II. Background and Statutory Findings
In the Federal Register of March 22, 2006 (71 FR 14521) (FRL-7766-
7), 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
4E6844) by Interregional Research Project No. 4 (IR-4), Technology
Center of New Jersey, Rutgers, the State University of New Jersey, 681
U.S. Highway 1 South, North Brunswick, NJ 08902-3390. The
petition requested that 40 CFR 180.464 be amended by establishing a
tolerance for residues of the herbicide dimethenamid, (R,S)-2-chloro-N-
[(1-methyl-2-methoxy) ethyl]-N-(2,4-dimethylthien-3-yl)-acetamide in or
on the raw agricultural commodities: onion, green at 0.01 parts per
million (ppm); leek at 0.01 ppm; onion, Welsh at 0.01 ppm; and shallot,
fresh leaves at 0.01 ppm. That notice included a summary of the
petition prepared by BASF Corporation, the registrant. There were no
comments received in response to the notice of filing.
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....''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm
.
III. Aggregate Risk Assessment and Determination of Safety
Consistent with 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, consistent with section
408(b)(2) of FFDCA, for a tolerance for residues of dimethenamid,
(R,S)-2-chloro-N-(1-methyl-2-methoxy) ethyl-N-(2,4-dimethylthien-3-yl)-
acetamide in or on the raw agricultural commodities: onion, green at
0.01 ppm; leek at 0.01 ppm; onion, Welsh at 0.01 ppm; and shallot,
fresh leaves 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 its
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 toxic 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.epa.gov/fedrgstr/EPA-PEST/2004/September/Day-24/p21501.htm
.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the dose at which no adverse effects are observed
(the NOAEL) from the toxicology study identified as appropriate for use
in risk assessment is used to estimate the toxicological level of
concern (LOC). However, the lowest dose at which adverse effects of
concern are identified (the LOAEL) is sometimes used for risk
assessment if no NOAEL was achieved in the toxicology study selected.
An uncertainty factor (UF) is applied to reflect 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.
The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify non-threshold hazards such as
cancer. The Q* approach assumes that any amount of exposure will lead
to some degree of cancer risk, estimates risk in terms of the
probability of occurrence of additional cancer cases. More information
can be found on the general principles EPA uses in risk
characterization at http://www.epa.gov/pesticides/health/human.htm.
A summary of the toxicological endpoints for dimethenamid used for
human risk assessment is discussed in Unit III.B. of the final rule
published in the Federal Register of September 24, 2004 (69 FR 57197)
(FRL-7680-1).
[[Page 49352]]
C. Exposure Assessment
1. Dietary exposure from food and feed uses. Tolerances have been
established (40 CFR 180.464) for the residues of dimethenamid in or on
a variety of raw agricultural commodities. Risk assessments were
conducted by EPA to assess dietary exposures from chemical name 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 one-day or single exposure.
The Dietary Exposure Evaluation Model software with the Food
Commodity Intake Database (DEEM-FCID\TM\, Version 1.3) which
incorporates food consumption data as reported by respondents in the
USDA 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by
Individuals (CSFII), and accumulated exposure to the chemical for each
commodity. The following assumptions were made for the acute exposure
assessments: one hundred percent of proposed and registered crops are
treated with dimethenamid (100% CT) and tolerance-level residues for
all commodities.
ii. Chronic exposure.
In conducting the chronic dietary exposure assessment EPA used the
Dietary Exposure Evaluation Model software with the Food Commodity
Intake Database (DEEM-FCID\TM\, Version 1.3) which incorporates food
consumption data as reported by respondents in the USDA 1994-1996 and
1998 Nationwide Continuing Surveys of Food Intake by Individuals
(CSFII), and accumulated exposure to the chemical for each commodity.
The following assumptions were made for the chronic exposure
assessments: one hundred percent of proposed and registered crops are
treated with dimethenamid (100% CT) and tolerance-level residues for
all commodities
iii. Cancer. Dimethenamid (50:50 S:R isomers) was classified as a
group < < C'' (possible human carcinogen). The Agency concluded that the
chronic risk assessment, making use of the cPAD, to be protective of
any potential carcinogenic risk. Therefore, the exposure estimates for
food and water discussed in Unit III.C.1.ii and III.C.2. for chronic
exposures were also used to assess cancer. Dimethenamid could be
considered a weak carcinogen. An intermediate dose showed marginally
significant results (p = 0.056) with liver adenomas one species (rat)
and one sex (males). The incidence of liver tumors was just slightly
increased from the level in the historical control data. Higher doses
did not demonstrate the occurrence of liver adenomas significantly
different from the controls. No dose-related tumors were seen in the
mouse carcinogenicity study, and a battery of mutagenicity studies with
dimethenamid-P (90:10 S:R isomers) were negative or equivocal for
genetic mutations including unscheduled DNA synthesis.
2. Dietary exposure from drinking water.
The Agency lacks sufficient monitoring exposure data to complete a
comprehensive dietary exposure 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 physical 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 PRZM/EXAMS and SCI-GROW models, the estimated
environmental concentrations (EECs) of dimethenamid for acute exposures
are estimated to be 49 parts per billion (ppb) for surface water and
0.42 ppb for ground water. The EECs for chronic exposures are estimated
to be 7.9 ppb for surface water and 0.42 ppb for ground water.Modeled
estimates of drinking water concentrations were directly entered into
the dietary exposure model (DEEM-FCID\TM\, Version 1.3). For acute
dietary risk assessment, the peak water concentration value of 49 ppb
was used to access the contribution to drinking water. For chronic
dietary risk assessment, the annual average concentration of 7.9 ppb
was used to access 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 the 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 the policy statements released by EPA's Office of
Pesticide Programs concerning common mechanism determinations and
procedures for cumulating effects from substances found to have a
common mechanism on 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 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 data base on toxicity and exposure
unless EPA determines based on reliable data that a different margin of
safety will be safe for infants and children. Margins of safety are
incorporated into EPA risk assessments either directly through use of a
MOE analysis or through using uncertainty (safety) factors in
calculating a dose level that poses no appreciable risk to humans. 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 safety
factor value based on the use of traditional uncertainty factors and/or
special FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. No offspring pre- or
postnatal susceptibility to either dimethenamid (50:50 S:R isomers) or
dimethenamid-P (90:10 S:R isomers) was seen in a rabbit or two rat
developmental studies and reproduction study. There is low concern for
pre- or postnatal toxicity since the developmental effects from the
[[Page 49353]]
[S] and [RS] mixture are similar and occur at similar doses.
3. Conclusion. There is a complete toxicity data base for
dimethenamid and exposure data are complete or are estimated based on
data that reasonably accounts for potential exposures.
EPA determined that the safety factor for dimethenamid should be
100 (10X safety factor for interspecies extrapolation and 10X for
intraspecies variation). The additional FQPA SF was removed taking into
account the low concerns and lack residual uncertainties with regard to
prenatal and postnatal toxicity and the completeness of the toxicity
and exposure data base.
E. Aggregate Risks and Determination of Safety
The Agency currently has two ways to estimate total aggregate
exposure to a pesticide from food, drinking water, and residential
uses. First, a screening assessment can be used, in which the Agency
calculates drinking water levels of comparison (DWLOCs) which are used
as a point of comparison against estimated drinking water
concentrations (EDWCs). The DWLOC values are not regulatory standards
for drinking water, but are theoretical upper limits on a pesticide's
concentration in drinking water in light of total aggregate exposure to
a pesticide in food and residential uses. More information on the use
of DWLOCs in dietary aggregate risk assessments can be found at http://www.epa.gov/
[fxsp0]oppfead1/trac/[fxsp0]science/
[fxsp0]screeningsop.pdfMore recently the Agency has used another
approach to estimate aggregate exposure through food, residential and
drinking water pathways. In this approach, modeled surface and ground
water EDWCs are directly incorporated into the dietary exposure
analysis, along with food. This provides a more realistic estimate of
exposure because actual body weights and water consumption from the
CSFII are used. The combined food and water exposures are then added to
estimated exposure from residential sources to calculate aggregate
risks. The resulting exposure and risk estimates are still considered
to be high end, due to the assumptions used in developing drinking
water modeling inputs.
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 for females 13 years and
older. Therefore, EPA does not expect the aggregate exposure to exceed
100% of the aPAD.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
dimethenamid food and water will utilize < 1 % of the cPAD for the U.S.
population, 1.2 % of the cPAD for all infants < 1 year old, the
subpopulation at greatest exposure, and < 1 % of the cPAD for children
1-2 years old. There are no residential uses for dimethenamid.
Therefore, EPA does not expect the aggregate exposure to exceed 100% of
the cPAD.
3. Short-term and Intermediate-term risk.
Short-term and Intermediate-term aggregate exposures take 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.
4. Aggregate cancer risk for U.S. population. The Agency considers
the chronic aggregate risk assessment, making use of the cPAD, to be
protective of any aggregate cancer risk. See Unit III.E.2.
5. 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, and to infants and children from aggregate
exposure to dimethenamid residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (AM-0884-0193-1) is available to
enforce the tolerance expression. AM-0884-0193-1 is a gas
chromatography (GC) method using an HP-1 or HP-5 column and mass
selective detection (MSD). 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 Codex, Canadian, or Mexican MRLs for dimethenamid in
or on the proposed commodities. Therefore, harmonization of tolerances
is not an issue.
V. Conclusion
Therefore, tolerance are established for residues of dimethenamid,
(R,S)-2-chloro-N-[(1-methyl-2-methoxy) ethyl]-N-(2,4-dimethylthien-3-
yl)-acetamide in or on the commodities onion, green at 0.01 ppm; leek
at 0.01 ppm; onion, Welsh at 0.01 ppm; and shallot, fresh leaves at
0.01 ppm.
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 due to its lack of
significance, 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). 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., or 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). 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); or OMB review or any Agency action under Executive
Order 13045, entitled Protection of Children from Environmental Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, entitled Federalism
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to
develop an accountable process to ensure ``meaningful and timely input
by State and local officials in the development of regulatory policies
that
[[Page 49354]]
have federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. This action
does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. For these same reasons, the Agency has
determined that this rule does not have any ``tribal implications'' as
described in Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000). Executive Order 13175, requires EPA to develop an accountable
process to ensure ``meaningful and timely input by tribal officials in
the development of regulatory policies that have tribal implications.''
``Policies that have tribal implications'' is defined in the Executive
order to include regulations that have ``substantial direct effects on
one or more Indian tribes, on the relationship between the Federal
Government and the Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.''
This rule will not have substantial direct effects on tribal
governments, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this rule.
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
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).
