Federal Register / Vol. 85, No. 46 / Monday, March 9, 2020 / Rules and Regulations
of FFDCA section 408(n)(4). As such,
EPA 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, EPA 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 (2 U.S.C. 1501
et seq.).
This action does not involve any
technical standards that would require
EPA’s consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act (15
U.S.C. 272 note).
V. 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

II. Summary of Petitioned-For
Tolerance
In the Federal Register of May 9, 2019
(84 FR 20320) (FRL–9992–36), 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 8E8727) by IR–4, Rutgers,
The State University of New Jersey, 500
College Road East, Suite 201W,
Princeton, NJ 08540. The petition
requested that 40 CFR 180.605 be
amended by establishing a tolerance for
residues of the herbicide penoxsulam,
including its metabolites and
degradates, in or on artichoke, globe at
0.01 parts per million (ppm). That
document referenced a summary of the
petition prepared by Dow AgroSciences,
the registrant, which is available in the
docket, https://www.regulations.gov.
Comments were received on the notice
of filing. EPA’s response to these
comments is discussed in Unit IV.C.
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
VerDate Sep<11>2014
16:34 Mar 06, 2020
Jkt 250001
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 penoxsulam
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with penoxsulam 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 kidney was the major target organ
for penoxsulam in the rat and dog
following subchronic and chronic
dietary exposure. There are no
mechanistic studies characterizing the
mode of action for renal toxicity of
penoxsulam or other triazolopyrimidine
herbicides, but the presence of crystals
in the urinary tract and lack of tissue
bioaccumulation suggest that cellular
inflammation and damage may occur
secondary to their presence.
Hyperplasia (rat and dog) and
inflammation (rat) of the renal pelvic
epithelium were observed by week 4 in
dietary dose range-finding studies. The
dog was the more sensitive species in
studies of all durations. The rat, but not
the dog, showed progression of the
severity of kidney toxicity with
prolonged exposure. In dogs, renal
toxicity in the subchronic and chronic
studies occurred at comparable dose
levels and measurable effects on renal
function were not observed. In the rat,
effects on renal function (increased
blood urea nitrogen in both sexes,
urinary bladder mucosal hyperplasia,
and increased severity of chronic
glomerulonephropathy in males) were
observed only following chronic
exposure, although the doses at which
kidney toxicity occurred were
comparable to doses tested in the
subchronic study. A consistent pattern
that identified a greater sensitivity of
either sex was not observed.

Frm 00075
Fmt 4700
Sfmt 4700
13549
Other effects in the rat included
decreased red blood cell parameters and
decreased body weight and/or weight
gain. Liver effects were observed at the
higher dose levels in the dog 4-week
feeding study but not in other studies in
the database. The findings of liver and/
or kidney effects are consistent with
effects observed for other
triazolopyrimidine herbicides.
No effects of toxicological significance
were observed in the mouse.
Penoxsulam showed no evidence of
neurotoxicity or immunotoxicity in the
rodent, and no effects were seen in rats
following dermal exposure. The Agency
waived the requirement for inhalation
data based on high inhalation margins
of exposure using an oral endpoint, lack
of observed irritation effects, and low
vapor pressure.
There was no evidence of increased
pre- and/or post-natal susceptibility. No
developmental effects were observed in
the rat or rabbit. Maternal effects in the
rat included decreased body weight gain
and food consumption and increased
kidney weights. In the rabbit, maternal
effects included mortality, clinical signs
of toxicity, and decreased body weight
gain and food consumption. In the rat 2generation reproductive toxicity study,
delayed preputial separation and
lactation body weights were observed in
F1 offspring at a dose that caused
kidney lesions in parental females.
Although there is evidence of an
increased incidence of mononuclear cell
leukemia (MNCL) in Fisher 344 rats
from exposure to penoxsulam, EPA has
concluded that a quantitative
assessment of cancer is not necessary
and that the chronic reference dose
(cRfD) is considered protective of
possible cancer effects.
Specific information on the studies
received and the nature of the adverse
effects caused by penoxsulam 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 the document
titled ‘‘Penoxsulam: Human Health Risk
Assessment for the Proposed Use on
Globe Artichoke’’ (Penoxsulam HHRA)
on pages 32–37 in docket ID number
EPA–HQ–OPP–2019–0061. For further
discussion of the Agency’s rationale for
its cancer conclusion, see page 16 of the
Penoxsulam HHRA.
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
E:\FR\FM\09MRR1.SGM
09MRR1
13550
Federal Register / Vol. 85, No. 46 / Monday, March 9, 2020 / Rules and Regulations
jbell on DSKJLSW7X2PROD with RULES
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-pesticide.
A summary of the toxicological
endpoints for penoxsulam used for
human risk assessment is discussed in
Unit III.B of the final rule published in
the Federal Register of March 2, 2016
(81 FR 10771) (FRL–9940–36).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to penoxsulam, EPA
considered exposure under the
petitioned-for tolerance as well as all
existing penoxsulam tolerances in 40
CFR 180.605. EPA assessed dietary
exposures from penoxsulam 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 penoxsulam;
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’s
(USDA’s) 2003–2008 National Health
and Nutrition Examination Survey,
What We Eat in America, (NHANES/
WWEIA). As to residue levels in food,
the chronic dietary exposure assessment
VerDate Sep<11>2014
16:34 Mar 06, 2020
Jkt 250001
was unrefined and used tolerance-level
residues and 100 percent crop treated
(PCT).
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that the cRfD is protective of
potential cancer risk from exposure to
penoxsulam.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue or PCT information
in the dietary assessment for
penoxsulam. Tolerance-level residues
and 100 PCT were assumed for all food
commodities as well as contribution to
the 5–OH-penoxsulam metabolite in
fish.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for penoxsulam in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
penoxsulam. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www2.epa.gov/
pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide.
Penoxsulam is registered for control
of aquatic weeds. For that use pattern,
the maximum application rate is 150
parts per billion (ppb) in the water
column. For the chronic dietary risk
assessment, the water concentration
value of 150 ppb was used to assess the
contribution to drinking water. This
value is likely to be an overestimate of
actual residues in 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).
Penoxsulam is currently registered for
the following uses that could result in
residential exposures: Residential and
commercial turf (lawns and golf
courses) and aquatic use sites. EPA
assessed residential exposure using the
following assumptions: For handlers, it
is assumed that residential use will
result in short-term (1 to 30 days)
dermal and inhalation exposures.
Residential post-application exposure is
also assumed to be short-term (1 to 30
days) in duration, resulting from the
following exposure scenarios:
Physical activities on turf: Adults
(dermal) and children 1 to 2 years old
(dermal and incidental oral);
Mowing turf: Adults (dermal) and
children 11 to <16 years old (dermal);
PO 00000
Frm 00076
Fmt 4700
Sfmt 4700
Exposure to golf courses during
golfing: Adults (dermal), children 11 to
<16 years old (dermal), and children 6
to <11 years old (dermal); and
Exposure during aquatic activities
(e.g. swimming): Adults (dermal,
inhalation, ingestion) and children 3 to
<6 years old (dermal, inhalation,
ingestion).
Due to the lack of a dermal endpoint,
EPA did not quantify exposure and risk
estimates from dermal exposure
scenarios. EPA did not combine
exposure resulting from adult handler
and post-application exposure resulting
from treated gardens, lawns, golfing,
and/or aquatic areas in residential
settings because of the conservative
assumptions and inputs within each
estimated exposure scenario. The
Agency believes that combining
exposures resulting from handler and
post-application activities would result
in an overestimate of adult exposure.
EPA selected the most conservative
adult residential scenario (adult handler
inhalation exposure from backpack
sprayer applications to lawns/turf) as
the contributing source of residential
exposure to be combined with the
dietary exposure for the aggregate
assessment. The exposure for the
aggregate assessment for children 3 to
<6 years old is based on postapplication combined inhalation and
ingestion exposures during aquatic
activities. The oral exposure for the
aggregate assessment for children 1 to
<2 years old is based on postapplication hand-to-mouth exposures
from applications to lawns/turf. To
include exposure from object-to-mouth
and soil ingestion in addition to handto-mouth would overestimate the
potential for oral exposure. Further
information regarding EPA standard
assumptions and generic inputs for
residential exposures may be found at
https://www2.epa.gov/pesticide-scienceand-assessing-pesticide-risks/standardoperating-procedures-residentialpesticide.
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.’’
Unlike other pesticides for which EPA
has followed a cumulative risk approach
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
penoxsulam and any other substances
E:\FR\FM\09MRR1.SGM
09MRR1
Federal Register / Vol. 85, No. 46 / Monday, March 9, 2020 / Rules and Regulations
jbell on DSKJLSW7X2PROD with RULES
and penoxsulam does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this action, therefore, EPA has not
assumed that penoxsulam has 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://
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
FQPA Safety Factor (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.
No evidence of quantitative or
qualitative increased susceptibility, as
compared to adults, of rat fetuses to in
utero or postnatal exposure was
observed in developmental toxicity
studies in rats or rabbits or a
reproduction study in rats.
Developmental toxicity was not
observed in the rat or rabbit up to doses
resulting in maternal toxicity. In the rat
reproductive toxicity study, slightly
increased time to preputial separation in
F1 males and decreased pup weight gain
were observed in the presence of
parental toxicity (kidney lesions in
females).
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
penoxsulam is complete.
ii. There is no indication that
penoxsulam is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional uncertainty factors to account
for neurotoxicity.
iii. There is no evidence that
penoxsulam results in increased
VerDate Sep<11>2014
16:34 Mar 06, 2020
Jkt 250001
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
by using the high-end EDWC of 150 ppb
from the aquatic weed use pattern to
assess exposure to penoxsulam in
drinking water. EPA used similarly
conservative assumptions to assess postapplication exposure of children as well
as incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by penoxsulam.
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, penoxsulam 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 penoxsulam
from food and water will utilize 5.6% of
the cPAD for all 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
penoxsulam 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). Penoxsulam 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
PO 00000
Frm 00077
Fmt 4700
Sfmt 4700
13551
and water with short-term residential
exposures to penoxsulam.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures result in aggregate
MOEs of 5,500 for adults, 1,700 for
children 1 to 2 years old, and 4,500 for
children 3 to 5 years old. Because EPA’s
level of concern for penoxsulam is a
MOE of 100 or below, these MOEs are
not of concern.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
An intermediate-term adverse effect
was identified; however, penoxsulam 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
penoxsulam.
5. Aggregate cancer risk for U.S.
population. As discussed in Unit III.A.,
EPA has determined that an RfD
approach based on the chronic point of
departure is appropriate for evaluating
cancer risk. As there are not chronic
aggregate risks of concern, there are no
cancer aggregate risk concerns.
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 penoxsulam
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies
using high performance liquid
chromatography with tandem mass
spectroscopy (HPLC–MS/MS) are
available to enforce the tolerance
expression. These methods may be
requested from: Chief, Analytical
Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755–5350; telephone
number: (410) 305–2905; email address:

B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
The Codex has not established a MRL
for penoxsulam on globe artichoke.
C. Response to Comments
Two comments were received in
response to the notice of filing. One was
against the Agency granting the use of
penoxsulam and one was against the use
of pesticides in general. Although the
Agency recognizes that some
individuals believe that pesticides
should be banned on agricultural crops,
the existing legal framework provided
by section 408 of the Federal Food, Drug
and Cosmetic Act (FFDCA) authorizes
EPA to establish tolerances when it
determines that the tolerance is safe.
Upon consideration of the validity,
completeness, and reliability of the
available data as well as other factors
the FFDCA requires EPA to consider,
EPA has determined that these
penoxsulam tolerances are safe. The
commenters have provided no
information to support an Agency
conclusion that penoxsulam is not safe.

V. Conclusion
Therefore, tolerances are established
for residues of penoxsulam, including
its metabolites and degradates, in or on
artichoke, globe at 0.01 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
VerDate Sep<11>2014
16:34 Mar 06, 2020
Jkt 250001
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), nor is it considered a
regulatory action under Executive Order
13771, entitled ‘‘Reducing Regulations
and Controlling Regulatory Costs’’ (82
FR 9339, February 3, 2017). 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
PO 00000
Frm 00078
Fmt 4700
Sfmt 4700
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).

II. Summary of Petitioned-For Tolerance
In the Federal Register of May 9, 2019 (84 FR 20320) (FRL-9992-36),
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 8E8727)
by IR-4, Rutgers, The State University of New Jersey, 500 College Road
East, Suite 201W, Princeton, NJ 08540. The petition requested that 40
CFR 180.605 be amended by establishing a tolerance for residues of the
herbicide penoxsulam, including its metabolites and degradates, in or
on artichoke, globe at 0.01 parts per million (ppm). That document
referenced a summary of the petition prepared by Dow AgroSciences, the
registrant, which is available in the docket, https://www.regulations.gov. Comments were received on the notice of filing.
EPA's response to these comments is discussed in Unit IV.C.
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 penoxsulam including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with penoxsulam 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 kidney was the major target organ for penoxsulam in the rat and
dog following subchronic and chronic dietary exposure. There are no
mechanistic studies characterizing the mode of action for renal
toxicity of penoxsulam or other triazolopyrimidine herbicides, but the
presence of crystals in the urinary tract and lack of tissue
bioaccumulation suggest that cellular inflammation and damage may occur
secondary to their presence. Hyperplasia (rat and dog) and inflammation
(rat) of the renal pelvic epithelium were observed by week 4 in dietary
dose range-finding studies. The dog was the more sensitive species in
studies of all durations. The rat, but not the dog, showed progression
of the severity of kidney toxicity with prolonged exposure. In dogs,
renal toxicity in the subchronic and chronic studies occurred at
comparable dose levels and measurable effects on renal function were
not observed. In the rat, effects on renal function (increased blood
urea nitrogen in both sexes, urinary bladder mucosal hyperplasia, and
increased severity of chronic glomerulonephropathy in males) were
observed only following chronic exposure, although the doses at which
kidney toxicity occurred were comparable to doses tested in the
subchronic study. A consistent pattern that identified a greater
sensitivity of either sex was not observed.
Other effects in the rat included decreased red blood cell
parameters and decreased body weight and/or weight gain. Liver effects
were observed at the higher dose levels in the dog 4-week feeding study
but not in other studies in the database. The findings of liver and/or
kidney effects are consistent with effects observed for other
triazolopyrimidine herbicides.
No effects of toxicological significance were observed in the
mouse. Penoxsulam showed no evidence of neurotoxicity or immunotoxicity
in the rodent, and no effects were seen in rats following dermal
exposure. The Agency waived the requirement for inhalation data based
on high inhalation margins of exposure using an oral endpoint, lack of
observed irritation effects, and low vapor pressure.
There was no evidence of increased pre- and/or post-natal
susceptibility. No developmental effects were observed in the rat or
rabbit. Maternal effects in the rat included decreased body weight gain
and food consumption and increased kidney weights. In the rabbit,
maternal effects included mortality, clinical signs of toxicity, and
decreased body weight gain and food consumption. In the rat 2-
generation reproductive toxicity study, delayed preputial separation
and lactation body weights were observed in F1 offspring at a dose that
caused kidney lesions in parental females.
Although there is evidence of an increased incidence of mononuclear
cell leukemia (MNCL) in Fisher 344 rats from exposure to penoxsulam,
EPA has concluded that a quantitative assessment of cancer is not
necessary and that the chronic reference dose (cRfD) is considered
protective of possible cancer effects.
Specific information on the studies received and the nature of the
adverse effects caused by penoxsulam 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 the document titled ``Penoxsulam: Human Health
Risk Assessment for the Proposed Use on Globe Artichoke'' (Penoxsulam
HHRA) on pages 32-37 in docket ID number EPA-HQ-OPP-2019-0061. For
further discussion of the Agency's rationale for its cancer conclusion,
see page 16 of the Penoxsulam HHRA.
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
[[Page 13550]]
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-and-assessing-pesticide-risks/assessing-human-health-risk-pesticide.
A summary of the toxicological endpoints for penoxsulam used for
human risk assessment is discussed in Unit III.B of the final rule
published in the Federal Register of March 2, 2016 (81 FR 10771) (FRL-
9940-36).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to penoxsulam, EPA considered exposure under the petitioned-
for tolerance as well as all existing penoxsulam tolerances in 40 CFR
180.605. EPA assessed dietary exposures from penoxsulam 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
penoxsulam; 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's (USDA's) 2003-2008 National Health and
Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA).
As to residue levels in food, the chronic dietary exposure assessment
was unrefined and used tolerance-level residues and 100 percent crop
treated (PCT).
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that the cRfD is protective of potential cancer risk from
exposure to penoxsulam.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue or PCT information in the dietary assessment for
penoxsulam. Tolerance-level residues and 100 PCT were assumed for all
food commodities as well as contribution to the 5-OH-penoxsulam
metabolite in fish.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for penoxsulam in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of penoxsulam. 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.
Penoxsulam is registered for control of aquatic weeds. For that use
pattern, the maximum application rate is 150 parts per billion (ppb) in
the water column. For the chronic dietary risk assessment, the water
concentration value of 150 ppb was used to assess the contribution to
drinking water. This value is likely to be an overestimate of actual
residues in 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).
Penoxsulam is currently registered for the following uses that
could result in residential exposures: Residential and commercial turf
(lawns and golf courses) and aquatic use sites. EPA assessed
residential exposure using the following assumptions: For handlers, it
is assumed that residential use will result in short-term (1 to 30
days) dermal and inhalation exposures. Residential post-application
exposure is also assumed to be short-term (1 to 30 days) in duration,
resulting from the following exposure scenarios:
Physical activities on turf: Adults (dermal) and children 1 to 2
years old (dermal and incidental oral);
Mowing turf: Adults (dermal) and children 11 to <16 years old
(dermal);
Exposure to golf courses during golfing: Adults (dermal), children
11 to <16 years old (dermal), and children 6 to <11 years old (dermal);
and
Exposure during aquatic activities (e.g. swimming): Adults (dermal,
inhalation, ingestion) and children 3 to <6 years old (dermal,
inhalation, ingestion).
Due to the lack of a dermal endpoint, EPA did not quantify exposure
and risk estimates from dermal exposure scenarios. EPA did not combine
exposure resulting from adult handler and post-application exposure
resulting from treated gardens, lawns, golfing, and/or aquatic areas in
residential settings because of the conservative assumptions and inputs
within each estimated exposure scenario. The Agency believes that
combining exposures resulting from handler and post-application
activities would result in an overestimate of adult exposure. EPA
selected the most conservative adult residential scenario (adult
handler inhalation exposure from backpack sprayer applications to
lawns/turf) as the contributing source of residential exposure to be
combined with the dietary exposure for the aggregate assessment. The
exposure for the aggregate assessment for children 3 to <6 years old is
based on post-application combined inhalation and ingestion exposures
during aquatic activities. The oral exposure for the aggregate
assessment for children 1 to <2 years old is based on post-application
hand-to-mouth exposures from applications to lawns/turf. To include
exposure from object-to-mouth and soil ingestion in addition to hand-
to-mouth would overestimate the potential for oral exposure. 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.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to penoxsulam and any other
substances
[[Page 13551]]
and penoxsulam does not appear to produce a toxic metabolite produced
by other substances. For the purposes of this action, therefore, EPA
has not assumed that penoxsulam has 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://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 FQPA Safety
Factor (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. No evidence of quantitative
or qualitative increased susceptibility, as compared to adults, of rat
fetuses to in utero or postnatal exposure was observed in developmental
toxicity studies in rats or rabbits or a reproduction study in rats.
Developmental toxicity was not observed in the rat or rabbit up to
doses resulting in maternal toxicity. In the rat reproductive toxicity
study, slightly increased time to preputial separation in F1 males and
decreased pup weight gain were observed in the presence of parental
toxicity (kidney lesions in females).
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 penoxsulam is complete.
ii. There is no indication that penoxsulam is a neurotoxic chemical
and there is no need for a developmental neurotoxicity study or
additional uncertainty factors to account for neurotoxicity.
iii. There is no evidence that penoxsulam 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 by using the high-end EDWC of 150 ppb from the
aquatic weed use pattern to assess exposure to penoxsulam 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 penoxsulam.
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,
penoxsulam 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
penoxsulam from food and water will utilize 5.6% of the cPAD for all
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
penoxsulam 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). Penoxsulam 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 penoxsulam.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 5,500 for adults,
1,700 for children 1 to 2 years old, and 4,500 for children 3 to 5
years old. Because EPA's level of concern for penoxsulam is a MOE of
100 or below, these MOEs are not of concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level).
An intermediate-term adverse effect was identified; however,
penoxsulam 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
penoxsulam.
5. Aggregate cancer risk for U.S. population. As discussed in Unit
III.A., EPA has determined that an RfD approach based on the chronic
point of departure is appropriate for evaluating cancer risk. As there
are not chronic aggregate risks of concern, there are no cancer
aggregate risk concerns.
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 penoxsulam residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies using high performance liquid
chromatography with tandem mass spectroscopy (HPLC-MS/MS) are available
to enforce the tolerance expression. These methods may be requested
from: Chief, Analytical Chemistry Branch, Environmental Science Center,
701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-
2905; email address: [email protected].

B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for penoxsulam on globe
artichoke.
C. Response to Comments
Two comments were received in response to the notice of filing. One
was against the Agency granting the use of penoxsulam and one was
against the use of pesticides in general. Although the Agency
recognizes that some individuals believe that pesticides should be
banned on agricultural crops, the existing legal framework provided by
section 408 of the Federal Food, Drug and Cosmetic Act (FFDCA)
authorizes EPA to establish tolerances when it determines that the
tolerance is safe. Upon consideration of the validity, completeness,
and reliability of the available data as well as other factors the
FFDCA requires EPA to consider, EPA has determined that these
penoxsulam tolerances are safe. The commenters have provided no
information to support an Agency conclusion that penoxsulam is not
safe.
V. Conclusion
Therefore, tolerances are established for residues of penoxsulam,
including its metabolites and degradates, in or on artichoke, globe at
0.01 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), nor is it considered a
regulatory action under Executive Order 13771, entitled ``Reducing
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3,
2017). 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).
