II. Petition for Exemption
In the Federal Register of April 11,
2018 (83 FR 15528) (FRL–9975–57),
EPA issued a document pursuant to
FFDCA section 408, 21 U.S.C. 346a,
announcing the filing of a pesticide
petition (PP IN–11075) by ADAMA
Agan, Ltd. c/o Makhteshim Agan of
North America, Inc., 3120 Highwoods
Blvd., Suite 100, Raleigh, NC 27604.
The petition requested that 40 CFR
180.920 be amended by establishing an
exemption from the requirement of a
tolerance for residues of calcium
formate (CAS Reg. No. 544–17–2) when
used as an inert ingredient (carrier) in
pesticide formulations applied to
growing crops only. That document
referenced a summary of the petition
prepared by ADAMA Agan, LTD, the
petitioner, which is available in the
docket, https://www.regulations.gov.
This is based on the Agency’s risk
assessment which can be found at

Health Risk Assessment in docket ID
number EPA–HQ–OPP–2018–0091. No
comments were received in response to
the notice published by EPA.
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
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.
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 calcium formate
including exposure resulting from the
exemption established by this action.
EPA’s assessment of exposures and risks
associated with calcium formate
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.
Consistent with FFDCA section
408(c)(2)(A), and the factors specified in
FFDCA section 408(c)(2)(B), EPA has
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.
The toxicity database on calcium
formate is somewhat limited.
Consequently, studies on appropriate
surrogates were used to supplement the
database on calcium formate. Formic
acid, sodium formate, potassium
formate and ammonium formate were
selected as appropriate surrogates since
they are either the acid form of calcium
formate or other salts of formic acid.
Calcium formate is not expected to be
acutely toxic based on acute toxicity
data. There are no subchronic or chronic
studies on calcium formate, although
there are studies on potassium formate.
These studies show effects based on
reduced body weight gain. A two-year
study with potassium formate indicates
the compound is not carcinogenic to
Wistar rats.
In mutagenicity studies with calcium
formate, sodium formate and methyl
formate, results of the test were negative
for all chemicals. The weight-ofevidence suggests that calcium is not
expected to be mutagenic.
There are no available developmental
toxicity studies on calcium formate;
however, both a rat and rabbit
developmental toxicity study have been
conducted on sodium formate. In the rat
study, the maternal and developmental
no-observed-adverse-effect-level
(NOAEL) was considered the highest
dose tested at 945 milligram/kilogram/
day (mg/kg/day). In the rabbit study, the
maternal and developmental toxicity
NOAEL was also the highest dose tested
at 1,000 mg/kg/day. A five-generation
rat reproductive toxicity study on
calcium formate has been conducted
with a NOAEL of >200 mg/kg/day (only
dose tested). In a three-generation
reproduction study in rats via drinking
water, no treatment related effects were

observed in the parental animals and off
springs at doses up to 200 mg/kg/day.
No studies were submitted for
immunotoxicity. However, the toxicity
studies available did not show any signs
of immunotoxicity up to limit doses.
Therefore, immunotoxicity is not of
concern.
There are no available studies for
neurotoxicity. However, the functional
observation battery performed in the 90day oral toxicity study did not show any
signs of neurotoxicity up to limit doses.
Therefore, neurotoxicity is not of
concern.
A metabolism study is available in the
toxicity database. Calcium formate
breaks down into calcium and formate
ions. Calcium ions are ubiquitous in the
natural environment and can be
considered as having little toxicity or
hazard. Formate ions are readily
converted to carbon dioxide in the
environment by biodegradation or
photooxidation.
Specific information on the studies
received and the nature of the adverse
effects caused by calcium formate as
well as the NOAEL and the lowestobserved-adverse-effect-level (LOAEL)
from the toxicity studies can be found
at https://www.regulations.gov in the
document Calcium Formate Risk
Assessment at page 7 in docket ID
number EPA–HQ–OPP–2018–0091.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
E:\FR\FM\04DER1.SGM
04DER1

complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/
riskassess.htm.
No toxicological endpoints of concern
were identified for calcium formate
based on available toxicity studies on
surrogate chemicals. Formic acid,
sodium formate, potassium formate and
ammonium formate were selected as
appropriate surrogates since they are
either the acid form of calcium formate
or other salts of formic acid. Most of the
available studies on these substances
were not conducted up to the limit dose.
The highest dose of 200 mg/kg/day in a
lifelong study in rats via drinking water
did not produce any systemic toxicity
(IUCLID, Calcium formate, 2001).
Therefore, a conservative risk
assessment was conducted using a
NOAEL of 200 mg/kg/day for chronic
dietary and short- and intermediateterm dermal exposure risk estimates. An
uncertainty/safety factor of 100X (10X
for interspecies variability and 10X for
interspecies extrapolation) was used.
The Food Quality Protection Act
(FQPA) factor of 10X was reduced to 1X,
therefore, the chronic Reference Dose
(cRfD) of 2 mg/kg/day is equal to the
chronic Population Adjusted Dose
(cPAD). A 100% dermal absorption
factor is assumed for converting oral to
dermal equivalent doses in the absence
of dermal toxicity or dermal absorption
studies.
For short and intermediate term
inhalation exposure, the route specific
study was used. The NOAEL of 0.62 mg/
l (32 parts per million (ppm)) was
observed in a 90-day inhalation toxicity
study in rats (IUCLID, Formic acid,
2000). The uncertainty factor is 100X
(10X for interspecies variability and IOX
for interspecies extrapolation). The
FQPA factor of 10 X was reduced to 1X.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to calcium formate, EPA
considered exposure under the
proposed exemption from the
requirement of a tolerance. EPA
assessed dietary exposures from calcium
formate in food as follows:
Because no endpoint was identified
for acute exposure, an acute exposure
assessment was not conducted.
In conducting the chronic dietary
exposure assessment using the Dietary
Exposure Evaluation Model DEEM–
FCIDTM, EPA used 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
VerDate Sep<11>2014
16:14 Dec 03, 2018
Jkt 247001
1994–98. As to residue levels in food,
no residue data were submitted. In the
absence of specific residue data, EPA
has developed an approach which uses
surrogate information to derive upper
bound exposure estimates for the
subject inert ingredient. Upper bound
exposure estimates are based on the
highest tolerance for a given commodity
from a list of high-use insecticides,
herbicides, and fungicides. 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.
In the dietary exposure assessment,
the Agency assumed that the residue
level of the inert ingredient would be no
higher than the highest tolerance for a
given commodity. Implicit in this
assumption is that there would be
similar rates of degradation (if any)
between the active and inert ingredient
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 Agency believes the assumptions
used to estimate dietary exposures lead
to an extremely conservative assessment
of dietary risk due to a series of
compounded conservatisms. First,
assuming that the level of residue for an
inert ingredient is equal to the level of
residue for the active ingredient will
overstate exposure. The concentration of
active ingredients in agricultural
products is generally at least 50 percent
of the product and often can be much
higher. Further, pesticide products
rarely have a single inert ingredient;
rather there is generally a combination
of different inert ingredients used which
additionally reduces the concentration
of any single inert ingredient in the
pesticide product in relation to that of
the active ingredient.
Second, the conservatism of this
methodology is compounded by EPA’s
decision to assume that, for each
commodity, the active ingredient which
will serve as a guide to the potential
level of inert ingredient residues is the
active ingredient with the highest
tolerance level. This assumption
overstates residue values because it
would be highly unlikely, that a single
inert ingredient or class of ingredients
would be present at the level of the
PO 00000
Frm 00029
Fmt 4700
Sfmt 4700
62477
active ingredient in the highest
tolerance for every commodity.
Finally, a third compounding
conservatism is EPA’s assumption that
all foods contain the inert ingredient at
the highest tolerance level. In other
words, EPA assumed 100 percent of all
foods are treated with the inert
ingredient at the rate and manner
necessary to produce the highest residue
legally possible for an active ingredient.
In summary, EPA chose a very
conservative method for estimating
what level of inert residue could be on
food, and then used this methodology to
choose the highest possible residue that
could be found on food and assumed
that all food contained this residue. No
consideration was given to potential
degradation between harvest and
consumption even though monitoring
data shows that tolerance level residues
are typically one to two orders of
magnitude higher than actual residues
in food when distributed in commerce.
Accordingly, although sufficient
information to quantify actual residue
levels in food is not available, the
compounding of these conservative
assumptions will lead to a significant
exaggeration of actual exposures. EPA
does not believe that this approach
underestimates exposure in the absence
of residue data.
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 calcium
formate, 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).
There are no known or anticipated
residential uses for calcium formate and
therefore, residential exposure is not
expected.
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
E:\FR\FM\04DER1.SGM
04DER1
62478
Federal Register / Vol. 83, No. 233 / Tuesday, December 4, 2018 / Rules and Regulations
substances that have a common
mechanism of toxicity.’’
EPA has not found calcium formate to
share a common mechanism of toxicity
with any other substances, and calcium
formate does not appear to produce a
toxic metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that calcium formate does not
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
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 pre-natal
and post-natal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines,
based on reliable data, that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data is available to EPA to support the
choice of a different factor.
EPA has determined that reliable data
show the safety of infants and children
would be adequately protected if the
FQPA SF were reduced to 1X. That
decision is based on the following
findings:
1. Toxicological studies were
identified for calcium formate in the
publicly available databases. However,
calcium formate breaks down into
calcium and formate ions. Calcium ions
are ubiquitous in the natural
environment and can be considered as
having little toxicity or hazard risk. The
toxicological database for calcium
formate is limited. There is available
data on formic acid and related formate
compounds (such as ammonium,
sodium and methyl formate), which can
serve as suitable surrogates for calcium
formate. Studies conducted with
methanol are also applicable to formate
compounds, since methanol is
metabolized into formic acid. Therefore,
the database is considered adequate for
FQPA assessment.
2. There is no evidence of increased
susceptibility of infants and children in
the available reproduction and
developmental toxicity studies with
VerDate Sep<11>2014
16:14 Dec 03, 2018
Jkt 247001
calcium formate and/or sodium formate.
No developmental or maternal systemic
toxicity was observed in rats at doses up
to 200 mg/kg/day when calcium format
was administered via drinking water.
No developmental or maternal toxicity
was observed in mice at doses up to 750
mg/kg gavage dose of sodium formate on
gestation day 8. No evidence of
increased susceptibility was observed
following pre- and post-natal exposure
to calcium formate. In a multigeneration
reproduction study (three to five
generations), no parental, reproductive
or offspring toxicity was observed at
doses up to 200 mg/kg/day.
3. No neurotoxicity studies are
available in the database. However,
there is no evidence of clinical signs of
neurotoxicity in the database, nor
evidence of susceptibility in the young
in the database. Therefore, EPA
concluded that the developmental
neurotoxicity study is not required.
There is no evidence of immunotoxicity
in the available database.
4. The dietary food exposure
assessment utilizes highly conservative
default assumptions that would not
under estimate the dietary risk to all
populations. For the purpose of the
screening level dietary risk assessment
to support this request for an exemption
from the requirement of a tolerance for
ammonium formate, a value of 100 ppb
for drinking water based on screening
level modeling was used for the chronic
dietary risk assessment. The value of
100 ppb is considered to be a high end,
conservative assumption that is not
likely to underestimate drinking water
risks.
Taking into consideration the
available information, EPA concludes
the additional 10X FQPA safety factor
can be reduced to 1X. These
assessments will not underestimate the
exposure and risks posed by calcium
formate.
E. Aggregate Risks and Determination of
Safety
Taking into consideration all available
information on calcium. EPA has
determined that there is a reasonable
certainty that no harm to any population
subgroup will result from aggregate
exposure to calcium formate under
reasonable foreseeable circumstances.
Therefore, the establishment of an
exemption from tolerance under 40 CFR
180.920 for residues of calcium formate
when used as an inert ingredient in
pesticide formulations applied is safe
under FFDCA section 408.
1. Acute risk. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
PO 00000
Frm 00030
Fmt 4700
Sfmt 4700
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, calcium formate is
not expected to pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure analysis, EPA has
concluded that risk estimates for
chronic exposure to calcium formate
from food and water are not of concern
(<100% cPAD with a risk estimate at
31.2% of the cPAD for children 1–2
years old, the population group
receiving the greatest exposure. There
are no residential uses for calcuim
formate.
3. Short-and intermediate term risk.
Short- and intermediate-term
toxicological endpoints were
established; however, calcium formate
is not registered for any use patterns
that would result in short- or
intermediate-term residential exposure.
Short- and intermediate-term risk is
assessed based on short- and
intermediate-term residential exposure
plus chronic dietary exposure. Because
there is no short- or intermediate-term
residential exposure and chronic dietary
exposure has already been assessed
under the appropriately protective
cPAD (which is at least as protective as
the POD used to assess short-term risk),
no further assessment of short- or
intermediate-term risk is necessary, and
EPA relies on the chronic dietary risk
assessment for evaluating short- and
intermediate-term risk for calcium
formate.
4. Aggregate cancer risk U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
calcium formate is not expected to pose
a cancer risk to humans.
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 calcium
formate residues.
V. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is establishing an exemption
from the requirement of a tolerance
without any numerical limitation.
VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.920 for calcium
formate (CAS Reg. No. 544–17–2) when
used as an inert ingredient (carrier) in
pesticide formulations applied to
growing crops only.

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), or Executive Order
13771, entitled ‘‘Reducing Regulations
and Controlling Regulatory Costs’’ (82
FR 9339, February 3, 2017). This action
does not contain any information
collections subject to OMB approval
under the Paperwork Reduction Act
(PRA) (44 U.S.C. 3501 et seq.), nor does
it require any special considerations
under Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the exemption 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).

II. Petition for Exemption
In the Federal Register of April 11, 2018 (83 FR 15528) (FRL-9975-
57), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C.
346a, announcing the filing of a pesticide petition (PP IN-11075) by
ADAMA Agan, Ltd. c/o Makhteshim Agan of North America, Inc., 3120
Highwoods Blvd., Suite 100, Raleigh, NC 27604. The petition requested
that 40 CFR 180.920 be amended by establishing an exemption from the
requirement of a tolerance for residues of calcium formate (CAS Reg.
No. 544-17-2) when used as an inert ingredient (carrier) in pesticide
formulations applied to growing crops only. That document referenced a
summary of the petition prepared by ADAMA Agan, LTD, the petitioner,
which is available in the docket, https://www.regulations.gov.
This is based on the Agency's risk assessment which can be found at
https://www.regulations.gov in document: Calcium Formate; Human Health
Risk Assessment in docket ID number EPA-HQ-OPP-2018-0091. No comments
were received in response to the notice published by EPA.
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
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty
acids; carriers such as clay and
[[Page 62476]]
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 calcium formate including
exposure resulting from the exemption established by this action. EPA's
assessment of exposures and risks associated with calcium formate
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.
The toxicity database on calcium formate is somewhat limited.
Consequently, studies on appropriate surrogates were used to supplement
the database on calcium formate. Formic acid, sodium formate, potassium
formate and ammonium formate were selected as appropriate surrogates
since they are either the acid form of calcium formate or other salts
of formic acid.
Calcium formate is not expected to be acutely toxic based on acute
toxicity data. There are no subchronic or chronic studies on calcium
formate, although there are studies on potassium formate. These studies
show effects based on reduced body weight gain. A two-year study with
potassium formate indicates the compound is not carcinogenic to Wistar
rats.
In mutagenicity studies with calcium formate, sodium formate and
methyl formate, results of the test were negative for all chemicals.
The weight-of-evidence suggests that calcium is not expected to be
mutagenic.
There are no available developmental toxicity studies on calcium
formate; however, both a rat and rabbit developmental toxicity study
have been conducted on sodium formate. In the rat study, the maternal
and developmental no-observed-adverse-effect-level (NOAEL) was
considered the highest dose tested at 945 milligram/kilogram/day (mg/
kg/day). In the rabbit study, the maternal and developmental toxicity
NOAEL was also the highest dose tested at 1,000 mg/kg/day. A five-
generation rat reproductive toxicity study on calcium formate has been
conducted with a NOAEL of >200 mg/kg/day (only dose tested). In a
three-generation reproduction study in rats via drinking water, no
treatment related effects were observed in the parental animals and off
springs at doses up to 200 mg/kg/day.
No studies were submitted for immunotoxicity. However, the toxicity
studies available did not show any signs of immunotoxicity up to limit
doses. Therefore, immunotoxicity is not of concern.
There are no available studies for neurotoxicity. However, the
functional observation battery performed in the 90-day oral toxicity
study did not show any signs of neurotoxicity up to limit doses.
Therefore, neurotoxicity is not of concern.
A metabolism study is available in the toxicity database. Calcium
formate breaks down into calcium and formate ions. Calcium ions are
ubiquitous in the natural environment and can be considered as having
little toxicity or hazard. Formate ions are readily converted to carbon
dioxide in the environment by biodegradation or photooxidation.
Specific information on the studies received and the nature of the
adverse effects caused by calcium formate as well as the NOAEL and the
lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies
can be found at https://www.regulations.gov in the document Calcium
Formate Risk Assessment at page 7 in docket ID number EPA-HQ-OPP-2018-
0091.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a
[[Page 62477]]
complete description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
No toxicological endpoints of concern were identified for calcium
formate based on available toxicity studies on surrogate chemicals.
Formic acid, sodium formate, potassium formate and ammonium formate
were selected as appropriate surrogates since they are either the acid
form of calcium formate or other salts of formic acid. Most of the
available studies on these substances were not conducted up to the
limit dose. The highest dose of 200 mg/kg/day in a lifelong study in
rats via drinking water did not produce any systemic toxicity (IUCLID,
Calcium formate, 2001). Therefore, a conservative risk assessment was
conducted using a NOAEL of 200 mg/kg/day for chronic dietary and short-
and intermediate-term dermal exposure risk estimates. An uncertainty/
safety factor of 100X (10X for interspecies variability and 10X for
interspecies extrapolation) was used. The Food Quality Protection Act
(FQPA) factor of 10X was reduced to 1X, therefore, the chronic
Reference Dose (cRfD) of 2 mg/kg/day is equal to the chronic Population
Adjusted Dose (cPAD). A 100% dermal absorption factor is assumed for
converting oral to dermal equivalent doses in the absence of dermal
toxicity or dermal absorption studies.
For short and intermediate term inhalation exposure, the route
specific study was used. The NOAEL of 0.62 mg/l (32 parts per million
(ppm)) was observed in a 90-day inhalation toxicity study in rats
(IUCLID, Formic acid, 2000). The uncertainty factor is 100X (10X for
interspecies variability and IOX for interspecies extrapolation). The
FQPA factor of 10 X was reduced to 1X.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to calcium formate, EPA considered exposure under the proposed
exemption from the requirement of a tolerance. EPA assessed dietary
exposures from calcium formate in food as follows:
Because no endpoint was identified for acute exposure, an acute
exposure assessment was not conducted.
In conducting the chronic dietary exposure assessment using the
Dietary Exposure Evaluation Model DEEM-FCID\TM\, EPA used 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 1994-
98. As to residue levels in food, no residue data were submitted. In
the absence of specific residue data, EPA has developed an approach
which uses surrogate information to derive upper bound exposure
estimates for the subject inert ingredient. Upper bound exposure
estimates are based on the highest tolerance for a given commodity from
a list of high-use insecticides, herbicides, and fungicides. 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.
In the dietary exposure assessment, the Agency assumed that the
residue level of the inert ingredient would be no higher than the
highest tolerance for a given commodity. Implicit in this assumption is
that there would be similar rates of degradation (if any) between the
active and inert ingredient 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 Agency believes the assumptions used to estimate dietary
exposures lead to an extremely conservative assessment of dietary risk
due to a series of compounded conservatisms. First, assuming that the
level of residue for an inert ingredient is equal to the level of
residue for the active ingredient will overstate exposure. The
concentration of active ingredients in agricultural products is
generally at least 50 percent of the product and often can be much
higher. Further, pesticide products rarely have a single inert
ingredient; rather there is generally a combination of different inert
ingredients used which additionally reduces the concentration of any
single inert ingredient in the pesticide product in relation to that of
the active ingredient.
Second, the conservatism of this methodology is compounded by EPA's
decision to assume that, for each commodity, the active ingredient
which will serve as a guide to the potential level of inert ingredient
residues is the active ingredient with the highest tolerance level.
This assumption overstates residue values because it would be highly
unlikely, that a single inert ingredient or class of ingredients would
be present at the level of the active ingredient in the highest
tolerance for every commodity.
Finally, a third compounding conservatism is EPA's assumption that
all foods contain the inert ingredient at the highest tolerance level.
In other words, EPA assumed 100 percent of all foods are treated with
the inert ingredient at the rate and manner necessary to produce the
highest residue legally possible for an active ingredient.
In summary, EPA chose a very conservative method for estimating
what level of inert residue could be on food, and then used this
methodology to choose the highest possible residue that could be found
on food and assumed that all food contained this residue. No
consideration was given to potential degradation between harvest and
consumption even though monitoring data shows that tolerance level
residues are typically one to two orders of magnitude higher than
actual residues in food when distributed in commerce.
Accordingly, although sufficient information to quantify actual
residue levels in food is not available, the compounding of these
conservative assumptions will lead to a significant exaggeration of
actual exposures. EPA does not believe that this approach
underestimates exposure in the absence of residue data.
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 calcium formate, 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).
There are no known or anticipated residential uses for calcium
formate and therefore, residential exposure is not expected.
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
[[Page 62478]]
substances that have a common mechanism of toxicity.''
EPA has not found calcium formate to share a common mechanism of
toxicity with any other substances, and calcium formate does not appear
to produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
calcium formate does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's website at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
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 pre-natal and post-natal
toxicity and the completeness of the database on toxicity and exposure
unless EPA determines, based on reliable data, that a different margin
of safety will be safe for infants and children. This additional margin
of safety is commonly referred to as the FQPA Safety Factor (SF). In
applying this provision, EPA either retains the default value of 10X,
or uses a different additional safety factor when reliable data is
available to EPA to support the choice of a different factor.
EPA has determined that reliable data show the safety of infants
and children would be adequately protected if the FQPA SF were reduced
to 1X. That decision is based on the following findings:
1. Toxicological studies were identified for calcium formate in the
publicly available databases. However, calcium formate breaks down into
calcium and formate ions. Calcium ions are ubiquitous in the natural
environment and can be considered as having little toxicity or hazard
risk. The toxicological database for calcium formate is limited. There
is available data on formic acid and related formate compounds (such as
ammonium, sodium and methyl formate), which can serve as suitable
surrogates for calcium formate. Studies conducted with methanol are
also applicable to formate compounds, since methanol is metabolized
into formic acid. Therefore, the database is considered adequate for
FQPA assessment.
2. There is no evidence of increased susceptibility of infants and
children in the available reproduction and developmental toxicity
studies with calcium formate and/or sodium formate. No developmental or
maternal systemic toxicity was observed in rats at doses up to 200 mg/
kg/day when calcium format was administered via drinking water. No
developmental or maternal toxicity was observed in mice at doses up to
750 mg/kg gavage dose of sodium formate on gestation day 8. No evidence
of increased susceptibility was observed following pre- and post-natal
exposure to calcium formate. In a multigeneration reproduction study
(three to five generations), no parental, reproductive or offspring
toxicity was observed at doses up to 200 mg/kg/day.
3. No neurotoxicity studies are available in the database. However,
there is no evidence of clinical signs of neurotoxicity in the
database, nor evidence of susceptibility in the young in the database.
Therefore, EPA concluded that the developmental neurotoxicity study is
not required. There is no evidence of immunotoxicity in the available
database.
4. The dietary food exposure assessment utilizes highly
conservative default assumptions that would not under estimate the
dietary risk to all populations. For the purpose of the screening level
dietary risk assessment to support this request for an exemption from
the requirement of a tolerance for ammonium formate, a value of 100 ppb
for drinking water based on screening level modeling was used for the
chronic dietary risk assessment. The value of 100 ppb is considered to
be a high end, conservative assumption that is not likely to
underestimate drinking water risks.
Taking into consideration the available information, EPA concludes
the additional 10X FQPA safety factor can be reduced to 1X. These
assessments will not underestimate the exposure and risks posed by
calcium formate.
E. Aggregate Risks and Determination of Safety
Taking into consideration all available information on calcium. EPA
has determined that there is a reasonable certainty that no harm to any
population subgroup will result from aggregate exposure to calcium
formate under reasonable foreseeable circumstances. Therefore, the
establishment of an exemption from tolerance under 40 CFR 180.920 for
residues of calcium formate when used as an inert ingredient in
pesticide formulations applied is safe under FFDCA section 408.
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,
calcium formate is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure analysis, EPA has concluded that risk
estimates for chronic exposure to calcium formate from food and water
are not of concern (<100% cPAD with a risk estimate at 31.2% of the
cPAD for children 1-2 years old, the population group receiving the
greatest exposure. There are no residential uses for calcuim formate.
3. Short-and intermediate term risk. Short- and intermediate-term
toxicological endpoints were established; however, calcium formate is
not registered for any use patterns that would result in short- or
intermediate-term residential exposure. Short- and intermediate-term
risk is assessed based on short- and intermediate-term residential
exposure plus chronic dietary exposure. Because there is no short- or
intermediate-term residential exposure and chronic dietary exposure has
already been assessed under the appropriately protective cPAD (which is
at least as protective as the POD used to assess short-term risk), no
further assessment of short- or intermediate-term risk is necessary,
and EPA relies on the chronic dietary risk assessment for evaluating
short- and intermediate-term risk for calcium formate.
4. Aggregate cancer risk U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, calcium formate is not expected to pose a cancer risk to
humans.
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 calcium formate residues.
V. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.920 for calcium formate (CAS Reg. No. 544-
17-2) when used as an inert ingredient (carrier) in pesticide
formulations applied to growing crops only.

VII. Statutory and Executive Order Reviews
This action establishes an exemption from the requirement of 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), or Executive Order 13771, entitled ``Reducing
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3,
2017). This action does not contain any information collections subject
to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501
et seq.), nor does it require any special considerations under
Executive Order 12898, entitled ``Federal Actions to Address
Environmental Justice in Minority Populations and Low-Income
Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the exemption 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).
