ENVIRONMENTAL PROTECTION AGENCY

[OPP-34255; FRL-6860-6]


Urea; Notice of Pesticide Report on FQPA Tolerance Reassessment 
Progress

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice constitutes the Agency's report on the Food 
Quality Protection Act (FQPA) tolerance reassessment progress for urea, 
announces the Agency's tolerance reassessment decision, and releases 
the science assessment for tolerance reassessment decision and related 
documents supporting this decision to the public. The Agency's 
reassessment of dietary risk, including public exposure through food 
and drinking water as required by the Federal Food, Drug, and Cosmetic 
Act (FFDCA) as amended by FQPA, indicates that urea poses no risk 
concerns within the limits of the existing exemptions; therefore, no 
risk mitigation is needed. There will be no changes to the 78 urea 
exemptions from the requirement of a tolerance as a result of this 
reassessment decision. EPA views this action as noncontroversial and 
anticipates no adverse comments. By law, EPA is required by August 2002 
to reassess 66% of the tolerances in existence on August 2, 1996, or 
about 6,400 tolerances. EPA is counting 78 exemptions from the 
requirement of a tolerance as reassessments made toward the August 2002 
review deadline.

DATES: Comments, identified by docket control number OPP-34255, must be 
received on or before May 15, 2002.

ADDRESSES: Comments may be submitted by mail, electronically, or in 
person. Please follow the detailed instructions for each method as

III. Report on FQPA Tolerance Reassessment Progress

    A new registration for urea was approved on August 23, 1995, with 
an approved label date of February 20, 1996, for use as an active 
ingredient (frost protectant) to reduce ice formation by ice-nucleating 
bacteria which are naturally present on leaf surfaces. Tolerance 
exemptions associated with that frost protectant use are codified in 40 
CFR 180.1117. Exemptions associated with uses of urea as an inert 
ingredient in pesticide formulations applied to growing crops or to raw 
agricultural commodities after harvest, in pesticide formulations 
applied to growing crops only, and in pesticide formulations applied to 
animals are codified in 40 CFR 180.1001(c), (d), and (e), respectively. 
Therefore, exemptions associated with use of urea as an active and 
inert ingredient are subject to reassessment in accordance with FFDCA 
as amended by FQPA. FQPA requires EPA to re-evaluate existing 
tolerances/exemptions to ensure that children and other sensitive 
subpopulations are protected from pesticide risk.
    The Agency has completed its assessment of the dietary risk of 
urea, and has determined that the level of dietary risk from exposure 
as a result of the currently registered uses of urea is not of concern. 
Therefore, no mitigation measures are needed and no further actions are 
warranted at this time. Urea does not pose unreasonable adverse effects 
to the environment when used according to its approved labeling. In 
addition, EPA finds that there is a reasonable certainty that no harm 
will result from aggregate exposure to the urea residue, including all 
anticipated dietary exposures and all other exposures for which there 
is reliable information. EPA considers a total of 78 exemptions from 
the requirement of a tolerance, 75 exemptions in 40 CFR 180.1117 and 3 
exemptions in 180.1001, to be reassessed under FQPA. All of those 78 
exemptions were found to meet the FQPA safety standard.
    The risk assessment and other documents pertaining to the 
reassessment of the urea exemptions from a requirement of a tolerance 
are available on the Internet at http://www.epa.gov/pesticides/reregistration/status.htm and the public docket for viewing (see Unit 
I.B.2).
    This notice of a tolerance reassessment for urea starts a 30-day 
public comment period during which the public is encouraged to submit 
comments on the Agency's risk assessment and tolerance exemption 
reassessment. The Agency is providing an opportunity, through this 
notice, for interested parties to comment in accordance with procedures 
described in Unit II. of this document. All comments will be carefully 
considered by the Agency. If any comment causes the Agency to revise 
its decision on reassessment of these exemptions from the requirement 
of a tolerance, EPA will publish notice of its amendment in the Federal 
Register.
    The legal authority for tolerance reassessment is provided by 
FFDCA, as amended in 1996. Section 408(q) of FFDCA directs that:
    The Administrator shall review tolerances and exemptions for 
pesticide chemical residues in effect on the day before the date of 
the enactment of the FQPA of 1996, as expeditiously as practicable, 
assuring that--66% of such tolerances and exemptions are reviewed 
within 6 years (i.e., by August 3, 2002) of the date of enactment of 
such Act (i.e., on August 3, 1996), and--shall determine whether the 
tolerance or exemption meets the requirements of sections 408(b)(2) 
or (c)(2) and shall, by the deadline for the review of the tolerance 
or exemption, issue a regulation under section 408(d)(4) or (e)(1) 
to modify or revoke the tolerance or revoke the tolerance or 
exemption if the tolerance or exemption does not meet such 
requirements.

Under section 408 of the FFDCA, a tolerance may only be maintained if 
EPA determines that the tolerance is safe based on a number of factors, 
including an assessment of the aggregate exposure to the pesticide and 
an assessment of the cumulative effects of such pesticide and other 
substances that have a common mechanism of toxicity. In section 
408(b)(2), the term ``safe,'' with respect to a tolerance for a 
pesticide chemical residue, means that the Administrator has determined 
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.

IV. Background

    Urea is an active ingredient in only one active registration, where 
it is used

[[Page 18199]]

as a frost protectant. The exemptions associated with urea use as a 
frost protectant are found at 40 CFR 180.1117. For counting purposes, 
there are 75 commodities exempt from the requirement of a tolerance 
(squash, winter and summer, counts as two; cotton counts as three 
because it also includes hay and seed; and casaba, crenshaw, and 
persian melon, count as one entry).
    Urea is also present in certain pesticide formulations as an inert 
ingredient where it is used as a stabilizer, an inhibitor, and as an 
adjuvant/intensifier for herbicides. One exemption for urea from the 
requirement of a tolerance when used as a stabilizer or inhibitor is 
found in 40 CFR 180.1001(c) for inert (or occasionally active) 
ingredients in pesticide formulations applied to growing crops or to 
raw agricultural commodities after harvest. Another exemption for urea 
when used as an adjuvant/intensifier for herbicides is found in 40 CFR 
180.1001(d) for inert (or occasionally active) ingredients in pesticide 
formulations applied to growing crops only. In addition, an exemption 
for urea when used as a stabilizer or inhibitor is found in 40 CFR 
180.1001(e) for inert (or occasionally active) ingredients in pesticide 
formulations applied to animals.
    Urea is a naturally occurring compound in humans and is approved 
for several therapeutic uses in humans with relatively few toxicities. 
In addition, urea is considered Generally Recognized As Safe (GRAS) by 
the U.S. Food and Drug Administration (FDA) for use in food. Urea is 
included in ``Direct Food Substances Affirmed as Generally Recognized 
as Safe'' (21 CFR 184.1923), where the affirmation of GRAS as a direct 
human food ingredient is based on current good manufacturing practice 
and conditions of use as a formulation and fermentation aid.
    EPA has reaffirmed data waivers granted for all subchronic, 
chronic, developmental, reproduction, mutagenicity, and metabolism 
studies based on available data from literature studies concerning 
urea. A recent search of the published scientific literature concerning 
urea since 1980 showed no basis for toxicological concern.

V. Use Summary

    Urea was registered by EPA in 1995 for use as a frost protectant 
pesticide under the trade name Enfrost. Enfrost is a 43% liquid 
formulation of urea that can be applied commercially to a wide variety 
of field crops, vegetables, fruit trees and ornamentals to reduce frost 
damage. There are currently no residential uses for urea as a pesticide 
product. Enfrost is the only currently registered pesticide product 
containing urea as an active ingredient. Enfrost provides frost 
protection by modifying the protein produced by ice-nucleating 
bacteria. Enfrost has not been actively produced or sold by the 
registrant, Entek Corporation, since 1995. However, the registrant 
wishes to maintain active registration of Enfrost for potential future 
production and use.
    In addition to its use as a frost protectant, urea is used as an 
inert pesticide ingredient as a stabilizer, inhibitor, or intensifier. 
Also, several million tons of urea are produced annually for use in 
fertilizer and as an animal feed supplement. Moreover, urea is used in 
the manufacture of dyes, fire retardant paints, plasticizers, and 
stabilizers for explosives.

VI. Hazard Characterization

    With the exception of six acute toxicity studies submitted by the 
registrant, the urea toxicity data base is comprised of the available 
literature data. These data are considered by the Agency to be 
sufficient to assess the potential hazard to humans, including special 
sensitivity of infants and children.
    1. Acute toxicity. The six acute toxicological studies indicate 
that the frost protectorant is a slight eye irritant and has a low 
toxicity to animals when administered via the oral, dermal, or 
inhalation routes of exposure.
    2. Subchronic toxicity. Urea produced no severe toxicity in dogs 
injected subcutaneously with 30-40 milliliters/kilograms/day (mL/kg/
day) of 10% urea solution for 45 days. With plasma levels ranging from 
200-700 mg/100 mL (10 to 30-fold above normal), the only clinical 
symptoms observed were drowsiness and diuresis. Necropsy indicated no 
adverse organ pathology.
    3. Chronic toxicity and carcinogenicity. Animal studies provide no 
evidence of adverse chronic or carcinogenic effects. One year feeding 
studies in male and female C57B1/6 mice and Fisher 344 rats reported no 
evidence of treatment-related cancer at doses up to 4.5% of the diet. 
Studies in the susceptible mouse strain (Strain A) also indicate no 
evidence of urea tumorigenicity.
    4. Developmental and reproductive toxicity. In a developmental 
toxicity study, pregnant Wistar rats produced healthy offspring with no 
reported evidence of teratogenic effects. A study of pregnant cows 
receiving 0.44 grams/kilograms urea showed no effects on reproductive 
performance nor were the calves affected.
    Urea has also been evaluated in monkeys for its ability to induce 
abortion. The mode of action is similar to the hyperosmolar effect of 
large doses of hypertonic saline and dextrose. However, such high 
intrauterine exposures would not be expected to occur from exposure to 
urea used as a frost protectant or inert pesticide ingredient. Urea is 
currently classified by FDA in category C for therapeutic use, ``Safety 
for use during pregnancy has not been established.''
    5. Absorption, metabolism, and excretion. Urea is extremely soluble 
in water and oral doses are rapidly absorbed and distributed in humans. 
Urea is a normal human body constituent and is constantly being 
produced through amino acid and protein metabolism where urea is formed 
through a cyclic mechanism.
    Urea has long been used as a dietary supplement for ruminants as a 
source of nitrogen for protein synthesis. Urea nitrogen can also 
contribute part of the amino acid requirements in humans. Utilization 
of urea nitrogen has been demonstrated both in malnourished children 
and adults.
    6. Therapeutic uses. Urea is approved for several therapeutic uses 
in humans with relatively few toxicities. Urea is used primarily as an 
osmotic agent for inducing diuresis and reducing intraoccular and 
intracranial pressure. Urea has also been used as a topical anesthetic 
for the treatment of mouth and throat inflammation (10-15% urea gel, 
liquid or solution), to debride necrotic and infected tissues, i.e. 
fingernails and toenails. It is also used in the treatment of sickle-
cell anemia and to ammoniate dentrifices as well as a basic ingredient 
in the synthesis of medically important compounds such as barbiturates 
and urethanes.
    7. FQPA considerations. EPA evaluated the available hazard and 
exposure data for urea and concluded that the data provide no 
indication of increased sensitivity of infants and children from 
exposure to urea. Due to the expected low toxicity of urea, the Agency 
has not used a safety factor analysis to assess the risk. For the same 
reasons, the additional ten-fold (FQPA 10X) safety factor to account 
for enhanced sensitivity of infants and children is not necessary.

VII. Exposure Assessment

    Based on the hazard assessment of urea, exposures to this compound 
resulting from reasonably anticipated patterns of usage present a 
reasonable certainty of no harm to human health. Given the low toxicity 
of urea, a more detailed assessment of risks resulting

[[Page 18200]]

from exposure to urea, when used either as a frost protectant or 
pesticide inert ingredient, is not necessary.

VIII. Environmental Fate and Transport

    Available data from literature reviews show that urea degrades 
rapidly in most soils, generally hydrolyzed to ammonium through soil 
urease activity. In various soils, the hydrolysis may near completion 
within 24 hours; however, the rate of hydrolysis can be much slower 
depending upon soil type, moisture content, and urea formulation. Soil 
adsorption studies show that urea adsorbs very weakly to soil; 
therefore, leaching is possible. Ultimate urea degradation produces 
ammonia and carbon dioxide as volatile products. Biodegradation is 
expected to be the major fate process in the aquatic ecosystem. The 
rate of biodegradation generally decreases with decreasing 
temperatures. Naturally-occurring phytoplankton increases the 
degradation rate because phytoplankton use urea as a nitrogen source. 
In phytoplankton-rich waters, degradation occurs much faster in 
sunlight than in the dark. Abiotic hydrolysis of urea occurs very 
slowly in relation to biotic hydrolysis.

IX. Summary of Risk Assessment Findings

    From the available animal studies and other data, EPA has concluded 
that urea exhibits a low toxicity and exposures to urea used either as 
an active or inert pesticide ingredient present a reasonable certainty 
of no harm to human health. The Agency's analysis of extensive 
toxicological data in numerous species supports the 1995 decision to 
grant permanent exemptions from the requirement of a tolerance for 
residues of the frost protectant when used before harvest in the 
production of raw agricultural commodities.

X. Tolerance Reassessment Summary

    Based on reevaluation of existing data, EPA believes there is 
sufficient basis to maintain exemption from the requirement of a 
tolerance for residues of the frost protectant urea when used before 
harvest in the production of the raw agricultural commodities listed in 
40 CFR 180.1117 and inert uses of urea listed in 40 CFR 180.1001.
