Notice Text:

STATION 302 – REPLACE REGULATOR – UPDATE

SEGMENT 11 – AMARILLO #3 M/L – CS 105/106 – ILI TOOL RUNS – UPDATE 1

Update to indicate Midcontinent Pool is impacted south of constraint instead of Amarillo Pool. See previous notice ID 46806 dated March 5, 2026.

As previously posted on Natural's Outage Impact Report (X25-1240570) and as part of Natural's ongoing pipeline Integrity Management Program, Natural will perform a series of ILI tool runs on its Amarillo #3 mainline between Compressor Station 105 (CS 105) located in Cloud County, Kansas and Compressor Station 106 (CS 106) located in Gage County, Nebraska (Segment 11 of Natural's Midcontinent Zone). The tool runs will require Natural to reduce the operating capacity, thus limiting Natural's throughput capacity northbound through CS 106. Once the data from the tool runs have been analyzed, any remediation work impacting shippers will be posted.

The scheduling constraint will be at CS 106; therefore, any gas received south of CS 106 for delivery north of CS 106 will be impacted for the duration of the restriction. Receipts from Trailblazer Gage (LOC 902900) are north of CS 106 and will not be impacted. For scheduling purposes, the Midcontinent Pool (LOC 25078) is located south of the constraint. Additionally, firm transportation associated with storage withdrawals or injections may be impacted.

As such, effective on the gas days indicated below, Natural will schedule Primary Firm and Secondary in-path Firm transports to no less than 60% of contract MDQ northbound through CS 106. AOR/ITS and Secondary out-of-path Firm transports will not be available for the duration of the restriction.

TOOL RUN DATES:

Gas day Tuesday, April 21, 2026 (Cleaning/ Gauge Tools)

Gas day Thursday, April 23, 2026 (Cleaning Tool)

Gas day Tuesday, April 28, 2026 (MFL Tool)

The stated scheduling percentage is based upon the current level of firm capacity contracted for during this restriction and is subject to change based upon operational conditions and Shipper utilization.

Continue to monitor Natural's interactive website for any updates to the end date and/or scheduling percentage during this restriction. Please contact your Account Director or Scheduling Representative if you have any questions.
