As part of its required ongoing pipeline integrity Management Program, on gas day Tuesday, March 26, 2019, and continuing through gas day Thursday, April 11, 2019, Natural will perform an ILI tool run on the Gulf Coast #2 mainline between Compressor Station 300 located in Victoria County, Texas and Compressor Station 341 located in Nueces County, Texas (Segments 22 and 20 of Natural's South Texas Zone). This tool run will require Natural to schedule Primary Firm and Secondary in-path Firm transports, only, southbound into Segment 22 for the duration of this tool run. AOR/ITS and Secondary out-of-path Firm transports will not be available.
SEGMENT 26 SOUTHBOUND – STATION MAINTENANCE – CS 303
On gas day Tuesday, March 26, 2019, and continuing through gas day Monday, April 1, 2019, Natural will be performing station maintenance at Compressor Station 303, located in Angelina County, Texas (Segment 26 of Natural's Texok Zone). This work will require Natural to schedule Primary Firm and Secondary in-path Firm transports, only, southbound through Compressor Station 302 located in Montgomery County, Texas for the duration of this maintenance project. AOR/ITS and Secondary out-of-path Firm transports will not be available during this work. Additionally, Primary Firm and Secondary in-path Firm transports may also be at risk of not being fully scheduled.
The following projects will begin April 2019:
SEGMENT 22 – GULF COAST #2 (CS 301/300) – ILI TOOL RUN
As part of its required ongoing pipeline integrity Management Program, on gas day Tuesday, April 9, 2019, and continuing through gas day Tuesday, April 16, 2019, Natural will perform an ILI tool run on the Gulf Coast #2 mainline between Compressor Station 301 located in Wharton County, Texas and Compressor Station 300 located in Victoria County, Texas (Segment 22 Natural's South Texas Zone). This tool run will require Natural to schedule Primary Firm and Secondary in-path Firm transports, only, southbound into Segment 22 for the duration of this tool run. AOR/ITS and Secondary out-of-path Firm transports will not be available.
SEGMENT 11 – ILI TOOL RUNS
Natural will perform a series of ILI tool runs on the Amarillo #3 mainline between Compressor Station 104 (CS 104) located in Barton County, Kansas and Compressor Station 105 (CS 105) located in Cloud County, Kansas (Segment 11 of Natural's Midcontinent Zone). As a result, Natural is required to temporarily reduce the maximum operating capacity in the affected area. This restriction will limit Natural's throughput capacity northbound through CS 104 and CS 105.
The scheduling constraint will be at CS 105; therefore, any gas received south of CS 105 for delivery north of CS 105 will be impacted for the duration of this restriction. For scheduling purposes, the Midcontinent Pool (LOC 25078) is located south (upstream) of the constraint. Additionally, transports associated with storage withdrawals will also be impacted. Any supply points north (downstream) of CS 105 will not be impacted by this restriction.
As such, on the gas days listed below, Natural will schedule Primary Firm and Secondary in-path Firm transports to no less than 38% of contract MDQ through CS 105 during these tool runs. 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.
Gas Days Impacted:
Tuesday, April 9, 2019
Thursday, April 11, 2019
Tuesday, April 16, 2019
Tuesday, April 23, 2019
Thursday, April 25, 2019
The stated scheduling percentage is based upon the current level of firm capacity contracted for during this event and is subject to change based upon system requirements. Continue to monitor Natural's interactive website for any updates to the end date and/or scheduling percentages during this event.
