Docket No. 97N-0103

Substances Generally Recognized as Safe

AGENCY: Food and Drug Administration, HHS.

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.

ADDRESSES: Submit written comments to the Dockets Management Branch

(HFA-305), Food and Drug Administration, 12420 Parklawn Dr., rm. 1-23,

Rockville, MD 20857. Submit written comments on the information

collection requirements to the Office of Information and Regulatory

Affairs, Office of Management and Budget (OMB), New Executive Office

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.<SUP>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 ``safety 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:

substantial 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, ``strategies 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), ``safety evaluation of foods produced by modern

biotechnology: Concepts and principles'' (Ref. 8); and a report of a

WHO workshop, ``application 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. <SUP>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.<SUP>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.<SUP>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,

<SUP>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.

---------------------------------------------------------------------------

<SUP>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.

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.
