Section 211.19 - Petitions for extensions of time to comment(a) Any person may petition the Administrator for an extension of time to submit comments in response to an advance notice or notice of proposed rulemaking. The petition must be received by the FRA Docket Clerk not later than 10 days before expiration of the time stated in the notice and must contain reference to the FRA docket number for the proceeding involved. The filing of the petition does not automatically extend the time for petitioner's comments.(b) The Administrator grants the petition only if the petitioner shows a substantive interest in the proposed rule and good cause for the extension, and if time permits and the extension is in the public interest. Extensions will not be granted unless time permits and will not exceed one month. If an extension is granted, it is granted as to all persons and a notice of the extension is published in the FEDERAL REGISTER.41 FR 54181, Dec. 13, 1976, as amended at 64 FR 70195, Dec. 16, 1999
