SUMMARY: This notice announces the availability of EPA's Reregistration 
Eligibility Decision (RED) for the pesticide thidiazuron, and opens a 
public comment period on this document. The Agency's risk assessments 
and other related

[[Page 69558]]

documents also are available in the thidiazuron docket. Thidiazuron is 
registered for use as a pre-harvest cotton defoliant or growth 
regulator. It removes green leaves and immature fruiting structures, 
which contribute to cotton staining. EPA has reviewed thidiazuron 
through the public participation process that the Agency uses to 
involve the public in developing pesticide reregistration and tolerance 
reassessment decisions. Through these programs, EPA is ensuring that 
all pesticides meet current health and safety standards.

will be placed in EPA's electronic public docket along with a brief 
description written by the docket staff.

C. How and to Whom Do I Submit Comments?

    You may submit comments electronically, by mail, or through hand 
delivery/courier. To ensure proper receipt by EPA, identify the 
appropriate docket ID number in the subject line on the first page of 
your comment. Please ensure that your comments are submitted within the 
specified comment period. Comments received after the close of the 
comment period will be marked ``late.'' EPA is not required to consider 
these late comments. If you wish to submit CBI or information that is 
otherwise protected by statute, please follow the instructions in Unit 
I.D. Do not use EPA Dockets or e-mail to submit CBI or information 
protected by statute.
    1.  Electronically. If you submit an electronic comment as 
prescribed in this unit, EPA recommends that you include your name, 
mailing address, and an e-mail address or other contact information in 
the body of your comment. Also include this contact information on the 
outside of any disk or CD ROM you submit, and in any cover letter 
accompanying the disk or CD ROM. This ensures that you can be 
identified as the submitter of the comment and allows EPA to contact 
you in case EPA cannot read your comment due to technical difficulties 
or needs further information on the substance of your comment. EPA's 
policy is that EPA will not edit your comment, and any identifying or 
contact information provided in the body of a comment will be included 
as part of the comment that is placed in the official public docket, 
and made available in EPA's electronic public docket. If EPA cannot 
read your comment due to technical difficulties

[[Page 69559]]

and cannot contact you for clarification, EPA may not be able to 
consider your comment.
    i.EPA Dockets. Your use of EPA's electronic public docket to submit 
comments to EPA electronically is EPA's preferred method for receiving 
comments. Go directly to EPA Dockets at http://www.epa.gov/edocket/, 
and follow the online instructions for submitting comments. Once in the 
system, select ``search,'' and then key in docket ID number OPP-2004-
0382. The system is an ``anonymous access'' system, which means EPA 
will not know your identity, e-mail address, or other contact 
information unless you provide it in the body of your comment.

docket's normal hours of operation as identified in Unit I.B.1.

D. How Should I Submit CBI to the Agency?

    Do not submit information that you consider to be CBI 
electronically through EPA's electronic public docket or by e-mail. You 
may claim information that you submit to EPA as CBI by marking any part 
or all of that information as CBI (if you submit CBI on disk or CD ROM, 
mark the outside of the disk or CD ROM as CBI and then identify 
electronically within the disk or CD ROM the specific information that 
is CBI). Information so marked will not be disclosed except in 
accordance with procedures set forth in 40 CFR part 2.
    In addition to one complete version of the comment that includes 
any information claimed as CBI, a copy of the comment that does not 
contain the information claimed as CBI must be submitted for inclusion 
in the public docket and EPA's electronic public docket. If you submit 
the copy that does not contain CBI on disk or CD ROM, mark the outside 
of the disk or CD ROM clearly that it does not contain CBI. Information 
not marked as CBI will be included in the public docket and EPA's 
electronic public docket without prior notice. If you have any 
questions about CBI or the procedures for claiming CBI, please consult 
the person listed under FOR FURTHER INFORMATION CONTACT.

E. What Should I Consider as I Prepare My Comments for EPA?

    You may find the following suggestions helpful for preparing your 
comments:
    1. Explain your views as clearly as possible.
    2. Describe any assumptions that you used.
    3. Provide any technical information and/or data you used that 
support your views.
    4. If you estimate potential burden or costs, explain how you 
arrived at your estimate.
    5. Provide specific examples to illustrate your concerns.
    6. Offer alternatives.
    7. Make sure to submit your comments by the comment period deadline 
identified.
    8. To ensure proper receipt by EPA, identify the appropriate docket 
ID number in the subject line on the first page of your response. It 
would also be helpful if you provided the name, date, and Federal 
Register citation related to your comments.

II. Background

A. What Action is the Agency Taking?

    Under section 4 of the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA), EPA is reevaluating existing pesticides to 
ensure that they meet current scientific and regulatory standards. EPA 
has completed a Reregistration Eligibility Decision (RED) for the 
pesticide, thidiazuron under section 4(g)(2)(A) of FIFRA. Thidiazuron 
is registered for use as a pre-harvest cotton defoliant or growth 
regulator. It removes green leaves and immature fruiting structures, 
which contribute to cotton staining. EPA has determined that the data 
base to support reregistration is substantially complete and that 
products containing thidiazuron are eligible for reregistration, 
provided the potential risks are mitigated either in the manner 
described in the RED or by another means that achieves equivalent risk 
reduction. Upon submission of any required product specific data under 
section 4(g)(2)(B) and any necessary changes to the registration and 
labeling (either to address concerns identified in the RED or as a 
result of product specific data), EPA will make a final reregistration 
decision under section 4(g)(2)(C) for products containing thidiazuron.
    EPA must review tolerances and tolerance exemptions that were in 
effect when the Food Quality Protection Act (FQPA) was enacted in 
August 1996, to ensure that these existing pesticide residue limits for 
food and feed commodities meet the safety standard established by the 
new law. Tolerances are considered reassessed once the safety finding 
has been made or a revocation occurs. EPA has reviewed and made the 
requisite safety finding for the thidiazuron tolerances included in 
this notice.
    EPA is applying the principles of public participation to all 
pesticides undergoing reregistration and tolerance reassessment. The 
Agency's Pesticide Tolerance Reassessment and Reregistration; Public 
Participation Process, published in the Federal Register on May 14, 
2004, (69 FR 26819)(FRL-7357-9) explains that in conducting these 
programs, EPA is tailoring its public participation process to be 
commensurate with the level of risk, extent of use, complexity of 
issues, and degree of public concern associated with each pesticide. 
Due to its uses, risks, and other factors, thidiazuron was reviewed 
through the modified 4-Phase process. Through this process, EPA worked 
extensively with stakeholders and the public to reach the regulatory 
decisions for thidiazuron.
    The reregistration program is being conducted under Congressionally 
mandated time frames, and EPA recognizes the need both to make timely 
decisions and to involve the public. The Agency is issuing the 
thidiazuron RED for public comment. This comment period is intended to 
provide an additional opportunity for public input

[[Page 69560]]

and a mechanism for initiating any necessary amendments to the RED. All 
comments should be submitted using the methods in Unit I. of the 
SUPPLEMENTARY INFORMATION, and must be received by EPA on or before the 
closing date. These comments will become part of the Agency Docket for 
thidiazuron. Comments received after the close of the comment period 
will be marked ``late.'' EPA is not required to consider these late 
comments.
    The Agency will carefully consider all comments received by the 
closing date and will provide a Response to Comments Memorandum in the 
Docket and electronic EDOCKET. If any comment significantly affects the 
document, EPA also will publish an amendment to the RED in the Federal 
Register. In the absence of substantive comments requiring changes, the 
thidiazuron RED will be implemented as it is now presented.

B. What is the Agency's Authority for Taking this Action?

    Section 4(g)(2) of FIFRA as amended directs that, after submission 
of all data concerning a pesticide active ingredient, ``the 
Administrator shall determine whether pesticides containing such active 
ingredient are eligible for reregistration,'' before calling in product 
specific data on individual end-use products and either reregistering 
products or taking other ``appropriate regulatory action.''
    Section 408(q) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 
21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for 
pesticide residues in effect as of August 2, 1996, to determine whether 
the tolerance or exemption meets the requirements of section 408(b)(2) 
or (c)(2) of FFDCA. This review is to be completed by August 3, 2006.
