ENVIRONMENTAL PROTECTION
AGENCY
Environmental Protection
Agency (EPA).
ACTION: Final rule.
AGENCY:
This regulation establishes an
exemption from the requirement of a
tolerance for residues of D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives (CAS Reg. No. 1591782–62–
5) when used as an inert ingredient
(surfactant) applied to growing crops
and raw agricultural commodities after
harvest at a concentration not to exceed
40% by weight under 40 CFR 180.910.
Keller & Heckman LLP on behalf of the
Clariant Corporation submitted a
petition to EPA under the Federal Food,
Drug, and Cosmetic Act (FFDCA),
requesting establishment of an
exemption from the requirement of a
tolerance. This regulation eliminates the
need to establish a maximum
permissible level for residues of Dglucitol, 1-deoxy-1-(methylamino)-,
N-C8-10 acyl derivatives.

II. Petition for Exemption
In the Federal Register of August 26,
2015 (80 FR 51762) (FRL–9931–74),
EPA issued a document pursuant to
FFDCA section 408, 21 U.S.C. 346a,
announcing the filing of a pesticide
petition (PP IN–10792) by Keller &
Heckman LLP (1001 G Street NW., Suite
500 West, Washington, DC 20001), on
behalf of the Clariant Corporation (4000
Monroe Road, Charlotte, NC 28205). The
petition requested that 40 CFR 180.910
be amended by establishing an
exemption from the requirement of a
tolerance for residues of D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives (CAS Reg. No. 1591782–62–
5) when used as an inert ingredient
(surfactant) in pesticide formulations
applied to growing crops and raw
agricultural commodities at a
concentration in formulations not to
exceed 40% by weight. That document
referenced a summary of the petition
prepared by Keller & Heckman on behalf
of the Clariant Corporation, the
petitioner, which is available in the
docket, https://www.regulations.gov.
There were no comments received in
response to the notice of filing.
III. Inert Ingredient Definition
Inert ingredients are all ingredients
that are not active ingredients as defined
in 40 CFR 153.125 and include, but are
not limited to, the following types of
ingredients (except when they have a
pesticidal efficacy of their own):
Solvents such as alcohols and
E:\FR\FM\26FER1.SGM
26FER1

hydrocarbons; surfactants such as
polyoxyethylene polymers and fatty
acids; carriers such as clay and
diatomaceous earth; thickeners such as
carrageenan and modified cellulose;
wetting, spreading, and dispersing
agents; propellants in aerosol
dispensers; microencapsulating agents;
and emulsifiers. The term ‘‘inert’’ is not
intended to imply nontoxicity; the
ingredient may or may not be
chemically active. Generally, EPA has
exempted inert ingredients from the
requirement of a tolerance based on the
low toxicity of the individual inert
ingredients.
Consistent with FFDCA section
408(c)(2)(A), and the factors specified in
FFDCA section 408(c)(2)(B), 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 D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives including exposure resulting
from the exemption established by this
action. EPA’s assessment of exposures
and risks associated with D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives follows.
IV. Aggregate Risk Assessment and
Determination of Safety
Section 408(c)(2)(A)(i) of FFDCA
allows EPA to establish an exemption
from the requirement for 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. . . .’’
EPA establishes exemptions from the
requirement of a tolerance only in those
cases where it can be clearly
demonstrated that the risks from
aggregate exposure to pesticide
chemical residues under reasonably
foreseeable circumstances will pose no
appreciable risks to human health. In
order to determine the risks from
aggregate exposure to pesticide inert
ingredients, the Agency considers the
toxicity of the inert in conjunction with
possible exposure to residues of the
inert ingredient through food, drinking
water, and through other exposures that
occur as a result of pesticide use in
residential settings. If EPA is able to
determine that a finite tolerance is not
necessary to ensure that there is a
reasonable certainty that no harm will
result from aggregate exposure to the
inert ingredient, an exemption from the
requirement of a tolerance may be
established.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered their
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. Specific
information on the studies received and
the nature of the adverse effects caused
by D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives
as well as the no-observed-adverseeffect-level (NOAEL) and the lowestobserved-adverse-effect-level (LOAEL)
from the toxicity studies are discussed
in this unit.
D-Glucitol, 1-deoxy-1-(methylamino)-,
N-C8-10 acyl derivatives exhibits low
acute toxicity. The oral lethal dose
(LD)50 in the rat is 500 milligram/
kilogram (mg/kg) and above. The dermal
LD50 in rats and rabbits was determined
to be >2,000 mg/kg. The inhalation
lethal concentration (LC)50 value for
Wistar rats is greater than 1 milligram
per Liter (mg/L). A primary skin
irritation test with the rabbit indicates it
is not irritating to rabbit’s skin. An eye
irritation test with New Zealand white
rabbits indicates it to be moderately
irritating. Two skin sensitization tests
with Hartley guinea pigs show it is not
a sensitizer to the guinea pig.
A 28-day repeat dose oral toxicity
study was conducted with Wistar rats.
In this study, rats were treated via
gavage with D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 derivatives at
doses up to 500 milligram/kilogram/day
(mg/kg/day). At the 500 mg/kg/day
dose, mortality was observed as well as
toxicity reflected as microscopic
findings in the GI tract, trachea, lung,
spleen and bone marrow. The NOAEL
was 250 mg/kg/day.
In a reproduction/developmental
toxicity screening test, rats were dosed
for 54 days with D-glucitol, 1-deoxy-1-

(methylamino)-, N-C8-10 derivatives at
doses up to 312.5 mg/kg/day. Neither
parental, developmental nor
reproduction toxicity was observed at
312.5 mg/kg/day, the highest dose tested
(HDT).
A gene reverse mutation study with
Salmonella, an in vitro mammalian cell
gene mutation study with Chinese
hamster V 79 cells, a mammalian
micronucleus mutagenicity test of
micronuclei in polychromatic
erythrocytes in the mouse bone marrow,
a mammalian micronucleus test with
murine peripheral blood cells, a
mutagenesis assay using L5178Y TK+/mouse lymphoma cells, an in vivo rat
bone marrow cytogenicity study all
were negative for mutagenic and
clastogenic effects.
There were no neurotoxicity data per
se however there were no indications of
neurotoxic effects in the functional
observation battery in the 28-day oral
toxicity study in the rat. In addition, the
DEREK predictive modeling system did
not identify any alerts for potential
neurotoxicity.
There were no data regarding
immunotoxicity. However evidence of
potential immunotoxicity was observed
in the 28-day oral toxicity study in the
rat. In this study, atrophy is seen in the
spleen and bone marrow at 500 mg/kg/
day. These effects will be protected
since the established chronic reference
dose (cRfD) is 1.04 mg/kg/day.
There were no study data presented
specifically addressing metabolism.
Modeling data using the DEREK (Nexus)
and METEOR modeling systems
indicate 80% absorption via the
gastrointestinal system and less than 1%
via dermal absorption. The major route
of excretion is via the urine.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which the NOAEL and the
LOAEL are identified. 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
E:\FR\FM\26FER1.SGM

9780
Federal Register / Vol. 81, No. 38 / Friday, February 26, 2016 / Rules and Regulations

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://
www.epa.gov/pesticides/factsheets/
riskassess.htm.
An acute effect was not found in the
database therefore an acute dietary
assessment is not necessary. The
reproduction/developmental toxicity
screening study in the rat was selected
for the toxicological endpoint for use in
the chronic dietary risk assessment. In
this study, no effects are observed up to
312.5 mg/kg/day. The standard
uncertainty factors (100X) are applied
for intra-and interspecies variation and
an additional uncertainty factor (3X) is
applied to account for extrapolation
from subchronic to chronic exposures.
EPA identified the uncertainty factor of
3X as protective rather than 10X is
because there was no toxicity observed
at doses up to 312.5 mg/kg/day in an
Organization for Economic Cooperation
and Development (OECD) 422 study.
Dermal and inhalation absorption are
assumed to be 100%. For all short- and
intermediate-term residential risk
assessments, the toxicological endpoint
selected for use in the assessment is
taken from the reproduction/
developmental toxicity screening study
in the rat. In this study, no effects are
observed up to 312.5 mg/kg/day. The
level of concern for residential risk
assessments is for MOEs of less than
300.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 derivatives,
EPA considered exposure under the
proposed exemption from the
requirement of a tolerance. EPA
assessed dietary exposures from Dglucitol, 1-deoxy-1-(methylamino)-, NC8-10 derivatives, in food as follows:
Dietary exposure (food and drinking
water) to D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 derivatives can
occur following ingestion of foods with
residues from treated crops. An acute
dietary risk assessment was not
conducted because no endpoint of
concern following a single exposure was
identified in the available studies. A
chronic dietary exposure assessment
was completed and performed using the
Dietary Exposure Evaluation Model
DEEM–FCIDTM, Version 3.16, which
VerDate Sep<11>2014
17:33 Feb 25, 2016
Jkt 238001
includes food consumption information
from the U.S. Department of
Agriculture’s National Health and
Nutrition Examination Survey, ‘‘What
We Eat In America’’, (NHANES/
WWEIA). This dietary survey was
conducted from 2003 to 2008. In the
absence of actual residue data, the inert
ingredient evaluation is based on a
highly conservative model that assumes
that the residue level of the inert
ingredient would be no higher than the
highest established tolerance for an
active ingredient on a given commodity.
Implicit in this assumption is that there
would be similar rates of degradation
between the active and inert ingredient
(if any) and that the concentration of
inert ingredient in the scenarios leading
to these highest of tolerances would be
no higher than the concentration of the
active ingredient. The model assumes
100 percent crop treated (PCT) for all
crops and that every food eaten by a
person each day has tolerance-level
residues. A complete description of the
general approach taken to assess inert
ingredient risks in the absence of
residue data is contained in the
memorandum entitled ‘‘Alkyl Amines
Polyalkoxylates (Cluster 4): Acute and
Chronic Aggregate (Food and Drinking
Water) Dietary Exposure and Risk
Assessments for the Inerts’’ (D361707, S.
Piper, 2/25/09) and can be found at
https://www.regulations.gov in docket ID
number EPA–HQ–OPP–2008–0738.
2. Dietary exposure from drinking
water. For the purpose of the screening
level dietary risk assessment to support
this request for an exemption from the
requirement of a tolerance for Dglucitol, 1-deoxy-1-(methylamino)-, NC8-10 derivatives, a conservative
drinking water concentration value of
100 parts per billion (ppb) based on
screening level modeling was used to
assess the contribution to drinking
water for the chronic dietary risk
assessments for parent compound.
These values were directly entered into
the dietary exposure model.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., textiles (clothing and diapers),
carpets, swimming pools, and hard
surface disinfection on walls, floors,
tables).
D-Glucitol, 1-deoxy-1-(methylamino)-,
N–C8-10 derivatives may be used in inert
ingredients in products that are
registered for specific uses that may
result in residential exposure, such as
pesticides used in and around the home.
The Agency conducted an assessment to
represent worst-case residential
exposure by assessing D-glucitol, 1-
PO 00000
Frm 00040

Sfmt 4700
deoxy-1-(methylamino)-, N-C8-10
derivatives in pesticide formulations
(outdoor scenarios) and in disinfectanttype uses (indoor scenarios).
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
EPA has not found D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives to share a common
mechanism of toxicity with any other
substances, and D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives
does not appear to produce a toxic
metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives
does not have a common mechanism of
toxicity with other substances. For
information regarding EPA’s efforts to
determine which chemicals have a
common mechanism of toxicity and to
evaluate the cumulative effects of such
chemicals, see EPA’s Web site at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
Food Quality Protection Act Safety
Factor (FQPA SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no evidence of increased
susceptibility in the OECD 422 study
based on lack of systemic toxicity in the
maternal animals and offspring at doses
up to 312.5 mg/kg/day; the HDT.
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 3X. That decision is
based on the following findings:

i. The toxicity database for D-glucitol,
1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives contains the following
studies that are adequate to evaluate the
potential toxicity of D-glucitol, 1-deoxy1-(methylamino)-, N-C8-10 acyl
derivatives for infants and children: The
database contains a 28-day repeat dose
oral toxicity study, a reproduction/
developmental toxicity screening study
and several mutagenicity studies.
ii. There were no neurotoxicity data
per se however there were no
indications of neurotoxic effects in the
functional observation battery in the 28day oral toxicity study in the rat.
iii. There were no data regarding
immunotoxicity. However evidence of
potential immunotoxicity was observed
in the 28-day oral toxicity study in the
rat. In this study, atrophy is seen in the
spleen and bone marrow at 500 mg/kg/
day. These effects will be protected
since the established cRfD is 1.04 mg/
kg/day.
iv. There was no evidence of
increased susceptibility of infants and
children in the OECD 422 study.
v. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100 percent
crop treated (PCT) and tolerance-level
residues. EPA made conservative
(protective) assumptions in the ground
and surface water modeling used to
assess exposure to D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives
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 D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives
E. Aggregate Risks and Determination of
Safety
Determination of safety section. 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
VerDate Sep<11>2014
17:33 Feb 25, 2016
Jkt 238001
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, D-glucitol, 1-deoxy1-(methylamino)-, N-C8-10 acyl
derivatives 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 D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives from food and water will
utilize 54.4% of the cPAD for children
1–2 years old, the population group
receiving the greatest exposure.
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).
D-glucitol, 1-deoxy-1-(methylamino)-,
N-C8-10 acyl derivatives may be used as
inert ingredients in pesticide products
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 D-glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives.
Using the exposure assumptions
described above, EPA has concluded
that the combined short-term aggregated
food, water, and residential exposures
result in MOEs of 490 for both adult
males and females respectively. Adult
residential exposure combines high-end
dermal and inhalation handler exposure
from indoor hard surface, mopping,
wiping and trigger-pump spray. As the
level of concern is for MOEs that are
lower than 300, this MOE is not of
concern. EPA has concluded the
combined short-term aggregated food,
water, and residential exposures result
in an aggregate MOE of 420 for children
As the level of concern is for MOEs that
are lower than 300, this MOE is not of
concern.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level). DGlucitol, 1-deoxy-1-(methylamino)-, NC8-10 acyl derivatives may be used as
inert ingredients in pesticide products
that could result in intermediate -term
residential exposure and the Agency has
determined that it is appropriate to
aggregate chronic exposure through food
and water with intermediate-term
residential exposures to D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives. Using the exposure
assumptions described above, EPA has
concluded that the combined
PO 00000
Frm 00041
Fmt 4700
Sfmt 4700
9781
intermediate-term aggregated food,
water, and residential exposures result
in aggregate MOEs of 490 for adult
males and females. Adult residential
exposure combines indoor hard surface,
wiping with a high end post application
dermal exposure from contact with
treated lawns. As the level of concern is
for MOEs that are lower than 300, this
MOE is not of concern. EPA has
concluded the combined intermediateterm aggregated food, water, and
residential exposures result in an
aggregate MOE of 420 for children.
Children’s residential exposure includes
total exposures associated with contact
with treated surfaces (dermal and handto-mouth exposures). As the level of
concern is for MOEs that are lower than
300, this MOE is not of concern.
5. Aggregate cancer risk for U.S.
population. Based on a DEREK
structural alert analysis and the lack of
mutagenicity, D-Glucitol, 1-deoxy-1(methylamino)-, N-C8-10 acyl derivatives
not expected to pose a cancer risk to
humans.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is not establishing a numerical
tolerance for residues of D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives in or on any food
commodities. EPA is establishing a
limitation on the amount of D-glucitol,
1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives that may be used in
pesticide formulations applied to
growing crops. That limitation will be
enforced through the pesticide
registration process under the Federal
Insecticide, Fungicide, and Rodenticide
Act (FIFRA), 7 U.S.C. 136 et seq. EPA
will not register any pesticide
formulation for use on growing crops for
sale or distribution that exceed 40% of
D-glucitol, 1-deoxy-1-(methylamino)-,
N-C8-10 acyl derivatives.
VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.910 for D-glucitol, 1deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives when used as an inert
ingredient (surfactant) in pesticide
formulations applied to growing crops

VII. Statutory and Executive Order
Reviews
This action establishes a tolerance
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This action does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this action. In addition, this action
does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
Inert ingredients
VIII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule in the Federal
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).

D-Glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives; Exemption From the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of D-glucitol, 1-deoxy-1-(methylamino)-, N-
C8-10 acyl derivatives (CAS Reg. No. 1591782-62-5) when used
as an inert ingredient (surfactant) applied to growing crops and raw
agricultural commodities after harvest at a concentration not to exceed
40% by weight under 40 CFR 180.910. Keller & Heckman LLP on behalf of
the Clariant Corporation submitted a petition to EPA under the Federal
Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an
exemption from the requirement of a tolerance. This regulation
eliminates the need to establish a maximum permissible level for
residues of D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10
acyl derivatives.
DATES: This regulation is effective February 26, 2016. Objections and

II. Petition for Exemption
In the Federal Register of August 26, 2015 (80 FR 51762) (FRL-9931-
74), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C.
346a, announcing the filing of a pesticide petition (PP IN-10792) by
Keller & Heckman LLP (1001 G Street NW., Suite 500 West, Washington, DC
20001), on behalf of the Clariant Corporation (4000 Monroe Road,
Charlotte, NC 28205). The petition requested that 40 CFR 180.910 be
amended by establishing an exemption from the requirement of a
tolerance for residues of D-glucitol, 1-deoxy-1-(methylamino)-, N-
C8-10 acyl derivatives (CAS Reg. No. 1591782-62-5) when used
as an inert ingredient (surfactant) in pesticide formulations applied
to growing crops and raw agricultural commodities at a concentration in
formulations not to exceed 40% by weight. That document referenced a
summary of the petition prepared by Keller & Heckman on behalf of the
Clariant Corporation, the petitioner, which is available in the docket,
https://www.regulations.gov. There were no comments received in response
to the notice of filing.
III. Inert Ingredient Definition
Inert ingredients are all ingredients that are not active
ingredients as defined in 40 CFR 153.125 and include, but are not
limited to, the following types of ingredients (except when they have a
pesticidal efficacy of their own): Solvents such as alcohols and
[[Page 9779]]
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty
acids; carriers such as clay and diatomaceous earth; thickeners such as
carrageenan and modified cellulose; wetting, spreading, and dispersing
agents; propellants in aerosol dispensers; microencapsulating agents;
and emulsifiers. The term ``inert'' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active.
Generally, EPA has exempted inert ingredients from the requirement of a
tolerance based on the low toxicity of the individual inert
ingredients.
IV. Aggregate Risk Assessment and Determination of Safety
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for 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. . . .''
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be clearly demonstrated that the risks from
aggregate exposure to pesticide chemical residues under reasonably
foreseeable circumstances will pose no appreciable risks to human
health. In order to determine the risks from aggregate exposure to
pesticide inert ingredients, the Agency considers the toxicity of the
inert in conjunction with possible exposure to residues of the inert
ingredient through food, drinking water, and through other exposures
that occur as a result of pesticide use in residential settings. If EPA
is able to determine that a finite tolerance is not necessary to ensure
that there is a reasonable certainty that no harm will result from
aggregate exposure to the inert ingredient, an exemption from the
requirement of a tolerance may be established.
Consistent with FFDCA section 408(c)(2)(A), and the factors
specified in FFDCA section 408(c)(2)(B), 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 D-glucitol, 1-deoxy-1-
(methylamino)-, N-C8-10 acyl derivatives including exposure
resulting from the exemption established by this action. EPA's
assessment of exposures and risks associated with D-glucitol, 1-deoxy-
1-(methylamino)-, N-C8-10 acyl derivatives follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered their
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. Specific information on the studies received and the nature
of the adverse effects caused by D-glucitol, 1-deoxy-1- (methylamino)-,
N-C8-10 acyl derivatives as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the toxicity studies are discussed in this unit.
D-Glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives exhibits low acute toxicity. The oral lethal dose
(LD)50 in the rat is 500 milligram/kilogram (mg/kg) and
above. The dermal LD50 in rats and rabbits was determined to
be >2,000 mg/kg. The inhalation lethal concentration (LC)50
value for Wistar rats is greater than 1 milligram per Liter (mg/L). A
primary skin irritation test with the rabbit indicates it is not
irritating to rabbit's skin. An eye irritation test with New Zealand
white rabbits indicates it to be moderately irritating. Two skin
sensitization tests with Hartley guinea pigs show it is not a
sensitizer to the guinea pig.
A 28-day repeat dose oral toxicity study was conducted with Wistar
rats. In this study, rats were treated via gavage with D-glucitol, 1-
deoxy-1-(methylamino)-, N-C8-10 derivatives at doses up to
500 milligram/kilogram/day (mg/kg/day). At the 500 mg/kg/day dose,
mortality was observed as well as toxicity reflected as microscopic
findings in the GI tract, trachea, lung, spleen and bone marrow. The
NOAEL was 250 mg/kg/day.
In a reproduction/developmental toxicity screening test, rats were
dosed for 54 days with D-glucitol, 1-deoxy-1-(methylamino)-, N-
C8-10 derivatives at doses up to 312.5 mg/kg/day. Neither
parental, developmental nor reproduction toxicity was observed at 312.5
mg/kg/day, the highest dose tested (HDT).
A gene reverse mutation study with Salmonella, an in vitro
mammalian cell gene mutation study with Chinese hamster V 79 cells, a
mammalian micronucleus mutagenicity test of micronuclei in
polychromatic erythrocytes in the mouse bone marrow, a mammalian
micronucleus test with murine peripheral blood cells, a mutagenesis
assay using L5178Y TK+/- mouse lymphoma cells, an in vivo rat bone
marrow cytogenicity study all were negative for mutagenic and
clastogenic effects.
There were no neurotoxicity data per se however there were no
indications of neurotoxic effects in the functional observation battery
in the 28-day oral toxicity study in the rat. In addition, the DEREK
predictive modeling system did not identify any alerts for potential
neurotoxicity.
There were no data regarding immunotoxicity. However evidence of
potential immunotoxicity was observed in the 28-day oral toxicity study
in the rat. In this study, atrophy is seen in the spleen and bone
marrow at 500 mg/kg/day. These effects will be protected since the
established chronic reference dose (cRfD) is 1.04 mg/kg/day.
There were no study data presented specifically addressing
metabolism. Modeling data using the DEREK (Nexus) and METEOR modeling
systems indicate 80% absorption via the gastrointestinal system and
less than 1% via dermal absorption. The major route of excretion is via
the urine.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which the NOAEL and the LOAEL are identified.
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
[[Page 9780]]
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://www.epa.gov/pesticides/factsheets/riskassess.htm.
An acute effect was not found in the database therefore an acute
dietary assessment is not necessary. The reproduction/developmental
toxicity screening study in the rat was selected for the toxicological
endpoint for use in the chronic dietary risk assessment. In this study,
no effects are observed up to 312.5 mg/kg/day. The standard uncertainty
factors (100X) are applied for intra-and interspecies variation and an
additional uncertainty factor (3X) is applied to account for
extrapolation from subchronic to chronic exposures. EPA identified the
uncertainty factor of 3X as protective rather than 10X is because there
was no toxicity observed at doses up to 312.5 mg/kg/day in an
Organization for Economic Cooperation and Development (OECD) 422 study.
Dermal and inhalation absorption are assumed to be 100%. For all short-
and intermediate-term residential risk assessments, the toxicological
endpoint selected for use in the assessment is taken from the
reproduction/developmental toxicity screening study in the rat. In this
study, no effects are observed up to 312.5 mg/kg/day. The level of
concern for residential risk assessments is for MOEs of less than 300.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10
derivatives, EPA considered exposure under the proposed exemption from
the requirement of a tolerance. EPA assessed dietary exposures from D-
glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 derivatives, in
food as follows: Dietary exposure (food and drinking water) to D-
glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 derivatives can
occur following ingestion of foods with residues from treated crops. An
acute dietary risk assessment was not conducted because no endpoint of
concern following a single exposure was identified in the available
studies. A chronic dietary exposure assessment was completed and
performed using the Dietary Exposure Evaluation Model DEEM-FCID\TM\,
Version 3.16, which includes food consumption information from the U.S.
Department of Agriculture's National Health and Nutrition Examination
Survey, ``What We Eat In America'', (NHANES/WWEIA). This dietary survey
was conducted from 2003 to 2008. In the absence of actual residue data,
the inert ingredient evaluation is based on a highly conservative model
that assumes that the residue level of the inert ingredient would be no
higher than the highest established tolerance for an active ingredient
on a given commodity. Implicit in this assumption is that there would
be similar rates of degradation between the active and inert ingredient
(if any) and that the concentration of inert ingredient in the
scenarios leading to these highest of tolerances would be no higher
than the concentration of the active ingredient. The model assumes 100
percent crop treated (PCT) for all crops and that every food eaten by a
person each day has tolerance-level residues. A complete description of
the general approach taken to assess inert ingredient risks in the
absence of residue data is contained in the memorandum entitled ``Alkyl
Amines Polyalkoxylates (Cluster 4): Acute and Chronic Aggregate (Food
and Drinking Water) Dietary Exposure and Risk Assessments for the
Inerts'' (D361707, S. Piper, 2/25/09) and can be found at https://www.regulations.gov in docket ID number EPA-HQ-OPP-2008-0738.
2. Dietary exposure from drinking water. For the purpose of the
screening level dietary risk assessment to support this request for an
exemption from the requirement of a tolerance for D-glucitol, 1-deoxy-
1-(methylamino)-, N-C8-10 derivatives, a conservative
drinking water concentration value of 100 parts per billion (ppb) based
on screening level modeling was used to assess the contribution to
drinking water for the chronic dietary risk assessments for parent
compound. These values were directly entered into the dietary exposure
model.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., textiles (clothing and diapers), carpets, swimming
pools, and hard surface disinfection on walls, floors, tables).
D-Glucitol, 1-deoxy-1-(methylamino)-, N-C8-10
derivatives may be used in inert ingredients in products that are
registered for specific uses that may result in residential exposure,
such as pesticides used in and around the home. The Agency conducted an
assessment to represent worst-case residential exposure by assessing D-
glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 derivatives in
pesticide formulations (outdoor scenarios) and in disinfectant-type
uses (indoor scenarios).
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA has not found D-glucitol, 1-deoxy-1-(methylamino)-, N-
C8-10 acyl derivatives to share a common mechanism of
toxicity with any other substances, and D-glucitol, 1-deoxy-1-
(methylamino)-, N-C8-10 acyl derivatives does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that D-
glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl derivatives
does not have a common mechanism of toxicity with other substances. For
information regarding EPA's efforts to determine which chemicals have a
common mechanism of toxicity and to evaluate the cumulative effects of
such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the Food Quality
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA
either retains the default value of 10X, or uses a different additional
safety factor when reliable data available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity. There is no evidence of
increased susceptibility in the OECD 422 study based on lack of
systemic toxicity in the maternal animals and offspring at doses up to
312.5 mg/kg/day; the HDT.
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 3X. That decision is based on the following
findings:
[[Page 9781]]
i. The toxicity database for D-glucitol, 1-deoxy-1-(methylamino)-,
N-C8-10 acyl derivatives contains the following studies that
are adequate to evaluate the potential toxicity of D-glucitol, 1-deoxy-
1-(methylamino)-, N-C8-10 acyl derivatives for infants and
children: The database contains a 28-day repeat dose oral toxicity
study, a reproduction/developmental toxicity screening study and
several mutagenicity studies.
ii. There were no neurotoxicity data per se however there were no
indications of neurotoxic effects in the functional observation battery
in the 28-day oral toxicity study in the rat.
iii. There were no data regarding immunotoxicity. However evidence
of potential immunotoxicity was observed in the 28-day oral toxicity
study in the rat. In this study, atrophy is seen in the spleen and bone
marrow at 500 mg/kg/day. These effects will be protected since the
established cRfD is 1.04 mg/kg/day.
iv. There was no evidence of increased susceptibility of infants
and children in the OECD 422 study.
v. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100 percent crop treated (PCT) and tolerance-level residues. EPA
made conservative (protective) assumptions in the ground and surface
water modeling used to assess exposure to D-glucitol, 1-deoxy-1-
(methylamino)-, N-C8-10 acyl derivatives 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 D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives
E. Aggregate Risks and Determination of Safety
Determination of safety section. 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,
D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives 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
D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives from food and water will utilize 54.4% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure.
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).
D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives may be used as inert ingredients in pesticide products 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 D-glucitol, 1-
deoxy-1-(methylamino)-, N-C8-10 acyl derivatives. Using the
exposure assumptions described above, EPA has concluded that the
combined short-term aggregated food, water, and residential exposures
result in MOEs of 490 for both adult males and females respectively.
Adult residential exposure combines high-end dermal and inhalation
handler exposure from indoor hard surface, mopping, wiping and trigger-
pump spray. As the level of concern is for MOEs that are lower than
300, this MOE is not of concern. EPA has concluded the combined short-
term aggregated food, water, and residential exposures result in an
aggregate MOE of 420 for children As the level of concern is for MOEs
that are lower than 300, this MOE is not of concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). D-Glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives may be used as inert ingredients in pesticide products that
could result in intermediate -term residential exposure and the Agency
has determined that it is appropriate to aggregate chronic exposure
through food and water with intermediate-term residential exposures to
D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives. Using the exposure assumptions described above, EPA has
concluded that the combined intermediate-term aggregated food, water,
and residential exposures result in aggregate MOEs of 490 for adult
males and females. Adult residential exposure combines indoor hard
surface, wiping with a high end post application dermal exposure from
contact with treated lawns. As the level of concern is for MOEs that
are lower than 300, this MOE is not of concern. EPA has concluded the
combined intermediate-term aggregated food, water, and residential
exposures result in an aggregate MOE of 420 for children. Children's
residential exposure includes total exposures associated with contact
with treated surfaces (dermal and hand-to-mouth exposures). As the
level of concern is for MOEs that are lower than 300, this MOE is not
of concern.
5. Aggregate cancer risk for U.S. population. Based on a DEREK
structural alert analysis and the lack of mutagenicity, D-Glucitol, 1-
deoxy-1-(methylamino)-, N-C8-10 acyl derivatives not
expected to pose a cancer risk to humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10
acyl derivatives residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is not establishing a numerical tolerance for residues of D-
glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl derivatives
in or on any food commodities. EPA is establishing a limitation on the
amount of D-glucitol, 1-deoxy-1-(methylamino)-, N-C8-10 acyl
derivatives that may be used in pesticide formulations applied to
growing crops. That limitation will be enforced through the pesticide
registration process under the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA), 7 U.S.C. 136 et seq. EPA will not register any
pesticide formulation for use on growing crops for sale or distribution
that exceed 40% of D-glucitol, 1-deoxy-1-(methylamino)-, N-
C8-10 acyl derivatives.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.910 for D-glucitol, 1-deoxy-1-
(methylamino)-, N-C8-10 acyl derivatives when used as an
inert ingredient (surfactant) in pesticide formulations applied to
growing crops
[[Page 9782]]
and raw agricultural commodities at a concentration not to exceed 40%
by weight.
VII. Statutory and Executive Order Reviews
This action establishes a tolerance under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
VIII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
