II.
Background
A.
What
Action
is
the
Agency
Taking?
This
ANPRM
is
alerting
stakeholders
that
EPA
is
considering
changing
procedures
and
requirements
for
naming
enzymes
and
proteins
for
the
purpose
of
listing
those
substances
on
the
TSCA
Inventory.
Specifically,
EPA
has
identified
four
elements
that
it
currently
believes
are
appropriate
for
use
in
creating
unique
and
unambiguous
identities
for
proteinaceous
enzymes
on
the
TSCA
Inventory.
Through
this
ANPRM,
EPA
is
also
soliciting
public
comment
on
the
scientific
appropriateness
and
technical
feasibility
of
using
the
identification
elements
summarized
herein.

B.
What
is
the
Agency's
Authority
for
Taking
this
Action?
Section
8(
b)
of
TSCA
requires
EPA
to
``
compile,
keep
current,
and
publish
a
list
of
each
chemical
substance
which
is
manufactured
or
processed
in
the
United
States''
(
the
TSCA
Inventory).
In
order
to
fulfill
this
requirement,
EPA
must
continuously
update
and
keep
current
various
types
of
information,
including,
but
not
limited
to,
the
information
used
to
identify
any
new
chemical
substance
that
is
reported
to
be
manufactured
or
processed
in
the
United
States.
EPA
also
makes
corrections,
when
necessary,
of
previously
reported
information
on
the
TSCA
Inventory.

C.
TSCA
Inventory
Background
As
stated
above,
TSCA
section
8(
b)
requires
EPA
to
compile,
keep
current,
and
publish
a
list
of
chemical
substances
which
are
manufactured
(
including
imported)
or
processed
in
the
United
States.
This
listing,
known
as
the
``
TSCA
Inventory,''
informs
the
public
of
which
chemical
substances
are
being
manufactured,
imported,
or
processed
in
the
United
States
for
commercial
purposes.
For
the
TSCA
Inventory
to
accurately
inform
the
public,
it
must
be
continuously
and
accurately
updated
as
new
information
becomes
available.
The
updating
process
includes
adding
to
the
Inventory
the
identities
of
new
chemical
substances
that
are
being
introduced
into
U.
S.
commerce
and
corrections
when
necessary
of
the
identities
of
previously
reported
substances.
The
Agency
has
developed
policies
regarding
the
identification
of
chemical
substances
for
the
purpose
of
assigning
a
unique
description
of
each
substance
on
the
TSCA
Inventory.
Published
nomenclature
guidance
is
currently
available
for
polymeric
substances,
substances
containing
varying
carbon
chain
lengths,
complex
reaction
products,
mixtures,
and
chemical
substances
of
unknown
or
variable
compositions.
Approximately
81,500
chemical
substances,
as
defined
in
section
3
of
TSCA,
are
on
the
TSCA
Inventory
at
this
time.
In
its
implementation
of
TSCA,
EPA
defines
chemical
substances
as
either
``
existing''
chemicals
or
``
new''
chemicals.
The
only
way
to
determine
if
a
substance
is
new
or
existing
is
by
consulting
the
TSCA
Inventory.
Any
substance
that
is
listed
on
the
TSCA
Inventory
is
an
existing
chemical,
otherwise
it
is
a
new
chemical.
If
a
substance
is
a
new
chemical,
generally
it
can
be
manufactured
or
imported
for
nonexempt
commercial
purposes
only
when
a
Premanufacture
Notice
(
PMN)
is
submitted
at
least
90
days
before
the
manufacture
or
import
of
such
substance
begins
(
see
section
5(
a)
of
TSCA
and
40
CFR
part
720).
During
this
90­
day
review
period
EPA
will
evaluate
the
proposed
manufacture,
processing,
use,
distribution
in
commerce,
and
disposal
of
the
substance,
and
if
necessary,
prohibit
or
limit
any
activity
that
may
result
in
an
unreasonable
risk
of
injury
to
human
health
or

environment.
A
new
chemical
substance
also
can
be
manufactured
or
imported
if
it
is
subject
to
an
exemption
from
full
premanufacture
reporting,
for
example
a
Low
Volume
Exemption
or
a
Test
Marketing
Exemption
(
see
40
CFR
part
723
and
40
CFR
720.38).
In
addition
a
new
chemical
substance
is
excluded
from
premanufacture
reporting
under
certain
conditions
such
as
manufacture
or
import
of
small
quantities
for
research
and
development
or
if
the
substance
does
not
meet
the
TSCA
definition
of
chemical
substance
as
defined
in
40
CFR
part
720.3(
e)
(
see
40
CFR
720.30).

D.
Inventory
Listings
of
Enzymes
When
EPA
promulgated
the
TSCA
Inventory
Reporting
Regulations
of
1977
(
42
FR
64572,
December
23,
1977),
the
Agency
did
not
provide
specific
guidance
regarding
how
complex
biological
compounds
should
be
identified.
However,
EPA
did
publish
the
TSCA
Candidates
List
to
provide
examples
of
the
types
of
substances
that
would
be
reportable
for
the
Inventory.
That
list
included
enzymes.
As
a
result,
approximately
150
enzymes
were
reported
and
listed
on
the
TSCA
Inventory
without
specific
agency
guidance
regarding
how
they
should
be
unambiguously
identified.
The
original
Inventory
listings
for
nonenzymatic
proteins
and
other
complex
biological
compounds
are
based
on
information
originally
reported
to
EPA
that
varies
widely
in
the
type
and
specificity
of
information
included.
The
enzymes
currently
on
the
TSCA
Inventory
are
identified
by
a
Chemical
Abstract
Services
(
CAS)
Registry
Number
and
Chemical
Abstracts
9th
Collective
Index
Name.
The
names
assigned
to
these
enzymes
by
EPA
vary
in
the
type
and
specificity
of
information
included
due
to
wide
variation
in
the
type
and
amount
of
information
originally
reported
to
EPA.
For
some
enzymes,
the
name
is
broad,
defining
only
the
most
generic
catalytic
activity
of
the
enzyme
(
e.
g.,
proteinase).
As
a
result
of
the
existing
broad
and
generic
TSCA
Inventory
enzyme
listings,
it
has
been
difficult
for
EPA
to
determine
whether
enzyme
substances
are
new
and
distinct,
or
covered
under
existing
listings.
In
most
cases,
newly
developed
enzymes
appear
to
be
subsumed
under
one
of
the
current
broad
and
generic
TSCA
Inventory
enzyme
listings,
which
means
that,
although
they
are
newly
developed,
they
appear
to
be
existing
chemicals.
This,
in
turn,
means
that
EPA
is
reviewing
very
few
new
enzymes
under
section
5
of
TSCA,
despite
the
ongoing
innovation
in
this
field
as
to
the
specificity
and
functions
of
commercially
available
enzymes.
Under
the
existing
nomenclature
system,
therefore,
EPA
may
not
be
addressing
all
of
the
newly
developed
enzymes
and
considering
the
potential
risks
that
may
be
associated
with
these
substances
under
section
5
of
TSCA.

specific
nomenclature
system
would
allow
EPA
to
assess
newly
developed
enzymes
and
take
actions
needed
to
prevent
potential
unreasonable
risks
to
health
and
the
environment
that
may
be
associated
with
these
substances
under
section
5
of
TSCA
before
they
occur.
In
addition,
the
broad
TSCA
Inventory
enzyme
listings,
the
lack
of
clear
reporting
guidelines,
and
the
absence
of
policy
concerning
what
structural
variation
or
changes
trigger
reporting,
also
make
it
difficult
for
manufacturers
to
determine
whether
enzyme
substances
are
new
or
covered
under
existing
listings.
Recognizing
that
enzyme
listings
on
the
Inventory
were
broad,
EPA
developed
an
interim
policy
that
manufacturers
of
enzymes
should
contact
EPA
regarding
submission
of
a
bona
fide
intent
to
manufacture
before
producing
any
enzyme.
EPA
also
routinely
advised
submitters
of
a
Notice
of
Bona
Fide
Intent
to
Manufacture
that
the
Agency
may
modify
the
method
of
listing
enzymes
on
the
Inventory
and
that
this
could
require
reporting
at
a
higher
level
of
detail
than
is
required
at
present.
This
case­
by­
case
determination
creates
uncertainty
and
an
unnecessary
burden
for
both
the
Agency
and
PMN
submitters.
More
specific
guidelines
for
identifying
enzymes
on
the
TSCA
Inventory
would
make
the
process
of
deciding
whether
an
enzyme
is
new
or
existing
more
predictable
and
transparent.
In
order
to
more
effectively
meet
its
statutory
obligation
under
TSCA
to
prevent
unreasonable
risk
to
human
health
and
the
environment
and
to
maintain
a
complete
and
accurate
list
of
all
chemical
substances
manufactured,
imported,
or
processed,
EPA
believes
it
is
necessary
to
refine
its
policies
with
regard
to
enzyme
identification
reporting
requirements.
The
timely
development
of
identification
reporting
guidelines
for
enzymes
is
essential,
given
the
increasing
use
of
enzymes
in
commerce,
the
wide
variety
of
enzymes
that
are
being
produced,
and
the
development
of
new
and
different
manufacturing
techniques.

III.
Identification
Elements
A.
Description
of
Identification
Elements
EPA
has
identified
four
elements
that
it
currently
believes
are
appropriate
to
use
in
combination
to
create
unambiguous
listings
for
proteinaceous
enzymes
on
the
TSCA
Inventory:
1.
Function.
2.
Source.
3.
Processing.
4.
Amino
acid
sequence.
EPA
believes
that
no
individual
element
provides
sufficient
identification
information
by
itself.
Rather,
EPA
anticipates
that
all
four
elements
will
provide
useful
and
necessary
information
for
the
***
EO
12866
Review
Draft
of

unambiguous
identification
of
proteinaceous
enzymes
and
that
some
combination
of
these
and/
or
additional
identification
elements
may
be
appropriate
for
other
enzymes
and
proteins.
The
function
of
an
enzyme
refers
to
its
catalytic
activity.
The
internationally
accepted
nomenclature
conventions
of
the
Nomenclature
Committee
of
the
International
Union
of
Biochemistry
and
Molecular
Biology
(
NC­
IUBMB)
describe
and
differentiate
enzymes
based
on
catalytic
activity.
Function,
or
catalytic
activity,
could
be
incorporated
as
an
element
of
chemical
identity
of
an
enzyme
on
the
TSCA
Inventory
using
this
standard
enzyme
nomenclature.
Source
refers
to:
The
organism
from
which
the
gene
encoding
the
enzyme
was
derived
and
the
organism
or
manufacturing
platform
(
e.
g.,
tissue
culture)
in
which
the
enzyme
is
produced.
The
two
sources
may
be
the
same
or
differ
when
the
enzyme
gene
from
one
organism
is
introduced
through
genetic
engineering
into
a
different
organism
or
through
the
use
of
a
synthetic
sequence.
Processing
refers
to
procedures
used
to
isolate
the
enzyme
from
the
production
organism
or
manufacturing
platform,
procedures
used
to
purify
it,
or
any
chemical
reactions
to
which
the
enzyme
is
subjected
to
produce
the
final
product.
The
amino
acid
sequence
of
an
enzyme
or
protein
is
known
as
its
primary
structure.
The
amino
acid
sequence
is
a
systematic
representation
of
the
linear
chain
of
amino
acids
connected
via
amide
bonds
that
produce
a
polypeptide.
An
example
of
enzyme
nomenclature
using
these
identification
elements
would
be
neopullulanase
(
Enzyme
Commission
3.2.1.135),
produced
by
Bacillus
stearothermophilus,
treated
with
acetic
acid,
with
amino
acid
sequence:

This
is
one
version
of
enzyme
nomenclature
using
these
four
identification
elements.
Actual
nomenclature
would
vary
widely
depending
on
use
of
all
four
elements,
nomenclature
used
for
each
element,
and
the
level
of
detail
ultimately
used
for
each
element.

B.
Issues
for
Public
Comment
EPA
is
soliciting
comments
on
all
aspects
of
the
discussion
presented
in
this
document
regarding
nomenclature
issues
for
enzymes
and
proteins,
for
purposes
of
listing
these
chemical
substances
on
the
TSCA
Inventory.
EPA
is
particularly
interested
in
receiving
comments
on
the
following
topics.
EPA
has
identified
four
elements
(
listed
in
Unit
III.
A.),
that
it
currently
believes
are
appropriate
to
derive
unique
nomenclature
for
the
purpose
of
unambiguously
listing
proteinaceous
enzymes
on
the
TSCA
Inventory.
EPA
is
seeking
comments
on
the
scientific
appropriateness
of
using
these
identification
elements,
the
level
of
detail
necessary
to
create
specific,
unambiguous
TSCA
Inventory
listings,
the
technical
feasibility
of
providing
such
information,
and
any
additional
or
alternative
elements
that
could
be
used
to
identify
proteinaceous
enzymes
on
the
TSCA
Inventory.
Are
the
identification
elements
proposed
for
proteinaceous
enzymes
scientifically
appropriate
and
sufficiently
comprehensive
for
non­
proteinaceous
enzymes
and
non­
enzymatic
proteins?
Are
there
additional
or
alternative
identification
elements
that
should
be
used
in
creating
TSCA
Inventory
listings
for
non­
proteinaceous
enzymes
and
non­
enzymatic
proteins?
If
so,
what
are
these
alternatives,
and
why
is
it
believed
that
these
alternatives
are
preferable.

IV.
Do
Any
Statutory
or
Executive
Order
Reviews
Apply
to
this
Action?
Under
Executive
Order
12866,
entitled
Regulatory
Planning
and
Review
(
58
FR
51735,
October
4,
1993),
it
has
been
determined
that
this
ANPRM
is
a
``
significant
regulatory
action''
under
section
3(
f)
of
the
Executive
order.
The
Agency
therefore
submitted
this
document
to
OMB
for
the
10­
day
review
period
afforded
under
this
Executive
order.
Any
changes
made
in
response
to
OMB
comments
during
that
review
have
been
documented
in
the
docket
as
required
by
the
Executive
order.
Since
this
ANPRM
does
not
impose
or
propose
any
requirements,
and
instead
seeks
comments
and
suggestions
for
the
Agency
to
consider
in
developing
a
subsequent
notice
of
proposed
rulemaking,

action.
As
part
of
your
comments
on
this
ANPRM
you
may
include
any
comments
or
information
that
you
have
regarding
these
requirements.
In
particular,
any
comments
or
information
that
would
help
the
Agency
to
assess
the
potential
impact
of
a
rule
on
small
entities
pursuant
to
the
Regulatory
Flexibility
Act
(
RFA)
(
5
U.
S.
C.
601
et
seq.);
to
consider
voluntary
consensus
standards
pursuant
to
section
12(
d)
of
the
National
Technology
Transfer
and
Advancement
Act
of
1995
(

1997).
The
Agency
will
consider
such
comments
during
the
development
of
any
subsequent
notice
of
proposed
rulemaking
as
it
takes
appropriate
steps
to
address
any
applicable
requirements.
