# SUPPLEMENTARY INFORMATION:

PHMSA received a special permit request from STT, a joint venture between Spectra Energy Partners, LP (Enbridge), NextEra Energy, Inc., and Duke Energy, which is operated by Enbridge Inc., seeking a waiver from the requirements of 49 CFR 192.611: Change in class location: Confirmation or revision of maximum allowable operating pressure. This special permit is being requested in lieu of pipe replacement or pressure reduction for one (1) special permit segment totaling 53,486 feet (approximately 10.130 miles) on the STT Line 1 Pipeline. The proposed special permit segment is located in Sumter County, Florida. The STT Line 1 Pipeline class location in the special permit segment has changed from a Class 1 to a Class 3 location. The STT Line 1 Pipeline special permit segment is a 36-inch diameter pipeline with an existing maximum allowable operating pressure of 1,456 pounds per square inch gauge. The installation of the special permit segment occurred in 2017.

                    The special permit request, proposed special permit with conditions, and Draft Environmental Assessment (DEA) for the above listed STT pipeline segments are available for review and public comments in Docket No. PHMSA-2021-0052. PHMSA invites interested persons to review and submit comments on the special permit request and DEA in the docket. Please include any comments on potential safety and                           ( print page 47735)                        environmental impacts that may result if the special permit is granted. Comments may include relevant data.                

Before issuing a decision on the special permit request, PHMSA will evaluate all comments received on or before the comments 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 special permit request.
