II. Background and Statutory Findings

In the Federal Register of January 28, 2004 (69 FR 4151) (FRL7339 2), EPA issued a notice pursuant to section 408(d)(3) of the FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance petition (PP 3F6765) by EDEN Bioscience Corporation, 3830 Monte Villa Parkway, Bothell, WA 980216942. This notice included a summary of the petition prepared by the petitioner EDEN Bioscience Corporation. There were no comments received in response to the notice of filing.

The petition requested that 40 CFR part 180 be amended by establishing a temporary exemption from the requirement of a tolerance for residues of harpin protein.

Section 408(c)(2)(A)(i) of 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 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. Pursuant to section 408(c)(2)(B) of FFDCA, in establishing or maintaining in effect an exemption from the requirement of a tolerance, EPA must take into account the factors set forth in section 408(b)(2)(C) of FFDCA, which require 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 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 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.

This final rule amends the previously established exemption from the requirement of a tolerance for harpin protein published in the Federal Register of May 3, 2000 (65 FR 25660) (FRL64974). Research on other harpin proteins that are similar to this active ingredient indicates that many of these proteins also exhibit activities of commercial value in crop production. Because the existing tolerance exemption codified in 40 CFR 180.1204 does not specify the scope of harpin proteins that are exempt, this final rule clarifies the existing exemption by specifying the criteria a protein must meet in order to be subject to the exemption. Harpin proteins exhibit no adverse effects in Tier I mammalian toxicity studies; therefore, Tier II and III study requirements are waived. Acute oral and dermal toxicity LD 50 values for products containing harpin protein are greater than 5,000 grams/kilograms (g/kg) in the rat (Toxicity Category IV, least toxic). Inhalation studies in the rat on products containing harpin protein resulted in an LC50 of greater than 2 milligrams/liter (mg/L) (Toxicity Category IV). In addition, no adverse effects are observed in eye irritation studies in the rabbit at 100 mg (Toxicity Category IV). There have been no reported incidents of hypersensitivity in individuals exposed to products containing harpin protein during research, production, and/or field testing, and there are no published reports indicating that harpin proteins are toxic. Further, harpin proteins have a nontoxic mode of action and work by activating the treated plant's own growth and defense systems. In order to be exempt from the requirement of a tolerance, a harpin protein must meet the following specification:

1. Consists of protein less than 100 kD in size, that is acidic (pI<7.0), glycine rich (>10%), and contains no more than one cystine residue.

2. The source(s) of genetic material encoding the protein are bacterial plant pathogens not known to be mammalian pathogens.

3. Elicits the hypersensitive response (HR) which is characterized as rapid, localized cell death in plant tissue after infiltration of harpin into the intercellular spaces of plant leaves.

4. Possesses a common secondary structure consisting of [alpha] and [beta] units that form an HR domain.

5. Is heat stable (retains HR activity when heated to 65[deg]C for 20 minutes).

6. Is readily degraded by a proteinase representative of environmental conditions (no protein fragments >3.5 kD after 15 minutes degradation with Subtilisin A).

7. Exhibits a rat acute oral toxicity (LD50) of greater than 5,000 mg product/kg body weight.

IV. Aggregate Exposures

In examining aggregate exposure, section 408 of FFDCA directs EPA to consider available information concerning exposures from the pesticide residue in food and all other nonoccupational 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

Harpin proteins are common constituents of plant pathogenic bacteria which are often found on fruits and vegetables. Additional dietary exposure to harpin protein resulting from labeled uses is unlikely to occur because of extremely lowuse rates and rapid degradation in the field. Furthermore, the lack of demonstrable toxicity in acute studies, and the natural occurrence of harpins in the environment support the establishment of an exemption from the requirement of a tolerance for harpin protein.

1. Food. Products containing harpin protein are applied at very low rates of application (grams of active ingredient per acre). Harpin proteins are also rapidly degraded in the environment by common proteinases, ultraviolet (UV) irradiation, and oxidizing agents. No residues of active ingredient are detectable, using available methods, on treated crops even immediately after application. Therefore, the Agency believes that dietary exposure to harpin protein via consumption of treated food or feed will be negligible.

2. Drinking water exposure. Because harpin protein is applied at extremely lowuse rates and rapidly degrades in the environment, residues are unlikely to occur in ground or surface water. In addition, harpin protein is highly sensitive to small amounts of chlorine or similar oxidizing agents as contained
[[Page 24994]]
in many municipal water systems. Therefore, residues of harpin protein are unlikely to occur in drinking water.

B. Other NonOccupational Exposure

The Agency believes that the potential for nondietary exposure and attendant risks to the general population, including infants and children, is minimal to nonexistent, due to lowuse rates, the instability of harpin protein in the environment, and lack of demonstrated toxicity. In addition, with the exception of turf and ornamentals, the proposed use sites are primarily commercial agricultural and horticultural, as opposed to domestic settings. Increased nondietary exposures to harpin protein via home and garden uses is not considered likely because of the typically lowuse rates and lack of persistence in the environment.

1. Dermal exposure. Products containing harpin protein are classified as Toxicity Category IV (least toxic) for dermal exposure, and are not expected to pose any risk via the dermal route.

2. Inhalation exposure. Acute inhalation tests place products containing harpin protein in Toxicity Category IV (least toxic), thus risk via the inhalation route is expected to be minimal to non existent.

V. Cumulative Effects

Section 408(b)(2)(D)(v) of FFDCA requires the Agency to consider the cumulative effects of exposure to harpin protein and to other substances that have a common mode of toxicity. These considerations include the possible cumulative effects of such residues on infants and children. Because of the lack of demonstrable toxicity of harpin protein in acute toxicity studies, lack of information indicating that any toxic effects, if they existed, would be cumulative with any other compounds, extremely lowuse rates, and rapid degradation in the environment, the Agency does not expect any cumulative or incremental effects from exposure to residues of this product when used as directed on the label.
VI. Determination of Safety for U.S. Population, Infants and Children

Harpin protein's lack of toxicity has been demonstrated by the results of acute toxicity testing in mammals in which harpin protein caused no adverse effects when dosed orally, dermally, and via inhalation at the limit dose for each study. Therefore, EPA concludes that there is a reasonable certainty that no harm to the U.S. population in general, and to infants and children, specifically, will result from aggregate exposure to residues of harpin protein. This includes all anticipated dietary exposures and all other exposures for which there is reliable information. Accordingly, exempting harpin proteins that meet the criteria specified in this preamble is considered safe and poses no risk. Section 408(b)(2)(C) of FFDCA 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 database, unless EPA determines that a different margin of exposure will be safe for infants and children. Margins of exposure (safety) are often referred to as uncertainty factors. Here, based on all the available information and for all the reasons already set forth in this final rule, the Agency finds that there are no threshold effects of concern to infants, children, and adults when harpin protein is used as labeled, and that the provision requiring an additional margin of safety is not necessary to protect infants and children. As a result, EPA has not used a margin of exposure (safety) approach to assess the safety of harpin protein.
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 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 has 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, harpin protein may be subjected to additional screening and/or testing to better characterize effects related to endocrine disruption. Based on available data, no endocrine systemrelated effects have been identified with consumption of harpin protein. To date, there is no evidence to suggest that harpin protein affects the immune system, functions in a manner similar to any known hormone, or that it acts as an endocrine disruptor.

B. Analytical Method(s)

The Agency is establishing an exemption from the requirement of a tolerance without any numerical limitation for the reasons enumerated in this preamble, including harpin protein's demonstrated lack of toxicity, and instability in the environment. Accordingly, the Agency has concluded that an analytical method is not needed for enforcement purposes for harpin protein residues.

C. Codex Maximum Residue Level

There is currently no CODEX Maximum Residue Limit set for food use of this active ingredient.

VIII. 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.

IX. Statutory and Executive Order Reviews

This final rule establishes an exemption from the tolerance requirement 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, 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 1044). Nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and LowIncome 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 104113, 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 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
[[Page 24996]]
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.

X. 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). List of Subjects in 40 CFR Part 180
