    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Food and Drug Administration (FDA) is proposing to clarify 
    the criteria for exempting the use of a substance in human food or in 
    animal feed from the premarket approval requirements of the Federal 
    Food, Drug, and Cosmetic Act (the act) because such use is generally 
    recognized as safe (GRAS). FDA is also proposing to replace the current 
    GRAS affirmation process with a notification procedure whereby any 
    person may notify FDA of a determination that a particular use of a 
    substance is GRAS. Under the proposed notification procedure, the 
    agency intends to evaluate whether the submitted notice provides a 
    sufficient basis for a GRAS determination and whether information in 
    the notice or otherwise available to FDA raises issues that lead the 
    agency to question whether use of the substance is GRAS. This proposal 
    reflects FDA's commitment to achieving the goals for the Reinventing 
    Food Regulations part of the President's National Performance Review 
    (hereinafter referred to as Reinventing Food Regulations). The proposed 
    notification procedure would allow FDA to direct its resources to 
    questions about GRAS status that are a priority with respect to public 
    health protection.
    
    DATES: Written comments by July 16, 1997, except that comments 
    regarding information collection should be submitted by May 19, 1997. 
    The agency proposes that any final rule that may issue based on this 
    proposal become effective 60 days after its date of publication.

    I. Background
    
    A. The 1958 Amendment
    
        In 1958, in response to public concern about the increased use of 
    chemicals in foods and food processing and with the support of the food 
    industry, Congress enacted the Food Additives Amendment (the 1958 
    amendment) to the act. The basic thrust of the 1958 amendment was to 
    require that, before a new additive could be used in food, its producer 
    demonstrate the safety of the additive to FDA. The 1958 amendment 
    defined the terms ``food additive'' (section 201(s) of the act (21 
    U.S.C. 321(s))) and ``unsafe food additive'' (section 409(a) of the act 
    (21 U.S.C. 348(a))), established a premarket approval process for food 
    additives (section 409(b) through (h)), and amended the food 
    adulteration provisions of the act to deem adulterated any food that 
    is, or bears or contains, any food additive that is unsafe within the 
    meaning of section 409 (section 402(a)(2)(C) of the act (21 U.S.C. 
    342(a)(2)(C))).
        Congress recognized that, under this scheme, the safety of an 
    additive could not be established with absolute certainty, and thus 
    provided for a science-based safety standard that requires producers of 
    food additives to demonstrate to a reasonable certainty that no harm 
    will result from the intended use of an additive (Ref. 1). FDA has 
    incorporated this safety standard into its regulations (Sec. 170.3(i) 
    (21 CFR 170.3(i))). If FDA finds an additive to be safe, based 
    ordinarily on data submitted by the producer to the agency in a food 
    additive petition (FAP), the agency issues a regulation specifying the 
    conditions under which the additive may be safely used.
        In enacting the 1958 amendment, Congress recognized that many 
    substances intentionally added to food would not require a formal 
    premarket review by FDA to assure their safety, either because their 
    safety had been established by a long history of use in
    
    [[Page 18939]]
    
    food or by virtue of the nature of the substances, their customary or 
    projected conditions of use, and the information generally available to 
    scientists about the substances. Congress thus adopted, in section 
    201(s) of the act, a two-step definition of ``food additive.'' The 
    first step broadly includes any substance, the intended use of which 
    results or may reasonably be expected to result, directly or 
    indirectly, in its becoming a component or otherwise affecting the 
    characteristics of food. The second step, however, excludes from the 
    definition of ``food additive'' substances that are generally 
    recognized, among experts qualified by scientific training and 
    experience to evaluate their safety (``qualified experts''), as having 
    been adequately shown through scientific procedures (or, in the case of 
    a substance used in food prior to January 1, 1958, through either 
    scientific procedures or through experience based on common use in 
    food) to be safe under the conditions of their intended use.
        Importantly, under section 201(s) of the act, it is the use of a 
    substance, rather than the substance itself, that is eligible for the 
    GRAS exemption. In addition, it is well settled that a mere showing 
    that use of a substance is ``safe'' is not sufficient to exempt the 
    substance from the act's definition of ``food additive'' (United States 
    v. An Article of Food * * * Coco Rico, Inc., 752 F.2d 11, 15 n. 4 (1st 
    Cir. 1985)). Instead, the substance must be shown to be ``generally 
    recognized'' as safe under the conditions of its intended use (Id.; 
    United States v. Articles of Food and Drug * * * Coli-Trol 80, 518 F.2d 
    743, 745 (5th Cir. 1975)). The proponent of the exemption has the 
    burden of proving that the use of the substance is ``generally 
    recognized'' as safe (Id). To establish such recognition, the proponent 
    must show that there is a consensus of expert opinion regarding the 
    safety of the use of the substance. (See United States v. Western Serum 
    Co., Inc., 666 F.2d 335, 338 (9th Cir. 1982); United States v. Articles 
    of Drug * * * Promise Toothpaste, 624 F.Supp. 776, 778 (N.D. Ill. 
    1985), aff'd 826 F.2d 564 (7th Cir. 1987); United States v. Articles of 
    Drug * * * Hormonin, 498 F.Supp.2d 424, 435 (D.N.J. 1980).) Unanimity 
    among experts regarding safety of a substance is not required. (See 
    United States v. Articles of Drug * * * 5,906 boxes, 745 F.2d 105, 119 
    n. 22 (1st Cir. 1984); United States v. An Article of Drug * * * 4,680 
    Pails, 725 F.2d 976, 990 (5th Cir. 1984); Coli-Trol 80, supra, 518 F.2d 
    at 746; Promise Toothpaste, supra, 624 F.Supp. at 782.) However, the 
    existence of a severe conflict among experts regarding the safety of 
    the use of a substance precludes a finding of general recognition 
    (4,680 Pails, supra, 725 F.2d at 990; Premo Pharmaceutical Laboratories 
    v. United States, 629 F.2d 795, 803 (2d Cir. 1980)) (Cf. Coli-Trol 80, 
    supra, 518 F.2d at 746 (mere conflict among experts is not enough to 
    preclude a finding of general recognition)).
        It is on the basis of the GRAS exemption to the food additive 
    definition that many substances (such as vinegar, vegetable oil, baking 
    powder, and many salts, spices, flavors, gums, and preservatives) are 
    lawfully marketed today without a food additive regulation. Under the 
    1958 amendment, a substance that is GRAS for a particular use may be 
    marketed for that use without agency review and approval. However, when 
    a use of a substance does not qualify for the GRAS exemption or other 
    exemptions provided under section 201(s) of the act, that use of the 
    substance is a food additive use subject to the premarket approval 
    mandated by the act. In such circumstances, the agency can take 
    enforcement action to stop distribution of the food substance and foods 
    containing it on the grounds that such foods are or contain an unlawful 
    food additive.
        Importantly, under section 201(s) of the act, the GRAS exemption 
    applies to the premarket approval requirements for food additives only. 
    There is no corresponding exemption to the premarket approval 
    requirements for color additives, which are defined in section 201(t) 
    of the act.
    
    B. History of FDA's Approach to the GRAS Exemption
    
    1. The GRAS List
        Shortly after passage of the 1958 amendment, FDA clarified the 
    regulatory status of a multitude of food substances that were used in 
    food prior to 1958 and amended its regulations to include a list of 
    food substances that, when used for the purposes indicated and in 
    accordance with current good manufacturing practice, are GRAS. This 
    list was incorporated into the agency's regulations as Sec. 121.101(d) 
    (now parts 182 and 582 (21 CFR parts 182 and 582)) (24 FR 9368, 
    November 20, 1959). As part of that rulemaking, however, FDA 
    acknowledged that it would be impracticable to list all substances that 
    are GRAS for their intended use (formerly Sec. 121.101(a); current 
    Sec. 182.1(a)).
        Section 121.101(d) became commonly referred to as ``the GRAS 
    list.'' FDA added other categories of substances (e.g., spices, 
    seasonings, and flavorings) to the GRAS list in subsequent rulemakings 
    (25 FR 404, January 19, 1960; and 26 FR 3991, May 9, 1961).
    2. Opinion Letters
        Many substances that were considered GRAS by the food industry were 
    not included in the agency's GRAS list. Under the 1958 amendment, a 
    substance that is GRAS for a particular use may be marketed for that 
    use without agency review and approval. Nonetheless, as a practical 
    matter, manufacturers who determined on their own initiative that use 
    of a substance qualified for the GRAS exemption frequently decided to 
    obtain the agency's opinion on whether their determination was 
    justified. Many manufacturers wrote to FDA and requested an ``opinion 
    letter,'' in which agency officials would render an informal opinion on 
    the GRAS status of use of a substance. Although convenient and 
    expedient, these opinion letters were often available only to the 
    requestor. Moreover, these opinion letters were not binding on the 
    agency at the time they were issued and were in fact formally revoked 
    in 1970 (21 CFR 170.6, 35 FR 5810, April 9, 1970).
    3. Agency-Initiated GRAS Review
        In 1969 (34 FR 17063, October 21, 1969), FDA removed various 
    cyclamate salts, a family of nonnutritive sweeteners, from the GRAS 
    list because they were implicated in the formation of bladder tumors in 
    rats (Ref. 2). In response to the concerns raised by the new 
    information on cyclamates, then-President Nixon directed FDA to 
    reexamine the safety of GRAS substances (Ref. 3), and FDA announced 
    that the agency was conducting a comprehensive study of substances 
    presumed to be GRAS (35 FR 18623, December 8, 1970). The purpose of the 
    study was to evaluate, by contemporary standards, the available safety 
    information regarding substances presumed to be GRAS and to issue each 
    item in a new (i.e., affirmed) GRAS list, a food additive regulation, 
    or an interim food additive regulation pending completion of additional 
    studies.
    4. GRAS Criteria and the GRAS Affirmation Process
        In the notice announcing the comprehensive agency review of 
    presumed GRAS substances, FDA proposed criteria that could be used to 
    establish whether these substances should be listed as GRAS, become the 
    subject of a food additive regulation, or be listed in an interim food 
    additive
    
    [[Page 18940]]
    
    regulation pending completion of additional studies (35 FR 18623). 
    These criteria were incorporated into the agency's regulations as 
    Sec. 121.3 (precursor of current Sec. 170.30 (21 CFR 170.30)) (36 FR 
    12093, June 25, 1971).
        FDA made a second announcement that it was conducting a study of 
    presumed GRAS substances (36 FR 20546, October 23, 1971) and 
    subsequently instituted a rulemaking to establish procedures that the 
    agency could use, on its own initiative, to affirm the GRAS status of 
    substances that were the subject of that review and were found to 
    satisfy the criteria established in Sec. 121.3 (proposed rule, 37 FR 
    6207, March 25, 1972; final rule, 37 FR 25705, December 2, 1972). These 
    procedures were subsequently codified at Sec. 170.35 (a) and (b) (21 
    CFR 170.35 (a) and (b)). Because the GRAS review did not cover all GRAS 
    substances (e.g., it did not cover many substances that were marketed 
    based on a manufacturer's independent GRAS determination), that 
    rulemaking included a mechanism (the current GRAS petition process; 
    Sec. 170.35(c)) whereby an individual could petition FDA to review the 
    GRAS status of substances not being considered as part of the agency's 
    GRAS review.
        In 1974, the agency proposed to clarify the criteria for GRAS 
    status, the differences between GRAS status and food additive status, 
    and the procedures being used to conduct the current review of food 
    substances (39 FR 34194, September 23, 1974). The final regulations 
    based on this proposal amended Sec. 121.3 (current Sec. 170.30) to 
    distinguish a determination of GRAS status through scientific 
    procedures (scientific procedures GRAS determination; current 
    Sec. 170.30(b)) from a determination of GRAS status through experience 
    based on common use in food (common use GRAS determination; current 
    Sec. 170.30(c)) (41 FR 53600, December 7, 1976). Those final 
    regulations also established definitions for ``common use in food'' 
    (current Sec. 170.3(f)) and ``scientific procedures'' (current 
    Sec. 170.3(h)). FDA subsequently added criteria (Sec. 170.30(c)(2)) for 
    the determination of GRAS status through experience based on common use 
    in food when that use occurred exclusively or primarily outside of the 
    United States (53 FR 16544, May 10, 1988).
    5. The Plant Policy Statement
        FDA's ``Statement of Policy: Foods Derived From New Plant 
    Varieties'' (the plant policy statement) (57 FR 22984, May 29, 1992) is 
    an example of a recent agency policy announcement regarding agency 
    priorities in reviewing the GRAS status of substances added to food. In 
    the plant policy statement, FDA reviewed its position on the 
    applicability of the food additive definition and section 409 of the 
    act to foods derived from new plant varieties in light of the intended 
    changes in the composition of foods that might result from the newer 
    techniques of genetic modification such as recombinant deoxyribonucleic 
    acid (rDNA) techniques:
    
        The statutory definition of ``food additive'' makes clear that 
    it is the intended or expected introduction of a substance into food 
    that makes the substance potentially subject to food additive 
    regulation. Thus, in the case of foods derived from new plant 
    varieties, it is the transferred genetic material and the intended 
    expression product or products that could be subject to food 
    additive regulation, if such material or expression products are not 
    GRAS.
    
    (57 FR 22984 at 22990)
        In the plant policy statement, FDA provided extensive guidance, 
    including criteria and analytical steps that producers could follow, on 
    situations in which producers should consult with FDA to determine 
    whether an FAP is appropriate. FDA also stated its intent to use its 
    food additive authority in regulating foods and their byproducts 
    derived from new plant varieties to the extent necessary to protect 
    public health.
    
    C. Elements of the GRAS Standard
    
        Under section 201(s) of the act, a substance is exempt from the 
    definition of food additive and thus, from premarket approval 
    requirements, if its safety is generally recognized by qualified 
    experts. Accordingly, a determination that a particular use of a 
    substance is GRAS requires both technical evidence of safety and a 
    basis to conclude that this technical evidence of safety is generally 
    known and accepted. In contrast, a determination that a food additive 
    is safe requires only technical evidence of safety.1 Thus, a GRAS 
    substance is distinguished from a food additive on the basis of the 
    common knowledge about the safety of the substance for its intended use 
    rather than on the basis of what the substance is or the types of data 
    and information that are necessary to establish its safety. To 
    emphasize this distinction between a GRAS substance and a food 
    additive, and to simplify discussion about the standard for general 
    recognition of safety, in this document, FDA uses the term ``technical 
    element'' when discussing technical evidence of safety and ``common 
    knowledge element'' when discussing general knowledge and acceptance of 
    safety.
    ---------------------------------------------------------------------------
    
        \1\ In issuing a food additive regulation, the agency considers 
    technical evidence of safety but does not address the GRAS standard 
    of general recognition. Thus, in most cases, the agency's issuance 
    of a food additive regulation means that FDA did not consider the 
    possible GRAS status of that substance. In a few cases (e.g., 21 CFR 
    173.357, cellulose triacetate used as a fixing agent in the 
    immobilization of lactase enzyme preparation), FDA concluded, in 
    evaluating the GRAS status of a substance, that the safety of a use 
    of a substance was not generally recognized and authorized its use 
    as a food additive rather than affirm it as GRAS (59 FR 36935, July 
    20, 1994).
    ---------------------------------------------------------------------------
    
        The technical element of the GRAS standard requires that 
    information about the substance establish that the intended use of the 
    substance is safe. As discussed in section I.A of this document, FDA 
    has defined ``safe'' (Sec. 170.3(i)) as a reasonable certainty in the 
    minds of competent scientists that the substance is not harmful under 
    its intended conditions of use. Current Sec. 170.30(b) provides that 
    general recognition of safety through scientific procedures requires 
    the same quantity and quality of scientific evidence as is required to 
    obtain approval of the substance as a food additive. Similarly, current 
    Sec. 170.30(c)(1) provides that general recognition of safety through 
    experience based on common use in food prior to January 1, 1958, may be 
    determined without the quantity or quality of scientific procedures 
    required for approval of a food additive regulation and must be based 
    solely on food use of the substance prior to that date. Current 
    Sec. 170.3(f) defines ``common use in food'' as a substantial history 
    of consumption for food use by a significant number of consumers.
        The common knowledge element of the GRAS standard includes two 
    facets: (1) The data and information relied on to establish the 
    technical element must be generally available; and (2) there must be a 
    basis to conclude that there is consensus among qualified experts about 
    the safety of the substance for its intended use. Neither facet is, by 
    itself, sufficient to satisfy the common knowledge element of the GRAS 
    standard.
        The usual mechanism to establish that scientific information is 
    generally available is to show that the information is published in a 
    peer-reviewed scientific journal. However, mechanisms to establish the 
    basis for concluding that there is expert consensus about the safety of 
    a substance are more varied. In some cases, publication in a peer-
    reviewed scientific journal of data (such as toxicity studies) on a 
    test substance has been used to establish expert consensus in addition 
    to general availability. In other cases, such publication of data and 
    information in the primary
    
    [[Page 18941]]
    
    scientific literature has been supplemented by: (1) Publication of data 
    and information in the secondary scientific literature, such as 
    scientific review articles, textbooks, and compendia; (2) documentation 
    of the opinion of an ``expert panel'' that is specifically convened for 
    this purpose; or (3) the opinion or recommendation of an authoritative 
    body such as the National Academy of Sciences (NAS) or the Committee on 
    Nutrition of the American Academy of Pediatrics (CON/AAP) on a broad or 
    specific issue that is related to a GRAS determination.
        In this document, FDA is using the term ``consensus'' in discussing 
    the common knowledge element of the GRAS standard. Such consensus does 
    not require unanimity among qualified experts (5,906 boxes, supra, 745 
    F.2d at 119 n. 22; United 4,680 Pails, supra, 725 F.2d at 990; Coli-
    Trol 80, supra, 518 F.2d at 746; Promise Toothpaste, supra, 624 F.Supp. 
    at 782). For example, FDA would evaluate a single published report 
    questioning the safety of use of a substance in food in the context of 
    all the publicly available and corroborative information rather than 
    conclude that such a report automatically disqualifies the substance 
    from satisfying the GRAS standard (Cf. Coli-Trol 80, supra, 518 F.2d at 
    746).
    
    D. The GRAS Petition Process
    
        The rulemaking process in Sec. 170.35(c) whereby manufacturers may 
    petition FDA to affirm that a substance is GRAS under certain 
    conditions of use was designed as a voluntary administrative process 
    whose purpose was to provide a mechanism for official recognition of 
    lawfully made GRAS determinations. To the extent that a person elected 
    to submit a GRAS petition, the process could facilitate an awareness, 
    by the agency as well as the domestic and international food industry, 
    of independent GRAS determinations. However, GRAS affirmation involves 
    the resource-intensive rulemaking process, including: (1) Publishing a 
    filing notice in the Federal Register; (2) requesting comment on the 
    petitioned request; (3) conducting a comprehensive review of the 
    petition's data and information and comments received to the filing 
    notice to determine whether the evidence establishes that the 
    petitioned use of the substance is GRAS; (4) drafting a detailed 
    explanation of why the use is GRAS (as opposed to simply being safe); 
    and (5) publishing that explanation in the Federal Register. FDA 
    believes that, in practice, this resource-intensive process deters many 
    persons from petitioning the agency to affirm their independent GRAS 
    determinations.
    
    II. Scope of the Proposed Regulations
    
        Based on its experience applying the provisions of Sec. 170.30, FDA 
    is proposing to clarify when use of a substance is exempt from the 
    act's premarket approval requirements because such use is GRAS. In 
    proposing these changes, FDA is: (1) Emphasizing that a GRAS substance 
    is distinguished from a food additive by the common knowledge about the 
    safety of the substance for its intended use rather than by what the 
    substance is, or on the basis of the types of data and information that 
    are necessary to establish its safety; (2) identifying the types of 
    technical evidence of safety that could form the basis of a GRAS 
    determination; and (3) clarifying the role of publication in satisfying 
    the general recognition standard. For consistency with the proposed 
    changes to Sec. 170.30, FDA is also proposing to amend the definition 
    in Sec. 170.3(h) of ``scientific procedures.''
        In addition, in keeping with the Reinventing Food Regulations, FDA 
    is proposing to replace the current GRAS affirmation petition process 
    (Sec. 170.35(c)) with a notification procedure (proposed Sec. 170.36) 
    whereby any person may notify FDA of a determination that a particular 
    use of a substance is GRAS. The submitted notice would include a ``GRAS 
    exemption claim'' that would provide specific information about a GRAS 
    determination in a consistent format. This GRAS exemption claim would 
    include a succinct description of the ``notified substance'' (i.e., the 
    substance that is the subject of the notice), the applicable conditions 
    of use, and the basis for the GRAS determination (i.e., through 
    scientific procedures or through experience based on common use in 
    food) and would be dated and signed by the notifier. The GRAS exemption 
    claim also would include a statement that the information supporting 
    the GRAS determination was available for FDA review and copying or 
    would be sent to FDA upon request. In addition to the GRAS exemption 
    claim, the notice would include detailed information about the identity 
    and properties of the notified substance and a detailed discussion of 
    the basis for the notifier's GRAS determination.
        Under the proposed notification procedure, the agency intends to 
    evaluate whether the notice provides a sufficient basis for a GRAS 
    determination and whether information in the notice or otherwise 
    available to FDA raises issues that lead the agency to question whether 
    use of the substance is GRAS. Within 90 days of receipt of the notice, 
    FDA would respond to the notifier in writing and could advise the 
    notifier that the agency has identified a problem with the notice. 
    Although information in a notice would be publicly available consistent 
    with the Freedom of Information Act (FOIA), FDA would make readily 
    accessible to the public the notice's GRAS exemption claim, as well as 
    the agency's response to the notice. However, FDA does not intend to 
    conduct its own detailed evaluation of the data that the notifier 
    relies on to support a determination that a use of a substance is GRAS 
    or to affirm that a substance is GRAS for its intended use.
        FDA has tentatively concluded that the proposed notification 
    procedure has advantages over the current petition process because the 
    resource-intensive rulemaking that is associated with a petition would 
    be eliminated. This streamlining would allow FDA to redirect its 
    resources to questions about GRAS status that are a priority with 
    respect to public health protection. In addition, the proposed notice 
    is simpler than a GRAS affirmation petition and therefore conceivably 
    would provide an incentive for manufacturers to inform FDA of their 
    GRAS determinations. This would result in increased agency awareness of 
    the composition of the nation's food supply and the cumulative dietary 
    exposure to GRAS substances. FDA has also tentatively concluded that 
    the public health would be better served if some resources that are 
    currently directed to the GRAS petition process were redirected to the 
    preparation of documents that would provide the industry with guidance 
    on certain food safety issues for complex substances (e.g., 
    macroingredients or biological polymers, such as proteins, 
    carbohydrates, and fats and oils). Finally, the reduction in resources 
    devoted to the evaluation of GRAS substances would allow FDA to shift 
    resources to its statutorily mandated task of reviewing food and color 
    additive petitions.
        In light of its experience in reviewing GRAS petitions, FDA 
    believes that the substitution of the proposed notification procedure 
    for the current GRAS petition process would not adversely affect the 
    public health because the agency would be replacing one voluntary 
    administrative process with a different voluntary administrative 
    procedure that would utilize FDA's resources more effectively and 
    efficiently. Under both the current and the proposed procedures, a 
    manufacturer may market a substance that the manufacturer determines is 
    GRAS without informing the agency or, if the agency is so
    
    [[Page 18942]]
    
    informed, while the agency is reviewing that information. Thus, from a 
    legal and regulatory perspective, this substitution is neutral.
        FDA is also proposing to remove Sec. 170.30(f), which expresses the 
    agency's intent to review the GRAS status of certain food substances, 
    because Sec. 170.30(f) is redundant with the provisions of Sec. 170.35 
    (a) and (b) that the agency may, on its own initiative, affirm the GRAS 
    status of substances that directly or indirectly become components of 
    food (Sec. 170.35(a)) or publish a notice announcing its conclusion 
    that there is a lack of convincing evidence that the substance is GRAS 
    and that it should be considered a food additive (Sec. 170.35(b)).
        FDA's regulations regarding the eligibility of substances used in 
    animal food or feeds for classification as GRAS, and the procedures for 
    affirmation of GRAS status for such substances, are codified at 
    Secs. 570.30 and 570.35 (21 CFR 570.30 and 570.35), respectively. FDA 
    is proposing the following: (1) To amend the provisions of Sec. 570.30 
    that are parallel to the provisions of current Sec. 170.30 (i.e., 
    Sec. 570.30 (a) and (b)); (2) to eliminate the GRAS affirmation 
    petition process provided for in Sec. 570.35 (a) and (c); and (3) to 
    provide the option of a GRAS notification procedure for animal food or 
    feeds that would be parallel to proposed Sec. 170.36. FDA is proposing 
    these changes because the regulations in part 570 (21 CFR part 570) 
    implement the same statutory provisions as the regulations in part 170 
    (21 CFR part 170).
        Finally, FDA is proposing to make certain conforming amendments to 
    Secs. 170.38, 184.1, 186.1, and 570.38.
        As FDA gains experience with the questions raised by industry in 
    preparing notices, FDA expects, from time to time, to prepare guidance 
    documents on issues of particular interest. However, such guidance 
    documents are not a subject of this proposal.
    
    III. Proposed Revisions to Sec. 170.30--Eligibility for 
    Classification as GRAS
    
    A. General Criteria
    
        FDA is proposing to expand the description of the general criteria 
    provided in current Sec. 170.30(a) for a GRAS determination. FDA is not 
    proposing any changes to the first two sentences of current 
    Sec. 170.30(a), which reflect the language of the GRAS exemption as set 
    out in section 201(s) of the act.
        The final sentence of current Sec. 170.30(a) provides that general 
    recognition of safety requires that there be common knowledge about the 
    substance throughout the scientific community knowledgeable about the 
    safety of substances directly or indirectly added to food. FDA is 
    proposing to amend this provision to define what that common knowledge 
    is (i.e., that there is reasonable certainty that the substance is not 
    harmful under the intended conditions of use). In other words, proposed 
    Sec. 170.30(a) would clarify that the safety standard for a GRAS 
    substance is identical to the safety standard in Sec. 170.3(i) and that 
    a GRAS substance is neither more safe nor less safe than an approved 
    food additive. Rather, the distinction between a GRAS substance and an 
    approved food additive is that, for a GRAS substance, there is common 
    knowledge of safety within the expert community.
    
    B. Scientific Procedures GRAS Determination
    
    1. Establishing General Recognition of Safety
        Current Sec. 170.30(b) describes the technical element of a 
    scientific procedures GRAS determination (i.e., that it requires the 
    same quantity and quality of scientific evidence as is required to 
    obtain approval of the substance as a food additive). Current 
    Sec. 170.30(b) also describes the common knowledge element of a 
    scientific procedures GRAS determination (i.e., that it ordinarily is 
    based upon published studies, which may be corroborated by unpublished 
    studies and other data and information).
        FDA is proposing two changes to the description of the common 
    knowledge element in current Sec. 170.30(b). First, FDA is proposing to 
    broaden this description to clarify the types of technical evidence of 
    safety (currently described only as ``studies'') that could form the 
    basis of a GRAS determination. FDA is proposing this change because the 
    quantity and quality of scientific evidence required to obtain approval 
    of a substance as a food additive vary considerably depending upon the 
    estimated dietary exposure to the substance and the chemical, physical, 
    and physiological properties of the substance; there can likewise be a 
    comparable variation in the scientific evidence that forms the basis of 
    a GRAS determination. Second, FDA is proposing to amend this 
    description to clarify the role of publication in satisfying the common 
    knowledge element. FDA is proposing this change because publication is 
    ordinarily required, but may not always be sufficient, to satisfy the 
    common knowledge element of the GRAS standard.
        Specifically, FDA is proposing to revise Sec. 170.30(b) to provide 
    that general recognition of safety through scientific procedures be 
    based upon generally available and accepted scientific data, 
    information, methods, or principles, which ordinarily are published. 
    Thus, under proposed Sec. 170.30(b), ``studies'' would be one of 
    several types of scientific ``data and information'' that could support 
    the technical element of a scientific procedures GRAS determination. 
    However, depending on the circumstances, other scientific data and 
    scientific information such as that relating to chemical identity or 
    characteristic properties of a substance, as well as methods of 
    manufacture, could support, and in some cases be sufficient to satisfy 
    that element.
        In addition, under this proposed revision of Sec. 170.30(b), 
    generally available and accepted scientific principles could be applied 
    to, and relied on as part of, the technical element of a scientific 
    procedures GRAS determination. Webster's New World Dictionary of the 
    American Language defines a ``principle'' as ``a fundamental truth, 
    law, doctrine or motivating force upon which others are based.'' For 
    example, the common scientific principle ``the dose makes the poison,'' 
    underlies a determination that a substance is safe for use in food at 
    certain levels even if it exhibits toxicity when present at higher 
    levels. A related scientific principle is that the toxicity of a 
    substance may vary between animal species. FDA relies on both of these 
    scientific principles when determining whether the proposed use of a 
    substance added to food is safe within the meaning of section 409 of 
    the act.
        For consistency with this proposed amendment, FDA is also proposing 
    to amend the current definition of ``scientific procedures'' in 
    Sec. 170.3(h). Under the current definition, scientific procedures 
    include those human, animal, analytical, and other scientific studies, 
    whether published or unpublished, appropriate to establish the safety 
    of a substance. FDA is proposing to amend Sec. 170.3(h) by broadening 
    it so that scientific procedures would include scientific data (such as 
    human, animal, analytical, and other scientific studies), information, 
    methods, or principles, whether published or unpublished, appropriate 
    to establish the safety of a substance. In both this proposed 
    definition and the proposed amendment to Sec. 170.30(b), the descriptor 
    ``scientific'' applies equally to ``data,''
    
    [[Page 18943]]
    
    ``information,'' ``methods,'' and ``principles.''
        FDA is proposing to clarify the role of publication in satisfying 
    the common knowledge element of the GRAS standard by adding the phrases 
    ``generally available and accepted'' and ``which ordinarily are 
    published'' as descriptors of ``scientific data, information, methods, 
    or principles'' in proposed Sec. 170.30(b). Thus, under proposed 
    Sec. 170.30(b), publication of data and information about a GRAS 
    substance is usually necessary, but may not always be sufficient, to 
    satisfy the common knowledge element of the GRAS standard.
        The descriptor ``which ordinarily are published'' reflects that the 
    usual mechanism to establish that scientific information is generally 
    available is to show that the information is published in a peer-
    reviewed scientific journal. This descriptor maintains the explicit 
    emphasis of current Sec. 170.30(b) on the importance of publication in 
    satisfying the common knowledge element. However, current 
    Sec. 170.30(b) does not explicitly emphasize the second facet of the 
    common knowledge element (i.e., that there is a basis to conclude that 
    there is the requisite expert consensus that the generally available 
    data and information establish the safety of the substance for its 
    intended use). For example, there could be a basis to conclude that 
    there is expert consensus that the published results of a particular 
    safety study (i.e., the primary scientific literature) establish the 
    safety of a substance for its intended use if the study raises no 
    safety questions that experts would need to interpret and resolve. On 
    the other hand, the published results of a particular safety study may 
    not be sufficient to satisfy the common knowledge element if the study 
    raises safety questions that require additional data to be resolved. In 
    such cases, the general recognition standard usually requires more than 
    a publication in the primary scientific literature. As mentioned, the 
    basis for concluding that there is expert consensus historically has 
    included publication in secondary sources, convening an expert panel, 
    or relying on an opinion or recommendation of an authoritative body.
        The body of information published in secondary sources (such as 
    review articles, articles describing scientific methods, general 
    reference materials, and textbooks) can be more useful than the primary 
    scientific literature for showing a basis for a conclusion that the 
    necessary expert consensus exists because the existence of the 
    secondary sources implies that the primary scientific literature has 
    been evaluated after its publication. For example, FDA sometimes relies 
    on generally available and accepted compendia such as Bergey's Manual 
    of Systematic Bacteriology (Ref. 4) when evaluating the common 
    knowledge element of the GRAS standard for food substances derived from 
    a bacterial source.
        The opinion of a specially-convened expert panel can provide a 
    basis for showing expert consensus when an individual published study 
    raises safety questions. The opinion of an expert panel is also useful 
    when multiple studies bearing on the safety of a substance are 
    published but there are no secondary sources that evaluate these 
    studies and draw general conclusions based on this comprehensive body 
    of knowledge. For example, during the agency-initiated GRAS review, FDA 
    commissioned, through the Life Sciences Research Office of the 
    Federation of American Societies for Experimental Biology, the ``Select 
    Committee on GRAS Substances'' (the Select Committee). The charge to 
    the Select Committee was to summarize the available scientific 
    literature and to provide a recommendation as to what restrictions, if 
    any, on the use of the substance would be needed to ensure its safe use 
    in food.
        In FDA's view, the common knowledge element of the GRAS standard 
    precludes a GRAS determination if the data and information evaluated by 
    such an expert panel are only available in files that are not publicly 
    accessible, such as in confidential industry files. For example, in 
    response to GRAS petitions requesting that FDA affirm the GRAS status 
    of lactase from Kluyveromyces lactis entrapped in cellulose triacetate 
    fibers for use in reducing the lactose content of milk, FDA affirmed 
    that the lactase enzyme was GRAS (49 FR 47384, December 4, 1984) but 
    issued a food additive regulation authorizing the secondary direct food 
    additive use of cellulose triacetate as an immobilizing agent because 
    the information that the petitioner relied on to establish the safety 
    of the cellulose triacetate was not generally available (59 FR 36935, 
    July 20, 1994).
        The opinions or recommendations of an authoritative body such as 
    NAS or CON/AAP frequently bear on an issue that is related to a GRAS 
    determination. For example, CON/AAP may recommend the use in infant 
    formula of a food substance whose regulatory status is not explicitly 
    identified in FDA's regulations. Similarly, NAS's Recommended Dietary 
    Allowances (Ref. 5) are useful in establishing the safe level of an 
    added nutrient source in foods, particularly when the safe level of 
    intake is a narrow range because the difference between the recommended 
    dietary intake and the intake at which the substance exhibits toxic 
    properties is small. In cases such as these, the opinions or 
    recommendations of the authoritative body may provide a basis for 
    concluding that there is expert consensus regarding the safety of a 
    substance for its intended use in food.
    2. Corroboration of Safety
        FDA is proposing to retain the concept in current Sec. 170.30(b) 
    that unpublished data and information that bear on safety may be used 
    to corroborate published data and information that establish general 
    recognition of safety. FDA is proposing to amend current Sec. 170.30(b) 
    by removing the phrase ``unpublished studies and other data and 
    information'' and substituting the phrase ``unpublished scientific 
    data, information, or methods.'' This proposed revision is comparable 
    to the proposed broadening of the description of the common knowledge 
    element of the GRAS standard and likewise reflects the variation in the 
    nature of the scientific evidence that would be required to obtain 
    approval of the substance as a food additive.
    
    C. Common Use GRAS Determination
    
        FDA is not proposing any changes to current Sec. 170.30(c)(1), 
    which sets out criteria for a common use GRAS determination. However, 
    FDA is proposing to amend current Sec. 170.30(c)(2), which sets out 
    these criteria in the more narrow circumstance of that use occurring 
    exclusively or primarily outside of the United States. FDA is proposing 
    to revise the final sentence of current Sec. 170.30(c)(2) by replacing 
    the recommendation that persons who claim GRAS status on such basis 
    obtain FDA concurrence that the use of the substance is GRAS (i.e., 
    through submission of a GRAS affirmation petition) with a 
    recommendation that persons who assert such a claim for a substance 
    notify FDA of that claim in accordance with proposed Sec. 170.36. This 
    revision is a necessary conforming amendment because, as discussed in 
    sections V and VI of this document, FDA is proposing to replace the 
    current affirmation process in Sec. 170.35(c)(1) with a notification 
    procedure (proposed Sec. 170.36). The recommendation in proposed 
    Sec. 170.30(c)(2) is appropriate because notice will facilitate the 
    lawful entry of GRAS substances into the United States. FDA will be 
    aware that a
    
    [[Page 18944]]
    
    substance offered for import is the subject of a GRAS exemption claim 
    and will also be aware of the basis for such claim. Absent notice, the 
    substance may appear to be adulterated and thus, be detained under 
    section 801(a) of the act (21 U.S.C. 381(a)). Therefore, it is prudent 
    for an individual who claims that a substance is GRAS through 
    experience based on its common use in food outside of the United States 
    to notify FDA of that claim. The language of proposed Sec. 170.30(c)(2) 
    is comparable to the language of current Sec. 170.30(c)(2) in that it 
    is not a requirement.
    
    D. Other Provisions of Current Sec. 170.30
    
        FDA is not proposing any changes to the remainder of current 
    Sec. 170.30, except Sec. 170.30(f) as discussed below, because the 
    changes that the agency is proposing in this document require no 
    conforming amendments to those sections.
        Current Sec. 170.30(f) was issued under the auspices of the agency-
    initiated GRAS review (36 FR 12093, June 25, 1971) and expresses the 
    agency's intent to review the GRAS status of certain food substances. 
    As discussed in section V of this document), FDA is proposing to remove 
    the provision in Sec. 170.35(a) that the Commissioner of Food and Drugs 
    (the Commissioner), on the petition of an interested person, may affirm 
    the GRAS status of substances that directly or indirectly become 
    components of food. The agency is proposing to retain, however, the 
    provision in Sec. 170.35(a) that the Commissioner, on his/her own 
    initiative, may affirm the GRAS status of such substances. In addition, 
    the agency is proposing no changes to the provision in Sec. 170.35(b) 
    that if the Commissioner concludes that there is a lack of convincing 
    evidence that a substance is GRAS and that it should be considered a 
    food additive, he/she shall publish a notice thereof in the Federal 
    Register in accordance with Sec. 170.38. Therefore, Sec. 170.30(f) is 
    redundant with Sec. 170.35 (a) and (b). Accordingly, in keeping with 
    the agency's goals for the Reinventing Food Regulations, FDA is 
    proposing to remove current Sec. 170.30(f).
    
    IV. The Technical Element of a GRAS Determination Through Scientific 
    Procedures
    
        A GRAS substance is distinguished from a food additive on the basis 
    of the common knowledge about the safety of the substance for its 
    intended use rather than on the basis of what the substance is or the 
    types of data and information that are necessary to establish its 
    safety. Nonetheless, FDA is frequently asked about the types of data 
    and information that are appropriate to establish the safety of a GRAS 
    substance. Accordingly, FDA discusses below two topics that pertain to 
    the technical element of a scientific procedures GRAS determination: 
    (1) The importance of dietary exposure; and (2) the role of substantial 
    equivalence.
    
    A. Consideration of Dietary Exposure
    
        Section 409(c)(5) of the act requires that, in evaluating the 
    proposed use of a food additive, FDA consider the probable consumption 
    of the substance and of any substance formed in or on food because of 
    its use, as well as the cumulative effect of the substance in the diet, 
    taking into account any chemically or pharmacologically related 
    substance or substances in such diet. FDA has incorporated this 
    requirement into the definition of ``safe'' and ``safety'' with respect 
    to substances added to food (Sec. 170.3(i)). Thus, the technical 
    element of a scientific procedures GRAS determination must consider the 
    probable consumption and cumulative effect of the substance in the diet 
    because a scientific procedures GRAS determination requires the same 
    quantity and quality of evidence as is required to obtain approval of 
    the substance as a food additive. If the dietary exposure to the 
    substance under the intended conditions of use presents a basis for 
    concern about the safety of its use, data or information addressing 
    those concerns are necessary to satisfy the technical element. As with 
    other data and information that support a GRAS determination, data or 
    information addressing a safety question raised by dietary exposure 
    must also satisfy the common knowledge element by being generally 
    available to, and accepted by, qualified experts.
        In some cases, dietary exposure is unlikely to present a basis for 
    a safety concern. For example, dietary exposure to an enzyme 
    preparation that is derived from a controlled fermentation of a 
    nonpathogenic, nontoxigenic microorganism that does not produce 
    antibiotics, and that is processed using substances that are acceptable 
    for use in foods generally, would not ordinarily present a basis for a 
    safety concern. On the other hand, consumption of a component of a 
    commonly consumed food may present a basis for a safety concern if the 
    dietary exposure to the isolated component under its intended 
    conditions of use is many times greater than its dietary exposure when 
    consumed as a component of food.
        For example, a fiber may be extracted from a vegetable that has a 
    relatively low dietary exposure (such as beets) and added, at the same 
    level, to other foods that have a relatively high dietary exposure. The 
    probable cumulative intake of the fiber likely will be many times 
    higher from the consumption of the foods to which it is added than from 
    the consumption of beets. The probable intake of the fiber from 
    consumption of foods to which it is added may present a basis for a 
    safety concern, especially if the foods containing the added beet fiber 
    will not replace beets in the diet. Likewise, in the case of a 
    chemically synthesized substance that is structurally identical to a 
    naturally occurring substance in commonly consumed food, technical 
    evidence of safety would include consideration of whether the 
    cumulative exposure to both the synthetic and the natural substance 
    exceeds the exposure to the natural substance and whether the combined 
    exposure presents a basis for a safety concern.
    
    B. Substantial Equivalence to a GRAS Substance
    
        A report of a joint Food and Agriculture Organization (FAO) and 
    World Health Organization (WHO) consultation (the 1996 FAO/WHO report) 
    recommended that ``[s]afety assessment based on the concept of 
    substantial equivalence * * * be applied in establishing the safety of 
    foods and food components derived from genetically modified organisms'' 
    (Ref. 6). The 1996 FAO/WHO report stated that:
    
    [s]ubstantial equivalence embodies the concept that if a new food or 
    food component is found to be substantially equivalent to an 
    existing food or food component, it can be treated in the same 
    manner with respect to safety (i.e. the food or food component can 
    be concluded to be as safe as the conventional food or food 
    component). Account should be taken of any processing that the food 
    or food component may undergo as well as the intended use and the 
    intake by the population.
    
    The 1996 FAO/WHO report relied, in part, on previous expert reports 
    that had discussed the concept of substantial equivalence, including 
    the 1990 joint FAO/WHO consultation, ``[s]trategies for assessing the 
    safety of foods produced by biotechnology'' (Ref. 7); a report prepared 
    by an expert group of the Organization for Economic Co-operation and 
    Development (OECD), ``[s]afety evaluation of foods produced by modern 
    biotechnology: Concepts and principles'' (Ref. 8); and a report of a 
    WHO workshop, ``[a]pplication of the principles of substantial 
    equivalence to the safety evaluation of foods or food components from 
    plants derived by modern biotechnology'' (Ref. 9).
    
    [[Page 18945]]
    
        FDA believes that in certain instances the concept of substantial 
    equivalence may have applicability to the technical element of a GRAS 
    determination, and the agency has already applied this concept when 
    evaluating the safety of new or modified food substances. For example, 
    the agency's approach (57 FR 22984 and Ref. 10) to assessing the safety 
    of foods derived from new plant varieties, including the safety of 
    newly introduced substances in the food (primarily proteins, 
    carbohydrates, and fatty acids) and unintended changes in the food's 
    composition, is similar to the concept of substantial equivalence 
    posited by FAO, WHO, and OECD. 2 As another example, FDA has 
    applied this concept in affirming the GRAS status of several 
    microbially-derived chymosin (i.e., rennet) enzyme preparations (55 FR 
    10932 at 10935, March 23, 1990; 57 FR 6476 at 6479, February 25, 1992; 
    58 FR 27197 at 27202, May 7, 1993) and several animal-and plant-derived 
    enzyme preparations (60 FR 32904 at 32911, June 26, 1995).
    ---------------------------------------------------------------------------
    
        \2\ In the plant policy statement, FDA used the term 
    ``substantial similarity,'' rather than ``substantial equivalence,'' 
    to avoid possible confusion with the agency's use of the concept of 
    ``substantial equivalence'' with respect to the premarket 
    notification process for medical devices. For consistency with 
    current thinking from international expert groups such as the FAO/
    WHO and OECD consultation groups, FDA is now using the term 
    ``substantial equivalence'' with respect to food products.
    ---------------------------------------------------------------------------
    
        However, the concept of substantial equivalence may be of minimal 
    relevance in circumstances where the differences between two substances 
    outweigh the similarities. Thus, a critical factor that must be 
    considered when applying the concept of substantial equivalence is any 
    difference in composition or characteristic properties between the 
    substances being compared. In the example of a microbially-derived 
    enzyme preparation, its principal enzyme component may show substantial 
    equivalence in structure and function to that of a GRAS enzyme 
    preparation derived from an animal source but exhibit different 
    properties such as specific activity (i.e., the rate at which the 
    enzyme catalyzes a reaction) or optimum reaction conditions of pH and 
    temperature because of changes, either through natural selection or 
    through selective chemical modification, in the particular amino acid 
    sequence of the enzyme's active site. Such differences, which are 
    common when comparing enzyme preparations derived from different 
    sources, generally do not outweigh the similarities between the enzyme 
    preparations.
        On the other hand, the product resulting from the chemical reaction 
    of two or more GRAS substances is a discrete new substance that may 
    have properties that are distinctly different from the individual GRAS 
    substances from which it is synthesized or from a simple mixture of 
    those GRAS substances. The concept of substantial equivalence may not 
    be relevant here unless the reaction product is widely recognized to be 
    metabolized in the same way as the individual components from which it 
    is synthesized. Likewise, in the case of a chemically synthesized 
    substance that is structurally identical to a naturally occurring 
    substance in commonly consumed food, compositional differences between 
    the synthesized and naturally occurring substance may include the 
    presence of any residues of potentially harmful chemicals carried over 
    to the synthetic substance from the manufacturing process.
        FDA invites comment on the applicability of the concept of 
    substantial equivalence to the technical element of a GRAS 
    determination.
    
    V. Proposed Revisions to Sec. 170.35--Affirmation of GRAS Status
    
        As a result of the agency's experience in processing FAP's and GRAS 
    affirmation petitions, FDA has tentatively concluded that the petition 
    process, which is the statutorily mandated process for food additives, 
    should no longer be applied to GRAS substances, where the conditions of 
    safe use of a substance have already been recognized by qualified 
    experts. FDA believes that the lengthy rulemaking associated with the 
    GRAS petition process deters many persons who independently determine 
    that use of a substance is GRAS from informing the agency of such 
    determinations. Moreover, FDA believes that the current commitment of 
    its resources to the GRAS petition process provides limited public 
    health benefit because manufacturers who submit an affirmation petition 
    frequently market the substance at issue before FDA reaches a decision 
    on the GRAS status of its intended use.
        Accordingly, FDA is proposing to amend current Sec. 170.35(a) to 
    remove the provision that FDA may review the GRAS status of a substance 
    added to food in response to a petition from an interested party. FDA 
    has tentatively concluded that the elimination of the GRAS petition 
    process would not adversely affect public health because the agency is 
    simultaneously proposing to establish a notification procedure for GRAS 
    substances. FDA has also tentatively concluded that the proposed 
    notification procedure, discussed more fully in section VI of this 
    document, would allow the agency to direct its resources to the more 
    significant questions about GRAS status.
        Proposed Sec. 170.35(a) would continue to provide a mechanism 
    whereby FDA, on its own initiative, may affirm the GRAS status of the 
    use of a substance that directly or indirectly becomes a component of 
    food. FDA proposes to retain the option of agency-initiated 
    affirmations for those circumstances where such action is necessary or 
    useful. For example, FDA may propose to revise an existing regulation 
    affirming the GRAS status of a use of a substance if the agency 
    determines that the current regulation is confusing or unnecessarily 
    restrictive. In addition, the agency may choose to complete a 
    rulemaking already begun as part of the agency-initiated GRAS review.
        Proposed Sec. 170.35(a) includes a technical revision that amends 
    current Sec. 170.35(a) to place it in the singular. For consistency 
    with the language of the statute, proposed Sec. 170.35(a) also has been 
    revised to clarify that the Commissioner might affirm the GRAS status 
    of a use of a substance, rather than the substance itself.
        In light of the increasing complexity of the food supply, FDA 
    recognizes that members of the food industry may wish to engage in 
    discussions with the agency concerning novel issues that accompany the 
    technical element of some GRAS determinations. FDA believes that the 
    elimination of the GRAS petition process will not constrain industry 
    from consulting with the agency about such novel issues. Rather, FDA 
    believes that the substitution of the proposed notification procedure 
    for the current petition process will encourage industry to consult 
    with FDA early in development of food substances to identify the 
    critical aspects of the safety determination that would need general 
    recognition to qualify for a GRAS exemption.
        FDA is also proposing to remove current Sec. 170.35(c), which 
    prescribes the procedure for the submission of a GRAS affirmation 
    petition. Under proposed Sec. 170.35(a), FDA will no longer be bound to 
    review such a petition. Therefore, if proposed Sec. 170.35(a) becomes 
    final, current Sec. 170.35(c) will become obsolete.
    
    VI. Proposed Establishment of a Notification Procedure
    
    A. General Requirements
    
        Proposed Sec. 170.36(a)(1) provides that any person may notify FDA 
    of a claim
    
    [[Page 18946]]
    
    that a particular use of a substance is exempt from the statutory 
    premarket approval requirements based on the notifier's determination 
    that such use is GRAS. The agency encourages manufacturers and 
    developers of food substances and of new processes for producing food 
    substances to use this notification procedure to inform FDA if such 
    manufacturers or developers conclude that there is general recognition 
    that use of a substance is safe.\3\
    ---------------------------------------------------------------------------
    
        \3\ FDA considers that the current voluntary procedure whereby 
    developers of new plant varieties modified through the use of rDNA 
    techniques notify the agency about food derived from the plant is 
    parallel to, and has some overlapping provisions with, the proposed 
    GRAS notification procedure but is nonetheless distinct from this 
    proposed procedure. For example, current notices to the agency 
    concerning new plant varieties generally are broader in scope than 
    the regulatory status of substances introduced into the new plant 
    variety and usually include a safety and nutritional assessment of 
    food derived from the new plant variety in addition to a basis for 
    the notifier's determination that an FAP is not required for any of 
    the substances introduced into that food.
    ---------------------------------------------------------------------------
    
        Current agency regulations concerning the eligibility of a 
    substance for a health claim (Sec. 101.14(b)(3)(ii)) (21 CFR 
    101.14(b)(3)(ii)) require that a substance that is to be consumed as a 
    component of conventional food at other than decreased dietary levels 
    be a food, food ingredient, or a component of a food ingredient, whose 
    use, at the levels necessary to justify a claim, be demonstrated by the 
    proponent of the claim, to FDA's satisfaction, to be safe and lawful 
    under the applicable food safety provisions of the act. In the final 
    rule establishing Sec. 101.14(b)(3)(ii) (58 FR 2478 at 2502, January 6, 
    1993), FDA explained that the preliminary requirement that a substance 
    be safe and lawful was necessary in the health claim regulation because 
    FDA's authorization of a health claim places the agency's imprimatur on 
    the claim. FDA further stated that it would be a violation of the 
    agency's responsibility under the act to authorize a health claim for a 
    substance without the agency being satisfied that the particular use of 
    the substance is safe. As discussed in detail in section VI.D of this 
    document, an agency response to a GRAS notice would not be equivalent 
    to an agency affirmation of GRAS status. Therefore, if adopted, the 
    GRAS notification procedure proposed in this notice will not satisfy a 
    health claim petitioner's responsibilities under Sec. 101.14(b)(3)(ii).
        In addition, FDA recently proposed that good manufacturing practice 
    for infant formula requires that only substances whose use in infant 
    formula is safe and suitable under the applicable food safety 
    provisions of the act be used to make this product; that is, that the 
    substance be GRAS for such use, used in accordance with the agency's 
    food additive regulations, or authorized for such use by a prior 
    sanction (proposed Sec. 106.40(a); 61 FR 36154 at 36212, July 9, 1996). 
    FDA also proposed that a ``new infant formula'' submission required 
    under section 412 (c) and (d) of the act (21 U.S.C. 350a (c) and (d)) 
    include the basis on which each ingredient meets the requirements of 
    proposed Sec. 106.40(a), and that any claim that an ingredient is GRAS 
    be supported by a citation to the agency's regulations or by an 
    explanation as to why there is general recognition of the safety of the 
    use of the ingredient in infant formula (proposed 
    Sec. 106.120(b)(6)(ii); 61 FR 36154 at 36217). Again, as discussed in 
    detail in section VI.D of this document, an agency response to a GRAS 
    notice would not be equivalent to an agency affirmation of GRAS status 
    or place an agency imprimatur on the substance that is the subject of 
    the notice. Therefore, if adopted, this proposed GRAS notification 
    program will not substitute for the requirements proposed for new 
    infant formula submissions.
        The fact that the proposed GRAS notification program will not 
    satisfy the requirements of either Sec. 101.14(b)(3)(ii) or proposed 
    Sec. 106.120(b)(6)(ii) is reflected in proposed Sec. 170.36(a)(2). 
    Under proposed Sec. 170.36(a)(2)(i), any person who submits a health 
    claim petition under Sec. 101.14 must comply in full with 
    Sec. 101.14(b)(3)(ii), regardless of whether the agency has been 
    notified under proposed Sec. 170.36 about a relevant GRAS determination 
    and regardless of the nature of the agency's response to that notice. 
    Similarly, proposed Sec. 170.36(a)(2)(ii) provides that any person who 
    makes a new infant formula submission under Sec. 106.120 must comply in 
    full with Sec. 106.120(b)(6)(ii), regardless of whether the agency has 
    been notified under proposed Sec. 170.36 about a relevant GRAS 
    determination and regardless of the nature of the agency's response to 
    that notice.
        Proposed Sec. 170.36(b) requires that notice of a GRAS exemption 
    claim be submitted in triplicate and provides the address for such a 
    submission. FDA plans to use one copy of the notice for the agency's 
    administrative record. FDA anticipates that at least two agency 
    scientists, with food safety expertise relating to identity, dietary 
    exposure and health effects, will evaluate most notices. Thus, for 
    efficient administration of the notification procedure, FDA is 
    stipulating that three copies of a notice be submitted.
        FDA is aware that there is increasing interest in submitting an 
    electronic copy of information prepared for regulatory purposes. FDA 
    requests comment on whether it would be appropriate to require or 
    recommend that the submission include an electronic copy in addition to 
    the three paper copies required under proposed Sec. 170.36(b).
    
    B. Specific Requirements
    
        Proposed Sec. 170.36(c) provides details on information that must 
    be included in a notice. FDA recognizes that a decision to submit a 
    notice is voluntary. However, as discussed (see discussion of proposed 
    Sec. 170.36(e)), under the proposed notification procedure, FDA would 
    respond to a notice within 90 days. In order for the agency to meet 
    this timeframe, the information in the notice needs to be presented in 
    an orderly and consistent fashion. Moreover, FDA believes that a 
    prescribed format and a description of information that the agency 
    considers important in supporting a GRAS determination would simplify 
    the notifier's task of preparing the notice.
    1. GRAS Exemption Claim
        A GRAS determination must comply with the provisions of Sec. 170.30 
    and the person making such determination is responsible for ensuring 
    such compliance, regardless of whether that person notifies the agency 
    about the determination. Accordingly, proposed Sec. 170.36(c)(1) 
    requires that the notice include a claim (hereinafter referred to as 
    the ``GRAS exemption claim''), dated and signed by the notifier, that a 
    particular use of a substance is exempt from the premarket approval 
    requirements of the act because the notifier has determined that such 
    use is GRAS. Proposed Sec. 170.36(c)(1) would distinguish the 
    notification procedure, in which the notifier explicitly accepts 
    responsibility for the GRAS determination, from the GRAS petition 
    process, in which the notifier is requesting that the agency affirm the 
    GRAS status of use of a substance.
        Proposed Sec. 170.36 (c)(1)(i) through (c)(1)(iv) identify specific 
    information required in a GRAS exemption claim in a prescribed format. 
    This requirement will simplify the notifier's task of preparing this 
    section of a notice and will enable the agency to use this section of a 
    notice to effectively and efficiently inform the public about received 
    notices (see discussion of proposed Sec. 170.36(f)(2)).
        FDA has requested comment on whether proposed Sec. 170.36(b) should 
    require or recommend that an electronic copy of the entire notice be 
    submitted
    
    [[Page 18947]]
    
    in addition to three paper copies. In particular, receiving electronic 
    copies of the GRAS exemption claim may make FDA's administration of the 
    GRAS notification procedure more efficient, especially if the agency 
    uses an electronic means to make those claims readily accessible to the 
    public. Accordingly, FDA specifically requests comment on whether the 
    regulation should include a recommendation or requirement that the 
    notice include an electronic copy of the GRAS exemption claim required 
    by proposed Sec. 170.36(c)(1).
        a. Notifier. Proposed Sec. 170.36(c)(1)(i) requires that the GRAS 
    exemption claim include the name and address of the notifier. This is 
    necessary for full identification of the person who accepts 
    responsibility for the claim. This is also necessary so that the agency 
    can both acknowledge receipt of the notice (proposed Sec. 170.36(d)) 
    and inform the notifier of the agency's response to the notice 
    (proposed Sec. 170.36(e)).
        b. Name of notified substance. Proposed Sec. 170.36(c)(1)(ii) 
    requires that the GRAS exemption claim include the common or usual name 
    of the notified substance. This is necessary to identify the notified 
    substance as well as to identify whether there are any labeling issues 
    that need to be addressed. The notifier may include in the GRAS 
    exemption claim additional information, such as that described in 
    proposed Sec. 170.36(c)(2), concerning the identity of the substance if 
    such information is appropriate or necessary to fully and unambiguously 
    describe it.
        The agency recognizes that notifiers may have questions concerning 
    the common or usual name for a notified substance. FDA advises that in 
    such circumstances, a notifier should consult with the Office of Food 
    Labeling in FDA's Center for Food Safety and Applied Nutrition (CFSAN).
        c. Conditions of use. Proposed Sec. 170.36(c)(1)(iii) requires that 
    the GRAS exemption claim identify the applicable conditions of use of 
    the notified substance, including the foods in which the substance is 
    to be used, levels of use in such foods, and the purposes for which the 
    substance is used, including, when appropriate, a description of the 
    population expected to consume the substance (e.g., if the substance is 
    intended for use in a limited population, such as ingredients used 
    mainly in infant formula, medical foods, or in specially designed food 
    products typically consumed as a sole source of the diet by persons who 
    are unable to consume food in conventional form). Information 
    describing the conditions of use is necessary to delineate the 
    boundaries of the GRAS exemption claim consistent with section 201(s) 
    of the act, which states that a GRAS substance must be generally 
    recognized as safe ``under the conditions of its intended use.'' This 
    information is also necessary to determine whether dietary exposure to 
    the substance presents a basis for concern about the safety of its use.
        d. Basis for the GRAS determination. Proposed Sec. 170.36(c)(1)(iv) 
    requires that the GRAS exemption claim identify the basis for the GRAS 
    determination as either scientific procedures or experience based on 
    common use in food. The act differentiates between these two bases for 
    GRAS determination and, under Sec. 170.30, the requirements for a 
    scientific procedures GRAS determination are different from the 
    requirements for a common use GRAS determination. The basis for a GRAS 
    determination is thus fundamental to the GRAS exemption claim.
        e. Availability of information. A GRAS determination must comply 
    with the provisions of Sec. 170.30 and the person making such 
    determination is responsible for ensuring such compliance, regardless 
    of whether that person notifies the agency about the determination. As 
    discussed more fully below (see discussion of proposed 
    Sec. 170.36(c)(4)), and in keeping with the agency's commitment to 
    achieving the goals for Reinventing Food Regulations, FDA is proposing 
    to require that a notifier supply a detailed summary of the information 
    that is the basis for a GRAS determination rather than the information 
    itself. Proposed Sec. 170.36(c)(1)(v) provides a mechanism for FDA to 
    verify the information that supports a GRAS determination by requiring 
    that the GRAS exemption claim include a statement that the data and 
    information that are the basis for the determination are available for 
    review and copying by FDA or will be sent to FDA upon request. 
    Notifiers who voluntarily choose to notify FDA of a GRAS determination 
    receive as a benefit a response that documents the agency's awareness 
    of the determination. As a condition of that benefit, the notifier must 
    consent to grant FDA access to the data and information that are the 
    basis of the GRAS determination.
        There is no burden on the notifier for developing the data and 
    information that are the basis for the GRAS determination because such 
    data and information must already be generally available in order to 
    satisfy the common knowledge element of a GRAS determination. 
    Additionally, any person who determines that a substance is GRAS should 
    have assembled and evaluated the evidence that forms the basis of such 
    a determination, regardless of whether the person subsequently notifies 
    the agency about the claim. Therefore, FDA believes that the burden to 
    the notifier of the proposed rule is the minimal burden of maintaining 
    the information. Such preservation of the data and information that are 
    the basis for the GRAS determination also represents prudent practice 
    for those who claim an exemption from a statutory requirement.
        The new procedure that FDA is proposing to establish will involve 
    the submission of a detailed summary of the information that forms the 
    basis for an exemption from a statutory requirement rather than the 
    submission of the information itself. It therefore is prudent that FDA 
    monitor compliance with the essence of the statutory requirement (i.e., 
    that there is common knowledge among qualified experts that there is 
    reasonable certainty that the substance is not harmful under the 
    intended conditions of use). Accordingly, FDA intends to conduct random 
    audits of data and information maintained by the notifier. Moreover, 
    because the proposed substitution of a notification procedure for the 
    current petition process would allow FDA to direct its resources to 
    priority questions about GRAS status, FDA might conduct an audit on a 
    broad issue or class of products if the issue or use of a class of 
    products raises important public health issues.
    2. Identity and Specifications
        Proposed Sec. 170.36(c)(2) requires that the notice include 
    detailed information about the identity of the notified substance, 
    including, as applicable, the chemical name, Chemical Abstracts Service 
    (CAS) registry number, Enzyme Commission (EC) number, empirical 
    formula, structural formula, quantitative composition, method of 
    manufacture (excluding any trade secret information), characteristic 
    properties, any potential human toxicants, and specifications for food-
    grade material. This detailed information, which would be in addition 
    to the substance's common or usual name that would be included under 
    proposed Sec. 170.36(c)(1)(ii), is necessary to describe accurately the 
    notified substance using commonly accepted scientific nomenclature and 
    practice.
        For some substances, such as calcium acetate (21 CFR 184.1185), the 
    most relevant information concerning identity may be chemical 
    information such as its CAS registry number and empirical formula. For 
    other substances, such as whey (21 CFR 184.1979), a
    
    [[Page 18948]]
    
    chemical formula cannot be used for identification; instead, source and 
    quantitative composition (e.g., percent of protein, fat, ash, lactose, 
    and moisture) appropriately describe the substance.
        In many cases, the method of manufacture provides important 
    identity information. For example, an enzyme preparation that is 
    derived from an animal source and contains the enzyme chymosin as its 
    principal enzyme component (Sec. 184.1685(a)(1) (21 CFR 
    184.1685(a)(1))) is chemically different from an enzyme preparation 
    that is derived from a microbial source and contains the enzyme 
    chymosin as its principal enzyme component (Sec. 184.1685(a)(2)) 
    because the components and contaminants derived from the source 
    material are distinctly different.
        In some cases, the characteristic properties of a substance may be 
    important when defining the conditions under which the substance may 
    safely be used. For example, if an isolated or chemically processed 
    fiber is intended for use as a replacement for part of the flour used 
    in baked goods, information about its physicochemical properties, such 
    as its ability to swell due to high water absorption or to bind 
    physiologically important ions, may be important in establishing a safe 
    level of the fiber in baked goods.
        The proposed requirement that information relating to identity 
    include any potential human toxicants in the notified substance derives 
    from the known presence of such toxicants in substances of natural 
    biological origin. For example, it is well known that potatoes contain 
    the naturally occurring toxicant, solanine. In the plant policy 
    statement (57 FR 22984 at 22987), FDA discussed the importance of 
    ensuring that new plant varieties do not contain significantly higher 
    levels of toxicants than are present in other edible varieties of the 
    same species. This consideration applies to all food products that 
    derive from a source known to contain naturally occurring toxicants.
        Specifications are an important factor in establishing food-grade 
    quality for any substance intended for use in food. Substances that do 
    not meet the specifications may not be suitable for use in food. 
    Specifications may be general or particular and may relate to identity, 
    purity, or both.
        General specifications governing both identity and purity are 
    common for GRAS substances. For example, the regulations for 
    microbially-derived GRAS substances usually stipulate, as a general 
    identity specification, that the source microorganism be a 
    nontoxigenic, nonpathogenic strain. Similarly, the regulations for many 
    GRAS substances stipulate, as a general purity specification, the 
    maximum permissible level of a heavy metal toxicant such as lead.
        In addition, GRAS substances frequently require a particular 
    identity specification to adequately define the substance whose safety 
    is generally recognized. For example, in affirming that canola oil 
    (i.e., low erucic acid rapeseed oil) is GRAS for use as an edible fat 
    and oil, FDA only considered the GRAS status of oil that contains 
    levels of a specific fatty acid (erucic acid) that are no more than 2 
    percent of the component fatty acids. Therefore, the identity 
    specification for low erucic acid rapeseed oil (21 CFR 184.1555(c)(1)) 
    stipulates that, chemically, the oil is a mixture of triglycerides, 
    composed of both saturated and unsaturated fatty acids, with an erucic 
    acid content of no more than 2 percent of the component fatty acids.
        In some cases, FDA expects that the specifications for a notified 
    substance may be generally available in a standard reference such as 
    the Food Chemicals Codex (FCC), which contains general and specific 
    requirements for more than 900 substances used in food. In other cases, 
    the specifications for the notified substance may be the same as, or 
    similar to, specifications in the agency's GRAS regulations but not 
    available in any other standard reference. For example, the 
    specifications for an oil that is substantially similar to hydrogenated 
    and partially hydrogenated menhaden oil, which FDA has affirmed as GRAS 
    for use as an edible fat or oil, could be based on the specifications 
    in 21 CFR 184.1472.
    3. Self-limiting Levels of Use
        Proposed Sec. 170.36(c)(3) requires that the notice include any 
    self-limiting levels of use of the substance. If a substance is added 
    to food above its technologically self-limiting level, the food becomes 
    unpalatable, unappealing or otherwise unfit for consumption. 
    Information on a technologically self-limiting level of use of a 
    substance would be important in addressing concerns about the level of 
    use of the substance as a food component. For example, it is generally 
    known that the taste associated with many GRAS synthetic flavoring 
    substances limits the levels at which the flavoring substances can be 
    used to levels below those known to exhibit toxic properties.
    4. Scientific Procedures GRAS Determination
        The technical element of a scientific procedures GRAS determination 
    requires that information about the substance show that there is 
    reasonable certainty in the minds of competent scientists that the 
    substance is not harmful under the intended conditions of use. The 
    nature of the information that the notifier relies on to establish the 
    technical element of the GRAS standard may vary from substance to 
    substance. Such information may include, but is not limited to, the 
    identity, characteristic properties, and methods of manufacture of the 
    notified substance, applicable toxicological studies, and information 
    relating to dietary exposure.
        The common knowledge element requires both that the information 
    relied on be generally available and that there be a basis to conclude 
    that there is expert consensus about the safety of the substance for 
    its intended use. A notice summary that fully describes the technical 
    evidence of safety, but does not provide a basis to conclude that the 
    technical evidence is generally available and accepted, would be 
    incomplete. The common knowledge element applies to all of the evidence 
    that is the basis for the safety determination.
        a. Technical evidence of safety. Proposed Sec. 170.36(c)(4)(i)(A) 
    requires that the notice include a detailed summary of the basis for 
    the notifier's determination that a particular use of the substance is 
    GRAS through scientific procedures. This summary would include a 
    comprehensive discussion of, and citations to, generally available and 
    accepted scientific data, information, methods, or principles that the 
    notifier relies on to establish safety.
        Proposed Sec. 170.36 (c)(2) and (c)(3) of the notice would require 
    that information relating to the identity, characteristic properties, 
    and methods of manufacture of the notified substance be described in 
    detail; therefore, the comprehensive discussion in the notice summary 
    should focus on how that information is relevant to the GRAS 
    determination. Under proposed Sec. 170.36(c)(4), the comprehensive 
    discussion in the notice summary of any applicable toxicological 
    studies should fully describe such studies, identify the conclusions 
    drawn from such studies, and explain how these conclusions are relevant 
    to the GRAS determination. FDA is not proposing to require that the 
    notice include the raw data supporting the conclusions of applicable 
    toxicological studies because the agency does not intend, in most 
    cases, to conduct its own detailed evaluation of those data.
    
    [[Page 18949]]
    
        Proposed Sec. 170.36(c)(4)(i)(A) specifies that the discussion in 
    the notice summary include a consideration of the probable consumption 
    of the substance and the cumulative effect of the substance in the 
    diet, taking into account any chemically or pharmacologically related 
    substances in such diet. This consideration of dietary exposure is 
    mandated for food additives by section 409(c)(5) of the act; 
    Sec. 170.30(b) further provides that a scientific procedures GRAS 
    determination requires the same quantity and quality of scientific 
    evidence as would be required to approve a food additive. Thus, such 
    information should be included in the notice summary. Several technical 
    documents that discuss the practical details of estimating consumer 
    exposure to a food substance are available from the agency.4
    ---------------------------------------------------------------------------
    
        \4\ For example, ``Recommendations for Submission of Chemical 
    and Technological Data for Direct Food Additive and GRAS Food 
    Ingredient Petitions'' (1993); ``Estimating Exposure to Direct Food 
    Additives and Chemical Contaminants in the Diet'' (1995); and 
    ``Recommendations for Chemistry Data for Indirect Food Additive 
    Petitions'' (1995).
    ---------------------------------------------------------------------------
    
        The notice summary may also include a comprehensive discussion of 
    scientific data, information, and methods that, in the notifier's view, 
    corroborate the GRAS determination. For example, for a substance whose 
    safety is established based on its identity, method of manufacture, and 
    characteristic properties, a notifier may describe a toxicological 
    study and rely on these data as corroborative. However, as with studies 
    that are relied on to support a GRAS determination, the comprehensive 
    discussion should fully describe such studies, identify the conclusions 
    drawn from such studies, and explain how these conclusions are relevant 
    to the GRAS determination.
        b. General availability of information supporting safety. The 
    inclusion of citations to published articles is customary scientific 
    practice and is the simplest way to demonstrate the general 
    availability of the information on which the notifier relies. Proposed 
    Sec. 170.36(c)(4)(i)(A) does not require that a notifier submit copies 
    of published information identified in the notice summary because, in 
    most cases, the agency does not intend to conduct its own detailed 
    evaluation of the data that the notifier relies on to support a 
    determination that a use of a substance is GRAS. Rather, the agency 
    intends to evaluate whether the notice summary establishes a basis to 
    conclude that there is expert consensus regarding the safety of use of 
    the substance.
        Under proposed Sec. 170.36(c)(4)(i)(A), notifiers should limit 
    published information citations to those that the notifier discusses 
    and relies on to support a GRAS determination or that are appropriately 
    discussed and explained because they may appear to be inconsistent with 
    a GRAS determination (see discussion of proposed 
    Sec. 170.36(c)(4)(i)(B)). Accordingly, the notifier should not cite 
    published information unless the cited information bears directly on 
    the GRAS determination. For example, a bibliography describing an 
    exhaustive literature search about a notified substance is of limited 
    or no value in supporting the common knowledge element of a GRAS 
    determination if the relevance of the cited literature is not readily 
    apparent or fully discussed. Moreover, such a bibliography would not, 
    absent a discussion of the relevance of the material cited to the GRAS 
    determination in question, fulfill the technical element of a GRAS 
    determination.
        c. Unfavorable information. Proposed Sec. 170.36(c)(4)(i)(B) 
    requires that the notice summary of a scientific procedures GRAS 
    determination include a comprehensive discussion of any reports of 
    investigations or other information (e.g., adverse event reports and 
    consumer complaints) that may appear to be inconsistent with the GRAS 
    determination. FDA is proposing this requirement as a prelude to 
    proposed Sec. 170.36(c)(4)(i)(C), which would require that the notice 
    summary include a basis to conclude that there is expert consensus 
    regarding the safety of use of the substance. In other words, in order 
    to meet the act's general recognition standard, all information, both 
    favorable and unfavorable, that bears on the safety of the substance 
    for its intended use must be considered.
        Proposed Sec. 170.36(c)(4)(i)(B) is consistent with the provision 
    in current Sec. 170.35(c)(1)(iv) and (c)(1)(v) (which are proposed for 
    deletion) that a GRAS affirmation petition include adverse information 
    or consumer complaints and be a representative and balanced submission 
    that includes known information, both favorable and unfavorable. 
    Proposed Sec. 170.36(c)(4)(i)(B) is also consistent with a similar 
    provision (Sec. 171.1(c) (21 CFR 171.1(c))) in the FAP regulations, 
    which requires that the petition must not omit without explanation any 
    reports of investigations that would bias an evaluation of the safety 
    of the food additive. Thus, the requirement in proposed 
    Sec. 170.36(c)(4)(i)(B) is appropriate because general recognition of 
    safety based upon scientific procedures requires the same quantity and 
    quality of scientific evidence required to obtain approval of the 
    substance as a food additive.
        d. Basis for concluding expert consensus. Proposed 
    Sec. 170.36(c)(4)(i)(C) requires that the notice summary of a 
    scientific procedures GRAS determination include the basis for 
    concluding, in light of the data and information described in the 
    notice, that there is a consensus among qualified experts that there is 
    reasonable certainty that the substance is not harmful under the 
    intended conditions of use. Thus, the notice summary must consider the 
    totality of the publicly available and corroborative evidence about the 
    safety of the substance for its intended use, including both favorable 
    and potentially unfavorable information.
        As discussed in section I.C of this document, the bases for 
    concluding that there is the requisite expert consensus may be quite 
    varied. For example, there could be a basis to conclude that the 
    necessary expert consensus exists if data published in the primary 
    scientific literature establish the safety of a substance for its 
    intended use and such data raise no safety questions that experts would 
    need to resolve. On the other hand, data published in the primary 
    scientific literature may not provide a basis for expert consensus if 
    those data raise unresolved safety questions. Alternatively, the 
    opinions of a specially convened expert panel or of an authoritative 
    body such as NAS may provide a basis for expert consensus. However, an 
    ongoing scientific discussion or controversy about safety concerns 
    raised by available data would make it difficult to provide a basis for 
    expert consensus about the safety of a substance for its intended use.
    5. Common Use GRAS Determination
        a. Technical evidence of safety. Proposed Sec. 170.36(c)(4)(ii)(A) 
    requires that the notice summary of a common use GRAS determination 
    include a comprehensive discussion of, and citations to, generally 
    available data and information that the notifier relies on to establish 
    safety, including evidence of a substantial history of consumption of 
    the substance by a significant number of consumers. Under current 
    Sec. 170.30(c)(1), in evaluating whether use of a substance is GRAS 
    through experience based on common use in food prior to January 1, 
    1958, FDA relies on information documenting that the ``common use in 
    food'' of a substance satisfies the definition in Sec. 170.3(f) such 
    that adverse health effects, if they occurred, could be noted. In other 
    words, a substance is not eligible for the
    
    [[Page 18950]]
    
    GRAS exemption merely because it was used in food before January 1, 
    1958, if such use were not sufficiently widespread.5
    ---------------------------------------------------------------------------
    
        \5\ For example, subsequent to the 1958 amendment, FDA required 
    that food additive petitions be submitted for several substances, 
    such as polysorbates (25 FR 1727, February 27, 1960), even though 
    those substances had been used in food prior to January 1, 1958, 
    because the pre-1958 consumption alone was not sufficient to 
    establish safety (24 FR 11079, December 31, 1959).
    ---------------------------------------------------------------------------
    
        The fact that GRAS status is determined through experience based on 
    common use in food does not preclude, in addition to information 
    documenting that a substance has a substantial history of consumption 
    for food use by a significant number of consumers, a discussion of 
    relevant data or information that bears on the safety of the substance 
    under its intended conditions of use. Thus, the notice summary may also 
    include a comprehensive discussion of scientific data or information 
    that, in the notifier's view, corroborates the common use GRAS 
    determination. With respect to toxicological studies that are viewed as 
    corroborative, the comprehensive discussion should fully describe the 
    studies, identify the conclusions drawn from such studies, and explain 
    how these conclusions are relevant to the GRAS determination.
        As discussed in section I.A of this document, it is the use of a 
    substance, rather than the substance itself, that is eligible for the 
    GRAS exemption. In addition, section 201(s) of the act makes a clear 
    distinction between qualifying for the GRAS exemption through 
    scientific procedures and qualifying for the GRAS exemption through 
    common use in food. Many substances that are GRAS for a specific use 
    through a common use GRAS determination could become the subject of 
    GRAS determinations for additional uses. It is important to note, 
    however, that an evaluation of whether an additional use of a substance 
    that is GRAS through experience based on common use in food is also 
    GRAS requires a scientific procedures GRAS determination when the use 
    in question was not common prior to January 1, 1958.
        b. General availability. As discussed for notifiers of a scientific 
    procedures GRAS determination, notifiers of a common use GRAS 
    determination should limit citations to published information to those 
    that the notifier discusses and relies on to support a GRAS 
    determination or that are appropriately discussed and explained because 
    they appear to be inconsistent with the GRAS determination.
        c. Unfavorable information. Proposed Sec. 170.36(c)(3)(ii)(B) 
    requires that the notice summary of a common use GRAS determination 
    include a comprehensive discussion of any reports of investigations or 
    other information that may appear to be inconsistent with the GRAS 
    determination. The legislative history of the 1958 amendment 
    demonstrates that Congress believed that there was no reason to conduct 
    specific tests to establish the safety of substances commonly used in 
    food because their history of common use established a presumption of 
    such safety (Ref. 1). However, nothing in the legislative history 
    suggests that Congress intended that subsequent reports of adverse 
    effects associated with the use of a substance in food be ignored in 
    the safety evaluation. A notice summary of a common use GRAS 
    determination should also address whether use was/is sufficiently 
    widespread that any substance-related adverse effects would be observed 
    and recorded. Where a substance has been used by a limited population, 
    6 for a limited period of time, or under circumstances that do not 
    lend themselves to the observation and recording of adverse effects, 
    the lack of reported adverse effects may not be meaningful.
    ---------------------------------------------------------------------------
    
         6 An exception is the use of a food substance in a limited 
    population such as infants, where such limited use may be part of a 
    demonstration of the safety of the substance for use by the limited 
    population (e.g., as an ingredient in an infant formula).
    ---------------------------------------------------------------------------
    
        d. Basis for concluding expert consensus. Proposed 
    Sec. 170.36(c)(4)(ii)(C) requires that the notice summary of a common 
    use GRAS determination include the basis for concluding, in light of 
    the data and information described in the notice, that there is a 
    consensus among qualified experts and that there is reasonable 
    certainty that the substance is not harmful under the intended 
    conditions of use. Thus, the notice summary must consider the totality 
    of the publicly available and corroborative evidence about the safety 
    of the substance for its intended use, including both favorable 
    information and potentially unfavorable information.
        FDA has previously discussed the common knowledge element as it 
    applies to a common use GRAS determination which reads as follows:
    
        For a substance to be GRAS on the basis of a history of common 
    use in food, there must be a consensus among the community of 
    qualified experts that the use of the substance is safe. For such a 
    consensus to be possible, information about the use of the substance 
    must be generally available. General availability is the result of 
    documentation of the information, usually by publication.
    
    (50 FR 27294 at 27295, July 2, 1985)
        In addition, under Sec. 170.30(c)(2), when the common use in food 
    occurred exclusively or primarily outside of the United States, a 
    common use GRAS determination requires that such use be documented by 
    published or other information and be corroborated by information from 
    a second, independent, source that confirms the history and 
    circumstances of use of the substance. Such information must be widely 
    available in the country in which the use occurred and readily 
    accessible to interested qualified experts in the United States.
    
    C. Agency Response
    
    1. Acknowledgment of Receipt
        Proposed Sec. 170.36(d) requires that, within 30 days of receipt of 
    a notice, FDA acknowledge receipt of the notice by informing the 
    notifier in writing of the date on which the notice was received. This 
    acknowledgment would serve as a means to establish the date of receipt, 
    which FDA is proposing to couple with certain aspects of the agency 
    response (see discussion of proposed Sec. 170.36 (d), (e), and (f) of 
    this document).
    2. 90-Day Response Letter
        Under the proposed notification procedure, FDA would not receive 
    the detailed data and information that support a GRAS determination. 
    Therefore, FDA would not be in a position to affirm a notifier's 
    conclusion that a use of a substance is GRAS, and the rulemaking part 
    of the GRAS affirmation process would not be necessary or appropriate. 
    Rather, FDA would evaluate whether the notice provides a sufficient 
    basis for the notifier's GRAS determination. For example, FDA may 
    question the GRAS status of use of a substance if the information 
    provided in a notice: (1) Does not adequately establish technical 
    evidence of safety; (2) is not generally available; (3) does not 
    convince the agency that there is the requisite expert consensus about 
    the safety of the substance for its intended use; or (4) is so poorly 
    presented that the basis for the GRAS determination is not clear. FDA 
    also may be aware of information that is not included in the notice but 
    raises important public health issues that lead the agency to question 
    GRAS status of use of the substance.
        FDA believes that this narrow agency evaluation would not have a 
    negative impact on public health because the agency is replacing a 
    voluntary
    
    [[Page 18951]]
    
    administrative process that was developed to provide official 
    recognition of a lawfully made GRAS determination with a different 
    voluntary administrative procedure. From a legal and regulatory 
    perspective, this substitution is neutral.
        This narrow evaluation would facilitate FDA's rapid response to the 
    notifier. Accordingly, under proposed Sec. 170.36(e), FDA would respond 
    to the notifier in writing within 90 days of receipt of the notice. In 
    some circumstances, the agency's response would not question the GRAS 
    determination. This response, however, would not be equivalent to an 
    agency affirmation of GRAS status because FDA would neither receive nor 
    review the detailed data and information that support the GRAS 
    determination. In addition, consistent with proposed Sec. 170.36(a)(2), 
    any response from FDA would not constitute compliance with 
    Sec. 101.14(b)(3)(ii) or with the requirements that the agency has 
    proposed (61 FR 36154) for new infant formula submissions.
        In other circumstances, the agency's response could include 
    identification of a problem with the notice. However, whether FDA 
    chooses to advise a notifier that the agency has identified a problem 
    with the notice, where the notice raises no important public health 
    issues, is a matter committed to the agency's discretion.
        FDA is proposing to respond in writing to a notifier in all 
    circumstances for the following reasons. First, a written response 
    would make clear that the agency's evaluation of a notice has come to 
    closure. Second, as discussed more fully in section X of this document, 
    FDA believes that a written response would facilitate international 
    trade. Third, as discussed more fully in section VI.F of this document, 
    FDA believes that a written response would be a useful element of any 
    file that the agency makes publicly accessible or any inventory that 
    the agency prepares of notices received under proposed Sec. 170.36.
        However, under a notification procedure, an agency response is not 
    imperative in those circumstances in which the agency chooses to raise 
    no question about the GRAS status of the intended use of the substance. 
    As discussed in sections I.A and II of this document, a manufacturer 
    may market a substance that the manufacturer determines is GRAS without 
    informing the agency or, if the agency were so informed, while the 
    agency is reviewing that information. Thus, FDA's proposal to respond 
    to a notifier in all circumstances does not alter a notifier's 
    prerogative under the statute to market a GRAS substance. Nonetheless, 
    as an alternative approach, the notification program could be 
    structured so that FDA responds to the notifier only when the agency 
    questions the GRAS status of the intended use of the substance. FDA 
    specifically requests comment on whether the agency should, in all 
    cases, provide a notifier with a letter at the conclusion of the 
    agency's evaluation of a notice. Such comments may result in a 
    modification to proposed Sec. 170.36(e).
        FDA has also considered whether the time for the agency's response 
    should be longer than 90 days, and specifically requests comment on 
    whether the proposed 90-day timeframe for an agency response should be 
    lengthened, e.g., to 120 days or 150 days. FDA's proposal to respond 
    within 90 days reflects both a commitment to operational efficiency and 
    a belief that the agency's evaluation of whether a notice provides a 
    sufficient basis for a GRAS determination could likely be accomplished 
    in such a period. However, FDA's expectation that it could respond 
    within 90 days is in part predicated on its estimate, which is 
    discussed more fully in the agency's analysis of the information 
    collection requirements of this document, that the agency would receive 
    approximately 50 notices per year. Accordingly, although comments on 
    the information collection requirements of this document are submitted 
    directly to the Office of Information and Regulatory Affairs, OMB, the 
    agency also requests comment directly to FDA on the number of notices 
    that manufacturers anticipate submitting on an annual basis. Such 
    information may result in a modified timeframe for the agency's 
    response.
    3. Subsequent Agency Action
        FDA is continuously evaluating the safety of substances in the food 
    supply. In some cases, FDA may consider whether an emerging body of 
    scientific knowledge raises questions about the continued safe use of a 
    food additive or of a substance whose use was listed as GRAS, affirmed 
    as GRAS, or commonly considered to be GRAS by the food industry. 
    Likewise, FDA may consider whether specific information brought to the 
    agency's attention (e.g., through routine correspondence from 
    interested parties or through a citizen petition) raises such safety 
    questions. In most cases, the information that comes to FDA's attention 
    does not demonstrate a health hazard, and the scientific issues are 
    resolved upon consideration by the agency. Thus, the agency does not 
    routinely publicize safety issues that it is considering, or 
    reconsidering, concerning the safety of a substance or class of 
    substances that is used in food unless action by the agency is 
    necessary for public health protection.
        Similarly, FDA may direct resources to exploring issues raised by a 
    GRAS notice even though such issues do not, on their face, appear to be 
    significant public health issues. Alternatively, FDA may, at some point 
    after its 90-day response to the notifier, receive additional 
    information about a notified substance that raises questions about the 
    safety of that substance. If, after issuing a 90-day response letter, 
    questions develop for the agency regarding the GRAS status of a use of 
    a substance, FDA may subsequently advise the notifier and other 
    interested parties of those questions.
        In such circumstances, FDA ordinarily expects to advise a notifier 
    by letter that the agency has subsequently identified a problem with 
    the notice. As discussed more fully in section VI.F of this document, 
    such a letter would be placed in a publicly accessible file so that 
    other interested parties would become aware of the agency's position. 
    Alternatively, FDA may, in accordance with Secs. 170.35(b)(4) and 
    170.38, publish a notice in the Federal Register determining that use 
    of a substance is not GRAS and is a food additive subject to section 
    409 of the act. Importantly, however, when faced with a public health 
    hazard, the existence of such rulemaking authority would not preclude 
    other agency action, including seizure and injunction, to remove from 
    the market a product that is an unapproved food additive.
        As discussed in section VI.A of this document, FDA has recently 
    proposed that a ``new infant formula'' submission required under 
    section 412 (c) and (d) of the act include the basis on which each 
    ingredient is determined to be safe and suitable under the food safety 
    provisions of the act (proposed Sec. 106.120(b)(6)(ii); 61 FR 36154 at 
    36217). The agency could receive a notice under proposed Sec. 170.36 
    concerning a GRAS determination for a broad use of a substance in foods 
    and subsequently receive a new infant formula submission that lists the 
    substance as an ingredient in a new infant formula and asserts that the 
    use of the substance in infant formula is GRAS. In such circumstances, 
    FDA could choose to reexamine the notice previously received under 
    proposed Sec. 170.36. If, following such reexamination, the agency 
    questions whether use of the substance in infant formula is GRAS, the 
    agency could so inform the person who submitted the GRAS notice under 
    proposed Sec. 170.36.
    
    [[Page 18952]]
    
    D. Appeals
    
        FDA recognizes that in some cases a notifier may disagree with the 
    agency if the notifier receives a response advising that FDA has 
    identified a problem with the notice. FDA has recently reviewed the 
    vehicles, provided in part 10 (21 CFR part 10) of its regulations, that 
    any person or firm may use to appeal an agency employee's decision (61 
    FR 9181 at 9184, March 7, 1996). Although an agency response to a 
    notice under proposed Sec. 170.36 does not constitute an agency 
    decision on the GRAS status of a substance, FDA is advising that it 
    will consider any of the existing appeals processes that are described 
    below as an appropriate vehicle to engage the agency in cases where a 
    notifier disagrees with a response received under proposed Sec. 170.36.
        Under Sec. 10.75, an interested person may request internal agency 
    review of an agency decision made by anyone other than the 
    Commissioner. Such review ordinarily would be by the employee's 
    supervisor, but may move up the management ranks to the Center Director 
    or to the Office of the Commissioner if the issue cannot be resolved, 
    important policy matters are present, or it would be in the public 
    interest. Sections 10.25 and 10.33 permit an interested person to 
    petition the Commissioner to review any administrative action. The 
    regulations also include less formal methods of appeal. For example, 
    under Sec. 10.65, an interested person may correspond or meet with FDA 
    about any matter under FDA's jurisdiction. Finally, any person with 
    concerns about an agency response to a notice received under proposed 
    Sec. 170.36 may contact FDA's Office of the Chief Mediator and 
    Ombudsman (the Ombudsman's Office). The Ombudsman's Office, which 
    reports directly to the Commissioner, works on resolving issues and 
    conflicts that arise in any FDA component. The Ombudsman's staff is 
    available to discuss options, explain FDA's practices and procedures, 
    and suggest approaches for resolution. When appropriate, the staff of 
    the Ombudsman's Office may contact FDA's staff involved in the issue 
    and mediate a dispute.
    
    E. Public Disclosure and Accessibility
    
    1. Public Disclosure
        Proposed Sec. 170.36(f)(1) provides that any GRAS exemption claim 
    submitted under proposed Sec. 170.36(c)(1) of this section be 
    immediately available for public disclosure on the date the notice is 
    received. As discussed in section VI.B.1 of this document, any person 
    who makes a GRAS determination is responsible for ensuring that the 
    determination complies with the provisions of Sec. 170.30, regardless 
    of whether that person notifies the agency about the determination. 
    Further, the common knowledge element of a GRAS determination signifies 
    that neither the common or usual name of the substance, the intended 
    use of the substance, nor the basis for the GRAS determination can be 
    confidential.
        Proposed Sec. 170.36(f)(1) further provides that all remaining data 
    and information in a notice be available for public disclosure, in 
    accordance with part 20 (21 CFR part 20), on the date the notice is 
    received. The common knowledge element of a GRAS determination 
    signifies that neither the detailed information about the identity of 
    the substance nor the information needed to establish technical 
    evidence of safety can be confidential. Therefore, FDA assumes that a 
    notice will not contain any information that is protected from public 
    disclosure. Moreover, because a GRAS substance may be marketed without 
    prior approval, FDA assumes that, in most cases, submission of a notice 
    will not reflect the notifier's plans about the timing of 
    commercialization, which is arguably confidential commercial 
    information (Sec. 20.61(b)).
        A notifier who considers that certain information in a submission 
    should not be available for public disclosure should identify as 
    confidential the relevant portions of the submission for FDA 
    consideration. FDA will review the identified information, determine 
    whether that information is exempt from public disclosure under part 
    20, and release or protect the information in accordance with that 
    determination. FDA advises that, in most cases, the agency is likely to 
    determine that all information submitted to support a GRAS 
    determination is available for public disclosure.
    2. Public Accessibility
        The food industry's basic need to know whether a food substance is 
    in compliance with applicable provisions of the act originally 
    persuaded the agency to clarify the regulatory status of a multitude of 
    food substances by publishing the GRAS list. Under this proposal, the 
    current GRAS list (i.e., current part 182) and the regulations listing 
    uses of a substance that FDA has affirmed as GRAS (i.e., current parts 
    184 and 186 (21 CFR parts 184 and 186)) would remain in the agency's 
    codified regulations. In addition, FDA is retaining the process whereby 
    the agency may, on its initiative, review the GRAS status of a 
    substance and, if appropriate, establish a regulation in part 184 or 
    part 186 affirming such use as GRAS. However, if this proposal becomes 
    final, the existing process whereby an interested person may petition 
    FDA to affirm the GRAS status of use of a substance and list such 
    affirmed uses in part 184 or part 186 would be eliminated.
        FDA believes that there would be considerable interest, from a 
    broad segment of the public, including members of the regulated 
    industry, other Federal, State, and local government agencies, 
    international government agencies, and public interest groups, in 
    notices received under proposed Sec. 170.36. Such groups likely would 
    want to know whether FDA is aware that a substance is being used in 
    food on the basis of the GRAS exemption and whether FDA has advised the 
    notifier that it has identified a problem with the notice. Therefore, 
    FDA is proposing to establish a procedure whereby all members of the 
    public could readily access such information. Moreover, such a 
    procedure would be in keeping with the agency's goals in meeting the 
    Reinventing Food Regulations.
        All GRAS petitions are currently on public display at the Dockets 
    Management Branch (DMB) because the petition process includes informal 
    rulemaking and DMB is the usual repository for information that is 
    publicly available during informal rulemaking. However, FDA sees no 
    need to place the entire GRAS notice on public display at DMB because, 
    under the proposed notification procedure, the agency will no longer be 
    engaged in rulemaking. Moreover, a process of maintaining a copy of all 
    notices at DMB would require that an additional copy be submitted and 
    that an administrative copy be maintained at two locations (i.e., CFSAN 
    as well as DMB). Such a process would be administratively inefficient.
        Nonetheless, FDA has considered the best way to make the 
    information from the proposed notification procedure readily accessible 
    to the public. FDA has tentatively concluded that making both the GRAS 
    exemption claim provided under proposed Sec. 170.36(c)(1) and all 
    letters issued by the agency relevant to each claim easily accessible 
    to the public is the most direct and administratively efficient way of 
    meeting the needs of the public. Accordingly, under proposed 
    Sec. 170.36(f)(2), the following information would be readily 
    accessible for public review and copying: (1) A copy of all GRAS 
    exemption claims received under proposed Sec. 170.36(c)(1); (2) a copy 
    of all
    
    [[Page 18953]]
    
    letters issued by the agency under proposed Sec. 170.36(e); and (3) a 
    copy of any subsequent letter issued by the agency.
        FDA considered whether the agency should only make a GRAS exemption 
    claim readily accessible if the agency has not advised a notifier that 
    it has identified a problem with the notice. The agency decided to make 
    all claims and responses readily accessible because such a system will 
    properly underscore the notifier's acceptance of responsibility for the 
    determination. Proposed Sec. 170.36(f)(2) makes explicit to notifiers 
    that their notice to the agency about a GRAS determination is a public 
    claim.
        Initially, FDA intends to prepare a file containing the information 
    specified by proposed Sec. 170.36(f)(2) and to place that file on 
    public display at DMB. FDA is planning this approach because DMB is a 
    common repository for publicly available files. Alternatively, FDA 
    could make the file accessible for inspection at the agency's Freedom 
    of Information Office or, in keeping with the current procedures for 
    public inspection of the information FDA considered and relied on to 
    reach a decision on an FAP, at CFSAN. Although FDA has tentatively 
    concluded that it would be best to provide for public accessibility at 
    DMB because the public is already accustomed to obtaining information 
    relating to GRAS substances at that location, the agency requests 
    comment on this matter.
        FDA is not proposing to codify how or where the information 
    prescribed by proposed Sec. 170.36(f)(2) would be made accessible 
    because any mechanism that appears in the agency's regulations will 
    bind the agency to its provisions. In keeping with the agency's goals 
    in meeting the Reinventing Food Regulations, FDA wishes to maintain 
    flexibility to improve the process for public accessibility, 
    particularly as the agency gains experience with electronic modes of 
    information dissemination. FDA is aware that the public review of hard 
    copy (i.e., paper) files in a public reading room may become obsolete 
    as electronic technology for public dissemination of information 
    advances.
        FDA requests comment on whether proposed Sec. 170.36(f)(2) is an 
    effective and efficient means to provide the public with ready access 
    to information from the proposed notification procedure.
    
    F. Inventory
    
        Proposed Sec. 170.36(f)(2) would not require that FDA maintain an 
    inventory of the information retained in the publicly accessible file. 
    Consequently, such an inventory would be a new record within the 
    meaning of Sec. 20.24 and FDA would not be required to prepare such an 
    inventory in response to a FOIA request. However, FDA recognizes the 
    utility and importance of an inventory of notices received under 
    proposed Sec. 170.36 and of the agency's response to those notices, 
    particularly for persons without ready access to the agency's DMB. FDA 
    also recognizes that many members of the public would prefer to access 
    basic information relevant to GRAS notices in a streamlined format. FDA 
    further recognizes that the agency itself can most efficiently carry 
    out its own responsibilities (e.g., with respect to monitoring imports 
    of food products) by having basic information relevant to GRAS notices 
    available in such a format.
        Therefore, FDA intends to maintain an inventory of notices 
    received, the agency's response, and any subsequent relevant agency 
    correspondence. Such an inventory would be an administratively 
    efficient mechanism of accounting for the information residing in the 
    publicly accessible file. Such an inventory also would complement the 
    current agency regulations tabulating substances that are listed (part 
    182) or affirmed (parts 184 and 186) as GRAS.
        FDA has tentatively concluded that any inventory of notices 
    received should be an adjunct to proposed Sec. 170.36(f)(2), rather 
    than the sole means of distributing the information available from the 
    notification procedure, because the agency could place the GRAS 
    exemption claims and the letters issued by the agency in the publicly 
    accessible file faster than it could amend an inventory. However, FDA 
    is not proposing to codify the inventory as an adjunct to proposed 
    Sec. 170.36(f)(2) because such an inventory would require continuous 
    amendment and the administrative procedures required to amend a 
    codified inventory would be too cumbersome to meet the needs of the 
    public and the agency efficiently.
        FDA is also not proposing to mention the availability of the 
    inventory in its codified regulations. In keeping with the agency's 
    goals in meeting Reinventing Food Regulations, FDA believes that 
    refraining from codifying any aspect of the inventory will provide the 
    agency with maximum flexibility to improve the process by which the 
    inventory is updated and maintained.
        Initially, FDA intends that such an inventory would be publicly 
    accessible in any file maintained in accordance with proposed 
    Sec. 170.36(f)(2), e.g., at DMB. FDA could also make such an inventory 
    available through prevailing publicly accessible electronic modes, such 
    as the agency's home page on the contemporary World Wide Web. FDA 
    requests comment on making any inventory prepared by the agency 
    available through such electronic modes.
    
    VII. Effect of the Proposed Notification Procedure on Existing GRAS 
    Petitions
    
        Under the current GRAS affirmation process, the agency conducts a 
    preliminary examination of the data and information submitted in the 
    petition. If FDA finds that the submitted information conforms to the 
    requirements established under Secs. 170.30 and 170.35, FDA makes an 
    administrative decision to file the petition and publishes a notice in 
    the Federal Register to that effect.
        At this time, approximately 60 filed GRAS affirmation petitions are 
    pending at FDA. These petitions were filed with the agency under an 
    administrative process that the agency is proposing to remove. 
    Therefore, if this proposal becomes final, the administrative process 
    that FDA would use to bring these petitions to closure will no longer 
    be operative. Moreover, FDA is proposing to eliminate the GRAS 
    affirmation process in order to increase effectiveness and efficiency. 
    The continued commitment of agency resources to complete the GRAS 
    petition process for pending petitions would be contrary to one of the 
    agency's goals in this rulemaking.
        FDA recognizes that persons who have a pending GRAS affirmation 
    petition have invested time and resources in those petitions. 
    Therefore, proposed Sec. 170.36(g)(1) stipulates that any GRAS 
    affirmation petition filed under Sec. 170.35 prior to the date that a 
    final rule based on this proposal becomes effective, and still pending 
    as of such effective date, will be presumptively converted to a GRAS 
    notice under proposed Sec. 170.36. This conversion will allow the 
    agency to bring filed GRAS affirmation petitions to closure, albeit 
    under a different process than the one to which they were submitted.
        However, the proposed notification procedure has certain 
    requirements that have no specific counterpart in the petition process. 
    In particular, under the notification procedure a notifier explicitly 
    accepts full responsibility for the GRAS determination by signing a 
    GRAS exemption claim (under proposed Sec. 170.36(c)(1)). In contrast, 
    under the petition process a petitioner requests that FDA attest to a 
    GRAS determination. Thus, FDA cannot assume that all persons who 
    submitted
    
    [[Page 18954]]
    
    a GRAS petition would in fact be willing to accept full responsibility 
    for the determination.
        Moreover, the GRAS exemption claim in proposed Sec. 170.36(c)(1) 
    would be a complete and separate section of a GRAS notice that could 
    stand alone and would contain basic information in a consistent format. 
    As discussed, under proposed Sec. 170.36(f)(2) the agency would use the 
    GRAS exemption claim to effectively and efficiently inform the public 
    about received notices. Thus, logic compels that a GRAS exemption claim 
    filed under proposed Sec. 170.36(g) include all elements of the claim 
    required under proposed Sec. 170.36(c)(1), rather than only those 
    elements that have no counterpart in the GRAS affirmation petition 
    process.
        Accordingly, proposed Sec. 170.36(g)(2) provides that any person 
    who submitted a GRAS affirmation petition that is converted to a notice 
    under the provisions of proposed Sec. 170.36(g)(1) may amend such 
    converted petition to satisfy the requirements of proposed Sec. 170.36 
    by submitting to the agency a claim, dated and signed by the notifier 
    (i.e., the former petitioner), that a particular use of a substance is 
    exempt from the premarket approval requirements of the act because the 
    notifier has determined that such use is GRAS. Proposed Sec. 170.36 
    (g)(2)(i) through (g)(2)(vi) describe the format of the GRAS exemption 
    claim that would amend a converted GRAS affirmation petition to satisfy 
    the requirements of a notice under proposed Sec. 170.36. This claim 
    format is similar to that required under proposed Sec. 170.36(c)(1) but 
    has been modified in two particulars (i.e., proposed Sec. 170.36 
    (g)(2)(ii) and (g)(2)(vi)) to take into account the fact that the data 
    and information to support the GRAS determination have already been 
    submitted to the agency in the applicable GRAS petition.
        Proposed Sec. 170.36(g)(2)(i) requires that the GRAS exemption 
    claim include the name and address of the notifier. As with proposed 
    Sec. 170.36(c)(1)(i), this is necessary for full identification of the 
    person who accepts responsibility for the claim. This also is necessary 
    so that the agency can administer the amendment to the converted 
    petition according to the provisions of proposed Sec. 170.36 (d) and 
    (e) (see proposed Sec. 170.36(g)(3)(i)).
        Proposed Sec. 170.36(g)(2)(ii) requires that the GRAS exemption 
    claim include the applicable GRAS affirmation petition number. The 
    petition number is the simplest way to identify the converted petition 
    that is being amended.
        Proposed Sec. 170.36(g)(2)(iii) requires that the GRAS exemption 
    claim include the common or usual name of the substance that was the 
    subject of the converted GRAS affirmation petition (i.e., the notified 
    substance). As with proposed Sec. 170.36(c)(1)(ii), this is necessary 
    to identify the notified substance as well as to identify whether there 
    are any labeling issues that need to be addressed. FDA is satisfied 
    that detailed identity information, such as that described in proposed 
    Sec. 170.36(c)(2), will be present in the referenced petition because, 
    under current Sec. 170.35(c)(1)(i), FDA requires that a GRAS petition 
    contain such information as a prerequisite to filing the petition.
        Proposed Sec. 170.36(g)(2)(iv) requires that the GRAS exemption 
    claim include the applicable conditions of use that are supported by 
    data and information in the referenced GRAS petition, including the 
    foods in which the notified substance is to be used, levels of use in 
    such foods, and the purposes for which the notified substance is used, 
    including, when appropriate, a description of the population expected 
    to consume the substance. As with proposed Sec. 170.36(c)(1)(iii), this 
    information describing the conditions of use is necessary to delineate 
    the boundaries of the GRAS exemption claim consistent with section 
    201(s) of the act, which states that a GRAS substance must be generally 
    recognized as safe ``under the conditions of its intended use.'' 
    Importantly, a petitioner who amends a converted GRAS affirmation 
    petition to satisfy the requirements of a notice may do so only for the 
    intended use that was the subject of the GRAS affirmation petition. Any 
    additional use(s) would be the subject of a separate notice under 
    proposed Sec. 170.36(c).
        Proposed Sec. 170.36(g)(2)(v) requires that the GRAS exemption 
    claim identify the basis for the GRAS determination as scientific 
    procedures or experience based on common use in food. As discussed in 
    section I.B.4 of this document, under Sec. 170.30, the requirements for 
    a scientific procedures GRAS determination are different from those for 
    a common use GRAS determination. The basis for a GRAS determination is 
    thus fundamental to the GRAS exemption claim.
        Proposed Sec. 170.36(g)(2)(vi) requires that the GRAS exemption 
    claim include either a statement that the complete record that supports 
    the GRAS determination has already been submitted to the agency in the 
    relevant GRAS petition (proposed Sec. 170.36(g)(2)(vi)(A)) or a 
    statement that all data and information that are the basis for the GRAS 
    determination are available for FDA review and copying or will be sent 
    to FDA upon request (proposed Sec. 170.36(g)(2)(vi)(B)). Proposed 
    Sec. 170.36(g)(2)(vi) takes into account the fact that, in many cases, 
    a petitioner has already submitted the complete record that supports 
    the GRAS determination. Alternatively, proposed Sec. 170.36(g)(2)(vi) 
    provides to the person who submitted a GRAS petition the option of 
    agreeing to provide upon request any additional information that 
    supports the GRAS determination but was not included in the GRAS 
    petition. As discussed with respect to proposed Sec. 170.36(c)(1)(v), 
    FDA might conduct random audits of such data and information or conduct 
    an audit on a broad issue or class of products if the issue or use of a 
    class of products raises important public health issues.
        FDA requests comment on proposed Sec. 170.36(g) as a mechanism for 
    administering pending GRAS affirmation petitions if the proposed 
    notification procedure becomes final. Proposed Sec. 170.36(g) would not 
    preclude any person who had a filed GRAS petition prior to the 
    effective date of a final GRAS notification rule from submitting a 
    notice of a claim for exemption according to the provisions of proposed 
    Sec. 170.36(c) or from submitting an FAP under Sec. 171.1 and 
    requesting that FDA cross reference the information contained in the 
    filed GRAS petition in accordance with Sec. 171.1(b).
    
    VIII. Interim Policy
    
        Between the time of publication of this proposal and any final rule 
    based on this proposal, FDA invites interested persons who determine 
    that a use of a substance is GRAS to notify FDA of such GRAS 
    determinations as described in proposed Sec. 170.36 (b) and (c). In 
    general, the agency would administer the notices as described in 
    proposed Sec. 170.36 (d) through (f) (i.e., FDA would acknowledge 
    receipt of the notice, respond in writing to the notifier, and make 
    publicly accessible a copy of all GRAS exemption claims and the 
    agency's response). However, although FDA would make a good faith 
    effort to respond within the proposed 90-day timeframe, the agency 
    would not be bound by such a timeframe. FDA will determine whether its 
    experience in administering such notices suggests modifications to the 
    proposed procedure.
        FDA realizes that some individuals who have a filed GRAS 
    affirmation petition pending at the agency may be interested in 
    converting such petition to a notice under proposed Sec. 170.36(g) or
    
    [[Page 18955]]
    
    in submitting a complete notice for the petitioned use under proposed 
    Sec. 170.36 (b) and (c). FDA invites such petitioners to submit an 
    amendment in accordance with proposed Sec. 170.36(g)(2) or to submit a 
    complete notice for the petitioned use in accordance with proposed 
    Sec. 170.36 (b) and (c). FDA would administer such notice or amendment 
    as described in proposed Sec. 170.36 (d) through (f). However, during 
    the interim period FDA would not continue to commit resources to review 
    of a GRAS affirmation petition if the agency receives an amendment in 
    accordance with proposed Sec. 170.36(g)(2) or receives a complete 
    notice concerning the petitioned use.
        FDA will consult upon request with interested persons who seek 
    additional guidance in preparing a notice because such consultation may 
    identify sections of the proposed procedure that may require 
    clarification in any final rule based on the proposal.
    
    IX. Conforming Amendments
    
        This proposal would eliminate the GRAS petition process set out in 
    Sec. 170.35(c). Therefore, FDA is proposing conforming amendments to 
    revise current Secs. 184.1(b)(1) and 186.1(b)(1) by removing the last 
    sentence of each paragraph. These sentences provide that persons 
    seeking FDA approval of an independent determination that a use of a 
    food substance is GRAS may submit a petition in accordance with 
    Sec. 170.35.
        Consistent with the proposed elimination of the GRAS petition 
    process set out in Sec. 170.35(c), FDA is also proposing a conforming 
    amendment to revise current Sec. 170.38(a) to: (1) Remove the provision 
    that the Commissioner may, in accordance with Sec. 170.35(c)(5), 
    publish a notice in the Federal Register determining that a substance 
    is not GRAS and is a food additive subject to section 409 of the act 
    and (2) retain the provision in Sec. 170.38(a) that the Commissioner 
    may, in accordance with Sec. 170.35(b)(4) (i.e., on his/her own 
    initiative), publish such a notice in the Federal Register. 
    Importantly, however, when faced with a public health hazard, the 
    existence of such rulemaking authority would not preclude other agency 
    action, including seizure and injunction, to remove from the market a 
    product that is an unapproved food additive.
    
    X. International Harmonization
    
        FDA is committed to international harmonization of regulatory 
    requirements and guidelines that preserve and enhance the agency's 
    ability to accomplish its public health mission, enhance regulatory 
    effectiveness by providing more consumer protection with scarce 
    government resources, and increase worldwide access to safe and high 
    quality food products (60 FR 53078, October 11, 1995). FDA is not aware 
    of a provision in the laws of any other country that is equivalent to 
    the GRAS exemption. On the other hand, the laws of other countries 
    provide exemptions (e.g., for ``natural'' products) that have no 
    equivalent under the act. Thus, the international community is already 
    accustomed to operating in accordance with a variety of regulatory 
    approaches for substances added to food. FDA's proposed substitution of 
    a GRAS notification procedure for the current GRAS petition process 
    would not impose any new requirements that would affect imported food 
    products.
        Under the current petition process, FDA makes a public announcement 
    that a petition has been filed and incorporates an affirmed use of a 
    substance into a codified list. Under the proposed notification 
    procedure, FDA would make readily accessible to the public, including 
    international agencies and firms, the notice's ``GRAS exemption 
    claim,'' which would include a succinct description of the notified 
    substance, the applicable conditions of use, and the basis for the GRAS 
    determination (i.e., through scientific procedures or through 
    experience based on common use in food). FDA would also make readily 
    accessible to the public the agency's response to the notice. Further, 
    under the act, a variety of substances that must be declared on the 
    food label are exempt from premarket approval on the basis of the GRAS 
    exemption and are not included on any government list or inventory of 
    substances that are used lawfully in the U.S. food supply. Operation of 
    either the petition process or the proposed notification procedure does 
    not change that fact.
        FDA recognizes that interested persons may want to know the 
    official regulatory status of a food substance in the United States 
    prior to using that substance in foods that will enter international 
    commerce. FDA also recognizes that the proposed agency response to a 
    GRAS notice may have less weight in the international community than 
    the agency's affirmation of GRAS status. However, as a practical 
    matter, FDA has announced only approximately 30 GRAS affirmations in 
    the 10 years preceding this proposed rule. This small number of GRAS 
    affirmations has a minimal impact on considerations of international 
    trade.
        For these reasons, FDA does not anticipate that the proposed 
    substitution of a GRAS notification procedure for the GRAS petition 
    process will have any impact on international trade. Nevertheless, the 
    agency invites comment on this matter from the international community 
    and from firms who import food products into the United States or who 
    export U.S. made food products.
    
    XI. Food Substances Used in Animal Feed
    
        FDA's regulations regarding the eligibility of substances used in 
    animal food or feeds for classification as GRAS, and the procedures for 
    affirmation of GRAS status for such substances, are codified at 
    Secs. 570.30 and 570.35, respectively. The requirements described in 
    these regulations are parallel to the requirements for GRAS substances 
    that are used in human food, although some requirements of Sec. 170.30 
    have no corresponding requirement in Sec. 570.30. As an example 
    relevant to this rulemaking, the requirements of Sec. 570.30(c) are 
    identical to the requirements of Sec. 170.30(c)(1), but Sec. 570.30(c) 
    has not been amended to describe the requirements for a common use GRAS 
    determination based on history of use when that history of use occurred 
    primarily or exclusively outside the United States. In addition, the 
    agency's GRAS review did not extend to the use of food substances in 
    animal food or feeds. Thus, Sec. 570.30 does not contain provisions 
    analogous to Sec. 170.30 (e) and (f).
        The general provisions in subpart A of part 184 were issued under 
    the auspices of the agency's comprehensive review of GRAS substances. 
    Because this agency review did not extend to the use of food substances 
    in animal food or feeds, the agency did not issue a corresponding 
    subpart A in part 584 (21 CFR part 584). Therefore, any proposed rule 
    to modify Secs. 570.30 and 570.35 would require no conforming 
    amendments in part 584.
        FDA is also proposing to amend the provisions of Sec. 570.30 that 
    are parallel to the provisions of current Sec. 170.30 (i.e., 
    Sec. 570.30 (a) and (b)) because Secs. 170.30 and 570.30 implement the 
    same statutory provisions. Therefore, it is important for the agency's 
    standards concerning GRAS substances to be consistent with respect to 
    substances used in human food and substances used in animal food or 
    feeds.
        FDA is also proposing to eliminate the GRAS affirmation petition 
    process provided for in Sec. 570.35 (a) and (c) because the 
    corresponding process for substances used in human food is being 
    eliminated. Although the GRAS
    
    [[Page 18956]]
    
    affirmation process has rarely been employed for substances used in 
    animal food or feeds, FDA believes that it is appropriate to provide 
    the option of a GRAS notification procedure for animal food or feeds 
    that would be parallel to proposed Sec. 170.36. Therefore, in proposed 
    Sec. 570.36 the agency is proposing a GRAS notification procedure for 
    substances used in animal food or feeds. Finally, FDA is proposing to 
    revise current Sec. 570.38(a) as a conforming amendment required by 
    removing the current GRAS affirmation petition process for substances 
    used in animal food or feeds.
        With regard to the notification procedure, FDA's proposal for 
    substances that would be used in animal food or feeds is for practical 
    purposes identical to FDA's proposal for substances that would be used 
    in human food. As discussed in more detail throughout this document, 
    FDA is specifically requesting comment on the following issues 
    concerning the proposed regulations for substances that would be used 
    in human food: (1) Whether it would be appropriate to require or 
    recommend that the submission include an electronic copy, in addition 
    to three paper copies, of some or all of the notice; (2) the proposed 
    requirement that, in all cases, FDA respond to the notifier; (3) 
    whether the agency should be permitted more than 90 days to respond to 
    a GRAS notice; (4) the number of notices that notifiers anticipate 
    submitting on an annual basis; (5) the agency's proposal to provide the 
    public with ready access to information from the proposed notification 
    procedure and the location for such information; (6) whether any 
    inventory prepared by the agency should be available through electronic 
    modes; (7) its proposal for administering pending GRAS affirmation 
    petitions if the proposed notification procedure becomes final; and (8) 
    whether the proposed substitution of a GRAS notification procedure for 
    the GRAS petition process would have any impact on international trade. 
    FDA specifically requests comments on these same issues for the 
    proposed regulations concerning substances that would be used in animal 
    foods or feed.
        In the case of substances that would be used in animal feed, FDA is 
    particularly concerned about the practical implications of a 90-day 
    response period, because, to date, the agency has received fewer than 
    10 GRAS affirmation petitions for substances that would be used solely 
    in animal food or feed. Should the number of notices received under a 
    GRAS notification program exceed more than a few notices per year, 
    agency resources devoted to the animal feed program likely would be 
    insufficient to evaluate, within the proposed 90-day timeframe, whether 
    the notice provides a sufficient basis for a GRAS determination. Thus, 
    comments to the proposal may justify that the agency adopt, in a final 
    rule, a longer timeframe for notifications concerning substances used 
    in animal feed.
        The agency recognizes that notifiers may have questions concerning 
    the common or usual name for a substance that would be used in animal 
    feeds. FDA advises that, in such circumstances, a notifier should 
    consult with the Division of Animal Feeds in FDA's Center for 
    Veterinary Medicine.
    
    XII. Summary of the Proposal
    
        FDA is proposing to clarify current Sec. 170.30 regarding the 
    eligibility of the use of a substance for exemption from the act's 
    premarket approval requirements based on a GRAS determination. 
    Specifically, FDA is proposing to amend current Sec. 170.30(a) to 
    clarify that general recognition of safety requires that there be 
    common knowledge among the qualified expert community that there is 
    reasonable certainty that the substance is not harmful under the 
    intended conditions of use. This amendment would also clarify that a 
    GRAS substance is neither more safe nor less safe than an approved food 
    additive, and that the distinction between a GRAS substance and an 
    approved food additive is in the common knowledge of, and expert 
    consensus about, that safety.
        In addition, FDA is proposing two changes to current 
    Sec. 170.30(b). First, FDA is proposing to clarify the types of 
    technical evidence of safety that ordinarily would constitute common 
    knowledge about a substance that is GRAS through scientific procedures. 
    FDA is proposing this change because the quantity and quality of 
    scientific evidence required to obtain approval of a substance as a 
    food additive vary considerably depending upon the estimated dietary 
    exposure to the substance and the chemical, physical, and physiological 
    properties of the substance. Second, FDA is proposing to clarify the 
    role of publication in satisfying the common knowledge element of the 
    GRAS standard because publication is ordinarily required, but may not 
    always be sufficient, to satisfy this element. For consistency with 
    these proposed amendments, FDA is also proposing to amend the 
    definition of ``scientific procedures'' in Sec. 170.3(h).
        In keeping with the Reinventing Food Regulations, FDA is proposing 
    to replace the current voluntary GRAS affirmation process with a 
    voluntary procedure whereby any person may notify FDA of a GRAS 
    determination. The notice would include a ``GRAS exemption claim,'' 
    dated and signed by the notifier, that would provide, in a consistent 
    format, specific information about a GRAS determination. This claim 
    would include a succinct description of the notified substance, the 
    applicable conditions of use, and the basis for the GRAS determination. 
    The GRAS exemption claim would also include a statement that the 
    information supporting the GRAS determination was available for FDA 
    review and copying or would be sent to FDA upon request. In addition to 
    the GRAS exemption claim, the notice would include detailed information 
    about the identity of the notified substance and a detailed discussion 
    of the basis for the notifier's GRAS determination.
        FDA would evaluate whether the notice provides a sufficient basis 
    for a GRAS determination and whether information in the notice or 
    otherwise available to FDA raises issues that lead the agency to 
    question whether use of the substance is GRAS. Within 90 days from the 
    date of receipt of the notice, FDA would respond to the notifier in 
    writing and could advise the notifier that the agency has identified a 
    problem with the notice. A response that does not advise that the 
    agency has identified a problem with the notice would not be equivalent 
    to an affirmation of GRAS status by the agency.
        For each notice received, FDA would make readily accessible to the 
    public the GRAS exemption claim and the agency's response. Although FDA 
    would maintain a readily accessible inventory of notices received and 
    the agency's response to them, this inventory would be neither codified 
    nor referenced in the agency's regulations.
        Under the proposal, all GRAS affirmation petitions that were filed 
    by FDA under Sec. 170.35 prior to the effective date of a GRAS 
    notification final rule and still pending as of that date would be 
    presumptively converted to a notice on that date. Any person who had 
    submitted a GRAS affirmation petition that is converted to a notice 
    could: (1) Amend such converted petition to satisfy the requirements of 
    the notification procedure by submitting to the agency a modified GRAS 
    exemption claim; (2) submit an FAP for the substance and request that 
    FDA cross reference the information in the GRAS affirmation petition; 
    or (3) submit a complete notice in accordance with the notification 
    procedure.
    
    [[Page 18957]]
    
        FDA's regulations in part 570 concerning GRAS substances for use in 
    animal food or feeds implement the same statutory provisions as the 
    regulations in part 170 concerning GRAS substances for use in human 
    food. Accordingly, FDA is proposing: (1) To amend the provisions of 
    Sec. 570.30 that are parallel to the provisions of current Sec. 170.30 
    (i.e., Sec. 570.30(a) and (b)); (2) to eliminate the GRAS affirmation 
    petition process provided for in Sec. 570.35(a) and (c); and (3) to 
    provide the option of a GRAS notification procedure for substances used 
    in animal food or feeds that would be parallel to proposed Sec. 170.36.
        FDA is also proposing several amendments to parts 170, 184, 186, 
    and 570 of its regulations as conforming amendments.
    
    XIII. Paperwork Reduction
    
        This proposed rule contains information that is subject to review 
    by OMB under the Paperwork Reduction Act of 1995 (Pub. L. 104-13). 
    Therefore, in accordance with 44 U.S.C. 3506(c)(2)(B) and 5 CFR part 
    1320, FDA is providing below the title, description, and respondent 
    descriptions for the information collections contained in this 
    proposal, along with an estimate of the resulting annual information 
    collection burden. Included in the estimate is the time needed to 
    review instructions, to gather the required information, and to 
    disclose the information.
        FDA invites comments on the following: (1) Whether the proposed 
    collection of information is necessary for the proper performance of 
    the functions of the agency, including whether the information will 
    have practical utility; (2) the accuracy of the agency's estimate of 
    the burden of the proposed collection of information, including the 
    validity of the methodology and assumptions used; (3) ways to enhance 
    the quality, utility, and clarity of the information to be collected; 
    and (4) ways to minimize the burden of the collection of information on 
    those who are to respond, including through the use of automated 
    collection techniques, where appropriate, or other forms of information 
    technology.
        Title: Notice of a Claim for GRAS Exemption Based on a GRAS 
    Determination
        Description: Section 409 of the act establishes a premarket 
    approval requirement for ``food additives;'' section 201(s) of that act 
    provides an exemption from the definition of ``food additive'' and thus 
    from the premarket approval requirement, for uses of substances that 
    are GRAS by qualified experts. FDA is proposing a voluntary procedure 
    whereby members of the food industry who determine that use of a 
    substance satisfies the statutory exemption may notify FDA of that 
    determination. The notice would include a detailed summary of the data 
    and information that support the GRAS determination, and the notifier 
    would maintain a record of such data and information. FDA would make 
    the information describing the GRAS claim, and the agency's response to 
    the notice, available in a publicly accessible file; the entire GRAS 
    notice would be publicly available consistent with the FOIA and other 
    Federal disclosure statutes.
        Description of Respondents: Manufacturers of Substances Used in 
    Food and Feed
        FDA estimates the total annual burden for this information 
    collection to be 9,900 hours.

        There are no operating or maintenance costs or capital costs 
    associated with this collection.
        FDA tentatively concludes that there are no anticipated capital 
    costs or operating and maintenance costs associated with the proposed 
    information collection requirements. However, the agency welcomes 
    comments on any such anticipated costs.
        The agency has submitted copies of the proposed rule to OMB for 
    review of the portions of the proposal that are subject to the 
    Paperwork Reduction Act of 1995. Interested persons are requested to 
    send comments regarding information collection by May 19, 1997 to the 
    Office of Information and Regulatory Affairs, OMB (address above).
    
    XIV. Analysis of Impacts
    
        FDA has examined the impacts of the proposed rule under Executive 
    Order 12866 and the Regulatory Flexibility Act (5 U.S.C. 601-612). 
    Executive Order 12866 directs agencies to assess all costs and benefits 
    of available regulatory alternatives and, when regulation is necessary, 
    to select the regulatory approaches that maximize net benefits 
    (including potential economic, environmental, public health and safety 
    effects; other advantages; distributive impacts; and equity). Executive 
    Order 12866 classifies a rule as significant if it meets any one of a 
    number of specified conditions, including having an annual effect on 
    the economy of $100 million or adversely affecting in a material way a 
    sector of the economy, competition, or jobs, or if it raises novel 
    legal or policy issues. If a rule has a significant economic impact on 
    a
    
    [[Page 18958]]
    
    substantial number of small entities, the Regulatory Flexibility Act 
    requires agencies to analyze regulatory options that would minimize the 
    economic impact of that rule on small entities.
        FDA finds that this proposed rule is not a significant rule as 
    defined by Executive Order 12866, and finds under the Regulatory 
    Flexibility Act that this proposed rule will not have a significant 
    impact on a substantial number of small entities. Finally, FDA, in 
    conjunction with the Administrator of OMB, finds that this proposed 
    rule is not a major rule for the purpose of congressional review (Pub. 
    L. 104-121).
    
    A. Regulatory Options
    
        FDA has the following primary options:
        (1) Take no action;
        (2) Adopt proposed GRAS notification procedure;
        (3) Adopt a GRAS notification procedure allowing FDA feedback on 
    independent GRAS determinations of either a higher or lower level of 
    authoritativeness than the proposed notification system; and
        (4) Eliminate agency participation in independent GRAS 
    determinations.
    
    B. Costs and Benefits
    
    1. Option One: Take No Action
        Neither costs nor benefits are associated with taking no action. 
    This option is the baseline case in comparison with which the costs and 
    benefits of the other options are determined.
        The existing GRAS petition process is a government service provided 
    to industry by which firms may voluntarily submit information to FDA 
    for agency review and affirmation of the GRAS status of the use of a 
    substance in food. Although FDA does not charge a fee to review 
    material submitted under the GRAS petition process, participation in 
    that process is not without cost because the required information must 
    either be generated or gathered, and submitted to FDA. The fact that 
    some firms participate in this voluntary process implies that for some 
    firms, the benefit of participation must be greater than the cost of 
    participation, and also that the net benefit of participation must be 
    greater than the net benefit of existing alternatives, such as private 
    third-party review of independent GRAS determinations. However, the 
    fact that the cost of participation does not reflect the costs involved 
    in actually administering the GRAS petition process means that 
    participation in that process cannot support inferences regarding the 
    net social benefits of the petition process.
        The benefit firms receive from participation in the existing GRAS 
    petition process appears to involve a reduction in the cost of 
    marketing foods containing substances independently determined to be 
    GRAS because FDA affirmation of GRAS status would likely facilitate 
    marketing of such substances. Manufacturers of these foods and retail 
    establishments buying these foods for subsequent resale to consumers 
    may be reluctant to offer them for sale in the absence of assurance 
    that FDA will not subsequently conclude that ingredients independently 
    determined to be GRAS are unapproved food additives. If these 
    substances were subsequently found not to be GRAS, any ensuing seizure 
    of foods containing the unapproved food additive might damage the 
    credibility of those manufacturers and retail establishments, and might 
    lead to economic losses. If there were no process for agency GRAS 
    affirmation, firms making independent GRAS determinations may attempt 
    to substitute for GRAS affirmations by doing additional research, 
    contracting with third party research organizations, or taking other 
    steps to provide adequate assurances to other firms that FDA will 
    probably not subsequently challenge their independent GRAS 
    determinations.
        In addition to providing a desired good or service, the GRAS 
    petition process may result in some benefit in terms of reducing the 
    health risks from substances independently determined to be GRAS if FDA 
    review of the information supporting independent GRAS determinations 
    uncovers an erroneous determination which, if undetected, could lead to 
    health risks.
    2. Option Two: Adopt Proposed GRAS Notification Procedure
        The chief benefit of eliminating the existing GRAS petition process 
    and replacing it with the proposed GRAS notification procedure is that 
    the notification procedure will enable industry to obtain a limited 
    degree of FDA feedback on independent GRAS determinations more quickly 
    and at lower cost, to both industry and FDA, than the GRAS petition 
    process. Under the proposed notification procedure, FDA will determine 
    whether the notice provides a sufficient basis for a GRAS determination 
    or whether information in the notice, or otherwise available to FDA, 
    raises issues that lead the agency to question whether use of the 
    substance is GRAS.
        The proposed notification procedure will come to closure more 
    quickly and generate less uncertainty than the GRAS petition process 
    because the notification procedure is based on a 90-day review period 
    rather than on the open-ended review period of the GRAS petition 
    process. In some cases, the GRAS petition process involves a number of 
    iterative steps in which FDA asks for and receives additional 
    supporting information. Under the notification procedure, FDA will base 
    its response on the notifier's initial submission.
        In addition to the time advantage, the cost of participation in the 
    proposed notification procedure will probably be less than the cost of 
    participation in the GRAS petition process because the notification 
    procedure will require the submission of only a summary of the 
    information used to support the independent GRAS determination, rather 
    than the full supporting information required under the GRAS petition 
    process. For example, the notification procedure will not require the 
    submission of references or material relating to methods of detection 
    in foods, which are required under the GRAS petition process. 
    Submissions under the notification procedure will probably be about 25 
    to 30 pages, while submissions under the current GRAS petition process 
    can have hundreds or even thousands of pages.
        On the other hand, the same underlying information will be required 
    under the notification procedure as under the GRAS petition process, so 
    the potential cost savings will be confined to the relatively modest 
    costs of assembling, copying, and mailing information. The more 
    significant cost of generating or locating the requisite underlying 
    information will not be affected. In addition, the summary required 
    under the proposed notification procedure may fairly be viewed as a 
    step beyond simply providing the supporting information as required 
    under the GRAS petition process. Therefore, although participation in 
    the proposed notification procedure will probably be somewhat less 
    costly than participation in the GRAS petition process, the cost 
    reduction is likely to be relatively modest.
        The primary cost of replacing the existing GRAS petition process 
    with the proposed notification procedure is that it reduces the options 
    available to industry for obtaining FDA feedback on independent GRAS 
    determinations at a level of authoritativeness comparable to that 
    currently offered under the GRAS petition process. Currently, feedback 
    at this level of authoritativeness is available through both the GRAS 
    petition process and the FAP process. The fact that FDA receives both 
    GRAS petitions and FAP's suggests that some
    
    [[Page 18959]]
    
    firms find participation in the GRAS petition process less costly than 
    participation in the FAP process. However, this difference in cost is 
    probably relatively modest because the systems are quite similar. For 
    example, substances that are GRAS may be marketed without prior agency 
    approval and thus may be marketed during the period in which either a 
    GRAS petition or an FAP on that substance is under review.
        The net benefit or cost of the proposed notification procedure will 
    depend largely on whether the value of participation in the proposed 
    notification procedure is or is not comparable to that of participation 
    in the GRAS petition process. If the value of participation in the two 
    systems is roughly comparable, then the time and cost advantages of the 
    proposed notification procedure will probably lead to modest net 
    benefits. However, if participation in the proposed notification 
    procedure is significantly less valuable than participation in the GRAS 
    petition process because of the lower level of authoritativeness of FDA 
    feedback available through the notification procedure, then the 
    proposed procedure could lead to net costs because firms may submit 
    relatively more costly FAP's or take other steps to compensate for the 
    lack of more authoritative FDA feedback on independent GRAS 
    determinations.
    3. Option Three: Adopt a GRAS Notification Procedure Allowing FDA 
    Feedback on Independent GRAS Determinations of Either a Higher or Lower 
    Level of Authoritativeness Than the Proposed Notification System
        The benefits and costs of replacing the existing GRAS petition 
    process with notification procedures allowing FDA feedback on 
    independent GRAS determinations at either higher or lower levels of 
    authoritativeness than the proposed notification procedure are 
    qualitatively similar to the benefits and costs of adopting the 
    proposed notification procedure.
        The net benefits or costs of notification procedures allowing more 
    or less authoritative FDA feedback depend largely on the cost of 
    participation in those systems and the value of the feedback provided 
    to participating firms under those systems. The value of FDA feedback 
    to participating firms involves the degree to which that feedback 
    facilitates the marketing of substances that have been subject to 
    independent GRAS determinations. A system providing more authoritative 
    feedback than the proposed GRAS notification procedure would either 
    require submission of more information or more detailed information, or 
    would involve more detailed agency review of the same amount of 
    information. Thus, participation in such a system would arguably 
    provide more valuable feedback than participation in the proposed 
    notification procedure but would also be more costly than participation 
    in the proposed notification procedure. A system providing less 
    authoritative feedback than the proposed GRAS notification procedure 
    would either require submission of less information or less detailed 
    information, or would involve less detailed agency review of the same 
    amount of information. Thus, participation in such a system would 
    arguably provide less valuable feedback than participation in the 
    proposed notification procedure but would probably also be less costly 
    than participation in the proposed notification procedure.
        In both cases, it is difficult to determine whether the resulting 
    changes in the value of FDA feedback available through the notification 
    procedure would compensate firms for the resulting changes in the cost 
    of participation in such procedures, or to compare the net social 
    benefits of offering such procedures with the net benefits of the 
    existing GRAS petition process.
    4. Option Four: Eliminate Agency Participation in Independent GRAS 
    Determinations
        The costs and benefits of this option are qualitatively similar to 
    those of adopting a notification procedure allowing FDA feedback of 
    only a minimal level of authoritativeness. In general, the same results 
    will occur if the value of participation in a notification procedure 
    drops below the costs involved in participation, or if a notification 
    procedure is not available. In both cases, industry will either submit 
    relatively costly FAP's or take other steps to compensate for the lack 
    of a GRAS notification procedure or petition process, or simply forgo 
    government oversight of their independent GRAS determinations.
        If FDA no longer participates in independent GRAS determinations, 
    FDA will not be aware of substances that have been the subject of 
    independent GRAS determinations unless firms choose to submit FAP's for 
    those substances. Any public health benefits associated with FDA 
    awareness of these substances will be lost. However, if firms take 
    other steps to confirm independent GRAS determinations, then these 
    other steps will be associated with countervailing public health 
    benefits.
        Again, it is difficult to determine whether this option would 
    result in net social costs or benefits because of the difficulty of 
    estimating the value of various levels of FDA and non FDA feedback on 
    independent GRAS determinations. However, the distinctive role of FDA 
    in GRAS issues suggests that FDA feedback may be more valuable to 
    industry than other, equally costly, activity designed to confirm 
    independent GRAS determinations. Therefore, it is likely that the 
    availability of some type of notification procedure will lead to 
    greater net benefits than no notification procedure.
    
    C. Regulatory Flexibility Analysis
    
        The proposed action will affect any firm that may have chosen to 
    participate in the existing GRAS petition process or may choose to 
    participate in the proposed GRAS notification process, including 
    manufacturers of both human and animal food, food additives, and feed 
    additives. The Dun's Market Identifiers database lists 27,989 firms in 
    Standard Industry Code (SIC) 20, Food and Kindred Products. This 
    includes dog and cat food, and prepared feeds not elsewhere classified. 
    In addition, this database lists 113 firms in SIC 2869, Industrial 
    Organic Chemicals, Not Elsewhere Classified, the SIC code that includes 
    manufacturers of food additives. Therefore, a total of 28,102 firms 
    will potentially be affected by this proposed rule.
        The Small Business Administration (SBA) guidelines on the 
    definition of a small business for SIC 20 identify a small business as 
    being a business having no more than 1,000, 750, or 500 employees, 
    depending on the more precise four-digit SIC code associated with the 
    firm in question. However, there is no easy way to distribute the total 
    number of firms in SIC 20 into the appropriate four-digit SIC 
    categories because more than one primary four-digit SIC code may be 
    associated with any given firm. To avoid missing any small firms, the 
    least restrictive size definition of 1,000 or fewer employees was used 
    for all firms. The SBA definition of a small business in SIC 2869 is a 
    business with 1,000 or fewer employees. Based on these definitions, and 
    assuming that the distribution of employment for firms for which no 
    employee data are available is the same as the distribution for firms 
    for which data are available, a total of 27,531 firms could potentially 
    be affected by this proposed rule.
    
    [[Page 18960]]
    
        Although this proposal may affect a substantial number of firms 
    that manufacture food or food additives, many of which are small firms, 
    this proposal will not have a significant impact on these firms for two 
    reasons. First, this proposal replaces one voluntary program with 
    another voluntary program. Therefore, small firms will not be required 
    to undertake any additional activity or bear any additional costs. 
    Second, participation in the proposed GRAS notification procedure 
    should be somewhat less costly than participation in the GRAS petition 
    process. Therefore, small firms should be better able to participate in 
    the notification procedure than the petition process.
    
    D. Conclusions
    
        In accordance with Executive Order 12866, FDA has analyzed this 
    proposed rule and finds that this proposed rule is neither economically 
    significant nor a significant action, as defined by that order. FDA has 
    also analyzed this proposed rule in accordance with the Regulatory 
    Flexibility Act and finds that this proposed rule will not have a 
    significant impact on a substantial number of small businesses. 
    Accordingly, under the Regulatory Flexibility Act, 5 U.S.C. 605(b), the 
    Commissioner certifies that this proposed rule will not have a 
    significant economic impact on a substantial number of small entities.
        The net costs and benefits of replacing the GRAS petition process 
    with the proposed GRAS notification procedure are indeterminate. 
    However, any increase in net costs or benefits relative to the current 
    system will probably be modest. FDA requests comments on the costs and 
    benefits of replacing the GRAS petition process with the proposed GRAS 
    notification procedure.
    
    XV. Environmental Impact
    
        The agency has determined under 21 CFR 25.24(a)(8) that this action 
    is of a type that does not individually or cumulatively have a 
    significant effect on the human environment. Therefore, neither an 
    environmental assessment nor an environmental impact statement is 
    required.

        5. New Sec. 170.36 is added to subpart B to read as follows:
    
    
    Sec. 170.36  Notice of a claim for exemption based on a GRAS 
    determination.
    
        (a)(1) Any person may notify FDA of a claim that a particular use 
    of a substance is exempt from the statutory premarket approval 
    requirements based on the notifier's determination that such use is 
    generally recognized as safe (GRAS).
        (2) Notice to the agency of this section shall not constitute 
    compliance with:
        (i) Section 101.14(b)(3)(ii) of this chapter. Any person who 
    submits a health claim petition under Sec. 101.14 of this chapter shall 
    comply in full with Sec. 101.14(b)(3)(ii) regardless of whether
    
    [[Page 18961]]
    
    the agency has been notified under this section about a substance and 
    regardless of the nature of the agency's response.
        (ii) Section 106.120(b)(6)(ii) of this chapter. Any person who 
    submits a new infant formula submission under proposed Sec. 106.120 of

    regardless of whether the agency has been notified under this section 
    about a substance and regardless of the nature of the agency's 
    response.
        (b) A notice of a GRAS exemption claim shall be submitted in 
    triplicate to the Office of Premarket Approval (HFS-200), Center for 
    Food Safety and Applied Nutrition, Food and Drug Administration, 200 C 
    St. SW., Washington, DC 20204.
        (c) Notifiers shall submit the following information:
        (1) A claim, dated and signed by the notifier, or by the notifier's 
    attorney or agent, or (if the notifier is a corporation) by an 
    authorized official, that a particular use of a substance is exempt 
    from the premarket approval requirements of the Federal Food, Drug, and 
    Cosmetic Act (the act) because the notifier has determined that such 
    use is GRAS. Such GRAS exemption claim shall include:
        (i) The name and address of the notifier;
        (ii) The common or usual name of the substance that is the subject 
    of the GRAS exemption claim (i.e., the ``notified substance'');
        (iii) The applicable conditions of use of the notified substance, 
    including the foods in which the substance is to be used, levels of use 
    in such foods, and the purposes for which the substance is used, 
    including, when appropriate, a description of the population expected 
    to consume the substance;
        (iv) The basis for the GRAS determination (i.e., through scientific 
    procedures or through experience based on common use in food); and
        (v) A statement that the data and information that are the basis 
    for the notifier's GRAS determination are available for the Food and 
    Drug Administration's (FDA) review and copying at reasonable times at a 
    specific address set out in the notice or will be sent to FDA upon 
    request.
        (2) Detailed information about the identity of the notified 
    substance, including, as applicable, its chemical name, Chemical 
    Abstracts Service (CAS) Registry Number, Enzyme Commission number, 
    empirical formula, structural formula, quantitative composition, method 
    of manufacture (excluding any trade secrets and including, for 
    substances of natural biological origin, source information such as 
    genus and species), characteristic properties, any content of potential 
    human toxicants, and specifications for food-grade material;
        (3) Information on any self-limiting levels of use; and
        (4) A detailed summary of the basis for the notifier's 
    determination that a particular use of the notified substance is exempt 
    from the premarket approval requirements of the act because such use is 
    GRAS. Such determination may be based either on scientific procedures 
    or on common use in food.
        (i) For a GRAS determination through scientific procedures, such 
    summary shall include:
        (A) A comprehensive discussion of, and citations to, generally 
    available and accepted scientific data, information, methods, or 
    principles that the notifier relies on to establish safety, including a 
    consideration of the probable consumption of the substance and the 
    probable consumption of any substance formed in or on food because of 
    its use and the cumulative effect of the substance in the diet, taking 
    into account any chemically or pharmacologically related substances in 
    such diet;
        (B) A comprehensive discussion of any reports of investigations or 
    other information that may appear to be inconsistent with the GRAS 
    determination; and
        (C) The basis for concluding, in light of the data and information 
    described under paragraphs (c)(1), (c)(2), (c)(3), (c)(4)(i)(A), and 
    (c)(4)(i)(B) of this section, that there is consensus among experts 
    qualified by scientific training and experience to evaluate the safety 
    of substances added to food that there is reasonable certainty that the 
    substance is not harmful under the intended conditions of use.
        (ii) For a GRAS determination through experience based on common 
    use in food, such summary shall include:
        (A) A comprehensive discussion of, and citations to, generally 
    available data and information that the notifier relies on to establish 
    safety, including evidence of a substantial history of consumption of 
    the substance by a significant number of consumers;
        (B) A comprehensive discussion of any reports of investigations or 
    other information that may appear to be inconsistent with the GRAS 
    determination;
        (C) The basis for concluding, in light of the data and information 
    described under paragraphs (c)(1), (c)(2), (c)(3), (c)(4)(ii)(A), and 
    (c)(4)(ii)(B) of this section, that there is consensus among experts 
    qualified by scientific training and experience to evaluate the safety 
    of substances added to food that there is reasonable certainty that the 
    substance is not harmful under the intended conditions of use.
        (d) Within 30 days of receipt of the notice, FDA shall acknowledge 
    receipt of a notice by informing the notifier in writing of the date on 
    which the notice was received.
        (e) Within 90 days of receipt of the notice, FDA shall respond to 
    the notifier in writing.
        (f)(1) Any GRAS exemption claim submitted under paragraph (c)(1) of 
    this section shall be immediately available for public disclosure on 
    the date the notice is received. All remaining data and information in 
    the notice shall be available for public disclosure, in accordance with 
    part 20 of this chapter, on the date the notice is received.
        (2) For each GRAS notice submitted under this section, the 
    following information shall be readily accessible for public review and 
    copying:
        (i) A copy of the GRAS exemption claim submitted under paragraph 
    (c)(1) of this section.
