# SUPPLEMENTARY INFORMATION:

PHMSA received a special permit request from Rockies Express Pipeline, LLC (REX), a subsidiary Tallgrass Energy, on January 8, 2024, seeking a special permit to deviate from the Federal pipeline safety regulations in 49 CFR 192.179(a)(4), which requires transmission line valves to be placed no further than 10 miles apart in a Class 1 location. The special permit request is for a single segment where the valves are spaced 20.35 miles apart, exceeding the valve spacing requirement by 924 feet.

The proposed special permit would allow REX to continue to operate the single  20.35-mile segment of 42-inch diameter gas transmission pipeline without modifying the valve location. The 20.35-mile segment is in a Class 1 location in Monroe and Belmont Counties, Ohio.

The special permit request, proposed special permit with conditions, and Draft Environmental Assessment (DEA)/FONSI for the above listed REX pipeline segment are available for review and public comments in Docket Number PHMSA 2024-0011. PHMSA invites interested persons to review and submit comments on the special permit request and DEA/FONSI in the docket. Please submit comments on any potential safety, environmental, and other relevant considerations implicated by the special permit request. 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.

Issued in Washington, DC, on October 23, 2024, under authority delegated in 49 CFR 1.97.

Alan K. Mayberry,

Associate Administrator for Pipeline Safety.
