[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #14

SEV 5/5
Compressor Issue 0.808 Bcf/d Until Further Notice

Trailblazer Pipeline Segment 20 remains restricted to 0.808 Bcf/d effective Gas Day June 2, 2026, until further notice due to an ongoing third-party operational issue at Bertrand Compressor Station -- now in its 14th update. Primary firm, secondary firm, and ITS/AOR quantities are all explicitly at risk of not being scheduled. No restoration timeline has been provided.

Bertrand CS constraint caps Trailblazer at 0.808 Bcf/d with firm service at risk; because REX leases capacity at the same Bertrand CS facility, these two Rockies eastbound pipes are simultaneously constrained -- expect continued bearish pressure on Rockies basin (CIG/Cheyenne Hub) as eastbound takeaway remains impaired with no reroute.
Reroute: None: Trailblazer and REX share the Bertrand Compressor Station -- the same third-party facility constraining Trailblazer simultaneously affects REX Zone 1, eliminating the primary reroute alternative for Rockies eastbound volumes.

[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #14

SEV 5/5
Compressor Issue 1.115 Bcf/d Until Further Notice

Rockies Express Bertrand Compressor Station operational issue (Update #14) restricts Segment 250 West-to-East capacity to 1.115 Bcf/d effective Gas Day June 2, 2026, until further notice. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled. No restoration timeline has been provided.

REX Segment 250 constrained to 1.115 Bcf/d W-to-E with primary and secondary firm at risk; Trailblazer shares Bertrand CS and is simultaneously affected -- expect bullish pressure at Midcontinent and Chicago Citygate as Rockies takeaway is curtailed with zero independent reroute.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both are simultaneously constrained by the same facility, leaving no independent reroute for Rockies eastbound volumes. CIG provides limited alternative egress but cannot absorb full displaced volumes.

[OPERATIONAL FLOW ORDER] SOC System Wide Pack - Update #1

SEV 3/5
Operational Alert Until Further Notice 1 Days

EPNG has issued a System-Wide Pack Operational Flow Order effective 06/01/2026 at 9:33 AM through 06/02/2026 at 9:00 AM. The OFO requires shippers to maintain or increase system line pack across the entire EPNG system, restricting nomination flexibility for one day. No specific capacity volume is stated in the notice.

EPNG system-wide pack OFO constrains shipper scheduling flexibility across the full Permian-to-California corridor for approximately one day; expect mild bearish pressure at Waha as outbound nominations are restricted, with modest bullish signal at SoCal Border and Arizona delivery points if westbound throughput is curtailed.
Reroute: Moderate: Transwestern Pipeline (TW) serves overlapping SoCal border and Arizona markets and can absorb some displaced Permian westbound volumes, though pack OFOs typically reflect system-wide stress that may limit the degree of reroute benefit.
