Subject: Unplanned Maintenance Station 115 MU3 Planned Outage and Maintenance Summary
Transco will be performing unplanned maintenance at Station 115 due to equipment failure on Main Unit 3 that requires immediate action. The current schedule for repairs is effective immediately July 29, 2025 through TBD. Transco will provide an updated completion date as soon as it becomes available.
During this period of unplanned 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 unplanned 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.

*% Cuts (Primary) is an estimate of the impact to primary firm shippers based on historical utilization and anticipated volumes during the time of constraint. These amounts are subject to change based on actual nominated firm volumes and changes in the amount of available capacity.
Based on current and historical utilization, impacts to Primary Transportation are unlikely, however, impacts to Non-Primary Transportation are anticipated.
