Gulf South Pipeline Company, LLC (""""Gulf South"""") is informing shippers that it has limited
operational flexibility within the East Whistler Receipt and East Whistler Delivery Scheduling
Groups. Due to unforeseen delays with the pipeline maintenance, the following points and
scheduling groups will be scheduled down through at least the start of Gas Day 11/1/2026.

The following points will be shut-in for the duration of the maintenance:
- Loc 7362 (Mobile-Saraland)
- Loc 20777 (Jacinto Port (Bayou Sara Junction))
- 1 Spire Farmtap

East Whistler Receipt Scheduling Group:
- Loc 2926 - Flomaton-(Florida Gas Crossover) - 28,000 Dth/d
- Loc 17114 - Santa Rosa (From FGT) FFP - 24,000 Dth/d
Receipt capacity will be limited to 52,000 Dth/d for the duration of the maintenance.

East Whistler Delivery Scheduling Group:
Delivery capacity may be reduced by up to 133,000 Dth/d for the duration of the maintenance. This
maintenance event has the potential to impact all services, including Primary Firm Service. No
impact is anticipated to net zero nominations within the East Whistler Delivery Scheduling Group
that remain below the 52,000 dth/d receipt capacity through the East Whistler Receipt
Scheduling Group. Lower-than-normal operating pressures are expected.

Saraland Deliveries Scheduling Group:
No impact is anticipated to net zero nominations between the receipt point (Loc 23352 – (Bay Gas
Storage @ Axis)) and delivery points on Index 301-8-20. Lower-than-normal operating pressures are
expected.

Gulf South is informing shippers that it cannot absorb due shipper imbalances across the system:
1. Shippers are not to deliver to the pipe less than scheduled quantities at receipt points.
2. Shippers are not to take from the pipe more than scheduled quantities at delivery points.
3. As nearly as possible, Customer shall deliver and receive gas in uniform hourly quantities
during any day. Subject to Gulf South's operating conditions, during any given day and its sole
discretion, Gulf South may allow Customer to deliver or receive gas at an hourly rate that
exceeds 1/24 of Customer's scheduled quantities.

Gulf South will be monitoring location performance and may be required to take the following
action:

Delivery locations may be subject to scheduling reductions when the net scheduled delivery
quantities minus the “Projected Daily Quantities” exceeds the greater of 5% of net scheduled
delivery quantities or 1,000 Dth. Demand charge credits will not be issued during the maintenance
period unless Primary Firm
Service is scheduled down during the Timely Nomination Cycle. Any demand charge credits will be
calculated pursuant to Section 6.25 of the General Terms and Conditions of Gulf South`s NGA Gas
Tariff.
