Summary:
On
June
20,
Mr.
Eickhoff
returned
a
call
I
made
earlier
to
him
regarding
follow
up
information
on
methanol­
containing
wastewater
streams
at
the
facility.
In
the
Section
114
information
request
filled
out
by
the
facility
in
June
of
1997,
several
methanol­
containing
wastewater
streams
were
reported
as
being
generated,
managed
and
treated.
These
were
reported
as
W002,
W003,
and
W005.
I
contacted
the
facility
to
verify
some
information
regarding
these
streams.
My
questions,
and
Mr.
Eickhoff's
responses
are
presented
below.

1.
Is
the
process
generating
these
streams
still
operating?

No.
The
facility
no
longer
manufactures
the
product
that
used
methanol.

2.
Were
any
other
HAP
contained
in
the
3
wastewater
streams(
W002,
W003,
and
W005)
of
interest?

Mr.
Eickoff
reported
that
some
xylene
could
have
been
present
in
all
three
of
the
streams,
although
methanol
is
the
primary
HAP
in
the
streams.
Mr.
Eickoff
estimated
the
concentration
of
xylene
in
these
streams
as
less
than
1%
by
weight
(
10,000
ppmw).
By
contrast,
the
expected
methanol
concentration
is
20%
by
weight.

3.
Were
the
streams
hardpiped
to
treatment?
Contact
Report
Yes,
the
streams
are
hardpiped
to
an
equalization
tank
(
a
covered
tank)
prior
to
discharge
in
the
POTW.
The
treatment
system
consists
of
using
air
radial
jet
mixers
(
spargers)
to
strip
material
out
of
the
water.
This
air
stream
is
incinerated.

4.
Was
the
process
used
to
generate
the
wastewater
a
batch
process?
Yes,
all
processes
at
this
facility
were
and
continue
to
be
batch.
