AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of the biochemical pesticide 6-benzyladenine on apples and pistachios when applied/used in accordance with the Experimental Use Permit 73049-EUP-2. Valent BioSciences Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting the temporary tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of 6-benzyladenine. The temporary tolerance exemption will expire on January 31, 2005.

DATES:

This regulation is effective February 5, 2003. Objections and requests for hearings, identified by docket ID number OPP-2002-0308, must be received by EPA on or before April 7, 2003.

ADDRESSES:

Written objections and hearing requests may be submitted electronically, by mail, or through hand delivery/courier. Follow the detailed instructions as provided in Unit VIII. of the SUPPLEMENTARY INFORMATION.

II. Background and Statutory Findings

In the Federal Register of March 28, 2002 (67 FR 14948) (FRL-6828-9), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), announcing the filing of a pesticide tolerance petition (PP 2G6378) Start Printed Page 5836by Valent BioSciences Corporation, 870 Technology Way, Suite 100, Libertyville, IL 60048. This notice included a summary of the petition prepared by the petitioner Valent BioSciences Corporation. There were no comments received in response to the notice of filing.

The petition requested that 40 CFR part 180 be amended to expand the existing tolerance exemption by establishing a temporary exemption from the requirement of a tolerance for residues of 6-benzyladenine.

Section 408(c)(2)(A)(i) of the FFDCA allows EPA to establish an exemption from the requirement for a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the exemption is “safe.” Section 408(c)(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....” Additionally, section 408(b)(2)(D) of the FFDCA requires that 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 performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. First, EPA determines the toxicity of pesticides. Second, EPA examines exposure to the pesticide through food, drinking water, and through other exposures that occur as a result of pesticide use in residential settings.

III. Toxicological Profile

Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action and considered its validity, completeness and reliability and the relationship of this information 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 toxicological profile for 6-benzyladenine has been previously published by the Agency in the N6-Benzyladenine (synonymous with the subject active ingredient, 6-benzyladenine) Reregistration Eligibility Decision (RED) document of June 1994 (Ref. 1). The summarized values and categories for the various studies for the technical active ingredient are presented here.

1. Acute toxicity. Toxicity Category III was assigned to the acute oral toxicity study in the rat (LD50 = 1.3 grams/kilogram (g/kg)), and in the eye irritation study in the rabbit (moderate irritant). Toxicity Category IV was assigned to the acute dermal toxicity study in the rabbit (LD50> 5 g/kg), the acute inhalation toxicity study in the rat (LC50 = 5.2 milligrams/liter (mg/L)), and in the dermal irritation study in the rabbit (slight irritant). Additionally, from a dermal sensitization study in the guinea pig, it was determined that N6-benzyladenine is not a dermal sensitizer.

2. Genotoxicity. From three mutagenicity studies (Ames test, mouse micronucleus assay, and unscheduled DNA synthesis assay in the rat), it was determined that N6-benzyladenine is not mutagenic.

3. Developmental toxicity. The no observed adverse effect levels (NOAEL) and the lowest observed adverse effect levels (LOAEL) for maternal and developmental toxicity in rats, respectively, were found to be 50 and 175 mg/kg of body weight (bwt)/day, respectively.

4. Subchronic toxicity. For rats of both sexes, the NOAEL was approximately 111 mg/kg of bwt/day and the LOAEL was approximately 304 mg/kg of bwt/day.

IV. Aggregate Exposures

In examining aggregate exposure, section 408 of the FFDCA directs EPA to consider available information concerning exposures from the pesticide residue in food and all other non-occupational exposures, including drinking water from ground water or surface water and exposure through pesticide use in gardens, lawns, or buildings (residential and other indoor uses).

A. Dietary Exposure

1. Food. Apple and pistachio field trials performed in support of the temporary tolerance exemption request and the associated experimental use permit yielded acceptable magnitude of the residue data (Ref. 2). Residues were below the limit of quantitation (LOQ) for pistachios treated with a total of 60 g of active ingredient (a.i.) per acre. In apples, residues of 6-benzyladenine were consistently near the LOQ. However, residues did not increase in processed commodities (relative to the levels on the raw commodity), and were below the LOQ. Thus, the apple field data are adequate to support the temporary tolerance exemption petition and experimental program to apply ≤182 grams of active ingredient per acre per season. Also, because application precedes harvest by 2 months for pistachio and by approximately 2.5 months for apple, the potential for dietary exposure is reduced.

Due to the low anticipated dietary intake of 6-benzyladenine residues relative to the chronic and acute population adjusted doses (see Unit VI, below), and the fact that actual exposure will probably be considerably less because the dietary exposure analysis was based on worst-case assumptions, it is highly unlikely that the proposed new uses of 6-benzyladenine on apples and pistachios will result in adverse effects to human health.

2. Drinking water exposure. The proposed uses on apples and pistachios are not expected to add potential exposure to drinking water. Soil leaching studies have suggested that 6-benzyladenine is relatively immobile (Ref. 3), absorbing to sediment. Residues reaching surface waters from field runoff should quickly absorb to sediment particles and be partitioned from the water column. 6-Benzyladenine also has low solubility in water, 76 ± 2 mg/L at 20° C (Ref. 2), and detections in ground water are not expected. Together, these data indicate that residues are not expected in drinking water.

B. Other Non-Occupational Exposure

The potential for non-dietary exposure to 6-benzyladenine residues for the general population, including infants and children, is unlikely because the uses are limited to experimental applications in apple and pistachio orchards. Because 6-benzyladenine is a naturally occurring cytokinin plant regulator (Ref. 4, 5, 6, 7, and 8), it is a normal part of the human diet. The proposed experimental use rates are well below the toxicity NOAELs. The residues indicate dietary exposures that are 0.03% and 0.01% of the chronic and acute population adjusted doses, respectively. Therefore, while there exists a great likelihood of prior exposure for most, if not all, individuals to 6-benzyladenine, any increased exposure due to the proposed Start Printed Page 5837experimental product would be negligible due to the lack of residue in comparison with the toxicity NOAELs.

V. Cumulative Effects

The Agency has considered the cumulative effects of 6-benzyladenine and other substances in relation to a common mechanism of toxicity. These considerations include the possible cumulative effects of such residues on infants and children. Based on the available information and data for 6-benzyladenine, no mammalian toxicity is expected at the proposed experimental use rates. Therefore, no cumulative effects are expected.

VI. Determination of Safety for U.S. Population, Infants and Children

1. U. S. population. The analysis estimated that the chronic exposures for the overall U.S. population was 0.000014 mg/kg/day (0.03% of the chronic population adjusted dose (cPAD)). The acute dietary estimated exposure was 0.000069 mg/kg/day (0.01% of the acute population adjusted dose (aPAD)) for the overall U.S. population. Critical exposure commodity analysis showed that apple juice contributed the most to dietary exposure for the overall population. Due to the low anticipated dietary intake of 6-benzyladenine residues relative to the chronic and acute population adjusted doses, and the fact that actual exposure will probably be considerably less because the dietary exposure analysis was made based on worst-case assumptions, it is likely that the proposed new uses of 6-benzyladenine on apples and pistachios will not result in adverse effects to human health.

2. Infants and children. The analysis estimated that the chronic exposures for the most highly exposed subgroup, non-nursing infants, was 0.000085 mg/kg/day (0.2% of the cPAD). The acute dietary estimated exposure was 0.000361 mg/kg/day (0.07% of aPAD) for the most highly exposed subgroup, non-nursing infants. Critical exposure commodity analysis showed that apple juice contributed the most to dietary exposure for all infants. Due to the low anticipated dietary intake of 6-benzyladenine residues relative to the chronic and acute PAD, and the fact that actual exposure will probably be considerably less because the dietary exposure analysis was made based on worst-case assumptions, it is likely that the proposed new uses of 6-benzyladenine on apples and pistachios will not result in adverse effects to human health.

VII. Other Considerations

A. Endocrine Disruptors

EPA is required under the FFDCA as amended by FQPA to develop a screening program to determine whether certain substances (including all pesticide active and other ingredients) “may have an effect in humans that is similar to an effect produced by a naturally occurring estrogen, or other such endocrine effects as the Administrator may designate.” Following the recommendations of its Endocrine Disruptor Screening and Testing Advisory Committee (EDSTAC), EPA determined that there is no scientific basis for including, as part of the program, the androgen and thyroid hormone systems in addition to the estrogen hormone system. EPA also adopted EDSTAC's recommendation that the program include evaluations of potential effects in wildlife. For pesticide chemicals, EPA will use FIFRA and, to the extent that effects in wildlife may help determine whether a substance may have an effect in humans, FFDCA authority to require wildlife evaluations. As the science develops and resources allow, screening of additional hormone systems may be added to the Endocrine Disruptor Screening Program (EDSP). When the appropriate screening and/or testing protocols being considered under the Agency's EDSP have been developed, 6-benzyladenine may be subjected to additional screening and/or testing to better characterize effects related to endocrine disruption.

Based on available data, no endocrine system-related effects have been identified with consumption of 6-benzyladenine. To date, there is no evidence to suggest that 6-benzyladenine affects the immune system, functions in a manner similar to any known hormone, or that it acts as an endocrine disruptor.

B. Analytical Method

The Agency is establishing a temporary exemption from the requirement of a tolerance for the reasons stated above. For the same reasons, the Agency has concluded that an analytical method is not required for enforcement purposes for 6-benzyladenine.

C. Codex Maximum Residue Level

Currently, there are no Codex, Canadian or Mexican maximum residue levels for residues of 6-benzyladenine in/on apples or pistachios.

VIII. Conclusions

Based on the toxicology information submitted and reviewed previously, and summarized in the June 1994 N6-Benzyladenine RED (Ref. 1), there is a reasonable certainty that no harm will result from aggregate exposure of residues of 6-benzyladenine to the U.S. population, including infants and children, under reasonably foreseeable circumstances, when the biochemical pesticide is used in accordance with good agricultural practices under the conditions of the 2-year experimental program. This includes all anticipated dietary exposures and all other exposures for which there is reliable information. The Agency has arrived at this conclusion based on the data submitted previously and summarized in the RED, as well as that data submitted to support the temporary tolerance exemption and Experimental Use Permit applications, demonstrating negligible dietary exposure in comparison with the toxicity NOAELs. As a result, EPA establishes a temporary exemption from the tolerance requirements pursuant to FFDCA 408(c) and (d) for residues of 6-benzyladenine in or on apples and pistachios.

IX. 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, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of the 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), as was provided in the old sections 408 and 409 of the FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

XI. Statuatory and Executive Order Review

This final rule establishes an exemption from the tolerance requirement under section 408(d) of the 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, 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 Start Printed Page 583912(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 the FFDCA, such as the exemption in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of the FFDCA. For these same reasons, the Agency has determined that this rule does not have any “tribal implications” as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive Order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.

XII. 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).
