ENVIRONMENTAL PROTECTION AGENCY
[OPP-180929; FRL 4771-2]
Receipt of Application for Emergency Exemption To Use
Imidacloprid; Solicitation of Public Comment
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: EPA has received specific exemption requests from the Oregon
and Utah Departments of Agriculture (hereafter referred to as the
``Applicants'') to use the pesticide Imidacloprid (CAS 105827-78-9) to
treat up to 13,000 acres of apples to control aphids. The Applicants
propose the use of a new 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 April 21, 1994.
ADDRESSES: Three copies of written comments, bearing the identification
notation ``OPP-180929,'' 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, D.C. 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, D.C. 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 Applicants have
requested the Administrator to issue specific exemptions for the use of
imidacloprid on apples to control aphids. Information in accordance
with 40 CFR part 166 was submitted as part of this request.
The Applicants state that aphids have been a chronic pest of apples
in Oregon and Utah. Aphids feed on the plant tissues of young trees,
which can stunt growth and affect future tree productivity. On large,
vigorous trees, the primary concern is fruit damage. Aphids excrete
such large amounts of honeydew that it drips on the fruit, causing
russetting or providing a substrate for the growth of sooty mold. The
value of such damaged fruit is considerably reduced, as it is diverted
to a processing market. The Applicants state that some of the
registered alternative pesticides, while once effective, have lost much
of their effectiveness due to build-up of resistant aphid populations.
Others are said to only provide suppression, and not adequately control
aphids. One of the registered alternatives (phosphamidon) that is still
somewhat effective for this pest problem was withdrawn from the market
in 1991, due to non-support for re-registration, and existing stocks
have been mostly depleted. Another chemical (mevinphos) was previously
used for this pest, but because of human risk concerns the manufacturer
removed all labeled uses of mevinphos on apples and pears from the
label in 1993. Therefore, the Applicants claim that Oregon and Utah
apple growers are left without adequate means to control aphids. The
Applicants anticipate crop value losses of approximately 10 percent
without the availability of imidacloprid this growing season.
The Oregon and Utah Departments of Agriculture propose that
imidacloprid be used at a maximum rate of 0.1 lb. active ingredient
(a.i.), or 6.4 fluid oz. of product, per acre with a maximum of 5
applications. No more than 0.5 lb. a.i. (32 fluid oz. of product)
applied per year. Oregon proposes treatment on up to 9,500 acres of
apples. This would total approximately 4,750 lbs. of a.i, or 2,375 gal.
of product. Utah proposes treatment on up to 3,363 acres of apples.
This would total approximately 1,682 lbs. of a.i., or 841 gal. of
product. This is the first time the Applicants have applied for the use
of imidacloprid on apples. A section 18 for this use of imidacloprid
was issued by the Agency to Washington State on March 7, 1994 for up to
160,980 acres.
This notice does not constitute a decision by EPA on the
applications themselves. 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 Oregon and Utah Departments of
Agriculture.
