Environmental Protection Agency (EPA).
This notice announces the availability of EPA's risk assessment, and related documents for the triazole fungicide triadimenol and for its free triazole metabolites, and opens a public comment period on these documents. The triazole fungicides, which include triadimenol, triadimefon, and propiconazole, and others, share the common metabolites 1,2,4-triazole, triazole alanine, and triazole acetic acid (also known as free triazoles). EPA has conducted an aggregate risk assessment for the free triazole metabolites to ensure that aggregate exposure and risk from these common metabolites meet the current safety standards. he public is encouraged to suggest risk management ideas or proposals to address the risks identified. EPA is developing a tolerance reassessment decision (TRED) for triadimenol through a modified, 4-Phase public participation process that the Agency uses to involve the public in developing pesticide reregistration and tolerance reassessment decisions. Through these programs, EPA is ensuring that all pesticides meet current health and safety standards.

A. What Action is the Agency Taking?
EPA is releasing for public comment its human health risk assessment and related documents for triadimenol, a triazole fungicide, and an aggregate risk assessment for the free triazole metabolites, and encouraging the public to suggest risk management ideas or proposals. Triadimenol is a systemic fungicide used as a seed treatment for barley, corn, cotton, oats, rye, sorghum, and wheat. In addition, other triazole fungicides, which may metabolize to triazole conjugates, are formulated into pharmaceutical products which are approved for use by the Food and Drug Administration (FDA).
Additionally, an import tolerance on bananas has been established. Tolerances are established for residues of triadimenol and its butanediol metabolite in/on various plant commodities and are regulated as metabolites of the fungicide triadimefon. EPA developed the risk assessment and risk characterization for triadimenol 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).
EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency's risk assessment for triadimenol and for the free triazole metabolites 1,2,4-triazoleole alanine, and triazole acetic acid. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, such as both acute and subchronic neurotoxicity studies, a Developmental Neurotoxicity (DNT) study, information on potential exposure to triazole conjugates from pharmaceutical products, and separate metabolism studies (seed treatment) to confirm residues of concern, 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 triadimenol. As there are no residential uses associated with triadimenol, the aggregate risk assessment includes exposure from food and drinking water only. Acute and chronic aggregate risks (food and drinking water) are below the Agency's level of concern for all population subgroups. The current risk assessment only addresses risks associated with residues of triadimenol resulting from the use of triadimenol as an active ingredient. There are additional exposures to triadimenol residues that result from the use of the active ingredient triadimefon, because triadimefon degrades to triadimenol, but those exposures have not been aggregated with exposures from the use of triadimenol alone because the risks associated with the active ingredient triadimefon are currently unacceptable. However, once the triadimefon risks have been refined or mitigated, EPA will conduct an aggregate assessment of the risks associated with triadimenol residues that result from the use of both active ingredients, triadimenol and triadimefon. In targeting these potential risks of concern, the Agency solicits comments on assumptions used in the current risk assessment as well as 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 Start Printed Page 7949triadimenol or its free triazole metabolites, 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 triadimenol, a modified, 4-Phase process with one comment period and ample opportunity for public consultation seems appropriate in view of its refined risk assessment and other factors. 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. The decisions presented in the TRED may be supplemented by further risk mitigation measures when EPA considers whether a cumulative assessment is necessary for the triazole group of pesticides.
-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 Triadimenol. 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.Start List of Subjects
