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. Table 1.0 Scope of Inspection Materials in RED are materials that contain greater than 1%asbestos or are assumed to contain >1%asbestos. Materials in GREEN contain less than 1% asbestos. Materials in BLACK do not contain asbestos.

04/10/2023 ASPEN BUILDING DEPARTMENT 4.0 Material Information A Homogeneous Area (HA) means an area of surfacing material, thermal system insulation material, or miscellaneous material that is uniform in color and texture. 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 (TSI): 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 (TSI): 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 RECEIVED 15 04/10/2023 ASPEN BUILDING DEPARTMENT • 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 Overspray 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." RECEIVED 16 04/10/2023 ASPEN BUILDING DEPARTMENT DS 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 identify multiple State of Colorado regulated materials that contain greater than 1% asbestos (ACMs), as well as multiple OSHA regulated materials that contain less than or equal to 1% asbestos. Professional abatement activities are required to remove or disturb the above- referenced asbestos-containing materials that contain greater than 1% asbestos. All activities impacting the materials that contain less than 1%asbestos are are regulated by OSHA. Please refer back to Section 4.6 of this report: Materials Containing 1%Asbestos or Less for additional information. 8.0 Asbestos Abatement & Demolition Requirements If ACM is to be removed or disturbed in a single-family residence, and the total quantity exceeds any of the regulatory trigger levels of 50 linear ft. on pipes, 32 ft2 on other surfaces, or the volume equivalent of a 55-gallon drum, a CDPHE-certified General Abatement Contractor (GAC) is required to perform the work. The regulatory trigger levels within a commercial building are 260 linear ft. on pipes, 160 ft2 on other surfaces, or the volume equivalent of a 55-gallon drum. In addition,formal notification to CDPHE prior to the abatement of ACM as well as air monitoring,visual inspections, and final air clearances by a CDPHE-certified Asbestos AMS is required. DS can provide the client or building owner with a proposal for project design, abatement oversight and air monitoring upon request. CDPHE regulations allow for the demolition of a building that contains certain non-friable asbestos-containing materials,such as caulking, tars, and mastics; however, demolition must be completed without causing the non- friable ACM to be rendered friable. Certain other non-friable materials, such as cementitious siding (Transite) and resilient floor tiles must be abated prior to demolition. DS recommends abating all ACM prior to abatement, regardless of friability. Burning a building with any ACM is prohibited. Operations such as sanding, cutting, crushing, grinding, pneumatic jacking, etc. of ACM are not permitted. Recycling of building materials such as concrete, metal, or wood that are bonded or contaminated with ACM, e.g. glue, caulking, or mastic is also prohibited. If any of the non-friable asbestos containing materials are to be recycled and rendered friable after demolition (i.e. crushing mastic-coated concrete), these materials must be abated of all ACM prior to shipping offsite for recycling. OSHA regulations regarding occupational exposure during demolition activities is still mandatory. OSHA 29 CFR 1926.1101 requires that workers performing construction-related activities be protected from asbestos fibers in excess of the permissible exposure limit of 0.1 f/cc of air. Contractors must comply with applicable provisons;; of OSHA 29 CFR 1926.1101 during demolition and renovation activities. These OSHA provisions include, but�are' O 17 04/10/2023 ASPEN BUILDING DEPARTMENT not limited to, PPE and respirators, personnel training, personal-exposure air monitoring, employee medical surveillance, wet removal methods, signage for regulated areas, etc. 9.0 Major Asbestos Spills If ACM is significantly damaged and the total quantity exceeds the regulatory trigger levels, the area is deemed a "Major Asbestos Spill." The area is consequently subject to the requirements in Reg. 8, Section III.T.2.—Major Asbestos Spills. Unless the entire facility is to be treated as a major asbestos spill, a Colorado-certified Air Monitoring Specialist (AMS) must determine the extent of the spill area. This may be done using visual examination, air samples, micro-vacuum dust samples, wipe samples or a combination thereof. If visible dust or debris is observed, directly related to or resulting from the known or assumed ACM which created the major asbestos spill, areas where it is observed must be included in the abatement of the spill. Samples must be collected and analyzed quantitatively by Transmission Electron Microscopy (TEM.) The General Abatement Contractor (GAC) selected to perform the cleanup of the spill must: • Submit notification in accordance with subsection III.E. (Notifications) or subsection III.G. (Permits), whichever is applicable to the Division for approval. • Using certified Workers and Supervisors, in accordance with Section II. (Certification Requirements), construct a containment in accordance with the requirements of the regulation. • HEPA vacuum then steam clean all carpets, drapes upholstery and other non-clothing fabrics in the contaminated area or discard these materials in accordance with subsection III.R. (Waste Handling) • Launder or discard all contaminated clothing in accordance with subsection III.R. (Waste Handling) • HEPA vacuum or wet wipe with clean amended water all hard surfaces in the contaminated area. • Discard all waste in accordance with subsection III.R. (Waste Handling) All persons must comply with any other measures, provided in writing by the Division, which are deemed necessary to protect public health. Following completion of Sections III.T.2.d.(i)through III.T.2.e.,the AMS must comply with air monitoring requirements as described in Section III.P. (Clearing Abatement Projects); air samples must be collected aggressively as described in 40 C.F.R. Part 763, Appendix A to Subpart E (EPA 2010), except that the air stream of the leaf blower must not be directed at any friable ACM that remains in the area. Gross removal of additional ACM may not be conducted under Section III.T.2. Any remaining gross removal of ACM must be abated in accordance with Section III.H. (Abatement Sequence). If additional ACM is to be removed, the final air sampling required in Section III.T.2.f. is not required to be conducted until after the additional removal is completed. 10.0 Project Design & Project Manager Requirements DS can provide an Asbestos Abatement Project Design as well as fulfill the Colorado Asbestos Abatement Project Manager requirements for any asbestos abatement project, as applicable below. Project Design An abatement Project Design is an accurate and detailed scope of work, which includes project specifications and procedures, containment design/equipment placement, and descriptions of engineering controls and work practices for an asbestos abatement project or response action that is required by CDPHE Regulation Number 8, Part B -Asbestos (Reg. 8) on large asbestos abatement projects. Prior to the start of any asbestos aba ,enrr)tr,_ project in a non-school building, where the amount of asbestos-containing material (ACM) to be`:remove L % disturbed exceeds 1,000 linear feet on pipes, or 3,000 square feet on surfaces, or in a school building in which 18 04/10/2023 ASPEN BUILDING DEPARTMENT the amount of friable ACM to be abated exceeds 3 linear feet on pipes, or 3 square feet on surfaces, a written Project Design must be developed by a State of Colorado certified Project Designer in accordance with subsection IV.G.7 of Regulation 8. A signed copy shall be posted on-site prior to commencing any abatement activities, shall be available on-site at all times, and shall remain onsite until final air clearances have been completed by a State of Colorado-certified Air Monitoring Specialist (AMS). Project Manager A Project Manager shall be used on all asbestos abatement projects in which the amount of friable asbestos- containing material to be abated exceeds 1,000 linear feet on pipes, or 3,000 square feet on other surfaces per CDPHE Regulation Number 8, Part B — Section III.B.6. An asbestos Project Manager on an abatement project shall be responsible for assessing that the project is conducted in accordance with Regulation 8, assessing that the Project Design is followed, assessing that the abatement project is cleared in accordance with Regulation 8, assessing that the asbestos waste generated on the project is properly manifested and disposed of in accordance with Regulation 8, and communicating these assessments to the building owner or GAC. Project Managers must have proof of Colorado certification as an asbestos Project Designer and Air Monitoring Specialist in accordance with Section II of CDPHE Regulation 8 as well as a minimum of one (1)year of experience supervising, overseeing or monitoring asbestos abatement projects.

600/R-93/116: Method for Asbestos in Bulk Building Materials, EPA -- 40 CFR Appendix E to Subpart E of Part 763, Interim Method for Asbestos in Bulk Insulation Samples General Notes • ND indicates no asbestos was detected; the method detection limit is 1 %. • Trace or "< 1" indicates asbestos was identified in the sample, but the concentration is less than 1% and cannot be quantified without point counting. • Samples identified as inhomogeneous (more than one layer) are separated into individual layers, and each layer is analyzed and reported separately. • All regulated asbestos minerals (i.e. chrysotile, amosite, crocidolite, anthophyllite, tremolite, and actinolite) were sought in every layer of each sample, but only those asbestos minerals detected are listed. Amosite is the common name for the asbestiform variety of the mineral grunerite. Crocidolite is the common name used for the asbestiform variety of the mineral riebeckite. • Tile, vinyl, foam, plastic, and fine powder samples may contain asbestos fibers of such small diameter (< 0.25 microns in diameter) that these fibers cannot be detected by PLM. For such samples, more sensitive analytical methods (e.g. TEM, SEM, and XRD) are recommended if greater certainty about asbestos content is required. Semi-quantitative bulk TEM floor tile analysis is accepted under NESHAP regulations. • These results are submitted pursuant to Aerobiology Laboratory Associates, Inc.'s current terms and conditions of sale, including the company's standard warranty and limitation of liability provisions. No responsibility or liability is assumed for the manner in which the results are used or interpreted. • Unless notified in writing to return the samples covered by this report, Aerobiology Laboratory Associates, Inc. will store the samples for a minimum period of thirty (30) days before discarding. A shipping and handling charge will be assessed for the return of any samples. • Aerobiology does not guarantee the results of tape lifts, microvacs, wipe, and/or debris samples. Accurate analysis cannot be performed due to particle size, media used, and/or amount of material given. Analysis of these materials should be preformed by a TEM. A result of ND does not indicate that the sample area does not contain asbestos. It means the analyst could not identify asbestos in the specific sample for the reasons listed above. Notes Required by NVLAP • This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the Federal Government. • This test report relates only to the items tested or calibrated. • This report is not valid unless it bears the name of a NVLAP-approved signatory. • Any reproduction of this document must include the entire document in order for the report to be valid.
