Summaries of Petitions

    The petitioner summaries of the pesticide petitions are printed 
below as required by section 408(d)(3) of the FFDCA. The summaries of 
the petitions were prepared by the petitioners and represent the view 
of the petitioners. EPA is publishing the petition summaries verbatim 
without editing them in any way. The petition summaries announce the 
availability of a description of the analytical methods available to 
EPA for the detection and measurement of the pesticide chemical 
residues or an explanation of why no such method is needed.

1. LignoTech USA, Inc.

6E4705

    EPA has received a pesticide petition (6E4705) from LignoTech USA, 
Inc., 100 Highway 51 South, Rothschild, WI 54474-1198 proposing, 
pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act 
(FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180 to establish an 
exemption from the requirement of a tolerance for residues of humic 
acid, sodium salt when used as an inert ingredient in pesticide 
formulations applied to growing crops, raw agricultural commodities 
(RAC) after harvest, or to animals. EPA has determined that the 
petition contains data or information regarding the elements set forth 
in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated 
the sufficiency of the submitted data at this time or whether the data 
support granting of the petition. Additional data may be needed before 
EPA rules on the petition. Pursuant to section 408(d)(2)(A)(i) of the 
FFDCA, as amended, LignoTech USA, Inc. has submitted the following 
information, data and arguments in support of their petition.

A. Product Identity

    1. Product chemistry. Humic substances are ubiquitous in the 
environment, including soils, fresh water and oceans. Humic acid, 
sodium salt (synonym: sodium humate) has been defined as the portion of 
soil organic matter that is soluble in base and insoluble in mineral 
acid or alcohol. A variety of brown materials, not occurring in soil, 
have also, been designated humic acids. Two examples of the latter are 
the dark-colored substances from coal and from marine sediment.
    Humic acid (CAS No. 68131-04-4) is a hydrophilic, reversible 
colloid whose molecular weight ranges from 2,000 daltons for the more 
soluble form to 500,000 daltons for the less soluble form. The average 
molecular weight for humic acids is in the 20,000-50,000 daltons range. 
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.
    Most humic acids of commercial use are produced by extraction of 
naturally occurring lignite and brown coals with alkali. The sodium 
salt of humic acid is produced by extraction of Leonardite with sodium 
hydroxide.
    2. Proposed use practice. Humic acid, sodium salt is proposed for 
use as an inert ingredient in pesticide formulations that would 
typically be applied to growing crops. Humic acid, sodium salt has been 
used safely in commercial agriculture for many years, and is generally 
applied via tank mixing with fertilizers, and/or pesticides, or as 
granules. Humates such as humic acid, sodium salt are beneficial to 
growing plants, and are reported to affect germination speed, nutrient 
uptake, promote root and plant growth, and increase pesticide 
effectiveness. Use levels of humic acid, sodium salt are anticipated to 
be in the range of 5 to 50% by weight of the product formulation, with 
the typical use level expected to be in the 5 to 10% use range. It is 
anticipated that humic acid, sodium salt would be added directly to the 
pesticide active ingredient at the time of manufacture/formulation, or 
it would be tank-mixed with the pesticide at the time of application.
    3. Magnitude of residues. It is not expected that, when used as 
proposed, humic acid, sodium salt would result in residues that would 
remain in human food items.

B. Toxicological Profile

    1. Acute toxicity. Humic acid, sodium salt is ubiquitous in the 
environment, and is derived from soil or soil deposits. Sodium humates 
and humic acids are generally recognized as having low mammalian, 
aquatic and avian toxicity. Toxicity testing of LignoTech USA, Inc.'s 
humic acid, sodium salt product (trade name: Lignosol UVB; code number: 
D-1109) indicated an acute oral toxicity of LD50 > 5,000 
milligrams/kilograms (mg/kg) Toxicity Category IV, no primary skin 
irritation Toxicity Category IV, and mild eye irritation Toxicity 
Category III. The results of these acute toxicity studies indicate 
Toxicity Category III or IV, which pose

[[Page 19761]]

no significant human health risks. Published literature reports that 
humic acid is nongenotoxic, nonteratogenic and nonmutagenic to test 
animals. There are no reports in the literature of humic acid, sodium 
salt causing disease or injury to man or other animals. No incidents of 
hypersensitivity have been reported in the published literature by 
researchers, manufacturers or users.
    2. Genotoxicty. A study published on the in vivo cytogenic effects 
of natural humic acid determined that ``humic acid has not been 
demonstrated to be genotoxic either in vitro or in vivo.''
    3. Endocrine disruption. To date there is no evidence to suggest 
that humic acid, sodium salt functions in a manner similar to any known 
hormone, or that it acts as an endocrine disrupter.

C. Aggregate Exposure

    1. Dietary exposure. Dietary exposure from use of humic acid, 
sodium salt in pesticide formulations is minimal. Even if exposure 
occurred, the lack of reports of disease in man or animals indicates 
there is no risk for these exposures.
    i. Food. Dietary exposure from use of humic acid, sodium salt in 
pesticide formulations is minimal. Residues of humic acid, sodium salt 
are not expected on agricultural commodities. Humic substances are 
ubiquitous in nature and have been used for many years in commercial 
agriculture without adverse effect.
    ii. Drinking water. Humic substances are ubiquitous in nature, 
including soils, fresh water and oceans. Increased drinking water 
exposure from use of humic acid, sodium salt in pesticide formulations 
would not be expected. Humic acid, sodium salt has been widely used in 
commercial agriculture for many years without adverse effect.
    2. Non-dietary exposure. The potential for non-dietary exposure to 
the general population, including infants and children, is unlikely as 
the proposed use sites of pesticide formulations that would contain 
humic acid, sodium salt are commercial, agricultural and horticultural 
settings. However, non-dietary exposures would not be expected to pose 
any quantifiable risk due to a lack of residues of toxicological 
concern. In addition, the personal protective equipment required for 
use of most pesticide formulations mitigates the potential for exposure 
to applicators and handlers of the proposed products, when used in 
commercial, agricultural and horticultural settings.

D. Cumulative Effects

    It is not expected that, when used as proposed, humic acid, sodium 
salt would result in residues that would remain in human food items. 
Data on humic acid, sodium salt has shown a lack of toxicity to humans 
or other animal species, as well as no information in the literature 
indicating a cumulative effect with any other compound. A cumulative 
risk assessment is therefore, not necessary.

E. Safety Determination

    1. U.S. population. Humic substances are ubiquitous in the 
environment. Based on known acute toxicity studies, humic acid, sodium 
salt is not toxic to humans. There have been no reports of toxins or 
secondary metabolites associated with humic acid, sodium salt, and the 
acute toxicity studies conducted have shown that it is nontoxic and 
nonirritating to test animals. Published literature reports that humic 
acid is nongenotoxic, nonteratogenic and nonmutagenic to test animals. 
Residues of humic acid, sodium salt are not expected on agricultural 
commodities, and therefore, exposure to the general U.S. population, 
from the proposed uses, is not anticipated.
    2. Infants and children. Residues of humic acid, sodium salt, when 
used in pesticide formulations, are not expected on agricultural 
commodities. There is a reasonable certainty of no harm for infants and 
children from exposure to humic acid, sodium salt from the proposed 
use.

F. 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.

2. PURAC America Inc.

5E4510

    EPA has received a pesticide petition (15E4510) from PURAC America 
Inc., Barclay Boulevard, Lincolnshire Corporate Center, Lincolnshire, 
IL 60069 proposing, pursuant to section 408(d) of the FFDCA, 21 U.S.C. 
346a(d), to amend 40 CFR part 180 to establish an exemption from the 
requirement of a tolerance for ethyl lactate when used as an inert 
ingredient in pesticide formulations applied to growing crops, RAC's 
after harvest or animals . EPA has determined that the petition 
contains data or information regarding the elements set forth in 
section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated 
the sufficiency of the submitted data at this time or whether the data 
support granting of the petition. Additional data may be needed before 
EPA rules on the petition.

A. Toxicological Profile

    1. Acute toxicity. The oral LD50 of butyl lactate in 
rats is greater than 2,000 mg/kg (top dose tested-per OECD Guideline 
No. 401). No mortality or macroscopic effects were noted. The 
(inhalation) LC50 for butyl lactate is 5,140 mg/kg (top 
aerosol concentration generated). It is known that lactates hydrolyze 
to lactic acid and the corresponding alcohol. No mortality or 
macroscopic effects at autopsy were noted. All animals gained weight 
during the 14-day observation period. The only clinical signs noted 
were decreased breathing frequency and wet head or fur during exposure 
and shortly after.
    2. Genotoxicity. Ames testing of similar lactate (ethyl lactate) 
did not show any activity. Butyl lactate should give similar results in 
these tests.
    3. Reproductive and developmental toxicity. Developmental and 
mutagen testing has not been conducted on butyl lactate, but ethyl 
lactate a similar lactate, has been evaluated. Dermal developmental 
testing of ethyl lactate in rats day 6-15 of gestation did not produce 
any developmental effects or other signs of toxicity in the dams or 
fetus other than skin irritation in the dams at the top dose (3.619 
grams/kilograms (g/kg)).
    4. Subchronic toxicity. Subacute inhalation studies have been 
conducted on two similar lactates (ethyl, isobutyl), but not on butyl 
lactate. Degenerative changes in the nasal cavity were noted in both 
studies. For ethyl lactate the effects were noted at 600 mg/
m3 and higher, primarily in the olfactory epithelium. In the 
case of isobutyl lactate, effects were seen at 400 mg/m3 and 
above, but less severe than ethyl lactate at the same concentrations. 
The affected areas tended to be more respiratory than olfactory 
epithelium for isobutyl lactate. The no observed adverse effect level 
(NOAEL) in both studies is 200 mg/m3. Based on the 
similarity of effects and kinetic parameters it appears that lactic 
acid is most likely the cause of the lactate toxicity. Butyl lactate 
would be expected to give similar results in a subacute inhalation 
test.
    5. Animal metabolism. The in vitro hydrolysis of lactate esters 
(methyl, ethyl, butyl, pentyl, isoamyl, isopropyl, isobutyl, 2-
ethylhexyl) in rat olfactory epithelium homogenate has been evaluated. 
In general of the eight lactates evaluated, the rat nasal epithelium 
showed increased capacity to hydrolyze the lactates and increased 
affinity with increasing molecular

[[Page 19762]]

weight (increase in alcohol chain length). The in vitro hydrolysis 
kinetic parameters were similar for ethyl and isobutyl lactate (Kmax 1. 
11 0. 7 mM, Vmax 70 and 180 nmol/min/mg respectively).
    6. Metabolite toxicology. Butyl lactate is readily hydrolyzed to 
lactic acid and N butyl alcohol (both are exempt from requirements for 
tolerance 40 CFR 180.1001). Lactic acid is a normal metabolite in 
humans and is found in or added to foods (21 CFR 172.515). Lactic acid 
oral LD50 in rats is 3,730 mg/kg. It is not active in 
mutagenic tests. It will produce skin and eye irritation at high 
concentrations. The sodium salt of lactic acid is used in cosmetics as 
a skin moisturizer and parental solutions in the pharmaceutical 
industry. Butyl alcohol is found in certain foods and beverages and is 
used as an approved flavoring agent (21 CFR 172.515). It is used as a 
solvent in fingernail products. Butyl alcohol oral LD50 in 
rats ranges from 700-2,100 mg/kg. It is not active in mutagenic tests. 
It will produce skin and eye irritation at high concentrations. It is 
not a developmental hazard in animals. Its primary effect in man is 
intoxication and narcosis.

B. Aggregate Exposure

    Non-dietary exposure. Butyl lactate will be used in animal, pre- 
harvest and post-harvest applications as a solvent, diluent, 
coalescence agent, surfactant and emulsifier at levels up to 50. It 
will be applied, at a maximum of 2-3 times per crop. The low vapor 
pressure would tend to keep airborne exposure low.

3. PURAC America Inc.

5E4515

    EPA has received a pesticide petition (15E4515) from PURAC America 
Inc., 111 Barclay Boulevard, Lincolnshire Corporate Center, 
Lincolnshire, IL 60069 proposing, pursuant to section 408(d) of the 
FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part 180 to establish an 
exemption from the requirement of a tolerance for ethyl lactate when 
used as an inert ingredient in pesticide formulations applied to 
growing crops, RACs after harvest or animals. EPA has determined that 
the petition contains data or information regarding the elements set 
forth in section 408(d)(2) of the FFDCA; however, EPA has not fully 
evaluated the sufficiency of the submitted data at this time or whether 
the data supports granting of the petition. Additional data may be 
needed before EPA rules on the petition.

A. Toxicological Profile

    1. Acute toxicity. The oral LD50 of ethyl lactate in 
rats is greater than 2,000 mg/kg (top dose tested-per OECD Guideline 
No. 401). No mortality or macroscopic effects were noted. All animals 
gained weight after 3 days. The inhalation LC50 for ethyl 
lactate is 5,400 mg/m3 (top aerosol concentration 
generated). It is known that lactates hydrolyze to lactic acid and the 
corresponding alcohol. No mortality was noted. Macroscopic effects at 
autopsy revealed pale lungs with dark spots.
    2. Genotoxicity. A Salmonella/Mammalian-Microsome Plate Assay 
(Ames) of ethyl lactate in five tester strains with and without 
metabolic activation did not show mutagenic activity.
    3. Reproductive and developmental toxicity. Dermal developmental 
testing of ethyl lactate in groups of 25 pregnant rats was conducted at 
0, 0.517, 1.551, or 3.619 g/kg/day for day 6-15 of gestation. No 
developmental effects or other sign of toxicity in the dams or fetus 
other than skin irritation in the dams at the top dose was observed. 
The matemal NOAEL (based on skin irritation) is greater than 1.551 g/
kg/day. The developmental NOAEL was greater than 3.619 g/kg.
    4. Subchronic toxicity. Subacute inhalation studies have been 
conducted on ethyl lactate. Degenerative changes in the nasal cavity 
were noted in both studies. Groups of rats (5 male and 5 females) were 
exposed by inhalation for 6 hours/day, 5 days/week for 4 weeks and then 
held 28 additional days before sacrifice. Exposure was 0, 150, 600, or 
2,500 mg/m3 of ethyl lactate in the first study and 0, 25, 
75, or 200 milligram/milliliter (mg/mL) in the second study. For ethyl 
lactate the effects were noted at 600 mg/m3 and higher, 
primarily damage in the olfactory epithelium. The NOAEL was 200 mg/
m3.
    5. Animal metabolism. The in vitro hydrolysis of lactate esters 
(methyl, ethyl, butyl, pentyl, isoamyl, isopropyl, isobutyl, 2-
ethylhexyl) in rat olfactory epithelium homogenate has been evaluated. 
In general of the eight lactates evaluated, the rat nasal epithelium 
showed increased capacity to hydrolyze the lactates and increased 
affinity with increasing molecular weight (increase in alcohol chain 
length). Based on the similarity of effects and kinetic parameters it 
appears that lactic acid is most likely the cause of the lactate 
toxicity. An in vivo absorption and hydrolysis study in rats with ethyl 
lactate demonstrated 80% hydrolysis in rat plasma in 60 minutes at room 
temperature. Ethyl lactate was detected in the portal blood indicate 
partial absorption by the gut.
    6. Metabolite toxicology. Ethyl lactate is readily hydrolyzed to 
lactic acid and ethyl alcohol (both which are listed as inert 
ingredients exempt from requirements for tolerance - 40 CFR 180.1001). 
These breakdown products are also listed as synthetic flavoring 
substances (21 CFR 172.515). Lactic acid is a metabolic break down 
product of all lactates, It is a normal metabolite in humans and is 
found in or added to foods (21 CFR 172.515). Lactic acid oral 
LD50 in rats is 3,730 mg/kg. It is not active in mutagenic 
tests. It will produce skin and eye irritation at high concentrations. 
The sodium salt of lactic acid is used in cosmetics as a skin 
moisturizer and parental solutions in the pharmaceutical industry. 
Ethyl alcohol occurs naturally as a product of fermentation of 
carbohydrates. It is the primary alcohol in beer, wine and liquor and 
is found in certain foods and other beverages and is used as a favoring 
agent (21 CFR 172.515). It is used as a chemical intermediate and as a 
solvent in perfumers, cosmetics, adhesives, inks and preservatives. 
Ethyl alcohol oral LD50 in rats is 13,700 mg/kg. It is not 
active in mutagenic tests. It will produce mild skin irritation at high 
concentrations (dryness). It is a developmental hazard causing fetal 
alcohol syndrome in humans. Its primary acute effect in man is 
intoxication and narcosis. It can cause chronic liver damage.

B. Aggregate Exposure

    Non-dietary exposure. Ethyl lactate will be used in animal, pre-
harvest and post-harvest applications as a solvent, diluent, 
coalescence agent, surfactant and emulsifier at levels up to 50%. It 
will be applied, at a maximum of 2-3 times per crop. The low vapor 
pressure would tend to keep airborne exposure low.
