II. Petition for Tolerance
In the Federal Register of May 9, 2007
(72 FR 26375) (FRL–8128–1), 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 7E7195) by IR-4,
500 College Road East, Suite 201 W,
Princeton, NJ 08540. The petition
requested that 40 CFR 180.607 be
amended by establishing tolerances for
combined residues of the insecticide
spiromesifen, (2-oxo-3-(2,4,6trimethylphenyl)-1-oxaspiro[4.4]non-3en-4-yl 3,3-dimethylbutanoate) and its
enol metabolite (4-hydroxy-3-(2,4,6trimethylphenyl)-1-oxaspiro[4.4]non-3en-2-one), in or on bean, edible, podded
at 1.4 ppm; bean, succulent at 0.10 ppm;
bean, dry at 0.02 ppm; cowpea, forage

0.30 ppm; and milk at 0.01 ppm. This
notice referenced a summary of the
petition prepared by Bayer Crop
Science, 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.
Based upon review of the data
supporting the petition, EPA has revised
tolerance expressions for bean, edible,
podded; cowpea, forage; milk, whole;
milk, fat; in meat of cattle, goats, horses,
and sheep; in meat, byproducts, of
cattle, goats, horses, and sheep; and in
fat of cattle, goats, horses, and sheep. A
tolerance for cowpea, hay was also
included. The reason for these changes
is explained 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....’’ These provisions
were added to FFDCA by the Food
Quality Protection Act (FQPA) of 1996.
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 the petitioned-for
tolerances for combined residues of
spiromesifen on bean, dry at 0.02 ppm;
bean, succulent at 0.10 ppm; bean,
edible podded at 0.80 ppm; cowpea,
forage at 30 ppm; cowpea, hay at 86
ppm; cattle, fat at 0.10 ppm; cattle, meat
at 0.02 ppm; cattle, meat byproducts at
0.15 ppm; goat, fat at 0.10 ppm; goat,

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.
Spiromesifen shows low acute
toxicity via the oral, dermal and
inhalation routes of exposure. It was
neither an eye nor dermal irritant, but
showed moderate potential as a contact
sensitizer in a Magnusson and Kligman
maximization assay. Acute dietaryexposure limits for all populations,
including infants and children, were not
necessary because an endpoint of
concern attributable to a single exposure
(dose) was not identified from the oral
toxicity studies. In addition, there are
no developmental concerns based on rat
and/or rabbit developmental toxicity
studies. The rat two-generation
reproduction study was selected for
chronic dietary, as well as long-term
dermal- and inhalation-exposure risk
assessments.
In the 2-generation reproduction
study in rat the following effects were
noted at the lowest observed adverse
effect level (LOAEL): Significantly
decreased spleen weight (absolute and
relative in parental females and F1
males) and significantly decreased
growing ovarian follicles in females.
Spiromesifen shows no significant
developmental or reproductive effects,
is not likely to be carcinogenic based on
bioassays in rat and mouse, and lacks in
vivo and in vitro mutagenic effects.
Spiromesifen is not a neurotoxic
chemical based on results of acute and
subchronic neurotoxicity studies.
Specific information on the studies
received and the nature of the adverse
effects caused by spiromesifen as well
as the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found in the
document entitled ‘‘Spiromesifen:
Human Health Risk Assessment for a
Section 3 Registration on Beans;’’ pages
44-52 at www.regulations.gov. The
referenced document is available in
docket EPA–HQ–OPP–2007–0331.

Jkt 214001
B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, the toxicological level of concern
(LOC) is derived from 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) is sometimes
used for risk assessment. Uncertainty/
safety factors (UFs) are used in
conjunction with the LOC 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 risks by comparing
aggregate 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 LOC by all
applicable UFs. Short-, intermediate-,
and long-term risks are evaluated by
comparing aggregate exposure to the
LOC to ensure that the margin of
exposure (MOE) called for by the
product of all applicable UFs is not
exceeded.
For non-threshold risks, the Agency
assumes that any amount of exposure
will lead to some degree of risk and
estimates risk in terms of the probability
of occurrence of additional adverse
cases. Generally, cancer risks are
considered non-threshold. 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/fedrgstr/EPA-PEST/1997/
November/Day-26/p30948.htm.
A summary of the toxicological
endpoints for spiromesifen used for
human risk assessment can be found at
https://www.regulations.gov in the
document entitled ‘‘Spiromesifen:
Human Health Risk Assessment for a
Section 3 Registration on Beans;’’ pages
18-19; docket ID number EPA–HQ–
OPP–2007–0331.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to spiromesifen, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing spiromesifen tolerances in (40
CFR 180.607). EPA assessed dietary
exposures from spiromesifen in food as
follows:
PO 00000
Frm 00068
Fmt 4700
Sfmt 4700
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 spiromesifen;
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 USDA 1994–1996, and 1998
CSFII. As to residue levels in food, EPA
assumed tolerance-level residues for all
commodities with existing and
proposed tolerances except for the leafygreen and leafy-Brassica vegetable
subgroups (4A and 5B). An additional
metabolite, BSN 2060-4-hydroxymethyl,
was observed in the metabolism studies
of lettuce only. Since this metabolite’s
toxicity is expected to be comparable to
the parent compound, it was included
in the risk assessment for leafy crops
(subgroups 4A and 5B), but not in the
tolerance expression. To account for this
additional toxicity exposure, the
recommended tolerance level was
multiplied by a correction factor of 1.3x.
For all commodities, 100%CT as well as
DEEMTM Version 7.81 default
processing factors were used.
iii. Cancer. Spiromesifen has been
classified as ‘‘not likely to be
carcinogenic to humans.’’ Therefore, a
cancer dietary risk assessment was not
performed.
2. Dietary exposure from drinking
water.The Agency lacks sufficient
monitoring data to complete a
comprehensive dietary exposure
analysis and risk assessment for
spiromesifen in drinking water. Because
the Agency does not have
comprehensive monitoring data,
drinking water concentration estimates
are made by reliance on simulation or
modeling taking into account data on
the environmental fate characteristics of
spiromesifen. 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.
Parent spiromesifen is not likely to
persist in the environment as it readily
undergoes both biotic and abiotic
degradation; however, its primary
degradate BSN2060 is expected to
persist. While parent spiromensifen
strongly sorbs to sediment and is not
likely to be mobile, its enol degradate
does not sorb to sediment and is
expected to leach into groundwater.
Spiromesifen has limited solubility in
water and is some cases has been

12MRR1
jlentini on PROD1PC65 with RULES
Federal Register / Vol. 73, No. 49 / Wednesday, March 12, 2008 / Rules and Regulations
reported to have a practical solubility
limit of 40 to 50 µg/L. The pesticide
degrades primarily through aerobic soil
metabolism and hydrolysis; however, in
clear shallow water it will readily
undergo photolysis. Field studies
indicate that spiromesifen readily
dissipates with dissipation half lives
ranging from 2 to 10 days. The
compound is not likely to
bioconcentrate appreciably given its
relatively rapid degradation and
depuration.
Spiromesifen and BSN 2060-enol are
the predominant residues in drinking
water. BSN 2060-enol may account for
75% of the total acute exposure and for
over 90% for chronic exposure.
Estimated drinking water concentrations
(EDWCs) were generated for the total
toxic residue which includes
spiromesifen, the -enol and -carboxy
metabolites, and unextracted material.
The highest estimated surface water
concentrations occurred with the NC
sweet potato scenario.
Based on the Pesticide Root Zone
Model /Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening
Concentration in Ground Water (SCIGROW) models, the estimated
environmental concentration (EEC) of
spiromesifen for chronic exposure is
estimated to be 11 parts per billion
(ppb) for surface water. The EEC for
chronic exposure is estimated to be 28
ppb for ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 28 ppb was
used to access 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).
Spiromesifen is not registered for use
on any sites that would result in
residential exposure.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
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

17:40 Mar 11, 2008

13139
mechanism of toxicity finding as to
spiromesifen and any other substances
and spiromesifen does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that spiromesifen 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 Web site at https://
www.epa.gov/pesticides/cumulative.
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%CT and
tolerance-level residues or higher.
Conservative ground and surface water
modeling estimates were used.
Residential exposure is not expected as
spiromesifen will be registered for
agricultural and greenhouse/ornamental
uses only. These assessments will not
underestimate the exposure and risks
posed by spiromesifen.
D. Safety Factor for Infants and
Children
E. Aggregate Risks and Determination of
Safety
Safety is assessed for acute and
chronic risks by comparing aggregate
exposure to the pesticide to the aPAD
and cPAD. The aPAD and cPAD are
calculated by dividing the LOC by all
applicable UFs. For linear cancer risks,
EPA calculates the probability of
additional cancer cases given aggregate
exposure. Short-, intermediate-, and
long-term risks are evaluated by
comparing aggregate exposure to the
LOC to ensure that the MOE called for
by the product of all applicable UFs is
not exceeded.
1. Acute risk. No such effects were
identified in the toxicological studies
for spiromesifen; therefore, acute
exposure is not expected.
2. Chronic risk.Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that exposure to spiromesifen from food
and water will utilize 42% of the cPAD
for the population group children 3-5
years old (the greatest exposure). There
are no residential uses for spiromesifen
that result in chronic residential
exposure to spiromesifen.
3. Short and intermediate-term risk.
Short and Intermediate-term aggregate
exposure takes into account residential
exposure plus chronic exposure to food
and water (considered to be a
background exposure level).
Spiromesifen is not registered for use
on any sites that would result in
residential exposure. Therefore, the
aggregate risk is the sum of the risk from
food and water.
4. Aggregate cancer risk for U.S.
population. Spiromesifen has been
classified as ‘‘not likely to be
carcinogenic to humans.’’ Spiromesifen
is not expected to pose a cancer risk.
5. 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 spiromesifen
residues.
1. In general. Section 408 of FFDCA
provides that EPA shall apply an
additional (‘‘10X’’) tenfold 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. In applying this
provision, EPA either retains the default
value of 10X when reliable data do not
support the choice of a different factor,
or, if reliable data are available, EPA
uses a different additional FQPA safety
factor value based on the use of
traditional UFs and/or special FQPA
safety factors, as appropriate.
2. Prenatal and postnatal sensitivity.
There is no evidence of increased
susceptibility of rats or rabbits to in
utero and/or postnatal exposure to
spiromesifen. In the prenatal
developmental toxicity studies in rats
and rabbits and in the two-generation
reproduction study in rats,
developmental toxicity to the offspring
occurred at equivalent or higher doses
than parental toxicity.
3. Conclusion. EPA has determined
that reliable data show that it would be
safe for infants and children to reduce
the FQPA safety factor to 1X. That
decision is based on the following
findings:
i. The toxicity database for
spiromesifen is complete.
ii. There is no indication that
spiromesifen 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
spiromesifen results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or

IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology,
high performance liquid
chromatography/mass spectroscopy
(HPLC/MS/MS)/ Method 00631/M001,
is available to enforce the tolerance
expression. The method may be
requested from: Chief, Analytical
Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755–5350; telephone
number: (410) 305–2905; e-mail address:
residuemethods@epa.gov.
B. International Residue Limits
No Codex, Canadian, or Mexican
MRLs have been established for residues
of spiromesifen and its metabolites.
jlentini on PROD1PC65 with RULES
C. Explanation of Tolerance Revisions
1. Bean, edible podded and cowpea,
forage. The tolerances were revised
based on analysis with the Agency’s
tolerance spreadsheet in accordance
with the Guidance for Setting Pesticide
Tolerances Based on Field Trial Data
SOP.
2. Cowpea, hay. After reviewing the
cowpea residue data, EPA determined
an additional cowpea tolerance was
necessary on cowpea hay.
3. Livestock feed and milk. Based on
the dietary exposure levels and the
residue data from an available ruminant
feeding study, data indicate that a
tolerance of 0.01 ppm is needed in milk,
whole, 0.20 ppm in milk, fat, 0.02 ppm
is needed for residues of spiromesifen in
the meat of cattle, goats, horses, and
sheep, 0.15 ppm in meat, byproducts, of
cattle, goats, horses, and sheep, and 0.10
in the fat of cattle, goats, horses, and
sheep. Based on the transfer coefficients
for livestock tissues and the relatively
low dietary burden for swine of 0.04
ppm for spiromesifen, tolerances in
hogs are not needed.
V. Conclusion
Therefore, the tolerances are
established for combined residues of
spiromesifen, (2-oxo-3-(2,4,6trimethylphenyl)-1-oxaspiro[4.4]non-3en-4-yl 3,3-dimethylbutanoate) and its
enol metabolite (4-hydroxy-3-(2,4,6trimethylphenyl)-1-oxaspiro[4.4]non-3en-2-one), in or on bean, dry at 0.02
ppm; bean, succulent at 0.10 ppm; bean,
edible podded at 0.80 ppm; cowpea,
forage at 30 ppm; cowpea, hay at 86
ppm; cattle, fat at 0.10 ppm; cattle, meat
at 0.02 ppm; cattle, meat byproducts at
0.15 ppm; goat, fat at 0.10 ppm; goat,
meat at 0.02 ppm; goat, meat byproducts
at 0.15 ppm; horse, fat at 0.10 ppm;
horse, meat at 0.02 ppm; horse, meat

at 0.10 ppm; sheep, meat at 0.02 ppm;
and sheep, meat byproducts at 0.15
ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA 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 rule has
been exempted from review under
Executive Order 12866, this rule is not
subject to Executive Order 13211,
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, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of 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,
1999) and Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 6, 2000) do not apply

to this rule. In addition, This 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).

Program Revisions
Environmental Protection
Agency (EPA).
ACTION: Immediate final rule.
jlentini on PROD1PC65 with RULES
AGENCY:
SUMMARY: The Solid Waste Disposal Act,
as amended, commonly referred to as
the Resource Conservation and
Recovery Act (RCRA), allows the
Environmental Protection Agency (EPA)
to authorize States to operate their
hazardous waste management programs
in lieu of the federal program. Colorado
has applied to EPA for final
authorization of the changes to its
hazardous waste program under RCRA.
EPA has determined that these changes
satisfy all requirements needed to
qualify for final authorization and is
authorizing the State’s changes through
this immediate final action.
DATES: This final authorization will
become effective on May 12, 2008,
unless the EPA receives adverse written
comment by April 11, 2008. If adverse
comment is received, EPA will publish
a timely withdrawal of the immediate
final rule in the Federal Register
informing the public that the rule will
not take effect.

SUPPLEMENTARY INFORMATION:
A. Why Are Revisions to State
Programs Necessary?
States which have received final
authorization from EPA under RCRA
section 3006(b), 42 U.S.C. 6926(b), must
maintain a hazardous waste program
that is equivalent to, consistent with,
and no less stringent than the federal
program. As the federal program
changes, States must change their
programs and ask EPA to authorize the
changes. Changes to State programs may
be necessary when federal or state
statutory or regulatory authority is
modified or when certain other changes
occur. Most commonly, States must
change their programs because of
changes to EPA’s regulations in 40 Code
of Federal Regulations (CFR) parts 124,
260 through 266, 268, 270, 273 and 279.
B. What Decisions Have We Made in
This Rule?
We conclude that Colorado’s
application to revise its authorized
program meets all of the statutory and
regulatory requirements established by
RCRA. Therefore, we grant Colorado
final authorization to operate its
hazardous waste program with the
changes described in the authorization
applications. Colorado has
responsibility for permitting Treatment,
Storage, and Disposal Facilities (TSDFs)
within its borders, except in Indian

II. Petition for Tolerance
In the Federal Register of May 9, 2007 (72 FR 26375) (FRL-8128-1),
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 7E7195)
by IR-4, 500 College Road East, Suite 201 W, Princeton, NJ 08540. The
petition requested that 40 CFR 180.607 be amended by establishing
tolerances for combined residues of the insecticide spiromesifen, (2-
oxo-3-(2,4,6-trimethylphenyl)-1-oxaspiro[4.4]non-3-en-4-yl 3,3-
dimethylbutanoate) and its enol metabolite (4-hydroxy-3-(2,4,6-
trimethylphenyl)-1-oxaspiro[4.4]non-3-en-2-one), in or on bean, edible,
podded at 1.4 ppm; bean, succulent at 0.10 ppm; bean, dry at 0.02 ppm;
cowpea, forage at 35 ppm; cattle, fat at 0.20 ppm; cattle, meat at 0.01
ppm; cattle, meat byproducts at 0.30 ppm; goat, fat at 0.20 ppm; goat,
meat at 0.01 ppm; goat, meat byproducts at 0.30 ppm; hog, fat at 0.20
ppm; hog, meat at 0.01 ppm; hog, meat byproducts at 0.30 ppm; horse,
fat at 0.20 ppm; horse, meat at 0.01 ppm; horse, meat byproducts at0.30
ppm; sheep, fat at 0.20 ppm; sheep, meat at 0.01 ppm; sheep, meat
byproducts at 0.30 ppm; and milk at 0.01 ppm. This notice referenced a
summary of the petition prepared by Bayer Crop Science, 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.
Based upon review of the data supporting the petition, EPA has
revised tolerance expressions for bean, edible, podded; cowpea, forage;
milk, whole; milk, fat; in meat of cattle, goats, horses, and sheep; in
meat, byproducts, of cattle, goats, horses, and sheep; and in fat of
cattle, goats, horses, and sheep. A tolerance for cowpea, hay was also
included. The reason for these changes is explained 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....'' These provisions were added to FFDCA by the Food Quality
Protection Act (FQPA) of 1996.
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 the petitioned-for tolerances
for combined residues of spiromesifen on bean, dry at 0.02 ppm; bean,
succulent at 0.10 ppm; bean, edible podded at 0.80 ppm; cowpea, forage
at 30 ppm; cowpea, hay at 86 ppm; cattle, fat at 0.10 ppm; cattle, meat
at 0.02 ppm; cattle, meat byproducts at 0.15 ppm; goat, fat at 0.10
ppm; goat, meat at 0.02 ppm; goat, meat byproducts at 0.15 ppm; horse,
fat at 0.10 ppm; horse, meat at 0.02 ppm; horse, meat
[[Page 13138]]
byproducts at 0.15 ppm; sheep, fat at 0.10 ppm; sheep, meat at 0.02
ppm; sheep, meat byproducts at 0.15 ppm; milk at 0.01 ppm; and milk,
fat at 0.20 ppm. EPA's assessment of exposures and risks associated
with establishing the tolerances follow.
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.
Spiromesifen shows low acute toxicity via the oral, dermal and
inhalation routes of exposure. It was neither an eye nor dermal
irritant, but showed moderate potential as a contact sensitizer in a
Magnusson and Kligman maximization assay. Acute dietary-exposure limits
for all populations, including infants and children, were not necessary
because an endpoint of concern attributable to a single exposure (dose)
was not identified from the oral toxicity studies. In addition, there
are no developmental concerns based on rat and/or rabbit developmental
toxicity studies. The rat two-generation reproduction study was
selected for chronic dietary, as well as long-term dermal- and
inhalation-exposure risk assessments.
In the 2-generation reproduction study in rat the following effects
were noted at the lowest observed adverse effect level (LOAEL):
Significantly decreased spleen weight (absolute and relative in
parental females and F1 males) and significantly decreased growing
ovarian follicles in females. Spiromesifen shows no significant
developmental or reproductive effects, is not likely to be carcinogenic
based on bioassays in rat and mouse, and lacks in vivo and in vitro
mutagenic effects. Spiromesifen is not a neurotoxic chemical based on
results of acute and subchronic neurotoxicity studies.
Specific information on the studies received and the nature of the
adverse effects caused by spiromesifen 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 in the document
entitled ``Spiromesifen: Human Health Risk Assessment for a Section 3
Registration on Beans;'' pages 44-52 at www.regulations.gov. The
referenced document is available in docket EPA-HQ-OPP-2007-0331.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the toxicological level of concern (LOC) is derived
from 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) is
sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the LOC 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
risks by comparing aggregate 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 LOC by all
applicable UFs. Short-, intermediate-, and long-term risks are
evaluated by comparing aggregate exposure to the LOC to ensure that the
margin of exposure (MOE) called for by the product of all applicable
UFs is not exceeded.
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk and estimates risk in terms
of the probability of occurrence of additional adverse cases.
Generally, cancer risks are considered non-threshold. 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/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
A summary of the toxicological endpoints for spiromesifen used for
human risk assessment can be found at https://www.regulations.gov in the
document entitled ``Spiromesifen: Human Health Risk Assessment for a
Section 3 Registration on Beans;'' pages 18-19; docket ID number EPA-
HQ-OPP-2007-0331.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to spiromesifen, EPA considered exposure under the petitioned-
for tolerances as well as all existing spiromesifen tolerances in (40
CFR 180.607). EPA assessed dietary exposures from spiromesifen 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
spiromesifen; 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 USDA 1994-1996,
and 1998 CSFII. As to residue levels in food, EPA assumed tolerance-
level residues for all commodities with existing and proposed
tolerances except for the leafy-green and leafy-Brassica vegetable
subgroups (4A and 5B). An additional metabolite, BSN 2060-4-
hydroxymethyl, was observed in the metabolism studies of lettuce only.
Since this metabolite's toxicity is expected to be comparable to the
parent compound, it was included in the risk assessment for leafy crops
(subgroups 4A and 5B), but not in the tolerance expression. To account
for this additional toxicity exposure, the recommended tolerance level
was multiplied by a correction factor of 1.3x. For all commodities,
100%CT as well as DEEM\TM\ Version 7.81 default processing factors were
used.
iii. Cancer. Spiromesifen has been classified as ``not likely to be
carcinogenic to humans.'' Therefore, a cancer dietary risk assessment
was not performed.
2. Dietary exposure from drinking water.The Agency lacks sufficient
monitoring data to complete a comprehensive dietary exposure analysis
and risk assessment for spiromesifen in drinking water. Because the
Agency does not have comprehensive monitoring data, drinking water
concentration estimates are made by reliance on simulation or modeling
taking into account data on the environmental fate characteristics of
spiromesifen. 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.
Parent spiromesifen is not likely to persist in the environment as
it readily undergoes both biotic and abiotic degradation; however, its
primary degradate BSN2060 is expected to persist. While parent
spiromensifen strongly sorbs to sediment and is not likely to be
mobile, its enol degradate does not sorb to sediment and is expected to
leach into groundwater. Spiromesifen has limited solubility in water
and is some cases has been
[[Page 13139]]
reported to have a practical solubility limit of 40 to 50 [mu]g/L. The
pesticide degrades primarily through aerobic soil metabolism and
hydrolysis; however, in clear shallow water it will readily undergo
photolysis. Field studies indicate that spiromesifen readily dissipates
with dissipation half lives ranging from 2 to 10 days. The compound is
not likely to bioconcentrate appreciably given its relatively rapid
degradation and depuration.
Spiromesifen and BSN 2060-enol are the predominant residues in
drinking water. BSN 2060-enol may account for 75% of the total acute
exposure and for over 90% for chronic exposure. Estimated drinking
water concentrations (EDWCs) were generated for the total toxic residue
which includes spiromesifen, the -enol and -carboxy metabolites, and
unextracted material. The highest estimated surface water
concentrations occurred with the NC sweet potato scenario.
Based on the Pesticide Root Zone Model /Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated environmental concentration (EEC) of
spiromesifen for chronic exposure is estimated to be 11 parts per
billion (ppb) for surface water. The EEC for chronic exposure is
estimated to be 28 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 28 ppb was used to access
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).
Spiromesifen is not registered for use on any sites that would
result in residential exposure.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
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 spiromesifen and any other
substances and spiromesifen does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that spiromesifen 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 Web site at https://www.epa.gov/pesticides/
cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional (``10X'') tenfold 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. In
applying this provision, EPA either retains the default value of 10X
when reliable data do not support the choice of a different factor, or,
if reliable data are available, EPA uses a different additional FQPA
safety factor value based on the use of traditional UFs and/or special
FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. There is no evidence of
increased susceptibility of rats or rabbits to in utero and/or
postnatal exposure to spiromesifen. In the prenatal developmental
toxicity studies in rats and rabbits and in the two-generation
reproduction study in rats, developmental toxicity to the offspring
occurred at equivalent or higher doses than parental toxicity.
3. Conclusion. EPA has determined that reliable data show that it
would be safe for infants and children to reduce the FQPA safety factor
to 1X. That decision is based on the following findings:
i. The toxicity database for spiromesifen is complete.
ii. There is no indication that spiromesifen 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 spiromesifen 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%CT and tolerance-level residues or higher. Conservative ground
and surface water modeling estimates were used. Residential exposure is
not expected as spiromesifen will be registered for agricultural and
greenhouse/ornamental uses only. These assessments will not
underestimate the exposure and risks posed by spiromesifen.
E. Aggregate Risks and Determination of Safety
Safety is assessed for acute and chronic risks by comparing
aggregate exposure to the pesticide to the aPAD and cPAD. The aPAD and
cPAD are calculated by dividing the LOC by all applicable UFs. For
linear cancer risks, EPA calculates the probability of additional
cancer cases given aggregate exposure. Short-, intermediate-, and long-
term risks are evaluated by comparing aggregate exposure to the LOC to
ensure that the MOE called for by the product of all applicable UFs is
not exceeded.
1. Acute risk. No such effects were identified in the toxicological
studies for spiromesifen; therefore, acute exposure is not expected.
2. Chronic risk.Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
spiromesifen from food and water will utilize 42% of the cPAD for the
population group children 3-5 years old (the greatest exposure). There
are no residential uses for spiromesifen that result in chronic
residential exposure to spiromesifen.
3. Short and intermediate-term risk. Short and Intermediate-term
aggregate exposure takes into account residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level).
Spiromesifen is not registered for use on any sites that would
result in residential exposure. Therefore, the aggregate risk is the
sum of the risk from food and water.
4. Aggregate cancer risk for U.S. population. Spiromesifen has been
classified as ``not likely to be carcinogenic to humans.'' Spiromesifen
is not expected to pose a cancer risk.
5. 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 spiromesifen residues.

IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology, high performance liquid
chromatography/mass spectroscopy (HPLC/MS/MS)/ Method 00631/M001, is
available to enforce the tolerance expression. The method may be
requested from: Chief, Analytical Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone
number: (410) 305-2905; e-mail address: residuemethods@epa.gov.
B. International Residue Limits
No Codex, Canadian, or Mexican MRLs have been established for
residues of spiromesifen and its metabolites.
C. Explanation of Tolerance Revisions
1. Bean, edible podded and cowpea, forage. The tolerances were
revised based on analysis with the Agency's tolerance spreadsheet in
accordance with the Guidance for Setting Pesticide Tolerances Based on
Field Trial Data SOP.
2. Cowpea, hay. After reviewing the cowpea residue data, EPA
determined an additional cowpea tolerance was necessary on cowpea hay.
3. Livestock feed and milk. Based on the dietary exposure levels
and the residue data from an available ruminant feeding study, data
indicate that a tolerance of 0.01 ppm is needed in milk, whole, 0.20
ppm in milk, fat, 0.02 ppm is needed for residues of spiromesifen in
the meat of cattle, goats, horses, and sheep, 0.15 ppm in meat,
byproducts, of cattle, goats, horses, and sheep, and 0.10 in the fat of
cattle, goats, horses, and sheep. Based on the transfer coefficients
for livestock tissues and the relatively low dietary burden for swine
of 0.04 ppm for spiromesifen, tolerances in hogs are not needed.
V. Conclusion
Therefore, the tolerances are established for combined residues of
spiromesifen, (2-oxo-3-(2,4,6-trimethylphenyl)-1-oxaspiro[4.4]non-3-en-
4-yl 3,3-dimethylbutanoate) and its enol metabolite (4-hydroxy-3-
(2,4,6-trimethylphenyl)-1-oxaspiro[4.4]non-3-en-2-one), in or on bean,
dry at 0.02 ppm; bean, succulent at 0.10 ppm; bean, edible podded at
0.80 ppm; cowpea, forage at 30 ppm; cowpea, hay at 86 ppm; cattle, fat
at 0.10 ppm; cattle, meat at 0.02 ppm; cattle, meat byproducts at 0.15
ppm; goat, fat at 0.10 ppm; goat, meat at 0.02 ppm; goat, meat
byproducts at 0.15 ppm; horse, fat at 0.10 ppm; horse, meat at 0.02
ppm; horse, meat byproducts at 0.15 ppm; milk at 0.01 ppm; milk, fat at
0.20 ppm; sheep, fat at 0.10 ppm; sheep, meat at 0.02 ppm; and sheep,
meat byproducts at 0.15 ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA 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 rule has been
exempted from review under Executive Order 12866, this rule is not
subject to Executive Order 13211, 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, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of 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, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 6, 2000) do not apply to this rule. In addition, This
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).
