(RMC) performed a Limited Phase II Environmental Site Assessment (ESA) for the commercial property located at 5725 West 38th Avenue in Wheat Ridge, Colorado in general accordance with our contract (RFP No. RFP-13-11) and the guidelines set forth under American Society for Testing and Materials (ASTM) E 1903-11, Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process. The Limited Phase II ESA was prepared for the City of Wheat Ridge, as a part of the Community-Wide Brownfields Assessment Project to assess properties within the City’s identified redevelopment areas that have, or are perceived to have, environmental concerns related to previous uses or the age of the buildings on site. This Phase II ESA further assesses the recognized environmental concerns (RECs) identified in connection with the subject property by the Phase I ESA completed by RMC in December 2015 (RMC, 2015) and determines whether potential site contamination caused by current or previous use of the property and adjoining properties exists. Field investigation activities were completed in February 2016. A summary of the findings of the Limited Phase II ESA is provided below. Details of the subject properties assessment has not been included or fully developed in this summary, and the report must be read in its entirety for a comprehensive understanding of the items contained herein. This report is for informational purposes only, is limited in scope due to residence occupancy at the time of inspections, and is not intended to be used as a bid document for removal, repair, encapsulation, enclosure, or operation and maintenance of asbestos containing materials. The limited subsurface soil and groundwater investigation at the 5725 West 38th Avenue subject property did not identify site contamination that may present a threat to human health or the environment. No contaminants were detected in the soil or groundwater samples. The few contaminants detected in the soil vapor samples were not associated with dry cleaning facilities or automotive repair, and their concentrations were far below their EPA screening values, except for two analytes. The 1,3 butadiene concentrations detected above the screening level appear to be associated with vehicle exhaust or other atmospheric pollutants, and the benzyl chloride concentrations may be from industrial chemical manufacturing of plasticizers, flavorants, and perfumes, and the synthesis of amphetamine-class drugs. However, their presence in the soil gas, at concentrations above the EPA screening levels, necessitates considerations for the current and future uses of the subject property. Indoor air quality should be tested in any buildings that will remain occupied or in any new construction that will be occupied. With new construction on the subject property, vapor barriers and remediation systems should be considered in the building design, rather than the more expensive retrofitting. The asbestos containing material (ACM) sampling was limited in scope due to the fact that the residence is currently occupied. No destructive sampling was performed to avoid or render suspect materials friable as a result of sample collection. Only readily accessible areas associated with the buildings were inspected for ACM. Inspection of underground conduit, electrical panels, electrical wire insulation, instruments or other appurtenances were not performed. Asbestos was found in a number of areas of the buildings in several types of building materials. Both friable and non-friable ACM was identified. The following sampled materials contain greater than one percent (1%) asbestos:  The friable felt backing on Vinyl Sheet Flooring (VSF) materials located in the residence.  The floor tile material located in the basement of the residence. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado v  The paper duct tape materials located on air ducts, and wall heat registers located in the residence.  The joint compound associated with the non-asbestos containing drywall panels located in the northwest bedroom of the residence.  The joint compound associated with the non-asbestos containing drywall panels located in the middle room of the Coop building. Removal, in accordance with the Colorado Department of Public Health and Environment’s Regulation No. 8, is required because the amount of asbestos-containing material that is friable or will be made friable during renovation or demolition activities exceeds the trigger levels. Requirements set forth in the Occupational Safety and Health Administration’s Construction Asbestos Standard, 29 CFR 1926.1101 must also be followed when handling asbestos containing material. The vault containing the domestic well and its appurtenances should, at a minimum, be covered with sturdy materials (i.e., lid and lid supports) to prevent persons from falling through the rotted vault cover. The well should be properly maintained or abandoned according to the rules and regulations of the State Engineer’s Office (see 2 Code of Colorado Regulations [CCR] 402-2). The well is a direct conduit from the ground surface to the water table that presents a potential pathway for any contamination to adversely affect groundwater quality. A licensed well driller should properly abandon this well if it is to remain unused. Findings of the Phase II investigation indicate the presence of hazardous substances (i.e., asbestos and two soil vapor compounds) at the site. Furthermore, there appears to be a low potential threat to human health (e.g., asbestos and soil vapor) and safety (e.g., well vault) when redeveloping the property. However, the risks can be mitigated. Findings from the investigative activities conducted as part of this Limited Phase II ESA do not warrant additional Phase II ESA investigations, nor does this subject property require a voluntary clean-up effort. However, the indoor air quality, asbestos containing materials, and the domestic well vault should be addressed as described above. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 1 1 Introduction RMC Consultants, Inc. (RMC) completed a Limited Phase II Environmental Site Assessment (ESA) for a site specific small commercial property located at 5725 West 38th Avenue in Wheat Ridge, Jefferson County, Colorado, hereinafter also referred to as the “subject property” (Figure 1). Limited Phase II ESA work was recommended for the subject property based on the presence of recognized environmental concerns (RECs) identified in connection with the subject property by the Limited Phase I ESA completed by RMC in December 2015 (RMC, 2015). This Limited Phase II ESA was conducted as a part of the Community-Wide Brownfields Assessment Project for Wheat Ridge to provide information regarding the environmental condition of soil and groundwater at the subject properties. This report presents the findings of the Limited Subsurface Phase II ESA conducted at the subject properties in February 2016, in accordance with the Uniform Federal Policy Quality Assurance Project Plan (UFP-QAPP) prepared for the Phase II work associated with the Wheat Ridge Community-Wide Brownfields Assessments and also the Site-Specific Field Sampling Plan (FSP) (RMC, 2014a and RMC, 2016, respectively). 1.1 Purpose and Scope The Limited Phase II ESA was conducted as part of the Community-Wide Brownfields Assessment Project for the City of Wheat Ridge, Colorado. The City of Wheat Ridge has received funding from the U.S. Environmental Protection Agency (EPA) to assess properties within the City’s identified redevelopment areas that have or are perceived to have environmental concerns related to previous uses or the age of the buildings on site. The City of Wheat Ridge is acting as the lead authority during the completion of the Limited Phase II ESA, with support from EPA Region 8. The objectives of the Limited Phase II ESA were to further assess RECs identified during the Phase I ESA (RMC, 2015) and identify whether potential site contamination caused by current or previous use of the properties exist. Findings of the Limited Phase II ESA were used to assess the extent to which a site presents a threat to human health or the environment by, among other things, collecting and analyzing environmental media samples to determine whether hazardous substances are present at the site and are migrating to the surrounding environment. Additionally, the investigation has assessed the potential threat to human health and safety and the environment (if any) when redeveloping the property and whether the subject property may require a Voluntary Cleanup Plan (VCP). Phase II work was performed in accordance with the guidance outlined in ASTM Standard E1903-11, Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process. Completion of Phase II work was also consistent with the requirements of the Colorado Voluntary Cleanup Program evaluation criteria for soil (e.g., risk-based guidance developed by the State of Colorado or federal government) and water (i.e., Colorado state ground water standards), where applicable. 1.2 Limitations This ESA was performed in accordance with the generally accepted practices of this profession, undertaken in similar studies at the same time and in the same geographical area. RMC has endeavored to meet this standard of care, but may have been limited by conditions encountered during performance of the ESA, a client-driven scope of work, or inability to review information not received by Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 2 the report date. When appropriate, these limitations are discussed in the text of the report and an evaluation of their significance with respect to our findings is also discussed. This Phase II ESA report was prepared for the exclusive use and reliance of the client, City of Wheat Ridge. Use or reliance by any other party is prohibited without the authorization of the City of Wheat Ridge. Reliance on the Phase II ESA by the client and all authorized parties is subject to the terms, conditions, and limitations stated in the Phase II ESA report, and RMC’s agreement for services with the City of Wheat Ridge. The limitation of liability defined in the agreement for services is the aggregate limit of RMC’s liability to the client and all relying parties. RMC does not and cannot represent that the subject property contains no hazardous or toxic materials, products, or other latent conditions beyond that observed by RMC during the Limited Phase II ESA activities. Further, the services herein shall in no way be construed, designed, or intended to be relied upon as legal interpretation or advice. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 3 2 Site Background 2.1 Site Location and Description The subject property consists of approximately 0.64 acres of property on the north side of West 38th Avenue. The 0.64-acre subject property is improved with a single-story house with a finished basement, detached garage, a gardening shed, an outbuilding that was used as an office, and a former chicken coop converted to storage. Access to the house is through a walkway from West 38th Avenue, or through a gated driveway on Eaton Street. Mr. Ron Westover is currently occupying the house. The tenant appear to be in the process of vacating the property. The northern half of the property is enclosed by a wooden fence. A decorative metal fence, on the southern edge of the subject property, extends along West 38th Avenue; this fence is also in front of the neighboring property on West 38th Avenue. A lighted outdoor sign is located in the front yard of the subject property. The lettering on the sign is no longer present. This sign may have advertised the pre-existing dealership (RMC, 2015). The site location is depicted on Figure 1, which was reproduced from a portion of the United States Geological Survey (USGS) 7.5 minute series topographic map. A property use map, included as Figure 2, illustrates residential and commercial businesses located on the adjoining properties. The subject property is bordered by residential properties to the east across Eaton Street, north, and west, and bordered by West 38th Avenue and commercial properties to the south. The observed characteristics of the subject property identified during the Phase I site reconnaissance are provided in the Phase I ESA report (RMC, 2015), as well as further details regarding the adjoining properties. 2.2 Site History The following information is based on a review of historical information obtained for Phase I ESA reports prepared by RMC for the subject property (RMC, 2015). Additional details and documentation can be found in this report. 2.2.1 Subject Property Historical Use Summary The following summary is based on a review of historical information presented in the Phase I ESA report (RMC, 2015). During the Phase I ESA, RMC reviewed reasonably ascertainable historical sources with the objective of identifying obvious uses of the subject property and adjoining sites from the present, back to the subject property’s first developed use, or back to 1940, whichever was earlier. Standard historical sources include: USGS topographic maps; aerial photographs; local street directories; and zoning/land use records. Based on review of available historic information, Assessor records show that the subject property was built in 1933. The historical aerial photograph from 1937 shows multiple buildings on the subject property. Mr. Westover, the current tenant and former owner of the property, stated that he has lived on the property for the past 18 years, and that the property has been strictly residential in that time. He stated that the previous owner operated a wholesale auto resale business and that he repaired and sold automobiles on the property. Many auto parts were observed on the subject property during the site reconnaissance.

Detailed history of these properties is provided in the Phase 1 ESA report (RMC, 2015). Historical aerial photographs show that in 1937 the area to the south of the subject property was primarily agricultural. By 1950, the side streets Fenton, North Depew, and Chase had been constructed, but had not been developed yet. The historical aerial photograph from 1954 shows residential development on Fenton Street and commercial development along West 38th Avenue. More recent historical aerial photographs show the continuing development of commercial properties on West 38th Avenue and the addition of apartment complexes on North Depew Street, south of the subject property. The Cole Criss-Cross Directory from 1968 to 2013 lists many businesses along West 38th Avenue in the proximity of the subject property. On the 1968 Criss-Cross Directory a business named “Dutch HLDY Cleaner” is listed at the 5730 address, which would be directly across West 38th Avenue and hydrogeologically up-gradient to the subject property. RMC was not able to obtain further information regarding the business. The street directories from 1978 up to 2003 also list an auto parts business, first Wheat Ridge Auto Parts, and later, CarQuest, at 5712 West 38th Avenue which is hydrogeologically up-gradient to the subject property. 2.3 Physical Setting RMC has reviewed the current USGS 7.5-minute topographic map and other reasonably ascertainable physical setting sources to obtain information concerning the geologic, hydrogeologic, hydrologic, and topographic characteristics of the site. An excerpt of the topographic map reviewed as a source of the site’s physical setting is included as Figure 1. 2.4 Previous Investigations A Phase I ESA was completed in December 2015 by RMC (RMC, 2015) to identify RECs, as defined in ASTM E 1527-13 and the EPA All Appropriate Inquiries (AAI) rule, associated with the subject property. The Phase I Assessment revealed evidence of RECs in connection with the subject property as described in the following: a historical dry cleaner was present in the 1960s at 5730 West 38th Avenue, and a former auto parts store at 5712 West 38th Avenue, had a documented release, and both are adjoining and hydrologically upgradient of the subject property. The following observations were made in the Phase I ESA: “There is evidence, including auto parts and containers of motor oil and other automotive fluids, that the subject property was used to repair automobiles. Mr. Ron Westover, the tenant and former owner, stated that the previous owner operated a wholesale auto dealership at the property, where he bought wrecked cars, made repairs, and then sold them.” “Ten sites, located within 0.33 miles of the subject property, were evaluated for their potential to present a Vapor Encroachment Condition (VEC), which is the presence or likely presence of chemicals of concern vapors in the sub-surface of the subject property caused by the release of vapors from contaminated soil or groundwater either on or near the subject property. Nine of the sites were ruled out as presenting a VEC based on their locations in regards to topography, estimated groundwater flow direction, and distance from the subject property. One site, the former Wheatridge Auto Parts, located at 5712 West 38th Avenue, could not be ruled out as a source for a VEC.” Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 7 Table 1 Physical Setting Physical Setting of the Subject Property Source Site Address(s) and/or Location 5725 West 38th Avenue, 3825 Eaton Street Wheat Ridge, Jefferson County, Colorado User Provided Parcel Identification Number (s) 39-244-16-025 Jefferson County Assessor’s Records Land Area 28,038 square feet (approx. 0.64 acres) Latitude/Longitude Latitude: 39.769564 , Longitude: -105.059701 (approximate center of the site) Google Maps Topography Location on Public Land Survey System (PLSS) Southwest ¼ Southeast ¼, Section 24, Township 3 South, Range 69 West, 6th Principal Meridian USGS Topographic Map, Arvada, Colorado Quadrangle, 1965, Revised 1994 Elevation Approximately 5,413 feet above mean sea level (MSL) – National Geodetic Vertical Datum (NGVD 1929) Gradient Gently sloping to the north Hydrogeology Estimated Depth to Ground Water Approximately 10 feet below ground surface, based on water levels measured in wells approximately one quarter mile from the subject property.

Soil Type Nunn, clay loam, 0 to 2 percent slopes; 2 to 5 percent slope along northern edge of property USDA Soil Conservation Service, Version 9, Sept. 22 2014 data; accessed 11/13/2015 Description The Nunn soil type is a good farmland soil if irrigated. It is typically well drained with moderate infiltration rates. “The well at the subject property needs to be investigated further to confirm the location and status. The well likely needs to be properly maintained or abandoned. The well is a direct conduit from the ground surface to the water table that presents a potential pathway for any contamination to adversely affect groundwater quality. A licensed well driller should properly abandon this well if it is to remain unused.” Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 8 “There may be environmental issues or conditions at the subject property that parties may wish to access in connection with commercial real estate development that are outside the scope of this Phase I ESA (non-scope considerations). Based on the age of the structures on the 5725 West 38th Avenue property (initially built in 1933), it is likely that some or all structures contain asbestos containing building materials and lead-based paint. An asbestos containing material (ACM) inspection is recommended prior to the renovation, repair, or demolition of site structures should redevelopment of the property take place. If existing structures are demolished, the toxicity characteristic leaching procedure (TCLP) characterization process for lead is also recommended prior to disposal of demolition material. There does not appear to be a potential threat to human health and safety when redeveloping the property as long as handling, removal, and/or disposal of lead-based paint (LBP) materials and ACM (if present) are completed in strict compliance with all current and appropriate federal, state, and local regulations and performed with the proper engineering and regulatory controls by a qualified/licensed professional.” The Phase I ESA (RMC, 2015) included review of environmental database records, which identified 20 regulatory listings within the ASTM-specified approximate minimum search distances. Based on the database review which was conducted with regard to regulatory status, distance, and/or topographic location, the facility listings do not present RECs in connection with the subject property other than the Dutch HLDY Cleaner site mentioned above. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 9 3 Field Activities Field activities conducted for the Limited Subsurface Phase II ESA at the subject property consisted of collection of soil, soil vapor, and groundwater samples for laboratory analyses of potential contaminants of concern. Field activities were completed in accordance with standard operating procedures (SOPs) provided in Appendix A of the project QAPP (RMC, 2014a) and the field sampling methodology discussed in the Site-Specific FSP for the Subsurface Phase II ESA (RMC, 2016). Any variances to the sampling protocol outlined in the QAPP and/or FSP are addressed during the corresponding field activity discussion. 3.1 Direct-Push Boring Advancement and Soil Sampling Soil borings were advanced using a track-mounted GeoProbe® 7730 DT operated by Site Services Drilling, LLC of Golden, Colorado, on February 1, 2016. The direct-push (Geoprobe®) boring locations were selected based on the location of the historical dry cleaner and auto parts store properties and the local hydrological gradient. The boring locations are illustrated in Figure 3. Soil borings were continuously logged by an RMC professional geologist using the Unified Soil Classification System (USCS) for unconsolidated materials. Soil samples were field screened for total volatile organic compounds (VOCs) using a MiniRae 3000 photo ionization detector (PID). There were no indications of potential contamination (e.g., odors or staining) observed or elevated PID readings recorded during drilling and logging activities. Soil borings were advanced to maximum depths of 24 feet (see Table 2 for a list of borehole total depths). At all locations, the presence of tight clayey material or weathered bedrock caused core refusal (i.e., the rig was unable to drive the core to the intended depth). Borehole logs are included in Appendix A. Two soil samples were collected from each borehole and submitted for laboratory analysis. Sample depths ranged from 1 to 12 feet below ground surface (bgs). The borehole locations and soil sample depths are summarized in Table 2. In addition to investigative soil samples, one blind field duplicate and one matrix spike/matrix spike duplicate (MS/MSD) sample pair were collected for quality control purposes. Samples were placed into laboratory provided glass sample jars and labeled with the date, time, unique identifier, and analytical parameters, and placed on ice in a sample cooler. The samples were hand-delivered to Origins Laboratory, Inc. (Origins) in Denver, Colorado, following chain-of-custody protocols, for analysis of VOCs by SW-846 Method 8260C and Lead by SW-846 Method 6010C. The location for boring BH-1 was advanced at a location at the southeast corner of the subject property, closest to the historical dry cleaner. The Geoprobe® core barrel stopped advancing at a depth of 19 feet bgs (core refusal). Soil samples were collected from the material near the surface (0-1’ bgs) because there were no elevated PID readings in this borehole, and one from just above the water table (9-10’ bgs). Boring BH-2 was advanced near the southwest corner of the subject property. The Geoprobe® core barrel stopped advancing at a depth of 19 feet bgs (core refusal). Soil samples were collected from the material near the surface (0-2’ bgs) because there were no elevated PID readings in this borehole, and one from just above the water table (9.5-10.5’ bgs). @A@A @A @A BH-4 BH-3 BH-2 BH-1 G :\w o r k d i r s \W h e a t R i d g e \m x d \W h e a t R i d g e \5 7 2 5 W 3 8 t h P I I F i g u r e 3 .m x d 2 /1 7 /2 0 1 6 3 :2 4 :0 2 P M j k a h l e r t FIGURE 35725 WEST 38TH AVENUECITY OF WHEAT RIDGEBROWNFIELDS ENVIRONMENTAL SERVICES Borehole/Temporary Well Location Map Data Sources: City of Wheat Ridge, RMC Consultants, Inc., Esri, DigitalGlobe,GeoEye, i-cubed, USDA, & USGS.

Soil samples were collected from the material near the surface (0-1’ bgs) because there were no elevated PID readings in this borehole, and one from just above the water table (10-12’ bgs). The blind field duplicate was collected from BH-1 along with sample number BH-1-S-9 and was labeled BH-5-S-9. The extra volume for the MS and MSD was collected from BH-1 along with sample BH-1-S-9. Following borehole advancement, the ground surface at each borehole location was surveyed for elevation for use in groundwater flow direction calculations.

Prior to sampling, soil gases were evacuated from the subsurface of each borehole to ensure that ambient or stagnant air was removed from the sampling system and samples collected were representative of subsurface conditions. Purging equipment consisted of a peristaltic pump. All equipment, including associated valves and fittings, were checked for leaks before purging the sampling system. Purging was performed until two to three purge volumes were evacuated from the drill rods and borehole (determined by the length of the rods at each sampling location). Flow rates for purging (as well as sampling) did not exceed 0.2 Liters per minute (L/min) in accordance with protocol provided in the Petroleum Hydrocarbon Vapor Intrusion Guidance Document (Division of Oil and Public Safety [OPS], 2007). Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 12 One soil gas sample was collected from each of the probe holes at a depth targeting a permeable zone above the water table, at depths of approximately 5 feet bgs. The depth that each sample was collected is provided in Table 3. In addition to investigative soil gas samples, one field duplicate and one ambient blank was collected. Soil‐gas samples were collected in 1-liter canisters supplied and individually certified cleaned and evacuated by Origins of Denver, Colorado, prior to sampling. Since the vacuum inside the canister drives sampling, no additional equipment was necessary, other than a flow controller. The driller provided a screw‐on cap, with a built in sample port, that attaches onto the top of the drill rod to prevent ambient air from diluting the soil gas samples. The sample canisters were fitted with an air‐tight valve and connected to the vapor sampling tubing (1/4 inch diameter), that extends from the probe tip to the sample port located on the drill rod at ground surface, then opened and allowed to fill. Both the initial and final field vacuum readings were recorded prior to and upon the completion of sample collection. The ambient blank and soil gas samples were collected over 30 minutes using flow controllers provided by Origins. The blind field duplicate was collected from BH-3 along with sample BH- 3-VP and labeled BH-5-VP. Samples were hand delivered to the laboratory using chain-of-custody protocol the day after sampling.

As noted above, a track-mounted direct push rig was used to advance the boreholes for the temporary wells. Each well was constructed using one-inch diameter, Schedule 40, slotted (0.010-inch factory slot size) polyvinyl chloride (PVC) well screen and one-inch diameter Schedule 40 PVC blank riser. Monitoring wells were constructed with 10-feet screens, except for BH-4/TMW-4 which was constructed with a 15- foot screen. New PVC screen and riser pipe was installed through the direct push rods at each location. A six-inch bentonite seal was placed at the surface to serve as a temporary surface seal in case the well was not abandoned the same day as installation. Details of the temporary monitoring wells (i.e., location coordinates, total depths, screen intervals) are provided in Table 4. The wells were abandoned per the requirements of the State Engineer’s Office immediately following collection of groundwater samples.

The elevation of the water table at each borehole was calculated using the depth to groundwater and the surveyed elevation of the ground surface; these elevations are given in Table 5. The calculated elevations of the water table would suggest a groundwater flow towards the east. However, the slow water production of BH-1 and observations from the boring logs suggest that the water level at BH-1 had not equilibrated. An inferred elevation based on the depth to groundwater from the soil boring log is also provided, and this water table elevation indicates a groundwater flow direction towards the northeast, which would match the topographical gradient (Figure 3).

The temporary monitoring wells were purged until nearly dry. Two field water quality parameter readings were able to be taken during purging. Because of the lack of readings that were taken for each of these wells, the parameters are assumed to be unrepresentative. Field water quality parameters are provided in Table 6. The wells were purged and sampled using a peristaltic pump. Dedicated tubing was used at each location to prevent cross contamination. The wells were purged and groundwater samples collected on February 3, 2016, two days after the wells were installed. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 14 Groundwater samples were collected in laboratory provided containers and placed on ice in a cooler. Samples were hand-delivered to Origins in Denver, Colorado, for analysis. The groundwater samples were analyzed for VOCs by SW-846 Method 8260C. In addition to investigative groundwater samples, quality control (QC) samples consisting of one field duplicate and one MS/MSD pair were collected and submitted for analysis. The blind field duplicate was collected along with the primary sample TMW-4 and was labeled TMW-5. The extra volumes for MS/MSD analysis were collected from temporary well TMW-3 along with the primary sample TMW-3. Table 6 Field Water Quality Parameters 3.5 Asbestos Containing Materials Sampling See the report provided in Appendix C for a description of the asbestos sampling activities conducted at the subject property. 3.6 Investigative Derived Waste Management Soil cuttings generated during direct push activities (one 5-gallon bucket) were spread around the ground surface in the vicinity of each borehole. The purge water generated during well development and sampling activities (approximately 4 gallons) were discharged to the ground surface in the vicinity of each temporary monitoring well. Miscellaneous disposable PPE, disposable sampling equipment, tubing, acetate liners, and temporary well screens and blank casings used during direct-push and groundwater sample collection activities were collected in plastic bags for disposal as municipal waste at an appropriate landfill. 3.7 Domestic Well Evaluation The domestic well and associated vault and equipment was located at the southern boundary of the subject property, just to the east of the access point in the fence where a piece of electrical conduit was protruding from the ground. RMC personnel removed leaf debris and two rotted pieces of plywood covering the vault. The rotted plywood cover was supported by two 4‐inch by 4‐inch pieces of lumber. The vault was approximately 4‐feet wide by 8‐feet deep. The vault contained a well casing, pressure pump, small hydropneumatic tank, and associated piping and electrical wiring. The well casing did not have a water tight cap and there was no sump pump observed at the bottom of the vault. The well likely contains a submersible pump. The system appeared intact except for the broken electrical conduit protruding from the ground surface. RMC personnel covered the vault with the two rotted pieces of plywood and spread the leaf debris back over the plywood to match the existing surroundings.

Laboratory data reports are included in Appendix B. Details of the assessment of the subject property have not been included or fully developed in this summary, and the report must be read in its entirety for a comprehensive understanding of the items contained herein. 4.1 Soil Sampling The four boreholes advanced during this investigation encountered primarily fine sands and sandy silts. The sandy soils were typically characterized as various shades of yellowish brown, subangular, well sorted, loose, low plasticity, and moist. Tight clayey or silty material or weathered bedrock was encountered at the bottom of each borehole. This hard material caused refusal of the geoprobe core barrel (no further advancement possible). There were no obvious indications of potential contamination such as odor or staining observed. The PID readings were all relatively low with the highest reading of 0.4 ppm being recorded at BH-4 at depths from 7-8 feet bgs. All of the soil samples collected were hand-delivered to the laboratory in one sample delivery group. The soil sample results were all reported by the laboratory in a single report (see Appendix B). 4.1.1 Analytical Results Summary The VOC analyses results for the soil samples collected from the subject property indicate no VOC contamination in any of the samples. The lead analysis results for the soil samples collected from the site ranged from 12.1 milligrams per kilogram (mg/kg) to 96.4 mg/kg, which is far below the 400 mg/kg EPA Regional Screening Level (RSL) for Residential Soils. As described in the Phase 1 ESA for 5725 West 38th Avenue subject property (RMC, 2015), there was a historical dry cleaning facility and an auto parts store with a documented release across the street and hydrologically upgradient from the subject property. Suspected contaminants from a dry cleaning facility would be tetrachloroethene (PCE), trichloroethene (TCE), dichloroethene (DCE), and vinyl chloride (VC). Suspected contaminants from the auto parts store release and the auto repair business on the subject property would be benzene, toluene, ethylbenzene, and xylene. None of these suspected contaminants were detected in the soil samples collected at the subject property. 4.1.2 Data Assessment All surrogate compounds results for the VOC soil sample analyses were within acceptable limits. Matrix Spike/Matrix Spike Duplicate (MS/MSD) recoveries for VOCs were mostly within acceptable limits, except for several compounds, which were recovered above their expected values. MS/MSD relative percent difference (RPD) values were mostly within acceptable limits, except for those same several compounds. These compounds were not detected in any of the primary samples; these out-of-limit results do not affect the project goals or results. The blind duplicate sample (BH-5-S-9) results are the same as for the associated primary sample (BH-1-S- 9). The results are “not detected” for both samples. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 16 4.2 Groundwater Analytical Results All of the groundwater samples collected were hand-delivered to the laboratory in one sample delivery group. The laboratory report for the water sample analyses is included in Appendix B. 4.2.1 Analytical Results Summary The VOC analyses results for the soil samples collected from the subject property indicate no VOC contamination in any of the samples. As described in the Phase 1 ESA for 5725 West 38th Avenue subject property (RMC, 2015), there was a historical dry cleaning facility and an auto parts store with a documented release across the street and hydrologically upgradient from the subject property. Suspected contaminants from a dry cleaning facility would be PCE, TCE, DCE, and VC. Suspected contaminants from the auto parts store release and the auto repair business on the subject property would be benzene, toluene, ethylbenzene, and xylene. None of these suspected contaminants were detected in the groundwater samples collected at the subject property. A summary of groundwater analytical detections is included as Table 7. Laboratory data reports are included in Appendix B.

No Federal MCL available. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 17 4.2.2 Data Assessment All surrogate compounds results for the VOC groundwater sample analyses are within acceptable limits. The blind duplicate sample (TMW-5) results are similar to the associated primary sample (TMW-4). The results are “not detected” for both samples. All the recoveries in the MS results were within acceptable limits, except for chloroethane and methylene chloride. All the recoveries in the MSD sample were within acceptable limits, except for 4- methyl-2-pentanone and methylene chloride. All the RPDs for the MS/MSD pair within acceptable limits, except for the MSD results for 4-methyl-2-pentanone and methylene chloride. Laboratory blank sample results were all “Not detected”. Laboratory control sample (LCS or blank spike) recoveries were all within acceptable limits, except for two compounds which were over estimated. Overall the QC results do not indicate any deficiencies with regard to the sample results, and project goals are achieved. 4.3 Vapor Analytical Results A summary of the findings and analytical results of the soil vapor assessment is provided below. A summary of soil gas analytical detections is included as Table 8. Laboratory data sheets are included in Appendix B. Table 8 summarizes all VOC detections. Compounds that were analyzed for but not detected have been excluded from the summary. Soil gas concentrations were compared to the generic soil gas screening levels provided in Table 2 of the OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (Subsurface Vapor Intrusion Guidance) (EPA, 2002). The target concentrations in Table 2 of this EPA document are screening levels and are not intended to be used as clean-up levels. Soil vapor results indicated low concentrations of 24 VOCs. Only two compounds, 1,3 butadiene and benzyl chloride, exceed the EPA screening levels. 1,3 butadiene was detected at concentrations of 11, 7.63, 6.35, and 6.7 micrograms per cubic meter [µg/m3]) in borings BH-1 through BH-4, respectively. These values exceed the EPA generic deep (5-feet deep or more) soil gas target concentration corresponding to a 10-6 cancer risk level of 0.87 µg/m3. 1,3 butadiene is a compound commonly found in the atmosphere. 1,3 butadiene is released to the air from the burning of organic matter including tobacco or fuels (e.g., wood smoke from stoves or forest fires, vehicle exhaust). Benzyl chloride was detected at concentrations of 10.9, 11.8, and 6.78 µg/m3 in borings BH-2 through BH-4, respectively. These values exceed the EPA generic deep (5-feet deep or more) soil gas target concentration corresponding to a 10-6 cancer risk level of 5 µg/m3. Industrially, benzyl chloride is the precursor to benzyl esters which are used as plasticizers, flavorants, and perfumes. Benzyl chloride may also be used in the synthesis of amphetamine-class drugs, and for this reason, sales of benzyl chloride are monitored as a List II drug precursor chemical by the US Drug Enforcement Administration (DEA). The principal contaminants associated with a dry cleaning facility, PCE, TCE, DCE, and VC, were either not detected or detected at levels well below their EPA screening level thresholds in the soil gas samples collected from the four borehole locations on the subject property (see Table 8). More specifically, these concentrations are below the EPA generic deep soil gas target concentration corresponding to a 10-6 cancer risk level. Although the extent and magnitude of potential contamination in the subsurface beneath the subject property is not definitively known, the potential for residual vapor migration or intrusion into site buildings is considered to be low. The concentrations for all compounds detected from the vapor Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 18 samples are below screening levels, except for the 1,3 butadiene and benzyl chloride. Because there is no known soil or groundwater contamination, the occurrence of 1,3 butadiene is considered anomalous and likely associated with vehicle exhaust or other atmospheric sources. The benzyl chloride concentrations may be from industrial chemical manufacturing of plasticizers, flavorants, and perfumes, and the synthesis of amphetamine-class drugs.

These generic soil-gas screening levels are provided in Table 2 of the OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (EPA, 2002). 4.4 Asbestos Analytical Results See the report provided in Appendix C for the analytical results of the asbestos sampling activities conducted at the subject property. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 20 5 Recommendations The limited subsurface soil and groundwater investigation at the 5725 West 38th Avenue subject property did not identify site contamination that may present a threat to human health or the environment. No contaminants were detected in the soil or groundwater samples. The few contaminants detected in the soil vapor samples were not associated with dry cleaning facilities or automotive repair, and their concentrations were far below their EPA screening values, except for two analytes. The 1,3 butadiene concentrations detected above the screening level appear to be associated with vehicle exhaust or other atmospheric pollutants, and the benzyl chloride concentrations may be from industrial chemical manufacturing of plasticizers, flavorants, and perfumes, and the synthesis of amphetamine-class drugs. However, their presence in the soil gas, at concentrations just above the EPA screening levels, necessitates considerations for the current and future uses of the subject property. Indoor air quality should be tested in any buildings that will remain occupied. For new construction that will be occupied, installation of an active vapor extraction system should be considered. It is recommended that active vapor mitigation measures be included in structure design and construction. Specifically, an active sub-slab depressurization system designed to achieve lower sub-slab air pressure relative to indoor air pressure by use of a fan-powered vent drawing air from beneath the slab. Example guidance documents to assist in the design may include: a. Indoor Air Vapor Intrusion Mitigation Approaches, EPA/600/R-08-115, U.S. Environmental Protection Agency, 49 pp, October 2008. b. Design, Effectiveness, and Reliability of Sub-Slab Depressurization Systems for Mitigation of Chlorinated Solvent Vapor Intrusion, Davild Folkes, presented in a series of EPA seminars on vapor intrusion at the roll-out of the 2002 draft OSWER guidance, 5 pp, 2002 and 2003. c. Designing Commercial Sub-Slab Depressurization Systems, in 2002 International Radon Symposium Proceedings, March 2002, 9 pp. d. ASTM E2435 - 05(2010) e1 Standard Guide for Application of Engineering Controls to Facilitate Use or Redevelopment of Chemical-Affected Properties. Following site development and construction of any structure, conduct periodic vapor monitoring to ensure organic vapors are being effectively removed and mitigated by the active sub-slab depressurization systems. Asbestos removal, in accordance with the Colorado Department of Public Health and Environment’s Regulation No. 8, is required because the amount of asbestos-containing material that is friable or will be made friable during renovation or demolition activities exceeds the trigger levels. Requirements set forth in the Occupational Safety and Health Administration’s Construction Asbestos Standard, 29 CFR 1926.1101 must also be followed when handling asbestos containing material. See Section 8 of the Asbestos Building Survey Report provided in Appendix C for detailed recommendations on handling and disposing of the asbestos identified onsite. Final Limited Phase II ESA Report 5725 West 38th Avenue Wheat Ridge, Colorado 21 The vault containing the domestic well and its appurtenances should, at a minimum, be covered with sturdy materials (i.e., lid and lid supports) to prevent persons from falling through the rotted vault cover. The well should be properly maintained or abandoned according to the rules and regulations of the State Engineer’s Office (see 2 Code of Colorado Regulations [CCR] 402-2). The well is a direct conduit from the ground surface to the water table that presents a potential pathway for any contamination to adversely affect groundwater quality. A licensed well driller should properly abandon this well if it is to remain unused. Findings of the Phase II investigation indicate the presence of hazardous substances (i.e., asbestos and two soil vapor compounds) at the site. Furthermore, there appears to be a low potential threat to human health (e.g., asbestos and soil vapor) and safety (e.g., well vault) when redeveloping the property. However, the risks can be mitigated. Findings from the investigative activities conducted as part of this Limited Phase II ESA do not warrant additional Phase II ESA investigations, nor does this subject property require a voluntary clean-up effort. However, the indoor air quality, asbestos containing materials, and the domestic well vault should be addressed as described above.

The sampling was limited in scope due to the fact that the residence is currently occupied and no destructive sampling or rendering suspect materials friable as a result of sampling occurred. The Environmental Protection Agency (EPA) defines ACM as a material containing greater than one percent (1%) asbestos. Both friable and non-friable materials were sampled. A friable material is a material that when dry may be crumbled, pulverized, or reduced to powder by hand pressure. Because friable materials are more easily damaged and more likely to release fibers into the air, they are of greater concern than non-friable ACM. Random bulk samples were collected of suspect building materials. This asbestos inspection was in general accordance to the guidelines published as the Environmental Protection Agency’s Final Rule: Title II of the Toxic Substances Control Act (TSCA), 15 USC, Sections 2641 through 2654 or in compliance with 40 CFR, Part 763 and the Colorado Department of Public Health and Environment (CDPHE) Regulation #8. Asbestos was found in a number of areas of the building in several types of building materials. Both friable and non-friable ACM was identified. The following sampled materials contain greater than 1% asbestos. • The friable felt backing on Vinyl Sheet Flooring (VSF) materials located in the residence. • The floor tile material located in the basement of the residence. • The paper duct tape materials located on air ducts, and wall heat registers located in the residence. • The joint compound associated with the non-asbestos containing drywall panels located in the northwest bedroom of the residence. • The joint compound associated with the non-asbestos containing drywall panels located in the middle room of the Coop building. 1.1 Introduction At the request of RMC Consultants, Foothills Environmental, Inc. (FEI) conducted a bulk inspection of suspect materials at a single family residence and three out buildings located at 5725 W. 38th Ave. in Wheat Ridge, CO. Lyle Ardourel an Asbestos Inspector certified by the Colorado Department of Public Health & Environment (CDPHE), conducted the asbestos inspection on February 2, 2016. Aerobiology Laboratory Associates Inc., an independent laboratory accredited by the National Voluntary Accreditation Program (NVLAP) and the American Industrial Hygiene Association (AIHA) analyzed the samples utilizing Polarized Light Microscopy (PLM). 1.2 Scope of Work The combined goals of sampling and visual assessments were to: 1. Identify accessible asbestos-containing material (ACM) associated with the building(s) and document the location, condition, friability and quantity of each identified material. 2. Make appropriate recommendations on how to approach each material identified as an ACM prior to demolition or renovation. 3. Coordinate sample data information, observations obtained from the site visits, conclusions and recommendations into a report form. 3 Foothills Environmental, Inc. 11099 W. 8th Avenue, Lakewood, CO 80215 (303) 232-2660 1.3 Standard Bulk Sampling and Analytical Procedures Bulk samples collected were analyzed utilizing the Environmental Protection Agency’s Interim Method for the Detection of Asbestos in Bulk Insulation Samples (EPA 600/M4-82020, December 1982) and the McCrone Research Institute’s The Asbestos Particle Atlas as method reference. For the purpose of this report, any material containing greater than one percent asbestos is considered ACM. 1.4 Building Descriptions This property consists of a single family residence with a basement apartment, detached 2 bay garage, stand-alone office with a 1/2 bath, and a former chicken coop. The original construction date of the residence is 1933. The residence is constructed of wood framing materials with a wood siding and is supported by a poured in place concrete foundation. Mechanical systems consist of a gas furnace and water heater for domestic hot water, both located in the basement. Interior walls and ceilings are primarily constructed of plaster on wood lath and framing. The roof of the residence consists of asphaltic shingles. The detached garage is constructed of concrete block with a brick veneer and is supported by a slab on grade concrete foundation. The detached office building is constructed of wood framing materials with wood siding and are supported by a slab on grade concrete foundations. Interior office walls and ceilings are constructed of drywall on wood framing. The former chicken coop is constructed of wood framing materials with wood siding and is supported by a slab on grade concrete foundation. Interior ceilings are primarily constructed of open wood roof joists and sheathing with some plaster on wood lath and framing and one room finished with drywall and joint compound. The roof of the coop consists of asphaltic shingles. The shed is a pre manufactured wood shed with asphaltic shingles. 1.5 Asbestos Containing Material (ACM) Location Summary The following sections summarize the survey findings and analytical results for suspect ACM sampled at the subject site. ACM summary tables provided below have been prepared for each general sample location: floors, walls, ceilings, etc. These tables are organized to show the material analyzed, its asbestos content, and sample location. Representative samples of suspect materials were sent to an accredited laboratory for analysis. 1.5.1 Statement of Inaccessibility Due to occupancy of the residence, only accessible areas associated of the building were inspected for ACM. FEI did not inspect underground conduit, electrical panels, electrical wire insulation, instruments or other appurtenances. 4 Foothills Environmental, Inc. 11099 W. 8th Avenue, Lakewood, CO 80215 (303) 232-2660 2.0 RESIDENCE ASBESTOS BULK SAMPLE INSPECTION SUMMARY 2.1 Residence Suspect Materials The following suspect materials were identified and sampled on the residence building: • Drywall • Drywall joint compound • Drywall texture (orange peel) • Plaster • Ceiling texture (popcorn) • Acoustical ceiling texture • Vinyl Sheet Flooring (VSF) red stone chip pattern • 4” vinyl cove base (white) and associated mastic (brown) • 4” vinyl cove base (brown) and associated mastic (brown) • Heating system duct tape (grey paper) • 1’ x 1’ floor tile self-stick white marble pattern • 1’ x 1’ floor tile self-stick white blue diamond pattern • 9” x 9” floor tile (pink/painted grey) and associated mastic (black) • Fiber board panel • Window glazing compound • Asphaltic roofing shingle (tan) • Exterior cementitious foundation coating 2.2 Residence Asbestos Containing Materials (ACM) greater than 1% • The approximately 190 square feet of friable felt backing associated with the red stone chip pattern VSF located in the main level kitchen, bathroom and rear entry areas contains 30% chrysotile asbestos. • The joint compound materials associated with the non-asbestos containing drywall panels located on the fasteners, joints and seams in the northwest bedroom walls and ceilings contains 2% chrysotile asbestos. • The approximately 5+ lineal feet and 20 square feet of duct tape (grey paper) material located on assorted heating air ducts located the basement area and inside walls at heat registers contains 80% chrysotile asbestos. • The approximately 20 square feet of pink (painted grey) floor tile located in the basement laundry area contains 8% chrysotile asbestos. • The unknown amount of black tar that was associated with the 4” brown vinyl cove base in the kitchen contains 2% chrysotile asbestos.

Requirements set forth in the Occupational Safety and Health Administration’s Construction Asbestos Standard, 29 CFR 1926.1101 must also be followed when handling asbestos containing material. OSHA-asbestos definition. The one percent cut off is consistent with the definition of an Asbestos containing Material (ACM) under the asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP). However, the OSHA standard has a definition for both "asbestos" and "asbestos-containing materials." The definition of asbestos does not have a one percent cut off, therefore, asbestos that is present in percentages less than one percent continues to be covered by the OSHA standard, 29 CFR 1926.1101. Work operations conducted in areas where the asbestos or asbestos product is below one percent is an "unclassified" operation. The employer still must follow the requirements in paragraphs (g)(1) [except (g)(1)(i)], (g)(2) and (g)(3) that describe engineering and work practice controls operation as well as prohibitions that must be observed regardless of the percentage of asbestos in the installed construction materials. The standard also has exposure-based requirements consisting of a 0.1 fiber/ cc 8 hour Time Weighted Average (TWA) Personal Exposure Limit (PEL) and a 1 fiber/ cc 30-minute excursion limit. Duct tape and duct wrap materials are classified as friable Regulated Asbestos Containing Materials (RACM). The asbestos-containing tape and wrap should not be removed or altered without adhering to all applicable local, state, and federal regulations concerning asbestos removal and disposal. Caution should be exercised when cleaning the surrounding areas or when accessing areas containing duct insulation and wrap. Contact with these materials should be avoided to diminish the potential for damage and the airborne release of asbestos fibers. Periodic condition inspections are recommended until the materials are properly removed. Joint Compounds associated with drywall materials are classified as non-friable Category II ACM as long as the joint compounds remain painted and in good condition. If the joint compounds are damaged by cutting, drilling, sanding etc., or damaged by water or fire, the joint compounds could become friable and release fibers. OSHA has concluded that removal of non-ACM wallboard panels with ACM joint compound poses a potential hazard to workers that must be controlled. If a wall shell is constructed of ACM joint compound and non-ACM wallboard panels, then removal of the wall shell is Class II asbestos work. The following is excerpted from a CDPHE Solid Waste Compliance Bulletin, Asbestos Waste Disposal. Review/revised April 2007. Drywall and drywall mud may contain asbestos. The percent of asbestos contained in drywall and its associated materials, including mud and tape, may be deter-mined based on a representative composite sampling program. Drywall finishing mud and joint compound, referred to simply as "mud", frequently has been found to contain a significant amount of asbestos (i.e. greater than 1%), while the substrate it is applied over may or may not contain any asbestos. The question, then, is how to handle this composite material in the event of a renovation or demolition project that will impact these materials. Two distinct situations may occur: first, the demolition/renovation project may impact the mud alone, such as could be the case during a sanding operation, or second, the demolition/renovation project may impact the composite material (the mud and the substrate drywall it is applied over), such as would be the case in the demolition of the drywall. 12 Foothills Environmental, Inc. 11099 W. 8th Avenue, Lakewood, CO 80215 (303) 232-2660 In the first case, if the mud contains greater than 1% asbestos, the project must be handled as an asbestos abatement project, subject to all the applicable requirements of the Air Pollution Control Division. In the second case, the project is considered to be an asbestos abatement project if the percent of asbestos in the combined mud/drywall composite material is greater than 1%. If, on the other hand, the mud contains 1% or less of asbestos, the material is not considered to be asbestos-containing material for purposes of the Air regulations and is not subject to the asbestos abatement requirements. Similarly, if the composite analysis indicates an asbestos content of 1% or less, even though the mud itself may be greater than 1%, the material is not considered to be asbestos-containing material and does not fall under the asbestos abatement requirements of the Air regulations. In both of these cases, the removed materials may be disposed of as construction and demolition debris – i.e., non-asbestos waste. Adequate documentation must be kept to demonstrate the determination regarding the concentration of asbestos in the materials being disposed. If construction or demolition debris is commingled with any friable asbestos material, it all must be disposed of as asbestos-contaminated debris. Proper materials characterization and planning should occur early in the project to minimize the amount of asbestos-containing waste. Floor tile, and associated mastics is a Category I non-friable ACM. Category I material is defined as asbestos-containing resilient floor covering, asphalt roofing products, packings and gaskets. Asbestos-containing mastic is also considered a Category I material. Category I non-friable ACM that has a high probability of becoming crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations are considered a regulated asbestos-containing material and must comply with CDPHE Regulation No. 8. Vinyl Sheet Flooring is a RACM and has a fibrous backing which is friable. Because of this, vinyl sheet flooring needs to be removed prior to demolition using asbestos trained personnel, wearing proper personal protective equipment prior to demolition. The removal of this material requires adherence to all applicable local, state, and federal regulations concerning asbestos removal and disposal. Window Glazing compounds in good condition are classified as Category II non-friable materials. These materials can become friable if aging and exposure to the weather causes deterioration of the compounds. Abrasive actions such as drilling, hammering, cutting, grinding, etc, will also cause the materials to become friable and should not be performed during maintenance activities without following proper precautions. Any removal of or alteration to asbestos- containing window glazing compounds requires adherence to all applicable local, state, and federal regulations concerning removal and disposal of asbestos materials. 8.1 Building demolition requirements The following work practice should be followed whenever demolition/renovation activities involving RACM occur: Notify EPA of intention to demolish/renovate, remove all RACM from a facility being demolished or renovated before any disruptive activity begins or before access to the material is precluded, keep RACM adequately wet before, during, and after removal operations, conduct demolition/renovation activities in a manner which produces no visible emissions to the outside air, and handle and dispose of all RACM in an approved manner. The NESHAP requires that all friable asbestos containing material must be removed prior to a demolition. Category I non-friable ACM that is not in poor condition and is not friable nor will become crumbled, pulverized, or reduced to powder during demolition activities may remain in place. Standard demolition procedures (ie: wrecking ball and crane, bulldozer wrecking, heavy equipment loading or material handling...) may cause Category II ACM to become crumbled, pulverized, or reduced to powder. If so, the techniques may not be used or the material should be removed prior to demolition. 13 Foothills Environmental, Inc. 11099 W. 8th Avenue, Lakewood, CO 80215 (303) 232-2660 8.2 Post building demolition requirements If a building is demolished with non-friable asbestos containing materials in place then any asbestos containing material remaining in the post demolition soil would be subject to the Colorado Hazardous Waste or Solid Regulations, in which the area of asbestos-contaminated soil may be considered a Solid Waste Management Unit (SWMU), an area of concern (AOC). In accordance with Section 5.5.2 of the Solid Waste Regulations, the following projects are exempt from the requirements of Section 5.5 of the Solid Waste Regulations, but may be subject to other sections of the Solid Waste Regulations or other regulatory programs: • Non-friable Material Removed From Soil - In situations where the soil contains solely non-friable material containing asbestos that has not been rendered friable, the non-friable material can be removed from the soil and properly disposed of in accordance with Section 5.2 of the Solid Waste Regulations. The surrounding soil would not be considered to be asbestos-contaminated soil and therefore would not be subject to the requirements of Section 5.5 of the Solid Waste Regulations. The determination that a material is non-friable must be made by an asbestos Building Inspector who has been certified in accordance with Air Regulation No. 8, Part B and who has a minimum of six (6) months experience in asbestos-contaminated soil inspections. 9.0 LIMITATIONS This report describes the locations and conditions of ACM identified in the facility during the inspection.

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.
