ACTION: Final rule. AGENCY: SUMMARY: This regulation extends the temporary exemption from the requirement of a tolerance for residues of Bacillus thuringiensis Vip3Aa20 protein in corn when applied or 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 that the temporary tolerance exemption be extended. This regulation eliminates the need to establish a maximum permissible level for residues of the Bacillus thuringiensis Vip3Aa20 protein in corn when applied or used as a plantincorporated protectant on field corn, sweet corn, and popcorn. The temporary tolerance exemption expires on October 31, 2009. DATES: This regulation is effective December 5, 2007. Objections and requests for hearings must be received on or before February 4, 2008, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

Background and Statutory Findings In the Federal Register of August 8, 2007 (72 FR 44521) (FRL–8139–7), 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 petition (PP 7F7212) by Syngenta Seeds, Inc., 3054 Cornwallis Rd., P.O. Box 12257, Research Triangle Park, NC 27709. The petition requested VerDate Aug<31>2005 17:07 Dec 04, 2007 Jkt 214001 that 40 CFR 174.458 (now 40 CFR 174.528, see the Federal Register issue of April 25, 2007 (72 FR 20431) (FRL– 7742–2) be amended such that the temporary tolerance exemption for Bacillus thuringiensis Vip3Aa20 protein and the genetic material necessary for its production in corn when applied/ used as a plant-incorporated protectant on field corn, sweet corn, and popcorn expires on October 31, 2009. This notice included a summary of the petition prepared by Syngenta Seeds, Inc., the registrant. There were no comments received in response to the notice of filing. Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an exemption from the requirement for a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the exemption is ‘‘safe.’’ Section 408(c)(2)(A)(ii) of FFDCA defines ‘‘safe, ’’ to mean that ‘‘there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.’’ This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Pursuant to 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(c)(2)(B) of FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action PO 00000 Frm 00056 Fmt 4700 Sfmt 4700 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 a lack of mammalian toxicity at high levels of exposure to the pure (microbially expressed) Vip3Aa20 protein. These data demonstrate the safety of Vip3Aa20 at 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, the need for Tier II and III toxicity testing and residue data to verify the observed effects and clarify the source of these effects is triggered only by significant acute effects in studies such as the mouse oral toxicity study. In order to clarify the discussion that follows in the remainder of this final rule, it is necessary to distinguish the various Vip3A designations that are used. Vip3Aa20 is the designation applicable to Vip3A protein expressed in corn. Vip3Aa19 is the designation applicable to Vip3A protein expressed in cotton. Because the Agency has determined that both Vip3Aa19 and Vip3Aa20 are functionally equivalent, the Agency in amending this temporary tolerance exemption for Vip3Aa20 expressed in corn has relied on data and analysis specifically developed for Vip3Aa20, as well as on data and analysis specifically developed for Vip3Aa19. A separate temporary exemption from the requirement of tolerance already has been established for Vip3Aa19 as expressed in cotton (72 FR 40754; 40 CFR 174.501). An acute oral toxicity study was submitted for the Vip3Aa19 protein. Male and female mice (16 of each) were dosed with 3,675 milligrams/kilograms bodyweight (mg/kg bwt) of Vip3Aa19 protein. All mice survived the study, gained weight, had no test materialrelated clinical signs, and had no test material-related findings at necropsy. This acute oral toxicity data also supports the prediction that the Vip3Aa20 protein would be non-toxic to humans. When proteins are toxic, they are known to act via acute mechanisms and at very low-dose levels (Sjoblad, Roy D., et al. 1992). Therefore, since no effects E:\FR\FM\05DER1.SGM 05DER1 sroberts on PROD1PC70 with RULES Federal Register / Vol. 72, No. 233 / Wednesday, December 5, 2007 / Rules and Regulations were shown to be caused by the plantincorporated protectants, even at relatively high-dose levels, the Vip3Aa20 protein is not considered toxic. Amino acid sequence comparisons showed no similarity between the Vip3Aa20 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 Food and Agriculture Organization of the United Nations/World Health Organization Standards Programme, 2001. A heat lability study demonstrated that Vip3Aa19 is inactivated against fall army worm, when heated to 55 °C for 30 minutes. Since Vip3Aa20 is a protein, allergenic sensitivities were considered. Currently, no definitive tests exist for determining the allergenic potential of novel proteins. Therefore, EPA uses a weight of the evidence approach where the following factors are considered: source of the trait; amino acid sequence similarity with known allergens; prevalence in food; and biochemical properties of the protein, including in vitro digestibility in simulated gastric fluid, and glycosylation. Current scientific knowledge suggests that common food allergens tend to be resistant to degradation acid and proteases; may be glycosylated; and present at high concentrations in the food. Data have been submitted that demonstrate that the Vip3A from recombinant maize (LPPACHA–0199) and E. coli (VIP3A-0100) proteins are rapidly degraded by gastric fluid in vitro. (VIP3A–0100 refers to a microbially expressed Vip3A that has been shown to be the equivalent of the plant-expressed Vip3A protein.) In a solution of simulated gastric fluid (containing pepsin) and either 80 microLiter (µL) of LPPACHA–0199 or 320 µL of VIP3A–0100 test protein, both were shown to be susceptible to pepsin degradation. These data support the conclusion that Vip3A proteins expressed in transgenic plants will be readily digested as a conventional dietary protein under typical mammalian gastric conditions. Further data demonstrate that Vip3Aa20 is not glycoslylated and a comparison of amino acid sequences of known allergens uncovered no evidence of any homology with Vip3Aa20, even at the level of 8 contiguous amino acid residues. Preliminary data of the quantification of Vip3Aa20 protein in various maize tissues were also submitted. This data demonstrated that mean Vip3Aa20 concentrations in corn VerDate Aug<31>2005 17:07 Dec 04, 2007 Jkt 214001 kernels ranged from circa (ca). 24.6–40.3 microgram (µg) Vip3Aa20/gram (g) dry weight, representing ca. 0.003% of the total protein in grain (assuming that corn grain contains 10% total protein by weight). Therefore, Vip3Aa20 is present in low levels in corn tissue and the protein expression is much lower than the amounts of allergen protein found in commonly allergenic foods. In those foods, the allergens can be 10 to 50% of the total protein found. Therefore, the potential for the Vip3Aa20 protein to be a food allergen is minimal. As noted in grams/kilogram (gm/kg), toxic proteins typically act as acute toxins with low-dose levels. Therefore, since no effects were shown to be caused by this plant-incorporated protectant, even at relatively high-dose levels, the Vip3Aa20 protein is not considered toxic. 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 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. The amino acid homology assessment revealed no similarities to known aeroallergens, indicating that Vip3A has a low potential to be an inhalation allergen. It has been demonstrated that there is no evidence of occupationally related respiratory symptoms, based on a health survey on migrant workers after exposure to Bacillus thuringiensis pesticides (Berstein et al. 1999), which provides further evidence of the negligible respiratory risks of Bacillus thuringiensis plant-incorporated protectants. Exposure via residential or lawn use to infants and children is also not expected because the use sites for PO 00000 Frm 00057 Fmt 4700 Sfmt 4700 68527 the Vip3Aa20 protein are all agricultural for control of insects. Oral exposure, at very low levels may occur from ingestion of processed corn products and, theoretically, drinking water. However, oral toxicity testing done at a dose in excess of 3 grams/kilogram showed no adverse effects. Furthermore, the expected dietary exposure from both cotton and corn are several orders of magnitude lower than the amounts of Vip3Aa20 protein shown to have no toxicity. Therefore, even if negligible aggregate exposure should occur, the Agency concludes that such exposure would present no harm due to the lack of mammalian toxicity and the rapid digestibility demonstrated for the Vip3Aa20 proteins. 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 include 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, the Agency concludes that there are no cumulative effects arising from Vip3Aa20 protein residues in corn. 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 Vip3Aa20 protein include the characterization of the expressed Vip3Aa20 protein in corn, as well as the acute oral toxicity, heat stability, 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 Vip3A protein test material derived from microbial cultures (designated VIP3A–0100) was biochemically and functionally similar to the Vip3Aa20 protein expressed in corn. Microbially produced protein was chosen in order to obtain sufficient material for testing. The acute oral toxicity data submitted support the prediction that the Vip3Aa20 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- E:\FR\FM\05DER1.SGM 05DER1 sroberts on PROD1PC70 with RULES 68528 Federal Register / Vol. 72, No. 233 / Wednesday, December 5, 2007 / Rules and Regulations dose levels (Sjoblad, Roy D., et al. 1992). Since no effects were shown to be caused by Vip3Aa20 protein, even at relatively high-dose levels (3,675 mg Vip3Aa19/kg bwt), the Vip3Aa20 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. Moreover, Vip3Aa20 showed no sequence similarity to any known toxin. Protein residue chemistry data for Vip3Aa20 were not required for a human health effects assessment of the subject plant-incorporated protectant ingredients because of the lack of mammalian toxicity. However, preliminary data (that were submitted with administrative materials for an Experimental Use Permit (EUP) application for corn expressing the Vip3Aa20 protein) demonstrated low levels of Vip3Aa20 in corn tissues with less than 40 µg Vip3Aa20 protein/g dry weight in kernels and less than 75 µg Vip3Aa20 protein/g dry weight of whole corn plant. Since Vip3Aa20 is a protein, its potential allergenicity is also considered as part of the toxicity assessment. Information considered as part of the allergenicity assessment included data demonstrating that the Vip3Aa20 protein came from a 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 the Vip3Aa20 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 Vip3Aa20 protein, as well as the minimal potential to be a food allergen, demonstrate the safety of Vip3Aa20 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 Vip3Aa20 protein already are exempted VerDate Aug<31>2005 17:07 Dec 04, 2007 Jkt 214001 from the requirement of a tolerance under a blanket exemption for all nucleic acids (40 CFR 174.507). B. Infants and Children Risk Conclusions Section 408(b)(2)(C) of FFDCA 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 data base, 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 Vip3Aa20 protein and the genetic material necessary for its production in corn. Because there are no threshold effects of concern, the Agency has determined that the additional tenfold margin of safety is not necessary to protect infants and children. Further, the provisions of consumption patterns, special susceptibility, and cumulative effects do not apply. C. Overall Safety Conclusion There is a reasonable certainty that no harm will result to the U.S. population, including infants and children, from aggregate exposure to residues of the Vip3Aa20 protein and the genetic material necessary for its production in corn, when it is applied/used in accordance with good agricultural practices on field corn, sweet corn, and popcorn. 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 previously discussed, no toxicity to mammals has been observed, nor has there been any indication of allergenicity potential for this 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 plantincorporated protectant at this time. PO 00000 Frm 00058 Fmt 4700 Sfmt 4700 B. Analytical Method(s) A method for extraction and Enzyme Linked Immunosorbent (ELISA) Analysis of Vip3Aa20 protein in corn has been submitted and is under review by the Agency. C. Codex Maximum Residue Level No Codex maximum residue levels exist for the plant-incorporated protectant Bacillus thuringiensis Vip3Aa20 protein and the genetic material necessary for its production in corn. VIII. Statutory and Executive Order Reviews This final rule extends the exemption from the requirement of a tolerance 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 rule has been exempted from review under Executive Order 12866, 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) 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 E:\FR\FM\05DER1.SGM 05DER1 Federal Register / Vol. 72, No. 233 / Wednesday, December 5, 2007 / Rules and Regulations 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 6, 2000) do not apply to this rule. In addition, This 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). IX. 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).

Bacillus Thuringiensis Vip3Aa20 Protein and the Genetic Material
Necessary for its Production in Corn; Extension of Temporary Exemption
Vip3Aa20 protein in corn when applied or used as a plant-incorporated
protectant. Syngenta Seeds, Inc., submitted a petition to EPA under the
Quality Protection Act of 1996 (FQPA), requesting that the temporary
tolerance exemption be extended. This regulation eliminates the need to
establish a maximum permissible level for residues of the Bacillus
thuringiensis Vip3Aa20 protein in corn when applied or used as a plant-
incorporated protectant on field corn, sweet corn, and popcorn. The
temporary tolerance exemption expires on October 31, 2009.

7F7212) by Syngenta Seeds, Inc., 3054 Cornwallis Rd., P.O. Box 12257,
Research Triangle Park, NC 27709. The petition requested that 40 CFR

25, 2007 (72 FR 20431) (FRL-7742-2) be amended such that the temporary
tolerance exemption for Bacillus thuringiensis Vip3Aa20 protein and the
genetic material necessary for its production in corn when applied/used
as a plant-incorporated protectant on field corn, sweet corn, and
popcorn expires on October 31, 2009.
This notice included a summary of the petition prepared by Syngenta
Seeds, Inc., the registrant. There were no comments received in
``safe, '' to mean that ``there is a reasonable certainty that no harm
Consistent with section 408(c)(2)(B) of FFDCA, EPA has reviewed the
at high levels of exposure to the pure (microbially expressed) Vip3Aa20
protein. These data demonstrate the safety of Vip3Aa20 at 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, the
need for Tier II and III toxicity testing and residue data to verify
the observed effects and clarify the source of these effects is
triggered only by significant acute effects in studies such as the
mouse oral toxicity study.
In order to clarify the discussion that follows in the remainder of
this final rule, it is necessary to distinguish the various Vip3A
designations that are used. Vip3Aa20 is the designation applicable to
Vip3A protein expressed in corn. Vip3Aa19 is the designation applicable
to Vip3A protein expressed in cotton. Because the Agency has determined
that both Vip3Aa19 and Vip3Aa20 are functionally equivalent, the Agency
in amending this temporary tolerance exemption for Vip3Aa20 expressed
in corn has relied on data and analysis specifically developed for
Vip3Aa20, as well as on data and analysis specifically developed for
Vip3Aa19. A separate temporary exemption from the requirement of
tolerance already has been established for Vip3Aa19 as expressed in
cotton (72 FR 40754; 40 CFR 174.501).
This acute oral toxicity data also supports the prediction that the
Vip3Aa20 protein would be non-toxic to humans.
and at very low-dose levels (Sjoblad, Roy D., et al. 1992). Therefore,
since no effects
[[Page 68527]]
were shown to be caused by the plant-incorporated protectants, even at
relatively high-dose levels, the Vip3Aa20 protein is not considered
toxic. Amino acid sequence comparisons showed no similarity between the
Vip3Aa20 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 Food
and Agriculture Organization of the United Nations/World Health
Organization Standards Programme, 2001. A heat lability study
demonstrated that Vip3Aa19 is inactivated against fall army worm, when
heated to 55 [deg]C for 30 minutes.
Since Vip3Aa20 is a protein, allergenic sensitivities were
allergenic potential of novel proteins. Therefore, EPA uses a weight of
the evidence approach where the following factors are considered:
protein, including in vitro digestibility in simulated gastric fluid,
and glycosylation. Current scientific knowledge suggests that common
food allergens tend to be resistant to degradation acid and proteases;
may be glycosylated; and present at high concentrations in the food.
the plant-expressed Vip3A protein.) In a solution of simulated gastric
fluid (containing pepsin) and either 80 microLiter ([micro]L) of
LPPACHA-0199 or 320 [micro]L of VIP3A-0100 test protein, both were
shown to be susceptible to pepsin degradation. These data support the
conclusion that Vip3A proteins expressed in transgenic plants will be
readily digested as a conventional dietary protein under typical
mammalian gastric conditions. Further data demonstrate that Vip3Aa20 is
not glycoslylated and a comparison of amino acid sequences of known
allergens uncovered no evidence of any homology with Vip3Aa20, even at
the level of 8 contiguous amino acid residues. Preliminary data of the
quantification of Vip3Aa20 protein in various maize tissues were also
submitted. This data demonstrated that mean Vip3Aa20 concentrations in
corn kernels ranged from circa (ca). 24.6-40.3 microgram ([micro]g)
Vip3Aa20/gram (g) dry weight, representing ca. 0.003% of the total
protein in grain (assuming that corn grain contains 10% total protein
by weight). Therefore, Vip3Aa20 is present in low levels in corn tissue
and the protein expression is much lower than the amounts of allergen
protein found in commonly allergenic foods. In those foods, the
allergens can be 10 to 50% of the total protein found.
Therefore, the potential for the Vip3Aa20 protein to be a food
allergen is minimal. As noted in grams/kilogram (gm/kg), toxic proteins
typically act as acute toxins with low-dose levels. Therefore, since no
effects were shown to be caused by this plant-incorporated protectant,
even at relatively high-dose levels, the Vip3Aa20 protein is not
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. The amino acid homology
assessment revealed no similarities to known aeroallergens, indicating
that Vip3A has a low potential to be an inhalation allergen. It has
been demonstrated that there is no evidence of occupationally related
respiratory symptoms, based on a health survey on migrant workers after
exposure to Bacillus thuringiensis pesticides (Berstein et al. 1999),
which provides further evidence of the negligible respiratory risks of
Bacillus thuringiensis plant-incorporated protectants. Exposure via
residential or lawn use to infants and children is also not expected
because the use sites for the Vip3Aa20 protein are all agricultural for
control of insects. Oral exposure, at very low levels may occur from
ingestion of processed corn products and, theoretically, drinking
kilogram showed no adverse effects. Furthermore, the expected dietary
exposure from both cotton and corn are several orders of magnitude
lower than the amounts of Vip3Aa20 protein shown to have no toxicity.
Therefore, even if negligible aggregate exposure should occur, the
Agency concludes that such exposure would present no harm due to the
lack of mammalian toxicity and the rapid digestibility demonstrated for
the Vip3Aa20 proteins.

The acute oral toxicity data submitted support the prediction that

when proteins are toxic, they are known to act via acute mechanisms and

to be caused by Vip3Aa20 protein, even at relatively high-dose levels
(3,675 mg Vip3Aa19/kg bwt), the Vip3Aa20 protein is not considered
toxic. This is similar to the Agency position regarding toxicity and
was derived. Moreover, Vip3Aa20 showed no sequence similarity to any
Protein residue chemistry data for Vip3Aa20 were not required for a
human health effects assessment of the subject plant-incorporated
protectant ingredients because of the lack of mammalian toxicity.
However, preliminary data (that were submitted with administrative
materials for an Experimental Use Permit (EUP) application for corn
expressing the Vip3Aa20 protein) demonstrated low levels of Vip3Aa20 in
corn tissues with less than 40 [micro]g Vip3Aa20 protein/g dry weight
in kernels and less than 75 [mu]g Vip3Aa20 protein/g dry weight of
whole corn plant.
Since Vip3Aa20 is a protein, its potential allergenicity is also
that the Vip3Aa20 protein came from a Bacillus thuringiensis which is
that the Vip3Aa20 protein will not be an allergen.
exposure to the Vip3Aa20 protein, as well as the minimal potential to
be a food allergen, demonstrate the safety of Vip3Aa20 at levels well
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 Vip3Aa20 protein already are exempted from the
Vip3Aa20 protein and the genetic material necessary for its production
in corn. Because there are no threshold effects of concern, the Agency
has determined that the additional tenfold margin of safety is not
necessary to protect infants and children. Further, the provisions of
consumption patterns, special susceptibility, and cumulative effects do
exposure to residues of the Vip3Aa20 protein and the genetic material
necessary for its production in corn, when it is applied/used in
accordance with good agricultural practices on field corn, sweet corn,
and popcorn. 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 previously discussed, no
toxicity to mammals has been observed, nor has there been any
indication of allergenicity potential for this plant-incorporated
effects of the plant-incorporated protectant at this time.

No Codex maximum residue levels exist for the plant-incorporated

This final rule extends the exemption from the requirement of a
