II. Background and Statutory Findings In the Federal Register of September 24, 1997 ( 62 FR 49979) ( FRL   5745   8), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U. S. C. 346a, as amended by the FQPA of 1996 ( Public Law 104   170), announcing the filing of a pesticide petition PP 4F4391 by DuPont Agricultural Products, Wilmington, DE. This notice included a summary of the petition prepared by DuPont Agricultural Products, the registrant. There were no comments received in response to the notice of filing. The petition requested that 40 CFR 180.487 be amended by establishing a tolerance for residues of the herbicide pyrithiobac sodium, ( sodium 2 chloro 6 [( 4,6 dimethoxypyrimidin 2 yl) thio] benzoate), in or on cotton, undelinted seed at 0.02 parts per million ( ppm) and cotton gin byproducts at 0.1 ppm. The Registrant subsequently amended the petition by VerDate 0ct< 31> 2002 14: 33 Dec 03, 2002 Jkt 200001 PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 E:\ FR\ FM\ 04DER1. SGM 04DER1 72105 Federal Register / Vol. 67, No. 233 / Wednesday, December 4, 2002 / Rules and Regulations increasing the tolerance request for cotton gin byproducts to 0.15 ppm. 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. . . .'' 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 November 26, 1997, ( 62 FR 62961) ( FRL   5754   7).

III. Aggregate Risk Assessment and Determination of Safety Consistent with section 408( b)( 2)( D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure, consistent with section 408( b)( 2), for a tolerance for residues of pyrithiobac sodium on cotton, undelinted seed at 0.02 ppm and cotton gin byproducts at 0.15 ppm. EPA's assessment of exposures and risks associated with establishing the tolerance follows.

A. Toxicological Profile EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. The nature of the toxic effects caused by pyrithiobac sodium are discussed below. This discussion refers to the no observed effect level ( NOEL) and the lowest observed effect level ( LOEL) from the toxicity studies reviewed rather than the no observed adverse effect level ( NOAEL) and the lowest observed adverse effect level ( LOAEL) because the toxicity studies for pyrithiobac sodium were reviewed prior to adoption in 1998 of the NOAEL/ LOAEL terminology by EPA's Office of Pesticide Programs ( OPP) and its Health Effects Division ( HED). At the time of the switch to the revised terminology, HED noted that the new terminology was unlikely to have any substantive effect on its hazard evaluations: `` In a practical sense, the terms NOEL and NOAEL have been used interchangeably in OPP. As a general rule, OPP would consider as appropriate for hazard identification and risk assessment only those effects which are adverse or potentially adverse. This inclusion of the term NOAEL should not change any of our hazard endpoints for regulation but add to the quality of the risk assessment.'' HED Standard Operating Procedure ( SOP) 98.3 1. A rat acute oral study with a LD50 of 3,300 milligrams/ kilogram ( mg/ kg) for males and a LD50 of 3,200 mg/ kg for females. 2. A 90   day rat feeding study with a NOAEL of 50 parts per million ( ppm) ( 3.25 mg/ kg/ day for males and 4.14 mg/ kg/ day for females) and a LOAEL of 500 ppm ( 31.8 mg/ kg/ day for males and 40.5 mg/ kg/ day for females based on decrease body weight gains and increased rate of hepatic beta oxidation in males. 3. A 90   day mouse feeding study with a NOAEL of 500 ppm ( 83.1 mg/ kg/ day for males and 112 mg/ kg/ day for females) and a LOAEL of 1,500 ppm ( 263 mg/ kg/ day for males and 384 mg/ kg/ day for females) based on increased liver weight and an increased incidence of hepatocellular hypertrophy in males and decreased neutrophil count in females. 4. A 3   month dog feeding study with a NOAEL of 5,000 ppm ( 165 mg/ kg/ day) and a LOAEL of 20,000 ppm ( 626 mg/ kg/ day), based on decrease red blood cell count, hemoglobin, and hematocrit in females and increased liver weight in both sexes. 5.

A 2 generation reproduction study in rats with a NOAEL for maternal toxicity of 1,500 ppm ( 103 mg/ kg/ day) and a maternal LOAEL of 7,500 ppm ( 508 mg/ kg/ day), based on decreased body weight, body weight gain and food efficiency. The NOAEL for paternal toxicity is 1,500 ppm ( 86 mg/ kg/ day), while the LOAEL is 7,500 ppm ( 439 mg/ kg/ day), based on decreased body weight, body weight gain and food efficiency. The NOAEL for reproductive effects can be set at 7,500 ppm ( 508 mg/ kg/ day), the LOAEL at 20,000 ppm ( 1,551 mg/ kg/ day), based on decreased pup body weight. The NOAEL for effects on offspring is 7,500 ppm ( 508 mg/ kg/ day), and the LOAEL at 20,000 ppm ( 1,551 mg/ kg/ day), based on decreased pup body weight. 11. A 13   day dosing ( gestation days 7   19) developmental toxicity study in rabbits with a maternal NOAEL of 300 mg/ kg and a maternal LOAEL of 1,000 mg/ kg based on deaths, decreased body weight gain and feed consumption, and an increase in early resorptions. There is developmental toxicity observed at 1,000 mg/ kg based on decreased fetal body weights. 12. A 10   day dosing ( gestation days 7   16) developmental toxicity study in rats wth a maternal NOAEL of 200 mg/ kg and maternal LOAEL of 600 mg/ kg due to increased incidence of peritoneal staining. The developmental NOAEL is 600 mg/ kg and the developmental LOAEL is 1,800 mg/ kg based on the increased incidence of skeletal variations. 13. No evidence of gene mutation was observed in a test for induction of forward mutations at the hypoxanthine guanine phophoribosyl transferase ( HGPRT) locus in Chinese hamster ovary cells. No evidence was observed for inducing reverse gene mutation in two independent assays with Salmonella typhimurium with and without mammalian metabolic activation. Pyrithiobac sodium was negative for the induction of micronuclei in the bone marrow cells of mice, and negative for induction of unscheduled DNA synthesis in rat primary hepatocytes. Pyrithiobac sodium was positive for inducing chromosome aberrations assay in human lymphocytes. 14. A rat metabolism study showed that radio labeled pyrithiobac sodium is excreted in urine and feces with > 90% being eliminated within 48 hours. A sex difference was observed in the excretion and biotransformation. Females excreted a greater amount of the radiolabel in the urine than males following all regimens, with a corresponding lower amount being eliminated in the feces compared to the males.

B. Toxicological Endpoints The dose at which the NOAEL from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern ( LOC). However, the LOAEL at which 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 intra species 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 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) = NOEL/ 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 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 for pyrithiobac sodium used for human risk assessment is as follows: 1. Acute toxicity. EPA has concluded that no endpoint exists to suggest any evidence of significant toxicity from 1   day or single event exposure. 2. Short term and intermediate term toxicity. EPA has concluded that available evidence does not indicate any evidence of significant toxicity from short term and intermediate term exposure. 3. Chronic toxicity. EPA has established the RfD for pyrithiobac sodium at 0.587 mg/ kg/ day. This RfD is based on the systemic NOAEL of 58.7 mg/ kg/ day for males in the rat chronic feeding study with a 100 fold safety factor to account for interspecies extrapolation and intraspecies variability. 4. Carcinogenicity. EPA has concluded that the available data provide limited evidence of the carcinogenicity of pyrithiobac sodium in mice and rats and has classified pyrithiobac sodium as a Group C ( possible human carcinogen with limited evidence of carcinogenicity in animals) in accordance with Agency guidelines, published in the Federal Register of ( September 24, 1986, 51 FR 33992) and recommended that for the purpose of risk characterization a low dose extrapolation model should be applied to the experimental animal tumor data for quantification for human risk ( Q1*). This decision was based on liver adenomas, carcinomas and combined adenoma/ carcinomas in the male mouse and rare kidney tubular adenomas, carcinomas and combined adenoma/ carcinomas in male rats. The unit risk, Q1* ( mg/ kg/ day) 1, of pyrithiobac sodium is 1.05 x 10   3 ( mg/ kg/ day) 1 in human equivalents based on male kidney tumors.

C. Exposure Assessment 1. Dietary exposure from food and feed uses. Permanent tolerances have been requested to replace the time limited tolerance in/ on cottonseed 40 CFR 180.487 at 0.02 ppm, and a new tolerance for the residues of pyrithiobac sodium, in or on cotton gin byproducts at 0.1 ppm. The requested tolerance for cotton gin byproducts has been amended to 0.15 ppm based on the results of the submitted field residue trials, and cottonseed was changed to cotton, undelinted seed. Processing studies for cotton have shown that VerDate 0ct< 31> 2002 14: 33 Dec 03, 2002 Jkt 200001 PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 E:\ FR\ FM\ 04DER1. SGM 04DER1 72107 Federal Register / Vol. 67, No. 233 / Wednesday, December 4, 2002 / Rules and Regulations pyrithiobac sodium does not concentrate in cottonseed processed food/ feed commodities. No requested tolerances were necessary for meat, milk, and eggs because detectible residues are not expected in these commodities from this use on cotton. Risk assessments were conducted by EPA to assess dietary exposures from pyrithiobac sodium in food as follows: i. Acute exposure. Acute dietary risk assessments are performed for a fooduse pesticide if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1   day or single exposure. EPA has concluded that no endpoint exists to suggest any evidence of significant toxicity from one day or single event exposure; therefore, an acute exposure assessment is not applicable. 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 Department of Argiculture ( USDA) 1989   1992 nationwide Continuing Surveys of Food Intake by Individuals ( CSFII) and accumulated exposure to the chemical for each commodity. EPA assumed that all commodities for which tolerances exist and all cotton food commodities had pyrithiobac sodium residues at the appropriate tolerance level. iii. Cancer. The cancer exposure assessment relied upon the same data and assumptions as the chronic exposure assessment. iv. Anticipated residue and percent crop treated ( PCT) information. Tolerance level residues and treatment of 100% of the crop was assumed. Anticipated residues and PCT information was not used. 2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for pyrithiobac sodium 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 pyrithiobac sodium. The Agency uses the GENEEC or the PRZM/ EXAMS to estimate pesticide concentrations in surface water and SCIGROW 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 highend 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 ( PC) area factor as an adjustment to account for the maximum PC 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 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 pyrithiobac sodium they are further discussed in the aggregate risk sections in Unit E. Based on the GENEEC and SCI GROW models the EECs of pyrithiobac sodium for chronic exposures are estimated to be 7.76 parts per billion ( ppb) for surface water and 0.778 ppb for ground water. 3. From non dietary exposure. The term `` residential exposure'' is used in this document to refer to nonoccupational non dietary exposure ( e. g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Pyrithiobac sodium 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 pyrithiobac sodium 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, pyrithiobac sodium 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 pyrithiobac sodium 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 ( November 26, 1997, 62 FR 62961).

D. Safety Factor for Infants and Children 1. In general. FFDCA section 408 provides that EPA shall apply an additional tenfold margin of safety for infants and children in the case of threshold effects to account for pre natal and post natal 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 MOE analysis or through using uncertainty ( safety) factors in calculating a dose level that poses no appreciable risk to humans. 2. Pre natal and post natal sensitivity. In a preliminary review, EPA concluded that data do not indicate that there is a significant potential for reproductive or developmental effects from pyrithiobac sodium as tested. 3. Conclusion. There is a complete toxicity data base for pyrithiobac sodium and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. Pyrithiobac sodium has not been formally reviewed by the Agency regarding the need to retain the additional 10X safety factor for the protection of infants and children. Thus, despite the completeness of the database and the lack of any indication of significant potential for reproductive or developmental effects, EPA has retained the additional 10X safety factor until a full review can be completed.

SGM 04DER1 72108 Federal Register / Vol. 67, No. 233 / Wednesday, December 4, 2002 / Rules and Regulations cPAD for pyrithiobac sodium of 0.0587 mg/ kg/ day.

E. 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 + residential 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 EPA Office of Water are used to calculate DWLOCs: 2L/ 70 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, EPA concludes with reasonable certainty that exposures to the pesticide in drinking water ( when considered along with other sources of exposure for which EPA 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 a pesticide's uses, levels of comparison in drinking water may vary as those uses change. If new uses are added in the future, EPA will reassess the potential impacts of residues of the pesticide in drinking water as a part of the aggregate risk assessment process. Pyrithiobac sodium 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. 1. Acute risk. EPA has concluded that no endpoint exists to suggest any evidence of significant toxicity from acute exposures from the use of pyrithiobac sodium on cotton. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to pyrithiobac sodium from food and water will utilize less than 0.2% of the cPAD for the U. S. population, and less than 0.2% of the cPAD for children 1 to 6 years at greatest exposure to both food and water. There are no residential uses for pyrithiobac sodium that result in chronic residential exposure to pyrithiobac sodium. EPA generally has no concern for exposures below 100% of the cPAD because the cPAD represents the level at or below which aggregate dietary exposure over a lifetime will not pose appreciable risks to human health. Due to the low exposure for the U. S. population ( less than 0.2%) and for children 1 to 6 years ( less than 0.2%) for both food and water, the calculated DWLOC is approximately equal to the cPAD. 3. Short term risk. EPA has concluded that no endpoint exists to suggest any evidence of significant toxicity from short term exposures from the use of pyrithiobac sodium on cotton. 4. Intermediate term risk. EPA has concluded that no endpoint exists to suggest any evidence of significant toxicity from intermediate term exposures from the use of pyrithiobac sodium on cotton. 5. Aggregate cancer risk for U. S. population. Based on the upper bound potency factor ( Q* 1) of 1.05 x 10   3 ( mg/ kg/ day) 1, the aggregate upper bound lifetime cancer risk from the use of pyrithiobac sodium on cotton from worst case estimates of residues in food and drinking water is 2.3 x 10   7. 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 from aggregate exposure to pyrithiobac sodium residues.

IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology high performance liquid chromotography using ultra violent detection ( HPLC UV) with column switching) is available to enforce the tolerance expression. The method may be requested from: Paul Golden, U. S. Environmental Protection Agency, Office of Pesticide Programs, BEAD, ACB, Environmental Science Center, 701 Mapes Road Fort Meade, MD 20755   5350; Telephone ( 410) 305   2960.

B. International Residue Limits There are no established Codex maximum residue levels ( MRLs) for pyrithiobac sodium on cottonseed. An established Mexican tolerance for pyrithiobac sodium on cottonseed is identical to the U. S. tolerance. Compatibility of tolerance levels is not an issue at this time.

C. Conditions There are no conditions. Adequate residue data has been submitted to support the tolerances established in this Federal Register Notice.

V. Conclusion Therefore, the tolerance is established for residues of pyrithiobac sodium, ( sodium 2 chloro 6[( 4,6 dimethoxypyrimidin 2 yl) thio] benzoate), in or on cotton, undelinted seed at 0.02 ppm and cotton gin byproducts at 0.15 ppm.

VI. Objections and Hearing Requests Under section 408( g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA of 1996, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408( g) provides essentially the same process for persons to `` object'' to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408( d), as was provided in the old FFDCA sections 408 and 409. However, the period for filing objections is now 60 days, rather than 30 days.

You may also submit an electronic copy of your request at many Federal Depository Libraries.

B. When Will the Agency Grant a Request for a Hearing? A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues( s) in the manner sought by the requestor would be adequate to justify the action requested ( 40 CFR 178.32).

VII. Regulatory Assessment Requirements This final rule establishes a tolerance under FFDCA section 408( d) in response to a petition submitted to the Agency. The Office of Management and Budget ( OMB) has exempted these types of actions from review under Executive Order 12866, entitledRegulatory Planning and Review ( 58 FR 51735, October 4, 1993). Because this rule has been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use ( 66 FR 28355, May 22, 2001). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act ( PRA), 44 U. S. C. 3501 et seq., or impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 ( UMRA) ( Public Law 104   4). Nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low Income Populations ( 59 FR 7629, February 16, 1994); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks ( 62 FR 19885, April 23, 1997). This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12( d) of the National Technology Transfer and Advancement Act of 1995 ( NTTAA), Public Law 104   113, section 12( d) ( 15 U. S. C. 272 note). Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408( d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act ( RFA) ( 5 U. S. C. 601 et seq.) do not apply. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism ( 64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure `` meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' `` Policies that have federalism implications'' is defined in the Executive Order to include regulations that have `` substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.'' This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408( n)( 4). For these same reasons, the Agency has determined that this rule does not have VerDate 0ct< 31> 2002 14: 33 Dec 03, 2002 Jkt 200001 PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 E:\ FR\ FM\ 04DER1. SGM 04DER1 72110 Federal Register / Vol. 67, No. 233 / Wednesday, December 4, 2002 / Rules and Regulations 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 andIndian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.

VIII. Submission to Congress and the Comptroller General The Congressional Review Act, 5 U. S. C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U. S. Senate, the U. S. House of Representatives, and the Comptroller General of the United States prior to publication of this final rule in the Federal Register. This final rule is not a `` major rule'' as defined by 5 U. S. C. 804( 2).

SUPPLEMENTARY INFORMATION: Background NAFO has established and maintains conservation measures in its Regulatory Area that include one effort limitation fishery as well as fisheries with total allowable catches ( TACs) and member nation quota allocations. The principal species managed are cod, flounder, redfish, American plaice, halibut, capelin, shrimp, and squid. At the 2002 NAFO Annual Meeting, the United States received fish quota allocations for three NAFO stocks and an effort allocation for one NAFO stock to be fished during 2003. The species, location, and allocation ( in metric tons or effort) of these U. S. fishing opportunities are as follows: ( 1) Redfish NAFO Division 3M 69 mt ( 2) Squid NAFO Subareas 3 & 4 453 mt ( 3) Shrimp NAFO Division 3L 67 mt ( 4) Shrimp NAFO Division 3M 1 vessel/ 100 days Additionally, U. S. vessels may fish any portion of the 7,500 mt TAC of oceanic redfish in NAFO Subarea 2 and Divisions 1F and 3K. This opportunity is available only to members of NAFO that are not members of the North East Atlantic Fisheries Commission, on a first come, first served basis. Allocations are also available to U. S.
