AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes an exemption from the requirement of a tolerance for residues of Pseudomonas chlororaphis IPD072Aa protein in or on maize (hereafter IPD072Aa protein) when used as a Plant-Incorporated Protectant (PIP) in or on the food and feed commodities of corn: corn, field; corn, sweet; and corn, pop. Pioneer Hi-Bred International, Inc., 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 IPD072Aa protein.

II. Background and Statutory Findings

In the Federal Register of April 15, 2020 (85 FR 20910) (FRL-10006-540), 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 9F8785) 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 IPD072Aa protein in corn. That document referenced a summary of the petition prepared by the petitioner Corteva Agriscience, 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 ( print page 68784) 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 IPD072Aa 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 “Human Health Risk Assessment and Review of Product Characterization of the Insecticidal Plant-Incorporated Protectants, Pseudomonas chlororaphis IPD072Aa protein and DvSSJ1 dsRNA Complementary to the DvSSJ1 Gene Sequence from Diabrotica virgifera virgifera, and the Genetic Material Necessary (vector PHP74643), for their Production in Event DP23211 Maize (OECD Unique ID DP-Ø23211-2), and Establishment of a Permanent Tolerance Exemption. Data were provided in support of a FIFRA Section 3 Seed Increase Registration.” (hereafter Human Health Risk Assessment). This document, as well as other relevant information, is available in the docket for this action EPA-HQ-OPP-2019-0627.

IPD072Aa is a modified protein derived from the bacterium Pseudomonas chlororaphis and is active against coleopteran pests of corn. The Agency used a “weight of evidence” approach and determined that, IPD072Aa protein represents a negligible risk to humans or livestock that consume IPD072Aa maize products. The most likely exposure to the IPD072Aa protein is dietary through consumption of food products made from corn containing the protein. Oral exposure from ingestion of drinking water is unlikely because the IPD072Aa protein is present at very low levels within the plant cells and the amounts likely to enter the water column from leaves, pollen or plant detritus are low. Additionally, proteases and nucleases found in water and the environment would likely degrade the biological material containing the active ingredients and treatment process for municipal water plants are likely to remove IPD072Aa residues. Although there may be dietary exposure to residues of IPD07Aa protein, such exposure presents no concern for adverse effects. Submitted data show that the IPD072Aa protein is not toxic via the oral route of exposure and bioinformatics analysis did not indicate a toxigenic potential in silico. Likewise, the potential for allergenicity is low because: (1) The bacterium source of IPD07Aa protein, Pseudomonas chlororaphis, is not considered to be a source of allergenic proteins; (2) bioinformatic analysis indicates no similarity between IPD072Aa protein and known allergens; (3) IPD072Aa protein degrades rapidly when exposed to simulated gastric fluid and completely digested in simulated intestinal fluid or exposed to heat via food cooking; and (4) IPD072Aa 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.

Non-dietary non-occupational or residential exposure via pulmonary or ocular exposure is not likely since IPD072Aa protein is contained within plant cells, and corn pollen is not respirable nor is it present in commercial corn products. Exposure via the skin is somewhat more likely via the contact with corn products which might have been processed in a way that disrupts cellular structure. However, naturally occurring proteases are likely to degrade proteins in contact with the skin and, as described above, the IPD072Aa protein has little or no potential toxicity or allergenicity. Thus, adverse effects are not expected due to non-occupational and residential exposure to IPD072Aa. 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 IPD072Aa protein has been identified as no toxicity or allergenicity has been shown for this protein in the submitted studies. Therefore, EPA has concluded that IPD072Aa 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 IPD072Aa 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 IPD072Aa protein. Therefore, an exemption from the requirement of a tolerance is established for residues of IPD072Aa 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 protocol was submitted for a lateral flow test strip kit to be used for the detection of IPD072Aa protein in corn grain samples. The submitted protocol adequately describes the methodology.

IV. Statutory and Executive Order Reviews

This action establishes a tolerance 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 ( print page 68785) 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).
