Effective Timely Cycle for gas day Sunday, December 28, 2025, and continuing until further notice, SNG restricted the following:
OPERATIONAL FLOW ORDERS (OFO)
Type 3 Level 1 OFO North System will be in effect for the start of the gas day, Monday, December 29, 2025 until further notice, Notice ID # 711519
Type 3 Level 1 OFO South System will be in effect for the start of the gas day, Monday, December 29, 2025 until further notice, Notice ID # 711518
Type 6 OFO Warning
Based on current milder temperatures resulting in lower demand on Southern's system, SNG encourages all shippers to manage their system requirements to maintain balance between actual receipts and deliveries. An Operational Flow Order for long imbalances could be required to help ensure system integrity as Southern's Tariff provides that a Type 6 OFO can be implemented on four hours' notice or less prior to the start of the gas day. - See Notice #711510
