On December 17, 1970, the Department of Transportation issued a notice of proposed rule making (35 F.R. 19521, Dec. 23, 1970) proposing procedural rules for gas pipeline regulations. The date for return of comments was set as January 29, 1971. Due to the holiday season, the mailing of copies of this proposal to the Office of Pipeline Safety mailing list was delayed more than had been anticipated. As a consequence, many persons may not have adequate time to prepare and submit comments before the prescribed date. Therefore, the date for submission of comments on Notice 70-14 Is extended to February 18, 1971. Interested persons are also requested to note that the docket for this rule making proceeding has been changed to Docket No. OPS-7.
