Executive Summary

Acute and chronic combined dietary (food + drinking water) exposure and
risk assessments were conducted using the Dietary Exposure Evaluation
Model DEEM-FCID™, Version 2.03 which use food consumption data from
the U.S. Department of Agriculture’s Continuing Surveys of Food
Intakes by Individuals (CSFII) from 1994-1996 and 1998.  The analyses
were performed to support Section 3 and Section 24(c) requests for uses
on swiss chard, bushberry Subgroup 13-07B, and strawberry.

The acute and chronic assessments are highly conservative with regard to
protecting human health.  Both assessments assume 100% crop treated and
are based on tolerance-level residues for all commodities.  Modeled
estimates of clopyralid residues in drinking water have been
incorporated into the analyses.  Children 1-2 years old are estimated to
have the highest dietary exposure to clopyralid.  The screening-level
estimates for that subpopulation are 9% of the acute population-adjusted
dose (aPAD) and 24% of the chronic population-adjusted dose (cPAD).
Generally, HED is concerned about dietary risk when the exposure
estimate exceeds 100% of the PAD.  Therefore, the combined dietary risk
from residues of clopyralid in food and drinking water are below HED’s
level of concern for all population groups.  There are no dietary
exposure considerations that would preclude granting the requested uses
of clopyralid.  An aggregate human health risk assessment is forthcoming
(DP No. D361316).

I.	Introduction

Dietary risk assessment incorporates both exposure and toxicity of a
given pesticide.  For acute and chronic assessments, the risk is
expressed as a percentage of a maximum acceptable dose (i.e., the dose
which HED has concluded will result in no unreasonable adverse health
effects).  This dose is referred to as the population adjusted dose
(PAD).  The PAD is equivalent to the point of departure (POD, NOAEL,
LOAEL, e.g.) divided by the required uncertainty or safety factors.

For acute and non-cancer chronic exposures, HED is concerned when
estimated dietary risk exceeds 100% of the PAD.  HED is generally
concerned when estimated cancer risk exceeds one in one million.
References which discuss the acute and chronic risk assessments in more
detail are available on the EPA/pesticides web site:  “Available
Information on Assessing Exposure from Pesticides, A User’s Guide,”
21-JUN-2000, web link:      HYPERLINK

http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf  ; or see
SOP 99.6 (20-AUG-1999).

The most recent dietary risk assessment for clopyralid was conducted by
D. Dotson (9 Sept 2002, D284780).

II.	Residue Information

Permanent tolerances are established for residues of clopyralid in/on a
wide variety of plant commodities at levels ranging from 0.5 ppm in/on
stone fruits to 500 ppm in/on grass forage and hay [40 CFR
§180.431(a)], including a tolerance of 1.0 ppm for strawberry.
Permanent tolerances are also established for residues of clopyralid in
livestock commodities at levels ranging from 0.1 ppm in eggs to 36 ppm
in meat byproducts, except liver, of cattle, goats, horses and sheep.
The residue of concern for both tolerance enforcement and risk
assessment is the parent compound only.

To support the petitioned-for uses, IR-4 has submitted residue data from
field trials with swiss chard, blueberry, and strawberry (depicting
residues following the annual production practice associated with the
regional registration request).  HED’s recommended tolerances for
these uses, derived from the NAFTA tolerance-harmonization spreadsheet,
are 3.0 ppm for swiss chard, 0.5 ppm for the bushberry subgroup, and 4.0
ppm for strawberry.  HED is recommending that the 4.0-ppm tolerance for
strawberry replace the existing 1.0-ppm tolerance.  Furthermore, HED is
recommending that the existing tolerance of 4.0 ppm for cranberry remain
in place, despite the fact that cranberry is a member of Crop Subgroup
13-07B.  This is due to differences in the use directions for cranberry
versus those for the subgroup in general.  These requested uses do not
impact existing tolerances for livestock commodities.

This is a screening-level assessment; therefore, tolerance-level
residues were used in the analyses along with default processing factors
from DEEM version 7.81.  It was also assumed that 100% of crops with
registered or requested uses of clopyralid were treated.  The inputs for
the dietary assessments are provided in Attachments 1 (acute assessment)
and 2 (chronic assessment).

 Drinking Water Data

The estimated drinking water concentrations (EDWCs) used in the dietary
risk assessment were provided by the Environmental Fate and Effects
Division (EFED) in the following memorandum: “Tier I Drinking Water
Assessment for Proposed New Use of Clopyralid on Swiss Chard, Bushberry
Subgroup 13-07B and Annual Strawberry” (A. Shelby, 9 September 2009,
D361314) and incorporated directly into this dietary assessment.  Water
residues were incorporated in the DEEM-FCID into the food categories
“water, direct, all sources” and “water, indirect, all sources.”

Modeled estimates of surface water from the FIRST model were used for
both the acute and chronic assessments (Table 1).  These estimates are
greater than those for groundwater via the SCIGROW model as well as the
monitoring data that are available for clopyralid.  The models and their
descriptions are available at the EPA internet site:   HYPERLINK
"http://www.epa.gov/oppefed1/models/water/"
http://www.epa.gov/oppefed1/models/water/ .

Table 1.  Estimated Drinking Water Concentrations for Clopyralid.

Drinking Water Source (Model Used)	Use (Rate Modeled)	Maximum Estimated
Drinking Water Concentration (EDWC), ppb

Groundwater (SCIGROW)	Bushberry (0.25 Lbs a.i./A)	Acute And Chronic	0.39

Groundwater (Monitoring)	NAWQA (Alabama)	Acute	13

Surface Water (FIRST)	Bushberry (0.25 Lbs a.i./A)	Acute	41.1

	Bushberry (0.25 Lbs a.i./A)	Chronic	10.8

	Non-crop (0.5 lb a.i./A)	Acute	45.0

	Non-crop (0.5 lb a.i./A)	Chronic	11.9

Surface Water (Monitoring)	NAWQA	Acute	42

For these assessments, the maximum EDWCs of 45 ppm (acute) and 11.9 ppm
(chronic) were used.  As noted in EFED’s evaluation, the monitoring
data are greater than some of the modeled estimates; especially for
groundwater.  HED believes that using the modeled estimates in the
dietary assessment is protective of human health since modeled values
are the maxima for their respective exposure durations.

IV.	DEEM-FCID™ Program and Consumption Information

Clopyralid acute and chronic dietary exposure assessments were conducted
using the Dietary Exposure Evaluation Model software with the Food
Commodity Intake Database DEEM-FCID™, Version 2.03 which incorporates
consumption data from USDA’s Continuing Surveys of Food Intakes by
Individuals (CSFII), 1994-1996 and 1998.  The 1994-96, 98 data are based
on the reported consumption of more than 20,000 individuals over two
non-consecutive survey days.  Foods “as consumed” (e.g., apple pie)
are linked to EPA-defined food commodities (e.g. apples, peeled fruit -
cooked; fresh or N/S; baked; or wheat flour - cooked; fresh or N/S,
baked) using publicly available recipe translation files developed
jointly by USDA/ARS and EPA.  For chronic exposure assessment,
consumption data are averaged for the entire U.S. population and within
population subgroups, but for acute exposure assessment are retained as
individual consumption events.  Based on analysis of the 1994-96, 98
CSFII consumption data, which took into account dietary patterns and
survey respondents, HED concluded that it is most appropriate to report
risk for the following population subgroups: the general U.S.
population, all infants (<1 year old), children 1-2, children 3-5,
children 6-12, youth 13-19, adults 20-49, females 13-49, and adults 50+
years old.

For chronic dietary exposure assessment, an estimate of the residue
level in each food or food-form (e.g., orange or orange juice) on the
food commodity residue list is multiplied by the average daily
consumption estimate for that food/food form to produce a residue intake
estimate.  The resulting residue intake estimate for each food/food form
is summed with the residue intake estimates for all other food/food
forms on the commodity residue list to arrive at the total average
estimated exposure.  Exposure is expressed in mg/kg body weight/day and
as a percent of the cPAD.  This procedure is performed for each
population subgroup.

For acute exposure assessments, individual one-day food consumption data
are used on an individual-by-individual basis.  The reported consumption
amounts of each food item can be multiplied by a residue point estimate
and summed to obtain a total daily pesticide exposure for a
deterministic exposure assessment, or “matched” in multiple random
pairings with residue values and then summed in a probabilistic
assessment.  The resulting distribution of exposures is expressed as a
percentage of the aPAD on both a user (i.e., only those who reported
eating relevant commodities/food forms) and a per-capita (i.e., those
who reported eating the relevant commodities as well as those who did
not) basis.  In accordance with HED policy, per capita exposure and risk
are reported for all tiers of analysis.  However, for tiers 1 and 2, any
significant differences in user vs. per capita exposure and risk are
specifically identified and noted in the risk assessment.

V.	Toxicological Information

The toxicology database for clopyralid is incomplete at this time.
Based on the toxicology data requirements outlined in the recently
revised 40 CFR Part 158, there are additional requirements for acute and
subchronic neurotoxicity studies in the rat (§870.6200a and b), and an
immunotoxicity study (§870.7800).  In addition, a 28-day inhalation
toxicity study in the rat (§870.3465) is required.  Nevertheless, HED
recommends reduction of the FQPA special factor to 1x.  There was no
evidence of increased pre- and/or postnatal qualitative or quantitative
susceptibility in the developmental rat or rabbit studies, or the rat
2-generation reproduction study.  In the developmental rat study, no
developmental effects were seen in at a dose that caused maternal
toxicity.  Although acute and subchronic neurotoxicity studies and an
immunotoxicity study have not been submitted and are required under the
revised 40 CFR Part 158 guidelines, the available subchronic and chronic
studies show no evidence of either neurotoxicity or immunotoxicity at
doses up to or exceeding the limit dose.  The endpoints selected for
risk assessment are therefore considered adequately protective of pre-
and/or postnatal toxicity.

The endpoints for use in dietary risk assessment are summarized in Table
2, below.

Point of Departure (POD) = A data point or an estimated point that is
derived from observed dose-response data and  used to mark the beginning
of extrapolation to determine risk associated with lower environmentally
relevant human exposures.  NOAEL = no observed adverse effect level.
LOAEL = lowest observed adverse effect level.  UF = uncertainty factor.
UFA = extrapolation from animal to human (interspecies).  UFH =
potential variation in sensitivity among members of the human population
(intraspecies).  FQPA SF = FQPA Safety Factor.  PAD = population

margin of exposure.  LOC = level of concern.  N/A = not applicable.

VI.	Results

As stated above, for acute and chronic assessments, HED is concerned
when dietary risk exceeds 100% of the PAD.  The DEEM-FCID™ analyses
estimate the dietary exposure of the U.S. population and various
population subgroups.  The results reported in Table 3 are for the
general U.S. Population, all infants (<1 year old), children 1-2,
children 3-5, children 6-12, youth 13-19, females 13-49, adults 20-49,
and adults 50+ years.  Risk estimates are below HED’s level of concern
for all population subgroups.

VII.	Characterization of Inputs/Outputs

Highly conservative, health-protective assumptions have been used
throughout the acute and chronic dietary assessments for clopyralid.
The resulting exposure and risk estimates likely overestimate any actual
dietary exposures to clopyralid that may occur due to the registered and
requested uses.

VIII.	Conclusions

Highly conservative assessments indicate that there are no acute or
chronic dietary (food + drinking water) exposure concerns for
clopyralid.  There are no dietary risk considerations that would
preclude granting the requested uses.  A full aggregate human health
risk assessment is forthcoming (D361316).
