ENVIRONMENTAL PROTECTION AGENCY

Receipt of Application for Emergency Exemptions to use Propazine; 
Solicitation of Public Comment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: EPA has received a specific exemption request from the 
Oklahoma Department of Agriculture (hereafter referred to as the 
``Applicant'') to use the pesticide propazine (CAS 139-40-2) to treat 
up to 280,000 acres of sorghum to control various weeds. The Applicant 
proposes the use of a new (unregistered) chemical; therefore, in 
accordance with 40 CFR 166.24, EPA is soliciting public comment before 
making the decision whether or not to grant the exemption.

DATES: Comments must be received on or before February 24, 1994.

ADDRESSES: Three copies of written comments, bearing the identification 
notation ``OPP-180919,'' should be submitted by mail to: Public 
Response and Program Resource Branch, Field Operations Division 
(7506C), Office of Pesticide Programs, Environmental Protection Agency, 
401 M St., SW., Washington, DC 20460. In person, bring comments to: Rm. 
1132, Crystal Mall #2, 1921 Jefferson Davis Highway, Arlington, VA.
    Information submitted in any comment concerning this notice may be 
claimed confidential by marking any part or all of that information as 
``Confidential Business Information.'' Information so marked will not 
be disclosed except in accordance with procedures set forth in 40 CFR 
part 2. A copy of the comment that does not contain Confidential 
Business Information must be provided by the submitter for inclusion in 
the public record. Information not marked confidential may be disclosed 
publicly by EPA without prior notice. All written comments filed 
pursuant to this notice will be available for public inspection in Rm. 
1132, Crystal Mall No. 2, 1921 Jefferson Davis Highway, Arlington, VA, 
from 8 a.m. to 4 p.m., Monday through Friday, except legal holidays.

FOR FURTHER INFORMATION CONTACT: By mail: Andrea Beard, Registration 
Division (7505W), Office of Pesticide Programs, Environmental 
Protection Agency, 401 M St., SW, Washington, DC 20460. Office location 
and telephone number: Floor 6, Crystal Station #1, 2800 Jefferson Davis 
Highway, Arlington, VA, (703-308-8791).

SUPPLEMENTARY INFORMATION: Pursuant to section 18 of the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 136p), 
the Administrator may, at her discretion, exempt a state agency from 
any registration provision of FIFRA if she determines that emergency 
conditions exist which require such exemption. The Applicant has 
requested the Administrator to issue a specific exemption for the use 
of propazine on sorghum to control pigweed. Information in accordance 
with 40 CFR part 166 was submitted as part of this request.
    Sorghum is grown as a rotational crop with cotton and wheat, in 
order to comply with the soil conservation requirements. Propazine, 
which was formerly registered for use on sorghum, was voluntarily 
canceled by the former Registrant, who did not wish to support its re-
registration. The Applicant claims that this has left many sorghum 
growers with no pre-emergent herbicides that will adequately control 
certain broadleaf weeds, especially pigweed. Until recently, growers 
have been using up existing stocks of propazine. The Applicant states 
that other available herbicides have serious limitations on their use, 
making them unsuitable for control of pigweed in sorghum. Although the 
original Registrant of propazine has decided not to support this 
chemical through re-registration, another company has committed to 
support the data requirements for this use. Propazine was once 
registered for this use, but has now been voluntarily canceled and is 
therefore considered to be a new chemical.
    The Applicant states that, because growers have been using existing 
stocks of propazine since the time of its voluntary cancellation, 
yields have not shown a decrease. However, this is the first season 
where most growers have depleted their stocks of propazine, and the 
Applicant claims that significant economic losses will occur without 
the availability of propazine.
    The Applicant proposes to apply propazine at a maximum rate of 1.2 
lbs. active ingredient (a.i.), (2.4 pts. of product) per acre, by 
ground or air, with a maximum of one application per crop growing 
season. Therefore, use under this exemption could potentially amount to 
a maximum total of 336,000 lbs. of active ingredient (84,000 gal. of 
product). This is the first time that Oklahoma has applied for this use 
of propazine on sorghum.
    Requests for exemptions were also received earlier this year from 
New Mexico and Texas, and Texas was issued an exemption for this use 
for last growing season. This notice does not constitute a decision by 
EPA on the application itself. The regulations governing section 18 
require publication of a notice of receipt of an application for a 
specific exemption proposing use of a new chemical (i.e., an active 
ingredient not contained in any currently registered pesticide). Such 
notice provides for opportunity for public comment on the application. 
Accordingly, interested persons may submit written views on this 
subject to the Field Operations Division at the address above.
    The Agency, accordingly, will review and consider all comments 
received during the comment period in determining whether to issue the 
emergency exemption requested by the Oklahoma Department of 
Agriculture.
