AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

SUMMARY: This notice announces Agency approval of applications submitted by Ciba-Geigy Corporation, to conditionally register the pesticide products Peak, Exceed, and Prosulfuron Technical containing new active ingredients not included in any previously registered products pursuant to the provisions of section 3(c)(7)(C) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended.

FOR FURTHER INFORMATION CONTACT: By mail: Robert Taylor, Product Manager (PM) 25, Registration Division (7505C), Office of Pesticide Programs, 401 M St., SW., Washington, DC 20460. Office location and telephone number: Rm. 245, CM #2, Environmental Protection Agency, 1921 Jefferson Davis Hwy, Arlington, VA 22202, 703-305-6800; e-mail: taylor.robert@epamail.epa.gov.

SUPPLEMENTARY INFORMATION: EPA issued a notice, published in the Federal Register of August 18, 1994 (59 FR 42593), which announced that Ciba-Geigy Corp., P.O. Box 18300, Greensboro, NC, 27419, had submitted applications to conditionally register the pesticide products Exceed WG (now known as Peak) and Prosulfuron Technical (EPA File Symbols 100-TAG and 100-TAE), containing the active ingredient prosulfuron 1-(4- methoxy-6-methyl-triazin-2-yl)-3-[2-(3,3,3-trifluoropropyl)- phenylsulfonyl]-urea at 57 and 96 percent respectively, an active ingredient not included in any previously registered products. EPA subsequently received an application from Ciba-Geigy to register the product Exceed (EPA File Symbol 100-TTU), containing the active ingredient prosulfuron 1-(4-methoxy-6-methyl-triazin-2-yl)-3-[2- (3,3,3-trifluoropropyl)-phenylsulfonyl]-urea at 32.3 percent, an active ingredient not included in any previously registered products and primisulfuron-methyl 3-[4,6-bis(difluoromethoxy)-pyrimidin-2-yl]-1-(2- methoxycarbonylphenylsulfonyl) urea also at 32.3 percent, an active ingredient that was registered in 1990, for use in other products. However, since the notice of receipt of application was not published in Federal Register, as required by FIFRA, as amended, interested parties may submit written comments within 30 days from the date of publication of this notice for this product only. Comments and data may also be submitted electronically by sending electronic mail; e-mail to: opp-docket@epamail.epa.gov. More detailed information is found in all documents requesting comments as of May 1995. The applications were approved on May 3, 1995, for one technical and two end-use products listed below:

1. Prosulfuron Technical for formulation into herbicides for the use on corn (EPA Registration Number 100-762).
2. Peak Herbicide (formerly Exceed WG) for weed control in field corn (grown for grain, silage, or seed), popcorn, and sweet corn (EPA Registration Number 100-763).
   
3. Exceed for weed control in field corn (grown for grain, silage, or seed), and popcorn (EPA Registration Number 100-774). A conditional registration may be granted under section 3(c)(7)(C) of FIFRA for a new active ingredient where certain data are lacking, on condition that such data are received by the end of the conditional registration period and do not meet or exceed the risk criteria set forth in 40 CFR 154.7; that use of the pesticide during the conditional registration period will not cause unreasonable adverse effects; and that use of the pesticide is in the public interest. The Agency has considered the available data on the risks associated with the proposed use of prosulfuron and primisulfuronmethyl, and information on social, economic, and environmental benefits to be derived from such use. Specifically, the Agency has considered the nature and its pattern of use, application methods and rates, and level and extent of potential exposure. Based on these reviews, the Agency was able to make basic health and safety determinations which show that use of prosulfuron and primisulfuron-methyl during the period of conditional registration will not cause any unreasonable adverse effect on the environment, and that use of the pesticide is, in the public interest.
   These products are conditionally registered in accordance with FIFRA section 3(c)(7)(C). If the conditions are not complied with the registrations will be subject to cancellation in accordance with FIFRA section 6(e). Ciba-Geigy must make sure that all required studies are submitted under the terms of these conditional registrations. Consistent with section 3(c)(7)(C), the Agency has determined that these conditional registrations are in the public interest. Use of the pesticides are of significance to the user community, and appropriate labeling, use directions, and other measures have been taken to ensure that use of the pesticides will not result in unreasonable adverse effects to man and the environment.
   More detailed information on these conditional registrations is contained in [[Page 38333]]
