II. Background and Statutory Findings
In the Federal Register of January 25,
2006 (71 FR 4140) (FRL–7757–6), EPA
issued a notice pursuant to section
408(d)(3) of the FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide tolerance petition (PP 4G6808)
by Syngenta Seeds, Inc., P.O. Box
12257, 3054 East Cornwallis Road,
Research Triangle Park, NC 27709–2257.
The petition requested that 40 CFR part
174 be amended by extending by 1 year
a temporary exemption from the
requirement of a tolerance for residues
of Bacillus thuringiensis modified
Cry3A protein (mCry3A) and the genetic
material necessary for its production in
corn on field corn, sweet corn, and
popcorn when applied/used as a plantincorporated protectant (40 CFR
174.456). This notice included a
summary of the petition prepared by the
petitioner Syngenta Seeds, Inc.. One
comment was received in response to
the notice of filing. The commentor
objected to an exemption from the
requirement of a tolerance, stated that
she does not favor genetically
engineered corn, and objected to the
lack of long term tests. The Agency
understands the commenter’s concerns
and recognizes that some individuals
believe that genetically modified crops
and food should be banned completely.
Regarding the commenter’s concern
VerDate Aug<31>2005
20:10 Mar 14, 2006
Jkt 208001
regarding a lack of long term tests; 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 effects were shown to
be caused by the plant-incorporated
protectants, even at relatively high dose
levels, the mCry3A protein is not
considered toxic. Pursuant to its
authority under the FFDCA, EPA
conducted a comprehensive assessment
of the modified Cry3A protein and the
genetic material necessary for its
production in corn, including a review
of acute oral toxicity data on the
mCry3A protein, amino acid sequence
comparisons to known toxins and
allergens, as well as data demonstrating
that the mCry3A protein is rapidly
degraded by gastric fluid in vitro, is not
glycosylated, is inactivated when heated
to 95 °C for 30 minutes, and is present
in low levels in corn tissue, and has
concluded that there is a reasonable
certainty that no harm will result from
dietary exposure to this protein as
expressed in genetically modified corn.
Section 408(c)(2)(A)(i) of the 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 the 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), 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), 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 the 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 the FFDCA, 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.
Data have been submitted
demonstrating the lack of mammalian
toxicity at high levels of exposure to the
pure mCry3A protein. These data
demonstrate the safety of the products at
levels well above maximum possible
exposure levels that are reasonably
anticipated in the crops. This 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 by
significant acute effects in studies such
as the mouse oral toxicity study, to
verify the observed effects and clarify
the source of these effects (Tiers II and
III).
An acute oral toxicity study was
submitted for the mCry3A protein. The
acute oral toxicity data submitted
support the prediction that the mCry3A
protein would be non-toxic to humans.
Male and female mice (5 of each) were
dosed with 2,377 milligrams/kilograms
bodyweight (mg/kg bwt) of mCry3A
protein. With the exception of one
female in the test group that was
euthanized on day 2 (due to adverse
clinical signs consistent with a dosing
injury), all other mice survived the
study, gained weight, had no test
material-related clinical signs, and had
no test material-related findings at
necropsy.
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 effects were
E:\FR\FM\15MRR1.SGM
15MRR1

cchase on PROD1PC60 with RULES
shown to be caused by the plantincorporated protectants, even at
relatively high dose levels, the mCry3A
protein is not considered toxic. Further,
amino acid sequence comparisons
showed no similarity between the
mCry3A protein to known toxic proteins
available in public protein data bases.
Since mCry3A is a protein, allergenic
sensitivities were considered. Current
scientific knowledge suggests that
common food allergens tend to be
resistant to degradation by heat, acid,
and proteases; may be glycosylated; and
present at high oncentrations in the
food.
Data have been submitted that
demonstrate that the mCry3A protein is
rapidly degraded by gastric fluid in
vitro. In a solution of simulated gastric
fluid 1 milligrams/milliliter (mg/mL)
mCry3A test protein mixed with
simulated gastric fluid (pH 1.2,
containing 2 mg/mL NaCl, 14 muL 6 N
HCl, and 2.7 mg/mL pepsin) resulting in
10 pepsin activity units/ mug protein
(complies with year 2000 U.S.
Pharmacopoeia recommendations),
complete degradation of detectable
mCry3A protein occurred within 2
minutes. A comparison of amino acid
sequences of known allergens
uncovered no evidence of any homology
with mCry3A, even at the level of eight
contiguous amino acids residues.
Further, data demonstrate that mCry3A
is not glycosylated, is inactivated when
heated to 95 °C for 30 minutes, and is
present in low levels in corn tissue.
Therefore, the potential for the mCry3A
protein to be a food allergens is
minimal. As noted above, toxic proteins
typically act as acute toxins with low
dose levels. Therefore, since no effects
were shown to be caused by the plantincorporated protectant, even at
relatively high dose levels, the mCry3A
protein is not considered toxic.
IV. Aggregate Exposures
In examining aggregate exposure,
section 408 of the 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
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) to
the pesticide chemical residue and to
other related substances. These
considerations include dietary exposure
under the tolerance exemption and all
VerDate Aug<31>2005
20:10 Mar 14, 2006
Jkt 208001
other tolerances or exemptions in effect
for the plant-incorporated protectant
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. Exposure via residential or
lawn use to infants and children is also
not expected because the use sites for
the mCry3A protein are all agricultural
for control of insects. Oral exposure, at
very low levels, may occur from
ingestion of processed corn products
and, potentially, drinking water.
However, oral toxicity testing done at a
dose in excess of 2 grams/kilogram (gm/
kg) showed no adverse effects.
Furthermore, the expression of the
modified Cry3A protein in corn kernals
has been shown to be in the parts per
million range, which makes the
expected dietary exposure several
orders of magnitude lower than the
amounts of mCry3A protein shown to
have no toxicity. Therefore, even if
negligible aggregate exposure should
occur, the Agency concludes that such
exposure would prevent no harm due to
the lack of mammalian toxicity and the
rapid digestibility demonstrated for the
mCry3A protein.
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, resulting from the
plant-incorporated protectant, we
conclude that there are no cumulative
effects for the mCry3A protein.
VI. Determination of Safety for U.S.
Population, Infants and Children
A. Toxicity and Allergenicity
Conclusions
The data submitted and cited
regarding potential health effects for the
mCry3A protein include the
characterization of the expressed
mCry3A protein in corn, as well as the
acute oral toxicity, and in vitro
digestibility of the proteins. The results
of these studies were determined
applicable to evaluate human risk, and
the validity, completeness, and
reliability of the available data from the
studies were considered.

Adequate information was submitted
to show that the mCry3A protein test
material derived from microbial cultures
was biochemically and functionally
similar to the protein produced by the
plant-incorporated protectant
ingredients in corn. Production of
microbially produced protein was
chosen in order to obtain sufficient
material for testing.
The acute oral toxicity data submitted
supports the prediction that the mCry3A
protein would be non-toxic to humans.
As mentioned above, 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
effects were shown to be caused by
mCry3A protein, even at relatively high
dose levels (2,377 mg/kg bwt), the
mCry3A protein is not considered toxic.
This 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 by significant
acute effects in studies such as the
mouse oral toxicity study to verify the
observed effects and clarify thesource of
these effects (Tiers II and III).
MCry3A protein residue chemistry
data were not required for a human
health effects assessment of the subject
plant-incorporated protectant
ingredients because of the lack of
mammalian toxicity. However, data
submitted demonstrated low levels of
mCry3A in corn tissues with less than
2 micrograms mCry3A protein/gram dry
weight in kernals and less than 30
micrograms mCry3A protein/gram dry
weight of whole corn plant.
Since modified Cry3A is a protein, its
potential allergenicity is also considered
as part of the toxicity assessment. Data
considered as part of the allergenicity
assessment include that the modified
Cry3A protein came from Bacillus
thuringiensis which is not a known
allergenic source, showed no sequence
similarity to known allergens, was
readily degraded by pepsin, was
inactivated by heat and was not
glycosylated when expressed in the
plant. Therefore, there is a reasonable
certainty that modified Cry3A protein
will not be an allergen.
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
mCry3A 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 in the crop.
The genetic material necessary for the
production of the plant-incorporated
protectant active ingredients are the
nucleic acids (DNA, RNA) which
comprise genetic material encoding
these proteins and their regulatory
regions. The genetic material (DNA,
RNA), necessary for theproduction of
mCry3A protein has been exempted
under the blanket exemption for all
nucleic acids (40 CFR 174.475).

B. Infants and Children Risk
Conclusions
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, also referred to as margins of
exposure (MOEs), 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 MOE 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 mCry3A protein and the
genetic material necessary for their
production. Thus, there are no threshold
effects of concern to infants and
children when the mCry3A protein is
used as a plant-incorporated protectant.
Accordingly, the Agency concludes that
the additional MOE is not necessary to
protect infants and children, and that
not adding any additional MOE will be
safe for infants and children.
C. Overall Safety Conclusion
There is a reasonable certainty that no
harm will result from aggregate
exposure to the U.S. population,
including infants and children, to the
mCry3A protein and the genetic
material necessary for its production.
This includes all anticipated dietary
VerDate Aug<31>2005
20:10 Mar 14, 2006
Jkt 208001
exposures and all other exposures for
which there is reliable information.
The Agency has arrived at this
conclusion because, as discussed above,
no toxicity to mammals has been
observed, nor any indication of
allergenicity potential for the plantincorporated protectant.
VII. Other Considerations
A. Endocrine Disruptors
The pesticidal active ingredient is a
protein, derived from sources that are
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(s)
A method for extraction and ELISA
analysis of mCry3A protein in corn has
been submitted and found acceptable by
the Agency.
C. Codex Maximum Residue Level
No Codex maximum residue levels
exist for the plant-incorporated
protectant Bacillus thuringiensis
mCry3A protein and the genetic
material necessary for its production in
corn.
VIII. Objections and Hearing Requests
Under section 408(g) of the FFDCA, as
amended by the FQPA, any person may
file an objection to any aspect of this
regulation and may also request a
hearing on those objections. The EPA
procedural regulations which govern the
submission of objections and requests
for hearings appear in 40 CFR part 178.
Although the procedures in those
regulations require some modification to
reflect the amendments made to the
FFDCA by the FQPA, EPA will continue
to use those procedures, with
appropriate adjustments, until the
necessary modifications can be made.
The new section 408(g) of the FFDCA
provides essentially the same process
for persons to ‘‘object’’ to a regulation
for an exemption from the requirement
of a tolerance issued by EPA under new
section 408(d), as was provided in the
old sections 408 and 409 of the FFDCA.
However, the period for filing objections
is now 60 days, rather than 30 days.

B. When Will the Agency Grant a
Request for a Hearing?
A request for a hearing will be granted
if the Administrator determines that the
material submitted shows the following:
There is a genuine and substantial issue
of fact; there is a reasonable possibility
that available evidence identified by the
requestor would, if established resolve
one or more of such issues in favor of
the requestor, taking into account
uncontested claims or facts to the
contrary; and resolution of the factual
issues(s) in the manner sought by the
requestor would be adequate to justify
the action requested (40 CFR 178.32).
IX. Statutory and Executive Order
Reviews
This final rule establishes a temporary
exemption from the tolerance
requirement under section 408(d) of the
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 rule has been exempted
from review under Executive Order
12866 due to its lack of significance,
this rule is not subject to Executive
Order 13211, Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use (66
FR 28355, May 22, 2001). 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., or 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). 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); or OMB review or any Agency
action under Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
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). Since
tolerances and exemptions that are
established on the basis of a petition
VerDate Aug<31>2005

under section 408(d) of the FFDCA,
such as the exemption 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. In
addition, the Agency has determined
that this action will not have a
substantial direct effect on States, on the
relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999). Executive Order 13132 requires
EPA to develop an accountable process
to ensure ‘‘meaningful and timely input
by State and local officials in the
development of regulatory policies that
have federalism implications.’’ ‘‘Policies
that have federalism implications’’ is
defined in the Executive order to
include regulations that have
‘‘substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government.’’ This final rule
directly regulates growers, food
processors, food handlers and food
retailers, not States. This action does not
alter the relationships or distribution of
power and responsibilities established
by Congress in the preemption
provisions of section 408(n)(4) of the
FFDCA. For these same reasons, the
Agency has determined that this rule
does not have any ‘‘tribal implications’’
as described in Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 6, 2000). Executive
Order 13175, requires EPA to develop
an accountable process to ensure
‘‘meaningful and timely input by tribal
officials in the development of
regulatory policies that have tribal
implications.’’ ‘‘Policies that have tribal
implications’’ is defined in the
Executive order to include regulations
that have ‘‘substantial direct effects on
one or more Indian tribes, on the
relationship between the Federal
Government and the Indian tribes, or on
the distribution of power and
responsibilities between the Federal
Government and Indian tribes.’’ This
rule will not have substantial direct
effects on tribal governments, on the
relationship between the Federal
Government and Indian tribes, or on the
distribution of power and
responsibilities between the Federal
government and Indian tribes, as
specified in Executive Order 13175.

X. Congressional Review Act
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
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).

II. Background and Statutory Findings
In the Federal Register of January 18,
2006 (71 FR 2930) (FRL–7757–1), 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 petition (PP 3E6535) by IR-4,
681 U.S. Highway #1 South, North
Brunswick, NJ 08902. The petition
requested that 40 CFR 180.476 be
amended by establishing a tolerance for
combined residues of the fungicide
triflumizole, 1-(1-((4-chloro-2(trifluoromethyl)phenyl)imino-2propoxyethyl]-1H-imidazole, and its
metabolites containing the 4-chloro-2trifluoromethylaniline moiety,
calculated as the parent compound in or
on filberts at 0.05 parts per million
(ppm). That notice included a summary
of the petition prepared by Chemtura,
the registrant. There were no comments
received in response to the notice of
filing.
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(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. Section
408(b)(2)(C) of FFDCA requires 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. . . .’’

II. Background and Statutory Findings
In the Federal Register of January 25, 2006 (71 FR 4140) (FRL-7757-
6), EPA issued a notice pursuant to section 408(d)(3) of the FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition (PP 4G6808) by Syngenta Seeds, Inc., P.O. Box 12257, 3054 East
Cornwallis Road, Research Triangle Park, NC 27709-2257. The petition
requested that 40 CFR part 174 be amended by extending by 1 year a
temporary exemption from the requirement of a tolerance for residues of
Bacillus thuringiensis modified Cry3A protein (mCry3A) and the genetic
material necessary for its production in corn on field corn, sweet
corn, and popcorn when applied/used as a plant-incorporated protectant
(40 CFR 174.456). This notice included a summary of the petition
prepared by the petitioner Syngenta Seeds, Inc.. One comment was
received in response to the notice of filing. The commentor objected to
an exemption from the requirement of a tolerance, stated that she does
not favor genetically engineered corn, and objected to the lack of long
term tests. The Agency understands the commenter's concerns and
recognizes that some individuals believe that genetically modified
crops and food should be banned completely. Regarding the commenter's
concern regarding a lack of long term tests; 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 effects were shown to be
caused by the plant-incorporated protectants, even at relatively high
dose levels, the mCry3A protein is not considered toxic. Pursuant to
its authority under the FFDCA, EPA conducted a comprehensive assessment
of the modified Cry3A protein and the genetic material necessary for
its production in corn, including a review of acute oral toxicity data
on the mCry3A protein, amino acid sequence comparisons to known toxins
and allergens, as well as data demonstrating that the mCry3A protein is
rapidly degraded by gastric fluid in vitro, is not glycosylated, is
inactivated when heated to 95 [deg]C for 30 minutes, and is present in
low levels in corn tissue, and has concluded that there is a reasonable
certainty that no harm will result from dietary exposure to this
protein as expressed in genetically modified corn.
Section 408(c)(2)(A)(i) of the 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 the 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), 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), 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 the 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 the FFDCA, 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.
Data have been submitted demonstrating the lack of mammalian
toxicity at high levels of exposure to the pure mCry3A protein. These
data demonstrate the safety of the products at levels well above
maximum possible exposure levels that are reasonably anticipated in the
crops. This 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 by significant
acute effects in studies such as the mouse oral toxicity study, to
verify the observed effects and clarify the source of these effects
(Tiers II and III).
An acute oral toxicity study was submitted for the mCry3A protein.
The acute oral toxicity data submitted support the prediction that the
mCry3A protein would be non-toxic to humans. Male and female mice (5 of
each) were dosed with 2,377 milligrams/kilograms bodyweight (mg/kg bwt)
of mCry3A protein. With the exception of one female in the test group
that was euthanized on day 2 (due to adverse clinical signs consistent
with a dosing injury), all other mice survived the study, gained
weight, had no test material-related clinical signs, and had no test
material-related findings at necropsy.
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 effects were
[[Page 13271]]
shown to be caused by the plant-incorporated protectants, even at
relatively high dose levels, the mCry3A protein is not considered
toxic. Further, amino acid sequence comparisons showed no similarity
between the mCry3A protein to known toxic proteins available in public
protein data bases.
Since mCry3A is a protein, allergenic sensitivities were
considered. Current scientific knowledge suggests that common food
allergens tend to be resistant to degradation by heat, acid, and
proteases; may be glycosylated; and present at high oncentrations in
the food.
Data have been submitted that demonstrate that the mCry3A protein
is rapidly degraded by gastric fluid in vitro. In a solution of
simulated gastric fluid 1 milligrams/milliliter (mg/mL) mCry3A test
protein mixed with simulated gastric fluid (pH 1.2, containing 2 mg/mL
NaCl, 14 muL 6 N HCl, and 2.7 mg/mL pepsin) resulting in 10 pepsin
activity units/ mug protein (complies with year 2000 U.S. Pharmacopoeia
recommendations), complete degradation of detectable mCry3A protein
occurred within 2 minutes. A comparison of amino acid sequences of
known allergens uncovered no evidence of any homology with mCry3A, even
at the level of eight contiguous amino acids residues. Further, data
demonstrate that mCry3A is not glycosylated, is inactivated when heated
to 95 [deg]C for 30 minutes, and is present in low levels in corn
tissue. Therefore, the potential for the mCry3A protein to be a food
allergens is minimal. As noted above, toxic proteins typically act as
acute toxins with low dose levels. Therefore, since no effects were
shown to be caused by the plant-incorporated protectant, even at
relatively high dose levels, the mCry3A protein is not considered
toxic.
IV. Aggregate Exposures
In examining aggregate exposure, section 408 of the 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).
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 protectant 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. Exposure via residential
or lawn use to infants and children is also not expected because the
use sites for the mCry3A protein are all agricultural for control of
insects. Oral exposure, at very low levels, may occur from ingestion of
processed corn products and, potentially, drinking water. However, oral
toxicity testing done at a dose in excess of 2 grams/kilogram (gm/kg)
showed no adverse effects. Furthermore, the expression of the modified
Cry3A protein in corn kernals has been shown to be in the parts per
million range, which makes the expected dietary exposure several orders
of magnitude lower than the amounts of mCry3A protein shown to have no
toxicity. Therefore, even if negligible aggregate exposure should
occur, the Agency concludes that such exposure would prevent no harm
due to the lack of mammalian toxicity and the rapid digestibility
demonstrated for the mCry3A protein.
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,
resulting from the plant-incorporated protectant, we conclude that
there are no cumulative effects for the mCry3A protein.
VI. Determination of Safety for U.S. Population, Infants and Children
A. Toxicity and Allergenicity Conclusions
The data submitted and cited regarding potential health effects
for the mCry3A protein include the characterization of the expressed
mCry3A protein in corn, as well as the acute oral toxicity, and in
vitro digestibility of the proteins. The results of these studies were
determined applicable to evaluate human risk, and the validity,
completeness, and reliability of the available data from the studies
were considered.
Adequate information was submitted to show that the mCry3A protein
test material derived from microbial cultures was biochemically and
functionally similar to the protein produced by the plant-incorporated
protectant ingredients in corn. Production of microbially produced
protein was chosen in order to obtain sufficient material for testing.
The acute oral toxicity data submitted supports the prediction
that the mCry3A protein would be non-toxic to humans. As mentioned
above, 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 effects were shown to be caused by mCry3A protein,
even at relatively high dose levels (2,377 mg/kg bwt), the mCry3A
protein is not considered toxic. This 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 by significant acute effects in studies such as the mouse
oral toxicity study to verify the observed effects and clarify
thesource of these effects (Tiers II and III).
MCry3A protein residue chemistry data were not required for a
human health effects assessment of the subject plant-incorporated
protectant ingredients because of the lack of mammalian toxicity.
However, data submitted demonstrated low levels of mCry3A in corn
tissues with less than 2 micrograms mCry3A protein/gram dry weight in
kernals and less than 30 micrograms mCry3A protein/gram dry weight of
whole corn plant.
Since modified Cry3A is a protein, its potential allergenicity is
also considered as part of the toxicity assessment. Data considered as
part of the allergenicity assessment include that the modified Cry3A
protein came from Bacillus thuringiensis which is not a known
allergenic source, showed no sequence similarity to known allergens,
was readily degraded by pepsin, was inactivated by heat and was not
glycosylated when expressed in the plant. Therefore, there is a
reasonable certainty that modified Cry3A protein will not be an
allergen.
Neither available information concerning the dietary consumption
patterns of consumers (and major identifiable subgroups of consumers
[[Page 13272]]
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 mCry3A 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 in the crop.
The genetic material necessary for the production of the plant-
incorporated protectant active ingredients are the nucleic acids (DNA,
RNA) which comprise genetic material encoding these proteins and their
regulatory regions. The genetic material (DNA, RNA), necessary for
theproduction of mCry3A protein has been exempted under the blanket
exemption for all nucleic acids (40 CFR 174.475).
B. Infants and Children Risk Conclusions
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, also referred to as
margins of exposure (MOEs), 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 MOE 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 mCry3A
protein and the genetic material necessary for their production. Thus,
there are no threshold effects of concern to infants and children when
the mCry3A protein is used as a plant-incorporated protectant.
Accordingly, the Agency concludes that the additional MOE is not
necessary to protect infants and children, and that not adding any
additional MOE will be safe for infants and children.
C. Overall Safety Conclusion
There is a reasonable certainty that no harm will result from
aggregate exposure to the U.S. population, including infants and
children, to the mCry3A protein and the genetic material necessary for
its production. 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
above, no toxicity to mammals has been observed, nor any indication of
allergenicity potential for the plant-incorporated protectant.
VII. Other Considerations
A. Endocrine Disruptors
The pesticidal active ingredient is a protein, derived from sources
that are 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(s)
A method for extraction and ELISA analysis of mCry3A protein in
corn has been submitted and found acceptable by the Agency.
C. Codex Maximum Residue Level
No Codex maximum residue levels exist for the plant-incorporated
protectant Bacillus thuringiensis mCry3A protein and the genetic
material necessary for its production in corn.
VIII. Objections and Hearing Requests
Under section 408(g) of the FFDCA, as amended by the FQPA, any
person may file an objection to any aspect of this regulation and may
also request a hearing on those objections. The EPA procedural
regulations which govern the submission of objections and requests for
hearings appear in 40 CFR part 178. Although the procedures in those
regulations require some modification to reflect the amendments made to
the FFDCA by the FQPA, EPA will continue to use those procedures, with
appropriate adjustments, until the necessary modifications can be made.
The new section 408(g) of the FFDCA provides essentially the same
process for persons to ``object'' to a regulation for an exemption from
the requirement of a tolerance issued by EPA under new section 408(d),
as was provided in the old sections 408 and 409 of the FFDCA. However,
the period for filing objections is now 60 days, rather than 30 days.
A. What Do I Need to Do to File an Objection or Request a Hearing?
You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this unit
and in 40 CFR part 178. To ensure proper receipt by EPA, you must
identify docket ID number EPA-HQ-OPP-2006-0174 in the subject line on
the first page of your submission. All requests must be in writing, and
must be mailed or delivered to the Hearing Clerk on or before May 15,
2006.
1. Filing the request. Your objection must specify the specific
provisions in the regulation that you object to, and the grounds for
the objections (40 CFR 178.25). If a hearing is requested, the
objections must include a statement of the factual issues(s) on which a
hearing is requested, the requestor's contentions on such issues, and a
summary of any evidence relied upon by the objector (40 CFR 178.27).
Information submitted in connection with an objection or hearing
request may be claimed confidential by marking any part or all of that
information as CBI. Information so marked will not be disclosed except
in accordance with procedures set forth in 40 CFR part 2. A copy of the
information that does not contain CBI must be submitted for inclusion
in the public record. Information not marked confidential may be
disclosed publicly by EPA without prior notice.
Mail your written request to: Office of the Hearing Clerk (1900L),
Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. You may also deliver your request to the
Office of the Hearing Clerk in Suite 350, 1099 14th St., NW.,
Washington, DC 20005. The Office of the Hearing Clerk is open from 8
a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The
telephone number for the Office of the Hearing Clerk is (202) 564-6255.
2. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit VIII.A.,
you should also send a copy of your request to the PIRIB for its
inclusion in the official record that is described in ADDRESSES. Mail
your copies, identified by docket ID number EPA-HQ-OPP-2006-0174, to:
Public Information and Records Integrity Branch, Information Technology
and Resources Management Division (7502C), Office of Pesticide
Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. In person or by courier, bring a copy to the
location of the PIRIB described in ADDRESSES. You may also send an
electronic copy of your request via e-mail to: opp-docket@epa.gov.
Please use an ASCII file format and avoid the use of special characters
and any form of encryption. Copies of electronic objections and hearing
requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII
file format. Do not include any CBI in your electronic copy. You may
also submit an
[[Page 13273]]
electronic copy of your request at many Federal Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor would,
if established resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issues(s) in the manner sought
by the requestor would be adequate to justify the action requested (40
CFR 178.32).
IX. Statutory and Executive Order Reviews
This final rule establishes a temporary exemption from the
tolerance requirement under section 408(d) of the 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 rule has been exempted from review under
Executive Order 12866 due to its lack of significance, this rule is not
subject to Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355,
May 22, 2001). 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., or 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). 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);
or OMB review or any Agency action under Executive Order 13045,
entitled Protection of Children from Environmental Health Risks and
Safety Risks (62 FR 19885, April 23, 1997). 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). Since
tolerances and exemptions that are established on the basis of a
petition under section 408(d) of the FFDCA, such as the exemption 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. In addition, the Agency has determined that this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, entitled Federalism
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to
develop an accountable process to ensure ``meaningful and timely input
by State and local officials in the development of regulatory policies
that have federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. This action
does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency
has determined that this rule does not have any ``tribal implications''
as described in Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000). Executive Order 13175, requires EPA to develop an accountable
process to ensure ``meaningful and timely input by tribal officials in
the development of regulatory policies that have tribal implications.''
``Policies that have tribal implications'' is defined in the Executive
order to include regulations that have ``substantial direct effects on
one or more Indian tribes, on the relationship between the Federal
Government and the Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.''
This rule will not have substantial direct effects on tribal
governments, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this rule.
X. Congressional Review Act
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 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).

2. Section 174.456 is revised to read as follows:
Sec. 174.456 Bacillus thuringiensis modified Cry3A protein (mCry3A)
and the genetic material necessary for its production in corn.
Bacillus thuringiensis modified Cry3A protein (mCry3A) and the
genetic material necessary for its production in corn is temporarily
exempt from the requirement of a tolerance when used as plant-
incorporated protectant in the food and feed commodities of field corn,
sweet corn and popcorn. Genetic material necessary for its production
means the genetic material which comprise genetic material encoding the
mCry3A protein and its regulatory regions. Regulatory regions are the
genetic material, such as promoters, terminators, and enhancers, that
control the expression of the genetic material encoding the mCry3A
protein. This temporary exemption from the requirement of a tolerance
will permit
[[Page 13274]]
the use of the food commodities in this paragraph when treated in
accordance with the provisions of the experimental use permit 67979-
EUP-4 which is being issued under the Federal Insecticide, Fungicide,
and Rodenticide Act (FIFRA), as amended (7 U.S.C. 136). This temporary
exemption from the requirement of a tolerance expires and is revoked
October 15, 2007; however, if the experimental use permit is revoked,
or if any experience with or scientific data on this pesticide indicate
that the tolerance is not safe, this temporary exemption from the
requirement of a tolerance may be revoked at any time.
