PPO also has nonfood uses for bird seeds, cosmetic articles, gums, ores, packaging, pigments, pharmaceutical materials, and discarded nut shells prior to disposal. EPA developed the risk assessment and risk characterization for PPO 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 Agency received a request from the Almond Board of California to extend the comment period. EPA is hereby extending the comment period, which was set to end on January 9, 2006, to February 8, 2006. This extension is being given based on the request to have additional time to address data gaps identified in the preliminary human health risk assessment. In particular, the Almond Board plans to gather and submit survey information on worker exposure during fumigation and post fumigation, the time between fumigation and consumption by the public, and to prepare and present residue dissipation data on almonds. Since this is the only public comment period, the Agency is allowing a 30 day extension. List of Subjects Environmental protection, Pesticides and pests. Dated: December 12, 2005.

EPA is releasing for public comment its human health and environmental E:\FR\FM\21DEN1.SGM 21DEN1 erjones on PROD1PC68 with NOTICES Federal Register / Vol. 70, No. 244 / Wednesday, December 21, 2005 / Notices fate and effects risk assessments and related documents for imazapyr, a imidazolinone pesticide, and soliciting public comment on risk management ideas or proposals. Imazapyr is a herbicide that provides residual control of a wide variety of annual and perennial weeds. EPA developed the risk assessments and risk characterization for imazapyr 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). Imazapyr is a systemic, non-selective, pre- and post-emergent herbicide used for the control of terrestrial annual and perennial grasses, broad-leaved herbs, woody species, and riparian and emergent aquatic species. It is registered for use on a variety of agricultural, commercial, and residential use sites, including corn, forestry sites, rights-ofway, fence rows, hedge rows, drainage systems, outdoor industrial areas, outdoor buildings and structures, domestic dwellings, paved areas, driveways, patios, parking areas, walkways, various water bodies (including ponds, lakes, streams, swamps, wetlands, and stagnant water), and urban areas. Imazapyr is formulated as a liquid, a wettable powder (including water soluble bags), and a granular. Application methods include aerial, groundboom, boat, and tractor-drawn spreader. Applications to smaller areas may be made with handheld equipment, including low-pressure handwand sprayers, backpack sprayers, sprinkling cans, and handgun sprayers. Application rates range from 0.014 pound active ingredient/acre (lb ai/acre) on corn, to 1.5 lb ai/acre on noncropped areas and aquatic sites. EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency’s risk assessments for imazapyr. Such comments and input could address the Agency’s risk assessment methodologies and assumptions as applied to this specific pesticide. For example, the availability of additional data to further refine the risk assessments, such as: Toxicity data for marine/estuarine fish and invertebrates following chronic exposure and reproductive effects to avian species. VerDate Aug<31>2005 15:25 Dec 20, 2005 Jkt 208001 Through this notice, EPA also is providing an opportunity for interested parties to provide risk management proposals or otherwise comment on risk management for imazapyr. Risks of concern associated with the use of imazapyr are to non-target terrestrial plants and aquatic vascular plants, and potential risks to endangered species (aquatic vascular plants, terrestrial and semi-aquatic monocots and dicots). 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 imazapyr, 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 imazapyr, 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 Unit I. of the SUPPLEMENTARY INFORMATION, and must be received by EPA on or before the closing date. Comments will become part of the Agency Docket for imazapyr. Comments received after the close of the comment period will be marked ‘‘late.’’ EPA is not required to consider these late comments. PO 00000 Frm 00022 Fmt 4703 Sfmt 4703 75801 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 enduse 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. List of Subjects Environmental protection, Pesticides and pests. Dated: December 14, 2005.

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 imazapyr, a 
imidazolinone pesticide, and soliciting public comment on risk 
management ideas or proposals. Imazapyr is a herbicide that provides 
residual control of a wide variety of annual and perennial weeds. EPA 
developed the risk assessments and risk characterization for imazapyr 
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).
    Imazapyr is a systemic, non-selective, pre- and post-emergent 
herbicide used for the control of terrestrial annual and perennial 
grasses, broad-leaved herbs, woody species, and riparian and emergent 
aquatic species. It is registered for use on a variety of agricultural, 
commercial, and residential use sites, including corn, forestry sites, 
rights-of-way, fence rows, hedge rows, drainage systems, outdoor 
industrial areas, outdoor buildings and structures, domestic dwellings, 
paved areas, driveways, patios, parking areas, walkways, various water 
bodies (including ponds, lakes, streams, swamps, wetlands, and stagnant 
water), and urban areas.
    Imazapyr is formulated as a liquid, a wettable powder (including 
water soluble bags), and a granular. Application methods include 
aerial, groundboom, boat, and tractor-drawn spreader. Applications to 
smaller areas may be made with handheld equipment, including low-
pressure handwand sprayers, backpack sprayers, sprinkling cans, and 
handgun sprayers. Application rates range from 0.014 pound active 
ingredient/acre (lb ai/acre) on corn, to 1.5 lb ai/acre on non-cropped 
areas and aquatic sites.
    EPA is providing an opportunity, through this notice, for 
interested parties to provide comments and input on the Agency's risk 
assessments for imazapyr. Such comments and input could address the 
Agency's risk assessment methodologies and assumptions as applied to 
this specific pesticide.
    For example, the availability of additional data to further refine 
the risk assessments, such as: Toxicity data for marine/estuarine fish 
and invertebrates following chronic exposure and reproductive effects 
to avian species.
    Through this notice, EPA also is providing an opportunity for 
interested parties to provide risk management proposals or otherwise 
comment on risk management for imazapyr. Risks of concern associated 
with the use of imazapyr are to non-target terrestrial plants and 
aquatic vascular plants, and potential risks to endangered species 
(aquatic vascular plants, terrestrial and semi-aquatic monocots and 
dicots). 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 imazapyr, 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 imazapyr, 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 Unit I. of 
the SUPPLEMENTARY INFORMATION, and must be received by EPA on or before 
the closing date. Comments will become part of the Agency Docket for 
imazapyr. 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.
