Pesticide Tolerances for Tefluthrin 



AGENCY: Environmental Protection Agency. 



ACTION: Proposed rule.

+

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

SUMMARY: This document proposes to extend tolerances for the 

combined residues of the synthetic pyrethroid tefluthrin [2,3,5,6-

tetrafluoro-4-methylphenyl)methyl-(1 alpha, 3 alpha)-(Z)-(+/-)-

3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecaboxylate] 

and its metabolite, (Z)-3-(2-chloro-3,3,3-trifluoro-1-propenyl)2,2-

dimethylcyclopropanecaboxylic acid, in or on the raw agricultural 

commodities corn, grain, field, and pop; corn, forage and fodder, 

field and pop. This proposal to extend the effective date for 

tolerances for maximum permissible levels of residues of this 

insecticide in or on these commodities was requested by Zeneca 

Ag Products (previously, ICI Americas, Inc.).

SUPPLEMENTARY INFORMATION: The Agency issued a conditional registration 

for tefluthrin for use on corn, grain, field, and pop; corn, 

forage and fodder, field and pop on January 13, 1989. The registration 

was made conditional with a final expiration date of July 31, 

1993, since certain data were lacking. See the Federal Register 

(FR) of March 8, 1989 (54 FR 9887) for specific data requirements. 

Because of the lack of these data the tolerances were established 

with an expiration date of July 31, 1994. (See the Federal Register 

of February 1, 1989 (54 FR 5080)).



   On January 22, 1990, the Agency issued a Special Data Call-

In Notice to Zeneca Ag Products requiring submission of a simulated 

aquatic field test (mesocosm study) to assess long-term aquatic 

adverse effects related to exposure to this pesticide. This 

data requirement was imposed because of a reported fish kill 

associated with alleged misuse of the product and was added 

to other conditions imposed on the registration in January 1989. 

This study was due by November 30, 1994.

   On October 20 and November 13, 1992, Zeneca Ag Products requested 

an extension of the conditional registration and extension of 

time to November 15, 1994. They also requested a waiver of the 

mesocosm study because of a change in Agency policy on the need 

for higher tiered fate and ecological effects data such as an 

aquatic field study. The Agency reexamined the existing ecological 

effects database and concluded that it had sufficient baseline 

data to characterize aquatic hazard for this pesticide, and 

the Agency waived the requirement for a mesocosm study. However, 

the Agency still concluded that this pesticide may pose aquatic 

risk from use on corn and agreed to an extension of the conditional 

registration until November 15, 1994, provided Zeneca Ag Products 

submit risk reduction measures designed to reduce the potential 

for exposure of aquatic habitats of concern. Zeneca Ag Products 

agreed to these terms, and on June 14, 1993, the Agency extended 

the conditional registration for tefluthrin on corn to November 

15, 1994. By November 15, 1994, the Agency intends to complete 

review of all data and other information submitted and to make 

FIFRA section 3(c)(5) or other appropriate regulatory decisions 

for the corn use of tefluthrin.

   To be consistent with the extensions issued for the conditional 

registrations the Agency is proposing to extend the tolerances 

on corn and other affected commodities. The Agency has determined 

that extending the tolerances will protect the human health. 

Therefore, extensions for the tolerances on corn and other affected 

crops are proposed as set forth below.

   The data submitted in support of these tolerances and other 

relevant material have been reviewed. The toxicological and 

metabolism data and analytical methods for enforcement purposes 

considered in support of these tolerances are discussed in detail 

in related documents published in the Federal Register of February 

1, 1989 (54 FR 5061), for corn.

   Residues remaining in or on the above raw agricultural commodity 

after expiration of these tolerances will not be considered 

actionable if the pesticide is legally applied during the term 

and in accordance with the provisions of the conditional registrations.

   Any person who has registered or submitted an application 

for registration of a pesticide under the Federal Insecticide, 

Fungicide, and Rodenticide Act (FIFRA) as amended, which contains 

any of the ingredients listed herein, may request within 30 

days after publication of this document in the Federal Register 

that this rulemaking proposal be referred to an Advisory Committee 

in accordance with section 408(e) of FIFRA.

   Interested persons are invited to submit written comments 

on the proposed regulation. Comments must bear a notation indicating 

the document control number, (PP 7F3521/P587). All written comments 

filed in response to this petition will be available to the 

Public Response Section, at the address given above, from 9 

a.m. to 4 p.m., Monday through Friday, except legal holidays.

   The Office of Management and Budget has exempted this rule 

from the requirements of Executive Order 12866.

   Pursuant to the requirements of the Regulatory Flexibility 

Act (Pub. L. 96-354, 94 Stat. 1164, 5 U.S.C. 601-612), the Administrator 

has determined that regulations establishing new tolerances 

or food/feed additive regulations or raising tolerance or food/feed 

additive regulation 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).
