Notice Text:



The project dates have been changed, as noted below.  This notice was last posted on August 26, 2021, entitled “PIPELINE MAINTENANCE – COMPRESSOR STATION 343/342 – UPDATE #2”.


As previously posted on Natural's Outage Impact Report (X19-1077708), Natural will be performing pipeline maintenance work on its Louisiana #1 line between Compressor Station 343 (CS 343) located in Liberty County, Texas and Compressor Station 342 (CS 342) located in Cameron Parish, Louisiana (Segment 23 of Natural's Louisiana Zone).  During this outage, Natural is required to temporarily reduce the maximum operating capacity into Segment 25 thus limiting Natural's throughput capacity eastbound through CS 343.


The scheduling constraint will be at CS 302 (Segment 25); therefore, any gas received west of CS 302 for delivery east of CS 302 from Segment 26 or Segment 22 will be impacted for the duration of the outage.  The Pooling Point - Texok Zone (LOC 10560) is located west of the constraint.  Transportation associated with storage injections or withdrawals may be impacted.


As such, effective for gas day Wednesday, September 22, 2021, Timely Cycle, and continuing through gas day Monday, September 27, 2021 (previously Thursday, September 16, 2021 thru Tuesday, September 21, 2021), Natural will schedule Primary Firm and Secondary in-path Firm transports, only, through CS 302 (Segment 25).  AOR/ITS and Secondary out-of-path Firm transports will not be available for the duration of this outage.


Continue to monitor Natural's interactive website for any updates during this outage.  Please contact your Account Director or Scheduling Representative if you have any questions.
