Background and Statutory Findings EPA, on its own initiative, in accordance with sections 408(e) and 408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, is establishing time-limited tolerances for residues of the fungicide thiabendazole in or on Brussels sprout, cabbage, and cauliflower at 0.05 parts per million (ppm). These tolerances expire and are revoked on December 31, 2009. EPA will publish a document in the Federal Register to remove the revoked tolerances from the Code of Federal Regulations (CFR). Section 408(l)(6) of the FFDCA requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under section 18 of FIFRA. Such tolerances can be established without providing notice or period for public comment. EPA does not intend for its actions on section 18 related tolerances to set binding precedents for the application of section 408 of the FFDCA and the new safety standard to other tolerances and exemptions. Section 408(e) of the FFDCA allows EPA to establish a tolerance or an exemption from the requirement of a tolerance on its own initiative, i.e., without having received any petition from an outside party. PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 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) 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. . . .’’ Section 18 of the FIFRA authorizes EPA to exempt any Federal or State agency from any provision of FIFRA, if EPA determines that ‘‘emergency conditions exist which require such exemption.’’ This provision was not amended by the Food Quality Protection Act of 1996 (FQPA). EPA has established regulations governing such emergency exemptions in 40 CFR part 166. III. Emergency Exemption for Thiabendazole on Brussels sprout, cabbage, nd cauliflower and FFDCA Tolerances The fungus Phoma lingam is the cause of a destructive disease (black leg disease) on crucifer crops and has caused periodic epidemics in the United States. The applicants from California and Washington state that an emergency situation has existed since the registration for the pesticide product that had been the industry standard was cancelled in 2002. The applicants asserted that without the requested use of thiabendazole to control this disease, significant economic losses would occur. EPA has authorized under FIFRA section 18 the use of thiabendazole on Brussels sprout, cabbage, and cauliflower seeds for control of black leg disease caused by Phoma lingam in California and Washington State. After having reviewed the submission, EPA concurs that emergency conditions exist for these States. As part of its assessment of these emergency exemptions, EPA assessed the potential risks presented by residues of thiabendazole in or on Brussels sprout, cabbage, and cauliflower. In doing so, EPA considered the safety E:\FR\FM\31JAR1.SGM 31JAR1 Federal Register / Vol. 72, No. 20 / Wednesday, January 31, 2007 / Rules and Regulations mstockstill on PROD1PC62 with RULES standard in section 408(b)(2) of the FFDCA, and EPA decided that the necessary tolerances under section 408(l)(6) of the FFDCA would be consistent with the safety standard and with FIFRA section 18. Consistent with the need to move quickly on the emergency exemptions in order to address the urgent non-routine situations and to ensure that the resulting food is safe and lawful, EPA is issuing these tolerances without notice and opportunity for public comment as provided in section 408(l)(6) of the FFDCA. Although these tolerances expire and are revoked on December 31, 2009, under section 408(l)(5) of the FFDCA, residues of the pesticide not in excess of the amounts specified in the tolerances remaining in or on Brussels sprout, cabbage, and cauliflower after that date will not be unlawful, provided the pesticide is applied in a manner that was lawful under FIFRA, and the residues do not exceed a level that was authorized by these tolerances at the time of that application. EPA will take action to revoke these tolerances earlier if any experience with, scientific data on, or other relevant information on this pesticide indicate that the residues are not safe. Because these tolerances are being approved under emergency conditions, EPA has not made any decisions about whether thiabendazole meets EPA’s registration requirements for use on Brussels sprout, cabbage, and cauliflower seeds or whether permanent tolerances for these uses would be appropriate. Under these circumstances, EPA does not believe that these timelimited tolerances serve as a basis for registration of thiabendazole by a State for special local needs under FIFRA section 24(c). Nor do these time-limited tolerances serve as the basis for any States other than California and Washington to use this pesticide on these crop seeds under section 18 of FIFRA without following all provisions of EPA’s regulations implementing FIFRA section 18 as identified in 40 CFR part 166. For additional information regarding the emergency exemption for thiabendazole, contact the Agency’s Registration Division at the address provided under FOR FURTHER INFORMATION CONTACT. IV. Aggregate Risk Assessment and Determination of Safety 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 of the FFDCA and a complete description of the risk assessment process, see http:// VerDate Aug<31>2005 15:06 Jan 30, 2007 Jkt 211001 www.epa.gov/fedrgstr/EPA-PEST/1997/ November/Day-26/p30948.htm. 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. EPA has sufficient data to assess the hazards of thiabendazole and to make a determination on aggregate exposure, consistent with section 408(b)(2) of the FFDCA, for time-limited tolerances for residues of thiabendazole in or on Brussels sprout, cabbage, and cauliflower seeds at 0.05 ppm. EPA’s assessment of the dietary exposures and risks associated with establishing these tolerances follows. A. Toxicological Endpoints The dose at which no adverse effects are observed (the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological endpoint. However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect 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. An UF of 100 is routinely used, 10X to account for interspecies differences and 10X for intraspecies differences. For dietary risk assessment (other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose (acute RfD or chronic RfD) where the RfD is equal to the NOAEL divided by the appropriate UF (RfD = NOAEL/ UF). Where an additional safety factor is retained due to concerns unique to the FQPA, this additional factor is applied to the RfD by dividing the RfD by such additional factor. The acute or chronic Population Adjusted Dose (aPAD or cPAD) is a modification of the RfD to accommodate this type of FQPA SF. For non-dietary risk assessments (other than cancer) the UF is used to determine the level of concern (LOC). For example, when 100 is the appropriate UF (10X to account for interspecies differences and 10X for intraspecies differences) the LOC is 100. To estimate risk, a ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is calculated and compared to the LOC. The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify carcinogenic risk. The Q* approach assumes that any amount of exposure PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 4437 will lead to some degree of cancer risk. A Q* is calculated and used to estimate risk which represents a probability of occurrence of additional cancer cases (e.g., risk is expressed as 1 x 106 or one in a million). Under certain specific circumstances, MOE calculations will be used for the carcinogenic risk assessment. In this non-linear approach, a ‘‘point of departure’’ is identified below which carcinogenic effects are not expected. The point of departure is typically a NOAEL based on an endpoint related to cancer effects though it may be a different value derived from the dose response curve. To estimate risk, a ratio of the point of departure to exposure (MOEcancer = point of departure/exposures) is calculated. A summary of the toxicological endpoints used for human risk assessment is discussed in Table 1 on page 8 of the human health risk assessment dated November 20, 2006: Section 18 Exemptions for the Use of Thiabendazole on Brussels sprout, Cabbage, and Cauliflower as a Seed Treatment, available in the docket for this action. B. Exposure Assessment 1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.242) for the residues of thiabendazole in or on a variety of raw agricultural commodities. Tolerances have also been established for thiabendazole and its metabolite 5hydroxythiabendazole at 0.4 ppm in milk, 0.1 ppm in eggs, and 0.1 ppm in meat, fat, and meat byproducts of livestock and poultry. Risk assessments were conducted by EPA to assess dietary exposures from thiabendazole in food as follows: i. Acute exposure. Since there are no toxic effects noted in the database that are likely the result of a single exposure to thiabendazole, no acute dietary endpoints have been selected. ii. Chronic exposure. In conducting this chronic dietary risk assessment the Dietary Exposure Evaluation Model (DEEMTM) analysis evaluated the individual food consumption as reported by respondents in the USDA 1994–1996 and 1998 nationwide Continuing Surveys of Food Intake by Individuals (CSFII) and accumulated exposure to the chemical for each commodity. The following assumptions were made for the chronic exposure assessments: The chronic dietary exposure analysis for thiabendazole is partially refined. For the use of thiabendazole as a seed treatment, the Agency used the analytical method limit of quantitation (LOQ) of 0.05 ppm as the appropriate residue value for Brussels E:\FR\FM\31JAR1.SGM 31JAR1 mstockstill on PROD1PC62 with RULES 4438 Federal Register / Vol. 72, No. 20 / Wednesday, January 31, 2007 / Rules and Regulations sprout, cabbage, and cauliflower and assumed 100% crop treated as inputs into the DEEM chronic dietary analysis. Inputs into the DEEM analysis for all existing uses incorporated PDP data for many commodities, experimental processing factors, anticipated residues for animal commodities and percent crop treated information. Further, estimated thiabendazole residues in drinking water were incorporated directly into the dietary assessment using the highest chronic estimated environmental concentration (EEC) value for surface water. iii. Cancer. Thiabendazole has been classified as ‘‘not likely to be carcinogenic to humans at doses that do not alter rat thyroid hormone homeostasis.’’ Chronic dietary risk is currently being regulated with a chronic RfD that reflects a dose level below the dose levels at which thyroid hormone balance is impacted. Since chronic dietary risk is below the Agency’s level of concern, there is no concern for dietary cancer risk arising from existing uses as well as the use of thiabendazole as a seed treatment on Brussels sprout, cabbage, and cauliflower. 2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for thiabendazole in drinking water. Because the Agency does not have comprehensive monitoring data, drinking water concentration estimates are made by reliance on simulation or modeling taking into account data on the physical characteristics of thiabendazole. Further, information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/ oppefed1/models/water/index.htm. The treatment of seeds for purposes of the section 18 request is expected to be an indoor activity with no potential concern for leaching to ground water or run off to surface water. However, there is some potential for transfer of residues of thiabendazole to the environment with the planting of treated seed in the field. Drinking water was incorporated directly into the dietary assessment by extrapolation of the drinking water concentrations generated as a result of planting treated seed. Based on the GENEEC and SCI-GROW models, the estimated environmental concentrations (EECs) of for acute exposures are estimated to be 2.4 parts per billion (ppb) for surface water and 0.01 ppb for ground water. The EECs for chronic exposures are estimated to be 0.52 ppb for surface water and 0.01 ppb for ground water. VerDate Aug<31>2005 15:06 Jan 30, 2007 Jkt 211001 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). The Agency has concluded that there is low potential for residential exposure based on thiabendazole’s use profile, and the proposed section 18 uses of thiabendazole on Brussels sprout, cabbage, and cauliflower seeds do not result in new residential exposure scenarios. Currently, there are no thiabendazole products registered for use by residential users. However, thiabendazole is incorporated in low concentrations into paints, adhesives, paper, and carpet. This incorporation greatly reduces the potential for exposure. The Agency has calculated worst case scenarios for thiabendazole exposure to thiabendazole treated carpet and paint. A summary of the residential exposure and risk estimates for thiabendazole are summarized in Table 6 on page 16 of the human health risk assessment dated November 20, 2006: Section 18 Exemptions for the Use of Thiabendazole on Brussels sprout, Cabbage, and Cauliflower as a Seed Treatment, available in the docket for this action. 4. Cumulative effects from substances with a common mechanism of toxicity. 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 thiabendazole and any other substances and thiabendazole 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 thiabendazole 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 policy statements released by EPA’s Office of Pesticide Programs concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 mechanism on EPA’s website at http:// www.epa.gov/pesticides/cumulative/. C. Safety Factor for Infants and Children 1. In general. 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. 2. Developmental toxicity studies. The toxicity database for thiabendazole includes an acceptable prenatal developmental toxicity study in rats and rabbits, which shows no increased sensitivity to fetuses. A neurotoxicity study is not required since there is no evidence in the database that supports a requirement for a developmental neurotoxicity study. 3. Reproductive toxicity study. Based on data submitted to the Agency as well as data from the open literature, there was no evidence of reproductive toxicity in the prenatal developmental toxicity studies in rats, rabbits, and mice or in the two-generation reproduction study in rats. 4. Prenatal and postnatal sensitivity. There is no evidence of increased susceptibility in rats, rabbits, or mice to in utero or early postnatal exposure to thiabendazole based on the prenatal developmental toxicity study rats, rabbits, and mice and in the twogenerations reproduction study in rats. The developmental effects in the fetuses occurred at or above doses that caused maternal or paternal toxicity. 5. Conclusion. There is a complete toxicity database for thiabendazole and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. In terms of hazard, there are low concerns and no residual uncertainties regarding prenatal and/or postnatal toxicity. D. Aggregate Risks and Determination of Safety The Agency currently has two ways to estimate total aggregate exposure to a pesticide from food, drinking water, and residential uses. First, a screening assessment can be used, in which the Agency calculates drinking water levels of comparison (DWLOCs), which are used as a point of comparison against estimated drinking water concentrations E:\FR\FM\31JAR1.SGM 31JAR1 mstockstill on PROD1PC62 with RULES Federal Register / Vol. 72, No. 20 / Wednesday, January 31, 2007 / Rules and Regulations (EDWCs). The DWLOC values are not regulatory standards for drinking water, but are theoretical upper limits on a pesticide’s concentration in drinking water in light of total aggregate exposure to a pesticide in food and residential uses. More information on the use of DWLOCs in dietary aggregate risk assessments can be found at http:/ www.epa.gov/oppfead1/trac/science/ screeningsop.pdf. More recently, the Agency has used another approach to estimate aggregate exposure through food, residential and drinking water pathways. In this approach, modeled surface water and ground water EDWCs are directly incorporated into the dietary exposure analysis, along with food. This approach provides a more realistic estimate of exposure because actual body weights and water exposures are then added to estimated and water consumption form the CSFII are used. The combined food and water exposures are then added to estimated exposure from residential sources to calculate aggregate risks. The resulting exposure and risk estimates are still considered to be high end, due to the assumptions used in developing drinking water modeling inputs. The risk assessment for thiabendazole used in this tolerance document uses this approach of incorporating water exposure directly into the dietary exposure analysis. EPA conducted partially refined chronic dietary assessments, which included the use of thiabendazole used as a seed treatment in/on Brussels sprout, cabbage, cauliflower seeds in addition to the existing use for thiabendazole that results in a chronic dietary exposure (food and water) for the U.S. population equivalent to 1.4% of the cPAD. The most highly exposed population subgroup is children 1 to 2 years of age with a chronic dietary exposure (food and water) which is equivalent to 4.2% of the cPAD. Since chronic dietary (food and water) estimates of risk for the U.S. population and all subgroups are below 100% of the cPAD, the Agency has no concern for chronic dietary risk from the use of thiabendazole as a seed treatment for use on Brussels sprout, cabbage, and cauliflower seeds. 1. Acute risk. EPA did not assess acute dietary risk for thiabendazole because no acute dietary endpoint of concern was identified for the general population or any subpopulation. 2. Chronic risk. EPA concluded that chronic aggregate exposure to thiabendazole from food and water will utilize 4.2% of the cPAD for the most highly exposed population subgroup, which is children 1 to 2 years of age. VerDate Aug<31>2005 15:06 Jan 30, 2007 Jkt 211001 This chronic aggregate risk estimate is based on dietary risk from food and water. Since the estimated thiabendazole chronic aggregate dietary exposure from food and water for the general population and all subpopulations results in an estimated risk value less than 100% of the cPAD, EPA has no concern for chronic aggregate risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to from food will utilize 1.4% of the cPAD for the U.S. population, 4.2% of the cPAD for the most highly exposed subpopulation (children 1–2 years of age) and 1.2 % of the cPAD for females 13 to 49 years of age. 3. Short and Intermediate-term risk. Short-and intermediate-term aggregate exposure takes into account non-dietary, non-occupational exposure plus chronic exposure to food and water (considered to be a background exposure level). EPA does not expect short-and intermediateterm aggregate exposure to exceed the Agency’s level of concern. The Agency has concluded that there is low potential for residential exposure based on thiabendazole’s use profile. There are currently no thiabendazole products registered for use by residential users. However, thiabendazole is incorporated in low concentrations into paints, adhesives, paper, and carpet. This incorporation greatly reduces the potential for exposure. To assess shortand intermediate-term aggregate exposure likely to result from the use of thiabendazole on Brussels sprout, cabbage, and cauliflower as a seed treatment, as well as existing uses, the Agency combined average food and water exposure values with estimates of residential exposure. For adult populations, the Agency assumed that both painting with thiabendazole treated paint and contact with thiabendazole treated carpet could occur simultaneously and combined those exposures for the purpose of calculating the aggregate risk estimates. For infant and child populations, the Agency assumed that residential exposure was a result of contact with treated carpet only. More detailed information on the short-and intermediate-term exposure and risk estimates for thiabendazole are summarized and can be found in the document entitled Section 18 Exemptions for the Use of Thiabendazole on Brussels sprout, Cabbage, and Cauliflower as a Seed Treatment, dated November 20, 2006 in Table 7 on page 17 of the human health risk assessment, by going to http:www.regulations.gov, and searching PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 4439 for docket ID number EPA–HQ–OPP– 2006–0962. Double - click on the document to view the referenced information. 4. Aggregate cancer risk for U.S. population. Thiabendazole has been classified as ‘‘not likely to be carcinogenic to humans at doses that do not alter rat thyroid hormone homeostasis.’’ Since the chronic aggregate exposure is below the level that would alter rat thyroid hormone homeostasis, there is no concern for aggregate cancer risk arising from existing uses or the use of thiabendazole use as a seed treatment in/on Brussels sprout, cabbage, and cauliflower seeds. 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 and to infants and children from aggregate exposure to thiabendazole residues. V. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (example—gas chromatography) is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755–5350; telephone number: (410) 305–2905; e-mail address: residuemethods@epa.gov. B. International Residue Limits No specific CODEX, Canadian or Mexican maximum residue limits (MRLs) or tolerances have been established for thiabendazole in or on Brussels sprout, cabbage, or cauliflower. Therefore, international harmonization is not an issue at this time. VI. Conclusion Therefore, time-limited tolerances are established for residues of thiabendazole in or on Brussels sprout, cabbage, or cauliflower at 0.05 ppm. These tolerances expire and are revoked on December 31, 2009. VII. Statutory and Executive Order Reviews This final rule establishes timelimited tolerances under section 408 of the FFDCA. 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, E:\FR\FM\31JAR1.SGM 31JAR1 4440 Federal Register / Vol. 72, No. 20 / Wednesday, January 31, 2007 / Rules and Regulations 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 FIFRA section 18 exemption under section 408 of the FFDCA, such as the tolerances 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 section 408(n)(4) of the FFDCA. 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. Congressional Review Act 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).

II. Background and Statutory Findings

    EPA, on its own initiative, in accordance with sections 408(e) and 
408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 
U.S.C. 346a, is establishing time-limited tolerances for residues of 
the fungicide thiabendazole in or on Brussels sprout, cabbage, and 
cauliflower at 0.05 parts per million (ppm). These tolerances expire 
and are revoked on December 31, 2009. EPA will publish a document in 
the Federal Register to remove the revoked tolerances from the Code of 
Federal Regulations (CFR).
    Section 408(l)(6) of the FFDCA requires EPA to establish a time-
limited tolerance or exemption from the requirement for a tolerance for 
pesticide chemical residues in food that will result from the use of a 
pesticide under an emergency exemption granted by EPA under section 18 
of FIFRA. Such tolerances can be established without providing notice 
or period for public comment. EPA does not intend for its actions on 
section 18 related tolerances to set binding precedents for the 
application of section 408 of the FFDCA and the new safety standard to 
other tolerances and exemptions. Section 408(e) of the FFDCA allows EPA 
to establish a tolerance or an exemption from the requirement of a 
tolerance on its own initiative, i.e., without having received any 
petition from an outside party.
    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) 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. . . 
.''
    Section 18 of the FIFRA authorizes EPA to exempt any Federal or 
State agency from any provision of FIFRA, if EPA determines that 
``emergency conditions exist which require such exemption.'' This 
provision was not amended by the Food Quality Protection Act of 1996 
(FQPA). EPA has established regulations governing such emergency 
exemptions in 40 CFR part 166.

III. Emergency Exemption for Thiabendazole on Brussels sprout, cabbage, 
nd cauliflower and FFDCA Tolerances

    The fungus Phoma lingam is the cause of a destructive disease 
(black leg disease) on crucifer crops and has caused periodic epidemics 
in the United States. The applicants from California and Washington 
state that an emergency situation has existed since the registration 
for the pesticide product that had been the industry standard was 
cancelled in 2002. The applicants asserted that without the requested 
use of thiabendazole to control this disease, significant economic 
losses would occur. EPA has authorized under FIFRA section 18 the use 
of thiabendazole on Brussels sprout, cabbage, and cauliflower seeds for 
control of black leg disease caused by Phoma lingam in California and 
Washington State. After having reviewed the submission, EPA concurs 
that emergency conditions exist for these States.
    As part of its assessment of these emergency exemptions, EPA 
assessed the potential risks presented by residues of thiabendazole in 
or on Brussels sprout, cabbage, and cauliflower. In doing so, EPA 
considered the safety

[[Page 4437]]

standard in section 408(b)(2) of the FFDCA, and EPA decided that the 
necessary tolerances under section 408(l)(6) of the FFDCA would be 
consistent with the safety standard and with FIFRA section 18. 
Consistent with the need to move quickly on the emergency exemptions in 
order to address the urgent non-routine situations and to ensure that 
the resulting food is safe and lawful, EPA is issuing these tolerances 
without notice and opportunity for public comment as provided in 
section 408(l)(6) of the FFDCA. Although these tolerances expire and 
are revoked on December 31, 2009, under section 408(l)(5) of the FFDCA, 
residues of the pesticide not in excess of the amounts specified in the 
tolerances remaining in or on Brussels sprout, cabbage, and cauliflower 
after that date will not be unlawful, provided the pesticide is applied 
in a manner that was lawful under FIFRA, and the residues do not exceed 
a level that was authorized by these tolerances at the time of that 
application. EPA will take action to revoke these tolerances earlier if 
any experience with, scientific data on, or other relevant information 
on this pesticide indicate that the residues are not safe.
    Because these tolerances are being approved under emergency 
conditions, EPA has not made any decisions about whether thiabendazole 
meets EPA's registration requirements for use on Brussels sprout, 
cabbage, and cauliflower seeds or whether permanent tolerances for 
these uses would be appropriate. Under these circumstances, EPA does 
not believe that these time-limited tolerances serve as a basis for 
registration of thiabendazole by a State for special local needs under 
FIFRA section 24(c). Nor do these time-limited tolerances serve as the 
basis for any States other than California and Washington to use this 
pesticide on these crop seeds under section 18 of FIFRA without 
following all provisions of EPA's regulations implementing FIFRA 
section 18 as identified in 40 CFR part 166. For additional information 
regarding the emergency exemption for thiabendazole, contact the 
Agency's Registration Division at the address provided under FOR 
FURTHER INFORMATION CONTACT.

IV. Aggregate Risk Assessment and Determination of Safety

    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 of the FFDCA and a complete 
description of the risk assessment process, see http://www.epa.gov/
fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
    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. EPA has sufficient data to assess the hazards of 
thiabendazole and to make a determination on aggregate exposure, 
consistent with section 408(b)(2) of the FFDCA, for time-limited 
tolerances for residues of thiabendazole in or on Brussels sprout, 
cabbage, and cauliflower seeds at 0.05 ppm. EPA's assessment of the 
dietary exposures and risks associated with establishing these 
tolerances follows.

A. Toxicological Endpoints

    The dose at which no adverse effects are observed (the NOAEL) from 
the toxicology study identified as appropriate for use in risk 
assessment is used to estimate the toxicological endpoint. However, the 
lowest dose at which adverse effects of concern are identified (the 
LOAEL) is sometimes used for risk assessment if no NOAEL was achieved 
in the toxicology study selected. An uncertainty factor (UF) is applied 
to reflect 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. An UF of 100 
is routinely used, 10X to account for interspecies differences and 10X 
for intraspecies differences.
    For dietary risk assessment (other than cancer) the Agency uses the 
UF to calculate an acute or chronic reference dose (acute RfD or 
chronic RfD) where the RfD is equal to the NOAEL divided by the 
appropriate UF (RfD = NOAEL/UF). Where an additional safety factor is 
retained due to concerns unique to the FQPA, this additional factor is 
applied to the RfD by dividing the RfD by such additional factor. The 
acute or chronic Population Adjusted Dose (aPAD or cPAD) is a 
modification of the RfD to accommodate this type of FQPA SF.
    For non-dietary risk assessments (other than cancer) the UF is used 
to determine the level of concern (LOC). For example, when 100 is the 
appropriate UF (10X to account for interspecies differences and 10X for 
intraspecies differences) the LOC is 100. To estimate risk, a ratio of 
the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is 
calculated and compared to the LOC.
    The linear default risk methodology (Q*) is the primary method 
currently used by the Agency to quantify carcinogenic risk. The Q* 
approach assumes that any amount of exposure will lead to some degree 
of cancer risk. A Q* is calculated and used to estimate risk which 
represents a probability of occurrence of additional cancer cases 
(e.g., risk is expressed as 1 x 10\6\ or one in a million). Under 
certain specific circumstances, MOE calculations will be used for the 
carcinogenic risk assessment. In this non-linear approach, a ``point of 
departure'' is identified below which carcinogenic effects are not 
expected. The point of departure is typically a NOAEL based on an 
endpoint related to cancer effects though it may be a different value 
derived from the dose response curve. To estimate risk, a ratio of the 
point of departure to exposure (MOEcancer = point of 
departure/exposures) is calculated. A summary of the toxicological 
endpoints used for human risk assessment is discussed in Table 1 on 
page 8 of the human health risk assessment dated November 20, 2006: 
Section 18 Exemptions for the Use of Thiabendazole on Brussels sprout, 
Cabbage, and Cauliflower as a Seed Treatment, available in the docket 
for this action.

B. Exposure Assessment

    1. Dietary exposure from food and feed uses. Tolerances have been 
established (40 CFR 180.242) for the residues of thiabendazole in or on 
a variety of raw agricultural commodities. Tolerances have also been 
established for thiabendazole and its metabolite 5-hydroxythiabendazole 
at 0.4 ppm in milk, 0.1 ppm in eggs, and 0.1 ppm in meat, fat, and meat 
byproducts of livestock and poultry. Risk assessments were conducted by 
EPA to assess dietary exposures from thiabendazole in food as follows:
    i. Acute exposure. Since there are no toxic effects noted in the 
database that are likely the result of a single exposure to 
thiabendazole, no acute dietary endpoints have been selected.
    ii. Chronic exposure. In conducting this chronic dietary risk 
assessment the Dietary Exposure Evaluation Model (DEEMTM) 
analysis evaluated the individual food consumption as reported by 
respondents in the USDA 1994-1996 and 1998 nationwide Continuing 
Surveys of Food Intake by Individuals (CSFII) and accumulated exposure 
to the chemical for each commodity. The following assumptions were made 
for the chronic exposure assessments: The chronic dietary exposure 
analysis for thiabendazole is partially refined. For the use of 
thiabendazole as a seed treatment, the Agency used the analytical 
method limit of quantitation (LOQ) of 0.05 ppm as the appropriate 
residue value for Brussels

[[Page 4438]]

sprout, cabbage, and cauliflower and assumed 100% crop treated as 
inputs into the DEEM chronic dietary analysis. Inputs into the DEEM 
analysis for all existing uses incorporated PDP data for many 
commodities, experimental processing factors, anticipated residues for 
animal commodities and percent crop treated information. Further, 
estimated thiabendazole residues in drinking water were incorporated 
directly into the dietary assessment using the highest chronic 
estimated environmental concentration (EEC) value for surface water.
    iii. Cancer. Thiabendazole has been classified as ``not likely to 
be carcinogenic to humans at doses that do not alter rat thyroid 
hormone homeostasis.'' Chronic dietary risk is currently being 
regulated with a chronic RfD that reflects a dose level below the dose 
levels at which thyroid hormone balance is impacted. Since chronic 
dietary risk is below the Agency's level of concern, there is no 
concern for dietary cancer risk arising from existing uses as well as 
the use of thiabendazole as a seed treatment on Brussels sprout, 
cabbage, and cauliflower.
    2. Dietary exposure from drinking water. The Agency lacks 
sufficient monitoring exposure data to complete a comprehensive dietary 
exposure analysis and risk assessment for thiabendazole in drinking 
water. Because the Agency does not have comprehensive monitoring data, 
drinking water concentration estimates are made by reliance on 
simulation or modeling taking into account data on the physical 
characteristics of thiabendazole. Further, information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at http://www.epa.gov/oppefed1/models/water/index.htm.
    The treatment of seeds for purposes of the section 18 request is 
expected to be an indoor activity with no potential concern for 
leaching to ground water or run off to surface water. However, there is 
some potential for transfer of residues of thiabendazole to the 
environment with the planting of treated seed in the field. Drinking 
water was incorporated directly into the dietary assessment by 
extrapolation of the drinking water concentrations generated as a 
result of planting treated seed. Based on the GENEEC and SCI-GROW 
models, the estimated environmental concentrations (EECs) of for acute 
exposures are estimated to be 2.4 parts per billion (ppb) for surface 
water and 0.01 ppb for ground water. The EECs for chronic exposures are 
estimated to be 0.52 ppb for surface water and 0.01 ppb for ground 
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). The Agency has 
concluded that there is low potential for residential exposure based on 
thiabendazole's use profile, and the proposed section 18 uses of 
thiabendazole on Brussels sprout, cabbage, and cauliflower seeds do not 
result in new residential exposure scenarios. Currently, there are no 
thiabendazole products registered for use by residential users. 
However, thiabendazole is incorporated in low concentrations into 
paints, adhesives, paper, and carpet. This incorporation greatly 
reduces the potential for exposure. The Agency has calculated worst 
case scenarios for thiabendazole exposure to thiabendazole treated 
carpet and paint. A summary of the residential exposure and risk 
estimates for thiabendazole are summarized in Table 6 on page 16 of the 
human health risk assessment dated November 20, 2006: Section 18 
Exemptions for the Use of Thiabendazole on Brussels sprout, Cabbage, 
and Cauliflower as a Seed Treatment, available in the docket for this 
action.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. 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 thiabendazole and any 
other substances and thiabendazole 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 thiabendazole 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 policy statements released by EPA's Office of 
Pesticide Programs concerning common mechanism determinations and 
procedures for cumulating effects from substances found to have a 
common mechanism on EPA's website at http://www.epa.gov/pesticides/
cumulative/.

C. Safety Factor for Infants and Children

    1. In general. 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.
    2. Developmental toxicity studies. The toxicity database for 
thiabendazole includes an acceptable prenatal developmental toxicity 
study in rats and rabbits, which shows no increased sensitivity to 
fetuses. A neurotoxicity study is not required since there is no 
evidence in the database that supports a requirement for a 
developmental neurotoxicity study.
    3. Reproductive toxicity study. Based on data submitted to the 
Agency as well as data from the open literature, there was no evidence 
of reproductive toxicity in the prenatal developmental toxicity studies 
in rats, rabbits, and mice or in the two-generation reproduction study 
in rats.
    4. Prenatal and postnatal sensitivity. There is no evidence of 
increased susceptibility in rats, rabbits, or mice to in utero or early 
postnatal exposure to thiabendazole based on the prenatal developmental 
toxicity study rats, rabbits, and mice and in the two-generations 
reproduction study in rats. The developmental effects in the fetuses 
occurred at or above doses that caused maternal or paternal toxicity.
    5. Conclusion. There is a complete toxicity database for 
thiabendazole and exposure data are complete or are estimated based on 
data that reasonably accounts for potential exposures. In terms of 
hazard, there are low concerns and no residual uncertainties regarding 
prenatal and/or postnatal toxicity.

D. Aggregate Risks and Determination of Safety

    The Agency currently has two ways to estimate total aggregate 
exposure to a pesticide from food, drinking water, and residential 
uses. First, a screening assessment can be used, in which the Agency 
calculates drinking water levels of comparison (DWLOCs), which are used 
as a point of comparison against estimated drinking water 
concentrations

[[Page 4439]]

(EDWCs). The DWLOC values are not regulatory standards for drinking 
water, but are theoretical upper limits on a pesticide's concentration 
in drinking water in light of total aggregate exposure to a pesticide 
in food and residential uses. More information on the use of DWLOCs in 
dietary aggregate risk assessments can be found at http:/www.epa.gov/
oppfead1/trac/science/screeningsop.pdf. More recently, the Agency has 
used another approach to estimate aggregate exposure through food, 
residential and drinking water pathways. In this approach, modeled 
surface water and ground water EDWCs are directly incorporated into the 
dietary exposure analysis, along with food. This approach provides a 
more realistic estimate of exposure because actual body weights and 
water exposures are then added to estimated and water consumption form 
the CSFII are used. The combined food and water exposures are then 
added to estimated exposure from residential sources to calculate 
aggregate risks. The resulting exposure and risk estimates are still 
considered to be high end, due to the assumptions used in developing 
drinking water modeling inputs. The risk assessment for thiabendazole 
used in this tolerance document uses this approach of incorporating 
water exposure directly into the dietary exposure analysis.
    EPA conducted partially refined chronic dietary assessments, which 
included the use of thiabendazole used as a seed treatment in/on 
Brussels sprout, cabbage, cauliflower seeds in addition to the existing 
use for thiabendazole that results in a chronic dietary exposure (food 
and water) for the U.S. population equivalent to 1.4% of the cPAD. The 
most highly exposed population subgroup is children 1 to 2 years of age 
with a chronic dietary exposure (food and water) which is equivalent to 
4.2% of the cPAD. Since chronic dietary (food and water) estimates of 
risk for the U.S. population and all subgroups are below 100% of the 
cPAD, the Agency has no concern for chronic dietary risk from the use 
of thiabendazole as a seed treatment for use on Brussels sprout, 
cabbage, and cauliflower seeds.
    1. Acute risk. EPA did not assess acute dietary risk for 
thiabendazole because no acute dietary endpoint of concern was 
identified for the general population or any subpopulation.
    2. Chronic risk. EPA concluded that chronic aggregate exposure to 
thiabendazole from food and water will utilize 4.2% of the cPAD for the 
most highly exposed population subgroup, which is children 1 to 2 years 
of age. This chronic aggregate risk estimate is based on dietary risk 
from food and water. Since the estimated thiabendazole chronic 
aggregate dietary exposure from food and water for the general 
population and all subpopulations results in an estimated risk value 
less than 100% of the cPAD, EPA has no concern for chronic aggregate 
risk. Using the exposure assumptions described in this unit for chronic 
exposure, EPA has concluded that exposure to from food will utilize 
1.4% of the cPAD for the U.S. population, 4.2% of the cPAD for the most 
highly exposed subpopulation (children 1-2 years of age) and 1.2 % of 
the cPAD for females 13 to 49 years of age.
    3. Short and Intermediate-term risk. Short-and intermediate-term 
aggregate exposure takes into account non-dietary, non-occupational 
exposure plus chronic exposure to food and water (considered to be a 
background exposure level). EPA does not expect short-and intermediate-
term aggregate exposure to exceed the Agency's level of concern. The 
Agency has concluded that there is low potential for residential 
exposure based on thiabendazole's use profile. There are currently no 
thiabendazole products registered for use by residential users. 
However, thiabendazole is incorporated in low concentrations into 
paints, adhesives, paper, and carpet. This incorporation greatly 
reduces the potential for exposure. To assess short-and intermediate-
term aggregate exposure likely to result from the use of thiabendazole 
on Brussels sprout, cabbage, and cauliflower as a seed treatment, as 
well as existing uses, the Agency combined average food and water 
exposure values with estimates of residential exposure. For adult 
populations, the Agency assumed that both painting with thiabendazole 
treated paint and contact with thiabendazole treated carpet could occur 
simultaneously and combined those exposures for the purpose of 
calculating the aggregate risk estimates. For infant and child 
populations, the Agency assumed that residential exposure was a result 
of contact with treated carpet only.
    More detailed information on the short-and intermediate-term 
exposure and risk estimates for thiabendazole are summarized and can be 
found in the document entitled Section 18 Exemptions for the Use of 
Thiabendazole on Brussels sprout, Cabbage, and Cauliflower as a Seed 
Treatment, dated November 20, 2006 in Table 7 on page 17 of the human 
health risk assessment, by going to http:www.regulations.gov, and 
searching for docket ID number EPA-HQ-OPP-2006-0962. Double - click on 
the document to view the referenced information.
    4. Aggregate cancer risk for U.S. population. Thiabendazole has 
been classified as ``not likely to be carcinogenic to humans at doses 
that do not alter rat thyroid hormone homeostasis.'' Since the chronic 
aggregate exposure is below the level that would alter rat thyroid 
hormone homeostasis, there is no concern for aggregate cancer risk 
arising from existing uses or the use of thiabendazole use as a seed 
treatment in/on Brussels sprout, cabbage, and cauliflower seeds.
    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 and to infants and children from aggregate 
exposure to thiabendazole residues.

V. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (example--gas chromatography) is 
available to enforce the tolerance expression. The method may be 
requested from: Chief, Analytical Chemistry Branch, Environmental 
Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone 
number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

    No specific CODEX, Canadian or Mexican maximum residue limits 
(MRLs) or tolerances have been established for thiabendazole in or on 
Brussels sprout, cabbage, or cauliflower. Therefore, international 
harmonization is not an issue at this time.

VI. Conclusion

    Therefore, time-limited tolerances are established for residues of 
thiabendazole in or on Brussels sprout, cabbage, or cauliflower at 0.05 
ppm. These tolerances expire and are revoked on December 31, 2009.

VII. Statutory and Executive Order Reviews

    This final rule establishes time-limited tolerances under section 
408 of the FFDCA. 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,

[[Page 4440]]

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 FIFRA 
section 18 exemption under section 408 of the FFDCA, such as the 
tolerances 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 section 408(n)(4) of the 
FFDCA. 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. Congressional Review Act

    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).
