SEGMENT 25 – LOUISIANA #1 LINE – PIPE REPLACEMENT
Natural will be performing pipeline replacement on its Louisiana #1 Line between Compressor Station 302 (CS 302) located in Montgomery County, Texas and the Trinity River located in Liberty County, Texas. Natural is required to reduce the maximum operating capacity eastbound into Segment 25 from Segment 26 and Segment 22, thus limiting Natural's throughput capacity eastbound through CS 302 during this restriction. This maintenance work will be performed in four phases as noted below. The Pooling Point - Texok Zone (LOC 10560) is located west of the constraint. Firm transportation associated with storage injections or withdrawals may be impacted. During each phase of the maintenance work shown below, the scheduling constraint will be at CS 302.
PHASE 1
As posted on Natural's Outage Impact Report (X25-366541), Phase 1 will begin on gas day Friday, October 31, 2025, Timely Cycle, and continue through gas day Monday, November 3, 2025. During this phase, Natural will schedule Primary Firm and Secondary in-path Firm transports to no less than 71% of contract MDQ.

During this phase, Natural will schedule Primary Firm and Secondary in-path Firm transports to no less than 85% of contract MDQ.
The stated scheduling percentage is based upon the current level of firm capacity contracted for during this outage and is subject to change based upon operational conditions and Shipper utilization.
