Permethrin; Notice of Availability of Risk Assessments and 
Opening of Docket

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's preliminary 
human health and ecological risk assessments and related documents for 
permethrin, a synthetic pyrethroid insecticide, and opens a public 
comment period on these documents. The public is encouraged to provide 
information to refine assessed risks, and suggest risk management ideas 
or proposals to address the risks identified. At this time, EPA is 
intending to develop a Reregistration Eligibility Decision (RED) for 
permethrin through a modified 4-phase public participation process that 
the Agency uses to involve the public in developing pesticide 
reregistration and tolerance assessment decisions. For permethrin, a 
modified 4-Phase process with one public comment period and ample 
opportunity for public consultation seems appropriate in view of the 
number and level of risk concerns identified in the preliminary risk 
assessment. 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 consider an additional comment 
period, as needed. Through this program, EPA is ensuring that all 
pesticides meet current health and safety standards. This notice is 
phase-3 of the 4-phase process.

DATES: Comments, identified by docket identification (ID) number OPP-
2004-0385 must be received on or before October 31, 2005.

ADDRESSES: Comments may be submitted electronically, by mail, or 
through hand delivery/courier. Follow the detailed instructions as 
provided in Unit I. of the SUPPLEMENTARY INFORMATION.

FOR FURTHER INFORMATION CONTACT: Jacqueline Guerry, Chemical Review 
Manager, Special Review and Reregistration Division (7508C), Office of 
Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania

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?

    We invite you to provide your views on the various options we

II. Background

A. What Action is the Agency Taking?

    EPA is releasing for public comment its preliminary human health 
and environmental fate and effects risk assessments and related 
documents for the synthetic pyrethroid insecticide,

[[Page 51792]]

permethrin, and is encouraging the public to provide information to 
refine identified risks, and suggest risk management ideas or 
proposals. 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). Permethrin is registered for use 
on sites in agricultural, commercial, and residential settings. In 
addition to its pesticidal uses, permethrin also has non-FIFRA 
pharmaceutical use as a pediculicide for the treatment of head lice and 
scabies. The Food and Drug Administration (FDA) approves use of the 
pesticidal-containing pharmaceutical products under FFDCA.
    The preliminary risk assessments have identified potential 
residential postapplication noncancer chronic risks of concerns for 
toddlers; residential handlers and postapplication cancer risks; 
occupational handler and postapplication noncancer chronic and cancer 
risks; and potential acute and chronic ecological risks of concern. EPA 
is providing an opportunity, through this notice, for interested 
parties to provide comments and input on the Agency's risk assessments 
for permethrin. Such comments and input could address the potential 
risks of concern.
    All elements of the Agency's risk assessments for permethrin are 
open for public comment; however, we are particularly seeking public 
comment and input on data that could help refine those scenarios where 
uncertainties exists and risk estimates exceed the level of concern, 
which are identified in the Agency's risk assessments available in the 
docket. Specifically, there is uncertainly regarding the residential 
handler and postapplication cancer risks. In order to identify the 
residential exposure scenarios that may pose risks of concern, the 
Agency is seeking public comment on the typical number of applications 
associated with those homeowner scenarios assessed. Additionally, the 
Agency is looking for consumer information on the market segments that 
utilize impregnated clothing and the use pattern of these products 
(i.e. types of impregnated clothing purchased and worn, number of times 
the article of clothing is worn and washed, etc.). Refer to the 
Permethrin Overview document available in the docket for further 
discussion of uncertainties and data needs regarding residential uses. 
Further, the only occupational risks of concern identified resulted 
from use of permethrin in mushroom houses. The Agency is seeking 
typical use information on permethrin applied in mushroom houses (i.e. 
current level of personal protective equipment worn, application rate, 
and percent crop treated, etc.), as well as benefits of this use, and 
potential risk mitigation ideas. Additionally, the Agency is interested 
in obtaining data or information that would assist in refining the 
risks identified in the ecological assessment, such as the typical use 
of buffer zones in areas where permethrin is applied close to bodies of 
water. Finally, additional data are being requested regarding the 
potential ecological risk resulting from permethrin formulations that 
contain the synergist piperponyl butoxide (PBO). Few toxicity studies 
are available on formulations of permethrin/PBO. In order to assess any 
increased toxicity of permethrin active ingredient when formulated with 
a synergist, the Agency is requesting the submission of existing 
permethrin/PBO toxicity studies, and public comment on additional 
studies that may need to be generated to address this issue. Refer to 
the Overview document for more discussion of this matter.
    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 permethrin, compared to the 
general population.
    EPA is releasing for public comment its risk assessments for 
permethrin, to provide an opportunity for interested parties to also 
provide risk management proposals or otherwise comment on risk 
management. Such comments and proposals should further discuss ways to 
manage permethrin's occupational, residential, and/or ecological risks 
resulting from its many uses, as discussed in the Agency's risk 
assessments.
    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, 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. At this time for 
permethrin, a modified 4-Phase process with one public comment period 
and ample opportunity for public consultation seems appropriate in due 
to the number and level of risk concerns. 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 
consider an additional comment period, as needed.
    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 
permethrin. 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.
