5 Section 2 Results and Recommendations The damage or disturbance of confirmed asbestos-containing building materials has resulted in an asbestos fiber release episode. Greater than the established trigger level quantity of asbestos-containing building materials have been damaged or disturbed resulting in a major asbestos spill at the Site Address (see section 3 for additional information). The entire inside of the home must be contained and decontaminated by a certified and licensed asbestos abatement contractor. See Appendix B for required asbestos spill response actions. Additional dust or air sampling is required to delineate the extent of the spill and possibly reduce the abatement scope of work. All contents in a contaminated room/area must be considered as contaminated unless proper dust or air sampling verifies the area to be free of asbestos. Any work performed on asbestos-containing building materials and/or trace asbestos-containing building materials is subject to OSHA regulations, including but not limited to: hazard communication, asbestos construction industry, general construction industry, and respiratory protection standards. Worker exposure assessments are part of the asbestos construction industry standard and include excursion limits and 8-hour time-weighted permissible exposure limits which, if exceeded, may require additional engineering or administrative controls to properly protect workers engaged in activities that may damage or disturb materials which contain asbestos. Asbestos-containing building materials have been identified within the affected area(s) of the Site Address. Any repair, removal or other activities that will disturb asbestos-containing materials must be performed by a certified and licensed asbestos abatement contractor in accordance with applicable federal, state, and local regulations. Any friable suspect asbestos-containing materials identified as having trace ( 1%) asbestos through laboratory visual estimation must be considered to be an asbestos-containing building material. Further analysis may be performed on friable materials having a visual estimate of 1% by point counting, which is a more quantitative analysis of the material. Any work performed on asbestos-containing building materials and/or trace asbestos-containing building materials is subject to OSHA regulations, including but not limited to: hazard communication, asbestos construction industry, general construction industry, and respiratory protection standards. Worker exposure assessments are part of the asbestos construction industry standard and include excursion limits and 8-hour time-weighted permissible exposure limits which, if exceeded, may require additional engineering or administrative controls to properly protect workers engaged in activities that may damage or disturb materials which contain asbestos.

6 2.1 Post-Renovation Asbestos Containing Materials Notice Plans for renovation were not known at time of inspection. Please assume ACBM(s) identified in this report are accessible with the potential for disturbance and/or damage from material contact, vibration and/or air erosion. CDPHE requests that the Client notify the current property owner and all site contractors of the ACBM(s) present at the property. 2.2 Photo Log of Asbestos Containing Materials Contaminated areas include: The entire inside of the home must be considered a major spill until spill delineation has been performed as all areas of the home are open to the area of disturbance. The following material(s) contain(s) greater than 1% asbestos: The white remnant texture on the ceiling of the kitchen.

7 Section 3 Project Overview BuildSafe Environmental, Ltd. (BuildSafe) was contracted by the client to perform a limited repair/renovation specific asbestos inspection (inspection) at the above referenced Site Address. The inspection was conducted by an Environmental Protection Agency (EPA) accredited and Colorado Department of Public Health and Environment (CDPHE) certified Asbestos Building Inspector. The inspection was performed at the direction of the client and only includes those materials, locations, and quantities specified in the Homogenous Areas in Work Scope Table. The client is planning repair/renovation activities that will disturb suspect Asbestos Containing Building Materials (ACBM) within the repair/renovation affected areas at the Site Address. CDPHE Air Quality Control Commission Regulation No. 8, Part B Asbestos (Reg 8) requires that all suspect ACBMs be properly inspected and sampled by certified personnel prior to conducting any repair/renovation activities that will disturb the suspect ACBMs. All samples were analyzed by a laboratory accredited under the National Voluntary Laboratory Accreditation Program (NVLAP). The CDHPE has established the following trigger levels for different types of properties, which specify how suspect and confirmed ACBMs are inspected and subsequently abated: With regard to single-family residential dwellings (SFRD), the trigger levels are 50 LF on pipes, 32 SF on other surfaces, or the volume equivalent of a 55-gallon drum With regard to all areas other than SFRDs, the trigger levels are 260 LF on pipes, 160 SF on other surfaces, or the volume equivalent of a 55-gallon drum The purpose of the inspection was to identify, visually inspect, and sample all suspect ACBMs, at the direction of the client, which may be disturbed during the course of the repair/renovation work.

8 Section 4 Asbestos Inspection Procedure The inspection procedure was conducted in accordance with EPA Asbestos Hazard and Emergency Response Act (AHERA), the EPA Pink Book, CDPHE Reg 8, and applicable Occupational Safety and Health Administration (OSHA) guidelines and regulations. These regulations specify requirements and protocols for conducting asbestos inspections, sample analysis, and asbestos abatement. 4.1 Suspect Asbestos Containing Building Materials Homogenous Material Types The inspection involved identification and sampling of suspect ACBMs in the areas established by the client that would be part of the scope of work. Suspect ACBMs were grouped into homogenous materials based on color, texture, and date of application. Homogenous materials were given distinct codes (CDW01, FTC02, TS05, etc.) based on the type sequence of the homogenous material. Details about the size, color, condition, friability, quantity, location within each functional space and other important details for each homogenous material were reported as part of the inspection. Homogenous materials are grouped into one of three categories based on intended use: 1. Surfacing Material material 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. 2. Thermal System Insulation material applied to pipes, fittings, boilers, breeching, tanks, ducts, or other interior structural components to prevent heat loss or gain, or water condensation, or for other purposes. 3. Miscellaneous Materials 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.

9 Homogenous Material Friability Each homogenous material was given one of the three following friability categories defined by the EPA and CDPHE: 1. Friable Material materials that can be crumbled or reduced to powder by hand pressure. 2. Category I Non-friable Material materials that cannot be crumbled or reduced to powder by hand pressure including resilient floor coverings, gaskets, packing materials and asphalt impregnated roofing materials. 3. Category II Non-friable Materials all other materials that cannot be crumbled or reduced to powder by hand pressure that do not include category I non-friable materials. Homogenous Material Condition Each homogenous material was given one of three condition categories based on visual observation defined by the EPA and CDPHE: 1. Good Condition No visible signs of damage were observed during the inspection. 2. Damaged Condition Visible signs of damage less than ten percent spread over the entire material or twenty five percent localized. 3. Significantly Damaged Condition Severe damage greater than ten percent spread over the entire material or twenty five percent localized. 4.2 Sampling and Laboratory Analysis Sample Collection Bulk samples of each suspect homogenous material were collected randomly throughout the homogenous material area within the scope of work. Bulk samples were sampled all of the way through the material so that all associated layers within each homogenous material are represented. Bulk samples were placed in closeable sample bags and then labeled with a permanent marker with distinct sample identifiers (e.g., CDW1-1, FTC2-1, MISC2-3, etc.) for transport to the laboratory. Sample locations and photographs of the

10 homogenous materials were also collected at this time during the inspection. Sample quantities of each homogenous material were collected based on material type and quantity detailed in the following table as required by regulation: Homogenous Material Minimum Number of Quantity Type Samples Surfacing material 0 to <1,000 SF 1,000 to 5,000 SF >5,000 SF Thermal System Insulation Each Material 3 Patch < 6 LF, SF 1 Miscellaneous Material Each Material 1 Laboratory Sample Analysis Bulk samples were submitted to the laboratory along with a completed chain of custody form to the above listed NVLAP accredited laboratory for analysis by polarized light microscopy (PLM) techniques per EPA methodology (EPA-600/M , Dec. 1982). Microscopic visual estimation was used in obtaining the percentage of asbestos within each layer of the bulk samples. Asbestos Containing Building Materials EPA and CDPHE both define an asbestos containing building material (ACBM) as a material which has an asbestos content of greater than one percent. In the event that a friable material is estimated to contain trace or between zero-to-one percent, that material must undergo a point-count analysis by the laboratory to confirm that the material is trace asbestos-containing. Further, if a point count analysis is performed on a bulk sample, the point count result takes precedence over the visual estimation result. See appendix A for laboratory report and chain of custody documents.

11 Section 5 Conclusion BuildSafe has performed a limited repair/renovation specific asbestos inspection of the home/facility located at the Site Address. Through visual inspection and laboratory analysis of bulk samples collected at the Site Address, BuildSafe recommends hiring a certified general asbestos abatement contractor to remove any ACBMs that may have been identified within the scope of work. All inspection activities were conducted at the direction of the client and only include those materials, quantities and locations detailed in sections 1 and 2 of this report. See sections 1 and 2 of this report for information regarding inspection scope of work, suspect ACBMs, confirmed ACBMs, sample information and laboratory analysis results. 5.1 Limitations General Comments and Limitations Reasonable effort was made by BuildSafe to locate and sample accessible suspect ACBMs within the scope of work. However, for any structure, the existence of unique or concealed suspect ACBMs is a strong possibility. BuildSafe only inspected and collected suspect ACBM bulk samples in the repair/renovation areas at the direction of the client. This limited repair/renovation asbestos inspection report is not considered a comprehensive asbestos inspection report and is only valid for the materials and locations detailed in sections 1 and 2 of this report. Should further repair/renovation work expand outside of materials and locations listed in sections 1 and 2 of this report, those locations must be properly inspected and sampled by qualified personnel prior to disturbance of suspect ACBMs. Any subsequent abatement of ACBMs must be performed in accordance with all federal, state and local regulations pertaining to abatement, transport, and disposal of ACBMs.

12 The asbestos inspection was conducted in a manner consistent with the level of care and skill exercised by professionals of the asbestos inspection profession. The results, findings, conclusions and recommendations expressed in this report are based on conditions observed during our limited inspection of the repair/renovation areas. The information contained in this report is relevant to the date on which this survey was performed, and should not be relied upon to represent conditions at a later date. This report has been prepared on behalf of and exclusively for use by the client for specific application to the project as discussed. Contractors or consultants reviewing this report must draw their own conclusions regarding further investigation or remediation deemed necessary. BuildSafe does not warrant the work of regulatory agencies, laboratories or other third-parties supplying information which may have been used in the preparation of this report. No warranty, express or implied is made. Sincerely, Blake Weise BuildSafe Environmental, LTD 303 S Broadway, Unit Denver, CO Blake@BuildSafeEnviro.com
