The PIRIB telephone number is (703) 305-5805. II. Background and Statutory Findings EPA, on its own initiative, in accordance with sections 408 (l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, is establishing a tolerance for residues of the herbicide ethametsulfuron-methyl, in or on canola at 0.02 part per million (ppm). This tolerance will expire and is revoked on December 31, 2001. EPA will publish a document in the 
                    **Federal Register**
                     to remove the revoked tolerance from the Code of Federal Regulations. 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 and the new safety standard to other tolerances and exemptions. Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) defines “safe” to mean that “there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .” Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (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 (FQPA). EPA has established regulations governing such emergency exemptions in 40 CFR part 166. III. Emergency Exemption for Ethametsulfuron-methyl on Canola and FFDCA Tolerances EPA has authorized under FIFRA section 18 the use of ethametsulfuron-methyl on canola for control of smartweeds in North Dakota and Minnesota. Products containing endothall had been available for use against smartweeds in the past. However, this use of endothall is no longer being supported. Therefore, after considering the situation this year, EPA determined that emergency conditions existed for the growers and permitted the use. As part of its assessment of this emergency exemption, EPA assessed the potential risks presented by residues of ethametsulfuron-methyl in or on canola. In doing so, EPA considered the safety standard in FFDCA section 408(b)(2), and EPA decided that the necessary tolerance under FFDCA section 408(l)(6) would be consistent with the safety standard and with FIFRA section 18. Consistent with the need to move quickly on the emergency exemption in order to address an urgent non-routine situation and to ensure that the resulting food is safe and lawful, EPA is issuing this tolerance without notice and opportunity for public comment as provided in section 408(l)(6). Although this tolerance will expire and is revoked on December 31, 2001, under FFDCA section 408(l)(5), residues of the pesticide not in excess of the amounts specified in the tolerance remaining in or on canola 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 this tolerance at the time of that application. EPA will take action to revoke this tolerance earlier if any experience with, scientific data on, or other relevant information on this pesticide indicate that the residues are not safe. Because this tolerance is being approved under emergency conditions, EPA has not made any decisions about whether ethametsulfuron-methyl meets EPA's registration requirements for use 
                    ( print page 57968)
                    on canola or whether a permanent tolerance for this use would be appropriate. Under these circumstances, EPA does not believe that this tolerance serves as a basis for registration of ethametsulfuron-methyl by a State for special local needs under FIFRA section 24(c). Nor does this tolerance serve as the basis for any State other than North Dakota and Minnesota to use this pesticide on this crop under section 18 of FIFRA without following all provisions of EPA's regulations implementing section 18 as identified in 40 CFR part 166.

                    **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 and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7). Consistent with section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of ethametsulfuron-methyl and to make a determination on aggregate exposure, consistent with section 408(b)(2), for a time-limited tolerance for ethametsulfuron-methyl in or on canola at 0.02 ppm. EPA's assessment of the dietary exposures and risks associated with establishing the tolerance follows. A. Toxicological Endpoints The dose at which no observed adverse effect level (NOAEL) are observed from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological endpoint. However, the lowest observed adverse effect level (LOAEL) at which adverse effects of concern are identified 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 Safety Factor. 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 for ethametsulfuron-methyl used for human risk assessment is shown in the following Table 1. **Table 1. — Summary of Toxicological Dose and Endpoints for Ethametsulfuron-methyl for Use in Human Risk Assessment**

 B. Exposure Assessment 1. 
                    *Dietary exposure from food and feed uses.*
                     This is the first food use tolerance that will be established for this herbicide. In support of this action, risk assessments were conducted by EPA to assess dietary exposures from ethametsulfuron-methyl in food as follows: i. 
                    *Acute exposure.*
                     Acute dietary risk assessments are performed for a food-use pesticide if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a one day or single exposure. For this action, no acute dietary risk assessment was conducted. The rationale for this is that a dose and endpoint were not selected since toxicological effects attributable to a single dose (exposure) were not available from the oral toxicology studies, including developmental toxicity studies in rats and rabbits. ii. 
                    *Chronic exposure*. In conducting this chronic dietary risk assessment the dietary exposure evaluation model (DEEM) analysis evaluated the individual food consumption as reported by respondents in the USDA 1989-1992 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: A conservative Tier I analysis using tolerance level residues was performed. Besides the use connected with this action, there are no other food use or residential registrations for ethametsulfuron-methyl. Percent crop-treated refinements and anticipated residues were not used. iii. 
                    *Cancer*. EPA did not conduct a quantitative cancer risk assessment for this action. The basis for this decision is that no evidence of chronic toxicity or carcinogenicity was seen in mice and rats; although, the dose levels tested in these studies were determined to be inadequate. The cancer potential for other sulfonylurea herbicides is also germane to this decision. Other sulfonylurea herbicides do not show evidence of carcinogenicity or mutagenicity. 2. 
                    *Dietary exposure from drinking water.*
                    The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for ethametsulfuron-methyl 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 ethametsulfuron-methyl. The Agency uses the Generic Estimated Environmental Concentration (GENEEC) or the Pesticide Root Zone/Exposure Analysis Modeling System (PRZM/EXAMS) to estimate pesticide concentrations in surface water and Screening Concentration in Ground Water (SCI-GROW), which predicts pesticide concentrations in ground water. In general, EPA will use GENEEC (a tier 1 model) before using PRZM/EXAMS (a tier 2 model) for a screening-level assessment for surface water. The GENEEC model is a subset of the PRZM/EXAMS model that uses a specific high-end runoff scenario for pesticides. GENEEC incorporates a farm pond scenario, while PRZM/EXAMS incorporate an index reservoir environment in place of the previous pond scenario. The PRZM/EXAMS model includes a percent crop area factor as an adjustment to account for the maximum percent crop coverage within a watershed or drainage basin. None of these models include consideration of the impact processing (mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The primary use of these models by the Agency at this stage is to provide a coarse screen for sorting out pesticides for which it is highly unlikely that drinking water concentrations would ever exceed human health levels of concern. Since the models used are considered to be screening tools in the risk assessment process, the Agency does not use estimated environmental concentrations (EECs) from these models to quantify drinking water exposure and risk as a %%RfD or %%PAD. Instead drinking water levels of comparison (DWLOCs) are calculated and used as a point of comparison against the model estimates of a pesticide's concentration in water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food, and from residential uses. Since DWLOCs address total aggregate exposure to ethametsulfuron-methyl they are further discussed in the aggregate risk sections below. Based on the PRZM/EXAMS and SCI-GROW models the estimated EECs of ethametsulfuron-methyl in surface water and ground water, respectively, for chronic exposures are estimated to be 0.3 parts per billion (ppb) for surface water and 0.1 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). Ethametsulfuron-methyl is not registered for use on any sites that would result in residential exposure. 4. 
                    *Cumulative exposure to substances with a common mechanism of toxicity*. Section 408(b)(2)(D)(v) requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider “available information” concerning the cumulative effects of a particular pesticide's residues and “other substances that have a common mechanism of toxicity.” EPA does not have, at this time, available data to determine whether ethametsulfuron-methyl has a common mechanism of toxicity with other substances or how to include this pesticide in a cumulative risk assessment. Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, ethametsulfuron-methyl 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 ethametsulfuron-methyl has a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see the final rule for Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997). C. Safety Factor for Infants and Children 1. 
                    *Safety factor for infants and children*
                    —i. 
                    *In general*. FFDCA section 408 provides that EPA shall apply an additional tenfold margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the data base 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 margin of exposure (MOE) analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. ii. 
                    *Developmental toxicity studies*. EPA has determined that there is adequate information about prenatal developmental toxicity to conclude that ethametsulfuron-methyl does not pose a 
                    ( print page 57970)
                    risk of increased sensitivity due to 
                    *in utero*
                    exposure. iii. 
                    *Reproductive toxicity study*. There are adequate data for EPA to conclude that there is no indication of increased susceptibility of reproductive toxicity. iv. 
                    *Prenatal and postnatal sensitivity.*
                     EPA considers the toxicology data base to be complete and has concluded that there is no indication of prenatal and postnatal sensitivity in rats and rabbits. v. 
                    *Conclusion*. There is a complete toxicity data base for ethametsulfuron-methyl and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. Given that EPA considers that the toxicology data base for ethametsulfuron-methyl is complete. There is no indication of increased susceptibility of rat or rabbit fetuses to 
                    *in utero*
                     and or postnatal exposure in the developmental and reproductive toxicity data. Unrefined dietary exposure estimates are protective since they will exaggerate dietary exposure estimates; and there are currently no registered residential uses for ethametsulfuron-methyl, and therefore, non-dietary exposure to infants and children is not expected. These factors led EPA to conclude that the special 10X safety factor for infants and children should be removed to 1X. D. Aggregate Risks and Determination of Safety To estimate total aggregate exposure to a pesticide from food, drinking water, and residential uses, the Agency calculates DWLOCs which are used as a point of comparison against the model estimates of a pesticide's concentration in water (EECs). DWLOC values are not regulatory standards for drinking water. DWLOCs 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. In calculating a DWLOC, the Agency determines how much of the acceptable exposure (i.e., the PAD) is available for exposure through drinking water (e.g., allowable chronic water exposure (mg/kg/day)= cPAD - (average food + chronic non-dietary, non-occupational exposure)). This allowable exposure through drinking water is used to calculate a DWLOC. A DWLOC will vary depending on the toxic endpoint, drinking water consumption, and body weights. Default body weights and consumption values as used by the US EPA Office of Water are used to calculate DWLOCs: 2 liters (L)/70 kilograms (kg) (adult male), 2L/60 kg (adult female), and 1L/10 kg (child). Default body weights and drinking water consumption values vary on an individual basis. This variation will be taken into account in more refined screening-level and quantitative drinking water exposure assessments. Different populations will have different DWLOCs. Generally, a DWLOC is calculated for each type of risk assessment used: acute, short-term, intermediate-term, chronic, and cancer. When EECs for surface water and ground water are less than the calculated DWLOCs, OPP concludes with reasonable certainty that exposures to ethametsulfuron-methyl in drinking water (when considered along with other sources of exposure for which OPP has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. Because OPP considers the aggregate risk resulting from multiple exposure pathways associated with pesticide's uses, levels of comparison in drinking water may vary as those uses change. If new uses are added in the future, OPP will reassess the potential impacts of ethametsulfuron- methyl on drinking water as a part of the aggregate risk assessment process. 1. 
                    *Acute risk*. An aggregate acute risk assessment was not conducted since a dose and endpoint were not selected because toxicological effects attributable to a single dose (exposure) were not available from the oral toxicology studies, including developmental toxicity studies in rats and rabbits. 2. 
                    *Chronic risk*. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to ethametsulfuron-methyl from food will utilize 0.0%% of the cPAD for the U.S. population and all other sub populations. There are no residential uses for ethametsulfuron-methyl that result in chronic residential exposure to ethametsulfuron-methyl. In addition, despite the potential for chronic dietary exposure to ethametsulfuron-methyl in drinking water, after calculating the DWLOCs and comparing them to conservative model estimated environmental concentrations of ethametsulfuron-methyl in surface and ground water, EPA does not expect the aggregate exposure to exceed 100%% of the cPAD, as shown in the following Table 2. **Table 2.—Aggregate Risk Assessment for Chronic (Non-Cancer) Exposure to Ethametsulfuron-methyl**

                    *Short-term risk*. Short-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Ethametsulfuron-methyl is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which were previously addressed. 4. 
                    *Intermediate-term risk*. 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). Ethametsulfuron-methyl is not registered for use on any sites that would result in residential exposure. Therefore, the aggregate risk is the sum of the risk from food and water, which were previously addressed. 5. 
                    *Aggregate cancer risk for U.S. population*. No evidence of chronic toxicity or carcinogenicity was seen in mice and rats; however, the dose levels tested in these studies were determined to be inadequate. However, it is noted that other sulfonylurea herbicides do not show evidence of carcinogenicity or mutagenicity. Therefore a quantitative risk assessment is not warranted. 6. 
                    *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 
                    ( print page 57971)
                    from aggregate exposure to ethametsulfuron-methyl residues. V. Other Considerations A. Analytical Enforcement Methodology The manufacturer of ethametsulfuron-methyl has submitted a proposed enforcement method to EPA (MRID # 42022113). B. International Residue Limits No Codex, Canadian, or Mexican maximum residue level's have been established for ethametsulfuron-methyl. VI. Conclusion Therefore, the tolerance is established for ethametsulfuron-methyl, in or on canola at 0.02 ppm. VII. Objections and Hearing Requests Under section 408(g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA of 1996, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) provides essentially the same process for persons to “object” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d), as was provided in the old FFDCA sections 408 and 409. However, the period for filing objections is now 60 days, rather than 30 days. A. What Do I Need to Do to File an Objection or Request a Hearing? You must file your objection or request a hearing on this regulation in accordance with the instructions provided in this unit and in 40 CFR part 178. To ensure proper receipt by EPA, you must identify docket control number OPP-301048 in the subject line on the first page of your submission. All requests must be in writing, and must be mailed or delivered to the Hearing Clerk on or before November 27, 2000. 1.
                    *Filing the request*. Your objection must specify the specific provisions in the regulation that you object to, and the grounds for the objections (40 CFR 178.25). If a hearing is requested, the objections must include a statement of the factual issues(s) on which a hearing is requested, the requestor's contentions on such issues, and a summary of any evidence relied upon by the objector (40 CFR 178.27). Information submitted in connection with an objection or hearing request may be claimed confidential by marking any part or all of that information as CBI. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. A copy of the information that does not contain CBI must be submitted for inclusion in the public record. Information not marked confidential may be disclosed publicly by EPA without prior notice. Mail your written request to: Office of the Hearing Clerk (1900), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. You may also deliver your request to the Office of the Hearing Clerk in Rm. C400, Waterside Mall, 401 M St., SW., Washington, DC 20460. The Office of the Hearing Clerk is open from 8 a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The telephone number for the Office of the Hearing Clerk is (202) 260-4865. 2. 
                    *Tolerance fee payment*. If you file an objection or request a hearing, you must also pay the fee prescribed by 40 CFR 180.33(i) or request a waiver of that fee pursuant to 40 CFR 180.33(m). You must mail the fee to: EPA Headquarters Accounting Operations Branch, Office of Pesticide Programs, P.O. Box 360277M, Pittsburgh, PA 15251. Please identify the fee submission by labeling it “Tolerance Petition Fees.” EPA is authorized to waive any fee requirement “when in the judgement of the Administrator such a waiver or refund is equitable and not contrary to the purpose of this subsection.” For additional information regarding the waiver of these fees, you may contact James Tompkins by phone at (703) 305-5697, by e-mail at tompkins.jim@epa.gov, or by mailing a request for information to Mr. Tompkins at Registration Division (7505C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. If you would like to request a waiver of the tolerance objection fees, you must mail your request for such a waiver to: James Hollins, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. 3. 
                    *Copies for the Docket*. In addition to filing an objection or hearing request with the Hearing Clerk as described in Unit VII.A., you should also send a copy of your request to the PIRIB for its inclusion in the official record that is described in Unit I.B.2. Mail your copies, identified by the docket control number OPP-301048, to: Public Information and Records Integrity Branch, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. In person or by courier, bring a copy to the location of the PIRIB described in Unit I.B.2. You may also send an electronic copy of your request via e-mail to: opp-docket@epa.gov. Please use an ASCII file format and avoid the use of special characters and any form of encryption. Copies of electronic objections and hearing requests will also be accepted on disks in WordPerfect 6.1/8.0 file format or ASCII file format. Do not include any CBI in your electronic copy. You may also submit an electronic copy of your request at many Federal Depository Libraries. B. When Will the Agency Grant a Request for a Hearing? A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32). VIII. Regulatory Assessment Requirements This final rule establishes a time limited tolerance under FFDCA section 408. 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). 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 prior consultation as specified by Executive Order 13084, entitled 
                    *Consultation and Coordination with Indian Tribal Governments*
                     (63 FR 27655, May 19, 1998); special considerations as required by Executive Order 12898, entitled 
                    *Federal Actions to Address Environmental Justice in Minority Populations and Low- Income Populations*
                     (59 FR 7629, February 16, 1994); or require OMB review or any 
                    ( print page 57972)
                    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 petition under FFDCA section 408, such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 
                    *et seq.*) do not apply. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled 
                    *Federalism*
                     (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). IX. Submission to Congress and the Comptroller General The Congressional Review Act, 5 U.S.C. 801 
                    *et seq.*, as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of this final rule in the 
                    **Federal Register**
                    . This final rule is not a “major rule” as defined by 5 U.S.C. 804(2). List of Subjects in 40 CFR Part 180 Environmental protection
