II. Summary of Petitioned-For Tolerance
In the Federal Register of August 1, 2014 (79 FR 44729) (FRL-9911-67), 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 4F8256) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research Triangle Park, NC 27709-3528. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the herbicide saflufenacil (2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2 H )-pyrimidinyl]-4-fluoro- N -[[methyl(1-methylethyl)amino]sulfonyl]benzamide) and its metabolites, N -[2-chloro-5-(2,6-dioxo-4-(trifluoromethyl)-3,6-dihydro-1(2 H )-pyrimidinyl)-4-fluorobenzoyl]- N' -isopropylsulfamide and N -[4-chloro-2-fluoro-5-({[(isopropylamino)sulfonyl]amino}carbonyl)phenyl]urea, calculated as the stoichiometric equivalent of saflufenacil, in or on alfalfa, forage at 0.075 parts per million (ppm) and alfalfa, hay at 0.10 ppm. That document referenced a summary of the petition prepared by BASF Corporation, the registrant, which is available in the docket, There were no comments received in response to the notice of filing.
Based upon review of the data supporting the petition, EPA agrees with the tolerance levels proposed by BASF Corporation for alfalfa commodities with the minor exception of a rounding adjustment for the alfalfa, forage tolerance from 0.075 ppm to 0.80 ppm.
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 saflufenacil including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with saflufenacil follows.
EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies 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.
The toxicology database for the saflufenacil is considered complete for the purpose of risk assessment. In the Federal Register of September 3, 2014 (79 FR 52215) (FRL-9912-91), EPA published a final rule establishing tolerances for residues of saflufenacil and its metabolites in or on barley, grass, olive, livestock, and wheat commodities based on EPA's conclusion that aggregate exposure to saflufenacil is safe for the general population, including infants and children. Since that rulemaking, the toxicity profile for saflufenacil has not changed. The requested tolerances will not result in residues on human food commodities, only animal feed. The available residue data submitted for use in alfalfa indicates that the dietary burden for livestock will not change from the current levels that were previously assessed for use in grass pastures. Therefore, the residues of saflufenicil on alfalfa from the proposed new use will not impact the existing human dietary and aggregate risk assessments for saflufenacil. For a detailed discussion of the aggregate risk assessments and determination of safety, as well as a summary of the toxicological endpoints used for human risk assessment, please refer to the final rules published in the Federal Register of February 21, 2014 (79 FR 9861) (FRL-9905-87) and September 3, 2014 (79 FR 52215) (FRL-9912-91). EPA relies upon those supporting risk assessments and the findings made in the Federal Register documents in support of this final rule.
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 saflufenacil residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (liquid chromatography/mass spectroscopy/mass spectroscopy (LC-MS/MS) (Method D0603/04)) is available to enforce the tolerance expression.
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 saflufenacil in or on alfalfa, forage or alfalfa, hay at this time.
C. Revisions to Petitioned-For Tolerances
EPA has modified the tolerance level proposed for alfalfa, forage, from 0.075 ppm to 0.08 ppm, which is the appropriate rounding class according to the tolerance calculation procedures of the Organization for Economic Co-operation and Development (OECD) that EPA utilizes.
V. Conclusion
Therefore, tolerances are established for residues of, saflufenacil and its metabolites, in or on alfalfa, forage at 0.08 ppm and alfalfa, hay at 0.10 ppm.
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).
