Cucurbitacins; Exemption from the Requirement of a Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This regulation establishes an exemption from the requirement 
of a tolerance for residues of cucurbitacins from the powders and 
juices of the Hawkesbury melon Citrullus lanatus on various food 
commodities when applied/used as an inert (other) ingredient (gustatory 
stimulant) in pesticides applied to growing crops only. Agricultural 
Research Services, United States Department of Agriculture 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 cucurbitacins from Hawkesbury melon.

DATES: This regulation is effective March 22, 2000. Objections and 
requests for hearings, identified by docket control number OPP-300965, 
must be received by EPA on or before May 22, 2000.

ADDRESSES: Written objections and hearing requests may be submitted by 
mail, in person, or by courier. Please follow the detailed instructions 
for each method as provided in Unit VIII. of the ``SUPPLEMENTARY 
INFORMATION.'' To ensure proper receipt by EPA, your objections and 
hearing requests must identify docket control number OPP-300965 in the 
subject line on the first page of your response.

II. Background and Statutory Findings

    In the Federal Register of September 1, 1999 (64 FR 47788) (FRL-
6098-6), EPA issued a notice pursuant to section 408 of the Federal 
Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, as amended by the 
Food Quality Protection Act (FQPA) (Public Law 104-170) announcing the 
filing of a pesticide tolerance petition by, Agricultural Research 
Services, United States Department of Agriculture, Agricultural 
Research Center, Beltsville, MD 20705. This notice included a summary 
of the petition prepared by the petitioner United States Department of 
Agriculture. There were no comments received in response to the notice 
of filing.
    The petition requested that 40 CFR 180.1001(d) be amended by 
establishing an exemption from the requirement of a tolerance for 
residues of cucurbitacins derived from the Hawkesbury melon Citrullus 
lanatus. The petitioner noted that the Agency had previously 
established exemptions from the requirement of a tolerance for the use 
of buffalo gourd and zucchini juice, as sources of the inert ingredient 
cucurbitacin (57 FR 40128, September 2, 1992 and 63 FR 43085, August 
12, 1998), and is seeking to add the Hawkesbury melon Citrullus lanatus 
as an additional source of cucurbitacins.
    Section 408(b)(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(b)(2)(A)(ii) defines ``safe'' to 
mean that ``there is a reasonable certainty that no harm will result 
from aggregate exposure to the pesticide

[[Page 15249]]

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.* * *''
    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. The nature of the toxic effects caused by 
cucurbitacins are discussed in this unit.
    The Agency in a previous Federal Register notice reviewed mammalian 
toxicity data submitted on zucchini juice and buffalo gourd root powder 
as part of the establishment of an exemption from the requirement of a 
tolerance for residues of zucchini juice when used as an alternative 
source of the inert ingredient gustatory stimulant cucurbitacin (63 FR 
43085). A summary of the comparative toxicology data showed a more 
favorable toxicological profile for the zucchini juice, as compared to 
the buffalo gourd root powder, as a cucurbit source of cucurbitacins. 
Zucchini juice was shown to be practically non-toxic to mammals. The 
acute oral, acute dermal, acute inhalation, primary eye, and skin 
irritation were all toxicity category IV. No acute systemic toxicity, 
irritation or dermal sensitization was exhibited in the studies 
performed with the zucchini juice.
    Due to the low levels of cucurbitacins used in the field no acute 
effects are expected to occur. In addition, due to their rapid 
degradation, no chronic effects are expected to occur. Neither 
cucurbitacins nor their metabolites are known or expected to have any 
effect on the immune or the endocrine systems. These chemicals are not 
known to be carcinogenic.
    According to information supplied by USDA, the Hawkesbury 
watermelon contains cucurbitacin E-glycoside at levels in the same 
order of magnitude those found in buffalo gourd root powder, 0.76 
milligrams (mg) cucurbitacin E-glycoside/grams (gm) of melon compared 
to 0.59 mg cucurbitacin E-glycoside/gm of root powder. The Hawkesbury 
melon does not contain cucurbitacin I. Cucurbitacin I is considered to 
be more toxic than cucurbitacin E-glycoside (LD50 of 40 
milligrams/kilograms (mg/kg) to 5 mg/kg). Thus, Hawkesbury melon is 
also likely to exhibit lower toxicity than buffalo gourd root powder, 
providing an additional margin of safety.

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 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

    Species of the family Cucurbitaceae, such as melons, pumpkins and 
squash, are commonly used as fruits and vegetables throughout the 
world, they are naturally occurring and widely available. Seeds of 
several species are used as sources of flavorings in bakery goods or 
for oils and proteins. All of these species contain some assortment of 
naturally occurring cucurbitacins in varying concentrations.
    1. Food. In the Federal Register notice published on August 12, 
1998 (63 FR 43085), the Agency reviewed available data on the dietary 
exposure to cucurbitacins. The use to control corn rootworm is given as 
an example. Assuming that the maximum permitted level of 3.4 gm/acre/
season is applied, with no loss either in the field or during 
processing, and that all the material is concentrated in the grain, the 
following exposure would result. The average yield of corn in the 
United States is 120-130 bushels per acre. At 56 pounds of corn per 
bushel, the minimum yield is 6,720 pounds per acre and the level of 
cucurbitacin would be 0.000506 grams of cucurbitacin per pound of corn. 
A gram of ``straightneck'' squash contains 0.00139 grams of 
cucurbitacin. Thus, even under these worst case assumptions, 
consumption of a pound of treated corn would add less cucurbitacin to 
the diet than a gram serving of squash. At the allowable rate of 
application the proposed use of these compounds as inert ingredients 
would result in a negligible increase in exposure to cucurbitacins over 
those levels which would occur naturally as the result of ingestion of 
various cucurbit commodities.
    2. Drinking water exposure. The Agency review cited in the August 
12, 1998, Federal Register notice established that most cucurbitacins 
are insoluble in water and transfer of these cucurbitacins to ground 
water is unlikely. The more water soluble glycosylated forms of 
cucurbitacins are less toxic to humans. No uses are registered for 
application to bodies of water.

B. Other Non-Occupational Exposure

    There are no cucurbitacin-containing products with residential uses 
as all uses are for agricultural crop production only.

V. Cumulative Effects

    Section 408 (b)(2)(D)(v) of FFDCA requires that, when considering 
whether to establish, modify or revoke a tolerance or tolerance 
exemption, the Agency consider ``available information'' concerning the 
cumulative effects of a particular chemical's residues and ``other 
substances that have a common mechanism of toxicity.'' The Agency has 
not made any conclusions as to whether or not cucurbitacins share a 
common mechanism of toxicity with other chemicals. However, the 
Hawkesbury melon juice is expected to be practically non toxic to 
mammals. Due to the expected lack of toxicity, a cumulative risk 
assessment is not necessary.

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

    Cucurbitacins are present in varying amounts in many plants 
regularly consumed by the general public, such as squash, gourds and 
watermelon. Information available to the Agency indicates that the 
maximum projected additional exposure to these compounds is 
significantly less than that from a normal serving of these plants, as 
previously discussed in section IV(A)(1). The residual amount of 
cucurbitacins in a pound of corn, for example, is an order of magnitude 
less than the naturally occurring levels of these substances in a 
single serving of squash. Dietary exposure to

[[Page 15250]]

cucurbitacins through food is not likely to significantly increase due 
to their use as inert ingredients applied to agricultural commodities. 
These chemicals are not likely to be found in water. In addition, the 
use sites of the cucurbitacins are all agricultural for the control of 
Diabriticine beetles (corn rootworm and cucumber beetles). Therefore, 
non-dietary exposure to infants and children is not expected.
    The Agency had previously established in the Federal Register 
notice published on August 12, 1998 (63 FR 43085) that cucurbitacins 
contained in zucchini juice were practically non toxic to mammals. 
Cucurbitacins in Hawkesbury melon are expected to be of similar 
toxicity. Because of this, the Agency did not use the safety factor 
analysis in evaluating the risk posed by the compound. This lack of 
toxicity also supported not applying an additional tenfold safety 
factor to protect infants and children. In conclusion, the Agency is 
reasonaly certain that no harm will result to infants and children, or 
to the general population from a minimally increased exposure to 
residues of cucurbitacins. Based on the information in this preamble, 
EPA concludes that there is a reasonable certainty of no harm from 
aggregate exposure to residues. Accordingly, EPA finds that exempting 
cucurbitacin residues from the requirement of a tolerance will be safe.

VII. Other Considerations

A. Endocrine Disruptors

    FQPA requires EPA to develop a screening program to determine 
whether certain substances, including pesticides and inert ingredients, 
``may have an effect in humans that is similar to an effect produced by 
a naturally occurring estrogen, or such other endocrine effect....'' 
The Agency has been working with interested stakeholders to develop a 
screening and testing program as well as a priority setting scheme. As 
the Agency proceeds with implementation of this program, further 
testing of products containing the inert ingredient cucurbitacin for 
endocrine effects may be required. At this moment, there is no evidence 
that cucurbitacins are endocrine disruptors.

B. Analytical Method(s)

    The Agency is establishing an exemption from the requirement of a 
tolerance without any change in the previously established limits of no 
more than 2.5 pounds/acre/season (3.4 grams cucurbitacin/acre/season). 
Therefore, the Agency has concluded that an analytical method is not 
required for enforcement purposes of cucurbitacins from the Hawkesbury 
melon.

C. Existing Tolerances

    Prior EPA findings include a temporary exemption for the 
requirements of a tolerance for residues of the buffalo gourd, 
Cucurbita foetidissima, root powder as a source of cucurbitacins in or 
on the raw agricultural commodity fields corn for the control of adult 
corn rootworms (55 FR 49700, November 30, 1990). In addition, the 
Agency established a permanent exemption from the requirement of a 
tolerance for the residues of buffalo gourd root powder when used as an 
inert ingredient (gustatory stimulant) in pesticide formulations 
applied to growing crops only (57 FR 40128, September 2, 1992). In 
1998, the Agency amended the permanent exemption from the requirement 
of a tolerance to add the residues of zucchini juice, Cucurbita pepo, 
to the list of inert ingredients (63 FR 43085, August 12, 1998).

D. International Tolerances

    There are no international tolerances or tolerance exemptions for 
cucurbitacins.

E. Conclusion

    Therefore, based on the information and the data considered, as 
well as previous tolerance exemptions granted to cucurbitacins from 
buffalo gourd root powder and zucchini juice, EPA is establishing an 
exemption from the requirement of a tolerance for residues of 
cucurbitacins from the Hawkesbury melon.

VIII. 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.

format 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 issues(s) in the manner sought 
by the requestor would be adequate to justify the action requested (40 
CFR 178.32).

IX. 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). 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 
prior consultation as specified by Executive Order 13084, entitled 
Consultation and Coordination with Indian Tribal Governments (63 FR 
27655, May 19,1998); special considerations as required by Executive 
Order 12898, entitled Federal Actions to Address Environmental Justice 
in Minority Populations and Low Income Populations (59 FR 7629, 
February 16, 1994); or require 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 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).

X. 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).
