SUPPLEMENTARY INFORMATION: On February 27, 2009, PHMSA issued a special permit (PHMSA-2007-0039) to Gulf South Pipeline Company (GSPC) for the 30-inch diameter transmission pipeline (TPL-880) pipeline located in Mobile County, Alabama. Due to several Class 1 to Class 3 location change of several areas within a 10.8-mile segment on the TPL-880 pipeline, GSPC petitioned PHMSA for an extension of the previously issued special permit.
The line transports natural gas from the Gulf of Mexico to other pipelines located in Alabama. The special permit inspection area includes 22 miles of the TPL-880 pipeline, extending from the beginning of the line at Station Number 0+00 to the pig trap at Airport Compressor Station Number 1201+68. The new permit request is located within the existing inspection area of Special Permit PHMSA-2007-0039, extends from Station Number 632+60 to Station Number 1201+68, is 10.8 miles long, and is in a suburban area of farm, pasture, and woodland. The current maximum allowable operation pressure (MAOP) for the TPL-880 is 1,073 psig. In the special permit request, GSPC seeks to waive compliance from the requirements of 49 CFR 192.611(a), which requires the pressure reduction, pressure testing, or pipe replacements to address class location changes when the MAOP of a segment of pipeline is not commensurate with the new class location. Condition #26 of the existing special permit PHMSA-2007-0039, allows extensions of the original special permit segments to include contiguous segments of the TPL-880 pipeline up to the limits of the special permit inspection area. GSPC requests one special permit to extend over all three existing special permit segments located on the TPL-880 in Mobile County, Alabama, where the class location has changed from Class 1 to Class 3, and to include additional areas that may experience further development and class change in the future. As described in this application, GSPC proposes to apply alternative risk control measures to the 10.8-mile segment of TPL-880 to provide an acceptable margin of safety and environmental protection to meet the requirements of Sec. 192.611, as outlined in the proposed special permit conditions.
A combined Draft Environmental Assessment (DEA) and proposed Finding of No Significant Impact (FONSI), proposed special permit conditions, and supporting documentation are available at http://www.Regulations.gov, in Docket Number, PHMSA-2007-0039. We invite interested persons to participate by reviewing the special permit request, DEA and proposed FONSI documents at http://www.Regulations.gov, 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 at the close of the comment period. Comments received after the close of the comment period 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.
Issued in Washington, DC, on March 20, 2018, under authority delegated in 49 CFR 1.97.
