2-Octyl-3 (2H)-isothiazolone (Octhilinone) Risk Assessment; 
Notice of Availability and Risk Reduction Options; Reopening of Comment 
Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's risk 
assessment(s), and related documents for the pesticide 2-octyl-3 (2H)-
isothiazolone (also known as octhilinone or OIT), and opens a public 
comment period on these documents. 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 
octhilinone 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.

DATES: Comments must be received on or before August 17, 2007.

ADDRESSES: Submit your comments, identified by docket identification 
(ID) number EPA-HQ-OPP-2007-0414, by one of the following methods:

recommends that you include your name and other contact information in 
the body of your comment and with any disk or CD-ROM you submit. 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. Electronic files should avoid the use of special characters, 
any form of encryption, and be free of any defects or viruses.
    Docket: All documents in the docket are listed in the docket index 
available in regulations.gov. To access the electronic docket, go to 
http://www.regulations.gov, select ``Advanced Search,'' then ``Docket

CBI or other information whose disclosure is restricted by statute. 
Certain other material, such as copyrighted material, is not placed on 
the Internet and will be publicly available only in hard copy form.

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. What Action is EPA taking?

    EPA is reopening the availability of the Agency's preliminary human 
health and ecological risk assessments, initially issued for comment 
through a Federal Register notice published on June 13, 2007 (72 FR 
32649) (FRL-8136-2). EPA developed the risk assessments and risk 
characterization for octhilinone 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). Octhilinone is used as a material 
preservative, as an industrial mildewcide for cooling tower and air 
washer water systems, and as a wood preservative.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for octhilinone. Risks of concern associated 
with use of octhilinone are: Occupational handler exposure and risks of 
concern resulting from plastics and vinyl preservation (via liquid pump 
and liquid pour), paint preservation (via liquid pump and liquid pour), 
wood preservation (via mixing, loading, high pressure/high volume 
spraying), professional painter application (via airless sprayer) and 
use of treated paint; residential application and post-application 
risks of concern resulting from treated paint, treated carpet, treated 
vinyl, treated clothing and treated mattresses; and residential 
aggregate exposure and risks of concern resulting from treated fabrics, 
clothing and polymers. 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, 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 octhilinone, a modified, 4-Phase process with 1 comment 
period and ample opportunity for public consultation seems appropriate 
in view of its refined 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 
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 octhilinone. 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 octhilinone RED.

III. 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.''
