Bacillus Thuringiensis Vip3Aa19 Protein in Cotton; Extension of a Temporary Exemption From the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
SUMMARY: This regulation extends the temporary exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis Vip3Aa19 protein in cotton when applied or used as a plant-incorporated protectant (PIP). 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 the temporary tolerance exemption be extended. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis Vip3Aa19 protein in cotton when applied or used as a PIP on cotton. The temporary tolerance exemption expires on May 1, 2009.
DATES: This regulation is effective December 6, 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 FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 7F7216) by Syngenta Seeds, Inc., 3054 Cornwallis Rd., P.O. Box 12257, Research Triangle Park, NC 27709. The petition requested that 40 CFR 174.501 be amended such that the temporary exemption from the requirement of a tolerance for residues of Bacillus thuringiensis Vip3Aa19 insect control protein (vector pCOT1) when applied or used as a PIP on cotton expires on May 1, 2009. This notice included a summary of the petition prepared by the petitioner, Syngenta Seeds, Inc. 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.

Toxicological Profile
Consistent with section 408(b)(2)(D) of 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
[[Page 68746]]
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) Vip3Aa19 protein. These data demonstrate the safety of Vip3Aa19 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 PIP 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 previously submitted Vip3A studies and applications, the designation VIP3A or Vip3A was used to describe the Vip PIP protein and/or test material. In the final rule, it is necessary to distinguish the various Vip3A designations based on the Crickmore Bacillus thuringiensis Vip3A nomenclature (see http://www.lifesci.sussex.ac.uk/Home/Neil_Crickmore/Bt ). The original Vip3A toxin as expressed in
COT102 is now known as Vip3Aa19 toxin according to the Crickmore nomenclature designation. A temporary exemption from the requirement of tolerance already has been established for the Bacillus thuringiensis Vip3Aa19 protein in cotton (See the Federal Register issue of July 25, 2007 (72 FR 40752) (FRL-8134-3); 40 CFR 174.501 that expires May 1, 2008.
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 material-related clinical signs, and had no test material-related findings at necropsy. This acute oral toxicity data supports the prediction that the Vip3Aa19 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 were shown to be caused by the PIP, even at relatively high-dose levels, the Vip3Aa19 protein is not considered toxic. Amino acid sequence comparisons showed no similarity between the Vip3Aa19 protein and known toxic proteins available in public protein data bases. According to the Codex Alimintarius Commission (Codex) guidelines, the assessment of potential toxicity also includes stability to heat (Joint Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO) Food Standard Programme, Codex Alimentarius Commission, 2003\1\). A heat lability study demonstrated that Vip3Aa19 is inactivated against fall armyworm when heated to 55 [deg]C for 30 minutes.
\1\ Alinorm 03/34: Joint FAO/WHO Food Standard Programme, Codex Alimentarius Commission, Twenty-Fifth Session, Rome, Italy 30 June-5 July, 2003. Appendix III, Guideline for the conduct of food safety assessment of foods derived from recombinant-DNA plants and Appendix IV, Annex on the assessment of possible allergenicity. Rome, Codex Alimentarius Commission, 2003, p.p 47-60.
Since Vip3Aa19 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 (SGF), and glycosylation. This approach was described by the Codex guidelines for the conduct of food safety assessment of food derived from recombinant-DNA plants including the assessment of possible allergenicity in 2003 (Joint FAO/WHO Food Standard Programme, Codex Alimentarius Commission, 2003\1\).
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 SGF (containing pepsin) and either 80 microLiters ([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 Vip3Aa19 is not glycoslylated and a comparison of amino acid sequences of known allergens uncovered no evidence of any homology with Vip3Aa19, even at the level of eight contiguous amino acid residues. These data demonstrated that mean Vip3Aa19 concentration in cotton seed ranged from (circa). 2.51 to 3.23 micrograms ([micro]g) Vip3A/g dry weight. Vip3Aa19 was not detected in cotton fiber or nectar. Analysis of the refined oil and de-fatted meal by Enzyme-Linked Immunosorbent Assay (ELISA) detected Vip3Aa19 protein in COT102 meal, but not in oil. Therefore, based on the data provided for the specific Vip3Aa19 protein, one can conclude that the Vip3Aa19 protein is present in low levels in cotton seed and not detected in cotton fiber.
Therefore, the potential for the Vip3Aa19 protein to be a food allergen is minimal. As noted in Unit III., toxic proteins typically act as acute toxins with low dose levels. Therefore, since no effects were shown to be caused by this PIP, even at relatively high-dose levels, the Vip3Aa19 protein is not considered toxic.

Aggregate Exposures
In examining aggregate exposure, section 408 of FFDCA directs EPA to consider available information concerning exposures from the pesticide residue in food and all other non-occupational exposures, including drinking water from ground water or surface water and exposure through pesticide use in gardens, lawns, or buildings (residential and other indoor uses).
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 PIP chemical residue, and exposure from non-occupational sources. Exposure via the skin or inhalation is not likely since the PIP 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 PIPs. Exposure via residential or lawn use to infants and children is also not expected because the use sites for the Vip3Aa19 protein are all agricultural for control of insects. Oral exposure, at very low levels may
[[Page 68747]]
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 (gm/kg) showed no adverse effects. Furthermore, the expected dietary exposure from cotton is several orders of magnitude lower than the amounts of Vip3Aa19 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 Vip3Aa19 proteins.
-
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 Vip3Aa19 protein residues in cotton.

Toxicity and Allergenicity Conclusions
The data submitted and cited regarding potential health effects for the Vip3Aa19 protein include the characterization of the expressed Vip3Aa19 protein in cotton, 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 Vip3Aa19 protein expressed in cotton. Microbially produced protein was chosen in order to obtain sufficient material for testing.
The acute oral toxicity data submitted supports the prediction that the Vip3Aa19 protein would be non-toxic to humans. As mentioned in Unit III., when proteins are toxic, they are known to act via acute mechanisms and at very low-dose levels (Sjoblad, Roy D., et al. 1992). Since no effects were shown to be caused by Vip3Aa19 protein, even at relatively high dose levels (3,675 mg Vip3Aa19/kg bwt), the Vip3Aa19 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 PIP was derived. (See 40 CFR 158.740(b)(2)(i)). Moreover, Vip3Aa19 showed no sequence similarity to any known toxin.
Protein residue chemistry data for Vip3Aa19 were not required for a human health effects assessment of the subject PIP ingredients because of the lack of mammalian toxicity. Expression data demonstrated that mean Vip3Aa19 concentrations in cotton seed ranged from approximately 2.51 to 3.23 [micro]g Vip3Aa19/g dry weight. Vip3Aa19 was not detected in cotton fiber or nectar. Analysis of the refined oil and de-fatted meal by ELISA detected Vip3Aa19 protein in COT102 meal, but not in oil. Therefore, Vip3Aa19 is present in low levels in cotton seed and not detectable in cotton fiber.
Since Vip3Aa19 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 Vip3Aa19 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 Vip3Aa19 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 Vip3Aa19 protein, as well as the minimal potential to be a food allergen, demonstrate the safety of Vip3Aa19 at levels well above possible maximum exposure levels anticipated in the crop.
The genetic material necessary for the production of the PIP active ingredients are the nucleic acids Deoxyribonucleic acid, Ribonucleic acid (DNA, RNA) which comprise genetic material encoding these proteins and their regulatory regions. The genetic material DNA, RNA necessary for the production of Vip3Aa19 protein already are exempted from the requirement of a tolerance under a blanket exemption for all nucleic acids (40 CFR 174.507).
-
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 Vip3Aa19 protein and the genetic material necessary for its production in cotton. 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.
-
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 Vip3Aa19 protein and the genetic material necessary for its production in cotton, when it is applied or used in accordance with good agricultural practices. 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 PIP.

Other Considerations
-
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 PIP at this time.

Statutory and Executive Order Reviews
This final rule extends the temporary 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 do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply.
This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 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).

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).
