Notice Text:
Subject: Unplanned Maintenance - 190A0 to 195A10 Mainline A Immediate Integrity Dig
Due to findings from an integrity assessment performed on Mainline A in April associated with Job #1071384. Transco will need to isolate and reduce pressure on a portion of Mainline A between 190A0 and 195A10 near Mile Post 1628.78. Transco is starting work to address this finding and will provide a return to service date as soon as it is available.
During this period of unplanned maintenance, non-secondary reverse path (NSRP), secondary FT, and interruptible (IT) transactions moving through the location may not be available.
Operating Conditions resulting from this work will require Transco to manage all transportation services north to south through the location listed below. The total quantity available will be contingent on system conditions during the maintenance period, but is anticipated to be limited to the quantity indicated below. Transactions moving south to north through this location will not be impacted.
The receipt-based Throughput Section Boundary (TSB) at mainline MP 1628.78 (Station 190) will be used to manage capacity availability during this unplanned work. An updated Market and Production Area constraint notice will include the location and the available quantity of all transportation services during the indicated period.
