40 CFR Part 180

[OPP-301017; FRL-6595-9]
RIN 2070-AB


Humic Acid, Sodium Salt, Exemption Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of humic acid, sodium salt when used as an
inert ingredient (adjuvant, UV protectant) in pesticide formulations
applied to growing crops and raw agricultural commodities after
harvest. LignoTech USA, Inc. 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 humic acid, sodium salt.

DATES: This regulation is effective July 18, 2000. Objections and
requests for hearings, identified by docket control number OPP-301017,
must be received by EPA on or before September 18, 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-301017 in the
subject line on the first page of your response.

II. Background and Statutory Findings

    In the Federal Register of April 12, 2000 (65 FR 19759) (FRL-6498-
8), 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 petition PP 6E4705 by, LignoTech USA, Inc., 100
Highway 51 South, Rothschild, WI 54474-1198. This notice included a
summary of the petition prepared by the petitioner LignoTech USA, Inc.
There were no comments received in response to the notice of filing.
    The initial petition requested that 40 CFR 180.1001(c) and (e) be
amended by establishing an exemption from the requirement of a
tolerance for residues of humic acid, sodium salt. Subsequently the
petitioner revised the petition to request the establishment of an
exemption from the requirement of a tolerance for residues of humic
acid, sodium salt under 40 CFR 180.1001(c) only.
    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 44470]]

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 humic
acid, sodium salt are discussed in this unit.
    Humic substances including humic acid, sodium salt occur naturally
in the environment, as they are derived from soil or soil deposits.
Humic acid, sodium salt is a hydrophilic, reversible colloid whose
molecular weight ranges from 2,000-500,000 daltons. Chemically, humic
acids are complex, polymeric polyhydroxy acids formed by the process of
degradation of organic matter under the action of soil microorganisms
and ground worms.
    The Agency has reviewed three mammalian acute toxicity tests. In an
acute oral toxicity test of humic acid, sodium salt, an LD50
> 5,000 milligrams/kilograms (mg/kg) was determined. This was Toxicity
Category IV. In a primary dermal irritation test, humic acid, sodium
salt was found to be Toxicity Category IV. In a primary eye irritation
test, humic acid, sodium salt was found to be a mild eye irritant. This
was Toxicity Category III. Due to placement in Categories III and IV,
no acute effects are expected to occur. Due to the ubiquitous nature of
humic substances including humic acid, sodium salt, no chronic effects
are expected to occur. There is no available information to indicate
that these naturally occuring substances are carcinogenic, mutagenic,
or are expected to have any effect on the immune or endocrine systems.

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. Food. Not only are humic substances abundant in nature, but they
have been used in commercial agriculture for years to condition soils.
Therefore, increased dietary exposure from the use of humic acid,
sodium salt as an inert ingredient in pesticide formulations is
expected to be minimal.
    2. Drinking water exposure. Humic substances occur in abundance in
nature, including soils, fresh water and oceans. Increased drinking
water exposure from the use of humic acid, sodium salt in pesticide
formulations would not be expected.

B. Other Non-Occupational Exposure

    Humic substances occur in abundance in nature, including soils that
are in and around the home. The potential for an increase in the
existing non-dietary exposure to the general population, including
infants and children, is unlikely as these pesticide formulations
containing humic acid, sodium salt would be used in agricultural and
horticultural settings.

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 humic acid, sodium salt
shares a common mechanism of toxicity with other chemicals. However,
humic acid, sodium salt is expected to be practically non-toxic to
mammals. Due to the expected lack of toxicity, a cummulative risk
assessment is not necessary.

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

    Humic substances are present in abundance in the soil and the
environment. Humic substances have been used in commercial agriculture
for years to condition soils. Based on known acute toxicity studies,
humic acid, sodium salt is not acutely toxic. Due to the ubiquitous
nature of humic substances including humic acid, sodium salt, no
chronic effects are expected to occur. There is no available
information to indicate that these naturally occuring substances are
carcinogenic or mutagenic, or expected to have any effect on the immune
or endocrine systems. Because of its abundance in nature and lack of
toxicity, the Agency did not use the safety factor analysis in
evaluating the risk posed by humic acid, sodium salt and did not apply
an additional tenfold safety factor to protect infants and children.
    Based on the information in this preamble, EPA concludes that there
is a reasonable certainty of no harm from aggregate exposure to
residues of humic acid, sodium salt. Accordingly, EPA finds that
exempting humic acid, sodium salt from the requirement of a tolerance
will be safe.

VII. Other Considerations

A. Analytical Method

    An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.

B. Existing Tolerances Exemptions

    There are no existing tolerance exemptions for humic acid, sodium
salt.

C. International Tolerances

    There are no international tolerances or tolerance exemptions for
humic acid, sodium salt. No CODEX maximum residue levels have been
established for humic acid, sodium salt.

D. Conclusion

    Therefore, based on the information and the data considered, EPA is
establishing an exemption from the requirement of a tolerance for
residues of humic acid, sodium salt.

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

    3. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit VIII.A.,
you should also send a copy of your request to the PIRIB for its
inclusion in the official record that is described in Unit I.B.2. Mail
your copies, identified by docket control number OPP-301017, to: Public
Information and Records Integrity Branch, Information Resources and
Services Division (7502C), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460.
In person or by courier, bring a copy to the location of the PIRIB
described in Unit I.B.2. You may also send an electronic copy of your
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 (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).

[[Page 44472]]

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).
