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

II. Background

A. What Action is the Agency Taking?

    EPA has reassessed the uses of imazaquin and the one existing 
tolerances or legal residue limits. On December 20, 2005, EPA reached a 
tolerance reassessment decision for this low risk pesticide. Imazaquin 
is an imidazolinone herbicide which controls weeds by inhibiting the 
synthesis of specific amino acids (valine, leucine and isoleucine) 
necessary for plant growth. It is registered as a pre-plant, 
preemergence and early postemergence herbicide for use on soybeans, 
primarily across the central Midwest from Kentucky to Illinois and 
across the mid-South in Arkansas, Louisiana and Mississippi. It is also 
registered for pre- and postemergence weed control on ornamentals and 
warm season turfgrass in both residential and non-residential settings. 
The turf and ornamental uses are concentrated across the southern U.S. 
because of imazaquin's lack of selectivity on cool season grasses. The 
Agency is now issuing for comment the resulting Report on Food Quality 
Protection Act (FQPA) Tolerance Reassessment Progress and Risk 
Management Decision for imazaquin, known as a TRED, as well as related 
risk assessments and technical support documents.
    EPA developed the imazaquin TRED through a modified, streamlined 
version of its public process for making tolerance reassessment and 
reregistration eligibility decisions. Through these programs, the 
Agency is ensuring that pesticides meet current standards under the 
Federal Food, Drug, and Cosmetic Act (FFDCA) and the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended by 
FQPA. EPA must review tolerances and tolerance exemptions that were in 
effect when the FQPA was enacted, 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 
imazaquin 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 of May 14, 
2004 (69 FR 26819) (FRL-7357-9) explains that in conducting these 
programs, the Agency 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. 
EPA can expeditiously reach decisions for pesticides like imazaquin, 
which pose no risk concerns, and require no risk mitigation. Once EPA 
assesses uses and risks for such low risk pesticides, the Agency may go 
directly to a decision and prepare a document summarizing its findings, 
such as the imazaquin TRED.
    The tolerance reassessment program is being conducted under 
Congressionally mandated time frames, and EPA recognizes the need both 
to make timely decisions and to involve the public in finding ways to 
effectively mitigate pesticide risks. Imazaquin, however, poses no 
risks that require mitigation. The Agency therefore is issuing the 
imazaquin TRED, its risk assessments, and related support documents 
simultaneously for public comment. The comment period is intended to 
provide an opportunity for public input and a mechanism for initiating 
any necessary amendments to the TRED. 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 imazaquin. Comments received after 
the close of the comment period will be marked ``late.'' EPA is not 
required to consider these late comments.
    EPA 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 TRED in the Federal 
Register. In the absence of substantive comments requiring changes, the 
decisions reflected in the TRED will be implemented as presented. These 
decisions may be supplemented by risk mitigation measures when EPA 
considers its cumulative assessment of the cumulative group pesticides.

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

    Section 408(q) of the 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.
