PROJECT OVERVIEW
__________________________________________________________________________________________________________________
1.0 Introduction
On June 29th 2021,Gary Farrell with SilverKey Services conducted a limited asbestos inspection
and collected asbestos bulk-samples of suspect asbestos-containing materials (ACM) within a
portion of the master bedroom, bathroom, kitchen,living room, upstairs bedroom, and closet
located at 249 Mountain View Ln. Estes Park, CO 80517
The purpose of the limited inspection was to identify and sample potentially hazardous friable and
non-friable ACM that has either been affected by a recent water loss and/or may be impacted by
subsequent restoration activities.
2.0 Scope of Work
The scope of the limited inspection and bulk-sampling was limited to specific areas of the residence
defined by the contractor. The following areas include:the master bedroom ceiling surfacing
material, bathroom ceiling surfacing material, living room ceiling surfacing material, upstairs
bedroom wall surfacing material, kitchen wall joint compound/drywall, closet wall joint
compound/drywall, bathroom wallpaper, as well as bathroom shower tile and adhesive. The
remaining areas within the residence, garage or any outbuilding on the property were not included
in the scope of the inspection. The limited asbestos inspection did not constitute a full building
inspection and does not fulfill the asbestos inspection requirements for structures that are to be
demolished
3.0 Site Description
Single Family Residence
4.0 Certifications
The limited asbestos inspection and bulk-sampling was conducted by Gary Farrell with SilverKey
Services. Gary Farrell is a Colorado Department of Public Health and Environment (CDPHE)
certified Building Inspector; having certification number 25590.
5.0 Inspection, Sampling & Analytical Procedures
5.1 Inspection Procedures
The limited asbestos inspection was conducted by an Environmental Protection Agency (EPA) and
CDPHE certified Building Inspector. The inspection procedures included identifying and sampling
suspect ACM within the pre-defined areas, submitting samples to an accredited laboratory for
analysis, classifying the materials and assessing their condition, and compiling a final report
detailing the inspection and the analytical results of the bulk-samples.

5.2 Sampling Procedures
Statistically random bulk-samples representative of the suspect ACM of each homogeneous area
were collected according to the guidelines published as EPA Final Rule: Title II of the Toxic
Substances Control Act (TSCA), 15 USC, Sections 2641 through 2654 and in compliance with 40
CFR, Part 763 and CDPHE Regulation Number 8, Part B- Asbestos (Reg. 8).
SilverKey Services has collected the appropriate number of bulk-samples to meet all regulatory
requirements for the classification and quantity of each homogeneous area. Some minor destructive
sampling was conducted; however, walls, columns and perimeter pipe chases were not broken into
in order to locate and quantify suspect ACM. SilverKey Services is not responsible for repairing the
damage from collecting bulk samples. It should be noted that additional ACM might be located in
these and other inaccessible areas.
Materials containing less than 1% asbestos are not regulated by CDPHE Regulation 8, Part B –
Asbestos. However, all demolition/abatement activities should be performed following the
applicable Occupational Safety and Health Administration (OSHA) regulations. This would include,
but not limited to, the appropriate asbestos training for the type of material being
removed/disturbed as well as having a properly trained supervisor onsite, using wet removal
methods, wearing adequate personal protective equipment (HEPA-filtered particulate respirators),
medical surveillance of workers, personal-exposure air monitoring, area air monitoring in occupied
buildings, etc. There may also be landfill disposal requirements for these materials, depending on
the facility. SilverKey Services recommends that all demolition/renovation areas involving any
amount of asbestos be subjected to visual inspections and a final clearance air testing by a
CDPHE-certified Air Monitoring Specialist (AMS) after the work has been completed, but before any
containments are dismantled and the area is reoccupied.
5.3 Analytical Procedures
All asbestos bulk-samples were analyzed by a National Voluntary Laboratory Accreditation
Program (NVLAP) accredited laboratory via Polarized Light Microscopy (PLM) for asbestos content
(see Appendix B for laboratory report).
6.0 Homogeneous Areas
A Homogeneous Area (HA)includes materials that are uniform in appearance, color, texture and date
of application. The asbestos content of the bulk-samples collected within a homogeneous area can
be applied to the entire homogenous area if they conform to the above characteristics and the
regulated minimum sample quantities of each type of material are collected and analyzed.
6.1 Material Friability
A material can either be friable or non-friable.A friable material is one that, when dry, can be
pulverized, or reduced to powder by hand pressure,a non-friable material cannot. A non-friable
material may become friable if its condition had deteriorated or has been impacted by forces that
have rendered it friable.

6.2 Material Classifications
Sampled materials are divided into one of the following three categories:
•Surfacing Material: sprayed or troweled onto structural building members
•Thermal System Insulation (TSI): any type of pipe,boiler, tank, or duct insulation
•Miscellaneous Material: all other materials not classified in the above two categories
6.3 Material Conditions
Sampled materials are placed into one of the three following categories of conditions:
•Good: none to very little visible damage or deterioration
•Damaged: the surface is crumbling, blistered, water-stained,gouged, marred or otherwise abraded
over less than one-tenth of the surface if the damage is evenly distributed, or one-quarter if the
damage is localized
•Significantly Damaged: the surface is crumbling,blistered, water-stained, gouged, marred or
otherwise abraded over greater than one-tenth of the surface if the damage is evenly distributed, or
one-quarter if the damage is localized
6.4 Sample Quantities
SilverKey Services collected at least the minimum number of samples from each homogeneous area
necessary to meet all regulatory requirements for the quantity of material to be disturbed. The
quantities listed in this report are approximate and on-site verification of the exact quantity of each
material is required. The following outlines the minimum sample quantities required per
homogeneous area:
•Surfacing Materials: up to 1,000 ft2 of material requires a minimum of three (3) samples; between
1,000 ft2 and 5,000 ft2 of material requires a minimum of five (5) samples; over
5,000 ft2 of material requires a minimum of seven (7) samples; one (1) sample of each patch
•Thermal System Insulation (TSI): each homogeneous area requires a minimum of three (3)
samples; at least one (1) sample must be collected from each patch; and collect enough samples
sufficient to adequately assess the material and determine the asbestos content for TSI fittings such
as pipe elbows or T’s.
•Miscellaneous Materials: collect enough samples sufficient to determine the asbestos Content
7. Overview of Finding
Asbestos was reported within some of one or more of the samples collected. Therefore, abatement
of these materials will be required. SilverKey Services collected a total of (13) asbestos bulk-samples
of (5) homogeneous areas.
Table 1 below describes the materials composing each homogeneous area as well as the locations of
each bulk-sample collected. Also listed is the classification,condition, friability and estimated
quantity of material to be removed and/or disturbed,as well as the asbestos content within each
bulk-sample. Please see Appendix B: Analytical Data for the layer break-down of each bulk-sample.

8. Findings & Recommendations
ACM was identified within the following areas: the master bedroom ceiling surfacing material, bathroom
ceiling surfacing material, kitchen ceiling surfacing material, living room ceiling surfacing material,
upstairs bedroom wall surfacing material, kitchen wall joint compound, closet wall joint compound, as
well as the bathroom wallpaper in mud that were within the scope of the limited inspection and
bulk-sampling performed on June 29th 2021.; therefore,professional abatement activities are required to
remove or disturb the above-reference sampled materials.ACM was not impacted or disturbed. We do not
consider this a spill; SilverKey Services recommends that when ACM is removed/abated, that only a
licensed asbestos abatement contractor using personnel trained in the handling of ACM be allowed to
conduct such activities using appropriate methods (HEPA- filtered vacuuming, wet cleaning methods,
respiratory protection, protective clothing, personnel decontamination, negative-air enclosures, air
monitoring, etc.).
For all spills, SilverKey Services recommends that all soft goods (carpet, pad, clothes, couches, etc.)and
any ceiling and/or wall surfacing restoration activities be removed from the interior of the building as
asbestos waste. SilverKey Services also advises that only hard surfaces (plastic, metal, wood, concrete,
etc.) are allowed to be left in place before the final visual and final air clearance tests are completed.
SilverKey Services urges that electronics and appliances (refrigerators, air conditioners, DVD players,
microwaves, toasters, etc.) are removed due to the mechanical openings and working parts that make it
difficult to clean thoroughly.
8.1. ASBESTOS SPILL RESPONSES
Major Spill Response Protocols
If ACM is significantly damaged and the total quantity exceeds the regulatory trigger levels, the area is
deemed a “Major Asbestos Spill.” The area is consequently subject to the requirements in Reg. 8, Section
III.T.1. – Major Asbestos Spills, as outlined below.
Additional asbestos air or dust sampling should also be conducted within the remaining areas not directly
impacted by the Major Asbestos Spill to determine if asbestos-containing dust/debris has spread to
adjacent areas. If asbestos fibers are found within any other areas or on building contents, they should be
included in the scope of professional abatement and decontamination.
The following response actions must be followed per Colorado Reg. 8 when a Major Asbestos Spill
occurs:
•Restrict access to the area and post warning signs to prevent entry to the area by persons other than
those necessary to respond to the incident.
•Shut off or temporarily modify the air handling system to prevent the distribution of asbestos fibers to
other areas.
• Immediately contact the Division by telephone, submit a notification in compliance with subsection
III.E. (Notifications) and, if in an area of public access, apply for a permit in accordance with
subsection III.G. (Permits).
•Be exempted from the requirements to have a certified Supervisor on-site at all times, until such time as
the immediate danger has passed. Any cleanup or asbestos abatement that must occur after the
immediate danger has passed shall be supervised by a person certified by the Division.

• Using certified Supervisors and certified Workers in accordance with section II. (Certification
Requirements) of this Regulation, seal all openings between the contaminated and uncontaminated
areas and establish none- detect air pressure within the contaminated area in accordance with paragraph
III.J. (Air Cleaning and None- detect Pressure Requirements).This is to be accomplished using
polyethylene sheeting to cover areas such as doorways,windows, elevator openings, corridor entrances,
grills, drains, grates, diffusers and skylights.
•HEPA vacuum or steam clean all carpets, drapes, upholstery,and other non-clothing fabrics in the
contaminated area, or discard these materials.
• Launder or discard contaminated clothing in accordance with subsection III.R. (Waste Handling).
• HEPA vacuum or wet clean all surfaces in the contaminated area.
•Discard all materials in accordance with subsection III.R. (Waste Handling).
•Following completion of subparagraph III.T.1.a. through III.T.1.i. above, comply with air monitoring
requirements as described in subsection III.P. (Clearing Abatement Projects); air samples shall be
collected aggressively as described in 40 C.F.R. Part 763, Appendix A to Subpart E (EPA 1995), except
that the air stream of the leaf blower shall not be directed at any friable ACM that remains in the area
and comply with any other measures deemed necessary by the Division to protect public health.
Minor Spill Response
If ACM is significantly damaged and the total quantity is less than the regulatory trigger levels, however,
more than three square feet or three linear feet (3 ft2/3 ln/ft.), the area is deemed a “Minor Asbestos
Spill.” The area is consequently subject to the requirements in Reg. 8, Section III.T.2. – Minor Asbestos
Spills, as outlined below.
Additional asbestos air or dust sampling should also be conducted within the remaining areas not directly
impacted by the Minor Asbestos Spill to determine if asbestos-containing dust/debris has spread to
adjacent areas. If asbestos fibers are found within any other areas or on building contents, they should be
included in the scope of professional abatement and decontamination.
The following response actions must be followed per Colorado Reg. 8 when a Minor Asbestos Spill
occurs:
• Restrict access to the area and post warning signs to prevent entry to the area by persons other than
those necessary to respond to the incident.
• Shutoffortemporarilymodifytheairhandlingsystemtopreventthedistributionofasbestosfiberstoother

areas and establish none-detect air pressure within the contaminated area in accordance with paragraph
III.J. (Air Cleaning and None-detect Pressure Requirements).This is to be accomplished using
polyethylene sheeting to cover areas such as doorways,windows, elevator openings, corridor entrances,
grills, drains, grates, diffusers and skylights.

contaminated area, or discard these materials.
•Launder or discard contaminated clothing in accordance with subsection III.R. (Waste Handling).
•HEPA vacuum or wet clean all surfaces in the contaminated area.
•Discard all materials in accordance with subsection III.R. (Waste Handling).
•Following completion of subparagraph III.T.1.a. through III.T.1.i. above, comply with air monitoring

that the air stream of the leaf blower shall not be directed at any friable ACM that remains in the area
and comply with any other measures deemed necessary by the Division to protect public health.
9.0 Asbestos Abatement & Demolition Requirements
If ACM is to be removed or disturbed in a single-family residence, and the total quantity exceeds any
of the regulatory trigger levels of 50 linear ft.on pipes, 32 ft2 on other surfaces, or the volume
equivalent of a 55-gallon drum, a CDPHE-certified General Abatement Contractor (GAC) is required
to perform the work. The regulatory trigger levels within a commercial building are 260 linear ft. on
pipes, 160 ft2 on other surfaces, or the volume equivalent of a 55-gallon drum. In addition, formal
notification to CDPHE prior to the abatement of ACM as well as air monitoring, visual inspections,
and final air clearances by a CDPHE-certified Asbestos AMS is required.
CDPHE regulations allow for the demolition of a building that contains non-friable asbestos
containing materials, such as caulking, mastic or resilient floor tiles. However, demolition must be
completed without causing the non-friable ACM to be rendered friable. Burning a building with any
ACM is prohibited. Operations such as sanding, cutting,crushing, grinding, pneumatic jacking, etc. of
ACM are not permitted. Recycling of building materials such as concrete, metal, or wood that are
bonded or contaminated with ACM, e.g. glue, caulking,or mastic is also prohibited. If any of the
non-friable asbestos containing materials are to be recycled and rendered friable after demolition
(i.e.7 crushing mastic-coated concrete), these materials must be abated of all ACM prior to shipping
off site for recycling. OSHA regulations regarding occupational exposure during demolition activities
are still mandatory. OSHA 29 CFR 1926.1101 requires that workers performing
construction-related activities be protected from asbestos fibers in excess of the permissible
exposure limit of 0.1 f/cc of air. Contractors must comply with applicable provisions of OSHA 29
CFR 1926.1101 during demolition and renovation activities.These OSHA provisions include, but are
not limited to, PPE and respirators, personnel training,personal-exposure air monitoring, employee
medical surveillance, wet removal methods, signage for regulated areas, etc.
