Endosulfan, Fenarimol, Imazalil, Oryzalin, Sodium Acifluorfen, Trifluralin, and Ziram; Proposed Tolerance Actions
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
SUMMARY: EPA is proposing to revoke certain tolerances for the insecticide endosulfan, the fungicides fenarimol, imazalil, and ziram; and the herbicide trifluralin. Also, EPA is proposing to modify certain tolerances for the insecticide endosulfan, the fungicides fenarimol, imazalil, and ziram; and the herbicides sodium acifluorfen and trifluralin. In addition, EPA is proposing to establish new tolerances for the insecticide endosulfan, the fungicides fenarimol, imazalil, and ziram; and the herbicides oryzalin and trifluralin. The regulatory actions proposed in this document are part of the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and the tolerance reassessment requirements of the Federal Food, Drug, and Cosmetic Act (FFDCA) section 408(q), as amended by the Food Quality Protection Act (FQPA) of 1996. By law, EPA is required by August 2006 to reassess the tolerances that were in existence on August 2, 1996. No tolerance reassessments will be counted at the time of a final rule because tolerances in existence on August 2, 1996, that are associated with actions proposed herein were previously counted as reassessed at the time of the completed Reregistration Eligibility Decision (RED), Report of the Food Quality Protection Act (FQPA) Tolerance Reassessment Progress and Risk Management Decision (TRED), or Federal Register action.

What Can I do if I Wish the Agency to Maintain a Tolerance that the Agency Proposes to Revoke?
This proposed rule provides a comment period of 60 days for any person to state an interest in retaining a tolerance proposed for revocation. If EPA receives a comment within the 60-day period to that effect, EPA will not proceed to revoke the tolerance immediately. However, EPA will take steps to ensure the submission of any needed supporting data and will issue an order in the Federal Register under FFDCA section 408(f) if needed. The order would specify data needed and the time frames for its submission, and would require that within 90 days some person or persons notify EPA that they will submit the data. If the data are not submitted as required in the order, EPA will take appropriate action under FFDCA.
EPA issues a final rule after considering comments that are submitted in response to this proposed rule. In addition to submitting comments in response to this proposal, you may also submit an objection at the time of the final rule. If you fail to file an objection to the final rule within the time period specified, you will have waived the right to raise any issues resolved in the final rule. After the specified time, issues resolved in the final rule cannot be raised again in any subsequent proceedings.

Background
-
What Action is the Agency Taking?
EPA is proposing to revoke, remove, modify, and establish specific tolerances for residues of the insecticide endosulfan, the fungicides fenarimol, imazalil, and ziram; and the herbicides oryzalin, sodium acifluorfen, and trifluralin in or on commodities listed in the regulatory text.
EPA is proposing these tolerance actions to implement the tolerance recommendations made during the reregistration and tolerance reassessment processes (including follow-up on canceled or additional uses of pesticides). As part of these processes, EPA is required to determine whether each of the amended tolerances meets the safety standard of the FQPA. The safety finding determination of ``reasonable certainty of no harm'' is discussed in detail in each
[[Page 24617]]
Reregistration Eligibility Decision (RED) and Report of the Food Quality Protection Act (FQPA) Tolerance Reassessment Progress and Risk Management Decision (TRED) for the active ingredient. REDs and TREDs recommend the implementation of certain tolerance actions, including modifications to reflect current use patterns, meet safety findings, and change commodity names and groupings in accordance with new EPA policy. Printed copies of many REDs and TREDs may be obtained from EPA's National Service Center for Environmental Publications (EPA/ NSCEP), P.O. Box 42419, Cincinnati, OH 45242-2419, telephone 1-800-490- 9198; fax 1-513-489-8695; internet at http://www.epa.gov/ncepihom and

are available on the internet for endosulfan, fenarimol, imazalil, oryzalin, sodium acifluorfen, trifluralin, and ziram in public dockets EPA-HQ-OPP-2002-0262, EPA-HQ-OPP-2002-0250, EPA-HQ-OPP-2002-0217, EPA- HQ-OPP-2003-0369, EPA-HQ-OPP-2003-0293, EPA-HQ-OPP-2004-0142, and EPA- HQ-OPP-2004-0194, respectively, at http://www.regulations.gov.
The selection of an individual tolerance level is based on crop field residue studies designed to produce the maximum residues under the existing or proposed product label. Generally, the level selected for a tolerance is a value slightly above the maximum residue found in such studies. The evaluation of whether a tolerance is safe is a separate inquiry. EPA recommends the raising of a tolerance when data show that: (1) Lawful use (sometimes through a label change) may result in a higher residue level on the commodity and (2) the tolerance remains safe, notwithstanding increased residue level allowed under the tolerance. In REDs, Chapter IV on ``Risk management, Reregistration, and Tolerance Reassessment'' typically describes the regulatory position, FQPA assessment, cumulative safety determination, determination of safety for U.S. general population, and safety for infants and children. In particular, the human health risk assessment document which supports the RED describes risk exposure estimates and whether the Agency has concerns. In TREDs, the Agency discusses its evaluation of the dietary risk associated with the active ingredient and whether it can determine that there is a reasonable certainty (with appropriate mitigation) that no harm to any population subgroup will result from aggregate exposure.
Explanations for proposed modifications in tolerances can be found in the RED and TRED document and in more detail in the Residue Chemistry Chapter document which supports the RED and TRED. Copies of the Residue Chemistry Chapter documents are found in the Administrative Record and paper copies for endosulfan, fenarimol, imazalil, oryzalin, sodium acifluorfen, and trifluralin can be found under their respective public docket numbers, identified above. Paper copies for ziram and imazalil are available in the public docket for this proposed rule. Electronic copies are available through EPA's electronic public docket and comment system, regulations.gov athttp://www.regulations.gov. You
may search for this proposed rule under docket number EPA-HQ-OPP-2005- 0459, or for an individual chemical under its respective docket number, then click on that docket number to view its contents.
EPA has determined that the aggregate exposures and risks are not of concern for the above-mentioned pesticide active ingredients based upon the data identified in the RED or TRED which lists the submitted studies that the Agency found acceptable.
EPA has found that the tolerances that are proposed in this document to be modified, are safe, i.e., that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residues, in accordance with section 408(b)(2)(C). (Note that changes to tolerance nomenclature do not constitute modifications of tolerances). These findings are discussed in detail in each RED or TRED. The references are available for inspection as described in this document under SUPPLEMENTARY INFORMATION.
In addition, EPA is proposing to revoke certain specific tolerances because either they are no longer needed or are associated with food uses that are no longer registered under FIFRA. Those instances where registrations were canceled were because the registrant failed to pay the required maintenance fee and/or the registrant voluntarily canceled one or more registered uses of the pesticide. It is EPA's general practice to propose revocation of those tolerances for residues of pesticide active ingredients on crop uses for which there are no active registrations under FIFRA, unless any person in comments on the proposal indicates a need for the tolerance to cover residues in or on imported commodities or domestic commodities legally treated.
EPA is proposing to revoke specific tolerances for combined imazalil residues of concern on the fat, liver, meat, and meat byproducts of hogs because the Agency has concluded that there is no reasonable expectation of finite residues in or on the commodities associated with the tolerances, and therefore these tolerances are no longer needed.
The determinations that there are no reasonable expectations of finite imazalil residues of concern on the fat, liver, meat, and meat byproducts of hogs were made based on the Agency's conclusion that there are no current imazalil commodity uses which are significant feed items for hogs. (While there is an imazalil tolerance for citrus dried pulp, the Agency does not consider it to be a significant feed item for hogs). Because EPA determined that there is no reasonable expectation of finite residues, under 40 CFR 180.6 the imazalil tolerances for hog, fat; hog, liver; hog, meat; and hog, meat byproducts are no longer needed under the FFDCA and can be proposed for revocation.
-
Endosulfan. Currently, the tolerance expression for residues is defined in terms of endosulfan and its metabolite endosulfan sulfate in 40 CFR 180.182. Because the tolerance expression should reflect the alpha- and beta-isomers of the parent compound, EPA is proposing to modify the tolerance expression in 40 CFR 180.182 in order to specify the alpha- and beta-isomers of the parent. Also, EPA is proposing to remove the ``(N)'' designation from all entries to conform to current Agency administrative practice (``N'' designation means negligible residues).
Because no active registrations exist for use of endosulfan on globe artichokes, sugar beets, raspberries, safflower seeds, and sunflower seeds, the tolerances are no longer needed. Therefore, EPA is proposing in 40 CFR 180.182(a)(1) to revoke the tolerances for ``artichoke, globe''; ``beet, sugar, roots''; ``raspberry''; ``safflower, seed''; and ``sunflower, seed.''
Based on available data on almond that show combined endosulfan residues of concern are non-detectable in or on almond kernels, the Agency has determined that the tolerance on almond should be increased to 0.3 ppm, the combined limits of detection. Therefore, EPA is proposing to increase the tolerance in 40 CFR 180.182(a)(1) for combined endosulfan residues of
[[Page 24618]]
concern in or on ``almond'' from 0.2 to 0.3 ppm.
Based on available data on the grain and straw of barley and wheat that show combined endosulfan residues of concern as high as 0.30, 0.30, 0.35, and 0.38 ppm in/on barley grain, wheat grain, barley straw, and wheat straw, respectively, the Agency has determined that the tolerances on barley and wheat grain should be increased to 0.3 ppm and tolerances on barley and wheat straw should be increased to 0.4 ppm. Therefore, EPA is proposing to increase the tolerances in 40 CFR 180.182(a)(1) for combined endosulfan residues of concern in or on ``barley, grain'' and ``wheat, grain'' from 0.1 to 0.3 ppm, and ``barley, straw'' and ``wheat, straw'' from 0.2 to 0.4 ppm.
