40 CFR Part 180

[EPA-HQ-OPP-2009-0540; FRL-8808-4]


Hexythiazox; Pesticide Tolerances for Emergency Exemptions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes time-limited tolerances for 
combined residues of hexythiazox in or on corn, sweet, plus cobs with 
husks removed (K+CWHR); corn, sweet, forage; and corn, sweet, stover. 
This action is in response to EPA's granting of an emergency exemption 
under section 18 of the Federal Insecticide, Fungicide, and Rodenticide 
Act (FIFRA) authorizing use of the pesticide on sweet corn grown for 
seed. This regulation establishes a maximum permissible level for 
residues of hexythiazox in these food . The time-limited tolerances 
expire and are revoked on December 31, 2012.

DATES: This regulation is effective February 3, 2010. Objections and 
requests for hearings must be received on or before April 5, 2010, 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

    EPA, on its own initiative, in accordance with sections 408(e) and 
408(l)(6) of FFDCA, 21 U.S.C. 346a(e) and 346a(1)(6), is establishing 
time-limited tolerances for the combined residues of hexythiazox, 
trans-5-(4-chlorophenyl)-N-cyclohexyl-4-methyl-2-oxothiazolidine-3-
carboxamide and its metabolites containing the (4-

[[Page 5516]]

chlorophenyl)-4-methyl-2-oxo-3-thiazolidine moiety, in or on corn, 
sweet, plus cobs with husks removed (K+CWHR) at 0.02 parts per million 
(ppm); corn, sweet, forage at 6.0 ppm; and corn, sweet, stover at 2.5 
ppm. These time-limited tolerances expire and are revoked on December 
31, 2012. EPA will publish a document in the Federal Register to remove 
the revoked tolerances from the Code of Federal Regulations (CFR).
    Section 408(l)(6) of FFDCA requires EPA to establish a time-limited 
tolerance or exemption from the requirement for a tolerance for 
pesticide chemical residues in food that will result from the use of a 
pesticide under an emergency exemption granted by EPA under section 18 
of FIFRA. Such tolerances can be established without providing notice 
or period for public comment. EPA does not intend for its actions on 
FIFRA section 18 related time-limited tolerances to set binding 
precedents for the application of section 408 of FFDCA and the new 
safety standard to other tolerances and exemptions. Section 408(e) of 
FFDCA allows EPA to establish a tolerance or an exemption from the 
requirement of a tolerance on its own initiative, i.e., without having 
received any petition from an outside party.
    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. . . 
.''
    Section 18 of FIFRA authorizes EPA to exempt any Federal or State 
agency from any provision of FIFRA, if EPA determines that ``emergency 
conditions exist which require such exemption.'' EPA has established 
regulations governing such emergency exemptions in 40 CFR part 166.

III. Emergency Exemption for Hexythiazox on Sweet Corn Grown for Seed 
and FFDCA Tolerances

    The applicant, the Idaho Department of Agriculture, states that 
there has been an increase in mite populations over the past several 
years and growers currently have no feasible control alternative 
(either chemical or non-chemical) to control them. Left unchecked, 
mites can cause significant losses in seed yield and quality. After 
having reviewed the submission, EPA determined that emergency 
conditions exist for this State, and that the criteria for an emergency 
exemption are met. EPA has authorized under FIFRA section 18 the use of 
hexythiazox on sweet corn grown for seed for control of mites in Idaho.
    As part of its evaluation of the emergency exemption application, 
EPA assessed the potential risks presented by residues of hexythiazox 
in or on sweet corn plus cobs with husks removed (K+CWHR), sweet corn 
forage, and sweet corn stover. In doing so, EPA considered the safety 
standard in section 408(b)(2) of FFDCA, and EPA decided that the 
necessary tolerance under section 408(l)(6) of FFDCA would be 
consistent with the safety standard and with FIFRA section 18. 
Consistent with the need to move quickly on the emergency exemption in 
order to address an urgent non-routine situation and to ensure that the 
resulting food is safe and lawful, EPA is issuing this tolerance 
without notice and opportunity for public comment as provided in 
section 408(l)(6) of FFDCA. Although these time-limited tolerances 
expire and are revoked on December 31, 2012, under section 408(l)(5) of 
FFDCA, residues of the pesticide not in excess of the amounts specified 
in the tolerance remaining in or on sweet corn plus cobs with husks 
removed (K+CWHR), sweet corn forage, and sweet corn stover after that 
date will not be unlawful, provided the pesticide was applied in a 
manner that was lawful under FIFRA, and the residues do not exceed a 
level that was authorized by these time-limited tolerances at the time 
of that application. EPA will take action to revoke these time-limited 
tolerances earlier if any experience with, scientific data on, or other 
relevant information on this pesticide indicate that the residues are 
not safe.
    Because these time-limited tolerances are being approved under 
emergency conditions, EPA has not made any decisions about whether 
hexythiazox meets FIFRA's registration requirements for use on sweet 
corn grown for seed or whether permanent tolerances for this use would 
be appropriate. Under these circumstances, EPA does not believe that 
this time-limited tolerance decision serves as a basis for registration 
of hexythiazox by a State for special local needs under FIFRA section 
24(c). Nor does this tolerance serve as the basis for persons in any 
State other than Idaho to use this pesticide on these crops under FIFRA 
section 18 absent the issuance of an emergency exemption applicable 
within that State. For additional information regarding the emergency 
exemption for hexythiazox, contact the Agency's Registration Division 
at the address provided under FOR FURTHER INFORMATION CONTACT.

IV. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.''
    Consistent with the factors specified in FFDCA section 
408(b)(2)(D), EPA has reviewed the available scientific data and other 
relevant information in support of this action. EPA has sufficient data 
to assess the hazards of and to make a determination on aggregate 
exposure expected as a result of this emergency exemption request and 
the time-limited tolerances for combined residues of hexythiazox, 
trans-5-(4-chlorophenyl)-N-cyclohexyl-4-methyl-2-oxothiazolidine-3-
carboxamide and its metabolites containing the (4-chlorophenyl)-4-
methyl-2-oxo-3-thiazolidine moiety, in or on corn, sweet, plus cobs 
with husks removed (K+CWHR) at 0.02 ppm; corn, sweet, forage at 6.0 
ppm; and corn, sweet, stover at 2.5 ppm. EPA's assessment of exposures 
and risks associated with establishing time-limited tolerances follows.
    On December 2, 2009 the Agency published a Final Rule (74 FR 63070,

[[Page 5517]]

FRL-8799-9) establishing tolerances for combined residues of 
hexythiazox in or on potato at 0.02 ppm. When the Agency conducted the 
risk assessments in support of the December 2, 2009 tolerance action, 
it also assessed the risk resulting from the section 18 use on sweet 
corn grown for seed. Specifically, in that risk assessment, EPA assumed 
that hexythiazox would be present in corn, sweet, plus cobs with husks 
removed (K+CWHR) at 0.02 ppm; corn, sweet, forage at 6.0 ppm; and corn, 
sweet, stover at 2.5 ppm. EPA relies upon those risk assessments and 
the findings made in the Federal Register document in support of this 
action. Refer to the December 2, 2009 Federal Register document (EPA-
HQ-OPP-2007-0330), available at http://www.regulations.gov, for a 
detailed discussion of the aggregate risk assessments and determination 
of safety.
    Based on the risk assessments discussed in the final rule published 
in the Federal Register of December 2, 2009 (74 FR 63070, FRL-8799-9), 
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 hexythiazox residues.

V. Other Considerations

A. Analytical Enforcement Methodology

    An adequate enforcement methodology (Method AMR-985-87) 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 currently established CODEX, Canadian, or Mexican MRLs 
for residues of hexythiazox in/on the subject commodities.

VI. Conclusion

    Therefore, time-limited tolerances are established for combined 
residues of hexythiazox, trans-5-(4-chlorophenyl)-N-cyclohexyl-4-
methyl-2-oxothiazolidine-3-carboxamide and its metabolites containing 
the (4-chlorophenyl)-4-methyl-2-oxo-3-thiazolidine moiety, in or on 
corn, sweet, plus cobs with husks removed (K+CWHR) at 0.02 ppm; corn, 
sweet, forage at 6.0 ppm; and corn, sweet, stover at 2.5 ppm. These 
tolerances expire and are revoked on December 31, 2012.

VII. Statutory and Executive Order Reviews

    This final rule establishes tolerances under sections 408(e) and 
408(l)(6) 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, 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 final rule does 
not contain any information collections subject to OMB approval under 
the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it 
require any special considerations under Executive Order 12898, 
entitled Federal Actions to Address Environmental Justice in Minority 
Populations and Low-Income Populations (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established in accordance 
with sections 408(e) and 408(l)(6) of FFDCA, such as the tolerances in 
this final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.) do not apply.
    This final rule directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of FFDCA. As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled Federalism (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
Consultation and Coordination with Indian Tribal Governments (65 FR 
67249, November 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).

VIII. 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).
