ENVIRONMENTAL PROTECTION AGENCY
[OPP-181055; FRL 5779-4]
Pyriproxyfen and Buprofezin; Receipt of Application for Emergency
Exemptions, Solicitation of Public Comment
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: EPA has received specific exemption requests from the
California Department of Pesticide Regulation (hereafter referred to as
the ``Applicant'') to use the insect growth regulators pyriproxyfen
(CAS 95737-68-1) and buprofezin (CAS 69327-76-0) to treat up to 45,000
acres of citrus to control California Red Scale. In the case of
pyriproxyfen, the Applicant proposes the first food use of an active
ingredient. Buprofezin is an unregistered material, and its proposed
use is thus 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 exemptions.
DATES: Comments must be received on or before April 9, 1998.
ADDRESSES: Three copies of written comments, bearing the identification
notation ``OPP-181055,'' should be submitted by mail to: Public
Information and Records Integrity Branch, Information Resources and
Services Division (7502C), Office of Pesticide Programs, Environmental
Protection Agency, 401 M St., SW., Washington, DC 20460. In person,
bring comments to: Rm. 119, Crystal Mall #2, 1921 Jefferson Davis
Highway, Arlington, VA.
Comments and data may also be submitted electronically to: opp-
[email protected]. Follow the instruction under ``SUPPLEMENTARY
INFORMATION.'' No Confidential Business Information (CBI) should be
submitted through e-mail.
Information submitted in any comment concerning this notice may be
claimed confidential by marking any part or all of that information as
CBI. 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 CBI must be submitted for inclusion in the public
record. Information not marked confidential may be included in the
public record by EPA without prior notice. The public docket is
available for public inspection in Rm. 119, Crystal Mall #2, 1921
Jefferson Davis Highway, Arlington, VA, from 8:30 a.m. to 4 p.m.,
Monday through Friday, excluding legal holidays.

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 specific exemptions for the use of
pyriproxyfen and buprofezin on citrus to control California Red Scale.
Information in
[[Page 14461]]
accordance with 40 CFR part 166 was submitted as part of this request.
The Applicant states that California Red Scale is a key pest of
citrus, and the single most costly pest to control. The Applicant
states that in the past, treatments were not required every year for
this pest, but in recent years resistance to the registered materials
has built up and growers have had to treat up to three times in a
single year. Alternative methods of control (parasite releases and
packing house washers) are applied where feasible; however, the
Applicant asserts that a a different chemistry with a different mode of
action is necessary to control the scale. The Applicant asserts that
with continued frequent use of currrently registered materials,
increased resistance is likely, and these materials will quickly become
wholy ineffective, leaving growers with no tools to control these
damaging pests. The Applicant states that without adequate control of
scale in citrus, significant economic losses are expected. The
Applicant indicates that one application of either one or the other of
the requested chemicals would not provide adequate control throughout
the season, and since application of either would be limited to one, is
requesting the use of both materials.
The Applicant proposes to apply pyriproxyfen at a rate of 0.108 lb.
active ingredient (a.i.) per acre with a maximum of one application per
crop season on up to 45,000 acres of citrus. The Applicant proposes to
apply buprofezin at a maximum rate of 2.0 lbs. a.i. per acre with a
maximum of one application per crop season on up to 45,000 acres of
cotton. Therefore, use under these exemptions could potentially amount
to a maximum total of 4,860 lbs. of pyriproxyfen and 90,000 lbs. of
buprofezin.
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 in the Federal Register for an
application for a specific exemption proposing the first food use of an
active ingredient, or for use of a new (unregistered) chemical. Such
notice provides for opportunity for public comment on the application.
The official record for this notice, as well as the public version,
has been established for this notice under docket number [OPP-181055]
(including comments and data submitted electronically as described
below). A public version of this record, including printed, paper
versions of electronic comments, which does not include any information
claimed as CBI is available for inspection from 8:30 a.m. to 4 p.m.,
Monday through Friday, excluding legal holidays. The official notice
record is located at the address in ``ADDRESSES''at the beginning of
this document.
Electronic comments can be sent directly to EPA at: opp-

Electronic comments must be submitted as an ASCII file avoiding the
use of special characters and any form of encryption. Comments and data
will also be accepted on disks in WordPerfect in 5.1/6.1 or ASCII file
format. All comments and data in electronic form must be identified by
the docket number [OPP-181055]. Electronic comments on this notice may
be filed online at many Federal Depository Libraries.
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 California Department of Pesticide
Regulation.
