Sandoz Agro, Inc.; Approval of Pesticide Product Registrations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.
..
------------------------------------------------------------
SUMMARY: This notice announces Agency approval of applications
submitted by Sandoz Agro, Inc., to conditionally register the
pesticide products Frontier Herbicide and San 582H, containing
a new active ingredient 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: Cynthia Giles-Parker,
Product Manager (PM) 22, Registration Division (H7505C), Office
of Pesticide Programs, 401 M St., SW., Washington, DC 20460.
Office location and telephone number: Rm. 229, CM #2, Environmental
Protection Agency, 1921 Jefferson Davis Hwy, Arlington, VA 22202,
(703-305-5540).

SUPPLEMENTARY INFORMATION: EPA issued a notice published in
the Federal Register of December 11, 1991 (56 FR 64624), which
announced that Sandoz Crop Protection Corp., 1300 East Touhy
Avenue, Des Plaines, IL 60018, had submitted applications to
register the pesticide products San 582 7.5L Herbicide and San
582H (EPA File Symbols 55947-RUN and 55947-RUR) containing the
active ingredient 2-chloro-N-[(1-methyl-2-methoxy)ethyl]-N-(2,4-
dimethyl-thien-3-yl)acetamide at 78.5 and 94 percent respectively,
an active ingredient not included in any previously registered
products.

These applications were approved on March 5, 1993, as Frontier
Herbicide (formerly San 582H 7.5L Herbicide), for weed control
in field corn (EPA Registration Number 55947-140) and San 582H
for manufacturing use only (EPA Registration Number 55947-141).
A conditional registration may be granted under section 3(c)(7)(C)
of FIFRA for a new active ingredient where certain data are
lacking because a period reasonably sufficient for generation
of the data has not elapsed since the Administrator first imposed
the data requirements, 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 on the environment;
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 dimethenamid 2-chloro-N-
[(1-methyl-2-methoxy)ethyl]-N-(2,4-dimethyl-thien-3-yl)-acetamide,
and information on social, economic, and environmental benefits
to be derived from such use. Specifically, the Agency has considered
the nature of the chemical 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 dimethenamid
2-chloro-N-[(1-methyl-2-methoxy)ethyl]-N-(2,4-dimethyl-thien-
3-yl)-acetamide during the period of conditional registration
is not expected to cause any unreasonable adverse effect on
the environment, and that use of the pesticide is in the public
interest.
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 on an EPA Pesticide Fact Sheet for dimethenamid
2-chloro-N-[(1-methyl-2-methoxy)ethyl]-N-(2,4-dimethyl-thien-
3-yl)-acetamide.
A copy of the fact sheet, which provides a summary description
of the chemical, use patterns and formulations, science findings,
and the Agency's regulatory position and rationale, may be obtained
from the National Technical Information Service (NTIS), 5285
Port Royal Road, Springfield, VA 22161.
In accordance with section 3(c)(2) of FIFRA, a copy of the
approved label and the list of data references used to support
registration are available for public inspection in the office
of the Product Manager. The data and other scientific information
used to support registration, except for material specifically
protected by section 10 of FIFRA, are available for public inspection
in the Public Response and Program Resources Branch, Field Operations
Division (H7506C), Office of Pesticide Programs, Environmental
Protection Agency, rm. 1128, CM #2, Arlington, VA 22202 (703-
305-5805). Requests for data must be made in accordance with
the provisions of the Freedom of Information Act and must be
addressed to the Freedom of Information Office (A-101), 401
M St., SW., Washington, DC 20460. Such requests should: (1)
