PHMSA received a special permit request from Gulf South Pipeline Company, LP, (“GSPC”) to deviate from the pipeline safety regulations in 49 CFR 192.611, for four segments totaling 4.65 miles, of 30-inch diameter Index 130 pipeline, located in Ascension and Livingston Parishes, Louisiana, where the class location has changed from a Class 1 to Class 3 location. In lieu of pipe replacement, GSPC seeks permission to perform alternative risk control activities based on integrity management program principles and requirements. Due to class location changes from a Class 1 to Class 3 in the 1990s, GSPC lowered the maximum allowable operating pressure as required by § 192.611, from 936 pounds per square inch gauge (psig) to 780 psig. However, GSPC now seeks to uprate the line to restore the previous MAOP, using Subpart K of § 192.555.

The special permit request provided by the operator includes a draft environmental assessment, (EA), proposed special permit conditions, and location map. These documents are filed at, in Docket No. PHMSA-2018-0099. We invite interested persons to participate by reviewing the special permit documents and draft EA at, 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 comment 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.
