MEMORANDUM
TO:
National
Strategy
Project
File
FROM:
Patrick
Goodwin,
ERG
DATE:
June
16,
2003
SUBJECT:
List
of
MP&
M
Chemicals
for
Use
in
MP&
M/
Metal
Finishing
Breakout
Of
the
400
SIC
codes
that
have
water
discharges
represented
in
the
RSEI
model,
144
are
classified
as
belonging
to
both
the
Metal
Products
and
Machinery
(
MP&
M)
and
Metal
Finishing
point
source
categories.
Throughout
the
RSEI
analysis,
hazards
and
other
ranking
values
for
a
particular
facility's
discharges
were
counted
towards
all
point
source
categories
that
apply
to
that
facility's
SIC
code.
Therefore,
all
discharges
from
these
144
"
MP&
M/
MF"
SIC
codes
were
being
double
counted,
with
their
ranking
values
contributing
to
the
totals
for
both
MP&
M
and
Metal
Finishing.
Due
to
the
extent
of
this
double­
counting,
EPA
decided
that
discharges
from
facilities
in
these
144
SIC
codes
should
be
split
into
MP&
M
and
Metal
Finishing
components.

The
MP&
M
rule
as
promulgated
regulates
oil
and
grease
(
O&
G)
and
total
suspended
solids
(
TSS)
in
direct
discharges
from
certain
facilities
that
generate
oily
wastewater;
it
does
not
specifically
regulate
any
TRI
chemicals.
Therefore,
in
order
to
determine
which
discharges
represented
in
RSEI
would
be
split
into
MP&
M,
it
was
necessary
to
create
a
list
of
TRI
chemicals
whose
discharges
would
be
indirectly
controlled
by
the
MP&
M
rule
(
i.
e.,
chemicals
that
would
be
removed
from
wastewater
due
to
treatment
for
O&
G
and
TSS).
Once
this
list
was
determined,
direct
discharges
of
these
chemicals
from
facilities
in
the
144
MP&
M/
MF
SIC
codes
would
be
considered
MP&
M
discharges;
all
others
would
be
considered
Metal
Finishing
discharges.

A
list
of
"
MP&
M
Organics
and
Conventionals"
was
obtained
from
Jenn
Hamilton.
This
table
lists
the
88
organic
"
pollutants
of
concern"
for
the
MP&
M
rule,
and
is
included
as
Table
1.
This
was
used
to
update
a
table
listing
the
612
TRI
chemicals
to
indicate
which
chemicals
were
expected
to
be
controlled
under
MP&
M.
This
update
was
performed
based
on
CAS
Number,
and
identified
45
chemicals.

The
remaining
43
MP&
M
chemicals
that
did
not
have
a
TRI
match
(
based
on
CAS
Number)
were
then
examined
to
see
if
they
fell
within
a
TRI
compound
category
or
otherwise
should
be
considered
representative
of
a
TRI
chemical.
If
the
list
of
MP&
M
chemicals
was
found
to
include
a
chemical
that
fell
within
a
TRI
compound
category,
the
entire
category
would
then
be
considered
MP&
M
for
the
purposes
of
the
RSEI
analysis.
The
following
is
a
list
of
organic
TRI
compound
categories
that
were
evaluated:
CAS
Number
TRI
Compound
Category
2
N084
Chlorophenols
N120
Diisocyanates
N150
Dioxin
and
dioxin­
like
compounds
N171
Ethylenebisdithiocarbamic
acid,
salts
and
esters
N230
Certain
glycol
ethers
N575
Polybrominated
biphenyls
(
PBBs)
N583
Polychlorinated
alkanes
N590
Polycyclic
aromatic
compounds
(
PACs)

Three
TRI
compound
categories
(
diisocyanates,
dioxins,
and
PACs)
include
specifically
listed
chemicals.
These
chemicals
were
evaluated
to
see
if
any
were
included
in
the
list
of
MP&
M
pollutants
of
concern.
One
MP&
M
pollutant
of
concern,
fluoranthene
(
CAS
No.
206­
44­
0),
is
listed
as
a
PAC.
No
other
matches
were
found
in
these
compound
categories.

Two
TRI
compound
categories
(
ethylenebisdithiocarbamic
acid
and
PBBs)
did
not
have
any
reported
discharges
in
RSEI.
These
compound
categories
were
not
evaluated.

Using
best
professional
judgement,
ERG
determined
that
none
of
the
unmatched
MP&
M
chemicals
fell
within
any
of
the
other
three
TRI
compound
categories
(
chlorophenols,
glycol
ethers,
polychlorinated
alkanes).
This
decision
was
aided
by
TRI
guidance
that
provided
an
extensive,
but
not
exhaustive,
list
of
chemicals
in
the
chlorophenols
category.

This
analysis
resulted
in
the
addition
of
the
following
three
TRI
chemicals
to
the
list
of
MP&
M
chemicals,
bringing
the
total
to
48:

CAS
Number
Chemical
Name
N590
Polycyclic
aromatic
compounds
(
based
on
the
listing
of
fluoranthene
as
an
MP&
M­
controlled
chemical)
106423
p­
Xylene
(
based
on
the
listing
of
o+
p
xylene
as
an
MP&

controlled
chemical)
1330207
Xylene,
mixed
isomers
(
based
on
the
listing
of
several
xylene
isomers
as
MP&
M­
controlled
chemicals)

The
list
of
48
chemicals
that
were
broken
out
to
MP&
M
(
for
those
SIC
codes
in
both
MP&
M
and
Metal
Finishing
point
source
categories)
is
provided
in
Table
2.
Direct
discharges
of
these
chemicals
from
facilities
within
any
of
the
144
MP&
M/
MF
SIC
codes
were
considered
to
be
MP&
M
discharges,
and
their
ranking
values
were
assigned
accordingly.
All
indirect
discharges
from
these
facilities,
as
well
as
direct
discharges
of
chemicals
not
identified
as
being
controlled
by
MP&
M,
were
considered
to
be
Metal
Finishing
discharges,
and
their
ranking
values
were
assigned
accordingly.
