II. Petition for Tolerance

    In the Federal Registers of February 28, 2007 (72 FR 9000) (FRL-
8115-5) and February 6, 2008 (73 FR 6964) (FRL-8350-9), EPA issued a
notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3),
announcing the filing of a pesticide petition (PP 6H7114) by Pytech
Chemicals GmbH, 9330 Zionsville Road, Indianapolis, IN 46268 and PP
7E7287 by IR-4, 500 College Road East, Suite 201 W. Princeton, NJ
08540-6635 respectively. The petitions requested that 40 CFR 180.438 be
amended by establishing tolerances for residues of the insecticide
gamma-cyhalothrin, (S)-alpha-cyano-3-phenoxybenzy-(Z)-(1R, 3R)-3-(2-
chloro-3,3,3-trifluoroprop-1-enyl-2,2-dimethycyclopropanecarboxylate,
in all food commodities (other than those already covered by a higher
tolerance as a result of use on growing crops) in food-handling
establishments where food products are held, processed or prepared, at
0.01 parts per million (ppm), pistachio at 0.05 ppm, and okra at 0.20
ppm. These notices referenced a summary of the petitions prepared by
Dow Agro Sciences (on behalf of Pytech Chemicals), which is available
to the public in the docket, http://www.regulations.gov. There were no
comments received in response to the notice of filing.
    The tolerance expression under 40 CFR 180.438(a)(3) currently
identifies the tolerance as a ``food additive'' and also lists specific
instructions for use in food handling establishments under paragraphs,
180.438(a)(3)(ii) thru (v). The term ``food additive tolerance'' is
obsolete since EPA no longer regulates pesticide residues under section
409 of the Federal Food Drug and Cosmetic Act. In addition it is no
longer necessary to identify specific instructions for use in food
handling establishments since these instructions are identified on the
pesticide label. Therefore EPA is revising the tolerance expression
under 40 CFR 180.438(a)(3) to read, ``A tolerance of 0.01 part per
million is established for residues of the insecticide lambda-
cyhalothrin and an isomer gamma-cyhalothrin as follows:'', and is
deleting sections 180.438(a)(3)(ii) thru (v).

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure

[[Page 39263]]

of infants and children to the pesticide chemical residue in
establishing a tolerance and to ``ensure that there is a reasonable
certainty that no harm will result to infants and children from
aggregate exposure to the pesticide chemical residue. . . .''
    Consistent with section 408(b)(2)(D) of FFDCA, and the factors
specified in 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 for the petitioned-for
tolerances for residues of gamma-cyhalothrin on all food commodities
(other than those already covered by a higher tolerance as a result of
use on growing crops) in food-handling establishments where food
products are held, processed or prepared, at 0.01 ppm, pistachio at
0.05 ppm, and okra at 0.20 ppm. EPA's assessment of exposures and risks
associated with establishing tolerances follows.
    Gamma-cyhalothrin is a single, resolved isomer of the pyrethroid
insecticide cyhalothrin. As such, it shares physical, chemical and
biological properties with both cyhalothrin and lambda-cyhalothrin,
which are mixtures of 4 and 2 isomers, respectively. Gamma-cyhalothrin
is the most insecticidally active isomer of cyhalothrin/lambda-
cyhalothrin, and thus the gamma-cyhalothrin technical product is
considered a refined form of cyhalothrin/lambda-cyhalothrin that has
been purified by removal of less-active and inactive isomers.
Therefore, similar levels of insecticidal efficacy for gamma-
cyhalothrin can be obtained with significantly reduced application
rates as compared with either cyhalothrin or lambda-cyhalothrin. EPA
has previously concluded that residue data supporting registered uses
of lambda-cyhalothrin are sufficient to support registration of gamma-
cyhalothrin for the same uses, as long as the use rates of gamma-
cyhalothrin are no greater than half the corresponding use rates of
lambda-cyhalthrin. The proposed application rates of gamma-cyhalthrin
for the requested new uses (considered herein) are no greater than half
of the corresponding, existing application rates for similar registered
uses of lambda-cyhalthrin.
    Tolerances are currently established under 40 CFR 180.438 for
residues of lambda-cyhalothrin in food-handling establishments.Through
the use of bridging data, the toxicology database for gamma-cyhalothrin
is complete using developmental, reproduction, chronic (rodent), and
oncogenicity studies conducted with cyhalothrin and lambda-cyhalothrin.
The nature of the toxic effects caused by lambda-cyhalothrin as well as
gamma-cyhalthrin are discussed in detail in the Federal Register of
September 27, 2002 (67 FR 60902)(FRL-7200-1). Therefore the toxicology
database for gamma-cyhalothrin when bridged with cyhalothrin and
lambda-cyhalothrin are complete for purposes of supporting the proposed
use in food handling establishments.
    In the August 15, 2007 final rule, establishing tolerances for
lambda-cyhalothrin on a number of crops including pistachios. EPA
included residuesat the tolerance level 0.05 ppm in assessing the use
of lambda-cyhalothrin in/on pistachios. Since EPA considered the
pistachio use in this most recent risk assessment establishing the
tolerance on pistachios for gamma-cyhalothrin will not change the
estimated aggregate risks resulting from use of lambda-cyhalothrin as
discussed in the August 15, 2007 (72 FR 45656) Federal Register. Refer
to this Federal Register document available at http://
www.regulations.gov for a detailed discussion of the aggregate risk
assessments and determination of safety.
    A tolerance for residues of lambda-cyhalothrin in okra has not been
established; however, there are adequate residue data for lambda-
cyhalothrin on fruiting vegetables (crop group 8) to support a
tolerance for residues of gamma-cyhalothrin in okra; and EPA included
residues on okra at the fruiting vegetable tolerance level (0.20 ppm)
in the risk assessments supporting the August 15, 2007 final rule
discussed in the previous paragraph. Since EPA considered the okra use
in this most recent assessment establishing the tolerance on okra for
gamma-cyhalothrin will not change the aggregate risks resulting from
use of lambda-cyhalothrin as discussed in the August 15, 2007 (72 FR
45656) Federal Register. Refer to this Federal Register document
available at http://www.regulations.gov for a detailed discussion of
the aggregate risk assessments and determination of safety.
    EPA concludes that the previous risk assessments on lambda-
cyhalothrin sufficiently covers the proposed gamma-cyhalothrin uses and
no new aggregate risk assessment is needed for gamma-cyhalothrin. Based
on the risk assessments discussed in the final rule published in the
Federal Register August 15, 2007 (72 FR 45656, FRL 8143-1) 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 gamma-cyhalothrin residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology, gas chromatography/electron
capture detector (GC/ECD), (ICI Method 81 (PRAM 81)) is available to
enforce the tolerance expression. The method may be requested from:
Chief, Analytical Chemistry Branch, Environmental Science Center, 701
Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905;
e-mail address: residuemethods@epa.gov.

B. International Residue Limits

    There are no established Mexican, Canadian, or Codex MRLs (maximum
residue limits) for gamma-cyhalothrin.

V. Conclusion

    Therefore, tolerances are established for residues of gamma-
cyhalothrin, (S)-alpha-cyano-3-phenoxybenzy-(Z)-(1R, 3R)-3-(2-chloro-
3,3,3-trifluoroprop-1-enyl-2,2-dimethycyclopropanecarboxylate, in or on
all food commodities (other than those already covered by a higher
tolerance as a result of use on growing crops) in food-handling
establishments where food products are held, processed or prepared, at
0.01 ppm, pistachio at 0.05 ppm, and okra at 0.20 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances 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 final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, Actions Concerning Regulations
That Significantly Affect Energy Supply, Distribution, or Use (66 FR
28355, May 22, 2001) or Executive Order 13045, entitled Protection of
Children from Environmental Health Risks and Safety Risks (62 FR 19885,
April 23, 1997). This final rule does not contain any information
collections subject to OMB approval under the Paperwork Reduction Act
(PRA), 44 U.S.C. 3501 et seq., nor does it require any special
considerations under Executive Order 12898, entitled Federal Actions to
Address Environmental Justice in Minority Populations and Low-Income

[[Page 39264]]

Populations (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
    This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR 43255,
August 10, 1999) and Executive Order 13175, entitled Consultation
and Coordination with Indian Tribal Governments (59 FR 22951,
November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
    This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement Act
of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note).

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
