    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: For each of the pesticides subject to the actions listed in 
    this proposed rule, EPA has completed the reregistration process and 
    issued a Reregistration Eligibility Document (RED). In the 
    reregistration process, all information to support a pesticide's 
    continued registration is reviewed for adequacy and, when needed, 
    supplemented with new scientific studies. Based on the RED tolerance 
    assessments for the pesticide chemicals subject to this proposed rule, 
    EPA is proposing the following actions: to delete the term potassium 
    oleate from the tolerance exemption for ``potassium oleate and related 
    C12-C18 fatty acid potassium salts,'' to increase the 
    tolerance for oxytetracycline on peaches, and for the tolerance ``S-
    ethyl diisobutylthiocarbamate,'' to change the chemical name to the 
    common name ``butylate'', to delete certain terms, and to change 
    commodity definitions to accord with Table II of Subdivision O.

    I. Legal Authorization
    
        The Federal Food, Drug, and Cosmetic Act (FFDCA) [21 U.S.C. 301 et 
    seq.] authorizes the establishment of tolerances (maximum legal residue 
    levels) and exemptions from the [[Page 19557]] requirement of a 
    tolerance for residues of pesticide chemicals in or on raw agricultural 
    commodities pursuant to section 408 [21 U.S.C. 346(a)]. Without such 
    tolerances or exemptions, a food containing pesticide residues is 
    considered to be ``adulterated'' under section 402 of the FFDCA, and 
    hence may not legally be moved in interstate commerce [21 U.S.C. 342]. 
    To establish a tolerance or an exemption under section 408 of the 
    FFDCA, EPA must make a finding that the promulgation of the rule would 
    ``protect the public health'' [21 U.S.C. 346a(b)]. For a pesticide to 
    be sold and distributed the pesticide must not only have appropriate 
    tolerances under the FFDCA, but also must be registered under the 
    Federal Insecticide, Fungicide, and Rodenticide Act [FIFRA, 7 U.S.C. 
    136 et seq.].
        In 1988, Congress amended FIFRA and required EPA to review and 
    reassess the potential hazards arising from currently registered uses 
    of pesticides registered prior to November 1, 1984. As part of this 
    process, the Agency must determine whether a pesticide is eligible for 
    reregistration and if any subsequent actions are required to fully 
    attain reregistration status. EPA has chosen to include in the 
    reregistration process a reassessment of existing tolerances or 
    exemptions from the need for a tolerance. Through this reassessment 
    process, EPA can determine whether a tolerance must be amended, 
    revoked, or established, or whether an exemption from the requirement 
    of one or more tolerances must be amended or is necessary.
        The procedure for establishing, amending, or repealing tolerances 
    or exemptions from the requirement of tolerances is set forth in the 
    Code of Federal Regulations 40 CFR parts 177 through 180. Pursuant to 
    40 CFR 180.32, EPA is proposing the amendment of the following 
    tolerances. The Administrator of EPA or any person may initiate an 
    action proposing to establish, amend, revoke, or exempt a tolerance for 
    a pesticide registered for food uses. The proposal must explain the 
    grounds for such a proposed action and will be published as a public 
    notice. Each petition or request for a new tolerance, an amendment to 
    an existing tolerance, or a new exemption from the requirement of a 
    tolerance must be accompanied by a fee. Current Agency policy on 
    tolerance actions identified during the reregistration process is to 
    waive the payment of fees if the tolerance action concerns revision or 
    revocation of an established tolerance, or if the proposed exemption 
    from the requirement of a tolerance requires the concurrent revocation 
    of an approved tolerance. Comments submitted in response to the 
    Agency's published proposals are reviewed; the Agency then publishes 
    its final determination regarding the specific tolerance actions.
    
    II. Chemical-Specific Information and Proposed Actions
    
    A. Potassium Oleate: Deletion of Term
    
        1. Regulatory background. Prior to March 1989, the Agency 
    classified potassium salts of fatty acids [C12-C18 saturated 
    and unsaturated fatty acids], potassium laureate, potassium myristate, 
    potassium oleate, and potassium ricinoleate as separate active 
    ingredients. In March 1989, the Agency decided to treat all potassium 
    salts of fatty acids, and all combinations of these chemicals, as a 
    single active ingredient because these active ingredients tend to exist 
    as mixtures in pesticide products. In May 1992, EPA revisited its March 
    1989 decision. EPA concluded that for registration purposes only 
    potassium salts of C12-C18, saturated and unsaturated fatty 
    acids, would be treated as a single active ingredient and that any 
    other chain length (either shorter or longer) should be considered to 
    be a different active ingredient.
        Because of the generally low toxicity of potassium salts and the 
    acceptability of naturally occurring fatty acids in food, in 1982 EPA 
    determined that a tolerance is not needed to protect the public health 
    and established an exemption from the requirement of a tolerance for 
    potassium oleate and related salts of fatty acids (47 FR 1379).
        2. Proposed action. Currently, under 40 CFR 180.1068, EPA has 
    established exemptions from the requirement of tolerances for potassium 
    oleate and related C12-C18 fatty acids of potassium salts for 
    residues in or on all raw agricultural commodities. Because EPA now 
    treats all C12-C18 fatty acids of potassium salts as a single 
    active ingredient, and potassium oleate is a C18-fatty acid, a 
    separate term for potassium oleate is no longer needed. Therefore, EPA 
    proposes that the term potassium oleate be deleted from 40 CFR 
    180.1068.
    
    B. Oxytetracycline: Amendment of the Tolerance on Peaches
    
        1. Regulatory background. Tolerances of 0.35 and 0.1 ppm currently 
    exist for the bactericide/fungicide oxytetracycline in or on pears and 
    peaches, respectively, from foliar treatment or injection (40 CFR 
    180.337), The Agency's 1988 Registration Standard for oxytetracycline 
    concluded that EPA had adequate data to support registered uses on 
    pears and peaches, including nectarines. However, an evaluation of 
    available data indicate that residue uptake in peaches could exceed the 
    existing 0.1 ppm tolerance level but would be less than 0.35 ppm. 
    Therefore, EPA is proposing that the oxytetracycline tolerance for 
    peaches be increased from 0.1 ppm to 0.35 ppm.
        To determine whether a 0.35 ppm tolerance level is protective of 
    the public health, EPA considered the following information:
        a. A 2-year chronic feeding study in Osborne-Mendel rats with a No 
    Observed Effect Level (NOEL) of 3,000 ppm, approximately 150 milligrams 
    (mg)/kilogram (kg)/day (highest dose tested).
        b. A 2-year chronic feeding study in Sprague-Dawley rats with a 
    NOEL of 1,000 ppm, approximately 50 mg/kg/day (highest dose tested).
        c. A 2-year chronic feeding study in dogs with a NOEL of 10,000 
    ppm, approximately 250 mg/kg/day (highest dose tested).
        d. A mouse developmental toxicity study with a NOEL for maternal 
    and developmental toxicity at 2,100 mg/kg (highest dose tested).
        e. A dog study, undertaken to evaluate antimicrobial resistance to 
    oxytetracycline, with a NOEL of 2 ppm (approximately 0.05 mg/kg/day).
        In December of 1988, EPA completed a review of the available data 
    for oxytetracycline and concluded that there is no evidence of 
    carcinogenic effects in either the mouse or the rat study.
        The reference dose (RfD) is established at 0.005 mg/kg/body weight 
    per day based on a NOEL of 0.05 mg/kg body weight per day from the dog 
    feeding study. An uncertainty factor of 10 to account for intraspecies 
    variability was used.
        The theoretical maximum residue contribution (TMRC) from existing 
    tolerances is 0.000268 mg/kg/day; the proposed increase in the 
    tolerance would contribute 0.000054 mg/kg/day. Existing tolerances and 
    the proposed increase to the tolerance on peaches would utilize 5.35 
    percent of the RfD. The most highly exposed subgroup, non-nursing 
    infants (less than 1 year old), had a TMRC of 0.001391 mg/kg/day, 
    utilizing 27.81 percent of the RfD. The Agency believes that exposure 
    at these levels carries no appreciable risk.
        The nature of the residue is adequately understood and an adequate 
    analytical method, a microbiological assay, is available for 
    enforcement purposes. [[Page 19558]] 
        2. Proposed action. Based on the data and information presented 
    above, the Agency is proposing that the tolerance for peaches be 
    increased from 0.1 to 0.35 ppm. In proposing this action, EPA believes 
    that the tolerance level of 0.35 ppm for oxytetracycline residues in or 
    on peaches is protective of the public health.
    
    C. Amendment to 40 CFR 180.232
    
        1. Background. EPA has determined, as explained in the 
    Reregistration Eligibility Document issued September 1993, that there 
    are sufficient data to support the adequacy of the established S-ethyl 
    diisobutylthiocarbamate tolerances listed in 40 CFR 180.232.
        2. Proposed action. By this document, EPA proposes the following 
    actions:
        a. Amend the name S-ethyl diisobutylthiocarbamate in 40 CFR 180.232 
    to the common name ``Butylate'' so that the tolerance regulation may be 
    more easily located.
        b. Delete the term ``negligible residues'' in the tolerance entry 
    because the regulation specifies a tolerance level.
        c. Amend the commodity definitions listed in 40 CFR 180.232 to read 
    as follows to conform to commodity definitions currently used by EPA:
        i. ``Corn grain (including popcorn)'' is proposed to be revised to 
    ``Corn, field, grain'' and ``Corn, pop, grain.''
        ii. ``Fresh corn including sweet corn (kernels plus cob with husk 
    removed)'' is proposed to be revised to ``Corn, sweet (kernels plus cob 
    with husk removed).''
        iii. ``Corn forage and fodder including sweet corn, field corn, and 
    popcorn'' is proposed to be revised to ``Corn, field, fodder''; ``Corn, 
    field, forage''; ``Corn, pop, fodder''; ``Corn, pop, forage''; and 
    ``Corn, sweet, forage.''
    
    III. Public Comment Procedures
    
        Interested persons are invited to submit written comments, 
    information, or data in response to this proposed rule. Comments must 
    be submitted by May 19, 1995. Comments must bear a notation indicating 
    the document control number. Three copies of the comments should be 
    submitted to either location listed under the ADDRESSES unit of this 
    preamble.
        Information submitted as a comment concerning this document may be 
    claimed confidential by marking any or all of that information as 
    ``Confidential Business Information'' (CBI). Information so marked will 
    not be disclosed except in accordance with procedures set forth in 40 
    CFR part 2. A copy of a comment that does not contain CBI must be 
    submitted for inclusion in the public record. Information not marked 
    confidential may be disclosed publicly by EPA without prior notice.
        Any person who has registered or submitted an application for 
    registration of a pesticide, under FIFRA as amended, which contains any 
    of the ingredients listed herein, may request within 30 days after 
    publication of this document in the Federal Register that this proposal 
    be referred to an Advisory Committee in accordance with section 408(e) 
    of the FFDCA.
        Documents considered and relied upon by EPA pertaining to this 
    action, and all written comments filed pursuant to this proposed rule, 
    will be available for public inspection in Rm. 1132, Crystal Mall #2, 
    1921 Jefferson Davis Highway, Arlington, VA between 8 a.m. and 4 p.m., 
    Monday through Friday, except public holidays. Any person who has 
    registered, or who has submitted an application for registration under 
    FIFRA of any of the pesticide chemicals listed in this proposed rule, 
    may request that this proposal be referred to an advisory committee. 
    Such a request must be made within 30 days of the publication of this 
    proposal. To satisfy requirements for analysis specified by Executive 
    Order 12866 and the Regulatory Flexibility Act, EPA has analyzed the 
    impacts of this proposal. This analysis is available for public 
    inspection in Rm. 1132 at the Virginia address given above.
    
    IV. Regulatory Assessment Requirements
    
    A. Executive Order 12866
    
        Under Executive Order 12866 (58 FR 51735, October 4, 1993), the 
    Agency must determine whether the regulatory action is ``significant'' 
    and therefore subject to review by the Office of Management and Budget 
    (OMB) and the requirements of the Executive Order. Under section 3(f), 
    the order defines a ``significant regulatory action'' as an action that 
    is likely to result in a rule: (1) having an annual effect on the 
    economy of $100 million or more, or adversely and materially affecting 
    a sector of the economy, productivity, competition, jobs, the 
    environment, public health or safety, or State, local or tribal 
    governments or communities (also referred to as ``economically 
    significant''); (2) creating serious inconsistency or otherwise 
    interfering with an action taken or planned by another agency; (3) 
    materially altering the budgetary impacts of entitlements, grants, user 
    fees, or loan programs or the rights and obligations of recipients 
    thereof; or (4) raising novel legal or policy issues arising out of 
    legal mandates, the President's priorities, or the principles set forth 
    in this Executive Order.
        Pursuant to the terms of this Executive Order, it has been 
    determined that this proposed rule is not a ``significant regulatory 
    action,'' because it does not meet any of the regulatory-significance 
    criteria listed above.
    
    B. Regulatory Flexibility Act
    
        This proposed rule has been reviewed under the Regulatory 
    Flexibility Act of 1980 [Pub. L. 96-354; 94 Stat. 1164, 5 U.S.C. 601 et 
    seq.] and EPA has determined that it will not have a significant 
    economic impact on a substantial number of small businesses, small 
    governments, or small organizations.
        Accordingly, I certify that this proposed rule does not require a 
    separate regulatory flexibility analysis under the Regulatory 
    Flexibility Act.
    
    C. Paperwork Reduction Act
    
        This proposed regulatory action does not contain any information 
    collection requirements subject to review by OMB under the Paperwork 
    Reduction Act of 1980, 44 U.S.C. 3501 et seq.

    ------------------------------------------------------------------------
    
        4. Section 180.1068 is revised to read as follows:
    
    
    Sec. 180.1068  C12-C18 fatty acid potassium salts; exemption 
    from the requirement of a tolerance.

    salts are exempted from the requirement of a tolerance for residues in 
    or on all raw agricultural commodities when used in accordance with 
    good agricultural practice.
