Propanil; Notice of Pesticide Tolerance Reassessment Decision and
Availability of Risk Assessments
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: This notice represents the Agency's tolerance reassessment
[[Page 38654]]
decision for propanil. It announces the Agency's tolerance reassessment
decision and releases the human health and ecological effects risk
assessments 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) indicates that propanil poses no
risk concerns; therefore, no risk mitigation is needed and no further
actions related to dietary risk are warranted at this time. The Agency
will complete a Reregistration Eligibility Decision (RED) document for
propanil later in 2002, which will address any possible risk to workers
and the environment and any confirmatory data needs.
DATES: Public comments on the tolerance reassessment decision for
propanil are requested on or before July 5, 2002. In the absence of
substantive comments, the tolerance reassessment decision will be
considered final. Comments on the human health and ecological effects
risk assessments must be submitted on or before August 5, 2002.
ADDRESSES: Comments, may be submitted by mail, electronically, or in
person. Please follow the detailed instructions for each method as

II. Tolerance Reassessment and Risk Management Decision
The Agency has completed its assessment of the dietary risk of
propanil (3',4'-dichloropropionanilide) and its principle metabolic
degradate 3,4-dichloroaniline (3,4-DCA), and has determined that the
level of dietary risk from exposure as a result of currently registered
uses of propanil is not of concern to the Agency. Therefore, no
mitigation measures are needed and no further actions are warranted at
this time. Tolerances for the registered uses of propanil are
reassessed. The Agency is still reviewing any possible risk to workers
and the environment and, if risk mitigation is necessary, the Agency
will provide its risk management decision, as well as any confirmatory
data requirements, in the RED scheduled for later in 2002.
The Agency may determine that further action is necessary, once it
is determined whether the anilides, such as propanil, share a common
mechanism of toxicity as a group or with other neuroendocrine-
disrupting chemicals. Such an incremental approach to the tolerance
reassessment process is consistent with the Agency's goal of improving
transparency in implementing FFDCA. For propanil, the established
tolerances remain in effect until such time as a full reassessment of
the cumulative risk from all anilide pesticides, such as propanil, may
be needed and is completed.
III. Background
This notice announces the tolerance reassessment decision for
propanil. This decision has been developed as part of the public
participation process that EPA and the United States Department of
Agriculture (USDA) are using to involve the public in the reassessment
of pesticide tolerances under FFDCA. EPA must review tolerances and
tolerance exemptions that were in effect when the Food Quality
Protection Act (FQPA) was enacted in August of 1996 to ensure that
these existing pesticide residue limits for food and feed commodities
meet the safety standard of the new law. Propanil was first registered
in 1973 and is therefore subject to both reregistration and tolerance
assessment under the FQPA amendments to FFDCA.
The FQPA amendments to FFDCA requires EPA to review all the
tolerances for registered chemicals in effect on or before the date of
the enactment. In reviewing these tolerances, the Agency must consider,
among other things, aggregate risks from nonoccupational sources of
pesticide exposure, whether there is increased susceptibility to
infants and children and the cumulative effects of pesticides with a
common mechanism of toxicity. The tolerances are considered reassessed
once the safety finding has been made or a revocation occurs.
FFDCA requires that the Agency, when considering whether to
establish, modify, or revoke a tolerance, consider ``available
information'' concerning the cumulative effects of a particular
pesticide's residues and ``other substances that have a common
mechanism of toxicity.'' The Agency does not have sufficient
information at this time to determine whether the anilide pesticides,
such as propanil, share a common mechanism of toxicity.
The Agency's human health findings for the pesticide propanil,
discussed in Unit IV., are presented fully in the document: ``Propanil-
HED Revised Human Health Risk Assessment, February 28, 2002.'' The risk
assessments and other documents pertaining to the propanil tolerance
reassessment decision are available for viewing in the public docket
(see Unit I.B.2.) or on the Agency's website at http://www.epa.gov/
pesticides/reregistration/status.htm.
IV. Use Summary
Propanil is a selective post-emergent herbicide registered on rice,
barley, oats, and spring wheat to control broadleaf and grass weeds in
commercial settings. Propanil is also registered (but not currently
marketed) for turf use at commercial sod farms. There are no existing
or proposed residential uses of propanil products.
Propanil is formulated as an emulsifiable concentrate liquid
(16.6%-58% active ingredient), a water dispersable granule (or dry
flowable) (59.6%-81% active ingredient), a soluble concentrate liquid
(41.2%-80.2% active ingredient), and a flowable concentrate (41.2%
active ingredient). Propanil is typically applied as a broadcast
treatment by groundboom sprayers and aerial equipment.
The estimate for total domestic use (annual average) is
approximately 7 million pounds of active ingredient on a total of
approximately 2 million acres treated. The crop with the highest use is
rice, which accounts for approximately 99% of the annual average. Fifty
to seventy percent of the U.S. rice crop is treated with propanil.
Small grains comprise the remaining 1% of the annual average.
V. Dietary Food Risks
EPA has not assessed acute dietary risk for propanil since no
appropriate endpoint attributable to a single exposure (dose) could be
identified. An acute dietary reference dose was not established.
Chronic dietary risk is calculated by using the average consumption
value for food and average residue values on those foods. A risk
estimate that is less than 100% of the chronic population adjusted dose
(cPAD), the dose at which an individual could be exposed over the
course of a lifetime and no adverse health effects would be expected,
does not exceed the Agency's level of concern. The cPAD is the chronic
dietary reference dose (RfD) adjusted for the FQPA safety factor.
Chronic risk estimates from exposures to propanil in food do not
exceed the Agency's level of concern (i.e., they are less than 100% of
the cPAD). The chronic dietary (food only) risk estimate is 13% of the
cPAD, for the most highly exposed population subgroup, all infants (<1
year).
The toxicity endpoint for the chronic dietary assessment is
decreased hemoglobin, red blood cell count and/or packed cell volumes
and is calculated using the lowest observed adverse effect level
(LOAEL) (9 milligrams/kilogram/day (mg/kg/day)) from the chronic/
carcinogenicity study in the rat (no observed adverse effect level
(NOAEL)) was identified).
The FQPA safety factor of 10x was retained for chronic exposures
based on increased susceptibility following prenatal and postnatal
exposure, the
[[Page 38656]]
lack of a developmental neurotoxicity study; and neuroendocrine
disruption in the rat. The uncertainty factor (UF) used in the RfD
derivation is 300x. The UF is 100x (10x for interspecies extrapolation
and 10x for intraspecies variability). An additional UF of 3x is
applied for the use of a LOAEL instead of a NOAEL for an overall UF of
3,000x. Thus, the chronic RfD is 0.03 mg/kg/day and the cPAD is 0.003
mg/kg/day.
The propanil chronic dietary exposure assessment was conducted
using the Dietary Exposure Evaluation Model (DEEM\TM\) Software Version
7.73. The DEEM\TM\ analysis evaluated the individual food consumption
as reported by respondents in the USDA's Continuing Surveys of Food
Intake by Individuals (CSFII), 1989-1992, and accumulated exposure to
the chemical for each commodity. To calculate chronic dietary risk from
propanil use on food, EPA used the DEEM\TM\, along with average residue
estimated from field trial data, and assumed 70% of the rice crop was
treated with propanil. Field trial data are generally considered to be
an upper-bound estimate of actual residues, and 70% is also a high-end
estimate of the percent of the present rice crop treated. Thus, actual
dietary risk is likely to be less than indicated by EPA's assessment.
Food and Drug Administration (FDA) monitoring data were available, but
not sufficient, due to lack of analysis for 3,4-DCA.
VI. Dietary Drinking Water Risks
Drinking water exposure to pesticides can occur through ground
water and surface water contamination. EPA considers both acute (1 day)
and chronic (lifetime) drinking water risks and uses either modeling or
actual monitoring data, if available, to estimate those risks. To
determine the maximum allowable contribution of water allowed in the
diet, EPA first looks at how much of the overall allowable risk is
contributed by food, then calculates a ``drinking water level of
comparison'' (DWLOC) to determine whether modeled or monitoring
estimates exceed this level. In the case of propanil, no acute drinking
water assessment has been conducted, because no acute endpoint was
identified. The calculated chronic DWLOCs for propanil are 26 parts per
billion (ppb) for children, 86 ppb for adult females, and 100 ppb for
adult males.
Available data indicate that propanil will not persist in the
environment and is in the medium mobility class for sand, sandy loam
and clay loam soils, based on available mobility studies. Due to its
mobility, propanil could possibly reach ground water but due to its
rapid metabolism in a water/soil matrix, it is unlikely to persist for
a sufficient amount of time to leach in significant quantities. (The
possible exception are sites of extreme vulnerability and low metabolic
capacity which would most likely occur only for terrestrial uses.
However, if propanil does reach ground water in these vulnerable areas,
it is expected to be stable). Propanil and its principle metabolic
degradate, 3,4-DCA, and residues convertible to 3,4-DCA are the
residues of concern for the drinking water risk assessment.
Monitoring data for propanil residues in ground water and surface
water are available but not adequate to develop estimated environmental
concentrations (EECs) for the aggregate dietary (food and water) risk
assessment. Although not targeted to specific propanil use areas,
United States Geological Survey (USGS) monitoring data do provide some
information on the magnitude and frequency of propanil and 3,4-DCA
detections. Propanil was found in about 3% of the 1,560 surface water
samples analyzed with a maximum concentration of 2 parts per billion
(ppb). 3,4-DCA was found in about 50% of the 68 samples with a maximum
concentration of 8.9 ppb. All detects are well below the DWLOCs. Models
have been used to estimate ground water and surface water
concentrations expected from normal agricultural use.
Estimated surface water EECs, a range of 6-72 ppb, are below the
DWLOC for all population subgroups except for children at the upper-
bound EEC of 72 ppb. This subpopulation of children could be an area of
concern because exposure estimates for this group exceed the DWLOC;
however, the Agency believes that the concerns have been addressed by
the conservative assumptions (field trial residue levels and 70% crop
treated) used in the chronic dietary calculation. In this case, the
Agency concludes that actual residues of propanil per se and 3,4-
dichloroaniline (3,4-DCA combined) are likely to be less than the
estimated DWLOC; and a conclusion can be drawn that no adverse
toxicological effect will occur due to aggregate chronic exposure.
Estimated drinking water concentrations are based on EPA's Pesticide
Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS)
screening model, which is a Tier II assessment that provides more
refined, less upper-bound assumptions. The range of EECs represents
different rice growing areas and normal versus overflow release.
Estimated ground water concentrations are based on the Screening
Concentration in Ground Water (SCI-GROW) model, which is a Tier I
assessment that provides a high-end estimate. The drinking water EEC
for ground water (0.35 ppb) is below the DWLOC for all population
subgroups.
VII. Aggregate Risks
The aggregate risk assessment for propanil examines the combined
risk from exposure through food and drinking water only. Chronic
residential exposures are not expected because there are no residential
uses for propanil and, thus, are not included in the aggregate risk
assessment. As detailed above, for propanil the only interval of
exposure to be assessed is chronic (1 year or more), and the only route
of exposure to be assessed is oral (food and water). Generally,
combined risks from these exposures that are less than 100% of the
cPAD, are not considered to be a risk concern.
EPA has also evaluated the potential aggregate exposure to 3,4-DCA.
Available data indicates that 3,4-DCA is a major metabolic degradate of
propanil. 3,4-DCA is also a metabolite of linuron and diuron, but to a
lesser extent. The Agency's Metabolism Assessment Review Committee does
not recommend aggregating residues of 3,4-DCA for the propanil,
linuron, and diuron risk assessments. 3,4-DCA is a significant residue
of concern for propanil, but is not a residue of concern per se for
linuron or diuron. Submitted data indicate that the maximum amount of
3,4-DCA formed from propanil is approximately 50% of propanil initially
applied, based on results from the aerobic soil metabolism study.
Neither diuron nor linuron metabolize to 3,4-DCA in appreciable amounts
(less than 1% detection rate) of the parent compound in animal, plant,
or water metabolism studies.
The registered uses for propanil, linuron, and diuron result in
minimal co-occurrence of use. That is, there is very little overlap of
use patterns and the use patterns are geographically limited for each
chemical. Therefore, the risk assessments for each individual chemical
fully assess the risks posed by the parent chemical and the metabolite,
3,4-DCA, individually.
VIII. Residential Risk
Propanil is not registered for residential (home) use, nor is it
used in or around public buildings, schools, or recreational areas
where children might be exposed. Thus, there is no residential exposure
to aggregate with the dietary exposure.
The use of propanil on turf is restricted to commercial sod farms
only. Although propanil-treated sod may
[[Page 38657]]
eventually be used in residential settings (i.e., residential lawns),
propanil residues are not expected to exceed levels of concern for
residential post-application risk. Since the proposed use of propanil
on turf is post-emergent, applied at sod farms early in the turf
growing season (well before harvest), the Agency concludes that the
amount of time is adequate to allow residue dissipation to a level that
would not pose any significant exposure to residents.
IX. Occupational Risk and Ecological Risk
The Agency will assess occupational and ecological risks, any
necessary mitigation as well as the need for confirmatory data in the
forthcoming RED.
X. Tolerance Reassessment Summary
The existing tolerances for residues of propanil in/on plant,
animal and processed commodities are established under 40 CFR
180.274(a)(1) and (a)(2). These tolerances are currently expressed as
the combined residues of propanil (3',4'-dichloropropionanilide) and
its metabolites (calculated as propanil). The Agency is now
recommending that the propanil tolerance expression for plant and
animal commodities be revised to specify that the residues of concern
are propanil and its related compounds convertible to 3,4-DCA. To
eliminate redundancy, the propanil tolerances separately listed under
40 CFR 180.274(a)(2) should be removed and 40 CFR 180.274(a)(1) should
be redesignated as 40 CFR 180.274(a).
The Agency has updated the list of raw agricultural and processed
commodities and feedstuffs derived from crops (Table 1, OPPTS GLN
860.1000). As a result of these changes, propanil tolerances for
certain raw agricultural commodities that have been removed from the
livestock feed table need to be revoked. A number of tolerances are
being revised (increased or decreased) to reflect updates to the
propanil data base based on the submission of new livestock feeding
studies, analytical methods, processing data, recovery methods, and/or
field trial residue data. Additionally, some commodity definitions must
be updated and/or corrected. A summary of propanil tolerance
reassessments is presented below in Table 1.
Adequate residue data have been submitted to support the
established tolerances for barley, grain; cattle, fat; goat, fat; hog,
fat; horse, fat; milk; oat, grain; poultry, meat; rice, straw; sheep,
fat; and wheat, straw. For these commodities, the established
tolerances were found to be appropriate and will not change as part of
this tolerance reassessment.
The established tolerance levels for barley, straw; oat, straw, and
wheat, straw must be increased to reflect new recovery procedures. The
established tolerance levels for cattle, meat byproducts; egg; goat,
meat byproducts; hog, meat byproducts; horse, meat byproducts; poultry,
meat byproducts, and sheep, meat byproducts have been increased based
on the results of livestock feeding studies and revised dietary burden
(exposure) to propanil. For rice, grain; rice, bran, and rice, hull,
the existing tolerance levels were increased since data demonstrate
that residues concentrate in bran and hulls when rice is processed,
based on a reevaluation of crop field trial data.
The available data indicate that the tolerance levels can be
decreased for cattle, meat; goat, meat; hog, meat; horse, meat;
poultry, fat; and sheep, meat based on the results of a ruminant
feeding study and a revised dietary burden.
Group commodity definitions will be revised as noted in Table 1.
The established tolerances for rice mill fractions and rice polishings
should be revoked according to Table 1 of OPPTS GLN 860.1000, since
these commodities are no longer considered to be significant livestock
feed items. As a result, the tolerances are no longer needed.
Tolerances To Be Proposed Under 40 CFR 180.274(a)
Adequate residue data have been submitted for the establishment of
propanil tolerances for crayfish; oat, forage, and wheat, forage based
on the crayfish metabolism study and wheat forage data.
Inadequate residue data are available for the establishment of
propanil tolerances for barley, hay; oat, hay, and wheat, hay. The
requested data for wheat, hay will be translated to barley, hay, and
oat, hay.
Tolerances Currently Listed Under 40 CFR 180.274(a)(2)
The tolerances currently listed in 40 CFR 180.274(a)(2) are
inadvertent duplicates of the tolerances established for the same
commodities listed in 40 CFR 180.274(a)(1). The tolerances listed in 40
CFR 180.274(a)(2) should be removed because the duplicate tolerances
found there are not needed.
