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 
provided in Unit I. of the Supplementary Information. To ensure proper 
receipt by EPA, it is imperative that you identify docket ID number 
OPP-2002-0033 in the subject line on the first page of your response.

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.

XI. Codex Harmonization

    No Codex maximum residue levels (MRLs) have been established for 
propanil; therefore, issues of compatibility between Codex MRLs and 
U.S. tolerances do not exist.
