CHECK
OF
METAL
PRODUCTS
AND
MACHINERY
AND
METAL
FINISHING
POINT
SOURCE
CATEGORY
ASSIGNMENT
In
the
RSEI
model
analysis,
some
SIC
codes
fall
in
more
than
one
point
source
category.
In
these
cases,
the
RSEI
results
are
either
distributed
among
applicable
point
source
categories
or
counted
in
each
point
source
category
in
which
they
are
regulated,
depending
on
the
specific
SIC
code.
The
majority
of
overlapping
SIC
codes
among
point
source
categories
occurs
between
the
Metal
Products
and
Machinery
(
MP&
M,
40
CFR
Part
438)
and
Metal
Finishing
(
40
CFR
Part
433)
point
source
categories.
EAD
determined
it
would
be
inappropriate
to
double
count
RSEI
model
results
for
these
SIC
codes
because
the
final
MP&
M
rule
at
§
438.1(
b)
specifically
excludes
both
metal­
bearing
wastewaters
and
wastewaters
subject
to
other
effluent
guidelines
(
e.
g.,
Metal
Finishing).
To
more
accurately
represent
the
applicability
of
these
two
point
source
categories
in
the
RSEI
analysis,
EAD
developed
a
methodology
to
distribute
the
RSEI
model
results
by
allocating
only
organic
chemical
releases
to
MP&
M
and
all
other
releases
to
Metal
Finishing.
Although
EAD
believes
this
simplified
methodology
reasonably
distributes
releases,
EPA
acknowledges
that
the
MP&
M
allocation
is
somewhat
overestimated
at
the
expense
of
the
Metal
Finishing
allocation
because
commingled
metal­
bearing
and
organic­
bearing
wastewaters
are
regulated
only
under
Metal
Finishing.

The
attached
tables
demonstrate
how
the
RSEI
model
results
for
these
shared
SIC
codes
were
distributed
between
the
MP&
M
and
Metal
Finishing
point
source
categories.

Tables
1a
and
1b
present
the
RSEI
model
rankings
values
for
the
MP&
M
and
Metal
Finishing
point
source
categories
prior
to
redistribution.
Each
table
lists
the
ranking
values
(
TRI
Pounds
Discharged
and
TWF
Hazard)
that
are
associated
with
SIC
codes
that
belong
only
to
that
point
source
category,
as
well
as
SIC
codes
that
are
shared
between
the
two
point
source
categories.
These
values
sum
to
the
total
ranking
value
prior
to
redistribution.
Note
that
there
are
no
ranking
values
associated
with
SIC
codes
that
belong
only
to
MP&
M;
this
is
because
every
SIC
code
that
falls
within
the
MP&
M
point
source
category
also
falls
under
Metal
Finishing.

Tables
2a
and
2b
present
SIC
codes
and
their
associated
point
source
categories.
Table
2a
lists
those
SIC
codes
that
fall
under
both
the
MP&
M
and
Metal
Finishing
point
source
categories;
ranking
values
from
these
SIC
codes
were
redistributed
as
demonstrated
in
this
document.
Table
2b
lists
those
SIC
codes
that
fall
under
Metal
Finishing
but
not
under
MP&
M;
ranking
values
from
these
SIC
codes
remain
under
Metal
Finishing.
As
stated
above,
there
are
no
SIC
codes
belonging
to
MP&
M
and
not
Metal
Finishing.

Table
3
presents
all
chemicals,
along
with
the
associated
ranking
values,
that
are
discharged
from
facilities
within
the
Metal
Finishing­
only
SIC
codes
listed
in
Table
2b.
The
summed
ranking
values
from
these
chemicals
constitute
part
of
the
final
point
source
category
ranking
values
for
Metal
Finishing
(
to
these
were
added
the
redistributed
values
from
shared
SIC
codes).

Table
4
lists
the
chemicals
that
are
expected
to
be
controlled
by
the
MP&
M
regulation.
MP&
M
regulates
only
direct
discharges;
therefore,
when
calculating
the
ranking
values
to
be
redistributed
to
MP&
M,
EPA
considered
direct
discharges
of
the
chemicals
in
Table
4
from
the
shared
SIC
codes
in
Table
2a.

Table
5
lists
the
ranking
values
for
all
chemicals
discharged
from
the
shared
SIC
codes
in
Table
2a,
broken
out
by
discharge
destination
(
i.
e.,
direct
vs.
POTW
transfer).
The
ranking
values
associated
with
direct
discharges
of
the
chemicals
in
Table
4
(
these
values
are
presented
towards
the
top
of
the
table)
were
summed
to
create
the
ranking
values
for
the
MP&
M
Point
Source
Category.
Ranking
values
associated
with
all
other
discharges
from
these
SIC
codes
were
distributed
to
the
Metal
Finishing
Point
Source
Category.
