Background and Statutory Findings In the Federal Register of March 29, 2000 (65 FR 16594) (FRL-6498- 5), EPA issued a notice pursuant to section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a as amended by the Food Quality Protection Act of 1996 (FQPA) (Public Law 104-170) announcing the filing of a pesticide petition (PP) for tolerance by American Cyanamid Company, P.O. Box 400, Princeton, NJ 08543-0400. This notice included a summary of the petition prepared by American Cyanamid Company, the registrant. There were no comments received in response to the notice of filing. The petition was subsequently transferred to BASF Corporation, P.O. Box 400, Princeton, NJ 08543-0400. The petition requested that 40 CFR 180.508 be amended by establishing a tolerance for residues of the herbicide imazamox, (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H- imidazol-2-yl]-5-(methoxymethyl)-3-pyridinecarboxylic acid, in or on the raw agricultural commodities: vegetable, legume, group at 0.05 ppm; canola, seed at 0.05 ppm. Tolerances are established for the combined residues of the herbicide imazamox, and its metabolite, AC263284 (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H- imidazol-2-yl]-5-(hydroxymethyl)-3-pyridinecarboxylic acid in or on the following raw agricultural commodities wheat, grain, forage and hay at 0.3 ppm, wheat, straw at 0.2 ppm, wheat, bran at 1.0 ppm, wheat, shorts at 0.8 ppm, and wheat, germ at 0.6 ppm. Tolerances are established for the combined residues of the herbicide imazamox, and its metabolite, AC263284 (free and conjugated), and AC312622, (±)-2-[4,5- dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-3,5- pyridinecarboxylic acid in or on the following raw agricultural commodities: alfalfa, seed at 0.4 ppm, alfalfa, forage at 2.0 ppm and alfalfa, hay at 4.0 ppm respectively. Section 408(b)(2)(A)(i) of the 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) defines ``safe'' to mean that ``there is a reasonable [[Page 66774]] 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) 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....'' EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7). III. Aggregate Risk Assessment and Determination of Safety Consistent with 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, consistent with section 408(b)(2), for tolerances for residues of the herbicide imazamox, (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H- imidazol-2-yl]-5-(methoxymethyl)-3-pyridinecarboxylic acid, in or on the raw agricultural commodities: vegetable, legume, group at 0.05 ppm; canola, seed at 0.05 ppm. Tolerances are established for the combined residues of the herbicide imazamox, and its metabolite, AC263284 (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H- imidazol-2-yl]-5-(hydroxymethyl)-3-pyridinecarboxylic acid in or on the following raw agricultural commodities wheat, grain, forage and hay at 0.3 ppm, wheat, straw at 0.2 ppm, wheat, bran at 1.0 ppm, wheat, shorts at 0.8 ppm, and wheat, germ at 0.6 ppm. Tolerances are established for the combined residues of the herbicide imazamox, and its metabolite, AC263284 (free and conjugated), and AC312622, (±)-2-[4,5- dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-3,5- pyridinecarboxylic acid in or on the following raw agricultural commodities: alfalfa, seed at 0.4 ppm, alfalfa, forage at 2.0 ppm and alfalfa, hay at 4.0 ppm respectively. EPA's assessment of exposures and risks associated with establishing the tolerance follows. A. Toxicological Profile 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 nature of the toxic effects caused by imazamox are discussed in the following Table 1 as well as the no observed adverse effect level (NOAEL). There was no lowest observed adverse effect level (LOAEL) in any of the subchronic or chronic toxicity studies reviewed.

Exposure Assessment 1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.508) for the residues of imazamox, in or on the raw agricultural commodity soybeans. Due to low toxicity, it was determined that a dietary risk assessment of imazamox in food is not needed and, therefore, none was conducted. i. Acute exposure. Acute dietary risk assessments are performed for a food-use pesticide if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a one day or single exposure. No appropriate endpoint attributable to a single exposure (dose) was identified in the imazamox toxicity database including oral developmental toxicity studies in rats and rabbits. ii. Chronic exposure. There were no observed adverse effects at the highest dose tested (1,000 mg/kg/day or higher) in any of the subchronic or chronic toxicity tests conducted and the August 1998 OPPTS Series 870 Harmonized Test Guidelines for health effects recommend for subchronic and chronic testing the highest dose tested should not exceed 1,000 mg/kg/day using the procedures described for these studies, unless potential human exposure data indicate the need for higher doses. When imazamox was tested up to or above the limit dose, no significant adverse effects were observed. Therefore, it was determined that a chronic dietary risk assessment of imazamox in food is not needed and, therefore, none was conducted. 2. Dietary exposure from drinking water. The Agency uses the First Index Reservoir Screening Tool (FIRST) or the Pesticide Root Zone/ Exposure Analysis Modeling System (PRZM/EXAMS), to produce estimates of pesticide concentrations in an index reservoir. The screening concentration in ground water (SCI-GROW) model is used to predict pesticide concentrations in shallow groundwater. For a screening-level assessment for surface water EPA will use FIRST (a tier 1 model) before using PRZM/EXAMS (a tier 2 model). The FIRST model is a subset of the PRZM/EXAMS model that uses a specific high-end runoff scenario for pesticides. While both FIRST and PRZM/EXAMS incorporate an index reservoir environment, the PRZM/EXAMS model includes a percent crop area factor as an adjustment to account for the maximum percent crop coverage within a watershed or drainage basin. None of these models include consideration of the impact processing (mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The primary use of these models by the Agency at this stage is to provide a coarse screen for sorting out pesticides for which it is highly unlikely that drinking water concentrations would ever exceed human health levels of concern. Based on the FIRST and SCI-GROW models the estimated environmental concentrations (EECs) of imazamox for acute exposures are estimated to be 32 parts per billion (ppb) for surface water and 0.62 ppb for ground water. The EECs for chronic exposures are estimated to be 3.4 ppb for surface water and 0.62 ppb for ground water. These concentrations were compared to the lowest high dose tested in the toxicity studies (900 mg/kg) divided by an uncertainty factor of 100, i.e., 9 mg/kg. For chronic exposure in surface water, the EEC of 3.4 ppb is 5/10,000% of 9 mg/kg. For acute exposure in surface water, the EEC of 32 ppb is 4/ 1,000% of 9 mg/kg. For chronic and acute exposure in ground water, the EEC of 0.62 ppb is 7/10,000% of 9 mg/kg. Because the concentration of imazamox in drinking water are much smaller than 9 mg/kg, the contribution of consumption of imazamox via drinking water to total dietary consumption of imazamox (food plus water) is not significant. 3. From non-dietary exposure. The term ``residential exposure'' is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Imazamox is not registered for use on any sites that would result in residential exposure. 4. Cumulative exposure to substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) 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.'' EPA does not have, at this time, available data to determine whether imazamox has a common mechanism of toxicity with other substances or how to include this pesticide in a cumulative risk assessment. Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, imazamox 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 imazamox 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 the final rule for Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997). D. Safety Factor for Infants and Children 1. In general. FFDCA section 408 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. 2. Prenatal and postnatal sensitivity. No significant toxicity or pre- or post-natal toxicity was seen in any of the studies conducted with imazamox. 3. Conclusion. Due to its low toxicity a risk assessment using a safety factor approach was not conducted for imazamox. For similar reasons, it would not be appropriate to use an additional 10x safety factor to protect infants and children. E. Aggregate Risks and Determination of Safety 1. Acute risk. Since the acute toxicity is low (toxicity categories III and IV) for all tests conducted, the occurrence of an effect of concern as a result of a one day or single exposure is highly unlikely. It [[Page 66776]] was determined that contribution of additional dietary risk due to drinking water consumption is insignificant as described in section C. 2. above. 2. Chronic risk. There were no observed adverse effects at the highest dose tested (1,000 mg/kg/day or higher) in any of the subchronic or chronic toxicity tests conducted and the August 1998 OPPTS Series 870 Harmonized Test Guidelines for health effects recommend for subchronic and chronic testing the highest dose tested should not exceed 1000 mg/kg/day using the procedures described for these studies, unless potential human exposure data indicate the need for higher doses. When imazamox was tested up to or above the limit dose, no significant adverse effects were observed. Therefore, it was determined that a chronic dietary risk assessment of imazamox in food is not needed and, therefore, none was conducted. 3. Determination of safety. Based on the low toxicity of imazamox and the rationales described above, EPA concludes that there is a reasonable certainty that no harm will result to the general population, and to infants and children from aggregate exposure to imazamox residues. IV. Other Considerations A. Analytical Enforcement Methodology The method may be requested from Francis Griffith, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Road, Fort George G. Mead, Maryland, 20755-5350; telephone number: (410) 305-2905; e-mail address: griffith.francis@epa.gov. B. International Residue Limits There are no established or proposed Codex Maximum Residue Limits (MRLs) for imazamox. V. Conclusion Therefore, tolerances are established for residues of the herbicide imazamox, (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5- oxo-1H-imidazol-2-yl]-5-(methoxymethyl)-3-pyridinecarboxylic acid, in or on the raw agricultural commodities: vegetable, legume, group at 0.05 ppm; canola, seed at 0.05 ppm. Tolerances are established for the combined residues of the herbicide imazamox, and its metabolite, AC263284 (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5- oxo-1H-imidazol-2-yl]-5-(hydroxymethyl)-3-pyridinecarboxylic acid in or on the following raw agricultural commodities wheat, grain, forage and hay at 0.3 ppm, wheat, straw at 0.2 ppm, wheat, bran at 1.0 ppm, wheat, shorts at 0.8 ppm, and wheat, germ at 0.6 ppm. Tolerances are established for the combined residues of the herbicide imazamox, and its metabolite, AC263284 (free and conjugated), and AC312622, (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H- imidazol-2-yl]-3,5-pyridinecarboxylic acid in or on the following raw agricultural commodities: alfalfa, seed at 0.4 ppm, alfalfa, forage at 2.0 ppm and alfalfa, hay at 4.0 ppm respectively VI. Objections and Hearing Requests Under section 408(g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA of 1996, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) provides essentially the same process for persons to ``object'' to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d), as was provided in the old FFDCA sections 408 and 409. However, the period for filing objections is now 60 days, rather than 30 days. A. What Do I Need to Do to File an Objection or Request a Hearing? You must file your objection or request a hearing on this regulation in accordance with the instructions provided in this unit and in 40 CFR part 178. To ensure proper receipt by EPA, you must identify docket control number OPP-301205 in the subject line on the first page of your submission.

The Office of the Hearing Clerk is open from 8 a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The telephone number for the Office of the Hearing Clerk is (202) 260-4865. 2. Tolerance fee payment. If you file an objection or request a hearing, you must also pay the fee prescribed by 40 CFR 180.33(i) or request a waiver of that fee pursuant to 40 CFR 180.33(m). You must mail the fee to: EPA Headquarters Accounting Operations Branch, Office of Pesticide Programs, P.O. Box 360277M, Pittsburgh, PA 15251. Please identify the fee submission by labeling it ``Tolerance Petition Fees.'' EPA is authorized to waive any fee requirement ``when in the judgement of the Administrator such a waiver or refund is equitable and not contrary to the purpose of this subsection.'' For additional information regarding the waiver of these fees, you may contact James Tompkins by phone at (703) 305-5697, by e-mail at tompkins.jim@epa.gov, or by mailing a request for information to Mr. Tompkins at Registration Division (7505C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. If you would like to request a waiver of the tolerance objection fees, you must mail your request for such a waiver to: James Hollins, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. 3. Copies for the Docket. In addition to filing an objection or hearing request with the Hearing Clerk as described in Unit VI.A., you should also send a copy of your request to the PIRIB for its inclusion in the official record that is described in Unit I.B.2. Mail your copies, identified by docket control number OPP-301205, to: Public Information and Records Integrity Branch, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460.

Copies of electronic objections and hearing requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format. Do not include any CBI in your electronic copy. You may also submit an electronic copy of your request at many Federal Depository Libraries. B. When Will the Agency Grant a Request for a Hearing? A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32). VII. Regulatory Assessment Requirements This final rule establishes a tolerance 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 rule has been exempted from review under Executive Order 12866 due to its lack of significance, 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). 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., or 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). 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); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure ``meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' ``Policies that have federalism implications'' is defined in the Executive Order to include regulations that have ``substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.'' This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). For these same reasons, the Agency has determined that this rule does not have any ``tribal implications'' as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure ``meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.'' ``Policies that have tribal implications'' is defined in the Executive Order to include regulations that have ``substantial direct effects on one or more Indian tribes, on the relationship between the Federal government and the Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes.'' This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal government and Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule. VIII. Submission to Congress and the Comptroller General The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, 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).
