SUPPLEMENTARY INFORMATION:

PHMSA received a special permit request from ETNG, owned and operated by Enbridge Inc., seeking a waiver from the requirements of 49 CFR 192.53(c), 192.121, 192.144, 192.149, 192.150, 192.619(a), 192.624, 192.710, and 192.714, for the use of composite pipe (Smartpipe®) and fittings to replace approximately 0.64 miles of an interstate gas transmission pipeline located in a Class 3 location in Roanoke County, Virginia. Smartpipe® is a flexible reinforced thermoplastic pipe that is not authorized by 49 CFR part 192. ETNG proposes to insert the Smartpipe®, 6-inch inside diameter and 7.6-inch outside diameter, into the existing 8.625-inch outside diameter steel pipeline, known as ETNG's Line No. 3320A-100 Pipeline. ETNG's request proposes the pipe pulling tensile force would be limited to 40,000 pounds during installation of the Smartpipe®, which is 44 percent of the Smartpipe® rating of 90,000 pounds. The request also proposes that the Line No. 3320A-100 Pipeline would have a maximum allowable operating pressure of 813 pounds per square inch gauge after installation of the Smartpipe®. The existing Line No. 3320A-100 Pipeline is externally coated with coal tar enamel.

The special permit request, proposed special permit with conditions, and draft environmental assessment (DEA) for the ETNG Line No. 3320A-100 Pipeline are available for review and public comment in the Docket No. PHMSA-2022-0167. PHMSA invites interested persons to review and submit comments on the special permit request, proposed special permit with conditions, and DEA in the docket. Please include any comments on potential safety and environmental impacts that may result if the special permit is granted. Comments may include relevant data.

Before issuing a decision on the special permit requests, PHMSA will evaluate all comments received on or before the comment closing date. Comments received after the closing date will be evaluated, if it is possible to do so without incurring additional expense or delay. PHMSA will consider each relevant comment it receives in making its decision to grant or deny this request.

Issued in Washington, DC, on December 28, 2022, under authority delegated in 49 CFR 1.97.

Associate Administrator for Pipeline Safety.
