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 copper 8-quinolinolate, and soliciting public comment on risk 
management ideas or proposals. Copper 8-quinolinolate is currently 
registered as an active ingredient and is used as an algaecide, 
bactericide and fungicide. EPA developed the risk assessment and risk 
characterization for copper 8-quinolinolate 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).
    Copper 8-quinolinolate is used as a materials preservative and as a 
wood preservative. The following materials contain copper 8-
quinolinolate as a preservative: Industrial textiles intended for the 
treatment of webbing, tenting, rope, canvas, leather, industrial 
cotton, industrial fabrics and clothing worn by the military. These 
textile uses are intended for military use. Other material preservation 
uses include in-can paint preservation, pulp and paperboard, kraft 
paper, adhesives and glues. Copper 8-quinolinolate is used as an 
industrial wood preservative to control sapstain and to protect against 
mold and mildew in soft-wood or hard-wood lumber. It can also protect 
against insect damage for wood used mainly above ground. As a wood 
preservative copper 8-quinolinolate is used as a wood surface coating 
(e.g., water repellents applied via brush, roller or spray). Copper 8-
quinolinolate is impregnated into wood via non-pressure (e.g., non-
pressure dipping/immersion) and pressure techniques (vacuum/empty-
cell). The products can be used on many different types of wood 
including green or fresh cut/debarked lumber, poles, posts, and 
timbers; manufactured wood products such as logs (e.g., log home 
construction), plywood and particle board (wood composites); dry 
lumber; and finished wood products such as millwork, shingles, siding, 
plywood and structural lumber. The majority of the products are 
intended for use at wood treatment facilities.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessment for copper 8-quinolinolate. Such comments and input could 
address, for example, the availability of additional data to further 
refine the risk assessments, such as wood leaching data; confirmatory 
data to support wood treatment use; confirmatory inhalation toxicity 
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 copper 8-quinolinolate. Risks of concern 
associated with the use of copper 8-quinolinolate are: Occupational 
handler exposure and risks of concern resulting from wood preservation 
(via brush, low pressure sprayer and liquid pump), paper preservation 
(via liquid pump and liquid pour), textile preservation (via liquid 
pour) and application of treated paint (via airless sprayer); 
residential application of treated paint (via airless sprayer); 
residential post-application risks of concern resulting from treated 
tents; residential post-application aggregate exposure and risks of 
concern resulting from treated outdoor surfaces, treated textiles and 
treated wood products. 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 copper 8-quinolinolate, 
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 copper 8-quinolinolate, 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 copper 8-quinolinolate. 
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

[[Page 37770]]

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 
was completed by August 3, 2006.
