ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 180
[EPA-HQ-OPP-2006-0582; FRL-8082-1]
Isophorone; Exemption from the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation amends existing exemption from the requirement
of a tolerance for residues of isophorone (CAS Reg. No. 78-59-1) to
limit the use to beets, ginseng, rice, spinach, sugar beets, and Swiss
chard. The Isophorone Task Group (ITG) requested this revised exemption
from the requirement of a tolerance under the Federal Food, Drug, and
Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act
(FQPA) of 1996. This regulatory action contributes toward the Agency's
tolerance reassessment requirements under FFDCA section 408(q), as
amended by the FQPA of 1996. By law, EPA is required by August 2006 to
reassess the tolerances that were in existence on August 2, 1996. The
regulatory action in this document pertains to the revision of one
existing tolerance exemption which is counted as a tolerance
reassessment toward the August 2006 review deadline.
DATES: This regulation is effective August 9, 2006. Objections and
requests for hearings must be received on or before October 10, 2006,
and must be filed in accordance with the instructions provided in 40
CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings
In the Federal Register of April 27, 2005 (70 FR 7951) (FRL-7710-
1), EPA
[[Page 45404]]
issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a pesticide petition (PP 4E6894)
The Isophorone Task Group (ITG) of the Ketones Panel of the American
Chemistry Council, 1300 Wilson Blvd., Arlington, VA 22209. The petition
requested that 40 CFR 180.920 be amended by limiting the existing
exemption from the requirement for isophorone (CAS Reg. No. 78-59-1) to
rice, spinach, and sugar beets. That notice included a summary of the
pesticide petition prepared by ITG, the petitioner. Comments were
received on the notice of filing. EPA's response to these comments is
discussed in Unit IV.
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm
.
III. Aggregate Risk Assessment and Determination of Safety
Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other relevant information in support of
this action. EPA has sufficient data to assess the hazards of and to
make a determination on aggregate exposure, consistent with section
408(b)(2) of FFDCA, for an exemption from the requirement of a
tolerance for residues of isophorone in or on beets, ginseng, rice,
spinach, sugar beets, and Swiss chard. EPA's assessment of exposures
and risks associated with establishing the tolerance follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children. The nature of the toxic effects caused by isophorone are
discussed in the following Table 1 as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the reviewed toxicity studies.

Isophorone was evaluated as part of the International Programme on
Chemical Safety (ICPS). The IPCS is a joint venture of the United
Nations Environment Programme, the International Labour Organisation,
and the World Health Organization. The main objective of the IPCS is to
carry out and disseminate evaluations of the effects of chemicals on
human health and the quality of the environment.
The ICPS Environmental Health Criteria monograph for isophorone
critically evaluated the available toxicity data on isophorone, which
included a consideration of the studies summarized in Table 1 as well
as other available toxicity data on isophorone. As part of the human
health risk assessment of isophorone, the ICPS monograph states that
``limited studies in rats and mice indicate that isophorone does not
affect fertility nor does it cause developmental toxicity in
experimental animals.'' Additionally in summarizing the results of
genotoxicity testing, the ICPS further concluded that ``the weight of
evidence of all mutagenicity data supports the contention that
isophorone is not a potent DNA-reactive compound.''
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the NOAEL from the toxicology study identified as
appropriate for use in risk assessment is used to estimate the
toxicological level of concern (LOC). However, the LOAEL are identified
is sometimes used for risk assessment if no NOAEL was achieved in the
toxicology study selected. An uncertainty factor (UF) is applied to
reflect uncertainties inherent in the extrapolation from laboratory
animal data to humans and in the variations in sensitivity among
members of the human population as well as other unknowns.
The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify non-threshold hazards such as
cancer. The Q* approach assumes that any amount of exposure will lead
to some degree of cancer risk, estimates risk in terms of the
probability of occurrence of additional cancer cases.
A summary of the toxicological endpoints for isophorone used for
human risk assessment is shown in the following Table 2:

Classification: Under the 1986 cancer classification scheme, isophorone
was classified as Group C- Possible Human Carcinogen, with a linear low-
dose extrapolation approach and a 3/4s interspecies scaling factor for
human risk. The upper bound estimate of unit risk, Q1* is 6.08 x 10-4 in
human equivalents
----------------------------------------------------------------------------------------------------------------
C. Exposure Assessment
1. Dietary exposure from food and feed uses. An exemption from the
requirement of a tolerances has been established (40 CFR 180.40 CFR
site) for the residues of isophorone, in or on beet, ginseng, rice,
spinach, sugar beet and Swiss chard commodities. Risk assessments were
conducted by EPA to assess dietary exposures from isophorone in food as
follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure.
Option 1. No such effects were identified in the toxicological
studies for isophorone; therefore, a quantitative acute dietary
exposure assessment is unnecessary.
ii. Chronic exposure.--Option 2. In conducting the chronic dietary
exposure assessment EPA used the Dietary Exposure Evaluation Model
software with the Food Commodity Intake Database (DEEM-
FCIDTM), which incorporates food consumption data as
reported by respondents in the United States Department of Agriculture
(USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake
by Individuals (CSFII), and accumulated exposure to the chemical for
each commodity. The following assumptions were made for the chronic
exposure assessments: The assessment was based on a screening level
dietary assessment that assumed residues of isophorone in beet,
ginseng, rice, spinach, sugar beet and Swiss chard commodities
corresponding to the highest established active ingredient tolerance
level residues for those commodities and 100% crop treated. The highest
established tolerance level active ingredient residue level is chosen
as ``worst-case'' chronic exposure scenario as it would be highly
unlikely that residues of isophorone in the above-listed crops would be
at such levels.
iii. Cancer. The assessment assumed residues of isophorone in beet,
ginseng, rice, spinach, sugar beet and Swiss chard commodities
corresponding to the highest established active ingredient tolerance
level residues for those commodities and 100% crop treated. The highest
established tolerance level active ingredient residue level is chosen
as ``worst-case'' cancer exposure scenario as it would be highly
unlikely that residues of isophorone in the above-listed crops would be
at such levels.
2. Dietary exposure from drinking water. Monitoring exposure data
are utilized to complete a dietary exposure
[[Page 45406]]
analysis and risk assessment for isophorone in drinking water. The
estimated drinking water concentration (EDWC) of isophorone of 10
[mu]g/L utilized for the purposes of this tolerance action is a value
equivalent to the highest measured concentration of isophorone in
drinking water sources in monitoring studies used by EPA to establish
ambient water quality criteria for isophorone. (EPA 440/5-80-056; NTIS
PB81-11767).
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets).
Since the use of isophorone is limited to pesticide productswhich
are not registered for use on any sites that would result in
residential exposure, no residential exposures are expected and a
residential exposure assessment has not been conducted
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to isophorone and any other
substances and isophorone does not appear to produce a toxic metabolite
produced by other substances. For the purposes of this tolerance
action, therefore, EPA has not assumed that isophorone has a common
mechanism of toxicity with other substances. For information regarding
EPA's efforts to determine which chemicals have a common mechanism of
toxicity and to evaluate the cumulative effects of such chemicals, see
the policy statements released by EPA's Office of Pesticide Programs
concerning common mechanism determinations and procedures for
cumulating effects from substances found to have a common mechanism on
EPA's website at http://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional tenfold margin of safety for infants and children in the
case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the data base on toxicity and exposure
unless EPA determines based on reliable data that a different margin of
safety will be safe for infants and children. Margins of safety are
incorporated into EPA risk assessments either directly through use of a
MOE analysis or through using uncertainty (safety) factors in
calculating a dose level that poses no appreciable risk to humans. In
applying this provision, EPA either retains the default value of 10X
when reliable data do not support the choice of a different factor, or,
if reliable data are available, EPA uses a different additional safety
factor value based on the use of traditional uncertainty factors and/or
special FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. There was no evidence of
increased prenatal or postnatal susceptibility of isophorone following
in utero exposure to rats and mice.
3. Conclusion. There is an adequate toxicity database for the
selection of doses and endpoints for use in risk assessment for
isophorone. Exposure data are complete or are estimated based on data
that reasonably account for potential exposures. The use of the IRIS
chronic reference dose (cRfD) utilizes an additional 10X UF beyond the
traditional UFs for intraspecies variability and interspecies
extrapolation of 100X . This is protective of any potential concerns
for increased susceptibility of infants and children to isophorone. The
additional 10X uncertainty factor incorporated into the IRIS RfD is
based on the use of a subchronic toxicity study, which, given the lack
of increased pre-natal and postnatal susceptibility of isophorone,
would address any potential concerns for increased susceptibility of
infants and children to isophorone, therefore the FQPA factor is
removed.
E. Aggregate Risks and Determination of Safety
1. Acute risk. As there were no toxic effects attributable to a
single dose, an endpoint of concern was not identified to quantitate
acute dietary risk to the general population or to the subpopulation
females 13-50 years old. No acute risk is expected from exposure to
isophorone
2. Chronic risk. The chronic dietary exposure analysis is based on
a screening level dietary assessment that assumed residues of
isophorone in beets, ginseng, rice, spinach, sugar beet and Swiss chard
commodities corresponding to the highest established active ingredient
tolerance level residues for those commodities and 100% crop treated
Even with these highly conservative assumptions, the risk estimates are
well below the Agency's level of concern. Using the exposure
assumptions described in this unit for chronic exposure, EPA has
concluded that exposure to isophorone from food and drinking water will
utilize 1.8% of the chronic population adjusted dose (cPAD) for the
U.S. population, and 4.4% of the cPAD for non-nursing infants, the most
highly exposed population subgroup. Based on the use pattern, chronic
residential exposure to residues of isophorone is not expected.
Drinking water was incorporated directly into the dietary assessment
using the concentration for drinking water given in unit III.C.2.
3. Aggregate cancer risk for U.S. population. A non-threshold
(Q1*) approach is used to estimate estimate cancer risk. The
upper bound estimate of lifetime cancer risk for the U.S population is
2.14 x 10-6. This value is derived by multiplying the upper
bound estimate of unit risk, 6.08 x 10-4 by the chronic
dietary exposure (food + drinking water) for the U.S. general
population (0.003520 mg/kg/day). Drinking water was incorporated
directly into the dietary assessment using the concentration for
drinking water given in unit III.C.2. Since this upper bound estimate
of cancer risk is based on a very conservative exposure estimate, and
is within the range of one in one million cancer risk that is typically
considered to not be a concern. EPA therefore concludes that isophorone
is not expected to pose a carcinogenic risk to humans. If applicable,
insert text. There is no boilerplate for this section.
4. 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, and to infants and children from aggregate
exposure to isophorone residues.
IV. Other Considerations
A. 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.
B. International Residue Limits
There are currently no Codex Maximum Residue Limits for isophorone
[[Page 45407]]
C. Response to Comments
Ten comments were received regarding petition PP 4E6894. One
comment, from B. Sachau, regarded general opposition to Agency approval
of tolerances and exemptions other than zero, and general opposition to
any residue left on a treated crop. The Agency finds that this comment
contained no scientific data or evidence to rebut the Agency's
conclusion that there is a reasonable certainty that no harm will
result from aggregate exposure to isophorone including all anticipated
dietary exposures and other exposures for which there is reliable
information. This comment, as well as prior similar comments from B.
Sachau have been responded to by the Agency on several occasions. For
example, (October 29, 2004, 69 FR 63083), (January 7, 2005, 70 FR
1349), and (June 30, 2005, 70 FR 37683. The other nine comments
regarded the use of isophorone in desmedipham and phenmedipham
formulations for use on beets, Swiss chard and ginseng. These uses are
either part of existing section 24(c) registrations or section 18
emergency exemptions, with each of the commentors requesting that these
commodities be included in the reassessment of the isophorone tolerance
exemption. The Agency agrees that these commodities should be included
in the tolerance exemption expression for isophorone and has included
these commodities in the aggregrate risk assessment and safety
determination provided in Unit III.
V. Conclusion
Therefore, an exemption from the requirement of a tolerance is
established for residues of the inert ingredient isophorone, in or on
beets, ginseng, rice, spinach, sugar beets, and Swiss chard.
VI. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this rule has been
exempted from review under Executive Order 12866 due to its lack of
significance, this rule is not subject to Executive Order 13211,
Actions Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May 22, 2001). This final rule does
not contain any information collections subject to OMB approval under
the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., or impose
any enforceable duty or contain any unfunded mandate as described under
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law
104-4). 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), or OMB review or any Agency action under Executive
Order 13045, entitled Protection of Children from Environmental Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). This action does
not involve any technical standards that would require Agency
consideration of voluntary consensus standards pursuant to section
12(d) of the National Technology Transfer and Advancement Act of 1995
(NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since
tolerances and exemptions that are established on the basis of a
petition under section 408(d) of FFDCA, such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply In addition, the Agency has determined that this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, entitled Federalism
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to
develop an accountable process to ensure ``meaningful and timely input
by State and local officials in the development of regulatory policies
that have federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. This action
does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. For these same reasons, the Agency has
determined that this rule does not have any ``tribal implications'' as
described in Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000). Executive Order 13175, requires EPA to develop an accountable
process to ensure ``meaningful and timely input by tribal officials in
the development of regulatory policies that have tribal implications.''
``Policies that have tribal implications'' is defined in the Executive
order to include regulations that have ``substantial direct effects on
one or more Indian tribes, on the relationship between the Federal
Government and the Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.''
This rule will not have substantial direct effects on tribal
governments, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this rule.
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of this final rule in the Federal Register. This final
rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
