CONCLUSIONS AND RECOMMENDATIONS LIST OF APPENDICES APPENDIX A - SAMPLE INVENTORY LIST & LAB ANALYSIS APPENDIX B - INSPECTOR LICENSE AND CERTIFICATION APPENDIX C - PICTURES SECTION 1 INTRODUCTION For each area of the building, the inspector performing the inspection did the following: 1. Visually inspected the area(s) to identify the locations of all suspect Asbestos Containing Building Materials. 2. Identify all homogeneous areas of friable and non -friable suspected asbestos. 3. Assume, if necessary, that some or all of the homogeneous area(s) are Asbestos Containing Material (ACM), and for each homogeneous area that is not assumed to be ACM, collect and submit bulk samples for analysis. SECTION 2 DEFINITIONS: HOMOGENEOUS AREA An area which appears similar throughout in terms of color, texture, and date of material application. SURFACING MATERIAL Material in a building that is sprayed -on, troweled -on, or otherwise applied to surfaces, such as acoustical plaster on ceilings and fireproofing materials on structural members, or other materials on surfaces for acoustical, fireproofing, or other purposes. THERMAL SYSTEM INSULATION Means material applied to pipes, fittings, boilers breeching, tanks ducts, or other interior structural components to prevent heat Toss or gain, or water condensation, or other purposes. MISCELLANEOUS MATERIAL Interior building material on structural components, structural members or fixtures, such as floor and ceiling tiles, and does not include surfacing material or thermal system insulation. SAMPLING AND ANALYSIS All samples to be analyzed by Polarized Light Microscopy (PLM). Analysis was performed in accordance with EPA 40 CFR, Part 763, Appendix A to Subpart F. A homogeneous area was considered not to contain Asbestos Containing Material (ACM) only if the results of all samples collected from the area showed asbestos in the amounts of one (I) percent (%) or less L1%). A homogeneous area contains ACM when one or more samples collected from that area shows greater than one (1) percent (%) asbestos (> 1 %). FRIABLE Any material containing more than one (1) percent (%) asbestos that, when dry can be crumbled, pulverized, or reduced to a powder by hand pressure. NON -FRIABLE (CATEGORY I) Asbestos containing packings, gaskets, resilient floor covering, and asphalt roofing products, containing more than one (1) percent (%) asbestos. NON -FRIABLE (CATEGORY II) Any excluding Non -Friable (Category I) Asbestos Containing Material, containing more than one (1) percent (%) asbestos. SECTION 3 General Building Inspection Observations The building inspection is conducted by a qualified and State of Iowa licensed Asbestos Inspector. The purpose of a building inspection is to identify existing building materials that are asbestos containing materials (ACM). If the inspection is conducted in an occupied building, the Inspector is sometimes denied accessibility to building areas and materials; i.e., the Inspector may not be allowed to cut through floor coverings or walls, remove quarry tiles, etc. There are many situations where ACM are concealed in wall cavities and other non -accessible areas, such as tunnels, crawl spaces, above ceilings, pipe chases, behind wall coverings, beneath debris piles, under various floor coverings, etc. When these situations occur in construction, renovation, and/or demolition, etc., materials in these areas shall be treated as ACM and handled as such by qualified and licensed asbestos personnel. If suspect asbestos containing material is discovered or damaged during the course of any activities, the material shall be considered and treated as ACM to diminish further fiber release. In addition, the Inspector uses an independent laboratory that analyzes the bulk building material samples using Polarized Light Microscopy (PLM). PLM analysis technique may not be as accurate as more expensive analysis techniques for certain building materials. It remains the Building Owner and/or Representative(s)' responsibility to address this issue and consider analyzing suspect building material using different analysis techniques prior to disturbing the material(s). The following are areas that may not be inspected. 1. Tunnels and Crawl Spaces: During the inspection process, the Inspector attempts to check tunnels and crawl spaces for ACM and the degree of damage to the materials. In most cases, quantification of ACM in these areas is impossible due to the inaccessibility to these areas. In addition, these areas may fall under: "Confined Space Regulations". Due to the congestion in tunnels and crawl spaces, obtaining an accurate quantification for mudded joints, pipe wrap, etc. is almost impossible. The Inspector will quantify ACM only in accessible tunnels and crawl spaces, and estimate the quantities in the inaccessible areas. Some reasons for inaccessibility are as follows: flooded areas, pipe congestion, asbestos and other debris, electrical hazards, confined spaces, unknown gas emissions, low ceilings, etc. 2. Boilers and Thermal System Insulation: Interior portions of boilers, heaters, storage tanks, etc. are not always accessible. Materials in these areas will be treated as ACM. Areas of concern are packing inside boiler doors and liners. Use extreme care and properly trained personnel when handling these types of materials. Some boilers have insulated metal jackets over fiberglass or ACM. Thermal system insulation can be found in many different forms; i.e., air cell, preformed magnesium block, miliboard, etc. All fiberglass materials are excluded as suspect ACM. 3. Debris: In areas where damaged ACM may be found there may and usually will be ACM debris in the general area of the damaged material. These areas shall be treated with the utmost care even during the inspection and quantification process. The Inspector considers any exposure to this type of material as a health threat. 4. State of Quantification: As a general rule, individual rooms or areas of estimation contain inherently more probability of an error than those groups of rooms or areas or an entire building. In other words, the aggregate tends to be more accurate than the sums of the individual parts. Therefore, when designing response actions (measurements, air samples, etc.), the project designer and the asbestos abatement contractor's attention shall be given to ensure that quantification of materials and proper methods are followed through careful analysis of the site. If materials are quantified, the asbestos abatement contractor or owner, owner representatives or third parties are responsible for verifying the quantities. 5. The Inspector may take some latitude in the presentation of the Inspection Report. When the Inspector has found floor tiles, linoleum, and/or carpeting listed he/she may or may not have adhesives listed. Adhesives have been known to contain asbestos and therefore, although not mentioned, it may be presumed to be ACM, listed or not. Testing of the adhesive prior to disturbing is recommended. The same is true for adhesives or mastics used to adhere linoleum to floors or counter tops. All toweled -on and/or sprayed -on surfacing materials; i.e., floor mastics, wall and ceiling surfacing, etc. are either suspected or presumed ACM unless sampled and analyzed to indicate that they are not ACM. b. In the Inspection Report, certain items such as mudded joints (MJ) or metal doors (MD), etc. are listed as units or number of units; i.e. 10 MJ, 3 Damaged, which is an indication of count rather than square feet or linear feet. Most materials listed in the assessment are either listed as square feet or linear feet with these noted exceptions. 7. In the Assessment Process, there are additional codes such as ME and MG; ME representing miscellaneous electrical and MG representing miscellaneous gasket materials. Both of these codes are used to indicate materials that are unusual to the normal course of an assessment of the building. Miscellaneous electrical materials include old electrical wiring, switchboards, transite panels, etc. Miscellaneous gasket materials can be found between (thermal) valves, on boiler doors, between fittings, between molds, etc. These codes give the Inspector the ability to qualify materials, which sometimes may not be considered as ACM. 8. An Asbestos Code Sheet is included with the Inspector's inspection report, which informs the client as to the Homogeneous Codes used during the inspection process. 9. Caution- Regarding Inspection results- Floor tiles, adhesives, and drywall (mud) found to not contain asbestos should be re -analyzed under the "Chatfield Method" of TEM analysis. Many times the results from having these materials analyzed under PLM results in false positives or false negatives. After reviewing your report, please notify the inspector if you want these samples analyzed under the "Chatfield Method". 10. Any sample less than 10% asbestos may be Point Counted. Point counting is a more accurate method of analyzing of bulk samples. The results of the point counting are the results that will determine if the material will be treated as asbestos. 11. Asbestos inspections are performed based on current understanding of the regulations. As new interpretations of the regulations are made aware of by the EPA, DNR, and Iowa Division of Labor. Advanced Environmental Testing and Abatement Inc. will adapt their inspections to comply with these new procedures. If additional sampling is required by the different agencies, Advanced Environmental will do the additional sampling. The owner is responsible for the additional cost for these samples as well as labor. 12. Advanced Environmental shall not be responsible for any cost of abating any additional asbestos discovered in any renovation or demolition activities. Any additional items discovered shall be tested when they become accessible. For example, old adhesive may be under new floor tiles and adhesive. Additional materials may be concealed in walls, under multi layers of flooring, etc. 13. All amounts listed are estimates. It is up to other contractors to field verify any amounts that are listed within this report. 14. All material that looks similar should be treated as asbestos containing materials. 15. Asbestos Material containing <1%. Some material tested for asbestos may contain trace amounts of asbestos and be below the threshold for asbestos contain material according to both the Iowa DNR and Iowa State Code.. However, the Federal Occupational Safety and Health Administration still have some regulations that contractors must follow under 29 CFR 1926.1101. Contractors working with asbestos material with <1% asbestos must still produce a negative and initial exposure assessment, completed by a "competent person". Contractors must follow 29 CFR 1926. 1101 (g)(1)(ii) and (iii) and 29 CFR 1926. 1101(g)(3)(i), (ii), and (iv). Please contact Advanced Environmental Testing and Abatement, Inc. for consultation on how to handle material with <1% asbestos. 16. Flat roofs: If any layer of a flat roof tests positive for asbestos, all layers should be considered asbestos and removed as such. Advanced Environmental makes every effort to core roof samples through all layers.

SECTION 4 REPORT DATA BUILDING NAME: Titus Lift Station — 2295 WCF & N Drive — Waterloo, IA INSPECTION AREAS: Throughout CLIENT CONTRACT: Brad Oja METHOD: All samples are sent to EMC LABS, INC in Phoenix, Arizona. EMC LABS is accredited by the National Institute for Standards and Technology for Polarized Light Microscopy analysis under their NVLAP accreditation (NVLAP #: 101926-0). Sampling was completed by a State of Iowa licensed asbestos inspector. Sampling methods were based on National Emission Standards for Hazardous Air Pollutants (NESHAPS) protocols. Bulk samples of suspect asbestos containing material were analyzed by Polarized Light Microscopy (PLM) using EPA Method 600-R93-116. OVERVIEW: An asbestos inspection was conducted at the lift station located at 2295 WCF & N Dr. in Waterloo, IA on October 16th, 2024. The building is a small concrete building. At the time of inspection, a total of six samples were analyzed with eight layers analyzed for asbestos content. Each sample is broken down by layers if necessary (I.e. floor tile and mastic). Samples can be categorized by miscellaneous, surfacing, and thermal. The following samples were taken of each: Miscellaneous samples tested include: Roof seam tar Seam Caulk Pipe putty in opening Concrete/caulk Surfacing samples include: NO SAMPLES TAKEN Thermal samples include: NO SAMPLES TAKEN SECTION 5 POSITIVE SAMPLE RESULTS: The following samples tested positive (>1%) for asbestos: 3) White seam caulk (under silicone) 7% Chrysotile The inspection was to identify asbestos containing materials prior to demolition The Inspection entailed a visual assessment of the property for suspect asbestos containing materials, collection, and submittal of bulk samples for analysis. In the State of Iowa, asbestos is regulated by the Iowa Department of Natural Resources and the Iowa Division of Labor. CONCLUSIONS AND RECOMMENDATIONS I thought I was sampling the silicone caulk at the top of the wall where the wall meets the concrete roof. Apparently, there was white caulk under the silicone caulk that came back with 7% Chrysotile. This material will need to be removed prior to demolition Pictures of all these items are included at the back of the report.
