II. Petition for Tolerance
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 the FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
0F6138) by Interregional Research Project No. 4 (IR-4), Technology
Center of New Jersey, Rutgers, the State 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 in or on grass, forage at
0.05 parts per million (ppm); grass, hay at 0.30 ppm; grass, straw at
0.01 ppm; and grass, seed screenings 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 on review of the residue data, the EPA
determined that the tolerance for dimethenamid in or on grass, forage
at should be established at 0.15 ppm instead of 0.05 ppm requested by
the registrant, and the tolerance for grass, hay should be established
at 2.5 ppm instead of 0.30 ppm as requested by the registrant.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of the 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 the 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 the 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 the FFDCA by the Food
Quality Protection Act (FQPA) of 1996.
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in section 408(b)(2)(D), 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 in or on grass, forage at 0.15 parts per
million (ppm); grass, hay at 2.5 ppm; grass, straw at 0.01 ppm; and
grass, seed screenings at 0.01
[[Page 44386]]
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 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 in the
document ``Dimethenamid-P Human Health Risk Assessment for Proposed Use
on Grasses Grown for Seed, PC Codes: 120051 and 129051, Petition No:
0F6138, DP Num: 337887''. The document is available at http://www.regulations.gov.
in the docket established by this action, which is
described under ADDRESSES, and is identified as EPA-HQ-OPP-2006-0165 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 (UF) 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 uncertainty/safety factors. Short-term, intermediate-
term, 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 uncertainty/safety factors 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 Human Health Risk Assessment for Proposed Use on
Grasses Grown for Seed, PC Codes: 120051 and 129051, Petition No:
0F6138, DP Num: 337887'' on page 16 in Docket ID EPA-HQ-OPP-2006-0165.
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 (R,S)-2-chloro-N-[(1-
methyl-2-methoxy) ethyl]-N-(2,4-dimethylthien-3-yl)-acetamide 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 food consumption information from the United States
Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide
Continuing Surveys of Food Intake by Individuals (CSFII). As to residue
levels in food, EPA assumed all foods for which there are tolerances
were treated and contain tolerance-level residues.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 Nationwide CSFII. As to residue levels in food, EPA assumed
all foods for which there are tolerances were treated and contain
tolerance-level residues.
iii. Cancer. Dimethenamid was classified as Group C - possible
human carcinogen based on benign liver tumors (males) in rats. EPA
determined that the chronic Reference dose (cRfD) would be protective
of any cancer risk posed by dimethenamid because the cRfD of 0.05
milligrams/kilogram/day (mg/kg/day) used for risk assessment is based
on non-cancer precursor effects in the liver. In making this
determination, EPA also took into account that the tumor incidences
were only slightly above historical control levels, only showed
statistical significance as increased trends and not by pairwise
between control and treated animals, only evidenced a statistically
significant trend when benign and malignant tumors were combined, and
were only seen in one species. Therefore, the cRfD is considered
protective of both non-cancer and cancer effects.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring 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 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 9.0
parts per billion (ppb) for surface water and 0.34 ppb for ground
water. The EDWCs for chronic exposures are estimated to be 3.8 ppb for
surface water and 0.34 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. The EDWCs for use sites (other
than grasses grown for seed) with the highest values were used. For
acute dietary risk assessment, the water concentration value of 66.7
ppb was used to access the contribution to drinking water. For chronic
dietary risk assessment, the water concentration of value 20.2 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.
[[Page 44387]]
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 EPA's website at http://www.epa.gov/pesticides/cumulative
.
D. Safety Factor for Infants and Children
1. In general. Section 408 of the 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 uncertainty/safety
factors 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 pre-
and post-natal exposure to the (RS) or (S) dimethenamid technical
products 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. The toxicity data showed no increase in qualitative and/or
quantitative susceptibility in fetuses and pups with in utero and pre-
and post-natal exposure.
iii. There is no evidence that dimethenamid is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional uncertainty factors to account for neurotoxicity.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessment utilizes proposed
tolerance level residues and 100% crop treated information for all
commodities, which results in very high-end estimates of dietary
exposure. The dietary drinking water assessment utilizes values
generated by model and associated modeling parameters which are
designed to provide health protective, high-end estimates of water
concentrations.
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. For linear
cancer risks, EPA calculates the probability of additional cancer cases
given aggregate exposure. Short-term, intermediate-term, 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
uncertainty/safety factors 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 for the population group
(women ages 13-49) receiving the greatest 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 the
population group (all infants (< 1 year)) receiving the greatest
exposure. There are no residential uses for dimethenamid that result in
chronic residential exposure to dimethenamid.
3. Short-term risk. 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.
4. Intermediate-term risk. 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 LOC.
5. Aggregate cancer risk for U.S. population. The cRfD of 0.05 mg/
kg/day used for risk assessment is based on non-cancer precursor
effects. Therefore, the cRfD is considered protective of both non-
cancer and cancer effects. Consequently, a separate aggregate cancer
risk assessment was not conducted.
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
An International Residue Limit (IRL) Status Sheet is appended to
the Dimethenamid-P Human Health Risk Assessment located in the docket
for this notice. Codex has established maximum residue limits (MRLs),
expressed in terms of dimethenamid-P and its enantiomer, for various
crop commodities but not for grass commodities. Canada and Mexico have
also established MRLs for dimethenamid-P and its enantiomer in/on
various crop commodities but not for grass, hay; grass, forage; grass,
straw; or grass, seed screenings.
V. Conclusion
Therefore, the tolerance is established for residues of
dimethenamid, in or on grass, forage at 0.15 ppm; grass, hay at 2.5
ppm; grass, straw at 0.01 ppm; and grass, seed screenings at 0.01 ppm.
[[Page 44388]]
VI. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of the
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 the 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).
