Durant, Aspen, CO 81611 Inspection Date: March 16, 2021 Phase Con Project #: 21-03-16D 2166 Peregrine Court RECEIVED Grand Junction, CO 81507 970-260-3341 -- office©phasecon.com 03/26/2021 ASPEN BUILDING DEPARTMENT 830 E. Durant Street, Aspen, Colorado Sampling Description Phase Con provided limited construction specific asbestos building inspection services at the property described above on March 16, 2021. The inspection was performed by Mr. Douglas Close, a Colorado State and EPA Asbestos Building Inspector/Management Planner. Building materials as indicated by the client as being impacted in the planned renovation work were the only building materials included within the scope of work (interior finish materials). Suspect materials within the scope of work were sampled and analyzed as per Colorado State Regulation #8. A random sampling scheme was utilized in choosing sampling locations. This scheme used a grid system and randomly generated numbers. The Inspector, Mr. Douglas Close, classified the suspect materials by type (Thermal System Insulation (TSI), Surfacing Materials, and Miscellaneous Materials), and obtained the appropriate number of samples of each material based upon material type, and quantity. Tables are provided which detail the individual samples obtained, the laboratory analysis results for these samples, the quantity and condition of ACBM, the locations of each homogeneous area, and other material specific information. Potential for damage to materials information is provided in the following sampling information tables. Discussion & Recommendations None of the tested building materials were found to contain asbestos in any quantity. If any previously unknown or undiscovered materials are found during demolition activities which are suspect for asbestos content then these materials should be tested for potential asbestos content prior to continuing any further demolition work. Disclaimer The inspection services process consists of initial inspection/sampling and sampling of subsequently discovered hidden or inaccessible building materials as the inspection/abatement/demolition process occurs withine-iCOVED rc 03/26/2021 ASPEN BUILDING DEPARTMENT the building. Discovery of hidden or inaccessible building materials by any interested parties can and will occur at any time during the inspection/abatement/demolition process and necessitates stopping demolition until the discovered materials can be properly inspected/sampled. The discovery of hidden materials during the building demolition process is common, should be expected by the client and is a normal part of the inspection process. Identified asbestos containing materials may be in areas which are inaccessible or hidden due to their application during the construction process and their subsequent enclosure or covering with building and finish materials. Areas behind walls, inside chases, or other hidden, covered or enclosed areas should be inspected whenever renovation or demolition activities are scheduled which may disturb the materials within or beneath these barriers. Care to watch for hidden or undiscovered materials should be taken by the demolition contractor during the demolition process. A discovery of unknown materials will necessitate stopping demolition until the materials can be inspected by a certified asbestos building inspector. 'Overspray' or excess materials from the installation or application process of asbestos containing materials is common, should be expected in the vicinity of installed asbestos containing materials, and is often present either covered by other building materials or in hidden or unexpected locations. Bulk material samples are obtained in accordance with applicable regulations, industry standard techniques and analyzed by a NVLAP accredited laboratory; however, due to the asbestos content fluctuations which may occur in a building material due to the application and/or initial mixing process no guarantee can be made as to an `exact' percentage asbestos content (this includes 'no asbestos detected' and 'trace' contents) which represents the entirety of the material (asbestos content fluctuations can and will occur throughout a building material). Abatement cost estimates and material quantity estimates are approximate only (due to the hidden nature of many of the materials), and are provided only as a general guideline to the client. More than one licensed Colorado State asbestos abatement contractor should be consulted to determine actual abatement costs of the ACBMs described above. Actual material quantities can only be determined by complete removal of covering materials. Please call us with any questions which you may have concerning this report and our recommendations.

The sample is first viewed with the aid of stereomicroscopy.Numerous liquid slide preparations are created for analysis under the polarized microscope where identifications and quantifications are preformed.Calibrated liquid refractive oils are used as liquid mouting medium.These oils are used for identification(dispersion staining).A calibrated visual estimation is reported,should any asbestiform mineral be present.Other techniques such as acid washing are used in conjugation with refractive oils for detection of smaller quantities of asbestos.All asbestos percentages are based on calibrated visual estimation traceable to NIST standards for regulated of asbestos.Traceability to measurement and calibration is achieved by using known amounts and types of asbestos from standards where analyst and laboratory accuracy are measured. As little as 0.001%asbestos can be detected in favorable samples,while detection in unfavorable samples may approach the detection limit of 0.50%(well above the laboratory definition of trace). Discussion Vermiculite containing samples may have trace amounts of actinolite-tremolite,where not found be PLM should be analyzed using TEM methods and/or water separation techniques.Suspected actinolite/vermiculite presence will be indicated through the sample comment section of this report. Fibrous talc containing samples may even contain a related asbestos fiber known as anthophyllite. Under certain conditions the same fiber may actually contain both talc and anthophyllite(a phenomenon called intergrowth).Again,TEM detection methods are recommended.CA Labs PLM report comments will denote suspected amounts of asbestiform anthophyllite with talc,where further analysis is recommended. Some samples(floor tiles,surfacings, etc.)may contain fibers too small to be detectable by PLM analysis and should be analyzed by TEM bulk protocols. A"trace asbestos"will be reported if the analyst observes far less than 1%asbestos.CA Labs defines"trace asbestos"as a few fibers detected by the analyst in several preparations and will indicate as such under these circumstances. Quantification of<1%will actually be reported as<=1%(allowable variance close to 1%is high).Such results are ideal for point counting,and the technique is mandatory for friable samples(NESHAP,Nov. 1990 and clarification letter 8 May 1991)under 1%percent asbestos and the"trace asbestos".In order to make all initial PLM reports issued from CA Labs NESHAP compliant,all<1%asbestos results(except floor tiles)will be point counted at no additional charge. Qualifications CA Labs is accredited by the National Voluntary Accreditation Program(NVLAP)for selected test methods for airborne fiber analysis(TEM),and for bulk asbestos fiber analysis(PLM).All analysts have a college degree in a natural science(geology,biology,or environmental science)or are recognized by a state professional board in one these disciplines.Extensive in-house training programs are used to augment education background of the analyst.The group leader of polarized light has received supplemental McCrone Research training for asbestos identification.This report is not covered by the scope of AIHA accreditation.Analysis performed at CA Labs,LLC 12232 Industriplex,Suite 32 Baton Rouge,LA 70809.
