ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OPP-2005-0042; FRL-8066-1]


Piperonyl Butoxide (PBO) Reregistration Eligibility Decision; 
Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's Reregistration 
Eligibility Decision (RED) for the pesticide piperonyl butoxide, and 
opens a public comment period on this document. The Agency's risk 
assessments and other related documents also are available in the 
piperonyl butoxide Docket. Piperonyl butoxide (PBO) is a pesticide 
active ingredient that acts as a synergist. Synergists are chemicals 
which, while lacking pesticidal properties of their own, enhance the 
pesticidal properties of other active ingredients including pyrethrins 
and pyrethroids. PBO is used in four general ways: Preharvest and 
postharvest uses on many agricultural crops; direct and indirect 
treatments of livestock animals and premises; treatments of commercial 
and industrial facilities and storage areas where raw and processed 
food/feed commodities are stored or processed; and mosquito abatement 
areas. EPA has reviewed piperonyl butoxide through the public 
participation process that the Agency uses to involve the public in 
developing pesticide reregistration and tolerance reassessment 
decisions. Through these programs, EPA is ensuring that all pesticides 
meet current health and safety standards.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

    This action is directed to the public in general, and may be of 
interest to a wide range of stakeholders including environmental, human 
health, and agricultural advocates; the chemical industry; pesticide 
users; and members of the public interested in the sale, distribution, 
or use of pesticides. Since others also may be interested, the Agency 
has not attempted to describe all the specific entities that may be 
affected by this action. If you have any questions regarding the 
applicability of this action to a particular entity, consult the person 
listed under FOR FURTHER INFORMATION CONTACT.

B. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
regulations.gov or e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD ROM that you mail to EPA, 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 claimed as CBI. In addition to one 
complete version of the comment that includes 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. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When submitting comments, 
remember to:
    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
     ii. Follow directions. The Agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.

    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
    vi. Provide specific examples to illustrate your concerns and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period

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. EPA 
has completed a Reregistration Eligibility Decision (RED) for the 
pesticide, piperonyl butoxide under section 4(g)(2)(A) of FIFRA. 
Piperonyl butoxide (PBO) is a pesticide active ingredient that acts as 
a synergist. Synergists are chemicals which, while lacking pesticidal 
properties of their own, enhance the pesticidal properties of other 
active ingredients including pyrethrins and pyrethroids. PBO is used in 
four general ways: Preharvest and postharvest uses on many agricultural 
crops; direct and indirect treatments of livestock animals and 
premises; treatments of commercial and industrial facilities and 
storage areas where raw and processed food/feed commodities are stored 
or processed; and mosquito abatement areas. EPA has determined that the 
data base to support reregistration is substantially complete and that 
products containing piperonyl butoxide are eligible for reregistration, 
provided the risks are mitigated in the manner described in the RED. 
Upon submission of any required product specific data under section 
4(g)(2)(B) and any necessary changes to the registration and labeling 
(either to address concerns identified in the RED or as a result of 
product specific data), EPA will make a final reregistration decision 
under section 4(g)(2)(C) for products containing piperonyl butoxide.
    EPA must review tolerances and tolerance exemptions that were in 
effect when the Food Quality Protection Act (FQPA) was enacted in 
August 1996, 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 piperonyl butoxide tolerances.
    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 was 
reviewed through the full 6-Phase process. Through this process, EPA 
worked extensively with stakeholders and the public to reach the 
regulatory decisions for piperonyl butoxide.
    The reregistration program is being conducted under Congressionally 
mandated time frames, and EPA recognizes the need both to make timely 
decisions and to involve the public. The Agency is issuing the 
piperonyl butoxide RED for public comment. This comment period is 
intended to provide an additional opportunity for public input and a 
mechanism for initiating any necessary 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 piperonyl butoxide. Comments 
received after the close of the comment period will be marked ``late.'' 
EPA is not required to consider these late comments.
    The Agency 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 
piperonyl butoxide RED will be implemented as it is now presented 
without further notice.

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 Federal Food, Drug, and Cosmetic Act (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.
