Background and Statutory Findings In the Federal Register of December 17, 2003 (67 FR 70251) (FRL- 7336-4), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U.S.C. 346a, as amended by the FQPA (Public Law 104-170), announcing the filing of a pesticide petition (PP 3E6656) by Dow Chemical Company, Building 1803, Midland, Michigan 48674. The petition requested that 40 CFR 180.920 be amended by establishing an exemption from the requirement of a tolerance for residues of cis-isomer of 1-(3- chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride. That notice included a summary of the petition prepared by the petitioner. Dow Chemical Company requested the use of cis-isomer of 1-(3-chloroallyl)- 3,5,7-triaza-1-azoniaadamantane chloride as a preservative at 0.14% by weight or less in pesticide formulations. No comments were received in response to the notice of filing. Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish an exemption from the requirement for 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(c)(2)(A)(ii) of the 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 the 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....'' These provisions were added to the FFDCA by the Food Quality Protection Act (FQPA) of 1996. III. Risk Characterization and Conclusion. Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action and considered its validity, [[Page 45655]] completeness and reliability and the relationship of this information 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 nature of the toxic effects caused by cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1- azoniaadamantane chloride are discussed in this unit. EPA has sufficient data to assess the hazards of and make a determination on aggregate exposure for the chemical.The following provides a brief summary of the risk assessment and conclusions for the Agency's review of cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride. The full decision document for this action is available on EPA's Electronic Docket at http://www.regulations.gov/ under docket number EPA-HQ-OPP-2007-0220. A. Human Health The Agency reviewed the available information on cis-isomer of 1- (3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride submitted by the petitioner as well as additional information available to EPA and the data evaluated in the 1995 Dowicil[reg]CTAC RED. The toxicity database is sufficient for cis-isomer of 1-(3-chloroallyl)-3,5,7- triaza-1-azoniaadamantane chloride. In laboratory animal studies measuring acute toxicity, cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza- 1-azoniaadamantane chloride is slightly toxic in acute inhalation and oral toxicity studies. Dermal effects were observed in rabbits at close to the limit dose (no observed adverse effect level of 1,000 milligram/ kilogram/day (mg/kg/day)) in a subchronic study, and in a dermal acute toxicity study the LD50 was determined to be 923 mg/day. The chemical was mutagenic in the in vitro Chinese hamster ovary cell HGPRT (Hypoxanthine guanine phophoribosyl transferase)forward mutation assay with activation, but was nonmutagenic without activation. It was negative in two other mutagenicity studies. Developmental effects were observed at or above the level of maternal toxicity (optic malformations may be linked to genetic issues rather than exposure to the chemical). Chronic toxicity studies are not available, nevertheless, sufficient information is available in sub-chronic and developmental toxicity studies. B. Exposure Assessment The potential for exposure to residues of cis-isomer of 1-(3- chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride is adequately characterized based on the chemical's non-persistent nature and ready dissipation in the environment and the low use rate. Exposures from residues in food and drinking water are expected to be minimal. Residential exposure (inhalation and dermal) is also expected to be minimal from the use of the chemical in pesticides considering the low application rate. Residential exposures from non-pesticides uses are not anticipated to be of concern considering the low dermal toxicity findings. The Agency concludes dietary and residential exposures of concern are not anticipated from the inert ingredient use of cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride considering its non-persistent nature in the environment, low toxicity, and the limitations imposed on its proposed use under 40 CFR 180.920 as a preservative at 0.14% by weight (wt) or less of the pesticide formulation. C. Safety Factor for Infants and Children Section 408 of the FFDCA provides that EPA shall apply an additional tenfold margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. The toxicity database is sufficient for cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1- azoniaadamantane chloride and potential exposure is adequately characterized based on the low use rate. In terms of hazard, there are low concerns and no residual uncertainties regarding prenatal and/or postnatal toxicity. D. Cumulative Exposure Section 408(b)(2)(D)(v) of the FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, 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.'' Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1- azoniaadamantane chloride and any other substances, and the chemical does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1- azoniaadamantane chloride has a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's website at http://www.epa.gov/pesticides/cumulative . E. Other Considerations 1. Analytical methods. Adequate enforcement methodology is available to enforce the tolerance exemption 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; e-mail address: residuemethods@epa.gov. Residues are not expected because of the chemical's ready degradation in the environment and the low amount that will be permitted in the pesticide formulation (limited to 0.14% by weight (wt) or less). 2. International tolerances. The Agency is not aware of any country requiring a tolerance for cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza- 1-azoniaadamantane chloride (CAS Reg. No. 51229-78-8) nor have any CODEX Maximum Residue Levels (MRLs) been established for any food crops at this time. F. Determination of Safety and Conclusions Based on the information in this preamble, EPA concludes that there is a reasonable certainty of no harm to the general population, including infants and children, from aggregate exposure to residues of cis-isomer of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride. Accordingly, EPA finds that exempting cis-isomer of 1-(3- chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride from the requirement of a tolerance will be safe. EPA is establishing a tolerance exemption in 40 CFR 180.920 for cis-isomer of 1-(3- chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride when it is used as an inert ingredient as a preservative at 0.14% by weight or less in pesticide formulations. [[Page 45656]] IV. Statutory and Executive Order Reviews This final rule establishes a tolerance exemption under section 408(d) of FFDCA 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 rule has been exempted from review under Executive Order 12866, this rule is not subject to Executive Order 13211, 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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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 6, 2000) do not apply to this rule. In addition, This 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) (Public Law 104-4). 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), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). V. Congressional Review Act The Congressional Review Act, 5 U.S.C. 801 et seq., generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report to each House of the Congress and to the Comptroller General of the United States. 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 this final rule in the Federal Register. This final rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
