Information claimed as CBI and other information whose disclosure is 
restricted by statute, which is not included in the official public 
docket, will not be available for public viewing in EPA's electronic 
public docket. EPA's policy is that copyrighted material will not be 
placed in EPA's electronic public docket but will be available only in 
printed, paper form in the official public docket. To the extent 
feasible, publicly available docket materials will be made available in 
EPA's electronic public docket. When a document is selected from the 
index list in EPA Dockets, the system will identify whether the 
document is available for viewing in EPA's electronic public docket. 
Although not all docket materials may be available electronically, you 
may still access any of the publicly available docket materials through 
the docket facility identified in Unit I.B.1. EPA intends to work 
towards providing electronic access to all of the publicly available 
docket materials through EPA's electronic public docket.
    For public commenters, it is important to note that EPA's policy is 
that public comments, whether submitted electronically or in paper, 
will be made available for public viewing in EPA's electronic public 
docket as EPA receives them and without change, unless the comment 
contains copyrighted material, CBI, or other information whose

be scanned and placed in EPA's electronic public docket. Where 
practical, physical objects will be photographed, and the photograph 
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

[[Page 76819]]

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 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

the 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:

    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?

    EPA is releasing for public comment its human health and 
environmental fate and effects risk assessments and related documents 
for cypermethrin, a pyrethroid pesticide, and soliciting public comment 
on risk management ideas or proposals. EPA developed the risk 
assessments and risk characterization for cypermethrin through a 
modified version of its public process for making pesticide 
reregistration eligibility and tolerance reassessment decisions. 
Through these programs, EPA is ensuring that pesticides meet current 
standards under the Federal Insecticide, Fungicide, and Rodenticide Act 
(FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as 
amended by the Food Quality Protection Act of 1996 (FQPA).
    The majority of cypermethrin use is non-agricultural. Cypermethrin 
is registered for indoor and outdoor use on industrial, commercial, and 
residential sites, including use by homeowners. When applied indoors, 
cypermethrin is used to control insect pests such as ants, cockroaches, 
termites, spiders. Other non-food-contact uses include outdoor 
application to structures and lawns (e.g., as a soil residual 
termiticide), application to commercial storage facilities (indoor and 
outdoor), eating establishments (indoor and outdoor, non food contact 
only), dairy facilities (indoor and outdoor, non food contact only), 
food stores or processing plants (indoor and outdoor, non food contact 
only), poultry processing facilities (indoor and outdoor, non food 
contact only), motor vehicles, and swimming pool water systems. In 
agriculture, cypermethrin is applied as a foliar spray to control 
insect pests primarily in cotton, with lesser use on pecans, cole 
crops, lettuce, onions, and other minor

[[Page 76820]]

crops. Cypermethrin can be applied directly to cattle (ear tags) and 
horses, and to pet (dog, horse) sleeping quarters.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessments for cypermethrin. Such comments and input could address, 
for example, the availability of additional data to further refine the 
risk assessments, such as information on indoor and outdoor residential 
and other non-agricultural uses, including typical application rates 
and total pounds of active ingredient applied, methods of application, 
and frequency of re-application.
    From the human health effects assessment, there is the potential 
for short-term risk to toddlers exposed to cypermethrin following 
indoor crack and crevice treatments. From the environmental fate 
assessment, there is the potential for acute and chronic risk to 
aquatic invertebrates and fish from agricultural applications, with the 
highest potential acute risk to estuarine/marine invertebrates. 
Although exposure to aquatic organisms from outdoor, non-agricultural 
uses of cypermethrin could not be assessed at this time, data recently 
submitted to EPA from a study of an urban creek in California suggest 
the potential for aquatic exposure and risk from urban runoff, as well. 
In targeting these risks of concern, the Agency solicits information on 
effective and practical risk reduction measures, such as specific 
application procedures and other measures to reduce runoff from outdoor 
applications to structures and lawns.
    EPA seeks to achieve environmental justice, the fair treatment and 
meaningful involvement of all people, regardless of race, color, 
national origin, or income, in the development, implementation, and 
enforcement of environmental laws, regulations, and policies. To help 
address potential environmental justice issues, the Agency seeks 
information on any groups or segments of the population who, as a 
result of their location, cultural practices, or other factors, may 
have atypical, unusually high exposure to cypermethrin, compared to the 
general population.
    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 
the issues, and degree of public concern associated with each 
pesticide. For cypermethrin, a modified, 4-Phase process with one 
comment period and ample opportunity for public consultation seems 
appropriate. However, if as a result of comments received during this 
comment period EPA finds that additional issues warranting further 
discussion are raised, the Agency may lengthen the process and include 
a second comment period, as needed.
    Cypermethrin is a member of the pyrethroid class of pesticides. 
Although all pyrethroids alter nerve function by modifying the normal 
biochemistry and physiology of nerve membrane sodium channels, EPA is 
not currently following a cumulative risk approach based on a common 
mechanism of toxicity for the pyrethroids. Although all pyrethroids 
interact with sodium channels, there are multiple types of sodium 
channels and it is currently unknown whether the pyrethroids have 
similar effects on all channels. The Agency does not have a clear 
understanding of effects on key downstream neuronal function e.g., 
nerve excitability, nor do we understand how these key events interact 
to produce their compound specific patterns of neurotoxicity. There is 
ongoing research by EPA's Office of Research and Development and 
pyrethroid registrants to evaluate the differential biochemical and 
physiological actions of pyrethroids in mammals. This research is 
expected to be completed by 2007. When available, the Agency will 
consider this research and make a determination of common mechanism as 
a basis for assessing cumulative risk. Information regarding EPA's 
procedures for assessing cumulative effects of substances found to have 
a common mechanism of toxicity is available on EPA's website at http://www.epa.gov/pesticides/cumulative/.
 The decisions presented in the 

Reregistration Eligibility Decision (RED) may be supplemented by 
further risk mitigation measures when EPA considers the cumulative 
risks of the pyrethroid pesticides.
    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. Comments will become part of the Agency Docket for 
cypermethrin. Comments received after the close of the comment period 
will be marked ``late.'' EPA is not required to consider these late 
comments.

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 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.
