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

     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 
receiving comments. Go directly to EPA Dockets at https://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-2005-0042. 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?

     EPA is making available the Agency's revised risk assessments, 
initially issued

[[Page 55385]]

for comment through a Federal Register notice published on April 27, 
2005 (70 FR 21752) (FRL-7704-6); a response to comments; and related 
documents for piperonyl butoxide. EPA also is soliciting public comment 
on risk reduction options for piperonyl butoxide. EPA developed the 
risk assessments for piperonyl butoxide as part 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).
    Piperonyl butoxide is an insecticide synergist. Synergists are 
chemicals that lack pesticidal effects of their own but enhance the 
pesticidal properties of other chemicals. Piperonyl butoxide is usually 
formulated with natural pyrethrin or synthetic pyrethroids. It has 
numerous and varied commercial and residential applications, is 
available in a broad range of formulations, and is applied by a wide 
variety of application methods.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for piperonyl butoxide. Risks of concern 
associated with the use of piperonyl butoxide are: pest control 
operators (PCOs) and agricultural handlers using wettable powder 
formulated products, post-application inhalation risk from exposure to 
metered release space sprays, and risks to non-target aquatic and 
terrestrial organisms. In targeting these risks of concern, the Agency 
solicits information on effective and practical risk reduction 
measures.
     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, piperonyl butoxide is being 
reviewed through the full 6-Phase public participation process.
     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 and proposals will become part of the Agency 
docket for piperonyl butoxide. Comments received after the close of the 
comment period will be marked ``late.'' EPA is not required to consider 
these late comments.
     After considering comments received, EPA will develop and issue 
the piperonyl butoxide RED.

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 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.
