II. Petition for Tolerance
In the Federal Register of August 22,
2007 (72 FR 47010) (FRL–8142–5)
(Docket ID number EPA-HQ-OPP-2007–
0536, EPA issued a notice pursuant to
section 408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide petition (PP 6E7074) by IR-4,
500 College Road East, Suite 201 W,
Princeton, NJ 08540–6635. The petition
requested that 40 CFR 180.421 be
amended by establishing tolerances for
residues of the fungicide fenarimol,
E:\FR\FM\23DER1.SGM

alpha-(2-chlorophenyl)-alpha-(4chlorophenyl)-5-pyrimidinemethanol,
in or on hop at 1.0 parts per million
(ppm). That notice referenced a
summary of the petition prepared on
behalf of IR-4 by Gowan Company, the
registrant, which is available to the
public in the docket, https://
www.regulations.gov. There were no
comments received in response to the
notice of filing.
In the Federal Register of June 6, 2007
(72 FR 31221) (FRL–8122–7) (Docket ID
number EPA-HQ-OPP-2007–0097). EPA
issued a proposed rule pursuant to
sections 408(e) of FFDCA, 21 U.S.C.
346a(e). The rule proposed that 40 CFR
180.421 be amended by increasing the
tolerance for residues of the fungicide
fenarimol, alpha-(2-chlorophenyl)alpha-(4-chlorophenyl)-5pyrimidinemethanol, in or on apple
from 0.1 ppm to 0.3 ppm. EPA proposed
the tolerance increase in order to
harmonize with a Codex Maximum
Residue Limit (MRL) of 0.3 ppm on
apples. The proposal explained the
basis for EPA’s conclusion that there is
a reasonable certainty that no harm will
result to the general population, or to
infants and children, from aggregate
exposure to fenarimol, including
exposure under the amended apple
tolerance. The proposal established a
60–day public comment period.
Comments were received in response to
the proposed rule. EPA’s response to
these comments is discussed in Unit
IV.C.
Based upon review of the data
supporting the petition, EPA has revised
the proposed tolerance on hop, dried
cones. The reason for this change is
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
VerDate Nov<24>2008
13:48 Dec 22, 2009
Jkt 220001
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’
Consistent with section 408(b)(2)(D)
of FFDCA, and the factors specified in
section 408(b)(2)(D) of FFDCA, 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 the petitioned-for
tolerances for residues of fenarimol on
hop, dried cones at 5.0 ppm and apple
at 0.3 ppm. EPA’s assessment of
exposures and risks associated with
establishing tolerances 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.
Fenarimol has a relatively low order
of acute toxicity via the oral, dermal,
and inhalation routes of exposure. It is
not a dermal sensitizer but causes
corneal opacity in rabbits. Chronic
studies indicated that the liver is a
target organ for toxicity. Liver toxicity
was manifested by liver weight
increases and the presence of ‘‘fatty
liver’’ in rats. In dogs, increased liver
weights and increases in serum
enzymes, indicative of liver toxicity,
were noted. Additionally, reproduction
and developmental studies showed that
fenarimol inhibited aromatase, an
enzyme involved in the conversion of
androgens to estrogens. Two acceptable
rodent carcinogenicity studies showed
no evidence of significant tumor
increases; therefore, fenarimol has been
classified as ‘‘not likely to be
carcinogenic to humans.’’ Additionally,
the toxicity database indicates no
evidence of mutagenicity or
neurotoxicity.
The toxicology data for fenarimol
provides no indication of increased
susceptibility, as compared to adults, of
rat and rabbit fetuses to in utero
exposure in developmental studies.
Developmental kidney effects
(hydronephrosis) in the rat were shown
to be reversible. The multi-generation
reproduction study in rats indicates that
fenarimol causes reduced fertility in
males and dystocia in females; these
effects were attributed to the inhibition
of aromatase. Decreased litter size was
also noted in the study.

Non-guideline reproductive
performance studies in mice, guinea
pigs, and rabbits resulted in decreased
reproductive performance in male mice,
but no such effect in the guinea pig or
rabbit studies. A pubertal assay
conducted in female rats resulted in
decreased T4 thyroid hormone coupled
with an increase in circulating thyroid
stimulating hormone (TSH) levels. A
female rat uterotrophic assay resulted in
significant uterine weight increases
accompanied by increased serum
follicle stimulating hormone (FSH)
levels and decreased serum T3 levels.
Specific information on the studies
received and the nature of the adverse
effects caused by fenarimol as well as
the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://
www.regulations.gov in document
‘‘Fenarimol. Human Health Risk
Assessment for the Proposed Food Use
of Fenarimol on Hops,’’ pages 46 to 49
in docket ID number EPA–HQ–OPP–
2007–0536.
B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, a toxicological point of departure
(POD) is identified as the basis for
derivation of reference values for risk
assessment. The POD may be defined as
the highest dose at which no adverse
effects are observed (the NOAEL) in the
toxicology study identified as
appropriate for use in risk assessment.
However, if a NOAEL cannot be
determined, the lowest dose at which
adverse effects of concern are identified
(the LOAEL) or a benchmark dose
(BMD) approach is sometimes used for
risk assessment. Uncertainty/safety
factors (UFs) are used in conjunction
with the POD to take into account
uncertainties inherent in the
extrapolation from laboratory animal
data to humans and in the variations in
sensitivity among members of the
human population as well as other
unknowns. Safety is assessed for acute
and chronic dietary risks by comparing
aggregate food and water exposure to
the pesticide to the acute population
adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The
aPAD and cPAD are calculated by
dividing the POD by all applicable UFs.
Aggregate short-term, intermediate-term,
and chronic-term risks are evaluated by
comparing food, water, and residential
exposure to the POD to ensure that the
margin of exposure (MOE) called for by
the product of all applicable UFs is not
exceeded. This latter value is referred to
as the level of concern (LOC).

Federal Register / Vol. 74, No. 245 / Wednesday, December 23, 2009 / Rules and Regulations
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 greater than that 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://www.epa.gov/
pesticides/factsheets/riskassess.htm.

endpoints for fenarimol used for human
risk assessment can be found at https://

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to fenarimol, EPA considered
exposure under the petitioned-for
tolerances as well as all existing
fenarimol tolerances in 40 CFR 180.421.
EPA assessed dietary exposures from
fenarimol 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 fenarimol;
therefore, a quantitative acute dietary
exposure assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the United States Department of
Agriculture (USDA) 1994–1996 and
1998 Continuing Surveys of Food
Intakes by Individuals (CSFII). The
chronic dietary exposure assessment for
fenarimol is refined using anticipated
residues (ARs) from field trial data,
processing factors, and percent crop
treated (PCT) data.
ARs based on Food and Drug
Administration (FDA) monitoring data
were used for apples, bananas, cherries,
grapes, and pears. Tolerance values
were assumed for foods covered by all
additional tolerances. PCT data was
used for apples, cherries, grapes, and
pears. Dietary Exposure Evalution
Model (DEEM) default processing
factors were used for all food
commodities, except apple juice, pear
juice, grape juice, and raisins, which
used factors derived from processing
studies.

Jkt 220001
iii. Cancer. Based on the absence of
significant tumor increases in two
adequate rodent carcinogenicity studies,
EPA has classified fenarimol as ‘‘not
likely to be carcinogenic to humans.’’
Therefore, a quantitative exposure
assessment to evaluate cancer risk is
unnecessary.
iv. Anticipated residue and PCT
information. Section 408(b)(2)(E) of
FFDCA authorizes EPA to use available
data and information on the AR levels
of pesticide residues in food and the
actual levels of pesticide residues that
have been measured in food. If EPA
relies on such information, EPA must
require pursuant to FFDCA section
408(f)(1) that data be provided 5 years
after the tolerance is established,
modified, or left in effect, demonstrating
that the levels in food are not above the
levels anticipated. For the present
action, EPA will issue such Data CallIns as are required by FFDCA section
408(b)(2)(E) and authorized under
FFDCA section 408(f)(1). Data will be
required to be submitted no later than
5 years from the date of issuance of
these tolerances.
Section 408(b)(2)(F) of FFDCA states
that the Agency may use data on the
actual percent of food treated for
assessing chronic dietary risk only if:
• Condition a. The data used are
reliable and provide a valid basis to
show what percentage of the food
derived from such crop is likely to
contain the pesticide residue.
• Condition b. The exposure estimate
does not underestimate exposure for any
significant subpopulation group.
• Condition c. Data are available on
pesticide use and food consumption in
a particular area, the exposure estimate
does not understate exposure for the
population in such area.
In addition, the Agency must provide
for periodic evaluation of any estimates
used. To provide for the periodic
evaluation of the estimate of PCT as
required by FFDCA section 408(b)(2)(F),
EPA may require registrants to submit
data on PCT.
The Agency used PCT information as
follows:
Apples, 20%; cherries, 15%; grapes,
25%; and pears, 10%.
In most cases, EPA uses available data
from USDA/National Agricultural
Statistics Service (NASS), proprietary
market surveys, and the National
Pesticide Use Database for the chemical/
crop combination for the most recent 6
years. EPA uses an average PCT for
chronic dietary risk analysis. The
average PCT figure for each existing use
is derived by combining available
public and private market survey data
for that use, averaging across all
PO 00000
Frm 00040
Fmt 4700
Sfmt 4700
observations, and rounding to the
nearest 5%, except for those situations
in which the average PCT is less than
one. In those cases, 1% is used as the
average PCT and 2.5% is used as the
maximum PCT. EPA uses a maximum
PCT for acute dietary risk analysis. The
maximum PCT figure is the highest
observed maximum value reported
within the recent 6 years of available
public and private market survey data
for the existing use and rounded up to
the nearest multiple of 5%.
The Agency believes that the three
conditions discussed in Unit III.C.1.iv.
have been met. With respect to
Condition a, PCT estimates are derived
from Federal and private market survey
data, which are reliable and have a valid
basis. The Agency is reasonably certain
that the percentage of the food treated
is not likely to be an underestimation.
As to Conditions b and c, regional
consumption information and
consumption information for significant
subpopulations is taken into account
through EPA’s computer-based model
for evaluating the exposure of
significant subpopulations including
several regional groups. Use of this
consumption information in EPA’s risk
assessment process ensures that EPA’s
exposure estimate does not understate
exposure for any significant
subpopulation group and allows the
Agency to be reasonably certain that no
regional population is exposed to
residue levels higher than those
estimated by the Agency. Other than the
data available through national food
consumption surveys, EPA does not
have available reliable information on
the regional consumption of food to
which fenarimol may be applied in a
particular area.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for the total residues of concern,
including parent fenarimol and its
organic degradates (U–1, U–2, U–6, and
U–7), in drinking water. These
simulation models take into account
data on the physical, chemical, and fate/
transport characteristics of fenarimol.
Further information regarding EPA
drinking water models used in pesticide
exposure assessment can be found at
https://www.epa.gov/oppefed1/models/
water/index.htm.
Based on the Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening
Concentration in Ground Water (SCIGROW) models, the estimated drinking
water concentrations (EDWCs) of
fenarimol for surface water are
estimated to be 66 parts per billion

23DER1
Federal Register / Vol. 74, No. 245 / Wednesday, December 23, 2009 / Rules and Regulations
cprice-sewell on DSKHWCL6B1PROD with RULES
(ppb) for chronic exposures. For ground
water, the estimated drinking water
concentration is 19 ppb.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 66 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 nonoccupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets).
Fenarimol is currently registered for
use on professionally managed turf
areas, such as stadia and golf course
tees, greens, and fairways. Short-term
postapplication dermal exposure to
adult golfers is possible.
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 fenarimol to share
a common mechanism of toxicity with
any other substances, and fenarimol
does not appear to produce a toxic
metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that fenarimol does not have a
common mechanism of toxicity with
other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
Food Quality Protection Act (FQPA)
safety factor (SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
VerDate Nov<24>2008
13:48 Dec 22, 2009
Jkt 220001
additional SF when reliable data
available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity.
The database for prenatal
developmental (in rats and rabbits) and
reproductive (in rats) toxicity is
considered complete and includes
special studies in addition to
conventional guideline studies. The rat
developmental study showed evidence
of hydronephrosis in fetuses at dose
levels equal to or possibly lower than
doses causing maternal toxicity;
however, a special study showed this
effect to be reversible and therefore not
considered an adverse effect.
Additionally, the decreased live born
litter size and survival indices in the rat
multi-generation reproduction study are
considered to be secondary
consequenies of parental effects (e.g.
dystocia and fertility), and is not an
indicator of increased susceptibility.
Therefore, there is no evidence of
increased susceptibility of fetuses
following in utero exposure in the rat or
rabbit developmental toxicity study or
of offspring following prenatal and
postnatal exposure in the rat
reproduction study, and there are no
concerns or residual uncertainties for
prenatal and/or postnatal toxicity.
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 fenarimol
is complete except for immunotoxicity
testing. Recent changes to 40 CFR part
158 make immunotoxicity testing
(OPPTS Harmonized Test Guideline
870.7800) required for pesticide
registration; however, the available data
for fenarimol do not show potential for
immunotoxicity. Consequently, the EPA
believes the existing data are sufficient
for endpoint selection for exposure/risk
assessment scenarios and for evaluation
of the requirements under the FQPA,
and an additional database UF does not
need to be applied.
ii. There is no indication that
fenarimol 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
fenarimol 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.

residues or ARs that are based on
reliable field trial data, and factors
derived from processing studies (for
apple juice, pear juice, grape juice, and
raisins) or DEEM default processing
factors. For several currently registered
commodities, the chronic assessment
also utilized PCT data that have a valid
basis and are considered to be reliable.
EPA made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to fenarimol in drinking water. EPA
made similarly conservative
assumptions to assess postapplication
exposures. These assessments will not
underestimate the exposure and risks
posed by fenarimol.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic pesticide exposures are safe by
comparing aggregate exposure estimates
to the aPAD and cPAD. The aPAD and
cPAD represent the highest safe
exposures, taking into account all
appropriate SFs. EPA calculates the
aPAD and cPAD by dividing the POD by
all applicable UFs. For linear cancer
risks, EPA calculates the probability of
additional cancer cases given the
estimated aggregate exposure. Shortterm, intermediate-term, and chronicterm risks are evaluated by comparing
the estimated aggregate food, water, and
residential exposure to the POD to
ensure that the MOE called for by the
product of all applicable UFs is not
exceeded.
1. Acute risk. An acute aggregate risk
assessment takes into account exposure
estimates from acute 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, fenarimol 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 fenarimol from
food and water will utilize 76% of the
cPAD for infants less than 1–year 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
fenarimol 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). Fenarimol is currently
registered for use on professionally
managed turf, including stadia and golf
E:\FR\FM\23DER1.SGM
23DER1
68172
Federal Register / Vol. 74, No. 245 / Wednesday, December 23, 2009 / Rules and Regulations
course tees, greens, and fairways, which
could result in short-term
postapplication dermal exposure to
golfers. The Agency has determined that
it is appropriate to aggregate chronic
exposure through food and water with
short-term residential exposures to
fenarimol.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures aggregated result
in aggregate MOEs of 8,800 for adults
20–49 years old. EPA has determined
that this assessment adequately
estimates the risk for youth golfers as
well. As the aggregate MOE is greater
than 1,000 (the LOC), short-term
aggregate exposure to fenarimol is not of
concern to EPA.
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).
Fenarimol is not registered for any use
patterns that would result in
intermediate-term residential exposure.
Therefore, the intermediate-term
aggregate risk is the sum of the risk from
exposure to fenarimol through food and
water, which has already been
addressed, and will not be greater than
the chronic aggregate risk.
5. Aggregate cancer risk for U.S.
population. As discussed in Unit
III.C.1.iii., EPA has classified fenarimol
as ‘‘not likely to be carcinogenic to
humans,’’ and it 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 fenarimol
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
cprice-sewell on DSKHWCL6B1PROD with RULES
Adequate enforcement methodology,
gas chromatography (GC) with an
electrolytic conductivity detector (ECD),
is available to enforce the tolerance
expression, and is published in the
Pesticide Analytical Manual (PAM) Vol.
II (Method R039).
B. International Residue Limits
Residue definitions are harmonized
between the United States, Codex, and
Mexico. In order to harmonize with a
Codex MRL of 0.3 ppm for apples, EPA
is increasing the tolerance for residues
of apples from 0.1 ppm to 0.3 ppm.
Additionally, a Codex MRL exists on
VerDate Nov<24>2008
13:48 Dec 22, 2009
Jkt 220001
hop dried cones at 5.0 ppm. The Agency
is establishing a tolerance on hop, dried
cones at 5.0 ppm to harmonize MRLs
between the United States and Codex
for this commodity.
C. Response to Comments
EPA received one comment to the
proposed rule of June 6, 2007, which
made a general objection to the presence
of any pesticide residues on crops and
stated that EPA should set no pesticide
tolerance greater than zero. The Agency
understands the commenter’s concerns
and recognizes that some individuals
believe that pesticides should be banned
completely. However, the existing legal
framework provided by section 408 of
the FFDCA states that tolerances greater
than zero may be set when it has been
demonstrated that the pesticide meets
the safety standard imposed by that
statute. This citizen’s comment appears
to be directed at the underlying statute
and not EPA’s implementation of it; the
citizen has made no contention that
EPA has acted in violation of the
statutory framework.
D. Revisions to Petitioned-For
Tolerances
Based upon review of the data
supporting the IR-4 petition, EPA
revised the proposed tolerance for hop,
dried cones from 1.0 ppm to 1.2 ppm.
EPA revised the tolerance level based on
analysis of the residue field trial data
using the Agency’s Tolerance
Spreadsheet in accordance with the
Agency’s ‘‘Guidance for Setting
Pesticide Tolerances Based on Field
Trial Data.’’ However, it was discovered
that a Codex MRL exists on hops, dried
cones at 5.0 ppm. As a result, EPA has
increased the hop, dried cones tolerance
from 1.2 ppm to 5.0 ppm to harmonize
with Codex. The potentially greater
exposure under this increased tolerance
value was included in EPA’s fenarimol
risk assessment.
V. Conclusion
Therefore, a tolerance is established
for residues of fenarimol, alpha-(2chlorophenyl)-alpha-(4-chlorophenyl)-5pyrimidinemethanol, in or on hop,
dried cones at 5.0 ppm. Additionally,
the established tolerance of fenarimol in
or on apple is increased from 0.1 ppm
to 0.3 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under section 408(d) and 408(e) of
FFDCA following an agency initiated
proposal. The Office of Management
and Budget (OMB) has exempted these
types of actions from review under
PO 00000
Frm 00042
Fmt 4700
Sfmt 4700
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 section 408(d) of FFDCA, such as
the tolerance in this final rule on hops,
dried cones, 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 to this
tolerance. The tolerance on apples,
however, was initiated by an EPA
proposal and thus the RFA is
applicable. Pursuant to the RFA, the
Agency hereby certifies that the apple
tolerance will not have significant
negative economic impact on a
substantial number of small entities.
Establishing a pesticide tolerance or an
exemption from the requirement of a
pesticide tolerance is, in effect, the
removal of a regulatory restriction on
pesticide residues in food and thus such
an action will not have any negative
economic impact on any entities,
including small entities.
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 section 408(n)(4) of FFDCA. 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,
E:\FR\FM\23DER1.SGM
23DER1
Federal Register / Vol. 74, No. 245 / Wednesday, December 23, 2009 / Rules and Regulations
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) (Public Law 104–4).
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), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).
VII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. 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 this final rule in the
Federal Register. This final rule is not
a ‘‘major rule’’ as defined by 5 U.S.C.
804(2).

II. Petition for Tolerance
In the Federal Register of August 22, 2007 (72 FR 47010) (FRL-8142-
5) (Docket ID number EPA-HQ-OPP-2007-0536, EPA issued a notice pursuant
to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the
filing of a pesticide petition (PP 6E7074) by IR-4, 500 College Road
East, Suite 201 W, Princeton, NJ 08540-6635. The petition requested
that 40 CFR 180.421 be amended by establishing tolerances for residues
of the fungicide fenarimol,
[[Page 68169]]
alpha-(2-chlorophenyl)-alpha-(4-chlorophenyl)-5-pyrimidinemethanol, in
or on hop at 1.0 parts per million (ppm). That notice referenced a
summary of the petition prepared on behalf of IR-4 by Gowan Company,
the registrant, which is available to the public in the docket, https://www.regulations.gov. There were no comments received in response to the
notice of filing.
In the Federal Register of June 6, 2007 (72 FR 31221) (FRL-8122-7)
(Docket ID number EPA-HQ-OPP-2007-0097). EPA issued a proposed rule
pursuant to sections 408(e) of FFDCA, 21 U.S.C. 346a(e). The rule
proposed that 40 CFR 180.421 be amended by increasing the tolerance for
residues of the fungicide fenarimol, alpha-(2-chlorophenyl)-alpha-(4-
chlorophenyl)-5-pyrimidinemethanol, in or on apple from 0.1 ppm to 0.3
ppm. EPA proposed the tolerance increase in order to harmonize with a
Codex Maximum Residue Limit (MRL) of 0.3 ppm on apples. The proposal
explained the basis for EPA's conclusion that there is a reasonable
certainty that no harm will result to the general population, or to
infants and children, from aggregate exposure to fenarimol, including
exposure under the amended apple tolerance. The proposal established a
60-day public comment period. Comments were received in response to the
proposed rule. EPA's response to these comments is discussed in Unit
IV.C.
Based upon review of the data supporting the petition, EPA has
revised the proposed tolerance on hop, dried cones. The reason for this
change is 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 section 408(b)(2)(D) of FFDCA, and the factors
specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for
tolerances for residues of fenarimol on hop, dried cones at 5.0 ppm and
apple at 0.3 ppm. EPA's assessment of exposures and risks associated
with establishing tolerances 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.
Fenarimol has a relatively low order of acute toxicity via the
oral, dermal, and inhalation routes of exposure. It is not a dermal
sensitizer but causes corneal opacity in rabbits. Chronic studies
indicated that the liver is a target organ for toxicity. Liver toxicity
was manifested by liver weight increases and the presence of ``fatty
liver'' in rats. In dogs, increased liver weights and increases in
serum enzymes, indicative of liver toxicity, were noted. Additionally,
reproduction and developmental studies showed that fenarimol inhibited
aromatase, an enzyme involved in the conversion of androgens to
estrogens. Two acceptable rodent carcinogenicity studies showed no
evidence of significant tumor increases; therefore, fenarimol has been
classified as ``not likely to be carcinogenic to humans.''
Additionally, the toxicity database indicates no evidence of
mutagenicity or neurotoxicity.
The toxicology data for fenarimol provides no indication of
increased susceptibility, as compared to adults, of rat and rabbit
fetuses to in utero exposure in developmental studies. Developmental
kidney effects (hydronephrosis) in the rat were shown to be reversible.
The multi-generation reproduction study in rats indicates that
fenarimol causes reduced fertility in males and dystocia in females;
these effects were attributed to the inhibition of aromatase. Decreased
litter size was also noted in the study.
Non-guideline reproductive performance studies in mice, guinea
pigs, and rabbits resulted in decreased reproductive performance in
male mice, but no such effect in the guinea pig or rabbit studies. A
pubertal assay conducted in female rats resulted in decreased T4
thyroid hormone coupled with an increase in circulating thyroid
stimulating hormone (TSH) levels. A female rat uterotrophic assay
resulted in significant uterine weight increases accompanied by
increased serum follicle stimulating hormone (FSH) levels and decreased
serum T3 levels.
Specific information on the studies received and the nature of the
adverse effects caused by fenarimol 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 https://www.regulations.gov in document ``Fenarimol. Human Health Risk
Assessment for the Proposed Food Use of Fenarimol on Hops,'' pages 46
to 49 in docket ID number EPA-HQ-OPP-2007-0536.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, a toxicological point of departure (POD) is
identified as the basis for derivation of reference values for risk
assessment. The POD may be defined as the highest dose at which no
adverse effects are observed (the NOAEL) in the toxicology study
identified as appropriate for use in risk assessment. However, if a
NOAEL cannot be determined, the lowest dose at which adverse effects of
concern are identified (the LOAEL) or a benchmark dose (BMD) approach
is sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the POD to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
dietary risks by comparing aggregate food and water exposure to the
pesticide to the acute population adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The aPAD and cPAD are calculated by
dividing the POD by all applicable UFs. Aggregate short-term,
intermediate-term, and chronic-term risks are evaluated by comparing
food, water, and residential exposure to the POD to ensure that the
margin of exposure (MOE) called for by the product of all applicable
UFs is not exceeded. This latter value is referred to as the level of
concern (LOC).
[[Page 68170]]
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
greater than that 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://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for fenarimol used for

Food Use of Fenarimol on Hops,'' pages 28 to 29 in docket ID number
EPA-HQ-OPP-2007-0536.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fenarimol, EPA considered exposure under the petitioned-for
tolerances as well as all existing fenarimol tolerances in 40 CFR
180.421. EPA assessed dietary exposures from fenarimol 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
fenarimol; therefore, a quantitative acute dietary exposure assessment
is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the United States
Department of Agriculture (USDA) 1994-1996 and 1998 Continuing Surveys
of Food Intakes by Individuals (CSFII). The chronic dietary exposure
assessment for fenarimol is refined using anticipated residues (ARs)
from field trial data, processing factors, and percent crop treated
(PCT) data.
ARs based on Food and Drug Administration (FDA) monitoring data
were used for apples, bananas, cherries, grapes, and pears. Tolerance
values were assumed for foods covered by all additional tolerances. PCT
data was used for apples, cherries, grapes, and pears. Dietary Exposure
Evalution Model (DEEM) default processing factors were used for all
food commodities, except apple juice, pear juice, grape juice, and
raisins, which used factors derived from processing studies.
iii. Cancer. Based on the absence of significant tumor increases in
two adequate rodent carcinogenicity studies, EPA has classified
fenarimol as ``not likely to be carcinogenic to humans.'' Therefore, a
quantitative exposure assessment to evaluate cancer risk is
unnecessary.
iv. Anticipated residue and PCT information. Section 408(b)(2)(E)
of FFDCA authorizes EPA to use available data and information on the AR
levels of pesticide residues in food and the actual levels of pesticide
residues that have been measured in food. If EPA relies on such
information, EPA must require pursuant to FFDCA section 408(f)(1) that
data be provided 5 years after the tolerance is established, modified,
or left in effect, demonstrating that the levels in food are not above
the levels anticipated. For the present action, EPA will issue such
Data Call-Ins as are required by FFDCA section 408(b)(2)(E) and
authorized under FFDCA section 408(f)(1). Data will be required to be
submitted no later than 5 years from the date of issuance of these
tolerances.
Section 408(b)(2)(F) of FFDCA states that the Agency may use data
on the actual percent of food treated for assessing chronic dietary
risk only if:
Condition a. The data used are reliable and provide a
valid basis to show what percentage of the food derived from such crop
is likely to contain the pesticide residue.
Condition b. The exposure estimate does not underestimate
exposure for any significant subpopulation group.
Condition c. Data are available on pesticide use and food
consumption in a particular area, the exposure estimate does not
understate exposure for the population in such area.
In addition, the Agency must provide for periodic evaluation of any
estimates used. To provide for the periodic evaluation of the estimate
of PCT as required by FFDCA section 408(b)(2)(F), EPA may require
registrants to submit data on PCT.
The Agency used PCT information as follows:
Apples, 20%; cherries, 15%; grapes, 25%; and pears, 10%.
In most cases, EPA uses available data from USDA/National
Agricultural Statistics Service (NASS), proprietary market surveys, and
the National Pesticide Use Database for the chemical/crop combination
for the most recent 6 years. EPA uses an average PCT for chronic
dietary risk analysis. The average PCT figure for each existing use is
derived by combining available public and private market survey data
for that use, averaging across all observations, and rounding to the
nearest 5%, except for those situations in which the average PCT is
less than one. In those cases, 1% is used as the average PCT and 2.5%
is used as the maximum PCT. EPA uses a maximum PCT for acute dietary
risk analysis. The maximum PCT figure is the highest observed maximum
value reported within the recent 6 years of available public and
private market survey data for the existing use and rounded up to the
nearest multiple of 5%.
The Agency believes that the three conditions discussed in Unit
III.C.1.iv. have been met. With respect to Condition a, PCT estimates
are derived from Federal and private market survey data, which are
reliable and have a valid basis. The Agency is reasonably certain that
the percentage of the food treated is not likely to be an
underestimation. As to Conditions b and c, regional consumption
information and consumption information for significant subpopulations
is taken into account through EPA's computer-based model for evaluating
the exposure of significant subpopulations including several regional
groups. Use of this consumption information in EPA's risk assessment
process ensures that EPA's exposure estimate does not understate
exposure for any significant subpopulation group and allows the Agency
to be reasonably certain that no regional population is exposed to
residue levels higher than those estimated by the Agency. Other than
the data available through national food consumption surveys, EPA does
not have available reliable information on the regional consumption of
food to which fenarimol may be applied in a particular area.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for the total residues of concern, including parent
fenarimol and its organic degradates (U-1, U-2, U-6, and U-7), in
drinking water. These simulation models take into account data on the
physical, chemical, and fate/transport characteristics of fenarimol.
Further information regarding EPA drinking water models used in
pesticide exposure assessment can be found at https://www.epa.gov/oppefed1/models/water/index.htm.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated drinking water concentrations (EDWCs) of
fenarimol for surface water are estimated to be 66 parts per billion
[[Page 68171]]
(ppb) for chronic exposures. For ground water, the estimated drinking
water concentration is 19 ppb.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 66 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).
Fenarimol is currently registered for use on professionally managed
turf areas, such as stadia and golf course tees, greens, and fairways.
Short-term postapplication dermal exposure to adult golfers is
possible.
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 fenarimol to share a common mechanism of toxicity
with any other substances, and fenarimol does not appear to produce a
toxic metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that fenarimol does not
have a common mechanism of toxicity with other substances. For
information regarding EPA's efforts to determine which chemicals have a
common mechanism of toxicity and to evaluate the cumulative effects of
such chemicals, see EPA's website at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the Food Quality
Protection Act (FQPA) safety factor (SF). In applying this provision,
EPA either retains the default value of 10X, or uses a different
additional SF when reliable data available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity. The database for prenatal
developmental (in rats and rabbits) and reproductive (in rats) toxicity
is considered complete and includes special studies in addition to
conventional guideline studies. The rat developmental study showed
evidence of hydronephrosis in fetuses at dose levels equal to or
possibly lower than doses causing maternal toxicity; however, a special
study showed this effect to be reversible and therefore not considered
an adverse effect. Additionally, the decreased live born litter size
and survival indices in the rat multi-generation reproduction study are
considered to be secondary consequenies of parental effects (e.g.
dystocia and fertility), and is not an indicator of increased
susceptibility. Therefore, there is no evidence of increased
susceptibility of fetuses following in utero exposure in the rat or
rabbit developmental toxicity study or of offspring following prenatal
and postnatal exposure in the rat reproduction study, and there are no
concerns or residual uncertainties for prenatal and/or postnatal
toxicity.
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 fenarimol is complete except for
immunotoxicity testing. Recent changes to 40 CFR part 158 make
immunotoxicity testing (OPPTS Harmonized Test Guideline 870.7800)
required for pesticide registration; however, the available data for
fenarimol do not show potential for immunotoxicity. Consequently, the
EPA believes the existing data are sufficient for endpoint selection
for exposure/risk assessment scenarios and for evaluation of the
requirements under the FQPA, and an additional database UF does not
need to be applied.
ii. There is no indication that fenarimol 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 fenarimol 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 chronic dietary food exposure assessment utilized
tolerance-level residues or ARs that are based on reliable field trial
data, and factors derived from processing studies (for apple juice,
pear juice, grape juice, and raisins) or DEEM default processing
factors. For several currently registered commodities, the chronic
assessment also utilized PCT data that have a valid basis and are
considered to be reliable. EPA made conservative (protective)
assumptions in the ground and surface water modeling used to assess
exposure to fenarimol in drinking water. EPA made similarly
conservative assumptions to assess postapplication exposures. These
assessments will not underestimate the exposure and risks posed by
fenarimol.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic pesticide exposures are
safe by comparing aggregate exposure estimates to the aPAD and cPAD.
The aPAD and cPAD represent the highest safe exposures, taking into
account all appropriate SFs. EPA calculates the aPAD and cPAD by
dividing the POD by all applicable UFs. For linear cancer risks, EPA
calculates the probability of additional cancer cases given the
estimated aggregate exposure. Short-term, intermediate-term, and
chronic-term risks are evaluated by comparing the estimated aggregate
food, water, and residential exposure to the POD to ensure that the MOE
called for by the product of all applicable UFs is not exceeded.
1. Acute risk. An acute aggregate risk assessment takes into
account exposure estimates from acute 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,
fenarimol 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
fenarimol from food and water will utilize 76% of the cPAD for infants
less than 1-year 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
fenarimol 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). Fenarimol is
currently registered for use on professionally managed turf, including
stadia and golf
[[Page 68172]]
course tees, greens, and fairways, which could result in short-term
postapplication dermal exposure to golfers. The Agency has determined
that it is appropriate to aggregate chronic exposure through food and
water with short-term residential exposures to fenarimol.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures aggregated result in aggregate MOEs of 8,800
for adults 20-49 years old. EPA has determined that this assessment
adequately estimates the risk for youth golfers as well. As the
aggregate MOE is greater than 1,000 (the LOC), short-term aggregate
exposure to fenarimol is not of concern to EPA.
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). Fenarimol is not registered for any use patterns that would
result in intermediate-term residential exposure. Therefore, the
intermediate-term aggregate risk is the sum of the risk from exposure
to fenarimol through food and water, which has already been addressed,
and will not be greater than the chronic aggregate risk.
5. Aggregate cancer risk for U.S. population. As discussed in Unit
III.C.1.iii., EPA has classified fenarimol as ``not likely to be
carcinogenic to humans,'' and it 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 fenarimol residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology, gas chromatography (GC) with an
electrolytic conductivity detector (ECD), is available to enforce the
tolerance expression, and is published in the Pesticide Analytical
Manual (PAM) Vol. II (Method R039).
B. International Residue Limits
Residue definitions are harmonized between the United States,
Codex, and Mexico. In order to harmonize with a Codex MRL of 0.3 ppm
for apples, EPA is increasing the tolerance for residues of apples from
0.1 ppm to 0.3 ppm. Additionally, a Codex MRL exists on hop dried cones
at 5.0 ppm. The Agency is establishing a tolerance on hop, dried cones
at 5.0 ppm to harmonize MRLs between the United States and Codex for
this commodity.
C. Response to Comments
EPA received one comment to the proposed rule of June 6, 2007,
which made a general objection to the presence of any pesticide
residues on crops and stated that EPA should set no pesticide tolerance
greater than zero. The Agency understands the commenter's concerns and
recognizes that some individuals believe that pesticides should be
banned completely. However, the existing legal framework provided by
section 408 of the FFDCA states that tolerances greater than zero may
be set when it has been demonstrated that the pesticide meets the
safety standard imposed by that statute. This citizen's comment appears
to be directed at the underlying statute and not EPA's implementation
of it; the citizen has made no contention that EPA has acted in
violation of the statutory framework.
D. Revisions to Petitioned-For Tolerances
Based upon review of the data supporting the IR-4 petition, EPA
revised the proposed tolerance for hop, dried cones from 1.0 ppm to 1.2
ppm. EPA revised the tolerance level based on analysis of the residue
field trial data using the Agency's Tolerance Spreadsheet in accordance
with the Agency's ``Guidance for Setting Pesticide Tolerances Based on
Field Trial Data.'' However, it was discovered that a Codex MRL exists
on hops, dried cones at 5.0 ppm. As a result, EPA has increased the
hop, dried cones tolerance from 1.2 ppm to 5.0 ppm to harmonize with
Codex. The potentially greater exposure under this increased tolerance
value was included in EPA's fenarimol risk assessment.
V. Conclusion
Therefore, a tolerance is established for residues of fenarimol,
alpha-(2-chlorophenyl)-alpha-(4-chlorophenyl)-5-pyrimidinemethanol, in
or on hop, dried cones at 5.0 ppm. Additionally, the established
tolerance of fenarimol in or on apple is increased from 0.1 ppm to 0.3
ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes tolerances under section 408(d) and
408(e) of FFDCA following an agency initiated proposal. 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 section 408(d) of FFDCA, such as the tolerance in
this final rule on hops, dried cones, 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 to this tolerance. The tolerance on
apples, however, was initiated by an EPA proposal and thus the RFA is
applicable. Pursuant to the RFA, the Agency hereby certifies that the
apple tolerance will not have significant negative economic impact on a
substantial number of small entities. Establishing a pesticide
tolerance or an exemption from the requirement of a pesticide tolerance
is, in effect, the removal of a regulatory restriction on pesticide
residues in food and thus such an action will not have any negative
economic impact on any entities, including small entities.
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 section 408(n)(4) of FFDCA. 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,
[[Page 68173]]
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) (Public Law
104-4).
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), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. 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 this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
