 AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of the spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8 in or on citrus when used as plant-incorporated-protectants in accordance with the terms of Experimental Use Permit (EUP) No. 88232-EUP-1. Southern Gardens Citrus Nursery, LLC, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the temporary tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8. The temporary tolerance exemption expires on May 31, 2021.

II. Background

In the Federal Register of May 6, 2015 (80 FR 25943) (FRL-9926-99), EPA previously established a temporary exemption from the requirement of a tolerance in 40 CFR part 174.535 for residues of spinach defensin proteins SoD2 and SoD7 in citrus. This exemption was established concurrently with an Experimental Use Permit (88232-EUP-1). Both the temporary tolerance exemption and EUP have expiration dates of April 18, 2018.

In the Federal Register of March 1, 2018 (83 FR 8827) (FRL-9973-57), 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 7G8630) by Southern Gardens Citrus Nursery, LLC, 1820 Country Road 833, Clewiston, FL 33440. The petition requested that the temporary tolerance exemption established in 40 CFR part 174.535 be amended and extended for residues of Spinach Defensin Proteins. Because the temporary tolerance exemption expired before we could complete this action, we are treating this as a petition to reestablish a temporary tolerance exemption. The petition referenced a summary of the petition prepared by the petitioner Southern Gardens Citrus Nursery, LLC, which is available in the docket, http://www.regulations.gov. Comments were received on the notice of filing. EPA's response to these comments is discussed in Unit III.C.

III. Final Rule

A. EPA's Safety Determination

Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an exemption Start Printed Page 24943from 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 has reviewed the available toxicity and exposure data on spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8 and considered its validity, completeness and reliability, and the relationship of this information to human risk. A full explanation of the data upon which EPA relied and its risk assessment based on that data can be found within the document entitled “Federal Food, Drug, and Cosmetic Act (FFDCA) Assessment of Defensin Proteins Derived from Spinach in Citrus Plants” dated April 27, 2018. This document, as well as other relevant information, is available in the docket for this action as described under ADDRESSES.

Based upon available data, EPA concludes that spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8, do not show evidence of toxicity. Moreover, there is no significant similarity between spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8 and known toxins and allergens. In addition, as discussed in the “Toxicological Profile” in the April 27, 2018 FFDCA Assessment document, the spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8 readily digest in simulated gastric fluids. Therefore, cumulative, chronic, and acute effects are unlikely. Furthermore, the source of the defensin proteins, spinach, has long been part of the human diet and there have been no findings that indicate toxicity or allergenicity of spinach proteins.

Given the lack of toxicity or allergenicity of the spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8, the Agency has not identified any toxicological endpoints for assessing risk. Due to the lack of any threshold effects, EPA has determined that the provision under FFDCA section 408(b)(2)(C) to retain a 10X safety factor for the protection of infants and children does not apply. Similarly, the lack of any toxic mode of action or toxic metabolites means that there is no available information concerning the cumulative effects of such residues and other substances that have a common mechanism of toxicity to be considered.

Oral exposure to spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8 may occur from ingestion of citrus products, such as fruit and juice. In addition, people have had a long history of consumption of spinach and will continue to be exposed to defensin proteins through consumption of spinach. Based on the lack of adverse effects and the rapid digestibility of the proteins, however, the Agency does not anticipate any risk from reasonably foreseeable levels of exposure. Since the plant-incorporated protectant is integrated into the plant's genome, the Agency has concluded, based upon previous science reviews, that the plant-incorporated protectant will not likely be found in ground or surface water and that residues in drinking water will be extremely low or non-existent. Non-occupational 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 levels of exposure. In any event, there are no non-dietary non-occupational uses of SoD2, SoD2*, SoD7, and SoD8 as they are only used in agricultural settings.

Based on its evaluation, EPA concludes that there is a reasonable certainty that no harm will result from aggregate exposure to the U.S. population, including infants and children, to the spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8. 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, there is no indication of toxicity or allergenicity potential for the plant-incorporated protectant. Therefore, a temporary exemption is established for residues of spinach defensin SoD2, SoD2*, SoD7, and SoD8 proteins in or on citrus when the proteins are used as plant-incorporated protectants in citrus plants. This exemption is being established concurrently with an extension to the Experimental Use Permit (EUP) No. 88232-EUP-1, and is therefore being established on a temporary basis. Both the EUP and temporary tolerance exemption will expire on May 31, 2021.

B. Analytical Enforcement Methodology

An analytical method is not required for enforcement purposes since the Agency is establishing a temporary exemption from the requirement of a tolerance without any numerical limitation.

C. Response to Comments

Two comments were received in response to the Notice of Filing (83 FR 8827). Neither of these anonymous comments were relevant to the proposed temporary tolerance exemption for spinach defensin proteins in citrus. One comment pertained to wind turbines and the other pertained to Chinese air quality.

IV. Statutory and Executive Order Reviews

This action establishes a temporary exemption from the requirement for 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 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 Start Printed Page 24944under FFDCA section 408(d), such as the temporary tolerance exemption 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).
