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.
