This regulation establishes
tolerances for residues of isofetamid in
or on multiple commodities which are
identified and discussed later in this
document. ISK Biosciences Corporation
requested these tolerances under the
Federal Food, Drug, and Cosmetic Act
(FFDCA). The regulation also removes
the existing time-limited tolerances for
residues on ‘‘bushberry subgroup 13–
07B’’ and ‘‘caneberry subgroup 13–07A’’
because they are no longer needed as a
result of this action.
DATES: This regulation is effective June
14, 2017. Objections and requests for
hearings must be received on or before
August 14, 2017, and must be filed in
accordance with the instructions

II. Summary of Petitioned-For
Tolerance
In the Federal Register of February 7,
2017 (82 FR 9555) (FRL–9956–86), 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 6F8457) by ISK Biosciences
Corporation, 7470 Auburn Rd., Suite A,
Concord, OH 44077. The petition
requested that 40 CFR 180.681 be
amended by establishing tolerances for
residues of the fungicide isofetamid, N[1,1-dimethyl-2-[2-methyl-4-(1methylethoxy)phenyl]-2-oxoethyl]-3methyl-2-thiophenecarboxamide, in or
on caneberry subgroup 13–07A at 3.0
parts per million (ppm); apple, wet
pomace, at 2.0 ppm; bushberry,
subgroup 13–07B at 6.0 ppm; cattle, fat
at 0.01 ppm; cattle, meat byproducts at
0.01 ppm; cherry subgroup 12–12A at
5.0 ppm; fruit, pome, group 11–10 at 0.6
ppm; fruit, small vine climbing, except
grape, subgroup 13–7E at 9.0 ppm; goat,
fat at 0.01 ppm; goat, meat byproducts
at 0.01 ppm; horse, fat at 0.01 ppm;
horse, meat byproducts at 0.01 ppm; pea
and bean, dried shelled, except soybean,
subgroup 6C, except cowpea and field
pea at 0.05 ppm; pea and bean,
succulent shelled, subgroup 6B, except
cowpea at 0.04 ppm; peach subgroup
12–12B at 3.0 ppm; plum, prune, dried
at 3.5 ppm; plum subgroup 12–12C at
0.8 ppm; sheep, fat at 0.01 ppm; sheep,
meat byproducts at 0.01 ppm; and
vegetable, legume, edible podded,
subgroup 6A at 1.5 ppm. That document
referenced a summary of the petition
prepared by ISK Biosciences
Corporation, the registrant, which is
available in the docket, https://
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 has revised
some of the proposed tolerances;
determined that tolerances for residues
in livestock commodities are not
required; and corrected some of the
commodity definitions. The reason for
these changes are explained in Unit
IV.D.
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
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
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 isofetamid
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with isofetamid 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 toxicology
database is complete for isofetamid. In
repeated dose studies, the liver was the
primary target organ in the rat, mouse,
and dog, as indicated by increased liver
weights, changes in the clinical
chemistry values, and liver
hypertrophy. A second target organ was
the thyroid in the rat and dog, as
indicated by changes in thyroid weights
and histopathology. Adrenal weight
changes were observed in the
subchronic rat and dog studies. In the
rat and dog, the dose levels where
toxicity was observed were similar or
higher in the chronic studies compared
with the respective subchronic studies,
showing an absence of progression of
liver toxicity with time. There was no
evidence of carcinogenicity in the rat or
mouse cancer studies; the mutagenicity
battery was negative. There are no
genotoxicity, neurotoxicity, or
immunotoxicity concerns observed in
the available toxicity studies.
Developmental toxicity was not
observed in the rat or rabbit, and
offspring effects such as decreased body
PO 00000
Frm 00046
Fmt 4700
Sfmt 4700
weight were seen only in the presence
of parental toxicity in the multigeneration rat study. Isofetamid is
classified as ‘‘Not Likely to be
Carcinogenic to Humans’’ based on the
absence of increased tumor incidence in
acceptable/guideline carcinogenicity
studies in rats and mice. Isofetamid is
not acutely toxic; it is classified as
Toxicity Category III for acute oral and
dermal exposure, and Toxicity Category
IV for inhalation exposure. Furthermore,
it is not irritating to the eye or skin, and
it is not a dermal sensitizer.
Specific information on the studies
received and the nature of the adverse
effects caused by isofetamid as well as
the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies are can be found at

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 https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-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 45440) (FRL–9923–86).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to isofetamid, EPA considered
exposure under the petitioned-for
tolerances 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. 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 such effects were
identified in the toxicological studies
for isofetamid; therefore, a quantitative
acute dietary exposure assessment is
unnecessary.
ii. Chronic exposure. An unrefined
chronic (food and drinking water)
dietary assessment was conducted for
all registered and proposed food uses of
isofetamid using the Dietary Exposure
Evaluation Model software with the
Food Commodity Intake Database
(DEEM–FCID) Version 3.16. This
software uses 2003–2008 food
consumption data from the U.S.
Department of Agriculture’s (USDA’s)
National Health and Nutrition
Examination Survey, What We Eat in
America (NHANES/WWEIA). The
chronic dietary (food and drinking
water) exposure assessment for
isofetamid incorporated existing
tolerance-level residues, Agencyrecommended tolerance-level residues
for proposed tolerances, DEEM default
processing factors, and 100 PCT
(percent crop treated). Some tolerance
levels were adjusted to include residues
of the metabolite, GPTC (a residue of
concern for risk assessment). DEEM
default processing factors were used for
dried apples, apple juice, dried pear,
cherry juice, dried apricot, dried peach,
plum, prune juice, cranberry juice, and
grape juice. The EDWC of 110
VerDate Sep<11>2014

Jkt 241001
microgram/Liter (mg/L) was
incorporated directly into the dietary
assessment.
iii. Cancer. Based on the data
summarized in Unit III.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 anticipated residue and/or PCT
information in the dietary assessment
for isofetamid. Tolerance level residues
and/or 100 PCT were assumed for all
food commodities.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for 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
https://www2.epa.gov/pesticide-scienceand-assessing-pesticide-risks/aboutwater-exposure-models-used-pesticide.
Based on the Pesticide Flooded
Application Model 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
parts per billion (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 value of 110 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 nonoccupational, 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. It is
currently under review for registering
use on ornamental plants. The proposed
ornamental use is not intended for
homeowner use and therefore a
quantitative residential handler
assessment was not conducted.
Additionally, post-application
exposures for adults and children are
expected to be negligible. However, the
existing turf use may result in short- and
PO 00000
Frm 00047
Fmt 4700
Sfmt 4700
27151
intermediate-term exposures.
Residential exposure may occur by the
dermal and incidental oral routes of
exposures following the application of
isofetamid on residential turf. However,
since dermal hazard has not been
identified for isofetamid, the only
exposure scenario quantitatively
assessed is for post-application
incidental oral (for children 1 to <2
years old). These exposures have been
assessed with current policies, which
include the Agency’s 2012 Residential
Standard Operating Procedures (https://
www.epa.gov/pesticides/science/
residential-exposure-sop.html) along
with policy changes for body weight
assumptions.
Even though a previous risk
assessment identified residential
handler risk estimates for use in
aggregate assessment, based on current
policy and that isofetamid products are
intended for sale/use to/by professional
applicators, residential handler
exposure assessments for turf are no
longer applicable to the isofetamid
aggregate risk assessment. Therefore, the
aggregate assessment for this action only
includes a risk contribution from
residential post-application incidental
oral exposure for children 1 to <2 years
old.
There is the potential for postapplication exposure for individuals as
a result of being in an environment that
has been previously treated with
isofetamid such as residential
ornamental lawns. Since dermal hazard
has not been identified for isofetamid, a
quantitative assessment for dermal
exposure is not necessary and the only
exposure scenarios quantitatively
assessed are for children 1 to <2 years
old who may experience short-term
incidental oral exposure to isofetamid
from treated turf. Intermediate-term
incidental oral post-application
exposures are possible (i.e., from soil
ingestion due to the persistence of
isofetamid); however, the short-term
incidental oral exposures are protective
of the possible intermediate-term
incidental oral exposures because the
POD for both durations is the same.
Post-application inhalation exposure is
expected to be negligible for the
proposed residential uses.
The post-application incidental oral
MOE values were calculated based on
the scenario of liquid application of
isofetamid to turf. Post-application risk
estimates for all incidental oral
scenarios are not of concern (MOEs
range from 5,900 to 4,000,000). The
incidental oral scenarios (i.e., hand-tomouth and object-to-mouth) should be
considered inter-related and it is likely
that they occur interspersed amongst
E:\FR\FM\14JNR1.SGM
14JNR1
27152
Federal Register / Vol. 82, No. 113 / Wednesday, June 14, 2017 / Rules and Regulations
each other across time. However,
combining these scenarios would be
overly-conservative because of the
conservative nature of each individual
assessment. Incidental oral risk
estimates are highly conservative
because the short- and intermediateterm incidental oral POD is based on a
90-day exposure duration which
represents daily exposure for 90 days.

standard assumptions and generic
inputs for residential exposures may be
found at https://www2.epa.gov/pesticidescience-and-assessing-pesticide-risks/
standard-operating-proceduresresidential-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 https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.

D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
Food Quality Protection Act Safety
Factor (FQPA SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
2. Prenatal and postnatal sensitivity.
There is no evidence of developmental
toxicity or reproductive susceptibility,
and there are no residual uncertainties
concerning pre- or post-natal toxicity or
exposure.
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 isofetamid
is complete.
ii. There is no indication that
isofetamid is a neurotoxic chemical and
there is no need for a developmental
neurotoxicity study or additional UFs 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
tolerance level 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 post
application exposure of children as well
as incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by isofetamid.
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 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 risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
PO 00000
Frm 00048
Fmt 4700
Sfmt 4700
that chronic exposure to isofetamid
from food and water will utilize 4.0% of
the cPAD for children (1–2 years old),
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
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 exposures result in an
aggregate MOE of 1,600 for children (1–
2 years old). Because EPA’s level of
concern for isofetamid is a MOE of 100
or below, this MOE is 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, isofetamid is not
registered for any use patterns that
would result in intermediate-term
residential exposure. Intermediate-term
risk is assessed based on intermediateterm 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.

IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
liquid chromatography with tandem
mass spectrometry (LC–MS/MS) method
is available to enforce the tolerance
expression. Multiresidue methods
testing data have been submitted for
isofetamid and GPTC. The data indicate
that multiresidue methods are not
suitable for analysis of isofetamid and
GPTC, so the multiresidue methods
cannot serve as enforcement methods.
The multiresidue data have been
forwarded to the Food and Drug
Administration (FDA).
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 MRLs
for isofetamid. There are no Canadian,
Codex, or Mexican maximum residue
limits (MRLs) for isofetamid in/on the
commodities included in this petition.
mstockstill on DSK30JT082PROD with RULES
C. Revisions to Petitioned-For
Tolerances
All tolerance levels are based upon
the Organization for Economic Cooperation and Development’s (OECD)
tolerance calculation procedures. Thus,
the tolerance levels established in this
notice for isofetamid in/on bushberry,
subgroup 13–07B; cherry, subgroup 12–
12A; plum, prune, dried; dried shelled
pea and bean, except soybean, subgroup
6C; and succulent shelled pea and bean,
subgroup 6B are lower than those
requested by the petitioner. The
tolerance levels established in this
notice for caneberry, subgroup 13–07A
and fruit, small vine climbing, except
grape, subgroup 13–07E are higher than
those requested by the petitioner based
on the OECD calculation procedures.
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
Additionally, the Agency has
determined that tolerances requested for
residues in livestock commodities are
not required. These tolerances fall under
40 CFR 180.6(a)(3) regarding secondary
residues in livestock commodities, i.e.,
it is not possible to establish with
certainty whether finite residues will be
incurred, but there is no reasonable
expectation of finite residues.
The following commodity definitions
have been corrected: Bushberry
subgroup 13–07B; fruit, small vine
climbing, except grape, subgroup 13–
07E; pea and bean, dried shelled, except
soybean, subgroup 6C; and pea and
bean, succulent shelled, subgroup 6B.
V. Conclusion
Therefore, tolerances are established
for residues of isofetamid, in or on
apple, wet pomace, at 2.0 parts per
million (ppm); bushberry subgroup 13–
07B at 5.0 ppm; caneberry subgroup 13–
07A at 4.0 ppm; cherry subgroup 12–
12A at 4.0 ppm; fruit, pome, group 11–
10 at 0.60 ppm; fruit, small vine
climbing, except grape, subgroup 13–
07E at 10.0 ppm; pea and bean, dried
shelled, except soybean, subgroup 6C, at
0.040 ppm; pea and bean, succulent
shelled, subgroup 6B, at 0.030 ppm;
peach subgroup 12–12B at 3.0 ppm;
plum, prune, dried at 1.50 ppm; plum
subgroup 12–12C at 0.80 ppm; and
vegetable, legume, edible podded,
subgroup 6A at 1.50 ppm. Additionally,
the existing time-limited tolerances are
being removed for both Caneberry
subgroup 13–07A at 4.0 ppm, and for
Bushberry subgroup 13–07B at 5.0 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). 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
PO 00000
Frm 00049
Fmt 4700
Sfmt 4700
27153
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
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).

ACTION: Final rule.
AGENCY:
The Environmental Protection
Agency (EPA) is promulgating
technology-based pretreatment
standards under the Clean Water Act to
reduce discharges of mercury from
dental offices into municipal sewage
treatment plants known as publicly
owned treatment works (POTWs). This
final rule requires dental offices to use
amalgam separators and two best
management practices recommended by
the American Dental Association (ADA).
This final rule includes a provision to
significantly reduce and streamline the
oversight and reporting requirements in
EPA’s General Pretreatment Regulations
that would otherwise apply as a result
of this rulemaking. EPA expects
compliance with this final rule will
annually reduce the discharge of
mercury by 5.1 tons as well as 5.3 tons
of other metals found in waste dental
amalgam to POTWs.
DATES: The final rule is effective on July
14, 2017. The compliance date, meaning
the date that existing sources subject to
the rule must comply with the standards
in this rule is July 14, 2020. After the
effective date of the rule, new sources
subject to this rule must comply
immediately with the standards in this
rule. In accordance with 40 CFR part 23,
this regulation shall be considered
issued for purposes of judicial review at
1 p.m. Eastern time on June 28, 2017.
Under section 509(b)(1) of the CWA,
judicial review of this regulation can be
had only by filing a petition for review
in the U.S. Court of Appeals within 120
days after the regulation is considered
issued for purposes of judicial review.
Under section 509(b)(2), the
requirements in this regulation may not
be challenged later in civil or criminal
proceedings brought by EPA to enforce
these requirements.

II. Summary of Petitioned-For Tolerance
In the Federal Register of February 7, 2017 (82 FR 9555) (FRL-9956-
86), 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
6F8457) by ISK Biosciences Corporation, 7470 Auburn Rd., Suite A,
Concord, OH 44077. The petition requested that 40 CFR 180.681 be
amended by establishing tolerances for residues of 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 3.0 parts per million (ppm); apple, wet pomace, at 2.0 ppm;
bushberry, subgroup 13-07B at 6.0 ppm; cattle, fat at 0.01 ppm; cattle,
meat byproducts at 0.01 ppm; cherry subgroup 12-12A at 5.0 ppm; fruit,
pome, group 11-10 at 0.6 ppm; fruit, small vine climbing, except grape,
subgroup 13-7E at 9.0 ppm; goat, fat at 0.01 ppm; goat, meat byproducts
at 0.01 ppm; horse, fat at 0.01 ppm; horse, meat byproducts at 0.01
ppm; pea and bean, dried shelled, except soybean, subgroup 6C, except
cowpea and field pea at 0.05 ppm; pea and bean, succulent shelled,
subgroup 6B, except cowpea at 0.04 ppm; peach subgroup 12-12B at 3.0
ppm; plum, prune, dried at 3.5 ppm; plum subgroup 12-12C at 0.8 ppm;
sheep, fat at 0.01 ppm; sheep, meat byproducts at 0.01 ppm; and
vegetable, legume, edible podded, subgroup 6A at 1.5 ppm. That document
referenced a summary of the petition prepared by ISK Biosciences
Corporation, the registrant, which is available in the docket, https://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 has
revised some of the proposed tolerances; determined that tolerances for
residues in livestock commodities are not required; and corrected some
of the commodity definitions. The reason for these changes are
explained in Unit IV.D.
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 isofetamid including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with isofetamid 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 toxicology database is complete for isofetamid. In
repeated dose studies, the liver was the primary target organ in the
rat, mouse, and dog, as indicated by increased liver weights, changes
in the clinical chemistry values, and liver hypertrophy. A second
target organ was the thyroid in the rat and dog, as indicated by
changes in thyroid weights and histopathology. Adrenal weight changes
were observed in the subchronic rat and dog studies. In the rat and
dog, the dose levels where toxicity was observed were similar or higher
in the chronic studies compared with the respective subchronic studies,
showing an absence of progression of liver toxicity with time. There
was no evidence of carcinogenicity in the rat or mouse cancer studies;
the mutagenicity battery was negative. There are no genotoxicity,
neurotoxicity, or immunotoxicity concerns observed in the available
toxicity studies. Developmental toxicity was not observed in the rat or
rabbit, and offspring effects such as decreased body weight were seen
only in the presence of parental toxicity in the multi-generation rat
study. Isofetamid is classified as ``Not Likely to be Carcinogenic to
Humans'' based on the absence of increased tumor incidence in
acceptable/guideline carcinogenicity studies in rats and mice.
Isofetamid is not acutely toxic; it is classified as Toxicity Category
III for acute oral and dermal exposure, and Toxicity Category IV for
inhalation exposure. Furthermore, it is not irritating to the eye or
skin, and it is not a dermal sensitizer.
Specific information on the studies received and the nature of the
adverse effects caused by isofetamid as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies are can be found at https://www.regulations.gov in document Isofetamid. Aggregate Human Health Risk

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
[[Page 27151]]
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 https://www2.epa.gov/pesticide-science-and-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 45440) (FRL-
9923-86).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to isofetamid, EPA considered exposure under the petitioned-
for tolerances 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. 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 such effects were
identified in the toxicological studies for isofetamid; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. An unrefined chronic (food and drinking
water) dietary assessment was conducted for all registered and proposed
food uses of isofetamid using the Dietary Exposure Evaluation Model
software with the Food Commodity Intake Database (DEEM-FCID) Version
3.16. This software uses 2003-2008 food consumption data from the U.S.
Department of Agriculture's (USDA's) National Health and Nutrition
Examination Survey, What We Eat in America (NHANES/WWEIA). The chronic
dietary (food and drinking water) exposure assessment for isofetamid
incorporated existing tolerance-level residues, Agency-recommended
tolerance-level residues for proposed tolerances, DEEM default
processing factors, and 100 PCT (percent crop treated). Some tolerance
levels were adjusted to include residues of the metabolite, GPTC (a
residue of concern for risk assessment). DEEM default processing
factors were used for dried apples, apple juice, dried pear, cherry
juice, dried apricot, dried peach, plum, prune juice, cranberry juice,
and grape juice. The EDWC of 110 microgram/Liter ([micro]g/L) was
incorporated directly into the dietary assessment.
iii. Cancer. Based on the data summarized in Unit III.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 anticipated residue and/or PCT information in the
dietary assessment for isofetamid. Tolerance level residues and/or 100
PCT were assumed for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for 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 https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the Pesticide Flooded Application Model 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 parts per billion (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 value of 110 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).
Isofetamid is currently registered for the following uses that
could result in residential exposures: Turfgrass including golf
courses, residential lawns, and recreational turfgrass. It is currently
under review for registering use on ornamental plants. The proposed
ornamental use is not intended for homeowner use and therefore a
quantitative residential handler assessment was not conducted.
Additionally, post-application exposures for adults and children are
expected to be negligible. However, the existing turf use may result in
short- and intermediate-term exposures. Residential exposure may occur
by the dermal and incidental oral routes of exposures following the
application of isofetamid on residential turf. However, since dermal
hazard has not been identified for isofetamid, the only exposure
scenario quantitatively assessed is for post-application incidental
oral (for children 1 to <2 years old). These exposures have been
assessed with current policies, which include the Agency's 2012
Residential Standard Operating Procedures (https://www.epa.gov/pesticides/science/residential-exposure-sop.html) along with policy
changes for body weight assumptions.
Even though a previous risk assessment identified residential
handler risk estimates for use in aggregate assessment, based on
current policy and that isofetamid products are intended for sale/use
to/by professional applicators, residential handler exposure
assessments for turf are no longer applicable to the isofetamid
aggregate risk assessment. Therefore, the aggregate assessment for this
action only includes a risk contribution from residential post-
application incidental oral exposure for children 1 to <2 years old.
There is the potential for post-application exposure for
individuals as a result of being in an environment that has been
previously treated with isofetamid such as residential ornamental
lawns. Since dermal hazard has not been identified for isofetamid, a
quantitative assessment for dermal exposure is not necessary and the
only exposure scenarios quantitatively assessed are for children 1 to
<2 years old who may experience short-term incidental oral exposure to
isofetamid from treated turf. Intermediate-term incidental oral post-
application exposures are possible (i.e., from soil ingestion due to
the persistence of isofetamid); however, the short-term incidental oral
exposures are protective of the possible intermediate-term incidental
oral exposures because the POD for both durations is the same. Post-
application inhalation exposure is expected to be negligible for the
proposed residential uses.
The post-application incidental oral MOE values were calculated
based on the scenario of liquid application of isofetamid to turf.
Post-application risk estimates for all incidental oral scenarios are
not of concern (MOEs range from 5,900 to 4,000,000). The incidental
oral scenarios (i.e., hand-to-mouth and object-to-mouth) should be
considered inter-related and it is likely that they occur interspersed
amongst
[[Page 27152]]
each other across time. However, combining these scenarios would be
overly-conservative because of the conservative nature of each
individual assessment. Incidental oral risk estimates are highly
conservative because the short- and intermediate-term incidental oral
POD is based on a 90-day exposure duration which represents daily
exposure for 90 days. Further information regarding EPA standard
assumptions and generic inputs for residential exposures may be found
at https://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 https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the Food Quality
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA
either retains the default value of 10X, or uses a different additional
safety factor 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, and there are no
residual uncertainties concerning pre- or post-natal toxicity or
exposure.
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 isofetamid is complete.
ii. There is no indication that isofetamid is a neurotoxic chemical
and there is no need for a developmental neurotoxicity study or
additional UFs 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 tolerance level 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 post application exposure of
children as well as incidental oral exposure of toddlers. These
assessments will not underestimate the exposure and risks posed by
isofetamid.
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 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 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 4.0% of the cPAD for
children (1-2 years old), 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
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 exposures result in an aggregate MOE of 1,600 for
children (1-2 years old). Because EPA's level of concern for isofetamid
is a MOE of 100 or below, this MOE is 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,
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.
[[Page 27153]]
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology liquid chromatography with tandem
mass spectrometry (LC-MS/MS) method is available to enforce the
tolerance expression. Multiresidue methods testing data have been
submitted for isofetamid and GPTC. The data indicate that multiresidue
methods are not suitable for analysis of isofetamid and GPTC, so the
multiresidue methods cannot serve as enforcement methods. The
multiresidue data have been forwarded to the Food and Drug
Administration (FDA).
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 MRLs for isofetamid. There are no
Canadian, Codex, or Mexican maximum residue limits (MRLs) for
isofetamid in/on the commodities included in this petition.
C. Revisions to Petitioned-For Tolerances
All tolerance levels are based upon the Organization for Economic
Co-operation and Development's (OECD) tolerance calculation procedures.
Thus, the tolerance levels established in this notice for isofetamid
in/on bushberry, subgroup 13-07B; cherry, subgroup 12-12A; plum, prune,
dried; dried shelled pea and bean, except soybean, subgroup 6C; and
succulent shelled pea and bean, subgroup 6B are lower than those
requested by the petitioner. The tolerance levels established in this
notice for caneberry, subgroup 13-07A and fruit, small vine climbing,
except grape, subgroup 13-07E are higher than those requested by the
petitioner based on the OECD calculation procedures.
Additionally, the Agency has determined that tolerances requested
for residues in livestock commodities are not required. These
tolerances fall under 40 CFR 180.6(a)(3) regarding secondary residues
in livestock commodities, i.e., it is not possible to establish with
certainty whether finite residues will be incurred, but there is no
reasonable expectation of finite residues.
The following commodity definitions have been corrected: Bushberry
subgroup 13-07B; fruit, small vine climbing, except grape, subgroup 13-
07E; pea and bean, dried shelled, except soybean, subgroup 6C; and pea
and bean, succulent shelled, subgroup 6B.
V. Conclusion
Therefore, tolerances are established for residues of isofetamid,
in or on apple, wet pomace, at 2.0 parts per million (ppm); bushberry
subgroup 13-07B at 5.0 ppm; caneberry subgroup 13-07A at 4.0 ppm;
cherry subgroup 12-12A at 4.0 ppm; fruit, pome, group 11-10 at 0.60
ppm; fruit, small vine climbing, except grape, subgroup 13-07E at 10.0
ppm; pea and bean, dried shelled, except soybean, subgroup 6C, at 0.040
ppm; pea and bean, succulent shelled, subgroup 6B, at 0.030 ppm; peach
subgroup 12-12B at 3.0 ppm; plum, prune, dried at 1.50 ppm; plum
subgroup 12-12C at 0.80 ppm; and vegetable, legume, edible podded,
subgroup 6A at 1.50 ppm. Additionally, the existing time-limited
tolerances are being removed for both Caneberry subgroup 13-07A at 4.0
ppm, and for Bushberry subgroup 13-07B at 5.0 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). 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 Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
