Final rule.


This regulation establishes tolerances for residues of sulfentrazone in or on succulent soybeans. Interregional Research Project Number 4 (IR-4) requested this tolerance under the Federal Food, Drug, and Cosmetic Act (FFDCA). In addition, this regulation corrects an incorrect commodity definition in the table. The term “Berry, low growing, group 13-07” is being revised to its correct term “Berry and small fruit, group 13-07.”


This regulation is effective September 28, 2012. Objections and requests for hearings must be received on or before November 27, 2012, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Summary of Petitioned-for Tolerance

In the Federal Register of July 25, 2012 (77 FR 43562) (FRL-9353-6), EPA issued a notice pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 2E8020) by IR-4, 500 College Road East, Suite 201W., Princeton, NJ 08540. The petition requested that 40 CFR 180.498 be amended by establishing tolerances for residues of the herbicide sulfentrazone (N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1 H-1,2,4-triazol-1-yl]phenyl]-methanesulfonamide) and its metabolites 3-hydroxymethylsulfentrazone (N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-hydroxymethyl-5-oxo-1 H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide) and 3-desmethyl sulfentrazone (N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-5-oxo-1 H-1,2,4-triazol-1-yl]phenyl] methanesulfonamide), in or on soybean, vegetable, succulent (Edamame) at 0.15 ppm. That notice referenced a summary of the petition prepared by FMC, the registrant, which is available in the docket, There were no comments received in response to the notice of filing.

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 sulfentrazone including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with sulfentrazone follows.

In the Federal Register of July 12, 2012 (77 FR 41081) (FRL-9353-8), EPA published a final rule establishing tolerances for residues of herbicide sulfentrazone in § 180.498(a)(2) in or on rhubarb; turnip roots; turnip tops; sunflower subgroup 20B; citrus fruit group 10-10; low growing berry group 13-07; tree nut group 14; pistachio; and § 180.498 (c) tolerances with regional registrations for wheat forage; wheat hay; wheat grain; wheat straw; and cowpea, succulent. The human health risk assessment used to support this final rule (“Sulfentrazone: Human-Health Risk Assessment for the Establishment of Sulfentrazone Tolerances in/on: Rhubarb, Turnip Roots and Tops, Sunflower Subgroup 20B, Succulent Cowpea, Succulent Lima Bean, Succulent Vegetable Soybean, Wheat (Spring), Citrus Fruit Group 10-10, Low-Growing Berry Group 13-07, Tree Nut Group 14, Pistachios, and Crop Group 18 Nongrass Animal Feeds”), assumed that sulfentrazone would be used on succulent soybeans. Therefore the aggregate risks for sulfentrazone for this action are not changed from those discussed in the July 12, 2012 Federal Register.

EPA concluded the following: That the acute dietary exposure from food and water to sulfentrazone will occupy 3.2% of the acute population adjusted dose (aPAD) for females 13-49 years old, the population group receiving the greatest exposure; that chronic exposure to sulfentrazone from food and water will utilize 4.2% of the chronic population adjusted dose (cPAD) for children 1-2 years old, the population group receiving the greatest exposure; and that the combined short-term food, water, and residential exposures result in an aggregate margin of exposure (MOE) of 280 for children 1-2 years old, and an aggregate risk index (ARI) of 3.9 for the general U.S. population and adult males. Because EPA's level of concern for sulfentrazone is an MOE of 100 or below and/or an ARI of 1 or below, this MOE and ARI are not of concern. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, sulfentrazone is not expected to pose a cancer risk to humans.

Therefore, EPA concluded that there is a reasonable certainty that no harm will result to the general population and to infants and children from aggregate exposure to sulfentrazone residues. Refer to the July 12, 2012 Federal Register document, available at, for a detailed discussion of the aggregate risk assessments and determination of safety. EPA relies upon those risk assessments and the findings made in the Federal Register document in support of this action.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodology (gas chromatography (GC)) is available to enforce the tolerance expression. The method has been forwarded for inclusion in the Pesticides Analytical Manual, Volume II. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; email address:

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 not established a MRL for sulfentrazone on succulent soybean.

V. Conclusion

Therefore, a tolerance is established for residues of sulfentrazone, (N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1 H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide) and its metabolites 3-hydroxymethylsulfentrazone (N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-hydroxymethyl-5-oxo-1 H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide) and 3-desmethyl sulfentrazone (N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-5-oxo-1 H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide), in § 180.498(a)(2) in or on vegetable, soybean, succulent at 0.15 ppm.

Also, EPA is amending the table in § 180.498(a)(2) to correct the description therein of Crop Group 13-07. Under EPA crop group regulations, Crop Group 13-07 is designated as the “Berry and Small Fruit Crop Group,” 40 CFR 180.41(c)(18). Consistent with this regulation, the petitioner requested the “berry and small fruit group 13-07” and provided the appropriate residue field trial data to support a tolerance on this group. EPA published appropriate notice of this request in the Federal Register, correctly describing the requested tolerance as being for the “berry and small fruit group 13-07,” in the Federal Register of July 6, 2011 (76 FR 39358) (FRL-8875-6). EPA also correctly identified in the final rule that petitioners had requested a “berry and small fruit group 13-07” and tolerance and EPA disclaimed any intent to modify this proposed tolerance, (77 FR 41082, 41086). Nonetheless, EPA mistakenly directed that paragraph (a)(2) be amended to establish a tolerance for “low growing berry group 13-07.” EPA is amending paragraph (a)(2) to revise “low growing berry group 13-07” with the correct regulatory term, “berry and small fruit group 13-07,” consistent with the petition's request and the Federal Register notice of the petition and EPA's disposition of the petition in the final rule published in the Federal Register of July 12, 2012.

VI. Statutory and Executive Order Reviews

This final rule 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 final rule has been exempted from review under Executive Order 12866, this final rule 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 final rule 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 final rule 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 final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (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 of 1995 (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).
