does not make the third party a beneficiary to IDEAL's contract with the building owner or client as noted. ' The inspection was completed by EPA/AHERA-accredited, IDPH-licensed inspector(s)whose training is refreshed annually by an EPA-approved training course provider. Though thorough,the inspection is limited, as training is not guaranteed to encompass all clarifications, determinations, and amendments to regulations, nor is training guaranteed to cover all guidance publications. PLM is the standard analysis method specified in NESHAP and AHERA regulations for determining if a material is asbestos containing, and unless otherwise noted, it was used as the standard analysis method for this inspection. Unless otherwise noted,three(3)samples were collected per homogeneous building material, and this is the industry standard to determine if a material is asbestos containing.AHERA requires additional samples of surfacing materials based on the quantity of material. Based on established guidelines,the inspector determines how many samples are appropriate to achieve ' sufficient sampling for the quantity of each material present. Samples of friable materials are collected using random sampling. During random sampling, the Grid Method may not be used to avoid destructive sampling in visible areas. The inspector's determination of homogeneous areas and inferences for friability, damage condition,and whether a material is regulated, category I or category II are guided by regulations but remain subjective and may differ from another inspector. ' The inspection service excludes providing to any party suggested/required demolition contractor work practices, including but not limited to NESHAP and OSHA regulations. Sometimes, materials may appear to be homogeneous but may not be. While care has been taken to accurately determine ' homogeneous materials, installation dates may differ unbeknownst to the inspector, different product brands may have been used, or manufacturers may produce batches with different sources for raw materials. Determining homogeneity of drywall systems (i.e. drywall,joint compound,tape) is especially difficult due to possible multiple installations, renovations, repairs and since drywall systems are intentionally finished so these occurrences are not noticeable. In addition, replacement materials are ' often purchased to match original materials.When replacement materials are near-identical to original materials or if their presence is very localized or sporadic throughout,they may not be noted in this report. Inspectors generally check for underlying flooring materials at corners, seams,thresholds or damaged areas, and not all flooring is lifted. It is possible that multiple types of flooring are present under the accessible flooring if the top flooring is Ideal Environmental Engineering,Inc. (309)828-4259 www.idealenvironmental.com Page 115
