PROJECT OVERVIEW
1.0 Introduction
On April 8, 2013, Ms. Blake Bradley with DS Consulting, Inc. (DSC) conducted a limited asbestos
inspection and collected asbestos bulk-samples of suspect asbestos-containing materials (ACM) within a
portion of the single-family residence located at 1462 Green Hill Ct. Vail, Colorado.
The purpose of the limited inspection was to identify and sample potentially hazardous friable and non-
friable ACM that may be impacted by subsequent restoration/renovation activities.
2.0 Scope of Work
The scope of the limited inspection and bulk-sampling was limited to specific areas and materials of the
residence defined by the restoration company. These included the textured drywall in the main level
bedroom and hallway, as well as the upper level bedroom. The remaining areas and materials within the
residence, garage or any out-building 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
The residence is a multi-level, single-family residence with a finished basement and a two-car attached
garage.
4.0 Certifications
The limited asbestos inspection and bulk-sampling was conducted by Ms. Blake Bradley with DSC. DSC is
a Colorado Department of Public Health and Environment (CDPHE) certified Asbestos Consulting Firm,
Registration No. 14912. Ms. Bradley is a CDPHE certified Building Inspector; having certification number
16862 (seeAppendixAforcertificates).
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).
DSC 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
3
conducted; however, walls, columns and perimeter pipe chases were not broken into in order to locate
and quantify suspect ACM. It should be noted that additional ACM might be located in these and other
inaccessible areas.
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).
The percentage of asbestos within each individual bulk-sample can vary depending on sample location,
homogeneity of the material, and the type of application. Any sample reporting a "TRACE" amount of
asbestos must be considered positive for asbestos greater than 1% unless it is re-analyzed utilizing the
point-count method and verified to be less than 1%.
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. DSC 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.
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
4
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
DSC 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 ftz of material requires a minimum of three (3) samples; between
1,000 ftz and 5,000 ftz 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
7.0 Overview of Findings
Asbestos was not reported within the drywall texture collected and analyzed. DSC collected a total
of three (3) asbestos bulk-samples of one (1) homogeneous area.
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.

8.0 Conclusion & Recommendations
Asbestos was not identified within the materials of the residence that were within the scope of the
limited inspection and bulk-sampling performed on January 14, 2013; therefore, no professional
abatement activities are required to remove or disturb the above-referenced sampled materials.
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 ftz 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 ftz 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. DSC can provide the client or building owner with a proposal
for project design, abatement oversight and air monitoring upon request.
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. crushing mastic-coated
concrete), these materials must be abated of all ACM prior to shipping offsite for recycling.
OSHA regulations regarding occupational exposure during demolition activities is 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 are 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.
10.0 Major & Minor Asbestos Spill Response Actions
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. (1Votifications) 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.
In the event of an asbestos spill involving less than or equal to the trigger levels, the building owner or
contractor should take the following non-mandatory steps:
• Restrict entry 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 fibers to
other areas in the building.
• Seal all openings between the contaminated and uncontaminated areas. This is to be accomplished
by using polyethylene sheeting to cover all areas such as windows, doorways, elevator openings,
corridor entrances, drains, grills, grates, diffusers and skylights.
• HEPA vacuum or steam clean all carpets, draperies, upholstery and other non-clothing fabrics in
the contaminated area, or discard all contaminated materials in accordance with subsection III.R.
(Waste Handling).
• Launder or discard contaminated clothing in accordance with subsection III.R. (Waste Handling).
• HEPA vacuum or wet clean all non-fabric surfaces in the contaminated area.
• Following completion of subparagraphs III.T.2.a. through III.T.2.f. of Regulation 8, conduct air
monitoring as described in paragraph III.P.3 of Regulation 8. (Final Clearance Air Monitoring and
Sample Analyses); 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 work area.
