PHMSA has received a special permit request from the National Fuel Gas Supply Corporation (NFG), to deviate from the federal pipeline safety regulations at 49 CFR 192.53, 192.55, 192.105, 192.107, 192.109, 192.111, 192.113, 192.144, 192.149, 192.150, 192.327, 192.463, and 192.619, for the use of FlexSteel pipe and fittings in a regulated interstate gas transmission pipeline in Class 1 and Class 2 locations. NFG proposes to insert a 6-inch diameter FlexSteel pipe, 5.60-inch inside diameter and 7.05-inch outside diameter, into an existing 12.75-inch outside diameter pipeline. The 6-inch diameter FlexSteel pipe will have a maximum allowable operating pressure of 720 pounds per square inch gauge (psig). NFG proposes to install the FlexSteel pipe into approximately 5.8 miles of an existing 12.75-inch outside diameter bare steel pipeline known as the FM120 pipeline located in McKean and Elk Counties in Pennsylvania. FlexSteel is pipe comprised of high-density polyethylene PE47 10 inner and outer layers with a steel middle layer. The FlexSteel pipe will have a rating of 1,500 psig, empty weight of 12.9 pounds per foot, maximum pipe operating temperature of 150 degrees Fahrenheit, and maximum installation tension of 30,000 pounds.

A Draft Environmental Assessment (DEA) and Proposed Finding of No Significant Impact (FONSI) with proposed special permit conditions are available for comment at, in Docket Number PHMSA-2017-0090. We invite interested persons to participate by reviewing the special permit request, DEA, and proposed FONSI, and by submitting written comments, data, or other views. Please include any comments on potential safety and environmental impacts that may result if the special permit is granted.

Before issuing a decision on the special permit request, 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 we receive, in making our decision to grant or deny a request.
