Notice Text:

SEGMENT 13 – AMARILLO #3 M/L – INSTALL LAUNCHER/RECEIVER – CS 107 – UPDATE #5

 

The scheduling percentage has been increased, as noted below.  This notice was last posted on September 3, 2020, entitled “SEGMENT 13 – AMARILLO #3 M/L – INSTALL LAUNCHER/RECEIVER – CS 107 – UPDATE #4”.

 

As previously posted on Natural's Outage Impact Report, on the dates noted below, Natural will be performing pipeline maintenance to install pigging facilities on the Amarillo #3 mainline near Compressor Station 107 (CS 107) located in Mills County, Iowa (Segment 13 of Natural's Amarillo Mainline Zone).  This maintenance work will require Natural to temporarily reduce the operating capacity, thus limiting Natural's throughput capacity northbound through CS 107.

 

The transport scheduling constraint will be at CS 107; therefore, any gas received south of CS 107 for delivery north of CS 107 will be impacted for the duration of the outage.  Additionally, transports associated with storage injections will be impacted.  For scheduling purposes, the Amarillo Mainline Pool (LOC 10566) is located south of the constraint.

 

On the dates listed below, Natural will schedule Primary Firm and Secondary in-path Firm transports to no less than 55% of contract MDQ (previously 51%) through CS 107.  Receipts and deliveries at Northern Natural Mills (LOC 900203) will be available for the duration of the outage.

 

INSTALL DATES:

 

Gas day Wednesday, September 9, 2020, and continuing through gas day Sunday, September 20, 2020.  The scheduling percentage increase will be effective for gas day Saturday, September 12, 2020, Evening Cycle, and continuing through gas day Sunday, September 20, 2020.

 

Actual nomination levels and changes in pipeline conditions could result in changes to the percentages scheduled (lower or higher) on subsequent gas days.  AOR/ITS and Secondary out-of-path Firm transports will not be available.

 

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.

 

Continue to monitor Natural's interactive website for any updates to the end date and/or scheduling percentages during this outage.
