II. Petition for Tolerance
In the Federal Register of April 4, 2007 (72 FR 16352) (FRL-8119-
2), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
6E7152) by IR-4. The petition requested that 40 CFR 180.464 be amended
by establishing a tolerance for residues of the herbicide dimethenamid,
1 (R,S)-2-chloro-N-[(1-methyl-2-methoxy) ethyl]-N-(2,4-dimethylthien-3-
yl)-acetamide) in or on hop, dried cones at 0.05 parts per million
(ppm); pumpkin at 0.01 ppm; radish, roots at 0.01 ppm; radish, tops at
0.01 ppm; rutabaga, roots at 0.01 ppm; rutabaga, tops at 0.1 ppm;
turnip, greens at 0.1 ppm; turnip, roots at 0.01 ppm; turnip, tops at
0.1 ppm; and winter squash at 0.01 ppm. That notice referenced a
summary of the petition prepared by BASF Corporation, the registrant,
which is available to the public in the docket, http://www.regulations.gov.
There were no comments received in response to the
notice of filing.
Based upon review of the data supporting the petition, EPA has
approved regionally restricted tolerances for pumpkin and winter
[[Page 73628]]
squash for States of Oregon and Washington only, in that supporting
data are limited to EPA growing Region 12. The reason for these changes
is further explained in the supporting document for this action,
entitled, ``Dimethenamid-P. Petition for Registration for Uses Turnips
and Hops. Summary of Analytical Chemistry and Residue Data. Petition
6E7152,'' in docket ID number EPA-HQ-OPP-2007-0116.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean 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.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.'' These provisions were added to FFDCA by the Food Quality Protection
Act (FQPA) of 1996.
Consistent with section 408(b)(2)(D) of FFDCA, and the factors
specified in section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other relevant information in support of
this action. EPA has sufficient data to assess the hazards of and to
make a determination on aggregate exposure for the petitioned-for
tolerance for residues of dimethenamid on hop, dried cones at 0.05 ppm;
pumpkin at 0.01 ppm; radish, roots at 0.01 ppm; radish, tops at 0.01
ppm; rutabaga, roots at 0.01 ppm; rutabaga, tops at 0.1 ppm; turnip,
greens at 0.1 ppm; turnip, roots at 0.01 ppm; turnip, tops at 0.1 ppm;
and winter squash at 0.01 ppm. EPA's assessment of exposures and risks
associated with establishing the tolerance follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered the
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children. Specific information on the studies received and the nature
of the adverse effects caused by dimethenamid as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies can be found at http://www.regulations.gov.
The referenced document is available in the docket
established by this action, which is described under ADDRESSES, and is
identified as EPA-HQ-OPP-2007-0116 in that docket.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the toxicological level of concern (LOC) is derived
from the highest dose at which no adverse effects are observed (the
NOAEL) in the toxicology study identified as appropriate for use in
risk assessment. However, if a NOAEL cannot be determined, the lowest
dose at which adverse effects of concern are identified (the LOAEL) is
sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the LOC to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
risks by comparing aggregate exposure to the pesticide to the acute
population adjusted dose (aPAD) and chronic population adjusted dose
(cPAD). The aPAD and cPAD are calculated by dividing the LOC by all
applicable UFs. Short-, intermediate-, and long-term risks are
evaluated by comparing aggregate exposure to the LOC to ensure that the
margin of exposure (MOE) called for by the product of all applicable
UFs is not exceeded.
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk and estimates risk in terms
of the probability of occurrence of additional adverse cases.
Generally, cancer risks are considered non-threshold. For more
information on the general principles EPA uses in risk characterization
and a complete description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm
.
A summary of the toxicological endpoints for dimethenamid used for
human risk assessment can be found at http://www.regulations.gov in
document, ``Dimethenamid-P. Amended Human Health Risk Assessment for a
Proposal for the Establishment of Tolerances for Dimethenamid-P Use on
Winter Squash, Pumpkin, Radish (Roots and Tops), Rutabaga (Roots and
Tops), Turnip (Roots, Tops and Greens) and on Hops, Dried Cones,'' at
docket ID number EPA-HQ-OPP-2007-0116.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to dimethenamid, EPA considered exposure under the petitioned-
for tolerances as well as all existing dimethenamid tolerances in (40
CFR 180.464). EPA assessed dietary exposures from dimethenamid in food
as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure.
In estimating acute dietary exposure, EPA used Dietary Exposure
Evaluation Model/Food Consumption Intake Database (DEEM/FCID) Version
2.03 which incorporates food consumption information from the U.S.
Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide
Continuing Surveys of Food Intake by Individuals (CSFII). An
appropriate acute endpoint attributable to a single dose was selected
for the population subgroup females 13-49. The acute dietary analysis
was conducted for dimethenamid assuming tolerance level residues,
default processing factors, and 100% crop treated (CT) information.
ii. Chronic exposure. In conducting the chronic dietary exposure
(food and drinking water assessment), EPA used consumption data from
the USDA 1994-1996 and 1998 Nationwide CSFII. The chronic dietary
exposure assessment was conducted for dimethenamid assuming tolerance
level residues, default processing factors, and 100%CT information.
iii. Cancer. Dimethenamid is a category ``C'' possible human
carcinogen. The chronic reference dose (cRfD) of 0.05 milligram/
kilogram/day (mg/kg/day) used for risk assessment is based on non-
cancer precursor effects in the liver; therefore, the cRfD is
considered protective of both cancer and non-cancer effects. A separate
cancer exposure assessment was not performed.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring data to complete a comprehensive dietary exposure
[[Page 73629]]
analysis and risk assessment for dimethenamid in drinking water.
Because the Agency does not have comprehensive monitoring data,
drinking water concentration estimates are made by reliance on
simulation or modeling taking into account data on the environmental
fate characteristics of dimethenamid. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at http://www.epa.gov/oppefed1/models/water/index.htm.
Based on the EPA's Pesticide Root Zone Model/Exposure Analysis
Modeling System (PRZM/EXAMS) and Screening Concentration in Ground
Water (SCI-GROW) models, the estimated drinking water concentrations
(EDWCs) of dimethenamid for acute exposures are estimated to be 66.7
parts per billion (ppb) for surface water and 1.0 ppb for ground water.
The EDWCs for chronic exposures are estimated to be 20.2 ppb for
surface water and 1.0 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. The EDWCs for use sites with
the highest values were used. For acute dietary risk assessment, the
water concentration value of 66.7 ppb was used to assess the
contribution to drinking water. For chronic dietary risk assessment,
the water concentration of value 20.2 ppb was used to assess the
contribution to drinking water.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets).
Dimethenamid is not registered for use on any sites that would
result in residential exposure.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to dimethenamid and any other
substances and dimethenamid does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that dimethenamid has
a common mechanism of toxicity with other substances. For information
regarding EPA's efforts to determine which chemicals have a common
mechanism of toxicity and to evaluate the cumulative effects of such
chemicals, see EPA's website at http://www.epa.gov/pesticides/cumulative
.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional (``10X'') tenfold margin of safety for infants and
children in the case of threshold effects to account for prenatal and
postnatal toxicity and the completeness of the database on toxicity and
exposure unless EPA determines based on reliable data that a different
margin of safety will be safe for infants and children. This additional
margin of safety is commonly referred to as the FQPA safety factor. In
applying this provision, EPA either retains the default value of 10X
when reliable data do not support the choice of a different factor, or,
if reliable data are available, EPA uses a different additional FQPA
safety factor value based on the use of traditional UFs and/or special
FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. There is no concern for
increased qualitative and/or quantitative susceptibility following
prenatal and postnatal exposure to dimethenamid in rats and rabbits. In
the developmental toxicity study in rats there was an increased
incidence of post-implantation loss and minor skeletal variations. In
the developmental toxicity study in rabbits, late resorptions and minor
skeletal variations were observed at the highest dose tested. In the
rabbit, the developmental effects occurred at the same dose as maternal
toxicity; whereas in the rat, the developmental effects occurred at
much higher doses than in the dams. The reproduction study showed
decreases in body weight in both pups and parental animals at the same
dose levels.
3. Conclusion. EPA has determined that reliable data show that it
would be safe for infants and children to reduce the FQPA safety factor
to 1X. That decision is based on the following findings:
i. The toxicity database for dimethenamid is complete.
ii. There is no indication that dimethenamid is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is no evidence that dimethenamid results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100%CT and tolerance-level residues which results in very high-end
estimates of dietary exposure. The dietary drinking water assessment
utilizes values generated by modeland associated modeling parameters
which are designed to provide health protective, high-end estimates of
water concentrations. These assessments will not underestimate the
exposure and risks posed by dimethenamid.
E. Aggregate Risks and Determination of Safety
Safety is assessed for acute and chronic risks by comparing
aggregate exposure to the pesticide to the aPAD and cPAD. The aPAD and
cPAD are calculated by dividing the LOC by all applicable UFs. For
linear cancer risks, EPA calculates the probability of additional
cancer cases given aggregate exposure. Short-, intermediate-, and long-
term risks are evaluated by comparing aggregate exposure to the LOC to
ensure that the MOE called for by the product of all applicable UFs is
not exceeded.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to dimethenamid will occupy < 1 % of the aPAD at the 95th percentile for
females 13-49 years old, the population group of concern for acute
dimethenamid exposure.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
dimethenamid from food and water will utilize 3% of the cPAD for all
infants (< 1 year old), the subpopulation group with greatest exposure.
There are no residential uses for dimethenamid that result in chronic
residential exposure to dimethenamid.
3. Short-term risk. Short-term aggregate exposure takes into
account residential exposure plus chronic exposure to food and water
(considered to be a background exposure level). Dimethenamid is not
registered for use on any sites that would result in residential
exposure. Therefore, the aggregate risk is the sum of the risk from
food and water, which do not exceed the Agency's level of concern
(LOC). A
[[Page 73630]]
short-term aggregate risk assessment is not required.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account residential exposure plus chronic exposure to food
and water (considered to be a background exposure level).
Dimethenamid is not registered for use on any sites that would
result in residential exposure. Therefore, the aggregate risk is the
sum of the risk from food and water, which do not exceed the Agency's
level of concern. An intermediate-term aggregate risk assessment is not
required.
5. Aggregate cancer risk for U.S. population. The chronic reference
dose (cRfD) of 0.05 mg/kg/day used for risk assessment is based on non-
cancer precursor effects in the liver; therefore, the cRfD and chronic
risk assessment are considered protective of both cancer and non-cancer
effects.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population or to infants and children from aggregate
exposure to dimethenamid residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography with a
nitrogen phosphorus detector (GC/NPD) Method AM-0884-0193-1) is
available to enforce the tolerance expression. The method may be
requested from: Chief, Analytical Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone
number: (410) 305-2905; e-mail address: residuemethods@epa.gov.
B. International Residue Limits
There are no established or proposed Codex, Canadian or Mexican
maximum residue limits (MRLs) for dimethenamid on any of the crops/
commodities being proposed in this petition.
V. Conclusion
Therefore, tolerances are established for residues of the herbicide
dimethenamid, 1 (R,S)-2-chloro-N-[(1-methyl-2-methoxy) ethyl]-N-(2,4-
dimethylthien-3-yl)-acetamide) in or on hop, dried cones at 0.05 parts
per million (ppm); pumpkin at 0.01 ppm; radish, roots at 0.01 ppm;
radish, tops at 0.01 ppm; rutabaga, roots at 0.01 ppm; rutabaga, tops
at 0.1 ppm; turnip, greens at 0.1 ppm; turnip, roots at 0.01 ppm;
turnip, tops at 0.1 ppm; and winter squash at 0.01 ppm. The existing
time-limited tolerance for winter squash shall be deleted as a
permanent tolerance is being established by this action.
VI. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this rule has been
exempted from review under Executive Order 12866, this rule is not
subject to Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355,
May 22, 2001) or Executive Order 13045, entitled Protection of Children
from Environmental Health Risks and Safety Risks (62 FR 19885, April
23, 1997). This final rule does not contain any information collections
subject to OMB approval under the Paperwork Reduction Act (PRA), 44
U.S.C. 3501 et seq., nor does it require any special considerations
under Executive Order 12898, entitled Federal Actions to Address
Environmental Justice in Minority Populations and Low-Income
Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 6, 2000) do not apply to this rule. In addition, This
rule does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
of 1995 (UMRA) (Public Law 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
