The Environmental Protection Agency is providing this “Reader’s
Guide” to allow the reader to more easily access and navigate the
various documents contained in the Naphthalene Acetic Acid, Its Salts
and Acetamide electronic docket.  The documents are posted in Federal
Docket Management System (FDMS) electronic docket in   HYPERLINK
"http://www.regulations.gov"  www.regulations.gov  under
EPA-HQ-OPP-2006-0507.  Each item contains the title of the document, the
date of the document, its author(s) when applicable, and a brief
description of its purpose.  

The Reader’s Guide provides organizational structure to the various
documents in the Naphthalene Acetic Acid, Its Salts and Acetamide docket
grouping related documents.  The first group contains the Federal
Register Notice, Docket Organizational Documents; the October 2007
amended RED, and a Fact Sheet.  The second group contains Human Health
Risk Assessment Documents and the third group contains the Environmental
Risk Assessment documents.  The fourth group includes other significant
background documents.  

EPA is committed to involving stakeholders and the public in its
development of pesticide reregistration and tolerance reassessment
decisions. The Agency's public participation process provides a dynamic
framework for public involvement and consultation during the conduct of
these programs.  As all pesticides do not present the same degree of
risk or complexity of issues, the public participation process provides
options for conducting a full 6-phase process, modified 4-phase process,
or streamlined low risk process, as appropriate.  Using this tailored
approach, EPA promotes robust public involvement while making timely
pesticide regulatory decisions to meet statutory deadlines and program
goals while ensuring that all pesticides meet current health and safety
standards.

Naphthalene Acetic Acid, its Salts, Ester, and Acetamide (also referred
to as “naphthalene acetates” or “NAA”) are plant growth
regulators and are considered low-risk pesticides.  As a result, EPA is
using the streamlined version of the public participation process for
the NAA reregistration and tolerance reassessment decisions.  Through
these programs, EPA is ensuring that all pesticides meet current health
and safety standards.
