II. Summary of Petitioned-for Tolerance

    In the Federal Register of December 19, 2012 (77 FR 75082) (FRL-
9372-6), 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 
2F8076) by Chemtura Corporation, 199 Benson Rd., Middlebury, CT 06749. 
The petition requested that 40 CFR 180.646 be amended by establishing 
tolerances for residues of the fungicide ipconazole (2-[(4-
chlorophenyl)methyl]-5-(1-methylethyl)-1-(1H-1,2,4-triazol-1-
ylmethyl)cyclopentanol) in or on legume vegetables, succulent or dried, 
crop group 6 at 0.01 parts per million (ppm). That document referenced 
a summary of the petition prepared by Chemtura 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.

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 ipconazole including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with ipconazole 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. Ipconazole has low acute toxicity via the oral, dermal, and 
inhalation routes of exposure. It causes low to mild irritation to the 
eyes and skin; it is not a dermal sensitizer. Ipconazole may cause 
local, portal-of-entry irritation via all routes following repeated 
exposure. Systemic effects that were noted in dogs, mice, rabbits and/
or rats following exposure to ipconazole were generally limited to 
decreased body weight, body weight gain, and food consumption; and 
liver and kidney effects. Developmental effects were observed only at 
the maternally-toxic dose. No consistent evidence of neurotoxicity was 
observed following acute, subchronic, or chronic dosing in multiple 
species in the available ipconazole database and the triazole 
fungicides as a group typically show either no evidence of 
neurotoxicity or neurotoxicity at doses significantly higher than the 
regulatory points of departure. Ipconazole is classified as not likely 
to be a human carcinogen and there is no concern for mutagenicity. 
Specific information on the studies received and the nature of the 
adverse effects caused by ipconazole 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 ``Revised Ipconazole Human Health Risk 
Assessment of the Proposed Use on

[[Page 15237]]

Legume Vegetables (Crop Group 6)'' on page 23 in docket ID number EPA-
HQ-OPP-2012-0796.

B. Toxicological Points of Departure (POD)/Levels of Concern (LOC)

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological POD and LOC 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 (SF) 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 ipconazole used for 
human risk assessment is shown in the following Table of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to ipconazole, EPA considered exposure under the petitioned-
for tolerances as well as all existing ipconazole tolerances in 40 CFR 
180.646. EPA assessed dietary exposures from ipconazole 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 acute endpoint attributable to a single exposure and relevant 
for the general population was identified in the toxicity database for 
ipconazole. A developmental endpoint suitable for acute assessment was 
identified; therefore an acute dietary assessment was performed only 
for women of child-bearing age (females 13-49 years old). In estimating 
acute dietary exposure, EPA used the Dietary Exposure Evaluation Model 
software with the Food Commodity Intake Database, Version 3.16 (DEEM-
FCID), which uses food consumption information from the U.S. Department 
of Agriculture (USDA) 2003-2008 National Health and Nutrition 
Examination Surveys of What We Eat in America (NHANES/WWEIA). As to 
residue levels in food, EPA assumed tolerance level residues and 100% 
crop treated.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 2003-2008 
National Health and Nutrition Examination Surveys of What We Eat in 
America (NHANES/WWEIA). As to residue levels in food, EPA used 
tolerance level residues and assumed 100% crop treated.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that ipconazole is not a likely carcinogen. 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 ipconazole. Tolerance level residues and/or 100% 
crop treated 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 ipconazole in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/

[[Page 15238]]

transport characteristics of ipconazole. 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), and Pesticide Root Zone Model Ground Water (PRZM 
GW) models, the estimated drinking water concentrations (EDWCs) of 
ipconazole for acute exposures are estimated to be 0.173 parts per 
billion (ppb) for surface water and 1.01 ppb for ground water.
    The EDWCs of ipconazole for chronic exposures for non-cancer 
assessments are estimated to be 0.105 ppb for surface water and 0.822 
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 1.01 ppb was used to 
assess the contribution from drinking water. For chronic dietary risk 
assessment, the water concentration of value 0.822 ppb was used to 
assess the contribution from 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). Ipconazole 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.''
    Ipconazole is a member of the conazole class of pesticides. 
Although conazoles act similarly in plants by inhibiting ergosterol 
biosynthesis, there is not necessarily a relationship between their 
pesticidal activity and their mechanism of toxicity in mammals. 
Structural similarities do not constitute a common mechanism of 
toxicity. Evidence is needed to establish that the chemicals operate by 
the same, or essentially the same, sequence of major biochemical events 
(EPA, 2002). In conazoles, however, a variable pattern of toxicological 
responses is found; some are hepatotoxic and hepatocarcinogenic in 
mice. Some induce thyroid tumors in rats. Some induce developmental, 
reproductive, and neurological effects in rodents. Furthermore, the 
conazoles produce a diverse range of biochemical events, including 
altered cholesterol levels, stress responses, and altered DNA 
methylation. It is not clearly understood whether these biochemical 
events are directly connected to their toxicological outcomes. Thus, 
there is currently no conclusive data to indicate that conazoles share 
common mechanisms of toxicity and EPA is not following a cumulative 
risk approach based on a common mechanism of toxicity for the 
conazoles. For information regarding EPA's procedures for cumulating 
effects from substances found to have a common mechanism of toxicity, 
see EPA's Web site at http://www.epa.gov/pesticides/cumulative.
    Ipconazole is a triazole-derived pesticide. This class of compounds 
can form the common metabolite 1,2,4-triazole and three triazole 
conjugates (triazolylalanine, triazolylacetic acid, and 
triazolylpyrivic acid). To support existing tolerances and to establish 
new tolerances for triazole-derivative pesticides, including 
ipconazole, U.S. EPA conducted a human health risk assessment for 
exposure to 1,2,4-triazole, triazolylalanine, and triazolylacetic acid 
resulting from the use of all current and pending uses of any triazole-
derived fungicide. The risk assessment is a highly conservative, 
screening-level evaluation in terms of hazards associated with common 
metabolites (e.g., use of a maximum combination of uncertainty factors) 
and potential dietary and non-dietary exposures (i.e., high end 
estimates of both dietary and non-dietary exposures). In addition, the 
Agency retained the additional 10x FQPA SF for the protection of 
infants and children. The assessment includes evaluations of risks for 
various subgroups, including those comprised of infants and children. 
The Agency's complete risk assessment is found in the propiconazole 
reregistration docket at http://www.regulations.gov, Docket 
Identification (ID) Number EPA-HQ-OPP-2005-0497.
    An updated dietary exposure and risk analysis for the common 
triazole metabolites 1,2,4-triazole (T), triazolylalanine (TA), 
triazolylacetic acid (TAA), and triazolylpyruvic acid (TP) was 
conducted completed in May 2013, in association with a registration 
request for several other triazole fungicides. That analysis concluded 
that risk estimates were below the Agency's level of concern for all 
population groups. After inclusion of ipconazole uses covered by this 
action, aggregate risk estimates for T, TA, TAA, and TP for all 
durations of exposure and for all population subgroups are below the 
Agency's level of concern. This updated assessment may be found on 
http://www.regulations.gov by searching for the following title and 
docket number: ``Common Triazole Metabolites: Updated Aggregate Human 
Health Risk Assessment to Address The New Section 3 Registrations For 
Use of Prothioconazole on Bushberry Crop Subgroup 13-07B, Low Growing 
Berry, Except Strawberry, Crop Subgroup 13-07H, and Cucurbit Vegetables 
Crop Group 9; Use of Flutriafol on Coffee; and Ipconazole on Crop Group 
6'' (located in docket ID number EPA-HQ-OPP-2012-0876).

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 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. Offspring effects only 
occurred in the presence of maternal toxicity and were not considered 
more severe than the parental effects. Therefore, EPA concluded that 
there is no quantitative or qualitative evidence of increased 
susceptibility to rat or rabbit fetuses exposed in utero and/or post-
natally to ipconazole.
    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 ipconazole is complete. The Agency 
waived the requirement for an Immunotoxicity study for ipconazole as 
there is minimal evidence that ipconazole targets the immune system, 
nor are the conazoles of a chemical class expected to have an adverse 
effect on the immune system. An increase in leukocytes was observed in 
females at 78.3 mg/kg/day in the 28-day inhalation study, however this 
was not of concern because it was the only evidence of potential 
immunotoxicity in

[[Page 15239]]

the entire ipconazole database, the effect occurred at a dose 10-fold 
higher than the dose (7.8 mg/kg/day) that caused portal-of-entry 
effects in the same study, and the effect occurred at a dose much 
greater than the PODs chosen for risk assessment. The overall weight of 
evidence suggests that ipconazole does not target the immune system.
    ii. There is no consistent evidence of neurotoxicity in the 
available databases. Clinical signs suggestive of neurotoxicity were 
observed in the in vivo mammalian cytogenetics study; however, they 
were seen at relatively high doses, which far exceed the anticipated 
dietary exposure, and no other signs were observed in any of the other 
studies, including studies with neurotoxicity assessments. Based on the 
lack of evidence in the database, EPA waived the requirement for the 
acute neurotoxicity study. Also, the subchronic neurotoxicity study 
requirement is considered to be satisfied by the neurotoxicity 
assessments performed in both the rat subchronic and chronic toxicity/
carcinogenicity studies in which no signs of neurotoxicity were 
observed. This is consistent with what is known about the triazole 
fungicides as a class, which typically show either no evidence of 
neurotoxicity or neurotoxicity at doses significantly higher than the 
regulatory points of departure. Therefore, ipconazole is not considered 
to be neurotoxic and there is no need for a developmental neurotoxicity 
study or additional UFs to account for neurotoxicity.
    iii. There is no evidence that ipconazole results in increased 
susceptibility following in utero exposure for rats or rabbits in the 
prenatal developmental studies or in young rats in the 2-generation 
reproduction study, and there are no residual uncertainties with 
respect to pre- or postnatal exposure.
    iv. There are no residual uncertainties identified in the exposure 
databases. EPA made conservative (protective) assumptions in the ground 
and surface water modeling used to assess exposure to ipconazole in 
drinking water. These assessments will not underestimate the exposure 
and risks posed by ipconazole.

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 exposure estimates from acute dietary consumption of food and 
drinking water. Using the exposure assumptions discussed in this unit 
for acute exposure, the acute dietary exposure from food and water to 
ipconazole will occupy <1% of the aPAD for females 13-49 years 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 
ipconazole from food and water will utilize <1% of the cPAD for 
children 1-2 years old the population group receiving the greatest 
exposure. There are no residential uses for ipconazole.
    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).
    A short-term adverse effect was identified; however, ipconazole is 
not registered for any use patterns that would result in short-term 
residential exposure. Because there is no short-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-term risk is necessary, and EPA relies on the chronic dietary 
risk assessment for evaluating short-term risk for ipconazole.
    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, 
ipconazole is not registered for any use patterns that would result in 
intermediate-term residential 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 ipconazole.
    5. Aggregate cancer risk for U.S. population. Ipconazole has been 
classified as not likely to be carcinogenic, and 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 ipconazole residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (liquid chromatography/mass 
spectrometry/mass spectrometry (LC/MS/MS) (AC/3020)) is available to 
enforce the tolerance expression. The method may be requested from: 
Chief, Analytical Chemistry Branch, Environmental Science Center, 701 
Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; 
email address: residuemethods@epa.gov.

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 ipconazole on vegetable, 
legume, group 6.

C. Revisions to Petitioned-for Tolerances

    The petitioner requested a tolerance for residues of ipconazole in 
or on ``legume vegetables succulent or dried, crop group 6''. EPA is 
correcting the commodity term and establishing a tolerance for 
``vegetable, legume, group 6''.

V. Conclusion

    Therefore, tolerances are established for residues of ipconazole 
(2-[(4-chlorophenyl)methyl]-5-(1-

[[Page 15240]]

methylethyl)-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol) in or on 
vegetable, legume, group 6 at 0.01 ppm. EPA is revising the tolerance 
expression for ipconazole to clarify that metabolites and degradates 
are covered by the tolerances and to specify how compliance with the 
tolerances is to be measured. The existing tolerances for pea and bean, 
dried shelled, except soybean, subgroup 6C at 0.01 ppm and soybean, 
seed at 0.01 ppm will be removed from paragraph (a) of Sec.  180.646 as 
these tolerances are encompassed within vegetable, legume, group 6.

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).
