SUBJECT:
Review
of
the
TWPE
Loads
for
Selected
Nonferrous
Metals
Manufacturing
Facilities
Calculated
Using
2000
PCS
Data
This
memorandum
presents
the
results
of
a
review
of
the
Toxic
Weighted
Pound
Equivalents
(
TWPE)
loads
for
selected
nonferrous
metals
(
NFM)
manufacturing
facilities
calculated
using
2000
Permit
Compliance
System
(
PCS)
data.
It
provides
background
information
on
the
NFM
manufacturing
facilities
that
discharged
90
percent
of
the
TWPE
load,
discusses
the
pollutants
with
the
highest
TWPE
loads,
and
identifies
the
NFM
manufacturing
facilities
that
discharged
the
pollutants
with
the
highest
TWPE
loads.
The
PCSLoads2000
database
only
contains
pollutant
loads
for
direct
discharging
facilities
that
are
major
dischargers.
The
development
of
this
database
is
discussed
in
more
detail
in
the
report
entitled
Development
of
PCSLoads2000,
dated
December
12,
2003.
The
data
dictionary
for
the
PCSLoads2000
database
is
entitled
PCSLoads2000
Data
Dictionary,
dated
December
12,
2003.
Pollutant
loads
discharged
by
indirect
dischargers
are
available
in
the
2000
Toxics
Release
Inventory
(
TRI)
database.

Background
Twenty
of
the
NFM
manufacturing
facilities
in
the
2000
PCS
database
discharged
90
percent
of
the
total
TWPE
load
for
the
NFM
manufacturing
industry.
Two
of
the
20
facilities
discharged
35
percent
of
the
total
TWPE
load.
Twelve
facilities
have
a
SIC
code
of
3334,
six
have
a
SIC
code
of
3339,
and
two
have
a
SIC
code
of
3341.
The
total
TWPE
load
discharged
by
the
20
facilities
was
392,884.
Attachment
A
lists
the
TWPE
load
by
facility
and
by
pollutant.
The
percentage
of
the
total
TWPE
load
for
each
pollutant
by
facility
and
the
cumulative
percentage
of
the
total
TWPE
load
for
each
pollutant
by
facility
also
are
presented
in
Attachment
A.

Pollutants
With
High
TWPE
Loads
The
TWPE
load
for
15
pollutants
comprises
90
percent
of
the
total
TWPE
load
for
NFM
manufacturing
facilities
calculated
using
2000
PCS
data.
The
15
pollutants
and
the
TWPE
load
for
each
pollutant
are
listed
in
Table
1.

The
TWPE
load
for
eight
of
the
top
15
pollutants
was
discharged
by
only
one
facility.
Two
facilities
discharged
100
percent
of
the
TWPE
load
for
molybdenum
and
two
facilities
discharged
60
percent
of
the
TWPE
load
for
benzo(
a)
pyrene.
For
the
other
five
pollutants,
one
facility
discharged
most
of
the
TWPE
load
for
each
pollutant.

The
effluent
limitations
guidelines
(
ELG)
for
the
NFM
manufacturing
industry
contain
limits
in
one
or
more
subcategories
for
the
following
10
of
the
top
15
pollutants:
benzo(
a)
pyrene,
cyanide
(
total),
zinc
(
total),
aluminum
(
total),
free
cyanide,
fluoride
(
total),
lead
(
total),
molybdenum
(
total),
arsenic,
and
mercury.
If
EPA
decides
not
to
establish
limits
for
the
other
pollutants
in
an
ELG,
limits
for
those
pollutants
and
revised
limits
for
already
regulated
pollutants
could
be
established
on
a
case­
by­
case
basis
in
a
National
Pollutant
Discharge
Elimination
System
permit
based
on
Best
Professional
Judgement.
This
is
a
feasible
approach
because
most
of
the
TWPE
load
for
each
of
the
top
15
pollutants
is
from
one
or
two
NFM
manufacturing
facilities.
