40 CFR Part 174
[EPA-HQ-OPP-2006-0784; FRL-8096-4]
Bacillus Thuringiensis Modified Cry3A Protein and the Genetic
Material Necessary for Its Production in Corn; Exemption from the
Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes a permanent exemption from the
requirement of a tolerance for residues of the 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. Syngenta Seeds, Inc.
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 an exemption from the requirement of a tolerance.
This regulation eliminates the need to establish a maximum permissible
level for residues of Bacillus thuringiensis modified Cry3A protein
(mCry3A) and the genetic material necessary for its production in corn.
DATES: This regulation is effective November 1, 2006. Objections and
requests for hearings must be received on or before January 2, 2007,
and must be filed in accordance with the instructions provided in 40
CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings
In the Federal Register of October 27, 2004 (69 FR 62688) (FRL-
7370-1), 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 4F6838) by Syngenta Seeds, Inc., P.O. Box 12257,
3054 Cornwallis Road, Research Triangle Park, NC 27709-2257. The
petition requested that 40 CFR part 174 be amended by establishing a
permanent exemption from the requirement of a tolerance for residues of
modified Cry3A protein (mCry3A) and the genetic material necessary for
its production in corn. 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 from the National Corn
Growers Association.
[[Page 64129]]
They supported the petition and requested EPA to quickly issue the
final rule.
On March 14-15, 2006, EPA held a FIFRA Scientific Advisory Panel
(SAP) meeting, at http://www.epa.gov/scipoly/sap/meetings/2006/index.htm#march
to address the scientific issues that arose during the
risk assessment of mCry3A. EPA asked the SAP to comment on the
equivalence of the mCry3A proteins from corn event MIR604 and from
recombinant E. coli - specifically the presence of two forms in the
bacterial-produced mCry3A protein and the differences in bioactivity in
the WCRM bioassay. The majority of the Panel concluded that the two
forms of the mCry3A are of relatively comparable biological activity
for the purposes of the human health assessments based on the amino
acid sequence identity, lack of glycosylation, and general stability.
EPA also asked the SAP to comment on EPA's conclusions regarding
the lack of mammalian toxicity and allergenicity of the mCry3A protein-
specifically the impact of the less potent mCry3A form on the results
of the acute oral toxicity tests and the usefulness of in vitro
digestibility studies and amino acid sequence homology analysis as part
of the risk assessment. Overall, the Panel was more concerned with the
quality of data, i.e. inadequately described methods and poor
reproduction of data images. The Panel specifically noted that the
amino acid sequence analysis to known toxins and allergens were missing
the following data: Specification of which version of NCBI database was
utilized; descriptions of parameters utilized; and dates accessed for
the BLAST search. EPA recognizes that these are important parameters to
include in a description of an amino acid analysis and is requiring
submission of additional information by Syngenta Seeds, Inc. in order
to confirm the method used. However, EPA maintains that the conclusions
of the amino acid sequence analysis are still valid for the purpose of
the risk assessment. EPA reached this decision based on the following:
(1) Lack of mammalian toxicity of mCry3A protein as shown by the acute
oral mouse study; (2) mCry3A protein is rapidly digested in SGF; (3)
mCry3A protein originates from a non-allergenic source; (4) lack of
sequence identity of mCry3A protein with eight contiguous amino acids
or more than 35% identity over 80 amino acids with known toxins or
allergens; and (5) mCry3A protein is not glycosylated when expressed in
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 mCry3A protein alone. 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 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 and known
toxic proteins available in public protein data bases. According to the
Codex Alimintarius guidelines, the assessment of potential toxicity
also includes stability to heat (FAO/WHO Standards Programme, 2001).
Further data demonstrate that mCry3A is inactivated against Western
corn rootworm, when heated to 95 [deg]C for 30 minutes.
Since mCry3A is a protein, allergenic sensitivities were
considered. Current scientific knowledge suggests that common food
allergens tend to be resistant to degradation by acid, and proteases;
may be glycosylated; and present at high concentrations 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 [mu]L
6 N HCl, and 2.7 mg/mL pepsin) resulting in 10 pepsin activity units/
microgram ([mu]g) protein (complies with year 2000 U.S. Pharmacopoeia
recommendations),
[[Page 64130]]
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, and is present in low levels in corn
tissue. Therefore, the potential for the mCry3A protein to be a food
allergen 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 present reasonable
certainty of 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). Moreover, mCry3A showed no
sequence similarity to any known toxin and was inactivated by heat
against Western corn rootworm. No further toxicity testing and residue
data were required because for microbial products, further toxicity
testing and residue data requirements 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).
Modified Cry3A 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 [mu]g mCry3A protein/gram dry weight in
kernals and less than 30 [mu]g 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, 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 the
production of mCry3A protein has been exempted under the blanket
exemption for all nucleic acids (40 CFR 174.475).
[[Page 64131]]
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. Statutory and Executive Order Reviews
This final rule establishes an exemption from the requirement of a
tolerance 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 from
the requirement of a 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. 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.
IX. 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
[[Page 64132]]
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).

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.
