This maintenance activity may impact the availability of transportation services moving south to north through Compressor Station 70. Due to an unexpected issue with first tool run, an additional tool run has been added to the schedule. The current schedule for this maintenance is December 10, 2024 to December 12, 2024.Decemeber 15, 2024 to December 17,2024. 

 

The specific dates that will be impacted are subject to change, but the current schedule is outlined below.

The receipt-based Throughput Section Boundary (TSB) at mainline milepost 662 (Station 70) will be used to manage the available capacity during this planned work.
