ACTION: Final rule. rmajette on PROD1PC67 with RULES1 AGENCY: SUMMARY: This regulation establishes an increase in tolerances for the sum of the residues of imazethapyr and its metabolites, CL 288511, (2-[4,5-dihydro4-methyl-4-(1-methylethyl)-5-oxo-1Himidazol-2-yl]-5-(1-hydroxyethyl)-3pyridine carboxylic acid), and CL 182704, (5-[1-(beta-Dglucopyranosyloxy)ethyl]-2-[4,5dihydro-4-methyl-4-(1-methylethyl)-5oxo-1H-imidazol-2-yl]-3pyridinecarboxylic acid), applied as its acid or ammonium salt in or on rice grain at 0.3 ppm, rice straw at 0.4 ppm, and imazethapyr and its metabolite, CL 288511 in or on crayfish at 0.15 ppm. BASF Corporation requested the tolerances for rice grain and rice straw under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), because of a requested increase in the use rate of imazethapyr in rice. In addition, this regulation increases the tolerance on crayfish from 0.10 ppm to 0.15 ppm due to exposure of crayfish raised in rice fields to imazethapyr. DATES: This regulation is effective February 8, 2006. Objections and requests for hearings must be received on or before April 10, 2006. ADDRESSES: To submit a written objection or hearing request follow the detailed instructions as provided in Unit VI. of the SUPPLEMENTARY INFORMATION.

A frequently updated electronic version of 40 CFR part 180 is available on E-CFR Beta Site Two at https:// www.gpoaccess.gov/ecfr/. II. Background and Statutory Findings In the Federal Register of June 29, 2005 (70 FR 37392) (FRL–7718–5), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 5F 6947) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research Triangle Park, North Carolina 27709–3528. The petition requested that 40 CFR 180.447 be amended by establishing a tolerance for the sum of the residues of the herbicide Imazethapyr, and its metabolites CL 288511 and CL182704, in or on rice grain at 0.3 parts per million (ppm), and rice straw at 0.4 ppm. That notice included a summary of the petition prepared by BASF Corporation, the registrant. Comments were received on the notice of filing. EPA’s response to these comments is discussed in Unit IV.C. In addition, after completion of the dietary risk analysis for imazethapyr residues on rice, the Agency determined that the tolerance for combined residues for imazethapyr and the metabolite CL 288511 in crayfish needs to be increased from 0.10 ppm to 0.15 ppm. Crayfish are often raised in flooded rice fields, and thus are exposed to residues of pesticides that are applied to rice. Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is ‘‘safe.’’ Section 408(b)(2)(A)(ii) of FFDCA defines ‘‘safe’’ to mean that ‘‘there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.’’ This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section E:\FR\FM\08FER1.SGM 08FER1 Federal Register / Vol. 71, No. 26 / Wednesday, February 8, 2006 / Rules and Regulations 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to ‘‘ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .’’ 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 FFDCA and a complete description of the risk assessment process, see https:// www.epa.gov/fedrgstr/EPA-PEST/1997/ November/Day-26/p30948.htm. III. Aggregate Risk Assessment and Determination of Safety Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure, consistent with section 408(b)(2) of FFDCA, for a tolerances for the sum of the residues of imazethapyr and its metabolites CL 288511 and CL 182704 on rice grain at 0.3 ppm, rice straw at 0.4 ppm, and for the sum of residues of imazethapyr and its metabolite 288511 in crayfish at 0.15 ppm. EPA’s assessment of exposures and risks associated with establishing the tolerance follows. rmajette on PROD1PC67 with RULES1 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 imazethapyr are discussed in Unit III.A. of the final rule that established imazethapyr tolerances in or on rice, crayfish, and meat byproducts of certain cattle (FR notice dated August 29, 2002, 67 FR 55323, FRL–7193–4). B. Toxicological Endpoints For hazards that have a threshold below which there is no appreciable risk, 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 level of concern (LOC). However, the lowest dose at which adverse effects of concern VerDate Aug<31>2005 15:23 Feb 07, 2006 Jkt 208001 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. The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify nonthreshold hazards such as cancer. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk, estimates risk in terms of the probability of occurrence of additional cancer cases. More information can be found on the general principles EPA uses in risk characterization at www.epa.gov/ pesticides. A summary of the toxicological endpoints for imazethapyr used for human risk assessment is discussed in Unit III.B. of the final rule published in the Federal Register of (FR notice dated August 29, 2002, 67 FR 55323). C. Exposure Assessment The Registrant, BASF Corporation, has requested an amended registration to increase the use rate of, 2-[4,5dihydro-4-methyl-4-(1-methylethyl)-5oxo-1H-imidazol-2-yl]-5-ethyl-3pyridine carboxylic acid from 0.125 lbs acid equivalent (ae)/application/acre/ crop season and a 45–day preharvest interval (PHI) to 0.188 lbs ae/ application/acre per crop season and an 85–day PHI. The dietary exposure for all populations continues to be <1% chronic population adjusted dose (cPAD) with the minor changes in tolerances for rice grain and straw, and crayfish established in this Federal Register Notice. The exposure assessment for imazethapyr is discussed in Unit III.C. of the final rule that established the original imazethapyr tolerances in or on rice, crayfish, and meat byproducts of certain cattle (FR notice dated August 29, 2002, 67 FR 55323). In this action, the tolerances for rice grain are increased from 0.2 ppm to 0.3 ppm, for rice straw are increased from 0.15 ppm to 0.4 ppm) and in crayfish are increased from 0.10 ppm to 0.15 ppm. These increases resulted in an increase in dietary exposure for the general population from 0.000393 milligram/kilogram/day (mg/kg/day) to 0.002367 mg/kg/day, which is still much less than 1% of the cPAD of 2.5 mg/kg/day. The highest dietary exposure as a result of the increased tolerances is 0.008824 mg/kg/day for PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 6357 non-nursing infants, which is also less than 1% of the cPAD. (Since dietary exposure for non-nursing infants was not calculated separately in the previous dietary assessment, but was included as part of all infants, there is no meaningful comparison to previous dietary risk exposures.) D. Safety Factor for Infants and Children The safety factors for infants and children for imazethapyr are discussed in Unit III.D. of the final rule that established imazethapyr tolerances in or on rice, crayfish, and meat byproducts of certain cattle (FR notice dated August 29, 2002, 67 FR 55323). E. Aggregate Risks and Determination of Safety The aggregate risks and determination of safety for imazethapyr are discussed in Unit III.E. of the final rule that established imazethapyr tolerances in or on rice, crayfish, and meat byproducts of certain cattle (notice dated August 29, 2002, 67 FR 55323). 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 imazethapyr residues. IV. Other Considerations A. Analytical Enforcement Methodology The enforcement method for use on rice grain and rice straw is Method M3120. This method measures the concentrations of imazethapyr and its metabolites CL 288511 and CL 182704. The method extracts residues with acidic aqueous methanol, and the extract is then eluted through C18, strong anion exchange, and strong cation exchange columns. Residues are quantified via capillary electrophoresis with a UV detector. The enforcement method for use on crayfish is Method 3512. This method quantifies the residues for imazethapyr and its metabolite CL 299511. This method involves extraction of residues using acidic acetone, followed by elution through a C18 column, and residues are quantified using LC/MS analysis. The enforcement methods may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755–5350; telephone number: (410) 305–2905; e-mail address: residuemethods@epa.gov. B. International Residue Limits There are no Codex maximum residue levels established or proposed for residues of imazethapyr on rice. E:\FR\FM\08FER1.SGM 08FER1 6358 Federal Register / Vol. 71, No. 26 / Wednesday, February 8, 2006 / Rules and Regulations C. Response to Comments Public comments were received from B. Sachau. She objected that the several of the proposed tolerances levels, including the level for chicken, are too high. She questions who performed the tests showing these levels are necessary and whether EPA checked the tests. Ms. Sachau also objected to the use of animal testing, and the use of food intake survey data from 1994. Response: EPA requires that petitioners submit data from studies on residue levels in treated crops and in animals that consume treated crops. Such studies are performed according to established protocols and EPA carefully examines the data from the studies after it is submitted. That was done with regard to the tolerance levels for imazethapyr. It is noted that imazethapyr tolerances in chicken are not being increased by this action. EPA has responded to B. Sachau’s generalized comments, in including her generalized objections to animal testing, on numerous previous occasions (see January 7, 2005, 70 FR 1349, 1354, FRL– 7691–4); (October 29, 2004, 69 FR 63083, 63096, FRL–7681–9). As to her claim that food consumption data from 1994 is out of date, EPA would note that the food consumption data relied upon was collected between 1994 and 1998 by the United States Department of Agriculture (USDA) in there (Continuing Survey of Food Intakes by Individuals (CSFII)). Generally, major surveys of consumption patterns have been conducted by the USDA every 5 to 10 years or so. EPA has found that changes between surveys are on the margin and EPA has no reason to believe that there have been significant shifts in food consumption patterns in the last several years. B. Sachau’s comments contained no scientific data or evidence to rebut the Agency’s conclusion that there is a reasonable certainty that no harm will result from aggregate exposure to imazethapyr, including all anticipated dietary exposures and all other exposures for which there is reliable information. rmajette on PROD1PC67 with RULES1 V. Conclusion Therefore, tolerances are established for the sum of the residues of imazethapyr, and its metabolites CL 288511 and CL 182704, in or on rice, grain at 0.3 ppm, and rice, straw at 0.4 ppm and for the sum of the residues of imazethapyr and its metabolite CL 288511 in or on crayfish at 0.15 ppm. VI. Objections and Hearing Requests Under section 408(g) of FFDCA, as amended by FQPA, any person may file VerDate Aug<31>2005 15:23 Feb 07, 2006 Jkt 208001 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 FFDCA by FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of FFDCA 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) of FFDCA, as was provided in the old sections 408 and 409 of FFDCA. 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 ID number EPA–HQ– OPP–2005–0508 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 April 10, 2006. 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 issue(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 (1900L), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460–0001.

Copies of electronic objections and hearing requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format. Do not include any CBI in your electronic copy. You may also submit an electronic copy of your request at many Federal Depository Libraries. B. When Will the Agency Grant a Request for a Hearing? A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issue(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32). VII. Statutory and Executive Order Reviews This final rule establishes a tolerance under section 408(d) of FFDCA in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). Because this 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, E:\FR\FM\08FER1.SGM 08FER1 6359 rmajette on PROD1PC67 with RULES1 Federal Register / Vol. 71, No. 26 / Wednesday, February 8, 2006 / Rules and Regulations 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 section 408(d) of FFDCA, such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply. 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 VerDate Aug<31>2005 15:23 Feb 07, 2006 Jkt 208001 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).

AGENCY: SUMMARY: This regulation establishes tolerances for residues of boscalid, 3pyridinecarboxamide, 2-chloro-N-(4′chloro [1,1′-biphenyl]-2-yl) in or on banana (imported), celery, and spinach. In addition, existing tolerances are being increased on almond hulls. Finally, the existing lettuce exception listed for the indirect or inadvertent residues in vegetables, leafy, group 4, is being revised to include celery and spinach, as well as lettuce. BASF requested the tolerances on almonds and bananas, and Interregional Research Project #4 (IR-4) has proposed group tolerances on vegetable, leafy, except brassica, Group 4 (to include celery and spinach), under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA).

40 CFR Part 180

[EPA-HQ-OPP-2005-0508; FRL-7755-8]


Imazethapyr; Pesticide Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes an increase in tolerances for the 
sum of the residues of imazethapyr and its metabolites, CL 288511, (2-
[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-5-(1-
hydroxyethyl)-3-pyridine carboxylic acid), and CL 182704, (5-[1-(beta-
D-glucopyranosyloxy)ethyl]-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-
oxo-1H-imidazol-2-yl]-3-pyridinecarboxylic acid), applied as its acid 
or ammonium salt in or on rice grain at 0.3 ppm, rice straw at 0.4 ppm, 
and imazethapyr and its metabolite, CL 288511 in or on crayfish at 0.15 
ppm. BASF Corporation requested the tolerances for rice grain and rice 
straw under the Federal Food, Drug, and Cosmetic Act (FFDCA), as 
amended by the Food Quality Protection Act of 1996 (FQPA), because of a 
requested increase in the use rate of imazethapyr in rice. In addition, 
this regulation increases the tolerance on crayfish from 0.10 ppm to 
0.15 ppm due to exposure of crayfish raised in rice fields to 
imazethapyr.

DATES: This regulation is effective February 8, 2006. Objections and 
requests for hearings must be received on or before April 10, 2006.

ADDRESSES: To submit a written objection or hearing request follow the

II. Background and Statutory Findings

    In the Federal Register of June 29, 2005 (70 FR 37392) (FRL-7718-
5), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 5F 
6947) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research 
Triangle Park, North Carolina 27709-3528. The petition requested that 
40 CFR 180.447 be amended by establishing a tolerance for the sum of 
the residues of the herbicide Imazethapyr, and its metabolites CL 
288511 and CL182704, in or on rice grain at 0.3 parts per million 
(ppm), and rice straw at 0.4 ppm. That notice included a summary of the 
petition prepared by BASF Corporation, the registrant. Comments were 
received on the notice of filing. EPA's response to these comments is 
discussed in Unit IV.C.
    In addition, after completion of the dietary risk analysis for 
imazethapyr residues on rice, the Agency determined that the tolerance 
for combined residues for imazethapyr and the metabolite CL 288511 in 
crayfish needs to be increased from 0.10 ppm to 0.15 ppm. Crayfish are 
often raised in flooded rice fields, and thus are exposed to residues 
of pesticides that are applied to rice.
    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section

[[Page 6357]]

408(b)(2)(C) of FFDCA requires EPA to give special consideration to 
exposure of infants and children to the pesticide chemical residue in 
establishing a tolerance and to ``ensure that there is a reasonable 
certainty that no harm will result to infants and children from 
aggregate exposure to the pesticide chemical residue. . . .''
    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 FFDCA and a complete 
description of the risk assessment process, see https://www.epa.gov/
fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.

III. Aggregate Risk Assessment and Determination of Safety

    Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the 
available scientific data and other relevant information in support of 
this action. EPA has sufficient data to assess the hazards of and to 
make a determination on aggregate exposure, consistent with section 
408(b)(2) of FFDCA, for a tolerances for the sum of the residues of 
imazethapyr and its metabolites CL 288511 and CL 182704 on rice grain 
at 0.3 ppm, rice straw at 0.4 ppm, and for the sum of residues of 
imazethapyr and its metabolite 288511 in crayfish 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 imazethapyr are 
discussed in Unit III.A. of the final rule that established imazethapyr 
tolerances in or on rice, crayfish, and meat byproducts of certain 
cattle (FR notice dated August 29, 2002, 67 FR 55323, FRL-7193-4).

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no 
appreciable risk, 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 level of 
concern (LOC). 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.
    The linear default risk methodology (Q*) is the primary method 
currently used by the Agency to quantify non-threshold hazards such as 
cancer. The Q* approach assumes that any amount of exposure will lead 
to some degree of cancer risk, estimates risk in terms of the 
probability of occurrence of additional cancer cases. More information 
can be found on the general principles EPA uses in risk 
characterization at www.epa.gov/pesticides.
    A summary of the toxicological endpoints for imazethapyr used for 
human risk assessment is discussed in Unit III.B. of the final rule 
published in the Federal Register of (FR notice dated August 29, 2002, 
67 FR 55323).

C. Exposure Assessment

    The Registrant, BASF Corporation, has requested an amended 
registration to increase the use rate of, 2-[4,5-dihydro-4-methyl-4-(1-
methylethyl)-5-oxo-1H-imidazol-2-yl]-5-ethyl-3-pyridine carboxylic acid 
from 0.125 lbs acid equivalent (ae)/application/acre/crop season and a 
45-day preharvest interval (PHI) to 0.188 lbs ae/application/acre per 
crop season and an 85-day PHI.
    The dietary exposure for all populations continues to be <1% 
chronic population adjusted dose (cPAD) with the minor changes in 
tolerances for rice grain and straw, and crayfish established in this 
Federal Register Notice. The exposure assessment for imazethapyr is 
discussed in Unit III.C. of the final rule that established the 
original imazethapyr tolerances in or on rice, crayfish, and meat 
byproducts of certain cattle (FR notice dated August 29, 2002, 67 FR 
55323). In this action, the tolerances for rice grain are increased 
from 0.2 ppm to 0.3 ppm, for rice straw are increased from 0.15 ppm to 
0.4 ppm) and in crayfish are increased from 0.10 ppm to 0.15 ppm. These 
increases resulted in an increase in dietary exposure for the general 
population from 0.000393 milligram/kilogram/day (mg/kg/day) to 0.002367 
mg/kg/day, which is still much less than 1% of the cPAD of 2.5 mg/kg/
day. The highest dietary exposure as a result of the increased 
tolerances is 0.008824 mg/kg/day for non-nursing infants, which is also 
less than 1% of the cPAD. (Since dietary exposure for non-nursing 
infants was not calculated separately in the previous dietary 
assessment, but was included as part of all infants, there is no 
meaningful comparison to previous dietary risk exposures.)

D. Safety Factor for Infants and Children

    The safety factors for infants and children for imazethapyr are 
discussed in Unit III.D. of the final rule that established imazethapyr 
tolerances in or on rice, crayfish, and meat byproducts of certain 
cattle (FR notice dated August 29, 2002, 67 FR 55323).

E. Aggregate Risks and Determination of Safety

    The aggregate risks and determination of safety for imazethapyr are 
discussed in Unit III.E. of the final rule that established imazethapyr 
tolerances in or on rice, crayfish, and meat byproducts of certain 
cattle (notice dated August 29, 2002, 67 FR 55323). 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 imazethapyr residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    The enforcement method for use on rice grain and rice straw is 
Method M3120. This method measures the concentrations of imazethapyr 
and its metabolites CL 288511 and CL 182704. The method extracts 
residues with acidic aqueous methanol, and the extract is then eluted 
through C18, strong anion exchange, and strong cation exchange columns. 
Residues are quantified via capillary electrophoresis with a UV 
detector.
    The enforcement method for use on crayfish is Method 3512. This 
method quantifies the residues for imazethapyr and its metabolite CL 
299511. This method involves extraction of residues using acidic 
acetone, followed by elution through a C18 column, and residues are 
quantified using LC/MS analysis. The enforcement methods may be 
requested from: Chief, Analytical Chemistry Branch, Environmental 
Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone 
number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

    There are no Codex maximum residue levels established or proposed 
for residues of imazethapyr on rice.

[[Page 6358]]

C. Response to Comments

    Public comments were received from B. Sachau. She objected that the 
several of the proposed tolerances levels, including the level for 
chicken, are too high. She questions who performed the tests showing 
these levels are necessary and whether EPA checked the tests. Ms. 
Sachau also objected to the use of animal testing, and the use of food 
intake survey data from 1994.
    Response: EPA requires that petitioners submit data from studies on 
residue levels in treated crops and in animals that consume treated 
crops. Such studies are performed according to established protocols 
and EPA carefully examines the data from the studies after it is 
submitted. That was done with regard to the tolerance levels for 
imazethapyr. It is noted that imazethapyr tolerances in chicken are not 
being increased by this action. EPA has responded to B. Sachau's 
generalized comments, in including her generalized objections to animal 
testing, on numerous previous occasions (see January 7, 2005, 70 FR 
1349, 1354, FRL-7691-4); (October 29, 2004, 69 FR 63083, 63096, FRL-
7681-9). As to her claim that food consumption data from 1994 is out of 
date, EPA would note that the food consumption data relied upon was 
collected between 1994 and 1998 by the United States Department of 
Agriculture (USDA) in there (Continuing Survey of Food Intakes by 
Individuals (CSFII)). Generally, major surveys of consumption patterns 
have been conducted by the USDA every 5 to 10 years or so. EPA has 
found that changes between surveys are on the margin and EPA has no 
reason to believe that there have been significant shifts in food 
consumption patterns in the last several years. B. Sachau's comments 
contained no scientific data or evidence to rebut the Agency's 
conclusion that there is a reasonable certainty that no harm will 
result from aggregate exposure to imazethapyr, including all 
anticipated dietary exposures and all other exposures for which there 
is reliable information.

V. Conclusion

    Therefore, tolerances are established for the sum of the residues 
of imazethapyr, and its metabolites CL 288511 and CL 182704, in or on 
rice, grain at 0.3 ppm, and rice, straw at 0.4 ppm and for the sum of 
the residues of imazethapyr and its metabolite CL 288511 in or on 
crayfish at 0.15 ppm.

VI. Objections and Hearing Requests

    Under section 408(g) of FFDCA, as amended by 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 FFDCA by FQPA, EPA 
will continue to use those procedures, with appropriate adjustments, 
until the necessary modifications can be made. The new section 408(g) 
of FFDCA 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) of FFDCA, as was 
provided in the old sections 408 and 409 of FFDCA. 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 ID number EPA-HQ-OPP-2005-0508 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 April 10, 
2006.
    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 issue(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 (1900L), 
Environmental Protection Agency, 1200 Pennsylvania Ave., NW., 
Washington, DC 20460-0001. You may also deliver your request to the 
Office of the Hearing Clerk in Suite 350, 1099 14\th\ St., NW., 
Washington, DC 20005. 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) 564-6255.
    2. Copies for the EPA. In addition to filing an objection or 
hearing request with the Hearing Clerk as described in Unit VI.A., you 
should also send a copy of your request to the PIRIB for its inclusion 
in the official record that is described in ADDRESSES. Mail your 
copies, identified by docket ID number EPA-HQ-OPP-2005-0508, to: Public 
Information and Records Integrity Branch, Information Technology and 
Resource Management Division (7502C), Office of Pesticide Programs, 
Environmental Protection Agency, 1200 Pennsylvania Ave., NW., 
Washington, DC 20460-0001. In person or by courier, bring a copy to the 
location of the PIRIB described in ADDRESSES. 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 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 issue(s) in the manner sought 
by the requestor would be adequate to justify the action requested (40 
CFR 178.32).

VII. Statutory and Executive Order Reviews

    This final rule establishes a tolerance under section 408(d) of 
FFDCA in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled Regulatory Planning and 
Review (58 FR 51735, October 4, 1993). Because this 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,

[[Page 6359]]

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 section 408(d) of FFDCA, such as the tolerance in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.) do not apply. 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 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).
