Subject: Update Job #41165 Station 80 to Station 100 MLC Planned Outage and Maintenance Summary

Transco will be performing necessary pipeline inspection maintenance associated with Job #41165 on its 2024 Planned Outage and Maintenance Summary. This maintenance activity may impact the availability of transportation services moving south to north through Compressor Station 90. The current schedule for this maintenance is Nov 4, 2024 to Nov 20, 2024. 

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

Gauge Tool – 11/4 – 11/5 

Cleaner Tool – 11/6 – 11/7 

Combo Tool – 11/11 – 11/12 

CMFL Tool – 11/13 – 11/14 11/15

EMAT Tool – 11/18 – 11/19 11/20

During this period of planned maintenance, non-secondary reverse path (NSRP), secondary FT, and interruptible (IT) transactions moving south to north through the location will not be available. On days that maintenance is not occurring, the availability of transportation services moving south to north will not be impacted. 

Operating Conditions resulting from this work will also require Transco 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 but is anticipated to be limited to the quantity indicated below. Transactions moving north to south through this location will not be impacted. 

The receipt-based Throughput Section Boundary (TSB) at mainline milepost 812* (Station 90) will be used to manage capacity availability including any required changes to the expected total quantity available during this planned work. An updated Market and Production Area constraint notice will include the location and the available quantity of primary-firm transportation services during the indicated period.

*As defined on Transco's Informational Postings site under Operational Capacity, any constraint between the Mainline milepost 784.0 and 944.25 involving restriction of Primary volumes will result in the Operating Capacity being reflective of the amount available for both Transco and Sabal Trail.  However, the Total Scheduled Quantity represents Transco volumes only. The scheduled volumes of Sabal Trail shippers are reported under Sabal Trail’s Informational Postings Page. The Operationally Available Capacity takes into account both the Transco Scheduled Quantity and the scheduled volumes of Sabal Trail shippers posted by Sabal Trail. 

**% 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
