II. Summary of Petitioned-For Tolerance

In the Federal Register of September 15, 2017 (82 FR 43354) (FRL-9965-43), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 7E8571) by Syngenta Crop Protection, LLC, P.O. Box 18300, Greensboro, NC 27419. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the herbicide diquat in or on pea and bean, dry and shelled, except soybean, subgroup 6C at 0.08 parts per million (ppm). In the Federal Register of May 7, 2018 (83 FR 20008) (FRL-9976-34), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing a correction to the pesticide petition (PP 7E8571) by Syngenta Crop Protection, LLC, P.O. Box 18300, Greensboro, NC 27419. The corrected petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the herbicide diquat in or on pea and bean, dry and shelled, except soybean, subgroup 6C at 0.9 parts per million (ppm). Both documents referenced a summary of the petition prepared by Syngenta, the registrant, 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 IV.C.Start Printed Page 67289

III. Aggregate Risk Assessment and Determination of Safety

Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(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. Section 408(b)(2)(C) of FFDCA requires 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. . . .”

Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for diquat including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with diquat follows.

EPA conducted a human health risk assessment to evaluate the safety of the requested tolerances. See “Diquat. Human Health Risk Assessment for the Establishment of a Tolerance without U.S. Registration for Residues in/on Crop Subgroup 6C Dried Shelled Pea and Bean (Except Soybean)” (July 21, 2020), which is available in the docket established by this action, which is described under ADDRESSES. Locate and click on the hyperlink for docket ID number EPA-HQ-OPP-2017-0291. In that document, EPA evaluated the available hazard and exposure data to conduct dietary, residential, and aggregate assessment to determine risk to human health and refers back to the discussions of the hazard profile, residue chemistry database, and residential exposures contained in the previous human health risk assessment conducted for registration review, “Diquat Dibromide: Draft Human Health Risk Assessment for Registration Review” (Sept. 17, 2015) (“Registration Review RA”), which can be found in the docket EPA-HQ-OPP-2009-0846 and is included in this docket. Based on the discussion in the Registration Review RA, the Agency has determined that there is reliable data to support the use of a 1X margin of safety for the protection of infants and children.

While the acute dietary assessment was unrefined, using tolerance-level residues and 100% crop treated (PCT), the chronic dietary assessment was more refined and used anticipated-residue levels from magnitude of residue studies for crops irrigated with water treated with diquat in conjunction with estimates of percentage of crops irrigated. Default processing factors were also used in both the acute and chronic dietary analyses and both analyses incorporated the Office of Water's Maximum Contaminant Level (0.02 ppm) as a worst-case drinking water estimate due to domestic uses of diquat. EPA's aggregate exposure assessment incorporated the total dietary exposure, as well as exposure from residential sources, which is not impacted by the tolerance without U.S. registrations on pea and bean, dry and shelled, except soybean, subgroup 6C and thus has not changed since the Registration Review RA.

Acute aggregate dietary risks (food and water) are below the Agency's level of concern of 100% of the acute population adjusted dose: 1.4% of the aPAD for children 1 to 2 years old, the population group receiving the greatest exposure. Chronic dietary risks are below the Agency's level of concern of 100% of the chronic population adjusted dose (cPAD): 41% of the cPAD for children 1 to 2 years old the population group receiving the greatest exposure. For the short-/intermediate-term aggregate risk assessment, potential residential exposures were combined with dietary exposures. For both adults and children 1 to <2, exposures from high-contact activities on outdoor treated turf resulted in the highest residential exposures for aggregate consideration. Short-/intermediate-term aggregate margins of exposure (MOEs) are greater than the LOC of 100 (2,010 for adults and 280 for children 1 to 2 years old) and are therefore not of concern. Due to the lack of carcinogenicity, the Agency concludes that exposure is not expected to pose a cancer risk to the U.S. population.

Therefore, based on the risk assessments and information described above, EPA concludes there is a reasonable certainty that no harm will result to the general population, or to infants and children, from aggregate exposure to diquat residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodology (analytical method number RAM 272/02 “The Determination of Residues of Paraquat and Diquat in crops and Soil—A High Performance Liquid Chromatographic Method”) is available to enforce the tolerance expression.

B. International Residue Limits

In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.

The Codex has established an MRL for diquat in or on dry pea (subgroup) at 0.9 ppm. This MRL is the same as the tolerance established for diquat in this decision. However, Codex has established MRLs for diquat in or on dry bean (subgroup) at 0.4 ppm. Canada has established MRLs for both dry pea and dry bean at 0.9 ppm.

C. Response to Comments

Two general comments were received on the notices of filing expressing general concern about the potential of pesticide residues in food, although none provided any substantive information to take into consideration in EPA's safety assessment. The FFDCA authorizes EPA to establish tolerances that permit certain levels of pesticide residues in or on food when the Agency can determine that such residues are safe. EPA has made that determination for the tolerances subject to this action; commenters provided no information relevant to that conclusion.

V. Conclusion

Therefore, tolerances are established for residues of diquat in or on pea and bean, dry and shelled, except soybean, subgroup 6C at 0.9 ppm and the tolerance expression is being updated.Start Printed Page 67290

Also, in accordance with EPA's policy to update its tolerance expressions where applicable, EPA is revising the tolerance expression to clarify that (1) as provided in FFDCA section 408(a)(3), the tolerance covers metabolites and degradates of diquat not specifically mentioned; and (2) compliance with the specified tolerance levels is to be determined by measuring only the specific compounds mentioned in the tolerance expression. EPA has determined that it is reasonable to make this change final without prior proposal and opportunity for comment because public comment is not necessary since the change is merely intended to clarify the existing tolerance expression and has no substantive effect on the tolerance.

VI. Statutory and Executive Order Reviews

This action establishes tolerances 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).

VII. 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).
