This
memorandum
discusses
the
Standard
Industrial
Classification
(
SIC)
codes
for
facilities
in
the
subcategories
for
the
effluent
limitations
guidelines
and
standards
for
the
Nonferrous
Metals
Manufacturing
Point
Source
Category
(
40
CFR
Part
421).
It
reviews
the
primary
SIC
codes
for
the
nonferrous
metals
manufacturing
(
NFM)
industry,
lists
the
subcategories
in
the
Part
421,
and
presents
the
SIC
code
assigned
to
each
subcategory
for
the
review
of
pollutant
loads
for
the
nonferrous
metals
manufacturing
industry
that
was
conducted
during
the
development
of
the
2004/
05
304(
m)
plan.

There
are
31
subcategories
in
the
effluent
limitations
guidelines
and
standards
for
the
nonferrous
metals
manufacturing
industry.
Although
facilities
with
different
SIC
codes
can
perform
operations
subject
to
Part
421,
the
primary
SIC
codes
for
facilities
subject
to
the
NFM
effluent
limitations
guidelines
and
standards
are:


A

and

SIC

includes
several
operations
covered
by
Part
421,
including
the
production
of
bauxite,
refined;
alumina;
uranium,
slug
(
radioactive);
liquid
metals;
and
several
metals,
inorganic.
ERG
used
discharge/

System
(
PCS)
and
2000
Toxic
Release
Inventory
(
TRI)
databases
along
with
data
available
on
the
Internet
to
determine
which
facilities
in
SIC
Code
2819
performed
operations
covered
by
Part

The
following
facilities
with
SIC
Code
2819
listed
below
are
known
to
perform
NFM
manufacturing
operations:


ALCOA
World
Alumina
in
Texas
(
TRI);


ALCOA
World

Florida
(
TRI);


ALCOA
World

(
TRI
and
PCS);


U.
S.
Enrichment
Corp
in
Ohio
(
PCS);
and

Reynolds

Co
in
Arkansas
(
PCS).

Pollutant
loads
for
these
facilities
are
included
in
the
pollutant
loads
for
the
NFM
manufacturing
point
source
category.

The
following
table
presents
the
SIC
codes
assigned
to
facilities
in
each
of
the
subcategories
for
the
nonferrous
metals
manufacturing
point
source
category.
As
shown,
one
subcategory
was
assigned
to
SIC
code
2819,
four
subcategories
to
SIC
code
3331,
one
subcategory
to
SIC
code
3334,
13
subcategories
to
SIC
code
3339,
and
12
subcategories
to
SIC
code
3341.

1
ERG
assigned
the
Metallurgical
Acid
Plants
Subcategory
to
SIC
Code
3331.
According
to
Dan
Edelstein
of
the
U.
S.
G.
S.
Minerals
Division,
metallurgical
acid
recovery
is
done
mostly
for
primary
smelting.
Also,
according
to
the
Technical
Development
Document
for
the
nonferrous
metals
manufacturing
effluent
limitations
guidelines
and
standards,
it
is
more
often
associated
with
copper,
zinc,
lead,
and
molybdenum.

2
ERG
assigned
the
Primary
and
Secondary
Germanium
and
Gallium
Subcategory
to
SIC
Code
3339,
because
ERG
was
unable
to
separate
the
secondary
facility
pollutant
loads
from
the
primary
facility
pollutant
loads.

3
ERG
assigned
the
Primary
and
Secondary
Titanium
Subcategory
to
SIC
Code
3339
because
ERG
was
unable
to
separate
the
secondary
facility
pollutant
loads
from
the
primary
facility
pollutant
loads.
