SEGMENT 26 – GULF COAST #3 M/L - ILI TOOL RUNS – UPDATE 1
The Tool run dates have changed. See previous Notice ID 46857 dated April 2, 2026
As previously posted on Natural's Outage Impact Report (X25-1474603 and X25-147896) and as part of Natural's ongoing pipeline Integrity Management Program, Natural will perform a series of ILI tool runs on the Gulf Coast #3 Mainline near Compressor Station 394 (CS 394) located in Cass County, Texas, in Segment 26 of Natural's Texok Zone. Natural previously anticipated no customer impact during this pipeline integrity maintenance work at CS 394. However, due to current operational conditions and to maintain system integrity, the scope of the project has been changed and will now impact the receipt locations as noted below. Once the data from the tool runs have been analyzed, any remediation work impacting shippers will be posted.
As such, effective on the gas days indicated below, the receipt locations listed below will be shut in for the duration of this integrity work. No transport services will be available.
