Purpose of Sampling
On Mesa Environmental preformed a limited inspection and asbestos testing of areas damaged
by to the property located at Deer Park Road, De Beque, CO 81630. Only those materials as
indicated by the client and the client’s representatives as being impacted were
sampled/analyzed. Demolition requires removal of materials in the bedroom, kitchen, and roof
causing damage to the drywall, wire insulation, countertops, caulk, roof shingle, roof felt, roof
tar, and chimney. This inspection report is not comprehensive for the entire building and does
not constitute a complete inspection of the building itself but only those materials which were
indicated by the client.
A physical assessment of each homogeneous area of suspect ACM was conducted to
assess the general condition of the material and determine the friability of the material.
Under the National Emissions Standards for Hazardous Air Pollutants (NESHAP), asbestos -
containing building materials are classified as either friable, Category I non-friable or Category II
non-friable ACM as described below:
➢ Non-friable ACM when dry, cannot be crumbled, pulverized or reduced to
powder by hand pressure.
➢ Friable ACM when dry, can be crumbled, pulverized or reduced to powder by
hand pressure.
➢ Category I non-friable ACM includes packings, gaskets, resilient floor
coverings, and asphalt roofing products containing more than 1% asbestos.
➢ Category II non-friable ACM are materials excluding Category I non -friable
ACM materials that contain more than 1% asbestos.
Bulk samples of suspect ACM were collected in general accordance with the Asbestos Hazard
Emergency Response Act (AHERA) protocols as outlined in Colorado Reg. 8 and Asbestos in
Buildings: Simplified Sampling for Friable Surfacing Materials as referenced i n the Pink Book.
Random samples of suspect building materials were collected for the specific areas and
materials identified in this report.
Surfacing materials sampled in this report include, but are not limited to overspray, and
droppings, which may be under flooring materials, adjacent walls, structural beams, and
other concealed areas.
Title 40 CFR Part 61 regulates asbestos fiber emissions and asbestos waste disposal practices
and requires the identification and classification of existing building materials prior to
demolition or renovation activity.
Building materials are historically known to contain asbestos and therefore suspected to
Page 3
contain asbestos. OSHA maintains comprehensive lists of suspect ACMs frequently encountered
during inspections.
Results
Bulk samples were submitted and analyzed by Aerobiology Laboratory, Inc. The samples
obtained were analyzed by method of Polarized Light Microscopy. Testing from this laboratory
is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) Lab Code
10189-0 for Polarized Light Microscopy (PLM).
Asbestos Containing Materials (ACM) were found and identified during the sampling conducted
at . A total of 24 samples were collected from the drywall, wire insulation, countertops, caulk,
roof shingle, roof felt, roof tar, and chimney from the bedroom, kitchen, and roof of the above
referenced residence. Of the 24 samples, 3 were detected positive for asbestos.

Recommendations
The analysis of the obtained samples indicates that there is asbestos as indicated in the table.
The amount of asbestos containing materials is less than 32sqft; therefore, the entire project
is not subject to state regulation. However, OSHA regulations will apply. Osha Regulations
may still apply to worker regulations. Any ACM, regardless of quantity, must be disposed of
as Asbestos Containing Waste. Other affected materials that did not test positive for asbestos
either prior to or following abatement by a certified general abatement company.
Page 5
Consultation with a qualified Asbestos Program Manager on the overall impact to the project
or building occupant is recommended.
If any previously unknown or undiscovered materials are found during demolition activities,
which are suspect for asbestos content then these materials should be tested for potential
asbestos content prior to continuing any further demolition work.
Disclaimer
This inspection was performed by a qualified and certified Building Inspector in the recognition
of potential Asbestos Containing Material (ACM) with approved bulk sampling techniques in
accordance with Environmental Protection Agency (EPA) and Asbestos Hazards Emergency
Response Act (AHERA). The bulk sampling was conducted on suspect ACM with a limited
number of samples being collected within the residence. This report does not imply, or
guarantee that every material on the property, or in the property building, which may
potentially have asbestos as a component, has been identified and/or sampled.
Some minor destructive sampling was conducted. 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.
Random bulk samples, representative of the suspect asbestos containing building materials
(ACBM) of each homogeneous area (HA), were collected according to the guidelines published
as EPA Final Rule: Title __ of the Toxic Substances Control Act (TSCA), 15 USC, Sections 2641
through 2654 and in compliance with 40 CFR, Part 763. Representative sampling is based on the
following criteria:
(1) The distribution of the suspect material throughout the HA.
(2) The suspect material’s physical characteristics and application.
(3) Random sampling patterns determined for each HA.
Suspect materials sampled and analyzed should be considered to be representative of materials
in each HA if:
(1) They exhibit similar physical characteristics; and
(2) The application of the sampled material can be correlated to the application of un -sampled
material.
Page 6
Bulk samples collected were analyzed utilizing the EPA’s Method for the determination of
Asbestos in Bulk Building Materials (EPA 600/R/166, July, 1993) and the McCrone Research
Institute’s The Asbestos Particle Atlas as methods references.
Suspect materials alike in appearance and application were sampled as Homogenous Areas.
These suspect materials were divided into three classifications:
(1) Surfacing material- sprayed or troweled onto structural building member
(2) Thermal System Insulation- any type of pipe, boiler, tank, or duct insulation.
(3) Miscellaneous- other suspect materials, floor tile, sheet vinyl/linoleum, ceiling tiles,
insulation, and finishing materials.
Condition assessments were performed by the accredited inspector at the time of inspection.
Condition assessments are listed in the following section. Ratings of “Good”, “Damaged”, and
“Significantly Damaged” are meant to indicate the overall condition of the material.
▪ A material in “Good” condition has no visible damage or deterioration, or showing only very
limited damage or deterioration.
▪ A material in “Damaged” condition has the following characteristics:
(1) 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 (one-quarter if the
damage is localized)
▪ A material in “Significantly Damaged” condition has one or more of the following
characteristics:
(1) The surface is crumbling or blistered over at least one -tenth of the surface if the damage is
evenly distributed (one-quarter if the damage is localized).
(2) One-tenth (one-quarter, if localized) of the material is hanging from the surface,
deteriorated, or showing adhesive failure.
(3) Water stains, gouges, or mars are over at least one-tenth of the surface if the damage is
evenly distributed (one-quarter if the damage is localized).
Accumulation of powder, dust or debris similar in appearance to the suspect material on
surfaces beneath the material can be used as confirmatory evidence.
Furthermore, identified asbestos containing materials may be in areas which are inaccessible or
hidden due to their application during the construction process and their subsequent enclosure
or covering with building and finish materials. Areas behind walls, inside chases, or other
hidden, covered or enclosed areas were not included within the scope of this inspection, as
destructive techniques would have been required to access these areas. These areas should be
inspected whenever renovation or demolition activities are scheduled which may disturb the
materials within or beneath these barriers. ‘Overspray’ or excess materials from the installation
Page 7
or application process of asbestos containing materials is common, should be expected in the
vicinity of installed asbestos containing materials, and is often present either covered by other
building materials or in hidden or unexpected locations. This inspection cannot determine the
presence of these materials and their locations and therefore the determination of these
locations and material quantities is outside of the scope of this inspection.
Bulk material samples are obtained in accordance with applicable regulations, industry
standard techniques and analyzed by a NVLAP accredited laboratory; However due to the
application and/or initial mixing process no guarantee can be made as to an ‘exact’ percentage
asbestos content (this includes ‘no asbestos detected’ and ‘trace’ contents) which represents
the entirety of the material (asbestos content fluctuations can and will occur throughout a
building material).
Please do not hesitate to contact us with any questions or concerns regarding this report or
recommendations.
