Everyone,

We
have
some
new
information
we
will
present
in
the
meeting
tomorrow.
The
EPA
data
in
the
CWT
Development
Document
was
collected
from
a
single
CWT
facility
and
used
to
support
the
claim
of
over
50%
removal
of
molybdenum
at
a
organics
subcategory
facility
is
based
on
five
effluent
and
four
influent\
samples.
This
data
is
attached
to
the~
agenda,
transmitted
separately.

The
five
effluent
samples
are
almost
exactly
the
same,
having

and
very

on
the
fourth

On

The
effluent
that
was
higher
in
concentration
than
influent
is
due
1
to
higher
influent
concentration
on
days
preceding
the
sampling.
Similarly,
the
effects
of
the
high
influent
on
the
effluent
have
not
yet
­
occurred.

The
same
lead/
lag
effects
can
be
observed
in
the
June203
data
from
Clean
Harbors.
The
data
does
not
demonstrate
effective
removal.
Molybdenum
is
not
suitable
as
a
measure
of
effective
treatment
and
should
be
deleted
from
the
CWT
rule.
