SUPPLEMENTARY INFORMATION:
PHMSA received a special permit request from Natural Gas Pipeline Company of America, LLC (NGPL), a subsidiary of Kinder Morgan, Inc, on August 29, 2024 seeking to deviate from the Federal pipeline safety regulations in 49 CFR 192.611 and 192.619, for 16 special permit segments (SPSs) which include 54,744 feet (approximately 10.37 miles) of the NGPL natural gas transmission pipeline system named Louisiana Line #2 located in Montgomery, Harris, and Liberty counties, Texas.
Due to class location changes from Class 1 to Class 3 in 2007, NGPL lowered the maximum allowable operating pressure (MAOP) as required by 49 CFR 192.611, from 1,100 pounds per square inch gauge (psig) to 936 psig. However, NGPL now seeks to increase the pressure on the line to restore the previous MAOP using 49 CFR 192.555.
NPGL has taken proactive measures in consultation with PHMSA to assess integrity of the line and maintain pipeline and public safety including:
• In 2023, NGPL completed in-line inspection (ILI) of the entire special permit inspection area with caliper, inertial measurement unit, and magnetic flux leakage-axial (MFL-A). All MFL-A and deformation ILI inspections were performed using high resolution metal loss and slope deformation tools.
• The SPSs and overall SPIA have been pressure tested to at least 90 percent specified minimum yield strength (SMYS) and 1.25 times MAOP as recently as 2024. Some portions were taken to a level of 1.39 times MAOP or 100 percent SMYS.
The draft conditions were preliminarily determined to ensure the special permit is not inconsistent with pipeline safety. The requested SPSs are as follows:

PHMSA invites interested persons to review and submit comments in the docket on the special permit request, draft proposed special permit with attachments, and DEA. 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 comment closing date.
