Introduction
The
MACT
floor
for
wastewater
originally
evaluated
all
wastewater
streams
in
a
single
group.
1
Public
comments
on
the
proposed
rule
suggested
that
wastewater
streams
that
contain
only
soluble
HAP
should
be
considered
separately
from
all
other
streams
(
i.
e.,
those
containing
partially
soluble
HAP
or
a
mix
of
partially
soluble
and
soluble
HAP).
This
memorandum
presents
the
results
of
the
analysis
of
wastewater
streams
that
contain
partially
soluble
or
mixed
HAP
compounds.
The
results
of
the
analysis
of
streams
that
contain
only
soluble
HAP
is
presented
in
a
separate
memorandum.

II.
Discussion
Of
the
364
wastewater
streams
in
our
database,
192
streams
at
45
facilities
contain
only
partially
soluble
HAP
or
both
partially
soluble
and
soluble
HAP
compounds.
Table
1
summarizes
the
results
from
various
queries
for
these
streams.
As
in
the
previous
analysis,
this
analysis
shows
that
more
than
12
percent
of
the
wastewater
streams
with
partially
soluble
and
mixed
HAP
concentrations

10,000
ppmw
(
at
any
flow)
are
managed
and
treated
using
HON­
equivalent
procedures.
Both
analyses
also
indicate
that
more
than
12
percent
of
the
wastewater
streams
containing
partially
soluble
and
mixed
HAP
concentrations

1,000
ppmw
and
<
10,000
ppmw
at
flowrates

10
lpm
are
managed
and
treated
to
a
level
consistent
with
the
HON
requirements.
Unlike
the
previous
analysis,
however,
this
analysis
also
shows
that
more
than
12
percent
of
the
streams
with
concentrations
in
this
range
and
flows
as
low
as
1
lpm
are
managed
and
treated
in
a
manner
consistent
with
the
HON
(
i.
e.,
5
of
30
streams
in
this
range).
At
flows
lower
than
0.5
lpm,
only
one
stream
is
managed
and
treated
to
this
level.
Therefore,
we
would
set
the
floor
for
wastewater
streams
that
contain
partially
soluble
HAP
as
HON­
equivalent
management
and
treatment
for
streams
that
contain

10,000
ppmw
at
any
flow
or
that
contain

1,000
ppmw
and
<
10,000
ppmw
at
a
flow

1
lpm.
All
wastewater
streams
in
our
database
that
contain
partially
soluble
or
mixed
HAP
in
concentrations
between
1,000
ppmw
and
10,000
ppmw
are
presented
in
Attachment
1.
All
wastewater
streams
that
contain
partially
soluble
or
mixed
HAP
in
concentrations
greater
than
or
equal
to
10,000
ppmw
are
presented
in
Attachment
2.
