HHT Risk Assessments; Notice of Availability and Risk Reduction Options

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's risk
assessments, and related documents for the pesticide hexahydro-1,3,5-
tris(2-hydroxyethyl)-s-triazine HHT, and opens a public comment period
on these documents (Phase 3 of 4-Phase Process). The public is
encouraged to suggest risk management ideas or proposals to address the
risks identified. EPA is developing a Reregistration Eligibility
Decision (RED) for HHT through a modified, 4-Phase public participation
process that the Agency uses to involve the public in developing
pesticide reregistration decisions. Through this program, 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
deadline identified.

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 HHT, and soliciting public comment on risk management ideas or
proposals. HHT is an antimicrobial chemical that displays some
fungicidal activity. The actual antimicrobial agent is formaldehyde
(HCHO) which is released from HHT under proper conditions. EPA
developed the risk assessments and risk characterization for HHT
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).
    Products containing HHT are registered to preserve metalworking
cutting fluids during use and for in-can preservation of adhesives;
chain lubricants; aqueous mineral slurries; paints; stains; coatings;
surfactant/detergent solutions and emulsions; chemical and clinical
reagents; inks and dyes; fuel and oil in storage; indoor construction
compounds such as caulks, spackling, grout, adhesives, foams, etc.; and
drilling muds, workover fluids, and completion fluids.
    EPA is providing an opportunity, through this notice, for
interested parties to provide comments and input on the Agency's risk
assessments for HHT. Such comments and input could address, for
example, the availability of additional data to further refine the risk
assessments, such as inhalation toxicity and worker exposure data, or
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 HHT. Risks of concern associated with
the use of HHT are: HCHO residential handler (inhalation) and post-
application/bystander (inhalation), HCHO occupational handler
(inhalation), and HHT occupational handler (dermal). 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 HHT, 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

[[Page 21948]]

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 HHT, a modified, 4-Phase process
with 1 comment period and ample opportunity for public consultation
seems appropriate in view of its few complex issues. 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.
    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 HHT. 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.''
