§ 570.35 Affirmation of generally recognized as safe （GRAS） status.
（a） The Commissioner, either on his initiative or on the petition of an interested person, may affirm the GRAS status of substances that directly or indirectly become components of food.
（b）（1） If the Commissioner proposes on his own initiative that a substance is entitled to affirmation as GRAS, he will place all of the data and information on which he relies on public file in the office of the Division of Dockets Management and will publish in the Federal Register a notice giving the name of the substance, its proposed uses, and any limitations proposed for purposes other than safety.
（2） The Federal Register notice will allow a period of 60 days during which any interested person may review the data and information and/or file comments with the Division of Dockets Management. Copies of all comments received shall be made available for examination in the Division of Dockets Management's office.
（3） The Commissioner will evaluate all comments received. If he concludes that there is convincing evidence that the substance is GRAS as defined in §570.3（k）, he will publish a notice in the Federal Register listing the substance in this subchapter E as GRAS.
（4） If, after evaluation of the comments, the Commissioner concludes that there is a lack of convincing evidence that the substance is GRAS and that it should be considered a food additive subject to section 409 of the act, he shall publish a notice thereof in the Federal Register in accordance with §570.38.
（c）（1） Persons seeking the affirmation of GRAS status of substances as provided for in §570.30（e）, except those subject to the NAS-NRC GRAS list survey （36 FR 20546）, shall submit a petition for GRAS affirmation pursuant to part 10 of this chapter.

Any adverse information or consumer complaints shall be included. Complete bibliographic references shall be provided where a copy of the article is not provided.
（v） A statement signed by the person responsible for the petition that to the best of his knowledge it is a representative and balanced submission that includes unfavorable information, as well as favorable information, known to him pertinent to the evaluation of the safety and functionality of the substance.
（vi） If nonclinical laboratory studies are involved, additional information and data submitted in support of filed petitions shall include, with respect to each nonclinical study, either a statement that the study was conducted in compliance with the requirements set forth in part 58 of this chapter, or, if the study was not conducted in compliance with such regulations, a brief statement of the reason for the noncompliance.
（vii） [Reserved]
（viii） A claim for categorical exclusion under §25.30 or 25.32 of this chapter or an environmental assessment under §25.40 of this chapter.
（2） Within 30 days after the date of filing the petition, the Commissioner will place the petition on public file in the Division of Dockets Management and will publish a notice of filing in the Federal Register giving the name of the petitioner and a brief description of the petition including the name of the substance, its proposed use, and any limitations proposed for reasons other than safety. A copy of the notice will be mailed to the petitioner at the time the original is sent to the Federal Register .
（3） The notice of filing in the Federal Register will allow a period of 60 days during which any interested person may review the petition and/or file comments with the Division of Dockets Management. Copies of all comments received shall be made available for examination in the Division of Dockets Management.
（4） The Commissioner will evaluate the petition and all available information including all comments received. If the petition and such information provide convincing evidence that the substance is GRAS as defined in §570.3, he will publish an order in the Federal Register listing the substance in this subchapter E as GRAS.
（5） If, after evaluation of the petition and all available information, the Commissioner concludes that there is a lack of convincing evidence that the substance is GRAS and that it should be considered a food additive subject to section 409 of the act, he shall publish a notice thereof in the Federal Register in accordance with §570.38.
（6） The notice of filing in the Federal Register will request submission of proof of any applicable prior sanction for use of the ingredient under conditions different from those proposed to be determined to be GRAS. The failure of any person to come forward with proof of such an applicable prior sanction in response to the notice of filing will constitute a waiver of the right to assert or rely on such sanction at any later time. The notice of filing will also constitute a proposal to establish a regulation under this subchapter E, incorporating the same provisions, in the event that such a regulation is determined to be appropriate as a result of submission of proof of such an applicable prior sanction in response to the notice of filing.
