Executive Summary
RMC Consultants, Inc. (RMC) has prepared this Phase II Environmental Site Assessment (ESA) for the
residential property located at 11818 West 52nd Avenue in Wheat Ridge, Jefferson County, Colorado,
hereafter referred to as the “subject property” in accordance with the Phase II Environmental Site
Assessment Field Sampling Plan for 11818 West 52nd Avenue Wheat Ridge, Colorado, dated December 8,
2015. A Phase II ESA was recommended for the subject property based on the age of the site
improvements and at the request of the City of Wheat Ridge. The property asbestos containing material
survey was conducted by Mr. Lyle Ardourel of Foothills Environmental, Inc. on November 10, 2015 and
again on December 3, 2015.
A summary of the findings of the Phase II ESA is provided below. Details of the assessment of the
subject property have not been included or fully developed in this summary, and the attached 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.
This property consists of a single family residence with a detached garage, four detached wood framed
out buildings (West Out Buildings), and a pre‐fabricated metal alpaca barn). The date of original
construction is 1935. The original residence is constructed of wood framing materials with a brick
veneer and is supported by a poured in place concrete foundation. Mechanical systems consist of a gas
furnace (converted from coal) 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 cementitious shingles. The detached garage is constructed of wood framing
materials with a brick veneer and is supported by a slab on grade concrete foundation. The detached
out buildings are constructed of wood framing materials with wood siding and are supported by a slab
on grade concrete foundations.
The 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 of the buildings were inspected for ACM. Inspection
of underground conduit, electrical panels, electrical wire insulation, instruments or other appurtenances
were not performed. The interior of the metal alpaca barn building was occupied by alpacas and thus
was not accessed for this November 10, 2015 assessment. The attic of the residence was inaccessible
and not included in this November 10, 2015 assessment. However, attic insulation samples were
collected on December 3, 2015. The attic insulation samples were non‐detect for asbestos.
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. 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.

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 non‐friable roofing tar used to patch and seal small areas of roofs.
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 wrap and paper duct tape materials located on air ducts, furnace exhaust and
wall heat registers located in the residence.
The boiler refractory material located on the furnace of the residence.
The non‐friable cementitious roofing shingles located on the roof of the residence.
The window glazing compound material located on the west out building shop.
The silver paint associated with tar paper vapor barrier located on the west out building wood
shed.
For the purpose of this report, any material containing greater than one percent asbestos is considered
ACM. Recommended actions are provided in the attached report and it should be read in it’s entirety.
To summarize, recommendations include:
Removal, in accordance with the Colorado Department of Public Health and Environment’s
Regulation No. 8, is required if the amount of asbestos‐containing material that is friable or will
be made friable during renovation or demolition activities.
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 attached report).
Asphaltic roofing materials in good condition are classified as non‐friable Category I asbestos
containing material. Asphaltic roofing materials are generally pliable and are a potential health
concern if they become dry and brittle from age and continued exposure to sun, heat and air.
Abrasive actions such as sanding, grinding, drilling, sawing, etc. should not be performed on this
material.
In accordance with Colorado Regulation No. 8, Section III.S.3. Asphaltic Materials ‐ Tar
impregnated roofing felts, asphalt roofing tiles, roofing asphalts, roofing mastics, and asphaltic
pipeline coatings that are non‐friable and will remain non‐friable during abatement are exempt
from this regulation. At the time of inspection, none of the asbestos containing roofing
materials were observed to be in a friable condition.
Duct tape and wrap are classified as friable materials. 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.
Boiler refractory materials are classified as non‐friable as long as the materials remain
undamaged and in good condition. If the materials are damaged by cutting, drilling, sanding

3
etc., the materials could become friable and release fibers. Any removal of or alteration to
asbestos‐containing refractory materials requires adherence to all applicable local, state, and
federal regulations concerning removal and disposal of asbestos materials. Caution should be
exercised when accessing areas containing boiler refractory materials. Contact with these
materials should be avoided to diminish the potential for damage and airborne release of
asbestos fibers.
Vinyl sheet flooring has a fibrous backing which is friable. Vinyl sheet flooring needs to be
removed 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 (see attached report).
Window Glazing compounds are classified as non‐friable materials. These materials can become
friable if aging and exposure to the weather causes deterioration of the compounds (see
attached report). 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.
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:
o 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.
RMC initiated this Phase II ESA for the residential property located at 11818 West 52nd Avenue in Wheat
Ridge, Jefferson County, Colorado, (subject property) in accordance with the Phase II Environmental Site
Assessment Field Sampling Plan November 5, 2015. Any exceptions to, or deletions from, this practice
are described in Attachment 1 of this report. It is recommended that the attached report be read in its

1.0 EXECUTIVE SUMMARY
This limited bulk sampling of suspect building materials was conducted to identify Asbestos Containing
Material (ACM) in the building before a proposed building demolition. 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 non-friable roofing tar used to patch and seal small areas of roofs.
• 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 wrap and paper duct tape materials located on air ducts, furnace exhaust and wall
heat registers located in the residence.
• The boiler refractory material located on the furnace of the residence.
• The non-friable cementitious roofing shingles located on the roof of the residence.
• The window glazing compound material located on the west out building shop.
• The silver paint associated with tar paper vapor barrier located on the west out building wood shed.
1.1 Introduction
At the request of RMC Consultants, Foothills Environmental, Inc. (FEI) conducted a limited bulk inspection of suspect materials at a single family residence and three out buildings located at 11818 W. 52nd Ave. in
Wheat Ridge, CO. Lyle Ardourel an Asbestos Inspector certified by the Colorado Department of Public
Health & Environment (CDPHE), conducted the limited asbestos inspection on November 10, 2015. 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.

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 detached garage, four detached wood framed out
buildings (West Out Buildings), and a pre-fabricated metal alpaca barn. The original date of original
construction is 1935. The original residence is constructed of wood framing materials with a brick veneer and is supported by a poured in place concrete foundation. Mechanical systems consist of a gas furnace
(converted from coal) 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 cementitious shingles. The detached garage is constructed of wood framing materials with a
brick veneer and is supported by a slab on grade concrete foundation. The detached out buildings are constructed of wood framing materials with wood siding and are supported by a slab on grade concrete
foundations.
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. FEI did no destructive sampling or sampling of materials that would render suspect materials friable as a result of sample collection because of occupancy of the main structure. The interior
of the metal alpaca barn building was occupied by alpacas and thus was not accessed for this November 10, 2015 assessment. Any suspect materials located in these areas should be assumed asbestos containing until sample collection and subsequent analysis prove otherwise.

4.0 ALPACA BARN ASBESTOS BULK SAMPLE INSPECTION SUMMARY
4.1 Accessible Alpaca Barn Suspect Materials
• No suspect materials were identified on the north exterior components of the prefabricated
metal Alpaca Barn:
4.2 Inaccessible Alpaca Barn Materials (presumed greater than 1%)
• Due to the presence of alpacas FEI did not access the most of the exterior as well as the interior
areas of the Alpaca Barn at the time of the November 10, 2015 assessment.
5.0 ASBESTOS RECOMMENDED ACTIONS
Removal, in accordance with the Colorado Department of Public Health and Environment’s Regulation No.
8, is required if the amount of asbestos-containing material that is friable or will be made friable during
renovation or demolition activities exceeds the trigger levels of 260 linear feet on piping or 160 square feet on other surfaces or the volume equivalent of a 55-gallon drum for all areas other than single-family
residential dwellings. 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.
Asphaltic roofing materials in good condition are classified as non-friable Category I asbestos containing
material. Asphaltic roofing materials are generally pliable and are a potential health concern if they become
dry and brittle from age and continued exposure to sun, heat and air. Abrasive actions such as sanding, grinding, drilling, sawing, etc. should not be performed on this material.
In accordance with Colorado Regulation No. 8, Section III.S.3. Asphaltic Materials - Tar impregnated
roofing felts, asphalt roofing tiles, roofing asphalts, roofing mastics, and asphaltic pipeline coatings that are non-friable and will remain non-friable during abatement are exempt from this regulation. At the time of
this inspection, none of the asbestos containing roofing materials were observed to be in a friable condition.
Boiler refractory materials are classified as non-friable as long as the materials remain undamaged and
in good condition. If the materials are damaged by cutting, drilling, sanding etc., the materials could become friable and release fibers. Any removal of or alteration to asbestos-containing refractory materials
requires adherence to all applicable local, state, and federal regulations concerning removal and disposal of
asbestos materials. Caution should be exercised when accessing areas containing boiler refractory materials. Contact with these materials should be avoided to diminish the potential for damage and airborne
release of asbestos fibers.

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.
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.
Vinyl Sheet Flooring 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.
Vermiculite Wall and Ceiling Insulation (may be present in the residence) is classified as a friable
material. The wall insulation was meant to be inside of the walls. When it has breached the wall
containment and exists outside the wall, it should be considered damaged. As long as the insulation is contained within its installed locations, its condition is considered in good condition. Penetration of wall
and ceiling systems that contain vermiculite insulation should adhere to all required local, state, and federal regulation concerning asbestos removal and disposal as well as applicable O&M procedures specific to the facility. Periodic condition inspections are recommended until the material is removed.
Window Glazing compounds in good condition are classified as 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.
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.

All regulated asbestos minerals (i.e. chrysotile, amosite, crocidolite, anthophyllite, tremolite, and actinolite) were sought in every layer of each sample, but only those asbestos
minerals detected are listed. Amosite is the common name for the asbestiform variety of the minerals cummingtonite and grunerite. Crocidolite is the common name used for the
asbestiform variety of the mineral riebeckite.
Tile, vinyl, foam, plastic, and fine powder samples may contain asbestos fibers of such small diameter (< 0.25 microns in diameter) that these fibers cannot be detected by PLM.
For such samples, more sensitive analytical methods (e.g. TEM, SEM, and XRD) are recommended if greater certainty about asbestos content is required. Semi-quantitative bulk TEM
floor tile analysis is accepted under NESHAP regulations.
These results are submitted pursuant to Aerobiology Laboratory Associates, Inc.’s current terms and conditions of sale, including the company’s standard warranty and limitation
of liability provisions. No responsibility or liability is assumed for the manner in which the results are used or interpreted.
Unless notified in writing to return the samples covered by this report, Aerobiology Laboratory Associates, Inc. will store the samples for a minimum period of thirty (30) days
before discarding. A shipping and handling charge will be assessed for the return of any samples.
Aerobiology does not guarantee the results of tape lifts, microvacs, wipe, and/or debris samples. Accurate analysis cannot be performed due to particle size, media used, and/or
amount of material given. Analysis of these materials should be preformed by a TEM. A result of ND does not indicate that the sample area does not contain asbestos. It means the
analyst could not identify asbestos in the specific sample for the reasons listed above.

This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the Federal Government.
All regulated asbestos minerals (i.e. chrysotile, amosite, crocidolite, anthophyllite, tremolite, and actinolite) were sought in every layer of each sample, but only those asbestos
minerals detected are listed. Amosite is the common name for the asbestiform variety of the minerals cummingtonite and grunerite. Crocidolite is the common name used for the
asbestiform variety of the mineral riebeckite.
Tile, vinyl, foam, plastic, and fine powder samples may contain asbestos fibers of such small diameter (< 0.25 microns in diameter) that these fibers cannot be detected by PLM.
For such samples, more sensitive analytical methods (e.g. TEM, SEM, and XRD) are recommended if greater certainty about asbestos content is required. Semi-quantitative bulk TEM
floor tile analysis is accepted under NESHAP regulations.
These results are submitted pursuant to Aerobiology Laboratory Associates, Inc.’s current terms and conditions of sale, including the company’s standard warranty and limitation
of liability provisions. No responsibility or liability is assumed for the manner in which the results are used or interpreted.
Unless notified in writing to return the samples covered by this report, Aerobiology Laboratory Associates, Inc. will store the samples for a minimum period of thirty (30) days
before discarding. A shipping and handling charge will be assessed for the return of any samples.
Aerobiology does not guarantee the results of tape lifts, microvacs, wipe, and/or debris samples. Accurate analysis cannot be performed due to particle size, media used, and/or
amount of material given. Analysis of these materials should be preformed by a TEM. A result of ND does not indicate that the sample area does not contain asbestos. It means the
analyst could not identify asbestos in the specific sample for the reasons listed above.
