Tefluthrin; Renewal of Time-limited Tolerances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This rule establishes a tolerance for the combined residues of 
the pyrethroid tefluthrin and its metabolites in or on the raw 
agricultural commodity (RAC) corn, fresh (including sweet K + CWHR) at 
0.06 parts per million (ppm), and corn, forage and fodder, sweet at 
0.06 ppm and renews time-limited tolerances for tefluthrin on the RAC's 
corn, grain, field, and pop; corn forage and fodder, field and pop. 
These regulations to establish maximum permissible levels for residues 
of the chemical and renew tolerances were requested in a petition 
submitted by Zeneca Ag Products.

SUPPLEMENTARY INFORMATION: EPA issued a notice published in the Federal 
Register of February 8, 1995 (60 FR 7540)(FRL-4926-4), which announced 
that Zeneca Ag Products had submitted pesticide petition (PP) 4F4406 to 
EPA requesting that the Administrator, pursuant to section 408(d) of 
the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d ), 
establish a tolerance for the combined residues of the insecticide 
tefluthrin (2,3,5,6-tetrafluro-4-methylphenyl)methyl-(1 alpha, 3 
alpha)-(Z)-( )-3(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-
dimethylcyclopropanecarboxylate) and its metabolite (Z)-3-(2-chloro-
3,3,3-trifluroro-1-propenyl)-2,2-dimethylcyclopropanecarboxylic acid, 
in or on the raw agricultural commodity corn, fresh (including sweet K 
+ CWHR) at 0.06 ppm, and corn, forage and fodder, sweet at 0.06 parts 
per million (ppm).
    No comments were received in response to the notice of filing.
    The scientific data submitted in the petition and other relevant 
material have been evaluated. The toxicological and metabolism data 
considered in support of the tolerance are discussed in detail in 
related documents published in the Federal Register of February 1, 1989 
(54 FR 5080).
    A dietary exposure/risk assessment was performed for teflutrhin on 
sweet corn using a Reference Dose (RfD) of 0.005 mg/kg/day, based on a 
no-observed-effect-level (NOEL) of 0.5 mg/kg bwt/day from a 1- year dog 
feeding study with an uncertainty factor of 100. The endpoint of 
concern was increased incidence of ataxia. The Theoretical Maximum 
Residue Contribution (TMRC) from established tolerances utilizes 0.41% 
of the RfD for the U. S. population or 0.69% of the RfD if the new 
tolerance is granted. Established tolerances utilize 1.06% of the RfD 
for nonnursing infants less than 1 year old, the subgroup with the 
highest estimated exposure to tefluthrin residues or 1.71% of the RfD 
if the new tolerance is granted.
    Generally speaking, EPA has no cause for concern if total residue 
contribution for published and final tolerances is less than the RfD.
    The nature of tefluthrin residue in plants and animals for this 
corn use is adequately understood. The residues of concern is 
tefluthrin and its metabolite. There is no reasonable expectation of 
secondary residues in animal tissues and milk from the use as 
delineated in 40 CFR 180.6(a)(3). An adequate analytical method, gas 
liquid chromatography with an electron capture detector, is available 
for enforcement purposes. The enforcement methodology has been 
submitted to the Food and Drug Administration, and is published in the 
Pesticide Analytical Manual Vol. II (PAM II).
    In the Federal Register of September 30, 1994 (59 FR 49824) EPA 
amended 40 CFR 180.440 by extending to November 15, 1995 tolerances of 
0.06 ppm for residues of tefluthrin in or on field and pop, corn grain 
including, forage and fodder. The tolerances were extedned to coincide 
with the extension of the conditional registration of this pesticide to 
allow time for EPA to review data and complete an aquatic risk 
assessment for use on field and pop corn. The basis for the extension 
is discussed in detail in the above Federal Register notice. On 
November 14, 1995 EPA again amended the conditional

[[Page 19853]]

registration of this pesticide on field and pop corn by extending the 
expiration date to November 15, 1996. The registration was amended and 
extended for an additional year to allow time for submission and 
evaluation of additional data/information on aquatic risk mitigation, 
specifically, surface-water runoff data. Zeneca Ag Products submitted 
this information on December 1, 1995.
    To be consistent with the extension issued for the conditional 
registration the Agency is renewing the tolerances on field and pop 
corn grains, including their forage and fodder, with an expiration date 
of November 15, 1997 to cover residues expected to result from use 
during the period of conditional registration.
    With respect to the additional use of tefluthrin on sweet corn, the 
Agency concluded that this additional use would not cause a significant 
increase in the risk of adverse effects to the environment. This 
conclusion was premised mainly on the following:
    1. The directions for use and precautions for use of tefluthrin on 
sweet corn are identical to the current directions for use for 
tefluthrin on field and pop corn.
    2. Current, interim aquatic risk mitigation measures approved for 
use on field and pop corn will also be used for application on sweet 
corn.
    To be consistent with the conditional registration and renewal on 
field and pop corn the Agency is issuing a conditional registration 
with an expiration date of November 15, 1996 and establishing a time-
limited tolerance on sweet corn and its forage and fodder with an 
expiration date of November 15, 1997 to cover residues expected to 
result from use during the period of conditioanl registration.
    Upon evaluation of the additional data/information required as a 
condition of the registration for this insecticide on corn the Agency 
will reassess the tolerances and the registration, and if appropriate, 
will issue permanent tolerances and an unconditional registration for 
the insecticide on corn.
    Residues remaining in or on the above commodities after expiration 
of these tolerances will not be considered actionable if the pesticide 
is legally applied during the term of and in accordance with the 
provisions of the conditional registration.
    There are presently no actions pending against the continued 
registration of this chemical.
    Based on the information and data considered, the Agency has 
determined that the tolerance established by amending 40 CFR part 180 
will protect the public health. Therefore, the tolerance is established 
as set forth below.
    Any person adversely affected by this regulation may, within 30 
days after publication of this document in the Federal Register, file 
written objections to the regulation and may also request a hearing on 
those objections. Objections and hearing requests must be filed with 
the Hearing Clerk, at the address given above (40 CFR 178.20). A copy 
of the objections and/or hearing requests filed with the Hearing Clerk 
should be submitted to the OPP docket for this rulemaking. The 
objections submitted must specify the provisions of the regulation 
deemed objectionable and the grounds for the objections (40 CFR 
178.25). Each objection must be accompanied by the fee prescribed by 40 
CFR 180.33(i). If a hearing is requested, the objections must include a 
statement of the factual issue(s) on which a hearing is requested, the 
requestor's contentions on such issues, and a summary of any evidence 
relied upon by the objector (40 CFR 178.27). A request for a hearing 
will be granted if the Administrator determines that the material 
submitted shows the following: There is genuine and substantial issue 
of fact; there is a reasonable possibility that available evidence 
identified by the requestor would, if established, resolve one or more 
of such issues in favor of the requestor, taking into account 
uncontested claims or facts to the contrary; and resolution of the 
factual issue(s) in the manner sought by the requestor would be 
adequate to justify the action requested (40 CFR 178.32).
    A record has been established for this rulemaking under the docket 
number [PP 4F4406/R2222] (including any comments and data submitted 
electronically). A public version of this record, including printed, 
paper versions of electronic comments, which does not include any 
information claimed as CBI, is available for inspection from 8 a.m. to 
4:30 p.m., Monday through Friday, excluding legal holidays. The public 
record is located in Room 1132 of the Public Response and Program 
Resources Branch, Field Operations Division (7506C), Office of 
Pesticide Programs, Environmental Protection Agency, Crystal Mall #2, 
1921 Jefferson Davis Highway, Arlington, VA.
    The official record for this rulemaking, as well as the public 
version, as described above will be kept in paper form. Accordingly, 
EPA will transfer any copies of objections and hearing requests 
received electronically into printed, paper form as they are received 
and will place the paper copies in the official rule-making record 
which will also include all comments submitted directly in writing. The 
official rulemaking record is the paper record maintained at the 
address in ``ADDRESSES'' at the beginning of this document.
    Under Executive Order 12866 (58 FR 51735, October 4, 1993), the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to all the requirements of the Executive Order 
(i.e., Regulatory Impact Analysis, review by the Office of Management 
and Budget (OMB)). Under section 3(f), the order defines 
``significant'' as those actions likely to lead to a rule (1) having an 
annual effect on the economy of $100 million or more, or adversely and 
materially affecting a sector of the economy, productivity, 
competition, jobs, the environment, public health or safety, or State, 
local or tribal governments or communities (also known as 
``economically significant''); (2) creating serious inconsistency or 
otherwise interfering with an action taken or planned by another 
agency; (3) materially altering the budgetary impacts of entitlement, 
grants, user fees, or loan programs; or (4) raising novel legal or 
policy issues arising out of legal mandates, the President's 
priorities, or the principles set forth in this Executive Order.
    Pursuant to the terms of this Executive Order, EPA has determined 
that this rule is not ``significant'' and is therefore not subject to 
OMB review.
    Pursuant to the requirements of the Regulatory Flexibility Act 
(Pub. L. 9-354, 94 Stat. 1164, 5 U.S.C. 601-612), the Administrator has 
determined that regulations establishing new tolerances or raising 
tolerance levels or establishing exemptions from tolerance requirements 
do not have a significant economic impact on a substantial number of 
small entities. A certification statement to this effect was published 
in the Federal Register of May 4, 1981 (46 FR 24950).
    In addition, this action does not impose any enforceable duty, or 
contain any ``unfunded mandates'' as described in Title II of the 
Unfunded Mandates Reform Act of 1995 (P.L. 104-4), or require prior 
consultation as specified by Executive Order 12875 (58 FR 58093, 
October 28, 1993), entitled Enhancing the Intergovenmental Partnership, 
or special considerations as required by Executive Order 12898 (59 FR 
7629, February 16, 1994).
