Summary of Petitioned-For Tolerance In the Federal Register of September 22, 2021 (86 FR 52624) (FRL- 8792-03-OCSPP), 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 1E8926) by IR-4, North Carolina State University, 1730 Varsity Drive, Venture IV, Suite 210, Raleigh, NC 27606. The petition requested that 40 CFR 180.478 be amended by establishing tolerances for residues of the herbicide rimsulfuron (N-[[(4,6-dimethoxy-2- pyrimidinyl)amino]carbonyl]-3-(ethylsulfonyl)-2-pyridinesulfonamide), in or on pomegranate at 0.01 parts per million (ppm) and tropical and subtropical, small fruit, edible peel, subgroup 23A at 0.01 ppm. There were no comments received in response to the notice of filing. III. Aggregate Risk Assessment and Determination of Safety FFDCA section 408(b)(2)(A)(i) 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.'' FFDCA section 408(b)(2)(A)(ii) 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. FFDCA section 408(b)(2)(C) 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 rimsulfuron including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with rimsulfuron follows. In an effort to streamline its publications in the Federal Register, EPA is not reprinting sections that repeat what has been previously published for tolerance rulemaking of the same pesticide chemical. Where scientific information concerning a particular chemical remains unchanged, the content of those sections would not vary between tolerance rulemaking and republishing the same sections is unnecessary. EPA considers referral back to those sections as sufficient to provide an explanation of the information EPA considered in making its safety determination for the new rulemaking. EPA has previously published a tolerance rulemaking for rimsulfuron in which EPA concluded, based on the available information, that there is a reasonable certainty that no harm would result from aggregate exposure to rimsulfuron and established tolerances for residues of that chemical. EPA is incorporating previously published sections from this rulemaking as described further in this rulemaking, as they remain unchanged. Toxicological profile. For a discussion of the Toxicological Profile of rimsulfuron, see Unit III.A of the February 12, 2018, final rulemaking (83 FR 5942) (FRL-9972-36). Points of departure/Levels of concern. A summary of the toxicological endpoints for rimsulfuron used for human risk assessment is discussed in Unit III.B of the February 12, 2018, final rulemaking. Exposure assessment. Much of the exposure assessment remains the same although updates have occurred to accommodate the exposures from the petitioned-for tolerances. These updates are discussed in this section; for a description of the rest of the EPA approach to and assumptions for the exposure assessment, please reference Unit III.C of the February 12, 2018, final rulemaking. EPA's dietary exposure assessments have been updated to include the additional exposures from the new uses of rimsulfuron on pomegranate and tropical and subtropical, small fruit, edible peel, subgroup 23A. An unrefined chronic dietary (food and drinking water) exposure and risk assessment was conducted using the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCID) Version 4.02. This software incorporates 2005-2010 consumption data from the U.S. Department of Agriculture's (USDA's) National Health and Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA). The chronic assessment used tolerance level residues for all crops and assumed that 100% of the crops were treated with rimsulfuron. The Agency's default processing factors were used where available. An acute dietary exposure assessment was not conducted since there was no adverse effect observed for a single dose of rimsulfuron. Dietary exposure from drinking water. The new uses do not result in an increase in the estimated residue levels in drinking water, so EPA used the same estimated drinking water concentrations in the chronic dietary assessment as identified in Unit III.C of the February 12, 2018, rulemaking. From non-dietary exposure. There are no proposed residential uses at this time; however, there are existing residential uses on turf that have been previously assessed using current data and assumptions. For the residential assessment of the turf uses, EPA did not conduct a quantitative residential handler risk assessment. The end use label requires handlers to wear specific clothing (long-sleeve shirt and long pants) and chemical-resistant gloves, so EPA assumed the product is not for homeowner use. There is the potential for post-application dermal exposures; however, a residential post-application dermal exposure assessment was not conducted because no dermal hazard was identified in the rimsulfuron database. The quantifiable post-application residential risk estimates reflect incidental oral exposure to children 1 to less than 2 years old from hand-to-mouth exposure to turf treated with rimsulfuron. The margin of exposure (MOE) is 26,000, which is greater than the level of concern of 100 and is not of concern. [[Page 4734]] Cumulative effects from substances with a common mechanism of toxicity. In 2016, EPA's Office of Pesticide Programs released a guidance document entitled, Pesticide Cumulative Risk Assessment: Framework for Screening Analysis https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/pesticide-cumulative-risk-assessment-framework. The agency has utilized this framework for rimsulfuron and determined that although rimsulfuron shares some chemical and/or toxicological characteristics (e.g., chemical structure or apical endpoint) with other pesticides, the toxicological database does not support a testable hypothesis for a common mechanism of action. No further data are required to determine that no common mechanism of toxicity exists for rimsulfuron and other pesticides and no further cumulative evaluation is necessary for rimsulfuron. Safety factor for infants and children. EPA continues to conclude that there are reliable data to support the reduction of the Food Quality Protection Act (FQPA) safety factor (SF) from 10X to 1X for all risk scenarios. See Unit III.D. of the February 12, 2018, final rulemaking for a discussion of the Agency's rationale for that determination. Aggregate risks and Determination of safety. EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute population adjusted dose (aPAD) and the chronic population adjusted dose (cPAD). Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate points of departure to ensure that an adequate MOE exists. For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. An acute dietary exposure assessment was not conducted since there was no adverse effect observed for a single dose of rimsulfuron. Chronic dietary risks are below the Agency's level of concern of 100% of the cPAD; they are 1.8% of the cPAD for all infants (<1 year old), the population group receiving the greatest exposure. The short-term aggregate exposure assessment for children 1 to less than 2 years old includes dietary (food and drinking water) and incidental oral exposure from hand-to-mouth activities from post- application exposure to turf. The short-term aggregate risk estimate for children 1 to less than 2 years old is an MOE of 3,700, which is greater than the level of concern of 100 and is not of concern. Acute risks are not expected due to no adverse effect observed for a single dose of rimsulfuron; and chronic aggregate risks to adults and children are equivalent to the dietary (food and drinking water) risks for those respective assessments and are not of concern. Because there is no intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD, no further assessment of intermediate-term risk is necessary. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, rimsulfuron is not expected to pose a cancer risk to humans. Therefore, based on the risk assessments and information described above, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to rimsulfuron residues. More detailed information on this action can be found in the document ``Rimsulfuron. Human Health Risk Assessment in Support of a Petition for the Establishment of Permanent Tolerances on Pomegranate and Tropical and Subtropical, Small Fruit, Edible Peel, Subgroup 23A'' in docket ID No. EPA-HQ-OPP-2021- 0447. IV. Other Considerations A. Analytical Enforcement Methodology For a discussion of the available analytical enforcement method for various crops, see Unit IV.A of the February 12, 2018, rulemaking. 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). Codex has not established MRLs for residues of rimsulfuron in or on any commodity associated with this action. V. Conclusion Therefore, tolerances are established for residues of rimsulfuron (N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-3-(ethylsulfonyl)-2- pyridinesulfonamide), in or on pomegranate at 0.01 ppm and tropical and subtropical, small fruit, edible peel, subgroup 23A at 0.01 ppm. In addition, as a housekeeping measure, EPA is removing the tolerance for potato at 0.1 ppm, which expired on August 12, 2018, and has no effect at this time. 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 tolerances 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 [[Page 4735]] 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 (CRA) Pursuant to the CRA (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).
