1 May 3, 2018 Ms. Jessica Kenney Boulder Housing Partners 4800 Broadway Street Boulder, Colorado RE: Asbestos-Containing Building Materials Survey Glen Willow Pearl Street, Boulder, Colorado Farmer Project No Dear Ms. Kenney: Farmer Environmental Group, LLC (Farmer) performed the asbestos-containing building material survey of the Glen Willow Apartments (Site) located at Pearl Street, Boulder, Colorado for asbestos-containing building materials (ACBM) on April 26, Colorado Department of Public Health and Environment (CDPHE)-licensed Asbestos Inspector Jennifer Day (License #7191) conducted this survey under an agreement between Farmer and Boulder Housing. This inspection was conducted for the planned renovations at the apartments. The purpose of the survey was twofold: 1) determine locations and conditions of asbestos-containing products at the Site; and 2) assist in obtaining the necessary building permits with the State of Colorado in accordance with Colorado Regulation #8. The following non-friable asbestos products were identified at the site: Material Description Quantity Asbestos Content Location 4% Chrysotile - FT Throughout various 12 x12 Olive/Brown Floor Tile TBD* <1% to 5% Chrysotile - units, exposed and w/black Mastic Mastic under sheet vinyl Black Sink Undercoat 34 sinks 2% Chrysotile Kitchen The following friable asbestos products were identified at the site: Material Description Quantity Asbestos Content Location Orange Peel Texture on Drywall TBD* 2% Chrysotile Throughout walls and ceilings Throughout walls and Joint Compound TBD* 2% Chrysotile ceilings *TBD quantities to be determined based on if flooring to be removed or remain in place, and wall/ceiling to be disturbed through trade cuts.

2 Pearl Street, Boulder, Colorado Asbestos Report May 3, 2018 Page 2 All accessible areas within the Site were viewed and suspect materials touched by the inspector to determine the location, condition, and friability of observed asbestos material. All bulk samples were submitted for PLM analysis. When suspect material was initially sighted, bulk samples were usually collected. By definition, a homogeneous area means an area of surfacing material, thermal system insulation material, or miscellaneous material that is uniform in color and texture, and is installed within the same period. Farmer has had extensive experience with older buildings that have been abated during demolition or renovation projects. Occasionally, additional asbestos was discovered during demolition of concealing ceiling, wall, or flooring materials. Sample analysis reported as "" should be interpreted as meaning no asbestos was observed in the suspect material above the reliable limit of detection, (1% by visual estimation) for the PLM method. The following materials did not contain asbestos: Yellow/Brown Cove Base Mastic Clear/Green Vinyl Plank Glue White Caulk Drywall Cream 4 x4 Pattern Sheet Vinyl Clear Sheet Vinyl Glue Brown 2 x2 Stone Pattern Sheet Vinyl Tan/Gray Sheet Vinyl Tan Sheet Vinyl Cream 12 x12 Pattern Sheet Vinyl Beige 6 x6 Pattern Sheet Vinyl Yellow Mastic White Mastic Cream with Blue Sheet Vinyl Asphaltic Roof Shingle Any product containing more than 1% fibrous asbestos, when analyzed by PLM, is considered a potential hazard by the Environmental Protection Agency (EPA). PLM is the EPA-recognized method for determining fibrous bulk asbestos content. Additionally, the EPA indicates that further analysis by point counting be performed to confirm asbestos content for friable materials found to contain less than ten percent asbestos by visual area estimation. Point counting analysis may be omitted if the material is assumed to contain more than one percent asbestos and is then handled accordingly. All samples collected by Farmer were analyzed by J3 Resources, Inc.'s NVLAP-accredited and Colorado-licensed laboratory in Houston, Texas. Sample locations are presented in Appendix I. The PLM Report in Appendix II indicate the results of PLM analysis for bulk samples collected in the scheduled demolition areas. The PLM Report shows the room or area in which the sample was collected and provides a description of the sampled material. Based on observations made at the Site, and results of the analysis of bulk samples collected during the survey, Farmer recommends the following:

3 Pearl Street, Boulder, Colorado Asbestos Report May 3, 2018 Page 3 1. Additional samples should be taken of suspect materials not identified in this report. Not all units were inspected for this survey, therefore additional suspect materials may be present in units not observed (particularly flooring materials). 2. Asbestos materials that are not impacted by the renovation activities may remain in place. Trade cuts into walls will require abatement. Flooring replacement were the 12 x12 olive/brown floor tile is present will require abatement (if existing floor is removed and not overlain). If black floor tile mastic is disturbed it must be abated. If sinks are to be recycled, the mastic must be abated prior to recycling. 3. CDPHE dictates that only a licensed General Abatement Contractor (GAC) can remove, repair, enclose, or encapsulate asbestos-containing material. CDPHE further dictates that the asbestos abatement activity be designed and monitored by a licensed Asbestos Project Designer if area is greater than 3,000 square feet. 4. If ACBM are to be removed or disturbed as part of renovation/demolition activities the ACBM should be removed under abatement conditions before renovation begins. 5. According to Colorado Regulation #8, CDPHE must be notified for all demolitions of all facilities and all asbestos abatement projects that exceed the trigger levels, whatever is the lesser quantity. The notification requirements apply to both friable and non-friable asbestos materials. Notifications must be postmarked or delivered at least 10 working days before initiating abatement activities, and must be made using CDPHE forms. Forms can be obtained by contacting the CDPHE Asbestos Notification and Information Section at or online through the CDPHE website at 6. Collect additional bulk samples from previously concealed materials that may be revealed during demolition and/or remodeling activities, or from materials outside the original inspection scope of work. "Suspect" material includes any material serving as a sprayed-on or troweled-on acoustic or fireproofing surface; floor and ceiling tiles; transite panels, siding or shingles; thermal insulation or any material associated with mechanical systems; or any binding agent such as tar sealant, mastic adhesive, roofing tar, caulking, et cetera. Colorado Regulation #8 requires bulk samples in public buildings be collected by a licensed Asbestos Inspector or Inspector/Management Planner. 7. If any material cannot be positively identified as non-asbestos-containing by the analytical results of samples collected during this inspection, it should be treated as asbestos until a sample of the newly identified suspect material can be collected and analyzed by PLM. 8. To comply with National Emission Standards for Hazardous Air Pollutants (NESHAP) asbestos regulation (EPA 40 CFR 61, Subpart M), Farmer Environmental Group recommends removing all friable and non-friable ACBM that has the potential to become friable under abatement conditions prior to renovation or demolition activities. 9. The building/apartment owner should be aware that removing ACBM does not discharge ownership. During transport or after burial in an EPA-approved landfill, any contamination throughout the lifetime of the material remains the responsibility of the building/apartment owner.

4 Pearl Street, Boulder, Colorado Asbestos Report May 3, 2018 Page 4 Farmer has endeavored to inspect the existing conditions within the affected areas using CDPHE inspection protocols. Regardless of the thoroughness of a survey, it is possible that some areas containing asbestos were overlooked or inaccessible. This report presents general descriptions of various construction materials and the general locations where these materials were encountered. If questions arise during the planning for renovation, demolition or other construction, Farmer should be notified to permit us to review the situation and present recommendations. This report has been prepared on behalf of and exclusively for the use of Boulder Housing. The conclusions expressed by Farmer regarding the conditions of the site are based solely on the observations made on April 26, 2018, the data collected during this survey, and the laboratory results of the samples collected and analyzed. The beneficiaries are hereby advised that conditions observed are subject to change. This report and the findings contained herein shall not, in whole or in part, be disseminated or conveyed to any other party or be used or relied upon by any other party, in whole or in part, without Boulder Housing s or Farmer's prior written consent. Farmer appreciates this opportunity to provide asbestos consulting services to Boulder Housing. We have enjoyed working with you on this project and look forward to meeting your needs in the future.
