The
purpose
of
this
note
is
to
document
the
nature
and
scope
of
consultation
USEPA
had
with
the
Materials
Division
of
the
Oklahoma
Department
of
Transportation.
An
initial
telephone
teleconference
was
held
with
OKDOT
on
September
14,
2005
with
Reynolds
Toney,
Morris
Bell,
Scott
Seiter,
Danny
Gierhart,
and
Kenny
Seward
all
of
the
Materials
Division.
I
introduced
the
basic
elements
of
the
rule
and
requested
information
from
ODOT
regarding
the
current
use
of
chat
in
asphalt
and
concrete
pavement.
ODOT
indicated
that
the
state
has
published
highway
design
specifications
and
that
it
was
their
experience
that
chat
may
not
be
a
good
aggregate
substitute
in
concrete.
ODOT
also
pointed
out
that
they
were
aware
of
chat
being
used
in
hot
mix
asphalt
and
that
up
to
25
percent
of
aggregate
could
be
substituted
for
other
aggregates.
I
indicated
that
I
would
provide
ODOT
versions
of
the
draft
rule
as
time
allowed.

I
conducted
follow­
up
telephone
calls
with
Scott
Seiter
approximately
once
a
month
from
September
through
January.
I
also
sent
Scott
versions
of
the
draft
rule
and
sought
comment
from
ODOT.
ODOT
has
been
very
cooperative
and
replied
to
all
of
EPA's
requests
for
data.
