II. Summary of Petitioned-for Tolerance

    In the Federal Register of November 7, 2012 (77 FR 66781) (FRL-
9367-5) (EPA-HQ-OPP-2012-0775), 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 2E8065) by BASF Corporation, 26 Davis Dr., P.O.
Box 13528, Research Triangle Park, NC 27709-3528. The petition
requested that 40 CFR 180.649 be amended by establishing tolerances for
residues of the herbicide, saflufenacil, including its metabolites and
degradates, in or on sugarcane, cane at 0.03 parts per million (ppm);
sugarcane, molasses at 0.075 ppm; and sugarcane, refined sugar at 0.045
ppm. That document referenced a summary of the petition prepared by
BASF Corporation, the registrant, which is available in the docket,
http://www.regulations.gov. There were no comments received in response
to the notice of filing.
    In the Federal Register of February 27, 2013 (78 FR 13295) (FRL-
9380-2) (EPA-HQ-OPP-2013-0008), 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 2F8139) by BASF Corporation, 26 Davis Dr., P.O.
Box 13528, Research Triangle Park, NC 27709-3528. The petition
requested that 40 CFR 180.649 be amended by establishing tolerances for
residues of the herbicide, saflufenacil, including its metabolites and
degradates, in or on crayfish at 0.01 ppm. In the Federal Register of
December 30, 2013 (78 FR 79359) (FRL-9903-69) (EPA-HQ-OPP-2013-0008)
EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3), announcing a revision to the original pesticide petition
(PP 2F8139) by BASF Corporation, 26 Davis Dr., P.O. Box 13528, Research
Triangle Park, NC 27709-3528. The revised petition requested that 40
CFR 180.649 be amended by establishing tolerances for residues of the
herbicide, saflufenacil, including its metabolites and degradates, in
or on fish-freshwater finfish and fish-shellfish crustacean at 0.01 ppm
instead of ``crayfish at 0.01 ppm'' based on the Agency's evaluation of
the data supporting the original petition. That document referenced a
summary of the petition prepared by BASF Corporation, the registrant,
which is available in the docket, http://www.regulations.gov. There
were no comments received in response to the notice of filing.
    In the Federal Register of June 5, 2013 (78 FR 33785) (FRL-9386-2)
(EPA-HQ-OPP-2013-0008), 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 2F8129) by BASF Corporation, 26 Davis Dr., P.O. Box 13528,
Research Triangle Park, NC 27709-3528. The petition requested that 40
CFR 180.649 be amended by amending tolerances for residues of the
herbicide, saflufenacil, including its metabolites and degradates, in
or on rice, straw at 0.30 ppm and amend the current commodity
definition ``Grain, cereal, forage, fodder and straw group 16'' to
``Grain, cereal, forage, fodder and straw group 16 (except rice
straw).'' That document referenced a summary of the petition prepared
by BASF Corporation, the registrant, which is available 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 petitions, EPA has
determined that the tolerance level of 0.03 ppm requested for
sugarcane, cane is increased to 0.05 ppm; and the tolerance level of
0.075 ppm requested for sugarcane, molasses is increased to 0.08 ppm.
Additionally, tolerances requested for sugarcane, refined sugar and
rice, straw are not being established at this time. The reasons for
these changes are explained in Unit IV.C.

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 saflufenacil including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with saflufenacil 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.
    Saflufenacil has low acute toxicity via all routes of exposure.
Subchronic and

chronic toxicity studies in rats, mice, and dogs identified the
hematopoietic system as the primary target of saflufenacil. Consistent
with its proposed mode of toxicity involving protoporphyrinogen IX
oxidase (PPO) inhibition and subsequent disruption of heme
biosynthesis, decreased hematological parameters were seen at about the
same dose level [lowest-observed adverse-effect levels (LOAELs) of 13-
39 milligram/kilogram/day (mg/kg/day)] across species, except in the
case of the dog, where the effects were seen at a slightly higher dose
(LOAELs of 50-100 mg/kg/day). These effects occurred around the same
dose level from short- through long-term exposures without increasing
in severity. In line with findings that male rats achieve a greater
systemic exposure than females, males were the most sensitive sex in
mice and rats. Effects were also seen in the liver (increased weight,
centrilobular fatty change, lymphoid infiltrate) in mice, the spleen
(increased spleen weight and extramedullary hematopoiesis) in rats, and
in both of these organs (increased iron storage in the liver and
extramedullary hematopoiesis in the spleen) in dogs. These effects also
occurred around the same dose level from short- through long-term
exposures without increasing in severity.
    Increased fetal susceptibility was observed in the developmental
toxicity studies in the rat and rabbit and in the 2-generation
reproduction study in the rat. Developmental effects (decreased fetal
body weights and increased skeletal variations in rats and increased
liver porphyrins in rabbits) occurred at doses that were not maternally
toxic, indicating increased quantitative susceptibility. In the 2-
generation reproductive toxicity study in rats, the reported offspring
effects were more severe than the maternal effects at the same dose
level, indicating evidence for increased qualitative susceptibility. An
increased number of stillborn pups, decreased viability and lactation
indices, decreased pre-weaning body weight and/or body-weight gain, and
changes in hematological parameters occurred at the same dose level as
maternal decrements in food intake, body weight, body-weight gain, and
changes in hematological parameters and organ weights indicative of
anemia.
    There is no evidence of neurotoxicity or immunotoxicity in the
saflufenacil database.
    Saflufenacil was weakly clastogenic in the in vitro chromosomal
aberration assay in V79 cells in the presence of S9 activation;
however, the response was not evident in the absence of S9 activation.
It was neither mutagenic in bacterial cells nor clastogenic in rodents
in vivo. Carcinogenicity studies in rats and mice showed no evidence of
increased incidence of tumors at the tested doses. Saflufenacil is
classified as ``not likely carcinogenic to humans.''
    Specific information on the studies received and the nature of the
adverse effects caused by saflufenacil 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 ``Saflufenacil. Human-Health Risk
Assessment in Support of Tolerances for Residues in/on Fish, Crayfish,
and Imported Sugarcane'' at p. 26 in docket ID numbers EPA-HQ-OPP-2012-
0775 and EPA-HQ-OPP-2013-0008.

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 saflufenacil used for
human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to saflufenacil, EPA considered exposure under the petitioned-
for tolerances as well as all existing saflufenacil tolerances in 40
CFR 180.649. EPA assessed dietary exposures from saflufenacil in food
as follows:
    i. Acute and chronic 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. Such
effects were identified for saflufenacil.
    In estimating both acute and chronic dietary exposure, EPA used the
Dietary Exposure Evaluation Model--Food Consumption Intake Database
(DEEM) which incorporates food consumption information from the United
States Department of Agriculture (USDA) National Health and Nutrition
Examination Survey, What We Eat in America, (NHANES/WWEIA; 2003-2008).
As to residue levels in food, EPA assumed 100 percent crop treated
(PCT), DEEM 7.81 default processing factors, and tolerance-level or
higher (i.e., tolerance levels adjusted to take into account metabolite
levels) residues for all foods.
    ii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that saflufenacil does not pose a cancer risk to humans.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
    iii. Anticipated residue and PCT information. EPA did not use
anticipated residue and/or PCT information in the dietary assessment
for saflufenacil. Tolerance level residues and/or 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 saflufenacil in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of saflufenacil. 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 Tier 1 Rice Model and Tier II Pesticide Root Zone
Model Ground Water (PRZM GW), the estimated drinking water
concentrations (EDWCs) of saflufenacil for acute exposures are
estimated to be 133 parts per billion (ppb) for surface water and 69.2
ppb for ground water. Chronic exposures for non-cancer assessments are
estimated to be 120 ppb for surface water and 51.5 ppb for ground
water.
    Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute dietary risk
assessment, the water concentration value of 133 ppb was used to assess
the contribution to drinking water. For chronic dietary risk
assessment, the water concentration of value 120 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). Saflufenacil is not
registered for any specific use patterns 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.'' EPA has not found
saflufenacil to share a common mechanism of toxicity with any other
substances, and saflufenacil does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that saflufenacil 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 Food Quality
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA
either retains the default value of 10X, or uses a different additional
SF when reliable data available to EPA support the choice of a
different factor.
    2. Prenatal and postnatal sensitivity. Increased fetal
susceptibility was observed in the developmental toxicity studies in
the rat and rabbit and in the 2-generation reproduction study in the
rat. Developmental effects (decreased fetal body weights and increased
skeletal variations in rats and increased liver porphyrins in rabbits)
occurred at doses that were not maternally toxic in the developmental
studies, indicating increased quantitative susceptibility. In the 2-
generation reproductive toxicity study in rats, the reported offspring
effects were more severe than the maternal effects at the same dose
level, indicating evidence for increased qualitative susceptibility. An
increased number of stillborn pups, decreased viability and lactation
indices, decreased pre-weaning body weight and/or body-weight gain, and
changes

in hematological parameters occurred at the same dose level as maternal
decrements in food intake, body weight, body-weight gain, and changes
in hematological parameters and organ weights indicative of anemia.
    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 saflufenacil is complete.
    ii. There is no indication that saflufenacil is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
    iii. The concern for increased susceptibility following prenatal or
postnatal exposure is low because clear NOAELs/LOAELs were established
for the developmental effects seen in rats and rabbits as well as for
the offspring effects seen in the 2-generation reproductive toxicity
study. Further, the dose-response relationship for the effects of
concern is also well characterized and being used for assessing risks.
None of the effects in the developmental or reproduction studies were
attributable to a single exposure and, therefore, are not of concern
for acute risk assessment. The chronic point of departure used for risk
assessment is protective of any developmental and offspring effects
observed in these studies.
    iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100 PCT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to saflufenacil in drinking water. These assessments
will not underestimate the exposure and risks posed by saflufenacil.

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. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to saflufenacil will occupy <1% of the aPAD for infants less than 1-
year old, the population group receiving the greatest exposure.
    2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
saflufenacil from food and water will utilize 18% of the cPAD for
infants <1-year old, the population group receiving the greatest
exposure. There are no residential uses for saflufenacil.
    3. Short and intermediate-term risk. Short and intermediate-term
aggregate exposure takes into account short and intermediate-term
residential exposures plus chronic exposure to food and water
(considered to be a background exposure level). Because there is no
short or intermediate-term residential exposure and chronic dietary
exposure has already been assessed under the appropriately protective
cPAD (which is at least as protective as the POD used to assess short-
term risk), no further assessment of short or intermediate-term risk is
necessary, and EPA relies on the chronic dietary risk assessment for
evaluating short-term risk for saflufenacil.
    4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, saflufenacil is not expected to pose a cancer risk to humans.
    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 saflufenacil residues.

    Adequate enforcement methods ``D0603/02'' and ``L0073/01'' (liquid
chromatography/mass spectroscopy/mass spectroscopy (LC-MS/MS)) are
available to enforce the tolerance expression. These methods may be
requested from: Chief, Analytical Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone
number:<PHONE_NUMBER>; email address<EMAIL_ADDRESS>
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. The Codex has not
established a MRL for saflufenacil.

C. Revisions to Petitioned-for Tolerances

    EPA has increased the tolerance level requested by BASF Corporation
in petition 2E8065 for sugarcane, cane from 0.03 ppm to 0.05 ppm based
on the residue data for sugarcane and use of the Organization for
Economic Co-operation and Development (OECD) tolerance calculation
procedures. Also, based on the residue data for sugarcane and to
account for concentrations of residues during processing, a tolerance
of 0.08 ppm is required for residues in or on sugarcane, molasses.
Residues did not concentrate in refined sugar, so the tolerance
proposed for this commodity will not be established at this time. In
addition, the proposed tolerances for rice straw in PP 2F8129 will not
be established since rice straw is not a significant livestock item.
Therefore, the associated request for a change in the commodity
definition is not necessary.

V. Conclusion

    Therefore, tolerances are established for residues of saflufenacil,
2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-
pyrimidinyl]-4-fluoro-N-[[methyl(1-
methylethyl)amino]sulfonyl]benzamide, and its metabolites and
degradates in or on sugarcane, cane at 0.05 ppm and sugarcane, molasses
at 0.08 ppm. Also, tolerances are established for residues of the
parent, saflufenacil, in fish-freshwater finfish and fish-shellfish,
crustacean at 0.01 ppm. Compliance with the sugarcane, cane and
sugarcane, molasses tolerances is to be determined by measuring the sum
of saflufenacil, 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-
(trifluoromethyl)- 1(2H)-pyrimidinyl]-4-fluoro-N -[[methyl(1-
methylethyl)amino]sulfonyl]benzamide, and its metabolites N-[2-chloro-
5-(2,6-dioxo-4-(trifluoromethyl)-3,6-dihydro-

1(2H)-pyrimidinyl)-4-fluorobenzoyl]-N-isopropylsulfamide and N-[4-
chloro-2-fluoro-5
({[(isopropylamino)sulfonyl]amino{time} carbonyl)phenyl]urea calculated
as the stoichiometric equivalent of saflufenacil; compliance with the
fish-freshwater finfish and fish-shellfish, crustacean tolerances are
to be determined by measuring only saflufenacil, 2-chloro-5-[3,6-
dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-4-
fluoro-N-[[methyl(1-methylethyl)amino]sulfonyl]benzamide.

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 tolerances 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).
