II. Summary of Petitioned-for Tolerances

    In the Federal Register of December 30, 2011 (76 FR 82238) (FRL-
9331-1), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
1F7928) by Dow AgroSciences LLC, 9330 Zionsville Road, Indianapolis, IN 
46268. The petition requested that 40 CFR 180.535 be amended by 
establishing tolerances for residues of the herbicide, fluroxypyr 1-MHE 
and its acid metabolite, fluroxypyr, in or on rice at 1.5 parts per 
million (ppm) and rice bran at 3.0 ppm. That document referenced a 
summary of the petition prepared by Dow AgroSciences LLC, the 
registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the 
notice of filing.

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 * * 
*.''
    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA 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 fluroxypyr including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with fluroxypyr 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.
    The active ingredient used in formulating end-use herbicide 
products is fluroxypyr 1-methylheptyl ester. However, since the ester 
form has been shown to rapidly hydrolyze to the acid form, the residues 
of fluroxypyr 1-methylheptyl ester along with its fluroxypyr acid 
metabolite (free and conjugated), are collectively expressed as 
``fluroxypyr'' and are therefore regulated together for tolerance 
enforcement. In terms of toxicity, the ester and acid forms are 
considered the same.
    Fluroxypyr has low acute toxicity by the oral and dermal routes of 
exposure and moderate to mild acute toxicity by the inhalation route of 
exposure, based on lethality studies. Fluroxypyr is not a dermal 
sensitizer, nor is it irritating to the skin; however, it is a mild eye 
irritant.
    The kidney is the target organ for fluroxypyr following oral 
exposure to rats, mice, and dogs. In the rat, increased kidney weight, 
nephrotoxicity, and death were observed in both sexes in the 90-day 
feeding study, and increased kidney weight and microscopic kidney 
lesions were observed in both sexes in the chronic study. Increased 
kidney weight was also observed in maternal rats 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 in rats. Although 
microscopic kidney lesions were observed in dogs in the 28-day feeding 
study, no kidney effects or other treatment related toxicity were seen 
in the chronic feeding study in dogs at the same doses used in the 28-
day study. Microscopic kidney lesions were observed in mice following 
long-term exposure.
    There was no evidence of increased susceptibility (quantitative/
qualitative) following in utero exposure in rats and rabbits, or 
following pre and/or postnatal exposure in rats. Neither developmental 
toxicity nor reproductive toxicity was observed in rats. In rabbits, 
developmental toxicity was not observed following exposure to dose 
levels that resulted in maternal death; however, abortions were 
observed in rabbits following exposure to fluroxypyr at the limit dose. 
There was no evidence of neurotoxicity or neuropathology in any of the 
studies. An immunotoxicity study in rats found no indication of 
immunotoxicity. Fluroxypyr is classified ``not likely to be 
carcinogenic to humans'' due to lack of evidence to suggest 
carcinogenicity in the database, and there is no concern for its 
mutagenicity potential.
    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 studies can be found at http://www.regulations.gov in document ``Fluroxypyr. Human Health Risk 
Assessment to Support Proposed New

[[Page 3330]]

Use on Rice,'' p. 15 in docket ID number EPA-HQ-OPP-2011-0962.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. 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/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for fluroxypyr used for 
human risk assessment is shown in the Table of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to fluroxypyr, EPA considered exposure under 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 1-day or 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 U.S. Department 
of Agriculture's National Health and Nutrition Examination Survey, 
``What We Eat in America'' (NHANES/WWEIA) dietary survey conducted in 
2003-2008. As to residue levels in food, EPA assumed tolerance-level 
residues with 100 percent crop treated (PCT) for all existing and 
proposed crop uses and default processing factors for processed 
commodities.
    iii. Cancer. EPA has concluded that fluroxypyr does not pose a 
cancer risk to humans. Therefore, a dietary exposure assessment for the 
purpose of assessing cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue and/or PCT information in the dietary assessment 
for fluroxypyr. Tolerance level residues and 100 PCT were assumed for 
all food commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for fluroxypyr in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of fluroxypyr. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at

[[Page 3331]]

http://www.epa.gov/oppefed1/models/water/index.htm.
    Based on the Tier 1 Rice Model and Screening Concentration in 
Ground Water (SCI-GROW) models, the estimated drinking water 
concentrations (EDWCs) of fluroxypyr for acute and chronic exposures 
are both estimated to be 540 parts per billion (ppb) for surface water 
and 0.055 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For acute and chronic dietary 
risk assessment, the water concentration value of 540 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 uses that 
could result in residential exposures: Residential turfgrass, golf 
courses, parks and sports fields. EPA assessed residential exposure 
using the following assumptions: Residential handler exposure is 
expected to be short-term. Intermediate-term exposures are not likely 
because of the intermittent nature of applications by homeowners. Since 
there are no toxicity findings for the short-term dermal route of 
exposure up to the limit dose, only inhalation exposure was assessed 
for residential handlers of fluroxypyr. The following exposure 
scenarios were assessed for residential handlers: Loading and applying 
liquids with manually pressurized hand-wands, hose-end sprayers, and 
backpack applicators.
    For residential post-application exposure and risk estimates, EPA 
assumed that young children 1 to http://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
    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.'' EPA has not found 
fluroxypyr to share a common mechanism of toxicity with 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 assumed that fluroxypyr does not 
have 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 Web site at http://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) 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 (SF). In applying this provision, EPA either retains the default 
value of 10X, or uses a different additional safety factor when 
reliable data available to EPA support the choice of a different 
factor.
    2. Prenatal and postnatal sensitivity. There is no evidence of 
increased qualitative or quantitative susceptibility following in utero 
exposure in rats and rabbits or following pre and/or postnatal exposure 
in rats.
    Fluroxypyr is neither a developmental nor a reproductive toxicant 
in rats. Fluroxypyr has been evaluated for potential developmental 
effects in the rat and rabbit (gavage administration). Maternal 
toxicity included death in rats and rabbits. There were no 
developmental effects in the rat, and while abortions were observed in 
the rabbit, they occurred only at the limit dose.
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced 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 chronic dietary food exposure assessment utilizes 
tolerance level residue estimates and assumes 100 PCT for all 
commodities. This assessment will not underestimate exposure/risk. EPA 
made conservative (protective) assumptions in the ground and surface 
water modeling used to assess exposure to fluroxypyr in drinking water. 
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

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer given the 
estimated aggregate exposure. Short-, intermediate-, and chronic-term 
risks are evaluated by comparing the estimated aggregate food, water, 
and residential exposure to the appropriate PODs to ensure that an 
adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. 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 chronic exposure to 
fluroxypyr

[[Page 3332]]

from food and water will utilize 3.5% of the cPAD for all infants (electron 
capture detection (GC/ECD methods GRM 96.02 and 96.03)) are available 
to enforce the tolerance expression. Fluroxypyr was previously tested 
through FDA's Multiresidue Methodology, Protocols C, D, and E and was 
found to be recovered. The results have been published in the FDA 
Pesticide Analytical Manual, Volume I. The GRM 96.02 and 96.03 methods

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    There are no Maximum Residue Limits (MRLs) established by Codex, 
Canada, or Mexico for any of the proposed commodities for fluroxypyr.

V. Conclusion

    Therefore, tolerances are established for the combined residues of 
fluroxypyr 1-MHE and its acid metabolite fluroxypyr, in or on rice at 
1.5 ppm and rice bran at 3.0 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under FFDCA section 408(d) 
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 final rule has 
been exempted from review under Executive Order 12866, this final rule 
is not subject to Executive Order 13211, entitled ``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 FFDCA section 408(d), 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 FFDCA section 408(n)(4). 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 9, 2000) do not apply to this final rule. In addition, 
this final 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) (2 U.S.C. 1501 et seq.).
    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) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
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 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).

2. In Sec.  180.535, in paragraph (a), revise the introductory text and 
add alphabetically the following commodities to the table to read as 
follows:

Sec.  180.535  Fluroxypyr 1-methylheptyl ester; tolerances for 
residues.

    (a) General. 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 the 
following raw agricultural commodities. Compliance with the established 
tolerance levels is determined by measuring only the sum 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] calculated as the 
stoichiometric equivalent of fluroxypyr.
