Subject
Report
on
chat
applications
by
Mr.
Richard
Adams,
Flint
Rock
Applications,
Picher,
OK.

I
just
spoke
with
Mr.
Richard
Adams
from
Flint
Rock
Products,
a
Pitcher,
OK­
based
company
(
Tel:
918­
673­
1737).
This
is
to
acknowledge
my
recent
telephone
conversation
with
Mr.
Adams
and
to
express
my
appreciation
for
the
information
he
kindly
provided
me.
As
discussed,
we,
at
the
USEPA's
Office
of
Solid
Waste
collect
the
information
as
part
of
our
Congress­
mandated
Transportation
Bill
(
Section
6006)
task
of
issuing
guidelines
on
the
beneficial
use
of
chat
in
the
"
Tar
Creek
Mining
District
of
Oklahoma".

Flint
Rock
Applications
screen
their
washed
tar
into
two
size
fractions:
3/
8"
chips
and
sand­
size.
Mr.
Adams
has
been
using
as
a
guideline
400
ppm
total
lead
concentration,
but
is
not
aware
of
any
leach
concentration
requirements/
standards.
His
company
markets
about
95%
of
its
washed
chat
for
ultimate
application
in
asphalt.
The
reminder
is
marketed
for
the
following
applications:

(
1)
As
a
component
in
nonskid
surfaces:
­
On
bridge
roadway,
as
two
layers
sandwiched
between
epoxy
layers
­
For
stairsteps
in
industrial
warehouses
and
parking
garages
(
2)
As
sand
blasting
material
(
3)
As
rough
coating
for
drill
rigs
and
gas/
oil
pipes,
both
domestically
and
in
Saudi
Arabia
(
4)
For
waste
water
sewer
filter
rock.

­
They
have
currently
a
$
50,000
prize
contest
for
propositions
on
new
uses
of
chat
­
They
contracted
with
the
Civil
Engineering
Department,
Univ.
of
Missouri,
Columbia,
for
a
study
of
cement/
concrete
applications;
so
far
the
study
has
not
materialized
­
Mr.
Adams
believes
that
the
barrier
for
cement
applications
of
chat
stems
from
the
absence
of
experimental
data
­
Mr.
Adams
believes
that
his
company
has
provided
chat
for
a
recent
Native­
American­
owned
enterprise
that
intended
to
test
its
appropriateness
for
the
manufacturing
of
ceramic
and
counter­
top
products.

Mr.
Adams
­
I
would
sincerely
appreciate
if
you
could
provide
us
with
the
name/
contact
information
of
your
University
of
Missouri
contact
so
we
can
talk
to
him
about
the
state
of
knowledge
regarding
the
use
of
chat
in
concrete
applications.

Please
correct
me
if
I
misconstrued
or
omitted
some
of
the
information
you
have
relayed
to
me.
