    SUPPLEMENTARY INFORMATION: Rhone-Poulenc North America Chemicals, Inc., 
    CN 5255, Princeton, NJ 08543-5255 submitted pesticide petition (PP) 
    6E04665 to EPA requesting that the Administrator, pursuant to section 
    408(e) of the Federal Food Drug, and Cosmetic Act (FFDCA) (21 U.S.C. 
    346 a(e)), propose to amend 40 CFR 180.1001(c), (d) and (e) by 
    establishing an exemption from the requirement of a tolerance without 
    limitation for residues of maleic anhydride-diisobutylene copolymer, 
    sodium salt (CAS Reg. No. 37199-81-1), when used as an inert ingredient 
    (suspending agent and dispersing agent) in pesticide formulations 
    applied to growing crops or to raw agricultural commodities after 
    harvest, under 40 CFR 180.1001(c) and applied to animals under 40 CFR 
    180.1001(e), and deleting the current exemption from the requirement of 
    a tolerance with a use limitation of 3 percent under 40 CFR 1001(d) for 
    application to growing crops only.
        Inert ingredients are all ingredients that are not active 
    ingredients as defined in 40 CFR 153.125, and include, but are not 
    limited to, the following types of ingredients (except when they have a 
    pesticidal efficacy of their own): solvents such as alcohols and 
    hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
    acids; carriers such as clay and diatomaceous earth; thickeners such as 
    carrageenan and modified cellulose; wetting, spreading, and dispersing 
    agents; propellants in aerosol dispensers; microencapsulating agents; 
    and emulsifiers. The term ``inert'' is not to imply nontoxicity; the 
    ingredient may or may not be chemically active.
        The data submitted in the petition and other relevant material have 
    been evaluated. As part of the EPA policy statement on inert 
    ingredients published in the Federal Register of April 22, 1987 (52 FR 
    13305), the Agency set forth a list of studies which would generally be 
    used to evaluate the risks posed by the presence of an inert ingredient 
    in a pesticide formulation. However, where it can be determined without 
    that data that the inert ingredient will present minimal or no risk, 
    the Agency generally does not require some or all of the listed studies 
    to rule on the proposed tolerance or exemption from the requirement of 
    a tolerance for an inert ingredient. The Agency has decided that no 
    data, in addition to that described below, for maleic anhydride-
    diisobutylene copolymer, sodium salt will need to be submitted. The 
    rationale for this decision is described below.
        In the case of certain chemical substances that are defined as 
    ``polymers,'' the Agency has established a set of criteria which 
    identify categories of polymers that present low risk. These criteria 
    (described in 40 CFR 723.250) identify polymers that are relatively 
    unreactive and stable compared to other chemical substances as well as 
    polymers that typically are not readily absorbed. These properties 
    generally limit a polymer's ability to cause adverse effects. In 
    addition, these criteria exclude polymers about which little is known. 
    The Agency believes that polymers meeting the criteria noted above will 
    present minimal or no risk. Maleic anhydride-diisobutylene copolymer, 
    sodium salt conforms to the definition of polymer given in 40 CFR 
    723.250(b) and meets the following
    
    [[Page 36330]]
    
    criteria that are used to identify low risk polymers:
        1. Maleic anhydride-diisobutylene copolymer, sodium salt is not a 
    cationic polymer, nor is it reasonably anticipated to become a cationic 
    polymer in a natural aquatic environment.
        2. Maleic anhydride-diisobutylene copolymer, sodium salt contains 
    as an integral part of its composition the atomic elements carbon, 
    hydrogen, oxygen, and sodium.
        3. Maleic anhydride-diisobutylene copolymer, sodium salt does not 
    contain as an integral part of its composition, except as impurities, 
    any elements other than those listed in 40 CFR 723.250(d)(2)(ii).
        4. Maleic anhydride-diisobutylene copolymer, sodium salt is not 
    designed, nor it is reasonably anticipated to substantially degrade, 
    decompose or depolymerize.
        5. Maleic anhydride-diisobutylene copolymer, sodium salt is not 
    manufactured or imported from monomers and/or other reactants that are 
    not already included on the TSCA Chemical Substance Inventory or 
    manufactured under an applicable TSCA section 5 exemption.
        6. Maleic anhydride-diisobutylene copolymer, sodium salt is not 
    water absorbing polymer.
        7. The minimum number-average molecular weight of maleic anhydride-
    diisobutylene copolymer, sodium salt is 20,900 daltons. Substances with 
    molecular weights (MW) greater than 400 generally are not absorbed 
    through the intact skin, and substances with MW greater than 1,000 
    generally are not absorbed through the intact gastrointestinal (GI) 
    track. Chemicals not absorbed through the skin or GI tract generally 
    are incapable of eliciting a toxic response.
        8. Maleic anhydride-diisobutylene copolymer, sodium salt has a 
    number average molecular weight of 20,900 and an oligomer content less 
    than 2 percent below MW 500 and less than 5 percent MW 1000.
        Based on the above information and review of its use, EPA has found 
    that, when used in accordance with good agricultural practice, this 
    ingredient is useful and tolerance is not necessary to protect the 
    public health. Therefore, EPA proposes that the exemptions from the 
    requirement of a tolerance be established for this polymer as set forth 
    below.
        Any person who has registered or submitted an application for 
    registration of a pesticide, under the Federal Insecticide, Fungicide, 
    and Rodenticide Act (FIFRA) as amended, that contains any of the 
    ingredients listed herein, may request within 30 days after the 
    publication of this document in the Federal Register that this 
    rulemaking proposal be referred to an Advisory Committee in accordance 
    with section 408(e) of the FFDCA.
        Interested persons are invited to submit written comments on the 
    proposed regulation. Comments must bear a notation indicating the 
    docket number, [OPP-300425].
        A record has been established for this rulemaking under docket 
    number [OPP-300425] (including comments and data submitted 
    electronically as described below). A public version of this record, 
    including printed paper versions of electronic comments, which does not 
    include any information claimed as CBI, is available for inspection 
    from 8 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
    holidays. The public record is located in Room 1132 of the Public 
    Response and Program Resources Branch, Field Operations Division 
    (7506C), Office of Pesticide Programs, Environmental Protection Agency, 
    Crystal Mall #2, 1921 Jefferson Davis Highway, Arlington, VA.
        Electronic comments can be sent directly to EPA at:
    
        opp-Docket@epamail.epa.gov
    
    
        Electronic comments must be submitted as an ASCII file avoiding the 
    use of special characters and any form of encryption.
        The official record for this rulemaking, as well as the public 
    version, as described above will be kept in paper form. Accordingly, 
    EPA will transfer all comments received electronically into printed, 
    paper form as they are received and will place the paper copies in the 
    official rulemaking record which will also include all comments 
    submitted directly in writing. The official rulemaking record is the 
    paper record maintained at the address in the ``ADDRESSES'' at the 
    beginning of this document.
        The Office of Management and Budget has exempted this rule from the 
    requirements of section 2 of Executive Order 12866.
        This action does not impose any enforceable duty, or contain any 
    ``unfunded mandates'' as described in Title II of the Unfunded Mandates 
    Reform Act of 1995 (Pub. L. 104-4), or require prior consultation as 
    specified by Executive Order 12875 (58 FR 58093, October 28, 1993), 
    entitled Enhancing the Intergovernmental Partnership, or special 
    consideration as required by Executive Order 12898 (59 FR 7629, 
    February 16, 1994).
        Pursuant to the requirement of the Regulatory Flexibility Act (Pub. 
    L. 96-354, 94 Stat. 1164, 5 U.S.C. 601-612), the Administrator has 
    determined that regulations establishing new tolerances or raising 
    tolerance levels or establishing exemptions from tolerance requirements 
    do not have an economic impact on a substantial number of small 
    entities. A certification statement to this effect was published in the 
    Federal Register of May 4, 1981 (46 FR 24950).
