RE: Asbestos Bulk Building Inspection
2800 Meyers Road Vacant House
Oak Brook, DuPage County, Illinois
Dear Mr. Hudson
This report covers the results of the assumed asbestos inspection and analysis that JMS
Environmental Associates, Ltd. (JMS) had performed for you at 2800 Meyers Road, Oak Brook,
DuPage County, Illinois. Twenty (20) samples were analyzed for asbestos content.
Enclosed is a summary of the sample locations and results. Environmental Protection Agency
considers anything over I% to be asbestos containing. A copy of the laboratory analytical results
is also included for review. Five (5) samples were found to contain Asbestos in quantities raging
from less than I% to 10%. Please see the attached table for materials and sample locations.
Confirmed asbestos materials are required to be removed by licensed asbestos contractors prior
to any planned renovation or demolition. The asbestos flooring materials were detected
throughout the vacant house under existing carpeting and debris. The exterior bottom layers of
roofing shingles were detecting asbestos under one percent and are recommended to be disposed
and treated as asbestos waste materials. In accessible areas under floors, inside crawl space s and
in walls/ceilings are suspect to contain asbestos thermal insulation/transite ductwork and are
required to be treated as asbestos unless tested otherwise. Lead protective sheeting was observed
around the Kitchen Furnace Room and is recommended to be treated and disposed of as a lead
waste. Due to the age of the building, suspect heating oil tank(s) may be present on the site or
inside the vacant house.
The U.S. E. P. A defines a material as asbestos containing if the concentration of asbestos fibers
in greater than 1% by weight. If the quantity of asbestos is determined to be <10% by visual
estimate, the owner or operator may (1) elect to assume the amount of asbestos to be greater than
I% and treat the material as asbestos containing material or (2) request verification by point
counting technique. If a result obtained by point count is different form a result obtained by
visual estimation, the point count result will be used.
If you have any further questions, do not hesitate to contact me at JMS.

Re: Bulk Asbestos Analyses of sample(s) received 8/28/2019.

Dear Mr. Hudson,
This report 1 ,2 summarizes the results3 of the analysis of bulk material for asbestos performed by
JMS Environmental Associates, Ltd. for Village of Oak Brook. A detailed analysis report has
been included for your review.
The U.S.E.P.A defines a material as asbestos containing if the concentration of asbestos fibers is
greater than I% by weight. If the quantity of asbestos is determined to be <10% by visual
estimate, the owner or operator may (1) elect to assume the amount of asbestos to be greater than
1 % and treat the material as asbestos containing material or (2) request verification by point
counting technique. If a result obtained by point count is different from a result obtained by
visual estimation, the point count result will be used.
These sample(s) will be discarded after 3 months of their receipt unless instructed otherwise.
Should you require further assistance regarding this matter, the staff at JMS Environmental
Associates, Ltd. is experienced and licensed in all aspects of asbestos consulting. If you have any
questions regarding this report, please do not hesitate to contact us at JMS Environmental
Associates, Ltd.

ASBESTOS BULK MATERIAL ANALYSES:
This part of the report covers the results of bulk material analyses that JMS Environmental
Associates, Ltd. conducted for Village of Oak Brook. The information that is presented in this
report is representative of the sample(s) submitted to JMS Environmental Associates, Ltd.
The attached information tabulates the quantities of fibrous material found in each sample. The
numbers will not necessarily add up to 100%, with the balance being filler and binder materials.
The symbol (--) indicates not detected. A sample labeled heterogeneous indicates the possibility
of significantly higher local concentrations than the averaged value reported. If the average
asbestos content of a heterogeneous (multi -layered) sample is less than or equal to I%, but
greater than none detected (--), additional analysis by separate layers will be necessary to ensure
that no layer in the sample contains greater than one percent asbestos.
Vinyl floor tiles may contain thin fibers <0.25 µm in diameter that are below the resolution of
the polarized light microscope (PLM). The U.S.E.P.A. recommends that vinyl floor tiles
analyzed by PLM in which asbestos is not detected or detected in quantities less than or equal to
1% be verified by transmission electron microscopy (TEM). Fed. Reg. Vol. 59, No. 146, 8/1/94,
p. 38970-38971.
Sample analysis has been performed in accordance with the United States Environmental
Protection Agency's "Interim Method for the Determination of Asbestos in Bulk Insulation
Samples" as found in CFR, part763, subpart F, Appendix A and supplemented by EPA/600/R-
93/116, July 1993 — "Method for the Determination of Asbestos in Bulk Building Materials."
Analysis was initiated by a stereoscopic examination of the sample as received. Any obvious
fractions were noted and samples of each fraction were mounted for polarized light microscopy
in a 1.515 index liquid. When mounting samples, any fibrous material is thoroughly separated
for optical measurements. Classification of suspected asbestos fibers is achieved by determining
the morphology, isotropy, pleochroism, extinction angle, sign of elongation, birefringence and
refractive indices. Concurrently, the relative abundance of any asbestos material, other fibers,
fillers and binders is determined. Identification of non -asbestos material is not as rigorous as
these are not the species of interest.
Quantities measured by calibrated visual estimates are determined by comparing areal coverage
and thickness of various species present to reference material standards of known weight percent.
The quantity "<1" is reported when asbestos events are observed but determined by calibrated
visual estimate to be less than 1%.
Point count percentages are obtained by calculating the ratio of asbestos events counted to total
number of particles counted. A minimum of 400 total points is counted over 8 or more
preparations to establish statistical significance. The quantity of "< 1 " is reported when 1

to 3 asbestos events are detected within a minimum 400 -point count or when asbestos events are
observed but none are counted within a minimum 400 -point count.
The overall uncertainty of asbestos analysis is determined in part by analyzing in-house
reference material. Quantity measurements from in-house reference material can be used to
determine the accuracy of asbestos quantifying methods. The following JMS accuracy values for
critical asbestos quantities have been calculated:
Method
Quantity
of Asbestos
Accuracy of Measurement
Point Count
1.0%_10.0%
±2.0%
CVES
M-10%
±3%
When suspected asbestos fibers are observed, they are classified by measuring the following
optical properties: refractive index, birefringence, extinction angle, pleochroism, isotropy, sign
of elongation, and color. Fibers having optical properties consistent with predefined values are
classified as asbestos.
The optical properties of the various forms of asbestos are as follows:
Attached with this section of the report are the analytical results of the bulk material samples.
JMS031.BulkRpt 07/2006
Straight thin single fibers and bundles of such fibers usually with cleanly broken
Amosite:
ends on individual fibers; refractive indices of 1.664-1.686 and 1.687-1.729,
birefringence 0.020-0.033 and parallel extinction.
Thin fibers and fiber bundles with both straight and wavy sections. The ends of
Chrysotile:
bundles tend to be frayed. Indices are 1.529-1.559 and 1.537-1.576,
birefringence of 0.004-0.016 and the fibers exhibit parallel extinction.
Anthophyllite:
Similar in morphology to amosite but refractive indices of 1.606-1.648 and
1.626-1.670, birefringence of 0.013-0.025 and extinction is parallel.
Similar in morphology to amosite but is distinguished by blue to blue-green
Crocidolite:
pleochroic coloration and indices of 1.680-1.698 and 1.685-1.706. It is
commonly referred to as blue asbestos.
Transparent, elongated furrowed prisms, usually with uneven jagged ends and
Tremolite -Actinolite
smooth sides, with oblique extinction and positive elongation; indices are 1.559 -
Series:
1.612 and 1.625-1.637. The two minerals are very similar chemically and grade
into each other.
