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

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,

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 tributyltin oxide, tributyltin benzoate, and tributyltin maleate,
and soliciting public comment on risk management ideas or proposals.
These three pesticide active ingredients are registered for a wide
variety of uses, including antifoulants in specific, limited
applications, and to control microbial growth in water cooling towers,
construction materials, coatings, textiles, and animal housing
facilities and hatchery applications. EPA developed the risk
assessments and risk characterization for tributyltin oxide,
tributyltin benzoate, and tributyltin maleate 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 three tributyltin (TBT) compounds are formulated for
application both in manufacturing processes and as end-use products
applied directly by consumers. TBT oxide is registered for use in sites
including antifoulant-impregnated rubber shaped for sonar domes,
antifoulant components of oceanographic instruments, wood
preservatives, construction materials including drywall, sterilants for
nonfood processing equipment used in materials manufacture, hard
surface disinfectants for hatchery and poultry/swine farm premises, and
textiles. TBT benzoate is registered for use in sites including
construction materials such as spackling compound and in adhesives for
non-food contact surfaces. TBT maleate is registered for use as a
materials preservative in sites including foam, textiles, carpet
backing, and adhesives.
    EPA is providing an opportunity, through this notice, for
interested parties to provide comments and input on the Agency's risk
assessments for tributyltin oxide, tributyltin benzoate, and
tributyltin maleate. Such comments and input could address, for
example, the availability of additional data to further refine the risk
assessments, including information on residues of TBT in livestock and
eggs from treated facilities, dermal and inhalation unit exposure
values, leaching from treated wood, immunotoxicity, bioaccumulation,
the availability of cost-effective alternatives to TBT, and unique
benefits for the use of TBT could address the Agency's risk assessment
methodologies and assumptions as applied to this specific pesticide.
    Through this notice, EPA also is providing an opportunity for
interested parties to provide risk management proposals or otherwise
comment on risk management for tributyltin oxide, tributyltin benzoate,
and tributyltin maleate. Risks of concern associated with the use of
these active ingredients are: Those associated with immunotoxicity,
endocrine disruption, and bioaccumulation; application of wood
preservative formulations; wearing treated clothing; using a treated
mattress cover; worker application and post-application tasks for TBT
treatments of agricultural premises; re-entry into treated agricultural
premises; liquid pouring for manufacture of construction materials, and
oilfield uses. In targeting these risks of concern, the Agency solicits
information on effective and practical risk reduction measures.
    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 tributyltin oxide,
tributyltin benzoate, and tributyltin maleate, compared to the general
    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 tributyltin oxide, tributyltin benzoate, and tributyltin
maleate, a modified, 4-Phase process with one comment period for public
consultation seems appropriate in view of its limited use. 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
    All comments should be submitted using the methods in ADDRESSES,
and must be received by EPA on or before the closing date. Comments
will become part of the Agency Docket for tributyltin oxide,
tributyltin benzoate, and tributyltin maleate. 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.''
