    Registration Requirements for Antimicrobial Pesticide Products 
    and Other Pesticide Regulatory Changes
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: EPA is proposing to establish procedures for the registration 
    of antimicrobial products, as well as implement other provisions of the 
    Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended 
    by the Food Quality Protection Act. This proposal is required by FIFRA.
        In addition to registration procedures for antimicrobial products, 
    EPA also proposes to establish labeling standards for antimicrobial 
    public health products, which will ensure that these products are 
    appropriately labeled for the level of antimicrobial activity they 
    demonstrate; to modify its notification process for antimicrobial 
    products to conform to the statutorily prescribed process; and to 
    exempt certain antimicrobial products from FIFRA regulation.
        EPA believes that the new procedures and provisions will streamline 
    and improve the registration process, increase consistency and 
    certainty for antimicrobial producers, reduce the timeframes for EPA 
    decisions on antimicrobial registrations, increase public health 
    protection by ensuring the continued efficacy of antimicrobial public 
    health pesticides, and promote international harmonization efforts.
        EPA is also proposing to implement a number of general provisions 
    of FIFRA that are not specific to antimicrobial pesticides. EPA 
    proposes to interpret the applicability of the new FIFRA definition of 
    ``pesticide'' that excludes liquid chemical sterilants from FIFRA 
    regulation and includes nitrogen stabilizers, and to describe 
    requirements pertaining to use dilution labeling. These proposals are 
    intended to implement new provisions of FIFRA, and to update current 
    regulations and procedures.
        Finally, EPA is proposing technical, conforming and organizational 
    changes to portions of its regulations on pesticide registration and 
    labeling for clarity and understanding.

    III. Authority
    
    A. The Federal Insecticide, Fungicide, and Rodenticide Act
    
        This proposal is issued under the authority of FIFRA sections 3 and 
    25, 7 U.S.C. 136a and 136w. Under FIFRA, a pesticide product may not be 
    distributed or sold in the United States unless it is registered with 
    the EPA. Registration is a licensing process in which EPA evaluates 
    each proposed product, its uses, and its labeling to determine whether 
    it meets the standard for registration in FIFRA section 3(c)(5). That 
    standard states that, for a registration to be approved, EPA must 
    determine that the pesticide product, when used in accordance with its 
    intended uses and with widespread and commonly recognized practice, 
    will not cause unreasonable adverse effects on the environment. The 
    registration standard is a risk/benefit standard, which must take into 
    account the economic, social and environmental costs and benefits of 
    use.
    
    B. The Food Quality Protection Act
    
        On August 3, 1996, Congress enacted the Food Quality Protection Act 
    (FQPA), modifying FIFRA and the Federal Food, Drug and Cosmetic Act 
    (FFDCA). Most of its provisions were effective immediately, although 
    some require implementing regulations. Units IV. and V. discuss the 
    statutory provisions of FIFRA as amended by FQPA that this proposal 
    would implement.
    
    C. The Antimicrobial Regulation Technical Corrections Act
    
        On October 30, 1998, Congress enacted the Antimicrobial Regulation 
    Technical Corrections Act (ARTCA), which modified the Federal Food, 
    Drug, and Cosmetic Act (FFDCA) to effectively transfer authority over a 
    number of pesticide residues to FDA. Regulatory authority over these 
    residues had originally been transferred to EPA by FQPA. Unit XI. 
    discusses the
    
    [[Page 50674]]
    
    consequences of this statute and how EPA and FDA jurisdiction over 
    antimicrobial pesticide residues in food has been allocated by ARTCA.
    
    IV. Antimicrobial Provisions Addressed in this Proposal
    
    A. Overview
    
        The FQPA amendments to FIFRA focus attention on antimicrobial 
    pesticides specifically, and the procedural framework under which the 
    Agency reviews and approves applications for registration and amendment 
    of antimicrobial pesticides. This unit discusses the new statutory 
    provisions for antimicrobial products and how this proposal satisfies 
    each statutory requirement.
        1. Under FIFRA section 3(h)(1), EPA must evaluate its registration 
    process to identify improvements and reforms that would reduce 
    historical review times for antimicrobial applications.
        2. FIFRA section 3(h)(2) defines the goals for review that process 
    improvements should be designed to achieve, expressed as review period 
    reduction goals for various types of applications.
        3. Under FIFRA section 3(h)(3)(A), EPA must propose regulations 
    that address a number of application process elements, with the goal of 
    implementing specified process management improvements and meeting 
    section 3(h)(2) goals. EPA is today proposing these regulations. Unit 
    VIII. discusses each of following statutorily mandated elements, and 
    briefly describes how today's proposal addresses those requirements:
        a. Defining the classes of antimicrobial use patterns.
        b. Defining types of application review.
        c. Conforming reviews to risks and benefits.
        d. Ensuring efficacy.
        e. Meeting review time goals.
        4. Under FIFRA section 3(h)(3)(B), EPA must in its final rule 
    consider specified types of application and process improvements that 
    would contribute to meeting the review time goals or otherwise simplify 
    the application process, including:
        a. Certification mechanisms for applications.
        b. Certification of laboratories.
        c. Expanded use of notification and non-notification procedures.
        d. Clarification of completeness criteria for applications.
        e. Revised procedures for application review.
        f. Allocation of resources.
        In order to consider these topics for inclusion in the final rule, 
    EPA must offer proposals or options for notice and comment today that 
    could be incorporated into a final rule. EPA is today proposing 
    regulations addressing expanded use of notification procedures (see 
    Unit XVI.) and completeness criteria (See Unit VIII.F.). EPA has 
    considered certification mechanisms for applicants, and, as discussed 
    in Unit IV.G., may establish such a mechanism administratively. EPA has 
    also considered the possibility of laboratory certification programs, 
    but is not making a specific proposal at this time.
        Under FIFRA section 3(h)(3)(B), a final regulation must be 
    promulgated no later than 240 days after the end of the comment period 
    for those portions of this proposal required by FIFRA section 3(h).
    
    B. Defining Classes of Antimicrobial Use Patterns
    
        FIFRA section 3(h)(3)(A)(ii)(I) requires that EPA ``define the 
    various classes of antimicrobial use patterns.'' EPA has developed a 
    comprehensive list of antimicrobial use patterns in conjunction with 
    its upcoming part 158 proposal on antimicrobial data requirements. That 
    proposal would establish a set of data requirements that apply solely 
    to antimicrobial pesticides. EPA has developed an appendix of all 
    current antimicrobial use patterns, divided into 12 use categories 
    having common exposures or other similarities. The proposal meshes with 
    the statutory mandate to identify classes of antimicrobial use patterns 
    by defining, for each use category, the data requirements that apply. 
    Unit VIII.D. includes a list of the use categories. A copy of the full 
    draft Use Appendix is in the docket for this proposal. EPA intends its 
    proposal of part 158 data requirements to satisfy the statutory 
    requirement to define classes of antimicrobial use patterns.
    
    C. Defining Types of Application Reviews
    
        FIFRA section 3(h)(3)(A)(ii)(II) requires that EPA ``differentiate 
    the types of review undertaken for antimicrobial pesticides.'' Since 
    the primary purpose of differentiating types of review is to ensure 
    that review time goals are met, EPA views the statutory requirement as 
    equivalent to defining the types of applications associated with the 
    review periods in section 3(h)(2). Proposed Sec. 152.445 addresses the 
    various application types, and describes the general criteria EPA uses 
    to characterize an application. EPA intends that this section will 
    satisfy the statutory requirement to differentiate types of reviews, 
    and also in part will satisfy the requirement for setting out differing 
    levels of data requirements for various classes of products under FIFRA 
    section 3(h)(3)(A)(ii)(I).
    
    D. Conforming Degree of Review to Risks and Benefits
    
        FIFRA section 3(h)(3)(A)(ii)(III) requires that EPA ``conform the 
    degree and type of review to the risks and benefits presented by 
    antimicrobial pesticides and the function of review under this Act, 
    considering the use patterns of the product, toxicity, expected 
    exposure and product type.''
        The function of review under FIFRA for any pesticide product, not 
    just an antimicrobial pesticide, is grounded in the registration 
    standards of FIFRA section 3(c)(5). As such, EPA review must:
        1. Assess the risks and benefits of the pesticide and its use, 
    relevant to the determination of unreasonable adverse effects. In the 
    case of a public health antimicrobial pesticide, a determination that 
    the product is efficacious when used as directed is central to a 
    benefits assessment.
        2. Determine the adequacy of the pesticide labeling in directing 
    the pesticide user as to intended and safe use of the pesticide, 
    thereby minimizing potential adverse effects to the user and the 
    environment.
        EPA believes that its proposed part 158 regulation defining use 
    categories and data requirements clearly acknowledges that different 
    use patterns have different exposure patterns and risks. The data 
    requirements for each use category are commensurate with the potential 
    exposures and risks associated with that use pattern, and in some cases 
    are tiered so that higher exposures or higher risks require a second 
    level of data. The amount and types of data required in and of 
    themselves dictate a review process that is more detailed, requiring a 
    more complex assessment for these potentially higher exposures or 
    higher toxicity. Therefore, in issuing part 158, EPA intends that the 
    mandate to conform the degree and type of review to risks and benefits 
    of use will be satisfied.
    
    E. Ensuring Efficacy
    
        FIFRA section 3(c)(5) has required since 1972 that the composition 
    of a pesticide be such as to warrant the claims made for it, i.e., that 
    a product work as claimed. Moreover, the registrant must ensure that 
    the pesticide product continues to meet that efficacy standard as long 
    as the product is registered. What has changed over time is the manner 
    in which EPA is assured of product efficacy. Until 1980, EPA
    
    [[Page 50675]]
    
    reviewed efficacy data for every pesticide product prior to 
    registration, and thus could assure that, at least at the time of 
    registration, each product would perform as intended. In 1980, EPA 
    determined that, for pesticides of economic or aesthetic significance, 
    the marketplace can be relied upon to weed out inefficacious products. 
    EPA reasoned that because users can determine for themselves whether a 
    product works, and are motivated by economic reasons to ensure that 
    they are using the most efficacious products, less efficacious products 
    would not survive in a highly competitive marketplace. Accordingly, EPA 
    no longer routinely reviews efficacy data prior to registration for 
    most insecticides, fungicides, herbicides, and non-public health 
    antimicrobial pesticides. Registrants must maintain data demonstrating 
    efficacy in their files, and submit it to the Agency upon request.
        EPA recognized, however, that it could not reduce its efficacy 
    oversight of public health products and still be assured of product 
    efficacy. The failure of public health products to work as intended 
    could have consequences far beyond those of mere economic or aesthetic 
    significance. Consumers and public health officials must have assurance 
    that a product will work against pests that pose public health threats. 
    Many public health products are antimicrobial pesticides registered to 
    control bacteria, viruses, protozoa, and other microorganisms 
    pathogenic to man (others are insecticides and rodenticides controlling 
    pests that are vectors of disease in man). Unlike insects or weeds, 
    microbial pests cannot be seen, and users cannot determine by 
    observation whether the product actually performs as claimed. 
    Therefore, EPA cannot rely upon the users or marketplace forces to 
    ensure product efficacy. Accordingly, EPA has continued to review 
    efficacy data for public health products prior to registration.
        Subdivision G of the Pesticide Assessment Guidelines describes the 
    efficacy tests required, and the Labeling Guidelines for Pesticide Use 
    Directions - Antimicrobial Products (Subdivision H) contain the 
    performance standards that EPA uses to ensure that antimicrobial 
    products achieve an acceptable level of efficacy for the claims made. 
    The Pesticide Assessment Guidelines are available from the National 
    Technical Information Service, 5285 Port Royal Road, Springfield, VA 
    22161.
        FIFRA section 3(h)(3)(A)(ii)(IV) requires EPA to ``ensure that the 
    registration process is sufficient to maintain antimicrobial pesticide 
    efficacy and that antimicrobial pesticide products continue to meet 
    product performance standards and effectiveness levels for each type of 
    label claim made.'' At first glance, this language may appear merely to 
    reinforce the existing efficacy standard of FIFRA section 3(c)(5) that, 
    to be registered, a product must be efficacious. On closer reading, 
    however, it is clear that the language carries a broader mandate making 
    explicit the role of the registration process in ensuring continued 
    efficacy after registration.
        EPA has relied on post-registration mechanisms, including 
    enforcement monitoring, good laboratory practice monitoring and data 
    audits, testing by EPA and States as co-regulators, registrant 
    reporting under FIFRA section 6(a)(2), and user complaints to target 
    inefficacious products in the marketplace. In recent years, enforcement 
    actions have found a number of incidents of product failure which have 
    called into question the ability or willingness of producers to ensure 
    and maintain the efficacy of their products after registration. As a 
    result, EPA has since 1990 undertaken a systematic testing program for 
    antimicrobial pesticides. In cooperation with FDA, EPA has tested 
    sterilant products and has brought a number of enforcement and 
    regulatory actions against products found to be inefficacious. EPA is 
    now testing tuberculocides and hospital disinfectants.
        After a product has been identified as failing in efficacy, EPA may 
    use enforcement measures (such as Stop Sale, Use and Removal Orders) to 
    correct problems. EPA may also use remedies such as cancellation of 
    registration under FIFRA section 6 to remove inefficacious products 
    from the marketplace. EPA has found that post-registration reporting, 
    monitoring, testing and cancellation processes can be cumbersome and 
    time-consuming. In some cases, products that EPA has found to be 
    inefficacious have taken years for resolution through the hearing and 
    appeals processes available to registrants.
        EPA agrees wholeheartedly that measures to strengthen the Agency's 
    oversight of antimicrobial efficacy as part of registration are 
    desirable. Today's proposal contains two specific provisions to improve 
    and strengthen EPA's regulatory oversight of the efficacy of public 
    health antimicrobial pesticides:
        1. EPA proposes to incorporate into its regulations, as subpart W 
    of part 156, the efficacy performance standards for public health 
    products that are now contained only in its Labeling Guidelines. Unit 
    XII. further discusses efficacy performance standards for public health 
    antimicrobial pesticides.
        2. EPA proposes to limit the duration of registrations bearing 
    public health claims to 5 years. In order to extend the registration 
    for an additional 5 years, each registrant would have to confirm by 
    analysis that the product composition was the same as that in Agency 
    files previously demonstrated to be efficacious, and that the product 
    continued to meet efficacy standards specified in subpart W for each 
    public health claim. Unit IX. discusses the 5-year duration provision 
    in greater detail.
        EPA believes that these two regulatory provisions will fulfill the 
    statutory requirement that EPA ensure continued product efficacy 
    through the registration process.
    
    F. Implementing Deadlines for Process Management
    
        FIFRA section 3(h)(3)(A)(ii)(V) requires that EPA ``implement 
    effective and reliable deadlines for process management.'' EPA believes 
    that the ``deadlines'' referred to are those contained in FIFRA section 
    3(h)(1), which requires EPA to identify and evaluate reforms to the 
    antimicrobial registration process; FIFRA section 3(h)(2), which 
    establishes goals for reduction of review periods for antimicrobial 
    applications for registration; and FIFRA section 3(h)(3)(D), which 
    establishes default review periods that apply if EPA fails to issue its 
    final antimicrobial rule by the statutorily required deadline. As 
    discussed more fully in Unit VIII.H., EPA is today proposing in 
    Sec. 152.457 to adopt the ``goal'' review periods rather than the 
    ``default'' review periods.
    
    G. Certification Process for Regulatory Actions
    
        FIFRA section 3(h)(3)(B)(iii)(I) requires that, in issuing final 
    regulations, EPA must ``consider the establishment of a certification 
    process for regulatory actions involving risks that can be responsibly 
    managed, consistent with the degree of risk, in the most cost-efficient 
    manner.''
        Certification statements are currently permitted by 
    Sec. 152.44(b)(2) for various types of amendments to registration when 
    directed by EPA. Typically, EPA uses certification to accomplish 
    specific changes to registration (frequently labeling changes). EPA has 
    included in this proposal a broader provision that would allow the 
    Agency to implement self-certification programs as needed in
    
    [[Page 50676]]
    
    the future administratively. Unit VIII.A. discusses further this 
    provision.
        With respect to data certification, EPA has considered two self-
    certification programs in the recent past, and has implemented one of 
    these. PR Notice 98-1, Self-Certification of Product Chemistry Data, 
    was issued on January 12, 1998. In that notice, EPA describes the types 
    of product chemistry information (product characteristics) that can be 
    supplied to the Agency together with a self-certification that the data 
    were conducted according to EPA Guidelines. Under this program, EPA 
    would generally review only the summarized results of testing at the 
    time of application, but could review full study reports if EPA 
    determines that a complete evaluation of the study is warranted. Review 
    of the summary results of testing rather than of the complete study 
    report would decrease the time needed for all applications for 
    registration of new products and reregistration of existing products.
        EPA also considered a similar self-certification procedure for 
    acute toxicity data, and intends in the future to implement such a 
    program for antimicrobial products only. EPA originally considered an 
    acute toxicity data self-certification program because a backlog of 
    applications requiring acute toxicity data review extended review 
    periods while applications waited in queue. The certification mechanism 
    considered would have been available only with respect to a study 
    indicating that the product should be assigned to Toxicity Category III 
    or IV. The certification procedure was viewed as a means of reducing 
    the resources needed for review, and thus making more decisions with 
    the same level of resources. At the same time, EPA recognized that the 
    certification procedure could also reduce to some extent the Agency's 
    confidence in hazard and precautionary statements on labeling. Since 
    EPA issued its notice for comment, however, the Agency has achieved a 
    significant reduction in the backlog and consequently in the review 
    times for applications in the queue. The Agency decided therefore not 
    to pursue a certification approach for acute toxicity studies at this 
    time.
        Although EPA has decided not to adopt such an approach for 
    pesticides in general, the Agency has decided to consider a pilot 
    program that allows applicants for registration of antimicrobial 
    product to certify the results of an acute toxicity study when the test 
    data would indicate the product is in Toxicity Category I (the highest 
    toxicity category). Because such a product would be subject to the most 
    stringent labeling requiements, applicants would have no incentive to 
    certify that a product of lower toxicity was in Toxicity Category I. 
    Moreover, EPA's review of such data would add little value and would 
    use limited resources. EPA invites comment on this proposed approach to 
    certification of acute toxicity data, which would be implemented by a 
    notice to registrants if EPA decides to adopt it.
    
    H. Certification of Laboratories
    
        FIFRA section 3(h)(3)(B)(iii)(II) requires EPA to ``consider the 
    establishment of a certification process by approved laboratories as an 
    adjunct to the review process.'' EPA currently has underway a broad 
    program across the Agency evaluating the feasibility of laboratory 
    accreditation mechanisms for a variety of program and regulatory needs. 
    The Office of Pesticide Programs has also been actively working with 
    outside groups, such as the Chemical Specialties Manufacturers' 
    Association to further their efforts to develop laboratory 
    accreditation programs for antimicrobial products. EPA has considered 
    whether a program could be instituted at this time for antimicrobial 
    products, and believes that these efforts need further evaluation and 
    development before being integrated into the Agency's regulatory 
    programs. EPA intends to continue its cooperative work, and to fold its 
    efforts into the larger Agency process. Thus, EPA is not today 
    proposing a specific laboratory accreditation process as part of this 
    proposed rule.
    
    I. Notification Processes
    
        FIFRA section 3(h)(3)(B)(iii)(III)(aa) requires that, in issuing 
    final regulations, EPA must use ``expanded use of notification and non-
    notification procedures.'' This requirement dovetails neatly with the 
    statutorily expanded scope of notifications under FIFRA section 
    3(c)(9). EPA is today proposing to include in new Sec. 152.446 the new 
    procedures to expand the use of notification as a mechanism for the 
    label modification as directed by section 3(c)(9).
    
    J. Revised Procedures for Application Review
    
        FIFRA section 3(h)(3)(B)(iii)(III)(bb) requires that, in issuing 
    final regulations, EPA must use ``revised procedures for application 
    review.'' As outlined in Unit VII, EPA's current regulations for 
    registration of pesticide products, including antimicrobial pesticides, 
    are generally limited to describing the applicant's and Agency's 
    responsibilities and interactions. The summary description given in 
    that unit is similar for all pesticides. EPA intends to issue or revise 
    its current non-regulatory guidance documents that address the 
    application process in greater detail. To the extent that EPA develops 
    different procedures for antimicrobial products than for other 
    products, EPA will make those procedures available via direct notice to 
    affected registrants, and will make them widely available by all 
    feasible means, including electronic accessibility.
        The Agency has already implemented a number of administrative 
    reforms to improve the process, including revised procedures for 
    review. Since FQPA was enacted, the Agency has established a separate 
    Division solely responsible for antimicrobial products. The new 
    Antimicrobials Division is charged with all aspects of antimicrobial 
    regulation, and includes a full complement of scientific personnel in 
    biology, microbiology, chemistry, toxicology, and other scientific 
    disciplines, as well as an ombudsman to deal directly with registrant 
    issues and concerns.
        The new Division has focussed initially on meeting the review 
    period goals established by the statute for all new applications. To 
    assist this effort, a dedicated Expedited Review Team has been formed 
    for the purpose of processing notifications and screening and 
    processing applications that are ``fast-track'' or with review periods 
    of 90 days or less. By identifying and handling the less complex 
    actions, this team allows the Division to channel its scientific and 
    management resources into review of applications that are of higher 
    priority or that require in-depth review. The Division has added more 
    Product Managers, so that each Product Manager has a smaller and more 
    focussed product universe.
        The Division has also targeted increased outreach, communication 
    and information exchange as a high priority. Training materials, 
    information sheets, operating procedures and science reviews have been 
    developed or reevaluated for streamlining opportunities.
        Additional administrative accomplishments and plans are detailed in 
    the Agency's first progress report to Congress, Streamlining 
    Registration of Antimicrobial Pesticides, July 1997. EPA will issue 
    this report annually as required by section 3(h)(4). Each report will 
    identify further progress in management and administrative reforms.
    
    K. Allocation of Resources
    
        FIFRA section 3(h)(3)(B)(iii)(III)(cc) requires that, in issuing 
    final
    
    [[Page 50677]]
    
    regulations, EPA must address ``allocation of appropriate resources to 
    ensure streamlined management of antimicrobial pesticide 
    registrations.'' The allocation of resources is not a reform that can 
    be accomplished by Agency regulations, and EPA is not proposing any 
    regulations for doing so. Budget and resource allocations are guided by 
    Executive branch and Congressional priorities and are determined year 
    by year based on overall needs of the Agency and the pesticide program.
    
    L. Completeness of Applications
    
        FIFRA section 3(h)(3)(B)(iii)(IV) requires that, in issuing final 
    regulations, EPA must ``clarify criteria for determination of the 
    completeness of an application.'' EPA is today proposing in Sec. 152.3 
    a definition of a ``complete application'' for all registration 
    applications. In addition, specific to antimicrobial products, and 
    directly responsive to the requirement of FIFRA section 3(h)(3)(B), EPA 
    is proposing in Sec. 152.450 to describe in detail the contents of an 
    application, and the criteria that will be used to judge the 
    completeness of the application as a whole, and of its individual 
    components. EPA's proposals are discussed further in Unit VIII.F.
    
    V. Other Statutory Provisions Addressed in this Proposal
    
    A. Changes to the Definition of ``Pesticide''
    
        FQPA modified FIFRA section 2(u) to exclude certain liquid chemical 
    sterilant products from the definition of ``pesticide,'' and to include 
    certain nitrogen stabilizer products. This provision was effective on 
    August 3, 1996. In recognition of this provision, EPA is proposing to 
    add a new Sec. 152.6 entitled ``Substances excluded from regulation by 
    FIFRA.'' EPA has issued a notice to registrants, entitled ``Liquid 
    Chemical Sterilant Products'' (PR Notice 98-2; January 15, 1998), 
    explaining how it will treat liquid chemical sterilants affected by 
    section 2(u). Units XIV. and XV. discuss chemical sterilants and 
    nitrogen stabilizers.
    
    B. Notification Procedures
    
        FIFRA section 3(c)(9)(C) now authorizes registrants of 
    antimicrobial products to make certain defined labeling modifications 
    by notification to the Agency instead of amendment, and establishes a 
    procedure for notifications and Agency decisions. This provision was 
    effective on August 3, 1996, and the new procedures are exclusive to 
    antimicrobial products. Today's proposal codifies these new 
    notification procedures. The substance of the expanded notifications 
    permitted by FIFRA section 3(c)(9) is issued in notices to registrants 
    (PR Notices), and not in today's proposal. Unit XVI. discusses 
    antimicrobial notifications.
    
    C. Use Dilution Labeling
    
        FIFRA section 3(c)(9)(D) authorizes registrants to include on their 
    labeling precautionary statements about the product as diluted for use 
    (use dilution labeling). This provision was effective on August 3, 
    1996. EPA proposes to reformat its human hazard labeling requirements 
    in Sec. 156.10(h) and to incorporate use dilution requirements in 
    appropriate sections. Unit XIII.A. discusses use dilution labeling.
    
    VI. What is an Antimicrobial Pesticide?
    
        EPA proposes in Sec. 152.3 a definition and interpretation of 
    antimicrobial pesticide. The proposed definition is paraphrased from 
    that in section 2(mm) of FIFRA, and interprets the undefined elements. 
    Because FIFRA section 3(h) directs EPA to develop and implement special 
    procedures in its regulatory program for antimicrobial pesticides, it 
    is important that there be a well-defined and commonly understood 
    universe of products to which the statutory provisions apply. The 
    practical consequences of being included or excluded as an 
    ``antimicrobial pesticide'' are significant for both pesticide 
    producers and the Agency. FIFRA section 2(mm) defines the term 
    ``antimicrobial pesticide,'' carefully delineating its boundaries to 
    mesh with the practical implementation of section 3(h) requirements. 
    This unit discusses the definition in detail.
    
    A. General Definition
    
        Under FIFRA section 2(mm)(1)(A), an antimicrobial pesticide is 
    defined as
    
        :(A) [A pesticide that] is intended to:
        (i) disinfect, sanitize, reduce or mitigate growth or 
    development of microbiological organisms; or
        (ii) protect inanimate objects, industrial processes or systems, 
    surfaces, water, or other chemical substances from contamination, 
    fouling or deterioration caused by bacteria, viruses, fungi, 
    protozoa, algae, or slime;
    
        With respect to the scope of pests covered by the definition, 
    paragraph (i) focusses on the intended pesticidal function (disinfect, 
    sanitize, etc.) against non-specific ``microbiological organisms,'' 
    while paragraph (ii) focusses on non-specific ``protection'' provided 
    by the pesticide against specified microorganisms (bacteria, viruses, 
    etc). As a practical matter, EPA believes that the term 
    ``microbiological organisms'' in paragraph (i) should be considered to 
    include each of the specific types of microorganisms in paragraph 
    (ii)--bacteria, viruses, fungi, protozoa, and algae. Therefore, EPA 
    will consider any product intended for use against the microorganisms 
    specified in paragraph (ii) to be an antimicrobial pesticide (subject 
    to the exclusions discussed in Unit VI.B. and C.)
        Having identified the universe of substances that, based upon the 
    intended pesticidal purpose, are antimicrobial pesticides, the 
    definition goes on in paragraphs (1)(B) and (2) to exclude certain 
    pesticides from the definition of antimicrobial pesticide. These 
    exclusions may be characterized as use-based, that is, a pesticide is 
    excluded because of how or where it is used, and not because of the 
    pests or purpose of use.
    
    B. Food Use Exclusion
    
        FIFRA section 2(mm)(1)(B) excludes from ``antimicrobial pesticide'' 
    those pesticides whose intended antimicrobial use is such that residues 
    in food requiring regulation under section 408 or 409 of the FFDCA 
    might result.
    
        (B) [A pesticide that] in the intended use is exempt from, or 
    otherwise not subject to, a tolerance under section 408 of the 
    Federal Food, Drug, and Cosmetic Act (21 U.S.C. 346a and 348) or a 
    food additive regulation under section 409 of such Act.
    
        In creating this exclusion, Congress recognized that applications 
    for registration of food uses that require clearance under FFDCA 
    require extensive data and relatively complex risk assessments that 
    take longer to review. Moreover, obtaining an FFDCA clearance is a 
    formal regulatory procedure. As discussed in Unit VIII.H., FIFRA 
    section 3(h) establishes goals for completion of Agency review of an 
    application for registration. In EPA's view, Congress recognized the 
    difficulty of requiring the review timeframes for registration to 
    encompass the complexities of FFDCA clearance as well. Accordingly, EPA 
    believes that Congress intended the statutory definition to allow 
    exclusion of any antimicrobial pesticide that would require the 
    extensive clearance process of the FFDCA.
        The statutory language uses the phrases ``exempt from'' and ``not 
    subject to'' a clearance under FFDCA. The phrase ``exempt from'' is 
    clear and has meaning under FFDCA: an exemption from the requirement of 
    a tolerance is a formal regulatory determination made by EPA. 
    Exemptions from the requirement of a tolerance are found in 40 CFR part 
    180.
    
    [[Page 50678]]
    
        The phrase ``not subject to'' is not a formal determination under 
    FFDCA. Any product that bears a food use is ``subject to'' a tolerance, 
    that is, a tolerance or other clearance is required, whether that 
    tolerance has been established or not. EPA believes the statutory 
    language may be unintentionally broad in not differentiating between 
    food uses subject to an ``existing'' tolerance and those subject to a 
    ``new'' tolerance. Products and uses subject to an existing tolerance 
    do not require extensive review; only products subject to a new 
    tolerance require such review. As written, the definition excludes both 
    types of antimicrobial pesticides, although the apparent intent is to 
    exclude only those requiring the lengthy and complicated tolerance-
    setting review associated with a new clearance.
        In its discretion, EPA proposes to narrow the food use exclusion to 
    conform to what it believes is the probable intent of Congress. EPA 
    proposes to exclude from the definition of ``antimicrobial pesticide'' 
    only products bearing one or more uses for which a new clearance is 
    needed, or an amendment of an existing clearance. EPA proposes to 
    include in the definition of ``antimicrobial pesticide'' (to exclude 
    from the exclusion) product/uses ``subject to'' an existing tolerance. 
    EPA believes that this narrower policy choice, while not required, more 
    closely reflects the intent to include in the definition of 
    ``antimicrobial pesticide'' products requiring little or no review and 
    to exclude only products needing the extensive and time-consuming 
    evaluation associated with the establishment of a new or amended 
    clearance.
        An antimicrobial pesticide, then, is a product bearing only non-
    food uses, only food uses covered by an existing clearance under FFDCA, 
    or some combination of these two.
        Given the food use exclusion, it is clear that the status of an 
    antimicrobial product as an ``antimicrobial pesticide'' within the 
    meaning of FIFRA section 3(h) is not necessarily a permanent 
    designation, but may shift according to its intended use. A product 
    could be included or excluded from the definition if the intended use 
    changes. The status of a pesticide as an ``antimicrobial pesticide'' 
    becomes pertinent and can only be determined at the time of submission 
    of an application for Agency decision. At that time, EPA must determine 
    whether the pesticide application is for an antimicrobial pesticide 
    within the meaning of the statutory definition.
        The prime example of this use-dependent phenomenon is an 
    application seeking the first food use of an antimicrobial pesticide. A 
    product that heretofore has been an ``antimicrobial pesticide'' because 
    it bears only non-food uses or tolerance-covered food uses is no longer 
    an ``antimicrobial pesticide'' for purposes of EPA review and decision 
    on that first food use action. Provisions of FIFRA applying only to 
    ``antimicrobial pesticides,'' notably the review periods, would not be 
    triggered for that action. Once the food use issue is resolved or a 
    tolerance issued, such that the food use is covered by an existing 
    tolerance, the product may revert to ``antimicrobial pesticide'' status 
    for a subsequent action.
    
    C. Other Specific Exclusions
    
        FIFRA section 2(mm)(2) contains further specific exclusions to the 
    definition. These are intended to clarify that certain types of 
    products that might be considered ``antimicrobial pesticides'' because 
    they have a pesticidal effect on the defined types of microorganisms 
    are nonetheless not to be regulated as antimicrobial pesticides for 
    purposes of FIFRA section 3(h). It should be noted that certain types 
    of antimicrobial products are already excluded from regulation under 
    FIFRA, and therefore from any coverage under this proposed rule. 
    Products used against microorganisms in or on man or other living 
    animals are not pesticides because such microorganisms are not 
    ``pests'' under FIFRA section 2(t). Products intended for use against 
    microorganisms in or on man and animals are regulated solely by FDA. 
    This is not a change from longstanding FIFRA provisions.
        1. Certain wood preservatives and antifouling paints. Any product 
    that is a wood preservative or antifoulant paint, and that also bears 
    any claim for a pesticidal activity other than or in addition to those 
    specified in section 2(mm)(1) is not an antimicrobial pesticide. The 
    pesticidal activities that generally define an ``antimicrobial 
    pesticide'' include activity against any microbiological organisms, and 
    ``protection'' against the destructive effects of bacteria, viruses, 
    fungi, protozoa, algae, and slime.
        Both wood preservatives and antifoulant paints (which are used to 
    protect surfaces in contact with water such as boats) may function to 
    protect against bacteria, fungi, etc., and thus, without a specific 
    exclusion, would be deemed to be antimicrobial pesticides. However, 
    since most wood preservatives also protect against insect damage, and 
    most antifouling paints also protect against barnacles, the majority of 
    these products are not likely to be ``antimicrobial pesticides.'' As 
    discussed in Unit VIII.H., however, some wood preservative products may 
    be eligible for the review deadlines that apply to antimicrobial 
    pesticides.
        2. Agricultural fungicides. The definition of antimicrobial 
    pesticide in FIFRA section 2(mm) excludes ``agricultural fungicides.'' 
    Traditionally, the term ``fungus'' in an agricultural context has been 
    used to mean microorganisms that are pathogenic to plants. Fungi (and 
    other microorganisms) that are pathogenic to man and animals have 
    historically been treated separately because of their public health 
    implications. However, FIFRA section 2(k) defines ``fungus'' broadly to 
    include a variety of other microorganisms, including rust, smut, 
    mildew, mold, yeast, and bacteria, without specific reference to 
    whether the microorganisms are pathogenic to plants or to man and 
    animals.
        EPA intends the term ``agricultural fungicide'' to apply to all 
    products applied in or on growing crops or to soil (i.e., pre-harvest 
    application), regardless of the type of pest fungus. Although this 
    would exclude as ``antimicrobial pesticides'' products applied pre-
    harvest against microorganisms that might be pathogenic to man and 
    animals, EPA is not aware that any pesticides are currently registered 
    against human and animal pathogens on growing crops. EPA would regulate 
    such products if the need arose, but they would not be covered by 
    subpart W.
        Under this interpretation, a product intended for post-harvest 
    application against fungi (including bacteria) would not be an 
    ``agricultural fungicide.'' Significantly, however, such a product 
    would not necessarily be an ``antimicrobial pesticide'' either, since 
    the food use exclusion also comes into play. Post-harvest application 
    of fungicides or antimicrobial products to food or feed crops would run 
    afoul of the food use exclusion if a new or amended tolerance were 
    needed to cover pesticide residues. All post-harvest use antimicrobial 
    products would be subject to subpart W generally; however, not all 
    would be ``antimicrobial pesticides'' eligible for the review periods 
    in Sec. 152.457.
        3. Aquatic herbicides. Further, the definition of antimicrobial 
    pesticide excludes aquatic herbicide products. EPA interprets the term 
    aquatic herbicide to mean pesticides used in or near environmental 
    bodies of water, such as lakes, streams, or ponds, for the control of 
    algae or weeds. In contrast, a
    
    [[Page 50679]]
    
    product intended for control of algae in industrial systems or 
    processes or swimming pools would be considered an antimicrobial 
    product.
    
    D. Products Included
    
        Finally, section 2(mm)(3) lists a number of products that are 
    deemed to be antimicrobial pesticides, to ensure that they are not 
    inadvertently excluded by application of the various exclusions 
    elsewhere. These include chemical sterilants other than those excluded 
    under FIFRA section 2(u), other disinfectant products, industrial 
    microbiocides, and preservatives other than wood preservatives.
    
    VII. Current Registration Procedures for Pesticides
    
        Under FIFRA prior to FQPA, antimicrobial pesticides were not 
    singled out as a class of pesticide products requiring special 
    procedural attention. Antimicrobial pesticides were registered using 
    the same procedures and policies as other pesticide products. 
    Antifoulants, wood preservatives, and traditional antimicrobial 
    pesticides were in separate organizational units within EPA.
    
    A. Overview of Procedures
    
        A brief discussion of the registration procedures which have 
    applied to all products follows. Even though products that are 
    ``antimicrobial pesticides'' will now be subject to a more carefully 
    drawn and rigorously applied regulatory program, the basic procedures 
    for registration will continue to apply.
        1. A person seeking to register any pesticide product must submit 
    an application for registration. That application contains information 
    on the pesticide, copies of the proposed labeling of the product, and 
    data of various types supporting the registration (such as chemistry, 
    toxicology, environmental fate, ecological effects). If a food use is 
    involved, data supporting a clearance for residues in food are also 
    required, and if the product is of public health significance, efficacy 
    data must be submitted. Current regulations governing submission of 
    applications are found in 40 CFR part 152. Data requirements are 
    described in 40 CFR part 158, and labeling requirements in 40 CFR part 
    156. The tolerance-setting process is contained in 40 CFR part 180.
        2. At EPA, the application is processed in several stages, each of 
    which evaluates different elements of the application.
        a. A ``front end'' process assigns administrative numbers, checks 
    that basic elements are contained in the application, does a data check 
    for formatting purposes, and packages the application for review.
        b. The application package is directed to the appropriate review 
    Division and thence to a Product Management (PM) team. Until recently, 
    two Divisions, the Registration Division and the Biopesticides and 
    Pollution Prevention Division, were the regulatory Divisions which 
    reviewed all applications. Antimicrobial pesticide applications were 
    processed within one branch, and antifoulants and wood preservatives 
    were located in a different branch, both in the Registration Division. 
    EPA has established a separate Antimicrobials Division (AD) to help 
    focus its regulatory management of these products, and antifoulants and 
    most wood preservatives are also now assigned to this Division.
        c. The PM team enters the application into a tracking system, 
    reviews product labeling and data compensation elements, and determines 
    whether a scientific review is needed. Every application for new 
    registration contains some data; the amount and type of data vary 
    depending on the type of product, its composition and uses. Even 
    applications without new data often require scientific consultation to 
    determine the relevance and adequacy of existing data to support the 
    application.
        d. If a scientific review is needed, the PM team sends the 
    application and data to various scientific reviewers. These reviews are 
    generally conducted in parallel, although certain assessments must 
    await the results of other reviews (for example, ecological effects 
    risk assessment may depend upon the environmental fate profile of the 
    chemical).
        3. Upon completion of all reviews, the PM team consolidates review 
    recommendations and decisions and determines whether the product can be 
    registered. If it can, EPA issues a registration, approves the labeling 
    (often with required modifications), and notifies the applicant. If the 
    application cannot be approved, the PM notifies the applicant of 
    deficiencies (data, labeling, administrative) that must be corrected 
    before proceeding.
        Once issued, a registration may be amended by submission of an 
    application for amendment, which undergoes a similar review process as 
    outlined above. The significant difference is that many amendments are 
    administrative, or require no scientific review, and thus entail a less 
    intensive and time-consuming process. Often amendments can be handled 
    entirely within a PM team. Some minor modifications to registration can 
    be accomplished by notification; these are modifications EPA has 
    determined have no potential for adverse effects. Notifications require 
    the most minimal review, primarily to ensure compliance with pre-
    existing Agency policies or guidance.
    
    B. Volume of Work
    
        Typically, applications for new registration comprise about one-
    third of the applications processed by the Agency, but require more 
    time and resources per application because of the scientific review 
    involved. Applications for registration of new chemicals and major new 
    uses require the most resources, but are relatively few in number. For 
    sheer numbers, the bulk of registration actions are (and likely will 
    continue to be) amendments to existing registrations that require no 
    scientific review (so-called ``fast track'' amendments). In FY 1997, 
    ending September 1997, EPA received a total of 635 actions related to 
    new applications for registration of pesticides assigned to AD, 
    including 11 high-resource new chemicals. In addition, there were 1,189 
    actions related to amendments to existing registrations, including 61 
    high-resource new uses. The number of ``actions'' includes both the 
    initial submission of applications for new and amended registration and 
    resubmissions of information after EPA has notified the applicant that 
    the application is deficient.
        Finally, there were 506 notifications for antimicrobial products, 
    which under FIFRA section 3(c)(9) must be reviewed and a decision 
    issued within 30 days of receipt. While these require minimal review, 
    the large volume coupled with the short review time requires dedicated 
    resources.
    
    C. Review Times
    
        As with any complex process, the speed at which an application can 
    be reviewed and a decision made depends upon many things, some within 
    the control of the Agency, others dependent upon the applicant. FIFRA 
    prescribes in section 3(c)(3) that an application decision be reached 
    ``as expeditiously as possible.'' Until modified by FQPA, FIFRA 
    contained only a single statutory decision deadline of 90 days, for so-
    called ``fast-track'' applications--those which require no review of 
    scientific data. This review time is predicated upon receipt of a 
    ``complete'' application. EPA is not required to review and reach a 
    decision on a fast-track application until it is deemed to be complete 
    (however, EPA must determine whether such an application
    
    [[Page 50680]]
    
    is complete within 45 days after receipt).
        ``Fast-track'' deadlines continue to apply to all products, 
    including antimicrobial pesticides. For antimicrobial pesticides, 
    however, FIFRA as modified by FQPA imposes additional statutory review 
    periods.
    
    D. Non-Regulatory Guidance Documents
    
        EPA uses detailed guidance documents to amplify, clarify, and 
    interpret its regulations in areas such as data and labeling 
    development and review, process changes, and applicant 
    responsibilities. EPA has developed a number of documents, which are 
    available to applicants and registrants, to elaborate on the general 
    regulations. In particular:
        1. A guidance document called simply the ``Blue Book'' provides 
    specific details about the application process.
        2. The Labeling Manual contains guidance for developing labeling 
    which complies with FIFRA and EPA regulations.
        3. The Pesticide Assessment Guidelines describe test methods, 
    standards, and data reporting requirements used to satisfy data 
    requirements.
        4. Standard Evaluation Procedures describe how EPA will review and 
    evaluate each type of study submitted in support of registration.
        5. EPA uses direct notice to registrants (PR Notices) to inform 
    them of procedural changes, to clarify and interpret its regulations in 
    specific circumstances, and for general information purposes.
        All of these will continue to apply to antimicrobial pesticides. 
    Given the special attention FIFRA now focusses on antimicrobial 
    products, EPA may develop specific guidance documents for antimicrobial 
    pesticides that would augment or replace existing guidance.
    
    VIII. Proposed Antimicrobial Procedures
    
        This unit discusses in detail the proposed procedural regulations 
    applicable to antimicrobial products. Proposed changes that apply to 
    all pesticides are discussed in later units of this preamble.
    
    A. Organization of Proposed Subpart W and Relationship to Current 
    Regulations
    
        40 CFR part 152 currently contains regulations pertaining to the 
    registration of pesticide products, including antimicrobial pesticides. 
    Part 152 contains appropriate definitions and criteria for determining 
    whether a product is a pesticide that must be registered (subpart A); 
    exemptions from FIFRA requirements (subpart B); procedures for applying 
    for registration (subpart C); data compensation procedures (subpart E); 
    the Agency's review of an application (subpart F); fees for 
    applications (subpart U) (currently suspended), and criteria and 
    procedures for classifying a pesticide for restricted use (subpart I). 
    Most of these provisions are unaffected by changes in FIFRA that target 
    antimicrobial program reform measures, and will continue to apply to 
    antimicrobial products as well as other pesticides.
        However, FIFRA section 3(h)(3)(A) requires that EPA propose 
    procedural regulations focussing on antimicrobial pesticides. Because 
    the statutory reform measures are designed to implement specific goals 
    directed at antimicrobial products only, EPA proposes to create an 
    entirely separate subpart devoted to antimicrobial registration 
    procedures. Proposed new subpart W, entitled ``Registration of 
    Antimicrobial Products,'' would be a freestanding subpart describing 
    the application and Agency review procedures mandated by FIFRA section 
    3(h).
        1. Relationship of subpart W to other subparts in part 152. Subpart 
    W would supersede subpart C of current part 152 for antimicrobial 
    products only; subpart C would continue to apply to all other products.
        In addition, subpart W--for antimicrobial products only--would 
    supersede certain individual sections of subpart F--Agency Review of 
    Applications; subpart F would continue to apply to all other products. 
    Specifically, the following sections would be superseded:
        a. Sec. 152.104, Completeness of applications. Completeness of 
    applications covered by subpart W is contained in Sec. 152.450, 
    Contents of application.
        b. Sec. 152.110, Time for Agency review. Review periods for 
    applications covered by subpart W are contained in Sec. 152.457, Review 
    period for applications.
        c. Sec. 152.115, Conditions of registration. Conditions of 
    registration for products covered by subpart W are contained in 
    Sec. 152.459, Terms and conditions of registration.
        d. Sec. 152.117, Notification to applicant. Notification of Agency 
    decision on an application is contained in Sec. 152.455, Action on 
    applications.
        e. Sec. 152.118, Denial of application. Denial of an application 
    covered by subpart W is also included in Sec. 152.455, Action on 
    applications, although the procedures for denial in Sec. 152.118 are 
    cross-referenced in Sec. 152.455.
        As described in Sec. 152.440, all other subparts of part 152 would 
    continue to apply to products covered by subpart W and other 
    pesticides. Some minor modifications are proposed to current Sec. 152.1 
    to properly refer to the antimicrobial subpart. If subpart W and 
    subpart F conflict for an antimicrobial product or application, 
    Sec. 152.440 states that subpart W would take precedence.
        2. Requirements duplicated in subpart C and subpart W. To be 
    comprehensive, avoid confusion for users, and avoid cross-referencing 
    unnecessarily, EPA has repeated in subpart W certain elements of its 
    current registration regulations from subpart C. In so doing, EPA has 
    made minor editorial changes not requiring proposal for clarity and 
    organization. EPA has captured the content of the following sections in 
    subpart W, and is not requesting comment at this time:
        a. Sec. 152.40, Who may apply, which also appears as new 
    Sec. 152.443.
        b. Sec. 152.42, Application for new registration, which has been 
    incorporated into new Sec. 152.443.
        c. Sec. 152.43, Alternate formulations, which also appears as 
    Sec. 152.444, unchanged.
        d. Sec. 152.44, Application for amended registration, which is also 
    incorporated into new Sec. 152.443.
        EPA has incorporated into proposed Sec. 152.443(e) a general 
    provision for certification programs at the Agency's discretion and 
    direction. Current regulations in Sec. 152.44(b)(2) allow a 
    certification submission, in the Agency's discretion, which EPA has 
    typically used only for Agency-directed actions. EPA has not to date 
    expanded the certification option to a class of actions submitted on 
    the applicant's initiative. EPA believes that it may implement 
    certification programs administratively without regulations. 
    Nonetheless, in light of the statutory provision requiring 
    consideration of a certification process, EPA proposes a broader, but 
    still discretionary, use of certification programs. Under today's 
    proposal, EPA could identify elements of an application that the Agency 
    believes are amenable to a certification mechanism. EPA would issue a 
    guidance document (typically a notice to registrants) that would detail 
    how a certification program would be used.
    
    B. Applicability of Subpart W
    
        The applicability of subpart W is governed by the statutory mandate 
    of FIFRA section 3(h) in the first instance. However, because of 
    differences in scope between the statutory mandate and the Agency's 
    administration of the antimicrobial program, EPA proposes a
    
    [[Page 50681]]
    
    broader applicability than is provided for by the statute. This unit 
    explains why certain products would be covered by subpart W and others 
    would not be.
        1. Antimicrobial pesticides and food/feed use antimicrobial 
    products are covered by subpart W. Although this proposal reflects the 
    mandate of FIFRA to address ``antimicrobial pesticides,'' EPA has 
    chosen to cover a broader range of antimicrobial products than 
    mandated. It makes sense for these procedural regulations to mesh as 
    closely as possible with the Agency's organization and administration 
    of the antimicrobial program, so as not to cause confusion either 
    within the regulated community or within EPA itself. EPA has created an 
    Antimicrobial Division within the Office of Pesticide Programs, whose 
    responsibilities extend to all antimicrobial products, not just those 
    defined as ``antimicrobial pesticides.''
        Accordingly, EPA proposes that subpart W would apply to both 
    ``antimicrobial pesticides,'' as defined by FIFRA section 2(mm) and 
    antimicrobial products that are food/feed use pesticides, but are not 
    defined as ``antimicrobial pesticides'' by FIFRA section 2(mm). 
    Virtually all products in these two categories are processed within the 
    Antimicrobial Division. The procedures and requirements of subpart W 
    would be applied equally to these two categories of products (with the 
    exception of review periods).
        2. Wood preservatives and antifouling products are not covered by 
    subpart W. This subpart would not apply to any product that is neither 
    an ``antimicrobial pesticide'' as defined by FIFRA nor a food/feed use 
    antimicrobial product. Inclusion in this subpart would complicate the 
    registration process for products not processed in the Antimicrobials 
    Division, which are subject to the registration procedures of subpart 
    C.
        The status of wood preservatives and antifoulant paints is 
    complicated under FIFRA. FIFRA is very specific in defining certain 
    types of products as antimicrobial pesticides and excluding other, 
    similar products, depending upon the type of claims made for the 
    product. A wood preservative or antifoulant paint that makes only an 
    antimicrobial pesticidal claim is an ``antimicrobial pesticide'' and 
    would be covered by subpart W as an antimicrobial pesticide. By 
    contrast, any multi-claim wood preservative or antifoulant paint is not 
    an ``antimicrobial pesticide'' and would not be covered by subpart W. 
    As a practical matter, because most antifoulant paints assert non-
    antimicrobial barnacle claims, they would not be covered by subpart W. 
    Likewise, many wood preservatives make insecticidal or fungicidal 
    claims and would not be covered by subpart W.
        Under FIFRA section 3(h)(3)(E), certain wood preservative products 
    that would not be covered by subpart W may nonetheless be eligible for 
    the same review periods as antimicrobial pesticides that are covered by 
    subpart W (see Unit VIII.H. for a full discussion of this provision). 
    EPA's responsibility for wood preservative products that qualify under 
    section 3(h)(3)(E) is fulfilled by ensuring that the statutory review 
    period is met. EPA need not, and does not propose to, make subpart W 
    apply to these products merely to implement the statutory review 
    periods.
        Because the status of wood preservatives and antifoulant paints is 
    complex, EPA is providing in Table 1 below a summary of the status of 
    these products. The table breaks down wood preservatives and 
    antifoulant paints by type of claim (or combination of claims). Column 
    1 of the table lists the claim or combination of claims possible; 
    Columns 2, 3, and 4 answer the questions posed at the top of each 
    column.

                                                                                                 Is this product
                                              Is this product an      Will this product be         eligible for
                                               ``antimicrobial          subject to this        statutorily-required
                                                 pesticide''?              proposal?             review periods?
    ----------------------------------------------------------------------------------------------------------------
    Wood Preservatives
    Insecticide claims only                No                       No                       No
    ----------------------------------------------------------------------------------------------------------------
    Fungicide claims only                  No                       No                       No
    ----------------------------------------------------------------------------------------------------------------
    Antimicrobial claims only              Yes                      Yes                      Yes
    ----------------------------------------------------------------------------------------------------------------
    Fungicide and insecticide claims       No                       No                       No
    ----------------------------------------------------------------------------------------------------------------
    Antimicrobial and insecticide claims   No                       No                       Yes
    ----------------------------------------------------------------------------------------------------------------
    Antimicrobial and fungicide claims     No                       No                       Yes
    ----------------------------------------------------------------------------------------------------------------
    Antimicrobial, insecticide and         No                       No                       Yes
     fungicide claims
    ----------------------------------------------------------------------------------------------------------------
    Antifoulant Paints
    Insecticide claims (barnacles) only    No                       No                       No
    ----------------------------------------------------------------------------------------------------------------
    Antimicrobial claims only              Yes                      Yes                      Yes
    ----------------------------------------------------------------------------------------------------------------
    Antimicrobial and insecticide claims   No                       No                       No
    ----------------------------------------------------------------------------------------------------------------
    
        3. Applicability is not dependent on where a product application is 
    processed. EPA has chosen to extend the proposal to food/feed use 
    antimicrobials for practical organizational reasons. However, EPA 
    emphasizes that where a product application is reviewed does not in any 
    way determine whether subpart W applies. For example, the Antimicrobial 
    Division currently reviews most antifoulant products, that for the most 
    part are not covered by subpart W. The Antimicrobial Division also 
    reviews those wood preservatives that do not make insecticidal claims, 
    some of which are covered by subpart W. This allocation of products may 
    change based upon workload and resource needs.
        EPA may, in its discretion and for its convenience, choose to treat 
    products that are not covered by subpart W as if
    
    [[Page 50682]]
    
    they were covered. For example, EPA currently reviews applications for 
    non-covered products within the review periods of Sec. 152.457, but, 
    except for the narrow class of wood preservatives discussed above, the 
    Agency is not required to do so, and would not be subject to any 
    consequences if it failed to meet a review period.
    
    C. Definitions
    
        Section 152.442 contains definitions that apply to subpart W. 
    Relatively few definitions are needed here, since most terms are 
    defined elsewhere, either in FIFRA itself or in part 152. Terms 
    pertaining to antimicrobial levels of activity (e.g., sterilant, 
    disinfectant) are defined in subpart W of part 156, because they are 
    used in conjunction with labeling and not with registration procedures. 
    Comments are solicited on any additional terms that should be defined 
    in subpart W to inform or clarify the subpart.
        Proposed Sec. 152.442 defines the following terms:
        1. The term ``clearance'' is proposed to refer to all types of 
    clearances required under a regulatory authority other than FIFRA 
    before a product may be marketed. The term encompasses food tolerances, 
    exemptions and food additive regulations under FFDCA section 408 and 
    409, and FDA clearances for medical devices under FFDCA section 510.
        2. The term ``complete application'' is the general definition 
    describing an application that may be placed into formal review. A 
    complete application is one that contains all elements described by 
    Sec. 152.450, but not necessarily all information required for 
    approving a registration or amendment.
        3. The terms ``major new use,'' ``substantive amendment,'' and 
    ``minor amendment'' are proposed as concise terms for application types 
    defined in rather longer phrases in the statute.
    
    D. Types of Applications
    
        1. What the statute requires. FIFRA section 3(h)(2) establishes 
    review period goals for antimicrobial applications, shown in Table 2 
    below, and requires in section 3(h)(3) that EPA differentiate in its 
    regulations the types of review undertaken for antimicrobial 
    pesticides. As discussed in Unit IV.C., EPA intends that defining these 
    application types in this proposal, coupled with EPA's part 158 
    proposal, will serve to adequately differentiate the types of review 
    undertaken by the Agency. EPA proposes in Sec. 152.445 to define 
    application types that correspond to the statutory review period goals 
    prescribed in the statute. The categories EPA proposes are discussed in 
    this unit.

        2. Applications requiring FFDCA clearance. The review periods for 
    which application types must be described apply only to antimicrobial 
    pesticides as defined in FIFRA section 2(mm). That definition excludes 
    food/feed use products that require a clearance under FFDCA. Before 
    assigning an application to a category having a review period, EPA must 
    first exclude any application for a food/feed use that requires a new 
    or revised clearance under FFDCA.
        All other antimicrobial pesticide applications fall into one of the 
    categories, described in proposed Sec. 152.445(b) for new registrations 
    and proposed 152.445(c) for amendments to existing products.
        3. Current application categories. Currently, EPA does not define 
    types of applications for registration by regulation, but has a 
    detailed tracking system (the Pesticide Regulatory Action Tracking 
    System or PRATS) for actions of all types flowing through the pesticide 
    review process. The system works by assigning action codes to each type 
    of action for purposes of PRATS tracking, reporting and process 
    management; the action code definitions are detailed and do not 
    correlate exactly with the six described in the statute. The PRATS 
    system describes application types and assigns target review periods 
    based on features that are not addressed by the general descriptions in 
    the statute, including:
        a. The applicant's method of support for the application 
    (eligibility for the formulator's exemption, for example).
        b. The amounts and types of data that require scientific review 
    (product chemistry or confirmatory efficacy data, for example, require 
    minimal review, while toxicology studies require considerable review 
    time).
        c. In the case of amendments, what aspect of the registration is 
    being amended (composition, labeling).
        d. Whether the application is an initial submission or a 
    resubmission following a rejection of an initial application.
        Moreover, combinations of registration actions (for example, a 
    change in composition and labeling simultaneously, each with supporting 
    data requirements) complicate EPA's task of describing a categorization 
    scheme in simple terms.
        It would be costly and inefficient for EPA to develop and manage 
    separate tracking systems for antimicrobial decisions and other 
    registration decisions. Nor does it make sense to do so. If EPA is to 
    successfully manage the review process and track review periods for 
    antimicrobial applications, it must use its existing tracking system. 
    Accordingly, EPA's approach to defining types of antimicrobial 
    applications was to crosswalk the types of applications defined by the 
    statute with the descriptors used in PRATS.
    
    [[Page 50683]]
    
    EPA first sorted the categories of actions in PRATS and identified 
    those that should be included in one of the six statutory categories. 
    EPA then fleshed out the statutory descriptions using the greater 
    detail of PRATS action code descriptions for purposes of this proposal. 
    The results of this approach are presented in proposed Sec. 152.445.
        4. Terms defined for this proposal. EPA proposes to define more 
    concise terms than the statutory ones for the purposes of this proposed 
    rule. EPA proposes the following terms: (1) The term ``major new use'' 
    for the statutory term ``new antimicrobial use of a registered active 
    ingredient''; (2) the term ``substantive amendment'' for the statutory 
    term ``amendment to an antimicrobial registration that requires 
    sceintific review of data''; and (3) the term ``minor amendment'' for 
    the statutory term ``amendment to an antimicrobial product that does 
    not require scientific review of data.''
        5. Single category. Because each antimicrobial pesticide 
    application type will have a prescribed review period under FIFRA, and 
    EPA's failure to issue a decision within that review period will be 
    judicially reviewable, each application must be assigned to a single 
    application category. Ideally, the applicant and EPA would have a 
    common understanding of the designation of an application to avoid 
    disputes over the review period. In all situations, the application 
    categories in proposed Sec. 152.445 are discrete, that is, there is 
    only one possible application type that logically should apply. An 
    application either is for a new registration or is an amendment to an 
    existing registration. Beyond that broad division, the categories may 
    be less well understood and subject to disagreement. Under proposed 
    Sec. 152.445(a), EPA would determine the appropriate category.
        There is one situation in which the statutorily designated review 
    period cuts across the application types as defined in the proposal. 
    The Act sets a review period of 270 days for a ``new antimicrobial use 
    of a registered active ingredient'' or ``major new use.'' Proposed 
    Sec. 152.445 defines application types in the first instance according 
    to whether they are submitted to EPA as applications for new 
    registration or amended registration. In the construct of the proposal, 
    therefore, an application for a ``major new use'' may be either an 
    application for new registration that includes a major new use, or an 
    application for amended registration to add a major new use. 
    Accordingly, both Sec. 152.445(b) and (c) include a separate category 
    for ``major new use. In both cases, the review period would be 270 
    days.
        6. Applications for new registration--a. A product containing a new 
    active ingredient. Products containing new active ingredients are a 
    well-understood category. An application that proposes the registration 
    of an active ingredient that has never before been registered falls 
    into this category. A product containing a new active ingredient 
    typically requires review of considerably more data than one containing 
    already registered active ingredients.
        b. A product bearing a major new use. This category consists of an 
    application for new registration of a product bearing a major new use. 
    A major new use is any use that is not registered for one or more of 
    the active ingredients in a product. Typically a major new use would 
    involve a significantly different pattern of use that changes or 
    increases the exposures to the active ingredient, such that substantial 
    amounts of new data are required to evaluate the different or 
    incremental risks presented. This definition is comparable to that in 
    Sec. 152.3 for ``new use'' for non-antimicrobial products.
        EPA intends in its part 158 proposal to categorize all 
    antimicrobial uses into one of the following 12 use categories. All 
    currently registered antimicrobial use patterns are included in one of 
    these larger use classifications for data requirement purposes, but EPA 
    has not to date classified the existing use patterns in this organized 
    fashion.
         Agricultural premises and equipment.
         Food handling/storage establishments premises and 
    equipment.
         Commercial, institutional, and industrial premises and 
    equipment.
         Residential and public access premises.
         Medical premises and equipment.
         Human drinking water systems.
         Materials preservatives.
         Industrial processes and water systems.
         Antifouling coatings.
         Wood preservatives.
         Swimming pools.
         Aquatic areas.
    Some categories would be further divided into subcategories. 
    Subcategories would generally be defined on the basis of similar 
    exposures and data requirements. Examples of significant use/exposure 
    differentials among use categories and subcategories are food/non-food 
    use and indoor/outdoor use or exposure.
        Using these categories and subcategories of antimicrobial use 
    patterns, EPA would regard as a major new use of an antimicrobial 
    active ingredient any use in a different use category or subcategory 
    from currently registered uses for that active ingredient. As an 
    example, an active ingredient is registered with uses in the category 
    of ``Materials Preservatives'' and subcategory ``Indoor non-food 
    uses.'' If a registrant proposed a new use either in that same category 
    for an ``Indoor food use'' (a different subcategory), or in the 
    different category of ``Residential and Public Access Premises,'' that 
    application would be a major new use of that active ingredient.
        c. A product that is identical to an existing product. For clarity, 
    this proposal separates ``identical'' and ``substantially similar'' 
    products into two categories, even though they have the same review 
    period. Applications for end use products of these types are generally 
    indistinguishable from the so-called ``fast-track'' applications of 
    FIFRA section 3(c)(3).
        Identical products are those that have an identical composition to 
    another registered product and bear identical use patterns. Both active 
    and inert ingredients must be identical and in exactly the same 
    proportion as the existing product. In the universe of antimicrobial 
    products, ``identical'' products include products that are formulated 
    by one company and simply repackaged by another company. These so-
    called ``repacks'' must be separately registered by the repackager. 
    Identical products also include those that are actually formulated by a 
    second producer based upon specifications provided by another 
    registrant. The significant difference between these two types of 
    identical products is that ``repacks'' require virtually no data for 
    registration, while those that are produced separately require certain 
    minimal ``bridging'' data to ensure that they are actually identical in 
    composition and efficacy.
        Identical use patterns mean that the label does not deviate in 
    terms of organisms controlled, use sites, or directions for use. An 
    applicant's product may have fewer (but identical) claims than another 
    registered product and still be an ``identical'' product, but may not 
    have different or expanded claims.
        d. A product that is substantially similar to an existing product. 
    Substantially similar products are those that are permitted to have 
    minor differences in three areas--composition, use pattern, or method 
    of data support--from another registered product. When evaluated 
    against another identified registered product, a ``substantially
    
    [[Page 50684]]
    
    similar'' product must have the same active ingredients as the claimed 
    similar product, in substantially the same proportion. The inert 
    ingredients must also be substantially similar in chemical composition 
    and functionality to the claimed similar product. For example, 
    emulsifiers, fillers, solvents, propellants, etc., in the applicant's 
    product must have similar counterparts in the cited registered product 
    so EPA can reasonably conclude that both formulated products will have 
    essentially the same chemical and physical characteristics and toxicity 
    profile. Because substantial similarity may depend on the 
    characteristics of the individual products or the active and inert 
    ingredients, decisions on similarity would be made on a case-by-case 
    basis.
        Substantially similar use means that the product bears a use 
    pattern similar to the claimed product. Again, fewer use patterns do 
    not make the product dissimilar, but adding or changing use patterns 
    would exclude the applicant's product from treatment as a substantially 
    similar product. A use pattern is a claim for control of a specified 
    organism on a specified site under specified conditions of use. With 
    respect to public health products, for which efficacy considerations 
    are paramount, use sites must be carefully considered in relation to 
    the pest organism, and small formulation changes or variations in use 
    directions can mean the difference between an efficacious product and a 
    non-efficacious product. For this reason, ``substantially similar'' use 
    patterns for public health products would be limited to identical 
    organisms on both products. For non-public health products, 
    substantially similar use patterns could involve organisms that are 
    similar but not identical.
        A similar method of data support means that the applicant is using 
    methods of data support that do not require EPA to evaluate data (other 
    than product chemistry data) to review the application. As a practical 
    matter, this means that the applicant is either citing all required 
    studies or requesting a waiver of required studies. Many antimicrobial 
    products must be supported by efficacy data of some sort. Such products 
    are not substantially similar even if they are similar in composition 
    and use pattern to another product, because the submitted efficacy data 
    must be reviewed by EPA. Such products would be considered ``other'' 
    products.
        e. ``Other'' products. All applications for new registration other 
    than new chemicals, identical or substantially similar products, or 
    those bearing a major new use, would be assigned to the ``other'' 
    category. These are products which have significant differences in 
    composition, uses, method of data support or labeling. Proposed 
    Sec. 152.445(b)(5) provides examples of applications that would be 
    categorized as ``other'' new applications, but is not comprehensive or 
    explicit, since it is essentially a default category of application. If 
    a new application cannot readily be categorized either as a ``new 
    active ingredient'' or as an ``identical'' or ``substantially similar'' 
    application, it would routinely be placed in this category.
        7. Applications for amendment. Applications for amendment to an 
    existing registration are categorized in much the same fashion as new 
    applications, that is, by defining the ends of the review spectrum, and 
    placing all amendments not clearly delineated into a middle category. 
    EPA therefore defines in this proposal three categories of amendments.
        a. Amendment to add a major new use. As noted earlier, a major new 
    use may be presented to EPA in the form of a new registration or an 
    amendment. This category is for amendments to add a major new use to an 
    existing registration (as opposed to a new registration that bears a 
    major new use). ``Major new use'' would be the same as described 
    earlier.
        b. Minor amendment. At the other end of the amendment spectrum, EPA 
    proposes an application category termed ``minor amendment.'' This 
    category is intended to parallel the ``identical or substantially 
    similar'' category for new applications, and is also identical to the 
    statutorily-defined ``fast-track'' provision of FIFRA section 3(c)(3). 
    In no case would a minor amendment require the review of any data. The 
    examples in proposed Sec. 152.445(c)(3) list minor amendments not in 
    terms of the actual registration changes that might be proposed, but in 
    terms of the nature of the evaluation that EPA must do. EPA does not 
    believe that this proposal can, or needs to, describe all the possible 
    types of ``minor amendments.''
        The following are some characteristics of a minor amendment:
         The evaluation can be conducted entirely within a Product 
    Manager team, without any scientific consultation.
         The decision relies only on non-technical, non-scientific 
    information readily at hand.
         The decision requires only regulatory or administrative 
    judgments, not scientific ones.
         The decision applies existing policy, evaluates adherence 
    to existing policy, or ensures consistency among decisions.
        The evaluation consists of simple comparisons among products.
         The evaluation requires no separate documentation (such as 
    a scientific review) beyond the decision itself.
        c. Substantive amendment. EPA proposes a category termed 
    ``substantive'' amendments. This type of application would parallel the 
    ``other'' category of new registrations, and would encompass all 
    amendments that are neither ``major new uses'' nor ``minor'' 
    amendments. This category consists of amendments that require the 
    review of any scientific data.
        Most changes in label precautionary statements or use directions 
    are included in this category, as well as many changes in product 
    composition. Inclusion of such a wide variety of amendments in this 
    category simply reflects the fact that these changes require the review 
    of some data. The data may consist solely of bridging or confirmatory 
    chemistry, toxicity, or efficacy data to demonstrate that the product 
    and its uses, as modified, would not significantly increase risks, or 
    that the product as modified remains efficacious. Moreover, the review 
    may be a cursory evaluation of existing data to determine that the 
    amendment is adequately supported. Nonetheless, the defining 
    characteristic of a substantive amendment is the need to review some 
    data, either submitted by the applicant or cited from Agency files.
        This category is the only one in the statute that carries a range 
    of review periods (90 to 180 days), a provision that recognizes the 
    variety of amendments that can conceivably be proposed to a 
    registration. Arguably, the inclusion of a range of review periods 
    suggests that there are gradations of application types within this 
    range--applications that are relatively less complex that could fall at 
    the short end of the review period (90 to 120 days) and others that 
    require the full 180 days. Under this interpretation, EPA could be 
    expected to establish by regulation subcategories of application to 
    which a specific review period within the 90- to 180-day range would 
    apply. Equally consistent with the statute would be an interpretation 
    holding that the range was included simply to allow EPA the flexibility 
    to deal on a case-by case basis with the wide variety of amendments 
    covered by this category, and that no further differentiation or other 
    regulatory treatment is required.
        EPA adheres to the latter view. EPA does not believe that it is 
    statutorily obligated to establish subcategories of 90- to 180-day 
    substantive
    
    [[Page 50685]]
    
    amendments. EPA has not discerned any great benefit to the Agency in 
    doing so, especially by regulation, while noting a number of 
    disadvantages. A proliferation of categories in itself creates 
    administrative burdens for EPA in tracking applications. The more 
    categories that are created--each having its own description against 
    which applications must be judged and a distinct review period--the 
    more time it takes EPA generally to administer a tracking system and 
    ensure that review periods are met. Likewise, the more EPA is bound by 
    regulatory categories and review periods, the less flexibility the 
    Agency has to respond to changing review needs or critical priorities 
    without running afoul of its regulations. EPA is not precluded from 
    adopting administrative subcategories if it does not choose to adopt 
    regulatory ones. Moreover, it is not clear that there would be 
    significant benefits to applicants in gaining a decision 30 to 60 days 
    earlier that would justify the additional administrative burden for 
    EPA. Accordingly, EPA is not proposing any specific subcategories. 
    Under today's proposal, all substantive amendments would be afforded 
    the same review period, that is, a maximum of 180 days.
        In its stakeholder meetings over the past year, however, industry 
    representatives requested that EPA solicit comment on whether 
    subcategories should be established. Suggestions from the Chemical 
    Specialties Manufacturers' Association (CSMA) included the following, 
    all of which would be classified as substantive amendments:
        1. Amendment with data to add a ``me-too'' use that requires full 
    toxicology and efficacy review.
        2. Amendment with data to change a formulation that requires full 
    toxicology and efficacy review.
        3. Amendment with data to modify a label requiring a toxicology or 
    efficacy review.
        4. Amendment without data to modify a label which requires a 
    toxicology or efficacy review.
        EPA solicits comments on these and other sub-categorizations and 
    review periods. Commenters should consider the following factors 
    important to EPA's decision:
         A suggested category must be capable of unambiguous 
    description. EPA would likely not consider a category of uncertain 
    description that could be subject to dispute between applicants and the 
    Agency.
         A suggested category must be meaningful in terms of both 
    numbers of applications likely to fall in that category and in the 
    suggested shorter review period. A category that includes relatively 
    few amendments would be equally unsatisfactory as one that includes too 
    many amendments. A suggested review period with less than a 30-day 
    decrement (180 to 160 days for example) would likely not be considered 
    meaningful. Nor would EPA likely adopt a category with a suggested 
    review period of 90 days, since there would then be no distinction 
    between that subcategory of substantive amendment and a minor 
    amendment.
         A suggested category must be comprised of amendments that 
    can be reviewed within a review period of less than 180 days without 
    jeopardizing EPA's ability to meet other review periods. EPA is 
    committed to making decisions on applications as rapidly as possible, 
    and currently is meeting the review period goal of 180 days 
    consistently for all substantive amendments, but without consideration 
    of subcategories.
        If commenters persuade EPA that additional subcategories should be 
    established, and that the benefits of less than 180-day decisions 
    outweigh the added administrative burdens (bearing in mind that the 
    Agency has limited resources and that additional administrative burdens 
    mean fewer resources for reviewing applications), EPA may in the final 
    rule adopt one or more subcategories of substantive amendments that 
    would refine the review period within the 90- to 180-day range. EPA 
    will not consider subcategories of any types of applications other than 
    substantive amendments.
    
    E. Consultations During the Application Process
    
        Because EPA is required to process complete applications for 
    registration within judicially reviewable timeframes, it is critical 
    that applications and data be complete and conform to Agency 
    requirements, and, as much as possible, that applicants and the Agency 
    have a common understanding of requirements and expectations about the 
    process and its outcomes.
        EPA recognizes that the registration process can be complicated for 
    persons who are unfamiliar with FIFRA and its requirements; even for 
    those who deal routinely with the Agency, keeping up with new policies 
    and procedures can be challenging.
        In the past, deficiencies in applications or data have been 
    resolved during or after the review process, either informally, for 
    example with a telephone call for a minor problem, or formally, by 
    rejecting an application with significant deficiencies. The current 
    review process has tended to encourage consultation only after an 
    application has been rejected, when EPA can explain both the results of 
    its review and what an applicant needs to do to correct deficiencies. 
    Pre-submission consultation has not typically been the case with 
    antimicrobial products.
        With the completeness of an application at stake for an applicant, 
    and strict review periods in place for EPA, it makes sense for both to 
    consult as much as is practicable and as early as possible. 
    Misunderstandings about requirements and expectations may lead to 
    needless determinations of incompleteness or denial for the applicant, 
    while impeding EPA's ability to reach decisions in a timely fashion as 
    required by the statute.
        EPA encourages consultation with the Agency on any application 
    prior to a determination of completeness. However, the majority of 
    antimicrobial applications are for so-called ``me-too'' products and 
    uses, those which are identical or substantially similar to others 
    already registered. Such applications are relatively easy to submit 
    correctly, seldom raise new or controversial issues, and should not 
    routinely require specific consultation. Once an application has been 
    determined to be complete, and has been placed in review, the applicant 
    should not need or expect to consult the Agency until the end of the 
    appropriate review period (which for ``me-too'' products is only 90 
    days), or until EPA notifies the applicant of a deficiency.
        However, EPA has identified two areas where it believes advance 
    consultation is essential to the submission of a complete application, 
    and proposes in Sec. 152.447 to require pre-submission consultation. 
    The first is applications for new chemicals and major new uses. These 
    consultations, which are common for agricultural chemicals but rare for 
    antimicrobial chemicals, help the applicant and the Agency agree upon 
    data requirements, data waivers, or issues that typically arise for new 
    chemicals and major new uses (such as food use status).
        In addition, EPA proposes to require pre-submission consultation 
    whenever an efficacy test protocol or method must be approved by the 
    Agency either because there is no protocol or because the applicant 
    wishes to modify an exising protocol.
        The regulation does not prescribe how consultation is to be 
    accomplished. There is no requirement that a required consultation 
    occur in a meeting; a conference call, letter, or other form of
    
    [[Page 50686]]
    
    communication may be sufficient, depending on the nature of the new 
    chemical, new use, or protocol approval needs. However, proposed 
    Sec. 152.447 emphasizes that any regulatory determinations must be in 
    writing. EPA expects the applicant to follow up any consultation with a 
    summary of any decisions so that EPA may confirm them in writing. 
    Proposed Sec. 152.450 would require written documentation of a 
    consultation describing the substance of the consultation to be 
    submitted with the application to verify that the consultation took 
    place as required.
        In turn, EPA would commit to adhere to the decisions agreed upon in 
    a pre-submission consultation unless the circumstances of the 
    application change, its determinations were in error, or a question of 
    adverse effects arises.
    
    F. Contents of Applications
    
        1. What the statute requires. FIFRA section 3(h) requires formal 
    Agency review only upon submission of a ``complete'' application, and 
    requires that EPA clarify its criteria for completeness of an 
    application. Current regulations in 40 CFR 152.50 describe the contents 
    of an application for registration, including applications for 
    antimicrobial products. EPA proposes in subpart W an expanded and more 
    detailed description of the contents of a complete application, 
    including some new elements of an application not currently required.
        2. Definition of complete application. First, EPA is proposing a 
    general definition of ``complete application'' in Sec. 152.3, a 
    definition that would apply to all applications for registration. Other 
    provisions of FIFRA also link Agency priority, review or action to 
    completeness of an application, for example, the fast-track and minor 
    use provisions of section 3(c)(3), and the expedited review provisions 
    of section 3(c)(10). The general definition is repeated in Sec. 152.442 
    to apply to antimicrobial applications.
        The definition draws a distinction between the completeness of the 
    application itself (which allows EPA to commence formal Agency review), 
    and the completeness of the information needed for EPA to approve the 
    application. It is relatively easy to define a core set of items--
    forms, labels, routine and uncomplicated data--which, if present in an 
    application, suffice to begin review. But completeness for Agency 
    decision purposes encompasses an element of ``adequacy'' that, for many 
    applications, can only be determined on a case-by-case basis, and only 
    during or after substantive review of the application. Accordingly, the 
    decision by EPA that an application is ``complete'' (and, for 
    ``antimicrobial pesticides,'' that begins a review period), represents 
    only a preliminary or interim determination of overall completeness 
    intended to allow EPA to initiate formal review.
        Completeness becomes a question of adequacy as the amount of 
    scientific data and the complexity of the risk assessment increase. 
    Typically, applications for new chemicals or new uses, and actions 
    involving food uses or increased non-dietary exposures require more 
    data. FQPA significantly expanded the scope of dietary risk assessment 
    under the FFDCA, particularly for infants and children. 
    Correspondingly, EPA will be enhancing its non-dietary assessment of 
    risks to infants and children, such as might occur with antimicrobial 
    pesticides. However, ``fast-track'' or ``me-too'' applications that 
    require little or no scientific review comprise the bulk of 
    antimicrobial applications submitted to EPA. These actions are 
    relatively straightforward as to application and approval criteria and 
    EPA expects that the completeness determinations for review purposes 
    and for approval of the application generally would be equivalent. For 
    these types of applications, EPA would be less likely to find during 
    its formal review that it requires data or information beyond that 
    provided at the time of application.
        3. Contents of an antimicrobial application. FIFRA section 3(h) 
    requires that, in its final regulation, EPA clarify criteria for 
    determination of the completeness of an application for antimicrobial 
    pesticides. EPA is proposing in Sec. 152.450 detailed requirements for 
    applications, which, if satisfied, would allow a preliminary 
    determination of completeness.
        Current requirements in Sec. 152.50 form the basis for the 
    requirements in proposed Sec. 152.450, but EPA proposes an expanded 
    level of detail. Table 3 below sets out each element of an 
    antimicrobial application as proposed today. Column 1 identifies the 
    application requirement. Column 2 gives the reference in proposed 
    Sec. 152.450 of the requirement. Column 3 gives the cross-reference to 
    Sec. 152.50, or indicates that the requirement is new. New elements are 
    discussed more fully afterwards. Column 4 provides explanatory notes, 
    indicating that a requirement is unchanged from current requirements, 
    or describing additions or changes for antimicrobial applications.

    ----------------------------------------------------------------------------------------------------------------
    
        4. New required elements of applications. Only three required 
    elements of an application are entirely new in today's proposal.
        Proposed Sec. 152.450(j) would require that applicants submit 
    documentation of the results of pre-submission conferences, either 
    those required by Sec. 152.447 or optional ones, at which regulatory-
    related decisions were discussed or agreements reached. The 
    documentation could be minutes of the meeting that EPA has reviewed, or 
    could be a letter from EPA confirming the decisions reached or 
    approving a specific test regimen or protocol.
        Proposed Sec. 152.450(k) would require the applicant to submit 
    available reviews of the application, or of individual studies, that 
    have been conducted by other regulatory agencies or organizations. If 
    an application has been submitted for regulatory review elsewhere, the 
    applicant would be required to inform EPA of that fact. Applications 
    may have been submitted concurrently to international regulatory 
    bodies, or to Federal Agencies or States. If EPA is able to use the 
    results of reviews conducted elsewhere, it will save time and resources 
    in reaching a decision on the application, which may allow earlier 
    entry into the marketplace. An applicant would not be required to 
    either await the results of ongoing reviews or to specifically obtain 
    copies of the reviews to submit with his/her application. However, if 
    reviews have been provided, the applicant would be required to submit 
    them to EPA with his/her application.
        Proposed Sec. 152.450(l) would require that applicants provide EPA 
    with documentation that they have received (or have applied for) any 
    other clearances from Federal agencies that might be necessary to 
    market or use the product. EPA currently requires such documentation 
    before issuing a registration bearing the use in question. Submission 
    with the application of evidence that the clearance has been requested 
    or obtained would help assure EPA that the applicant is fully aware of 
    its obligations under other laws. Ensuring that all regulatory 
    clearances are underway concurrently also makes the review periods for 
    EPA meaningful. EPA approval of an application within a review period 
    would have little meaning if the applicant cannot market the product or 
    users cannot use it because additional clearances are needed.
        5. Non-mandatory or clarified elements of applications. Four 
    further elements of the antimicrobial application are either clarified 
    by inclusion of explanatory language, or are voluntary information.
        Proposed Sec. 152.450(m)(2) clarifies that product packaging is not 
    to be submitted unless requested. The submission of labeling is 
    accomplished using draft typescript copies or mock-ups that are 
    suitable for microfilming and filing.
        Proposed Sec. 152.450(n) clarifies that applicants are not to 
    submit actual product samples with an application unless requested. EPA 
    typically requires samples of active ingredients or analytical 
    standards in conjunction with
    
    [[Page 50688]]
    
    setting tolerances. EPA may also request samples of antimicrobial 
    pesticides bearing public health claims for EPA evaluation of efficacy. 
    In each case, EPA will separately request such samples and instruct the 
    applicant how and where to provide them.
        Proposed Sec. 152.450(o) provides that applicants who wish to be 
    notified whether an application is preliminarily complete (and 
    therefore has been placed into review with a review period) furnish EPA 
    with a means of notifying them. This could take the form of a postcard, 
    form letter, or other means of such notification. Without an easy means 
    of notification, EPA cannot commit to written notification. Nor will 
    EPA use notification methods such as telephone or e-mail that cannot 
    properly be documented by an authorized signature as EPA-originated, 
    although advances in technology may make this feasible in the future. 
    Finally, EPA would notify the applicant only at the time the 
    application is determined to be complete; at that time the formal 
    review period would have started, and EPA's next communication with the 
    applicant would normally be a decision on the application 
    (Sec. 152.455, Action on applications.) EPA would not accept multiple 
    postcards or requests simply to advise the applicant of the status of 
    the application review during the review period.
        Proposed Sec. 152.450(q) requests, but does not require, that the 
    applicant provide authorization for EPA to share the data or EPA 
    reviews of data with other regulatory agencies. The ability to share 
    data and reviews among regulatory authorities will contribute to 
    streamlining EPA review processes for antimicrobial products, and is an 
    essential element in achieving harmonization of reviews.
        An applicant who intends to market a product in the United States 
    may be required to register the product with individual States; an 
    applicant who intends to market the product abroad (such as in Canada) 
    must meet the regulatory requirements of other countries. While the 
    depth of regulatory scrutiny of a product varies among States and 
    countries, many require the submission of equivalent amounts of data as 
    the applicant has submitted to EPA. The ability to share data submitted 
    to one regulatory authority with others can reduce the paperwork and 
    review burden of all by reducing multiple identical submissions and 
    allowing the sharing of the review load. EPA already is engaging in 
    work-sharing efforts with the State of California and with Canada.
        This effort can be complicated by confidentiality claims under 
    FIFRA section 10(b) or the disclosure restrictions of section 10(g). 
    Section 10(g) permits the Agency to disclose data in support of 
    registration only to those who affirm that they will not further 
    disclose the information to foreign or multinational pesticide 
    producers. Although a mere claim of confidentiality under FIFRA section 
    10(b) does not conclusively prevent disclosure of information, it does 
    require the Agency to follow certain procedures (which may include 
    obtaining a substantiation of the claim from the registrant) to 
    determine whether the information is entitled to confidential 
    treatment. These procedures can interfere with free and unimpeded 
    exchange of information and data among regulatory authorities.
        On November 27, 1985, EPA issued Class Determination 3-85 (50 FR 
    48833). EPA declared as non-confidential (and not subject to the 
    disclosure restrictions of FIFRA section 10(g)) reviews of data that do 
    not contain information which would disclose: (1) Manufacturing or 
    quality control processes; (2) the details of any methods for testing, 
    detecting, or measuring the quantity of any deliberately added inert 
    ingredient of a pesticide product; (3) the identity or percentage 
    quantity of any deliberately added inert ingredient of a pesticide 
    product; (4) unpublished information concerning the production, 
    distribution, sale, or inventories of a pesticide (such information 
    might appear in reviews which discuss the amount of a pesticide sold or 
    used in a given time, and thus might concern the significance of data 
    from a test or experiment); (5) any complete unpublished report 
    submitted to EPA by a registrant or applicant; or (6) excerpts or 
    restatements of any such report which reveal the full methodology and 
    complete results of the study, test, or experiment, and all explanatory 
    information necessary to understand the methodology or interpret the 
    results.
        Agency data reviews are normally drafted to avoid inclusion of 
    information that is within the six categories described in the 
    paragraph above, but EPA cannot guarantee that all reviews will meet 
    these criteria. Moreover, as discussed above, the Agency may have a 
    need to share raw data in addition to study reviews with States and 
    other countries.
        EPA believes it is in the interest of both applicants and the 
    Agency to have free and unimpeded exchange of information and data 
    among regulatory authorities. To that end, this proposal requests that 
    applicants authorize such exchange at the time of application. Sharing 
    data and reviews with other regulatory authorities would not compromise 
    the protection against disclosure provided by section 10, because such 
    sharing would not constitute a public disclosure of the information.
        To authorize data- or review-sharing, the applicant would submit a 
    statement authorizing EPA to share either any data submitted with the 
    application or EPA's reviews of such data with regulatory authorities 
    as needed. An appropriate permission statement would be similar to the 
    following:
        This letter grants permission for EPA to share all data submitted 
    with this application, EPA reviews of data submitted with this 
    application, with State, other U.S. Federal, or other national 
    regulatory authorities. This authorization does not waive any 
    restrictions on public disclosure of the data reviews.
    
    G. EPA Action on Applications
    
        1. Completeness screens. EPA currently screens all applications for 
    completeness, not just antimicrobial applications. The Office of 
    Pesticide Programs Front End Processing Unit (FEPU) receives all 
    applications, processes them administratively, and conducts a simple 
    screen to ensure that required application items are present and 
    properly submitted. An application accompanied by data is subsequently 
    screened for submission and format requirements of the data itself. 
    Data submissions must include specific items prescribed by Agency 
    regulations in 40 CFR 158.32 and 158.33, as well as meet format and 
    presentation requirements detailed in PR Notice 86-5. Neither of these 
    screens evaluates the substance of the application or the data. In 
    either the FEPU or data screen, EPA may identify deficiencies that must 
    be corrected. Depending on the nature of the deficiency, the 
    application may be placed into review anyway, and deficiencies 
    corrected during the review process. This informal screening and 
    correction process has served the Agency and applicants well over the 
    years.
        Nonetheless, because FIFRA directs EPA to develop completeness 
    criteria, and because antimicrobial pesticides are now subject to 
    review periods, which are computed only if an application is determined 
    to be complete, it is imperative that EPA not only establish more 
    formal criteria for completeness, but that EPA conduct a more rigorous 
    completeness screen before determining even preliminarily that an 
    application is complete. Section 152.455 of today's proposal describes 
    what actions EPA
    
    [[Page 50689]]
    
    may take on complete and incomplete applications.
        2. Preliminary determination of completeness. In addition to the 
    FEPU administrative screen and the data review screen, the 
    Antimicrobial Division has instituted a more in-depth screening process 
    to ensure that only applications that meet the standards of proposed 
    Sec. 152.450 enter formal Agency review. The antimicrobial screening 
    process builds on the earlier screens in two ways: by evaluating the 
    adequacy of certain application items that are typically not evaluated 
    in a simple administrative screen (e.g., are clearly required studies 
    included?), and by evaluating application requirements peculiar to 
    antimicrobial pesticides (e.g., efficacy data requirements).
        Based on this screen, EPA would make a preliminary determination 
    whether an application is complete (proposed Sec. 152.455(a) and (b)). 
    If the application is incomplete, EPA would notify the applicant, 
    describe the deficiencies and await resubmission by the applicant. If 
    complete, and a self-addressed notification has been provided in 
    accordance with proposed Sec. 152.450(o), EPA would notify the 
    applicant of the determination, compute the date under proposed 
    Sec. 152.457 when a decision may be expected (calculated from date of 
    receipt of the application), and place the application into formal 
    review. If no self-addressed notification is provided, EPA would place 
    the application into formal review, but would not notify the applicant. 
    Because some elements of completeness cannot be evaluated until the 
    application is reviewed in depth, a determination of completeness 
    sufficient to place the application into formal review must, of 
    necessity, be a preliminary one.
        EPA is likely to apply its completeness criteria very strictly, for 
    several reasons. Strict application of completeness criteria appears to 
    be consistent with the statutory direction to base enforceable 
    deadlines on completeness determinations. Further, consistent treatment 
    of applications is more likely if EPA establishes and adheres to 
    relatively ``bright line'' criteria for completeness. Finally, the 
    sheer number of applications that EPA receives means that it must 
    allocate its review resources very carefully. EPA does not believe it 
    unreasonable to use completeness determinations as a management tool 
    for those resources. While refusing entry into review for a minor 
    deficiency may appear inflexible, it is important to recognize that 
    what is flexibility for one applicant may appear to be inconsistency or 
    inequity to another. EPA believes that lack of completeness criteria 
    and inconsistent application of such criteria have been a source of 
    applicant dissatisfaction.
        3. Effect of incompleteness determination on review period. 
    Regardless of when a determination of incompleteness is made, the 
    consequence is the same: the review period would either not be computed 
    or would be halted and recomputed anew upon receipt of all items 
    completing the application. EPA would notify the applicant that the 
    application is incomplete, and specify how it can be made complete.
        4. Applicant resubmission. Proposed Sec. 152.455(b) specifies that 
    EPA will deem the review period to have begun only upon receipt of the 
    last item that completes an application. Partial information clearly 
    does not satisfy the completeness criteria, or allow the application to 
    be placed into review. EPA discourages applicants from correcting 
    application deficiencies in a piecemeal fashion; nonetheless, 
    historically this has happened (and been tolerated by the Agency) 
    because some deficiencies are easy to correct (a form not signed, an 
    unreadable draft label), while others may take longer (a missing 
    required study).
        An applicant may wish to resubmit rapidly what can be readily 
    corrected, and EPA may wish to accommodate the applicant's desire to 
    begin review of available information. As noted earlier, under the 
    current application review system, both of these can often be 
    accommodated. EPA frequently is requested and agrees to place an 
    application into review while waiting for some item that has not yet 
    been submitted, expecting that the missing item can ``catch up'' before 
    it is needed for review. Under the tight review periods provided for 
    antimicrobial application review, however, EPA cannot afford the time 
    and resources that may be lost if an applicant fails to provide the 
    needed information in a timely manner. Other applicants also suffer 
    because their applications are not reviewed as promptly as possible. 
    Accordingly, EPA would not place an application into review until all 
    deficiencies are corrected, and a preliminary determination of 
    completeness can be made.
        5. Agency review. Once EPA has issued a preliminary determination 
    of completeness, EPA will place the application into substantive Agency 
    review. EPA conducts scientific reviews in parallel as much as 
    possible, although some reviews depend upon the results of others and 
    must be conducted sequentially. Proposed Sec. 152.455(d) specifies 
    that, once in review, EPA will complete all reviews for the application 
    before issuing a decision of any sort, even a determination that the 
    application remains incomplete. EPA intends, however, to continue, to 
    the extent practicable, its longstanding practice of communicating 
    informally with applicants about interim results of reviews as they are 
    completed. Informal communications are not Agency decisions on the 
    application itself, and are entirely at the Agency's discretion.
        6. EPA decisions after review. Section 3(h)(3)(F)(i) provides that:
    
        [T]he Administrator shall notify an applicant whether an 
    application has been granted or denied not later than the final day 
    of the appropriate review period under this paragraph, unless the 
    applicant and the Administrator agree to a later date.
    
        This provision is probably the single most significant element of 
    the overall antimicrobial reform effort mandated by FIFRA. All process 
    improvements and efficiencies directed elsewhere in FIFRA section 3(h) 
    are for the purpose of shortening review periods to the goals specified 
    in FIFRA section 3(h)(2). This provision holds EPA to a decision within 
    the review periods that would be established under this proposal. EPA's 
    failure to meet those review periods is judicially reviewable.
        EPA takes seriously its mandate for antimicrobial process reforms: 
    meeting its review period goals is the most visible and tangible 
    evidence of the success of its reforms. Hence, how EPA implements this 
    provision, both in making decisions and in managing the review period 
    process, is critical.
        EPA review must culminate in one of two specified decisions--
    approval or denial--by the end of the review period. The ``review 
    period'' can be either that established in proposed Sec. 152.457, or an 
    extended review period agreed to between an applicant and EPA. The 
    statute does not provide for negotiated shorter review periods; those 
    that would be established under this proposal are minimum review 
    periods that would apply unless extended by agreement.
        The statute is silent on whether EPA may take other unspecified 
    actions prior to the expiration of the review period and what those 
    actions might be, but clearly no action other than approval or denial 
    is authorized at the end of the review period. EPA believes that it is 
    within its discretion to take interim actions prior to the expiration 
    of the review period, as long as the final decision on an application 
    is either approval or denial. Interim actions might include 
    communications with applicants on the application, preliminary 
    indications of
    
    [[Page 50690]]
    
    incompleteness or other deficiencies that might lead to denial, or 
    notice of the Agency's intent to approve the application.
        Approval is of course the desired decision from the applicant's 
    point of view. If the application is complete and relatively 
    uncomplicated, reaching a decision within the review period is mostly a 
    function of efficient management of the review process. The bulk of the 
    antimicrobial applications that EPA receives are for so-called ``me-
    too'' products and amendments (those with review periods in the range 
    of 90 days). These can be fairly characterized as uncomplicated, and 
    problems with completeness are more likely to be the reason for delays 
    in approval than the complexity of the review or decisionmaking 
    processes. Delays due to incompleteness are not included in EPA's 
    review period. A rigorous application of the completeness criteria of 
    proposed Sec. 152.450 to weed out incomplete applications should enable 
    EPA to reach a decision within the review period for applications that 
    are complete.
        For applications of greater complexity--new chemicals, major new 
    uses and other products and uses that are not substantially similar--
    the decision process is not a straightforward one-time review leading 
    to a single decision point of approval or denial. Rather it involves a 
    series of decisions, with stops and starts in the process as the 
    application progresses. Typically, such an application goes through 
    several cycles of review. Under current practice, EPA commences review 
    of an application and often determines that it is incomplete, 
    inadequate, or raises risk or efficacy concerns that must be addressed. 
    The Agency notifies the applicant and places the application into 
    pending status until the applicant responds. The ``down time'' awaiting 
    applicant response varies considerably based on the type of problem, 
    but if a new study is required, may be from 6 months to 2 years. For 
    the most complex applications, those for new chemicals and major new 
    uses, the cycle may be repeated several times. Thus, the total elapsed 
    time from beginning of review to an approval or denial decision may be 
    lengthy, but the length is generally not attributable solely to EPA 
    inaction or delay. The time may be marked by interruptions when the 
    application is awaiting applicant action and not EPA action.
        In the current review process, an interim decision is not a denial, 
    which carries the right to administrative appeals. EPA refers to such a 
    decision as a ``rejection,'' a term used to reflect the interim 
    incomplete status of the application and of EPA's review.
        The provision in FIFRA section 3(h) that EPA must reach a decision 
    within a specified review period is silent on whether or how the review 
    period should accommodate the cyclical nature of the review process, in 
    which EPA review time and applicant response time typically alternate. 
    A strict interpretation of the provision would be that the review 
    period includes applicant ``down time.''
        Congress rightly anticipated that EPA might reasonably need a 
    longer review period in certain circumstances, and the statute 
    contemplates, but does not specify, a process for reaching agreement on 
    a longer period for the formal approval or denial decision. The 
    excepting clause, ``unless the applicant and the Administrator agree to 
    a later date,'' while not perfect in that it does not reflect the 
    reality of the review process, does allow EPA and the applicant, by 
    agreement, to extend the total review period. An agreement on extension 
    could be tailored to account appropriately for applicant ``down time,'' 
    without penalizing EPA or subjecting the Agency to the threat of 
    judicial review. EPA believes that this clause provides much-needed 
    flexibility both in the types of actions that EPA may take and the 
    process by which an appropriate review period is to be agreed upon.
        Regardless of the reasons for needing an extension, EPA cannot 
    afford to engage in case-by-case negotiation for every application that 
    might approach the end of its review period without a decision. To 
    reflect more closely the actual review process, EPA needs to be able to 
    take actions before the end of the review period that have the effect 
    of extending the overall review period by stopping it for some period 
    of time. Without such flexibility, EPA may be compelled to use its 
    denial authority more frequently to meet the statutory requirement to 
    issue a decision.
        EPA does not intend to violate its regulations by failing to make 
    decisions in a timely manner. If EPA is unable for any reason to issue 
    a decision on an application within the review period, and cannot agree 
    with the applicant on an extension, EPA's failure permits the applicant 
    to seek judicial review. EPA views the judicial process as the least 
    desirable means of resolving disputes over the review period. Not only 
    is it time-consuming and costly for both parties, but a predictable 
    result of judicial review is that a court would order EPA to complete 
    review within some further period of time, an outcome which has the 
    same effect on the review schedule as if EPA and the applicant had 
    agreed to an extension.
        EPA's alternative course of action, permitted by the statute, is 
    simply to deny the application. Denial would be governed by the 
    provisions of FIFRA section 3(c)(6), which permits an administrative 
    hearing process. While EPA may thereby satisfy the requirement to issue 
    a decision and avoid the threat of judicial review, the Agency believes 
    there is little value added by the administrative hearing process, 
    which can be as protracted, costly, and uncertain as judicial review. 
    Nor does EPA believe that applicants, many of whom are small companies 
    without substantial financial or technical resources, are well served 
    by either an administrative or judicial process in this particular 
    context. Their objective is presumably to obtain an EPA decision in the 
    most timely manner and without extraordinary effort or cost on their 
    part.
        Given that individual negotiation is not feasible for any large 
    number of applications, that EPA and applicants may reasonably disagree 
    on the need for or length of extension, and that neither judicial 
    review nor denial of the application is an appealing means of resolving 
    such disputes, EPA believes it prudent to establish rules for 
    implementation of review periods that build in provisions for 
    extension. Today's proposal would do so, while not foreclosing the 
    opportunity for case-by-case extension agreements when warranted.
        Accordingly, EPA proposes in Sec. 152.455 a series of possible 
    decisions arising from substantive Agency review, incorporating 
    proposals for dealing with extensions. These are: (1) The application 
    may be approved; (2) the application remains incomplete; (3) the 
    applicant has failed to furnish sufficient information to determine 
    whether the application may be approved (two circumstances with 
    different consequences for the review period); and (4) denial for 
    cause.
        7. Approval. If EPA approves the application, it would follow its 
    customary procedures to notify the applicant by issuing a Notice of 
    Registration or letter of approval for an amendment and sending back a 
    stamped copy of the approved labeling if called for.
        8. Opportunity for rebuttal. EPA frequently issues a registration 
    that is conditioned upon the applicant's making certain corrections or 
    modifications to the registration before sale or distribution. Such 
    terms and conditions generally only require changes which are minor in 
    nature and
    
    [[Page 50691]]
    
    most often consist of labeling changes to be consistent with similar 
    products, adhere to Agency policies, or clarify label statements. In 
    EPA's experience, virtually all new registrations require some 
    modification to the label; for this reason EPA requests and approves 
    draft labeling as part of the application, and requires that the 
    applicant submit final printed labeling prior to sale or distribution 
    of the product.
        EPA's approval of the registration and permission to distribute or 
    sell the product is premised on the applicant's acceptance of EPA's 
    terms and conditions. Proposed Sec. 152.455(d)(1) would permit 
    applicants who disagree with the terms or conditions of EPA's approval 
    to submit an objection within 30 days of receipt of registration. In a 
    process analogous to the appeals process for notifications in FIFRA 
    section 3(c)(9), EPA would review the applicant's arguments and issue a 
    final decision. EPA would try to review the objection and render a 
    decision within 45 days of receipt by the Agency. It should be kept in 
    mind that EPA's limited resources must be devoted first and foremost to 
    its review period obligations for application decisions; EPA cannot 
    promise that objections to decisions already made will receive equal 
    attention.
        9. Determination that the application remains incomplete. EPA may 
    decide that, notwithstanding its preliminary determination of 
    completeness, the application remains incomplete. One reason EPA might 
    determine incompleteness is if the deficiency is the result of the 
    applicant's failure to follow well-established and clearly stated 
    guidance, procedures, or policies. Such ``incompleteness'' could be 
    identified when studies are reviewed in depth and found not to have 
    been conducted in a manner that provides EPA with adequate information 
    on which to reach a decision on the application. This type of 
    incompleteness would normally be discovered only during substantive 
    review. EPA cannot however, preclude the possibility that some 
    deficiencies could be overlooked at the earlier preliminary 
    completeness screening.
        EPA expects that it would choose to use the incompleteness 
    determination only rarely after an application is preliminarily 
    determined to be complete, electing instead to deny the application or 
    seek agreement with the applicant on an extension of the review period.
        Applications having relatively short review periods (120 
    days) are generally straightforward enough that EPA believes it would 
    catch most incomplete applications at the earlier preliminary 
    completeness screening phase. EPA believes there should be few ``me-
    too'' type applications that are determined to be incomplete after 
    entering formal review. EPA would rarely seek to extend the original 
    review period for these short-term applications since it is 
    considerably easier in Agency tracking systems to close out a review 
    period altogether than to track an extension. Tracking the review 
    period is a time-consuming operation. EPA does not believe it should 
    devote its scarce resources to tracking an original review period 
    through a series of short-term extensions. This is especially true 
    given the high volume of applications that fall into the 
    120-day review period.
        With respect to longer review period applications (120 
    days), EPA might choose to determine that an application is incomplete 
    if a deficiency is discovered early in the review process (e.g., in the 
    first 90 days of a 270-day review period).
        If, at later points in a lengthy review period (e.g., 200 days into 
    a 270-day review period), EPA judges an application to be deficient for 
    reasons attributable to incompleteness, the Agency would want to 
    examine why this is occurring. Why are incomplete applications being 
    submitted and not being identified earlier in the process? Over time, 
    as process improvements continue to be put in place and EPA and 
    applicants familiarize themselves with new procedures and requirements, 
    EPA expects that incompleteness determinations after beginning Agency 
    review would decrease. Nonetheless, EPA must reserve to itself the 
    right to determine after placing an application into formal review that 
    the application is actually incomplete.
        EPA is not obligated to begin review of or compute a review period 
    for an application that is incomplete. If EPA determines after putting 
    the application into formal review and computing a review period that 
    the application is incomplete, EPA would normally stop the review, 
    notify the applicant of its incompleteness, and recompute a new review 
    period upon receipt of submission completing the application. Proposed 
    Sec. 152.455(d)(2)(ii) specifies this typical result.
        10. Qualifying resubmission for incomplete applications. However, 
    in its discretion, EPA proposes in Sec. 152.455(d)(2)(i) to offer 
    applicants somewhat more flexibility in Agency review periods if the 
    incompleteness determination occurs after putting the application into 
    formal review and if completing the application can be accomplished on 
    an accelerated basis. For applications having short review periods 
    (120 days) and minor incompleteness deficiencies, EPA 
    believes that it need not necessarily take the full review period that 
    it would be entitled to when the complete application is resubmitted. 
    Generally, if a minor deficiency can be corrected within 30 days after 
    notice to the applicant, EPA proposes to term that resubmission a 
    ``qualifying resubmission'' and to complete review within a shorter 
    review period than would otherwise be computed. In general, 
    Sec. 152.455(d)(2)(i) proposes a subsequent review period 30 days 
    shorter than the original base review period for that type of 
    application, i.e., 60 days instead of 90 days for an identical or 
    substantially similar application, and 90 instead of 120 days for an 
    ``other new application.'' The choice to offer an abbreviated review 
    period is entirely within EPA's discretion; EPA could instead take its 
    entire review period.
        EPA proposes to limit such ``qualifying resubmissions'' to 
    applications having a review period of 120 days or less. EPA believes 
    that the incompleteness deficiencies likely to arise in such 
    applications would generally not be multiple deficiencies and are less 
    likely to involve serious data deficiencies. By contrast, EPA review of 
    an application for a new active ingredient or major new use would in 
    all probability identify multiple deficiencies, including data 
    deficiencies, not amenable to correction within 30 days.
        11. Determination that the applicant has not submitted all needed 
    information. If there are deficiencies other than incompleteness 
    deficiencies, the Agency may determine that the applicant has not 
    provided sufficient data or information to make a decision on the 
    application. EPA proposes two procedures (termed Cases 1 and 2); which 
    would apply to any particular application would depend upon the nature 
    of the deficiency. In each case, EPA would stop the review period as of 
    the date that it notifies the applicant of this decision. In neither 
    case would the review period resume until the applicant provided the 
    necessary information, and elapsed time with the applicant would not be 
    counted against EPA's original review period. The difference lies in 
    when EPA would restart the review period (the ``clock''). In Case 1, 
    EPA would restart the clock immediately upon receipt of a complete 
    resubmission correcting the deficiencies. In Case 2, EPA would restart 
    the clock only after an additional
    
    [[Page 50692]]
    
    period after receipt of a complete resubmission.
        Case 1 - Immediate restarting of the review clock. If the 
    deficiency is one that can be rapidly corrected by the applicant and 
    upon resubmission rapidly reviewed by Agency reviewers without 
    significant Agency downtime to re-review, refamiliarize, or reconstruct 
    the decision logic, EPA would restart the clock as of the date that the 
    applicant resubmitted all information or data required. EPA emphasizes 
    that EPA would restart the clock only after all deficiencies have been 
    corrected. The resubmission must also be ``complete.'' The kinds of 
    deficiencies EPA envisions in this category are short-term studies, 
    upgrading an existing study, or providing an explanation of such 
    studies.
        If EPA chose this response, the Agency would specify in its notice 
    to the applicant the deficiencies needing correction, and require that 
    they be corrected within a relatively short timeframe--based upon the 
    type of deficiency, probably less than 6 months. If the resubmission 
    time is too short, the applicant could suggest a longer time for 
    resubmission. If that resubmission time is considerably longer than EPA 
    anticipated, such that the Agency would need additional time upon 
    receipt to refresh its review, EPA would reserve the right to restart 
    the clock at some later time after resubmission (Case 2).
        Case 2 - Delayed restarting of the review clock. For deficiencies 
    that take longer to correct (e.g., new studies must be generated) or 
    where interruption of EPA review means that EPA must essentially begin 
    some portion of its review again, EPA would restart the clock after 
    both a period for applicant resubmission and an additional time for the 
    Agency to bring the review and reviewer back up to date. The longer the 
    interruption of review, the more likely it is that EPA reviewers may 
    have changed, that policies may have changed or evolved, or that the 
    original reviewer must refresh his/her knowledge of the product, the 
    application or the data. In EPA's experience, a review that is 
    interrupted for longer than 6 months has become stale.
        In this case, EPA would notify the applicant, specifying the 
    deficiencies and requiring correction by a certain date. EPA would also 
    estimate how long after resubmission the clock would start.
        12. Negotiating extended review periods for deficient applications. 
    FIFRA section 3(h)(3)(F) allows the review period to be extended by 
    agreement between EPA and applicants. As noted earlier, EPA intends 
    that this proposal set boundary rules for extending review periods, so 
    that case-by-case negotiated extensions would be used only 
    infrequently. Deficient applications for which EPA would stop the clock 
    and restart it, but where EPA cannot define the specifics of the 
    resulting extended review period are an area where negotiations would 
    be appropriate. Individual negotiation might be appropriate, for 
    example, if the deficiency entailed development of new methodology or 
    data with which EPA had no prior experience to judge its review time.
        Case 1 - Negotiating resubmission dates for simple deficiencies. 
    EPA anticipates it would provide only a limited opportunity for 
    negotiation over the appropriate resubmission time for Case 1 
    resubmissions. EPA's ability to restart the clock immediately upon 
    resubmission and thereafter to meet the review period deadline depends 
    on the fact that the deficiency can be corrected rapidly. Simply 
    restarting the clock is not feasible if protracted negotiations would 
    result in significant delay in resubmission. EPA's concern is not the 
    effect of the negotiation per se on the clock (since the clock will 
    have stopped upon notification of the deficiency), but the fact that 
    any appreciable delay in resubmission because of negotiation may mean 
    that the application review would become stale. EPA must strictly limit 
    the negotiating time for simple deficiencies, or such deficiencies 
    would, because of the passage of time, have to be treated as complex 
    deficiencies under Case 2. EPA does not intend in this proposed rule to 
    define specific types of simple deficiencies for which Case 1 could be 
    used. However, EPA solicits comment on how this procedure could be 
    implemented in a realistic manner, and what would be an appropriate 
    length of time to allow for negotiations to commence and conclude.
        Case 2 - Negotiating resubmission dates for complex deficiencies. 
    Resubmission dates would be more flexible with Case 2 complex 
    deficiencies. Because the deficiencies are complex, the resubmission is 
    expected to be on a longer schedule. Since time after notification of a 
    deficiency until resubmission is on the applicant's clock and not 
    EPA's, EPA could be flexible both in negotiating and in the 
    resubmission dates established. Unless the deficiency raised serious 
    risk concerns for a product already on the market (in which case EPA 
    likely would consider denying the application), EPA believes it could 
    generally accommodate applicant needs for resubmission.
        In addition to interruption of the review period while the 
    applicant corrects deficiencies and resubmits to the Agency, Case 2 
    negotiations would need to build in an additional period of time for 
    EPA to ``refresh'' the application review before the review period 
    clock would start. The appropriate length of this ``delay time'' is 
    less easily determined and more likely to be an issue that requires 
    negotiation between EPA and applicants. EPA is not proposing either 
    specific delay times or criteria for determining appropriate delay 
    times in this document, but is proposing to establish the ``delay 
    time'' as a regulatory decision.
        The delay time could be based on several factors. First, the delay 
    time could be a function of the actual time needed for review of the 
    submitted material (which may be one or more new studies). EPA could 
    develop some general timeframes for review of particular types of 
    studies, for example, a standard review time for a chronic toxicology 
    study or an indoor exposure study. These would serve as a starting 
    point for determining the delay time. If EPA develops such standard 
    review times for studies, it would share these with registrants and 
    others before implementing them.
        Second, the delay time could also include the time needed for EPA 
    to bring the review and reviewers back up to speed, to adjust for new 
    reviewers, and, once completed, to integrate the new material into the 
    application review and risk assessment. The longer the clock has been 
    stopped and the application put aside, the longer the time needed to 
    refresh it and the more likely that changes in personnel or policies 
    will have occurred. These times are more variable, but may depend in 
    part on the complexity of the application type. The definitions of 
    application types in proposed Sec. 152.445 roughly track the complexity 
    of an original application review and therefore how much re-review 
    might be needed to come up to speed later. EPA expects that the types 
    of deficiencies that would trigger a delay time typically would be 
    associated with new chemicals and major new uses.
        Finally, the delay time must of necessity take into account 
    variable external factors such as competing priorities and workload and 
    resource balancing. As a practical matter, although EPA may be able to 
    roughly estimate the delay time when it notifies an applicant of a 
    deficiency, the actual delay time may be dictated not by circumstances 
    at the time of notification, but by circumstances at the
    
    [[Page 50693]]
    
    time of resubmission. Depending on the nature of the deficiency, and 
    whether new studies must be generated, resubmission could be a year or 
    more away. In that time, substantial changes may have occurred within 
    the Agency that cannot reliably be predicted at the time of 
    notification.
        For example, EPA could determine that applications requiring a 
    particular set of tiered data (ecological effects, for example) 
    routinely should require 4 months delay time for a new chemical, taking 
    into account the actual review time and the re-review time. Two years 
    later, when those studies are submitted to the Agency, EPA could be in 
    a situation where its workload has doubled or key personnel are not 
    available, leading to a likely delay time of 6 months.
        EPA welcomes comment on how the ``delay time'' decision process 
    might be structured and administered for maximum efficiency and equity. 
    EPA is considering how and when negotiations on delay times are most 
    appropriately conducted. EPA solicits comment on criteria, timing, and 
    procedures that could be adopted and whether any of these should be 
    regulatory. Realistically, EPA believes that negotiation and agreement 
    on an Agency delay time can take place only at or close to the point of 
    resubmission. Further, EPA believes that negotiation procedures should 
    be informal and non-regulatory to offer the greatest flexibility, and 
    at this time is not proposing regulatory negotiation procedures. EPA 
    seeks comment on the following questions:
        Criteria. What factors are most important in determining how long 
    delay time should be? The type of application? The nature of the 
    deficiency? The elapsed or remaining review period? Other priorities?
        Timing. At what point would discussions between EPA and applicants 
    be most productive and least demanding of time and resources? Soon 
    after notification of deficiencies for planning purposes? Reasonably 
    close to the expected date of resubmission? Only after resubmission and 
    determination that the resubmission is complete?
        Procedure. Should specific negotiation procedures be developed? Are 
    discussions likely to be a frequent occurrence? Should negotiation 
    procedures be developed on a case-by-case, as-needed basis? Are 
    informal procedures sufficient or is there a need for a regulatory 
    framework?
        12. Denial for failure to submit required information (``not for 
    cause''). If EPA notifies an applicant of deficiencies, and agrees with 
    the applicant on a resubmission date for the application, and the 
    applicant fails, without good cause, to submit by that date, or fails 
    to submit a ``complete'' resubmission, EPA has the option of denying 
    the application. A denial of this type (a ``not for cause'' denial) 
    would not be for reasons of potential adverse effects (a ``for cause'' 
    denial), but because the applicant has failed to submit the information 
    the Agency required to reach a decision on the application.
        Several readings of FIFRA section 3(h)(3)(F)(i) are possible with 
    respect to a denial action the Agency may take as the endpoint of a 
    review period. EPA believes some interpretations, while plausible and 
    logical, would not likely achieve what we believe the Congress 
    intended. EPA is instead adopting an interpretation that we believe 
    both advances the goal of Congress that the Agency institute reforms to 
    improve the antimicrobial decision making process, and preserves the 
    rights of applicants under the statutory framework for denials under 
    FIFRA section 3(c)(6).
        Under one possible reading of the statute, the Agency would review 
    the application under the review periods specified in proposed 
    Sec. 152.457, and within those same review periods take all the actions 
    required under FIFRA section 3(c)(6) for denials including a 30-day 
    notice of intent to deny prior to actual denial. This interpretation 
    would effectively shorten the review periods established by section 
    3(h) by 30 days, a result that would be particularly acute in the case 
    of short review periods such as those of 120 days or less. In 
    establishing the review periods, Congress considered the amounts of 
    time the Agency requires to review various types of applications. Each 
    review period goal was intended to provide a streamlined yet presumably 
    adequate amount of time for the Agency to review these applications. 
    Congress realized that in some instances these times would not be 
    adequate and allowed for the Agency and applicant to extend the 
    applicable review period through mutual agreement. We do not believe 
    that Congress would on the one hand acknowledge EPA's possible need to 
    extend review periods, while at the same time effectively diminishing 
    each review period to accommodate the correction period for FIFRA 
    section 3(c)(6) denials.
        An equally plausible interpretation is that FIFRA section 
    3(h)(3)(F)(i) overrides the provisions of section 3(c)(6) altogether. 
    Under this interpretation, EPA would not have to issue a 30-day Notice 
    of Intent, or provide opportunity for a hearing. However, there is no 
    indication of Congressional intent to diminish the opportunity for an 
    applicant to remedy deficiencies and/or request a hearing for denials 
    of applications.
        EPA believes a third interpretation is reasonable and more 
    appropriate. EPA would regard the Notice of Intent to Deny (NOID) 
    required by FIFRA section 3(c)(6) as the practical equivalent of a 
    denial under FIFRA section 3(h). At the point a decision is reached 
    under Sec. 152.457 (including any extended review periods), EPA would 
    commence the FIFRA section 3(c)(6) denial process by issuing a NOID. 
    Under this interpretation, the Agency would have the full review period 
    contemplated by Congress, and applicants would be afforded the 
    protections intended for FIFRA section 3(c)(6) denials. Accordingly, 
    proposed Sec. 152.455 would provide that the 30-day NOID itself 
    constitutes the denial decision required by section 3(h)(3).
        Denial under FIFRA section 3(h)(3) would be the same as denial 
    under FIFRA section 3(c)(6). Legally, EPA would find that the applicant 
    has failed to meet the registration standard of section 3(c)(5), in 
    that ``its labeling and other material required to be submitted'' do 
    not ``comply with the requirements of the Act.'' EPA's determination to 
    deny an application would set in motion a process that entails the 
    NOID, opportunity for the applicant to correct the application 
    deficiencies within 30 days, final denial if deficiencies are not 
    corrected, and the opportunity for an administrative hearing process. 
    Denial procedures are found in Sec. 152.118.
        EPA would be unlikely to allow additional time for correction 
    beyond the 30 days provided by the NOID, for several reasons. First, 
    EPA has already notified the applicant previously and agreed upon an 
    appropriate time for submitting additional data (of a long-term 
    nature). Additional discussion at this point would not seem justified 
    in light of the previous negotiations. Second, as noted earlier, EPA's 
    tracking system will be strained if EPA must repeatedly recompute the 
    elapsed review period due to extensions, new resubmission dates, or 
    additional EPA review times. EPA and applicants will not be well served 
    if tracking system needs overwhelm the review process. At some point, 
    EPA must reach closure on an application. Finally, there is the issue 
    of equity among applicants. Negotiating time for any application is 
    decreased review time for all applications, and should be allocated 
    evenly across applications rather than consumed on a single undeserving 
    application.
    
    [[Page 50694]]
    
        As an alternative, EPA could determine that the failure to resubmit 
    properly and on time renders the application incomplete. In either 
    case, the effect on the review clock is the same: it would start over 
    whenever the applicant submitted the complete data or properly 
    completed the application.
        14. Denial for failure to meet the registration standard (``for 
    cause''). Finally, as already provided by the statute, EPA can 
    determine that an application should be denied because the pesticide or 
    its uses pose unreasonable adverse effects on man or the environment (a 
    ``for cause'' denial). Legally, EPA would determine that it fails to 
    meet the registration standard of FIFRA section 3(c)(5)(C) or (D).
        As in the case of a not-for-cause denial, EPA would follow the 
    denial procedures of FIFRA section 3(c)(6) and Sec. 152.118. Also as 
    noted above, EPA would treat the NOID as the decision required by FIFRA 
    section 3(h). EPA expects a denial for cause to be a rare occurrence.
    
    H. Review Periods
    
        1. Statutory provisions. Although FIFRA section 3(h) is premised 
    upon the establishment of decision-making deadlines, it does not 
    prescribe a specific set of review periods that EPA must adopt by 
    regulation, However, section 3(h) does contain two sets of review 
    periods that express Congressional intent in this area. EPA has given 
    careful consideration to each, discussed in this unit, and is today 
    proposing one.
        First, section 3(h)(2) establishes review time period reduction 
    ``goals,'' ranging from 90 days to 540 days, whose achievement is tied 
    to the implementation of the process reforms required by section 
    3(h)(1). Under section 3(h)(1), the explicit purpose of the process 
    reforms is to achieve the ``goal'' review periods. The statute stops 
    short of requiring that EPA adopt by regulation a set of statutorily-
    mandated review periods. The statute appears to anticipate that EPA's 
    management reforms might take some time to fully implement to achieve 
    the goal review periods: section 3(h)(4) requires EPA to submit an 
    annual report to appropriate Congressional committees documenting its 
    progress toward the goals. Thus, while EPA is to work toward the goal 
    review periods, Congress did not require EPA to adopt the ``goal'' 
    review periods in its regulation. EPA may include other review periods 
    in the regulation so long as it complies with other requirements 
    triggered if the goals are not met.
        Congress did, however, intend that EPA should take the goal review 
    periods seriously, and therefore put in place two provisions that are 
    triggered if EPA does not meet the goal review periods. The annual 
    report mentioned above is to be submitted ``beginning on the date of 
    enactment of this subsection and ending on the date that the goals 
    under paragraph (2) [the goal review periods] are achieved.'' Thus, as 
    long as EPA is not meeting any statutory ``goal'' review periods, for 
    whatever reason, it must continue to report to Congress on its 
    progress. The first such annual report was issued in October 1997 (EPA 
    739-R-97-001).
        Moreover, if EPA issues a final regulation that fails to meet any 
    of the goals, it also must comply with the requirements of section 
    3(h)(3)(B)(ii) by identifying in the final rule any unmet goal, 
    explaining why the goal was not met, describing the elements of the 
    regulations included instead, and identifying future steps to attain 
    the goal. Again, the statute does not require that EPA propose a 
    statutorily-identified set of regulatory review periods, though a 
    timeframe is required to be included in the regulation.
        The second statement of Congressional intent, in section 
    3(h)(3)(D), establishes ``default'' review periods, ranging from 90 
    days to 2 years, that automatically took effect on April 25, 1998, 
    since EPA's final regulation was not effective by that date. The 
    ``default'' review periods are equal to or longer than the ``goal'' 
    review periods, depending upon the type of application. After 
    promulgation of this regulation, the default review periods will be 
    replaced by time periods specified in the final rule. In the 
    legislative history of the antimicrobial provisions, it is stated that 
    ``maximum time periods for review are specified in Subtitle B for 
    various activities.'' [Subtitle B contains the amendments in FIFRA 
    section 3(h)]. Since the default review periods are in fact the 
    ``maximum review periods specified'' in section 3(h), this language 
    could be read to suggest that Congress intended the default review 
    periods to be adopted by the Agency in its regulation. However, EPA 
    views the ``default'' review periods as a ``hammer'' provision to 
    encourage timely promulgation of its antimicrobial final rule 
    containing EPA-specified review periods, rather than a statement of 
    Congressional intent as to what review periods should be adopted.
        2. EPA proposal. EPA is today proposing the ``goal'' review 
    periods. Since these are the benchmark of the management and process 
    reforms contemplated by Congress, EPA believes they are more 
    appropriate than any other review periods, which would of necessity 
    serve only in an interim capacity until the ``goal'' review periods 
    could be met. As an alternative, EPA could consider and would like 
    comment on the options of: adopting no review periods by regulation and 
    relying on administrative review periods; adopting the ``default'' 
    review periods; or adopting some other review periods. Commenters who 
    support this last option should be specific as to the review periods 
    sought and why. If other than the goal review periods are ultimately 
    adopted, EPA would strive to meet the goal review periods, as it has 
    since FQPA was enacted.
        Section 152.457 of today's proposal sets out EPA's proposed review 
    periods. The three tables in that section address, respectively, 
    approvals of new registrations, amended registrations, and ``qualifying 
    resubmissions.'' As noted in Unit VIII.D., EPA proposes to review an 
    application for a major new use within 270 days, regardless of whether 
    that application is a new registration or an amendment to an existing 
    registration. Accordingly the tables in Sec. 152.457(c) and (d) both 
    include ``major new use.'' Proposed Sec. 152.457 also sets out the 
    limitations of applicability of review periods.
        3. Food use antimicrobial products. As defined by FIFRA section 
    2(mm), antimicrobial pesticides do not include products whose intended 
    use would require a clearance under the FFDCA. As noted in Unit VI.B., 
    EPA intends to apply this exception so as to exclude only applications 
    that would require a new or revised clearance. Applications subject to 
    an existing clearance that does not need revision would be 
    antimicrobial pesticides.
        4. Wood preservatives. The statutory definition also excludes 
    aquatic herbicides and some wood preservatives and antifoulants from 
    definition as ``antimicrobial pesticides.'' Applications for 
    registration of such products are not covered by subpart W and are not 
    eligible for the review periods of Sec. 152.457.
        However, under FIFRA section 3(h)(3)(E), applications for wood 
    preservatives (and only wood preservatives) are eligible for the 
    statutorily-required review periods that would be established by this 
    proposal if they meet certain conditions:
         First, the application must be for a wood preservative 
    that bears an antimicrobial claim as defined in FIFRA section 2(mm), 
    even if other non-antimicrobial wood preservative claims (such as 
    fungus or insect protection) are made.
         Second, the data requirements to support the wood 
    preservative product
    
    [[Page 50695]]
    
    that is not an ``antimicrobial pesticide'' must be the same as the data 
    requirements that support a wood preservative that is an 
    ``antimicrobial pesticide.'' In general, the data requirements in part 
    158 are the same for all wood preservatives, regardless of the type of 
    wood preservative claim made. Thus, all wood preservative products 
    fulfill this criterion.
         Finally, the applicability of the statutorily-required 
    review period to a wood preservative application is to be ``consistent 
    with the degree of risk posed by the use of the wood preservative.'' 
    EPA interprets this clause to permit the Agency, in its discretion and 
    on a case-by-case basis, to determine that an individual wood 
    preservative application is not subject to the statutorily-required 
    review period based on risk concerns.
        For example, EPA might exercise this discretion for an application 
    that initially would have a review period of 180 days. During the 
    review, however, EPA discovers that the wood preservative use poses 
    significantly greater risks than a typical ``substantive new use'' 
    application. This might occur if the treated wood were intended for use 
    in a manner that greatly increased or changed the exposure potential to 
    humans or other species. To evaluate the increased risk, EPA might need 
    more than 180 days, even if substantial new data were not required. In 
    this situation, EPA would notify the wood preservative applicant that 
    the application was no longer entitled to a statutorily-required review 
    period, and specify the risk reasons therefor.
        EPA would make every effort in its notification to estimate when 
    the application review would be completed, although the application 
    would no longer qualify for review period coverage. EPA regards its 
    notification to the wood preservative applicant of a risk differential 
    basis for review as relieving EPA of its obligation to complete review 
    within any statutorily-required review period.
        5. Fast-track applications. Fast-track applications are described 
    in FIFRA section 3(c)(3). Fast-track applications are not limited to 
    antimicrobial products, and EPA is required to reach a decision on the 
    application within 90 days. Currently, there are no regulations for 
    fast-track applications, and none are needed because the statute sets 
    out clear deadlines for completion of review. The review period for an 
    antimicrobial pesticide specifically does not affect or substitute for 
    the timeframe for a fast-track review of an antimicrobial pesticide. 
    Generally, antimicrobial applications for identical or substantially 
    similar new products or minor amendments are equivalent to fast-track 
    applications, and would be decided under either provision within 90 
    days.
        As a legal matter, however, an application must be reviewed either 
    as a fast-track application or an antimicrobial application--a single 
    application cannot be both. EPA interprets FIFRA section 
    3(h)(3)(F)(iii) to place an application that could qualify as either a 
    ``fast-track'' or ``antimicrobial pesticide'' application squarely 
    under the antimicrobial provisions and review periods. While there are 
    minor procedural differences between 90-day fast-track decisions and 
    90-day antimicrobial review period decisions, the significant 
    difference between the two is that a fast-track action is not 
    judicially reviewable if EPA fails to render its decision within 90 
    days while an antimicrobial action is judicially reviewable.
    
    IX. Duration of Registration for Products Bearing Public Health 
    Claims
    
        EPA proposes in Sec. 152.458 to establish terms for a time-limited 
    registration of products bearing a public health claim. The term of a 
    registration would be limited to no more than 5 years. The registration 
    could be continued only if the registrant conducts product analysis and 
    efficacy testing that confirms that the product continues to meet the 
    applicable registration standards of FIFRA section 3(c)(5). EPA 
    believes that it is authorized to establish this provision under the 
    authority of sections 3(h) and 25(a).
    
    A. Statutory Requirements
    
        FIFRA section 3(h)(3)(A)(ii)(IV) mandates two things: (1) that EPA 
    ``. . . ensure that the registration process is sufficient to maintain 
    antimicrobial pesticide efficacy''; and (2) that ``antimicrobial 
    pesticide products continue to meet product performance standards and 
    effectiveness levels for each type of label claim made.'' Section 3(h) 
    focuses on the registration process as a means of ensuring continued 
    product performance. More important, however, is the strong 
    Congressional directive to ensure continued product performance and 
    effectiveness after registration. Thus, under section 3(h), EPA must 
    address post-registration efficacy in the antimicrobial regulation 
    proposed today.
        EPA is also authorized under FIFRA section 25(a) to issue 
    regulations to carry out the provisions of the Act. Such regulations 
    must specifically ``take into account the difference in concept and 
    usage between various classes of pesticides, including public health 
    pesticides and differences in environmental risk and the appropriate 
    data for evaluating such risk between agricultural, nonagricultural, 
    and public health pesticides.'' ``Public health pesticide'' is defined 
    in FIFRA section 2(nn) to include, among other things, pesticide 
    products intended for use against ``viruses, bacteria, or other 
    microorganisms . . . that pose a threat to public health.'' The 
    references in FIFRA section 25(a) singling out public health pesticides 
    were added by FQPA, and EPA regards their addition as expressing 
    Congressional intent that public health pesticides as a class should be 
    distinguished from other pesticides when considering regulatory 
    requirements, including this proposal.
        Taken together, EPA believes that the clear Congressional intent 
    expressed in section 3(h) to ensure post-registration product 
    performance and effectiveness, coupled with the authority conferred by 
    section 25(a), authorize EPA to establish by regulation binding 
    requirements on registrants of antimicrobial public health products to 
    ensure continued product efficacy. The requirements relate to initial 
    registration and also extend into post-registration activities.
    
    B. Alternatives Considered
    
        As noted in Unit IV.E., EPA has relied on enforcement mechanisms to 
    ensure post-registration efficacy; EPA will continue to use these as 
    appropriate. But, because failure of an antimicrobial public health 
    product to work as intended cannot normally be detected by the user and 
    can have serious health and safety consequences or other unreasonable 
    adverse effects, it is critical that EPA use all available regulatory 
    and enforcement mechanisms to ensure public health protection.
        One means of ensuring continued efficacy after registration would 
    be through the statutorily required re-review of products. FIFRA 
    contains two provisions that require EPA to reassess each registration 
    according to the latest scientific standards, which for public health 
    products would include an efficacy review. FIFRA section 4 requires a 
    one-time reregistration of each product first registered before 
    November 1984. This process is underway, but to date few antimicrobial 
    products have been reviewed under section 4, and products registered 
    since 1984 are not subject to reregistration. Additionally, FIFRA 
    section 3(g) requires EPA to periodically review each registration, 
    with a goal of re-reviewing each product every 15 years.
    
    [[Page 50696]]
    
        Although these provisions will be useful in ensuring that pesticide 
    products continue to meet the registration standard, based upon up-to-
    date scientific standards, EPA believes that more product oversight is 
    needed to meet the mandate of FIFRA section 3(h) to ensure continued 
    efficacy of antimicrobial public health products. Neither a one-time 
    re-review nor a periodic review only every 15 years offers adequate 
    assurance of continued efficacy of products so critical to public 
    health protection. EPA believes that by requiring the re-testing of 
    products at more frequent intervals than every 15 years, complemented 
    by EPA, State and other testing programs, it can be better assured of 
    continued product efficacy, without incurring to itself or imposing 
    upon registrants significant additional costs.
        Alternatively, EPA could establish, or require registrants to 
    establish, an ongoing quality control and efficacy monitoring program 
    to evaluate product composition and efficacy on a frequent basis. EPA 
    conducted a one-time testing of sterilant products, and is conducting 
    similar testing of hospital disinfectant products. EPA believes that 
    many antimicrobial registrants, fully aware of the need for continuing 
    quality control and efficacy, already test their products on a routine 
    basis, although EPA currently has no data on the number of producers 
    who do so, the type of testing conducted, or how frequently it is done. 
    A formalized testing program, whether by EPA or registrants, would 
    obviously be one way to meet the mandate of FIFRA section 3(h), and, if 
    conducted at frequent intervals, would offer the greatest assurance of 
    continued product performance and public health protection. EPA itself 
    does not have the resources to establish and sustain such a program, 
    and so EPA proposes that registrants bear the cost of such testing. Two 
    approaches have been considered, and one is being proposed today.
        One such method would be to require that a public health applicant 
    develop and submit for Agency approval as part of his/her application 
    for registration or reregistration a plan for continuous quality 
    control and efficacy testing. Such a requirement would meet the mandate 
    of using the registration process to ensure efficacy, as well as 
    ensuring continued post-registration needs. Upon approval of the 
    registration or reregistration, the plan would become a term of the 
    registration and would be binding on the registrant. The benefit of 
    this approach is that public health applicants would be afforded the 
    greatest flexibility to design a program that they believe satisfies 
    the needs of the Agency. However, approval of a plan would require 
    greater review resources for the Agency, and potentially lead to delays 
    in approval beyond the established review periods required by 
    Sec. 152.458. Comments are requested as to the value, feasibility, and 
    potential costs of such a requirement, as well as criteria for 
    evaluating plans. EPA is not proposing this option today, but could 
    adopt it in the final rule. If EPA does so, it would include the 
    requirement for a public health quality control and efficacy monitoring 
    plan in Sec. 152.450.
        EPA seeks information on current registrant- or producer-imposed 
    quality control measures, whether producers are currently routinely 
    conducting efficacy testing on a batch basis or at frequent intervals, 
    and what type of testing is conducted. Finally, comments are solicited 
    on any additional ways of ensuring continued efficacy of public health 
    products; suggestions would be considered for future implementation, 
    either administratively or by regulation.
    
    C. Sunset Provision
    
        1. Maximum 5-year registration term. EPA proposes to implement a 
    periodic and regular testing program by limiting the duration of a new 
    antimicrobial public health registration to no more than 5 years from 
    the date of initial registration of the new product. EPA would 
    incorporate the 5-year expiration into the approval of the application 
    as a term of registration. Every 5 years, in order to avoid expiration, 
    the registrant would have to conduct the testing described in 
    Sec. 152.458(b)(3) and certify that the product has passed the tests.
        The Agency is also proposing to require testing every 5 years as a 
    prerequisite for maintaining the registrations of existing products, 
    i.e., products registered as of the effective date of the rule. For 
    existing products, the 5-year period would begin on the earliest of: 
    (1) The date of first amendment after the effective date; (2) the date 
    of reregistration under FIFRA section 4; or (3) a date certain 
    approximately 6 months after the effective date of the rule. EPA would 
    in the final rule specify the date certain, which, based on current 
    projected schedules, would be no earlier than August 1, 2000. This last 
    date would ensure that all products registered at the time the rule 
    becomes effective would be brought into the retesting scheme. EPA 
    expects that this default date would govern for most existing products, 
    since the number of amendments and reregistrations that could be 
    expected in the 6-month period is unlikely to approach the number of 
    public health registrations (currently estimated at approximately 3,000 
    products).
        In the case of an amendment or reregistration, EPA approval letters 
    would include the 5-year requirement. Because there would otherwise be 
    no Agency notification for products that become subject on the specific 
    default date, EPA would notify all such registrants of the effective 
    date.
        EPA is proposing this phased introduction of the testing 
    requirement for existing products because it believes that phased 
    testing will create less strain upon laboratory demand for testing and 
    upon Agency resources. It would, however, complicate the tracking of 
    expiration dates.
        As an alternative, EPA could begin the 5-year retesting requirement 
    on a single date for all existing products. While this would ensure 
    equity for existing products and simplify calculation of expiration 
    dates for both registrants and the Agency, it could lead to high demand 
    for laboratory testing on a compressed schedule every 5 years. Even 
    with a single date for existing products, new products would become 
    subject to the retesting requirement on a phased basis as they are 
    registered; thus, there would always be some phasing of the retesting 
    requirement. Over time, as new products are registered and existing 
    ones taken off the market, the phased testing scheme would become the 
    norm rather than the exception. If EPA were to adopt a single date, it 
    would specify the date in the final rule.
        In any case, the scope of EPA's determination of continued 
    registrability at the 5-year intervals would be limited to the 
    composition and efficacy standards in FIFRA section 3(c)(5)(A) and (C), 
    i.e., that the product's composition ``is such as to warrant the 
    proposed claims for it,'' and that ``it will perform its intended 
    function [without unreasonable adverse effects on the environment].'' 
    EPA's evaluation would be limited to products bearing public health 
    claims and its determination to whether the product would perform its 
    intended function at the antimicrobial levels claimed. EPA would not 
    expect to reevaluate the potential adverse effects of the product every 
    5 years, but generally would reserve such evaluation for a 15-year 
    review cycle. Thus, in any given 15-year period, EPA typically would 
    review each product once under the 15-year statutory review provision 
    and 3 times for efficacy purposes. Notwithstanding these scheduled 
    review intervals, EPA may conduct a review of a product for any purpose 
    (including, but not limited to, efficacy
    
    [[Page 50697]]
    
    concerns) at any time and take regulatory or enforcement action based 
    upon its findings.
        EPA believes that a quality control check and efficacy evaluation 
    at least every 5 years is needed to ensure continued efficacy. However, 
    the Agency solicits comment as to whether a different registration term 
    should be implemented, either more or less than 5 years.
        2. Data requirements. To meet the product composition standard, 
    proposed Sec. 152.458 would require a chemical analysis demonstrating 
    that the product conforms to the composition approved by EPA on the 
    most recent Statement of Formula, conducted according to the analytical 
    method that the registrant is required to provide the Agency under 40 
    CFR 158.180.
        To meet the product efficacy standard, proposed Sec. 152.458 would 
    require that the registrant conduct the battery of efficacy tests that 
    would be required to support the product if it were submitted for new 
    registration at that time, conducted in accordance with the most 
    current Agency testing guidelines. Testing guidelines for antimicrobial 
    products are evolving, and testing would have to reflect the methods 
    and standards recognized by EPA at the time of the required testing.
        To ensure that the testing reflected the product as distributed and 
    sold at the 5-year mark, the testing would have to be conducted during 
    the final year of the 5-year registration period (or other renewal 
    period if 5 years is not selected). Although EPA believes it is in the 
    interest of registrants to conduct such analysis and testing more 
    frequently as a matter of good business practice, only testing 
    conducted within the last year could be used to support renewal of 
    product registration.
        3. Certification procedure for compliance. EPA believes that it can 
    accomplish this limited renewal program and monitor compliance without 
    routinely reviewing the actual test results. In accordance with the 
    mandate of FIFRA section 3(h)(3)(B)(iii) to ``consider the 
    establishment of a certification process for regulatory actions 
    involving risks that can be responsibly managed . . . in the most cost-
    efficient manner,'' EPA proposes to use a certification process as the 
    most cost-effective means of administering the program. Each registrant 
    would certify in writing to the Agency that the testing had been 
    conducted as required in accordance with EPA Good Laboratory Practice 
    Standards, and that the results demonstrate that the product meets the 
    composition and efficacy standards specified. The certification must be 
    signed by an authorized representative of the registrant. As a 
    condition of registration, EPA would require that test results be made 
    available immediately to EPA upon request; EPA expects that it would 
    selectively review the data for some products.
        The required certification would have to be submitted to the Office 
    of Pesticide Programs no later than 90 days prior to each successive 
    expiration date of the registration, to allow sufficient time for EPA 
    to process it and notify the registrant of its determination. If at any 
    time after the renewal, the Agency determined that the certification 
    was false or the data upon which it was based do not support the 
    certification for any reason, the registration would be subject to 
    regulatory or enforcement action or both.
        4. Failure to submit. EPA would not notify registrants of the 
    upcoming expiration of their product registrations. Registrants would 
    be responsible for monitoring the status of their registrations, 
    conducting the testing and submitting the required certification in a 
    timely manner. Failure to submit would result in the expiration of the 
    registration automatically and without hearing rights. If the 
    registration expired, the registrant would have to submit a new 
    application for registration to once again market the product.
        If EPA has no other information or data to suggest that the product 
    is no longer efficacious, EPA would permit the registrant 90 days to 
    distribute and sell his/her existing stocks of product (product in 
    existence on or before the date of registration expiration). Product 
    already distributed by the registrant and in channels of trade could be 
    distributed and sold for 1 year after expiration.
        5. Products that fail efficacy testing. If a product fails efficacy 
    testing at its 5-year renewal, the registrant would be unable to 
    certify as required by Sec. 152.458, and the product registration would 
    expire at its 5-year anniversary.
        Moreover, there is a continuing obligation under FIFRA section 
    6(a)(2) to report information concerning adverse effects to the Agency. 
    In certain cases this obligation extends beyond the life of the 
    registration (for example, to an expired registration). If the 
    registrant conducts efficacy testing at any time, and the product fails 
    to meet the performance standard of part 156, subpart W, for each 
    public health claim, the registrant is required to report such failure 
    to EPA in accordance with the procedures and timeframes in 40 CFR part 
    159. Section 159.188 specifically details the information required to 
    be submitted concerning antimicrobial public health products. The 
    requirement to submit under FIFRA section 6(a)(2) and the regulations 
    in 40 CFR part 159 is a separate requirement from that under this 
    proposal.
    
    X. General Conditions of Registration
    
        EPA proposes in Sec. 152.459 to establish conditions of 
    registration for antimicrobial pesticides. Under FIFRA section 3(c)(7), 
    EPA is authorized to register pesticide products conditionally. Current 
    regulations in Sec. 152.115 implement EPA's authority, and specify 
    general conditions applicable to registrations. Section 152.115(c) 
    permits EPA to establish, on a case-by-case basis, other conditions 
    applicable to registration under FIFRA section 3(c)(7).
        For antimicrobial pesticides, EPA proposes in Sec. 152.459(a) to 
    cross-reference the conditions of Sec. 152.115. These conditions relate 
    primarily to submission of missing data subsequent to registration.
        Further, EPA proposes to establish as a condition of registration a 
    requirement that registrants of non-public health products submit 
    efficacy data upon request by the Agency. Registrants are currently 
    required to maintain efficacy data for non-public health products, but 
    EPA does not routinely review them as part of the application. Upon 
    request, registrants are required to submit the data. When this request 
    is made prior to approval of a new application, EPA can refuse to 
    register the product if the registrant does not comply. EPA proposes in 
    Sec. 152.459(b) to establish as a condition of registration that 
    registrants must submit upon request any efficacy data for a non-public 
    health product that were not required to be submitted with the 
    application. By establishing submission as a condition of registration, 
    EPA makes explicit the authority and action it will take (expedited 
    cancellation under FIFRA section 6(e)) if registrants fail to provide 
    these data after registration.
    
    XI. EPA/FDA Jurisdiction Over Antimicrobial Products Used in or on 
    Food
    
    A. Background
    
        Since EPA was created in 1970, EPA and FDA have shared authority 
    under FFDCA over pesticide residues in food. Prior to FQPA, the 
    division of jurisdiction between EPA and FDA was governed by a number 
    of somewhat complicated provisions of FFDCA. FQPA modified the FFDCA to 
    create much clearer lines of jurisdiction. In the
    
    [[Page 50698]]
    
    process, FQPA transferred to EPA regulatory responsibility for a number 
    of antimicrobial substances which for many years had been under FDA 
    jurisdiction.
        In the 2 years after FQPA enactment, EPA and FDA held extensive 
    discussions on their respective legal authorities pre- and post-FQPA. 
    The two agencies issued a joint Federal Register notice entitled 
    ``Legal and Policy Interpretation of the Jurisdiction under the Federal 
    Food, Drug, and Cosmetic Act of the Food and Drug Administration and 
    the Environmental Protection Agency over the use of Antimicrobial 
    Substances with the Potential to Become Components of Food'' 
    [hereinafter ``Policy Interpretation''] issued in the Federal Register 
    on October 9, 1998 (63 FR 54532) (FRL-5773-8). In that notice EPA and 
    FDA discussed a proposed allocation of jurisdiction over antimicrobial 
    substances which would transfer back to FDA regulatory authority over 
    many of the substances that had been transferred to EPA in 1996 by 
    FQPA.
        EPA would have effected the transfer in a subsequent regulation by 
    revising its declaration of a FIFRA ``pest'' in Sec. 152.5 to exclude 
    certain microorganisms occurring in food processing facilities, 
    packaging and food contact articles. Readers are referred to the Policy 
    Interpretation for a full discussion of the proposed approach.
    
    B. FDA Regains FFDCA Jurisdiction
    
        On October 30, 1998, however, Congress passed the ``Antimicrobial 
    Regulation Technical Corrections Act of 1998'' (ARTCA), Public L. 105-
    324, which amended FFDCA section 201(q)(1) and 408(j) in a manner that 
    essentially accomplished the two Agencies' planned regulatory approach, 
    and obviated the need for EPA to issue regulations. ARTCA supersedes 
    the Policy Interpretation with respect to FFDCA regulatory authority 
    over antimicrobial residues in food except for residues of ethylene and 
    propylene oxides, which were retained as ``pesticides.'' ARTCA, 
    however, does not address the interpretation of the FIFRA term 
    ``processed food'' that was included in the Policy Interpretation.
    
    C. EPA Retains FIFRA Jurisdiction
    
        Under the Policy Interpretation, EPA intended to propose to yield 
    both FFDCA and FIFRA authority over those antimicrobial substances 
    addressed in the Policy Interpretation. EPA and FDA viewed the 
    regulatory approach of redefining FIFRA ``pests'' to be the best means 
    of accomplishing the transfer agreed upon between the Agencies. No 
    authority under FFDCA would have achieved this objective before passage 
    of ARTCA.
        Unlike the proposed change discussed in the Policy Interpretation, 
    however, the statutory change put in place by ARTCA affects only FFDCA 
    authority over antimicrobial residues in food. ARTCA does not affect 
    the status of any substance as a ``pesticide'' within the meaning of 
    FIFRA. The legislative history of ARTCA makes this point clear:
    
        This amendment would affect the regulation of antimicrobial 
    pesticides only under the FFDCA. EPA would continue to regulate 
    antimicrobial pesticides under FIFRA, and EPA's authorities under 
    that statute would not be changed.
    
        In light of ARTCA, which provides specific Congressional direction, 
    EPA is not proposing to exclude or exempt these products from FIFRA 
    requirements, as discussed in the Policy Interpretation.
        Because the legislation is complex, EPA has developed an overview 
    table of current FFDCA authority post-ARTCA. Table 4 below is an 
    overview of antimicrobial substances whose use may result in residues 
    in food. Column 1 lists the category of antimicrobial substances. 
    Column 2 further subdivides the major categories. Column 3 gives the 
    current jurisdiction under FFDCA over antimicrobial substances after 
    ARTCA. Note that, even where FFDCA authority is vested in FDA, EPA 
    retains FIFRA authority for antimicrobial products other than those 
    used on processed food. Such products will continue to require 
    registration.

    aThe term ``food'' is defined according to FFDCA section 201(f).
    bEPA has used this term for convenience in this overview table. FFDCA
      section 2(q)(1)(B) describes the scope of activities to include
      ``locations where food is prepared, packed, or held for commercial
      purposes.''
    cEPA has used this term for convenience in this overview table. FFDCA
      section 2(q)(1)(B) describes the scope of these treatments to include:
      (1) treatments in facilities where the treatment does not change the
      raw agricultural status of the food; and (2) treatments applied during
      transportation between the field and the treatment facility.
    
    XII. Efficacy Performance and Labeling Standards for Antimicrobial 
    Products
    
        EPA proposes to create a new Subpart W (Secs. 156.440 through 
    156.458) in part 156, entitled Public Health Claims for Antimicrobial 
    Pesticides. Subpart W would establish labeling requirements for 
    antimicrobial pesticides that make public health claims based upon the 
    level and type of efficacy demonstrated by testing. The efficacy 
    performance standards upon which the proposed requirements are based 
    are derived from the testing requirements of 40 CFR part 158, and the 
    test methods and standards provided in Subdivision G of the Pesticide 
    Assessment Guidelines. Today's proposal would also codify certain 
    labeling requirements that are currently applied to antimicrobial 
    pesticides individually at the time of registration, but are contained 
    only in Guidelines (Subdivision H of the Pesticide Guidelines). Neither 
    the performance standards nor the labeling requirements are a departure 
    from current and longstanding policies.
    
    A. Need for Rule
    
        EPA bears a special responsibility to ensure that antimicrobial 
    efficacy for public health products be substantiated and maintained 
    over the life of the product because of the potentially serious 
    consequences of lack of efficacy, and the fact that users cannot 
    independently ascertain product efficacy. For that reason, EPA not only 
    must review antimicrobial efficacy data to ensure that products indeed 
    perform at the claimed level of antimicrobial activity, but also must 
    assure that product labeling accurately expresses the type and level of 
    activity to be expected. Effective control of public health pests is 
    not only a function of the availability of products that work as 
    intended, but also of users' ability to select an appropriate product 
    for their needs, and to use it properly. The product labeling is 
    critical in conveying this information. By issuing performance 
    standards and associated labeling standards as rules rather than the 
    current Guidelines, EPA expects to ensure consistency in labeling, 
    promote a common understanding among registrants and the user community 
    of performance expectations and limitations, and thereby maintain the 
    benefits of these products in protecting public health.
    
    B. 1984 Proposal
    
        EPA originally proposed these performance and labeling standards in 
    substantially similar form in 1984 as part of a larger general 
    pesticide labeling proposal (September 26, 1984, 49 FR 37959), but did 
    not finalize them. Because of the intervening time, EPA is reproposing 
    those efficacy performance and labeling standards today. In response to 
    the 1984 proposal, EPA received eight comments pertaining to the 
    efficacy performance and labeling standards. The commenters included 
    two trade associations (the Chemical Specialties Manufacturers' 
    Association and the International Sanitary Supply Association), and six 
    individual producers of antimicrobial pesticides. A copy of these 
    comments or a summary is available in the public docket. EPA has not 
    reviewed these comments in detail for this new proposal, and invites 
    commenters to reiterate any comments they believe are relevant to this 
    proposal.
    
    C. Current Proposal
    
        Every pesticide product must be properly labeled, in accordance 
    with general labeling requirements of part 156, including, among other 
    things, use directions that describe the site of application, the 
    target pests associated with each site, the dosage rate, the method of 
    application, the frequency and timing of application and any particular 
    limitations on use. Antimicrobial products covered by subpart W must 
    comply with part 156 labeling requirements. In addition, for public 
    health antimicrobial products, the labeling must identify the type and 
    level of antimicrobial activity demonstrated by efficacy testing. A 
    product that does not meet the applicable performance standard of 
    proposed subpart W for a specified level of activity (such as 
    sterilizer, disinfectant, or sanitizer) or type of activity 
    (tuberculocidal, virucidal) may not be identified as such on the label, 
    and, in some cases, will be required to bear a disclaimer to make clear 
    the limitations of product performance.
        Under proposed Sec. 156.440, the applicability of subpart W to 
    antimicrobial products is the same as that in part 152, subpart W. This 
    will clarify that all antimicrobial public health products, not just 
    those meeting the definition of ``antimicrobial pesticide,'' are 
    subject to the efficacy performance and labeling standards. This 
    clarifies the status of food use antimicrobials, which are excluded 
    from the statutory definition, but covered under EPA's proposed rule.
        However, proposed Sec. 156.440 would limit applicability of subpart 
    W to end use products. EPA does not expect manufacturing use products 
    to make specific public health claims. Typically a manufacturing use 
    product must be supported by presumptive efficacy testing demonstrating 
    that the active ingredients are capable of antimicrobial activity. The 
    labeling typically bears information on the results of these screening 
    or presumptive efficacy tests. End use products must, however, be 
    supported by specific efficacy data on the end use formulation, on the 
    sites and under the expected conditions of use of the product itself. 
    The performance standards on which the labeling standards of subpart W 
    rely are based upon end use product testing, not presumptive testing of 
    manufacturing use products. The labeling statements and limitations 
    therefore would also relate only to end use products.
        Proposed Sec. 156.441 contains pertinent definitions, including the 
    levels of antimicrobial activity that are permitted on labeling (e.g., 
    sterilizer, disinfectant, sanitizer). This listing is not necessarily 
    exhaustive; in the future, EPA may define additional categories of 
    antimicrobial activity or public health pesticides.
        Proposed Sec. 156.443 describes what types of claims EPA considers 
    to be public health claims. In general, public
    
    [[Page 50700]]
    
    health claims encompass three types of claims: (1) Claims of control of 
    specific microorganisms that are pathogenic to man; (2) claims of 
    levels of antimicrobial activity that are associated with public health 
    protection (e.g., disinfect), even if specific organisms are not named; 
    and (3) claims that make non-specific assertions relating to impact on 
    public health or safety, e.g., ``provides a germ-free environment.'' 
    The use of such terms on a product label is deemed to bring a product 
    within the ambit of FIFRA regulation as a public health product.
        Among the last, EPA has specifically included reference to the term 
    ``sanitary'' as an antimicrobial public health claim. EPA believes that 
    this is a logical extension of the term ``sanitize,'' that should be 
    considered to bring a product under FIFRA regulation as a public health 
    pesticide. EPA regards a product that claims to ``create a sanitary 
    environment'' or is intended to achieve ``sanitary'' effects beyond 
    itself to be making an assertion of impact on public health. The 
    presence of such a claim would clearly constitute a pesticide claim.
        At the same time, EPA recognizes that the term ``sanitary'' may be 
    used on a product in the more traditional sense of ``hygienic,'' i.e., 
    to convey the fact that the product is clean or has been treated to 
    render it free of harmful organisms (for example, ``sanitary'' 
    napkins). When used in such a sense, EPA believes that there is no 
    intent or claim that the product will have an antimicrobial function 
    beyond protection of itself. In the absence of an express claim, EPA 
    proposes to consider the claim ``sanitary'' as an implied pesticide 
    public health claim, and the product on which it appears as a pesticide 
    subject to FIFRA, if: (1) The product composition is similar to other 
    products registered under FIFRA that make antimicrobial claims; or (2) 
    the product contains a substance that is capable of antimicrobial 
    activity at the levels in the product and there is no other functional 
    reason for the ingredient to be present in the product. The burden 
    would be on the producer of a product that makes a ``sanitary'' claim 
    to demonstrate that the claim is not a public health claim. EPA seeks 
    comment as to whether its interpretation of ``sanitary'' claims is 
    sufficiently clear to unambiguously delineate pesticide products or 
    whether it could be overly broad and draw inappropriate products under 
    FIFRA.
        Proposed Sec. 156.444 lists examples of specific antimicrobial-
    related claims that EPA considers to be unacceptable because they are 
    misleading. These are an extension and clarification of existing 
    prohibitions against false and misleading statements found in 
    Sec. 156.10(a)(5). Again, the listings are intended to be exemplary; 
    EPA may determine on a case-by-case basis that a label statement or 
    claim is misleading.
        A product that bears a public health claim, but which does not meet 
    the performance standard for that claim in subpart W would be 
    considered misbranded under FIFRA section 12(a)(1)(E). Registrants have 
    been on notice of the unacceptability of these statements from previous 
    and current Agency guidelines and policies. On the effective date of 
    the final rule, EPA would prohibit these claims from appearing on new 
    products. To ensure that all registrants of current produts are 
    provided adequate notice and have ample opportunity to evaluate their 
    label statements and delete or modify those that are unacceptable, EPA 
    proposes to permit registrants a 1 year period in which to modify 
    labeling before the Agency would find the products to be misbranded. As 
    of a date approximately 1 year after the effective date of the rule, 
    the actual date to be specified in the final rule, EPA may take action 
    against any product that it determines is misbranded based upon the 
    criteria in proposed Sec. 156.444. EPA requests comments on whether a 1 
    year period for label compliance is adequate. Based on comments, EPA 
    may in the final rule adopt a compliance date of more or less than 1 
    year.
        The remainder of subpart W (Secs. 156.445 through 156.458) 
    describes the performance standards and acceptable claims that may be 
    made for various antimicrobial public health pesticides. Each section 
    generally contains the following:
        1. The performance standard for a level of antimicrobial efficacy 
    on a specified site (e.g., sanitizing claim on hard surfaces) or, 
    alternatively, a description of a use site and the performance 
    standards that apply (e.g., fabrics and textiles, air sanitizers).
        2. A reference to the appropriate Guideline for an acceptable test 
    protocol. The performance standards are based upon testing in 
    accordance with the test methods of the Pesticide Assessment 
    Guidelines, Subdivision G, or ``its equivalent.''
        The term ``equivalent'' is defined in Sec. 156.441 to mean a 
    protocol or method that accomplishes the purposes of the cited 
    Guidelines, and that provides data equal in quality and completeness 
    for EPA assessment as that of the cited Guideline. With respect to 
    antimicrobial protocols, an equivalent protocol or method must be 
    validated by multiple laboratories studies that demonstrate 
    equivalency. The term ``Guidelines'' is defined to include both the 
    Pesticide Assessment Guidelines, Subdivision G, and the OPPTS 
    Harmonized Guidelines. For antimicrobial efficacy testing, these differ 
    only in the numbering and formatting of the Guidelines. Ultimately, the 
    OPPTS Guidelines are intended to supersede the OPP Guidelines. EPA 
    expects the Harmonized Guidelines to be issued before the rule is 
    promulgated. Therefore, in proposed subpart W we have included 
    references only to those updated Guidelines. A copy of the latest draft 
    of the Harmonized Guidelines for Antimicrobial Performance (810 series) 
    is included in the public docket. If the Harmonized Guidelines are not 
    final and available at the time of promulgation, EPA will substitute 
    references to the existing Pesticide Assessment Guidelines in the final 
    rule.
        3. A statement of the acceptable claim(s) that may be made on 
    labeling of a product that meets the performance standard. Typically, 
    explicit terminology or wording is provided, which must be used to 
    ensure uniformity of claims. In this respect, Sec. 156.442 would 
    clarify that EPA requirements for specific terminology also authorize 
    grammatical variations on that terminology, or its use in statements 
    and phrases. For example, when EPA specifies that an acceptable claim 
    is as a ``tuberculocide,'' a product would be permitted to use the term 
    ``tuberculocidal'' in a statement or phrase describing the activity of 
    the product.
        4. Any restrictions or limitations upon use of the claim. For 
    example, proposed Sec. 156.455 states that an air sanitizer must bear a 
    statement that accurately describes the limited nature of the 
    sanitizing claim.
        5. In some cases, a description of unacceptable claims. Generally, 
    both restrictions on claims and unacceptable claims are needed to 
    ensure that users, who may have broader expectations of efficacy than 
    the product demonstrates and the labeling conveys, are fully informed 
    of product limitations. For example, proposed Sec. 156.455 specifies 
    that an air sanitizer may not make claims as a sterilant, disinfectant 
    or germicide.
        Proposed subpart W does not contain all required use directions for 
    antimicrobial public health products. It contains only the specific 
    performance standards and closely related restrictions and limitations 
    on labeling claims derived from those standards. Adequate use 
    directions for achieving expected efficacy require detailed 
    instructions that vary depending on the type of product, use site and 
    target
    
    [[Page 50701]]
    
    organism, and must be determined on a case-by-case basis. Particularly 
    for antimicrobial pesticides, use instructions must reflect very 
    specific test parameters keyed to sites of use. For example, the 
    presence of soil or moisture on a surface may affect the ability of a 
    product to perform, and must be accounted for both in efficacy testing 
    and in labeling use directions. These more detailed use instructions 
    are contained in Subdivision H, Labeling Requirements for Pesticide Use 
    Directions, Antimicrobial Products.
    
    XIII. Other Labeling Revisions
    
    A. Use Dilution Labeling
    
        FIFRA section 3(c)(9)(D) provides that antimicrobial products that 
    are or may be diluted for use may bear a different ``statement of 
    caution or protective measures'' for the recommended diluted solution 
    than for the concentrate, provided that adequate data have been 
    submitted to support the proposed statement and the label provides 
    adequate protection for exposure to the diluted solution of the 
    pesticide. The Agency has developed policy and procedural guidance 
    pertaining to use dilution labeling, and will apply the policy to all 
    pesticide products, not just antimicrobial products as required by 
    FIFRA. Today's proposal would modify current regulations in part 156 to 
    provide specifically for use dilution labeling.
        1. Data requirements. EPA intends to specify in a future part 158 
    proposal the data required to support use dilution labeling for 
    antimicrobial products.
        The data needed to support use dilution labeling changes consist of 
    data on acute toxicity of the diluted product. If a product is diluted 
    with water, systemic toxicity (acute oral or dermal toxicity) 
    categorization can be supported by calculations from the concentrated 
    product. In general, systemic toxicity categories differ by a factor of 
    10. Therefore, in most cases, if dilutions are an order of magnitude or 
    more, the toxicity category for a particular route of exposure can be 
    expected to be the next lower category (Category I is highest). For 
    example, if the concentrated product toxicity category is II and the 
    product as used is diluted at least 10-fold, the diluted product should 
    be in toxicity category III; if it is diluted more than 100-fold, the 
    diluted product should be in toxicity category IV.
        On the other hand, label statements triggered by skin or eye 
    irritation or dermal sensitization must be supported by new or cited 
    studies. Calculations are not acceptable because irritation and 
    sensitization effects do not necessarily correlate directly with the 
    degree of dilution.
        In some cases, a diluted product may be more irritating than the 
    concentrated product. Data may be cited if another registered product 
    (such as a ready to use formulation) with a composition similar to the 
    diluted product is supported by acceptable data. In all cases in which 
    the diluent is other than water, data must be submitted, since diluents 
    other than water may themselves be toxic.
        2. Permitted use dilution labeling. EPA proposes to expand its 
    current labeling regulations in 40 CFR part 156 to address 
    opportunities for use dilution labeling. Currently Sec. 156.10 requires 
    that a product be labeled with information on the product as 
    distributed and sold. The product that is marketed to users may be a 
    concentrate product with directions for use dilution, or may be a 
    ready-to-use product requiring no dilution. In many cases, a 
    concentrate product as diluted will be substantially similar in 
    composition and hazards to a ready-to-use product. It makes sense, 
    then, that registrants should be permitted to provide additional 
    information on precautions and protective measures for the diluted 
    product. At the same time, the addition of statements appropriate for 
    the product as diluted should not be allowed to detract from or mislead 
    the user as to the hazards of the product in its undiluted form.
        EPA believes that the ``statement of caution or protective 
    measures'' referred to in FIFRA section 3(c)(9)(D) includes the first 
    aid or practical treatment statement, the human (and animal) 
    precautionary statements, and various personal protective equipment 
    statements. EPA believes that a ``statement of caution'' does not 
    extend to the signal word (DANGER, WARNING, or CAUTION), word POISON 
    and skull and crossbones, or child hazard warning (``Keep Out of Reach 
    of Children''), which should reflect and alert users to the typically 
    higher hazards associated with the concentrate product.
        If the labeling allows a range of dilution, EPA would permit use 
    dilution labeling only for the most concentrated dilution. EPA believes 
    that there is little value in multiple sets of precautionary statements 
    reflecting various levels of use dilution, and that product users would 
    find multiple statements cluttering and confusing.
        Because the concentrate product typically presents higher hazards 
    than the diluted product, EPA would not permit dilution-based 
    statements either to substitute for or modify existing statements for 
    the concentrate product. Rather, EPA would permit additional statements 
    that augment the information for the concentrate product to appear 
    following the concentrate product information. For example, the wording 
    in italics could be added to precautionary or first aid statements:
    
        HAZARDS TO HUMANS. ``Causes substantial but temporary eye 
    injury. Do not get in eyes or on clothing. Wear goggles or face 
    shield. Wash thoroughly with soap and water after handling. Wash 
    contaminated clothing before reuse. After product is diluted, 
    goggles or face shield are not required.''
        FIRST AID. ``If on skin: Take off contaminated clothing. Rinse 
    skin immediately with plenty of running water. Call a doctor or 
    poison control center for further treatment advice. If diluted 
    product gets on skin, medical attention is not required.''
    
        Separate statements could also be used, with appropriate headings 
    for ``Concentrate'' and ``Diluted product'' or similar wording.
    
    B. Reorganization of Labeling Regulations
    
        EPA proposes to reorganize Sec. 156.10(h), which describes labeling 
    requirements pertaining to hazard statements, to upgrade its structure. 
    EPA believes that this long overdue reorganization is needed to 
    accommodate the new use dilution provisions, and to improve the 
    readability of the human hazard and precautionary sections of its 
    labeling regulations. Ultimately EPA intends to upgrade part 156 
    entirely, but at present is doing so only as part of other regulatory 
    proposals that affect labeling.
        EPA has already proposed to upgrade the structure of its use 
    direction labeling requirements as part of its proposal on Pesticides 
    and Ground Water State Management Plans (June 26, 1996; 61 FR 33260). 
    That proposal would create subpart G to contain directions for use.
        Today's proposal carries this organizational upgrading one step 
    further. EPA proposes to create new subpart D in part 156 (comprising 
    Secs. 156.60 through 156.79), and locate in it all human hazard and 
    precautionary statements, including physical and chemical hazards. 
    Environmental hazard and precautionary statements, currently located in 
    Sec. 156.10(h)(2)(ii) would be located in new subpart E.
        In reformatting, EPA has reworded the provisions of current 
    Sec. 156.10(h) for clarity, and is proposing several minor changes:
        1. Section 156.64 would eliminate the requirement that a product in 
    Toxicity
    
    [[Page 50702]]
    
    Category IV by all routes of exposure bear a signal word. Currently, 
    products in Toxicity Categories III and IV bear the same signal word, 
    CAUTION. Products in Toxicity Category IV are of minimal toxicity, and 
    EPA believes that a signal word is not necessary for effecting the 
    purposes for which the product is intended. Indeed, the same signal 
    word for two different categories of toxicity may contribute to 
    misunderstanding of the hazards of products in both categories.
        In recent research conducted under the Consumer Labeling 
    Initiative, users of several types of consumer products tended to 
    ascribe a higher level of hazard to products bearing the signal word 
    CAUTION than to products bearing no signal word at all. Thus the signal 
    word CAUTION on a Category IV product has the potential to be 
    misunderstood. Users may consider all products bearing the signal word 
    CAUTION as similar in toxicity, even though those in Toxicity Category 
    IV pose negligible hazard while those in Category III pose moderate but 
    real hazards.
        The hierarchical Toxicity Category scheme is designed to allow 
    distinctions to be made among products based on acute toxicity. Signal 
    words assigned to the four toxicity categories are intended to allow 
    users to make informed choices about the risks of the products they 
    purchase. Having the same signal word for two categories runs counter 
    to this goal. The hierarchy of product toxicity would be easier to 
    convey on labeling if each category were clearly differentiated from 
    another. Absent a new signal word to assign to Toxicity Category IV 
    products, EPA proposes to eliminate the signal word entirely. The label 
    would still be required to bear the child hazard warning.
        2. Section 156.66 would clarify that the child hazard warning, 
    ``Keep Out of Reach of Children'' is not always appropriate for all 
    products, and that EPA may require or permit an alternative wording of 
    the statement. This change would codify existing policy.
        3. Section 156.68 would require the heading ``First Aid,'' instead 
    of the currently required ``Practical Treatment,'' for the statement 
    regarding emergency treatment by a user to mitigate pesticide 
    exposures. This change was recommended in the Consumer Labeling 
    Initiative Phase I Report (September 30, 1996), in which consumer 
    interviews identified label improvements for consumer pesticide and 
    non-pesticide products.
        4. Section 156.68 would also require that a first aid statement 
    appear on the front panel of the label for each product in Toxicity 
    Category I, including for the first time eye and skin irritation 
    effects. Currently, the statement is required on the front panel only 
    for products in Toxicity Category I based upon systemic effects.
        EPA believes that the current distinction between systemic and 
    irritation effects is not justified. The corrosive effects associated 
    with exposure to a Toxicity Category I skin or eye irritant are 
    potentially irreversible, and EPA believes that information on 
    mitigating those effects should be clearly and immediately available to 
    the user. Logically, then, first aid measures for skin irritation 
    should be as prominently located on the label as those for dermal 
    toxicity. Location on the front panel affords the greatest prominence 
    to first aid statements.
        5. In creating new subpart E in which to locate environmental 
    hazard and precuationary statements, EPA has included in a general 
    section (Sec. 156.80) introductory language describing the location and 
    type size of environmental hazards statements. Otherwise the 
    requirements are the same as those in current Sec. 156.10(h), and 
    comment is not requested on this reorganization.
    
    C. Updated Toxicity Categories
    
        EPA had intended to propose to update its current Toxicity 
    Categories for acute hazard labeling. The Toxicity Categories in 
    Sec. 156.10(h) were established in 1975 and are no longer current. In 
    September 1998, however, the United States agreed in principle with the 
    Organization for Economic Cooperation and Development to harmonize 
    internationally the classification systems for a number of hazard 
    criteria, including acute toxicity. The proposed classification scheme 
    differs markedly from EPA's current scheme, both in the number of and 
    criteria for acute toxicity categories. Implementation plans for the 
    new scheme are intended to be developed by the year 2000.
        In light of the proposed internationally harmonized scheme, EPA has 
    decided not to propose to update its toxicity categories. At best, 
    updating would be an interim step, which would be superseded in 2 to 3 
    years by U.S. implementation of the new scheme, which itself will be a 
    major undertaking for the pesticide industry.
    
    XIV. Chemical Sterilants
    
    A. Liquid Chemical Sterilants Excluded by Statute
    
        FIFRA section 2(u) specifically excludes from the definition of 
    ``pesticide'' liquid chemical sterilants (and their subordinate 
    disinfectant claims) for use on a critical or semi-critical device. 
    This change in FIFRA was effective on August 3, 1996, and supersedes 
    the interim guidance outlined in PR Notice 94-4 (June 30, 1994). That 
    notice pertains to registration procedures for liquid chemical 
    sterilant products affected by the June 3, 1993 Memorandum of 
    Understanding (MOU), as amended, between EPA and FDA. In accordance 
    with the MOU, EPA was preparing a rule to exempt such products from 
    FIFRA regulation under section 25(b), which would have yielded 
    regulatory jurisdiction solely to FDA. That proposal is no longer 
    needed since the jurisdictional change was accomplished statutorily.
        The effect of the exclusion under FIFRA is that such products are 
    regulated solely by FDA as ``devices'' as defined in section 201 of the 
    FFDCA. EPA has issued a notice to registrants of affected sterilant 
    products (PR Notice 98-2, January 15, 1998), informing them of the 
    change in regulatory jurisdiction. Today's proposal will codify in new 
    Sec. 152.6 the statutory exclusion for liquid chemical sterilants, 
    though codification is merely a convenience for the regulated community 
    and is not necessary for the exclusion to be effective.
        Codification of the liquid chemical sterilant exclusion does not 
    change the interim measures outlined in PR Notice 94-4 for general 
    purpose disinfectants, nor does it affect liquid chemical sterilant 
    products intended for use on non-medical devices, such as those 
    intended for use solely on environmental surfaces, or those which are 
    intended for veterinary purposes.
    
    B. Non-liquid Chemical Sterilants Exempted by Regulation
    
        EPA proposes further to use its authority under FIFRA section 25(b) 
    to exempt from FIFRA regulation the following additional antimicrobial 
    product types: (1) Non-liquid chemical sterilants for use on critical/
    semi-critical devices, except ethylene oxide; (2) non-liquid chemical 
    sterilants bearing, in addition, subordinate disinfectant claims for 
    use on critical/semi-critical devices.
        FQPA modified the definition of ``pesticide'' in FIFRA section 2(u) 
    so as to grant FDA exclusive jurisdiction over
    
    [[Page 50703]]
    
    liquid chemical sterilants for use on critical/semi-critical devices. 
    Congress did not, however, address non-liquid chemical sterilants, 
    which have similar uses as liquid chemical sterilants. In fact, under 
    FFDCA section 510, FDA regulates all chemical sterilants used on all 
    medical devices, not just liquid chemical sterilants on critical and 
    semi-critical devices. In modifying FIFRA, Congress affirmed that FDA 
    jurisdiction under FFDCA section 510 was an adequate means of 
    regulating these sterilant products, and that dual oversight with EPA 
    was unnecessary to protect the public health.
        FIFRA section 25(b) authorizes EPA, by regulation, to exempt a 
    pesticide from any or all provisions of FIFRA if the pesticide is 
    adequately regulated by another Federal agency. EPA believes that 
    Congress' expression of the adequacy of FDA's approval process for 
    liquid chemical sterilants and their subordinate disinfection claims on 
    critical/semi-critical devices as a statutory matter is an adequate 
    basis for EPA to determine that non-liquid chemical sterilant products 
    regulated under the same approval process are adequately regulated by 
    another Federal agency.
    
    C. Antimicrobial Products Neither Excluded nor Exempted
    
        1. Any claims on non-critical medical devices. EPA does not propose 
    to exempt sterilants or disinfectant products used on non-critical 
    medical devices from FIFRA regulation. Non-critical medical devices 
    potentially cover a wide array of items and surfaces, such as blood 
    pressure cuffs and bedpans. EPA and FDA currently share jurisdiction 
    over products used on non-critical medical devices. However, under its 
    1993 MOU with FDA, EPA and FDA agreed to an approach under which FDA 
    would grant sole responsibility for products used on non-critical 
    medical devices to EPA. FDA has issued a proposal to exempt general 
    purpose disinfectant products from the requirement for pre-market 
    clearance under FFDCA section 510(k) (63 FR 59917, November 6, 1998).
        2. Any claims on non-medical devices. EPA has sole jurisdiction 
    over all claims on non-medical devices. These products are not 
    regulated jointly with FDA.
        The combination of the statutory exemption for liquid chemical 
    sterilants and the exemptions proposed under FIFRA section 25(b) would 
    give FDA sole jurisdiction over all chemical sterilants (except 
    ethylene oxide), together with their subordinate level disinfection 
    claims for use on all critical and semi-critical medical devices. 
    Exempting from FIFRA coverage additional sterilants and uses and 
    consolidation of regulatory jurisdiction with FDA will eliminate dual 
    regulatory requirements and unnecessary paperwork requirements.
        Table 5 below sets out concisely the status of chemical sterilants 
    and other antimicrobial products used on medical devices, and the 
    statutory and regulatory transfers that are occurring for liquid and 
    non-liquid chemical products. Where the table indicates ``no change'' 
    in the last column, the jurisdiction has not changed by statute, and 
    EPA is not proposing any regulatory change.

    ----------------------------------------------------------------------------------------------------------------
    
    D. Ethylene Oxide
    
        Ethylene oxide is a gaseous form of sterilant, and thus was not 
    transferred to FDA jurisdiction by statute. EPA does not propose to 
    exempt the sterilant ethylene oxide because, in contrast to the other 
    non-liquid sterilants that would be exempted, ethylene oxide use is not 
    limited to medical and hospital use. Ethylene oxide is used as a 
    fumigant for foods, particularly for fumigation of whole spices, a use 
    regulated by no other Agency except EPA. Thus, even if EPA were to 
    exempt the ethylene oxide sterilization use on critical/semi-critical 
    devices, EPA might retain significant oversight over ethylene oxide for 
    other uses. It makes sense, then, for EPA to retain jurisdiction over 
    the sterilant use of ethylene oxide on medical devices.
    
    XV. Nitrogen Stabilizers
    
    A. Nitrogen Stabilizers are Regulated as Pesticides
    
        FQPA expanded the FIFRA definition of ``pesticide'' to include 
    nitrogen stabilizers, but by definition in FIFRA section 2(hh) 
    ``nitrogen stabilizer'' excludes certain substances. Two named 
    substances (dicyandiamide and ammonium thiosulfate) are excluded 
    outright. Other substances are excluded
    
    [[Page 50704]]
    
    if they meet the criteria in section 2(hh)(3): They were introduced 
    into commercial agronomic use by January 1, 1992, without being 
    registered under FIFRA, and thereafter have not made specific claims of 
    ``prevention or hindering of nitrification, denitrification, ammonia 
    volatilization [or] urease production'' (collectively referred to in 
    this discussion as ``nitrogen stabilization claims''), except where 
    required to do so under State pesticide regulations.
        EPA proposes to add to new Sec. 152.6 those substances that are not 
    nitrogen stabilizers by statutory definition and therefore not 
    regulated as pesticides when used for nitrogen stabilization purposes. 
    All other nitrogen stabilizer products are regulated as pesticides 
    under FIFRA. This unit discusses how EPA will determine which nitrogen 
    stabilizers it will treat as pesticides.
    
    B. What is a Nitrogen Stabilizer?
    
        1. Action on soil bacteria. To be a nitrogen stabilizer in the 
    first instance, a product must accomplish the purpose of nitrogen 
    stabilization through ``action upon soil bacteria.'' Clearly, this 
    phrase excludes fertilizer products, which increase soil nitrogen by 
    simple addition of nitrogen-containing substances rather than any soil 
    bacterial action. However, any product that enhances soil nitrogen 
    availability by affecting the soil bacteria is a nitrogen stabilizer, 
    regardless of whether it also functions as a fertilizer after action on 
    soil bacteria. Such dual products that function both as nitrogen 
    stabilizers and fertilizers are regulated under FIFRA if they meet the 
    other statutory criteria for nitrogen stabilizers.
        2. Date of introduction into commerce. The first criterion pertains 
    to the date of introduction of the product into commerce. Section 2(hh) 
    specifies January 1, 1992, as the date before which the product must 
    have been in ``commercial agronomic use'' but not registered as a 
    pesticide (as well as the date after which no specific claims of 
    nitrogen stabilization must have been made in connection with its sale 
    and distribution; see below). EPA can verify from its records what 
    products were registered before January 1, 1992 (these are nitrogen 
    stabilizers that must continue to be registered). EPA interprets 
    ``commercial agronomic use'' to mean that a product is being 
    distributed and sold at the wholesale and retail levels. A product that 
    is being distributed only in a limited or restricted way in preparation 
    for full marketing is not considered to have achieved commercial 
    marketing status.
        3. Specific claims. The second criterion relates to claims made for 
    the product. The statute does not define what is meant by a ``specific 
    claim of prevention or hindering of the process of nitrification, 
    denitrification, ammonia volatilization [or] urease production.'' 
    Moreover, there is no explanatory legislative history to guide EPA in 
    discerning Congressional intent. Therefore, EPA is interpreting the 
    phrase in a common sense manner.
        Nitrification, denitrification, ammonia volatilization, and urease 
    production denote specific undesirable actions of soil bacteria with 
    the result that nitrogen availability is decreased. Clearly, any 
    product that uses these terms on the label is making a ``specific 
    claim'' of mitigating that effect. However, other claims which focus 
    only on the end result of nitrogen stabilization (increased/prolonged 
    availability of nitrogen) are also used on product labels. EPA 
    identifies examples of these phrases in proposed Sec. 152.6(b)(4). The 
    phrases listed in that section, to the Agency's knowledge, could be 
    used to describe only two functions of products--either the fertilizer 
    effect of addition of slow-release nitrogen-containing substances, or 
    the pesticidal effect on soil bacteria that is nitrogen stabilization 
    and has the same end result.
        Although these label claims could theoretically be used to describe 
    fertilizers, EPA believes that they are in practice claims of nitrogen 
    stabilization rather than fertilizer claims, for the following reasons. 
    First, fertilizer products are already excluded from FIFRA regulation 
    by EPA's own regulations in Sec. 152.8, and a fertilizer product need 
    only be labeled as such (and bear no other pesticide claims) to avoid 
    FIFRA regulation. It would make little sense for a fertilizer product 
    to bear claims such as ``increases nitrogen uptake'' or ``prolongs 
    nitrogen availability'' when a simple declaration as a ``fertilizer'' 
    would suffice under FIFRA, and ``fertilizer'' is a description of such 
    a product that would be understood by all purchasers. The only other 
    plausible use of these ambiguous claims relates to nitrogen stabilizing 
    effects on soil bacteria.
        More telling is EPA's experience in evaluating such products. A 
    first-hand examination of the labeling and ingredients declaration of a 
    product is the most reliable method to determine if products with such 
    claims are to be regulated under FIFRA. An examination of this sort is 
    similar to the process used for many years to determine the pesticide/
    non-pesticide status of plant regulators (pesticide) versus fertilizer 
    (non-pesticide) products. In each instance that EPA has examined a 
    product bearing a claim such as described in Sec. 152.6(b)(4), EPA has 
    determined that the product was, in fact, functioning as a nitrogen 
    stabilizer, and that the product composition was consistent with an 
    expected nitrogen stabilization purpose rather than, or in addition to, 
    a fertilizer purpose.
        Moreover, such an interpretation of indirect claims is in keeping 
    with EPA's past and current policies on nitrogen stabilizers. EPA's 
    policy has been to treat claims that indicate pesticidal intent as 
    pesticide claims that subject the products to regulation under FIFRA. 
    Therefore, EPA proposes to treat any claim that states or implies that 
    the product will prevent or hinder nitrification, denitrification, 
    ammonia volatilization, or urease production as a claim that brings the 
    product under the purview of FIFRA as a nitrogen stabilizer. If a 
    product functions solely as a fertilizer or a slow- or delayed-release 
    fertilizer, is labeled as such with explanatory information on the 
    method used to accomplish any delayed- or slow-release action (e.g., by 
    encapsulation) and bears no additional claims that appear to be 
    nitrogen stabilization claims, it would not be considered a pesticide.
        EPA believes that to do otherwise would create an administrative 
    and enforcement inequity that could potentially undermine the intent of 
    the statute to the point where it would have little practical effect. 
    The purpose of incorporating nitrogen stabilizers into the definition 
    of ``pesticide'' in FIFRA section 2(u) is to regulate certain nitrogen 
    stabilizers as pesticides. If EPA were to interpret the Act to limit 
    the regulatory coverage of nitrogen stabilizers to products that use 
    the magic words ``nitrification,'' ``denitrification,'' ``ammonia 
    volatilization,'' or ``urease production,'' while ignoring other 
    language that makes equivalent but differently phrased claims, a 
    product that Congress intended to be regulated could escape FIFRA 
    regulation merely by using a ``code phrase'' that conveys the same 
    meaning as these terms. Arguably, under such a restrictive 
    interpretation, the only nitrogen stabilizers covered by FIFRA might be 
    those already registered as of January 1, 1992. EPA believes that 
    Congress could not have intended to extend coverage of FIFRA to 
    nitrogen stabilizers, only to exclude most or all of those products by 
    a mere turn of phrase.
        4. State exclusion. Congress did provide a specific exclusion for 
    statements that are required by State
    
    [[Page 50705]]
    
    legislative or regulatory authorities. A product that makes a claim of 
    nitrogen stabilization in its labeling or other materials only because 
    of a State requirement is not thereby brought under FIFRA regulation. 
    Congressional intent is clear: Federal regulatory authority over 
    nitrogen stabilizers should not be enlarged by actions of the States. 
    Nor does EPA believe that Congress intended that a product that 
    triggered Federal regulation by making nitrogen stabilizer claims be 
    removed from regulation by subsequent action of a State. Proposed 
    Sec. 152.6 therefore makes clear that the State requirement for 
    labeling must be a pre-existing one, that is, in place prior to the 
    assertion of nitrogen stabilizing claims by the seller or distributor.
        Moreover, a product for which nitrogen stabilization claims are 
    made because of a State requirement is nonetheless subject to FIFRA 
    regulation if at any time since January 1, 1992, nitrogen stabilization 
    claims have been made for the product with respect to its distribution 
    and sale in another State that does not have such a requirement. Sale 
    or distribution of such a product in any State, including the State 
    which imposed the labeling requirement, is subject to the provisions of 
    FIFRA.
        The producer of a product who claims eligibility under this 
    exclusion would need to maintain sufficient records to clearly 
    demonstrate that, as of January 1, 1992, the product was being 
    commercially distributed and sold (sales records, for example), and 
    that no nitrogen stabilization claims were made after that date (dated 
    copies of labeling and advertising, for example). These records are 
    maintained by producers as a normal business practice, so no additional 
    recordkeeping would be required by this proposal.
    
    XVI. Notification of Registration Changes
    
    A. FQPA Modifications
    
        EPA proposes to modify its current notification procedures for 
    antimicrobial products to conform to those established under FIFRA 
    section 3(c)(9). The statutory provisions requiring these changes are 
    discussed in Units IV.I. and V.B.
        Prior to FQPA, FIFRA did not provide a notification scheme. In 
    1988, EPA implemented a regulatory notification framework (contained in 
    Sec. 152.46), under which EPA determines acceptable modifications to 
    registration that may be made by notification. The types of acceptable 
    notifications are set out in direct notices to registrants, together 
    with the procedures for submitting notifications.
        FQPA modified FIFRA with respect to notifications for antimicrobial 
    pesticides only, in both substance and procedure. For the first time, 
    FIFRA establishes a statutory right for antimicrobial registrants to 
    make certain types of changes by notification. Specifically, a 
    registrant may modify the labeling of an antimicrobial pesticide 
    product to include relevant information on product efficacy, product 
    composition, container composition or design or other characteristics, 
    that do not relate to any pesticide claim or pesticidal activity. 
    Further, FIFRA sets up a procedure for antimicrobial notifications that 
    holds both registrants and EPA to a high degree of accountability.
        FIFRA section 3(c)(9) became effective on August 3, 1996; today's 
    proposal would codify the procedures of the Act that are already in 
    effect. Neither current regulations nor this proposal address the types 
    of actions that may be accomplished by notification.
        The notification provisions of the Act apply only to antimicrobial 
    products. As a policy matter, EPA could extend both the types of 
    notifications and the procedures for notifications to other products. 
    After consideration, EPA has decided to allow non-antimicrobial 
    registrants to avail themselves of the new types of notifications 
    provided by FIFRA section 3(c)(9), but will not propose changes in its 
    current procedures for notifications for such products. Although EPA 
    believes that the new statutory process for antimicrobials is superior 
    in some ways to the existing notification scheme, it is reluctant to 
    add an additional procedural layer to a system that appears to work 
    well as currently administered.
        Consequently, after the effective date of the rule, EPA would have 
    in place two notification schemes (antimicrobials/other pesticide 
    products), but would have a unified set of notification actions. After 
    the effective date of the rule, antimicrobial registrants would be 
    required to follow the notification procedures of Sec. 152.446 only; 
    they would not be permitted to follow the current procedures in 
    Sec. 152.46. EPA welcomes comment on whether the notification 
    procedures for antimicrobials should be adopted across-the-board. If 
    persuaded by commenters that there are benefits without undue costs in 
    making the procedures for notifications uniform for all products, EPA 
    could, in the final rule, adopt the procedures across-the-board. If it 
    does so, EPA would simply adopt the provisions of Sec. 152.446 to 
    replace those currently in Sec. 152.46.
        Although EPA does not propose to apply the new procedures to all 
    products, it believes that the types of notifications permitted by 
    FIFRA section 3(c)(9) should be extended to all products rather than 
    limiting them to antimicrobials. Doing so does not require that EPA 
    modify its regulations in Sec. 152.46, since permitted notifications 
    are detailed in direct notices to registrants (PR Notices), a practice 
    EPA would continue. Current permitted notifications are specified in PR 
    Notice 98-10, issued October 22, 1998.
    
    B. Comparison of Current and New Procedures for Antimicrobial Products
    
        This unit describes the new procedures for antimicrobial product 
    notifications and compares them to the current procedures for all other 
    products, which are not proposed for change. The significant 
    differences between antimicrobial procedures and current notification 
    procedures in Sec. 152.46 are that:
        1. Registrants who submit antimicrobial notifications must wait 60 
    days after submission before distributing or selling the modified 
    product. Registrants of other products may distribute or sell 
    immediately upon submission.
        The new scheme offers an eminently practical solution for the 
    uncertainties of compliance and enforcement in the current notification 
    process. Under the current scheme, a registrant who ships immediately 
    upon notification runs the risk that EPA might thereafter determine the 
    notification is improper, and the product would be in violation of 
    FIFRA. Because FIFRA section 3(c)(9) prohibits sale and distribution of 
    a modified product for 60 days after submission, but requires Agency 
    action within 30 days, there will always be some period of time after 
    the Agency's decision before an antimicrobial product can be shipped 
    legally. There is no possibility (as exists under the current scheme) 
    that a registrant will ship an antimicrobial product only to have the 
    Agency disapprove the notification. The benefit of certainty is 
    somewhat offset by the fact that an antimicrobial registrant must wait 
    before shipping. However, EPA proposes in Sec. 152.446 to allow 
    shipment at any time after receipt of approval by the Agency (30 days), 
    thereby almost halving the 60-day waiting time.
        2. EPA is obligated to disapprove antimicrobial notifications it 
    finds unacceptable within 30 days after receipt. Under the current 
    process,
    
    [[Page 50706]]
    
    EPA's goal is to make its determination within 30 days, but it is not 
    required to do so.
        The new process involves some increase in resources and time on 
    EPA's part. Requiring a review and specific disapproval decision within 
    30 days of receipt is more demanding than the current scheme which 
    lacks a decision deadline. Nonetheless, antimicrobial notifications are 
    currently being processed within 30 days, so EPA anticipates little 
    pressure on its current antimicrobial program resources to accommodate 
    the 30-day decision deadline.
        3. EPA may require substantiating information for an antimicrobial 
    notification. Current EPA regulations in Sec. 152.46 do not explicitly 
    mention substantiation. EPA proposes that antimicrobial registrants be 
    required to retain, and submit upon request, substantiating information 
    for each modification. Substantiating information might be required to 
    be submitted if the registrant objected to the Agency's disapproval of 
    his/her notification. The provision for substantiation of claims for 
    antimicrobial products offers EPA greater assurance that the claims are 
    in fact accurate, and can be verified objectively or scientifically.
        4. Antimicrobial registrants may formally object to the Agency's 
    disapproval of an antimicrobial notification. Current Sec. 152.46 
    contains no provision for appeal of an Agency disapproval. The 
    availability of an administrative appeals process, if used frequently, 
    would increase resource needs to administer the process. However, EPA 
    anticipates few appeals since the types of notifications permitted by 
    the statute are relatively straightforward decisions for which the 
    current notification scheme was designed.
    
    XVII. Conforming and Organizational Changes
    
    A. Changes in Definitions
    
        EPA is proposing to modify, delete, or add a number of definitions 
    to Sec. 152.3. Definitions located in Sec. 152.3 apply to all pesticide 
    applications, including antimicrobial applications. The definition of 
    ``pesticide'' would be deleted because it has become so long and 
    complicated in the statute itself that it adds no value to reiterate 
    the definition in regulations. The definition of ``active ingredient'' 
    would be modified to conform to the change made by FQPA adding nitrogen 
    stabilizers. Definitions to be added include the following:
        1. ``Antimicrobial pesticide,'' to allow reference to new subpart 
    W. The definition proposed here interprets the statutory definition to 
    clarify and give practical meaning to the exclusions from the 
    definition for ``wood preservative,'' ``antifouling paint product,'' 
    ``fungicide for agricultural use'' and ``aquatic herbicide.''
        2. ``Applicant,'' ``registrant'' and ``application for 
    registration,'' to create concise terms that cover both new and amended 
    registrations.
        3. ``Complete application.'' This definition is being added to 
    apply to all pesticide applications because a number of FIFRA 
    provisions (not just those for antimicrobial products) depend upon the 
    submission of a ``complete application,'' including: (1) the timeframes 
    for all ``fast-track'' applications under section 3(c)(3)(B); (2) the 
    priority given to review of minor use applications under section 
    3(c)(3)(C); and (3) the priority given to so-called ``safer'' 
    pesticides under section 3(c)(10). For antimicrobial pesticides, 
    Sec. 152.450 contains detailed information on what constitutes a 
    complete application.
        4. ``Fast-track application,'' to formalize the term widely used by 
    the Agency and the regulated community for applications under FIFRA 
    section 3(c)(3).
        5. ``Nitrogen stabilizer,'' to include the statutory term here for 
    convenience.
    
    B. Exclusions and Exemptions under FIFRA
    
        EPA proposes to compile in one location in its regulations the 
    various exclusions that have accumulated in FIFRA over the years. 
    Exclusions from FIFRA regulation are statutorily designated substances 
    that are not to be regulated under FIFRA. Readers should note that 
    ``exclusions'' do not include exemptions granted under FIFRA section 
    25(b), which are pesticides specifically removed from FIFRA regulation 
    by Agency action.
        Several exclusions already exist in FIFRA, and are identified in 
    current regulations. These include:
        1. Substances used against organisms that are not ``pests'' by 
    definition in FIFRA section 2(t).
        2. Substances that are not ``pesticides'' by definition in FIFRA 
    section 2(u).
        3. Substances that indirectly are not ``pesticides'' by virtue of 
    being excluded from definitions of substances that are pesticides, such 
    as ``vitamin-hormone horticultural products,'' which are excluded from 
    the definition of ``plant growth regulator'' in FIFRA section 2(v).
        FQPA amended FIFRA to add two additional exclusions for substances 
    that are not to be regulated under FIFRA. Because the existing 
    exclusions are scattered in FIFRA and have been expanded by FQPA, EPA 
    believes it would be useful and convenient to consolidate them in one 
    location in its regulations. Accordingly, EPA proposes to create new 
    Sec. 152.6 and to include in it both existing and new exclusions.
        Existing exclusions, which have not been altered, include those in 
    Sec. 152.8 for pests of living man and animals (human and animal drugs) 
    and various soil amendment products, in Sec. 152.20 for human drugs and 
    in Sec. 152.25 for vitamin hormone products. New exclusions include 
    those for certain liquid chemical sterilants and certain nitrogen 
    stabilizer products. EPA believes that proposed Sec. 152.6 contains all 
    exclusions provided by statute or existing regulations. If EPA finds 
    that it has inadvertently omitted any exclusions provided by statute, 
    it will in the final rule add them to Sec. 152.6.
    
    XVIII. Consultations During the Development of this Proposal
    
        FIFRA section 3(h) requires that EPA, in developing this proposed 
    regulation, ``solicit the views from registrants and other affected 
    parties to maximize the effectiveness of the rule development 
    process.'' EPA has consulted, and maintains an open dialogue with, a 
    number of interested parties, both in establishing the streamlined 
    antimicrobial program itself and in developing this proposal.
    
    A. Stakeholder Meetings
    
        Stakeholder meetings were begun shortly after enactment of FQPA--
    the first was in November 1996--with a view to engaging the 
    antimicrobial industry (which is largely composed of small businesses), 
    public health, consumer and environmental groups, in discussions and 
    suggestions that could be implemented in the rule. Since then, EPA has 
    held a number of open public meetings, approximately every quarter, to 
    discuss issues arising from the development of the antimicrobial rule 
    and the administration of the antimicrobial registration program. These 
    open meetings have been announced in the Federal Register and have been 
    attended by registrants, trade associations representing antimicrobial 
    producers and users, other Federal agencies, and environmental and 
    consumer groups. Information about the meetings and summaries have been 
    placed in a public docket (OPP docket control number 00473, located at 
    the address given under ADDRESSES). EPA
    
    [[Page 50707]]
    
    intends to conduct further meetings of this nature, and will make 
    special efforts to continue and expand the participation of small 
    businesses in the dialogue fostered through such meetings.
        To enhance pre-proposal input into the regulatory development 
    process, draft language for this proposal was released to the public in 
    April 1997, and again in June 1998. Ensuing discussions and comments 
    raised a number of issues of concern. Among them were the following:
        1. The opportunity to rebut Agency's conditions of registration. 
    When EPA issues a registration, it often does so with conditions 
    attached, generally labeling changes. Registrants have not had the 
    opportunity to have EPA reconsider conditions they believed were 
    onerous or unnecessary. EPA has now modified the proposal to allow 
    applicants who disagree with EPA's imposition of labeling changes as a 
    condition of registration to submit a rebuttal for consideration.
        2. A shorter review period for resubmissions. Industry was 
    concerned that EPA might choose to start its review clock over for 
    minor resubmissions to complete an application or respond to Agency 
    questions. In response, EPA is proposing a specific new category of 
    shortened review period for ``qualifying resubmissions.'' This new 
    category would shorten the review period that would otherwise apply by 
    30 days for applications with review periods of 120 days or less. EPA 
    estimates that approximately 75% of antimicrobial applications each 
    year would have review periods of 120 days or less, and would benefit 
    from this provision.
        3. How EPA would deal with indications of product lack of efficacy. 
    EPA had considered a scheme whereby applicants would agree to accept as 
    a condition of registration the imposition of a variety of measures if 
    their product was found to be inefficacious after registration. 
    Industry was concerned about the vague nature of EPA's proposal, and 
    viewed it as potentially costly. As a result, EPA has scrapped this 
    scheme, and developed a new one (the sunset provision in Sec. 152.458), 
    to respond to their concerns.
    
    B. Workshops
    
        To complement the stakeholder meetings and extend their approach to 
    stakeholder involvement to a larger group of participants, on January 
    8-9, 1997, EPA held a highly successful 2-day antimicrobial regulation 
    workshop attended by over 300 participants. At a number of plenary 
    sessions and small discussion groups, EPA explored with participants 
    issues such as improving and streamlining the registration process for 
    antimicrobial products, self-certification, harmonization with States 
    and the international community, applying for registration, and 
    antimicrobial data requirements. A second workshop was held on June 15-
    16, 1998, and was attended by an even larger group of stakeholders. A 
    major trade association with extensive small business membership was 
    fully represented at both workshops. In addition, individual 
    representatives of more than 15 small firms attended.
    
    C. Food and Drug Administration
    
        FQPA modified both FIFRA and FFDCA in ways that either explicitly 
    or effectively transferred regulatory authority over a number of 
    pesticides between EPA and FDA. As a result, EPA has consulted 
    frequently with FDA in preparing this proposal with respect to liquid 
    chemical sterilants (see Unit. XIV.) and the transfer of regulatory 
    jurisdiction over certain food use antimicrobial residues back to FDA 
    (see Unit XI.).
    
    D. Canada
    
        In the fall of 1996, EPA held discussions with the Pest Management 
    Regulatory Agency of Health Canada, which is the Canadian government 
    agency responsible for regulation of certain antimicrobial pesticides 
    in Canada. These consultations focussed primarily on Canada's system of 
    categorizing antimicrobial pesticide types, its administrative 
    procedures that EPA might adopt to streamline, simplify and accelerate 
    the Agency's procedures, and ways to harmonize data requirements for 
    antimicrobial products.
        Although the majority of the discussions targeted administrative 
    rather than regulatory changes, EPA has included in this proposal 
    expanded application contents (Sec. 152.450) that will, in addition to 
    assisting U.S. regulators of antimicrobial pesticides, foster 
    harmonization of application reviews between Canada and the U.S. For 
    example, the requirement that an applicant supply copies of available 
    data reviews conducted by other countries (such as Canada) will 
    contribute to more efficient regulation of antimicrobial products. In 
    addition, EPA's rigorous application of completeness criteria as a 
    resource management tool mirrors that of Canada.
    
    XIX. Table of Affected Sections
    
        Because today's proposal covers myriad and diverse topics that

    XX. Statutory Review Requirements
    
        In accordance with FIFRA section 25(a), this proposal was submitted 
    to the FIFRA Scientific Advisory Panel, the Secretary of Agriculture 
    (USDA), the Secretary of Health and Human Services (HHS), and 
    appropriate Congressional Committees. The Scientific Advisory Panel 
    waived its review of this proposal.
    
    A. USDA Comments
    
        1. USDA suggested that the document include a discussion of the 
    issues surrounding microbial pest resistance.
    Response: While there is evidence that microorganisms develop 
    resistance to antibiotics, EPA is not aware of evidence that 
    microorganisms are developing resistance to antimicrobial pesticides. 
    Microorganisms respond to biocidal agents, and differ markedly in 
    susceptibility and resistance responses to agents such as disinfectants 
    and antiseptics. Bacterial resistance to biocides is usually considered 
    to be of two types: (1) Intrinsic (a natural property of an organism); 
    or (2) acquired (by genetic mutation or physiological adaptation). The 
    mechanisms of susceptibility and resistance to biocides and techniques 
    that would enhance or reduce susceptibility/resistance are not well 
    understood and would require further research.
        EPA expects that it would become aware of developing microbial pest 
    resistance in public health products either through registrant 
    reporting of lack of efficacy under FIFRA section 6(a)(2) or through 
    the 5-year retesting program. A public health product that failed to 
    demonstrate efficacy at the 5-year mark would be removed from the 
    marketplace by automatic expiration of the registration.
        2. USDA suggested that EPA clarify in the proposal the status of 
    agricultural microorganisms other than fungi, for example, nematodes.
    Response: EPA has revised Unit VI.C. of the preamble and the definition 
    of ``antimicrobial pesticide'' in Sec. 152.3 to clarify that an 
    agricultural fungicide is one applied to crops or plants pre-harvest. 
    It should be noted that nematodes are not considered microorganisms, 
    but invertebrates, and thus would not be included in the definition of 
    antimicrobial pesticide in any case.
        3. USDA suggested that EPA standardize the review processes and 
    times for wood preservatives and antifoulant paints.
    Response: FIFRA section 2(mm) specifically excludes wood preservatives 
    and antifoulant paints from the definition of ``antimicrobial 
    pesticide,'' and thus, with only limited exceptions, also excludes such 
    products from the application review periods that this proposal would 
    establish for antimicrobial pesticides. Therefore, EPA is not proposing 
    to include wood preservatives and antifoulant paints within the scope 
    of this regulation and its review periods. Unit VIII.H.4. contains a 
    full explanation of when the review periods apply to certain wood 
    preservative products. The review periods discussed in that unit, 
    however, do not extend to antifoulant paints.
        As a practical matter, the review processes for all wood 
    preservatives and antifoulant paints are the same regardless of where 
    within the EPA organization they originate. The data requirements and 
    risk assessments for such products are the same and depend on the 
    chemical and the potential risks from its use, regardless of whether 
    there is a statutory review period.
    
    B. HHS Comments
    
        HHS provided informal comments on the draft, many of which were 
    questions, clarifications, or corrections to the proposal. EPA has made 
    changes to the draft proposal in many instances based upon their 
    suggestions. A brief summary of their substantive comments follows.
        1. HHS wanted to know the relationship between ``antimicrobial 
    pesticides'' and ``public health pesticides'' and whether they were 
    treated differently in the proposal.
    Response: Both terms are defined in FIFRA. ``Antimicrobial pesticide'' 
    is defined in FIFRA section 2(mm) to include, among other things, 
    products intended to ``disinfect, sanitize, reduce, or mitigate growth 
    or development of microbiological organisms.'' ``Public health 
    pesticide'' is defined in FIFRA section 2(nn) to include products for 
    the ``. . . prevention or mitigation of viruses, bacteria, or other 
    microorganisms . . . that pose a threat to public health.'' An 
    antimicrobial pesticide may be a public health pesticide if it is 
    intended to destroy or mitigate microoganisms that pose a threat to 
    public health.
        However, there is a single standard for registrability of a 
    pesticide in FIFRA section 3(c)(5), namely that the pesticide itself, 
    or in its intended use, not cause ``unreasonable adverse effects'' on 
    man or the environment, taking into account the economic, social, and 
    environmental costs and benefits of the use of the pesticide. This is a 
    risk/benefit balancing provision. Of significance, though, is that EPA 
    is specifically directed to take into account the health risks posed by 
    the disease vectors controlled by a public health pesticide when 
    weighing its risks and benefits. Under FIFRA section 6(b)(2), when EPA 
    is contemplating action against a public health pesticide based on 
    risk, HHS should provide information on use and benefits to the Agency 
    to inform its risk/benefit decision.
        2. HHS asked about the scope of the proposed rule in relation to 
    HHS activities under FFDCA section 409. HHS noted the statutory 
    definition of ``antimicrobial pesticide'' in FIFRA,
    
    [[Page 50709]]
    
    which excludes pesticides that require a clearance under either FFDCA 
    secton 408 or 409. HHS also noted that ARTCA grants jurisdiction over 
    many antimicrobial pesticide residues in food to FDA (discussed in Unit 
    XI.), but it still requires registration of the pesticides under FIFRA.
    Response: The definition of ``antimicrobial pesticide'' applies only to 
    registration activities under FIFRA; it does not affect activities 
    related to any FFDCA section 409 food additive regulation. EPA has no 
    jurisdiction under section 409. Any action affecting the registration 
    of an antimicrobial pesticide under FIFRA, such as cancellation or 
    expiration under the ``sunset provision,'' would not necessarily 
    require that FDA revise or revoke any food additive regulations 
    associated with that pesticide.
        A similar situation could arise if EPA has established a tolerance 
    or exemption under section 408 for a pesticide whose registration has 
    expired under the sunset provision. As noted in Unit IX, the sunset 
    provision is intended to ensure efficacy of public health products, not 
    to determine whether the tolerance fails to meet the ``reasonable 
    certainty of no harm'' standard of FFDCA. It is unlikely that the 
    cancellation or expiration of any single product registration would 
    trigger action to revoke the tolerance because there likely would 
    remain other products on the market for the same use that are supported 
    by the same tolerance or food additive regulation.
        That said, EPA proposes to include all antimicrobial products in 
    the scope of its proposed regulation. Unit VIII.B contains a full 
    explanation of the applicability of subpart W. Under Sec. 152.441, 
    subpart W applies not only to ``antimicrobial pesticides,'' but also to 
    antimicrobial products whose registration requires a clearance under 
    FFDCA section 408 or 409. Because the proposed rule affects only FIFRA 
    actions, however, the difference in coverage of the statutory term 
    ``antimicrobial pesticide'' and the broader coverage of the proposed 
    rule is not expected to affect HHS activities under FFDCA over those 
    same pesticides.
        3. HHS commented that EPA's proposal would expand the scope of FDA 
    authority over chemical sterilants beyond that agreed to by EPA and 
    FDA.
    Response: EPA has revised the proposal to align its provisions with 
    FDA's understanding of our respective responsibilities (see Unit XIV.).
        4. HHS comments suggested several areas where increased EPA/FDA 
    consultation was desirable or necessary, for example, enforcement of 
    labeling claims for products subject to both EPA and FDA jurisdiction.
    Response: EPA and HHS are in the process of developing a Memorandum of 
    Understanding (MOU) that would address responsibilities and 
    consultations in a number of areas. The MOU is expected to establish a 
    consultative process between the Agencies that will facilitate 
    information exchange and resolution of issues. EPA expects that the 
    consultations undertaken under the MOU will serve the various purposes 
    noted by FDA. Currently EPA consults informally with counterparts in 
    the FDA, the Centers for Disease Control, and other HHS offices on 
    issues of joint authority and mutual interest.
        5. HHS requested that EPA clarify the status under the Freedom of 
    Information Act (FOIA) of data and/or data reviews provided to other 
    agencies if the applicant authorizes EPA to share such data.
    Response: The status of data provided to another agency under a 
    registrant authorization would not change under FOIA because of the 
    data sharing. A request to HHS for the release of such data would be 
    treated the same under FOIA as a request to EPA.
        6. HHS had a number of comments related to the efficacy performance 
    standards (part 156, subpart W).
        a. Virucidal claims. HHS suggested that EPA consider selecting 
    representative viruses with differing intrinsic resistance to 
    antimicrobial chemicals and use those as benchmark viruses for test 
    purposes in support of a general virucidal claim.
    Response: Currently, EPA requires that each specific virus intended to 
    be claimed on the label be tested, and identified on the labeling. EPA 
    takes the position that there is no known data base that assures that 
    all viruses have the same susceptibility or resistance responses to 
    antimicrobial agents, or that allows across-the-board extrapolation of 
    results. Nonetheless, EPA has funded a 3-year research project on the 
    use of surrogate viruses. The results from this study are currently 
    under review.
        b. Efficacy terminology. HHS noted that there are differences in 
    terminology between EPA and HHS performance measures. HHS considers a 
    laboratory test demonstrating product efficacy to be a test of a 
    chemical's ``potency'' and not its ``efficacy.'' HHS believes that 
    ``efficacy'' is demonstrated only in the ability of an antimicrobial 
    agent to reduce or prevent transmission of disease.
    Response: EPA acknowledges these differences. In the case of 
    antimicrobial pesticides, EPA uses the term ``efficacy'' to refer to 
    laboratory testing that demonstrates ``presumptive'' efficacy of a 
    product in reducing microbial populations on environmental surfaces. 
    FIFRA specifically excludes as pests microorganisms in or on living man 
    or other living animals (as opposed to microorganisms on surfaces to 
    which man might be exposed). Effectiveness testing that would 
    demonstrate performance of an antimicrobial pesticide against 
    microorganisms in man and that would meet HHS' definition concerning 
    actual reduction or prevention of disease is not within EPA's purview.
        Based upon the laboratory tests that demonstrate efficacy for FIFRA 
    purposes, EPA permits label claims only to the extent that the product 
    reduces or eliminates target organisms under standard laboratory 
    conditions or carefully defined simulated use protocols. Because EPA 
    does not require or evaluate data on disease-related claims, 
    antimicrobial pesticide products are not permitted to bear claims 
    concerning reduction in transmission or prevention of disease, though 
    they may claim the ability to reduce precursor microorganisms.
        c. ``Sanitization'' claims. HHS requested clarification of the 
    scope of the Agency's policy on ``sanitary'' and ``sanitize'' as 
    pesticide public health claims. HHS noted that a product that 
    ``sanitizes'' food equipment would not be an ``antimicrobial 
    pesticide'' under FIFRA section 2(mm) because such use would be a food 
    use requiring a tolerance or exemption under section 408. They 
    requested clarificaiton as to whether such a sanitizer would be subject 
    to subpart W labeling requirements, and whether it would be a public 
    health pesticide.
    Response: Yes. A pesticide that sanitizes food equipment would be a 
    public health pesticide because sanitization is a claim of a specific 
    level of antimicrobial activity against microorganisms associated with 
    public health protection. It would therefore be subject to the labeling 
    requirements of proposed subpart W of part 156. As noted earlier, the 
    definition of ``antimicrobial pesticide'' in the proposal is broader 
    than that in the statute. EPA has revised Sec. 156.440 to clearly state 
    that the applicability of part 156, subpart W, corresponds to that in 
    part 152, subpart W, which would encompass food use sanitizers.

    XXI. Regulatory Assessment Requirements
    
    A. Executive Order 12866
    
        Under Executive Order 12866 (58 FR 51735, October 4, 1993), 
    entitled Regulatory Planning and Review, this action is not a 
    ``significant regulatory action'' subject to review by the Office of 
    Management and Budget (OMB). This proposal is not expected to have 
    significant impacts on antimicrobial pesticide producers and would have 
    no impacts on any other sector of the economy. Moreover, a number of 
    its provisions, including exemptions for various antimicrobial 
    sterilants, reduction in duplicative regulation with FDA, and mandatory 
    review periods for antimicrobial applications, are expected to decrease 
    costs and burdens currently associated with the registration of 
    antimicrobial pesticide products.
        EPA has prepared an economic analysis of the potential costs 
    associated with this proposed action, which is contained in a document 
    entitled Regulatory Impact Analysis of the Proposed Antimicrobial 
    Pesticide Rules. This document is available in the public record for 
    this action and is summarized in this unit.
        The only costs anticipated as a result of this action are the costs 
    of compliance with the ``sunset provision.'' Under this provision, 
    proposed in Sec. 152.458, registration of a public health antimicrobial 
    pesticide would expire every 5 years unless the registrant certifies, 
    based upon efficacy and composition studies conducted within the year 
    prior to expiration, that the product continues to meet the standards 
    for registration. The studies required are an analysis of the product 
    composition to confirm certified limits of the ingredients, and 
    efficacy studies for each public health claim on the product labeling.
        The costs of the analysis and certified limits determination are 
    estimated to be approximately $6,100 per product. The average cost of 
    the efficacy studies is estimated to be just under $25,500 per product, 
    based upon an average of six efficacy tests per product. The average 
    annualized testing cost per product is $5,620. However, while all 
    public health products would be subject to product analysis testing, 
    only about 61% of products would be subject to efficacy testing, 
    because some products can rely on testing developed for substantially 
    similar products. Accordingly the adjusted annualized testing cost for 
    products expected to actually have to conduct the testing is $3,897. 
    The total annualized cost for both existing and new products is 
    estimated to be $12.3 million.
        In neither case are these costs expected to result in additional 
    capital costs to applicants because such studies are currently required 
    of applicants for registration, whether conducted by the applicants 
    themselves, or, more typically, contracted for with outside 
    laboratories.
        The assumptions used in the analysis result in an overstatement of 
    the costs of the rule, for the following reasons:
        1. The analysis assumes that the testing requirement imposes costs 
    effective immediately upon promulgation in 1999. However, actual costs 
    will be imposed only as products are submitted for new or amended 
    registration or reregistration over the next several years, on a 
    schedule that EPA cannot predict. For a product first registered, 
    amended or reregistered in 1999, the testing cost would be imposed only 
    in the fourth year of registration (2003).
        2. The analysis assumed that no firms were already complying with 
    the sunset provisions that would be imposed. Based upon consultation 
    with a limited number of small businesses, EPA estimates that 
    approximately 11% of firms currently conduct testing that would comply 
    fully, and others conduct testing that would comply partially. It is 
    likely that a higher percentage of large firms would already be fully 
    or partially complying.
        All other provisions of this proposal would reduce the costs of 
    compliance with FIFRA for producers of antimicrobial pesticides. 
    Provisions that reduce costs include increased opportunities for 
    notification instead of amendment of registration, elimination of dual 
    jurisdiction with FDA, exemption of certain antimicrobial products from 
    FIFRA regulation, more precise and clearer application and labeling 
    information, and mandatory review periods for antimicrobial 
    applications that are shorter than historical review times.
    
    B. Regulatory Flexibility Act
    
        Under section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 
    601 et seq.), the Agency hereby certifies that this proposed action, if 
    promulgated as proposed, action will not have a significant economic 
    impact on a substantial number of small entities. The factual basis for 
    this determination is contained in the Economic Analysis referenced in 
    Unit XXI.A., and summarized in this unit. The only provisions in this 
    proposal that would impose costs on any business, including small 
    businesses, are the sunset provisions, discussed in Unit XXI.A.
        For the purpose of analyzing potential impacts on small entities, 
    EPA used the RFA definition of small entities in section 601(6) of the 
    RFA. Under this section, small entities include small governments, 
    small nonprofit organizations, and small businesses. Because EPA does 
    not believe that governments or nonprofit organizations are likely to 
    be burdened by this proposed rule, EPA's analysis presents only the 
    estimated potential impacts on small businesses.
        Table 7 below summarizes the results of EPA's analysis.

    2 Calculated on the basis of 848 small businesses registering antimicrobial products.
    3 The totals are cumulative, that is, the >3% and >10% values are included in the >1% totals.
    
        EPA believes that all costs and burdens of this proposed rule are 
    attributable to the ``sunset provision'' requiring periodic efficacy 
    retesting and analysis of products after registration. In preparing for 
    today's proposal, EPA conducted discussions with all segments of the 
    industry, including small business (see discussion in Unit XVIII.A.), 
    and we have adopted many of their suggestions to minimize burden. We 
    invite comment on whether there are additional accommodations specific 
    to the sunset provision that the Agency
    
    [[Page 50711]]
    
    should consider to further reduce the burden on small businesses.
        Based on consultation with the regulated community, EPA believes 
    that all other provisions would be both beneficial and cost-efficient 
    to all segments of the antimicrobial industry, including small 
    business. Specifically, EPA believes that there are overall reduced 
    paperwork burdens and costs associated with increased notifications and 
    exemptions from FIFRA; increased flexibility for applicants due to the 
    many opportunities for informal consultations, rebuttals, and 
    negotiations; greater clarity in the requirements for antimicrobial 
    registration and product labeling; and cost savings for individual 
    firms in obtaining registrations within the shortened review periods, 
    allowing earlier entry into the market. We invite comment on whether 
    there are additional accommodations we should consider that might 
    further facilitate the registration process for small businesses.
        Are there costs or burdens, efficiencies or savings attributable to 
    this proposed rule that you believe have not been adequately identified 
    and addressed? What are they and how great are these burdens or 
    efficiencies? If you have a proposal for additional accommmodations to 
    small business, please explain what you are proposing and provide 
    information on costs or benefits of your approach.
        For a discussion of the Agency's outreach to the antimicrobial 
    industry, including small businesses, and changes to this proposal 
    resulting from input by industry, including small businesses, refer to 
    Unit XVIII.A.
        Since the Agency's economic analysis for this proposal estimates 
    that 83% of all antimicrobial registrants are small businesses, EPA is 
    particularly interested in receiving comment from small businesses as 
    to the benefits, costs, and impacts of this proposed rule.
        Information relating to EPA's certification is provided upon 
    request to the Chief Counsel for Advocacy of the Small Business 
    Administration, and is included in the docket for this rulemaking. Any 
    comments regarding the economic impacts that this proposed regulatory 
    action may impose on small entities should be submitted to the Agency 
    at the address listed in ADDRESSES.
    
    C. Unfunded Mandates Reform Act
    
        Under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) 
    (Public Law 104-4), EPA has determined that this action does not 
    contain a Federal mandate that may result in expenditures of $100 
    million or more for State, local, and tribal governments, in the 
    aggregate, or the private sector in any 1 year. The costs associated 
    with this action are described in the Executive Order 12866 section 
    above. In addition, EPA has determined that the proposed rule will not 
    significantly or uniquely affect small governments and does not contain 
    a significant Federal intergovermental mandate. As such, this action is 
    not subject to sections 202, 203, 204 or 205 of UMRA.
    
    D. Consultation and Coordination with Indian Tribal Governments
    
        Under Executive Order 13084, entitled Consultation and Coordination 
    with Indian Tribal Governments (63 FR 27655, May 19, 1998), EPA may not 
    issue a regulation that is not required by statute, that significantly 
    or uniquely affects the communities of Indian tribal governments, and 
    that imposes substantial direct compliance costs on those communities, 
    unless the Federal government provides the funds necessary to pay the 
    direct compliance costs incurred by the tribal governments. If the 
    mandate is unfunded, EPA must provide to OMB, in a separately 
    identified section of the preamble to the rule, a description of the 
    extent of EPA's prior consultation with representatives of affected 
    tribal governments, a summary of the nature of their concerns, and a 
    statement supporting the need to issue the regulation. In addition, 
    Executive Order 13084 requires EPA to develop an effective process 
    permitting elected and other representatives of Indian tribal 
    governments ``to provide meaningful and timely input in the development 
    of regulatory policies on matters that significantly or uniquely affect 
    their communities.''
        Tribal governments would not be subject to the requirements of 
    today's proposal. In addition, for the most part, today's proposal 
    implements requirements specifically set forth by the Congress in FIFRA 
    without the exercise of any discretion by EPA. The remainder of today's 
    proposal does not significantly or uniquely affect the communities of 
    Indian tribal governments. Accordingly, the requirements of section 
    3(b) of Executive Order 13084 do not apply to this proposal.
    
    E. Enhancing Intergovernmental Partnerships
    
        Under Executive Order 12875, entitled Enhancing the 
    Intergovernmental Partnership (58 FR 58093, October 28, 1993), EPA may 
    not issue a regulation that is not required by statute and that creates 
    a mandate upon a State, local or tribal government, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by those governments. If the mandate is unfunded, EPA 
    must provide to OMB a description of the extent of EPA's prior 
    consultation with representatives of affected State, local and tribal 
    governments, the nature of their concerns, copies of any written 
    communications from the governments, and a statement supporting the 
    need to issue the regulation. In addition, Executive Order 12875 
    requires EPA to develop an effective process permitting elected 
    officials and other representatives of State, local and tribal 
    governments ``to provide meaningful and timely input in the development 
    of regulatory proposals containing significant unfunded mandates.''
        For the most part, today's proposal implements requirements 
    specifically set forth by the Congress in FIFRA without the exercise of 
    any discretion by EPA. The remainder of today's proposal would not 
    impose any enforceable duties on State, local or tribal governments. 
    Accordingly, the requirements of section 1(a) of Executive Order 12875 
    do not apply to this proposal.
    
    F. Federalism Review
    
        The Agency has determined that this action will not have a 
    substantial direct effect on States, the relationship between the 
    Federal government and States, the distribution in power between the 
    Federal government and States, the responsibilities among the levels of 
    government, or involve the potential pre-emption of State law as 
    described by Executive Order 12612, entitled Federalism (52 FR 41685, 
    October 30, 1987).
    
    G. Children's Health Protection
    
        This proposed rule is not subject to Executive Order 13045, 
    entitled Protection of Children from Environmental Health Risks and 
    Safety Risks (62 FR 19885, April 23, 1997) because this action is not 
    an economically significant regulatory action as defined by Executive 
    Order 12866 (see section A. of this unit). This proposed rule is 
    procedural in nature and does not involve decisions on environmental 
    health risks or safety risks that may disproportionately affect 
    children.
    
    [[Page 50712]]
    
    H. National Technology Transfer and Advancement Act
    
        Section 12(d) of the National Technology Transfer and Advancement 
    Act of 1995 (NTTAA), 15 U.S.C. 272 note) directs EPA to use voluntary 
    consensus standards in its regulatory activities unless to do so would 
    be inconsistent with applicable law or impractical. Voluntary consensus 
    standards are technical standards (e.g., materials specifications, test 
    methods, sampling procedures, etc.) that are developed or adopted by 
    voluntary consensus standards bodies. This proposed regulation does not 
    involve technical standards that would require Agency consideration of 
    voluntary consensus standards. EPA requests comment on this conclusion.
    
    I. Environmental Justice
    
        This proposed rule does not directly affect minority populations or 
    low-income groups. Therefore, under Executive Order 12898, entitled 
    Federal Actions to Address Environmental Justice in Minority 
    Populations and Low-Income Populations (59 FR 7629, February 16, 1994), 
    the Agency has not considered environmental justice-related issues with 
    regard to the potential impacts of this action on the environmental and 
    health conditions in low-income and minority communities.
    
    J. Paperwork Reduction Act
    
        The information collection requirements contained in this proposed 
    rule have been submitted to OMB under the Paperwork Reduction Act 
    (PRA), 44 U.S.C. 3501 et seq., and in accordance with the procedures at 
    5 CFR 1320.11. An Information Collection Request (ICR) document has 
    been prepared by EPA (EPA ICR No. 277.12) and a copy may be obtained 
    from Sandy Farmer, OP Regulatory Information Division; Environmental 
    Protection Agency (2137); 401 M St., SW.; Washington, DC 20460, by 
    calling (202) 260-2740, or electronically by sending an e-mail message 
    to: farmer.sandy@epa.gov. An electronic copy has also been posted with 
    the Federal Register notice on EPA's homepage with other information 
    related to this action and included in the public version of the 
    official record for the proposed rule. An Agency may not conduct or 
    sponsor, and a person is not required to respond to a collection of 
    information subject to OMB approval under the PRA unless it displays a 
    currently valid OMB control number. The OMB control numbers for EPA's 
    regulations, after initial publication in the Federal Register, are 
    maintained in a list at 40 CFR part 9.
        The annual public burden for this collection of information, which 
    will be submitted for approval as an addendum to the existing ICR 
    approved under OMB Control No. 2070-0060, is estimated to range from 1 
    hour to 10.4 hours per response, depending upon the activity. The cost 
    is estimated to range from $71.00 to $755.00 per response, again 
    depending on the particular response. The actual number of respondents 
    and the frequency of response are not known because many of the 
    responses are at the discretion of the respondent. However, based upon 
    EPA estimates, the revisions in the proposed rule would increase the 
    current burden by an estimated 6,395 hours and $466,740.
        Under the PRA, ``burden'' means the total time, effort, or 
    financial resources expended by persons to generate, maintain, retain, 
    or disclose or provide information to or for a Federal agency. For this 
    collection it includes the time needed to review instructions; 
    processing and maintaining information, and disclosing and providing 
    information; search data sources; complete and review the collection of 
    information; and transmit or otherwise disclose the information.
        Comments are requested on the Agency's need for this information, 
    the accuracy of the provided burden estimates, and any suggested 
    methods for minimizing respondent burden, including through the use of 
    automated collection techniques. Send comments on the ICR to the EPA at 
    the address provided above, with a copy to the Office of Information 
    and Regulatory Affairs, Office of Management and Budget, 725 17th St., 
    NW., Washington, DC 20503, marked ``Attention: Desk Officer for EPA.'' 
    Please remember to include the ICR number in any correspondence. The 
    final rule will respond to any comments on the information collection 
    requirements contained in this proposal.

        Therefore, it is proposed that 40 CFR chapter I, subchapter E be 
    amended as follows:
    
    PART 152--[AMENDED]
    
        1. In part 152:
        a. The authority citation for part 152 continues to read as 
    follows:
    
        Authority: 7 U.S.C. 136-136y.
    
        b. Section 152.1 is revised to read as follows:
    
    
    Sec. 152.1   Scope.
    
        Part 152 sets out procedures, requirements, and criteria for the 
    registration of pesticide products under FIFRA section 3, and for 
    associated regulatory activities affecting registration.
        (a) Subparts A, B, C, E, F, G, I, and U of this part apply to all 
    products except antimicrobial products.
        (b) Subparts A, B, E, F, G, I, U, and W of this part apply to 
    antimicrobial products.
        c. Section 152.3 is amended by removing the paragraph designations 
    for the existing definitions, removing the definition for 
    ``pesticide,'' revising the definitions for ``active ingredient''and 
    ``applicant'', and adding alphabetically new definitions to read as 
    follows:
    
    
    Sec. 152.3   Definitions.
    
          *    *    *    *    *
        Active ingredient means any substance (or group of structurally 
    similar substances if specified by the Agency) in a pesticide product 
    that will prevent, destroy, repel, or mitigate any pest, or that 
    functions as a plant regulator, desiccant, defoliant, or nitrogen 
    stabilizer.
          *    *    *    *    *
        Antimicrobial pesticide means a pesticide product that:
        (1) Is intended to have pesticide activity against microbiological 
    pests, or to protect inanimate articles, substances, industrial 
    processes or systems from deterioration, fouling, or contamination 
    caused by bacterial, viral, fungal, protozoan, algal or slime pests; 
    and
        (2) In the intended use is exempt from or not subject to the 
    requirement for a tolerance under FFDCA section 408 or a food additive 
    regulation under FFDCA section 409.
        (3) The term does not include any of the following:
        (i) A wood preservative or antifouling paint that makes any non-
    antimicrobial pesticidal claim (such as insecticidal), regardless of 
    whether it also makes an antimicrobial claim. A wood preservative that 
    makes only an antimicrobial claim is an antimicrobial pesticide.
        (ii) A fungicide for agricultural use. A fungicide is considered to 
    be for agricultural use if it is intended to be applied to soil or to 
    growing plants before harvest. A fungicide intended for post-harvest 
    use is not considered to be
    
    [[Page 50713]]
    
    for agricultural use. ``Fungus,'' as defined in FIFRA, includes rust, 
    smut, mildew, mold, yeast, and bacteria.
        (iii) A herbicide for aquatic use. A herbicide is considered to be 
    for aquatic use if it is intended to be applied directly to natural or 
    environmental bodies of water (such as lakes, ponds, or streams) or to 
    terrestrial areas bordering environmental bodies of water for control 
    of algae or weeds. A pesticide solely for control of algae in non-
    environmental waters (such as swimming pools or industrial water 
    systems) is considered to be an antimicrobial pesticide and not an 
    aquatic herbicide.
          *    *    *    *    *
        Applicant means a person applying for a new registration, or a 
    registrant applying for an amended registration or submitting a 
    notification.
        Application for registration means an application for new or 
    amended registration.
          *    *    *    *    *
        Complete application means an application for registration that 
    contains all data, forms, and information required by EPA to be 
    submitted with the application, and that will allow EPA to initiate 
    review, notwithstanding that EPA may determine that additional 
    information is required to approve the application. To be a complete 
    application, each required item, and the application as a whole, must 
    be determined by EPA to be complete, accurate, readable, and submitted 
    in the format and number of copies required by the Agency.
          *    *    *    *    *
        Fast-track application means an application under FIFRA section 
    3(c)(3).
        FFDCA means the Federal Food, Drug, and Cosmetic Act, as amended 
    (21 U.S.C 201 et seq.).
          *    *    *    *    *
        Nitrogen stabilizer means any substance or mixture of substances 
    intended for preventing or hindering the process of nitrification, 
    denitrification, ammonia volatilization or urease production through 
    action upon soil bacteria, except that the term does not include:
        (1) Dicyandiamide and ammonium thiosulfate; or
        (2) Any substance or mixture of substances in commercial agronomic 
    use before January 1, 1992, that was not registered before January 1, 
    1992, and for which the seller or distributor has made no specific 
    claims of preventing or hindering the process of nitrification, 
    denitrification, ammonium volatilization or urease production after 
    January 1, 1992.
        Registrant means a person to whom a registration has been issued. 
    In this part 152, if the term ``applicant'' and ``registrant'' would 
    both apply, the term ``applicant'' is used.
          *    *    *    *    *
        d. By adding new Sec. 152.6 to read as follows:
    
    
    Sec. 152.6   Substances excluded from regulation by FIFRA.
    
        Products and substances listed in this section are excluded from 
    FIFRA regulation if they meet the specified conditions or criteria.
        (a) Liquid chemical sterilants. A liquid chemical sterilant product 
    is not a pesticide under FIFRA section 2(u) if it meets all of the 
    following criteria. Excluded products are regulated by the Food and 
    Drug Administration. Products excluded are those meeting all of the 
    following criteria:
        (1) Composition. The product must be in liquid form as sold or 
    distributed. Pressurized gases or products in dry or semi-solid form 
    are not excluded by this provision. Ethylene oxide products are not 
    liquid products and are not exempt under this exclusion.
        (2) Claims. The product must bear a sterilant claim, or a sterilant 
    plus subordinate level disinfection claim. Products that bear 
    antimicrobial claims solely at a level less than ``sterilant'' are not 
    excluded and are jointly regulated by EPA and FDA. ``Sterilant'' is 
    defined in Sec. 156.441 of this chapter.
        (3) Use site. The product must be intended and labeled only for use 
    on ``critical or semi-critical devices.'' A ``critical device'' is any 
    device which is introduced directly into the human body, either into or 
    in contact with the bloodstream or normally sterile areas of the body. 
    A ``semi-critical device'' is any device which contacts intact mucous 
    membranes but which does not ordinarily penetrate the blood barrier or 
    otherwise enter normally sterile areas of the body. Liquid chemical 
    sterilants that bear claims solely for non-critical medical devices are 
    jointly regulated by EPA and FDA. Liquid chemical sterilants bearing 
    claims solely for use sites that are not medical devices, such as 
    veterinary equipment, are not excluded and are regulated by EPA.
        (b) Nitrogen stabilizers. A nitrogen stabilizer is excluded from 
    regulation under FIFRA if it is a substance (or mixture of substances) 
    meeting all of the following criteria:
        (1) The substance prevents or hinders the process of nitrification, 
    denitrification, ammonia volatilization, or urease production through 
    action affecting soil bacteria and is distributed and sold solely for 
    those purposes and no other pesticidal purposes.
        (2) The substance was in ``commercial agronomic use'' in the United 
    States before January 1, 1992. EPA considers a substance to be in 
    commercial agronomic use if it is available for sale or distribution to 
    users for direct agronomic benefit, as opposed to limited research, 
    experimental, or demonstration use.
        (3) The substance was not registered under FIFRA before January 1, 
    1992.
        (4) Since January 1, 1992, the distributor or seller has made no 
    claim that the product prevents or hinders the process of 
    nitrification, denitrification, ammonia volatilization, or urease 
    production. EPA considers any of the following claims (or their 
    equivalents) to be a claim that the product prevents or hinders 
    nitrification, denitrification, ammonia volatilization, or urease 
    production:
        (i) Improves crop utilization of applied nitrogen.
        (ii) Reduces leaching of applied nitrogen or reduces ground water 
    nitrogen contamination.
        (iii) Prevents nitrogen loss.
        (iv) Prolongs availability of nitrogen.
        (v) Increases nitrogen uptake, availability, usage, or efficiency.
        (5) A product will be consider to have met the criterion of 
    paragraph (b)(4) of this section that no nitrogen stabilization claim 
    has been made if:
        (i) The nitrogen stabilization claim, in whatever terms expressed, 
    is made solely in compliance with a State requirement to include the 
    claim in materials required to be submitted to a State legislative or 
    regulatory authority, or in the labeling or other literature 
    accompanying the product; and
        (ii) The State requirement to include the claim was in effect both 
    before the product bearing the claim was introduced into commercial 
    agronomic use, and before the effective date of this rule.
        (6) A product that meets all of the criteria of this paragraph with 
    respect to one State is not thereby excluded from FIFRA regulation if 
    distributed and sold in another State whose nitrogen stabilization 
    statement requirement does not meet the requirements of paragraph 
    (b)(5)(ii) of this section.
        (c) Human drugs. Human drugs for use in or on living man are not 
    for use against ``pests'' as defined in FIFRA section 2(t). Human drugs 
    are subject to regulation by the Food and Drug Administration under the 
    FFDCA.
        (d) Animal drugs. Viruses, bacteria or other microorganisms on or 
    in living animals are not ``pests'' under FIFRA section 2(t). A ``new 
    animal drug'' as
    
    [[Page 50714]]
    
    defined in section 201(w) of the FFDCA, or an animal drug that FDA has 
    determined is not a ``new animal drug'' is not a pesticide under FIFRA 
    section 2(u). Animal drugs are subject to regulation by the Food and 
    Drug Administration under the FFDCA.
        (e) Animal feeds. An animal feed containing a new animal drug is 
    not a pesticide under FIFRA section 2(u). Animal feeds containg new 
    animal drugs are subject to regulation by the Food and Drug 
    Administration under the FFDCA.
        (f) Vitamin hormone products. A product consisting of a mixture of 
    plant hormones, plant nutrients, inoculants, or soil amendments is not 
    a ``plant regulator'' under FIFRA section 2(v), provided it meets the 
    following criteria:
        (1) The product, in the undiluted package concentration at which it 
    is distributed or sold, meets the criteria of Sec. 156.62 of this 
    chapter for Toxicity Category III or IV; and
        (2) The product is not intended for use on food crop sites, and is 
    labeled accordingly.
    
    Sec. 152.8 [Amended]
    
        e. In Sec. 152.8, by removing paragraphs (a), (b), (c), 
    introductory text, (c)(2), (c)(3), and (c)(4), and redesignating 
    paragraph (c)(1) as paragraph (a) and redesignating paragraph (d) as 
    paragraph (b).
        f. In Sec. 152.20, by revising paragraph (b) to read as follows:
    
    
    Sec. 152.20   Exemptions for pesticides regulated by another Federal 
    agency.
    
          *    *    *    *    *
        (b) Non-liquid chemical sterilants. A non-liquid chemical 
    sterilant, except ethylene oxide, that meets the criteria of 
    Sec. 152.6(a)(2) with respect to its claims and Sec. 152.6(a)(3) with 
    respect to its use sites is exempted from regulation under FIFRA.
    
    Sec. 152.25 [Amended]
    
        g. Section 152.25 is amended by removing paragraph (d) and 
    redesignating (e) through (g) as paragraphs (d) through (f).
        h. Section 152.44 is amended by removing paragraph (b)(3), 
    redesignating paragraph (b)(4) as paragraph (b)(3), and adding new 
    paragraph (c) to read as follows:
    
    
    Sec. 152.44   Application for amended registration.
    
          *    *    *    *    *
        (c) A registrant may at any time submit identical minor labeling 
    amendments affecting a number of products as a single application if no 
    data are required for EPA to approve the amendment (for example, a 
    change in the wording of a storage statement for designated residential 
    use products). A consolidated application must clearly identify the 
    labeling modification(s) to be made (which must be identical for all 
    products included in the application), list the registration number of 
    each product for which the modification is requested, and provide 
    required supporting materials (for example, labeling) for each affected 
    product.

    Subpart W--Registration of Antimicrobial Products
    
    
    Sec. 152.440   General.
    
        (a) FIFRA section 3(h) requires EPA to establish by regulation 
    procedures for the registration of certain antimicrobial pesticide 
    products.
        (b) In order to register, and lawfully distribute or sell, an 
    antimicrobial product, a wood preservative or an antifouling paint 
    covered by FIFRA section 3(h), an applicant must comply with each of 
    the following:
        (1) This subpart, which describes the requirements, procedures, 
    conditions, and Agency review of applications for registration of 
    antimicrobial products. This subpart W substitutes for subpart C of 
    this part, which applies to all other products.
        (2) Subparts A, B, E, F, G, I, and U of this part. If any provision 
    of subpart W conflicts with any provision of these subparts, subpart W 
    applies instead.
        (3) Part 158 of this chapter, which describes the data requirements 
    for registration of antimicrobial products, wood preservatives, and 
    antifouling paints.
        (4) Part 156 of this chapter, which describes the labeling 
    requirements applicable to all products. Subpart W of part 156 of this 
    chapter specifies efficacy performance standards and acceptable 
    labeling claims for antimicrobial products bearing public health 
    claims.
        (5) Part 157 of this chapter, which establishes the criteria and 
    requirements for the use of child-resistant packaging.
    
    
    Sec. 152.441   Applicability.
    
        (a) This subpart applies to an application for registration of a 
    pesticide product that is any of the following:
        (1) An antimicrobial pesticide, as defined by FIFRA section 2(mm) 
    and Sec. 152.3, including a wood preservative or antifouling paint 
    product that makes only claims of antimicrobial pesticidal activity. 
    All sections of this subpart apply to such products.
        (2) Any product for which an antimicrobial claim is made, and which 
    is used in such a manner that a new or modified clearance is required 
    under FFDCA section 408 or 409. All sections of this subpart apply to 
    such products, except Sec. 152.457.
        (b) This subpart does not apply to an application for registration 
    of a pesticide product that is any of the following:
        (1) A wood preservative that makes any non-antimicrobial pesticidal 
    claim (for example, an insecticidal or fungicidal claim), regardless of 
    whether an antimicrobial claim is also made for the product.
        (2) An antifoulant product that makes any non-antimicrobial 
    pesticidal claim, regardless of whether an antimicrobial claim is also 
    made for the product.
    
    
    Sec. 152.442   Definitions.
    
        Terms used in this subpart have the same definitions as in the Act 
    and subpart A of this part. For the purposes of this subpart, the 
    following terms are defined:
        Clearance means any of the following:
        (1) A tolerance under FFDCA section 408(b).
        (2) An exemption from the requirement of a tolerance under FFDCA 
    section 408(c).
        (3) A food additive regulation under FFDCA section 409.
        (4) An approval of a medical device under FFDCA section 510(k).
        Complete application means an application for registration that 
    contains all data, forms, and information required by EPA to be 
    submitted with the application, and that will allow EPA to initiate 
    review, notwithstanding that EPA may determine that additional 
    information is required to approve the application. To be a complete 
    application, each required item, and the application as a whole, must 
    be determined by EPA to be complete, accurate, readable, and submitted 
    in the format and number of copies required by the Agency.
    
    [[Page 50715]]
    
        Major new use means a new antimicrobial use of a registered active 
    ingredient, as used in FIFRA section 3(h).
        Minor amendment means an amendment to an antimicrobial registration 
    that does not require the review of scientific data.
        Substantive amendment means an amendment to an antimicrobial 
    registration that requires scientific review of data.
    
    
    Sec. 152.443   Who may apply.
    
        (a) New registration. Any person may apply for new registration of 
    an antimicrobial product. A person seeking a new registration for an 
    antimicrobial product must submit an application for registration 
    containing the information specified in Sec. 152.450. An application 
    for new registration must be approved by the Agency before the product 
    may lawfully be distributed or sold, except as provided by Sec. 152.30.
        (b) Amended registration. (1) Any registrant may apply for 
    amendment of his/her registration to modify the composition, labeling, 
    or packaging of the product. Except as provided by Sec. 152.446, a 
    registrant may modify the registration only by submitting an 
    application for amended registration. The applicant must submit the 
    information specified in Sec. 152.450, as applicable to the change 
    requested.
        (2) Except as provided by paragraph (c) of this section, the 
    registrant must submit a separate application for each amendment.
        (3) If an application for amendment is required, the application 
    must be approved by the Agency before the product, as modified, may 
    lawfully be distributed or sold.
        (c) Consolidation of amendments. A registrant may at any time 
    submit identical minor labeling amendments affecting a number of 
    products as a single application if no data are required for EPA to 
    approve the amendment (for example, a change in the wording of a 
    storage statement for designated household products). A consolidated 
    application must clearly identify the labeling modification(s) to be 
    made (which must be identical for all products), list the registration 
    number of each product for which the modification is requested, and 
    provide required supporting materials (for example, labeling) for each 
    affected product.
        (d) Alternatives to amendment. In its discretion, the Agency may:
        (1) Waive the requirement for submission of an application for 
    amended registration.
        (2) Permit an applicant to modify a registration by notification or 
    non-notification in accordance with Sec. 152.446.
        (e) Certification statement. In its discretion, the Agency may 
    permit an applicant to certify to the Agency that the applicant has 
    complied with an Agency directive or requirement with respect to any 
    element of a new or amended registration. If the Agency determines that 
    a requirement may be satisfied by an applicant certification, the 
    Agency will provide, through a guidance document available to the 
    general public, detailed instructions on a certification process. The 
    guidance document will specify the content of a certification 
    statement, any materials that must be submitted with the certification 
    or maintained by the applicant, and the manner of submission of the 
    certification.
    
    
    Sec. 152.444   Alternate formulations.
    
        (a) A product proposed for registration must have a single, defined 
    composition of active and inert ingredients, except that EPA may 
    approve a basic formulation and one or more alternate formulations 
    under a single registration.
        (b) An alternate formulation must meet the criteria listed in 
    paragraph (b)(1) through (b)(4) of this section. The Agency may require 
    the submission of data to determine whether the criteria have been met.
        (1) The alternate formulation must contain, and have the same 
    certified limits for, each active ingredient in the basic formulation.
        (2) If the alternate formulation contains an inert ingredient or 
    impurity of toxicological significance, the formulation must have the 
    same upper certified limit for that substance as the basic formulation.
        (3) The label text of the alternate formulation product must be 
    identical to that of the basic formulation.
        (4) The analytical methods required under Sec. 158.180 of this 
    chapter must be suitable for use on both the basic formulation and the 
    alternate formulation.
        (c) Notwithstanding the criteria in this section, the Agency may 
    determine that an alternate formulation must be separately registered. 
    If EPA makes this determination, the Agency will notify the applicant 
    of its determination and its reasons. Thereafter the application for an 
    alternate formulation will be treated as an application for new 
    registration.
    
    
    Sec. 152.445   Types of antimicrobial applications.
    
        The following types of applications are identified solely for 
    purposes of this subpart, in order to establish review periods. 
    Identification of application types in this section does not modify 
    similar terms used elsewhere in EPA regulations. Application categories 
    generally differ based upon factors related to the active ingredient 
    status, the product formulation type, the uses proposed, and whether 
    data are required with the application. An application may fall into 
    only one category, as determined by EPA.
        (a) Application for registration of a food or feed use. (1) Any 
    application for registration that proposes a use that would require the 
    establishment of a new or modified clearance under the FFDCA. Under the 
    FFDCA, a clearance must be granted, either by EPA or by FDA, for uses 
    that might result, directly or indirectly, in residues in raw or 
    processed food or animal feed.
        (2) The review periods in Sec. 152.457 do not apply to applications 
    covered by paragraph (a)(1) of this section. Such applications require 
    significantly more data, require a longer review time, and are subject 
    to formal approval by regulation under the FFDCA.
        (b) Application for new registration--(1) New active ingredient. An 
    application for registration of a new product containing any active 
    ingredient that is not contained in a currently registered product.
        (2) Substantially similar product. An application for new 
    registration of a product that meets all of the criteria in this 
    paragraph.
        (i) Formulation. The product formulation contains the same active 
    ingredients and is substantially similar in composition to a cited 
    currently registered product.
        (ii) Uses. The proposed uses are substantially similar to the uses 
    on the label of the cited product. The proposed product may bear fewer 
    uses than the cited product, but may not bear expanded uses or 
    different uses or claims.
        (iii) Method of data support. The application relies solely upon 
    data from a substantially similar registration for support (with the 
    exception of certain product chemistry data, which must be submitted 
    for all new products) and does not require the submission of efficacy 
    data.
        (3) Identical product. An application for registration of a product 
    that meets both of the criteria in this paragraph.
        (i) Formulation. The formulation (including inert ingredients) is 
    identical in composition to a cited currently registered formulation. 
    Typically such a product either is a currently registered formulation 
    that is being repackaged as a new product without separate
    
    [[Page 50716]]
    
    production, or is a formulation of identical composition to another 
    product that is being separately produced according to specifications 
    provided by the registrant of the cited product.
        (ii) Uses and claims. The proposed uses are identical to those on 
    the cited product, with no deviation in use sites or directions for 
    use. A product may have fewer uses than on the cited product, but not 
    different or expanded uses or claims.
        (4) New product with major new use. An application for new 
    registration that also proposes a ``major new use,'' as described in 
    paragraph (c)(1) of this section. Any application for a new 
    registration that proposes only an additional or different use that is 
    not a major new use will be considered to be a new registration 
    described in paragraph (b)(5) of this section.
        (5) Other new product. Any application for new registration that 
    does not meet the criteria of paragraph (b)(1) through (b)(4) of this 
    section. These products usually require the submission of data. 
    Examples of what would be included in this category are applications 
    for registration of a product of any of the types listed below.
        (i) The product is a formulation of different active ingredients 
    than is contained in any currently registered product.
        (ii) The product contains the same active ingredients, but is in a 
    different physical form (liquid, powder) than any other registered 
    product containing the same active ingredients, or is not substantially 
    similar in composition to a cited currently registered product.
        (iii) The product has any unregistered source of any active 
    ingredient, regardless of the fact that the active ingredient is 
    currently registered in another product. Use of an unregistered source 
    of active ingredient requires review of supporting data for the 
    unregistered ingredient.
        (iv) The product has an additional use that is not currently 
    registered for any substantially similar product.
        (v) The product requires the submission of efficacy data because 
    the formulation is not identical to another product.
        (c) Amendments to registration--(1) Major new use. An application 
    for amended registration to add a major new use that is not currently 
    registered for one or more of the active ingredients in the product. 
    The major new use would generally be significantly different in the 
    manner of use and exposure to humans or the environment from other 
    registered use patterns for the active ingredient.
        (2) Substantive amendment. An amendment that is not a major new 
    use, and that requires scientific review of data. These include, but 
    are not limited to, the following types of amendments:
        (i) Any amendment that contains a data submission.
        (ii) The addition of a use that has been approved for another 
    registered product containing the same active ingredients, but which is 
    not a substantially similar product as the registration for which the 
    amendment is sought.
        (iii) Except as permitted by Sec. 152.446, Notifications and non-
    notifications, a change in precautionary or other hazard statements, 
    use instructions, minor changes in ingredients that do not modify label 
    statements, change in use concentrations, method of application, or 
    pests.
        (3) Minor amendment. An amendment to an existing registration which 
    does not require scientific review of any type. In no case does an 
    application for a minor amendment contain data for review. A minor 
    amendment might include, but is not limited to, changes for which EPA 
    must:
        (i) Examine briefly or determine the applicability of previously 
    submitted data (without scientific evaluation of such data).
        (ii) Compare composition, characteristics or labeling with other 
    products.
        (iii) Evaluate the adequacy of the applicant's data citations or 
    method of support.
        (iv) Determine whether an adequate basis exists for a proposed 
    label statement.
        (v) Determine whether a proposed use is substantially similar to an 
    approved use for a cited substantially similar product.
    
    
    Sec. 152.446   Notifications and non-notifications.
    
        (a) Changes permitted by notification--(1) Notifications permitted 
    by statute. A registrant of an antimicrobial product may add relevant 
    information on product efficacy, product composition, container 
    composition or design, or other characteristics that do not relate to 
    pesticidal claims or activity. An example of a product efficacy claim 
    that does not relate to pesticidal claims or activity would be a 
    cleaning, deodorizing, or polishing claim.
        (2) Notifications permitted by EPA. In addition, EPA may determine 
    that certain minor modifications to registration having no potential to 
    cause unreasonable adverse effects to the environment may be 
    accomplished by notification to the Agency, without requiring the 
    registrant to obtain Agency approval. If EPA so determines, it will 
    issue a notice to registrants describing the types of modifications 
    permitted by notification.
        (b) Procedure for notification. All notifications must be submitted 
    in accordance with the procedures of this paragraph and any 
    supplemental notice to registrants.
        (1) Submission. A registrant must submit the notification to the 
    Agency at least 60 days before distribution or sale of a product as 
    modified.
        (2) Substantiation. The registrant must retain, and submit to the 
    Agency upon request, substantiating information or data supporting the 
    proposed modification. These data need not be submitted with the 
    notification unless specified in a notice issued in accordance with 
    paragraph (a)(2) of this section. The substantiating information may be 
    required, however, in accordance with paragraph (b)(4) of this section 
    if the notification is disapproved.
        (3) Agency decision. Within 30 days after receipt, the Agency will 
    notify the registrant in writing if the notification is disapproved and 
    state the reasons why it is unacceptable.
        (4) Objection. A registrant may file an objection to a disapproval 
    in writing not later than 30 days after receipt of the Agency's 
    disapproval. If the basis for the disapproval is that substantiating 
    information is needed, the registrant must submit such information as 
    part of the objection. A decision by EPA after receipt and 
    consideration of an objection is a final agency action.
        (5) Distribution or sale. A registrant may not distribute or sell a 
    product for which a modification by notification is proposed until the 
    registrant receives EPA notice of approval, or until 60 days after 
    submission of the notification, whichever comes first. A registrant may 
    not sell or distribute a product bearing a disapproved modification.
        (c) Changes permitted without notification. EPA may determine that 
    certain minor changes to registration having no potential to cause 
    unreasonable adverse effects to the environment may be accomplished 
    without notification to or approval by the Agency. If EPA so 
    determines, it will issue a notice to registrants describing the types 
    of changes permitted without notification (known as non-notifications). 
    A registrant may distribute or sell a product changed as permitted by 
    such notice without notification to or approval by the Agency.
        (d) Effect of non-compliance. Notwithstanding any other provision 
    of
    
    [[Page 50717]]
    
    this section, if the Agency determines that a product has been modified 
    through notification or without notification in a manner inconsistent 
    with paragraphs (a) through (c) of this section or any notice issued 
    thereunder, EPA may initiate regulatory or enforcement action, or both, 
    without first providing the registrant with an opportunity to submit an 
    application for amended registration.
    
    
    Sec. 152.447   Consultation with EPA.
    
        (a) Optional consultation. An applicant may consult the Agency at 
    any time prior to submitting an application. Consultations should be by 
    the most efficient and least time-consuming method available that 
    satisfies the applicant's need. For minor questions or guidance, fax 
    and e-mail are preferred, so that the Agency may respond both rapidly 
    and in writing.
        (b) Meetings. If a meeting is desired, applicants should contact 
    the appropriate team leader or Branch Chief and provide a proposed 
    agenda, list of likely attendees, and requested date(s). If EPA agrees 
    that a meeting would be productive, EPA will schedule the meeting, 
    honoring the applicant's requested times insofar as practicable, and 
    will invite needed Agency personnel. EPA may choose not to meet with 
    applicants if matters can be resolved by other means.
        (c) Required consultation. An applicant must consult the Agency 
    before submitting an application for registration if:
        (1) The application is for a new chemical or major new use. It is 
    strongly recommended that this consultation be a meeting or conference 
    call with written confirmation of any agreements.
        (2) The applicant wishes to develop data using different or 
    modified protocols for required efficacy studies, or if no test method 
    is specified. In some cases, EPA approval of alternate protocols and 
    test standards is required. Consultation would typically consist of a 
    written explanation of the modifications proposed or the proposed 
    protocol, which EPA would approve in writing.
        (d) Written determinations. An applicant may rely upon regulatory 
    determinations only if in writing from EPA.
        (e) Reliance on EPA determinations. EPA will not change the 
    regulatory decisions contained in a written determination issued under 
    paragraph (d) of this section unless:
        (1) EPA concludes that its determination was in error.
        (2) The applicant modifies the circumstances upon which the 
    determination was based or EPA determines that the circumstances are 
    other than described by the applicant.
        (3) The applicant fails to submit the application in a timely 
    manner, such that EPA's determination no longer comports with Agency 
    regulations or policy; or
        (4) EPA has information that raises concerns that an unreasonable 
    adverse effect on the environment may result unless it changes its 
    determination.
    
    
    Sec. 152.450   Contents of application.
    
        Each application for registration must include the data, 
    information, and forms listed in this section.
        (a) Application for registration. The applicant must submit an 
    application form provided by the Agency. The application form is 
    required for all applications, both new and amended, as well as for 
    notifications under Sec. 152.446. To be complete:
        (1) The applicable parts of the form must be properly and 
    accurately filled in, according to the instructions provided with the 
    form.
        (2) The applicant must identify on the form which type of 
    application the applicant believes is being submitted for purposes of 
    review time computation. Types of applications are listed in 
    Sec. 152.445.
        (3) If the application relies on an ``identical'' or 
    ``substantially similar'' product, the applicant must provide the EPA 
    Registration Number of the product claimed as identical or 
    substantially similar.
        (4) The form must be signed by an authorized representative of the 
    applicant and must be dated.
        (b) Authorization for agent. The applicant must submit a letter of 
    authorization designating an agent residing in the United States if the 
    applicant is located outside of the United States or if the applicant 
    wishes to use an agent. To be complete, the authorization must:
        (1) Be on the applicant's company letterhead.
        (2) Provide identifying information for the agent, including name, 
    address, and telephone numbers (fax and e-mail are requested if 
    available).
        (3) Affirm that the person designated is authorized to serve as 
    agent with respect to specified applications or registrations and 
    provide a clear description of the products or applications covered and 
    any limitations on the authorization.
        (4) Be signed (with name and title) by an authorized representative 
    of the applicant and be dated.
        (c) Summary of application. An application for registration must 
    contain a publicly releasable summary of the application, including a 
    list of the data submitted or cited in support of the application, 
    together with a brief summary of the results of any studies submitted. 
    This summary may be combined with that required for any other purpose.
        (d) Statement of Formula. (1) The applicant must submit a Statement 
    of Formula that identifies the composition of the product proposed for 
    registration. A Statement of Formula is required for:
        (i) Each application for new registration.
        (ii) Each application for amended registration that proposes any 
    change in the product composition or a change in other information on 
    the previous Statement of Formula.
        (iii) Each notification under Sec. 152.446 which affects the 
    composition of the product.
        (2) To be complete, the Statement of Formula must be accurately 
    filled out with all required information, and must be signed by an 
    authorized representative of the applicant.
        (e) Labeling. (1) The applicant must submit the number of copies of 
    draft labeling specified by the Agency. Generally four copies of draft 
    labeling must be submitted. Draft labeling is required for:
        (i) Each application for new registration.
        (ii) Each application for amended registration, if the amendment 
    proposes a label change or a labeling change is otherwise necessitated 
    by the amendment (e.g., a change in composition affecting the 
    labeling).
        (iii) Each notification under Sec. 152.446 that modifies any 
    portion of the labeling.
        (2) To be complete, the labeling submission must:
        (i) Include both the product label and any supplemental labeling, 
    brochures, or other printed material that is intended to accompany the 
    product in distribution or sale.
        (ii) In the case of an amendment to existing labeling, be identical 
    in wording to the last approved labeling, except for proposed changes 
    (and any previously accepted notification), which must be marked.
        (iii) Be suitable for photocopying. In general, highlighting does 
    not photocopy; changes need to be marked or circled in black ink. 
    Product packaging bearing the labeling is not acceptable for this 
    purpose.
        (f) Method of support documentation. The applicant must submit 
    documentation of the method of support that will be used to satisfy 
    each data requirement that applies to the
    
    [[Page 50718]]
    
    application. Various forms provided by the Agency must be submitted to 
    document the applicant's choices. This paragraph summarizes data 
    support requirements. The applicant must comply with subpart E of this 
    part, which contains detailed requirements and exceptions to the data 
    support process.
        (1) In general, the following choices for each data requirement are 
    available:
        (i) The applicant may submit the data. In all cases, an applicant 
    may submit a study that satisfies a data requirement. Typically certain 
    data must be submitted (product chemistry) and may not be cited. Refer 
    to paragraph (g) of this section for information on data submission.
        (ii) The applicant may cite the data with permission or offer to 
    pay. If the data are exclusive use data, the applicant must have 
    written permission from the data submitter. If the data are subject to 
    compensation provisions, the applicant must have made appropriate 
    offers to pay to each data submitter(s). Refer to paragraph (f)(2) of 
    this section for the forms used to properly document citation of data.
        (iii) The applicant may request in writing a waiver of the data 
    requirement, together with a rationale for each waiver requested. A 
    waiver request without a rationale is not complete.
        (2) To be complete, the applicant who submits or cites data to 
    satisfy any data requirement must submit, as applicable, one or more of 
    the following:
        (i) A data reference sheet (data matrix). This is a listing of all 
    data requirements applicable to the product, identifying the means of 
    satisfying each requirement, and must be submitted whenever an 
    applicant submits his/her own data or uses the selective method of data 
    support (see Sec. 152.90). To be complete, each citation of data must 
    include the Master Record Identification number, if known, or contain 
    sufficient detail (title, date of submission, name and EPA identifying 
    number of product) that EPA may clearly identify the item of data in 
    its files.
        (ii) A formulator's exemption form. This form is used when the 
    applicant claims an exemption from certain data requirements because 
    the applicant produces his/her product using a purchased registered 
    source product. A single formulator's exemption form may be used for 
    all data requirements to which the exemption applies. The form must 
    identify the registration number of each source product.
        (iii) Certification with respect to citation of data. This form is 
    used to certify that the applicant has complied with all requirements 
    pertaining to data submission and citation. The form must be submitted 
    with each application for registration.
        (g) Data and information. (1) The applicant must satisfy data 
    requirements by submitting or properly citing data and information in 
    support of the application, unless the applicant obtains a waiver of 
    the data requirement, or unless EPA permits an alternate method of 
    satisfying data requirements (such as certification). Data requirements 
    are found in part 158 of this chapter.
        (2) To be complete, the data submission must meet the following 
    criteria:
        (i) Final report of study. The submission must contain a final 
    report of each study, including all information specified in Agency 
    guidance (e.g., identity of substance tested).
        (ii) Summary of results of data. The application must include a 
    publicly releasable summary of the results of each study submitted. The 
    results of all studies may be consolidated into a single summary.
        (iii) Format. Each study individually, and the data submission as a 
    whole, must conform to Agency requirements for formatting and 
    presentation, as specified in Sec. 158.32 of this chapter and Agency 
    guidance.
        (iv) Confidential business information (CBI). Each study must 
    conform to Agency requirements in Sec. 158.33 of this chapter with 
    respect to identification, marking, and presentation of CBI.
        (v) Certification of Good Laboratory Practice (GLP) compliance. 
    Each study must include a certification in accordance with Sec. 160.12 
    of this chapter.
        (vi) Identification of studies demonstrating potential adverse 
    effects. Each study that meets the criteria of Sec. 158.34 of this 
    chapter for potential adverse effects must be identified and the 
    certification statement required by that section must be included. The 
    studies to which this requirement applies are subchronic and chronic 
    toxicity studies.
        (h) Data or information pertaining to adverse effects. An applicant 
    must submit any factual information regarding unreasonable adverse 
    effects of this pesticide on man or the environment. The information 
    that must be submitted is that which would be required to be reported 
    under FIFRA section 6(a)(2) if the product were registered (see part 
    159 of this chapter). This requirement applies to each application for 
    new registration. The requirement does not apply to an application for 
    amended registration. To be complete, submission of adverse effects 
    information must be in accordance with part 159 of this chapter.
        (i) Food use clearance. If the application proposes a use of the 
    pesticide on food or feed crops, or if the intended use of the 
    pesticide results or may be expected to result, directly or indirectly, 
    in pesticide chemical residues in or on food or feed, the applicant 
    must submit one of the following:
        (1) A citation to each clearance that covers the proposed food or 
    feed use(s).
        (2) A petition under FFDCA section 408 requesting the establishment 
    of a food clearance for each ingredient for which there is no current 
    clearance. Requirements for pesticide petitions are contained in 40 CFR 
    part 180. If a petition is required, an application for registration is 
    not complete unless all requirements for the petition are satisfied.
        (3) Evidence of acceptance of a petition for a food additive 
    regulation by the FDA, if a food additive regulation is required. A 
    copy of the notice of filing of the petition in the Federal Register is 
    acceptable for this purpose.
        (j) Documentation of pre-submission consultation. If a pre-
    submission consultation is required by Sec. 152.447, the applicant must 
    submit written documentation that the consultation took place, and a 
    copy of any resulting regulatory decisions regarding the application or 
    its review (for example, agreement as to the type of application being 
    submitted, or specific data requirements imposed or waived).
        (k) Data reviews conducted by other regulatory authorities. The 
    applicant must state whether the data supporting the application have 
    been, or are being, reviewed by State, Federal, or other national 
    regulatory authorities. If so, the applicant must identify the 
    reviewing authority and purpose of the review and must submit any 
    available data reviews conducted by such regulatory authorities that 
    are in the applicant's possession. The applicant is not required to 
    obtain regulatory reviews for this purpose.
        (l) Other clearances. If the applicant is required to obtain 
    clearances or approvals from other Federal (not State) agencies before 
    a product may be distributed and sold, or used as proposed on the 
    label, the applicant must submit either:
        (1) A copy of each such clearance or approval if already obtained; 
    or
        (2) A copy of a request to the appropriate agency for each such 
    clearance or approval.
        (m) Packaging--(1) Child-resistant packaging (CRP). If the product 
    is
    
    [[Page 50719]]
    
    required by part 157 of this chapter to be distributed and sold only in 
    CRP, or if the product will be sold in CRP, the applicant must submit a 
    certification statement that the product meets the criteria for CRP in 
    Sec. 157.32 of this chapter.
        (2) In no case is actual product packaging to be submitted with an 
    application for registration. If EPA needs to evaluate the actual 
    product packaging, it will request submission.
        (n) Product samples. In no case is a sample of the product to be 
    submitted with an application. Product or ingredient samples may be 
    required by the Agency for various purposes, but will be requested 
    separately and must be submitted to the address in the request.
        (o) Self-addressed notice for completeness determination. (1) An 
    applicant may (but is not required to) provide a postcard (preferred) 
    or form letter that EPA may use for notification of receipt of an 
    application that EPA has preliminarily determined is complete.
        (2) A postcard or form letter for this purpose must be addressed to 
    the applicant at his/her address of record, stamped with sufficient 
    U.S. postage, and provide a means (checkoff, space, box) for EPA to 
    record the registration number or file symbol of the application, the 
    fact that the application is complete, the date of EPA receipt, and the 
    expected date for decision based upon the type of application.
        (3) If a means of notifying the applicant is not provided, EPA will 
    not otherwise notify an applicant in writing that the application is 
    complete. EPA may, but is not required to, telephone or e-mail an 
    applicant who does not provide written means of notification.
        (p) Fees. If fees are required to be submitted for any application, 
    or in conjunction with a petition for a clearance associated with an 
    application, such fees must be submitted in accordance with Agency 
    guidance. An application is not complete unless required fees have been 
    submitted.
        (q) Authorizations. (1) The applicant is requested, but not 
    required, to provide authorization for EPA to share studies submitted 
    by the applicant, or EPA's reviews of such studies, with other 
    regulatory authorities, including Federal, State, or national bodies 
    that may regulate pesticides. Such authorization would apply only to 
    the exchange of data or EPA reviews of data that might contain 
    Confidential Business Information (CBI) or information protected under 
    FIFRA section 10(g), unless the applicant provided a broader disclosure 
    authorization.
        (2) If the applicant chooses to authorize any degree of data/review 
    sharing, the applicant should include with his/her application, on 
    company letterhead and signed by an authorized representative of the 
    applicant, one of the following:
        (i) A blanket authorization for EPA to exchange data or EPA data 
    reviews pertaining to all of the applicant's products.
        (ii) A specific authorization for EPA to exchange data or EPA data 
    reviews pertaining to an ingredient(s) or product(s) designated in the 
    authorization.
        (iii) A specific authorization for EPA to exchange data or EPA data 
    reviews pertaining to data submitted with the application.
        (iv) Any other form of authorization, identifying the ingredients, 
    products or data to which the authorization pertains and limitations 
    upon the authorization.
        (3) If an applicant chooses not to authorize EPA data/review 
    sharing at the time of application, EPA may, in its discretion, 
    disclose data or reviews in those circumstances where no authorization 
    is needed, and seek consent for disclosure where needed on a case-by-
    case basis.
    
    
    Sec. 152.451   How to submit applications.
    
        (a) Applications must be submitted to the Agency by U.S. mail, 
    courier service, or in person. EPA provides in guidance documents or 
    upon request the appropriate address for each type of delivery. 
    Applications may not be submitted electronically or by fax.
        (b) EPA will not automatically provide evidence of receipt of an 
    application. An applicant who wishes confirmation of delivery to EPA 
    should use certified mail or courier services that provide 
    confirmation.
    
    
    Sec. 152.455   Action on applications.
    
        (a) Incomplete application. EPA will screen each application for 
    completeness, as specified in Sec. 152.450. If EPA determines that the 
    application is not complete, EPA will notify the applicant in writing 
    of the deficiency(ies) in the application. EPA will not place into 
    review, or compute review periods, for any application it finds 
    incomplete.
        (b) Preliminary determination of complete application. If EPA makes 
    a preliminary determination that the application is complete, it will 
    place the application into review. The appropriate review period in 
    Sec. 152.457 will be computed from the date of receipt by EPA of the 
    last item that completes the application.
        (c) EPA review of application. EPA will review each application for 
    which a preliminary determination of completeness has been made. EPA 
    will notify the applicant in writing of its decision on the application 
    upon completion of all required reviews. EPA may, in its discretion, 
    communicate with the applicant informally on the progress and interim 
    results of the review. Such informal communications do not constitute a 
    decision on the application, and do not affect the review period.
        (d) Decision on application. When all reviews are completed, EPA 
    will take one of the following actions on the application:
        (1) Approve the application. (i) EPA will approve an application 
    for registration if it meets the criteria of Sec. 152.112, 
    Sec. 152.113, or Sec. 152.114, as applicable.
        (ii) If EPA approves the application, EPA will issue a Notice of 
    Registration and provide the applicant a copy of the stamped approved 
    labeling, together with any labeling modifications that must be made. 
    Before distributing or selling the pesticide product, the applicant 
    must submit final printed labeling to the Agency, modified as specified 
    by EPA in approving the registration and in the number of copies 
    required by EPA. Thereafter, the registrant may distribute and sell the 
    product under the terms approved by EPA.
        (iii) If EPA approves the application for a product on terms that 
    differ from those requested by the applicant, the applicant may file a 
    written objection and request that EPA reconsider the terms that are 
    objectionable. An objection must be filed within 30 days of the date on 
    which EPA approved the application, and must set out in detail the 
    basis of the objection and the alternative terms of registration 
    requested. The applicant may not distribute or sell the product until 
    the objection is resolved. EPA will use its best efforts to respond 
    within 45 days of receipt of a timely, written objection.
        (2) Determine that the application remains incomplete. EPA may 
    determine that, notwithstanding its preliminary determination of 
    completeness, the application remains incomplete. If EPA so determines, 
    it will notify the applicant of the deficiencies in the application. 
    The applicant's resubmission will be treated in accordance with either 
    paragraph (d)(2)(i) or (d)(2)(ii) of this section.
        (i) Qualifying resubmission. EPA will treat a complete and timely 
    response
    
    [[Page 50720]]
    
    from the applicant as a ``qualifying resubmission'' subject to the 
    review period in Sec. 152.457(e), and will make a final decision on the 
    application without recomputing a full second review period provided by 
    Sec. 152.457(c) or (d), if:
        (A) The original application has a review period of 120 
    days;
        (B) EPA determines, in its sole discretion, that the deficiency is 
    less serious; and
        (C) The deficiency is corrected within 30 days of receipt of EPA's 
    notice to the applicant.
        (ii) Non-qualifying resubmission. EPA will recompute a second full 
    review period beginning on the date of receipt of the last item 
    completing the application, and will make a final decision on the 
    application within the review periods in Sec. 152.457(c) or (d), as 
    applicable, if:
        (A) The original application has a review period of >120 days;
        (B) EPA determines, in its sole discretion, that the deficiency is 
    serious; or
        (C) The applicant does not respond within 30 days.
        (3) Determine that the applicant has not supplied all data or 
    information required to determine the acceptability of the 
    registration. EPA may determine that, despite its preliminary 
    determination of completeness, the applicant has not supplied 
    sufficient information to issue a registration decision. If EPA so 
    determines, it will notify the applicant, identify the additional 
    information or data needed, and require that the applicant submit, by a 
    specified date, the information or data needed. As of the date of EPA's 
    notification to the applicant, the review period will stop. The elapsed 
    time between date of notification and receipt of response will not be 
    counted in computing the date for a decision under Sec. 152.457. Based 
    upon the nature of the deficiencies, the time anticipated for the 
    applicant to correct the deficiencies, and the additional time needed 
    by EPA to review the material submitted in response to the notice of 
    deficiency, EPA will specify in its notification one of two review 
    period decisions:
        (i) EPA may specify that the review period will resume as of the 
    date of receipt of the applicant's complete and timely response; or
        (ii) EPA may specify that the review period will resume after a 
    specified period following receipt of the applicant's complete and 
    timely response.
        (4) Deny the application for failure to submit required 
    information. If, after notification in accordance with paragraph (d)(3) 
    of this section, the applicant does not respond, or does not provide 
    all required data or information within the specified time, EPA may 
    deny the application in accordance with the procedures of Sec. 152.118. 
    These procedures provide that EPA will issue a Notice of Intent to Deny 
    (NOID) the application, stating the reasons and factual basis for 
    denial, and permit the applicant 30 days to take corrective action. The 
    Agency's issuance of a NOID would constitute the action required by 
    FIFRA section 3(h) to notify an applicant of the Agency's decision, and 
    the 30 days allowed for correction or other action would not be counted 
    in the computation of the review period. Alternatively, EPA may 
    determine that the application remains incomplete, in accordance with 
    paragraph (d)(2) of this section. In either case, any subsequent 
    submission will be treated as if it were an original application, and 
    the review period will start over upon receipt of a complete 
    application.
        (5) Deny the application for failure to meet the registration 
    standard. EPA may deny an application for registration if the Agency 
    determines that, based upon review of a complete application and all 
    data required by the Act, this part and part 158 of this chapter, the 
    product does not meet the criteria of FIFRA section 3(c)(5) or (7), as 
    specified in Sec. 152.112, Sec. 152.113, or Sec. 152.114. If EPA 
    proposes to deny an application on this basis, the Agency will follow 
    the procedures of Sec. 152.118. The Agency's issuance of a NOID would 
    constitute the action required by FIFRA section 3(h) to notify an 
    applicant of the Agency's decision, and the 30 days allowed for 
    correction or other action would not be counted in the computation of 
    the review period.
    
    
    Sec. 152.457   Review periods for applications.
    
        EPA will complete review of, and make a decision on whether to 
    approve, each application type listed in Sec. 152.445 within the review 
    periods given in this section. The statutory timeframes are based upon 
    submission of a complete application. The process of submission is not 
    complete until EPA has received the application. Accordingly, review 
    periods are computed from the date that EPA receives the last item of 
    an application that it determines thereafter is a complete application.
        (a) Applications involving food/feed uses. The time frames in this 
    section do not apply to applications involving food or feed uses that 
    may require a clearance under the FFDCA. EPA will attempt to review 
    such applications in a time commensurate with similar non-food actions, 
    but because these applications may require significantly more data and 
    more formal procedures for approval, EPA has not established any review 
    periods for such applications.
        (b) Fast-track applications. An application that qualifies as a 
    fast-track application under FIFRA section 3(c)(3)(B)(i) will be 
    reviewed within 90 days after receipt of a complete application.
        (c) Application for new registration. Except as provided in 
    paragraph (e) of this section, EPA will issue a decision on a complete 
    application for new registration within the review period listed in the 
    table to this paragraph.

        (f) Applicant recourse for failure to issue decision within review 
    period. If EPA has not notified the applicant that the application is 
    approved or denied within the review period set out in this section, or 
    within an alternative review period agreed to by EPA and the applicant, 
    the applicant may seek judicial review under 5 U.S.C. 7.
    
    
    Sec. 152.458   Duration of registration.
    
        (a) Products not bearing public health claims. The registration of 
    a product that bears no public health claim, as defined in Sec. 156.443 
    of this chapter, will be effective until EPA takes action to suspend or 
    cancel the registration.
        (b) Products bearing public health claims. The registration of a 
    product bearing a public health claim, as defined in Sec. 156.443 of 
    this chapter, will expire 5 years after the date specified in paragraph 
    (b)(1) or (b)(2) of this section, as applicable, unless the 
    requirements of paragraph (b)(3) of this section have been met. At the 
    end of each 5-year period thereafter, the registration will expire 
    unless the requirements of paragraph (b)(3) of this section have been 
    met with respect to the most recent 5-year period.
        (1) New products. The 5-year period for products first registered 
    after the effective date of this rule begins on the date of 
    registration. EPA will incorporate the 5-year term of registration in 
    the notice of registration.
        (2) Existing products. The 5-year period for products already 
    registered as of the effective date of this rule begins on the earliest 
    of the following dates:
        (i) The date of EPA approval of the first amendment after the 
    effective date of this rule. EPA will incorporate the 5-year term of 
    registration into the letter of approval.
        (ii) The date of EPA approval of reregistration of the product 
    under FIFRA section 4. EPA will incorporate the 5-year term of 
    registration into the letter of reregistration.
        (iii) A date certain approximately 1 year after the effective date 
    of this rule.
        (3) The registration will not expire if:
        (i) Within 1 year before each expiration date of the registration, 
    the registrant completes one or more chemical analyses of the product 
    according to the analytical method submitted under Sec. 158.180 of this 
    chapter.
        (ii) Within 1 year before each expiration date of the registration, 
    the registrant completes efficacy testing for each public health claim 
    on the label in accordance with the most current Agency guidelines.
        (iii) No later than 90 days before each expiration of the 
    registration, the registrant submits to the Office of Pesticide 
    Programs at EPA a written certification, signed by an authorized 
    representative of the registrant. The registrant must certify to each 
    of the following:
        (A) The registrant has conducted the required tests, identifying 
    the tests that were conducted.
        (B) Each test was conducted in accordance with the most current EPA 
    guidelines for product composition testing and efficacy testing, and 
    with applicable Good Laboratory Practice standards of part 160 of this 
    chapter.
        (C) Based upon the product composition tests, the product 
    composition continues to conform to the most recent Statement of 
    Formula approved by EPA.
        (D) Based upon the efficacy testing, the product meets applicable 
    performance standards of part 156, subpart W, for each public health 
    claim made.
        (E) The test results are maintained with the registrant and will be 
    submitted to EPA upon request.
        (4) If the registration expires, the product will be deemed to be 
    an unregistered product. EPA will permit the continued distribution and 
    sale of existing stocks of the product by the registrant for 90 days 
    after the expiration date, and by others for 1 year after the 
    expiration date, unless the Administrator determines that a different 
    time period is needed.
    
    
    Sec. 152.459   Terms and conditions of registration.
    
        (a) General conditions. A registration shall be subject to such 
    terms and conditions as EPA may establish at the time of issuance, 
    including, but not limited to, the terms and conditions in 
    Sec. 152.115. Such terms and conditions will be specified in the notice 
    of registration or letter approving an amendment of registration.
        (b) Submission of efficacy data for non-public health products. 
    Efficacy data for non-public health products are not generally required 
    to be submitted with an application for registration, but are required 
    to be maintained by the registrant. Upon request by EPA, the registrant 
    must submit the efficacy data required by part 158 for a non-public 
    health product. EPA will notify the registrant and allow 30 days from 
    date of receipt for submission of the data.

    Subpart D--Human Hazard and Precautionary Statements
    
    
    Sec. 156.60   General.
    
        Each product is required to bear hazard and precautionary 
    statements for humans and for domestic animals (if applicable) as 
    prescribed in this subpart. Hazard statements describe the type of 
    hazard that may occur, while precautionary statements will either 
    direct or inform the user of actions to take to avoid the hazard or 
    mitigate its effects.
        (a) Location of statements--(1) Front panel statements. The signal 
    word, child hazard warning, and, in certain cases, the first aid are 
    required to appear on the front panel of the label, and also in any 
    supplemental labeling intended to accompany the product in distribution 
    or sale.
        (2) Statements elsewhere on label. Hazard and precautionary 
    statements
    
    [[Page 50722]]
    
    not required on the front panel may appear on other panels of the 
    label, and may be required also in supplemental labeling. These 
    include, but are not limited to, the human hazard and precautionary 
    statements, domestic animal statements if applicable, Notes to 
    Physician, and physical or chemical hazard statements.
        (b) Placement and prominence--(1) Front panel statements. All 
    required front panel warning statements shall be grouped together on 
    the label, and shall appear with sufficient prominence relative to 
    other front panel text and graphic material to make them unlikely to be 
    overlooked under customary conditions of purchase and use. The table to 
    this paragraph shows the minimum type size requirements for the front 
    panel warning statements for various front panel sizes:

    Sec. 156.62   Toxicity category.
    
        This section establishes four Toxicity Categories for acute hazards 
    of pesticide products, Category I being the highest toxicity category. 
    Most human hazard, precautionary statements, and human personal 
    protective equipment statements are based upon the Toxicity Category of 
    the pesticide product as sold or distributed. In certain cases, 
    statements based upon the Toxicity Category of the product as diluted 
    for use are also permitted. A Toxicity Category is assigned for each of 
    five types of acute exposure, as specified in the table to this 
    paragraph.

    Sec. 156.64   Signal word.
    
        (a) Requirement. Except as provided in paragraph (a)(4) of this 
    section, each pesticide product must bear on the front panel a signal 
    word, reflecting the highest Toxicity Category (Category I is the 
    highest toxicity category) to which the product is assigned by any of 
    the five routes of exposure in Sec. 156.62. The signal word must also 
    appear together with the heading for the human precautionary statement 
    section of the labeling (see Sec. 156.70).
        (1) Toxicity Category I. Any pesticide product meeting the criteria 
    of Toxicity Category I for any route of exposure must bear on the front 
    panel the signal word ``DANGER.'' In addition, if the product is 
    assigned to Toxicity Category I on the basis of its oral, inhalation or 
    dermal toxicity (as distinct from skin and eye irritation), the word 
    ``Poison'' must appear in red on a background of distinctly contrasting 
    color, and the skull and crossbones symbol must appear in immediate 
    proximity to the word ``Poison.''
        (2) Toxicity Category II. Any pesticide product meeting the 
    criteria of Toxicity Category II as the highest category by any route 
    of exposure must bear on the front panel the signal word ``WARNING.''
        (3) Toxicity Category III. Any pesticide product meeting the 
    criteria of Toxicity Category III as the highest category by any route 
    of exposure must bear on the front panel the signal word ``CAUTION.''
        (4) Toxicity Category IV. A pesticide product meeting the criteria 
    of Toxicity Category IV by all routes of exposure is not required to 
    bear a signal word. If a signal word is used, it must be ``CAUTION.''
        (b) Use of signal words. In no case may a product:
    
    [[Page 50723]]
    
        (1) Bear a signal word reflecting a higher Toxicity Category than 
    indicated by the route of exposure of highest toxicity, unless the 
    Agency determines that such labeling is necessary to prevent 
    unreasonable adverse effects on man or the environment;
        (2) Bear a signal word reflecting a lesser Toxicity Category 
    associated with a diluted product. Although precautionary statements 
    for use dilutions may be included on label, the signal word must 
    reflect the toxicity of the product as distributed or sold; or
        (3) Bear different signal words on different parts of the label.
    
    
    Sec. 156.66   Child hazard warning.
    
        (a) Each pesticide product must bear on the front panel of the 
    label the statement ``Keep Out of Reach of Children.'' The statement 
    must appear on a separate line in close proximity to the signal word. 
    The statement is required on Toxicity Category IV products that do not 
    otherwise require a signal word.
        (b) EPA may waive the requirement, or require an alternative child 
    hazard warning, if:
        (1) The applicant can demonstrate that the likelihood of exposure 
    of children to the pesticide during distribution, marketing, storage or 
    use is remote (for example, an industrial use product); or
        (2) The pesticide is approved for use on children (for example, an 
    insect repellent).
        (c) EPA may approve an alternative child hazard warning that more 
    appropriately reflects the nature of the pesticide product to which 
    children may be exposed (for example, an impregnated pet collar). In 
    this case, EPA may also approve placement on other than the front 
    panel.
    
    
    Sec. 156.68   First aid statement.
    
        (a) Product as sold and distributed. Each product must bear a first 
    aid statement if the product has systemic effects in Category I, II, or 
    III, or skin or eye irritation effects in Category I or II. First aid 
    statements are based upon the Toxicity Category by each route of 
    exposure for the product.
        (b) Product as diluted for use. If the product labeling bears 
    directions for dilution with water prior to use, the label may also 
    include a statement describing how the first aid measures may be 
    modified for the diluted product. Such a statement must reflect the 
    Toxicity Category(ies) of the diluted product, based upon data for the 
    route of exposure (or calculations if appropriate). If the labeling 
    provides for a range of use dilutions, only that use dilution 
    representing the highest concentration allowed by labeling may be used 
    as the basis for a statement pertaining to the diluted product. The 
    statement for a diluted product may not substitute for the statement 
    for the concentrate, but augments the information provided for the 
    concentrate.
        (c) Heading. The heading of the statement must be ``First Aid.''
        (d) Location of first aid statement. The first aid statement must 
    appear on the front panel of the label of all products assigned to 
    Toxicity Category I by any route of exposure. Upon review, the Agency 
    may permit reasonable variations in the placement of the first aid 
    statement if a reference such as ``See first aid statement on back 
    panel'' appears on the front panel. The first aid statement for 
    products assigned to Toxicity Categories II or III may appear on any 
    panel of the label.
    
    
    Sec. 156.70   Precautionary statements for human hazards.
    
        (a) Requirement. Human hazard and precautionary statements as 
    required must appear together on the label or labeling under the 
    general heading ``Precautionary Statements'' and under appropriate 
    subheadings similar to ``Humans and domestic animals,'' ``Environmental 
    hazards'' (see subpart E of this part) and ``Physical or chemical 
    hazards.'' The phrase ``and domestic animals'' may be omitted from the 
    heading if domestic animals will not be exposed to the product.
        (b) Content of statements. When data or other information show that 
    an acute hazard may exist to humans or domestic animals, the label must 
    bear precautionary statements describing the particular hazard, the 
    route(s) of exposure and the precautions to be taken to avoid accident, 
    injury or toxic effect or to mitigate the effect. The precautionary 
    paragraph must be immediately preceded by the appropriate signal word.
        (c) Typical precautionary statements. The table to this paragraph 
    presents typical hazard and precautionary statements. Specific 
    statements pertaining to the hazards of the product and its uses must 
    be approved by the Agency. With Agency approval, statements may be 
    augmented to reflect the hazards and precautions associated with the 
    product as diluted for use. Refer to Sec. 156.68(b) for requirements 
    for use dilution statements.

    ------------------------------------------------------------------------
    
        (d) Total release fogger products. (1) A ``total release fogger'' 
    is defined as a pesticide product in a pressurized container designed 
    to automatically release the total contents in one operation, for the 
    purpose of creating a permeating fog within a confined space to deliver 
    the pesticide throughout the space.
        (2) If a pesticide product is at total release fogger containing a 
    propellant with a flash point at or below 20  deg.F, then the following 
    special instructions must be added to the ``Physical and Chemical 
    Hazards'' warning statement, in addition to any flammability statement 
    required by paragraph (b) of this section:
    
        This product contains a highly flammable ingredient. It may 
    cause a fire or explosion if not used properly. Follow the 
    Directions for Use on this label very carefully.
    
        (3) A graphic symbol depicting fire, such as illustrated in this 
    paragraph, or an equivalent symbol, must be displayed along with the 
    required language adjoining the ``Physical and Chemical Hazards'' 
    warning statement. The graphic symbol must be no smaller than twice the 
    size of the first character of the human hazard signal word.

        d. By adding new subpart E to read as follows:
    
    Subpart E--Environmental Hazard and Precautionary Statements
    
    Sec.
    156.80    General.
    156.85    Non-target organisms.
    Subpart E--Environmental Hazard and Precautionary Statements
    
    
    Sec. 156.80   General.
    
        (a) Requirement. Each product is required to bear hazard and 
    precautionary statements for environmental hazards, including hazards 
    to non-target organisms, as prescribed in this subpart. Hazard 
    statements describe the type of hazard that may be present, while 
    precautionary statements direct or inform the user of actions to take 
    to avoid the hazard or mitigate its effects.
        (b) Location of statements. Environmental hazard and precautionary 
    statements may appear on any panel of the label and may be
    
    [[Page 50725]]
    
    required also in supplemental labeling. The environmental hazard 
    statements must appear together under the heading ``Environmental 
    hazards.'' Typically the statements are grouped as a sub-category 
    within the ``Precautionary Statements'' section of the labeling.
        (c) Type size. All environmental hazard and precautionary 
    statements must be at least 6 point type.
    
    
    Sec. 156.85   Non-target organisms.
    
        (a) Requirement. Where a hazard exists to non-target organisms, EPA 
    may require precautionary statements of the nature of the hazard and 
    the appropriate precautions to avoid potential accident, injury, or 
    damage.
        (b) Examples. The statements in this paragraph illustrate the types 
    of hazard statements that EPA may require and the circumstances under 
    which they are typically required. These statements are not 
    comprehensive; other statements may be required if more appropriate to 
    the formulation or use.
        (1) If a pesticide intended for outdoor use contains an active 
    ingredient with a mammalian acute oral LD50 of 100 mg/kg or 
    less, the statement, ``This pesticide is toxic to wildlife'' is 
    required.
        (2) If a pesticide intended for outdoor use contains an active 
    ingredient with a fish acute LC50 of 1 ppm or less, the 
    statement, ``This pesticide is toxic to fish'' is required.
        (3) If a pesticide intended for outdoor use contains an active 
    ingredient with an avian acute oral LD50 of 100 mg/kg or 
    less, or a subacute dietary LC50 of 500 ppm or less, the 
    statement, ``This pesticide is toxic to wildlife'' is required.
        (4) If either accident history or field studies demonstrate that 
    the use of the pesticide may result in fatality to birds, fish or 
    mammals, the statement, ``This pesticide is extremely toxic to wildlife 
    (fish)'' is required.
        (5) If a product is intended for or involves foliar application to 
    agricultural crops, forests or shade trees, or mosquito abatement 
    treatments, and contains a pesticide toxic to pollinating insects, the 
    label must bear appropriate label cautions.
        (6) If a product is intended for outdoor use other than aquatic 
    applications, the label must bear the caution, ``Keep out of lakes, 
    ponds or streams. Do not contaminate water by cleaning of equipment or 
    disposal of wastes.''
        e. By adding new subpart W to read as follows:
    Subpart W--Public Health Claims for Antimicrobial Products
    Sec.
    156.440    Scope and applicability.
    156.441    Definitions.
    156.442    Use of terms and statements on labeling.

        Authority: 7 U.S.C. 136-136y.
    
    Sec. 156.440   Scope and applicability.
    
        (a) Scope--(1) Performance standards. This subpart establishes 
    performance standards for antimicrobial public health claims. The 
    performance standards are based upon required efficacy testing for 
    antimicrobial products specified in part 158 of this chapter. Test 
    methods and standards, evaluation procedures and reporting standards 
    referred to in this subpart are contained in the Pesticide Assessment 
    Guidelines, Subdivision G. This subpart does not cover performance 
    standards for non-public health claims.
        (2) Acceptable public health claim. This subpart describes public 
    health claims that may be made on antimicrobial product labeling based 
    upon efficacy performance standards. This subpart also establishes 
    limitations on the use of certain claims, as well as specific 
    antimicrobial claims that are not acceptable on product labeling. An 
    antimicrobial public health product that does not meet the performance 
    standard in this subpart for a public health claim may not bear that 
    claim.
        (3) Use directions. This subpart describes certain use directions 
    associated with public health claims, which are necessary to ensure 
    that the product will achieve the level of antimicrobial performance 
    claimed. This subpart does not set out use directions for non-public 
    health antimicrobial products, nor does it describe comprehensively the 
    use directions for public health products or claims, which are specific 
    to the use sites and patterns. Additional detailed guidance on use 
    directions for antimicrobial products is provided in the Pesticide 
    Assessment Guidelines, Subdivision H.
        (b) Applicability. (1) This subpart applies to any antimicrobial 
    product that is subject to the provisions of part 152, subpart W, and 
    that makes a public health claim.
        (2) This subpart applies to end use antimicrobial products. This 
    subpart does not apply to manufacturing use products.
    
    
    Sec. 156.441   Definitions.
    
        Terms defined in FIFRA and part 152 of this chapter are used with 
    the same definitions as given therein. In addition, the following terms 
    are defined for the purposes of this subpart:
        Disinfectant means a substance that destroys or eliminates a 
    specific species of infectious or other public health microorganism, 
    but not necessarily bacterial spores, in the inanimate environment.
        Equivalent, when used with respect to a test protocol or method, 
    means a test protocol or method, validated by multiple laboratory 
    studies and approved by EPA, that accomplishes the purposes intended by 
    the cited Guidelines test protocols, and that is expected to provide 
    data of equal quality and completeness as data derived from testing 
    according to an EPA Guideline protocol.
        Fungicide means a substance that destroys fungi (including yeasts) 
    and fungal spores pathogenic to man or other animals in the inanimate 
    environment.
        Guidelines means the Pesticide Assessment Guidelines, Subdivision G 
    - Product Performance Test Guidelines, or the Harmonized OPPTS Test 
    Guidelines, which are an updated, reformatted compilation of guidelines 
    used for both pesticide and other chemical testing.
        Microbiological water purifier means any unit, water treatment 
    product or system that removes, kills or inactivates all types of 
    disease-causing microorganisms from the water, including bacteria, 
    viruses and protozoan cysts, so as to render the treated water safe for 
    drinking.
        Public health product means an antimicrobial product that bears a 
    public health claim as defined in Sec. 156.443. A public health product 
    is also a ``public health pesticide'' as defined by FIFRA section 
    2(nn).
        Sanitizer means a substance that reduces the bacterial population 
    in the inanimate environment by significant numbers, but does not 
    destroy or eliminate all bacteria or other microorganisms.
    
    [[Page 50726]]
    
        Sterilant means a substance that destroys or eliminates all forms 
    of microbial life in the inanimate environment, including all forms of 
    vegetative bacteria, bacterial spores, fungi, fungal spores, and 
    viruses. For purposes of this subpart, ``sporicide'' and ``sterilant'' 
    are synonymous.
        Tuberculocide means a substance that destroys or irreversibly 
    inactivates tubercle bacilli in the inanimate environment.
        Virucide means a substance that destroys or inactivates viruses in 
    the inanimate environment.
    
    
    Sec. 156.442   Use of terms and statements on labeling.
    
        When this subpart authorizes the use of a term on product labeling, 
    other grammatical variants, phrases and statements having the same or 
    equivalent connotation are also authorized, unless EPA, on a case-by-
    case basis, prohibits their use. For example, authorization to use the 
    term ``sterilant'' also means that ``sterilizer,'' ``sterilization,'' 
    and similar terms may be used. EPA approves the content of each label, 
    and may, in its discretion, limit the use of certain terms, phrases or 
    statements.
    
    
    Sec. 156.443   Public health claims.
    
        EPA will consider a product to make a public health claim if any of 
    the following applies:
        (a) A claim is made for control of specific microorganisms or 
    classes of microorganisms that are directly or indirectly infectious or 
    pathogenic to man (or both man and animals). Examples of specific 
    microorganisms include Mycobacterium tuberculosis, Pseudomonas 
    aeruginosa, E. coli, HIV, Streptococcus, and Staphylococcus aureus. 
    Claims for control of microorganisms infectious or pathogenic only to 
    animals (such as canine distemper virus or hog cholera virus) are not 
    considered public health claims.
        (b) A claim is made for the product as a sterilant, disinfectant, 
    virucide, or sanitizer, regardless of the site of use of the product, 
    and regardless of whether specific microorganisms are identified.
        (c) A claim is made for the product as a fungicide against fungi 
    infectious or pathogenic to man, or the product does not clearly 
    indicate it is intended for use only against non-public health fungi.
        (d) A claim is made for the product as a microbiological water 
    purifier (see Sec. 156.457).
        (e) A non-specific claim is made that the product will beneficially 
    impact or affect public health at the site of use or in the environment 
    in which applied (such as a ``sanitary'' claim), and:
        (1) The product contains one or more ingredients that, under the 
    criteria in 40 CFR 153.125(a), is considered an active ingredient with 
    respect to a public health microorganism and there is no other 
    functional purpose for the ingredient in the product; or
        (2) The product is similar in composition to registered products 
    that make explicit antimicrobial public health claims.
    
    
    Sec. 156.444   Unacceptable statements and claims.
    
        No pesticide or device, including an antimicrobial pesticide 
    product, may bear false or misleading claims or statements (including 
    the name of the product). Claims or statements of the type identified 
    in this section are deemed to be false or misleading and are not 
    acceptable on antimicrobial product labeling. Effective on [date 
    certain - 1 year], EPA will regard an antimicrobial product bearing a 
    statement, claim, or product name that is unacceptable under this 
    section to be misbranded under FIFRA section 2(q).
        (a) Statements or claims that suggest or imply greater 
    effectiveness because of composition, e.g., ``hospital'' strength or 
    grade, ``industrial strength,'' ``extra strength.''
        (b) Statements or claims that suggest or imply that the product can 
    or will prevent or control disease or offer health protection. Claims 
    such as ``prevents infection,'' ``controls infection'' or ``prevents 
    cross-infection'' or that the product will control or mitigate any 
    disease (such as Legionnaire's disease), infection, or pathological 
    condition constitute drug claims regulated by the Food and Drug 
    Administration. A claim that the product ``controls cross-contamination 
    from treated surfaces,'' or ``kills [name of specific organism] in the 
    inanimate environment'' is acceptable.
        (c) Statements or claims that are overly broad, non-specific, 
    ambiguous or exaggerated.
        (1) The terms ``microbicide'' and ``microbistat'' are not 
    acceptable on a public health product. If used on a non-public health 
    product, the claim must be qualified to indicate that the product does 
    not provide public health protection.
        (2) The term ``biocide'' is unacceptable on a public health product 
    because it implies that the product can kill all living organisms, 
    including plants and animals. If used on a non-public health product, 
    the term must be qualified by directions for use or other statements 
    that make clear the types of organisms to be controlled.
        (3) The term ``antibacterial'' or ``germicidal'' is not acceptable 
    on a non-public health product. If used on a public health product, the 
    labeling must identify the specific organisms to be controlled.
        (4) The term ``antimicrobial'' is not acceptable on a non-public 
    health product, unless clearly and properly qualified to indicate that 
    the product does not provide public health protection. ``Clearly and 
    properly qualified'' means, at a minimum, that:
        (i) The term ``antimicrobial'' is clearly associated with, and in 
    close proximity to, its qualifying statement on the labeling. It is 
    always unacceptable for the term ``antimicrobial'' to appear on a 
    different label panel from its qualifying statement.
        (ii) The term ``antimicrobial'' is not highlighted or given 
    prominence over the qualifying statement by means of placement or 
    presentation (e.g., type size, style, color or contrast).
        (iii) The term ``antimicrobial'' is not part of the product name.
        (5) The prefix ``steri-'' implies sterilant activity, and may not 
    be used in the product name or on a product that is not a sterilant.
        (6) Statements or claims implying indefinite or all-encompassing 
    antimicrobial protection against bacteria, fungi or algae (``germ-
    free,'' ``mildew-proof,'' ``algae-free'') are not acceptable.
        (d) Claims or statements that differ from or do not accurately 
    reflect the results demonstrated by testing.
        (1) Product names, or claims or statements expressing or implying a 
    higher level of antimicrobial activity than that demonstrated by 
    testing, even if qualified (for example, ``sterisure bacteriostat''). 
    The labeling must unambiguously identify the level of antimicrobial 
    activity (disinfectant, sanitizer, etc).
        (2) Claims or statements that are inconsistent with conditions of 
    efficacy established by testing (e.g., a claim of efficacy within 30 
    seconds, when testing and use directions require 2 minutes contact time 
    for efficacy.)
        (e) Statements or claims of efficacy based on unsubstantiated, 
    improbable or irrelevant site/pest relationships. For example, a claim 
    of efficacy against a pest not likely to occur on the site (e.g., 
    athlete's foot fungi in toilet bowls) is misleading.
        (f) A statement or claim of presumptive or screening efficacy, even 
    if qualified, is not acceptable on an end use product. Presumptive 
    efficacy testing is intended to demonstrate that an active ingredient 
    is capable of antimicrobial efficacy, but such testing is not conducted 
    under specific conditions of use. An end use product
    
    [[Page 50727]]
    
    must be tested for, demonstrate, and be labeled for a specific level of 
    antimicrobial efficacy against identified organisms under conditions of 
    use likely to be encountered.
        (1) Legionnaire's disease claims in cooling tower water are not 
    acceptable. Express or implied claims that a product will prevent 
    growth or spread of Legionnaire's Disease bacteria (LDB) are 
    unacceptable. Product labeling may provide accurate information 
    concerning current knowledge and recommendations of the Public Health 
    Service, or laboratory test data showing presumptive effectiveness of 
    the product against pure cultures of LDB. Such information must be 
    qualified by statements to the effect that findings are presumptive, 
    and that there is no evidence that chemical treatment will control LDB 
    growth under actual use conditions, reduce transmission of LDB, or 
    prevent Legionnaire's Disease.
        (2) No statement of phenol coefficient may appear on a public 
    health end use product. The phenol coefficient is a calculated 
    comparison of presumptive efficacy.
        (g) Certain symbols, icons, or graphics are unacceptable.
        (1) The caduceus symbol is not acceptable because it is a medical 
    symbol that implies endorsement by the medical profession or broad 
    medical significance or health protection that is not acceptable in 
    accordance with paragraph (b) of this section.
        (2) The name and symbol of the Red Cross are not permitted on any 
    product.
    
    
    Sec. 156.445   Sterilant claim on hard surfaces.
    
        (a) Performance standard. (1) When tested in accordance with the 
    test methods and standards in OPPTS 810.2100(b)(1) and (2) of the 
    guidelines or its equivalent, the product kills all test spores on all 
    carriers with no failures; and
        (2) When tested by a laboratory independent of the registrant in 
    accordance with the test methods and standards in OPPTS 810.2100(b)(4) 
    of the guidelines or its equivalent, the product kills all test spores 
    on all carriers with no failures.
        (b) Acceptable claim. (1) A product that meets the performance 
    standard in paragraph (a) may bear ``sterilant'' claims or variants of 
    these.
        (2) Since a sterilizer by definition destroys or eliminates all 
    forms of microbial life, a sterilant product may bear claims of any 
    lesser efficacy levels, such as disinfectant, bactericidal, 
    tuberculocidal, fungicidal, virucidal or sanitizer. Separate directions 
    for use must be provided for each lesser level of antimicrobial 
    activity.
        (c) Unacceptable claims. (1) Liquid chemical germicides may not 
    make sterilant claims for critical or semi-critical medical devices. 
    Claims for liquid chemical germicides are limited to pre-cleaning 
    critical or semi-critical medical devices prior to sterilization.
        (2) ``One-step'' claims are not allowed for sterilants. The label 
    must require pre-cleaning of surfaces prior to sterilization.
    
    
    Sec. 156.446   Disinfectant claim on hard surfaces.
    
        (a) Performance standard. (1) When tested in accordance with the 
    test methods and standards in OPPTS 810.2100(c), (d), or (e) of the 
    guidelines or its equivalent, the product kills the test microorganisms 
    on 59 out of each set of 60 carriers/slides. Although the performance 
    standard is the same for all disinfectant claims, the test standards 
    and test microorganisms define the level of disinfectant claim that may 
    be made on product labeling.
        (2) An applicant who wishes to make disinfectant claims for 
    additional microorganisms not designated in the test methods and 
    standards may do so based upon efficacy tests conducted with those 
    additional microorganisms. When tested in accordance with the test 
    methods and standards in OPPTS 810.2100(k) of the guidelines or its 
    equivalent, for each organism the product must kill all test organisms 
    on 10 carriers for each of two samples representing two different 
    batches.
        (b) Acceptable limited disinfectant claim--(1) Products containing 
    pine oil. A product containing pine oil (as sole active ingredient or 
    in combination with other ingredients) and that meets the performance 
    standard in paragraph (a) when tested using the test standards in OPPTS 
    810.2100(c) of the guidelines or its equivalent and the test 
    microorganism Salmonella cholerasuis may bear only a claim as a 
    ``limited disinfectant against bacteria of intestinal origin.''
        (2) All other products. A product that meets the performance 
    standard in paragraph (a) of this section for only one major group of 
    microorganisms (Gram negative or Gram positive bacteria) when tested 
    using the test standards of OPPTS 810.2100(c) of the guidelines or its 
    equivalent may bear only a claim as a ``limited disinfectant.'' The 
    product labeling must identify the specific organisms against which the 
    product is effective.
        (c) Acceptable general or broad spectrum disinfectant claim. A 
    product that meets the performance standard in paragraph (a) of this 
    section for both Gram negative and Gram positive bacteria when tested 
    using the test standards of OPPTS 810.2100(d) of the guidelines or its 
    equivalent may bear a claim as a ``general or broad spectrum 
    disinfectant,'' and may also bear a claim as a ``hard food contact 
    surface disinfectant.'' The product labeling must identify the specific 
    organisms against which the product is effective.
        (d) Acceptable hospital or medical disinfectant claim. A product 
    that meets the performance standard in paragraph (a) of this section 
    when tested in accordance with the test standard in OPPTS 810.2100(e) 
    of the guidelines or its equivalent may bear a claim as a ``hospital or 
    medical environment disinfectant,'' and may also bear a claim as a 
    ``hard food contact surface disinfectant.'' The product labeling must 
    identify the specific organisms against which the product is effective.

    its equivalent), it meets the performance standard in OPPTS 
    810.2100(i)(3)(i) of the guidelines or its equivalent.
        (2) Multiple use towelettes. A multiple use towelette may bear a 
    claim as a ``multiple use towelette for the disinfection of hard 
    surfaces'' if, when tested by the methods and standards approved by EPA 
    (OPPTS 810.2100(i)(1)(ii) of the guidelines or its equivalent), it 
    meets the performance standard in OPPTS 810.2100(i)(3)(ii) of the 
    guidelines or its equivalent.
        (f) Unacceptable claims. (1) A product that functions by fogging 
    may not bear claims of disinfection for duct systems, air, or room 
    surfaces.
        (2) Products with circulate-in-place (CIP) applications may not 
    bear claims of disinfection because CIP application has not been shown 
    to be effective in disinfecting duct systems, air or room surfaces. CIP 
    products may, however, bear claims of sanitization if they meet the 
    performance standard of Sec. 156.451.
