[EPA-HQ-OPP-2023-0022; FRL-12380-01-OCSPP]
Bacillus Thuringiensis Cry1Da2 Protein; Exemption From the Requirement of a Tolerance
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Final rule.
SUMMARY:
This regulation establishes an exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis Cry1Da2 protein in or on the food and feed commodities of corn: corn, field; corn, sweet; and corn, pop, when used as a plant-incorporated protectant (PIP). Pioneer Hi-Bred International, Inc., (Pioneer) submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Cry1Da2 protein.

II. Background and Statutory Findings
In the Federal Register of February 23, 2023 (88 FR 11401) (FRL-10579-01), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 0F9003) by Pioneer Hi-Bred International, Inc., 7100 NW 62nd Avenue, P.O. Box 1000, Johnston, Iowa 50131. The petition requested that 40 CFR part 174 be amended by establishing an exemption from the requirement of a tolerance for residues of Cry1Da2 protein. That document referenced a summary of the petition prepared by the petitioner Pioneer Hi-Bred International, Inc., which is available in the docket, https://www.regulations.gov . There were no comments received in response to the notice of filing.
III. Final Rule
A. EPA's Safety Determination
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 FFDCA 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 FFDCA 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, FFDCA section 408(b)(2)(D) 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 evaluated the available toxicity and exposure data on Cry1Da2 protein and considered its validity, completeness, and reliability, as well as 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. A summary of the data upon which EPA relied and its risk assessment based on those data can be found within the document entitled "Product Characterization Review and Human Health Risk Assessment of the Insecticidal Plant-Incorporated Protectant Active Ingredient, Bacillus thuringiensis Cry1Da2 and Plant-Incorporated Inert Ingredient DGT-28 EPSPS, and the Genetic Material Necessary (PHP88492) for their Production in Event DAS-1131-3 Maize, and Establishment of a Permanent Tolerance Exemption for Residues of these Proteins when used as a plant-incorporated protectant in corn" (hereafter Human Health Risk Assessment). This document, as well as other relevant information, is available in the docket for this action EPA-HQ-OPP-2023-0022.
The gene for the insecticidal protein Cry1Da2 was derived from the bacterium Bacillus thuringiensis (Bt) and contains sequences from Bt crystal toxins, Cry1Ab and Cry1D. The Cry1Da2 protein is intended to provide protection from certain lepidopteran pests of corn. In assessing the safety of the protein, the Agency used a "weight of evidence" approach and determined that, Cry1Da2 is not expected to pose any risk of toxicity to humans and the likelihood of the protein to be a food allergen is minimal. Submitted data show that the Cry1Da2 protein is not toxic via the oral route of exposure and a bioinformatics analysis did not indicate any homology to known toxins. Likewise, the potential for allergenicity is low because: (1) The bacterium source of Cry1Da2 protein, Bacillus thuringiensis, has a long history of safe use and is not considered to be a source of allergenic proteins; (2) bioinformatic analysis indicates no similarity between Cry1Da2 protein and known allergens; (3) Cry1Da2 protein degrades rapidly when exposed to simulated gastric fluid and completely digested within one minute when exposed to simulated intestinal fluid; (4) Cry1Da2 is inactivated when heated to high temperatures (=75 °C) that are typical of food cooking; and (5) Cry1Da2 protein is not glycosylated, which further reduces its allergenicity potential. Glycosylation is an enzymatic post-translational process in which carbohydrates (glycans) link to proteins, creating structures which could lead to an immune response in humans.
[top] The most likely exposure to the Cry1Da2 protein is dietary through consumption of food products made
Non-dietary, non-occupational or residential exposure via pulmonary, dermal, or ocular exposure is not likely since the Cry1Da2 protein is contained within plant cells and corn pollen is not respirable, which essentially eliminates these exposure routes or reduces them to negligible levels. Corn pollen is not considered respirable, as it consists of spherical particles ranging in size from 90 to 100 µm, whereas respirable particles are typically less than 10 µm. In the case of agricultural dusts derived from activities such as planting, cultivation, and harvest, these particles also tend to be of non-respirable sizes. Additionally, the low expression of Cry1Da2 in the grain of plants containing Cry1Da2 further supports the expectation that exposure via seed dust would be negligible. If exposure should occur, EPA concludes that such exposure would not be expected to present any risk due to the lack of toxicity. Thus, adverse effects are not expected due to non-occupational and residential exposure to Cry1Da2 protein. These findings are discussed in more detail in the Human Health Risk Assessment.
Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, 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." No risk of cumulative toxicity or effects from Cry1Da2 protein has been identified as no toxicity or allergenicity has been shown for this protein in the submitted studies. Therefore, EPA has concluded that Cry1Da2 protein does not have a common mechanism of toxicity with other substances.
Although FFDCA section 408(b)(2)(C) provides for an additional tenfold margin of safety for infants and children in the case of threshold effects, EPA has determined that there are no such effects due to the lack of toxicity of Cry1Da2 protein. As a result, an additional margin of safety for the protection of infants and children is unnecessary.
Based upon its evaluation described above and in the Human Health Risk Assessment, EPA concludes that 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 Cry1Da2 protein. Therefore, an exemption from the requirement of a tolerance is established for residues of Cry1Da2 protein in or on the food and feed commodities of corn: corn, field; corn, sweet; and corn, pop when used as a plant-incorporated protectant in corn.
B. Analytical Enforcement Methodology
EPA has determined that an analytical method is not required for enforcement purposes since the Agency is establishing an exemption from the requirement of a tolerance without any numerical limitation. Nonetheless, a validated enzyme linked immunosorbent assay (ELISA) was developed for detection of Cry1Da2 protein. This ELISA has been demonstrated to reliably detect the level of Cry1Da2 protein in the tissues of corn.
C. Conclusion
Therefore, an exemption from the requirement of a tolerance is established for residues of the Bacillus thuringiensis Cry1Da2 protein in or on the food and feed commodities of corn: corn, field; corn, sweet; and corn, pop when used as a plant-incorporated protectant (PIP) in corn.
IV. Statutory and Executive Order Reviews
This action establishes a tolerance exemption under FFDCA section 408(d) 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 action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled "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 action 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 FFDCA section 408(d), 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 action 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 FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or Tribal governments, on the relationship between the National Government and the States or Tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled "Federalism" (64 FR 43255, August 10, 1999), and Executive Order 13175, entitled "Consultation and Coordination with Indian Tribal Governments" (65 FR 67249, November 9, 2000), do not apply to this action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq. ).
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 (NTTAA) (15 U.S.C. 272 note).
V. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq. ), 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 the rule in the Federal Register . This action is not a "major rule" as defined by 5 U.S.C. 804(2).
