End Further Info End Preamble Start Supplemental Information


PHMSA received a special permit renewal request from Tennessee Gas Pipeline Company (TGP), owned by Kinder Morgan Inc., to continue its pipeline operation as defined in the special permit renewal issued on May 15, 2015. An additional 200 feet of pipeline, where the Class location had changed from Class 1 to 3, was added to the special permit segment 3 on March 28, 2017. The present special permit term is through May 15, 2020. TGP's special permit renewal request of November 12, 2019, seeks to waive compliance from the requirements of 49 CFR 192.611, “Change in class location: Confirmation or revision of maximum allowable operating pressure”. This special permit renewal is being requested in lieu of pipe replacement or pressure reduction for four (4) special permit segments totaling 37,731 feet of either 30-inch diameter Line 800-1, 30-inch diameter Line 500-1, 36-inch diameter Line 500-2, or 36-inch diameter Line 500-3 located in Dickson and Hickman Counties, Tennessee. The special permit renewal will allow the continued operation of the original Class 1 pipe in the Class 3 locations.

The TGP Line 800-1, Line 500-1, Line 500-2, and Line 500-3 have a maximum allowable operating pressure of 936 pounds per square inch gauge in the special permit segments.

The special permit renewal request, existing special permit with conditions, and environmental assessment (EA) for the TGP is available for review and public comment in the Docket No. PHMSA-RSPA-2000-8453. We invite interested persons to review and submit comments on the special permit renewal request and EA in the docket. Please include any comments on potential safety and environmental impacts that may result if the special permit renewal is granted. Comments may include relevant data.

Before issuing a decision on the special permit renewal 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 this special permit renewal request.
