NOTICE OF FORCE MAJEURE ANR Pipeline Company – Southeast Area – Patterson Compressor Station

SEV 4/5Force Majeure1.403 Bcf/d10 days

Summary

ANR Pipeline has declared a Force Majeure at Patterson Compressor Station (Southeast Area) due to an unexpected Unit 2 equipment failure, effective 8/18/2026 intraday through 8/27/2026. Eight interconnect locations face curtailed capacity ranging from full elimination (Patterson to Col Gulf, leaving 0 MMcf/d) to partial reductions across Shadyside/TGP, Weeks ISLA, Shadyside/Sonat, and Avalon delivery points. Aggregate stated capacity reductions across the listed locations total approximately 1,403 MMcf/d (1.403 Bcf/d) removed from scheduling, with the Shadyside/TGP (Del) cut of 443 MMcf/d and Weeks ISLA/LIG PL cut of 260 MMcf/d being the largest individual impacts.

Trading note

ANR Patterson FM removes approximately 1.403 Bcf/d of combined Southeast-area scheduling capacity through 8/27; expect bullish pressure on ANR Louisiana basis and Transco Zone 4 as Gulf Coast northbound flows are curtailed, with the Patterson-to-Col Gulf location going to zero delivery capacity and Shadyside/TGP delivery cut from 473 to 30 MMcf/d -- tightest signal at Southeast and Midwest interconnects receiving from ANR's Louisiana mainline.

Reroute potential

Moderate: Texas Eastern (TETCO), Trunkline (TGC), and Columbia Gulf Transmission (CGT) serve overlapping Gulf Coast northbound corridors, but the scale of reductions across multiple interconnects -- including a full cut to the Col Gulf interconnect -- limits the ability of any single alternative to absorb displaced volumes. Partial reroute is possible but full offset is unlikely over the 10-day FM window.

Any reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 6.36 of ANR’s FERC Gas Tariff (“Tariff”). However, ANR will only issue RCCs if ANR is unable to schedule or deliver primary firm nominated capacity as a result of the outage. In the event RCCs are issued as set forth in the Tariff, shippers will receive RCCs based on its 7-day Non-Force Majeure Average Usage Quantity, as defined in Section 6.36.2 of ANR’s Tariff, less any scheduled quantities on the contract. By means of this notice, ANR is establishing which specific Gas Days will be included when determining a shipper’s 7-day Non-Force Majeure Average Usage Quantity pursuant to Section 6.36.2(b) of the Tariff.
