Petition for Tolerance In the Federal Register of August 13, 2008 (73 FR 47186) (FRL–8375–8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 8E7347) by IR-4, Rutgers, The State University of New Jersey, 500 College Road East, Suite 201 W., Princeton, NJ 08540. The petition requested that 40 CFR 180.593 be amended by establishing tolerances for residues of the insecticide etoxazole, 2(2,6-difluorophenyl)-4-[4-(1,1dimethylethyl)-2-ethoxyphenyl]-4,5- VerDate Nov<24>2008 16:09 May 26, 2009 Jkt 217001 dihydrooxazole, in or on fruit, stone, group 12, except plum at 1.0 parts per million (ppm); plum at 0.12 ppm; plum, prune, dried at 0.4 ppm; cucumber at 0.02 ppm; tomato at 0.25; spearmint, tops at 10 ppm; peppermint, tops at 10 ppm; peppermint, oil at 20 ppm; and spearmint, oil at 20 ppm. The petition additionally requested to delete the tolerance for residues of etoxazole in or on the food commodity cherry at 1.0 ppm. That notice referenced a summary of the petition prepared on behalf of IR4 by Valent U.S.A. Corporation, the registrant, which is available to the public in the docket, https:// www.regulations.gov. Comments were received on the notice of filing. EPA’s response to these comments is discussed in Unit IV.C. Based upon review of the data supporting the petition, EPA has revised the proposed tolerance levels for plum; plum, prune, dried; and tomato. The reason for these changes is explained in Unit IV.D. 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 section 408(b)(2)(D) of FFDCA, and the factors specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for tolerances for residues of etoxazole on fruit, stone, group 12, except plum at 1.0 ppm; plum at 0.15 ppm; plum, prune, dried at 0.30 ppm; cucumber at 0.02 ppm; tomato at 0.20; spearmint, tops at 10 ppm; peppermint, tops at 10 ppm; PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 25157 peppermint, oil at 20 ppm; and spearmint, oil at 20 ppm. EPA’s assessment of exposures and risks associated with establishing tolerances 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 existing etoxazole data indicate that it possess low acute toxicity via all routes of exposure. It is not an eye or dermal irritant or a dermal sensitizer. No toxicity was seen at the limit dose in a 28–day dermal toxicity study in rats. The liver is the main target organ in mice, rats and dogs. In a 90–day toxicity study in dogs, increased liver weights and centrilobular hepatocellular swelling in the liver were observed. Similar effects were observed in a chronic toxicity study in dogs at similar doses, indicating that systemic effects (mainly liver effects) occur at similar dose levels following short- through long-term exposure without increasing in severity. In a 90–day toxicity study in mice, hepatotoxicity (increased relative liver weight, liver enlargement, and centrilobular hepatocellular swelling) was observed at high doses. Similar effects were observed at the high dose in a mouse carcinogenicity study. Subchronic and chronic toxicity studies in rats produced similar effects (increased liver weights, centrilobular hepatocellular swelling, etc.) to those seen in mice and dogs. In addition, slight increases in thyroid weights and incisors were observed in subchronic and chronic toxicity studies in rats at high doses and at terminal stages of the study. Toxicity was not observed at the highest dose tested (HDT) in another carcinogenicity study in mice. There is no evidence of immunotoxicity or neurotoxicity in any of the submitted studies. Two studies in mice showed no evidence of carcinogenicity up to the HDT. In a rat carcinogenicity study, which was deemed unacceptable due to inadequate dosing, benign interstitial cell tumors (testis) and pancreas benign islet cell adenomas were observed (in females) at the high dose. These effects were not observed in an acceptable carcinogenicity study in rats at higher doses. In special mechanistic male rat studies there were no observable E:\FR\FM\27MYR1.SGM 27MYR1 25158 Federal Register / Vol. 74, No. 100 / Wednesday, May 27, 2009 / Rules and Regulations PWALKER on PROD1PC71 with RULES changes in serum hormone levels (estradiol, luteinizing hormone (LH), prolactin and testosterone) or reproductive effects (interstitial cell proliferation or spermatogenesis) noted. EPA classified etoxazole as ‘‘not likely to be carcinogenic to humans.’’ Etoxazole is not mutagenic. The toxicology data for etoxazole provides no indication of increased susceptibility, as compared to adults, of rat and rabbit fetuses to in utero exposure in developmental studies. The rabbit developmental toxicity study included maternal toxic effects (liver enlargement, decreased weight gain, and decreased food consumption) at the same dose as developmental effects (increased incidences of 27 presacral vertebrae and 27 presacral vertebrae with 13th ribs). In the two-generation reproduction study conducted with rats, offspring toxicity was more severe (pup mortality) than parental toxicity (increased liver and adrenal weights) at the same dose, indicating increased qualitative susceptibility. Specific information on the studies received and the nature of the adverse effects caused by etoxazole as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studiescan be found at https:// www.regulations.gov in document ‘‘Etoxazole; Human Health Risk Assessment for Proposed Uses on Stone Fruits, Cucumber, Tomato, and Mint,’’ pages 29-31 in docket ID number EPA– HQ–OPP–2008–0554. B. Toxicological Endpoints For hazards that have a threshold below which there is no appreciable risk, a toxicological point of departure (POD) is identified as the basis for derivation of reference values for risk assessment. The POD may be defined as the highest dose at which no adverse effects are observed (the NOAEL) in the toxicology study identified as appropriate for use in risk assessment. However, if a NOAEL cannot be determined, the lowest dose at which adverse effects of concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach is sometimes used for risk assessment. Uncertainty/safety factors (UFs) are used in conjunction with the POD to take into account uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. Safety is assessed for acute and chronic dietary risks by comparing aggregate food and water exposure to the pesticide to the acute population VerDate Nov<24>2008 16:09 May 26, 2009 Jkt 217001 adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD are calculated by dividing the POD by all applicable UFs. Aggregate short-, intermediate-, and chronic-term risks are evaluated by comparing food, water, and residential exposure to the POD to ensure that the margin of exposure (MOE) called for by the product of all applicable UFs is not exceeded. This latter value is referred to as the Level of Concern (LOC). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect greater than that expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see https://www.epa.gov/ pesticides/factsheets/riskassess.htm. A summary of the toxicological endpoints for etoxazole used for human risk assessment can be found at https:// www.regulations.gov in document ‘‘Etoxazole; Human Health Risk Assessment for Proposed Uses on Stone Fruits, Cucumber, Tomato, and Mint,’’ page 15 in docket ID number EPA–HQ– OPP–2008–0554. C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to etoxazole, EPA considered exposure under the petitioned-for tolerances as well as all existing etoxazole tolerances in (40 CFR 180.593). EPA assessed dietary exposures from etoxazole in food as follows: i. Acute exposure. Quantitative acute dietary exposure and 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 1–day or single exposure. No such effects were identified in the toxicological studies for etoxazole; therefore, a quantitative acute dietary exposure assessment is unnecessary. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 1994–1996 and 1998 CSFII. As to residue levels in food, EPA used tolerance-level residues and empirically determined (when available) or DEEM default processing factors. Additionally, EPA assumed 100 percent crop treated (PCT) for all commodities covered by proposed or existing tolerances. iii. Cancer. Two mouse studies showed no evidence of carcinogenicity PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 at the high dose. While benign interstitial cell tumors in the testis and pancreas benign islet cell adenomas were observed in an unacceptable rat carcinogenicity study, these effects were not seen in a repeat study at higher doses. Furthermore, special mechanistic male rat studies resulted in no observable changes in serum hormone levels (estradiol, luteinizing hormone, prolactin and testosterone) or reproductive effects (interstitial cell proliferation or spermatogenesis). EPA determined that cancer risk concerns due to long-term consumption of etoxazole residues are adequately addressed by the chronic dietary exposure analysis; therefore, etoxazole was classified as ‘‘not likely to be carcinogenic to humans,’’ and a quantitative exposure assessment to evaluate cancer risk is unnecessary. iv. Anticipated residue and PCT information. EPA did not use anticipated residue or PCT information in the dietary assessment for etoxazole. Tolerance level residues and 100 PCT were assumed for all food commodities. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for etoxazole in drinking water. These simulation models take into account data on the physical, chemical, and fate/ transport characteristics of etoxazole. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www.epa.gov/oppefed1/models/ water/index.htm. Based on the First Index Reservoir Screening Tool (FIRST) model for surface water, and Screening Concentration in Ground Water (SCIGROW) model for ground water, the estimated drinking water concentrations (EDWCs) of etoxazole and its major metabolites (R-8 and R-13) for surface water are estimated to be 15.73 parts per billion (ppb) for acute exposures and 4.761 ppb for chronic exposures. For ground water, the estimated drinking water concentration is estimated to be 0.746 ppb. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For chronic dietary risk assessment, the water concentration of value 4.761 ppb was used to assess the contribution to drinking water. 3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Etoxazole E:\FR\FM\27MYR1.SGM 27MYR1 Federal Register / Vol. 74, No. 100 / Wednesday, May 27, 2009 / Rules and Regulations is not registered for any specific use patterns that would result in residential exposure. 4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of 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.’’ EPA has not found etoxazole to share a common mechanism of toxicity with any other substances, and etoxazole does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that etoxazole does not have 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 https:// www.epa.gov/pesticides/cumulative. PWALKER on PROD1PC71 with RULES D. Safety Factor for Infants and Children 1. In general. Section 408(b)(2)(c) of FFDCA provides that EPA shall apply an additional tenfold (10X) 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 based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA safety factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. 2. Prenatal and postnatal sensitivity. The toxicology data for etoxazole provides no indication of increased susceptibility, as compared to adults, of rat and rabbit fetuses to in utero exposure in developmental studies. In a rat reproduction study, offspring toxicity was more severe (pup mortality) than parental toxicity (increased liver and adrenal weights) at the same dose; thereby indicating increased qualitative susceptibility. Based on the above concerns, a Degree of Concern Analysis was performed by EPA, which concluded that concern is low since: i. The effects in pups are wellcharacterized with a clear NOAEL; VerDate Nov<24>2008 16:09 May 26, 2009 Jkt 217001 ii. The pup effects occur at the same dose as parental toxicity; and iii. The doses selected for various risk assessment scenarios are lower than the doses that caused offspring toxicity. 3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1X. That decision is based on the following findings: i. The toxicity database for etoxazole is complete except for acute and subchronic neurotoxicity and immunotoxicity studies. Recent changes to 40 CFR 180.158 make acute and subchronic neurotoxicity testing (OPPTS Guideline 870.6200), and immunotoxicity testing (OPPTS Guideline 870.7800) required for pesticide registration. Because these testing requirements went into effect shortly before the tolerance petition was submitted, these studies are not yet available for etoxazole. However, the available data for etoxazole do not show potential for immunotoxicity. Further, there is no evidence of neurotoxicity in any study in the toxicity database for etoxazole. Therefore, EPA does not believe that conducting neurotoxicity and immunotoxicity studies will result in a NOAEL lower than the NOAEL of 4.62 milligrams/kilograms/day already established for etoxazole. Consequently, an additional database uncertainty factor does not need to be applied. ii. There is no indication that etoxazole is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional Uncertainity Factors (UFs) to account for neurotoxicity. iii. Although there is qualitative evidence of increased susceptibility of offspring (pup mortality) compared to less severe parental effects (increased liver and adrenal weights) at the same dose in the rat multi–generation reproduction study, the Agency did not identify any residual uncertainties after establishing toxicity endpoints and traditional UFs (10X for interspecies variation and 10X for intraspecies variation) to be used in the risk assessment. Therefore, there are no residual concerns regarding developmental effects in the young. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to etoxazole in drinking water. These assessments will not underestimate the exposure and risks posed by etoxazole. PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 25159 E. Aggregate Risks and Determination of Safety EPA determines whether acute and chronic pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and cPAD. The aPAD and cPAD represent the highest safe exposures, taking into account all appropriate SFs. EPA calculates the aPAD and cPAD by dividing the POD by all applicable UFs. For linear cancer risks, EPA calculates the probability of additional cancer cases given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the POD to ensure that the MOE called for by the product of all applicable UFs is not exceeded. 1. Acute risk. An acute aggregate risk assessment takes into account exposure estimates from acute dietary consumption of food and drinking water. No adverse effect resulting from a single-oral exposure was identified and no acute dietary endpoint was selected. Therefore, etoxazole is not expected to pose an acute risk. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to etoxazole from food and water will utilize 10% of the cPAD for children 1-2 years old, the population group receiving the greatest exposure. There are no residential uses for etoxazole to consider. 3. Short-, and intermediate-term risk. Short-, and intermediate-term aggregate exposure takes into account short-, and intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Etoxazole is not registered for any use patterns that would result in residential exposure. Therefore, the short-, and intermediate-term aggregate risk is the sum of the risk from exposure to etoxazole through food and water and will not be greater than the chronic aggregate risk. 4. Aggregate cancer risk for U.S. population. As discussed in Unit III.C.1.iii., EPA has classified etoxazole as ‘‘not likely to be carcinogenic to humans,’’ and it is not expected to pose a cancer risk to humans. 5. Determination of safety. Based on these risk assessments, 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 etoxazole residues.

Analytical Enforcement Methodology Adequate enforcement methodologies (gas chromatography/nitrogenphosphorus detection (GC/NPD) and gas chromatography/mass selective detection (GC/MSD) methods) are available to enforce the tolerance expression. The methods 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. B. International Residue Limits Currently, there are no Codex, Canadian, or Mexican maximum residue limits (MRLs) established for residues of etoxazole in or on the subject commodities. C. Response to Comments EPA received one comment to the Notice of Filing that made a general objection to the presence of any pesticide residues on crops and stated that EPA should set no pesticide tolerance greater than zero. The Agency understands the commenter’s concerns and recognizes that some individuals believe that pesticides should be banned completely. However, the existing legal framework provided by section 408 of FFDCA states that tolerances greater than zero may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. This citizen’s comment appears to be directed at the underlying statute and not EPA’s implementation of it; the citizen has made no contention that EPA has acted in violation of the statutory framework. PWALKER on PROD1PC71 with RULES D. Revisions to Petitioned-For Tolerances Based upon review of the data supporting the petition, EPA revised tolerances for certain proposed commodities, as follows: Plum from 0.12 ppm to 0.15 ppm; plum, prune, dried from 0.40 ppm to 0.30 ppm; and tomato from 0.25 ppm to 0.20 ppm. EPA revised the tolerance levels based on analysis of the residue field trial data using the Agency’s Tolerance Spreadsheet in accordance with the Agency’s Guidance for Setting Pesticide Tolerances Based on Field Trial Data. V. Conclusion Therefore, tolerances are established for residues of etoxazole, 2-(2,6difluorophenyl)-4-[4-(1,1dimethylethyl)-2-ethoxyphenyl]-4,5- VerDate Nov<24>2008 16:09 May 26, 2009 Jkt 217001 dihydrooxazole, in or on fruit, stone, group 12, except plum at 1.0 ppm; plum at 0.15 ppm; plum, prune, dried at 0.30 ppm; cucumber at 0.02 ppm; tomato at 0.20 ppm; spearmint, tops at 10 ppm; peppermint, tops at 10 ppm; spearmint, oil at 20 ppm; and peppermint, oil at 20 ppm. This regulation also deletes the existing tolerance in or on cherry at 1.0 ppm, as it is superseded by inclusion in fruit, stone, group 12. VI. Statutory and Executive Order Reviews This final rule establishes tolerances 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 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 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 PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 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) (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). VII. 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).

ACTION: Interim final rule. SUMMARY: This rule implements the statutory change to section 404(e) of the Social Security Act (42 U.S.C. 604(e)) as enacted by the American Recovery and Reinvestment Act of 2009 (Pub. L. 111– 5). This change allows States, Tribes and Territories to use Temporary Assistance for Needy Families (TANF) program funds carried over from a prior year for any allowable TANF benefit, service or activity. Previously these funds could be used only to provide assistance. This interim final rule applies to States, local governments, and Tribes that administer the TANF program. Effective Date: May 27, 2009. Comment Date: Comments are due on or before July 27, 2009. ADDRESSES: You may mail or handdeliver comments regarding this interim rule to the Administration for Children and Families, Office of Family Assistance, 370 L’Enfant Promenade, SW., 5th floor, Washington, DC 20447. You also may transmit comments electronically via the Internet at: PWALKER on PROD1PC71 with RULES VerDate Nov<24>2008 16:09 May 26, 2009 Jkt 217001 Section 417 of the Social Security Act (42 U.S.C. 617) limits the authority of the Federal government to regulate State conduct or enforce the TANF provisions of the Social Security Act, except as expressly provided. We have interpreted this provision to allow us to regulate where Congress has charged HHS with enforcing certain TANF provisions by assessing penalties. Because the improper use of Federal TANF carryover funds can result in a financial penalty pursuant to 42 U.S.C. 609(a)(1), we have the authority to regulate in this instance. Justification for Interim Final Rule AGENCY: DATES: https://www.regulations.gov. You may download an electronic version of this rule at: https://www.regulations.gov. All comments received, including any personal information provided, will be available for public inspection Monday through Friday, 8:30 a.m. to 5 p.m., at 901 D St., SW., 5th Floor, Washington DC. FOR FURTHER INFORMATION CONTACT: Robert Shelbourne, Director, Division of State TANF Policy and Acting Director, Division of Tribal TANF Management, Office of Family Assistance, ACF, at (202) 401–5150. SUPPLEMENTARY INFORMATION: The Administrative Procedures Act requirements under 5 U.S.C. 553 for notice of proposed rulemaking do not apply to rules when the agency finds good cause that notice is impracticable, unnecessary, or contrary to the public interest (5 U.S.C. 553(b)). We find proposed rulemaking unnecessary because the policy was effective upon enactment and this regulatory action merely updates program regulations to reflect current law and avoid any unnecessary confusion on the part of States and Tribes. The change made to the TANF program by the Recovery Act on the use of carry-over funds was intended to provide increased flexibility immediately to States and Tribes to support work and families especially during this difficult economic period. If this regulation were delayed, States and Tribes might be hesitant to take advantage of the flexibility afforded by the statutory change because of the conflict with the regulation, and any confusion resulting from that conflict. For the same reason given above, we also find good cause for waiving the Administrative Procedures Act requirement under 5 U.S.C. 553(d) which provides that a rule generally may not become effective less than 30 days after it is published in the Federal PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 25161 Register. Since the statute was effective upon enactment and because this regulation merely updates the regulations to reflect the current law, this rule is effective upon publication. II. American Recovery and Reinvestment Act of 2009 On February 17, 2009, the President signed the American Recovery and Reinvestment Act of 2009 (Pub. L. 111– 5), which included a provision to lift the restriction on unspent Federal TANF funds reserved or ‘‘carried over’’ into a succeeding fiscal year. Prior to Public Law 111–5, carry-over funds could only be used to provide assistance (i.e., ongoing basic needs payments, and supportive services such as transportation and child care to families who are not employed). Section 2103 of Division B of Public Law 111–5 amends section 404(e) of the Social Security Act (Act) by allowing States, District of Columbia, the Territories and Tribes to use the carry-over funds for any allowable TANF benefit, service, or activity (such as job skills training or retraining activities, employment counseling services, parental counseling services, teen pregnancy prevention activities, services for victims of domestic violence, after-school programs)—and not just assistance. Thus, the policy reflected in this interim final rule is effective immediately and applies to all Federal TANF funds carried over into fiscal year 2009 as well as to all future Federal TANF funds carried over into a subsequent year. Herein after and as defined in section 419(5) of the Social Security Act, we will use ‘‘States’’ to mean the 50 States of the United States, the District of Columbia, the Commonwealth of Puerto Rico, the United States Virgin Islands, Guam, and American Samoa. (However, American Samoa has chosen not to participate in the TANF program.) III. Regulatory Provisions As discussed below, section 2103 of Public Law 111–5 requires a change in the Tribal TANF regulation at 45 CFR 286.60. The TANF regulations at 45 CFR Part 263, applicable to States and Territories, require no change. Part 286—Tribal TANF Provisions Section 286.60: Must Tribes obligate all Tribal Family Assistance Grant funds by the end of the fiscal year in which they are awarded? Under prior law, section 404(e) of the Act, entitled ‘‘Authority to Reserve Certain Amounts for Assistance,’’ allowed States and Indian Tribes E:\FR\FM\27MYR1.SGM 27MYR1

II. Petition for Tolerance

    In the Federal Register of August 13, 2008 (73 FR 47186) (FRL-8375-
8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
8E7347) by IR-4, Rutgers, The State University of New Jersey, 500 
College Road East, Suite 201 W., Princeton, NJ 08540. The petition 
requested that 40 CFR 180.593 be amended by establishing tolerances for 
residues of the insecticide etoxazole, 2-(2,6-difluorophenyl)-4-[4-
(1,1-dimethylethyl)-2-ethoxyphenyl]-4,5-dihydrooxazole, in or on fruit, 
stone, group 12, except plum at 1.0 parts per million (ppm); plum at 
0.12 ppm; plum, prune, dried at 0.4 ppm; cucumber at 0.02 ppm; tomato 
at 0.25; spearmint, tops at 10 ppm; peppermint, tops at 10 ppm; 
peppermint, oil at 20 ppm; and spearmint, oil at 20 ppm. The petition 
additionally requested to delete the tolerance for residues of 
etoxazole in or on the food commodity cherry at 1.0 ppm. That notice 
referenced a summary of the petition prepared on behalf of IR-4 by 
Valent U.S.A. Corporation, the registrant, which is available to the 
public in the docket, https://www.regulations.gov. Comments were 
received on the notice of filing. EPA's response to these comments is 
discussed in Unit IV.C.
    Based upon review of the data supporting the petition, EPA has 
revised the proposed tolerance levels for plum; plum, prune, dried; and 
tomato. The reason for these changes is explained in Unit IV.D.

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 section 408(b)(2)(D) of FFDCA, and the factors 
specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for 
tolerances for residues of etoxazole on fruit, stone, group 12, except 
plum at 1.0 ppm; plum at 0.15 ppm; plum, prune, dried at 0.30 ppm; 
cucumber at 0.02 ppm; tomato at 0.20; spearmint, tops at 10 ppm; 
peppermint, tops at 10 ppm; peppermint, oil at 20 ppm; and spearmint, 
oil at 20 ppm. EPA's assessment of exposures and risks associated with 
establishing tolerances 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 existing etoxazole data indicate that it possess low acute 
toxicity via all routes of exposure. It is not an eye or dermal 
irritant or a dermal sensitizer. No toxicity was seen at the limit dose 
in a 28-day dermal toxicity study in rats.
    The liver is the main target organ in mice, rats and dogs. In a 90-
day toxicity study in dogs, increased liver weights and centrilobular 
hepatocellular swelling in the liver were observed. Similar effects 
were observed in a chronic toxicity study in dogs at similar doses, 
indicating that systemic effects (mainly liver effects) occur at 
similar dose levels following short- through long-term exposure without 
increasing in severity. In a 90-day toxicity study in mice, 
hepatotoxicity (increased relative liver weight, liver enlargement, and 
centrilobular hepatocellular swelling) was observed at high doses. 
Similar effects were observed at the high dose in a mouse 
carcinogenicity study. Subchronic and chronic toxicity studies in rats 
produced similar effects (increased liver weights, centrilobular 
hepatocellular swelling, etc.) to those seen in mice and dogs. In 
addition, slight increases in thyroid weights and incisors were 
observed in subchronic and chronic toxicity studies in rats at high 
doses and at terminal stages of the study. Toxicity was not observed at 
the highest dose tested (HDT) in another carcinogenicity study in mice. 
There is no evidence of immunotoxicity or neurotoxicity in any of the 
submitted studies.
    Two studies in mice showed no evidence of carcinogenicity up to the 
HDT. In a rat carcinogenicity study, which was deemed unacceptable due 
to inadequate dosing, benign interstitial cell tumors (testis) and 
pancreas benign islet cell adenomas were observed (in females) at the 
high dose. These effects were not observed in an acceptable 
carcinogenicity study in rats at higher doses. In special mechanistic 
male rat studies there were no observable

[[Page 25158]]

changes in serum hormone levels (estradiol, luteinizing hormone (LH), 
prolactin and testosterone) or reproductive effects (interstitial cell 
proliferation or spermatogenesis) noted. EPA classified etoxazole as 
``not likely to be carcinogenic to humans.'' Etoxazole is not 
mutagenic.
    The toxicology data for etoxazole provides no indication of 
increased susceptibility, as compared to adults, of rat and rabbit 
fetuses to in utero exposure in developmental studies. The rabbit 
developmental toxicity study included maternal toxic effects (liver 
enlargement, decreased weight gain, and decreased food consumption) at 
the same dose as developmental effects (increased incidences of 27 
presacral vertebrae and 27 presacral vertebrae with 13th ribs). In the 
two-generation reproduction study conducted with rats, offspring 
toxicity was more severe (pup mortality) than parental toxicity 
(increased liver and adrenal weights) at the same dose, indicating 
increased qualitative susceptibility.
    Specific information on the studies received and the nature of the 
adverse effects caused by etoxazole as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level 
(LOAEL) from the toxicity studiescan be found at https://www.regulations.gov in document ``Etoxazole; Human Health Risk 
Assessment for Proposed Uses on Stone Fruits, Cucumber, Tomato, and 
Mint,'' pages 29-31 in docket ID number EPA-HQ-OPP-2008-0554.

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, a toxicological point of departure (POD) is 
identified as the basis for derivation of reference values for risk 
assessment. The POD may be defined as the highest dose at which no 
adverse effects are observed (the NOAEL) in the toxicology study 
identified as appropriate for use in risk assessment. However, if a 
NOAEL cannot be determined, the lowest dose at which adverse effects of 
concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach 
is sometimes used for risk assessment. Uncertainty/safety factors (UFs) 
are used in conjunction with the POD to take into account uncertainties 
inherent in the extrapolation from laboratory animal data to humans and 
in the variations in sensitivity among members of the human population 
as well as other unknowns. Safety is assessed for acute and chronic 
dietary risks by comparing aggregate food and water exposure to the 
pesticide to the acute population adjusted dose (aPAD) and chronic 
population adjusted dose (cPAD). The aPAD and cPAD are calculated by 
dividing the POD by all applicable UFs. Aggregate short-, intermediate-
, and chronic-term risks are evaluated by comparing food, water, and 
residential exposure to the POD to ensure that the margin of exposure 
(MOE) called for by the product of all applicable UFs is not exceeded. 
This latter value is referred to as the Level of Concern (LOC).
    For non-threshold risks, the Agency assumes that any amount of 
exposure will lead to some degree of risk. Thus, the Agency estimates 
risk in terms of the probability of an occurrence of the adverse effect 
greater than that expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for etoxazole used for 
human risk assessment can be found at https://www.regulations.gov in 
document ``Etoxazole; Human Health Risk Assessment for Proposed Uses on 
Stone Fruits, Cucumber, Tomato, and Mint,'' page 15 in docket ID number 
EPA-HQ-OPP-2008-0554.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to etoxazole, EPA considered exposure under the petitioned-for 
tolerances as well as all existing etoxazole tolerances in (40 CFR 
180.593). EPA assessed dietary exposures from etoxazole in food as 
follows:
    i. Acute exposure. Quantitative acute dietary exposure and 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 1-day or single exposure.
    No such effects were identified in the toxicological studies for 
etoxazole; therefore, a quantitative acute dietary exposure assessment 
is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 1994-1996 
and 1998 CSFII. As to residue levels in food, EPA used tolerance-level 
residues and empirically determined (when available) or DEEM default 
processing factors. Additionally, EPA assumed 100 percent crop treated 
(PCT) for all commodities covered by proposed or existing tolerances.
    iii. Cancer. Two mouse studies showed no evidence of 
carcinogenicity at the high dose. While benign interstitial cell tumors 
in the testis and pancreas benign islet cell adenomas were observed in 
an unacceptable rat carcinogenicity study, these effects were not seen 
in a repeat study at higher doses. Furthermore, special mechanistic 
male rat studies resulted in no observable changes in serum hormone 
levels (estradiol, luteinizing hormone, prolactin and testosterone) or 
reproductive effects (interstitial cell proliferation or 
spermatogenesis). EPA determined that cancer risk concerns due to long-
term consumption of etoxazole residues are adequately addressed by the 
chronic dietary exposure analysis; therefore, etoxazole was classified 
as ``not likely to be carcinogenic to humans,'' and a quantitative 
exposure assessment to evaluate cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue or PCT information in the dietary assessment for 
etoxazole. Tolerance level residues and 100 PCT were assumed for all 
food commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for etoxazole in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of etoxazole. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at https://www.epa.gov/oppefed1/models/water/index.htm.
    Based on the First Index Reservoir Screening Tool (FIRST) model for 
surface water, and Screening Concentration in Ground Water (SCI-GROW) 
model for ground water, the estimated drinking water concentrations 
(EDWCs) of etoxazole and its major metabolites (R-8 and R-13) for 
surface water are estimated to be 15.73 parts per billion (ppb) for 
acute exposures and 4.761 ppb for chronic exposures. For ground water, 
the estimated drinking water concentration is estimated to be 0.746 
ppb.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration of value 4.761 ppb was used to 
assess the contribution to drinking water.
    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). Etoxazole

[[Page 25159]]

is not registered for any specific use patterns that would result in 
residential exposure.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of 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.''
    EPA has not found etoxazole to share a common mechanism of toxicity 
with any other substances, and etoxazole does not appear to produce a 
toxic metabolite produced by other substances. For the purposes of this 
tolerance action, therefore, EPA has assumed that etoxazole does not 
have 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 https://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(c) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) 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 based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the FQPA safety 
factor (SF). In applying this provision, EPA either retains the default 
value of 10X, or uses a different additional safety factor when 
reliable data available to EPA support the choice of a different 
factor.
    2. Prenatal and postnatal sensitivity. The toxicology data for 
etoxazole provides no indication of increased susceptibility, as 
compared to adults, of rat and rabbit fetuses to in utero exposure in 
developmental studies. In a rat reproduction study, offspring toxicity 
was more severe (pup mortality) than parental toxicity (increased liver 
and adrenal weights) at the same dose; thereby indicating increased 
qualitative susceptibility. Based on the above concerns, a Degree of 
Concern Analysis was performed by EPA, which concluded that concern is 
low since:
    i. The effects in pups are well-characterized with a clear NOAEL;
    ii. The pup effects occur at the same dose as parental toxicity; 
and
    iii. The doses selected for various risk assessment scenarios are 
lower than the doses that caused offspring toxicity.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1X. That decision is based on the following 
findings:
    i. The toxicity database for etoxazole is complete except for acute 
and subchronic neurotoxicity and immunotoxicity studies. Recent changes 
to 40 CFR 180.158 make acute and subchronic neurotoxicity testing 
(OPPTS Guideline 870.6200), and immunotoxicity testing (OPPTS Guideline 
870.7800) required for pesticide registration. Because these testing 
requirements went into effect shortly before the tolerance petition was 
submitted, these studies are not yet available for etoxazole. However, 
the available data for etoxazole do not show potential for 
immunotoxicity. Further, there is no evidence of neurotoxicity in any 
study in the toxicity database for etoxazole. Therefore, EPA does not 
believe that conducting neurotoxicity and immunotoxicity studies will 
result in a NOAEL lower than the NOAEL of 4.62 milligrams/kilograms/day 
already established for etoxazole. Consequently, an additional database 
uncertainty factor does not need to be applied.
    ii. There is no indication that etoxazole is a neurotoxic chemical 
and there is no need for a developmental neurotoxicity study or 
additional Uncertainity Factors (UFs) to account for neurotoxicity.
    iii. Although there is qualitative evidence of increased 
susceptibility of offspring (pup mortality) compared to less severe 
parental effects (increased liver and adrenal weights) at the same dose 
in the rat multi-generation reproduction study, the Agency did not 
identify any residual uncertainties after establishing toxicity 
endpoints and traditional UFs (10X for interspecies variation and 10X 
for intraspecies variation) to be used in the risk assessment. 
Therefore, there are no residual concerns regarding developmental 
effects in the young.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to etoxazole in drinking water. These assessments 
will not underestimate the exposure and risks posed by etoxazole.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic pesticide exposures are 
safe by comparing aggregate exposure estimates to the aPAD and cPAD. 
The aPAD and cPAD represent the highest safe exposures, taking into 
account all appropriate SFs. EPA calculates the aPAD and cPAD by 
dividing the POD by all applicable UFs. For linear cancer risks, EPA 
calculates the probability of additional cancer cases given the 
estimated aggregate exposure. Short-, intermediate-, and chronic-term 
risks are evaluated by comparing the estimated aggregate food, water, 
and residential exposure to the POD to ensure that the MOE called for 
by the product of all applicable UFs is not exceeded.
    1. Acute risk. An acute aggregate risk assessment takes into 
account exposure estimates from acute dietary consumption of food and 
drinking water. No adverse effect resulting from a single-oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
etoxazole is not expected to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
etoxazole from food and water will utilize 10% of the cPAD for children 
1-2 years old, the population group receiving the greatest exposure. 
There are no residential uses for etoxazole to consider.
    3. Short-, and intermediate-term risk. Short-, and intermediate-
term aggregate exposure takes into account short-, and intermediate-
term residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level).
    Etoxazole is not registered for any use patterns that would result 
in residential exposure. Therefore, the short-, and intermediate-term 
aggregate risk is the sum of the risk from exposure to etoxazole 
through food and water and will not be greater than the chronic 
aggregate risk.
    4. Aggregate cancer risk for U.S. population. As discussed in Unit 
III.C.1.iii., EPA has classified etoxazole as ``not likely to be 
carcinogenic to humans,'' and it is not expected to pose a cancer risk 
to humans.
    5. Determination of safety. Based on these risk assessments, 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 etoxazole residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodologies (gas chromatography/nitrogen-
phosphorus detection (GC/NPD) and gas chromatography/mass selective 
detection (GC/MSD) methods) are available to enforce the tolerance 
expression. The methods 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.

B. International Residue Limits

    Currently, there are no Codex, Canadian, or Mexican maximum residue 
limits (MRLs) established for residues of etoxazole in or on the 
subject commodities.

C. Response to Comments

    EPA received one comment to the Notice of Filing that made a 
general objection to the presence of any pesticide residues on crops 
and stated that EPA should set no pesticide tolerance greater than 
zero. The Agency understands the commenter's concerns and recognizes 
that some individuals believe that pesticides should be banned 
completely. However, the existing legal framework provided by section 
408 of FFDCA states that tolerances greater than zero may be set when 
persons seeking such tolerances or exemptions have demonstrated that 
the pesticide meets the safety standard imposed by that statute. This 
citizen's comment appears to be directed at the underlying statute and 
not EPA's implementation of it; the citizen has made no contention that 
EPA has acted in violation of the statutory framework.

D. Revisions to Petitioned-For Tolerances

    Based upon review of the data supporting the petition, EPA revised 
tolerances for certain proposed commodities, as follows: Plum from 0.12 
ppm to 0.15 ppm; plum, prune, dried from 0.40 ppm to 0.30 ppm; and 
tomato from 0.25 ppm to 0.20 ppm. EPA revised the tolerance levels 
based on analysis of the residue field trial data using the Agency's 
Tolerance Spreadsheet in accordance with the Agency's Guidance for 
Setting Pesticide Tolerances Based on Field Trial Data.

V. Conclusion

    Therefore, tolerances are established for residues of etoxazole, 2-
(2,6-difluorophenyl)-4-[4-(1,1-dimethylethyl)-2-ethoxyphenyl]-4,5-
dihydrooxazole, in or on fruit, stone, group 12, except plum at 1.0 
ppm; plum at 0.15 ppm; plum, prune, dried at 0.30 ppm; cucumber at 0.02 
ppm; tomato at 0.20 ppm; spearmint, tops at 10 ppm; peppermint, tops at 
10 ppm; spearmint, oil at 20 ppm; and peppermint, oil at 20 ppm. This 
regulation also deletes the existing tolerance in or on cherry at 1.0 
ppm, as it is superseded by inclusion in fruit, stone, group 12.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances 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 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 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 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) (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).

VII. 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).
