    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: EPA is proposing this regulation under section 5 of the Toxic 
    Substances Control Act (TSCA), 15 U.S.C 2604, to screen microorganisms 
    before they are introduced into commerce. Under an interpretation EPA 
    issued in 1986 (51 FR 23302, June 26, 1986), ``new'' microorganisms are 
    those formed by deliberate combinations of genetic material from 
    organisms in different genera. This proposed rule is designed to 
    prevent unreasonable risk to human health and the environment without 
    imposing unnecessary regulatory burdens on the biotechnology industry. 
    This proposed regulation describes notification procedures and 
    microorganisms that would be exempt from notification.
    
    DATES: Written comments on this proposed rule should be received by 
    October 31, 1994.
        EPA may hold an informal hearing in Washington, DC, if EPA receives 
    written requests to hold a public hearing. For further information on 
    the hearing, see Unit IV.I. of this preamble. Written requests to make 
    an oral presentation should be submitted to the Environmental 
    Assistance Division by October 3, 1994 at the address below. Persons 
    are advised to call the Environmental Assistance Division after October 
    11, 1994 to ascertain if a hearing is to be held, and the date, time, 
    and location.

    I. Introduction
    
    A. Purpose of This Proposed Rule
    
        This document proposes procedures for EPA to screen new 
    microorganisms. EPA's goals in proposing these rules are to take into 
    account scientific uncertainties surrounding the behavior of these 
    microorganisms and avoid unreasonable risks to health and the 
    environment which may be associated with their use, to avoid imposing 
    unwarranted costs and restrictions on a promising industry, and to 
    establish a flexible review program that can adjust as the technology 
    evolves and matures.
        EPA will screen new microorganisms before they are manufactured for 
    general commercial use, or in some circumstances used for commercial 
    research and development (R&D) purposes, until sufficient familiarity 
    is gained with their behavior. As EPA acquires familiarity with new 
    microorganisms through reviews or other avenues, EPA expects certain of 
    these organisms to become eligible for reduced reporting or to be 
    eliminated from screening altogether.
        EPA recognizes the enormous potential of biotechnology to fight 
    disease, pollution, and hunger, and to replace some chemicals that are 
    harmful to the environment. The realization of these benefits depends 
    upon public confidence in the safety of biotechnology. Public 
    perception will strongly affect the conduct of field tests and the 
    acceptance of commercial applications of biotechnology (Ref. 1). At the 
    same time, EPA recognizes the importance of retaining the competitive 
    advantage the United States presently maintains in the development and 
    application of biotechnology. Recognizing that regulations can affect 
    competitiveness and public acceptance either negatively or positively 
    (Ref. 2), EPA is proposing rules that it believes balance the needs of 
    the public without adversely affecting the capacity for innovation.
    
    B. Role of This Proposed Rule in the Federal Coordinated Framework For 
    Regulation of Biotechnology
    
        This proposed rule implements EPA's program for oversight of 
    microorganisms in accordance with the Federal ``Coordinated Framework 
    for Regulation of Biotechnology; Announcement of Policy and Notice for 
    Public Comment'' which was published by the Office of Science and 
    Technology Policy (OSTP) on June 26, 1986 (51 FR 23302, 23313). EPA's 
    policies regarding use of its statutes to regulate biotechnology 
    products are published in the ``Statement of Policy: Microbial Products 
    Subject to the Federal Insecticide, Fungicide, and Rodenticide Act and 
    Toxic Substances Control Act'' (``1986 Policy Statement'') which was 
    published as part of the Coordinated Framework. EPA is currently 
    operating its biotechnology program under the 1986 Policy Statement.
        Prior to the 1986 Policy Statement, EPA issued a ``Proposed Policy 
    Regarding Certain Microbial Products'' on December 31, 1984 (49 FR 
    50880) (``1984 Proposed Policy Statement''). Subsequent to the 1986 
    Policy Statement, EPA issued a notice, entitled ``Biotechnology; 
    Request for Comment on Regulatory Approach'' on February 15, 1989 (54 
    FR 7027), in order to solicit comments on the direction of EPA's 
    program under TSCA. Comments on the 1984 and 1986 documents and the 
    February 15, 1989 Federal Register notice are addressed, as 
    appropriate, in this preamble.
        On September 7, 1990, EPA convened a subcommittee of its 
    Biotechnology Science Advisory Committee (Subcommittee on 
    Implementation of Scope) to comment on topics associated with this 
    proposed rule. EPA again convened a subcommittee, the Subcommittee on 
    the Proposed Biotechnology Rule under TSCA, which met on July 22, 1991. 
    Advice from both of these subcommittees has been incorporated as 
    appropriate in this preamble, and summaries of subcommittee 
    deliberations have been placed in the docket for this rulemaking. This 
    proposed rule announced today is intended to describe implementation of 
    EPA's program for regulation of microorganisms under TSCA.
    
    C. Statutory Framework
    
        This Unit describes the TSCA provisions used for this rulemaking.
        1. Jurisdiction. TSCA authorizes EPA to regulate any chemical 
    substance, except for certain substances covered by other Federal 
    agencies. The Act defines chemical substance broadly enough to cover 
    microorganisms. Specifically, section 3(2) of TSCA defines chemical 
    substance, in part, as any organic substance of a particular molecular 
    identity including any combination of such substances resulting in 
    whole or in part from a chemical reaction or occurring in nature.
        a. Organisms are chemical substances. The TSCA definition of 
    chemical substance describes any deoxyribonucleic acid (DNA) or 
    ribonucleic acid (RNA) molecule, however created, that is a component 
    of an organism's genetic material. Similarly, a microorganism is a 
    chemical substance, because it is a combination of substances of 
    particular identities that occur in nature or occur, in whole or in 
    part, as a result of a chemical reaction (Ref. 3). EPA has consistently 
    applied this definition to life forms and in the 1984 Proposed Policy 
    Statement (49 FR 50886-87) clarified that this interpretation applies 
    to microorganisms. While the statutory term ``chemical substance'' has 
    been interpreted to include microorganisms, EPA acknowledges that 
    microorganisms are not generally referred to as chemicals. Therefore, 
    throughout this preamble, the term ``traditional chemicals'' will be 
    used to refer to chemical substances other than microorganisms.
        The fact that microorganisms can be considered chemical substances 
    under TSCA only establishes EPA authority over them. Implementation of 
    that authority requires further action, either to interpret specific 
    terms or to issue rules. Discussion of the types of microorganisms 
    covered in this proposal can be found in Unit IV.A. of this preamble.
        b. Plants and animals are not subject to this proposed rule. Plants 
    and animals could also be chemical substances under TSCA. Nevertheless, 
    as a matter of policy, EPA has limited this rulemaking to 
    microorganisms, e.g., microalgae of the plant kingdom. Transgenic 
    plants and animals are not subject to requirements under this proposed 
    rule, either as whole organisms or when their cells or parts of cells 
    are cultured in vitro. However, microorganisms into which plant or 
    animal gene segments are intentionally incorporated would be considered 
    microorganisms potentially subject to TSCA. Traditional chemicals 
    extracted from a plant or animal also may be subject to TSCA, as are 
    other chemical substances. EPA is reserving authority under TSCA to 
    screen transgenic plants and animals in the future as needed.
        c. Microorganisms excluded by statute. The definition of ``chemical 
    substance'' in TSCA excludes pesticides, tobacco and tobacco products, 
    food, food additives, drugs (including human drugs, animal drugs, and 
    animal biologics), cosmetics, and substances that are used as medical 
    devices. These substances are regulated under other statutes by the EPA 
    Office of Pesticide Programs, the United States Department of 
    Agriculture (USDA), or the Food and Drug Administration (FDA).
        Certain microorganisms that are subject to TSCA but are also known 
    plant pests are regulated jointly by EPA under TSCA and the USDA under 
    the Federal Plant Pest Act. In cases where microorganisms are not known 
    to be plant pests, the microorganisms used for TSCA purposes would be 
    regulated solely by EPA. However, USDA would become involved if an EPA 
    review determined that the microorganism had plant pest qualities.
        d. Microorganisms used as intermediates. Microorganisms may be used 
    as intermediates to produce substances that are in turn used as 
    products subject to TSCA or other statutes. Under the Federal Food, 
    Drug, and Cosmetics Act (FFDCA), intermediates used to make products 
    subject to FFDCA are considered to be components of foods, food 
    additives, drugs, cosmetics and medical devices, as the case may be. 
    Therefore, those microorganism intermediates are excluded from 
    regulation under TSCA. All other intermediates, including pesticide 
    intermediates, are subject to TSCA jurisdiction. Traditional chemicals 
    not excluded from TSCA and produced by microorganism intermediates are 
    subject to TSCA section 5. These chemicals produced by microorganisms 
    are subject to the same requirements and procedures as chemicals 
    produced by other means. EPA discussed its approach to microorganism 
    intermediates and their products in its 1984 Proposed Policy Statement 
    (49 FR 50887, 50890; December 31, 1984).
        2. Application of TSCA section 5. TSCA gives EPA comprehensive 
    authority to regulate chemical substances and mixtures of chemical 
    substances under four major provisions. Section 4 authorizes the 
    issuance of rules requiring testing of chemicals. Section 6 authorizes 
    the Agency to issue substantive regulations to protect against 
    chemicals that present an unreasonable risk. Section 7 authorizes 
    protection against imminent hazards. EPA has based its biotechnology 
    rulemaking efforts on section 5, the other major TSCA provision. 
    Section 5 establishes a 90-day process for EPA to screen certain 
    chemical substances before they are produced. Within the 90 days 
    following receipt of notification, EPA has to decide whether to drop 
    the substance from further consideration or to impose controls.
        Section 5(a) allows EPA to require submission of a notification for 
    two types of microorganisms, those that are considered ``new'' chemical 
    substances and those that will be made for a ``significant new use.'' 
    In both cases, notification is not triggered by a determination that a 
    risk is present. Risk is fully considered during or after the screening 
    process. Those substances defined as ``new chemical substances'' are 
    automatically subject to notice requirements. Chemical substances which 
    are made for a significant new use are subject to notification when EPA 
    issues a rule for the particular substance.
        While the statute TSCA does not distinguish between the form or 
    content of the notifications for new substances or new uses, EPA's 
    current regulatory program, which is largely applicable to traditional 
    chemicals, does. The notification for a new chemical substance is 
    called a premanufacture notice (PMN). The notification for a 
    significant new use is called a significant new use notice (SNUN). For 
    the biotechnology program, however, EPA is proposing to refer to either 
    type of notification as a Microbial Commercial Activity Notice or MCAN.
        Notices under section 5(a) are submitted by manufacturers of new 
    chemical substances, and by persons who manufacture or process chemical 
    substances for a significant new use. TSCA section 3(7) defines 
    ``manufacture'' to mean import into the United States, production or 
    manufacture. Thus, the word manufacture as used in this preamble refers 
    to importation and any type of production, as well as to those 
    activities that may commonly be considered manufacture. TSCA section 
    3(10) defines ``process'' as preparation of a substance, after its 
    manufacture, for distribution in commerce.
        a. Distinction between ``commercial purposes'' and ``general 
    commercial use.'' TSCA section 5(i) limits section 5 screening to 
    activities ``for commercial purposes.'' The term ``commercial 
    purposes'' applies to all activities that derive actual or potential 
    commercial benefit for persons associated with those activities. This 
    includes R&D designed to result in a commercial product, whether or not 
    a product is actually developed. A discussion of various options for 
    EPA to decide what constitutes commercial purposes under this rule 
    appears at Unit III.A.
        These rules propose different review procedures for microorganisms 
    used for commercial R&D and for microorganisms that are no longer in 
    R&D and are intended for commercial distribution. In order to 
    distinguish between commercial R&D and other types of commercial 
    activity, EPA is describing use for commercial purposes beyond R&D as 
    ``general commercial use.''
        b. Definition of ``new.'' The term, ``new chemical substance,'' is 
    defined at TSCA section 3(9) as a substance not on the TSCA Inventory 
    of Chemical Substances (``Inventory'') manufactured in the United 
    States. Compilation and publication of the Inventory is a requirement 
    imposed on EPA by TSCA section 8(b). When EPA completes review of a new 
    substance, the substance is placed on the Inventory upon EPA's receipt 
    of a Notice of Commencement which indicates that production has begun. 
    At this point, the substance is no longer new, and subsequent producers 
    do not have to submit PMNs.
        EPA has a longstanding policy of not explicitly listing on the 
    Inventory unprocessed naturally occurring substances. Instead, these 
    substances are considered to be implicitly included on the Inventory 
    (see 40 CFR 710.4(b)). Thus, they are not ``new'' and do not require 
    PMNs.
        In defining what constitutes an unprocessed naturally occurring 
    substance, EPA has distinguished between substances isolated from 
    nature using more or less mechanical means and those isolated from 
    nature using more sophisticated forms of human intervention, such as 
    chemical reactions. The latter substances remove from a natural product 
    something that, by itself, does not exist in nature. One example is 
    that natural latex extracted from trees is a naturally occurring 
    substance, but the rubber formed after chemical coagulants are added is 
    not (42 FR 64589, December 23, 1977).
        EPA is retaining for this rulemaking its interpretation of ``new'' 
    microorganisms as discussed in the 1986 Policy Statement. Under that 
    interpretation, microorganisms resulting from deliberate, intergeneric 
    combinations of genetic material constitute ``new'' microorganisms 
    subject to PMN requirements. For the purposes of the Policy Statement, 
    the Agency defined intergeneric microorganisms as those formed by 
    deliberate combinations of genetic material from source organisms in 
    different genera. EPA may decide to reconsider its interpretation of 
    ``new'' microorganism at a later time and in aseparate rulemaking. EPA 
    requests comment on whether it should explore alternative 
    interpretations of ``new'' microorganism.
        In the 1986 Policy Statement, EPA excluded from the definition of a 
    ``new'' microorganism, those microorganisms that have resulted from the 
    addition of intergeneric material that is well-characterized and 
    contains only non-coding regulatory regions such as operators, 
    promoters, origins of replication, terminators, and ribosome-binding 
    regions. EPA is also proposing to retain this exclusion as part of its 
    interpretation of ``new'' microorganism.
        In the course of implementing the 1986 Policy Statement, the Agency 
    recognized that it had to develop additional guidance concerning the 
    definition of a new microorganism. It became apparent that a policy was 
    needed to address certain genetic elements which can be transferred 
    between microorganisms of different genera. These are termed mobile 
    genetic elements (MGEs) and include plasmids and transposons. EPA 
    developed additional guidance concerning whether microorganisms 
    modified using vectors that contained MGEs or parts of MGEs were 
    considered new. The Agency indicated that the major consideration is 
    the source of the original isolation of the MGE. EPA stated that 
    microorganisms would be considered ``new'' and thus subject to PMN 
    requirements, if the MGE was originally isolated from a microorganism 
    in a genus different from the recipient genus. Microorganisms would be 
    considered intrageneric, and hence not subject to PMN requirements, if 
    the MGE was originally isolated from a microorganism in the same genus 
    as the recipient.
        The Agency has adopted this interpretation for reasons of 
    regulatory clarity and uncertainty about the possibility of the 
    resulting microorganism exhibiting new traits. For example, some MGEs 
    may contain genetic material that normally is not expressed in one 
    microorganism but, when inserted into another microorganism, may be 
    expressed and result in a new trait. Since the Agency plans to continue 
    to use the 1986 Policy Statement interpretation of ``new'' to be 
    intergeneric microorganisms, the Agency will continue to use this MGE 
    guidance to clarify what microorganisms would be subject to TSCA 
    section 5 reporting. EPA specifically requests comments on whether the 
    MGE interpretation provides appropriate assistance for determining 
    whether a microorganism is intergeneric or whether additional 
    modifications which would be useful in clarifying which intergeneric 
    microorganisms should be reported under TSCA section 5.
        c. Significant new use. EPA determines a use is a significant new 
    use by issuing a rule. The rule is called a significant new use rule or 
    SNUR. Section 5(a)(2) sets forth some of the relevant considerations 
    for issuing a SNUR. The considerations generally include changes in the 
    type or form of exposure to a substance. Although EPA is not proposing 
    any specific SNURs in this rulemaking, EPA is proposing to set up 
    processes for issuing SNURs for microorganisms if needed in the future. 
    See Unit IV.C. of this preamble for a discussion of the proposed SNUR 
    processes.
        d. Section 5 regulatory mechanisms. If the 90-day period provided 
    for review of a PMN or SNUN expires and EPA has taken no action, 
    production of the substance may begin. However, within the review 
    period, EPA may prevent or limit production of the substance under 
    section 5(e) or 5(f). Under section 5(e) EPA may issue an order 
    prohibiting or limiting production of a substance, if the Agency 
    determines that information is insufficient and the substance may 
    present unreasonable risk or its use may result in substantial 
    exposure. If the notification submitter objects, the section 5(e) order 
    does not take effect and EPA may go to court to obtain an injunction to 
    accomplish the same goals as the section 5(e) order.
        Alternatively, if EPA finds that a substance presents or will 
    present an unreasonable risk, the Agency may, under section 5(f), go to 
    court for an order restricting or prohibiting production or issue an 
    administrative order or immediately effective rule to accomplish that 
    result.
        If EPA decides subsequent to Inventory listing that further 
    oversight is needed, the Agency may use other provisions of TSCA. These 
    could include SNURs or other rules that would require testing (TSCA 
    section 4), information submission (TSCA section 8) or substantive 
    restrictions (TSCA section 6).
        e. Exemptions from the section 5 notification process. Section 5(h) 
    provides for certain exemptions from screening. Three are relevant to 
    biotechnology. Section 5(h)(1) allows manufacturers or processors of 
    substances only for test marketing to apply to EPA for an exemption 
    from full notification. Unit II.C.3. of this preamble discusses the 
    test marketing exemption (TME) for microorganisms.
        Section 5(h)(3) provides that the screening mechanisms do not apply 
    to substances manufactured or processed only in ``small quantities'' 
    for R&D, provided that persons engaged in R&D activities for a 
    manufacturer are notified of any risks to health associated with the 
    substance. Section 5(h)(3) authorizes EPA to define by rule what 
    constitutes small quantities and to prescribe the form and manner of 
    risk notification. EPA is proposing a small quantities definition that 
    is limited to contained structure R&D uses of microorganisms. There 
    would be no small quantities exemption for microorganisms introduced 
    into the environment during commercial R&D, thus use of such 
    microorganisms must be reviewed. This modification is described at Unit 
    II.D. of this preamble. The rationale for this modification is 
    discussed at Unit III.B. of this preamble.
        Section 5(h)(4) allows EPA to exempt new substances from all or 
    part of section 5 screening requirements, if the Agency determines, by 
    rule, that such substances will not present an unreasonable risk. EPA 
    is proposing to use section 5(h)(4) to exempt certain categories of 
    microorganisms from screening as new microorganisms. Additionally, EPA 
    is proposing under section 5(h)(4) to allow R&D introductions of 
    microorganisms into the environment on the condition that EPA has 
    approved them through expedited review of information submitted in a 
    TSCA Experimental Release Application, or TERA. The TERA process is 
    described in Unit II.D. of this preamble. EPA is also proposing other 
    section 5(h)(4) exemptions for specific microorganisms and classes of 
    microorganisms as described in Unit II.C. of this preamble. The 
    rationale for all exemptions proposed under section 5(h)(4) appears in 
    Unit III.C. of this preamble.
        3. Substantial risk notification. Section 8(e) requires reporting 
    by manufacturers, processors and distributors who come across 
    information that their chemical substance could cause a ``substantial 
    risk.'' Section 8(e) is a self-implementing provision of TSCA. Thus, if 
    a manufacturer, processor or distributor of a microorganism finds 
    applicable information, that information must be submitted to EPA. Unit 
    IV.F. of this preamble discusses section 8(e) in further detail.
        4. Applicability of TSCA section 26. Section 26(c) authorizes EPA 
    to take any action under TSCA for a category of chemical substances. 
    EPA proposes to use this authority extensively in this rule. The 
    reasons for grouping microorganisms into categories, which include new 
    microorganisms used for R&D and certain new microorganisms manufactured 
    for general commercial use, are explained in applicable sections.
    
    II. Structure of the Proposed Rule
    
        This portion of the preamble discusses the major provisions of 
    these rules. The rationale supporting these provisions follows in Unit 
    III. Unit II.A. describes how to determine whether reporting is 
    required. Unit II.B. describes general administrative procedures that 
    would be applicable to all notices submitted. To facilitate 
    understanding of this proposed rule, requirements for microorganisms 
    manufactured for general commercial use are discussed separately from 
    those for microorganisms used for commercial R&D. Unit II.C. describes 
    procedures applicable to microorganisms which are manufactured for 
    general commercial use. Unit II.D. contains a similar description of 
    procedures applicable to microorganisms used for R&D.
        While these regulations are modelled after and incorporate many of 
    the procedures in the existing TSCA section 5 screening program for 
    traditional chemical substances which EPA has operated for the past 
    decade, modifications have been made, as appropriate, to address the 
    specific characteristics of microorganisms. In this respect, this 
    proposed rule incorporates well-established procedures which EPA has 
    adopted in previous rulemakings. The procedures are currently contained 
    in the Code of Federal Regulations (``CFR'') at parts 720 
    (premanufacture notification) and 721 (significant new use notification 
    requirements). EPA has decided, however, to establish a new part in the 
    CFR which applies specifically to microorganisms. EPA believes that 
    placing regulations affecting microorganisms screened under TSCA 
    section 5 in one place, part 725, will be more convenient and 
    efficient.
        EPA has only made changes to the procedures in parts 720 and 721 to 
    the extent required by unique characteristics of microorganisms. EPA is 
    therefore not soliciting comment on the procedures in proposed part 725 
    that are incorporated from parts 720 and 721.
        EPA will only consider comments to the extent they address the new 
    procedures and requirements in proposed part 725.
        In addition to a preferred approach for certain issues, this 
    preamble often contains a discussion of alternatives. EPA solicits 
    public comment on the preferred approaches and the alternatives 
    discussed in this document. Depending on public comment received on the 
    various proposals, any of these alternatives may be adopted in the 
    final rules.
    
    A. Determining Whether Reporting Is Required
    
        Manufacturers or processors would follow the process laid out below 
    to determine whether their microorganism is subject to reporting and, 
    if it is, how it would be treated under this proposed rulemaking. They 
    must first determine whether their microbial products are subject to 
    TSCA. Subpart A of part 725 contains the regulations applicable to this 
    determination. Many microorganisms are not subject to the requirements 
    of this proposed rule, because they are statutorily outside the 
    jurisdiction of TSCA. Statutory jurisdiction is discussed in Unit I.C. 
    of this preamble.
        1. Determining whether a microorganism is new or subject to a SNUR. 
    After manufacturers of microorganisms determine that their products are 
    subject to TSCA, they must determine whether the microorganisms are 
    new. Section 725.3 defines a new microorganism as one that is not 
    included on the Inventory. Microorganisms may be either implicitly or 
    explicitly included on the Inventory.
        a. Implicit inclusion. In its 1986 Policy Statement, EPA stated 
    that intergeneric microorganisms were the only microorganisms that 
    would not be implicitly included on the Inventory. As discussed in Unit 
    I.C. of this preamble, EPA will continue to use the 1986 Policy 
    Statement interpretation for this rulemaking.
        b. Explicit listing. A microorganism is not new, if it is 
    explicitly listed or implicitly included on the Inventory. 
    Microorganisms are placed on the Inventory if they have been previously 
    manufactured in the United States for general commercial use. EPA 
    explicitly lists microorganisms that it has previously reviewed, after 
    it is informed that production has begun through receipt of a Notice of 
    Commencement of Manufacture (NOC) (see Sec. 725.190). If a 
    microorganism is not considered to be implicitly included on the 
    Inventory, the public Inventory needs to be consulted to determine 
    whether the microorganism is explicitly listed. Microorganisms may also 
    be explicitly listed but treated as confidential and not placed on the 
    public Inventory.
        c. SNUR listing. After persons determine that their microorganisms 
    are included on the Inventory, they must then check to see if the 
    microorganisms are subject to a SNUR. Where appropriate, microorganisms 
    subject to SNURs will be identified, both on the Inventory and in 
    Subpart M of part 725. The SNUR process is discussed in Unit IV.C. of 
    this preamble.
        2. Consulting EPA when microorganism identity or use is 
    confidential or uncertain. Specific situations arise under these rules 
    when persons would need to consult listings of microorganisms to 
    determine whether a particular microorganism, or use of a 
    microorganism, is subject to reporting. These listings include the 
    Inventory; Subpart M of part 725, which lists significant new use 
    rules; and Sec. 725.239, which lists certain microorganisms exempt from 
    R&D reporting under part 725. The listings are explained in the text of 
    the regulation.
        There would be two specific circumstances under which it may not be 
    possible to determine whether a particular microorganism is listed. 
    First, the actual identity or use may be claimed confidential by a 
    person who originally manufactured or processed the microorganism. In 
    this case, a so-called generic name or use would appear on the public 
    Inventory, and the actual identity or use would be on a confidential 
    listing not available to the public. Unit IV.D. on Confidential 
    Business Information (CBI) explains the generic name and use. The 
    second circumstance would be that a non-confidential identity of a 
    microorganism may not be precise enough for a person to determine 
    whether it describes a particular microorganism that could be subject 
    to reporting. This circumstance may arise because of the imprecision of 
    scientific nomenclature in biology, particularly in microbiology, or 
    because similarities in modified genetic material may raise questions 
    of equivalency (see Unit IV.B.).
        To assist persons in determining their reporting obligations, EPA 
    has established a procedure whereby a person may file a submission 
    establishing a bona fide intent to manufacture or process a 
    microorganism and request that the Agency determine whether that 
    microorganism is on the applicable listing. EPA's goal is to respond in 
    30 days to the request, informing the requestor whether there is an 
    obligation to report under these regulations (see Sec. 725.15). This 
    procedure allows EPA to ensure appropriate reporting while maintaining 
    the confidentiality of legitimate trade secrets. This is a well-
    established procedure in the Agency's current regulations on TSCA 
    section 5 reporting (see Secs. 720.25 and 721.11). This preamble will 
    note when this process, known as a ``bona fide,'' applies.
    
    B. General Administrative Procedures
    
        After submitters determine that they have a microorganism subject 
    to TSCA section 5, they must determine what type of submission will 
    satisfy their reporting obligations. The first decision is whether the 
    microorganism will be used for R&D or general commercial use. The 
    specifics of the submission and review processes for general commercial 
    use and for R&D are covered in Units II.C. and II.D. of this preamble, 
    respectively. However, some administrative procedures apply generally 
    to all microorganism submissions. Therefore, general administrative 
    procedures are discussed in this Unit.
        Subpart B of part 725 contains administrative procedures generally 
    applicable to all submissions. Most of these are rather mechanical, 
    such as general recordkeeping requirements, procedures for determining 
    whether submissions are complete and properly filed, how to determine 
    when the Agency will begin the review period designated for a 
    particular submission, and under what circumstances the Agency or the 
    submitter may suspend, extend, or terminate a review. The more 
    important administrative procedures are discussed in this Unit.
        1. Prenotice consultation. EPA recommends that potential submitters 
    begin discussions with EPA staff early in the submission planning 
    process to identify any special data requests and preliminary concerns 
    that may be associated with the microorganism. This may save 
    significant time later in the review process. Any meetings and relevant 
    written communications may be claimed confidential. Persons who are 
    unsure as to whether their microorganisms are subject to any of the 
    requirements of part 725 should consult with EPA before preparing any 
    submission.
        With reference to R&D, EPA recognizes that research proceeds 
    through various stages. Potential submitters may find it advantageous 
    to begin discussions with EPA as early as the grant proposal stage, 
    even though they would not be required to file a submission under part 
    725 until the latter stages of their research program. Early 
    consultation with the Agency could assist submitters in the planning 
    stages of their research program in addition to providing a smoother 
    submission and review process.
        2. Submission process. The general requirements pertaining to the 
    submission process are found at Secs. 725.25 through 725.36.
        a. Preparing submissions. The data to be included in submissions 
    for microorganisms would be different from those for traditional 
    chemicals, because microorganisms may pose different risks than those 
    posed by traditional chemicals. To assist persons preparing submissions 
    under this proposed rule, EPA has developed a special guidance document 
    entitled ``Points to Consider in the Preparation and Submission of TSCA 
    Notifications for Microorganisms.'' At this time, a special form has 
    not been developed for microorganism submissions. Therefore, persons 
    preparing microorganism submissions should follow the format outlined 
    in the guidance document. This document is available from the 
    Environmental Assistance Division (see the address listed under the FOR 
    FURTHER INFORMATION CONTACT Unit).
        The regulatory text describes the type of information that is 
    relevant for each specific type of submission. Submitters should submit 
    all reasonably ascertainable information which they believe will assist 
    EPA in evaluating the microorganisms, including information not 
    specifically listed that submitters believe will be useful for EPA's 
    risk assessment. When information listed in the regulatory text is not 
    submitted, a brief explanation of why such information is not available 
    or not applicable should be included. Prenotice consultation may assist 
    in identifying specific information appropriate for a submission.
        b. Incomplete submissions. After an initial evaluation, EPA may 
    determine that a submission is incomplete and that the review period 
    cannot begin (see Sec. 725.33 of the regulatory text). If EPA finds the 
    submission incomplete, EPA will notify the submitter within 30 days of 
    receipt of the submission and will provide the submitter with an 
    opportunity to provide additional information. If the submitter 
    promptly provides additional information sufficient to evaluate the 
    effects of the microorganism, the evaluation will not be delayed beyond 
    time for a reasonable consideration of the new information. Otherwise, 
    EPA may declare the submission incomplete and the review period will 
    not begin until EPA receives the necessary information.
        3. Review process. The requirements pertaining generally to the 
    review process are found at proposed Secs. 725.40 through 725.60.
        a. Public involvement. EPA is aware that there is considerable 
    public interest in the review of submissions involving new 
    microorganisms and is committed to keeping the process as open as 
    possible. Following receipt of a submission, EPA is required by TSCA to 
    issue a notice in the Federal Register describing the submission (see 
    Sec. 725.40 of the regulatory text). The Federal Register notice would 
    include nonconfidential information on such items as the identity of 
    the microorganism, the type of use, occupational exposure, production 
    volume, a summary of test data included in the submission, and the 
    submitter's identity. If microorganism identity and use are claimed 
    confidential, EPA includes generic descriptions of this information in 
    the Federal Register notice. Unit IV.D. of this preamble discusses 
    confidentiality and generic descriptions. EPA would maintain a 
    nonconfidential copy of the submission in the TSCA Nonconfidential 
    Information Center for public inspection. The public will have an 
    opportunity to comment on submissions received by EPA. The length of 
    the comment period may be affected by the need to hold a meeting of 
    experts to address a particular submission, or to consider novel 
    scientific issues raised by the submission.
        b. State coordination. EPA has developed comprehensive procedures 
    to coordinate reviews of submissions and to share scientific 
    information to the fullest extent with appropriate State and local 
    authorities. For example, under EPA's current procedures for review of 
    field tests under the 1986 Policy Statement, within the first week of 
    receipt of a submission, an EPA review coordinator contacts by 
    telephone the appropriate regulatory agencies in the State(s) where the 
    test will be conducted to inform them of the submission. If requested, 
    a nonconfidential copy of the submission is mailed to the State. If a 
    site visit is to be conducted, EPA staff contacts State and EPA 
    regional personnel early in the review period to begin coordination of 
    the site visit. Nonconfidential reports, assessments, and public 
    comments added to the Public Docket are routinely made available to 
    State personnel upon request. In addition, State personnel receive a 
    copy of EPA's draft risk assessment, and comments and concerns raised 
    by the State(s) are given careful attention in the risk assessment. At 
    the conclusion of the review period, State personnel receive a copy of 
    any document which addresses the conditions under which the field test 
    can be performed.
        EPA is also requiring that persons who are preparing submissions 
    for R&D activities provide evidence of having notified appropriate 
    State authorities (see Sec. 725.255 of the regulatory text). Submission 
    of copies of any correspondence with State authorities concerning the 
    proposed field trial, for example, would satisfy this requirement. EPA 
    also strongly encourages such submitters to inform communities located 
    near potential test sites of their plans to introduce microorganisms 
    into the environment.
        c. Use of experts. In performing assessments, EPA intends to 
    supplement its staff expertise as necessary by using experts from other 
    government agencies, academia, and other independent sources. EPA 
    assessments may be reviewed by a subcommittee, composed of scientists 
    with relevant expertise, of EPA's Biotechnology Science Advisory 
    Committee (BSAC) at a public meeting. Certain portions of the meetings 
    may be closed to discuss confidential business information (CBI). EPA 
    will consider all BSAC Subcommittee recommendations in its final 
    decisions. Procedures have been developed to ensure that experts 
    contributing to EPA's biotechnology reviews will not have conflicts of 
    interest.
        d. Changes to the review process. The review period starts on the 
    date EPA determines the submission is complete and runs for a period of 
    time specified for each submission type. A submitter may voluntarily 
    withdraw a submission at any time, or suspend the review period for a 
    specified period of time. Suspension of the review period may be 
    beneficial when questions that arise during the notice review period 
    require additional time to address. For good cause, EPA may extend the 
    review period up to a total of the length of time specified for each 
    type of submission.
        4. Recordkeeping and compliance. The requirements for 
    recordkeeping, compliance, and inspections are found at Secs. 725.65, 
    725.70, and 725.75, respectively. In addition to recordkeeping 
    requirements generally applicable to all submissions, EPA is proposing 
    recordkeeping requirements specific to each submission type. For 
    certain exemptions from full reporting under section 5, the 
    recordkeeping requirements are a key part of compliance with the 
    exemption. Compliance and inspection requirements are the same as those 
    for traditional chemicals.
        5. Petitions to exempt new microorganisms. Provisions for 
    applications to request exemptions for new microorganisms from the 
    requirements of all or part of part 725 are found at Sec. 725.67.
    
    C. Reporting General Commercial Use of TSCA Microorganisms
    
        This Unit discusses who is subject to microbial commercial activity 
    notice (MCAN) reporting, the MCAN submission and review process, and 
    exemptions from MCAN reporting for general commercial use.
        1. Determining whether MCAN reporting is required. Subpart D of 
    part 725 would require, with some exceptions, submission of a MCAN by 
    persons who intend to manufacture or import new microorganisms, and by 
    persons who intend to manufacture, import, or process microorganisms 
    for a significant new use. A MCAN must be submitted 90 days before 
    manufacture, import, or processing of the microorganism for commercial 
    purposes. Because EPA has a separate, less burdensome, screening 
    process for R&D involving microorganisms (see Unit II.D. of this 
    preamble), the Agency expects that, in general, the MCAN will be 
    submitted only for microorganisms for general commercial use.
        2. MCAN submission and review process--a. MCAN submission process. 
    The purpose of EPA's review of MCANs would be similar to EPA's purpose 
    in reviewing PMNs and SNUNs submitted for traditional chemical 
    substances. The purpose of a MCAN would be to provide EPA with 
    information necessary to identify and list a microorganism on the TSCA 
    Inventory (if the microorganism is new) and to determine whether the 
    microorganism would pose an unreasonable risk to human health or the 
    environment. EPA must conduct a review that considers all the 
    reasonably ascertainable information on potential human health and 
    environmental effects of a microorganism. The information to be 
    included in the MCAN is listed in Secs. 725.155 and 725.160 of subpart 
    D. Submitters must develop a MCAN that describes the characteristics 
    and construction of the new microorganism as well as describing 
    conditions of manufacture and use. In addition, submitters must 
    reference any published literature on the microorganism and its 
    parental strains and submit available data from laboratory, greenhouse 
    studies, and/or R&D field tests using the microorganism.
        b. MCAN review process. All reviews of microorganisms will follow 
    established administrative steps that are the same for all chemical 
    substances subject to 90-day review. For good cause, EPA may extend the 
    initial review period by an additional 90 days, for a total of 180 
    days. During this time the microorganism cannot be manufactured or 
    processed for commercial purposes.
        c. Regulatory decision. EPA may reach one of three decisions during 
    the review period based on a balancing of the risks and benefits 
    presented by the microorganism: There is sufficient information to 
    determine that the risks will not be unreasonable; there is sufficient 
    information to determine that the risks are unreasonable; or there is 
    insufficient information to make a reasoned evaluation of risk, and the 
    substance may present an unreasonable risk or there may be significant 
    or substantial human or environmental exposure to it.
        Unless EPA notifies the submitter to the contrary, the submitter 
    may begin to manufacture and use the microorganism at the end of the 
    90-day period. However, if the information available is insufficient to 
    reasonably evaluate the risk and the substance may present an 
    unreasonable risk, EPA may issue an order under TSCA section 5(e) to 
    limit or prohibit the manufacture, processing, distribution in 
    commerce, use, or disposal of the microorganism. In the past, EPA has 
    found it useful to negotiate with submitters to develop consent orders, 
    sparing both the submitter and EPA the legal proceedings that may be 
    involved in a unilaterally issued order. Under a consent order, the 
    submitter generally agrees to develop additional information or to 
    accept certain restrictions in return for permission to proceed with 
    its plans to manufacture or import the substance.
        In the situation where EPA decides that risks will be unreasonable, 
    it may use TSCA section 5(f) to require measures to reduce risks to an 
    acceptable level as a condition of manufacture and use. Alternatively, 
    EPA may prohibit manufacture or use, if there are no measures available 
    or practicable to sufficiently reduce the risk.
        3. Exemptions from MCAN reporting. Persons intending to manufacture 
    new microorganisms for general commercial use may not have to submit a 
    MCAN prior to commencing manufacture, if the microorganisms they intend 
    to use qualify for exemptions from MCAN reporting. This unit discusses 
    one exemption developed for traditional chemicals that will not be 
    applied to microorganisms and two exemptions that are applicable to 
    microorganisms.
        a. Low volume exemption. EPA has previously promulgated rules 
    providing for an exemption from the notification requirements of 
    section 5 of TSCA for new chemical substances produced for general 
    commercial use in volumes less than 1,000 kilograms per year (see 40 
    CFR 723.50). This exemption requires applicants to submit a notice to 
    EPA 21 days before manufacture begins to provide the Agency an 
    opportunity to review the chemical. EPA believes that this exemption is 
    inappropriate for microorganisms, which have the ability to reproduce, 
    disseminate, and transfer genetic material. EPA is therefore proposing 
    to amend Sec. 723.50 to state that the exemption provisions of that 
    section do not apply to microorganisms.
        b. Test marketing exemption. Test marketing activities usually 
    involve limited sale or distribution of a substance within a 
    predetermined period of time to determine its competitive value when 
    its market is uncertain. EPA is required by TSCA section 5(h)(6) to 
    grant or deny the test marketing exemption (TME) no later than 45 days 
    after receipt of an application. Subpart F of part 725 proposes the 
    requirements for obtaining a TME. These requirements are adopted 
    verbatim from Sec. 720.38, the Agency regulations that currently apply 
    to all chemicals substances.
        In general, EPA suggests that manufacturers who intend to test 
    market new microorganisms file a MCAN rather than a request for a TME. 
    However, there may be situations in which this exemption may be 
    appropriate, such as for microorganisms which were previously reviewed 
    by EPA at the R&D stage. EPA encourages anyone who is considering 
    requesting a TME for a new microorganism to begin prenotice 
    consultation as early as possible, so that EPA can determine if it 
    would have sufficient information to determine that the test marketing 
    activities would not present an unreasonable risk.
        c. Tiered exemption for general commercial use. Under TSCA section 
    5(h)(4), EPA is proposing to exempt from MCAN requirements certain new 
    microorganisms manufactured for general commercial use which it has 
    determined will not present an unreasonable risk. Subpart G of part 725 
    contains the conditions for this exemption, which consists of two 
    tiers, each based on certain criteria discussed below. The rationale 
    for this exemption appears in Unit III.C.7. of this preamble. 
    Microorganisms produced under this exemption would not be listed on the 
    Inventory.
        (i) Tier I. Manufacturers meeting Tier I requirements will be 
    completely exempt from review by EPA. They would submit a one-time 
    certification statement to EPA 30 days prior to the first use of a 
    microorganism eligible for a Tier I exemption. The conditions for this 
    exemption are listed at Sec. 725.424. The statement must include 
    information identifying the manufacturer or importer, the location of 
    the facility involved, and a statement certifying that the manufacturer 
    complies with all the criteria required for the Tier I exemption. 
    Information in the statement may be claimed confidential. A 
    certification would be required for the first use of an eligible 
    recipient microorganism at a specific facility. Subsequent uses of the 
    same recipient microorganism at the same facility would not require 
    additional certification, so long as the manufacturer complied with the 
    other Tier I exemption conditions.
        (ii) Tier II. Manufacturers meeting the requirements at proposed 
    Sec. 725.428 may submit an exemption request to EPA 45 days prior to 
    use of the microorganisms, if they believe that containment conditions 
    other than those listed at proposed Sec. 725.422 would still allow the 
    requirements of the exemption to be met (see Sec. 725.455 of the 
    regulatory text). Information included in such a submission may be 
    claimed confidential. Submitters must certify in the request that they 
    have complied with the requirements. EPA would approve or deny an 
    exemption request within 45 days and could impose restrictions to 
    ensure that the microorganisms would not present an unreasonable risk 
    (see Sec. 725.470 of the regulatory text).
        (iii) Criteria for the exemption. Three conditions are placed on 
    the Tier I and Tier II exemptions. The recipient microorganisms must be 
    listed at proposed Sec. 725.420, the introduced genetic material must 
    meet certain requirements, and performance-based criteria for 
    containment and inactivation of the new microorganisms are to be used.
        (A) Recipient microorganisms. EPA is proposing that new 
    microorganisms certified to be developed using a recipient species or 
    strain listed at proposed Sec. 725.420 would qualify for the tiered 
    exemption.
        (B) Introduced genetic material. The introduced genetic material 
    used to modify the recipient microorganisms must be well characterized, 
    limited in size to the genetic material required to perform the 
    intended function, and poorly mobilizable (see Sec. 725.421 of the 
    regulatory text). Further explanation of these terms appears in Unit 
    III.C.7. of this preamble. In addition, genetic material which encodes 
    for all or part of the toxins listed in proposed Sec. 725.421(d) may 
    not be used to modify any recipient microorganism.
        (C) Containment and inactivation. EPA is also proposing 
    performance-based criteria for limiting exposures. These criteria would 
    have to be used for the Tier I exemption, because EPA would not review 
    these activities prior to production. For the Tier II exemption, 
    because the containment and inactivation controls would be reviewed in 
    the exemption request, the criteria would serve as guidance for 
    submitters. Proposed Sec. 725.422 lists the criteria for containment 
    and inactivation at a facility.
        (iv) Exemption applications. Using the provisions in proposed 
    Sec. 725.67, individuals may submit an application under section 
    5(h)(4) requesting that a recipient microorganism be added to the 
    exempt list. Submitters may request an exemption with different 
    conditions. EPA would evaluate the request using appropriate procedures 
    under section 5(h)(4).
    
    D. Reporting R&D Activities for TSCA Microorganisms
    
        This Unit discusses EPA's proposal for which microorganisms are 
    subject to R&D reporting and recordkeeping, exemptions from R&D 
    reporting, and the TSCA experimental release application (TERA) 
    submission and review process.
        1. Overview of considerations for determining whether a researcher 
    has TSCA section 5 obligations for R&D activities. Persons planning to 
    conduct R&D activities involving new microorganisms subject to TSCA may 
    be subject to these rules. While any researcher may submit a complete 
    MCAN as required for general commercial use, EPA is proposing a number 
    of exemptions from MCAN reporting that reduce researchers' reporting 
    obligations under TSCA section 5. All R&D activities are eligible for 
    reporting using the TERA process which is discussed below. However, EPA 
    expects that the TERA will be used primarily for environmental 
    experiments. Laboratory and other research in contained structures 
    would more likely comply with certain recordkeeping requirements 
    provided under TSCA section 5(h)(3) in the rule. Finally, certain 
    research may be exempt from TSCA section 5, because EPA has determined 
    review is unnecessary altogether or it is appropriate to defer in 
    whole, or in part, to another Federal agency.
        The series of considerations to be used to determine TSCA section 5 
    obligations for R&D activities is displayed in chart form in Figure 1 
    below. The following paragraphs summarize the steps on Figure 1.
        The first three steps list the issues that must be addressed for 
    determining if any substance is subject to TSCA section 5 reporting, 
    whether for general commercial use or for R&D activities. The 
    subsequent steps are employed to determine R&D obligations. Determining 
    whether an R&D activity is subject to TSCA jurisdiction and whether the 
    microorganism is intended for commercial purposes are discussed below 
    in Units II.D.2.a. and 2.b., respectively. Determining whether a 
    microorganism is ``new'' for the purposes of TSCA section 5 is 
    discussed in Unit I.C. of this preamble.
        If researchers have determined that their R&D activities are 
    subject to TSCA jurisdiction, are intended for commercial purposes, and 
    involve new microorganisms, their R&D activities will be subject to 
    some obligations under TSCA section 5. Researchers would then proceed 
    through the remainder of the questions to determine their reporting 
    status. They would first determine whether their R&D activities are 
    eligible for the contained structures exemption. This determination is 
    discussed below in Unit II.D.2.c.
        The next question deals with other agencies. An R&D activity that 
    is eligible for the contained structures exemption may also be subject 
    to the authority of another Federal agency. Overlapping jurisdiction 
    for R&D conducted in contained structures is discussed below in Unit 
    II.D.2.d.
        If the R&D activity does not qualify for the contained structures 
    exemption, TERA reporting would next need to be considered. However, 
    EPA is also proposing in this rulemaking a category of specific 
    microorganisms that are exempt from TERA reporting. Thus, researchers 
    who are not eligible for the contained structures exemption and/or for 
    deferral to another agency may qualify for a specific TERA exemption. 
    The determination of whether the research qualifies for a TERA 
    exemption is discussed below in Unit II.D.2.e.
        Figure 1 shows the four distinct types of TSCA section 5 
    obligations existing for R&D activities. The reporting requirements for 
    each of these obligations are discussed below in Units II.D.3. and 4. 
    The corresponding paragraphs are noted on the following Figure 1.
    
    TP01SE94.000
    
        2. Specifics for determining eligibility for R&D exemptions. The 
    five points which researchers must consider in order to determine their 
    TSCA section 5 obligations for R&D are discussed in this paragraph.
        a. Determination that the R&D activity is subject to TSCA 
    jurisdiction. Statutory jurisdiction is discussed in Unit I.C. of this 
    preamble. As noted in that Unit, uses of some microorganisms are 
    specifically excluded from TSCA section 5, because they are subject to 
    other statutes. Uses that are not specifically excluded are subject to 
    TSCA. When developing the initial TSCA Inventory, EPA indicated that 
    undifferentiated uses of chemical substances would be subject to TSCA 
    (42 FR 64585, December 23, 1977). In the 1986 Policy Statement, EPA 
    stated that unless the uses were explicitly excluded by TSCA, ``all 
    microorganisms produced for environmental, industrial, or consumer uses 
    are potentially regulable under TSCA'' (51 FR 23324, June 26, 1986). 
    Thus, EPA would consider that R&D activities involving new 
    microorganisms where researchers are unsure of the final use would be 
    subject to TSCA section 5. This would include microorganisms in early 
    stages of research, where the researchers have not determined a 
    specific commercial application of the microorganism. As noted in Unit 
    II.B. of this preamble, researchers who are uncertain of the status of 
    their microorganism, for any reason, should consult EPA regarding their 
    TSCA section 5 obligations.
        b. Determination that the R&D activity is intended for commercial 
    purposes. TSCA section 5 covers only uses of new microorganisms for 
    commercial purposes. EPA discusses its interpretation of commercial R&D 
    in Unit III.A. of this preamble. The Agency is proposing three 
    alternative interpretations of commercial purposes. Depending on public 
    reaction to the alternative interpretations discussed in this proposal, 
    the interpretation of commercial R&D could differ from one R&D activity 
    to another in a final rule, if public comment supports different 
    interpretations for different types of R&D activities.
        c. Determination that the R&D activity is eligible for the 
    contained structures exemption. This exemption would most likely apply 
    to research performed in contained structures such as pilot 
    fermentation plants, greenhouses, laboratories, and certain bioreactors 
    used for waste treatment. The term ``structure'' is defined in proposed 
    Sec. 725.3. Research involving intentional testing of microorganisms in 
    the environment would not be eligible for this exemption. Requirements 
    for the exemption are in section 3 of this Unit. The rationale for this 
    exemption is discussed in Unit III.B. of this preamble.
        d. Determination that oversight of the R&D activity is also subject 
    to the authority of another Federal agency. Some R&D activities may be 
    subject to the authority of another Federal agency in addition to EPA. 
    Where there is overlapping jurisdiction for R&D activities that are 
    eligible for the contained structures exemption, EPA proposes to defer 
    to the other Federal agency which has authority for oversight over such 
    activities. This would apply to researchers who are receiving funding 
    from the other Federal agency, which requires that researchers comply 
    with the ``NIH Guidelines for Research Involving Recombinant DNA 
    Molecules'' (``NIH Guidelines'') in order to receive funding. 
    Researchers who are voluntarily complying with the NIH Guidelines but 
    are not actually receiving funding from a Federal agency would not be 
    eligible for the deferral.
        e. Determination that specific microorganisms are exempt from TERA 
    reporting. EPA is proposing exemptions from TERA reporting for certain 
    new microorganisms derived from the microorganisms Bradyrhizobium 
    japonicum and Rhizobium meliloti. R&D involving these microorganisms 
    performed in accordance with specified conditions would be exempt from 
    review. Additional microorganisms may be exempted by rule under section 
    5(h)(4), as EPA gains familiarity with them. Unit III.C.5. of this 
    preamble discusses the rationale for this exemption.
        3. Requirements necessary for eligibility for exemptions from TERA 
    reporting. Once researchers have determined which exemptions their R&D 
    activities are eligible for, they must determine their specific TSCA 
    section 5 obligations. Proposed Secs. 725.232 through 725.239 specify 
    the requirements for each of the exemptions from TERA reporting.
        a. The contained structures exemption--(i) R&D subject to another 
    Federal agency. R&D activities which are eligible for the contained 
    structures exemption (see Sec. 725.234(a) and (c) of the regulatory 
    text) but are also subject to the oversight of another Federal agency 
    will be exempt from the requirements of TSCA section 5. If researchers 
    comply with the other agency's requirements, there will be no EPA-
    specific requirements (see Sec. 725.232 of the regulatory text).
        (ii) R&D not subject to another Federal agency. This document 
    proposes that R&D eligible for the contained structures exemption but 
    not subject to another Federal agency must be conducted in accordance 
    with proposed Secs. 725.234 (containment and recordkeeping) and 725.235 
    (employee notification). Although researchers that comply with these 
    provisions are not required to report to EPA under TSCA section 5, the 
    recordkeeping and employee notification requirements would apply and 
    would be enforceable by EPA.
        There are two types of standards in Secs. 725.234 and 725.235. The 
    employee notification standards of Sec. 725.235 are taken directly from 
    current regulations in Secs. 720.36 and 721.47, and are the same as 
    those for traditional chemical substances. Section 725.234 contains 
    general research standards but adds some provisions that apply 
    specifically to microorganisms. However, these additional provisions 
    are minor changes to EPA's current requirements for the research 
    exemption, and these provisions should be standard practices for 
    research activities involving microorganisms.
        Specifically, the small quantities exemption for traditional 
    chemical substances requires research to be conducted by, or directly 
    under the supervision of, a technically qualified individual (TQI). 
    This is a requirement under EPA's current regulations at Secs. 720.36 
    and 721.47. Section 725.234 applies the same requirement to 
    microorganisms eligible for the contained structures exemption.
        Section 725.234 states that the TQI must select appropriate 
    measures to control release of the research microorganism, write a 
    brief description of the reasons for choosing the measures and ensure 
    maintenance of records to document routine use of the selected 
    controls. In addition, the choice of control measures must be certified 
    by an authorized official of the institution at which the research is 
    conducted. Finally, EPA may request that the records be sent to EPA for 
    review. Subsequent to such review, EPA may in some circumstances offer 
    recommendations to modify control or documentation measures. In what 
    EPA anticipates would be rare occurrences, EPA might order the 
    researcher to modify controls or documentation measures. Failure to 
    comply with such an order would result in loss of eligibility for the 
    exemption for the specific R&D activity.
        For those researchers who are voluntarily complying with, but are 
    not subject to, the NIH Guidelines, the requirements of the contained 
    structures exemption could be met by having the principal investigators 
    serve as the TQIs (see Sec. 725.234(b) of the regulatory text) and keep 
    records indicating that they abide by the NIH Guidelines.
        b. Exemption from TERA reporting for specific microorganisms. In 
    order to be exempt from both TERA reporting and MCAN reporting, persons 
    using the exemptions for microorganisms listed in Sec. 725.239 must 
    comply with the general requirements for the exemption listed in 
    Sec. 725.238 as well as any specific requirements listed in 
    Sec. 725.239. Similar to its proposal for the tiered exemption for 
    general commercial use discussed in Unit II.C., EPA is proposing to 
    place restrictions on the recipient microorganisms, the introduced 
    genetic material, and the conditions of use (see Sec. 725.239 of the 
    regulatory text).
        4. TERA submission and review process. EPA is proposing to 
    establish the TERA, which is an abbreviated notification process for 
    environmental testing of new microorganisms.
        a. TERA submission process. Sections 725.255 and 725.260 detail 
    specific information that should be submitted with a TERA. The basic 
    microorganism identity information is the same as that for the MCAN. 
    Other information requested specifically addresses the proposed R&D 
    activity and therefore is not as extensive as the MCAN information.
        b. TERA review process. EPA's goal is to review TERAs in 60 days 
    (see Sec. 725.270 of the regulatory text). For good cause, EPA could 
    extend the initial TERA review period by an additional 60 days, for a 
    total of 120 days (see Sec. 725.56 of the regulatory text). Due to the 
    small number of experiments that have been conducted and the 
    uncertainty concerning field tests that involve new microorganisms, EPA 
    expects that initial TERA reviews may take closer to 120 days. During 
    the prenotice consultation, EPA would estimate for the submitter 
    whether the review is likely to require closer to 120 days or 60 days.
        Generally, EPA believes that approval of TERAs in 60 days or less 
    would be possible for field tests that are similar to previously 
    reviewed field tests (for example, use of the same or similar 
    microorganisms, modifications to a previous test, or change in 
    geographic conditions). When novel circumstances are presented in a 
    TERA, however, EPA may need to extend the review period in order to 
    complete its review. Specific examples of extension for good cause 
    would include the need for a subcommittee meeting of the Biotechnology 
    Science Advisory Committee to supplement Agency expertise or the need 
    to coordinate review with other Federal agencies. When EPA coordinates 
    the review of a microorganism with another Federal agency, the review 
    period would automatically be extended to the length of the other 
    agency's review, to allow the two agencies to coordinate reviews and 
    decisionmaking. TERA submitters may not proceed with their field trials 
    until EPA has provided written approval of the TERA submission. As soon 
    as EPA completes its review, however, researchers will be able to start 
    their test immediately upon notification from EPA.
        c. Regulatory decision. EPA will approve a TERA if it determines 
    that the experiment(s) will not present an unreasonable risk to human 
    health or the environment. If the submission is approved, EPA may 
    negotiate with the submitter a TERA Agreement, which would be legally 
    binding on all parties and would set out any conditions governing the 
    conduct of the specific field trial (see Sec. 725.270 of the regulatory 
    text). The TERA Agreement could include provisions for maintaining 
    restrictions on the use of the test site after the completion of the 
    test. This may require the submitter to make appropriate arrangements 
    with the owner of the test site, in cases where the submitter does not 
    own the test site. If EPA concludes that the proposed R&D activity may 
    present an unreasonable risk of injury to human health or the 
    environment, EPA will deny the TERA and will provide reasons for the 
    denial in writing. Section 725.288 provides for revocation or 
    modification of TERA approvals following the receipt of additional 
    information.
        5. Options for oversight of R&D activities--a. Range of options 
    possible. EPA's intent in offering a variety of alternatives for 
    oversight of R&D activities was to provide a flexible process which 
    tailored oversight to the level of risk. In developing TSCA section 5 
    obligations for R&D activities using new microorganisms, EPA looked at 
    a range of options. These fall on a continuum ranging from an option 
    which would exempt all R&D activities under a small quantities 
    exemption similar to the exemption for traditional chemicals to an 
    option which would require TERA reporting for all R&D activities, 
    including those conducted in laboratories and other contained 
    structures.
        As discussed in Unit III.B. of this preamble, because 
    microorganisms can multiply and spread beyond the site of introduction, 
    EPA must redefine the small quantities definition applied to 
    traditional chemicals. EPA developed the TERA process, because it 
    believes that review of environmental uses of microorganisms should 
    begin during the R&D stage. At the same time, EPA does not believe that 
    all microorganisms used in all R&D activities should be subject to TERA 
    reporting. Neither of the extreme options seemed appropriate to EPA for 
    coverage of R&D, because they would not be tailored to potential risk. 
    Thus, EPA chose an intermediate approach.
        In keeping with the goals of the Coordinated Framework, EPA has 
    included in its proposed option opportunities to address overlapping 
    jurisdiction with other Federal agencies. EPA has attempted to balance 
    the Coordinated Framework's goal to reduce duplicative oversight with 
    TSCA section 5's goal to screen for potential unreasonable risks. As 
    discussed in Unit III.B. of this preamble, in developing its 
    requirements for the contained structures exemption, EPA selected an 
    approach which recognized the diversity of microorganisms which would 
    be used in research and therefore left to the researcher the choice of 
    appropriate containment and inactivation controls. Additionally, in 
    order to keep the TERA process flexible, EPA has developed a provision 
    allowing microorganisms tested in the environment to be exempted from 
    TERA reporting as the Agency gains more familiarity with them.
        EPA requests comments on its proposed option for R&D activities for 
    TSCA microorganisms. In particular, EPA would like to know whether 
    commenters feel that the flexibility provided by the various exemptions 
    available under the proposed option counterbalances the complexity of 
    the approach. The public may suggest other options along the continuum, 
    providing those options also meet the intent of TSCA and adequately 
    protect public health and the environment from unreasonable risks. In 
    addition to the proposed option, when EPA prepares its final rule, it 
    will consider the variety of options along the continuum discussed 
    above, as well as options suggested by the public.
        b. Specific alternative for low risk field tests. EPA realizes that 
    there are a variety of possible options along the continuum discussed 
    above. Although EPA has decided that case-by-case review is important 
    for many microorganisms intentionally tested in the environment, EPA 
    recognizes that there will be low risk field tests that would not 
    require TERA review. For this reason, some have suggested an 
    alternative exemption for certain R&D releases. This alternative, which 
    is similar to the R&D contained structures exemption in that it would 
    be dependent on determinations made by a TQI, would apply to certain 
    low risk field tests and would be included with the exemptions which 
    are part of the proposal for coverage of R&D activities under TSCA 
    section 5. Like the proposed exemption for R&D in contained structures, 
    this alternative would contain requirements for documentation and 
    recordkeeping by a TQI and certification by an authorized company 
    official. It would also provide for EPA to inspect records and order 
    changes, if necessary.
        Under this alternative, a company planning a small-scale field test 
    which meets the eligibility requirements for the exemption would have 
    the option of submitting a TERA for review by EPA or submitting a 
    notice with the determination that the field test qualified for the 
    exemption. The alternative includes a number of requirements which are 
    intended to minimize the likelihood of inconsistent determinations.
        The TQI would be expected to make the determination that the new 
    microorganism was eligible for the exemption, based on the following: 
    (1) The test site must be 10 acres or less of land, (2) the parent 
    microorganism(s) must have a history of safe use, and (3) the 
    introduced genetic material must be limited in size, well-
    characterized, free of certain nucleotide sequences, and poorly 
    mobilizable. Further explanation of the terms in (3) appears in Unit 
    III.C.7. of this preamble.
        In determining that the parent microorganism has a history of safe 
    use, EPA would expect researchers to be able to classify taxonomically 
    the microorganism and to evaluate its relationship with closely related 
    microorganisms which may have a potential for adverse effects on human 
    health or the environment. Information on the potential for the 
    microorganism to cause adverse effects on human health and the 
    environment should be evaluated.
        EPA recognizes that a determination that a microorganism has a 
    history of safe use involves a balancing of various factors. This 
    determination should be premised on the researcher's prediction of the 
    behavior of the microorganism based on experience with its use. The 
    more information the researcher has on the behavior of the 
    microorganism (for example, the ability to establish, compete, and 
    survive in the environment), the better the researcher can estimate the 
    safety of the field test. In conducting their risk assessment, 
    researchers should consider the scale, since the tests must be 
    conducted on 10 acres or less of land.
        An additional requirement for this alternative exemption would be 
    that an official having authority to represent the organization (e.g., 
    the Chief Executive Officer, the General Counsel) certifies that the 
    determination has been made by a TQI and is considered to be the 
    official position of the organization. The official would also be 
    required to state that the organization accepts full liability for all 
    potentially harmful consequences of the field test. To show that 
    relevant considerations had been evaluated, a TQI would be required to 
    prepare a written analysis to be kept in the company's records. These 
    records would be kept for 5 years from the date of the field test, with 
    EPA retaining the right to review the records upon request. In lieu of 
    a TQI, the analysis could be performed by a third party review group 
    with relevant scientific expertise (i.e., ecological expertise) as 
    exemplified by the Institutional Biosafety Committees (IBCs) described 
    in the NIH Guidelines.
        Following the TQI's determination, the researcher would be required 
    to submit a short notice to EPA, providing the organization name and 
    address, a summary of the new microorganism and the proposed field 
    test, the name of the TQI, and the official certification, including 
    the liability statement. EPA would have 45 days to determine whether to 
    require submission of a TERA before the researcher could conduct the 
    planned field test.
        EPA requests comments on this alternative approach for low risk 
    field tests. In particular, EPA would like to know whether there are 
    other criteria which would be appropriate for defining a category of 
    low risk small-scale field tests and what additional guidance would be 
    needed for researchers to utilize such an approach. The rationale for 
    this alternative exemption is discussed in Unit III.C. of this 
    preamble.
    
    III. Rationale for Proposed Reporting Mechanisms
    
    A. Research for Commercial Purposes
    
        1. Introduction. TSCA section 5(i), while it limits all section 5 
    screening to activities for commercial purposes, has had little 
    practical effect on research using traditional chemicals, because of 
    the research exemption. However, because this proposed rule would place 
    more requirements on research with microorganisms than on research with 
    traditional chemicals, EPA believes it should provide its current view 
    on the applicability of the commercial purposes limitation to this 
    proposed rule.
        As a preliminary matter, there is no difficulty in determining when 
    any chemical substance, including a microorganism, is being 
    manufactured or processed for a commercial purpose after the R&D stage. 
    It is clear when a PMN is required or when a MCAN would be required at 
    general commercial use.
        Research on traditional chemicals is not generally affected by the 
    commercial purposes limitation, because EPA's current regulatory 
    definition of small quantities for R&D using traditional chemicals (any 
    amounts reasonably necessary for research) at Sec. 720.3 effectively 
    exempts research with these chemicals from section 5 screening. 
    However, as noted in Unit III.B. of this preamble, these rules propose 
    a small quantities definition for microorganisms; and this definition, 
    because it would recognize the ability of microorganisms to reproduce, 
    would differ from the definition for traditional chemicals. A 
    researcher utilizing microorganisms, therefore, may need to consider 
    what constitutes a commercial purpose.
        Research involving microorganisms used in contained structures 
    would be considered ``small quantities solely for research and 
    development'' as defined at Sec. 725.3 of the regulatory text. Although 
    EPA expects the requirements for this contained structures exemption 
    simply to reflect common practices, a researcher may have to evaluate 
    whether research conducted in contained structures is commercial. The 
    contained structures exemption would not apply to field testing of 
    microorganisms because of the ability of living microorganisms to 
    reproduce and spread in the environment (see Unit III.B. of this 
    preamble). As a result researchers will, in all cases, need to decide 
    which environmental testing is commercial.
        EPA wishes to emphasize that any coverage of research under this 
    proposed rule should not duplicate appropriate oversight by other 
    Federal authorities. As explained in Unit III.C.3. of this preamble, 
    contained research appropriately overseen by other Federal agencies 
    would be exempt from EPA oversight, because EPA believes such research 
    does not present an unreasonable risk. As a practical matter, 
    therefore, while testing conducted at institutions that do not normally 
    consider themselves commercial (academic and non-profit institutions) 
    could theoretically be commercial under interpretations discussed in 
    this Unit, EPA anticipates that other parts of these rules will exempt 
    much of the research from EPA oversight.
        2. Public comments. During development of regulations on 
    biotechnology, EPA has received numerous public comments that differ 
    substantially on oversight of research. Of particular concern has been 
    the appropriateness of EPA review based on the status of an activity as 
    commercial rather than on its potential risk.
        Comments argue that there is no reason to suspect any difference in 
    risk between commercial or noncommercial research. Thus, if a 
    university and a business release the same microorganism in similar 
    settings, both should be subject to oversight.
        On the other hand, comments suggest there may be risk differences. 
    Some argue that a commercial enterprise is more likely to be careful 
    than a noncommercial institution due to concern for liability. Others 
    argue that academic researchers are more likely to be concerned with, 
    and aware of, the need to consider health and environmental safety 
    issues and that commercial entities may be willing to take shortcuts in 
    the interest of reducing costs.
        Other comments complain that increased government regulations may 
    have a deleterious effect on academic research, because it may be more 
    difficult for pure research institutions to comply. Burdens that are 
    relatively minor for a business could be major for a university or an 
    individual researcher.
        Comments have also indicated that a number of practical 
    difficulties increase the burden on research institutions. For example, 
    increasingly complex and intermingled financial arrangements in the 
    biotechnology field have emerged as universities seek funding from 
    businesses. These arrangements may result in universities conducting 
    product development for money or equipment donations from business. 
    Undue burdens to academic researchers can result from requirements that 
    research which is funded by a commercial entity be distinguished from 
    that funded by a noncommercial entity, particularly when a university 
    may pool its funds from various sources.
        Finally, even though an academic research institution may engage in 
    product development for a business, the institution may not be engaging 
    in a commercial activity for its own benefit. For example, a university 
    may use income from a commercial entity to improve its teaching and its 
    ability to increase knowledge. Industry could be an important source of 
    income for upgrading equipment used for teaching.
        The remainder of this Unit discusses EPA's view of the law and 
    policy and responds to these public comments.
        3. EPA's view of the law as it applies to commercial activities at 
    noncommercial institutions. EPA wishes to make it clear that the 
    interpretations discussed in this Unit are consistent with 
    interpretations in current regulations. That is, a commercial activity 
    is one undertaken with the purpose of obtaining an immediate or 
    eventual commercial advantage. This is the common thread in 
    Sec. 720.3(r) which defines ``manufacture or import for commercial 
    purposes'' and Sec. 721.3 which defines ``process for commercial 
    purposes.'' Similarly, Sec. 720.30(i) provides that ``non-commercial 
    research and development'' consists of activities conducted by 
    academic, government, or independent not-for-profit organizations 
    ``unless the activity is for eventual commercial purposes.''
        All research conducted directly by a commercial entity is clearly 
    for commercial purposes, as was decided in The Dow Chemical Company v. 
    EPA, 605 F.2d 673 (3d Cir. 1979). Consequently, if a business directly 
    funds a research activity for product development, the activity is for 
    commercial purposes, regardless of the location. A business may not 
    avoid review by simply funding research at an academic institution.
        In section 5, Congress distinguished between commercial and 
    noncommercial activities and, thus, expected them to be treated 
    differently. Although the statute has no definitive explanation as to 
    what this distinction means, it does not appear to have been risk-
    based. EPA believes that Congress did not provide a definitive 
    explanation and therefore left to the Agency's discretion the balancing 
    of competing interests. TSCA section 2(b) states that it is the policy 
    of the United States that TSCA authority should be exercised so as not 
    to ``impede unduly or create unnecessary economic barriers to 
    technological innovation,'' while fulfilling the primary purpose of 
    assuring that innovation does not present unreasonable risks.
        If EPA considers that section 5 provides a screening mechanism, as 
    opposed to a direct regulatory mechanism, EPA has an indication why the 
    commercial purposes limitation applies. Under other TSCA provisions, 
    EPA may regulate without regard to a commercial purposes limitation. 
    For example, the commercial purposes limitation does not apply to EPA's 
    authority under TSCA section 6 to prohibit or limit manufacture, 
    processing, or distribution in commerce of chemical substances if the 
    Agency finds that the particular activities present an unreasonable 
    risk.
        By providing a commercial purposes limitation for EPA to cover 
    early phases of product development, Congress recognized the need for 
    EPA to balance the competing interests of fostering innovation and 
    protecting human health and the environment from unreasonable risk. In 
    balancing these interests, EPA could construe the commercial purposes 
    limitation to exclude relatively few activities during screening to 
    cover a broad range of risk possibilities. Therefore, the broadest 
    meaning of commercial purposes would miss hardly any research.
        4. Alternative interpretations affecting which activities at 
    noncommercial institutions will be considered commercial. Any of the 
    three alternative interpretations of commercial purposes set forth 
    below, as well as any other interpretation that is suggested by public 
    comment and meets the intent of TSCA and adequately protects public 
    health and the environment from unreasonable risks, may be adopted by 
    the Agency in its final rule. Regardless of the alternative chosen, EPA 
    would encourage researchers to voluntarily consult with EPA to find out 
    if EPA considers their research to be commercial.
        a. Indicia of commercial purposes. The usual way to interpret a 
    statutory term of art like ``commercial purposes'' would be to look for 
    indicia of commercial intent. This is what EPA does in its TSCA section 
    5 program for traditional chemicals. The Agency has not provided any 
    detailed public discussion of what these indicia may be for traditional 
    chemicals, but because the Agency will be reviewing R&D activities in 
    its biotechnology program, a discussion of these indicia for the 
    biotechnology program is appropriate.
        While EPA may develop a general discussion, no exhaustive list of 
    commercial indicia can be developed a priori. If EPA adopts this 
    approach, the commercial indicia would apply to R&D in laboratories and 
    other contained structures, as well as to intentional testing in the 
    environment. Some environmental testing of new microorganisms would not 
    be screened, because it would not be for commercial purposes.
        EPA acknowledges that noncommercial institutions may find it 
    difficult to trace funding for particular activities or to decide 
    whether an activity is commercial or not. However, EPA supports this 
    alternative, under the theory that the burdens of reporting to EPA are 
    costs of doing business for any organization that wants the benefits of 
    commercial financing. In addition, EPA believes that reporting at the 
    research stage under this proposed rule does not impose an unnecessary 
    burden on innovation and that the indicia described below would be 
    consistent with the intent of TSCA. There are two general categories of 
    commercial indicia for activities at nonprofit institutions; one 
    involves industry involvement, either directly or indirectly; the other 
    does not.
        (i) Direct industry involvement. As noted above, any direct 
    industry involvement in an activity at a noncommercial institution is 
    for commercial purposes. Examples of direct commercial funding include 
    situations in which a commercial entity contracts directly with a 
    university, or gives a conditional grant where the commercial entity 
    holds patent rights, or establishes a joint venture where the 
    commercial entity holds patent or licensing rights.
        (ii) Indirect industry involvement. Indirect benefits to the 
    commercial entity are not as clear. For example, a commercial entity 
    may give a gift to a research institution with no limits on the use of 
    the funds or research results. However, since the funds originated from 
    a commercial source, a commercial purpose may nonetheless exist. Other 
    indirect relationships between commercial and noncommercial entities 
    need to be considered. For example, a commercial entity may guarantee a 
    university bank loan for research, a faculty member associated with 
    biotechnology research may have a financial interest in a biotechnology 
    company, research may be conducted at a science park jointly owned by a 
    university and commercial enterprises.
        (iii) No industry involvement. If there is no industry involvement, 
    EPA needs to look at the intent of the individual researcher or 
    institution. Entrepreneurial faculty members may obtain financial 
    rewards from their own inventions. Some may take out personal patents 
    or derive personal income. The university may benefit from the patents 
    or may sell products or services commercially, for example, to farmers. 
    Because products may be sold to consumers, EPA is inclined to consider 
    these activities commercial. However, if profits are used to support 
    research or improve teaching facilities, EPA may recognize a case for 
    considering the activity not to be commercial.
        EPA could also consider activities supported by Federal or State 
    government to be commercial. Many of these government activities are 
    designed to foster economic benefits for particular groups, such as 
    farmers. Also, the government may support university centers for 
    technology transfer to industry. The issue may be philosophical, 
    regarding whether government economic activities benefit individuals or 
    the general welfare. EPA believes there are legitimate arguments for 
    either view.
        Finally, EPA may consider all activities at a nonprofit institution 
    to be commercial if any activity is. Thus, if a company finances one 
    activity at the university, all of the university's research may be 
    considered commercial. If a university has an equity interest in a 
    biotechnology company or a faculty member is associated with a firm, 
    all the university's research activities may be considered commercial. 
    This interpretation is supported by the fact that commercial activities 
    free resources for noncommercial activities.
        If EPA interprets all these situations strictly, for practical 
    purposes, almost all research could be commercial. EPA notes for 
    comment, however, not-for-profit institutions that obtain self-
    generated funds through charitable or religious donations and 
    government grants for pure research to identify health or environmental 
    hazards. These situations may not be commercial under any 
    circumstances.
        Regardless of the alternative chosen for environmental research, 
    EPA would base its interpretation of commercial purposes for research 
    qualifying for the contained structures exemption on the broad set of 
    indicia discussed under this first alternative, in light of its belief 
    that EPA requirements for contained commercial R&D are similar to 
    requirements placed on academic researchers by the NIH Guidelines. See 
    Unit III.B. of this preamble. Therefore, the second and third 
    alternatives would apply only to research which does not qualify for 
    the contained structures exemption.
        b. All environmental research is commercial. Because of the ability 
    of microorganisms to reproduce, disseminate and spread and the features 
    of intentional testing in the environment, EPA believes it should 
    propose another interpretation to address such testing. Under this 
    interpretation, all intentional testing outside of contained structures 
    would be commercial. This interpretation would avoid the most 
    significant problem identified by comments, which is that there is no 
    real difference in risk between research conducted by industry and by 
    noncommercial entities.
        As discussed more fully in Unit III.B. of this preamble, 
    microorganisms function differently than other chemical substances. 
    Because R&D involving the introduction of new microorganisms into the 
    environment involves greater uncertainty than R&D involving use of 
    microorganisms under contained conditions, EPA believes that a 
    different position is warranted for intentional testing of 
    microorganisms in the environment.
        Because the TERA burden is structured to be minimal, EPA believes 
    reporting will not seriously restrict academic R&D. In fact, this 
    interpretation of commercial purposes in some respects could lessen the 
    burden on universities, because they will not have to separate their 
    industry funding from other funding that they may not consider 
    commercial.
        While considering all environmental releases to be commercial may 
    seem contrary to the usual view, the actual status of funding for the 
    biotechnology industry supports this interpretation. Research 
    relationships in biotechnology are pervasive and take many forms. 
    According to an Office of Technology Assessment (OTA) report,
    
        in recent years, the rapid proliferation of collaborations in 
    biological research, involving partnerships between universities, 
    industry and government, has greatly extended the frequency, scope 
    and visibility of such activities. Attempts to commercialize 
    biological techniques have occurred at an accelerated rate when 
    compared to other fields, involving a greater range of commercial 
    application than discoveries in most other disciplines. (Ref. 4, 
    page 13).
    
        Even the United States government is involved, under the Technology 
    Transfer Act, in the commercialization of biotechnology, having 
    developed a technology transfer policy between universities and 
    industry with the goal of developing commercially useful products. 
    Nonprofit foundations also participate in activities for commercial 
    purposes, often to finance other nonprofit activities.
        c. Rebuttable presumption of commercial activity. The same 
    arguments for the option that all environmental releases are commercial 
    support the rebuttable presumption option. The rebuttable presumption 
    is also supported by the need to distinguish commercial and 
    noncommercial activities under TSCA. The above discussion of commercial 
    indicia indicates the types of evidence that a researcher may present 
    to rebut the presumption. However, EPA believes that this option would 
    be burdensome to researchers, because it would require them to maintain 
    evidence concerning sources of funding for each environmental 
    experiment. EPA also believes that this approach would be less 
    protective of public health and the environment, because it does not 
    adequately address uncertainty about the behavior of new microorganisms 
    in the environment.
        d. Voluntary consultation. EPA recognizes that regardless of the 
    interpretation of commercial purposes adopted for the final rule, it 
    will be difficult to apply any one interpretation in all cases. For 
    this reason, EPA would encourage persons who believe that they are 
    engaging in non-commercial R&D to voluntarily consult the Agency before 
    initiating testing of microorganisms that would be considered new if 
    used for commercial purposes.
    
    B. Exemption for Research in Contained Structures
    
        This Unit explains EPA's reasons for exempting from section 5 
    screening R&D activities performed under conditions that would minimize 
    the number of microorganisms emitted, or where appropriate prevent 
    emission of microorganisms from structures such as pilot fermentation 
    facilities, greenhouses, and laboratories. The R&D reporting process is 
    discussed in Unit II.D. of this preamble.
        1. Background. The statutory authority for this exemption is TSCA 
    section 5(h)(3). Section 5(h)(3) exempts from section 5 screening 
    chemical substances manufactured or processed in small quantities 
    solely for R&D, and directs EPA to define small quantities by rule. 
    Accordingly, proposed Sec. 725.3 provides that R&D activities involving 
    microorganisms would qualify for the section 5(h)(3) exemption when 
    these activities are conducted under conditions designed to meet 
    appropriate standards of containment and when employees are notified of 
    risks. Some R&D activities which are eligible for the contained 
    structures exemption may also be subject to the jurisdiction of another 
    Federal agency. In these cases, EPA proposes to defer to the authority 
    of the other Agency. The rationale for this proposed deferral is 
    discussed in Unit III.C.3. of this preamble.
        2. Difficulties in ensuring that microorganisms used for R&D will 
    not increase beyond small quantities. EPA's current regulations for 
    traditional chemicals at Sec. 720.3(cc) define ``small quantities 
    solely for R&D'' as those quantities that are ``not greater than 
    reasonably necessary for ... [R&D] purposes.'' This definition of small 
    quantities for R&D has been appropriate for traditional chemical 
    substances, because these chemicals do not have the ability to increase 
    their own volume or amount. To the extent a finite amount of a 
    traditional chemical released during an experiment may leave a test 
    site, it will only be diluted in the environment.
        Living microorganisms are not, however, subject to these same 
    limitations. Microorganisms may reproduce and increase beyond the 
    number initially introduced, may establish in the environment (i.e., 
    develop a self-sustaining population), and may spread beyond the test 
    site. Thus, what begins as a small, localized population of 
    microorganisms may become a large, widespread population. Even if 
    certain microorganisms do not exhibit the ability to reproduce, 
    increase in number, establish, and spread beyond the test site, they 
    may be capable of passing some of their traits to other microorganisms 
    in the environment. These other microorganisms may, in turn, multiply, 
    establish, spread and subsequently pass the acquired trait to other 
    microorganisms. This could result in widespread propagation of the 
    trait, and exposure of a number of different environments to novel 
    traits.
        These abilities of living microorganisms render the general 
    definition of small quantities that applies well to traditional 
    chemicals invalid for microorganisms. If the definition developed for 
    traditional chemicals was applied to living microorganisms, EPA would 
    not review microorganisms until they were produced for general 
    commercial use. New microorganisms could be released, with no EPA 
    review, during R&D testing in the environment, perhaps numerous times, 
    and could become established and spread. This would defeat the purpose 
    of TSCA, which is designed to permit EPA to review chemical substances 
    before they become widely disseminated.
        Consequently, a determination of what constitutes small quantities 
    for microorganisms requires that more factors be taken into 
    consideration than are considered for traditional chemicals. These 
    factors revolve around the probability that a microorganism will 
    establish itself in the environment. Establishment is a key 
    consideration, because unless a microorganism establishes, any effects 
    it might have would probably be spatially and temporally limited. 
    Several factors influence whether a microorganism will be able to 
    establish itself. These include the numbers of microorganisms involved, 
    the frequency with which they are applied to the area, the method of 
    application, the characteristics of the microorganism, the 
    physiological condition of the microorganism at the time of 
    application, and the characteristics and condition of the receiving 
    environment.
        Case histories of both disease epidemics and invasions of higher 
    organisms suggest that the number of organisms present in the inoculum 
    directly influences whether the introduction yields a self-sustaining 
    population (Ref. 5). Experience with microorganisms used in biocontrol 
    (i.e., purposeful use of microorganisms as antagonists to reduce the 
    disease-producing ability of plant pathogens) has shown that success in 
    some instances can be enhanced if a large number of the biocontrol 
    microorganism is introduced (Ref. 6).
        It can be inferred from this information that the number of 
    organisms, both with regard to the density of the inoculum and the 
    geographic range over which it is introduced (Refs. 7 and 8), is 
    related to probability of establishment. Several hypotheses on why this 
    may be so can be offered. In some cases, mortality in the introduced 
    population can be overcome if the inoculum contains a large number of 
    individuals. In other situations, a large inoculum population may 
    provide sufficient genetic variation that individuals that can tolerate 
    or prosper in the environment of introduction will be within the 
    inoculum (Refs. 9 and 10). A biocontrol strategy that relies on the 
    inoculum containing large numbers of microorganisms is thought to be 
    successful because the introduced microorganisms may by sheer numbers 
    have an advantage in reaching and filling available suitable 
    microhabitats, availability of suitable habitat being a limiting factor 
    for any population of organisms.
        The frequency with which organisms are released to an environment 
    also affects whether an organism can establish. Frequent releases 
    increase the likelihood that the microorganism will find sites 
    favorable for establishment by increasing the total number of 
    microorganisms placed in the environment and by increasing the 
    probability that a microorganism will be introduced during a time 
    favorable for establishment. This latter probability is related to 
    factors such as the variations in temperature, moisture, light, and 
    biota observed with seasonality. In other words, conditions favorable 
    for establishment may exist at some period of time and not at others, 
    and frequent application increases the probability that some 
    individuals will be at the right place at the right time.
        3. Regulatory conditions to prevent microorganisms used for R&D 
    from increasing beyond small quantities. EPA's proposed standards at 
    Secs. 725.234 (containment and recordkeeping) and 725.235 (employee 
    notification) are designed to reduce the probability of establishment 
    by reducing the number and frequency of viable microorganisms emitted 
    from a facility. The reduced probability of establishment increases the 
    probability that a microorganism will remain a small quantity.
        EPA is proposing performance-based standards for this exemption. 
    EPA's approach relies on the experience and judgement of the TQI, and 
    EPA will not generally substitute its own judgement for that of the 
    TQI. The approach recognizes that many different kinds of 
    microorganisms displaying a wide range of characteristics could 
    potentially be used in research, and that for certain microorganisms, 
    emission of only a few viable individuals could cause an effect, while 
    emission of large quantities of viable microorganisms of another type 
    would not. It also recognizes that the type of controls (e.g., 
    procedural, mechanical, and/or engineering) appropriate for one 
    microorganism might have limited relevance to other microorganisms. EPA 
    expects that the TQI will be cognizant of these factors when selecting 
    containment and inactivation controls appropriate to the 
    microorganism(s) being utilized.
        EPA does not believe the documentation requirements proposed for 
    this exemption will be overly burdensome. EPA believes that for most 
    cases, laboratory notebooks normally kept in the course of research 
    will contain most of the information required by this proposal. Control 
    measures selected could be indicated by reference to existing standards 
    (e.g., one of the containment levels described in the NIH Guidelines). 
    The TQI would simply record the reasons for choosing particular 
    measures. With regard to the requirement that records document use of 
    the selected controls, EPA is relying on the TQI to prepare and retain 
    the appropriate degree of documentation. The amount of documentation 
    would be correlated with the characteristics of the research 
    microorganism and standard practices employed to address risk. Thus, 
    documentation could range from general documentation of routine 
    standard operating procedures, to specific notations in laboratory 
    notebooks, to daily log entries for microorganisms that present the 
    greatest risk concerns. If the NIH Guidelines are used as guidance, the 
    TQI's notebook should indicate the level of containment recommended by 
    the Guidelines and that this guidance was selected and used. EPA 
    believes that persons following the NIH Guidelines would keep adequate 
    records as part of normal procedures for informing their Institutional 
    Biosafety Committee of the contained research.
        With respect to the certification requirement, many if not most 
    research institutions have Institutional Biosafety Committees (IBCs) as 
    required by the NIH Guidelines, or committees fulfilling a similar 
    role. These committees are charged with assessing the containment 
    selected by the investigator. EPA recognizes the value of this NIH 
    system and would like to make its requirements consistent to the extent 
    possible with such existing systems. The Agency also encourages the 
    active use of such committees.
        The provision which indicates that EPA may request these records be 
    sent to EPA for review (see Sec. 725.234(d)(3) of the regulatory text) 
    is a restatement of the authority EPA has under TSCA section 11 to 
    request and review information. It is also similar to provisions used 
    by EPA in other exemptions. In the three exemptions from PMN reporting 
    under part 723 that currently exist for traditional chemicals, one of 
    the conditions for eligibility for the exemptions gives EPA access to 
    the records demonstrating eligibility for the exemptions. EPA can 
    require a company to produce the records upon EPA's written request.
        EPA does not plan to routinely review such records, although it may 
    choose periodically to select some records for review. Should the 
    institution or researcher receive a request for records review, the 
    status of the research as exempt would not a priori be affected. 
    Technical staff with experience reviewing TERA and MCAN submissions 
    would examine the records. This provision allows EPA and the researcher 
    to discuss what constitutes appropriate control measures and 
    appropriate implementation and use. Under this provision, EPA may, upon 
    review of the records, offer recommendations concerning what it 
    considers appropriate control measures for the specific microorganisms 
    used in the research. These recommendations would be non-binding. If 
    EPA determines, however, that the control measures selected and used 
    are so inadequate as to present an unreasonable risk, EPA can issue an 
    order directed at modifying the control measures it finds problematic. 
    Refusal to comply with an order would result in loss of eligibility for 
    the exemption for the research in question. The researcher would then 
    be subject to the notification requirements of TSCA section 5.
        EPA's criteria at proposed Secs. 725.234 and 725.235 are designed 
    to reduce the probability of establishment by reducing the number of 
    viable microorganisms emitted from a facility. However, EPA's proposed 
    approach also takes into consideration factors such as the 
    physiological condition of the microorganisms and how this might affect 
    the ability of microorganisms to establish in the environment. 
    Microorganisms used in laboratory research are more likely to be 
    debilitated with regard to their ability to compete in the environment 
    against wild type relatives. Thus, they may be less likely to prevail 
    in the struggle in nature for limited resources. In general, incidental 
    releases of microorganisms from research facilities are less likely to 
    occur under conditions which favor the establishment of the 
    microorganism. Incidentally released microorganisms may be 
    physiologically debilitated by aerosolization or other process 
    procedures, and may be less likely to find an environment that favors 
    their survival and persistence than those microorganisms that are 
    specifically tested in an environment where they are intended to 
    survive, at least long enough to perform a specific function.
        EPA recognizes that parts of the rationale offered for exempting 
    research conducted under the conditions set forth in proposed 
    Sec. 725.234 can be applied to some small-scale field tests involving 
    microorganisms. The rationale cannot, however, be applied to small 
    scale field tests as a class. Microorganisms intentionally tested in 
    the environment are more likely to be acclimated to the environment 
    into which they are introduced, be physiologically fit enough to be 
    competitive in that environment for a significant period of time, and 
    be placed in an area suitable for growth and persistence. Because of 
    the lessons learned with biocontrol microorganisms, researchers will 
    purposefully apply large enough numbers to ensure that the 
    microorganism persists long enough and competes well enough to perform 
    the function the researcher intends to study. In general, the 
    probability that these types of microorganisms, used under these 
    conditions, will establish is thus higher than the probability 
    associated with incidental emissions from facilities employing EPA's 
    proposed criteria.
        4. Alternative reasons for the research exemption. An alternative 
    rationale would hold that the small quantities exemption in section 
    5(h)(3) does not apply to microorganisms as a class, because some 
    microorganisms, whether they are released through intentional testing 
    or incidental emission, can establish even though the initial inoculum 
    is very small. For some microorganisms, a single microorganism may be a 
    sufficient inoculum for establishment to occur. Thus, for 
    microorganisms as a class, there can be no concept of ``small 
    quantities'' similar to that envisioned for other chemicals.
        EPA would find, however, that research conducted under the criteria 
    specified in Secs. 725.234 and 725.235 could be exempted under TSCA 
    section 5(h)(4). EPA's authority under TSCA Sec. 5(h)(4) is discussed 
    in Unit III.C. of this preamble. In situations where the EPA criteria 
    at Secs. 725.234 and 725.235 are followed, EPA believes that the 
    resulting reduction in the number of microorganisms emitted from R&D 
    facilities will reduce the probability that a microorganism will 
    establish in the environment. This reduced probability of establishment 
    leads directly to a reduction in risk. If a microorganism does not 
    establish, its ability to present risk is far less likely to be 
    expressed. If the microorganism is not able to establish, any adverse 
    effects that might be associated with that microorganism will probably 
    be spatially and temporally limited.
        EPA recognizes that some research activities may present special 
    considerations; e.g., when the research utilizes microorganisms that 
    can successfully establish from a very small inoculum. In such cases, 
    incidental emission from the facility may have to be much more 
    stringently controlled to reduce risk. EPA believes that its 
    requirement that a technically qualified individual (TQI) select and 
    validate procedures appropriate to the microorganism addresses this 
    concern. That person should select, validate, and follow procedures 
    that would ensure that insufficient numbers of viable microorganisms 
    are emitted from the facility for establishment to occur.
        EPA believes that any potential risk presented by incidental 
    releases from research facilities that might occur, even when its 
    criteria for reducing the number of microorganisms emitted from the 
    facility are followed, is outweighed by the benefits to society of 
    biotechnology research. EPA can use its limited resources, which 
    otherwise would be used to review these low risk research activities 
    for microorganisms, for reviewing higher risk activities and 
    microorganisms. Industry, by having this exemption, can develop and 
    test microorganisms in the early stages of the product development 
    process (e.g., laboratory) without having to be reviewed by EPA. This 
    would reduce the time and cost for industry in developing new products. 
    More time and resources could be allotted for actual R&D and less time 
    and resources allotted to EPA notifications. This should assist the 
    development of this industry and the emergence of new, useful products, 
    and thus not present an unreasonable risk of injury to human health and 
    the environment.
        5. Alternative methods of reducing the number of microorganisms 
    emitted. EPA believes its proposed approach to reducing the number of 
    microorganisms emitted from research facilities is preferable to more 
    prescriptive approaches which have been suggested. The suggested 
    approaches include setting a specific numerical standard for the number 
    of microorganisms that might be incidentally released to the 
    environment from a research facility, prescribing a single standard 
    based on one of the containment levels described in the NIH Guidelines, 
    or an approach wherein several increasingly stringent levels of 
    containment are described and specific microorganisms are matched to 
    specific levels. These three approaches would be complex and unwieldy 
    to implement. Because of their prescriptive nature, such approaches 
    would result in EPA regulating the containment standards rather than 
    exempting the research. This would unnecessarily restrict research 
    contrary to the intent of TSCA. Each change to a prescriptive standard 
    would have to be incorporated into the standards through rule 
    amendments or variance procedures. Establishing prescriptive standards 
    could restrict advances in technology for controlling microorganisms 
    and stifle individual initiative at the research level.
    
    C. Section 5(h)(4) Exemptions
    
        1. Introduction--a. Statutory background. Section 5(h)(4) of TSCA 
    provides that EPA may exempt by rule the manufacture of any new 
    chemical substance from all or part of the requirements of section 5, 
    if it is determined that activities involving the substance will not 
    present an unreasonable risk of injury to health or the environment. A 
    section 5(h)(4) rule must be promulgated under the procedures set forth 
    in TSCA sections 6(c)(2) and (3), which generally require preparation 
    of a rulemaking record and an administrative hearing. EPA is proposing 
    to use section 5(h)(4) to support various exemptions from the 
    notification requirements of the rule.
        The term ``unreasonable risk'' is not defined in TSCA. Section 6(c) 
    of TSCA lists considerations for determining whether a chemical 
    substance presents an unreasonable risk for purposes of promulgating 
    regulations under TSCA section 6. These considerations include the 
    effects of the substance on human health and on the environment and the 
    magnitude of exposure to the substance, the benefits of the substance 
    for various uses, the availability of substitutes for such uses, and 
    the reasonably ascertainable economic consequences of the potential 
    regulatory action, considering effects on the national economy, small 
    business, technological innovation, the environment, and public health. 
    EPA believes it is reasonable to consider these factors in determining 
    whether a risk is unreasonable under section 5(h)(4).
        TSCA offers no further direct guidance on what constitutes 
    unreasonable risk. In particular, TSCA does not discuss how each of the 
    section 6(c) considerations are to be weighed in relation to each 
    other. The legislative history, therefore, needs to be considered. The 
    House Report (H.R. Rep. 94-1341, 94th Cong., 2d Sess. at 13-15, 32) 
    provides the most useful pertinent explanation. First, the standard 
    under TSCA is ``unreasonable'' risk, not a decision to eliminate all 
    risk (House Report at 15). For an activity that is of some value to 
    society, some level of risk may be acceptable. With respect to section 
    5(h)(4), granting an exemption does not require a showing that there 
    will be no risk, only that there will be no unreasonable risk.
        The House Report states that the unreasonable risk standard cannot 
    be defined in precise terms but, instead, requires exercise of judgment 
    by the decisionmaker. The House Report describes the finding of 
    unreasonable risk as involving a balancing of the probability that harm 
    will occur, and the magnitude and severity (potential consequences) of 
    that harm, against the effects (social and economic) of proposed action 
    on society.
        According to the House Report, these evaluations of harm often must 
    be based on considerations of ``scientific theories, projections of 
    trends from currently available data, modeling using reasonable 
    assumptions, and extrapolations from limited data'' (House Report at 
    32). The unreasonable risk standard recognizes that, as a practical 
    matter, all the scientific evidence is uncertain to some degree and 
    that EPA can consider such factors as the strength of the evidence on 
    toxicity, the nature of the effects that may occur (e.g., death vs. 
    reversible effects), and the likely numbers of individuals exposed and 
    the levels of exposure.
        The House Report points out that the unreasonable risk standard is 
    flexible enough to allow EPA to calibrate the stringency of a 
    regulatory measure to the levels of risks and benefits. Thus, a testing 
    rule, because it does not deprive the public of the benefits of a 
    chemical, requires a lesser showing of harm compared to a rule which 
    may remove a substance from the market or impose other restrictions on 
    its availability. Similarly, a stronger showing would be required to 
    ban an activity than to impose lesser restrictions on use or a 
    requirement, such as labelling, that does not restrict directly.
        The greater the probability and the more severe the potential harm 
    presented by an activity EPA may allow, the less likely a no 
    unreasonable risk finding can be made. Similarly, the greater the 
    benefit of the activity, the greater the risk to be tolerated. 
    Determinations of whether an exemption should be partial or full will 
    depend on the probability and severity of the harm and the benefits to 
    be derived from the activity. Less restrictions should apply if there 
    are substantial benefits from the activity and the probability of harm 
    appears to be lower or the consequences are of low concern.
        b. Summary of section 5(h)(4) exemptions. EPA is proposing to use 
    its authority under TSCA section 5(h)(4) to establish six separate 
    types of exemptions. These are partial exemptions that involve limited 
    reporting and/or recordkeeping for new microorganisms that meet the 
    eligibility requirements of the specific exemptions. Five of these 
    exemptions specifically relate to R&D activities. The sixth case is a 
    tiered exemption for general commercial use.
        Because each exemption involves a different set of issues, each 
    exemption requires a different weighing of risks and product benefits. 
    The remainder of this unit sets out the no unreasonable risk findings 
    for each of the exemptions. For each exemption, a review of the 
    relevant scientific risk considerations is followed by a discussion of 
    the social and economic benefits resulting from microbiological 
    products. The extent to which both risks and benefits are considered is 
    dependent on the breadth of the exemption.
        2. Alternative finding of no unreasonable risk for microorganisms 
    used for R&D in contained structures. The reasoning for this 
    alternative finding relies on the factors discussed in Unit III.B. of 
    this preamble for research that meets the criteria at proposed 
    Secs. 725.234 and 725.235 for R&D conducted in contained structures. 
    See Unit III.B. of this preamble for a full discussion of the rationale 
    for exempting research in contained structures.
        3. Deferral to other Federal authorities for oversight of R&D. Unit 
    II.D. of this preamble describes a proposed exemption from this 
    regulation for research controlled by other federal authorities. This 
    section provides EPA's reasons for establishing this exemption. The 
    exemption is based on the general policy that TSCA should not apply to 
    research adequately overseen by other federal authorities.
        TSCA jurisdiction is discussed in Unit I.C. of this preamble. 
    Generally microorganisms controlled by other Federal agency 
    authorities, other than those microorganisms regulated under FIFRA or 
    FDA authorities, are also subject to TSCA. Agencies, such as the Animal 
    and Plant Health Inspection Service (APHIS) of the U.S. Department of 
    Agriculture (USDA), have regulatory authority that overlaps TSCA 
    authority for microorganisms. Research subject to TSCA may also be 
    funded by Federal agencies, such as the Department of Defense (DOD), 
    the Department of Energy (DOE), the National Institutes of Health 
    (NIH), the National Science Foundation (NSF), USDA's APHIS or its 
    Office of Science and Education (S&E), or EPA's own Office of Research 
    and Development (EPA/ORD).
        On November 23, 1976, all Federal agencies represented on the 
    Federal Interagency Committee endorsed the NIH Guidelines. Departments 
    which support or conduct laboratory rDNA research agreed to abide by 
    the Guidelines in June 1983 (48 FR 24577). Because of the 1983 
    agreement, as a condition for Federal funding of rDNA laboratory 
    research, institutions must ensure that all rDNA research conducted at 
    or sponsored by the institution, regardless of the source of the 
    funding, complies with the Guidelines.
        a. Finding of no unreasonable risk for R&D in contained structures 
    subject to the authority of other Federal agencies. This proposed rule 
    would provide an exemption for research in contained structures 
    (principally laboratories) covered by the NIH Guidelines. EPA considers 
    the NIH Guidelines to provide the primary standard for laboratory 
    research. EPA's rules are designed to provide complementary oversight 
    of those activities not covered by NIH. As a result, EPA is proposing a 
    complete exemption under TSCA section 5(h)(4) for research on new 
    microorganisms in contained structures, if the researcher is required 
    to comply with the NIH Guidelines. This may be achieved through direct 
    regulatory authority or through requiring recipients of Federal funds 
    to comply with the NIH Guidelines. Without this exemption, the 
    recordkeeping and employee notification requirements of proposed 
    Secs. 725.234 and 725.235 would apply to this research. EPA's summary 
    analysis of the NIH Guidelines may be found in the docket which 
    supports this rulemaking.
        EPA proposes under TSCA section 5(h)(4) to exempt from the 
    requirements described in proposed Secs. 725.234 and 725.235 the 
    manufacturers, producers and importers of new microorganisms for R&D in 
    contained structures, if the research is regulated or funded by a 
    Federal agency which has agreed to abide by the NIH Guidelines.
        The pertinent parts of EPA's regulations applying to R&D in 
    contained structures are Sec. 725.234(b) and (d). They require a 
    technically qualified individual (TQI) to maintain documentation that 
    describes the selection of containment and inactivation procedures and 
    ensures the procedures are followed. The TQI's selections must be 
    approved and certified by an authorized official of the institution 
    conducting the experiment (Sec. 725.234(d)(2)). EPA may request the 
    records, review containment/inactivation controls and may order changes 
    in containment/inactivation procedures (Sec. 725.234(d)(3) and (d)(4)).
        These provisions are designed to complement the NIH Guidelines and 
    extend their benefits, without imposing an overly rigid regulatory 
    regime. EPA's regulation is in the same spirit as the NIH Guidelines in 
    that it is also based on the fact that all conceivable experiments 
    cannot be foreseen and that it is the responsibility of the 
    experimenting institution to devise appropriate containment. Like NIH, 
    EPA emphasizes the importance of the motivation and good judgment of 
    the investigators.
        Because the NIH Guidelines are very well entrenched in the research 
    community, EPA expects that the procedures chosen by the TQI will very 
    closely follow the Guidelines. In addition, any EPA review of records 
    will rely heavily on the Guidelines. Thus, by establishing the 
    provisions of proposed Sec. 725.234(d), EPA would effectively apply 
    Guideline principles to those institutions, primarily commercial 
    facilities, that are not required to abide by them. This would 
    complement the NIH request for voluntary compliance.
        Further, the NIH Guidelines apply directly only to those 
    microorganisms, and categories of microorganisms, that have been listed 
    in the Guidelines and, in particular, Guideline Appendices A through F. 
    Other microorganisms would require specific review by NIH. EPA 
    regulations extend the benefits of the NIH Guidelines by effectively 
    applying their principles to microorganisms other than those 
    specifically mentioned in the Guidelines.
        At the same time, by not incorporating the Guidelines directly into 
    regulations, EPA would avoid overly rigid adherence to Guidelines that 
    are, themselves, meant to be flexible. EPA, however, retains sufficient 
    control to protect against risk by the review procedures in proposed 
    Sec. 725.234(d)(3) and (d)(4).
        Requiring researchers to adhere to the proposed requirements of 
    Secs. 725.234 and 725.235 as well as to the requirements of these other 
    federal authorities would be a duplication of oversight and enforcement 
    that would unnecessarily restrict potentially beneficial research 
    without any incremental reduction in potential risk. Thus, there would 
    be no increase in risk from removing the TSCA section 5 restrictions 
    placed on contained structure R&D. Further, costs will be reduced, 
    because there would be no costs incurred in complying with TSCA. R&D 
    would be encouraged without an attendant increase in risk. Therefore, 
    the risks of exempting this research from the TSCA section 5 contained 
    structure R&D restrictions are far outweighed by the costs saved. 
    Accordingly, EPA finds there will be no unreasonable risk from this 
    exemption.
        b. Federal agency R&D subject to TERA reporting. EPA has also 
    considered how it might use its TSCA section 5(h)(4) exemption 
    authority to minimize duplicative reviews of environmental release 
    tests that are also subject to other Federal agencies. EPA has 
    determined that a different exemption process should apply to 
    experiments in the environment than to contained experiments. While the 
    NIH Guidelines are recognized as a standard for contained R&D, the same 
    situation does not pertain to R&D activities involving releases to the 
    environment. Accordingly, EPA is planning to propose the procedures 
    outlined below for exemptions from the TERA process for deliberate 
    release experiments reviewed by other Federal agencies.
        With agencies that have clear regulatory authority, EPA would 
    propose to exempt from TSCA section 5 requirements intentional 
    environmental testing of new microorganisms and to defer to the other 
    Federal agency's review, when EPA determines that the other Federal 
    agency's review addresses criteria equivalent to those which would be 
    evaluated under TSCA section 5. When EPA develops such an exemption 
    involving deferral to another Federal agency, it will propose the 
    exemption using notice and comment rulemaking. EPA is currently working 
    with USDA-APHIS to develop an exemption for R&D field tests reviewed by 
    APHIS under the Federal Plant Pest Act and the Plant Quarantine Act and 
    implementing regulations at 7 CFR part 340 and hopes to include such an 
    exemption when the rule is promulgated.
        4. Finding of no unreasonable risk for TERA approval of new 
    microorganisms--a. Background. EPA recognizes that many small-scale 
    tests will not present unreasonable risks and that requirements 
    restricting R&D could stifle innovation contrary to the intent of TSCA. 
    Therefore, under section 5(h)(4) EPA is proposing to conditionally 
    exempt from MCAN notification R&D involving certain new microorganisms. 
    The exemption is conditional, since researchers must submit a TERA.
        EPA's current experience with reviewing PMNs for microorganisms 
    used for R&D in the environment under the 1986 Policy Statement has 
    indicated that EPA could more efficiently review these activities. 
    While the current process provides an adequate mechanism, R&D 
    activities present a very different risk assessment situation than 
    general commercial use. Differences in exposure, the ability to apply 
    procedures for controlling routes of exposure or dissemination and the 
    procedures for controlling potential risks, and the need for 
    flexibility in R&D comprise different risk assessment scenarios than 
    found in general commercial use. As a result, in light of these 
    different scenarios, a more straightforward and flexible approach to 
    reviewing experiments for new microorganisms is indicated. The TERA 
    provisions of this proposed rule will provide such an approach.
        A TERA provides for submission of information commensurate with the 
    nature of the R&D process, because the review is focused on a specific 
    R&D activity. Therefore, not as much information is required compared 
    to a MCAN. For example, persons who submit a TERA would not have to 
    include information on all commercial manufacture, processing, 
    transport, use, and disposal activities that may involve the new 
    microorganism as is the case for a MCAN.
        The more flexible deadlines and procedures for the TERA would avoid 
    unnecessary delays or restrictions on experiments. TSCA imposes a 90-
    day waiting period for section 5(a)(1) screening; and persons who 
    submit MCANs must wait at least 90 days before an activity can begin, 
    even if EPA should determine no unreasonable risk is posed by the 
    activity before the 90-day review period expires. A similar waiting 
    period may not be appropriate for experiments when more rapid decisions 
    can be made. If TERA review shows that an experiment poses little or no 
    risk, EPA could notify the submitter to proceed at any time during the 
    review period prior to expiration of the review clock.
        b. No unreasonable risk determination. EPA has decided that case-
    by-case review is required to determine the potential risk presented by 
    a microorganism which may establish in the environment during the 
    course of a field trial. The review would allow EPA to determine if it 
    would be necessary to set limitations to minimize the probability of 
    establishment and dissemination in the environment. Microorganisms 
    intentionally tested in the environment are more likely to be 
    acclimated to the environment into which they are introduced, be 
    physiologically fit enough to be competitive in that environment for a 
    significant period of time, and be placed in an area suitable for 
    growth and persistence. Researchers generally apply large numbers of 
    microorganisms to ensure that they persist long enough and compete well 
    enough to perform the function the researcher intends to study. This 
    fact increases the probability that microorganisms used under these 
    conditions could establish and possibly pose a risk or result in 
    significant exposure. Therefore EPA has concluded that R&D which 
    involves intentional testing of microorganisms in the environment 
    should be subject to some review.
        EPA has balanced a number of considerations to determine that 
    experiments reviewed under a TERA will not present an unreasonable risk 
    to health or the environment and should be exempt from MCAN 
    requirements. First, TERA review should result in no greater risks than 
    those that might occur as a result of the MCAN process, because the no 
    unreasonable risk criteria for approval are the same for either 
    process. Second, TERA review may even reduce risks in some instances by 
    allowing EPA to focus resources on activities that may pose the 
    greatest potential for risk. Third, TERA review will reduce reporting 
    costs by eliminating Agency need for information and procedures that 
    are unnecessary for R&D. Fourth, when compared to the MCAN process, 
    TERAs should encourage technological innovation and have a beneficial 
    effect on small businesses engaged in R&D utilizing new microorganisms.
        5. Finding of no unreasonable risk for microorganisms proposed for 
    exemption from TERA reporting. EPA recognizes that some field 
    experiments with new microorganisms do not need to be reviewed at all. 
    EPA therefore intends to exempt from review some R&D experiments with 
    certain new microorganisms. EPA will, however, still review any general 
    commercial uses of these new microorganisms through the MCAN process. 
    The no unreasonable risk finding for exemption from TERA reporting is 
    based on the interaction of three principal criteria addressing the 
    recipient species, the introduced genetic material, and procedures for 
    limiting exposure during experimental use. The three criteria must be 
    considered in concert, because any potential concerns raised in one set 
    of criteria may be balanced or compensated by other criteria. These 
    criteria are discussed in more detail in Unit III.C.7. of this 
    preamble.
        EPA requests comment on whether this approach should be used to 
    exempt from TERA screening certain new microorganisms. EPA is proposing 
    certain intergeneric strains of Bradyrhizobium japonicum and Rhizobium 
    meliloti as candidates for exemption from TERA review, based on reviews 
    of voluntary PMNs submitted under the 1986 Policy Statement and field 
    test data generated in these field trials. Persons possessing 
    information which they believe would support an exemption from TERA 
    reporting for other new microorganisms may use the procedures in 
    proposed Sec. 725.67 to apply for such an exemption.
        EPA proposes to list Bradyrhizobium japonicum and Rhizobium 
    meliloti as acceptable recipient species. Both are well-characterized 
    taxonomically and have been used in the environment for over 80 years 
    to improve nitrogen fixation in specific agricultural crops. There is 
    extensive information on these two species documenting the lack of 
    adverse effects in the environment, and no reports exist that they are 
    pathogenic to humans or animals. In addition, EPA has reviewed field 
    test data from several experiments which have demonstrated that the 
    intergeneric strains are similar to the unmodified parental strains in 
    colonization, survival, nodulation and effects on plant growth. The 
    public dockets pertaining to the reviews of B. japonicum (six strains: 
    P88-1275 through 1278, and P89-340 and 341) and R. meliloti (18 
    strains: P87-568 through 570, P88-1115 through 1122, P89-280, P90-339, 
    and P92-399 through 403), along with the field test data, are 
    incorporated into the docket for this rulemaking. These strains were 
    modified in antibiotic resistance traits, and some were modified for 
    nitrogen fixation traits as well. In the course of these reviews, EPA 
    evaluated general and specific information in the open scientific 
    literature concerning these species, and BSAC subcommittees were 
    convened to discuss general issues associated with the proposed R&D 
    experiments with these strains.
        Modification of traits, the second criterion, limits the source of 
    the introduced genetic material to the genera of Rhizobium and 
    Bradyrhizobium but allows the introduction of antibiotic resistance 
    traits from any source organism. In addition, the introduced genetic 
    material must be poorly mobilizable. The introduction of genetic 
    material for traits other than antibiotic resistance is limited to 
    Bradyrhizobium and Rhizobium species, because EPA is most familiar with 
    these two genera.
        Based on the results of the field tests with these strains, EPA 
    proposes to exempt the use of well-characterized, limited in size, and 
    poorly mobilizable antibiotic resistance markers in Bradyrhizobium 
    japonicum and Rhizobium meliloti. EPA believes that there would be no 
    significant risk resulting from small-scale field tests with the 
    resulting microorganisms containing antibiotic resistance, because 
    broad antibiotic resistance already exists in naturally occurring 
    microorganisms of these two species (as demonstrated in the data 
    submitted for PMNs P88-1115 (rhizobia) and P88-1275 (bradyrhizobia). In 
    addition, higher levels of antibiotic resistance can be easily induced 
    in these microorganisms by mutation or selection. EPA requests comment 
    on the appropriateness of exempting antibiotic resistance traits.
        EPA is proposing that these exemptions would only apply to test 
    sites of 10 acres or less. This test area limit for Bradyrhizobium 
    japonicum and Rhizobium meliloti is based on the field data reviewed by 
    EPA which show that such releases have remained small-scale, with the 
    modified strains exhibiting survival and persistence similar to their 
    unmodified parental strains. The TQI must select appropriate methods to 
    limit dissemination of these modified rhizobial species in order to 
    maintain the small-scale nature of the field tests. Also, this proposal 
    is based on the lack of adverse effects observed in humans and animals 
    resulting from use of these naturally occurring rhizobial species.
        EPA is proposing to exempt intergeneric strains of these two 
    rhizobia species, in order to facilitate research using these 
    microorganisms and to encourage development of products that could 
    increase crop productivity while decreasing dependance on chemical 
    fertilizers. These experiments could generate important information 
    that will increase understanding of the environmental fate of 
    intergeneric microorganisms. Information from these field tests would 
    advance the understanding of microbial ecology, which could facilitate 
    review of commercial products. The possible risks due to exempting 
    these two rhizobia species from review at small-scale will be balanced 
    by the innovation and development of safer, environmentally sound 
    products to promote crop production.
        6. Finding of no unreasonable risk for specific alternative 
    exemption for low risk field tests. Unit II.D. of this preamble 
    describes an alternative exemption from TERA reporting for certain R&D 
    field tests. While EPA acknowledges that parts of the rationale offered 
    in Unit III.B. of this preamble for exempting research conducted under 
    the proposed contained structures exemption could be applied to some 
    small-scale field tests involving microorganisms, EPA does not believe 
    that the rationale can be applied to small-scale field tests as a 
    class. Therefore, it was suggested that EPA define a class of small-
    scale field tests which would be expected to pose low risks and be 
    exempt from TERA reporting. The no unreasonable risk finding for this 
    alternative exemption from TERA reporting is based on the interaction 
    of three primary criteria which consider the safety of the parent 
    microorganism, the role of the traits that have been modified, and the 
    scale of the field tests. If the parent microorganism is shown to have 
    a history of safe use, introduced genetic material meeting the 
    specified criteria would be unlikely to significantly increase the 
    potential for adverse effects. EPA would expect that TQIs would use the 
    criteria discussed in III.C.7. of this preamble for the recipient 
    microorganism and the introduced genetic material as guidance in 
    determining that their new microorganisms would be eligible for this 
    exemption. As in the contained structures exemption for R&D, EPA is 
    relying on the experience and judgement of the TQI to select 
    appropriate methods to limit dissemination of the new microorganisms in 
    order to maintain the small-scale nature of the field tests. Reliance 
    on the judgement of the TQI is discussed further in Unit III.B. of this 
    preamble. EPA believes that the criteria it has specified circumscribe 
    a category of field tests which can be considered low risk. In 
    addition, should EPA receive a notice for a planned field test which 
    did not appear to be low risk, EPA could require the submission of a 
    TERA in order to review more completely the proposal.
        EPA believes that the field tests potentially eligible for this 
    alternative exemption could generate important information which will 
    generally advance the understanding of microbial ecology and 
    specifically facilitate EPA's review of intergeneric microorganisms. 
    The low risks posed by the field tests will be balanced by benefits in 
    the form of reduction in reporting burden for researchers and the 
    encouragement of innovation in the development of environmentally sound 
    products. EPA would like to receive public comment on whether the 
    benefits of this exemption outweigh the potential risks posed by small-
    scale field tests eligible for the exemption.
        Although field tests which meet the proposed criteria would be 
    considered to pose low risks, additional concerns could be raised for 
    unlimited uses of the same microorganisms at the general commercial use 
    stage. Once development of these microorganisms moves beyond R&D to 
    general commercial use, they would be subject to the MCAN reporting 
    requirements discussed in Unit II.C. of this preamble.
        7. Finding of no unreasonable risk for new microorganisms eligible 
    for tiered commercial use exemption. EPA recognizes that some 
    microorganisms present a low risk when used under specific conditions 
    at general commercial use. Therefore, EPA is proposing expedited 
    processes for certain microorganisms at the general commercial use 
    stage. The requirements and processes for the Tier I and Tier II 
    exemptions are discussed in Unit II.C. of this preamble. The criteria 
    for Tier I and Tier II exemptions address: (1) The recipient 
    microorganism; (2) the introduced genetic material; and (3) performance 
    based standards for minimizing the numbers of microorganisms emitted 
    from the manufacturing facility.
        To evaluate the potential for unreasonable risk to human health or 
    the environment in developing these exemptions, EPA focused primarily 
    on the characteristics of the recipient microorganisms. If the 
    recipient is shown to have little or no potential for adverse effects, 
    introduced genetic material meeting the specified criteria would not 
    likely significantly increase potential for adverse effects. As further 
    assurance that risks would be low, EPA is also specifying procedures 
    for minimizing numbers of organisms emitted from the facility. When 
    balanced against resource savings for society and expected product 
    benefits, these exemptions will not present unreasonable risks.
        a. The recipient microorganism. Six criteria were used to determine 
    eligibility of recipient microorganisms for the tiered exemption. 
    First, it should be possible to clearly identify and classify the 
    microorganism. Available genotypic and phenotypic information should 
    allow the microorganism to be assigned without confusion to an existing 
    taxon which is easily recognized. Second, information should be 
    available to evaluate the relationship of the microorganism to any 
    other closely related microorganisms which have a potential for adverse 
    effects on human health or the environment. Third, there should be a 
    history of safe commercial use for the microorganism. Fourth, the 
    commercial uses should indicate that the microorganism products might 
    be subject to TSCA jurisdiction. Fifth, studies are available which 
    indicate the potential for the microorganism to cause adverse effects 
    on human health and the environment. Sixth, studies are available which 
    indicate the survival characteristics of the microorganism in the 
    environment. EPA requests comment on whether these are the appropriate 
    criteria to consider to determine the eligibility of recipient 
    microorganisms for the tiered exemption. After each microorganism was 
    reviewed using the six evaluation criteria, a decision was made to 
    place the microorganism on the list in proposed Sec. 725.420. Summaries 
    of the individual risk assessments, are discussed below. The full risk 
    assessments for the recipient microorganisms are in the docket for this 
    proposed rulemaking.
        (i) Acetobacter aceti is an obligate aerobic bacterium naturally 
    found in the restrictive niche of fermenting fruit, where it can 
    tolerate and utilize ethanol as a nutrient. This species has no 
    recorded pathogenicity on plants, humans, or animals and has a history 
    of safe industrial use. A. aceti is well-defined taxonomically and 
    clearly distinguished from other Acetobacter species known to cause the 
    browning of processed fruit. While it can be expected to survive in the 
    environment, A. aceti is unlikely to cause any significant 
    environmental effects.
        (ii) Aspergillus niger is an asexual fungus commonly found 
    degrading organic matter in nature. This organism has a history of safe 
    use for the production of citric acid and several enzymes. It has been 
    shown to be an opportunistic human pathogen and to damage several 
    species of plants. While production of certain mycotoxins has been 
    associated with strains of A. niger, companies have been using 
    naturally occurring strains of A. niger to produce a variety of 
    products for many years without reports of toxic effects of workers. 
    The limited in size constraints as well as the restriction on 
    vertebrate toxins imposed on introduced genetic material by the 
    criteria for the tiered exemption should reduce the likelihood of 
    increased production or exposure to malformins A and C, the two most 
    potent mycotoxins potentially produced by A. niger strains. In general, 
    the restrictions placed on the introduced DNA and containment mean that 
    the recombinant A. niger strains eligible for the tiered exemption 
    should pose no greater risks than naturally occurring strains of A. 
    niger.
        (iii) Aspergillus oryzae is an asexual fungus found in nature and 
    used for hundreds of years in the production of soy sauce, miso and 
    sake without recorded incidents. This fungus has no reported adverse 
    effects on either plants or animals. It has been suggested that genetic 
    engineering of A. oryzae might inadvertently produce an aflatoxigenic 
    strain. Naturally occurring strains of A. oryzae are not known to 
    produce aflatoxins; however, some scientists believe that A. oryzae is 
    a domesticated version of A. flavus and may possess dormant genes for 
    aflatoxin production. It is likely that companies have already been 
    using genetically modified strains of A. oryzae, but these strains have 
    not yet met the PMN reporting requirements, that is, they are not 
    intergeneric. The limitations placed by the tiered exemption on the 
    introduced genetic material, in particular the well-characterized and 
    limited in size restrictions, should reduce the likelihood that any 
    sequences relating to aflatoxin production could be introduced. The 
    containment requirements would limit exposure to any mycotoxins 
    produced. In addition, A. oryzae does not colonize humans. In general, 
    the restrictions placed on the introduced genetic material and 
    containment mean that the recombinant A. oryzae strains eligible for 
    the tiered exemption should pose no greater risks than naturally 
    occurring strains of A. oryzae.
        (iv) Bacillus licheniformis is an aerobic sporeforming bacterium 
    that is well defined taxonomically. It can be readily isolated from the 
    environment, where it persists primarily as endospores. Many strains 
    have been tested and shown to have no adverse effects on humans, 
    animals or plants. B. licheniformis has been reported as an 
    opportunistic pathogen in livestock; however, it has never been 
    diagnosed as a causal agent. B. licheniformis has a history of safe use 
    in large-scale fermentation production of specialty chemicals and 
    substances such as citric acid and detergent enzymes. Although the 
    majority of experience with industrial fermentations employing B. 
    licheniformis is with asporogenic strains, all strains of this 
    microorganism are being recommended for the tiered exemption.
        (v) Bacillus subtilis is an aerobic sporeforming bacterium which is 
    not completely defined at either the genus or species level. This 
    species is commonly found in nature, particularly in terrestrial 
    environments. Many strains have been tested and shown to have no 
    adverse effects on humans, animals or plants. Reports of B. subtilis 
    acting as an opportunistic pathogen are few in number and have not been 
    well substantiated. B. subtilis has a history of safe use in large-
    scale fermentation production of specialty chemicals and enzymes and 
    even as a source of single cell protein for human consumption in Asia. 
    Although the majority of experience with industrial fermentations 
    employing B. subtilis is with asporogenic strains, all strains of this 
    microorganism are being recommended for the tiered exemption.
        (vi) Clostridium acetobutylicum is an obligate anaerobic endospore-
    forming bacterium which has been isolated from soils, sediments, well 
    water, and from animal and human feces. Various strains of C. 
    acetobutylicum have a history of safe use industrially or in research 
    for the production of butanol and acetone from various feedstocks. 
    While C. acetobutylicum may survive in the environment, it is not 
    likely to cause any significant environmental effects. Although the 
    current taxonomic classification of Clostridium species is not well-
    defined, C. acetobutylicum can be distinguished from closely related 
    species which are known to be human pathogens. In general, the 
    restrictions placed on the introduced genetic material and containment 
    mean that the recombinant C. acetobutylicum strains eligible for the 
    tiered exemption should pose not greater risks that the naturally 
    occurring strains of C. acetobutylicum which have been used in industry 
    without reports of adverse effects to workers or the environment.
        (vii) Escherichia coli K-12 is a strain which is well defined 
    taxonomically, although the genus Escherichia as a whole is not. E. 
    coli K-12 strains can be readily distinguished from those close 
    relatives that are pathogens. E. coli K-12 is a debilitated bacterium 
    which does not normally colonize the human intestine. It has also been 
    shown to survive poorly in the environment, has a history of safe 
    commercial use, and is not known to have adverse effects on humans, 
    microorganisms, or plants. Although some K-12 substrains produce low 
    levels of toxins, toxin expression by these substrains is mitigated by 
    E. coli K-12's poor survival in the environment and its inability to 
    colonize normal human or animal hosts.
        (viii) Penicillium roqueforti is an asexual fungus which decomposes 
    organic materials in nature. Most strains of P. roqueforti, including 
    those used in cheese production, have been shown capable of producing a 
    variety of mycotoxins. P. roqueforti's long history of use in the 
    production of blue cheese has shown no adverse effects. P. roqueforti 
    is generally considered to be a benign organism, but it does raise 
    concerns because of its ability to produce mycotoxins under certain 
    conditions. Despite these concerns, the organism has a history of use 
    without noted reports of adverse effects to workers or the environment. 
    In general, the restrictions placed on the introduced genetic material 
    and containment mean that the recombinant P. roqueforti strains 
    eligible for the tiered exemption should pose no greater risk than 
    naturally occurring strains of P. roqueforti.
        (ix) Saccharomyces cerevisiae is a yeast that occurs commonly in 
    the environment. Although it is not well defined taxonomically and 
    survives well in the environment, it has a history of safe use in the 
    commercial production of many products (e.g., beer). Further, it is not 
    known to cause pathological effects on humans, plants, or animals. S. 
    cerevisiae has no known effects on microorganisms, other than possible 
    effects on strains of its own species.
        (x) Saccharomyces uvarum is a yeast capable of fermenting a variety 
    of sugars into ethanol. S. uvarum has a long history of safe use in 
    production of alcoholic beverages and industrial ethanol. Although it 
    is expected to survive in the environment, it is not expected to cause 
    any adverse environmental effects. While S. uvarum has been used 
    industrially for years, specific strains have not been distinguished.
        b. The introduced genetic material. In order to qualify for either 
    Tier I or Tier II exemption, any introduced genetic material must be 
    limited in size, well-characterized, free of certain nucleotide 
    sequences, and poorly mobilizable.
        (i) Limited in size. Introduced genetic material must be limited in 
    size to those segments required to perform the intended function, as 
    described at proposed Sec. 725.421(a). This criterion reduces 
    uncertainty by excluding the introduction into a recipient of 
    extraneous and potentially uncharacterized genetic material. The 
    requirement that the regulatory sequences permit the expression solely 
    of the structural gene(s) of interest reduces risk by preventing 
    expression of genes downstream of the inserted genetic material. The 
    limitation on the vector sequences that are components of the 
    introduced genetic material prevents the introduction of novel traits 
    beyond those associated with the gene(s) of interest. The overall 
    result of the limited in size criterion is improved ability to predict 
    the behavior of the resulting microorganism. EPA requests comment on 
    the usefulness of this criterion in reducing uncertainty about the 
    behavior of the new microorganism and any difficulties researchers may 
    have in isolating the genetic material required to perform the intended 
    functions.
        (ii) Well-characterized. The requirement at proposed 
    Sec. 725.421(b) that the introduced genetic material be well-
    characterized also contributes to improved ability to predict the 
    behavior of the resulting microorganism. Well characterized includes 
    knowledge of the function of the introduced sequences and the 
    phenotypic expression associated with the introduced genetic material. 
    Genetic material which has been examined at the restriction map or 
    sequence level, but for which a function or phenotypic trait has not 
    yet been ascribed, is not considered well-characterized.
        Well-characterized would include knowing whether multiple reading 
    frames exist within the operon. This relates to whether more than one 
    biological product might be encoded by a single sequence, and addresses 
    the possibility that a modified microorganism could display unpredicted 
    behavior should such multiple reading frames exist and their action not 
    be anticipated.
        (iii) Free of certain sequences. In addition to improving the 
    ability to predict the behavior of the modified microorganism, the 
    well-characterized requirement ensures that segments encoding for 
    either part or the whole of the toxins listed at proposed 
    Sec. 725.421(d) would not inadvertently be introduced into the 
    recipient microorganism (Refs. 11 and 12).
        The toxins listed at proposed Sec. 725.421(d) are polypeptides of 
    relatively high potency. Other types of toxins (e.g., modified amino 
    acids, heterocyclic compounds, complex polysaccharides, glycoproteins, 
    and peptides) are not listed for two reasons. First, their toxicity 
    falls within the range of moderate to low. Second, these types of 
    toxins generally arise from the activity of a number of genes in 
    several metabolic pathways (multigenic).
        In order for a microorganism to produce toxins of multigenic 
    origin, a large number of different sequences would have to be 
    introduced and appropriately expressed. It is unlikely that all of the 
    genetic material necessary for metabolizing multigenic toxins would be 
    inadvertently introduced into a recipient microorganism when 
    requirements that the genetic material be limited in size and well-
    characterized are followed. Should any of the necessary sequences not 
    be introduced, or not be expressed appropriately by the recipient, a 
    toxin of multigenic origin would not be produced. EPA, thus, sees no 
    reason why a manufacturer who wishes to modify a microorganism listed 
    in proposed Sec. 725.420 with a single or a few sequences involved in 
    metabolism of a multigenic toxin should not be allowed to do so. 
    Introduction of a single or a few such sequences into a candidate 
    microorganism should not result in production of a multigenic toxin and 
    thus would not present significant risk.
        Similarly, other properties that might present risk concerns result 
    from the interactive expression of a large number of genes. For 
    example, pathogenic behavior is the result of a large number of genes 
    being appropriately expressed. Because of the complex nature of 
    behaviors such as pathogenicity, the probability is low that an insert 
    consisting of well-characterized, limited in size genetic material 
    could transform the microorganisms listed at proposed Sec. 725.420 into 
    microorganisms which display pathogenic behavior. For this reason, with 
    the exception of certain toxins which are listed because of their 
    potency, EPA is not listing at proposed Sec. 725.421(d) sequences that 
    are one of a series of sequences needed in combination in order for a 
    microorganism to display a complex behavior such as pathogenicity. If 
    commenters believe they can identify sequences which present risk 
    concerns which should be addressed and listed at proposed 
    Sec. 725.421(d), EPA requests they inform the Agency of these 
    sequences.
        (iv) Poorly mobilizable. The requirement, at proposed 
    Sec. 725.421(c), that the introduced genetic material be poorly 
    mobilizable reduces potential for transfer of introduced genetic 
    sequences to other microorganisms in the environment. Such transfers 
    would occur through the interaction of the introduced microorganism 
    with indigenous microorganisms through conjugation, transduction, or 
    transformation. Through such transfers, the introduced genetic material 
    could be transferred to and propagated within different populations of 
    microorganisms, including microorganisms which may never previously 
    have been exposed to this genetic material. It is not possible to 
    predict how the behavior of these potential recipient microorganisms 
    will be affected after uptake and expression of the genetic material.
        Since EPA is not limiting the type of organism that can serve as 
    the source for the introduced genetic material, some limitation is 
    placed on the ability of the introduced genetic material to be 
    transferred. This limitation mitigates risk by significantly reducing 
    the probability that the introduced genetic material would be 
    transferred to and expressed by other microorganisms.
        The transfer frequency of 10-8 was selected as defining 
    ``poorly mobilizable'' for four reasons. First, it represents the lower 
    end of the range of transfer frequencies observed in nature. Transfer 
    of plasmids, for example, commonly occurs through conjugation between 
    bacteria at rates ranging from no detectable transfer (typically less 
    than 10-8 transfer events per donor) to 10-2 transfer events 
    per donor in soil, water and sewage (Ref. 13). A similar range of 
    transfer frequencies has been associated with transduction of 
    chromosomal and plasmid DNA in soil and aquatic microcosms (Refs. 14, 
    15, and 16). Also, a limited number of studies on natural 
    transformation have documented a range of transformation events from 
    0.3 x 10-8 to 1 x 10-8 transformants per recipient (Ref. 17). 
    Second, studies of certain genetic traits (e.g., amino acid auxotrophy, 
    resistance to antibiotics) suggest the spontaneous rate of mutation to 
    be within the range of 10-5 to 10-8 per cell generation 
    (Refs. 18 and 19). A frequency of 10-8 appears to represent, 
    therefore, a baseline frequency at which change occurs in genetic 
    material. Third, this frequency sets the technical limit for 
    measurability. Below the rate of spontaneous mutation, it becomes 
    difficult to distinguish gene transfer from mutation. Fourth, the 
    10-8 criterion should not be difficult to meet, and, in fact, is a 
    standard employed in the NIH Guidelines.
        The 10-8 frequency is attainable given current techniques. 
    Plasmids with transfer rates of 10-8 exist or are easily 
    constructed. In bacteria this low rate is readily engineered through 
    the inactivation of the transfer functions of mobile genetic elements, 
    or the inactivation/removal of pilus formation functions of plasmids 
    (Ref. 20). Some of the plasmids most commonly employed as vectors in 
    genetic engineering (e.g., pBR325 and pBR322) have mobilization/
    transfer frequencies of 10-8 or less. The plasmid pBR322 has been 
    used as a vector to construct several microorganisms reviewed by EPA 
    under the 1986 Policy Statement.
        The criteria set for ``poorly mobilizable'' for transduction and 
    transformation should not prevent most microorganisms from meeting the 
    exemption criteria, since the majority of transfer frequencies reported 
    for transduction and natural transformation are less than 10-8. 
    Higher frequencies are likely only if the introduced genetic material 
    has been altered or selected to enhance frequency.
        Fungal gene transfer has also been considered in development of the 
    poorly mobilizable criterion. Although mobile genetic elements such as 
    transposons, plasmids, and double stranded RNA exist in fungi and can 
    be readily transferred, this transfer usually is only possible between 
    members of the same species during anastomosis, a process specific to 
    fungi. Since anastomosis only occurs between members of the same 
    species, the introduced genetic material would not be transferred to 
    distantly related fungi as may occur with bacteria.
        Based on suggestions made at the July 22, 1991 BSAC Subcommittee 
    meeting, EPA proposes the following definition for ``poorly 
    mobilizable'': ``The ability of the introduced genetic material to be 
    transferred and mobilized is inactivated, with a resulting frequency of 
    transfer of less than 10-8 transfer events per recipient.'' For 
    microorganisms with introduced genetic material associated with 
    conjugative plasmids or conjugative transposons, this criterion can be 
    met by inactivation of transfer or mobilization functions which reduce 
    transfer frequency. In instances where introduced genetic material is 
    located on the chromosome, steps can be taken to insure a low transfer 
    frequency by transduction and transformation by reducing opportunities 
    for illegitimate recombination. EPA requests comment on the 
    appropriateness of its definition of poorly mobilizable and whether 
    there are alternative or additional methods for demonstrating that 
    introduced genetic material is poorly mobilizable that should be 
    included in the definition.
        (v) Effect of introduced genetic material criteria. The 
    requirements placed on the introduced genetic material, in concert with 
    the level of safety associated with the recipient microorganisms, 
    ensure that the resulting microorganisms present low or negligible 
    risk. The probability is low that the insertion of genetic material 
    meeting EPA's criteria into such microorganisms will change their 
    behavior so that they would acquire the potential for causing adverse 
    effects. Risks would be mitigated by the four criteria placed on the 
    introduced genetic material, the relative safety of the microorganisms 
    listed at proposed Sec. 725.420, and the inactivation criteria 
    specified for the Tier I exemption. In the case of Tier II exemption, 
    risks would be mitigated in light of the four criteria placed on 
    introduced genetic material, the relative safety of the microorganisms 
    listed at proposed Sec. 725.420, and EPA's review of the conditions 
    selected.
        c. Standards for minimizing the number of microorganisms emitted 
    from the facility. The standards prescribed for Tier I exemption 
    require that the structure(s) be designed and operated to contain the 
    microorganism, that access to the structure be limited to essential 
    personnel, that inactivation procedures shown to be effective in 
    reducing the number of viable microorganisms in liquid and solid wastes 
    be followed prior to disposal of the wastes, that features to reduce 
    microbial concentrations in aerosols and exhaust gases released from 
    the structure be in place, and that general worker hygiene and 
    protection practices be followed.
        (i) Definition of structure. EPA considers the term ``structure'' 
    to refer to the building or vessel which effectively surrounds and 
    encloses the microorganism. Vessels may have a variety of forms, e.g., 
    cubic, ovoid, cylindrical, or spherical, and may be the fermentation 
    vessel proper or part of the downstream product separation and 
    purification line. All would perform the function of enclosing the 
    microorganism. In general, the material used in the construction of 
    such structure(s) would be impermeable, resistant to corrosion and easy 
    to clean/sterilize. Seams, joints, fittings, associated process piping, 
    fasteners, and other similar elements would be sealed.
        (ii) Standards to minimize microbial release. EPA is proposing, for 
    several reasons, a somewhat cautious approach in prescribing standards 
    for minimizing the number of microorganisms emitted through the 
    disposal of waste and the venting of gases. First, a wide range of 
    behaviors can be displayed by microorganisms modified consistent with 
    EPA's standards for the introduced genetic material. Second, EPA will 
    not conduct any review whatsoever for Tier I exemptions. EPA believes 
    the requirement to minimize emissions will provide a measure of risk 
    reduction necessary for making a finding of no unreasonable risk. Taken 
    together, EPA's standards ensure that the number of microorganisms 
    emitted from the structure is minimized.
        EPA's proposed standards for minimizing emission specify that 
    liquid and solid waste containing the microorganisms be treated to give 
    a validated decrease in viable microbial populations so that at least 
    99.9999 percent of the organisms resulting from the fermentation will 
    be killed. During normal fermentation processes, bacteria generally 
    reach a level of 1010 to 1011 colony forming units per 
    milliliter (Ref. 21). A simple calculation assuming no dilution of the 
    fermentor broth and a minimum inactivation efficiency of 99.9999 
    percent (or a 6 log reduction) results in an estimate of the 
    concentration of viable organisms released from the facility of at most 
    approximately 105 bacteria per milliliter. This number is likely 
    to be lower, since the required reduction is the minimum validated 
    inactivation and the actual kill is likely to be greater.
        Fungi have greater biomass per colony forming unit and therefore 
    are incapable of reaching the high numbers that bacteria in 
    fermentation vats achieve. During the fermentation process, fungal 
    populations frequently reach population densities of 106 to 
    107 microorganisms per milliliter (Ref. 21). The proposed level of 
    inactivation would result in almost all fungi from the fermentation 
    process being rendered nonviable. Here too, the actual reduction in 
    number is likely to be greater that the minimum required by EPA.
        Since the bacteria used in fermentation processes are usually 
    debilitated, either intentionally or through acclimation to industrial 
    fermentation, the small fraction of microorganisms remaining viable 
    after inactivation treatments will likely have a reduced ability to 
    survive during disposal or in the environment. This is because 
    microorganisms repeatedly cultured in specific growth conditions become 
    adapted to those conditions and often lose the ability to survive in 
    different conditions. This is particularly true when microorganisms are 
    used in industrial fermentations wherein most, if not all, of the 
    microorganism's nutritional and other needs are met to ensure rapid 
    growth and good product yield. Moreover, industrial companies, in an 
    attempt to keep their proprietary microorganisms from competitors and 
    to reduce the microbial numbers to those permitted by local sanitation 
    authorities, modify the microorganisms to increase the ability of their 
    microorganisms to survive and perform their assigned tasks in the 
    fermentor but decrease their ability to survive in the environment 
    external to the fermentor.
        When treated wastes are placed in the sanitary sewage line during 
    disposal, factors such as changes in pH, temperature, ionic balance, 
    and dilution adversely affect any microorganisms remaining viable 
    subsequent to inactivation treatment. Similarly, when such wastes are 
    left in the form of cakes for several hours at room temperature, the 
    lack of nutrients and sufficient suitable electron acceptors (oxygen 
    for aerobes, other substances such as an organic compound or sulfur for 
    anaerobes) further reduces viability. Based on these considerations, 
    EPA believes that under its proposed standards, few viable 
    microorganisms will be emitted from the facility through the route of 
    liquid and solid wastes.
        EPA requirements also address microorganisms in the exhaust from 
    the fermentor and along the production line. To address exhaust from 
    fermentors, EPA is proposing that the number of microorganisms in 
    fermentor gases be reduced by at least two logs prior to the gases 
    being exhausted from the fermentor. EPA selected this number based on 
    an estimate of the numbers of microorganisms likely to be in the 
    exhaust from an uncontrolled fermentor and common industry practice. 
    Several studies cited by Battelle (Ref. 22) suggest that a typical 
    viable microorganism load in uncontrolled fermentor exhaust is about 5 
    x 104 organisms per cubic foot. A reduction of two logs would 
    reduce the number to approximately 5 x 102 microorganisms per 
    cubic foot. The actual number is likely to be lower, since the required 
    reduction is a minimum and the number removed may be greater.
        The number of microorganisms that remain viable subsequent to being 
    exhausted from the fermentor is likely to be lower still. First, it is 
    generally not common industry practice to run fermentors in an 
    uncontrolled fashion. Second, microorganisms in fermentor exhausts 
    would be within aerosols. Aerosolization is, in general, very stressful 
    for microorganisms, because of the physical pressures associated with 
    aerosol formation and the high probability of dehydration (Refs. 22 and 
    23). Moreover, microorganisms that are physiologically acclimated to 
    the growth conditions within the fermentor are likely to be compromised 
    in their ability to survive aerosolization. EPA anticipates, therefore, 
    that few microorganisms will survive the stresses of aerosolization 
    associated with being exhausted in a gas from the fermentor. The 
    provision requiring reduction of microorganisms in fermentor exhaust 
    gases contributes to minimizing the number of viable microorganisms 
    emitted from the facility.
        EPA requests comment on whether its standards for minimizing 
    releases of microorganisms from facilities are appropriate for this 
    exemption. EPA is particularly interested in whether commenters can 
    suggest reasonable alternative methods for reducing releases from 
    facilities and provide the rationale for these alternatives.
        EPA is also proposing that the requirements specify that other 
    systems be in place to control dissemination of microorganisms by other 
    routes. This would include programs to control pests such as insects or 
    rats, since these might serve as vectors for carrying microorganisms 
    out of the fermentation facilities.
        (iii) Worker protection. The requirement to minimize microbial 
    emissions, in conjunction with the requirement for general worker 
    safety and hygiene procedures, also affords a measure of protection for 
    workers. Potential effects on workers that exist with microorganisms in 
    general (e.g., allergenicity) will be present with the microorganisms 
    qualifying for this exemption. As with other substances that humans may 
    react to (e.g., pollen, chemicals, dust), the type and degree of 
    allergenic responses is determined by the biology of the exposed 
    individual. It is unlikely that a microorganism modified in keeping 
    with EPA's specifications for the introduced genetic material would 
    induce a heightened response. The general worker hygiene procedures 
    specified by EPA should protect most individuals from the allergenic 
    responses associated with microorganisms exhausted from fermentors and/
    or other substances emitted along the production line. The EPA 
    requirement that entry be limited to essential personnel also addresses 
    this consideration by reducing to a minimum the number of individuals 
    exposed.
        (iv) Guidance for Tier II. EPA is not specifying standards for 
    minimizing the number of microorganisms emitted from the facility for 
    microorganisms qualifying for Tier II exemption. Rather, the Agency 
    requests that submitters utilize as guidance the standards set forth 
    for Tier I procedures. The procedures proposed by the submitter in a 
    Tier II exemption request will be quickly reviewed by the Agency (45 
    days). EPA will have the opportunity to evaluate whether the procedures 
    the submitter intends to implement for reducing the number of organisms 
    emitted from the facility are appropriate for that microorganism.
        d. Benefits of the tiered exemption. Substantial benefits are 
    associated with this proposed exemption. The recipient microorganisms 
    are already widely employed in general commercial uses subject to TSCA 
    reporting. These include microorganisms used to produce enzymes for 
    detergent use or biomass conversion, and production of specific 
    compounds such as plant or microbial growth promoting factors.
        The Agency believes this exemption will result in resource savings 
    both to EPA and industry without compromising the level of risk 
    management afforded by the 90-day MCAN review. The microorganisms named 
    as recipients for the tiered exemption have been assessed for risk, 
    criteria limiting the potential for transfer of and expression of toxin 
    sequences have been provided, and the conditions of use are specified 
    in the exemption (Tier I) or will be reviewed by EPA (Tier II). EPA 
    requirements for minimizing numbers of viable microorganisms emitted 
    are within standard operating procedures for the industry, and both the 
    procedures and the structures specified in the exemption are the type 
    industry uses to protect their products from contamination.
        The exemption will result in reduced reporting costs and a decrease 
    in delay associated with reporting requirements. The savings in Agency 
    resources can be directed to reviewing activities and microorganisms 
    which present greater uncertainty.
        This exemption should facilitate development and manufacturing of 
    new products and the accumulation of useful information. When balanced 
    by the potential resource savings and many industrial benefits of these 
    microorganisms, the Agency finds the potential benefits of exempting 
    uses of these microorganisms under the specific criteria will not 
    present unreasonable risk.
        EPA is considering designating other microorganisms as eligible for 
    this exemption, dependent upon risk assessments for these 
    microorganisms indicating that they present no unreasonable risk under 
    the conditions of use. A list of microorganisms EPA believes are used 
    by industry for TSCA uses appears in a support document in the docket 
    for this rulemaking. EPA plans to evaluate many of these to determine 
    whether they qualify as recipient microorganisms eligible for this 
    exemption. The goal of the evaluation is to ensure that the 
    microorganisms would present no unreasonable risk when used under the 
    conditions of this exemption. Persons possessing information 
    demonstrating no unreasonable risk and thus supporting eligibility for 
    the tiered exemption for these microorganisms or other microorganisms 
    are encouraged to submit such information to EPA to facilitate this 
    process. As noted previously, this information could be submitted using 
    the procedures at proposed Sec. 725.67.
    
    IV. Other Issues
    
    A. Microorganisms Covered in This Rulemaking
    
        1. Microorganisms included. In this proposed rule, EPA, on the 
    advice of its BSAC, is including in its definition of ``microorganism'' 
    those organisms classified in the kingdoms Monera (or Procaryotae), 
    Protista, and Fungi, the Chlorophyta and the Rhodophyta of the Plantae, 
    and viruses and virus-like particles. This definition, which uses the 
    five kingdom classification system of Whittacker (Ref. 24), includes, 
    but is not limited to bacteria, protozoa, fungi, mycoplasmas, 
    mycoplasma-like organisms, spiroplasmas, microphytoplanktons, and green 
    and red algae. Viruses and virus-like particles (e.g viroids, 
    satellites, virusoids) are also considered to be microorganisms by EPA, 
    even though they are classified in a unique classification system 
    described by Francki, et al. (Ref. 25). Should new categories of 
    organisms within the Monera, Protista, Fungi, and the Chlorophyta and 
    the Rhodophyta of the Plantae be identified, these also would be 
    considered microorganisms under this proposed rule. EPA requests 
    comment on its approach to the definition of microorganisms. EPA is 
    particularly interested in comment regarding the appropriateness of 
    including organisms from the Chlorophyta and the Rhodophyta of the 
    Plantae in its microorganism definition.
        The organisms belonging to the Monera, Protista and Fungi are 
    primarily unicellular. Members of the Chlorophyta and the Rhodophyta 
    are also primarily unicellular. As members of the Thallophyta, they 
    show little if any tissue differentiation (the entire plant is known as 
    a thallus), the reproductive structures are often unicellular and lack 
    a protective wall or jacket of sterile cells, and the zygotes do not 
    form embryos within a female reproductive organ. The organisms of the 
    Monera, Protista, Fungi, Chlorophyta, and Rhodophyta may be prokaryotes 
    or eukaryotes, and may or may not possess cell walls.
        Each type of microorganism can be significantly different, one from 
    another. Some measure of the differences between them can be seen in 
    the fact that the descriptor, ``microorganism'', spans four of the five 
    kingdoms into which all organisms are classified. These differences 
    present several challenges in constructing a rule.
        2. Inclusion of viruses and virus-like particles. One important 
    consideration under TSCA revolves around the approach to viruses and 
    virus-like particles. Viruses are included by EPA in the designation 
    ``microorganisms.'' These entities, which are among the smallest of 
    microorganisms, differ from other microorganisms in several ways. 
    First, they are non-cellular entities, lacking a delineating cell 
    membrane and the metabolic machinery for the basic cellular function of 
    energy generation. Second, they contain only one type of genetic 
    informational molecule, either RNA (ribonucleic acid) or DNA 
    (deoxyribonucleic acid). Third, viruses are obligate intracellular 
    inhabitants. They cannot reproduce independently outside of a host 
    cell. For this reason, viruses have historically been identified 
    according to the host they infect, i.e., plant viruses reproduce in 
    plant cells, animal viruses in animal cells, and bacterial viruses in 
    bacterial cells. There are also viruses of fungi, algae, and protozoa. 
    More recently a unique classification system has been developed based 
    on the genome structure and expression, as well as on structural 
    features of the virus particles (Ref. 25). Because their reproduction 
    within cells can result in disruption of the host cell, viruses are 
    generally considered to be pathogens. Viroids are virus-like particles 
    which are also pathogens. These entities are implicated in plant 
    diseases such as potato spindle tuber disease.
        When the BSAC Subcommittee met on July 22, 1991, they considered 
    EPA's approach to microorganisms under TSCA. They raised several issues 
    with regard to viruses and virus-like particles. They noted that 
    viruses are by definition pathogens. As viruses in general have smaller 
    genomes than other microorganisms and a greater percentage of the 
    genome is related to pathogenicity, a change in the viral genome is 
    more likely to affect pathogenicity than a change in the genome of 
    microorganisms such as bacteria and fungi. Even when a change occurs 
    solely within a single genome, viruses and virus-like particles may 
    warrant a more cautious approach than other microorganisms. Finally, 
    plant and animal viruses are known to shift host range under in vitro 
    tissue culture conditions, other unique conditions, or in non-
    traditional hosts, and this, in and of itself, is an important risk 
    consideration.
        Thus, viruses and virus-like particles, because of their unique 
    characteristics, present different issues than other microorganisms. 
    This is particularly true of the viruses that attack macroorganisms 
    (humans, animals, and plants); and the use of these viruses probably 
    warrants scrutiny regardless of whether the virus is new or existing.
        Viruses that infect other microorganisms (e.g., the viruses of 
    protozoa, fungi, and bacteria), may present a somewhat different risk 
    picture from those that infect macroorganisms. Although it appears 
    theoretically possible for a virus of a microorganism (also termed a 
    phage) to permanently eliminate its host microorganism from a habitat, 
    studies done to date do not provide strong evidence that this occurs 
    (Ref. 24), possibly because microorganisms are capable of rapidly 
    developing resistance to phage infection. Phage infections appear 
    rather to result in a temporary fluctuation rather than a permanent 
    change in the numbers of a microorganism in a specific habitat. 
    Moreover, redundancy in function found in natural microbial communities 
    (i.e., many species are capable of performing the same ecological 
    function (Ref. 5)) may cushion the effects of these population fluxes.
        To address viruses for this rulemaking, EPA has distinguished 
    between those that infect microorganisms and those that infect 
    macroorganisms. Phages will be considered MGEs and the MGE guidance 
    discussed in Unit I.C. of this preamble will apply to them. Therefore, 
    a phage which has been modified to contain genetic material from a 
    second phage whose host microorganism is in a different genus than the 
    modified phage would be considered a ``new'' microorganism subject to 
    TSCA section 5 reporting. Similarly, a phage modified to contain 
    genetic material from an organism classified in a different genus than 
    the genus from which the modified (recipient) phage was isolated would 
    be considered intergeneric. Under this interpretation, a phage which 
    has been modified to contain genetic material from a virus of a 
    macroorganism would also be considered a ``new'' microorganism.
        With regard to viruses of macroorganisms, EPA believes that certain 
    viruses of macroorganisms would be subject to TSCA jurisdiction if they 
    were employed in TSCA uses. As discussed in Unit I.C. of this preamble, 
    certain product uses are excluded from coverage under TSCA, the most 
    notable for viruses being the exclusions for pesticides (but not 
    pesticide intermediates) which are covered under FIFRA and for food, 
    drugs, cosmetics, and their intermediates, which are covered by FFDCA. 
    While other uses could potentially be subject to TSCA, EPA has not at 
    this time been able to identify viruses of macroorganisms in uses that 
    might be subject to TSCA. EPA requests comments on whether there are 
    known uses of viruses of macroorganisms that would be subject to TSCA 
    and whether an intergeneric approach such as that used for phages would 
    be appropriate for the viruses of macroorganisms. Comment is also 
    requested on whether EPA's approach for oversight of phages under TSCA 
    section 5 is appropriate.
    
    B. Listing Microorganisms on the Inventory
    
        This Unit describes how EPA proposes to explicitly list 
    microorganisms on the TSCA Inventory after MCAN review and the 
    rationale for the proposed listing.
        1. The components of explicit listing. EPA proposes to identify 
    microorganisms on the Inventory using a taxonomic designation and a 
    consistent set of supplemental information on phenotypic and genotypic 
    traits necessary to identify the microorganism as precisely as 
    possible. EPA expects that this information would be a portion of the 
    information included in MCAN submissions.
        a. Taxonomic designation. The taxonomic designations to the strain 
    level, as appropriate, would be provided for the recipient 
    microorganism and the donor(s) of the introduced genetic material. 
    Taxonomic designations may be those assigned by individual submitters 
    or by a culture collection. The designations would be substantiated by 
    a letter from a culture collection verifying the designation, by 
    literature references, or by the results of tests conducted for the 
    purpose of taxonomic classification. Upon request, the data supporting 
    the taxonomic designation should be provided to EPA. Where possible, 
    the genetic history of the recipient microorganism should be documented 
    back to the isolate from which it was derived.
        b. Supplemental information. Many taxonomic designations at the 
    species level define phenotypically and genotypically diverse groups of 
    microorganisms. Therefore, supplemental information will be used to 
    identify as precisely as possible a specific microorganism on the 
    Inventory. Information on phenotypic and genotypic traits is necessary 
    only to the extent that it assists in the specific identification of 
    the reported microorganism.
        (i) Phenotypic traits. This information concerns the 
    characteristics that reflect the interaction of a microorganism's 
    genotype and the environment in which it is intended to be used. For 
    example, information on intentionally added biochemical and 
    physiological traits is pertinent, since these traits may affect the 
    behavior and fate of a microorganism in the environment. Where 
    possible, submitters should prioritize phenotypic traits in order of 
    those likely to significantly change the microorganism's behavior and 
    thus its potential risk. Such important phenotypic changes may include 
    a change from asporogeny to spore-forming, an increase in the amount of 
    a specific product for which the microorganism is being used as an 
    intermediate, or the activation of a previously inactive enzyme that is 
    known to have negative human health or ecological effects.
        (ii) Genotypic traits. This information concerns the distinguishing 
    genotypic characteristics of a microorganism, including the identity of 
    the genetic material that is introduced into the recipient 
    microorganism and the methods used to construct the reported 
    microorganism. For example, information on the vector construct, 
    cellular location, and number of copies of the introduced genetic 
    material is pertinent, since the vector may add genetic material and 
    traits, and the microorganism's phenotypic traits may be affected by 
    the number of copies and location of the introduced genetic material.
        c. Deposit in a culture collection. Because microorganisms are 
    complex substances and because of the nature of the differences that 
    will be used to distinguish between similar organisms (isolates), EPA 
    is considering requiring that microorganisms listed on the Inventory be 
    deposited in a recognized culture collection. Deposited microorganisms 
    could serve as references for determining whether a related, unreported 
    microorganism, or a subsequently modified, inventoried microorganism is 
    the same as one already listed on the Inventory. Comments on this 
    proposal and alternative suggestions of how to distinguish among 
    closely related microorganisms are requested.
        2. Inventory status of similar and subsequently modified 
    microorganisms. Since publication of the 1986 Policy Statement, EPA has 
    reviewed several intergeneric microorganism PMNs for general commercial 
    use. As discussed previously, the Agency has received an NOC for most 
    of these microorganisms, and these are listed on the TSCA Inventory. 
    The Agency recognizes that subsequent to listing a microorganism on the 
    Inventory, original submitters may make modifications to the genetic 
    material of the inventoried microorganism or companies other than the 
    original submitter may construct microorganisms which may be equivalent 
    to inventoried microorganisms. Questions would arise as to whether the 
    modified microorganism is equivalent to the microorganism listed on the 
    Inventory. At this time, EPA has concluded that no a priori guidance 
    can be given for determining whether a similar strain will be 
    equivalent to one listed on the Inventory. Manufacturers, producers, or 
    importers should consult with EPA concerning the status of their 
    microorganisms, as discussed in Unit II.B.1. of this preamble.
        In making its decision on an individual microorganism, EPA will 
    consider the phenotype of the inventoried microorganism and assess how 
    the subsequent modifications will affect that phenotype. For example, 
    EPA believes that a MCAN may not be required when an inventoried 
    microorganism has undergone certain subsequent modifications of genetic 
    material where these modifications would not be likely to significantly 
    change the microorganism's behavior. The BSAC Subcommittee which met on 
    July 22, 1991, suggested that EPA continue to make these decisions on a 
    case-by-case basis, at least until EPA gains more experience. Although 
    EPA will make its decisions on a case-by-case basis, microorganisms 
    that may be judged by EPA to be equivalent to inventoried 
    microorganisms include those that have experienced deletions, 
    rearrangements, amplifications, point mutations, and/or plasmid loss 
    within a single genome, either spontaneously or through use of chemical 
    or physical mutagens. The Agency recognizes that deletions, 
    rearrangements, amplifications, point mutations, and plasmid loss could 
    occur spontaneously in any microorganism maintained in pure culture, in 
    response to stresses such as freezing or thawing, or as a result of 
    mistakes made during the microorganism's replication of its genetic 
    material.
        EPA recommends that potential submitters consult the Agency for 
    clarification of their reporting obligations whenever additional 
    changes are made to inventoried microorganisms. The Agency has reviewed 
    several bona fide submissions and has determined on a case-by-case 
    basis that the microorganisms described were equivalent to previous PMN 
    submissions. In one case, the microorganism which was the subject of 
    the bona fide submission was derived from the same strain as the 
    inventoried microorganism using similar methods, and intrageneric 
    material encoding the same enzyme function was introduced. Although a 
    small number of base pairs in the intrageneric material had been 
    genetically altered, no new trait was introduced into the bona fide 
    microorganism compared to the inventoried microorganism. In a separate 
    case, the bona fide microorganism contained genetically modified 
    intrageneric material encoding the same function introduced into the 
    inventoried microorganism as well as a small fragment of non-coding, 
    non-regulatory intergeneric genetic material that had been derived from 
    the same source as that introduced into the inventoried microorganism. 
    Although a small number of base pairs had been altered in this 
    intergeneric material, no new trait was present in the bona fide 
    microorganism compared to the inventoried microorganism.
        3. Identification of microorganisms currently listed on the 
    Inventory. EPA wishes to provide manufacturers and processors who are 
    using microorganisms which were listed on the Inventory prior to the 
    1986 Policy Statement the opportunity to provide information for a 
    specific, explicit listing, if necessary. In 1978, when EPA compiled 
    its initial TSCA Inventory, 192 microorganisms were reported. These 
    microorganisms are currently described on the Inventory by taxonomic 
    designations only, without any supplemental information describing how 
    they were made. They are listed in the 1985 Edition, Volume V, of the 
    TSCA Inventory. The list of microorganisms is included in the docket 
    for this rulemaking. The list may be obtained upon request at the 
    address included in the FOR FURTHER INFORMATION CONTACT section of this 
    preamble. EPA believes that most, if not all, of the 192 microorganisms 
    would not be considered new under this proposed rule, since the 
    listings appear to describe microorganisms which are not intergeneric. 
    Thus, these microorganisms would be implicitly included on the 
    Inventory and may continue to be manufactured for general commercial 
    use.
        However, EPA wishes to ensure that all listed microorganisms are 
    described in a consistent manner. Accordingly, EPA advises 
    manufacturers and importers of any of the 192 listed microorganisms to 
    inform EPA of their status under this proposed rule during the public 
    comment period. Any manufacturers of microorganisms that would be 
    considered new under any final rules will be given the opportunity to 
    provide information to EPA to ensure consistent listing of the 
    microorganisms on the Inventory. If EPA is not notified about a 
    microorganism, the Agency will assume it would be implicitly included 
    because it is not intergeneric, and it will be removed from the 
    Inventory list as an explicit listing under EPA's TSCA section 8(b) 
    authority.
        As discussed previously, EPA has reviewed a number of intergeneric 
    microorganism PMNs under the 1986 Policy Statement and has listed the 
    microorganisms on the Inventory. These microorganisms will be retained 
    on the Inventory if the proposal becomes final. If changes are made 
    which require alteration of Inventory listings, EPA will announce them 
    in the Federal Register.
    
    C. SNUR Process
    
        EPA is not proposing any significant new use rules (SNURs) in this 
    document. Instead, EPA is proposing, in subpart L of part 725, 
    procedures to enable it to issue SNURs in the future. Microorganisms 
    subject to SNUR reporting would be listed in proposed subpart M of part 
    725. This Unit discusses the SNUR process that EPA is proposing. This 
    process is adapted from the process in place for traditional chemicals 
    in part 721 with only slight modifications.
        1. SNURs applied to microorganisms. Although EPA is not proposing 
    SNURs for any microorganisms in this document, it is conceivable that, 
    in the future, certain specific uses of microorganisms may raise 
    concerns for human health or the environment. Because the behavior of a 
    specific microorganism is influenced by the environment into which it 
    is introduced (Refs. 5, 7, 8, and 9), it may be necessary to evaluate 
    the risk of some microorganisms when the environment of use is changed. 
    For example, EPA was asked whether any uses of ``Ice +'' strains of 
    Pseudomonas syringae might be subject to SNUR reporting. At the time, 
    the ``Ice +'' microorganism was being used for snowmaking at ski 
    resorts. In that situation, EPA decided that terrestrial uses of the 
    microorganism for such activities as snowmaking at ski resorts, 
    icemaking at ice skating rinks, commercial air conditioning, and spray-
    ice construction applications did not pose significantly different 
    exposures and therefore would not require SNUR reporting to EPA. 
    However, EPA did indicate that because use of the microorganism for 
    cloudseeding would present a significantly different exposure scenario 
    than the terrestrial uses, EPA might require SNUR reporting prior to 
    use of the live microorganism for cloudseeding. In such cases, EPA 
    believes it may be appropriate to use SNUR authority to monitor the 
    commercial development of these substances so that EPA can be apprised 
    of significant increases in exposure potential or significant changes 
    in exposure patterns. These significant increases may warrant control 
    measures or testing. As noted earlier, the MCAN submission and review 
    process will be used for microorganisms subject to SNUR reporting.
        2. Expedited process for issuing SNURs. If EPA finds it necessary 
    to issue SNURs for new microorganisms reviewed under the MCAN process, 
    EPA will use, when appropriate, expedited procedures based on those 
    established in part 721, subpart D. The procedures for issuing 
    expedited SNURs for microorganisms are set forth in proposed 
    Sec. 725.980. EPA is not soliciting separate public comment on these 
    procedures, since they have already been adopted by EPA. This section 
    relies on the rationale originally stated in the Federal Register 
    notices establishing the expedited SNUR process for other new 
    substances under part 721. The SNUR procedures are discussed here and 
    included in the regulatory text for completeness, so that the public 
    will understand all the regulatory provisions potentially applicable to 
    microorganisms.
        A limited amount of toxicity data is typically submitted with 
    premanufacture notifications (PMNs) for chemical substances. Thus, EPA 
    often bases its reviews on structure-activity relationships (SARs). 
    MCANs are expected to present similar problems in data gaps, since 
    current knowledge of microbial ecology is limited, and microorganisms 
    subject to TSCA are expected to be used in an ever-expanding variety of 
    applications and thus a multitude of different exposures. Should the 
    Agency determine it does not possess sufficient information to make a 
    risk judgement, EPA could find under TSCA section 5(e) that it had 
    insufficient information to determine whether the new microorganism 
    presents an unreasonable risk of injury to health or the environment. 
    In most such cases, EPA believes that it is appropriate to negotiate a 
    consent order under section 5(e) with the notice submitter to control 
    human exposure and/or environmental releases until test data or other 
    information sufficient to assess adequately the potential hazard become 
    available. Current experience indicates that section 5(e) consent 
    orders for traditional chemicals have specified a variety of control 
    measures. For microorganisms, EPA may place restrictions on site 
    location or size, production volume or method of application, field or 
    laboratory containment procedures, routine or emergency mitigation 
    procedures, or testing procedures.
        Section 5(e) orders are binding on the original notice submitter 
    but do not apply to other manufacturers of the same microorganism. 
    Without additional regulation, other persons can manufacture, import, 
    or process the microorganism without EPA review and without the 
    restrictions imposed on the original MCAN submitter by the section 5(e) 
    order. To limit all manufacturers equally, EPA imposes SNURs.
        Currently, EPA uses its SNUR authority to extend limitations in 
    section 5(e) orders to other manufacturers, importers, and processors 
    of chemical substances. This ensures that the original submitter and 
    subsequent manufacturers, importers, and processors are treated in an 
    equivalent manner. SNURs are framed so that noncompliance with the 
    control measures or other restrictions is defined as a ``significant 
    new use.'' Thus, other manufacturers, importers, and processors of the 
    substances must either observe the SNUR restrictions or submit a notice 
    to EPA at least 90 days before initiating activities that deviate from 
    these restrictions. After receiving and reviewing such a notice, EPA 
    would have the option of either permitting the new use or acting under 
    section 5(e) or (f) to regulate the new submitter's activities. EPA 
    intends to use this same process for microorganisms. In addition to 
    assuring that all manufacturers, importers, and processors are subject 
    to similar reporting requirements and restrictions, expedited SNURs 
    assure that EPA would have an opportunity to review and evaluate data 
    and, when necessary, regulate prospective manufacturers, importers, or 
    processors of a listed microorganism before a significant new use of 
    that microorganism occurs.
    
    D. Confidential Business Information
    
        EPA's confidential business information (CBI) policy is designed to 
    provide effective public participation by making meaningful information 
    available. In developing confidentiality provisions for submissions, 
    EPA has balanced the need to provide nonconfidential information to the 
    public in a reasonable period of time, to obtain the information it 
    needs to respond to FOIA requests, and to allow persons to assert CBI 
    claims with the minimum burden. In developing its position for this 
    rulemaking, EPA has considered its experience reviewing PMNs for 
    traditional chemicals and microorganisms and comments received on its 
    February 1989 FR notice. This Unit discusses the requirements proposed 
    in subpart C of part 725 and the rationale for EPA's proposal.
        1. Assertion of CBI claims. A person may assert a claim of 
    confidentiality for any information submitted to EPA, with certain 
    exceptions. However, submitters are encouraged to minimize the amount 
    of CBI in biotechnology submissions, so that the public may participate 
    as fully as possible in the review process. All CBI claims must be 
    asserted at the time of submission of the information.
        2. Generic information. Submitters who claim microorganism identity 
    and/or use as CBI also must provide generic information for release to 
    the public. By requiring generic identity and use information, EPA 
    would meet its obligation to provide the public with important 
    information related to the potential risks of new microorganisms 
    without revealing CBI. EPA needs this information to prepare Federal 
    Register notices to announce EPA's receipt of submissions or EPA's 
    decisions regarding exemption requests.
        The generic designations must reveal the identity and use of the 
    microorganism to the maximum extent possible without revealing 
    proprietary information. Submitters are encouraged to review EPA's 
    ``Guidelines for the Preparation of Generic Descriptions of 
    Confidential Microorganism Identity and Use'' and consult with EPA 
    regarding appropriate generic information prior to submitting a notice. 
    The guidelines are available from EPA's Environmental Assistance 
    Division (see FOR FURTHER INFORMATION CONTACT Unit). Microorganism 
    identity must be specific enough to allow clear interpretation of any 
    accompanying health and safety data. When the location of the release 
    site is claimed as CBI, a generic description for use must include 
    information regarding the type of environment into which the 
    microorganism will be released.
        3. Identity in health and safety studies. TSCA section 14(b) states 
    that EPA is not prohibited from disclosing health and safety studies of 
    substances for which TSCA section 5 notification is required, unless 
    disclosure reveals confidential information on process or mixture. 
    Historically, the Agency has considered specific chemical identity to 
    be part of a health and safety study, even when it does not appear in 
    the study. However, during the development of the PMN rule, industry 
    expressed substantial concern about the harm of disclosing confidential 
    chemical identities. At that time EPA explored ways of limiting the 
    commercial harm of such disclosure while still meeting the requirements 
    of TSCA section 14(b) and providing the public with adequate 
    information about health and safety studies. The CBI requirements in 
    the final PMN rule reflected EPA's desire to balance these needs (48 FR 
    21722, May 13, 1983).
        EPA has determined that the regulations developed to address 
    chemical identity in health and safety studies can also be applied to 
    microorganism identity. In this regard, if any health and safety 
    information has been submitted for the microorganism in question, the 
    specific microorganism identity will be held confidential only if 
    disclosure would reveal confidential process or mixture information or 
    if the specific microorganism identity is not necessary to interpret 
    any of the information.
        Under this approach, companies that claim specific microorganism 
    identity confidential in their submissions and wish to argue that 
    knowledge of the specific identity is not necessary to interpret their 
    health and safety information are encouraged to choose generic names 
    which are sufficiently specific to allow interpretation of such 
    information. Sufficiently specific generic names will tend to support 
    arguments that disclosure of the specific microorganism identity is not 
    necessary to understand the health and safety information.
        4. Current policy for substantiation of CBI claims. EPA currently 
    requires submitters of all PMNs for new microorganisms to be released 
    to the environment to substantiate confidentiality claims at the time 
    of submission. This includes PMNs for environmental releases of new 
    microorganisms for R&D as well as for general commercial use, but it 
    does not require upfront substantiation of CBI claims in PMNs for 
    closed system uses of new microorganisms. This policy will continue in 
    effect, until a final rule is promulgated for microorganisms. Like the 
    chemicals program, EPA requires that CBI claims in NOCs for 
    microorganisms be reasserted and resubstantiated when the NOC is 
    submitted.
        5. Proposed changes for substantiation of CBI claims--a. 
    Submissions for general commercial uses of microorganisms. To balance 
    the competing needs of opening the review of submissions for 
    microorganisms to public scrutiny and participation while protecting 
    legitimate CBI claims, EPA proposes to require upfront substantiation 
    of CBI claims in all submissions for general commercial uses of 
    microorganisms. EPA will not distinguish between closed system uses and 
    other uses of microorganisms. Anyone submitting a MCAN, a TME, or a 
    Tier II exemption request will be required to substantiate CBI claims 
    at the time of submission. Failure to include substantiation of any CBI 
    claims, by submitting written answers to the questions, will render the 
    submission incomplete; and it will be returned to the submitter.
        EPA believes that the upfront substantiation requirement for CBI 
    claims will impose little burden on submitters of MCANs, TMEs, and Tier 
    II exemption requests. Because MCAN, TME, and Tier II exemption request 
    submitters are ready to put their products on the market, they should 
    be able to justify why it will continue to be necessary to keep certain 
    information confidential. In addition, given the shorter review period 
    for TMEs and Tier II exemption requests, sufficient information may not 
    be made available to the public if upfront substantiation of CBI claims 
    is not required.
        b. TERA submission. With respect to upfront substantiation for 
    TERAs, EPA is proposing two options and asking for public comments on 
    both. In comments in response to the 1989 FR notice, industry groups 
    raised the issue of adequate protection for R&D. Pointing out that R&D 
    activities involving microorganisms will be facing regulatory burdens 
    that are not imposed on chemical R&D, industry groups said that 
    additional burdens combined with insufficient CBI protection at the R&D 
    stage could reduce incentives to innovate. While submitters are 
    particularly concerned about protecting information at the R&D stage, 
    the public is most interested in participating in the reviews of the 
    first environmental releases of new microorganisms. Public interest 
    groups commented that upfront substantiation is essential to allow 
    public access to information in time to participate in reviews. Because 
    EPA recognizes the importance of the interests of both parties, EPA is 
    asking for additional comments on how best to resolve this issue for 
    CBI claims in TERAs.
        (i) Option 1: Require upfront substantiation of all CBI claims in 
    TERAs. EPA is aware that industry believes that this requirement 
    imposes a greater burden on R&D submitters than is necessary. 
    Experience gained by continuing to require upfront substantiation of 
    CBI claims in submissions for R&D activities will help EPA determine 
    whether this requirement improves public access to information. In the 
    meantime, EPA specifically requests comment on how the burden to 
    submitters could be minimized if upfront substantiation of CBI claims 
    in TERAs is promulgated as part of the final rule.
        (ii) Option 2: Do not require upfront substantiation of CBI claims 
    in TERAs. The second option is to adopt the current requirements for 
    chemical PMNs, that is, require CBI substantiation only after the 
    receipt of a FOIA request. EPA is concerned that given the shorter 
    review period for TERAs, insufficient information may be made available 
    to the public if upfront substantiation of CBI claims is not required. 
    For this reason, EPA specifically requests comment on how public access 
    to information could be improved if submitters were not required to 
    provide upfront substantiation of CBI claims in TERAs.
        c. Substantiation questions. EPA's general procedures for 
    processing and reviewing confidentiality claims are published at 40 CFR 
    part 2. The basic points that should be covered in CBI substantiation 
    are set out at 40 CFR Sec. 2.204(e)(4)(i) through (ix). To ensure that 
    substantiation responses are appropriate for submissions involving 
    microorganisms, EPA has developed a more specific set of questions 
    based on the points in 40 CFR part 2. These questions, which are 
    delineated in proposed Sec. 725.94, are designed to reduce the burden 
    of substantiation by focussing the inquiry on points relevant to a 
    biotechnology product.
    
    E. User Fees
    
        Section 26(b) of TSCA provides that EPA may by rule establish fees 
    for persons required to submit data under section 4 or 5 to defray the 
    costs of administering TSCA. EPA must take into account the submitter's 
    ability to pay the fee and the cost of reviewing the submitted data. 
    EPA is using this authority to collect fees for notices submitted on 
    microorganisms.
        EPA regulations already require persons to remit fees to EPA when a 
    PMN or SNUN is submitted to the Agency for review (40 CFR Sec. 700.45). 
    For MCAN submissions, EPA is proposing to amend part 700 to establish a 
    fee of $100 for notifications submitted by small businesses, and $2,500 
    for all other businesses. For purposes of this proposed rule, small 
    businesses are defined as companies with total annual sales of less 
    than $40 million. These proposed fees for MCANs are the same as those 
    set for submissions of PMNs for other chemical substances. EPA believes 
    that its costs of reviewing MCAN notifications will equal or exceed the 
    cost of reviewing PMNs for other chemical substances.
        EPA is not proposing user fees for other submissions under this 
    proposed rule, including TERAs and Tier II exemption requests. EPA is 
    not reopening the general issues applicable to the adoption of user 
    fees for comment in this document, since comments on the subject were 
    addressed in a final rule published in the Federal Register of August 
    17, 1988 (53 FR 31248).
    
    F. Section 8(e) Reporting Requirements
    
        Any person who manufactures, imports, processes, or distributes in 
    commerce a TSCA-covered microorganism, whether new or existing, and/or 
    product(s) therefrom (including a person engaged solely in R&D) is 
    reminded about the statutory responsibility to immediately report to 
    EPA any information the person obtains which reasonably supports the 
    conclusion that such microorganism, or a product therefrom, presents a 
    substantial risk of injury to health or the environment, unless the 
    person has actual knowledge that EPA has been adequately informed 
    already about the information. Guidance regarding the section 8(e) 
    reporting requirement is provided in EPA's section 8(e) policy 
    statement (``Statement of Interpretation and Enforcement Policy; 
    Notification of Substantial Risk'' 43 FR 11110; March 16, 1978) and its 
    technical amendment (52 FR 20083; May 29, 1987). Additional information 
    regarding TSCA section 8(e) reporting is provided in 56 FR 4128 
    (February 1, 1991); 56 FR 19514 (April 26, 1991); 56 FR 28458 (June 20, 
    1991); and 56 FR 49478 (September 30, 1991).
        Should EPA receive a section 8(e) substantial risk notice with 
    respect to the manufacture, importation, processing or distribution in 
    commerce of a microorganism, EPA may proceed to regulate the activity 
    causing the risk. If EPA determines, under authority of TSCA section 7, 
    that the activity or microorganism, including its parts or products, on 
    which a section 8(e) notice was received, is ``imminently hazardous'' 
    to health or the environment, EPA may require immediate suspension of 
    manufacturing, processing or distribution in commerce of the imminently 
    hazardous microorganism. EPA also may require any remediation necessary 
    to obtain permanent relief as may be necessary to protect health or the 
    environment from the unreasonable risks associated with the 
    microorganism. This authority applies to any ``imminently hazardous'' 
    microorganism or its parts or products, regardless of whether the 
    microorganism is used for R&D or manufactured for general commercial 
    use.
        The term ``imminently hazardous chemical substance or mixture'' in 
    TSCA section 7 means a chemical substance or mixture which presents an 
    imminent and unreasonable risk of serious or widespread injury to 
    health or the environment. Such a risk is considered imminent if the 
    manufacture, processing, distribution in commerce, use or disposal of 
    the substance is likely to result in such injury before a final rule 
    can be issued under TSCA section 6.
    
    G. Export Notification and State Preemption
    
        This Unit discusses two other provisions of TSCA concerning export 
    notification and Federal preemption that may be of some concern to the 
    public in implementing this proposed rule.
        1. General. Section 12 of TSCA generally provides that the Act does 
    not apply to chemical substances produced for export. However, section 
    12(b)(2) requires, in pertinent part, that EPA must be notified about 
    the export of any substance in U.S. production that is subject to a 
    rule, an order, or some other relief granted under section 5. EPA must 
    then notify the government of the receiving country. EPA's export 
    notification regulations are codified at 40 CFR part 707.
        Section 18(a) provides that TSCA generally does not preempt the 
    authority of any State or local government to regulate a chemical 
    substance. There are some exceptions, however. In particular, section 
    18(b) states that, if EPA issues a rule or order under section 5 
    ``which is applicable to a chemical substance'' and ``which is designed 
    to protect against a risk of injury...associated with such substance'', 
    no State or local government may issue or continue in effect any 
    requirement designed to protect against the same risk, with certain 
    exceptions. The exceptions are that the State or local requirement may 
    be identical to the Federal requirement, may be issued under authority 
    of another Federal law, or may prohibit use of the substance (other 
    than in the manufacture or processing of another chemical substance or 
    mixture).
        2. Applicability. EPA interprets the exemption of section 12(a) to 
    apply only to those microorganisms manufactured, processed, or 
    distributed solely for export. If the microorganism is manufactured, 
    processed, or distributed for any use in the United States, it is 
    subject to TSCA (see TSCA section 12(a)(1)(A)). Thus, any R&D in the 
    U.S. is subject to applicable regulations, as are any other activities 
    involving a microorganism that are described in this proposed rule. 
    Similarly, any release of microorganisms to the environment prior to 
    export will not be considered solely for export and is therefore 
    subject to applicable regulations.
        Since the rules proposed in this document are either of general 
    applicability and largely procedural, or are exemptions from regulation 
    and only establish procedures to screen against potential risk, neither 
    section 12(b) export notification nor section 18(b) preemption applies 
    at this time.
        Sections 12(b) and 18(b) would apply should EPA decide to take 
    regulatory action against a microorganism or class of microorganisms, 
    for example, by issuing an order under TSCA section 5(e). In such 
    cases, section 12(b) export notification would apply automatically. 
    While preemption under section 18(b) would apply by operation of 
    statute, in individual cases EPA could issue rules that specifically 
    require compliance with applicable State or local requirements.
    
    H. Regulatory Text Overview
    
        The regulatory text comprises the language which EPA is proposing 
    to incorporate into the Code of Federal Regulations (CFR). While the 
    preamble to this proposed rule provides the rationale for EPA's 
    preferred approach towards the oversight of certain activities 
    involving new microorganisms, the regulatory text includes all the 
    proposed requirements to which the regulated community would be 
    subject.
        The regulatory text amends existing regulations regarding the 
    collection of fees from submitters of notices under section 5 of TSCA 
    (40 CFR part 700), to reflect the fee structure for the notices and 
    applications that have been developed by this proposed rule. Additional 
    amendments to parts 720, 721, and 723 consolidate TSCA section 5 review 
    of microorganisms into part 725.
        EPA is proposing to establish a new part 725 of Title 40 of the 
    CFR. EPA believes that consolidating all requirements and procedures 
    applicable to new microorganisms into one part of the CFR is justified 
    because of the differences between microorganisms and other chemical 
    substances.
        The consolidation will benefit the public by providing greater 
    clarity. Part 725 is devoted exclusively to the review of 
    microorganisms under section 5 of TSCA and is currently divided into 
    eight subparts. Subparts A, B, and C consolidate provisions primarily 
    adapted from parts 720 and 721. Subpart A, which includes definitions 
    that are applicable throughout part 725, describes general provisions 
    and applicability. Subpart B describes administrative procedures that 
    are applicable to all submissions under part 725. Subpart C describes 
    confidentiality provisions that are applicable to all submissions under 
    part 725.
        Subpart D, which combines the general PMN and SNUN requirements 
    adapted from parts 720 and 721, describes the reporting requirements 
    and review process pertaining to MCANs. Subparts E, F, and G describe 
    the reporting requirements and review processes for applications for 
    exemptions from full MCAN reporting. Subpart E, which is almost 
    entirely new, describes who is eligible to submit a TERA or receive a 
    TERA list exemption, and what criteria must be met to receive an 
    exemption from EPA review for certain types of R&D activities. Subpart 
    F, which is an adaptation of Sec. 720.38, describes the requirements 
    for a test marketing exemption for microorganisms. Subpart G, which is 
    entirely new, describes what criteria must be met in order to qualify 
    for Tier I or Tier II exemptions for certain microorganisms in general 
    commercial use. Subpart L, which is adapted from part 721, describes 
    additional procedures for reporting significant new uses of 
    microorganisms. Although significant new use rules are not being 
    proposed at this time, it is intended that subpart M will list 
    microorganisms and specific significant new uses when they are 
    promulgated.
    
    I. Rulemaking Process and Public Hearings
    
        EPA is conducting this rulemaking under notice and comment 
    rulemaking procedures. Interested persons have the opportunity to 
    submit written comments to the address identified under the ADDRESSES 
    Unit of this preamble. EPA will carefully consider all such comments.
        EPA is also providing an opportunity for an informal public hearing 
    on the proposed rule. This hearing will be held only if EPA receives a 
    timely written request for such a hearing.
        As a general matter, EPA is not required to hold a public hearing 
    in informal notice and comment rulemaking of this type. However, use of 
    section 5(h)(4) modifies the general rulemaking requirements by 
    referencing TSCA section 6(c)(2) and (3) rulemaking procedures. Under 
    those procedures, EPA must hold an informal public hearing, if 
    requested, and, if properly requested and granted by EPA, allow an 
    opportunity to present rebuttal submissions and conduct cross-
    examinations related to disputed issues of material fact.
        EPA does not anticipate that, even if a hearing is held, there will 
    be a need for rebuttal submissions and crossexamination, because the 
    section 5(h)(4) portion of this proposed rulemaking is based primarily 
    on matters of science policy that do not yield disputed factual issues.
    
    V. Economic Impact and Regulatory Flexibility Analysis
    
    A. Regulatory Impact Analysis
    
        1. Introduction. EPA has prepared a Regulatory Impact Analysis 
    (RIA) assessing the costs, benefits, and associated impacts of 
    regulating new microorganisms under TSCA as set forth in the proposed 
    rule. Though direct regulatory costs attributable to the proposed rule 
    were not estimated to be in excess of $100 million annually, EPA has 
    designated the rule as ``significant'' under Executive Order 12866 
    because it raises novel policy issues arising out of legal mandates. 
    This unit presents a summary of the RIA's key findings and estimates.
        2. Characteristics of the regulated community. Although unable to 
    quantify the exact magnitude of activity in biotechnology sectors 
    affected by this rulemaking, the Agency believes that activities 
    involving microorganisms falling within the scope of the proposed rule 
    comprise a modest share of overall activity. EPA estimates that 
    approximately 130 firms may be involved in commercial R&D or in general 
    commercial use of potentially regulated microorganisms. In terms of 
    revenue, the potentially affected universe appears to be divided 
    sharply between large and small firms. EPA estimates roughly one-half 
    of the companies potentially affected to have annual sales of $40 
    million or more, while most of those remaining are estimated to have 
    sales under $10 million. For many of these firms, however, revenue 
    generated from activities subject to this proposal is believed to 
    represent only a small portion of reported sales. EPA also estimates 
    that approximately 300 universities could be affected by the 
    rulemaking.
        3. Costs to potential submitters. Due to data limitations and the 
    uncertainties associated with projecting future product development 
    activities in biotechnology application areas subject to the proposed 
    rule, EPA's estimates of the costs of compliance associated with this 
    rulemaking action have been only partially quantified. In cases where 
    the Agency was able to generate quantified estimates of compliance 
    costs, information which would have permitted the development of more 
    accurate estimates was frequently unavailable. In such cases, the best 
    available information was used. Estimates are believed to represent a 
    reasonable approximation of actual costs attributable to the rule.
        In assessing the potential cost impact of the proposed rule, EPA 
    focussed on two impact years, the first and fifth years following the 
    time of proposal (assumed to be 1992 and 1996, for the purposes of 
    analysis). This approach was used because of the relative immaturity of 
    the biotechnology sectors potentially subject to the proposed rule and 
    the difficulty in attempting to forecast long-term technological and 
    marketing developments. However, EPA wishes to emphasize that estimated 
    costs could be significantly higher in the long-term, owing to industry 
    growth.
        Four major cost areas were identified, based on an analysis of the 
    requirements of the proposed rule. These areas were costs incurred in 
    preparing various types of notification submissions or documentation; 
    costs incurred in complying with any post review requirements for 
    monitoring or controls that may be imposed by EPA as a result of risk 
    concerns and uncertainties; costs incurred in substantiating 
    confidential business information (CBI) claims; and one-time costs 
    attributable to rule familiarization.
        Incremental costs to industry (industry-wide costs excluding 
    requirements under current policy) were estimated to fall between 
    $890,000 and $2.2 million in year 1 and between $56,000 and $460,000 in 
    year 5. Year 5 costs account for rule familiarization only in the case 
    of new firms entering the affected market areas, and therefore are much 
    less than year 1 costs, where rule familiarization costs were summed 
    over all affected entities.
        Cost impacts on individual products will vary, depending on 
    application area. Submitters qualifying for exemptions in connection 
    with microorganisms intended for general commercial use will realize 
    net savings relative to current reporting requirements. On the other 
    hand, submitters reporting R&D activities involving environmental 
    release may realize an increase in regulatory burden under the proposed 
    rule.
        4. Costs to the Federal government. EPA estimated the potential 
    costs to government associated with the proposed rule. These costs 
    arise in connection with the Agency's processing of individual 
    notification submissions. In estimating government cost impacts, EPA 
    included costs estimated to be incurred in reviewing each submission. 
    EPA professionals and members of the Biotechnology Science Advisory 
    Committee were assumed to be involved in such review. In the event that 
    post-review restrictions would be placed on a specific activity, such 
    as monitoring during a field test, additional costs attributable to the 
    drawing up of regulatory documentation would be incurred.
        Incremental costs to the government were estimated to fall between 
    $115,000 and $122,000 in year 1, while a net savings to EPA, estimated 
    to fall between $39,000 and $184,000, is expected in year 5. These 
    savings arise in connection with the substantial number of full reviews 
    that will be avoided if the exemption provisions of the proposed rule 
    are promulgated.
        5. Benefits of the proposed rule. EPA's regulation of new 
    microorganisms under TSCA provides benefits to society through 
    reduction of the potential for adverse impacts on health and the 
    environment resulting from the use of such microorganisms. This benefit 
    is achieved by screening new microorganisms and, when appropriate, 
    imposing controls on microorganism use to protect society from costly 
    and possibly irreversible damages.
        For microorganisms in general commercial use, risk reduction 
    attributable strictly to the notification requirements of proposed rule 
    would be marginal, as these requirements are based on current policy. 
    However, the proposed rule enhances and contributes to the overall risk 
    reduction potential of the Agency's program under TSCA by providing for 
    a more efficient regulatory strategy relative to current policy, 
    focussing society's resources on those new microorganisms of greatest 
    concern.
        For microorganisms in commercial R&D, a greater proportion of 
    overall risk reduction can be attributed to the proposed rule, since 
    reporting in connection with field experiments has been voluntary since 
    1986. Although the Agency has been receiving voluntary submissions, EPA 
    is not certain whether this practice is universal or whether those 
    filing voluntarily would continue to do so in the absence of this 
    proposed rule.
        Over the long-term, regulation is also likely to encourage 
    development of additional information concerning fate and effects of 
    new microorganisms, to encourage the development of microorganisms 
    which pose low concern for effects on human health and the environment, 
    and to encourage public input into decisions concerning the use of new 
    microorganisms.
        Benefits may also be realized through the proposed rule's potential 
    impact on the pace of product development. A more certain regulatory 
    climate could stimulate business activity, as could a more reassured 
    public. The proposed rule may also reduce the possibility of continued 
    regulatory activity at the State and local level. A national system of 
    potentially uncoordinated rulemaking initiatives could lead to market 
    distortion and could hamper competition.
        6. Effects of the proposed rule on innovative activity. As a result 
    of the proposed rule, members of the regulated community may find 
    product development strategies in connection with certain products to 
    require reassessment. Since impacts of this nature could influence the 
    degree of emphasis a firm places on innovative activity, the potential 
    for innovation impacts was investigated.
        Though great uncertainty regarding regulatory costs and the 
    potential for a particular product's commercial success make it 
    impossible to estimate innovation impacts quantitatively, the effects 
    of added regulatory costs and delays on a product's lifetime cash-flow 
    was examined. More specifically, a number of plausible product 
    development scenarios were modeled incorporating assumptions regarding 
    expenditures and returns over the course of a product's useful life 
    from research to obsolescence. Regulatory burdens were then factored 
    into the models, and profit impacts observed. Impacts realized when 
    total regulatory costs were assumed to reach the upper-bound of EPA's 
    estimated range could result in severe profit reductions in some cases. 
    However, in general, EPA's analysis indicated that impacts should not 
    be prohibitive, particularly when incremental costs are considered. 
    Factors such as length of delay related to regulatory review, return 
    rate, and obsolescence rate all play important roles in determining the 
    impact of EPA's program on innovative activity. These factors are 
    expected to be highly variable and product-specific.
        7. Impacts on small business. EPA survey data suggest that 42 
    percent of companies potentially affected by the proposed rule may be 
    small businesses. Though data were not available allowing the Agency to 
    employ standard criteria for assessing the magnitude of small business 
    impacts, the finding of a substantial portion of the regulated 
    community to be small businesses prompted EPA to develop options to 
    provide relief to such businesses. The options considered include 
    reducing CBI substantiation requirements and the elimination of the 
    $100 filing fee.
    
    B. Request for Comment on Economic Issues
    
        Based on the analysis presented in the RIA, EPA's preliminary 
    findings are that this proposed rule should not adversely affect either 
    innovation or international competitiveness in biotechnology; to the 
    contrary, EPA believes that this proposed rule will provide needed 
    regulatory and procedural clarity under TSCA to enable the U.S. 
    biotechnology industry to commercialize products while ensuring 
    appropriate oversight to protect public health and the environment.
        EPA nevertheless believes that this proposed rule should continue 
    to be evaluated in light of its potential impact on innovation and 
    international competitiveness. To this end, the Agency is requesting 
    public comment regarding the economic impacts associated with this 
    proposed rule. Data or other information are specifically requested in 
    connection with the following: rate of capital acquisition and critical 
    factors affecting R&D capitalization; rate and magnitude of R&D 
    expenditures; data regarding actual submissions under the current 
    policy, e.g., project development costs, regulatory burdens, 
    development schedules and revenues.

    IX. 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 entitlement, 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, EPA has determined 
    that this proposed rule is ``significant'' because it raises novel 
    policy issues arising out of legal mandates. As such, this action was 
    submitted to OMB for review, and any comments or changes made in 
    response to OMB suggestions or recommendations have been documented in 
    the public record.
    
    B. Regulatory Flexibility Act
    
        Under the Regulatory Flexibility Act (5 U.S.C. 605(b)), EPA has 
    analyzed the economic impact of this proposed rule on small businesses. 
    A summary of this analysis appears in Unit V. of this preamble. This 
    proposed rule does not exempt small businesses. Preliminary analysis of 
    the impacts of this proposed rule on small businesses indicates that 
    the compliance costs may have a significant impact. Despite the 
    uncertainties and data gaps faced by EPA in developing this analysis, 
    EPA believes that it is prudent public policy to assume that the 
    requirements of the Regulatory Flexibility Act (Pub. L. 96-354) have 
    been triggered. EPA believes that review of certain new microorganisms 
    under TSCA is important to ensure that there are no unreasonable risks 
    to health and the environment, and that the mechanisms outlined in this 
    proposed rule will lessen impacts on small business as much as 
    possible.
        The Regulatory Impact Analysis section on small business impacts 
    (Section VIII of the RIA, which is part of the public record for this 
    rulemaking) serves as the Initial Regulatory Flexibility Analysis 
    required by the Regulatory Flexibility Act. EPA intends to revise this 
    analysis prior to promulgation of the final rule. EPA requests comments 
    on the methodology employed in this analysis and the results of this 
    analysis.
    
    C. Paperwork Reduction Act
    
        The Office of Management and Budget (OMB) has approved the current 
    Premanufacture Notification and SNUR program under the provisions of 
    the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned 
    OMB control number 2070-0012. This proposed rule, when promulgated, 
    would modify those information collection requirements; an information 
    collection request addressing these modifications has been submitted to 
    OMB under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 
    et seq.
        Public reporting burden for this collection of information is 
    estimated to average 473 hours per response, including time for 
    reviewing instructions, searching existing data sources, gathering and 
    maintaining the data needed, and completing and reviewing the 
    collection of information.
        Send comments regarding the burden estimate or any other aspect of 
    this collection of information, including suggestions for reducing 
    burden, to Chief, Information Policy Branch, 2136, U.S. Environmental 
    Protection Agency, 401 M St., SW., Washington, DC 20460, and to the 
    Office of Information and Regulatory Affairs, Office of Management and 
    Budget, Washington, DC 20503, marked ``Attention: Desk Officer for 
    EPA.'' The final rule will respond to any OMB or public comments on the 
    information collection requirements contained in this proposal.

    Subpart A--General Provisions and Applicability
    
    
    Sec. 725.1  Scope and purpose.
    
        (a) This part establishes reporting requirements under section 5 of 
    TSCA for manufacturers, importers, and processors of microorganisms for 
    commercial purposes.
        (b) TSCA section 5 covers chemical substances as defined under TSCA 
    section 3. Because EPA interprets the section 3 definition to include 
    microorganisms, section 5 also covers microorganisms. Unless otherwise 
    specifically stated in the Code of Federal Regulations, TSCA section 5 
    authority over microorganisms (as distinguished from other chemical 
    substances) will be implemented under this part.
        (c) Microorganisms subject to reporting as new microorganisms will 
    be those which are intergeneric. In addition, any microorganism subject 
    to TSCA jurisdiction may be subject to reporting, if EPA determines by 
    rule that the microorganism is being manufactured, imported, or 
    processed for a significant new use.
        (d) This subpart A describes the general organization for this part 
    and contains definitions generally applicable to this part.
        (e) Subpart B of this part describes general administrative 
    procedures applicable to microorganisms subject to this part.
        (f) Subpart C of this part establishes requirements for handling 
    confidential business information (CBI) and public access to 
    information submitted under this part.
        (g) Subpart D of this part describes the persons and microorganisms 
    subject to Microorganism Commercial Activity Notices (MCANs), 
    prescribes the content of MCANs, and establishes procedures for 
    reviewing MCANs.
        (h) Subpart E of this part establishes reporting requirements and 
    EPA review procedures for the TSCA Experimental Release Application 
    (TERA) for microorganisms intentionally tested in the environment 
    during commercial research and development activities. Subpart E of 
    this part also identifies microorganisms and classes of microorganisms 
    exempt from research and development reporting.
        (i) Subpart F of this part establishes procedures for obtaining 
    test marketing exemptions (TMEs) for microorganisms.
        (j) Subpart G of this part identifies microorganisms in general 
    commercial use under certain conditions of containment that are 
    eligible for Tier I and Tier II exemptions from subpart D reporting. 
    Subpart G of this part establishes reporting requirements and 
    procedures for expedited review of the Tier II exemption request.
        (k) Subpart L of this part describes additional requirements 
    applicable to reporting on microorganisms subject to significant new 
    use rules under TSCA section 5(a)(2). All significant new uses of 
    microorganisms are subject to the MCAN requirements in subpart D of 
    this part.
        (l) Subpart M of this part identifies specific significant new uses 
    of microorganisms subject to subpart D reporting.
    
    
    Sec. 725.3   Definitions.
    
        Definitions in section 3 of the Act (15 U.S.C. 2602), as well as 
    definitions contained in Sec. Sec. 704.3, 720.3, and 721.3 of this 
    chapter, apply to this part unless otherwise specified in this section. 
    In addition, the following definitions apply to this part:
        Consolidated microbial commercial activity notice or consolidated 
    MCAN means any MCAN submitted to EPA that covers more than one 
    microorganism (each being assigned a separate MCAN number by EPA) as a 
    result of a prenotice agreement with EPA.
        Containment and/or inactivation controls means any combination of 
    engineering, mechanical, procedural, or biological controls designed 
    and operated to restrict environmental release of viable microorganisms 
    from a structure.
        Director means the Director of the EPA Office of Pollution 
    Prevention and Toxics.
        Exemption request means any application submitted to EPA under 
    subparts E, F, or G of this part.
        General commercial use means use for commercial purposes other than 
    research and development.
        Genome means the sum total of chromosomal and extrachromosomal 
    genetic material of an isolate and any descendants derived under pure 
    culture conditions from that isolate.
        Health and safety study of a microorganism or health and safety 
    study means any study of any effect of a microorganism or microbial 
    mixture on health or the environment or on both, including underlying 
    data and epidemiological studies, studies of occupational exposure to a 
    microorganism or microbial mixture, toxicological, clinical, and 
    ecological, or other studies of a microorganism or microbial mixture, 
    and any test performed under the Act. Microorganism identity is always 
    part of a health and safety study of a microorganism.
        (1) It is intended that the term ``health and safety study of a 
    microorganism'' be interpreted broadly. Not only is information which 
    arises as a result of a formal, disciplined study included, but other 
    information relating to the effects of a microorganism or microbial 
    mixture on health or the environment is also included. Any data that 
    bear on the effects of a microorganism on health or the environment 
    would be included.
        (2) Examples include:
        (i) Tests for ecological or other environmental effects on 
    invertebrates, fish, or other animals, and plants, including: Acute 
    toxicity tests, chronic toxicity tests, critical life stage tests, 
    behavioral tests, algal growth tests, seed germination tests, plant 
    growth or damage tests, microbial function tests, bioconcentration or 
    bioaccumulation tests, and model ecosystem (microcosm) studies.
        (ii) Long- and short-term tests of mutagenicity, carcinogenicity, 
    or teratogenicity; dermatoxicity; cumulative, additive, and synergistic 
    effects; and acute, subchronic, and chronic effects.
        (iii) Assessments of human and environmental exposure, including 
    workplace exposure, and impacts of a particular microorganism or 
    microbial mixture on the environment, including surveys, tests, and 
    studies of: Survival and transport in air, water, and soil; ability to 
    exchange genetic material with other microorganisms, ability to 
    colonize human or animal guts, and ability to colonize plants.
        (iv) Monitoring data, when they have been aggregated and analyzed 
    to measure the exposure of humans or the environment to a 
    microorganism.
        (v) Any assessments of risk to health and the environment resulting 
    from the manufacture, processing, distribution in commerce, use, or 
    disposal of the microorganism.
        Inactivation means that living microorganisms are rendered 
    nonviable. ``Introduced genetic material'' means genetic material that 
    is added to, and remains as a component of, the genome of the 
    recipient.
        Intergeneric microorganism means a microorganism that is formed by 
    the deliberate combination of genetic material from organisms of 
    different taxonomic genera, including mobile genetic elements. The term 
    ``intergeneric microorganism'' does not include a microorganism which 
    contains genetic material consisting of only well-characterized, non-
    coding regulatory regions from another genus.
        Introduced genetic material means genetic material that is added 
    to, and remains as a component of, the genome of the recipient.
        Manufacture, import, or process for commercial purposes means: (1) 
    To import, produce, manufacture, or process with the purpose of 
    obtaining an immediate or eventual commercial advantage for the 
    manufacturer, importer, or processor, and includes, among other things, 
    ``manufacture'' or ``processing'' of any amount of a microorganism or 
    microbial mixture:
        (i) For commercial distribution, including for test marketing.
        (ii) For use by the manufacturer, including use for product 
    research and development or as an intermediate.
        (2) The term also applies to substances that are produced 
    coincidentally during the manufacture, processing, use, or disposal of 
    another microorganism or microbial mixture, including byproducts that 
    are separated from that other microorganism or microbial mixture and 
    impurities that remain in that microorganism or microbial mixture. 
    Byproducts and impurities without separate commercial value are 
    nonetheless produced for the purpose of obtaining a commercial 
    advantage, since they are part of the manufacture or processing of a 
    microorganism for commercial purposes.
        Microbial commercial activity notice or MCAN means a notice for 
    microorganisms submitted to EPA pursuant to subpart D of this part.
        Microbial mixture means any combination of microorganisms or 
    microorganisms and other chemical substances, if the combination does 
    not occur in nature and is not an article.
        Microorganism means an organism classified in the kingdoms Monera 
    (or Procaryotae), Protista, Fungi, and the Chlorophyta and the 
    Rhodophyta of the Plantae, and a virus or virus-like particle.
        Mobile genetic element or MGE means an element of genetic material 
    that has the ability to move genetic material within and between 
    organisms. ``Mobile genetic elements'' include all plasmids, viruses, 
    transposons, insertion sequences, and other classes of elements with 
    these general properties.
        New microorganism means a microorganism not included on the TSCA 
    Inventory.
        Small quantities solely for research and development (or ``small 
    quantities solely for purposes of scientific experimentation or 
    analysis or research on, or analysis of, such substance or another 
    substance, including such research or analysis for development of a 
    product'') means quantities of a microorganism manufactured, imported, 
    or processed or proposed to be manufactured, imported, or processed 
    solely for research and development that meet the requirements of 
    Sec. 725.234.
        Structure means a building or vessel which effectively surrounds 
    and encloses the microorganism and includes features designed to 
    restrict the microorganism from leaving.
        Submission means any MCAN or exemption request submitted to EPA 
    under this part.
        Technically qualified individual means a person or persons (1) Who, 
    because of education, training, or experience, or a combination of 
    these factors, is capable of understanding the health and environmental 
    risks associated with the microorganism which is used under his or her 
    supervision, (2) who is responsible for enforcing appropriate methods 
    of conducting scientific experimentation, analysis, or microbiological 
    research to minimize such risks, and (3) who is responsible for the 
    safety assessments and clearances related to the procurement, storage, 
    use, and disposal of the microorganism as may be appropriate or 
    required within the scope of conducting a research and development 
    activity.
        TSCA Experimental Release Application or TERA means an exemption 
    request for a research and development activity, which is not eligible 
    for a full exemption from reporting under Sec. 725.232, 725.234, or 
    725.238 of this part, submitted to EPA in accordance with subpart E of 
    this part.
        Well-characterized, non-coding regulatory region means a segment of 
    genetic material for which:
        (1) The exact nucleotide base sequences of the regulatory region 
    and any inserted flanking nucleotides are known and documented.
        (2) The regulatory region and any inserted flanking nucleotides do 
    not code for protein, peptide, or functional ribonucleic acid 
    molecules.
        (3) The regulatory region solely controls the activity of other 
    regions that code for protein or peptide molecules or act as 
    recognition sites for the initiation of nucleic acid or protein 
    synthesis.
    
    
    Sec. 725.8   Coverage of this part.
    
        (a) Microorganisms subject to this part. Only microorganisms which 
    are manufactured, imported, or processed for commercial purposes, as 
    defined in Sec. 725.3 of this part, are subject to the requirements of 
    this part.
        (b) Microoganisms automatically included on the Inventory. 
    Microorganisms that are not intergeneric are automatically included on 
    the TSCA Inventory.
        (c) Microorganisms not subject to this part. The following 
    microorganisms are not subject to this part, either because they are 
    not subject to TSCA jurisdiction or are not subject to reporting under 
    TSCA section 5.
        (1) Any microorganism which would be excluded from the definition 
    of ``chemical substance'' in section 3 of TSCA and Sec. 720.3(e) of 
    this chapter.
        (2) Any microbial mixture as defined in Sec. 725.3 of this part. 
    This exclusion applies only to a microbial mixture as a whole and not 
    to any microorganisms and other chemical substances which are part of 
    the microbial mixture.
        (3) Any microorganism that is manufactured and processed solely for 
    export if the following conditions are met:
        (i) The microorganism is labeled in accordance with section 
    12(a)(1)(B) of TSCA, when the microorganism is distributed in commerce.
        (ii) The manufacturer and processor can document at the 
    commencement of manufacturing or processing that the person to whom the 
    microorganism will be distributed intends to export it or process it 
    solely for export as defined in Sec. 721.3 of this chapter.
    
    
    Sec. 725.12   Identification of microorganisms for Inventory and other 
    listing purposes.
    
        To identify and list microorganisms on the Inventory, both 
    taxonomic designations and supplemental information will be used. The 
    supplemental information required in paragraph (b) of this section will 
    be used to specifically describe an individual microorganism on the 
    Inventory. Submitters must provide the supplemental information 
    required by paragraph (b) of this section to the extent necessary to 
    enable a microorganism to be accurately and unambiguously identified on 
    the Inventory.
        (a) Taxonomic designation. The taxonomic designation of a 
    microorganism must be provided for the donor organism and the recipient 
    microorganism to the level of strain, as appropriate. These 
    designations must be substantiated by a letter from a culture 
    collection, literature references, or the results of tests conducted 
    for the purpose of taxonomic classification. Upon EPA's request to the 
    submitter, data supporting the taxonomic designation must be provided 
    to EPA. The genetic history of the recipient microorganism should be 
    documented back to the isolate from which it was derived.
        (b) Supplemental information. The supplemental information 
    described in paragraphs (b)(1) and (b)(2) of this section is required 
    to the extent that it enables a microorganism to be accurately and 
    unambiguously identified.
        (1) Phenotypic information. Phenotypic information means pertinent 
    traits that result from the interaction of a microorganism's genotype 
    and the environment in which it is intended to be used and may include 
    intentionally added biochemical and physiological traits.
        (2) Genotypic information. Genotypic information means the 
    pertinent and distinguishing genotypic characteristics of a 
    microorganism, such as the identity of the introduced genetic material 
    and the methods used to construct the reported microorganism. This also 
    may include information on the vector construct, the cellular location, 
    and the number of copies of the introduced genetic material.
    
    
    Sec. 725.15   Determining applicability when microorganism identity or 
    use is confidential or uncertain.
    
        (a) Consulting EPA. Persons intending to conduct activities 
    involving microorganisms may determine their obligations under this 
    part by consulting the TSCA Inventory or the microorganisms and uses 
    specified in Sec. 725.239 or subpart M of this part. This section 
    establishes procedures for EPA to assist persons in determining whether 
    the microorganism or the use is listed on the Inventory or in 
    Sec. 725.239 or subpart M of this part.
        (1) Confidential identity or use. In some cases it may not be 
    possible to directly determine if a specific microorganism is listed, 
    because portions of that entry may contain generic information to 
    protect confidential business information (CBI). If any portion of the 
    microorganism's identity or use has been claimed CBI, that portion does 
    not appear on the public version of the Inventory, in Sec. 725.239 or 
    in subpart M of this part. Instead, it is contained in a confidential 
    version held in EPA's Confidential Business Information Center (CBIC). 
    The public versions contain generic information which masks the 
    confidential business information. A person who intends to conduct an 
    activity involving a microorganism or use whose entry is described with 
    generic information will need to inquire of EPA whether the unreported 
    microorganism or use is on the confidential version.
        (2) Uncertain microorganism identity. The current state of 
    scientific knowledge leads to some imprecision in describing a 
    microorganism. As the state of knowledge increases, EPA will be 
    developing policies to determine whether one microorganism is 
    equivalent to another. Persons intending to conduct activities 
    involving microorganisms may inquire of EPA whether the microorganisms 
    they intend to manufacture, import, or process are equivalent to 
    specific microorganisms described on the Inventory, in Sec. 725.239 or 
    subpart M of this part.
        (b) Requirement of bona fide intent. (1) EPA will answer the 
    inquiries described in paragraph (a) of this section only if the Agency 
    determines that the person has a bona fide intent to conduct the 
    activity for which reporting is required or for which any exemption may 
    apply.
        (2) To establish a bona fide intent to manufacture, import, or 
    process a microorganism, the person who intends to manufacture, import, 
    or process the microorganism must submit the following information in 
    writing to the Office of Pollution Prevention and Toxics, Document 
    Control Officer, 7407, 401 M St., SW., Washington, DC 20460, ATTN: 
    BIOTECH bona fide submission.
        (i) Taxonomic designations and supplemental information required by 
    Sec. 725.12.
        (ii) A signed statement certifying that the submitter intends to 
    manufacture, import, or process a microorganism for commercial 
    purposes.
        (iii) A description of research and development activities 
    conducted with the microorganism to date, demonstration of the 
    submitter's ability to produce or obtain the microorganism from a 
    foreign manufacturer, and the purpose for which the person will 
    manufacture, import, or process the microorganism.
        (iv) An indication of whether a related microorganism was 
    previously reviewed by the Agency to the extent known by the submitter.
        (c) If an importer or processor cannot provide all the information 
    required by paragraph (b) of this section, because it is claimed as 
    confidential business information by its foreign manufacturer or 
    supplier, the foreign manufacturer or supplier may supply the 
    information directly to EPA.
        (d) EPA will review the information submitted by the manufacturer, 
    importer, or processor under this paragraph to determine whether that 
    person has shown a bona fide intent to manufacture, import, or process 
    the microorganism. If necessary, EPA will compare this information to 
    the information requested for the confidential microorganism under 
    Sec. 725.85(b)(3)(iii).
        (e) In order for EPA to make a conclusive determination of the 
    microorganism's status, the proposed manufacturer, importer, or 
    processor must show a bona fide intent to manufacture, import, or 
    process the microorganism and must provide sufficient information to 
    establish identity unambiguously. After sufficient information has been 
    provided, EPA will inform the manufacturer, importer, or processor 
    whether the microorganism is subject to this part and if so, which 
    sections of this part apply.
        (f) If the microorganism is found on the confidential version of 
    the Inventory, in Sec. 725.239 or subpart M of this part, EPA will 
    notify the person(s) who originally reported the microorganism that 
    another person (whose identity will remain confidential, if so 
    requested) has demonstrated a bona fide intent to manufacture, import, 
    or process the microorganism and therefore was told that the 
    microorganism is subject to this part.
        (g) A disclosure to a person with a bona fide intent to 
    manufacture, import, or process a particular microorganism that the 
    microorganism is subject to this part will not be considered a public 
    disclosure of confidential business information under section 14 of the 
    Act.
        (h) EPA will answer an inquiry on whether a particular 
    microorganism is subject to this part within 30 days after receipt of a 
    complete submission under paragraph (b) of this section.

    Sec. 725.20   Scope and purpose.
    
        This subpart describes general administrative procedures applicable 
    to all persons who submit MCANs and exemption requests to EPA under 
    section 5 of the Act for microorganisms.
    
    
    Sec. 725.25   General administrative requirements.
    
        (a) General. (1) Each person who is subject to the notification 
    provisions of this part must complete, sign, and submit a MCAN or 
    exemption request containing the information as required for the 
    appropriate submission under this part. Except as otherwise provided, 
    each submission must include all referenced attachments. All 
    information in the submission (unless certain attachments appear in the 
    open scientific literature) must be in English. All information 
    submitted must be true and correct.
        (2) In addition to specific information required, the submitter 
    should submit all information known to or reasonably ascertainable by 
    the submitter that would permit EPA to make a reasoned evaluation of 
    the human health and environmental effects of the microorganism and any 
    microbial mixture or article that may contain the microorganism.
        (b) Certification. Persons submitting MCANs and exemption requests 
    to EPA under this part, and material related to their reporting 
    obligations under this part, must attach the following statement to any 
    information submitted to EPA:
    
        I certify that to the best of my knowledge and belief: The 
    company named in this submission intends to manufacture, import, or 
    process for a commercial purpose, other than in small quantities 
    solely for research and development, the microorganism identified in 
    this submission. All information provided in this submission is 
    complete and truthful as of the date of submission. I am including 
    with this submission all test data in my possession or control and a 
    description of all other data known to or reasonably ascertainable 
    by me as required by 40 CFR 725.160 or 725.260.
    
    This statement must be signed and dated by an authorized official of 
    the submitter.
        (c) Where to submit information under this part. Persons submitting 
    MCANs and exemption requests to EPA under this part, and material 
    related to their reporting obligations under this part, must send them 
    to: TSCA Document Processing Center (7407), Rm. L-100, Office of 
    Pollution Prevention and Toxics, U.S. Environmental Protection Agency, 
    401 M St., SW., Washington, DC 20460.
        (d) General requirements for submission of data. (1) Submissions 
    under this part must include the information described in Sec. 725.155, 
    725.255, 725.355, or 725.455, as appropriate, to the extent such 
    information is known to or reasonably ascertainable by the submitter.
        (2) In accordance with Sec. 725.160 or 725.260, as appropriate, the 
    submission must also include any test data in the submitter's 
    possession or control and descriptions of other data which are known to 
    or reasonably ascertainable by the submitter and which concern the 
    health and environmental effects of the microorganism.
        (e) Agency or joint submissions. (1) A manufacturer or importer may 
    designate an agent to submit the MCAN or exemption request. Both the 
    manufacturer or importer and the agent must sign the certification 
    required in paragraph (b) of this section.
        (2) A manufacturer or importer may authorize another person (e.g., 
    a foreign manufacturer or supplier, or a toll manufacturer) to report 
    some of the information required in theMCAN or exemption request to EPA 
    on its behalf. If separate portions of a joint submission are not 
    submitted together, the submitter must indicate which information will 
    be supplied by another person and identify that person. The 
    manufacturer or importer and any other person supplying the information 
    must sign the certification required by paragraph (b) of this section.
        (3) If EPA receives a submission which does not include the 
    information required, which the submitter indicates that it has 
    authorized another person to provide, the review period will not begin 
    until EPA receives all of the required information.
        (f) Microorganisms subject to a section 4 test rule. (1) Except as 
    provided in paragraph (f)(3) of this section, if (i) A person intends 
    to manufacture or import a new microorganism which is subject to the 
    notification requirements of this part, and (ii) the microorganism is 
    subject to a test rule promulgated under section 4 of the Act before 
    the notice is submitted, section 5(b)(1) of the Act requires the person 
    to submit the test data required by the testing rule with the notice. 
    The person must submit the data in the form and manner specified in the 
    test rule and in accordance with Sec. 725.160. If the person does not 
    submit the test data, the submission is incomplete and EPA will follow 
    the procedures in Sec. 725.33.
        (2) If EPA has granted the submitter an exemption under section 
    4(c) of the Act from the requirement to conduct tests and submit data, 
    the person may not file a MCAN or TERA until EPA receives the test 
    data.
        (3) If EPA has granted the submitter an exemption under section 
    4(c) of the Act and if another person previously has submitted the test 
    data to EPA, the exempted person may either submit the test data or 
    provide the following information as part of the notice:
        (i) The name, title, and address of the person who submitted the 
    test data to EPA.
        (ii) The date the test data were submitted to EPA.
        (iii) A citation for the test rule.
        (iv) A description of the exemption and a reference identifying it.
        (g) Microorganisms subject to a section 5(b)(4) rule. (1) If a 
    person (i) Intends to manufacture or import a microorganism which is 
    subject to the notification requirements of this part and which is 
    subject to a rule issued under section 5(b)(4) of the Act; and (ii) is 
    not required by a rule issued under section 4 of the Act to submit test 
    data for the microorganism before the filing of a submission, the 
    person must submit to EPA data described in paragraph (g)(2) of this 
    section at the time the submission is filed.
        (2) Data submitted under paragraph (g)(1) of this section must be 
    data which the person submitting the notice believes show that the 
    manufacture, processing, distribution in commerce, use, and disposal of 
    the microorganism, or any combination of such activities, will not 
    present an unreasonable risk of injury to health or the environment.
        (h) Data that need not be submitted. Specific data requirements are 
    listed in subparts D, E, F, G, and L of this part. The following is a 
    list of data that need not be submitted under this part:
        (1) Data previously submitted to EPA. (i) A person need not submit 
    any data previously submitted to EPA with no claims of confidentiality 
    if the new submission includes: the office or person to whom the data 
    were submitted; the date of submission; and, if appropriate, a standard 
    literature citation as specified in Sec. 725.160(a)(3)(ii).
        (ii) For data previously submitted to EPA with a claim of 
    confidentiality, the person must resubmit the data with the new 
    submission and any claim of confidentiality, under Sec. 725.80.
        (2) Efficacy data. This part does not require submission of any 
    data related solely to product efficacy. However, including efficacy 
    data will improve EPA's ability to assess the benefits of the use of 
    the microorganism. This does not exempt a person from submitting any of 
    the data specified in Sec. 725.160 or 725.260.
        (3) Non-U.S. exposure data. This part does not require submission 
    of any data which relates only to exposure of humans or the environment 
    outside the United States. This does not exclude nonexposure data such 
    as data on health effects (including epidemiological studies), 
    ecological effects, physical and chemical properties, or environmental 
    fate characteristics.
    
    
    Sec. 725.27   Submissions.
    
        Each person who is required to submit information under this part 
    must submit the information in the form and manner set forth in the 
    appropriate subpart.
        (a) Requirements specific to MCANs are described in 
    Sec. Sec. 725.150 through 725.160.
        (b) Requirements specific to TERAs are described in 
    Sec. Sec. 725.250 through 725.260.
        (c) Requirements specific to test marketing exemptions (TMEs) are 
    described in Sec. Sec. 725.350 and 725.355.
        (d) Requirements specific to Tier I and Tier II exemptions for 
    certain general commercial uses are described in Sec. Sec. 725.424 
    through 725.460.
        (e) Additional requirements specific to significant new uses for 
    microorganisms are described at Sec. 725.950.
    
    
    Sec. 725.28   Notice that submission is not required.
    
        When EPA receives a MCAN or exemption request, EPA will review it 
    to determine whether the microorganism is subject to the requirements 
    of this part. If EPA determines that the microorganism is not subject 
    to these requirements, EPA will notify the submitter that section 5 of 
    the Act does not prevent the manufacture, import, or processing of the 
    microorganism and that the submission is not needed.
    
    
    Sec. 725.29   EPA acknowledgement of receipt of submission.
    
        (a) EPA will acknowledge receipt of each submission by sending the 
    submitter a letter that identifies the number assigned to the new 
    microorganism and the date on which the review period begins. The 
    review period will begin on the date the MCAN or exemption request is 
    received by the Office of Pollution Prevention and Toxics Document 
    Control Officer.
        (b) The acknowledgement does not constitute a finding by EPA that 
    the submission is in compliance with this part.
    
    
    Sec. 725.32   Errors in the submission.
    
        (a) Within 30 days of receipt of the submission, EPA may request 
    that the submitter remedy errors in the submission. The following are 
    examples of such errors:
        (1) Failure to date the submission.
        (2) Typographical errors that cause data to be misleading or 
    answers to any questions to be unclear.
        (3) Contradictory information.
        (4) Ambiguous statements or information.
        (b) In the request to correct the submission, EPA will explain the 
    action which the submitter must take to correct the submission.
        (c) If the submitter fails to correct the submission within 15 days 
    of receipt of the request, EPA may extend the review period.
    
    
    Sec. 725.33   Incomplete submissions.
    
        (a) A submission under this part is not complete, and the review 
    period does not begin, if:
        (1) The wrong person files the submission.
        (2) The submitter does not attach and sign the certification 
    statement as required by Sec. 725.25(b).
        (3) Some or all of the information in the submission or any 
    attachments are not in English, except for published scientific

        (4) The submitter does not provide information that is required by 
    sections 5(d)(1)(B) and (C) of the Act and Sec. 725.160 or 725.260, as 
    appropriate.
        (5) The submitter does not provide information required by 
    Sec. 725.25, 725.155, 725.255, 725.355, or 725.455, as appropriate, or 
    indicate that it is not known to or reasonably ascertainable by the 
    submitter.
        (6) The submitter has asserted confidentiality claims and has 
    failed to:
        (i) Submit a second copy of the submission with all confidential 
    information deleted for the public file, as required by 
    Sec. 725.80(b)(2).
        (ii) Comply with the substantiation requirements as described in 
    Sec. 725.94.
        (7) The submitter does not include any information required by 
    section 5(b)(1) of the Act and pursuant to a rule promulgated under 
    section 4 of the Act, as required by Sec. 725.25(f).
        (8) The submitter does not submit data which the submitter believes 
    show that the microorganism will not present an unreasonable risk of 
    injury to health or the environment, if EPA has listed the 
    microorganism under section 5(b)(4) of the Act, as required in 
    Sec. 725.25(g).
        (9) For MCANs, the submitter does not remit the fees required by 
    Sec. 700.45(b)(1) or (b)(2)(vi) of this chapter.
        (b)(1) If EPA receives an incomplete submission under this part, 
    the Director, or a designee, will notify the submitter within 30 days 
    of receipt that the submission is incomplete and that the review period 
    will not begin until EPA receives a complete submission.
        (2) If EPA obtains additional information during the review period 
    for any submission that indicates the original submission was 
    incomplete, the Director, or a designee, may declare the submission 
    incomplete within 30 days after EPA obtains the additional information 
    and so notify the submitter.
        (c) The notification that a submission is incomplete under 
    paragraph (b) of this section will include:
        (1) A statement of the basis of EPA's determination that the 
    submission is incomplete.
        (2) The requirements for correcting the incomplete submission.
        (3) Information on procedures under paragraph (d) of this section 
    for filing objections to the determination or requesting modification 
    of the requirements for completing the submission.
        (d) Within 10 days after receipt of notification by EPA that a 
    submission is incomplete, the submitter may file written objections 
    requesting that EPA accept the submission as complete or modify the 
    requirements necessary to complete the submission.
        (e)(1) EPA will consider the objections filed by the submitter. The 
    Director, or a designee, will determine whether the submission was 
    complete or incomplete, or whether to modify the requirements for 
    completing the submission. EPA will notify the submitter in writing of 
    EPA's response within 10 days of receiving the objections.
        (2) If the Director, or a designee, determines, in response to the 
    objection, that the submission was complete, the review period will be 
    deemed suspended on the date EPA declared the submission incomplete, 
    and will resume on the date that the submission is declared complete. 
    The submitter need not correct the submission as EPA originally 
    requested. If EPA can complete its review within the review period 
    beginning on the date of the submission, the Director, or a designee, 
    may inform the submitter that the running of the review period will 
    resume on the date EPA originally declared it incomplete.
        (3) If the Director, or a designee, modifies the requirements for 
    completing the submission or concurs with EPA's original determination, 
    the review period will begin when EPA receives a complete submission.
        (f) Materially false or misleading statements. If EPA discovers at 
    any time that a person submitted materially false or misleading 
    statements in information submitted under this part, EPA may find that 
    the submission was incomplete from the date it was submitted, and take 
    any other appropriate action.
    
    
    Sec. 725.36   New information.
    
        (a) During the review period, if a submitter possesses, controls, 
    or knows of new information that materially adds to, changes, or 
    otherwise makes significantly more complete the information included in 
    the MCAN or exemption request, the submitter must send that information 
    to the address listed in Sec. 725.25(c) within 10 days of receiving the 
    new information, but no later than 5 days before the end of the review 
    period.
        (b) The new submission must clearly identify the submitter, the 
    MCAN or exemption request to which the new information is related, and 
    the number assigned to that submission by EPA, if known to the 
    submitter.
        (c) If the new information becomes available during the last 5 days 
    of the review period, the submitter must immediately inform the EPA 
    contact for that submission by telephone of the new information.
    
    
    Sec. 725.40   Notice in the Federal Register.
    
        (a) Filing of Federal Register notice. After EPA receives a MCAN or 
    an exemption request under this part, EPA will issue a notice in the 
    Federal Register including the information specified in paragraph (b) 
    of this section.
        (b) Contents of notice. (1) In the public interest, the specific 
    microorganism identity listed in the submission will be published in 
    the Federal Register unless the submitter has claimed the microorganism 
    identity confidential. If the submitter claims confidentiality, a 
    generic name will be published in accordance with Sec. 725.85.
        (2) The categories of use of the microorganism will be published as 
    reported in the submission unless this information is claimed 
    confidential. If confidentiality is claimed, the generic information 
    which is submitted under Sec. 725.88 will be published.
        (3) A list of information submitted in accordance with 
    Sec. 725.160(a), 725.255, 725.260, 725.355, or 725.455, as appropriate, 
    will be published.
        (4) The submitter's identity will be published, unless the 
    submitter has claimed it confidential.
        (c) Publication of exemption decisions. Following the expiration of 
    the appropriate review period for the exemption request, EPA will issue 
    a notice in the Federal Register indicating whether the request has 
    been approved or denied and the reasons for the decision.
    
    
    Sec. 725.50   EPA review.
    
         (a) MCANs. The review period specified in section 5(a) of the Act 
    for MCANs runs for 90 days from the date the Document Control Officer 
    receives a complete submission, or the date EPA determines the 
    submission is complete under Sec. 725.33, unless the Agency extends the 
    review period under section 5(c) of TSCA and Sec. 725.56.
        (b) Exemption requests. The review period starts on the date the 
    Document Control Officer receives a complete exemption request, or the 
    date EPA determines the request is complete under Sec. 725.33, unless 
    the Agency extends the review period under Sec. 725.56. The review 
    periods for exemption requests run as follows:
        (1) TERAs. The review period for TERAs is 60 days.
        (2) TMEs. The review period for TMEs is 45 days.
        (3) Tier II exemption requests. The review period for Tier II 
    exemption requests is 45 days.
    
    
    Sec. 725.54   Suspension of the review period.
    
        (a) A submitter may voluntarily suspend the running of the review 
    period if the Director, or a designee, agrees. If the Director does not 
    agree, the review period will continue to run, and EPA will notify the 
    submitter. A submitter may request a suspension at any time during the 
    review period. The suspension must be for a specified period of time.
        (b) A request for suspension may be made in writing to the address 
    listed in Sec. 725.25(c). The suspension also may be made orally, 
    including by telephone, to the submitter's EPA contact for that 
    submission. EPA will send the submitter a written confirmation that the 
    suspension has been granted.
        (1) An oral request may be granted for no longer than 15 days. To 
    obtain a longer suspension, the Document Control Officer for the Office 
    of Pollution Prevention and Toxics must receive written confirmation of 
    the oral request. The review period is suspended as of the date of the 
    oral request.
        (2) If the submitter has not made a previous oral request, the 
    running of the review period is suspended as of the date of receipt of 
    the written request by the Document Control Officer for the Office of 
    Pollution Prevention and Toxics.
    
    
    Sec. 725.56   Extension of the review period.
    
        (a) At any time during the review period, EPA may unilaterally 
    determine that good cause exists to extend the review period specified 
    for MCANs, or the exemption requests.
        (b) If EPA makes such a determination, EPA:
        (1) Will notify the submitter that EPA is extending the review 
    period for a specified length of time and state the reasons for the 
    extension.
        (2) For MCANS, may issue a notice for publication in the Federal 
    Register which states that EPA is extending the review period and gives 
    the reasons for the extension.
        (c) The total period of the extension may be for a period of up to 
    the same length of time as specified for each type of submission in 
    Sec. 725.50. If the initial extension is for less than the total time 
    allowed, EPA may make additional extensions. However, the sum of the 
    extensions may not exceed the total allowed.
        (d) The following are examples of situations in which EPA may find 
    that good cause exists for extending the review period:
        (1) EPA has reviewed the submission and is seeking additional 
    information.
        (2) EPA has received significant additional information during the 
    review period.
        (3) The submitter has failed to correct a submission after 
    receiving EPA's request under Sec. 725.32.
        (4) EPA has reviewed the submission and determined that there is a 
    significant possibility that the microorganism will be regulated under 
    section 5(e) or section 5(f) of the Act, but EPA is unable to initiate 
    regulatory action within the initial review period.
    
    
    Sec. 725.60   Withdrawal of submission by the submitter.
    
        (a) A submitter may withdraw a submission during the review period. 
    A statement of withdrawal must be made in writing to the address listed 
    in Sec. 725.25(c). The withdrawal is effective upon receipt of the 
    statement by the Document Control Officer.
        (b) If a manufacturer or importer who withdrew a submission later 
    resubmits a submission for the same microorganism, a new review period 
    begins.
    
    
    Sec. 725.65   Recordkeeping.
    
        (a) General provisions. (1) Any person who files under this part 
    must retain documentation of information in the submission, including

    part.
    
    
    Sec. 725.67   Applications to exempt new microorganisms from this part.
    
        (a) Submission. (1) Any manufacturer or importer of a new 
    microorganism may request, under TSCA section 5(h)(4), an exemption, in 
    whole or in part, from this part by sending a Letter of Application to 
    the Director, Chemical Control Division, Office of Pollution Prevention 
    and Toxics, U.S. Environmental Protection Agency, 401 M St., SW., 
    Washington, DC 20460.
        (2) The Letter of Application should provide information to show 
    that any activities affected by the requested exemption will not 
    present an unreasonable risk of injury to health or the environment. 
    This information should include data described in the following 
    paragraphs.
        (i) The effects of the new microorganism on health and the 
    environment.
        (ii) The magnitude of exposure of human beings and the environment 
    to the new microorganism.
        (iii) The benefits of the new microorganism for various uses and 
    the availability of substitutes for such uses.
         (iv) The reasonably ascertainable economic consequences of 
    granting or denying the exemption, including effects on the national 
    economy, small business, and technological innovation.
         (b) Processing of the Letter of Application by EPA--(1) Grant of 
    the Application. If, after consideration of the Letter of Application 
    and any other relevant information available to the Agency, the 
    Assistant Administrator for Prevention, Pesticides and Toxic Substances 
    makes a preliminary determination that the new microorganism will not 
    present an unreasonable risk of injury to health or the environment, 
    the Assistant Administrator will propose a rule to grant the exemption 
    using the applicable procedures in part 750 of this chapter.
        (2) Denial of the application. If the Assistant Administrator 
    decides that the preliminary determination described in paragraph 
    (b)(1) of this section cannot be made, the application will be denied 
    by sending the applicant a written statement with the Assistant 
    Administrator's reasons for denial.
        (c) Processing of the exemption--(1) Unreasonable risk standard. 
    Granting a TSCA section 5(h)(4) exemption requires a determination that 
    there will be no unreasonable risk.
        (i) An unreasonable risk determination under TSCA is an 
    administrative judgment that requires balancing of the harm to health 
    or the environment that a chemical substance may cause and the 
    magnitude and severity of that harm, against the social and economic 
    effects on society of Agency action to reduce that harm.
        (ii) A determination of unreasonable risk under TSCA section 
    5(h)(4) will examine the reasonably ascertainable economic and social 
    consequences of granting or denying the exemption after consideration 
    of the effect on the national economy, small business, technological 
    innovation, the environment, and public health.
        (2) Grant of the exemption. The exemption will be granted if the 
    Assistant Administrator determines, after consideration of all relevant 
    evidence presented in the rulemaking proceeding described in paragraph 
    (b)(1) of this section, that the new microorganism will not present an 
    unreasonable risk of injury to health or the environment.
        (3) Denial of the exemption. The exemption will be denied if the 
    Assistant Administrator determines, after consideration of all relevant 
    evidence presented in the rulemaking proceeding described in paragraph 
    (b)(1) of this section, that the determination described in paragraph 
    (c)(2) of this section cannot be made. A final decision terminating the 
    rulemaking proceeding will be published in the Federal Register.
    
    
    Sec. 725.70   Compliance.
    
        (a) Failure to comply with any provision of this part is a 
    violation of section 15 of the Act (15 U.S.C. 2614).
        (b) A person who manufactures or imports a microorganism before a 
    MCAN is submitted and the MCAN review period expires is in violation of 
    section 15 of the Act even if that person was not required to submit 
    the MCAN under Sec. 725.105.
        (c) Using a microorganism which a person knew or had reason to know 
    was manufactured, processed, or distributed in commerce in violation of 
    section 5 of the Act or this part is a violation of section 15 of the 
    Act (15 U.S.C. 2614).
        (d) Failure or refusal to establish and maintain records or to 
    permit access to or copying of records, as required by the Act, is a 
    violation of section 15 of the Act (15 U.S.C. 2614).
        (e) Failure or refusal to permit entry or inspection as required by 
    section 11 of the Act is a violation of section 15 of the Act (15 
    U.S.C. 2614).
        (f) Violators may be subject to the civil and criminal penalties in 
    section 16 of the Act (15 U.S.C. 2615) for each violation. Persons who 
    submit materially misleading or false information in connection with 
    the requirements of any provision of this part may be subject to 
    penalties calculated as if they never filed their submissions.
        (g) EPA may seek to enjoin the manufacture or processing of a 
    microorganism in violation of this part or act to seize any 
    microorganism manufactured or processed in violation of this part or 
    take other actions under the authority of section 7 of the Act (15 
    U.S.C. 2606) or section 17 of the Act (15 U.S.C. 2616).
    
    
    Sec. 725.75   Inspections.
    
        EPA will conduct inspections under section 11 of the Act to assure 
    compliance with section 5 of the Act and this part, to verify that 
    information required by EPA under this part is true and correct, and to 
    audit data submitted to EPA under this part.
    Subpart C--Confidentiality and Public Access to Information
    
    
    Sec. 725.80  General provisions for confidentiality claims.
    
        (a) A person may assert a claim of confidentiality for any 
    information submitted to EPA under this part.
        (1) Any person who asserts a claim of confidentiality for portions 
    of the specific microorganism identity must provide the information as 
    described in Sec. 725.85.
        (2) Any person who asserts a claim of confidentiality for a use of 
    a microorganism must provide the information as described in 
    Sec. 725.88.
        (3) Any person who asserts a claim of confidentiality for 
    information contained in a health and safety study of a microorganism 
    must provide the information described in Sec. 725.92.
        (b) Any claim of confidentiality must accompany the information 
    when it is submitted to EPA.
        (1) When a person submits any information under this part, 
    including any attachments, the claim(s) must be asserted by circling 
    the specific information which is claimed as confidential and marking 
    the page on which that information appears with an appropriate 
    designation such as ``trade secret,'' ``TSCA CBI,'' or ``confidential 
    business information.''
        (2) If any information is claimed confidential, the person must 
    submit two copies of the information.
        (i) One copy of the information must be complete. In that copy, the 
    submitter must mark the information which is claimed as confidential in 
    the manner prescribed in paragraph (b)(1) of this section.
        (ii) The second copy must be complete except that all information 
    claimed as confidential in the first copy must be deleted. EPA will 
    place the second copy in the public file.
        (iii) If the submitter does not provide the second copy, the 
    submission is incomplete and the review period does not begin to run 
    until EPA receives the second copy, in accordance with Sec. 725.33.
        (iv) Any information contained within the copy submitted under 
    paragraph (b)(2)(ii) of this section which has been in the public file 
    for more than 30 days will be presumed to be in the public domain, 
    notwithstanding any assertion of confidentiality made under this 
    section.
        (c) Any person asserting a claim of confidentiality under this part 
    must substantiate each claim in accordance with the requirements in 
    Sec. 725.94.
        (d) EPA will disclose information that is subject to a claim of 
    confidentiality asserted under this section only to the extent 
    permitted by the Act, this subpart, and part 2 of this title.
        (e) If a submitter does not assert a claim of confidentiality for 
    information at the time it is submitted to EPA, EPA may make the 
    information public and place it in the public file without further 
    notice to the submitter.
    
    
    Sec. 725.85  Microorganism identity.
    
        (a) Claims applicable to the period prior to commencement of 
    manufacture or import for general commercial use--(1) When to make a 
    claim. (i) A person who submits information to EPA under this part may 
    assert a claim of confidentiality for portions of the specific 
    microorganism identity at the time of submission of the information. 
    This claim will apply only to the period prior to the commencement of 
    manufacture or import for general commercial use.
        (ii) A person who submits information to EPA under this part must 
    reassert a claim of confidentiality and substantiate the claim each 
    time the information is submitted to EPA. If a person claims certain 
    information confidential in a TERA submission and wishes the same 
    information to remain confidential in a subsequent TERA or MCAN 
    submission, the person must reassert and resubstantiate the claim in 
    the subsequent submission.
        (2) Assertion of claim. (i) A submitter may assert a claim of 
    confidentiality only if the submitter believes that public disclosure 
    prior to commencement of manufacture or import for general commercial 
    use of the fact that anyone is initiating research and development 
    activities pertaining to the specific microorganism or intends to 
    manufacture or import the specific microorganism for general commercial 
    use would reveal confidential business information. Claims must be 
    substantiated in accordance with the requirements of Sec. 725.94(a).
        (ii) If the submission includes a health and safety study 
    concerning the microorganism and if the claim for confidentiality with 
    respect to the specific identity is denied in accordance with 
    Sec. 725.92(c), EPA will deny a claim asserted under paragraph (a) of 
    this section.
        (3) Development of generic name. Any person who asserts a claim of 
    confidentiality for portions of the specific microorganism identity 
    under this paragraph must provide one of the following items at the 
    time the submission is filed:
        (i) The generic name which was accepted by EPA in the prenotice 
    consultation conducted under paragraph (a)(4) of this section.
        (ii) One generic name that is only as generic as necessary to 
    protect the confidential identity of the particular microorganism. The 
    name should reveal the specific identity to the maximum extent 
    possible. The generic name will be subject to EPA review and approval.
        (4) Determination by EPA. (i) Any person who intends to assert a 
    claim of confidentiality for the specific identity of a new 
    microorganism may seek a determination by EPA of an appropriate generic 
    name for the microorganism before filing a submission. For this 
    purpose, the person should submit to EPA:
        (A) The specific identity of the microorganism.
        (B) A proposed generic name(s) which is only as generic as 
    necessary to protect the confidential identity of the new 
    microorganism. The name(s) should reveal the specific identity of the 
    microorganism to the maximum extent possible.
        (ii) Within 30 days, EPA will inform the submitter either that one 
    of the proposed generic names is adequate or that none is adequate and 
    further consultation is necessary.
        (5) Use of generic name. If a submitter claims microorganism 
    identity as confidential under paragraph (a) of this section, and if 
    the submitter complies with paragraph (a)(2) of this section, EPA will 
    issue for publication in the Federal Register notice described in 
    Sec. 725.40 the generic name proposed by the submitter or one agreed 
    upon by EPA and the submitter.
        (b) Claims applicable to the period after commencement of 
    manufacture or import for general commercial use--(1) Maintaining 
    claim. Any claim of confidentiality under paragraph (a) of this section 
    is applicable only until the microorganism is manufactured or imported 
    for general commercial use and becomes eligible for inclusion on the 
    Inventory. To maintain the confidential status of the microorganism 
    identity when the microorganism is added to the Inventory, a submitter 
    must reassert the confidentiality claim and substantiate the claim in 
    the notice of commencement of manufacture required under Sec. 725.190.
        (i) A submitter may not claim the microorganism identity 
    confidential for the period after commencement of manufacture or import 
    for general commercial use unless the submitter claimed the 
    microorganism identity confidential under paragraph (a) of this section 
    in the MCAN submitted for the microorganism.
        (ii) A submitter may claim the microorganism identity confidential 
    for the period after commencement of manufacture or import for general 
    commercial use if the submitter did not claim the microorganism 
    identity confidential under paragraph (a) of this section in any TERA 
    submitted for the microorganism, but subsequently did claim 
    microorganism identity confidential in the MCAN submitted for the 
    microorganism.
        (2) Assertion of claim. (i) A person who believes that public 
    disclosure of the fact that anyone manufactures or imports the 
    microorganism for general commercial use would reveal confidential 
    business information may assert a claim of confidentiality under 
    paragraph (b) of this section.
        (ii) If the notice includes a health and safety study concerning 
    the new microorganism, and if the claim for confidentiality with 
    respect to the microorganism identity is denied in accordance with 
    Sec. 725.92(c), EPA will deny a claim asserted under paragraph (b) of 
    this section.
        (3) Requirements for assertion. Any person who asserts a 
    confidentiality claim for microorganism identity must:
        (i) Comply with the requirements of paragraph (a)(3) of this 
    section regarding submission of a generic name.
        (ii) Agree that EPA may disclose to a person with a bona fide 
    intent to manufacture or import the microorganism the fact that the 
    particular microorganism is included on the confidential Inventory for 
    purposes of notification under section 5(a)(1)(A) of the Act.
        (iii) Have available and agree to furnish to EPA upon request the 
    taxonomic designations and supplemental information required by 
    Sec. 725.12.
        (iv) Provide a detailed written substantiation of the claim, in 
    accordance with the requirements of Sec. 725.94(b).
        (4) Denial of claim. If the submitter does not meet the 
    requirements of paragraph (b) of this section, EPA will deny the claim 
    of confidentiality.
        (5) Acceptance of claim. (i) EPA will publish a generic name on the 
    public Inventory if:
        (A) The submitter asserts a claim of confidentiality in accordance 
    with this paragraph.
        (B) No claim for confidentiality of the microorganism identity as 
    part of a health and safety study has been denied in accordance with 
    part 2 of this title or Sec. 725.92.
        (ii) Publication of a generic name on the public Inventory does not 
    create a category for purposes of the Inventory. Any person who has a 
    bona fide intent to manufacture or import a microorganism which is 
    described by a generic name on the public Inventory may submit an 
    inquiry to EPA under Sec. 725.15(b) to determine whether the particular 
    microorganism is included on the confidential Inventory.
        (iii) Upon receipt of a request described in Sec. 725.15(b), EPA 
    may require the submitter who originally asserted confidentiality for a 
    microorganism to submit to EPA the information listed in paragraph 
    (b)(3)(iii) of this section.
        (iv) Failure to submit any of the information required under 
    paragraph (b)(3)(iii) of this section within 10 calendar days of 
    receipt of a request by EPA under paragraph (b) of this section will 
    constitute a waiver of the original submitter's confidentiality claim. 
    In this event, EPA may place the specific microorganism identity on the 
    public Inventory without further notice to the original submitter.
        (6) Use of generic name on the public Inventory. If a submitter 
    asserts a claim of confidentiality under paragraph (b) of this section, 
    EPA will examine the generic microorganism name proposed by the 
    submitter.
        (i) If EPA determines that the generic name proposed by the 
    submitter is only as generic as necessary to protect the confidential 
    identity of the particular microorganism, EPA will place that generic 
    name on the public Inventory.
        (ii) If EPA determines that the generic name proposed by the 
    submitter is more generic than necessary to protect the confidential 
    identity, EPA will propose in writing, for review by the submitter, an 
    alternative generic name that will reveal the identity of the 
    microorganism to the maximum extent possible.
        (iii) If the generic name proposed by EPA is acceptable to the 
    submitter, EPA will place that generic name on the public Inventory.
        (iv) If the generic name proposed by EPA is not acceptable to the 
    submitter, the submitter must explain in detail why disclosure of that 
    generic name would reveal confidential business information and propose 
    another generic name which is only as generic as necessary to protect 
    the confidential identity of the microorganism. If EPA does not receive 
    a response from the submitter within 30 days after the submitter 
    receives the proposed name, EPA will place EPA's chosen generic name on 
    the public Inventory. If the submitter does provide the information 
    requested, EPA will review the response. If the submitter's proposed 
    generic name is acceptable, EPA will publish that generic name on the 
    public Inventory. If the submitter's proposed generic name is not 
    acceptable, EPA will notify the submitter of EPA's choice of a generic 
    name. Thirty days after this notification, EPA will place the chosen 
    generic name on the public Inventory.
    
    
    Sec. 725.88   Uses of a microorganism.
    
        (a) Assertion of claim. A person who submits information to EPA 
    under this part on the categories or proposed categories of use of a 
    microorganism may assert a claim of confidentiality for this 
    information.
        (b) Requirements for claim. A submitter that asserts such a claim 
    must:
        (1) Report the categories or proposed categories of use of the 
    microorganism.
        (2) Provide, in nonconfidential form, a description of the uses 
    that is only as generic as necessary to protect the confidential 
    business information. The generic use description will be included in 
    the Federal Register notice described in Sec. 725.40.
        (c) Generic use description. The person must submit the information 
    required by paragraph (b) of this section by describing the uses as 
    precisely as possible, without revealing the information which is 
    claimed confidential, to disclose as much as possible how the use may 
    result in human exposure to the microorganism or its release to the 
    environment.
    
    
    Sec. 725.92   Data from health and safety studies of microorganisms.
    
        (a) Information other than specific microorganism identity. Except 
    as provided in paragraph (b) of this section, EPA will deny any claim 
    of confidentiality with respect to information included in a health and 
    safety study of a microorganism, unless the information would disclose 
    confidential business information concerning:
        (1) Processes used in the manufacture or processing of a 
    microorganism.
        (2) Information which is not in any way related to the effects of a 
    microorganism on human health or the environment, such as, the name of 
    the submitting company, cost or other financial data, product 
    development or marketing plans, and advertising plans, for which the 
    person submits a claim of confidentiality in accordance with 
    Sec. 725.80.
        (b) Microorganism identity--(1) Claims applicable to the period 
    prior to commencement of manufacture or import for general commercial 
    use. A claim of confidentiality for the period prior to commencement of 
    manufacture or import for general commercial use for the specific 
    identity of a microorganism for which a health and safety study was 
    submitted must be asserted in conjunction with a claim asserted under 
    Sec. 725.85(a). The submitter must substantiate each claim in 
    accordance with the requirements of Sec. 725.94(a).
        (2) Claims applicable to the period after commencement of 
    manufacture or import for general commercial use. To maintain the 
    confidential status of the specific identity of a microorganism for 
    which a health and safety study was submitted after commencement of 
    manufacture or import for general commercial use, the claim must be 
    reasserted and substantiated in conjunction with a claim under 
    Sec. 725.85(b). The submitter must substantiate each claim in 
    accordance with the requirements of Sec. 725.94(b).
        (c) Denial of confidentiality claim. EPA will deny a claim of 
    confidentiality for microorganism identity under paragraph (b) of this 
    section, unless:
        (1) The information would disclose processes used in the 
    manufacture or processing of a microorganism.
        (2) The microorganism identity is not necessary to interpret a 
    health and safety study.
        (d) Use of generic names. When EPA discloses a health and safety 
    study containing a microorganism identity, which the submitter has 
    claimed confidential, and if the Agency has not denied the claim under 
    paragraph (c) of this section, EPA will identify the microorganism by 
    the generic name selected under Sec. 725.85.
    
    
    Sec. 725.94   Substantiation requirements.
    
        (a) Claims applicable to the period prior to commencement of 
    manufacture or import for general commercial use--(1) MCAN, TME, Tier I 
    certification, and Tier II exemption request requirements. Any person 
    who submits a MCAN, TME, Tier I certification, or Tier II exemption 
    request should strictly limit confidentiality claims to that 
    information which is confidential and proprietary to the business.
        (i) If any information in the submission is claimed as confidential 
    business information, the submitter must substantiate each claim by 
    submitting written answers to the questions in paragraphs (c), (d), and 
    (e) of this section at the time the person submits the information.
        (ii) If the submitter does not provide written substantiation as 
    required in paragraph (a)(1)(i) of this section, the submission will be 
    considered incomplete and the review period will not begin in 
    accordance with Sec. 725.33.
        (2) TERA requirements. Any person who submits a TERA, should 
    strictly limit confidentiality claims to that information which is 
    confidential and proprietary to the business.
        (i) If any information in such a submission is claimed as 
    confidential business information, the submitter must substantiate each 
    of those claims by submitting written answers to the questions in 
    paragraphs (d) and (e) of this section at the time the person submits 
    the information.
        (ii) If the submitter does not provide written substantiation as 
    required in paragraph (a)(2)(i) of this section, the submission will be 
    considered incomplete and the TERA review period will not begin.
        (b) Claims applicable to the period after commencement of 
    manufacture or import for general commercial use. (1) If a submitter 
    claimed portions of the microorganism identity confidential in the MCAN 
    and wants the identity to be listed on the confidential Inventory, the 
    claim must be reasserted and substantiated at the time the Notice of 
    Commencement (NOC) is submitted. Otherwise, EPA will list the specific 
    microorganism identity on the public Inventory.
        (2) The submitter must substantiate the claim for confidentiality 
    of the microorganism identity by answering all of the questions in 
    paragraphs (c), (d), and (e) in this section. In addition, the 
    following questions must be answered:
        (i) What harmful effects to the company or institution's 
    competitive position, if any, would result if EPA publishes on the 
    Inventory the identity of the microorganism? How could a competitor use 
    such information given the fact that the identity of the microorganism 
    otherwise would appear on the TSCA Inventory with no link between the 
    microorganism and the company or industry? How substantial would the 
    harmful effects of disclosure be? What is the causal relationship 
    between the disclosure and the harmful effects?
        (ii) Has the identity of the microorganism been kept confidential 
    to the extent that competitors do not know it is being manufactured or 
    imported for general commercial use by anyone?
        (c) General questions. The following questions must be answered in 
    detail for each confidentiality claim:
        (1) For what period of time is a claim of confidentiality being 
    asserted? If the claim is to extend until a certain event or point in 
    time, indicate that event or time period. Explain why the information 
    should remain confidential until such point.
        (2) Briefly describe any physical or procedural restrictions within 
    the company or institution relating to the use and storage of the 
    information claimed as confidential. What other steps, if any, apply to 
    use or further disclosure of the information?
        (3) Has the information claimed as confidential been disclosed to 
    individuals outside of the company or institution? Will it be disclosed 
    to such persons in the future? If so, what restrictions, if any, apply 
    to use or further disclosure of the information?
        (4) Does the information claimed as confidential appear, or is it 
    referred to, in any of the following:
        (i) Advertising or promotional materials for the microorganism or 
    the resulting end product.
        (ii) Material safety data sheets or other similar materials for the 
    microorganism or the resulting end product.
        (iii) Professional or trade publications.
        (iv) Any other media available to the public or to your 
    competitors.
        (v) Patents.
        (vi) Local, State, or Federal agency public files.
    If the answer is yes to any of these questions, indicate where the 
    information appears and explain why it should nonetheless be treated as 
    confidential.
        (5) Has EPA, another Federal agency, a Federal court, or a State 
    made any confidentiality determination regarding the information 
    claimed as confidential? If so, provide copies of such determinations.
        (6) For each type of information claimed confidential, describe the 
    harm to the company or institution's competitive position that would 
    result if this information were disclosed. Why would this harm be 
    substantial? How could a competitor use such information? What is the 
    causal connection between the disclosure and harm?
        (7) If EPA disclosed to the public the information claimed as 
    confidential, how difficult would it be for the competitor to enter the 
    market for the resulting product? Consider such constraints as capital 
    and marketing cost, specialized technical expertise, or unusual 
    processes.
        (d) Microorganism identity and production method. If 
    confidentiality claims are asserted for the identity of the 
    microorganism or information on how the microorganism is produced, the 
    following questions must be answered:
        (1) Has the microorganism or method of production been patented in 
    the U.S. or elsewhere? If so, why is confidentiality necessary?
        (2) Does the microorganism leave the site of production or testing 
    in a form which is accessible to the public or to competitors? What is 
    the cost to a competitor, in time and money, to develop appropriate use 
    conditions? What factors facilitate or impede product analysis?
        (3) For each additional type of information claimed as 
    confidential, explain what harm would result from disclosure of each 
    type of information if the identity of the microorganism were to remain 
    confidential.
        (e) Health and safety studies of microorganisms. If confidentiality 
    claims are asserted for information in a health or safety study of a 
    microorganism, the following questions must be answered:
        (1) Would the disclosure of the information claimed confidential 
    reveal: (i) Confidential process information, or (ii) information 
    unrelated to the effects of the microorganism on human health and the 
    environment. Describe the causal connection between the disclosure and 
    harm.
        (2) Does the company or institution assert that disclosure of the 
    microorganism identity is not necessary to interpret any health and 
    safety studies which have been submitted? If so, explain how a less 
    specific identity would be sufficient to interpret the studies.
    
    
    Sec. 725.95   Public file.
    
        All information submitted, including any health and safety study of 
    a microorganism and other supporting documentation, will become part of 
    the public file for that submission, unless such materials are claimed 
    confidential. In addition, EPA may add materials to the public file, 
    unless such materials are claimed confidential. Any of the 
    nonconfidential material described in this subpart will be available 
    for public inspection in the TSCA Public Docket Office, Rm. NE-B607, 
    401 M St., SW., Washington, DC, between the hours of 8 a.m. and noon 
    and 1 p.m. to 4 p.m., Monday through Friday, excluding legal holidays.
    Subpart D--Microbial Commercial Activities Notification Requirements
    
    
    Sec. 725.100   Scope and purpose.
    
        (a) This subpart establishes procedures for submission of a notice 
    to EPA under section 5(a) of TSCA for persons who manufacture, import, 
    or process microorganisms for commercial purposes. This notice is 
    called a Microbial Commercial Activity Notice (MCAN). It is expected 
    that MCANs will in general only be submitted for microorganisms 
    intended for general commercial use.
        (b) Persons subject to MCAN submission are described in 
    Sec. 725.105.
        (c) Exclusions and exemptions specific to MCAN submissions are 
    described in Sec. 725.110.

    a new microorganism and (i) The manufacturer produces or processes the 
    microorganism exclusively for that person, and (ii) that person 
    specifies the identity of the microorganism, and controls the total 
    amount produced and the basic technology for the plant process, then 
    that person must submit the MCAN. If it is unclear who must report, EPA 
    should be contacted to determine who must submit the MCAN.
        (3) Only manufacturers that are incorporated, licensed, or doing 
    business in the United States may submit a MCAN.
        (b) Importers of new microorganisms. (1) MCAN submission is 
    required for a person who intends to import into the United States for 
    general commercial use a new microorganism. Exclusions are described in 
    Sec. 725.110.
        (2) When several persons are involved in an import transaction, the 
    MCAN must be submitted by the principal importer. If no one person fits 
    the principal importer definition in a particular transaction, the 
    importer should contact EPA to determine who must submit the MCAN for 
    that transaction.
        (3) Except as otherwise provided in paragraph (b)(4) of this 
    section, the provisions of this subpart D apply to each person who 
    submits a MCAN for a new microorganism which such person intends to 
    import for a general commercial use. In addition, each importer must 
    comply with paragraph (b)(4) of this section.
        (4) EPA will hold the principal importer, or the importer that EPA 
    determines must submit the MCAN when there is no principal importer 
    under paragraph (b)(2) of this section, liable for complying with this 
    part, for completing the MCAN, and for the completeness and 
    truthfulness of all information which it submits.
        (c) Manufacturers, importers, or processors of microorganisms who 
    intend to use or distribute the microorganism for a significant new 
    use. MCAN submission is required for any person who intends to 
    manufacture, import, or process for commercial purposes a microorganism 
    identified as having one or more significant new uses in subpart M of 
    this part, and who intends either to engage in a significant new use of 
    the microorganism or intends to distribute it in commerce. Persons 
    excluded from reporting on significant new uses of microorganisms and 
    additional procedures for reporting are described in subpart L of this 
    part.

    Sec. 725.170   EPA review of the MCAN.
    
        General procedures for review of all submissions under this part 
    are contained in Sec. Sec. 725.28 through 725.60. In addition, the 
    following procedures apply to EPA review of MCANs submitted under this 
    subpart:
        (a) Length of the review period. The MCAN review period specified 
    in section 5(a) of the Act runs for 90 days from the date the Document 
    Control Officer for the Office of Pollution Prevention and Toxics 
    receives a complete MCAN, or the date EPA determines the MCAN is 
    complete under Sec. 725.33, unless the Agency extends the period under 
    section 5(c) of the Act and Sec. 725.56.
        (b) Notice of expiration of MCAN review period. (1) EPA will notify 
    the submitter that the MCAN review period has expired or that EPA has 
    completed its review of the MCAN. Expiration of the review period does 
    not constitute EPA approval or certification of the new microorganism, 
    and does not mean that EPA may not take regulatory action against the 
    microorganism in the future.
        (2) After expiration of the MCAN review period, in the absence of 
    regulatory action by EPA under section 5(e), 5(f), or 6(a) of the Act, 
    the submitter may manufacture or import the microorganism even if the 
    submitter has not received notice of expiration.
        (3) Early notification that EPA has completed its review does not 
    permit commencement of manufacture or import prior to the expiration of 
    the 90-day MCAN review period.
        (c) Any person submitting a MCAN in response to the requirements of 
    this subpart shall not manufacture, import, or process a microorganism

        (e) The manufacturer, importer, or processor notifies all persons 
    in its employ or to whom it directly distributes the microorganism, who 
    are engaged in experimentation, research, or analysis on the 
    microorganism, including the manufacture, processing, use, transport, 
    storage, and disposal of the microorganism associated with research and 
    development activities, of any risk to health, identified under 
    Sec. 725.235(a), which may be associated with the microorganism. The 
    notification must be made in accordance with Sec. 725.235(b).
    
    
    Sec. 725.235   Conditions of exemption for activities conducted inside 
    a structure.
    
        (a) Determination of risks. (1) To determine whether notification 
    under Sec. 725.234(e) is required, the manufacturer, importer, or 
    processor must review and evaluate the following information to 
    determine whether there is reason to believe there is any risk to 
    health which may be associated with the microorganism:
        (i) Information in its possession or control concerning any 
    significant adverse reaction of persons exposed to the microorganism 
    which may reasonably be associated with such exposure.
        (ii) Information provided to the manufacturer, importer, or 
    processor by a supplier or any other person concerning a health risk 
    believed to be associated with the microorganism.
        (iii) Health and environmental effects data in its possession or 
    control concerning the microorganism.
        (iv) Information on health effects which accompanies any EPA rule 
    or order issued under section 4, 5, or 6 of the Act that applies to the 
    microorganism and of which the manufacturer, importer, or processor has 
    knowledge.
        (2) When the research and development activity is conducted solely 
    inside a laboratory and exposure to the microorganism is controlled 
    through the implementation of prudent practices for handling 
    microorganisms of unknown human health or environmental effects and any 
    distribution, except for purposes of disposal, is to other such 
    laboratories for further research and development activity, the 
    information specified in paragraph (a)(1) of this section need not be 
    reviewed and evaluated. (For purposes of this paragraph (a)(2), a 
    laboratory is defined as a contained research facility, where 
    relatively small quantities of microorganisms are used on a non-
    production basis, and where activities involve the use of containers 
    for reactions, transfers, and other handling of microorganisms designed 
    to be easily manipulated by a single individual.)
        (b) Notification to employees. (1) The manufacturer, importer, or 
    processor must notify the persons identified in Sec. 725.234(e) by 
    means of a container labeling system, conspicuous placement of notices 
    in areas where exposure may occur, written notification to each person 
    potentially exposed, or any other method of notification which 
    adequately informs persons of health risks which the manufacturer, 
    importer, or processor has reason to believe may be associated with the 
    microorganism, as determined under paragraph (a)(1) of this section.
        (2) If the manufacturer, importer, or processor distributes a 
    microorganism manufactured, imported, or processed under this section 
    to persons not in its employ, the manufacturer, importer, or processor 
    must in written form:
        (i) Notify those persons that the microorganism is to be used only 
    for research and development purposes.
        (ii) Provide the notice of health risks specified in paragraph 
    (b)(1) of this section.
        (3) The adequacy of any notification under this section is the 
    responsibility of the manufacturer, importer, or processor.
        (c) No applicability to general commercial use. A microorganism is 
    not exempt from reporting under subpart D of this part if any amount of 
    the microorganism, including as part of a mixture, is processed, 
    distributed in commerce, or used, for any commercial purpose other than 
    research and development, except where the microorganism is processed, 
    distributed in commerce, or used only as an impurity or as part of an 
    article.
         (d) Waste disposal. Quantities of the inactivated microorganism, 
    or mixtures or articles containing the inactivated microorganism, 
    remaining after completion of research and development activities may 
    be disposed of as a waste in accordance with applicable Federal, State, 
    and local regulations.
        (e) Impurities and articles. Quantities of research and development 
    microorganisms existing solely as impurities in a product or 
    incorporated into an article, in accordance with paragraph (c) of this 
    section, are not subject to the requirements of Sec. 725.234 and 
    paragraphs (a) and (b) of this section, once research and development 
    activities have been completed.
        (f) Pesticide uses. A person who manufactures, imports, or 
    processes a microorganism solely for research and development is not 
    required to comply with the requirements of this section if the 
    person's exclusive intention is to perform research and development 
    activities solely for the purpose of determining whether the 
    microorganism can be used as a pesticide.
        (g) Recordkeeping. A person who manufactures, imports, or processes 
    a microorganism under this section must retain the following records:
        (1) Records describing selection and use of containment and/or 
    inactivation controls required by Sec. 725.234(d)(3) and certification 
    by an authorized official required by Sec. 725.234(d)(2) for each 
    microorganism.
        (2) Copies or citations to information reviewed and evaluated under 
    paragraph (a)(1) of this section to determine the need to make any 
    notification of risk.
        (3) Documentation of prudent laboratory practices used instead of 
    notification and evaluation under paragraph (a)(2) of this section.
        (4) Documentation of the nature and method of notification under 
    paragraph (b)(1) of this section, including copies of any labels or 
    written notices used.
        (5) The names and addresses of any persons other than the 
    manufacturer, importer, or processor to whom the substance is 
    distributed, the identity of the microorganism, the amount distributed, 
    and copies of the notifications required under paragraph (b)(2) of this 
    section.

    TERA.
        (3) EPA may include conditions in its approval of the TERA that 
    would be stated in a TERA agreement under paragraph (c) of this 
    section.
        (4) If EPA concludes that the proposed research and development 
    activity may present an unreasonable risk of injury to human health or 
    the environment, EPA will deny the TERA and will provide reasons for 
    the denial in writing.
        (c) TERA agreement. (1) The TERA agreement is legally binding on 
    the TERA submitter and the Agency. The TERA submitter agrees to be 
    bound by the requirements set out in the agreement and also certifies 
    that all data submitted to the Agency is true and correct.
        (2) If EPA approves a TERA, the submitter must conduct the research 
    and development activity only as described in the TERA agreement and in 
    accordance with any conditions set forth by EPA in its approval of the 
    TERA agreement.
        (3) Any person who fails to comply with any requirement or 
    condition of the TERA agreement shall be in violation of sections 5 and 
    15 of TSCA and so subject to civil and criminal penalties under section 
    16 of TSCA.
    
    
    Sec. 725.288   Revocation or modification of TERA approval.
    
        (a) Significant questions about risk. (1) If, after approval of a 
    TERA under this subpart, EPA receives information which raises 
    significant questions about the Agency's determination that the 
    activity does not present an unreasonable risk of injury to human 
    health or the environment, EPA will notify the submitter in writing of 
    those questions.
        (2) The submitter may, within 10 days of receipt of EPA's notice, 
    provide in writing additional information or arguments concerning the 
    significance of the questions and whether EPA should modify or revoke 
    the approval of the TERA.
        (3) After considering any such information and arguments, EPA will 
    decide whether to change its determination regarding approval of the 
    TERA.
        (i) If EPA determines that it will continue to approve the TERA, it 
    will notify the submitter in writing. In continuing to approve a TERA, 
    EPA may prescribe additional conditions which must be followed by the 
    submitter. In this case, EPA may reserve the right to review the test 
    data and revoke the TERA approval after some time period.
        (ii) If EPA concludes that it can no longer approve the TERA, it 
    will notify the submitter in writing and state its reasons. In that 
    event, the submitter must terminate the research and development 
    activity within 48 hours of receipt of the notice in accordance with 
    directions provided by EPA in the notice.
        (b) Evidence of unreasonable risk. (1) If, after approval of a TERA 
    under this subpart, EPA receives information which indicates that the 
    proposed research and development activity will present an unreasonable 
    risk of injury to human health or the environment, EPA will notify the 
    submitter in writing and state its reasons.
        (2) The submitter must provide additional safeguards or terminate 
    the research and development activity in accordance with directions 
    provided by EPA in the notice.
        (3) The submitter may then submit additional information or 
    arguments concerning the matters raised by EPA and whether EPA should 
    modify or revoke the approval of the TERA in accordance with paragraph 
    (a)(2) of this section.
        (4) EPA will consider the information and arguments under paragraph 
    (a)(3) of this section.
        (5) The submitter may resume the activity only upon written notice 
    from EPA that EPA has approved resumption of the activity. In approving 
    resumption of an activity, EPA may prescribe additional conditions 
    which must be followed by the submitter.
        (c) Modifications. If, after approval of a TERA under this subpart, 
    the submitter concludes that it is necessary to alter the conduct of 
    the research and development activity in a manner which would result in 
    the activity being different from that described in the TERA agreement 
    and any conditions EPA prescribed in its approval, the submitter must 
    inform the EPA contact for the TERA and may not modify the activity 
    without the approval of EPA.

    unreasonable risk of injury to health and the environment as a result 
    of test marketing.
    Subpart G--Exemption for Microorganisms in General Commercial Use
    
    
    Sec. 725.400   Scope and purpose.
    
        (a) This subpart describes exemptions from reporting under subpart 
    D of this part, and from review under this part altogether, for 
    manufacturing and importing of certain new microorganisms for general 
    commercial use.
        (b) Recipient microorganisms eligible for the tiered exemption from 
    review under this part are listed in Sec. 725.420.

        (f) In lieu of complying with subpart D of this part, persons using 
    recipient microorganisms eligible for the tiered exemption may submit a 
    Tier II exemption request. The limited reporting requirements for the 
    Tier II exemption, including data requirements, are described in 
    Sec. Sec. 725.450 and 725.455.
        (g) EPA review procedures for the Tier II exemption are set forth 
    in Sec. 725.470.
        (h) Subparts A through C of this part apply to any submission under 
    this subpart.
    
    
    Sec. 725.420   Recipient microorganisms.
    
        The following recipient microorganisms are eligible for either 
    exemption under this part:
        (a) Acetobacter aceti.
        (b) Aspergillus niger.
        (c) Aspergillus oryzae.
        (d) Bacillus licheniformis.
        (e) Bacillus subtilis.
        (f) Clostridium acetobutylicum.
        (g) Escherichia coli K-12.
        (h)  Penicillium roqueforti.
        (i) Saccharomyces cerevisiae.
        (j) Saccharomyces uvarum.
    
    
    Sec. 725.421   Introduced genetic material.
    
        For a new microorganism to qualify for either exemption under this 
    subpart, introduced genetic material must meet all of the criteria 
    listed in this section.
        (a) Limited in size. The introduced genetic material must consist 
    only of the following:
        (1) The structural gene(s) of interest.
        (2) The regulatory sequences permitting the expression of solely 
    the gene(s) of interest.
        (3) Associated nucleotide sequences needed to move genetic 
    material, including linkers, homopolymers, adaptors, transposons, 
    insertion sequences, and restriction enzyme sites.
        (4) The nucleotide sequences needed for vector transfer.
        (5) The nucleotide sequences needed for vector maintenance.
        (b) Well characterized. For introduced genetic material, well 
    characterized means that the following have been determined:
        (1) The function of all of the products expressed from the 
    structural gene(s).
        (2) The function of sequences that participate in the regulation of 
    expression of the structural gene(s).
        (3) The presence or absence of associated nucleotide sequences.
        (c) Poorly mobilizable. The ability of the introduced genetic 
    material to be transferred and mobilized is inactivated, with a 
    resulting frequency of transfer of less than 10-8 transfer events 
    per recipient.
        (d) Free of certain sequences. The introduced genetic material must 
    not contain any part of the nucleotide sequences that encode the toxins 
    described in this paragraph (d). Although these toxins are listed 
    according to the source organism, it is use of the nucleotide sequences 
    that encode the toxins that are being restricted and not the use of the 
    source organisms. The source organisms are listed to provide 
    specificity in identification of sequences whose use is restricted. 
    Similar or identical sequences may be isolated from organisms other 
    than those listed below. Comparable toxin sequences, regardless of the 
    organism from which they are derived, must not be included in the 
    introduced genetic material. Toxin synonyms are included in 
    parentheses.
        (1) Sequences for protein synthesis inhibitor.

    are contained in Sec. Sec. 725.28 through 725.60. In addition, the 
    following procedures apply to EPA review of requests submitted under 
    this subpart:
        (a) Length of the review period. The review period for the request 
    will be 45 days from the date the Document Control Officer for the 
    Office of Pollution Prevention and Toxics receives a complete request, 
    or the date EPA determines the request is complete under Sec. 725.33, 
    unless the Agency extends the review period for good cause under 
    Sec. 725.56.
        (b) Criteria for review. EPA will review the request to determine 
    that the new microorganism complies with Sec. 725.428 and that its use 
    as described in the request will not present an unreasonable risk of 
    injury to health or the environment.
        (c) EPA decision regarding the Tier II exemption request. A 
    decision concerning a request under this subpart will be made by the 
    Administrator, or a designee.
        (d) Determination that the microorganism is ineligible for a Tier 
    II review. (1) EPA may determine that the manufacturer or importer is 
    not eligible for Tier II review, because the microorganism does not 
    meet the criteria under Sec. 725.428 or the Administrator, or a 
    designee, decides that there is insufficient information to determine 
    that the conditions of use of the microorganism as described in the 
    request will not present an unreasonable risk to health or the 
    environment.
        (2) If the Agency makes this determination, the Administrator, or a 
    designee will notify the manufacturer by telephone, followed by a 
    letter, that the request has been denied. The letter will explain 
    reasons for the denial.
        (3) If the request is denied, the manufacturer may submit the 
    information necessary to constitute a MCAN under subpart D of this 
    part.
        (e) Approval or denial of the Tier II exemption request. (1) No 
    later than 45 days after EPA receives a request, the Agency will either 
    approve or deny the request.
        (2) In approving a request, EPA may impose any restrictions 
    necessary to ensure that the microorganism will not present an 
    unreasonable risk of injury to health and the environment as a result 
    of general commercial use.
        (f) EPA may seek to enjoin the manufacture or import of a 
    microorganism in violation of this subpart, or act to seize any 
    microorganism manufactured or imported in violation of this section or 
    take other actions under the authority of sections 7 or 17 of the Act.

    in writing within 15 working days of the time the person develops 
    knowledge that the recipient is engaging in a significant new use, that 
    the recipient is engaging in a significant new use without submitting a 
    MCAN.
        (ii) That, within 15 working days of notifying the recipient as 
    described in paragraph (d)(1)(i) of this section, the person received 
    from the recipient, in writing, a statement of assurance that the 
    recipient is aware of the terms of the applicable section in subpart M 
    of this part and will not engage in the significant new use.
        (iii) That the person has promptly provided EPA enforcement 
    authorities with a copy of the recipient's statement of assurance 
    described in paragraph (d)(1)(ii) of this section. The copy must be 
    sent to the Director, Office of Compliance Monitoring (EN-342), 
    Environmental Protection Agency, 401 M St., SW., Washington, DC 20460.
        (2) If EPA notifies the manufacturer, importer, or processor that 
    the recipient is engaging in a significant new use after providing the 
    statement of assurance described in paragraph (d)(1)(ii) of this 
    section and without submitting a MCAN under this part, the 
    manufacturer, importer, or processor shall immediately cease 
    distribution to that recipient until the manufacturer, importer, or 
    processor or the recipient has submitted a MCAN under this part and the 
    MCAN review period has ended.
        (3) If, after receiving a statement of assurance from a recipient 
    under paragraph (d)(1)(ii) of this section, a manufacturer, importer, 
    or processor has knowledge that the recipient is engaging in a

        (iii) The manufacturer, importer, or processor has received notice 
    from EPA enforcement authorities that it may resume distribution to 
    that recipient.
    
    
    Sec. 725.912   Exemptions.
    
        Persons identified in Sec. Sec. 725.100(c) and 725.910 are not 
    required to submit a MCAN under subpart D of this part for a 
    microorganism identified in subpart M of this part, unless otherwise 
    specified in a specific section in subpart M, if:
        (a) The person submits a MCAN for the microorganism prior to the 
    promulgation date of the section in subpart M of this part which 
    identifies the microorganism, and the person receives written 
    notification of compliance from EPA prior to the effective date of such 
    section. The MCAN submitter must comply with any applicable requirement 
    of section 5(b) of the Act. The MCAN must include the information and 
    test data specified in section 5(d)(1) of the Act. For purposes of this 
    exemption, the specific section in subpart M of this part which 
    identifies the microorganism and Sec. Sec. 725.3, 725.15, 725.65, 
    725.70, 725.75, 725.100, and 725.900 apply; after the effective date of 
    the section in subpart M of this part which identifies the 
    microorganism, Sec. Sec. 725.105 and 725.910 apply and Sec. 725.920 
    continues to apply. EPA will provide the MCAN submitter with written 
    notification of compliance only if one of the following occurs:
        (1) EPA is unable to make the finding that the activities described 
    in the MCAN will or may present an unreasonable risk of injury to 
    health or the environment under reasonably foreseeable circumstances.
        (2) EPA and the person negotiate a consent order under section 5(e) 
    of the Act, such order to take effect on the effective date of the 
    section in subpart M of this part which identifies the microorganism.
        (b) The person is operating under the terms of a consent order 
    issued under section 5(e) of the Act applicable to that person. If a 
    provision of such section 5(e) order is inconsistent with a specific 
    significant new use identified in subpart M of this part, abiding by 
    the provision of the section 5(e) order exempts the person from 
    submitting a MCAN for that specific significant new use.
    
    
    Sec. 725.920   Exports and imports.
    
        (a) Exports. Persons who intend to export a microorganism 
    identified in subpart M of this part, or in any proposed rule which 
    would amend subpart M of this part, are subject to the export 
    notification provisions of section 12(b) of the Act. The regulations 
    that interpret section 12(b) appear at 40 CFR part 707.
        (b) Imports. Persons who import a substance identified in a 
    specific section in subpart M of this part are subject to the import 
    certification requirements under section 13 of the Act, which are 
    codified at 19 CFR Sec. Sec. 12.118 through 12.127 and 12.28. The EPA 
    policy in support of the import certification requirements appears at 
    40 CFR part 707.
    
    
    Sec. 725.950   Additional recordkeeping requirements for reporting of 
    significant new uses.
    
        Persons submitting a MCAN for a significant new use of a 
    microorganism must comply with the recordkeeping requirements of 
    Sec. 725.65. In addition, the following requirements apply:
        (a) At the time EPA adds a microorganism to subpart M of this part, 
    the Agency may specify appropriate recordkeeping requirements. Each 
    manufacturer, importer, and processor of the microorganism shall 
    maintain the records for 3 years from the date of their creation.
        (b) The records required to be maintained under this section may 
    include the following:
        (1) Records documenting the information contained in the MCAN 
    submitted to the Agency.
        (2) Records documenting the manufacture and importation volume of 
    the microorganism and the corresponding dates of manufacture and 
    import.
        (3) Records documenting volumes of the microorganism purchased 
    domestically by processors of the microorganism, names and addresses of 
    suppliers and corresponding dates of purchase.
        (4) Records documenting the names and addresses (including shipment 
    destination address, if different) of all persons outside the site of 
    manufacture or import to whom the manufacturer, importer, or processor 
    directly sells or transfers the microorganism, the date of each sale or 
    transfer, and the quantity of the microorganism sold or transferred on 
    such date.
    
    
    Sec. 725.975   EPA approval of alternative control measures.
    
        (a) In certain sections of subpart M of this part, significant new 
    uses for the identified microorganisms are described as the failure to 
    establish and implement programs providing for the use of either: 
    specific measures to control worker exposure to or release of 
    microorganisms which are identified in such sections, or alternative 
    measures to control worker exposure or environmental release which EPA 
    has determined provide substantially the same degree of protection as 
    the specified control measures. Persons who manufacture, import, or 
    process a microorganism identified in such sections and who intend to 
    employ alternative measures to control worker exposure or environmental 
    release must submit a request to EPA for a determination of equivalency 
    before commencing manufacture, import, or processing involving the 
    alternative control measures.
        (b) A request for a determination of equivalency must be submitted 
    in writing to the Office of Pollution Prevention and Toxics, Document 
    Control Officer, 7407, 401 M St., SW., Washington, DC 20460: ATTN: SNUR 
    Equivalency Determination, and must contain:
        (1) The name of the submitter.
        (2) The specific identity of the microorganism.
        (3) The citation for the specific section in subpart M of this part 
    which pertains to the microorganism for which the request is being 
    submitted.
        (4) A detailed description of the activities involved.
        (5) The specifications of the alternative worker exposure control 
    measures or environmental release control measures.
        (6) An analysis justifying why such alternative control measures 
    provide substantially the same degree of protection as the specific 
    control measures identified in the specific section in subpart M of 
    this part which pertains to the microorganism for which the request is 
    being submitted.
        (7) The data and information described in Sec. Sec. 725.155 and 
    725.160 of this part unless such data and information have already been 
    submitted to EPA's Office of Pollution Prevention and Toxics.
        (c) Requests for determinations of equivalency will be reviewed by 
    EPA within 45 days. Determinations under this paragraph will be made by 
    the Director, or a designee. Notice of the results of such 
    determinations will be mailed to the submitter.
        (d) If EPA notifies the submitter under paragraph (c) of this 
    section that EPA has determined that the alternative control measures 
    provide substantially the same degree of protection as the specified 
    control measures identified in the specific section of subpart M of 
    this part which pertains to the microorganism for which the request is 
    being submitted, the submitter may commence manufacture, import, or 
    processing in accordance with the specifications for alternative worker 
    exposure control measures or environmental release control measures 
    identified in the submitter's request, and may alter any corresponding 
    notification to workers to reflect such alternative controls. 
    Deviations from the activities described in the EPA notification 
    constitute a significant new use and are subject to the requirements of 
    this part.
    
    
    Sec. 725.980   Expedited procedures for issuing significant new use 
    rules for microorganisms subject to section 5(e) orders.
    
        (a) Selection of microorganisms. (1) In accordance with the 
    expedited process specified in this section, EPA will issue significant 
    new use notification requirements for each new microorganism that, 
    after MCAN review under subpart D of this part, becomes subject to a 
    final order issued under section 5(e) of the Act, except for an order 
    that prohibits manufacture and import of the microorganism, unless EPA 
    determines that significant new use notification requirements are not 
    needed for the microorganism.
        (2) If EPA determines that significant new use notifications 
    requirements are not needed for a microorganism that is subject to a 
    final order issued under section 5(e) of the Act, EPA will issue a 
    notice in the Federal Register explaining why the significant new use 
    requirements are not needed.
        (b) Designation of requirements. (1) The significant new use 
    notification and other specific requirements will be based on and be 
    consistent with the provisions included in the final order issued for 
    the microorganism under section 5(e) of the Act. EPA may also designate 
    additional activities as significant new uses which will be subject to 
    notification.
        (2) Significant new use requirements and other specific 
    requirements designated under this section will be listed in subpart M 
    of this part. For each microorganism, subpart M of this part will 
    identify:
        (i) The microorganism name.
        (ii) The activities designated as significant new uses.
        (iii) Other specific requirements applicable to the microorganism, 
    including recordkeeping requirements or any other requirements included 
    in the final section 5(e) order.
        (c) Procedures for issuing significant new use rules. (1) Possible 
    processes. EPA will issue significant new use rules under this section 
    by one of the following three processes: direct final rulemaking, 
    interim final rulemaking, or notice and comment rulemaking. EPA will 
    use the direct final rulemaking process to issue significant new use 
    rules unless it determines that, in a particular case, one of the other 
    processes is more appropriate.
        (2) Notice in the Federal Register. Federal Register documents 
    issued to propose or establish significant new uses under this section 
    will contain the following:
        (i) The microorganism identity or, if its specific identity is 
    claimed confidential, an appropriate generic microorganism name and an 
    accession number assigned by EPA.
        (ii) The MCAN number.
        (iii) A summary of EPA's findings under section 5(e)(1)(A) of the 
    Act for the final order issued under section 5(e).
        (iv) Designation of the significant new uses subject to, or 
    proposed to be subject to, notification and any other applicable 
    requirements.
        (v) Any modification of subpart M of this part applicable to the 
    specific microorganism and significant new uses.
        (vi) If the Federal Register document establishes a final rule, or 
    notifies the public that a final rule will not be issued after public 
    comment has been received, the document will describe comments received 
    and EPA's response.
        (3) Direct final rulemaking. (i) EPA will use the direct final 
    rulemaking procedure to issue a significant new use rule, when specific 
    requirements will be based on and be consistent with the provisions 
    included in the final order issued for the microorganism under section 
    5(e) of the Act. The Agency will issue a final rule in the Federal 
    Register following its decision to develop a significant new use rule 
    under this section for a specific new microorganism.
        (ii) The Federal Register document will state that, unless written 
    notice is received by EPA within 30 days of publication that someone 
    wishes to submit adverse or critical comments, the rule will be 
    effective 60 days from the date of publication. The written notice of 
    intent to submit adverse or critical comments should state which 
    SNUR(s) will be the subject of the adverse or critical comments, if 
    several SNURs are established through the direct final rule. If notice 
    is received within 30 days that someone wishes to submit adverse or 
    critical comments, the section(s) of the direct final rule containing 
    the SNUR(s) for which a notice of intent to comment was received will 
    be withdrawn by EPA issuing a document in the final rule section of the 
    Federal Register, and a proposal will be published in the proposed rule 
    section of the Federal Register. The proposal will establish a 30-day 
    comment period.
        (iii) If EPA, having considered any timely comments submitted in 
    response to the proposal, decides to establish notification 
    requirements under this section, EPA will issue a final rule adding the 
    microorganism to subpart M of this part and designating the significant 
    new uses subject to notification.
        (4) Interim final rulemaking. (i) EPA will use the interim final 
    rulemaking procedure to issue a significant new use rule, when specific 
    requirements will be based on and be consistent with the provisions 
    included in the final order issued for the microorganism under section 
    5(e) of the Act. The Agency will issue an interim final rule in the 
    Federal Register following its decision to develop a significant new 
    use rule for a specific new microorganism. The document will state 
    EPA's reasons for using the interim final rulemaking procedure.
        (A) The significant new use rule will take effect on the date of 
    publication.
        (B) Persons will be given 30 days from the date of publication to 
    submit comments.
        (ii) Interim final rules issued under this section shall cease to 
    be in effect 180 days after publication unless, within the 180-day 
    period, EPA issues a final rule in the Federal Register responding to 
    any written comments received during the 30-day comment period 
    specified in paragraph (c)(5)(i)(B) of this section and promulgating 
    final significant new use notification requirements and other 
    requirements for the microorganism.
        (5) Notice and comment rulemaking. (i) EPA will use a notice and 
    comment procedure to issue a significant new use rule, when EPA is 
    designating additional activities which are not provisions included in 
    the final order issued for the microorganism under section 5(e) of the 
    Act as significant new uses which will be subject to notification. EPA 
    will issue a proposal in the Federal Register following its decision to 
    develop a significant new use rule under this section for a specific 
    new microorganism. Persons will be given 30 days to comment on whether 
    EPA should establish notification requirements for the microorganism 
    under this part.
        (ii) If EPA, having considered any timely comments, decides to 
    establish notification requirements under this section, EPA will issue 
    a final rule adding the microorganism to subpart M of this part and 
    designating the significant new uses subject to notification.
        (d) Schedule for issuing significant new use rules. (1) Unless EPA 
    determines that a significant new use rule should not be issued under 
    this section, EPA will issue a proposed rule, a direct final rule, or 
    an interim final rule within 180 days of receipt of a valid notice of 
    commencement under Sec. 725.190 of this part.
        (2) If EPA receives adverse or critical significant comments 
    following publication of a proposed or interim final rule, EPA will 
    either withdraw the rule or issue a final rule addressing the comments 
    received.
    
    
    Sec. 725.984   Modification or revocation of certain notification 
    requirements.
    
        (a) Criteria for modification or revocation. EPA may at any time 
    modify or revoke significant new use notification requirements for a 
    microorganism which has been added to subpart M of this part using the 
    procedures of Sec. 725.980. Such action may be taken under this section 
    if EPA makes one of the following determinations, unless other 
    information shows that the requirements should be retained:
        (1) Test data or other information obtained by EPA provide a 
    reasonable basis for concluding that activities designated as 
    significant new uses of the microorganism will not present an 
    unreasonable risk of injury to health or the environment.
        (2) EPA has promulgated a rule under section 4 or 6 of the Act, or 
    EPA or another agency has taken action under another law, for the 
    microorganism that eliminates the need for significant new use 
    notification under section 5(a)(2) of the Act.
        (3) EPA has received MCANs for some or all of the activities 
    designated as significant new uses of the microorganism and, after 
    reviewing such MCANs, concluded that there is no need to require 
    additional notice from persons who propose to engage in identical or 
    similar activities.
        (4) For a microorganism added to subpart M of this part under 
    Sec. 725.980, EPA has examined new information, or has reexamined the 
    test data or other information supporting its finding under section 
    5(e)(1)(A)(ii)(I) of the Act and has concluded that a rational basis no 
    longer exists for the findings that activities involving the 
    microorganism may present an unreasonable risk of injury to human 
    health or the environment required under section 5(e)(1)(A) of the Act.
        (5) For a microorganism added to subpart M of this part under 
    Sec. 725.980, certain activities involving the microorganism have been 
    designated as significant new uses pending the completion of testing, 
    and adequate test data developed in accordance with applicable 
    procedures and criteria have been submitted to EPA.
        (b) Procedures for limitation or revocation. Modification or 
    revocation of significant new use notification requirements for a 
    microorganism that has been added to subpart M of this part using the 
    procedures described in Sec. 725.980 may occur either at EPA's 
    initiative or in response to a written request.
        (1) Any affected person may request modification or revocation of 
    significant new use notification requirements for a microorganism that 
    has been added to subpart M of this part using the procedures described 
    in Sec. 725.980 by writing to the Director, or a designee, and stating 
    the basis for such request. The request must be accompanied by 
    information sufficient to support the request. All requests should be 
    sent to the TSCA Document Processing Center (7407), Room L-100, U.S. 
    Environmental Protection Agency, 401 M St., SW., Washington, DC 20460, 
    ATTN: Request to amend SNUR.
        (2) The Director, or a designee, will consider the request, make a 
    determination whether to initiate rulemaking to modify the 
    requirements, and notify the requester of that determination by 
    certified letter. If the request is denied, the letter will explain why 
    EPA has concluded that the significant new use notification 
    requirements for that microorganism should remain in effect.
        (3) If EPA concludes that significant new use notification 
    requirements for a microorganism should be limited or revoked, EPA will 
    propose the changes in a notice in the Federal Register, briefly 
    describe the grounds for the action, and provide interested parties an 
    opportunity to comment.
