ACTION: Final rule.
AGENCY:
SUMMARY: This regulation establishes an
exemption from the requirement of a
tolerance for residues of the Bacillus
thuringiensis Cry 1A.105 protein in or
on corn when used as a plant–
incorporated protectant in the food and
feed commodities of corn; corn, field;
corn, sweet; and corn, pop. Monsanto
Company submitted a petition to EPA
under the Federal Food, Drug, and
Cosmetic Act (FFDCA), as amended by
the Food Quality Protection Act of 1996
(FQPA), requesting to amend the
existing temporary tolerance in 40 CFR
174.502 for the Bacillus thuringiensis
Cry 1A.105 protein to establish a
permanent exemption from the
requirement of a tolerance for residues
of the Bacillus thuringiensis Cry 1A.105
protein in or on all food commodities
when used as a plant-incorporated
protectant in all food commodities. This
regulation eliminates the need to
establish a maximum permissible level
for residues of the Bacillus thuringiensis
Cry 1A.105 insecticidal protein in or on
the food and feed commodities of corn;
corn, field; corn, sweet; and corn, pop.

II. Background and Statutory Findings
In the Federal Register of August 1,
2007 (72 FR 42075) (FRL–8129–8), EPA
issued a notice pursuant to section
408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide tolerance petition (PP 6F7142)
by Monsanto Company, 800 North
Lindbergh Blvd. St. Louis, MO 63167.
The petition requested that 40 CFR part
174 be amended by establishing an
exemption from the requirement of a
tolerance for residues of the Bacillus
thuringiensis Cry 1A.105 protein in or
on all food commodities when used as
plant–incorporated protectant in all
food commodities. This notice included
a summary of the petition prepared by
the petitioner Monsanto Company. One
commenter objected to the petition,
expressing concerns about Monsanto
obtaining an exemption from tolerance
and potential harmful effects. The
Agency understands the commenter’s
concerns about potential effects of this
particular plant-incorporated protectant
to humans and the environment.
Pursuant to its authority under the
FFDCA, EPA conducted a
comprehensive assessment of Cry
1A.105 protein, including a review of
acute oral toxicity data on Cry 1A.105
protein, amino acid sequence
comparisons to known toxins and
allergens, as well as data demonstrating
that Cry 1A.105 protein is rapidly
degraded by gastric fluid in vitro, is not
glycosylated, and is present at low
levels in the tissues expressing the
plant-incorporated protectant. Based on
these data, the Agency has concluded
that there is a reasonable certainty that
no harm will result from dietary
exposure to residues of Cry1A.105
protein in the food and feed
commodities of corn; corn, field; corn,
sweet; and corn, pop, when used as a
plant-incorporated protectant. Thus,
under the standard in FFDCA section
408(b)(2), a tolerance exemption is
appropriate. In taking this action, EPA,
pursuant to its authority under section
408(d)(4)(A)(i) of the FFDCA, is issuing
PO 00000
Frm 00043
Fmt 4700
Sfmt 4700
40757
a final regulation that varies from the
regulation sought by Monsanto in its
petition. Specifically, instead of issuing
a tolerance exemption that covers
residues of the subject plantincorporated protectant in all food
commodities, EPA is issuing a tolerance
exemption that covers residues of the
subject plant-incorporated protectant in
those commodities in which it will be
used as a plant-incorporated
protectant— in this case, the food and
feed commodities of corn; corn, field;
corn, sweet; and corn, pop. In this way,
the tolerance exemption is coextensive
with the registered uses for this
particular plant-incorporated protectant.
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
section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an
exemption from the requirement of a
tolerance, EPA must take into account
the factors set forth in section
408(b)(2)(C) of FFDCA, 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, section 408(b)(2)(D) of
FFDCA 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 section 408(b)(2)(D)
of FFDCA, EPA has reviewed the
available scientific data and other
E:\FR\FM\16JYR1.SGM
16JYR1
dwashington3 on PRODPC61 with RULES
40758
Federal Register / Vol. 73, No. 137 / Wednesday, July 16, 2008 / Rules and Regulations
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.
Mammalian Toxicity and
Allergenicity Assessment. Monsanto has
submitted acute oral toxicity data
demonstrating the lack of mammalian
toxicity at high levels of exposure to the
pure Cry1A.105 protein. These data
demonstrate the safety of the product at
a level well above maximum possible
exposure levels that are reasonably
anticipated in corn using submitted
Cry1A.105 expression values. Basing
this conclusion on acute oral toxicity
data without requiring further toxicity
testing and residue data is similar to the
Agency position regarding toxicity
testing and the requirement of residue
data for the microbial Bacillus
thuringiensis products from which this
plant-incorporated protectant was
derived (See 40 CFR 158.2130). For
microbial products, further toxicity
testing and residue data are triggered by
significant adverse acute effects in
studies such as the mouse oral toxicity
study, to verify the observed adverse
effects and clarify the source of these
effects (Tiers II & III).
An acute oral toxicity study in mice
(MRID 46694603) indicated that
Cry1A.105 is non-toxic to humans. The
oral LD50 for mice was greater than
2,072 milligrams/kiligrams (mg/kg)
bodyweight. This dose level is above
2,000 mg/kg, which is above the limit
dose (i.e., the highest dose used in acute
toxicity testing).
When proteins are toxic, they are
known to act via acute mechanisms and
at very low dose levels (Sjoblad, Roy D.,
et al., ‘‘Toxicological Considerations for
Protein Components of Biological
Pesticide Products,’’ Regulatory
Toxicology and Pharmacology 15, 3-9
(1992)). Therefore, since no acute effects
were shown to be caused by Cry1A.105,
even at relatively high dose levels, the
Cry1A.105 protein is not considered
toxic. Further, amino acid sequence
comparisons between the Cry1A.105
and known toxic proteins in protein
databases showed no similarities that
would raise a safety concern. In
addition, the Cry1A.105 protein was
shown to be substantially degraded by
heat when examined by immunoassay.
This instability to heat would also
lessen the potential dietary exposure to
intact Cry1A.105 protein in cooked or
processed foods. These biochemical
features along with the lack of adverse
VerDate Aug<31>2005
15:04 Jul 15, 2008
Jkt 214001
results in the acute oral toxicity test
support the conclusion that there is a
reasonable certainty no harm from
toxicity will result from dietary
exposure to residues of Cry1A.105 in or
on the identified corn commodities.
Since Cry1A.105 is a protein,
allergenic potential was also considered.
Currently, no definitive tests for
determining the allergenic potential of
novel proteins exist. Therefore, EPA
uses a weight-of- evidence approach
where the following factors are
considered: source of the trait; amino
acid sequence comparison with known
allergens; and biochemical properties of
the protein, including in vitro
digestibility in simulated gastric fluid
(SGF) and glycosylation. This approach
is consistent with the approach outlined
in the Annex to the Codex Alimentarius
‘‘Guideline for the Conduct of Food
Safety Assessment of Foods Derived
from Recombinant-DNA Plants.’’ The
allergenicity assessment for Cry1A.105
follows:
1. Source of the trait. Bacillus
thuringiensis is not considered to be a
source of allergenic proteins.
2. Amino acid sequence. A
comparison of the amino acid sequence
of Cry1A.105 with known allergens
showed no overall sequence similarity
(35% identity over 80 amino acids) or
identity at the level of eight contiguous
amino acid residues, indicating a lack of
potential linear epitopes found in
known food allergens.
3. Digestibility. The Cry1A.105
protein was digested within 30 seconds
in simulated gastric fluid containing
pepsin. The rapid degradation of
Cry1A.105 in the gastric environment
suggests little possible exposure to
intact protein in the intestinal lumen
where sensitization to food allergens
occurs.
4. Glycosylation. Cry1A.105 expressed
in corn was shown not to be
glycosylated.
5. Conclusion. Considering all of the
available information, EPA has
concluded that the potential for
Cry1A.105 to be a food allergen is
minimal.
The information on the safety of pure
Cry1A.105 protein provides adequate
justification to address possible
exposures in all corn crops.
IV. Aggregate Exposures
In examining aggregate exposure,
section 408 of FFDCA 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
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
pesticide use in gardens, lawns, or
buildings (residential and other indoor
uses.)
A. Dietary Exposure
The Agency has considered available
information on the aggregate exposure
levels of consumers (and major
identifiable subgroups of consumers) to
the pesticide chemical residue and to
other related substances. These
considerations include dietary exposure
under the tolerance exemption and all
other tolerances or exemptions in effect
for the plant-incorporated protectants
chemical residue, and exposure from
non-occupational sources. Exposure via
the skin or inhalation is not likely since
the plant- incorporated protectant is
contained within plant cells, which
essentially eliminates these exposure
routes or reduces these exposure routes
to negligible. In addition, even if
exposure can occur through inhalation,
the potential for Cry1A.105 to be an
allergen is low, as discussed in unit III.
Although the allergenicity assessment
focuses on potential to be a food
allergen, the data (comparing amino
acid sequence similarity to allergens,
including aeroallergens) also indicate a
low potential for Cry1A.105 to be an
inhalation allergen. Exposure via
residential or lawn use to infants and
children is also not expected because
the use sites for the Cry1A.105 protein
are agricultural. Oral exposure, at very
low levels, may occur from ingestion of
processed corn products and,
theoretically, drinking water. However
oral toxicity testing showed no adverse
effects.
Food. The data submitted and cited
regarding potential health effects for the
Cry1A.105 protein includes the
characterization of the expressed
Cry1A.105 protein in corn, as well as
the acute oral toxicity study, amino acid
sequence comparisons to known
allergens and toxins, and in vitro
digestibility of the protein. The results
of these studies were used to evaluate
human risk, and the validity,
completeness, and reliability of the
available data from the studies were also
considered.
Adequate information was submitted
to show that the Cry1A.105 test material
derived from microbial culture was
biochemically and functionally
equivalent to the protein produced by
the plant-incorporated protectant
ingredient in the plant. Microbially
produced protein was used in the
studies so that sufficient material for
testing was available.
The acute oral toxicity data submitted
support the prediction that the
Cry1A.105 protein would be non-toxic
E:\FR\FM\16JYR1.SGM
16JYR1
dwashington3 on PRODPC61 with RULES
Federal Register / Vol. 73, No. 137 / Wednesday, July 16, 2008 / Rules and Regulations
to humans. As mentioned in this unit,
when proteins are toxic, they are known
to act via acute mechanisms and at very
low dose levels (Sjoblad, Roy D., et al.,
‘‘Toxicological Considerations for
Protein Components of Biological
Pesticide Products,’’ Regulatory
Toxicology and Pharmacology 15, 3-9
(1992)). Since no treatment-related
adverse effects were shown to be caused
by the Cry1A.105 protein, even at
relatively high dose levels (e.g., 2072
mg/kg body weight), the Cry1A.105
protein is not considered toxic. Basing
this conclusion on acute oral toxicity
data without requiring further toxicity
testing or residue data is similar to the
Agency position regarding toxicity and
the requirement of residue data for the
microbial Bacillus thuringiensis
products from which this plantincorporated protectant was derived
(See 40 CFR 158.740(b)(2)(i)). For
microbial products, further toxicity
testing and residue data are triggered
when significant adverse effects are seen
in studies such as the acute oral toxicity
study. Further studies verify the
observed adverse effects and clarify the
source of these effects (Tiers II and III).
Residue chemistry data were not
required for a human health effects
assessment of the subject plantincorporated protectant because of the
lack of mammalian toxicity.
Nonetheless, data submitted
demonstrated low levels of the
Cry1A.105 protein in corn tissues (5-7
ppm in grain, 20-570 ppm in forage or
leaf tissue), indicating a low potential
for dietary exposure.
Since Cry1A.105 is a protein,
potential allergenicity is also considered
as part of the toxicity assessment.
Considering all of the available
information:
1. Cry1A.105 originates from a nonallergenic source;
2. Cry1A.105 has no sequence
similarities with known allergens;
3. Cry1A.105 is not glycosylated; and
4. Cry1A.105 is rapidly digested in
simulated gastric fluid; EPA has
concluded that the potential for
Cry1A.105 to be a food allergen is
minimal.
The genetic material necessary for the
production of the plant-incorporated
protectant active ingredient include the
nucleic acids (DNA, RNA) that encode
these proteins and regulatory regions.
The genetic material (DNA, RNA)
necessary for the production of the
Cry1A.105 protein has been exempted
from the requirement of a tolerance
under 40 CFR 174.507 (Nucleic acids
that are part of a plant-incorporated
protectant; exemption from the
requirement of a tolerance).

B. Other Non-Occupational Exposure
Dermal and Inhalation exposure.
Exposure via the skin or inhalation is
not likely since the plant-incorporated
protectant is contained within plant
cells, which essentially eliminates these
exposure routes or reduces these
exposure routes to negligible. In
addition, even if exposure can occur
through inhalation, the potential for
Cry1A.105 to be an allergen is minimal,
as discussed in this unit. Although the
allergenicity assessment focuses on
potential to be a food allergen, the data
also indicate a low potential for
Cry1A.105 to be an inhalation allergen.
V. Cumulative Effects
Pursuant to FFDCA section
408(b)(2)(D)(v), EPA has considered
available information on the cumulative
effects of such residues and other
substances that have a common
mechanism of toxicity. These
considerations included the cumulative
effects on infants and children of such
residues and other substances with a
common mechanism of toxicity.
Because there is no indication of
mammalian toxicity from the plantincorporated protectant, we conclude
that there are no cumulative effects for
the Cry1A.105 protein.
VI. Determination of Safety for U.S.
Population, 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) also 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 database unless
EPA determines that a different margin
of safety will be safe for infants and
children. In this instance, based on all
the available information, the Agency
concludes that there is a finding of no
toxicity for the Cry1A.105 protein.
Thus, there are no threshold effects of
concern and, as a result, the provision
requiring an additional tenfold margin
of safety does not apply. Further, the
considerations of consumption patterns,
special susceptibility, and cumulative
effects do not apply.
Neither available information
concerning the dietary consumption
patterns of consumers (and major
PO 00000
Frm 00045
Fmt 4700
Sfmt 4700
40759
identifiable subgroups of consumers
including infants and children) nor
safety factors that are generally
recognized as appropriate for the use of
animal experimentation data were
evaluated. The lack of mammalian
toxicity at high levels of exposure to the
Cry1A.105 protein, as well as the
minimal potential to be a food allergen,
demonstrate the safety of the product at
levels well above possible maximum
exposure levels anticipated.
VII. Other Considerations
A. Endocrine Disruptors
The pesticidal active ingredient is a
protein, derived from a source that is
not known to exert an influence on the
endocrine system. Therefore, the
Agency is not requiring information on
the endocrine effects of the plantincorporated protectant at this time.
B. Analytical Method
A standard operating procedure for an
enzyme-linked immunosorbent assay for
the detection and quantification of
Cry1A.105 in corn tissue has been
submitted.
C. Codex Maximum Residue Level
No Codex maximum residue level
exists for the plant-incorporated
protectant Bacillus thuringiensis
Cry1A.105 protein.
VIII. Conclusions
There is a reasonable certainty that no
harm will result from aggregate
exposure to the U.S. population,
including infants and children, to
residues of the Cry1A.105 protein in or
on all food and feed commodities of
corn; corn, field; corn, sweet; and corn,
pop. This includes all anticipated
dietary exposures and all other
exposures for which there is reliable
information. The Agency has arrived at
this conclusion because, as discussed in
this unit, no toxicity to mammals has
been observed, nor is there any
indication of allergenicity potential for
the plant-incorporated protectant.
IX. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
exemption under section 408(d) of
FFDCA 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,

This final rule does not contain any

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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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

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) (Public Law 104–4).
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), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).

II. Background and Statutory Findings
In the Federal Register of August 1, 2007 (72 FR 42075) (FRL-8129-
8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition (PP 6F7142) by Monsanto Company, 800 North Lindbergh Blvd. St.
Louis, MO 63167. The petition requested that 40 CFR part 174 be amended
by establishing an exemption from the requirement of a tolerance for
residues of the Bacillus thuringiensis Cry 1A.105 protein in or on all
food commodities when used as plant-incorporated protectant in all food
commodities. This notice included a summary of the petition prepared by
the petitioner Monsanto Company. One commenter objected to the
petition, expressing concerns about Monsanto obtaining an exemption
from tolerance and potential harmful effects. The Agency understands
the commenter's concerns about potential effects of this particular
plant-incorporated protectant to humans and the environment. Pursuant
to its authority under the FFDCA, EPA conducted a comprehensive
assessment of Cry 1A.105 protein, including a review of acute oral
toxicity data on Cry 1A.105 protein, amino acid sequence comparisons to
known toxins and allergens, as well as data demonstrating that Cry
1A.105 protein is rapidly degraded by gastric fluid in vitro, is not
glycosylated, and is present at low levels in the tissues expressing
the plant-incorporated protectant. Based on these data, the Agency has
concluded that there is a reasonable certainty that no harm will result
from dietary exposure to residues of Cry1A.105 protein in the food and
feed commodities of corn; corn, field; corn, sweet; and corn, pop, when
used as a plant-incorporated protectant. Thus, under the standard in
FFDCA section 408(b)(2), a tolerance exemption is appropriate. In
taking this action, EPA, pursuant to its authority under section
408(d)(4)(A)(i) of the FFDCA, is issuing a final regulation that varies
from the regulation sought by Monsanto in its petition. Specifically,
instead of issuing a tolerance exemption that covers residues of the
subject plant-incorporated protectant in all food commodities, EPA is
issuing a tolerance exemption that covers residues of the subject
plant-incorporated protectant in those commodities in which it will be
used as a plant-incorporated protectant-- in this case, the food and
feed commodities of corn; corn, field; corn, sweet; and corn, pop. In
this way, the tolerance exemption is coextensive with the registered
uses for this particular plant-incorporated protectant.
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 section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an exemption from the requirement
of a tolerance, EPA must take into account the factors set forth in
section 408(b)(2)(C) of FFDCA, 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, section 408(b)(2)(D) of FFDCA 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 section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other
[[Page 40758]]
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.
Mammalian Toxicity and Allergenicity Assessment. Monsanto has
submitted acute oral toxicity data demonstrating the lack of mammalian
toxicity at high levels of exposure to the pure Cry1A.105 protein.
These data demonstrate the safety of the product at a level well above
maximum possible exposure levels that are reasonably anticipated in
corn using submitted Cry1A.105 expression values. Basing this
conclusion on acute oral toxicity data without requiring further
toxicity testing and residue data is similar to the Agency position
regarding toxicity testing and the requirement of residue data for the
microbial Bacillus thuringiensis products from which this plant-
incorporated protectant was derived (See 40 CFR 158.2130). For
microbial products, further toxicity testing and residue data are
triggered by significant adverse acute effects in studies such as the
mouse oral toxicity study, to verify the observed adverse effects and
clarify the source of these effects (Tiers II & III).
An acute oral toxicity study in mice (MRID 46694603) indicated that
Cry1A.105 is non-toxic to humans. The oral LD50 for mice was
greater than 2,072 milligrams/kiligrams (mg/kg) bodyweight. This dose
level is above 2,000 mg/kg, which is above the limit dose (i.e., the
highest dose used in acute toxicity testing).
When proteins are toxic, they are known to act via acute mechanisms
and at very low dose levels (Sjoblad, Roy D., et al., ``Toxicological
Considerations for Protein Components of Biological Pesticide
Products,'' Regulatory Toxicology and Pharmacology 15, 3-9 (1992)).
Therefore, since no acute effects were shown to be caused by Cry1A.105,
even at relatively high dose levels, the Cry1A.105 protein is not
considered toxic. Further, amino acid sequence comparisons between the
Cry1A.105 and known toxic proteins in protein databases showed no
similarities that would raise a safety concern. In addition, the
Cry1A.105 protein was shown to be substantially degraded by heat when
examined by immunoassay. This instability to heat would also lessen the
potential dietary exposure to intact Cry1A.105 protein in cooked or
processed foods. These biochemical features along with the lack of
adverse results in the acute oral toxicity test support the conclusion
that there is a reasonable certainty no harm from toxicity will result
from dietary exposure to residues of Cry1A.105 in or on the identified
corn commodities.
Since Cry1A.105 is a protein, allergenic potential was also
considered. Currently, no definitive tests for determining the
allergenic potential of novel proteins exist. Therefore, EPA uses a
weight-of- evidence approach where the following factors are
considered: source of the trait; amino acid sequence comparison with
known allergens; and biochemical properties of the protein, including
in vitro digestibility in simulated gastric fluid (SGF) and
glycosylation. This approach is consistent with the approach outlined
in the Annex to the Codex Alimentarius ``Guideline for the Conduct of
Food Safety Assessment of Foods Derived from Recombinant-DNA Plants.''
The allergenicity assessment for Cry1A.105 follows:
1. Source of the trait. Bacillus thuringiensis is not considered to
be a source of allergenic proteins.
2. Amino acid sequence. A comparison of the amino acid sequence of
Cry1A.105 with known allergens showed no overall sequence similarity
(35% identity over 80 amino acids) or identity at the level of eight
contiguous amino acid residues, indicating a lack of potential linear
epitopes found in known food allergens.
3. Digestibility. The Cry1A.105 protein was digested within 30
seconds in simulated gastric fluid containing pepsin. The rapid
degradation of Cry1A.105 in the gastric environment suggests little
possible exposure to intact protein in the intestinal lumen where
sensitization to food allergens occurs.
4. Glycosylation. Cry1A.105 expressed in corn was shown not to be
glycosylated.
5. Conclusion. Considering all of the available information, EPA
has concluded that the potential for Cry1A.105 to be a food allergen is
minimal.
The information on the safety of pure Cry1A.105 protein provides
adequate justification to address possible exposures in all corn crops.
IV. Aggregate Exposures
In examining aggregate exposure, section 408 of FFDCA 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.)
A. Dietary Exposure
The Agency has considered available information on the aggregate
exposure levels of consumers (and major identifiable subgroups of
consumers) to the pesticide chemical residue and to other related
substances. These considerations include dietary exposure under the
tolerance exemption and all other tolerances or exemptions in effect
for the plant-incorporated protectants chemical residue, and exposure
from non-occupational sources. Exposure via the skin or inhalation is
not likely since the plant- incorporated protectant is contained within
plant cells, which essentially eliminates these exposure routes or
reduces these exposure routes to negligible. In addition, even if
exposure can occur through inhalation, the potential for Cry1A.105 to
be an allergen is low, as discussed in unit III. Although the
allergenicity assessment focuses on potential to be a food allergen,
the data (comparing amino acid sequence similarity to allergens,
including aeroallergens) also indicate a low potential for Cry1A.105 to
be an inhalation allergen. Exposure via residential or lawn use to
infants and children is also not expected because the use sites for the
Cry1A.105 protein are agricultural. Oral exposure, at very low levels,
may occur from ingestion of processed corn products and, theoretically,
drinking water. However oral toxicity testing showed no adverse
effects.
Food. The data submitted and cited regarding potential health
effects for the Cry1A.105 protein includes the characterization of the
expressed Cry1A.105 protein in corn, as well as the acute oral toxicity
study, amino acid sequence comparisons to known allergens and toxins,
and in vitro digestibility of the protein. The results of these studies
were used to evaluate human risk, and the validity, completeness, and
reliability of the available data from the studies were also
considered.
Adequate information was submitted to show that the Cry1A.105 test
material derived from microbial culture was biochemically and
functionally equivalent to the protein produced by the plant-
incorporated protectant ingredient in the plant. Microbially produced
protein was used in the studies so that sufficient material for testing
was available.
The acute oral toxicity data submitted support the prediction that
the Cry1A.105 protein would be non-toxic
[[Page 40759]]
to humans. As mentioned in this unit, when proteins are toxic, they are
known to act via acute mechanisms and at very low dose levels (Sjoblad,
Roy D., et al., ``Toxicological Considerations for Protein Components
of Biological Pesticide Products,'' Regulatory Toxicology and
Pharmacology 15, 3-9 (1992)). Since no treatment-related adverse
effects were shown to be caused by the Cry1A.105 protein, even at
relatively high dose levels (e.g., 2072 mg/kg body weight), the
Cry1A.105 protein is not considered toxic. Basing this conclusion on
acute oral toxicity data without requiring further toxicity testing or
residue data is similar to the Agency position regarding toxicity and
the requirement of residue data for the microbial Bacillus
thuringiensis products from which this plant-incorporated protectant
was derived (See 40 CFR 158.740(b)(2)(i)). For microbial products,
further toxicity testing and residue data are triggered when
significant adverse effects are seen in studies such as the acute oral
toxicity study. Further studies verify the observed adverse effects and
clarify the source of these effects (Tiers II and III).
Residue chemistry data were not required for a human health effects
assessment of the subject plant-incorporated protectant because of the
lack of mammalian toxicity. Nonetheless, data submitted demonstrated
low levels of the Cry1A.105 protein in corn tissues (5-7 ppm in grain,
20-570 ppm in forage or leaf tissue), indicating a low potential for
dietary exposure.
Since Cry1A.105 is a protein, potential allergenicity is also
considered as part of the toxicity assessment. Considering all of the
available information:
1. Cry1A.105 originates from a non-allergenic source;
2. Cry1A.105 has no sequence similarities with known allergens;
3. Cry1A.105 is not glycosylated; and
4. Cry1A.105 is rapidly digested in simulated gastric fluid; EPA
has concluded that the potential for Cry1A.105 to be a food allergen is
minimal.
The genetic material necessary for the production of the plant-
incorporated protectant active ingredient include the nucleic acids
(DNA, RNA) that encode these proteins and regulatory regions. The
genetic material (DNA, RNA) necessary for the production of the
Cry1A.105 protein has been exempted from the requirement of a tolerance
under 40 CFR 174.507 (Nucleic acids that are part of a plant-
incorporated protectant; exemption from the requirement of a
tolerance).
B. Other Non-Occupational Exposure
Dermal and Inhalation exposure. Exposure via the skin or inhalation
is not likely since the plant-incorporated protectant is contained
within plant cells, which essentially eliminates these exposure routes
or reduces these exposure routes to negligible. In addition, even if
exposure can occur through inhalation, the potential for Cry1A.105 to
be an allergen is minimal, as discussed in this unit. Although the
allergenicity assessment focuses on potential to be a food allergen,
the data also indicate a low potential for Cry1A.105 to be an
inhalation allergen.
V. Cumulative Effects
Pursuant to FFDCA section 408(b)(2)(D)(v), EPA has considered
available information on the cumulative effects of such residues and
other substances that have a common mechanism of toxicity. These
considerations included the cumulative effects on infants and children
of such residues and other substances with a common mechanism of
toxicity. Because there is no indication of mammalian toxicity from the
plant-incorporated protectant, we conclude that there are no cumulative
effects for the Cry1A.105 protein.
VI. Determination of Safety for U.S. Population, 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) also 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 database unless EPA determines
that a different margin of safety will be safe for infants and
children. In this instance, based on all the available information, the
Agency concludes that there is a finding of no toxicity for the
Cry1A.105 protein. Thus, there are no threshold effects of concern and,
as a result, the provision requiring an additional tenfold margin of
safety does not apply. Further, the considerations of consumption
patterns, special susceptibility, and cumulative effects do not apply.
Neither available information concerning the dietary consumption
patterns of consumers (and major identifiable subgroups of consumers
including infants and children) nor safety factors that are generally
recognized as appropriate for the use of animal experimentation data
were evaluated. The lack of mammalian toxicity at high levels of
exposure to the Cry1A.105 protein, as well as the minimal potential to
be a food allergen, demonstrate the safety of the product at levels
well above possible maximum exposure levels anticipated.
VII. Other Considerations
A. Endocrine Disruptors
The pesticidal active ingredient is a protein, derived from a
source that is not known to exert an influence on the endocrine system.
Therefore, the Agency is not requiring information on the endocrine
effects of the plant-incorporated protectant at this time.
B. Analytical Method
A standard operating procedure for an enzyme-linked immunosorbent
assay for the detection and quantification of Cry1A.105 in corn tissue
has been submitted.
C. Codex Maximum Residue Level
No Codex maximum residue level exists for the plant-incorporated
protectant Bacillus thuringiensis Cry1A.105 protein.
VIII. Conclusions
There is a reasonable certainty that no harm will result from
aggregate exposure to the U.S. population, including infants and
children, to residues of the Cry1A.105 protein in or on all food and
feed commodities of corn; corn, field; corn, sweet; and corn, pop. This
includes all anticipated dietary exposures and all other exposures for
which there is reliable information. The Agency has arrived at this
conclusion because, as discussed in this unit, no toxicity to mammals
has been observed, nor is there any indication of allergenicity
potential for the plant-incorporated protectant.
IX. Statutory and Executive Order Reviews
This final rule establishes a tolerance exemption under section
408(d) of FFDCA 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,
[[Page 40760]]
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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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) (Public Law 104-4).
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), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
X. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. 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 this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
