Yucca Extract; 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 the yucca extract on raw agricultural
commodities when applied/used in accordance with good agricultural
practices as an inert ingredient in pesticide formulations applied to
growing crops. EDM Corporation 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 yucca extract.

DATES:  This regulation is effective September 29, 2000. Objections and
requests for hearings, identified by docket control number OPP-301067,
must be received by EPA on or before November 28, 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-301067 in the
subject line on the first page of your response.

II. Background and Statutory Findings

    In the Federal Register of November 20, 1998 (63 FR 64494) (FRL-
6027-7), 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, EDM Corporation, 2278 S.
Indiana St., Porterville, CA 93257. This notice included a summary of
the petition prepared by the petitioner EDM Corporation. 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 yucca extract.
     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 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

[[Page 58435]]

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 are
discussed in this unit.
     An acute oral gavage toxicity study performed on Sprague-Dawley
derived rats was performed on a 70% yucca extract syrup. The
LD50 for males was found to be greater than 5,000 milligram/
kilogram (mg/kg), and for females it was calculated to be greater than
500 mg/kg. Even though the use of a 70% extract is a minor deviation
from accepted guidelines, the Agency concluded that yucca extract
belonged in Toxicity Category III. Thus, there are no concerns for
acute oral exposure.
    Yucca extract has been historically used among the Native American
population in Mexico and the United States for medicinal purposes. It
was approved by the U.S. Food and Drug Administration (FDA) as a
natural food additive under 21 CFR 172.510. Furthermore, it has been
used as a dietary supplement without evidence of toxicity. For these
reasons, the Agency has concluded there are no concerns for chronic
oral exposure, and that chronic toxicity data were not necessary.

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

    Yucca extract is derived from the species Yucca schidigera which is
part of the lily family of plants and is native to the deserts of
Southwestern United States and Northern Baja California, Mexico. The
plant and its extracts have a long history of safe use as food material
for both humans and livestock. It is used for human consumption in the
soft drink industry, natural food supplement, cosmetics, etc. Other
uses include: natural feed additive for livestock, poultry, swine,
pets, and shrimp to reduce ammonia, hydrogen sulfide and offensive
odors. The extract is approved by the FDA as a natural food additive
under 21 CFR 172.510.
    1. Food. Information supplied to the Agency indicates that
approximately 350 tons of raw yucca material are used annually in the
United States. It is expected that 150 tons of these materials would be
used in making yucca extract for agricultural uses. A 70% yucca extract
solution would be used in pesticide products in a concentration no
greater than 6%. If yucca extract is approved as an inert ingredient in
pesticide products to be applied to food crops, it can be assumed that
exposure to yucca extract will increase. However, the amount of
increase is necessarily limited by the availability of raw yucca. In
addition, the main ingredient in yucca extract is sarsaponin which is
naturally found in several types of food, such as legumes and asparagus
at significant levels. The Agency concludes that the use of yucca
extract as an inert ingredient would result in a negligible increase in
exposure over those levels which would occur as the result of the use
of yucca extract as an unrestricted food additive or naturally as the
result of ingestion of various food items.
    2. Drinking water exposure. Yucca extract has general history of
safe use as a natural food additive approved by the FDA under 21 CFR
172.510 present in dietary supplements, herbal teas, soft drinks, among
others. The main ingredient in yucca extract, sarsaponin, has been
shown to degrade in 60 deg.C water within 8 days. Because of this rapid
degradation, the lack of toxicity and its history of safe use, the
Agency is confident that the use of yucca extract as a food-use inert
ingredient in pesticide products will not affect the water supply.

B. Other Non-Occupational Exposure

    On October 6, 1998, the Agency approved the use of yucca extract as
a non-food use inert ingredient in pesticide formulations applied to
grasses grown for seeds and for sod. No data was required for this
approval. The Agency has determined that due to the long history of
safe use as a dietary supplement and food additive, there is no need
for the petitioners to submit dermal and inhalation exposure data.

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 yucca extract shares a common
mechanism of toxicity with other chemicals. However, yucca extract 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

    Yucca extract has been approved for use in food and beverages by
the FDA under 21 CFR 172.510 with no limits. As previously stated in
sections A1 and A2, approval of yucca extract as an inert ingredient
for use on food crops will not significantly increase dietary exposure
to this chemical. Accordingly, there is reasonable certainty that no
harm will result from aggregate exposure of the U.S. population,
including infants and children, to yucca extract.
    The Agency did not use the safety factor analysis in evaluating the
risk posed by the compound. The lack of toxicity of yucca extract
supported not applying an additional tenfold safety factor to protect
infants and children. In conclusion, the Agency is reasonably certain
that no harm will result to infants and children, or to the general
population from aggregate exposure to residues of yucca extract.
Accordingly, EPA finds that exempting yucca extract 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 yucca extract for
endocrine effects may be required. At this moment, there is no evidence
that yucca extract is an endocrine disruptor.

B. Analytical Method(s)

    Since an exemption from the requirement of a tolerance is being
established without restriction on residue level, the Agency has
concluded that an analytical method is not required for enforcement
purposes for yucca extract from Yucca schidigera.

[[Page 58436]]

C. Existing Tolerance Exemptions

    There are no existing tolerance exemptions for yucca extract from
Yucca schidigera.

D. International Tolerances

    There are no international tolerances or tolerance exemptions for
yucca extract from Yucca schidigera.

E. Conclusion

    Therefore, based on the information and the data considered, EPA is
establishing an exemption from the requirement of a tolerance for
residues of yucca extract from Yucca schidigera.

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.

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

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 file 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 October 4, 1993 (58 FR
51735). 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 May 19,
1998 (63 FR 27655); special considerations as required by Executive
Order 12898, entitled Federal Actions to Address Environmental Justice
in Minority Populations and Low-Income Populations February 16, 1994
(59 FR 7629); or require OMB review or any Agency action under
Executive Order

[[Page 58437]]

13045, entitled Protection of Children from Environmental Health Risks
and Safety Risks April 23, 1997 (62 FR 19885). 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
August 10, 1999 (64 FR 43255). 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).
