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. 
Using a modified, streamlined version of its public participation 
process, EPA has completed a RED and an Amendment for the low-risk 
naphthalene acetate pesticides under section 4(g)(2)(A) of FIFRA. The 
naphthalene acetates are plant growth regulators that mimic the 
function of the naturally occurring plant growth hormone, auxin. They 
are mainly used on apple and pear trees but also have minor uses on 
crops such as olives and cherries. They are also used on a wide variety 
of ornamental plants, trees, and shrubs. In its various forms, NAA can 
stimulate root growth, thin excess fruit, and prevent premature fruit 
drop. EPA has determined that the database to support reregistration is 
substantially complete and that products containing naphthalene acetic 
acid, its salts, ester, and acetamide will be eligible for 
reregistration provided the risks are mitigated either in the manner 
described in the RED Amendment or by another means that achieves 
equivalent risk reduction. Upon submission of any required product 
specific data under section 4(g)(2)(B) of FIFRA and any necessary 
changes to the registration and labeling (either to address any 
concerns identified in the RED Amendment or as a result of product 
specific data), EPA will make a final reregistration decision under 
section 4(g)(2)(C) of FIFRA for products containing naphthalene 
acetates.
    With the May 26, 2004 RED signature, EPA concluded that the use of 
the naphthalene acetates would have no effect on any endangered or 
threatened species or their critical habitat from the uses currently 
registered based on its screening-level assessment. However, the Agency 
was informed that one very minor use, on olive trees as a chemical 
thinning agent, has an approved application rate higher than assessed 
in the RED. Based on screening-level ecological and occupational 
assessments of the higher use rate, calculated risk quotients (RQs) for 
NAA use on olive trees then exceeded the level of concern for 
endangered species and one worker exposure scenario exceeds the 
occupational level of concern. The Agency performed a refined risk 
assessment with additional data, which allowed EPA to characterize the 
risks and determine that risks were at an acceptable level. The Agency 
is issuing an Amended RED for NAA, which reflects the refined 
occupational and ecological assessments.
    In addition, certain components of the document, which did not 
affect the final regulatory decision, were undergoing final editing at 
the time of the RED's signature. These components, including the list 
of additional generic data requirements, summary of labeling changes, 
appendices, and other relevant information, have been added to the 
naphthalene acetic acid, its salts, ester, and acetamide RED Amendment 
document. Subsequent to signature, EPA identified some minor errors and 
ambiguities in the original RED. Therefore, for the sake of accuracy, 
the Agency also has included the appropriate error corrections and 
clarifications to the RED Amendment. None of these additions or changes 
impacts the decisions described in the NAA RED or its Amendment. These 
changes are described in the preamble to the naphthalene acetic acid, 
its salts, ester, and acetamide RED Amendment.
    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, 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 the 
naphthalene acetates, which pose few risk concerns, and require little 
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 naphthalene acetic acid, 
its salts, ester, and acetamide RED and its Amendment.
    The reregistration program is being conducted under congressionally 
mandated timeframes, and EPA recognizes the need both to make timely 
decisions and to involve the public in finding ways to effectively 
mitigate pesticide risks. NAA, however, poses few risks that require 
mitigation. The Agency therefore is issuing the naphthalene acetic 
acid, its salts, ester, and acetamide RED and Amendment, its risk 
assessments, and related support materials simultaneously for public 
comment. The comment period is intended to provide an opportunity for 
public input and a mechanism for initiating any additional amendments 
to the RED. All comments should be submitted using the methods in 
ADDRESSES, and must be received by EPA on or before the closing date. 
These comments will become part of the Agency Docket for naphthalene 
acetic acid, its salts, ester, and acetamide. 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 regulations.gov. 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 
naphthalene acetic acid, its salts, ester, and acetamide RED as amended 
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.''
