II. Background

A. What Action is the Agency Taking?

    EPA is releasing for public comment its human health and 
environmental fate and effects risk assessment(s) and related documents 
for octhilinone, and soliciting public comment on risk management ideas 
or proposals. Octhilinone is currently registered as an active 
ingredient and is used as an industrial mildewcide, microbiocide, 
fungicide and bacteriocide. EPA developed the risk assessment 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).
    The primary use sites for octhilinone are as a materials 
preservative, as an industrial mildewcide for cooling tower and air 
washer water systems, and as a wood preservative. Some examples of 
materials that can contain octhilinone include fabrics and textiles 
(e.g., furniture, auto-upholstery, footwear, carpet, carpet- backing, 
tents, awnings, canvas, linens, wall and window coverings, dust towels, 
bedding, mattresses, pet bedding, poll liners, automotive trim, roof 
liners, marine upholstery, pond liners, synthetic brooms, mops, air 
filter media); coatings (e.g., walls, paints, plasters, stuccos); 
sealants (e.g., grouts, caulks, joint cements); adhesives (e.g., 
wallpaper pastes, gelatin and starch based); rubber and plastics (e.g., 
latex, acrylic, styrene, butadiene, polyvinyl chloride, polymethane, 
vinyl, foams); leather preservation (e.g., wet processes). Octhilinone 
is also used for metalworking fluid preservation, hydraulic fluid 
preservation, and industrial process and water systems including air 
washer water and flow-thru cooling towers. As a wood preservative, 
octhilinone is used as an antisapstain drench to debarked logs.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessment for octhilinone. Such comments and input could address, for 
example, the availability of additional data to further refine the risk 
assessments, such as wood leaching data, environmental runoff 
monitoring data, soil Koc values and outstanding eco-toxicity data, 
which are all needed by the Agency to conduct an antisapstain wood 
treatment risk assessment; and confirmatory 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 octhilinone. Risks of concern associated 
with the 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 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 octhilinone, 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 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 one 
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.

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.
