II. Background and Statutory Findings

    EPA, on its own initiative, in accordance with FFDCA sections 
408(e) and 408(l)(6), 21 U.S.C. 346a(e) and 346a(1)(6), is establishing 
a time-limited tolerance for residues of hexythiazox and its 
metabolites containing the (4-chlorophenyl)-4-methyl-2-oxo-3-
thiazolidine moiety, calculated as the stoichiometric equivalent of 
hexythiazox, in or on sugar beet root at 0.15 parts per million (ppm). 
This time-limited tolerance expires on December 31, 2019.
    Section 408(l)(6) of FFDCA requires EPA to establish a time-limited 
tolerance or exemption from the requirement for a tolerance for 
pesticide chemical residues in food that will result from the use of a 
pesticide under an emergency exemption granted by EPA under FIFRA 
section 18. Such tolerances can be established without providing notice 
or period for public comment. EPA does not intend for its actions on 
FIFRA section 18 related time-limited tolerances to set binding 
precedents for the application of FFDCA section 408 and the safety 
standard to other tolerances and exemptions. Section 408(e) of FFDCA 
allows EPA to establish a tolerance or an exemption from the 
requirement of a tolerance on its own initiative, i.e., without having 
received any petition from an outside party.
    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

[[Page 73215]]

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. . . .''
    Section 18 of FIFRA authorizes EPA to exempt any Federal or State 
agency from any provision of FIFRA, if EPA determines that ``emergency 
conditions exist which require such exemption.'' EPA has established 
regulations governing such emergency exemptions in 40 CFR part 166.

III. Emergency Exemption for Hexythiazox on Sugar Beet Root and FFDCA 
Tolerances

    The Idaho and Oregon State Departments of Agriculture (the States) 
reported that two-spotted spider mite infestations at above-normal 
levels have caused severe losses in the past several years in sugar 
beet fields. Based upon activity observed in the early spring of 2014, 
they projected similar mite population levels for the 2014 season as 
well. The States claimed that alternative controls and practices would 
not provide adequate control with high infestations and would not 
prevent significant economic losses from occurring. The States also 
noted concern that some of the alternative pesticides may be harmful to 
beneficial insects which help control mites, and to bees pollinating 
crops in the area. The applicants asserted that an emergency condition 
existed in accordance with the criteria for approval of an emergency 
exemption, and utilized crisis exemptions under FIFRA section 18 which 
allowed the use of hexythiazox on sugar beet root for control of two-
spotted spider mites in the Idaho and Oregon. After having reviewed the 
submissions, EPA concurred that an emergency condition existed.
    As part of its evaluation of the emergency exemption applications, 
EPA assessed the potential risks presented by residues of hexythiazox 
in or on sugar beet root. In doing so, EPA considered the safety 
standard in FFDCA section 408(b)(2), and EPA decided that the necessary 
tolerance under FFDCA section 408(l)(6) would be consistent with the 
safety standard and with FIFRA section 18. Consistent with the need to 
move quickly on the emergency exemptions in order to address an urgent 
non-routine situation and to ensure that the resulting food is safe and 
lawful, EPA is issuing this tolerance without notice and opportunity 
for public comment as provided in FFDCA section 408(l)(6). Although 
this time-limited tolerance expires on December 31, 2019, under FFDCA 
section 408(l)(5), residues of the pesticide not in excess of the 
amount specified in the tolerance remaining in or on sugar beet root 
after that date will not be unlawful, provided the pesticide was 
applied in a manner that was lawful under FIFRA, and the residues do 
not exceed a level that was authorized by this time-limited tolerance 
at the time of that application. EPA will take action to revoke this 
time-limited tolerance earlier if any experience with, scientific data 
on, or other relevant information on this pesticide indicate that the 
residues are not safe.
    Because this time-limited tolerance is being approved under 
emergency conditions, EPA has not made any decisions about whether 
hexythiazox meets FIFRA's registration requirements for use on sugar 
beets or whether permanent tolerances for this use would be 
appropriate. Under these circumstances, EPA does not believe that this 
time-limited tolerance decision serves as a basis for registration of 
hexythiazox by a State for special local needs under FIFRA section 
24(c). Nor does this tolerance by itself serve as the authority for 
persons in any State other than Idaho and Oregon to use this pesticide 
on sugar beets under FIFRA section 18 absent the issuance of an 
emergency exemption applicable within that State. For additional 
information regarding the emergency exemption for hexythiazox, contact 
the Agency's Registration Division at the address provided under FOR 
FURTHER INFORMATION CONTACT.

IV. 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 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 expected as a result of these emergency exemption requests and 
the time-limited tolerance for residues of hexythiazox in or on sugar 
beet root at 0.15 ppm. EPA's assessment of exposures and risks 
associated with establishing the time-limited tolerance follows.

A. 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 hexythiazox used for 
human risk assessment is discussed in Unit III.B. of the final rule 
published in the Federal Register of February 8, 2013 (78 FR 9322) 
(FRL-9376-9).

[[Page 73216]]

B. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to hexythiazox, EPA considered exposure under the time-limited 
tolerance established by this action as well as all existing 
hexythiazox tolerances in 40 CFR 180.448. EPA assessed dietary 
exposures from hexythiazox in food as follows:
    i. Acute exposure. No adverse acute effects were identified in the 
toxicological studies for hexythiazox; 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 2003-2008 National Health and Nutrition Examination 
Survey, What We Eat in America (NHANES/WWEIA). As to residue levels in 
food, EPA used tolerance level residues, assumed 100 percent crop 
treated (PCT) and incorporated default processing factors from EPA's 
Dietary Exposure Evaluation Model when processing data were not 
available.
    iii. Cancer. EPA determines whether quantitative cancer exposure 
and risk assessments are appropriate for a food-use pesticide based on 
the weight of the evidence from cancer studies and other relevant data. 
Cancer risk is quantified using a linear or nonlinear approach. If 
sufficient information on the carcinogenic mode of action is available, 
a threshold or nonlinear approach is used and a cancer RfD is 
calculated based on an earlier noncancer key event. If carcinogenic 
mode of action data are not available, or if the mode of action data 
determines a mutagenic mode of action, a default linear cancer slope 
factor approach is utilized.
    Based on the toxicological endpoints for hexythiazox used for human 
risk assessment discussed in Unit III.B. of the February 8, 2013 
Federal Register final rule, EPA has concluded that hexythiazox should 
be classified as ``Likely to be Carcinogenic to Humans'' and that a 
nonlinear RfD approach is appropriate for assessing cancer risk. Cancer 
risk was therefore assessed using the chronic RfD and the chronic 
exposure estimates as discussed in Unit IV.B.1.ii. of this document.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue and/or PCT information in the dietary assessment 
for hexythiazox. 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 hexythiazox in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of hexythiazox. 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 Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS), the estimated drinking water concentration (EDWC) 
of hexythiazox for chronic exposures for non-cancer and cancer 
assessments is estimated to be 4.31 parts per billion (ppb) for surface 
water. Since surface water residue values greatly exceed groundwater 
EDWCs, surface water residues were used in the dietary risk 
assessments. Modeled estimates of drinking water concentrations were 
directly entered into the dietary exposure model.
    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).
    Hexythiazox is currently registered for the following uses that 
could result in residential exposures: Ornamental plantings, turf, and 
fruit and nut trees in residential settings. EPA assessed residential 
exposure using the following assumptions: Residential handler exposures 
are expected to be short-term (1 to 30 days) via either the dermal or 
inhalation routes of exposure. Since no dermal hazards were identified 
for hexythiazox, MOEs were calculated for the inhalation route of 
exposure only. Both adults and children may be exposed to hexythiazox 
residues from contact with treated lawns or treated residential plants. 
Adult post-application exposures were not assessed for hexythiazox 
because no dermal hazards were identified, and inhalation exposures are 
typically negligible in outdoor settings. The post-application 
exposures were assessed for children from incidental oral exposure 
resulting from transfer of residues from the hands or objects to the 
mouth, and from the incidental ingestion of soil. Post-application 
hand-to-mouth and object-to-mouth exposures are expected to be short-
term (1 to 30 days) in duration due to the intermittent nature of 
applications in residential settings. Given the long half-life of 
hexythiazox in soil, intermediate-term (1 to 6 months) exposure is also 
possible from incidental ingestion of soil. Further information 
regarding EPA standard assumptions and generic inputs for residential 
exposures may be found at: http://www.epa.gov/pesticides/science/USEPA-OPP-HED_Residential%20SOPs_Oct2012.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 hexythiazox to share a common mechanism of 
toxicity with any other substances, and hexythiazox does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
hexythiazox 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.

C. 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. The prenatal and postnatal 
toxicology database indicates no increased susceptibility of rats or 
rabbits to in utero and/or postnatal exposure to hexythiazox.
    3. Conclusion. EPA has determined that reliable data show that 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:

[[Page 73217]]

    i. The toxicity database for hexythiazox is complete.
    ii. There is no indication that hexythiazox is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional uncertainty factors (UFs) to account for neurotoxicity.
    iii. There is no evidence that hexythiazox results in increased 
susceptibility of 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 PCT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to hexythiazox 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 
hexythiazox.

D. 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. Therefore, hexythiazox 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 
hexythiazox from food and water will utilize 82% of the cPAD for 
children 1 to 2 years of age, the population group receiving the 
greatest exposure. Based on the explanation in this document in the 
unit regarding residential use patterns, chronic residential exposure 
to residues of hexythiazox is not expected. Because the cPAD utilized 
for the most vulnerable population group is below 100%, aggregate 
exposure to hexythiazox is not expected to cause chronic risks of 
concern.
    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).
    Hexythiazox 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 hexythiazox.
    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 9,600 (adult 
females), 9,100 (adult males), and 1,300 for children. Because EPA's 
level of concern for hexythiazox is an MOE of 100 or below, these MOEs 
are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term non-dietary, non-occupational 
exposure plus chronic exposure to food and water (considered to be a 
background exposure level).
    Hexythiazox is currently registered for uses that could result in 
intermediate-term residential exposure, and the Agency has determined 
that it is appropriate to aggregate chronic exposure through food and 
water with intermediate-term residential exposures to hexythiazox.
    Using the exposure assumptions described in this unit for 
intermediate-term exposures, EPA has concluded that the combined 
intermediate-term food, water, and residential exposures result in 
aggregate MOEs of 9,800 (adult females), 9,300 (adult males), and 1,500 
for children. Because EPA's level of concern for hexythiazox is an MOE 
of 100 or below, these MOEs are not of concern.
    5. Aggregate cancer risk for U.S. population. EPA's classification 
of hexythiazox as ``Likely to be Carcinogenic to Humans'' is based upon 
increased benign and malignant liver tumors in high-dose female mice, 
and benign mammary tumors in high-dose male rats. EPA determined that a 
nonlinear RfD quantitative estimation of human cancer risk is 
appropriate, based on the following: The liver tumors observed are very 
common in that species of mice and were only seen in high dose female 
mice; the mammary tumors observed were benign and only occurred in the 
high-dose male rats; no mutagenic effects were observed in mammalian 
somatic and germ cell studies; and the chronic NOAEL used for 
determining the RfD is 65 times lower than the lowest dose at which 
tumors were observed. Therefore, the nonlinear chronic RfD approach is 
protective of all chronic effects including potential carcinogenicity 
of hexythiazox. As a result, the expected aggregate exposure to 
hexythiazox does not present cancer risks of concern.
    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 hexythiazox residues.

V. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (high performance liquid 
chromatography method with ultraviolet detection (HPLC/UV)) is 
available for enforcement of tolerances for residues of hexythiazox and 
its metabolites containing the PT-1-3 moiety in crop and livestock 
commodities. This method is listed in the ``EPA Index of Residue 
Analytical Methods'' under hexythiazox as Method AMR-985-87.

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 an MRL for hexythiazox in or on sugar 
beet root.

VI. Conclusion

    Therefore, a time-limited tolerance is established for residues of 
hexythiazox and its metabolites containing the (4-chlorophenyl)-4-
methyl-2-oxo-3-thiazolidine moiety, calculated as the stoichiometric 
equivalent of

[[Page 73218]]

hexythiazox, in or on beet, sugar, root at 0.15 ppm. This tolerance 
expires on December 31, 2019.

VII. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA sections 408(e) and 
408(l)(6). 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). 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 in accordance 
with FFDCA sections 408(e) and 408(l)(6), 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 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).

VIII. 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).
