II. Background and Statutory Findings

    EPA, on its own initiative, in accordance with FFDCA sections 
408(e) and 408(l)(6) of, 21 U.S.C. 346a(e) and 346a(1)(6), is 
establishing time-limited tolerances for the fungicide, isofetamid, N-
[1,1-dimethyl-2-[2-methyl-4-(1-methylethoxy)phenyl]-2-oxoethyl]-3-
methyl-2-thiophenecarboxamide, in or on caneberry subgroup 13-07A at 
4.0 parts per million (ppm) and bushberry subgroup 13-07B at 5.0 ppm. 
These time-limited tolerances expire 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

[[Page 70971]]

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 . . . .''
    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 Isofetamid on Caneberry Subgroup 13-07A 
and Bushberry Subgroup 13-07B and FFDCA Tolerances

    The Washington State Department of Agriculture (WSDA) requested an 
emergency exemption for the use of isofetamid on blackberries, 
blueberries, and raspberries to control gray mold caused by Botrytis 
cinerea. Botrytis cinerea has a very wide host range which causes gray 
mold that becomes visible on developed fruit just prior to harvest. 
According to WSDA, Botrytis cinerea developed fungicide resistance and 
coupled with the unseasonably warm weather in Washington State, created 
conditions favorable for gray mold outbreaks resulting in crop damage 
and yield loss. After having reviewed the submission, EPA determined 
that an emergency condition exists for Washington, and that the 
criteria for approval of an emergency exemption are met. EPA has 
authorized a specific exemption under FIFRA section 18 for the use of 
isofetamid on blueberry, blackberry, and raspberry for control of gray 
mold (Botrytis cinerea) in Washington.
    As part of its evaluation of the emergency exemption application, 
EPA assessed the potential risks presented by residues of isofetamid in 
or on caneberry subgroup 13-07A and bushberry subgroup 13-07B. 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 exemption 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 these time-limited tolerances expire on 
December 31, 2019, under FFDCA section 408(l)(5), residues of the 
pesticide not in excess of the amounts specified in the tolerance 
remaining in or on caneberry subgroup 13-07A and bushberry subgroup 13-
07B 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 these time-limited tolerances 
at the time of that application. EPA will take action to revoke these 
time-limited tolerances earlier if any experience with, scientific data 
on, or other relevant information on this pesticide indicate that the 
residues are not safe.
    Because these time-limited tolerances are being approved under 
emergency conditions, EPA has not made any decisions about whether 
isofetamid meets FIFRA's registration requirements for use on caneberry 
subgroup 13-07A and bushberry subgroup 13-07B 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 isofetamid 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 Washington to use this pesticide on the applicable crops 
under FIFRA section 18 absent the issuance of an emergency exemption 
applicable within that State. For additional information regarding the 
emergency exemption for isofetamid, 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 this emergency exemption request and 
the time-limited tolerances for isofetamid, N-[1,1-dimethyl-2-[2-
methyl-4-(1-methylethoxy)phenyl]-2-oxoethyl]-3-methyl-2-
thiophenecarboxamide, on caneberry subgroup 13-07A at 4.0 ppm and 
bushberry subgroup 13-07B at 5.0 ppm. EPA's assessment of exposures and 
risks associated with establishing time-limited tolerances 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://www2.epa.gov/
pesticide-science-and-

[[Page 70972]]

assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for isofetamid used for 
human risk assessment is discussed in Unit III.B of the final rule 
published in the Federal Register of July 30, 2015 (80 FR 45438) (FRL-
9923-86).

B. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to isofetamid, EPA considered exposure under the time-limited 
tolerances established by this action as well as all existing 
isofetamid tolerances in 40 CFR 180.681. EPA assessed dietary exposures 
from isofetamid in food as follows:
    i. Acute exposure. No acute effects were identified in the 
toxicological studies for isofetamid; therefore, a quantitative acute 
dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the DEEM-FCID, Version 3.16 software with 2003-2008 
food consumption data from the USDA's National Health and Nutrition 
Examination Survey, What We Eat in America (NHANES/WWEIA). As to 
residue levels in food, EPA evaluated the combined residues of parent 
isofetamid and its metabolite GPTC (N-[l,l-dimethyl-2-(4-[beta]-D-
glucopyranosyloxy-2-methylphenyl)-2-oxoethyl]-3-methyl-2-
thiophenecarboxamide). EPA's chronic dietary exposure assessment is 
based on mean residue levels found in field trials for each of the 
crops on which isofetamid is used, using empirical and default 
processing factors as available, and assuming 100 percent crop treated 
(PCT).
    iii. Cancer. Based on the data summarized in Unit IV.A., EPA has 
concluded that isofetamid 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 crop-specific PCT information in the dietary assessment 
for isofetamid. EPA assumed that for each food commodity on which 
isofetamid is used, 100% of the commodity has combined residues of 
parent isofetamid and GPTC equal to the mean field trial residues.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for isofetamid in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of isofetamid. 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 Pesticide Flooded Application Model (PFAM) and the 
Pesticide Root Zone Model Ground Water (PRZM GW), the estimated 
drinking water concentrations (EDWCs) of isofetamid for chronic 
exposures for non-cancer assessments are estimated to be 110 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 chronic dietary risk 
assessment, the water concentration of value 110 parts per billion 
(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).
    Isofetamid is currently registered for the following uses that 
could result in residential exposures: Turfgrass including golf 
courses, residential lawns, and recreational turfgrass. Since there may 
be residential use sites, residential handler exposure and risk 
estimates were calculated for all possible residential exposure 
scenarios. Given that there is no dermal toxicity concern in regard to 
isofetamid, the residential handler assessment only includes the 
inhalation route of exposure. Residential handler exposure is expected 
to be short-term in duration as a maximum of eight applications are 
allowed per year. Thus, intermediate-term exposures are not likely 
because of the intermittent nature of applications by homeowners. Unit 
exposure values and estimates for area treated or amount handled were 
taken from the Agency's 2012 Standard Operating Procedures for 
Residential Pesticide Exposure Assessment (Section 3: Lawns/Turf). The 
algorithms used to estimate exposure and dose for residential handlers 
can be found in the 2012 Residential SOPs (Section 3: Lawns/Turf). For 
all residential exposure scenarios, isofetamid risk estimates are not 
of concern. Short-term inhalation MOEs range from 850,000 to 
18,000,000.
    Further information regarding EPA standard assumptions and generic 
inputs for residential exposures may be found at: http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide.
    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 isofetamid to share a common mechanism of 
toxicity with any other substances, and isofetamid does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
isofetamid 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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

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 
Safety Factor (SF) when reliable data available to EPA support the 
choice of a different factor.
    2. Prenatal and postnatal sensitivity. There is no evidence of 
developmental toxicity or reproductive susceptibility associated with 
isofetamid, and there are no residual uncertainties concerning pre- or 
post-natal toxicity or exposure.
    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 for isofetamid. That decision is based on 
the following findings:
    i. The toxicity database for isofetamid is complete.
    ii. There is no indication that isofetamid is a neurotoxic chemical 
and

[[Page 70973]]

there is no need for a developmental neurotoxicity study or additional 
Uncertainty Factors (UF) to account for neurotoxicity.
    iii. There is no evidence that isofetamid results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and average (mean) level field trial residues. EPA made 
conservative (protective) assumptions in the ground and surface water 
modeling used to assess exposure to isofetamid in drinking water. EPA 
used similarly conservative assumptions to assess postapplication 
exposure of children as well as incidental oral exposure of toddlers. 
These assessments will not underestimate the exposure and risks posed 
by isofetamid.

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 and no acute dietary endpoint was selected. Therefore, 
isofetamid is not expected to pose an acute dietary risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
isofetamid from food and water will utilize <1% of the cPAD for 
children 1-2 years old, the population group receiving the greatest 
exposure. Based on the explanation in the unit regarding residential 
use patterns, chronic residential exposure to residues of isofetamid 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). Isofetamid 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 isofetamid.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential isofetamid exposures result in aggregate MOEs of 24,000 
and 3,900 for adults and children (1-2 years old), respectively. 
Because EPA's level of concern for isofetamid 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 non-dietary, non-occupational 
exposure plus chronic exposure to food and water (considered to be a 
background exposure level). An intermediate-term adverse effect was 
identified; however, isofetamid 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 isofetamid.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, isofetamid 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 isofetamid residues.

V. Other Considerations

A. Analytical Enforcement Methodology

    An adequate enforcement methodology (liquid chromatography with 
tandem mass spectrometry (LC-MS/MS)) 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: 
[email protected].

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 any MRLs for isofetamid.

VI. Conclusion

    Therefore, time-limited tolerances are established for residues of 
isofetamid, isofetamid, in or on caneberry subgroup 13-07A and 
bushberry subgroup 13-07B at 4.0 and 5.0 ppm. These tolerances expire 
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

[[Page 70974]]

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).
