AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This regulation establishes an exemption from the requirement of a tolerance for residues of 1-Methylcyclopropene (1-MCP) in or on fruits and vegetables when used as a post harvest plant growth regulator, i.e., for the purpose of inhibiting the effects of ethylene. AgroFresh, Inc. (formerly BioTechologies for Horticulture) submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996, requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 1-MCP.

DATES:

This regulation is effective July 26, 2002. Objections and requests for hearings, identified by docket ID number OPP-2002-0142, must be received on or before September 24, 2002.

ADDRESSES:

Written objections and hearing requests may be submitted by mail, electronically, or in person. Please follow the detailed instructions for each method as provided in Unit IX. of the SUPPLEMENTARY INFORMATION.

II. Background and Statutory Findings

In the Federal Register of June 21, 2000 (65 FR 38550) (FRL-6589-5), EPA issued a notice pursuant to section 408(d)(3) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d)(3), as amended by the Food Quality Protection Act (FQPA) (Public Law 104-170), announcing the filing of a pesticide tolerance petition (PP OF6144) by AgroFrech, Inc. (formerly BioTechnologies for Horticulture, Inc.), 100 Independence Mall West, Philadelphia, PA 19106-2399. As required by section 408(d)(2)(A)(i)(I), this notice included a summary of the petition prepared by the petitioner AgroFresh, Inc. There were no comments received in response to the notice of filing.

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 tolerance is “safe.” Section 408(c)(2)(A)(ii) defines “safe” to mean that “there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .” Additionally, section 408(b)(2)(D) 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, Start Printed Page 48797EPA 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 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 end-use product, a white powder, when mixed with water or a buffer solution releases the gas 1-MCP. The active ingredient acts an inhibitor to ethylene, by blocking the attachment of ethylene to tissue, and thus, prolongs the life of the food commodity treated.

Toxicity studies submitted in support of the tolerance exemption petition, and the Agency reviews are compiled in the official record established for this action under the docket ID number OPP-2002-0142.

1. Acute toxicity (MRIDs 444647-04 to 08). 1-MCP exhibits low acute toxicity. It is a category IV biopesticide. The rat oral LD50 is greater than 5,000 milligrams/kilograms (mg/kg), the rabbit dermal LD50 is greater than 2,000 mg/kg and the rat inhalation LC50 is greater than 2.5 milligram/liter (mg/L) (or greater than 1,126 parts per million (ppm) v/v active ingredient in air). No deaths or clinical signs of systemic toxicity were observed following these acute exposures. 1-MCP produces minimal irritation of skin and eyes in rabbits and 1-MCP is not a skin sensitizer. No hypersensitivity incidents were observed following exposure to 1-MCP.

2. Genotoxicity (MRID 444647-09). 1-MCP was not mutagenic when tested as a gas in several short-term in vitro/in vivo assays, including a bacterial reverse mutation assay (Ames test), an in vitro mammalian point mutation assay in Chinese hamster ovary cells, an in vitro cytogenetics assay in human lymphocytes and an in vivo mouse micronucleus assay following inhalation exposure. In addition, 1-MCP is not mutagenic when tested as a suspension in cell media in the Ames test and in the in vitro mouse lymphoma forward mutation assay (MRID 444647-10) and is not mutagenic in the in vivo mouse micronucleus assay (MRID 444747-11) following oral exposure (gavage).

3. Developmental toxicity (MRID 454586-08). 1-MCP produces no developmental toxicity when tested in a standard developmental toxicity study in the rat via inhalation at concentrations up to and including 2.3 mg a.i./L (or 543 mg a.i./kg/day, 6 hr exposure/day). The no observed adverse effect level (NOAEL) for maternal toxicity was 0.24 mg a.i./L (56 mg a.i./kg/day, 6 hr exposure/day).

4. Subchronic toxicity (MRID 456090-01). 1-MCP was tested in a 90-day inhalation study at doses of 0.05, 0.24 and 2.3 mg a.i./kg in the rat. The NOAEL is 0.05 mg a.i./L (equivalent to 9 to 15 mg a.i./kg/day), based on minimal to mild effects on spleen and kidney histopathology at 0.24 mg a.i./L (equivalent to 39 to 66 mg a.i./kg/day). In this study there was no evidence of neurotoxicity, no effects on the respiratory tract and no effects on pathology of any endocrine or reproductive organs up to and including the highest dose tested of 2.3 mg a.i./L (or equivalent to 380 to 640 mg a.i./kg/day).

5. AgroFresh (the applicant) submitted a waiver request for the immune response data requirements based on the current toxicological data submitted on 1-MCP. The review of the 3-month inhalation rat study (mentioned in the previous paragraph) indicates, no effects on thymus weight and no effects on the histopathology of the thymus, bone marrow or spleen that would be attributed to an impact on the immune system were seen. There were no effects on white blood cell differential parameters (including monocytes, lymphocytes, segmented neutrophils or eosinophils) and no basophils were observed which may be indicative of an allergic reaction. The Agency concluded that 1-MCP did not induce dysfunction or inappropriate suppressive responses in components of the immune system. As a result, immune response data requirements were waived.

6. Other. 1-MCP has a mode of action in plants which is a non-persistent and non-toxic mode of action. 1-MCP prevents the natural chemical, ethylene, from binding to ethylene receptors in plants. This mode of action is not relevant in animals, since ethylene receptors are not present in animal tissues.

IV. Aggregate Exposures

In examining aggregate exposure, FFDCA section 408 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. FoodFrom food and feed uses. The primary source for human exposure to 1-MCP will be from ingestion of the following raw food commodities and the processed food commodities derived from: apples, melons, tomatoes, pears, avocadoes, mangoes, papayas, kiwifruit, plums, apricots and persimmons. Studies submitted (MRID 456090-02) showed residues in treated apples to be extremely low (average residue was 0.004 ppm using an exaggerated treatment rate of 1,200 parts per billion (ppb) versus the 1,000 ppb proposed label rate). A worst-case scenario (using the 0.004 ppm average residue concentration found in treated apples and assuming that concentration is present in 100% of the diet regardless of crops treated) indicates that a daily diet of 1.5 kg/day could contain 0.006 mg 1-MCP. For the general population (assuming an average body weight of 60 kg), this would represent a daily intake of 0.0001 mg 1-MCP/kg body weight which is 90,000 to 150,000-fold less than the 9-15 mg/kg NOAEL indicated in the 90-day inhalation study.

Residues in other treated commodities are expected to be similar or even lower since the highest treatment rate is recommended for apples. Processing would be expected to further lower the residue levels in processed food commodities.

2. Drinking water exposure. Since 1-MCP will only be used on post-harvested fruits and vegetables in enclosed storage areas, there is little if any, potential for drinking water exposure.

B. Other Non-Occupational Exposure

The potential for non-dietary exposure to 1-MCP for the general population, is unlikely because potential use sites are commercial, agricultural, and horticultural. 1-MCP is currently registered for indoor, nonfood commercial use on flowers and ornamentals. The Agency has approved that use, based on the data submitted that show little potential for significant non-occupational exposure to the general population.

1. Dermal exposure. 1-MCP will only be sold enclosed in a generator for treatment of raw agricultural commodities. The generator will not release 1-MCP until the applicator has exited the storage area and entrances to the treatment area have been sealed. At Start Printed Page 48798the end of the treatment period, the storage area will be vented before workers are permitted to reenter the area. This label mitigating language would eliminate the potential for dermal exposure to handlers or applicators.

2. Inhalation exposure. As mentioned in the previous paragraph, the use of this product according to the label instructions would result in little, if any, inhalation exposure to handlers or applicators.

V. Cumulative Effects

The Agency has considered the cumulative effects of 1-MCP 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. There is no indication of mammalian toxicity at the maximum doses tested, of this or other products containing 1-MCP.

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

1. U.S. population. There is reasonable certainty that no harm will result from aggregate exposure to residues of 1-MCP to the U.S. population. 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 very low levels of mammalian toxicity (no toxicity at the maximum doses tested, Toxicity Categories III and IV) and the minimum exposure associated with 1-MCP's use.

2. Infants and children. FFDCA section 408 provides that EPA shall apply an additional tenfold margin of exposure (safety) for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the data base unless EPA determines that a different margin of exposure (safety) will be safe for infants and children. Margins of exposure (safety) are often referred to as uncertainty (safety) factors. In this instance, based on all the available information, the Agency concludes that 1-MCP is practically non-toxic to mammals, including infants and children. Thus, there are no threshold effects of concern and, as a result the provision requiring an additional margin of safety does not apply. Further, based on the lack of observed developmental toxicity and extremely low exposure, there is reasonable certainty that no harm to infants, children, or adults will result from aggregate exposure to 1-MCP residues. Exemption of 1-MCP from the requirements of a tolerance should pose no significant risk to humans or the environment

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 Endocrine Disruptor Screening Program have been developed, 1-MCP 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 1-MCP. In addition, 1-MCP does not share any structural similarity to any known endocrine disruptive chemical.

B. Analytical Method(s)

EPA is establishing an exemption from the requirement of a tolerance without any numerical limitation for the reasons stated above, including 1-MCP's lack of mammalian toxicity. For the same reasons, the Agency has concluded that an analytical method is not required for enforcement purposes for 1-MCP.

C. Codex Maximum Residue Level

No Codex maximum residue levels are established for residues of 1-MCP in or on any food or feed crop. There are no established tolerances or exemptions from tolerance for 1-MCP in the United States. The Agency has classified 1-MCP as a biochemical pesticide.

VIII. Conclusions

Based on the toxicology data submitted, there is reasonable certainty no harm will result from aggregate exposure of residues of 1-MCP to the U.S. population, including infants and children, when the proposed product is used in accordance with label instructions and good agricultural practices. This includes all anticipated dietary exposures and all other exposures for which reliable data were submitted, accepted and reviewed. The Agency has arrived at this conclusion based on the data submitted demonstrating no toxicity at the maximum doses tested. As a result, EPA establishes an exemption from tolerance requirements pursuant to FFDCA 408(c) and (d) for residues of 1-MCP in or on all food commodities.

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 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).

X. Regulatory Assessment Requirements

This final rule establishes an exemption from the tolerance requirement 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, 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 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 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 FFDCA section 408(n)(4). 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 Start Printed Page 48800Indian 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.

XI. 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).
