1.0 INTRODUCTION
Serpentine rock containing a small but significant percentage of chrysotile
is being mined and processed for road stone in a large quarry in Montgomery
County outside Rockville, Maryland. The asbestos-bearing stone has been and
is principally used in asphalt concrete but, in the past, has also been used
in an unbound form for road surfacing and other similar uses. When this stone
is used without a binder on roadways, asbestos fibers are liberated and become
airborne in the dust generated by wind, traffic vehicles, and road surface
activities. Air sampling has shown asbestos fibers in the ambient air up to
100 meters from unpaved roads using stone from this quarry. Also, concentra-
tion of chrysotile asbestos fibers in the atmosphere near unpaved roads measured
up to 1000 times higher than normal urban background concentrations.
Asbestos is a known carcinogen. In 1971, EPA designated asbestos as a
hazardous pollutant and proposed a national emission standard for several
sources of asbestos. Since then, EPA has promulgated a hazardous emission
standard for those sources of asbestos and has amended the standard to apply
to other sources as new data became available. (See 40 CFR, Part 61, Subpart B.)
EPA will continue to include additional sources as warranted. Now EPA has,
therefore, decided to study the crushed stone industry to determine those
quarries which produce crushed stone containing asbestos fibers, the asbestos
content of the crushed stone being produced, and the ambient air concentration
due to the use of such crushed stone.
Asbestos is a generic term for certain hydrated silicates, which, when
crushed, separate into millions of fibers. See Appendix A for geological
definitions as used in this report. Exposure to airborne asbestos fibers is
directly related to human disease, such as pulmonary fibrosis, carcinoma, and
pleura! mesothelioma. Mesothelioma is a rare cancer of the lining of the
chest cavity or abdomen, for which asbestos is the only known cause. The
latency period of mesothelioma is believed to be 20 to 40 years. The risk in
contracting mesothelioma is greatest among asbestos workers, and to a lesser
degree there appears to be some risk in nonoccupational exposures. No epidemio-
logical evidence exists that asbestos fibers from stone used in road surfacing
have caused mesothelioma or lung cancer; however, because of the long latency
period, little evidence is expected yet.

2.0 GEOLOGICAL BASIS IN SELECTING QUARRIES
The mineralogy of rocks found in some portions of the United States
suggests that there may be a number of rock quarries producing chrysotile
asbestos-bearing stone. The rock type (serpentinite) that occurs in Montgomery
County also occurs in places from Maine to Alabama throughout much of the
Appalachian Mountains and some portions of the western coastal ranges. United
States Geological Survey (USGS) geological maps, United States Bureau of Mines
(BOM) quarry maps, and quarry assessments from State geologists have been used
by EPA to list quarries with potentially chrysotile asbestos-bearing stone.
Other areas may contain other types of asbestos (amphiboles) but more geologi-
cal information is available of the locations of serpentinite mineral which
almost always contains at least a small percentage of chrysotile. EPA is
concentrating on chrysotile for the initial assessments.
The procedure originally proposed by EPA to locate crushed stone quarries
that may contain chrysotile was to "match" known deposits of serpentinite and
other ultramafics to quarry locations by using transparent map overlays. Any
quarry within a 5-mile radius of a known deposit would then be recorded as a
site with the potential of containing chrysotile.
The maps showing ultramafic deposits on the East Coast were those of the
USGS [1,2]. Overlays of quarry locations at the same scale as the USGS maps
(1:500,000) were provided by the Bureau of Mines. These overlays were supple-
mented by both State Aggregate Association maps and the National Emissions
Data System (NEDS) quarry location coordinates. The Bureau of Mines performed
field checks of some of the quarries on their overlays and determined that the
exact locations were as much as 10 miles from the locations indicated on the
overlays [3]. For this reason, a 10-mile radius was adopted.
The West Coast geological maps consisted of a USGS base map of the
United States and a USGS overlay indicating the positions of the undifferen-
tiated ultramafic rock deposits. The scale of these maps was much smaller
than the East Coast maps (approximately 1:2,500,000). The BOM quarry location
overlays were on a different scale (1:3,100,000) and had to be enlarged.
EPA sent letters to State geologists in those States that contained
ultramafic rock deposits. From the information obtained from State geolo-
-------
gists, it became apparent that serpentinite was in eight quarries. Samples
from these quarries were sent directly to the Illinois Institute of Technology
Research Institute for transmission electron microscopic examination. In the
letters, the geologists were asked to provide geologic information on specific
quarries and comment on the procedure of matching deposits to quarry locations
'within a 5-mile radius. Of the many letters that were received in response,
three discussed the procedure.
The response of the North Carolina State Geologist was as follows:
"The use of BOM maps and USGS maps 1-476 and 1-676 showing serpentinite
rock deposits is a valid and viable method for targeting quarries with a
potentially hazardous asbestos content. Although the maps are somewhat
generalized, the method of investigating quarries within a 5-mile radius
of serpentinite bodies should adequately compensate for this generality
[4].
The response of the California State Geologist was as follows:
"The method of examining all quarries within 5 miles of serpentinite rock
deposits should catch all (or nearly all) 'asbestos-bearing1 sites in
California" [5].
The response from Oregon implied potential problems.
"Procedures for locating potential serpentinite crushed stone operations
as outlined appear adequate for developing general conclusions. They are
inadequate for comprehensive sampling owing to the possibilities of
errors and oversights in small-scale base maps and data bases" [6].
The procedure proposed by EPA used deposits of serpentinite and ultrama-
fics as the base point. As pointed out by the Oregon response, there may be
"...errors and oversights in small-scale base maps and data bases." Keeping
this statement in mind and examining the trend of indicated deposits, RTI
suggested that a "belt approach" be adapted to the matching procedure. This
is based on the tendency of ultramafic rocks to occur mostly in mountain belts
that have long, narrow area geometries so that deposits of like characteristics
are distributed throughout the elongated area or belt. The belt approach
requires that all quarries in a belt be included in the field survey.
-------
To further justify this suggestion, larger-scale State geological maps
were compared to the smaller-scale USGS base maps. This comparison supported
the suggestion by locating very small serpentinite deposits that did not show
on the smaller-scale maps. In most cases, these smaller deposits were in the
same geologic formations as those larger deposits shown on the smaller-scale
maps. From this information, it was inferred that more deposits, which had
not been previously located, could exist in these formations. These formations
also followed the trends established by the deposits on the smaller-scale
maps.
For example, the assessment of the State of Vermont is described in
detail. On the Larrabee map [2], many occurrences of ultramafic rocks,
including serpentinite, dunite, and peridotite, and highly variable or undivided
ultramafics, are shown trending NS between 72° and 73° W longitude. Serpentin-
ite deposits, which include talc and chrysotile, are found in this belt.
On the Vermont State Geological Map [7], ultramafics occur in three
separate map units: (1) serpentinite, carbonate rock, talc-carbonate, and
steatite (map symbol us); (2) dunite, peridotite, and serpentinite (udp); and
(3) undifferentiated ultramafic rocks (uu). The first two, LJS and udp, are
the most important with regard to number of occurrences and extent of the area
over which they are found.
The ultramafics, especially Ujs and udp, occur primarily in four rock
units. In the first, ij§ and udp occur in the Hazens Notch formation (Eh) of
interbedded carbonaceous and noncarbonaceous quartz-sericite-albite-chlorite
schist that grades to quartzite and gneiss. The Eh trends NS from 45° N
latitude (the Canadian border) to approximately 43°45' N latitude. The
indicated deposits are scattered throughout JEh above 44°15' N but mostly from
44°45' to 45° N.
In the Ottauquechee formation (Eo), LJS_ occurs north of 44°45' N. The £o
is a black carbonaceous phyllite or schist that lies next to and parallels
Eh.
In the Stowe formation (OEs), us; and udp are dispersed throughout this
quartz-sericite (muscovite-paragonite)-chlorite phyllite and schist. The OEs
parallels Eh and E_o and runs the entire length of the State, thinning out near
the Massachusetts border.
-------
In the Missisquoc formation (Omm), LJS and udp occur south of approxi-
mately 43°30' N latitude. At approximately 43° N latitude and 72°45' W longi-
tude, a large mass (1/2 mile wide and 3 1/2 miles long) of ^JS_ and udp occurs.
The Omm is a quartzite and quartz-plagioclase granulite that parallels the
other formations and runs the entire length of the State.
An examination of the Vermont map shows these four formations and their
associated ultramafics running in a NS band from the Canadian border (45° N
latitude) to the Massachusetts border (42°45' N latitude). The belt including
these formations is approximately 16 miles wide at 45° N and thins to about
6 miles at 42°45' N. The maximum width of the belt is about 22 miles.
For the State of Vermont, and similarly for other States, RTI suggested
that the area of concern be broadened to include this belt running north to
south in the State. Using this belt approach and the 10-mile radius to com-
pensate for uncertainties in quarry locations certainly increases substantially
the number of quarries to be investigated. However, this procedure is justified
on the basis of insuring adequate coverage of the potential problem areas.
In the State of Oregon, the Bureau of Mines maps do not show the large
number of quarries that are listed by the State Geological Department and the
Mining Enforcement and Safety Administration. As a result, the estimated
number of quarries in these belts has a large degree of uncertainty. There-
fore, EPA contracted with RTI to obtain more detailed quarry locations and
geologic maps for Oregon. For Alaska, State officials suggested on site
inspections. RTI contracted with the State Division of Geological and Geophysi-
cal Surveys to inspect and obtain stone samples from 16 quarries located near
suspected serpentinite deposits.
With this information, 111 quarries (not including Oregon and Alaska)
were initially identified as producing rock that potentially contains chrysotile
asbestos as a result of being located within or near serpentinite belts. Of
the quarries on this list, 90 participated in the study to varying degrees.
Twelve quarries are no longer in operation, and the crushed stone from five
quarries is used in products in which the stone is in bound form. For four
quarries, the location, name, or owner/operator were substituted by another.
The remaining quarries could not be identified with the name or location
-------
corresponding to the information obtained from BOM or did not participate in
the study, but none were relieved from complying with EPA requests. During
the course of the study, the examination of crushed stone samples from 16
quarries in Alaska and 20 quarries in Oregon were added to the scope of work.
3.0 DESCRIPTION OF PETROGRAPHIC EXAMINATION
The analytical procedures used in this study were established to deter-
mine the presence of serpentinite rock (especially chrysotile) and amphibole
asbestos (i.e., cummingtonite asbestos, grunerite asbestos, anthophyllite
asbestos, crocidolite, tremolite asbestos, actinolite asbestos, and holmquistite),
In this study these procedures are intended primarily to be qualitative.
However, quantitative estimates of concentration may be made in those samples
where the concentration is sufficiently high. Obtaining more precise quantita-
tive data requires more sophisticated and specialized equipment, such as an
electron microscope.
The standard analytical techniques for geological examination of minerals
fall into two broad categories—megascopic and microscopic examination.
Megascopic examination is related to observations made with the unaided eye
and with a microscope under low magnification, typically less than x30. Used
by a trained geologist, this method can provide a reliable and rapid means of
identification of many mineral types.
Microscopic examination is performed with the aid of one or more special
types of microscopes. The magnification range employed is typically from x30
to xiOOO. Microscopic examination is routinely used to obtain data which
cannot be recovered from megascopic techniques. In those cases where identi-
fication of some minerals cannot be accomplished megascopically or in those
samples where the mineral concentration is low, positive identification using
microscopic examination generally requires the preparation of thin sections.
Preparation of a thin section requires trained personnel using special
techniques. In this process the sample is mounted firmly to a glass microscope
slide and then reduced in thickness to approximately 0.03 mm by grinding and
finally by carefully polishing. The specimen is sufficiently thin for light
to be transmitted through the sample with only slight attenuation, and to be
-------
detected through the microscope. The crystallography and, to a degree, the
composition of a mineral influences the behavior of the transmitted light.
Using a specially designed microscope to measure properties such as index of
refraction, polarization, absorption, and crystalline form, most minerals in
the specimen may be identified. This permits more exact identification, and
quantitative estimates may also be made.
3.1 Test Samples
The procedure for reducing field samples to testing size is formalized in
the American Society for Testing Materials (ASTM) standard designated C702-
71T. The procedure given in the standard is employed to minimize variations
between the test sample and the field sample in the identification of minerals
during petrographic examination.
The ASTM procedure provides for using a mechanical splitter according to
Method A, or by quartering according to Method B, to reduce field samples to
testing size. The application of Method B requires that the particle surfaces
be free of moisture. If particle surfaces are covered with moisture, the en-
tire field sample may be dried to at least the surface-dry condition, prior to
quartering, but the temperature used during drying will not exceed those used
for any of the tests contemplated.
The photographs given in Figures l(a) through l(d) show the details of
the quartering procedure used in this study. Figure l(a) shows a dry field
sample being placed on a clean, clear plastic sheet. Beneath the plastic
sheet are two metal rods rigidly fastened at a 90° angle to each other. Ini-
tially the rods are used to flatten the field sample so that the ratio of the
diameter to its thickness is 8:1 as shown in Figure l(b). The rods are then
lifted up to 1 inch above the table top in order to separate the field sample
into quarters as is shown in Figure l(c). Opposite quarters are scooped up
using a clean shovel and are placed in clean, clear plastic bags, one of which
is shown in Figure l(d). In addition, the "fines" for one sample are separated
out for special study. The "fine" material is sieved and that portion which
passes through 100 mesh screen, but does not pass through 150 mesh screen, is
retained for further examination. The "fines" are placed in a smaller, separate,
clean, clear plastic bag. This smaller bag is placed in the larger bag contain-

ing the test sample. Each of the two reduced samples are appropriately
labeled as shown in Figure l(d).
3.2 Megascopic Examination Procedure
The procedure used in this study to conduct petrographic examination is
given in Table 1. For megascopic examination, no further sample preparation
beyond quartering and sieving is required. Megascopic examination is assisted
by the use of a low power (*15, X20, x30) binocular microscope. The megascopic
examinations are conducted by a trained geologist.
The photograph in Figure 2(a) shows the geologist removing the small
plastic bag containing the fines from the larger plastic bag, which contains
the larger test sample. In the photograph in Figure 2(b), the geologist is
conducting the visual examination of the test sample and selecting pieces for
further study.
Figures 2(c) and 2(d) show the megascopic examination with the aid of a
needle point. The needle point aids in determining the relative hardness of
minerals present in the rock sample and to aid in examination of mineral
cleavage. This examination results in the determination of the following,
sample properties: rock texture (size, shape, and arrangement of minerals);
color, streak, hardness, number, and relative orientation(s) of cleavage
planes; and the shape of minerals contained within the sample. From these
data and knowledge of mineral associations, the identification of many miner-
als may be made with a high degree of confidence.
3.3 Microscopic Examination Procedure
The microscopic examination of samples employed in this program included
the examination of received crushed stone, "fines" or sieved fractions, and
thin sections. Table 1 presents the information relating to these tests. The
indices of refraction and extinction angle obtained are quantitative. Other
observations such as color, form, etc., are qualitative. The quantitative
data provide a basis on which more precise identification may be made.
Figures 3(a) to 3(c) show the examination of a dry sieved sample. This
examination results in qualitative data. Figures 4(a) to 4(d) show the sieved
sample preparation using an index oil. By using two or more index oils, the
indices of refraction may be determined to a precision of ± 0.005. Figure
4(a) shows the geologist placing a drop of index oil on a glass slide, 4(b)

Figure 5(a) shows the geologist examining a sample utilizing a petrographic
microscope. The petrographic microscope is used to study both sieved and thin
section samples. While it is used for general observations, its features
permit the measurement of indices of refraction and the extinction angles.
Therefore, more precise identification may be made.
The preparation and examination of thin sections is restricted to those
cases where magascopic and microscopic examination of sieved samples cannot
make positive identification. This restriction arises because of the cost in
preparation required for thin sections. The criteria used in deciding whether
thin section examination should be made are as follows:
1. When fibrous material (asbestiform) is observed or if such minerals
as tremolite, actinolite, serpentinite, riebecbite, grunerite,
cummingtonite, and anthophyllite are present in the sieved sample
under examination, but an asbestiform variety is not identified.
2. When the minerals present cannot be identified.
3.4 Properties of Asbestiform Minerals
In this section we describe the properties of asbestiform minerals used
in this study to identify presence of such minerals.
Table 2 lists two sets of properties used in megascopic examination to
identify asbestiform minerals. The first set relates to serpentinite rock
formations. The serpentine mineral group includes, primarily, the three min-
erals antigorite, lizardite, and chrysotile. These minerals may occur as
separate entities or in natural mixtures. In this study only the identifica-
tion of chrysotile is considered, since it is the only mineral in this group
that is fibrous. Moreover, chrysotile is more easily distinguished from other
minerals than are antigorite and lizardite.
The second set relates to the amphibole group minerals. 'The amphibole
asbestiform group includes the minerals tremolite, actinolite, anthophyllite,
cummingtonite, grunerite, crocidolite, and holmquistite. Other mineral groups
are present in the amphiboles. These groups usually do not appear in asbesti-
form varieties and have not been used commercially as asbestos.

list of properties, given at the top of Table 3, shows a steady progression of
increasing confidence in mineral identification from index of refraction
through to pleochroism. The last column lists the asbestiform minerals.
4.0 SUMMARY OF RESULTS
In this section and in Appendix B the results of the study are summarized
and briefly discussed. Tables 4, 5, 6, and 7 summarize the results of the
petrographic examinations of crushed stone samples submitted by the quarries.
Appendix B contains one form for each quarry that submitted samples. Each
form contains the observations made by the petrographer on the examinations of
all samples examined for a quarry.
The quarries are placed in four groups. The first group listed in Table 4
contains the quarries that were selected because of their close proximity to
suspected asbestos-bearing stone, within the continental United States, except
those located in Oregon, Alaska, and Pennsylvania. Table 5 lists suspected
quarries located in Alaska, Table 6 gives those in Oregon, and Table 7 shows
miscellaneous quarries.
Each form in Appendix B summarizes the petrographer1s observations of one
quarry on samples examined from that quarry. The summary includes the minerals
identified and other significant optical properties relating to asbestiform
minerals. However, the summary does not specify the type of examination
conducted—megascopic, microscopic, and thin section—in the determination of
the minerals identified. These summary sheets form the basis of the informa-
tion placed in Tables 4, 5, 6, and 7.
The observations and the backup data documentation for the summaries,
which appear in Appendix B, are the sum of the petrographer1s observations for
each quarry. For each examination conducted on a test sample, which was
obtained from a field sample, the petrographer records his observations on a
standard form. In the interest of brevity, the information contained on the
standard form is not included in this Final Report.
The summary comments for each quarry given in Tables 4 through 7 are
limited to the asbestiform minerals identified, or if the quarry is no longer
in operation, or if the quarry owner/operator chose not to participate in the
study. As described above, the summaries in Appendix B provide more detailed
information relating to petrographic examinations and any qualifying statements.

5.0 CONCLUSIONS AND RECOMMENDATIONS
Petrographic examinations conducted on crushed stone samples submitted by
certain quarries show evidence of containing serpentinite, and a larger
number show evidence of containing amphiboles. More than one-half of the
quarries submitted crushed stone samples that do not show evidence of contain-
ing either serpentinite or amphiboles. In all cases in which there is evidence
of the presence of serpentinite and/or amphiboles, further investigation is
recommended. This investigation should include, at least, obtaining samples
that represent the entire quarry, and the examination of the stone samples by
means of transmission electron microscopy. Those quarries that did not
comply completely with EPA requests should be investigated further.

APPENDIX A
GEOLOGICAL DEFINITIONS
Actinolite—
An iron-rich amphibole.
Amphibole—
A mineral group, general formula A2-3B5(SI,A14)011-(OH)2, where A is
mainly Mg, Fe", Ca, and Na; B is mainly Mg, Al, and Fe".
Anthophyllite—
Contains less iron than cummingtonite and may have Fe and Ca (syn.
bidalotite).
Antigorite—
A platy or lamellar, brownish-green mineral of the serpentine group (syn.
picrolite, baltimorite).
Asbestiform—
Said of a mineral that is fiberous, i.e., like asbestos.
Asbestos--
(a) A commercial term applied to a group of highly fiberous silicate
minerals that readily separate into long, thin, strong fibers of
sufficient flexibility to be woven, are heat resistant and chemically
inert, and possess a high electric insulation, and therefore are
suitable for uses (as in yarn, cloth, paper, paint, brake linings,
tiles, insulation, cement, fillers, and filters, where noncombustible,
nonconducting, or chemically resistant material is required.
(b) A mineral of the asbestos group, principally chrysotile (best adapted
for spinning) and certain fiberous varieties of amphibole (esp.
tremolite, actinolite and crocidolite).
(c) A term strictly applied to the fiberous variety of actinolite.
Chrysotile—
A lavender-blue, indigo-blue, or light-green asbestiform variety of
Riebeckite (syn. Krokidolite).
Cummingtonite—
Contains more iron than anthophyllite, may have Mn and Zn.
Gedrite—
An aluminum-bearing variety of anthophyllite.
33
-------
Grunerite—
An iron-rich variety of cummingtonite.
Immersion Liquid—
A liquid of known refractive index that is used in the immersion method
of determining a mineral's refractive index. An example is autone.
Immersion Method—
A method of determining the relative refractive index of a mineral in
order to identify it, by immersing the sample in a liquid of known refrac-
tive index.
Index of Refraction—
In crystal optics, a number that expresses the ratio of the velocity of
light in vacvo to the velocity of light within the crystal. Modifying
factors include wavelength, temperature, and pressure. Birefringent
minerals have more than one index of refraction.
Mineral —
A naturally formed chemical element or compound having a definite chemical
composition and, usually, a characteristic crystal form. Minerals are
usually inorganic.
Petrographic Microscope—
See polarizing microscope.
Polarizing Microscope—
A microscope that uses polarized light and a revolving stage for analysis
of petrographic thin sections. Two prisms, one above and the other below
the stage, polarize and analyze the light, the stage rotates about the
1ine-of-sight axis.
Riebeckite—
A blue or black (Na-bearing) momoclinic amphibole.
Rock--
Any naturally formed, consolidated or unconsolidated material (but not
soil) composed of two or more minerals, or occasionally of one mineral,
and having some degree of chemical and mineralogic consistency; also a
representative sample of such material.
Serpentine—
The name includes at least two distinct minerals, antigorite and chrysotile,
very difficult to distinguish. Most asbestos is chrysotile.
Splitting--
The sampling of a large mass of loose material by dividing it into two or
more parts, e.g. quartering.
34
-------
Thin Sectiorr-
A fragment of rock or mineral mechanically ground to a thickness of
approximately 0.03 mm, polished, and mounted between glasses of a microscope
slide. This reduction renders most rocks and minerals transparent or
translucent, thus making it possible to study their optical properties.
Tremolite—
A mineral of the amphibole group described by the general formula
Ca2Mg5Si8022(OH)2.

16. ABSTRACT
Mineralogical analysis was conducted on crushed stone samples from quarries
located in suspected serpentinite belts. Ninety-four quarries located within the
conterminous United States participated in this study including seven from Oregon,
three additional quarries in California, and one from Pennsylvania. In addition, 16
quarries from the state of Alaska also participated in the study.
The study used megascopic and microscopic examination to identify those quarries
in which the crushed stone produced contains serpentinite and amphiboles. There were
42 quarries in which asbestiform materials were identified or that the results of the
petrographic examinations suggested the presence of asbestiform materials. There
were 10 quarries in which serpentinite was identified.
