Federal Register / Vol. 78, No. 27 / Friday, February 8, 2013 / Rules and Regulations
wreier-aviles on DSK7SPTVN1PROD with RULES
the CAA. Accordingly, this action
merely approves state law as meeting
Federal requirements and does not
impose additional requirements beyond
those imposed by state law. For that
reason, this action:
• Is not a ‘‘significant regulatory
action’’ subject to review by the Office
of Management and Budget under
Executive Order 12866 (58 FR 51735,
October 4, 1993);
• does not impose an information
collection burden under the provisions
of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.);
• is certified as not having a
significant economic impact on a
substantial number of small entities
under the Regulatory Flexibility Act (5
U.S.C. 601 et seq.);
• does not contain any unfunded
mandate or significantly or uniquely
affect small governments, as described
in the Unfunded Mandates Reform Act
of 1995 (Pub. L. 104–4);
• does not have Federalism
implications as specified in Executive
Order 13132 (64 FR 43255, August 10,
1999);
• is not an economically significant
regulatory action based on health or
safety risks subject to Executive Order
13045 (62 FR 19885, April 23, 1997);
• is not a significant regulatory action
subject to Executive Order 13211 (66 FR
28355, May 22, 2001);
• is not subject to requirements of
Section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) because
application of those requirements would
be inconsistent with the CAA; and
• does not provide EPA with the
discretionary authority to address, as
appropriate, disproportionate human
health or environmental effects, using
practicable and legally permissible
methods, under Executive Order 12898
(59 FR 7629, February 16, 1994).
In addition, this rule does not have
tribal implications as specified by
Executive Order 13175 (65 FR 67249,
November 9, 2000), because the SIP is
not approved to apply in Indian country
located in the state, and EPA notes that
it will not impose substantial direct
costs on tribal governments or preempt
tribal law.
B. Submission to Congress and the
Comptroller General
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, to each House of the
VerDate Mar<15>2010

Congress and to the Comptroller General
of the United States. Section 804,
however, exempts from section 801 the
following types of rules: rules of
particular applicability; rules relating to
agency management or personnel; and
rules of agency organization, procedure,
or practice that do not substantially
affect the rights or obligations of nonagency parties. 5 U.S.C. 804(3). Because
this is a rule of particular applicability,
EPA is not required to submit a rule
report regarding this action under
section 801.
C. Petitions for Judicial Review
Under section 307(b)(1) of the CAA,
petitions for judicial review of this
action must be filed in the United States
Court of Appeals for the appropriate
circuit by April 9, 2013. Filing a petition
for reconsideration by the Administrator
of this final rule does not affect the
finality of this action for the purposes of
judicial review nor does it extend the
time within which a petition for judicial
review may be filed, and shall not
postpone the effectiveness of such rule
or action. Parties with objections to this
direct final rule are encouraged to file a
comment in response to the parallel
notice of proposed rulemaking for this
action published in the proposed rules
section of today’s Federal Register,
rather than file an immediate petition
for judicial review of this direct final
rule, so that EPA can withdraw this
direct final rule and address the
comment in the proposed rulemaking.

II. Background and Statutory Findings
In the Federal Register of November
7, 2012 (77 FR 66781) (FRL–9367–5),
EPA issued a document pursuant to
FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide tolerance petition (PP 2E8059)
by Pioneer Hi-Bred International, Inc.
(DuPont Pioneer), 7100 NW., 62nd
Avenue, P.O. Box 1000, Johnston, Iowa,
50131. The petition requested that 40
CFR part 174 be amended by
establishing an exemption from the
requirement of a tolerance for residues
of Glycine max herbicide-resistant
acetolactate synthase (GM–HRA) when
used as a plant-incorporated protectant
(PIP) inert ingredient in or on the food
and feed commodities of soybean. That
document referenced a summary of the
petition prepared by the petitioner,
Pioneer Hi-Bred International, Inc.
(DuPont Pioneer), which is available in
the docket, https://www.regulations.gov.
There were no comments received in
response to the notice of filing.
Section 408(c)(2)(A)(i) of FFDCA
allows EPA to establish an exemption
from the requirement for a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the exemption is ‘‘safe.’’
Section 408(c)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Pursuant to
FFDCA section 408(c)(2)(B), in
establishing or maintaining in effect an
exemption from the requirement of a
tolerance, EPA must take into account
the factors set forth in FFDCA section
408(b)(2)(C), which require EPA to give
special consideration to exposure of
infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue * * *. ’’ Additionally,
FFDCA section 408(b)(2)(D) requires
that the Agency consider ‘‘available
information concerning the cumulative
effects of a particular pesticide’s
residues’’ and ‘‘other substances that
have a common mechanism of toxicity.’’
EPA performs a number of analyses to
determine the risks from aggregate
exposure to pesticide residues. First,
EPA determines the toxicity of
pesticides. Second, EPA examines
exposure to the pesticide through food,
drinking water, and through other
exposures that occur as a result of
pesticide use in residential settings.
III. Toxicological Profile
Consistent with FFDCA section
408(b)(2)(D), EPA has reviewed the
available scientific data and other
relevant information in support of this
action and considered its validity,
completeness and reliability, and the
relationship of this information to
human risk. EPA has also considered
available information concerning the
variability of the sensitivities of major
identifiable subgroups of consumers,
including infants and children.
A. Product Characterization Overview
Acetolactate synthase (ALS) protein,
also known as acetohydroxyacid
synthase (AHAS), is a key enzyme that
catalyzes the first common step in the
biosynthesis of the essential branchedchain amino acids, and is obligatory for
plant development. The gene that
encodes the GM–HRA protein, gm-hra,
is derived from the gm-als I gene, a
naturally occurring soybean gene that
encodes for acetolactate synthase I (GM–
ALS I) protein. Changes were made in
the DNA gene sequence for gm-als I to
produce gm-hra. The modified gene was
then introduced into the plant’s genome
through particle bombardment (with the
PHP30987A fragment). The GM–HRA
E:\FR\FM\08FER1.SGM
08FER1
Federal Register / Vol. 78, No. 27 / Friday, February 8, 2013 / Rules and Regulations
protein is 604 amino acids in length,
with a predicted molecular weight of 65
kilodaltons (kDa), and is >99%
homologous with the native GM–ALS I
protein produced in soybeans. This
minor modification of the endogenous
GM–ALS I protein to GM–HRA protein
yields an enzyme that is resistant to
ALS-inhibiting herbicides. Thus, the
GM–HRA protein will be useful as a
selectable marker in soybean
transformation events. As part of a
genetic construct introduced into a
plant’s genome, GM–HRA itself does not
have insecticidal activity and is
therefore functionally inert as part of a
PIP. Potentially, GM–HRA also might
serve as an herbicide-tolerant trait in
soybeans, a use over which the U.S.
Department of Agriculture (USDA) has
separate regulatory jurisdiction.
wreier-aviles on DSK7SPTVN1PROD with RULES
B. Mammalian Toxicity Assessment
DuPont Pioneer, has submitted acute
oral toxicity data demonstrating the lack
of mammalian toxicity at relatively high
levels of exposure to the pure GM–HRA
protein. These data demonstrate the
safety of the product at a level well
above maximum possible exposure
levels that are reasonably anticipated in
the crop (Ref. 1).
An acute oral toxicity study in mice
indicated that GM–HRA is nontoxic
(Ref. 2). Two groups of five males and
five females mice were orally dosed (via
gavage) with 2,000 milligrams/kilograms
body weight (mg/kg bwt) of the test
substance, a biochemically and
functionally equivalent, microbially
produced GM–HRA protein. There were
no adverse clinical signs or findings at
necropsy in the test animals.
When proteins are toxic, they are
known to act via acute mechanisms and
at very low dose levels (Ref. 3). Since no
acute oral effects were shown to be
caused by GM–HRA, even at relatively
high dose levels (up to 2,000 mg/kg
bwt), the GM–HRA protein is not
considered to be toxic. In support of this
conclusion, amino acid sequence
comparisons between the GM–HRA
protein and known toxic proteins in
protein databases found no similarities
that would contradict the results of the
acute oral study.
C. Allergenicity Assessment
Since GM–HRA is a protein,
allergenic sensitivities were considered.
Currently, no definitive tests exist for
determining the allergenic potential of
novel proteins. Current scientific
knowledge suggests that common food
allergens tend to be resistant to
degradation by acid and proteases; they
also may be glycosylated, and are
present at high concentrations in food.
VerDate Mar<15>2010
14:10 Feb 07, 2013
Jkt 229001
Using a ‘‘weight-of-evidence’’ approach,
EPA considered the source of the trait,
amino acid sequence similarity with
known allergens, its prevalence in food,
and biochemical properties of the
protein, including in vitro digestibility
in simulated gastric fluid (SGF), and
glycosylation (Ref. 4). The results of the
EPA’s analysis are as follows:
1. Source of the trait. The donor
organism is Glycine max (soybean),
which has an endogenous gene (gm-als
I) that encodes for acetolactate synthase
I (GM–ALS I) protein. Although soybean
is one of the major food allergens, none
of the known soy allergens is a member
of the ALS protein family, including
ALS protein. ALS enzymes are widely
distributed in nature, and als genes have
been isolated from bacteria, fungi, algae
and plants (Refs. 5, 6, 7, and 8). Amino
acid sequencing (BLASTP analysis)
yielded 12,451 structurally or
functionally related protein accessions
(Ref. 9).The gm-hra gene, coding for the
proposed PIP inert ingredient GM–HRA
protein, was produced by transforming
the naturally occurring, herbicidesensitive gm-als I genetic sequence. The
new gene was introduced into the plant,
and the resulting herbicide-tolerant
GM–HRA protein differs from the ALS
I protein by only two amino acids. Both
of the two amino acid substitutions in
GM–HRA are already present in
commercially available crop varieties
(soybean, sunflower, maize, and canola
(Refs. 10, 11, 12 and 13)) that are
naturally tolerant to ALS-inhibiting
herbicides.
2. Amino acid sequence. A
comparison of the amino acid sequence
of GM–HRA with known allergens
found no significant overall sequence
similarity or identity at the level of eight
contiguous amino acid residues, the
level of sensitivity needed to detect
potential allergens.
3. Prevalence in food. ALS enzymes
have been part of the human diet by
virtue of their presence in soybeans and
other commercial food crops (soybean,
maize, wheat, rice, and canola). Some of
these enzymes contain natural
mutations that include the same two
amino acid substitutions as GM–HRA
protein that render them tolerant to
ALS-inhibiting herbicides (Ref. 12), and
no ALS-related food allergies have been
reported.
4. Digestibility. The GM–HRA protein
was rapidly digested (in less than 30
seconds) in simulated mammalian
gastric fluid (which has a highly acidic
pH of 1.2 and includes the protein
digesting enzyme, pepsin, found in
gastric fluid) after incubation at 37 °C.
5. Glycosylation. The GM–HRA
protein expressed in soybean is not
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
9319
glycosylated. Considering all of the
available information, EPA has
concluded that the potential for GM–
HRA to be a food allergen is minimal.
IV. Aggregate Exposures
In examining aggregate exposure,
FFDCA section 408 directs EPA to
consider available information
concerning exposures from the pesticide
residue in food and all other nonoccupational exposures, including
drinking water from ground water or
surface water and exposure through
pesticide use in gardens, lawns, or
buildings (residential and other indoor
uses).
The Agency has considered available
information on the aggregate exposure
levels of consumers and major
identifiable subgroups of consumers,
including infants and children, to the
proposed pesticide PIP inert residue,
GM–HRA protein, and to other related
substances. This protein is an enzyme
produced in soybean by a gene that was
genetically derived from a naturally
occurring soybean gene that encodes an
herbicide-sensitive ALS enzyme. The
altered gene is reinserted into soybean,
and the resulting GM–HRA protein has
greater than 99% similarity with the
natural herbicide-sensitive protein
enzyme, differing only in two amino
acids (Ref. 13). These minor changes
confer resistance of the enzyme to
herbicidal pesticides that inhibit ALS
enzymes, which is what allows the GM–
HRA protein to be used as a selectable
herbicide-tolerant marker in soybean
transformation events. The two amino
acid substitutions found in the
engineered GM–HRA protein also occur
as natural mutations in other
commercially available, non-genetically
modified crop varieties that are tolerant
to ALS-inhibiting herbicides, and thus
human exposure to the naturally
occurring protein, in addition to the
proposed PIP inert, is anticipated. The
only route of human exposure that is
likely, however, is through the human
diet, since the proposed PIP inert
ingredient (and the related naturally
occurring ALS enzymes) is contained
within plant cells, which reduces
potential human exposure via other
routes to negligible. Exposure via
residential or lawn use is not expected
because the intended use sites are all
agricultural. Though highly unlikely,
should residues of GM–HRA appear in
drinking water as a result of its use as
a PIP inert ingredient in soybean, the
risk to humans would be very unlikely,
based on the protein’s lack of
mammalian toxicity demonstrated in
the acute oral toxicity study and the
lack of amino acid similarity with
E:\FR\FM\08FER1.SGM

wreier-aviles on DSK7SPTVN1PROD with RULES
V. Cumulative Effects From Substances
With a Common Mechanism of Toxicity
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
Based on the results of acute toxicity
testing, EPA concluded that the
proposed PIP inert, GM–HRA, is not
toxic. EPA also concluded that no toxic
or allergenic metabolites are produced
in soybean or other edible crops from
the activity of this catabolic enzyme. In
addition, GM–HRA as encoded by the
gm-hra gene was previously evaluated
for its safety by the U.S. Food and Drug
Administration (FDA) in two other
transgenic soybean events. In one event,
the gene was modified to produce high
oleic soybean oil (OECD Unique ID No.
DP–3;5423–1), and the other provided
glyphosate and ALS-inhibiting
herbicide tolerance (OECD Unique ID
No. DP–356;43–5) (Refs.14 and 15).
Based upon the information submitted,
FDA concluded that the safety profiles
of these soybean events, the GM–HRA
protein were not materially different
from that of other marketed soybean
varieties, and no safety concerns with
the protein were identified (Refs.16 and
17).
EPA concludes that there are no
cumulative effects associated with GM–
HRA expected from the proposed use as
a PIP inert ingredient in soybean. For
information regarding EPA’s efforts to
determine which chemicals have a
common mechanism of toxicity and to
evaluate the cumulative effects of such
chemicals, see EPA’s Web site at https://
www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S.
Population, Infants and Children
The data submitted and cited
regarding potential health effects for the
GM–HRA protein include the
characterization of the expressed GM–
HRA protein in soybean, as well as the
acute oral toxicity, amino acid sequence
comparisons, and in vitro digestibility
study. The results of these studies were
used to evaluate human risk, and the
validity, completeness, and reliability of
the available data from the studies was
considered.
As discussed in unit III, the acute oral
toxicity data submitted supports the
prediction that the GM–HRA protein
would be nontoxic to humans.
VerDate Mar<15>2010
14:10 Feb 07, 2013
Jkt 229001
Moreover, amino acid sequence analysis
demonstrated that GM–HRA was not
similar to any known protein toxin or
allergen. Other data considered as part
of the allergenicity assessment included:
The structural and functional similarity
of GM–HRA protein with naturally
occurring ALS proteins from soybean
and other food crops; the ALS proteins
are not associated with food
allergenicity; the protein rapidly
degraded in the highly acidic
digestibility study; and GM–HRA
protein not glycosylated when
expressed in the plant. GM–HRA
protein is therefore not expected to be
a human allergen.
Finally, and specifically with regard
to infants and children, FFDCA section
408(b)(2)(C) provides that EPA shall
assess the available information about
consumption patterns among infants
and children, special susceptibility of
infants and children to pesticide
chemical residues, and the cumulative
effects on infants and children of the
residues and other substances with a
common mechanism of toxicity. In
addition, FFDCA section 408(b)(2)(C)
provides that EPA shall apply an
additional tenfold margin of safety for
infants and children in the case of
threshold effects to account for prenatal
and postnatal toxicity and the
completeness of the data base unless
EPA determines that a different margin
of safety will be safe for infants and
children.
Based on its review and consideration
of all the available information, the
Agency concludes that there is a
reasonable certainty that no harm will
result to the U.S. population, including
infants and children, from aggregate
exposure to residues of the GM–HRA
protein and the genetic material
necessary for its production when used
as a PIP inert ingredient in or on food
and feed commodities of soybean. This
includes all anticipated dietary
exposures and all other exposures for
which there is reliable information. The
Agency has also concluded, for the
reasons discussed in more detail above,
that there are no threshold effects of
concern and, as a result, that an
additional margin of safety for infants
and children is unnecessary in this
instance.
VII. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is establishing an exemption
from the requirement of a tolerance
without any numerical limitation.
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
The Codex has not established a MRL
for GM–HRA protein in soybean.
VIII. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
for residues of Glycine max herbicideresistant acetolactate synthase (GM–
HRA) enzyme in or on the food and feed
commodities of soybean when used as
a plant-incorporated protectant inert

X. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This final rule does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA), 44
U.S.C. 3501 et seq., nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of FFDCA section 408(n)(4). As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final

rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA) (15 U.S.C. 272 note).
XI. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule in the Federal
Register. This action is not a ‘‘major

II. Background and Statutory Findings
In the Federal Register of November 7, 2012 (77 FR 66781) (FRL-
9367-5), EPA issued a document pursuant to FFDCA section 408(d)(3), 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition (PP 2E8059) by Pioneer Hi-Bred International, Inc. (DuPont
Pioneer), 7100 NW., 62nd Avenue, P.O. Box 1000, Johnston, Iowa, 50131.
The petition requested that 40 CFR part 174 be amended by establishing
an exemption from the requirement of a tolerance for residues of
Glycine max herbicide-resistant acetolactate synthase (GM-HRA) when
used as a plant-incorporated protectant (PIP) inert ingredient in or on
the food and feed commodities of soybean. That document referenced a
summary of the petition prepared by the petitioner, Pioneer Hi-Bred
International, Inc. (DuPont Pioneer), which is available in the docket,
https://www.regulations.gov. There were no comments received in response
to the notice of filing.
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for a tolerance (the legal limit for a
pesticide chemical residue in or on a food) only if EPA determines that
the exemption is ``safe.'' Section 408(c)(2)(A)(ii) of FFDCA defines
``safe'' to mean that ``there is a reasonable certainty that no harm
will result from aggregate exposure to the pesticide chemical residue,
including all anticipated dietary exposures and all other exposures for
which there is reliable information.'' This includes exposure through
drinking water and in residential settings, but does not include
occupational exposure. Pursuant to FFDCA section 408(c)(2)(B), in
establishing or maintaining in effect an exemption from the requirement
of a tolerance, EPA must take into account the factors set forth in
FFDCA section 408(b)(2)(C), which require EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue * *
*. '' Additionally, FFDCA section 408(b)(2)(D) requires that the Agency
consider ``available information concerning the cumulative effects of a
particular pesticide's residues'' and ``other substances that have a
common mechanism of toxicity.''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. First, EPA determines the
toxicity of pesticides. Second, EPA examines exposure to the pesticide
through food, drinking water, and through other exposures that occur as
a result of pesticide use in residential settings.
III. Toxicological Profile
Consistent with FFDCA section 408(b)(2)(D), EPA has reviewed the
available scientific data and other relevant information in support of
this action and considered its validity, completeness and reliability,
and the relationship of this information to human risk. EPA has also
considered available information concerning the variability of the
sensitivities of major identifiable subgroups of consumers, including
infants and children.
A. Product Characterization Overview
Acetolactate synthase (ALS) protein, also known as acetohydroxyacid
synthase (AHAS), is a key enzyme that catalyzes the first common step
in the biosynthesis of the essential branched-chain amino acids, and is
obligatory for plant development. The gene that encodes the GM-HRA
protein, gm-hra, is derived from the gm-als I gene, a naturally
occurring soybean gene that encodes for acetolactate synthase I (GM-ALS
I) protein. Changes were made in the DNA gene sequence for gm-als I to
produce gm-hra. The modified gene was then introduced into the plant's
genome through particle bombardment (with the PHP30987A fragment). The
GM-HRA
[[Page 9319]]
protein is 604 amino acids in length, with a predicted molecular weight
of 65 kilodaltons (kDa), and is >99% homologous with the native GM-ALS
I protein produced in soybeans. This minor modification of the
endogenous GM-ALS I protein to GM-HRA protein yields an enzyme that is
resistant to ALS-inhibiting herbicides. Thus, the GM-HRA protein will
be useful as a selectable marker in soybean transformation events. As
part of a genetic construct introduced into a plant's genome, GM-HRA
itself does not have insecticidal activity and is therefore
functionally inert as part of a PIP. Potentially, GM-HRA also might
serve as an herbicide-tolerant trait in soybeans, a use over which the
U.S. Department of Agriculture (USDA) has separate regulatory
jurisdiction.
B. Mammalian Toxicity Assessment
DuPont Pioneer, has submitted acute oral toxicity data
demonstrating the lack of mammalian toxicity at relatively high levels
of exposure to the pure GM-HRA protein. These data demonstrate the
safety of the product at a level well above maximum possible exposure
levels that are reasonably anticipated in the crop (Ref. 1).
An acute oral toxicity study in mice indicated that GM-HRA is
nontoxic (Ref. 2). Two groups of five males and five females mice were
orally dosed (via gavage) with 2,000 milligrams/kilograms body weight
(mg/kg bwt) of the test substance, a biochemically and functionally
equivalent, microbially produced GM-HRA protein. There were no adverse
clinical signs or findings at necropsy in the test animals.
When proteins are toxic, they are known to act via acute mechanisms
and at very low dose levels (Ref. 3). Since no acute oral effects were
shown to be caused by GM-HRA, even at relatively high dose levels (up
to 2,000 mg/kg bwt), the GM-HRA protein is not considered to be toxic.
In support of this conclusion, amino acid sequence comparisons between
the GM-HRA protein and known toxic proteins in protein databases found
no similarities that would contradict the results of the acute oral
study.
C. Allergenicity Assessment
Since GM-HRA is a protein, allergenic sensitivities were
considered. Currently, no definitive tests exist for determining the
allergenic potential of novel proteins. Current scientific knowledge
suggests that common food allergens tend to be resistant to degradation
by acid and proteases; they also may be glycosylated, and are present
at high concentrations in food. Using a ``weight-of-evidence''
approach, EPA considered the source of the trait, amino acid sequence
similarity with known allergens, its prevalence in food, and
biochemical properties of the protein, including in vitro digestibility
in simulated gastric fluid (SGF), and glycosylation (Ref. 4). The
results of the EPA's analysis are as follows:
1. Source of the trait. The donor organism is Glycine max
(soybean), which has an endogenous gene (gm-als I) that encodes for
acetolactate synthase I (GM-ALS I) protein. Although soybean is one of
the major food allergens, none of the known soy allergens is a member
of the ALS protein family, including ALS protein. ALS enzymes are
widely distributed in nature, and als genes have been isolated from
bacteria, fungi, algae and plants (Refs. 5, 6, 7, and 8). Amino acid
sequencing (BLASTP analysis) yielded 12,451 structurally or
functionally related protein accessions (Ref. 9).The gm-hra gene,
coding for the proposed PIP inert ingredient GM-HRA protein, was
produced by transforming the naturally occurring, herbicide-sensitive
gm-als I genetic sequence. The new gene was introduced into the plant,
and the resulting herbicide-tolerant GM-HRA protein differs from the
ALS I protein by only two amino acids. Both of the two amino acid
substitutions in GM-HRA are already present in commercially available
crop varieties (soybean, sunflower, maize, and canola (Refs. 10, 11, 12
and 13)) that are naturally tolerant to ALS-inhibiting herbicides.
2. Amino acid sequence. A comparison of the amino acid sequence of
GM-HRA with known allergens found no significant overall sequence
similarity or identity at the level of eight contiguous amino acid
residues, the level of sensitivity needed to detect potential
allergens.
3. Prevalence in food. ALS enzymes have been part of the human diet
by virtue of their presence in soybeans and other commercial food crops
(soybean, maize, wheat, rice, and canola). Some of these enzymes
contain natural mutations that include the same two amino acid
substitutions as GM-HRA protein that render them tolerant to ALS-
inhibiting herbicides (Ref. 12), and no ALS-related food allergies have
been reported.
4. Digestibility. The GM-HRA protein was rapidly digested (in less
than 30 seconds) in simulated mammalian gastric fluid (which has a
highly acidic pH of 1.2 and includes the protein digesting enzyme,
pepsin, found in gastric fluid) after incubation at 37 [deg]C.
5. Glycosylation. The GM-HRA protein expressed in soybean is not
glycosylated. Considering all of the available information, EPA has
concluded that the potential for GM-HRA to be a food allergen is
minimal.
IV. Aggregate Exposures
In examining aggregate exposure, FFDCA section 408 directs EPA to
consider available information concerning exposures from the pesticide
residue in food and all other non-occupational exposures, including
drinking water from ground water or surface water and exposure through
pesticide use in gardens, lawns, or buildings (residential and other
indoor uses).
The Agency has considered available information on the aggregate
exposure levels of consumers and major identifiable subgroups of
consumers, including infants and children, to the proposed pesticide
PIP inert residue, GM-HRA protein, and to other related substances.
This protein is an enzyme produced in soybean by a gene that was
genetically derived from a naturally occurring soybean gene that
encodes an herbicide-sensitive ALS enzyme. The altered gene is
reinserted into soybean, and the resulting GM-HRA protein has greater
than 99% similarity with the natural herbicide-sensitive protein
enzyme, differing only in two amino acids (Ref. 13). These minor
changes confer resistance of the enzyme to herbicidal pesticides that
inhibit ALS enzymes, which is what allows the GM-HRA protein to be used
as a selectable herbicide-tolerant marker in soybean transformation
events. The two amino acid substitutions found in the engineered GM-HRA
protein also occur as natural mutations in other commercially
available, non-genetically modified crop varieties that are tolerant to
ALS-inhibiting herbicides, and thus human exposure to the naturally
occurring protein, in addition to the proposed PIP inert, is
anticipated. The only route of human exposure that is likely, however,
is through the human diet, since the proposed PIP inert ingredient (and
the related naturally occurring ALS enzymes) is contained within plant
cells, which reduces potential human exposure via other routes to
negligible. Exposure via residential or lawn use is not expected
because the intended use sites are all agricultural. Though highly
unlikely, should residues of GM-HRA appear in drinking water as a
result of its use as a PIP inert ingredient in soybean, the risk to
humans would be very unlikely, based on the protein's lack of mammalian
toxicity demonstrated in the acute oral toxicity study and the lack of
amino acid similarity with
[[Page 9320]]
known protein toxins and allergens (see Unit III).
V. Cumulative Effects From Substances With a Common Mechanism of
Toxicity
Section 408(b)(2)(D)(v) of FFDCA requires that, when considering
whether to establish, modify, or revoke a tolerance, the Agency
consider ``available information'' concerning the cumulative effects of
a particular pesticide's residues and ``other substances that have a
common mechanism of toxicity.''
Based on the results of acute toxicity testing, EPA concluded that
the proposed PIP inert, GM-HRA, is not toxic. EPA also concluded that
no toxic or allergenic metabolites are produced in soybean or other
edible crops from the activity of this catabolic enzyme. In addition,
GM-HRA as encoded by the gm-hra gene was previously evaluated for its
safety by the U.S. Food and Drug Administration (FDA) in two other
transgenic soybean events. In one event, the gene was modified to
produce high oleic soybean oil (OECD Unique ID No. DP-3[Oslash]5423-1),
and the other provided glyphosate and ALS-inhibiting herbicide
tolerance (OECD Unique ID No. DP-356[Oslash]43-5) (Refs.14 and 15).
Based upon the information submitted, FDA concluded that the safety
profiles of these soybean events, the GM-HRA protein were not
materially different from that of other marketed soybean varieties, and
no safety concerns with the protein were identified (Refs.16 and 17).
EPA concludes that there are no cumulative effects associated with
GM-HRA expected from the proposed use as a PIP inert ingredient in
soybean. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S. Population, Infants and Children
The data submitted and cited regarding potential health effects for
the GM-HRA protein include the characterization of the expressed GM-HRA
protein in soybean, as well as the acute oral toxicity, amino acid
sequence comparisons, and in vitro digestibility study. The results of
these studies were used to evaluate human risk, and the validity,
completeness, and reliability of the available data from the studies
was considered.
As discussed in unit III, the acute oral toxicity data submitted
supports the prediction that the GM-HRA protein would be nontoxic to
humans. Moreover, amino acid sequence analysis demonstrated that GM-HRA
was not similar to any known protein toxin or allergen. Other data
considered as part of the allergenicity assessment included: The
structural and functional similarity of GM-HRA protein with naturally
occurring ALS proteins from soybean and other food crops; the ALS
proteins are not associated with food allergenicity; the protein
rapidly degraded in the highly acidic digestibility study; and GM-HRA
protein not glycosylated when expressed in the plant. GM-HRA protein is
therefore not expected to be a human allergen.
Finally, and specifically with regard to infants and children,
FFDCA section 408(b)(2)(C) provides that EPA shall assess the available
information about consumption patterns among infants and children,
special susceptibility of infants and children to pesticide chemical
residues, and the cumulative effects on infants and children of the
residues and other substances with a common mechanism of toxicity. In
addition, FFDCA section 408(b)(2)(C) provides that EPA shall apply an
additional tenfold margin of safety for infants and children in the
case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the data base unless EPA determines
that a different margin of safety will be safe for infants and
children.
Based on its review and consideration of all the available
information, the Agency concludes that there is a reasonable certainty
that no harm will result to the U.S. population, including infants and
children, from aggregate exposure to residues of the GM-HRA protein and
the genetic material necessary for its production when used as a PIP
inert ingredient in or on food and feed commodities of soybean. This
includes all anticipated dietary exposures and all other exposures for
which there is reliable information. The Agency has also concluded, for
the reasons discussed in more detail above, that there are no threshold
effects of concern and, as a result, that an additional margin of
safety for infants and children is unnecessary in this instance.
VII. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for GM-HRA protein in soybean.
VIII. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established for residues of Glycine max herbicide-resistant
acetolactate synthase (GM-HRA) enzyme in or on the food and feed
commodities of soybean when used as a plant-incorporated protectant
inert ingredient.

X. Statutory and Executive Order Reviews
This final rule establishes a tolerance under FFDCA section 408(d)
in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this final rule has
been exempted from review under Executive Order 12866, this final rule
is not subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This final rule does not contain
any information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA) (15 U.S.C. 272 note).
XI. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
