II. Summary of Petitioned-For Tolerance

    In the Federal Register of February 11, 2020 (85 FR 7708) (FRL-
10005-02), 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 
8F8710) by SePRO Corporation, 11550 North Meridian Street, Suite 600, 
Carmel, IN 46032. The petition requested that 40 CFR part 180 be 
amended by establishing tolerances for residues of the herbicide 
fluridone in or on avocados, mandarins, pomegranates, pistachios, and 
the stone fruit group (crop group 12) at 0.1 parts per million (ppm). 
That document referenced a summary of the petition prepared by SePRO 
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 petition, EPA is 
establishing the requested tolerances with slight variations to reflect 
the correct commodity definitions.

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 fluridone including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with fluridone 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 liver and kidneys were identified as the primary target organs 
based on a multitude of organ specific effects noted across the 
toxicity database. All model species exhibited indications of liver 
toxicity that were often accompanied by body weight effects. No signs 
of neurotoxicity were identified in the rest of the toxicity database. 
Toxicity from repeated dose dermal exposures was limited to irritation 
effects on the skin (erythema, desquamation, epidermal fissures). No 
evidence of immunotoxicity, mutagenicity, or carcinogenicity were noted 
in the toxicity database. Fluridone did not demonstrate mutagenic 
behavior either in vitro or in vivo nor did exposure result in an 
increased incidence of tumors. The EPA concluded that fluridone should 
be classified as ``not likely'' to be a human carcinogen.
    Specific information on the studies received and the nature of the 
adverse effects caused by fluridone 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 Fluridone. Human Health Risk Assessment 
for the Section 3 Registration on: Avocado, Mandarin (Tangerine), 
Pistachio, Pomegranate, and Stone Fruit (Crop Group 12-12) in docket ID 
number EPA-HQ-OPP-2019-0074.

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 fluridone used for 
human risk assessment is discussed in Unit III.B. of the final rule 
published in the Federal Register of February 17, 2016 (81 FR 7982) 
(FRL-9941-69).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to fluridone, EPA considered exposure under the petitioned-for 
tolerances as well as all existing fluridone tolerances in 40 CFR 180. 
EPA assessed dietary exposures from fluridone 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

[[Page 29635]]

exposure. Such effects were identified for fluridone. In estimating 
acute dietary exposure, EPA used food consumption information from the 
United States Department of Agriculture (USDA) National Health and 
Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). 
This dietary survey was conducted from 2003 to 2008. 100 percent crop 
treated (PCT), tolerance-level residues, and default processing factors 
were assumed for this assessment.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA NHANES/
WWEIA. This dietary survey was conducted from 2003 to 2008. 100 PCT, 
tolerance-level residues, and default processing factors were assumed.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that fluridone 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 percent crop treated (PCT) information. 
EPA did not use anticipated residue and/or PCT information in the 
dietary assessment for fluridone. Tolerance-level residues and/or 100% 
CT 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 fluridone in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of fluridone. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the Tier 1 Rice Model v2.0, the estimated drinking water 
concentrations (EDWCs) of fluridone for acute exposures are estimated 
to be 150 parts per billion (ppb) for surface water and 45 ppb for 
ground water. For chronic exposures for non-cancer assessments are 
estimated to be 107 ppb for surface water and 43 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 150 ppb was used to assess 
the contribution to drinking water. For chronic dietary risk 
assessment, the water concentration of value 107 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).
    Fluridone is currently registered for the following uses that could 
result in residential exposures: From use on ponds (including a 
homeowner use), lakes, reservoirs, and rivers. EPA assessed residential 
exposure using the following assumptions: Adult applicators may be 
exposed (dermal and inhalation) while applying the pesticide to 
residential ponds. Residential handler exposure is expected to be 
short-term in duration only. Intermediate-term and chronic exposures 
are not likely because of the intermittent nature of applications by 
homeowners. There is also potential for residential post-application 
exposure (dermal, inhalation and incidental ingestion) for adults and 
children (3 to <6 years old) swimming in treated water. Residential 
post-application exposure is expected to be short-term in duration 
only. Further information regarding EPA standard assumptions and 
generic inputs for residential exposures may be found at 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 fluridone 
to share a common mechanism of toxicity with any other substances, and 
fluridone does not appear to produce a toxic metabolite produced by 
other substances. For the purposes of this tolerance action, therefore, 
EPA has assumed that fluridone 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 website 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 was no evidence of 
qualitative susceptibility in fetuses in the rat and rabbit 
developmental study. Equivocal susceptibility was observed in the young 
from the F2 population in the reproductive study during the lactation 
phase (based decreased body weight); however, body weight of the F2 
offspring returned to control levels after the lactation period and no 
evidence of susceptibility was observed in the F3 offspring.
    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. More information on that decision can be 
found at http://www.regulations.gov in document Fluridone. Human Health 
Risk Assessment for the Section 3 Registration on: Avocado, Mandarin 
(Tangerine), Pistachio, Pomegranate, and Stone Fruit (Crop Group 12-12) 
in docket ID number EPA-HQ-OPP-2019-0074.

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 fluridone will occupy 2.3% of the aPAD for all infants (<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

[[Page 29636]]

that chronic exposure to fluridone from food and water will utilize 7% 
of the cPAD for children aged 1 to 2 the population group receiving the 
greatest exposure. Based on the explanation in Unit III.C.3., regarding 
residential use patterns, chronic residential exposure to residues of 
fluridone is not expected.
    3. Short-term risk. Short-term aggregate exposure takes into 
account short-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level). Fluridone is 
currently registered for uses that could result in short-term 
residential exposure, and the Agency has determined that it is 
appropriate to aggregate chronic exposure through food and water with 
short-term residential exposures to fluridone. Using the exposure 
assumptions described in this unit for short-term exposures, EPA has 
concluded the combined short-term food, water, and residential 
exposures result in aggregate MOEs of 1,300 for adults and 1,600 for 
children. Because EPA's level of concern for fluridone is a MOE of 100 
or below, these MOEs are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level). An intermediate-term adverse effect was identified; however, 
fluridone is not registered for any use patterns that would result in 
intermediate-term residential exposure. Intermediate-term risk is 
assessed based on intermediate-term residential exposure plus chronic 
dietary exposure. Because there is no 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 intermediate-term risk), no further assessment 
of intermediate-term risk is necessary, and EPA relies on the chronic 
dietary risk assessment for evaluating intermediate-term risk for 
fluridone.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, fluridone is not expected to pose a cancer risk to humans.
    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 fluridone residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (high performance liquid 
chromatography (HPLC) method (originally submitted as method AM-AA-CA-
RO52-AA-755)) is available to enforce the tolerance expression.

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 fluridone.

V. Conclusion

    Therefore, tolerances are established for residues of fluridone, in 
or on avocado, tangerine, pomegranate, pistachio, and the fruit, stone, 
group 12-12 at 0.1 ppm.

VI. Statutory and Executive Order Reviews

    This action 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 action has been 
exempted from review under Executive Order 12866, this action 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), nor is it considered a 
regulatory action under Executive Order 13771, entitled ``Reducing 
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3, 
2017). This action 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 action 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 action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(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 (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

[[Page 29637]]

Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
