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 
6E7168) by Interregional Research Project Number 4 (IR-4), 500 College 
Road East, Suite 201 W, Princeton, NJ 08540. The petition requested 
that 40 CFR 180.535 be amended by establishing tolerances for combined 
residues of the herbicide fluroxypyr, 1-methylheptyl ester [1-
methylheptyl ((4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy)acetate] 
and its metabolite fluroxypyr [((4-amino-3,5-dichloro-6-fluoro-2-
pyridinyl)oxy)acetic acid], in or on pome, fruit, group 11 at 0.02 
parts per million (ppm); millet, grain at 0.5 ppm; millet, forage at 
12.0 ppm; millet, hay at 20.0 ppm; millet, proso, grain at 0.5 ppm; 
millet, proso, straw at 12.0 ppm; millet, proso, forage at 12.0 ppm; 
millet, proso, hay at 20.0 ppm; millet, pearl, grain at 0.5 ppm; 
millet, pearl, forage at 12.0 ppm; and millet, pearl, hay at 20.0 ppm. 
That notice referenced a summary of the petition prepared by Dow 
AgroSciences, the registrant, which is available to the public in the 
docket, https://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 
determined that separate tolerances for proso and pearl millet grain, 
forage, and hay are not needed since these commodities are covered by 
the tolerances being established for millet grain, millet forage and 
millet hay.
    EPA is also deleting all the tolerances in Sec.  180.535(b) for 
field and sweet corn, onion, and sorghum commodities that are no longer 
needed since they have expired. The deletions under Sec.  180.535(b) 
are time-limited tolerances that were established under section 18 
emergency exemptions that have since expired and have been superceded 
by the establishment of general tolerances for the same commodities 
under Sec.  180.535(a).

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 combined residues of fluroxypyr, 1-methylheptyl ester [1-
methylheptyl ((4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy)acetate] 
and its metabolite fluroxypyr [((4-amino-3,5-dichloro-6-fluoro-2-
pyridinyl)oxy)acetic acid] on fruit, pome, group 11 at 0.02 ppm; 
millet, grain at 0.5 ppm; millet, forage at 12.0 ppm; millet, hay at 
20.0 ppm and millet, proso, straw at 12.0 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 fluroxypyr as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studiescan be found at https://
www.regulations.gov in document Fluroxypyr: Human Health Risk 
Assessment to Support Proposed New Uses on Pome Fruits and Millet at 
Attachment 2 page 27 - 30 in docket ID number EPA-HQ-OPP-2007-
0114.
    Fluroxypyr has low acute toxicity by the oral and dermal routes and 
moderate acute toxicity by the inhalation route. The kidney is the 
target organ for fluroxypyr following oral exposure to rats, mice, and 
dogs. In the rat, increased kidney weight and death were observed in 
both sexes in the 90-day feeding study, increased kidney weight and 
chronic progressive glomerulonephropathy were observed in both sexes in 
the chronic study. Increased kidney weight was observed in the maternal 
rat in the developmental toxicity study, and kidney effects (deaths due 
to renal failure; increased kidney weight, and microscopic kidney 
lesions) were observed in both sexes in the 2-generation reproduction 
study. Although kidney toxicity (early signs of acute tubular 
nephrosis) was observed in dogs in the 28-day feeding study, no kidney 
effects or other treatment related toxicity was seen in the chronic 
feeding study in dogs. Increased kidney lesions (increased incidences 
of renal papillary necrosis and regenerative nephrosis in females) were 
observed in mice following long-term exposure. Treatment related deaths 
were noted in maternal rats (600 milligrams/kilograms/day (mg/kg/day)) 
and rabbits (400 mg/kg/day). Endpoints for risk assessment were based 
on kidney effects seen in the database. There was no evidence of 
increased susceptibility (quantitative/qualitative) following in utero 
exposure to the acid and the ester in rats and rabbits, or following 
prenatal and/or postnatal exposure in rats. There are no neurotoxicity 
concerns from the acute and subchronic neurotoxicity studies, and the 
weight of the evidence indicates a lack of concern for developmental 
neurotoxicity. Therefore, a developmental neurotoxicity study (DNT) is 
not required. Fluroxypyr is classified as ``not likely'' as a human 
carcinogen and there was no concern for its mutagenicity potential.

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

[[Page 73633]]

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 https://
www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
    A summary of the toxicological endpoints for fluroxypyr used for 
human risk assessment can be found at https://www.regulations.gov in 
document Fluroxypyr: Human Health Risk Assessment to Support Proposed 
New Uses on Pome Fruits and Millet at page 11 in docket ID number EPA-
HQ-OPP-2007-0114.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to fluroxypyr, EPA considered exposure from the petitioned-for 
tolerances as well as all existing fluroxypyr tolerances in (40 CFR 
180.535). EPA assessed dietary exposures from fluroxypyr 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 single exposure.
    No such effects were identified in the toxicological studies for 
fluroxypyr; therefore, a quantitative acute dietary exposure assessment 
is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 1994-1996 
and 1998 Nationwide Continuing Surveys of Food Intake by Individuals 
(CSFII). As to residue levels in food, assumed all foods for which 
there are tolerances were treated and contain tolerance-level residues.
    iii. Cancer. Based on the results of carcinogenicity studies in 
rats and mice, EPA has concluded that fluroxypyr is ``not likely to be 
carcinogenic to humans.'' Consequently, a quantitative cancer exposure 
and risk assessment is not appropriate for fluroxypyr.
    2. Dietary exposure from drinking water. The Agency lacks 
sufficient monitoring data to complete a comprehensive dietary exposure 
analysis and risk assessment for fluroxypyr 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 
fluroxypyr. Further information regarding EPA drinking water models 
used in pesticide exposure assessment can be found at https://
www.epa.gov/oppefed1/models/water/index.htm.
    Based on the Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS) and Screening Concentration in Groundwater (SCI-
GROW) models, the estimated environmental concentrations (EECs) of 
fluroxypyr for chronic exposures are estimated to be 3.28 ppb for 
surface water and 0.04 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration value of 3.28 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).
    Fluroxypyr is currently registered for the following residential 
non-dietary sites: Application to residential turf grass and 
recreational sites such as golf courses, parks, and sports fields. EPA 
assessed residential exposure using the following assumptions:
    Residential handlers may receive short-term dermal and inhalation 
exposure to fluroxypyr when mixing, loading and applying the 
formulations. However, toxicity by the dermal route of exposure is not 
expected; therefore only inhalation daily doses for residential 
handlers were calculated. Adults and children may be exposed to 
fluroxypyr residues from dermal contact with turf during post-
application activities. Toddlers may receive short- and intermediate-
term oral exposure from incidental ingestion during post-application 
activities. A dermal risk assessment for post-application exposures was 
not conducted because a dermal endpoint was not selected. Therefore, 
only the following post-application exposure scenarios resulting from 
lawn treatment were assessed:
    i. Toddlers' incidental ingestion of pesticide residues on lawns 
from hand-to-mouth transfer,
    ii. Object-to-mouth transfer from mouthing of pesticide-treated 
turfgrass, and
    iii. Incidental ingestion of soil from pesticide-treated 
residential areas.
    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 fluroxypyr and any other 
substances and fluroxypyr 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 fluroxypyr 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 https://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

[[Page 73634]]

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 was no evidence of 
increased susceptibility (quantitative/qualitative) following in utero 
exposure to the fluroxypyr in rats and rabbits, or following prenatal 
and/or postnatal exposure in rats. There are no neurotoxicity concerns 
from the acute and subchronic neurotoxicity studies, and the weight of 
the evidence indicates a lack of concern for developmental 
neurotoxicity.
    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 fluroxypyr is complete.
    ii. There is no indication that fluroxypyr 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 fluroxypyr 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% crop treated and tolerance-level residues. Conservative ground 
and surface water modeling estimates were used. EPA used similarly 
conservative assumptions to assess post-application exposure of 
children as well as incidental oral exposure of toddlers. These 
assessments will not underestimate the exposure and risks posed by 
fluroxypyr.

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. None of the toxicology studies available for 
fluroxypyr indicated the possibility of an effect of concern occurring 
as a result of a single exposure; therefore, fluroxypyr is not expected 
to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that exposure to 
fluroxypyr from food and water will utilize 1.4% of the cPAD for 
children 1-2 years old, the subpopulation group with greatest exposure. 
Based on the use patterns, chronic residential exposure to residues of 
fluroxypyr is not expected.
    3. Short-term risk and intermediate-term. Short-term and 
intermediate-term aggregate exposure takes into account residential 
exposure plus chronic exposure to food and water (considered to be a 
background exposure level).
    Fluroxypyr is currently registered for uses that could result in 
short-term and intermediate-term residential exposure and the Agency 
has determined that it is appropriate to aggregate chronic food and 
water and short-term exposures for fluroxypyr.
    Using the exposure assumptions described in this unit for short-
term and intermediate-term exposures, EPA has concluded that food, 
water, and residential exposures aggregated result in aggregate MOEs of 
4,400 to 53,000. The MOE for the U.S. population is 8,200. The most 
highly exposed subgroup was Children, 1-2 years old, with an MOE of 
4,400.
    4. Aggregate cancer risk for U.S. population. There was no evidence 
of carcinogenicity in two carcinogenicity studies in rats and mice with 
fluroxypyr. Therefore, fluroxypyr is considered ``Not likely to be 
carcinogenic to humans.'' Fluroxypyr is not expected to pose a cancer 
risk.
    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, or to infants and children from aggregate 
exposure to fluroxypyr residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (gas chromatography/mass-selective 
detector (GC/MSD)) 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 Codex, Canadian or Mexican MRLs for fluroxypyr for 
pome fruits or millet.

V. Conclusion

    Therefore, tolerances are established for combined residues of 
fluroxypyr, 1-methylheptyl ester [1-methylheptyl ((4-amino-3,5-
dichloro-6-fluoro-2-pyridinyl)oxy)acetate] and its metabolite 
fluroxypyr [((4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy)acetic 
acid] in or on fruit, pome, group 11 at 0.02 ppm; millet, grain at 0.5 
ppm; millet, forage at 12.0 ppm; millet, hay at 20.0 ppm and millet, 
proso, straw at 12.0 ppm.
    Time-limited tolerances were established in 40 CFR 180.535(b) for 
residues of fluroxypyr on field and sweet corn, onion, and sorghum 
commodities in connection with FIFRA section 18 emergency exemptions 
granted by the EPA. All of these time-limited tolerances have expired 
and are no longer in force. Permanent tolerances have been established 
on these commodities in Sec.  180.535(a). Because expired, time-limited 
tolerances for residues of fluroxypyr are without effect, this final 
rule removes them from EPA's regulations. EPA finds there is good cause 
to make this latter change without prior notice and comment because it 
eliminates obsolete portions of the regulation. EPA concludes notice 
and comment are unnecessary on such changes.

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

[[Page 73635]]

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
