The purpose of the inspection was to determine if any of the materials that were damaged by a recent water loss or may be impacted by the restoration activities contain asbestos. 2.0 Limitations of Inspection This inspection was limited in its scope and only included specific areas and materials as defined by the client. The inspection did not constitute a full-building inspection and does not fulfill the asbestos inspection requirements for structures that are to be demolished. The table below, (Table 1.0), lists the suspect asbestos-containing materials included in the scope of the inspection. It identifies the specific areas that were included in the inspection as well descriptions of the suspect asbestos-containing materials in those areas that were sampled; or materials that were assumed to contain asbestos. The suspect asbestos-containing materials listed below may be found in other areas of the building that were outside of the scope of work for this inspection and sampling. Additionally, there may be other materials in other parts of the building that contain asbestos, which were not included in the scope of this inspection and sampling.

The asbestos content of the bulk-samples collected within a homogeneous area can be applied to the entire homogenous area, if they conform to the above characteristics and the regulated minimum sample quantities of each type of material have been collected and analyzed. An Asbestos Containing Material (ACM) is a material that contains more than 1% asbestos. Any material can be assumed to be an ACM, but not the contrary. 4.1 Material Friability A material can either be friable or non-friable. A friable material is one that, when dry, can be pulverized, or reduced to powder by hand pressure, a non-friable material cannot. A non-friable material may become friable if its condition had deteriorated or has been impacted by forces that have rendered it friable. 4.2 Material Classifications Sampled materials are divided into one of the following three categories: • Surfacing Material: sprayed or troweled onto structural building members • Thermal System Insulation (TS!}: any type of pipe, boiler, tank, or duct insulation • Miscellaneous Material: all other materials not classified in the above two categories 4.3 Material Conditions Sampled materials are placed into one of the following three categories of conditions: • Good: none to very little visible damage or deterioration • Damaged: the surface is crumbling, blistered, water-stained, gouged, marred or otherwise abraded over less than one-tenth of the surface if the damage is evenly distributed, or one-quarter if the damage is localized • Significantly Damaged: the surface is crumbling, blistered, water-stained, gouged, marred or otherwise abraded over greater than one-tenth of the surface if the damage is evenly distributed, or one-quarter if the damage is localized 4.4 Sample Quantities DS collected at least the minimum number of samples from each homogeneous area necessary to meet all regulatory requirements for the quantity of material to be disturbed in the scope of work as defined by the client. The quantities listed in this report are approximate and on-site verification of the exact quantity of each material is required for permitting, estimating and billing purposes. The following outlines the minimum sample quantities required per homogeneous area: • Surfacing Materials: up to 1,000 ft2 of material requires a minimum of three (3) samples; between 1,000 ft2 and 5,000 ft2 of material requires a minimum of five (5) samples; over 5,000 ft2 of material requires a minimum of seven (7) samples; one (1) sample of each patch • Thermal System Insulation (TS!}: each homogeneous area requires a minimum of three (3) samples; at least one (1) sample must be collected from each patch; and collect enough samples sufficient to adequately assess the material and determine the asbestos content for TSI fittings such as pipe elbows or T's, which a minimum of two (2) samples of each 7 • Miscellaneous Materials: collect enough samples sufficient to determine the asbestos content with a minimum of two (2) samples of each 4.5 Materials Reporting "TRACE" Results Any sample reporting a "TRACE" amount of asbestos shall be considered to contain greater than 1% asbestos unless it is further analyzed utilizing the point-count method and verified to be less than or equal to 1% asbestos content, and therefore not an ACM. TRACE does not mean it contains less than or equal to 1%. 4.6 Materials Containing 1% Asbestos or Less Materials containing less than or equal to 1% asbestos are not regulated by the Colorado Department of Public Health and Environment (CDPHE) Regulation 8, Part B -Asbestos. However, all demolition/abatement activities should be performed following the applicable Occupational Safety and Health Administration (OSHA) regulations. This includes, but is not limited to, the appropriate asbestos training for the type of material being removed/disturbed as well as having a properly trained supervisor onsite, using wet removal methods, wearing adequate personal protective equipment (HEPA-filtered particulate respirators), medical surveillance of workers, personal-exposure air monitoring, area air monitoring in occupied buildings, etc. There may also be landfill disposal requirements for these materials, depending on the facility. DS recommends that all demolition/renovation projects involving the disturbance of any amount of asbestos be subjected to post- work visual inspections and a final clearance air testing by a CDPHE-certified Asbestos Air Monitoring Specialist (AMS) after the work has been completed, but before any containments are dismantled, the contractor demobilizes, and the area is reoccupied. 4. 7 Overs pray Any surfacing material indicated in this report also includes any associated overspray of that material, e.g., under carpet, above suspended ceilings, on studs and structural members, etc. 5.0 Inspector & Firm Certifications The inspection detailed within this report was conducted by Mr. Chris Lehman with DS. DS is a CDPHE certified Asbestos Consulting Firm, Registration No. 14912. Mr. Lehman is a CDPHE certified Building Inspector; having certification number 14348 (see Appendix A for certificates). 6.0 Inspection, Sampling & Analytical Procedures 6.1 Inspection Procedures The asbestos inspection detailed in this report was conducted by an Environmental Protection Agency (EPA) and CDPHE certified asbestos Building Inspector. The inspection procedures included identifying and sampling suspect ACM within the pre-defined areas that were within the scope of work, submitting samples to an accredited laboratory for analysis, classifying the materials and assessing their condition, and compiling a final report detailing the inspection and the analytical results of the bulk-samples. 6.2 Sampling Procedures Statistically random bulk-samples representative of the suspect ACM of each homogeneous area were collected according to the guidelines published in the Environmental Protection Agency's October 1985 publication, "Asbestos in Building: Simplified Sampling Scheme for Friable Surfacing Materials", commonly known as the "Pink Book." 8 OS has collected the appropriate number of bulk-samples to meet all regulatory requirements for the classification and quantity of each homogeneous area. All reasonable efforts were made to identify homogeneous areas and to sample or assume suspect materials. Destructive investigation was conducted whenever feasible, and every effort was made to locate and quantify suspect ACM within the scope of work. Any material not identified and sampled in this report shall be assumed to be an ACM or shall be sampled by an EPA-trained and CDPHE-certified inspector and submitted for analysis. 6.3 Analytical Procedures All asbestos bulk-samples were analyzed by a third party, National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory via Polarized Light Microscopy (PLM) for asbestos content per CDPHE Regulation 8 (see Appendix B for laboratory report). 7 .0 Recommendations The asbestos inspection detailed in this report did not identify ACM(s); therefore, no professional abatement activities are required to remove or disturb the above-referenced sampled materials. 8.0 Disclaimer & Limitations The activities outlined in this report were conducted in a manner consistent with a level of care and expertise exercised by members of the environmental consulting and industrial hygiene profession. All activities were performed in accordance with all applicable federal, state, and local regulations as well as generally accepted standards and professional practice. No warranty is either expressed or implied. OS assumes no responsibility or liability for error in public information utilized, statements from sources other than OS, or developments resulting from situations outside the scope of work for this project. The details provided within this report outline the inspection activities on the date(s) indicated and should not be relied upon to represent conditions at a later date. The laboratory results contained in this report apply specifically to the materials in which bulk-samples were collected. The results do not include or apply to any other materials within the structure that were not sampled but may contain asbestos; including materials that may be hidden or inaccessible. Additional inspection and bulk-sampling activities by a certified inspector would be required to determine whether any other materials contain asbestos. This report has been prepared on behalf of and exclusively for use by the OS's client, with specific application to their project as discussed in the scope of work. The information contained in this report is intended as supplementary material for abatement design and is not to be used as the sole means to develop the scope of abatement activities, bidding or billing purposes.
