These maintenance outages will impact the availability of transportation services moving south to north through Compressor Station 115.  The current schedule is to complete the work from May 6, 2025 through June 3, 2025.

During this period of planned maintenance, non-secondary reverse path (NSRP), secondary FT, and interruptible (IT) transactions moving south to north through the location may not be available.

Transco will be required to manage transportation services moving south to north through the TSB location listed below. The total quantity available will be contingent on system conditions during the maintenance period and is anticipated to be initially limited to the quantities indicated below. Transactions moving north to south through this location will not be impacted.

The receipt-based Throughput Section Boundary (TSB) at Mainline MP 1031 will be used to manage capacity availability, including any required changes to the expected total quantities available during this planned work indicated below. An updated Market and Production Area constraint notice will include the location and the available quantity of primary-firm transportation services during the indicated periods.
