[Cheyenne Connector] [MAINTENANCE] CHEYENNE CONNECTOR MAINTENANCE SCHEDULE FOR NOVEMBER 2026
Capacity Constraintcapped at 0.805 Bcf/d, cut unknown
Ruby Pipeline is issuing Update #3 to the Roberson Compressor Station operational issue first posted October 14, 2025 (Notice ID 13046). Effective Evening Cycle Gas Day October 19 and ID3 cycle October 19, 2026, and until further notice, Ruby will schedule Segment 20 to a cap of 0.805 Bcf/d. At this cap level, secondary firm and ITS/AOR service classes are at risk of not being scheduled.
Ruby Seg 20 capped at 0.805 Bcf/d UFN with secondary firm and ITS/AOR at risk; bullish SoCal Border and Pacific Northwest as Opal-to-Malin westbound capacity remains constrained with no reroute alternative for California-bound volumes.
Reroute: Limited: Northwest Pipeline provides some alternative for Pacific Northwest deliveries, but no comparable westbound Rockies-to-California alternative exists to replace Ruby volumes; EPNG and Kern River serve California from the south/east but do not substitute for Opal-originating supply on the same path.

[Tallgrass Interstate Gas Transmission (TIGT)] [MAINTENANCE] TIGT MAINTENANCE SCHEDULE FOR OCTOBER 2026 - UPDATE #1
TIGT has declared an operational alert on Segment 520 from Otis to Stockton due to an ongoing pipeline integrity issue requiring section replacement, effective Gas Day August 25, 2026 (ID1 Cycle), and the outage is expected to last longer than originally anticipated with no restoration date given. Primary firm, secondary firm, and interruptible/as-available service quantities are all at risk of not being scheduled on this segment. TIGT is working with affected customers on alternative connections but cannot guarantee full scheduling of nominations.
TIGT Segment 520 (Otis to Stockton) is offline indefinitely with firm service at risk; Cheyenne Hub regional basis has averaged -0.442 vs Henry Hub over the five trading days ended 2026-09-02 (most recently -0.410 on 2026-09-02) and further bearish pressure on Rockies/Midcontinent regional basis is likely until a restoration timeline is established -- no capacity volume is quantified in the notice.
Reroute: Limited: TIGT serves the Rockies-to-Midcontinent corridor, and while PEPL and Southern Star serve overlapping Midcontinent markets, the integrity-driven segment outage with no restoration timeline makes full volume displacement uncertain; affected customers are being worked individually for alternative connections per the notice.
Trailblazer Pipeline declared a force majeure at its Heartwell Location (Location 60487) on Gas Day September 2, 2026, caused by electrical storms. Effective the ID2 cycle on September 2 and the Timely cycle on September 3, operating capacity at Heartwell is scheduled to 0 MDth/d until further notice. Primary and secondary firm quantities as well as ITS/AOR are explicitly stated to be at risk of not being scheduled.
Trailblazer FM at Heartwell zeros 0.008 Bcf/d of local capacity at Location 60487 with firm service at risk and no restoration timeline; while the isolated location impact is small, the force majeure declaration with 'until further notice' duration and primary firm curtailment language warrants monitoring -- Cheyenne Hub regional basis was already at -0.465 vs HH as of 2026-09-01 and any escalation to mainline throughput would pressure that spread further.
Reroute: None: Trailblazer shares Bertrand Compressor Station with REX, making REX a correlated rather than independent reroute option; the specific Heartwell location serves local delivery points with no identified bypass.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #16
SEV 4/5
Operational Alert0.818 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 is restricted to 0.818 Bcf/d effective Gas Day August 1, 2026, until further notice due to a third-party operational issue at Bertrand Compressor Station (Update #16). At this restricted level, primary firm, secondary firm, and interruptible service are all at risk of not being scheduled. No restoration timeline has been provided.
Trailblazer Segment 20 restricted to 0.818 Bcf/d with primary and secondary firm at risk; because Trailblazer leases capacity at Bertrand CS on REX, REX Zone 1 is simultaneously constrained -- reroute is effectively zero, expect bearish pressure at CIG/Cheyenne Hub as Rockies gas backs up with no viable takeaway alternative.
Reroute: None: Trailblazer and REX share Bertrand Compressor Station -- this is the same third-party facility constraining both pipes simultaneously, meaning REX cannot serve as an independent reroute for Trailblazer volumes. This is a correlated constraint with zero bypass for affected Rockies eastbound capacity.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #15
SEV 4/5
Capacity Constraint0.815 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 is restricted to 0.815 Bcf/d effective Gas Day July 1, 2026, until further notice due to a third-party operational issue at Bertrand Compressor Station. This is Update #15, indicating an ongoing multi-week constraint with no restoration timeline. Primary firm, secondary firm, and interruptible service are all at risk of curtailment.
Trailblazer Segment 20 capped at 0.815 Bcf/d with firm service at curtailment risk; because Trailblazer leases capacity at Bertrand CS on REX, this constraint simultaneously limits REX Zone 1 eastbound egress -- expect bearish pressure on Rockies and Midcontinent basis with no independent reroute available.
Reroute: None: Trailblazer leases capacity at Bertrand Compressor Station on REX, meaning REX Zone 1 is simultaneously constrained by the same third-party facility -- these are not independent reroute options. CIG provides limited alternative Rockies egress but cannot fully absorb stranded volumes.

[Trailblazer Pipeline (TPC)] [FORCE MAJEURE] HEREFORD COMPRESSOR STATION FORCE MAJEURE
SEV 5/5
Force Majeure0.021 Bcf/dUntil Further Notice
Trailblazer Pipeline (TPC) declared a force majeure at its Hereford Compressor Station effective Gas Day June 19, 2026, ID2 cycle, and continuing until further notice. Operating capacity at Location 60361 is restricted to 20.9 MDth/d (approximately 0.021 Bcf/d), an extreme reduction from normal throughput. Primary firm, secondary firm, and interruptible service are all at risk of curtailment.
Trailblazer FM at Hereford CS cuts operating capacity to just 0.021 Bcf/d with no restoration timeline; primary and secondary firm service at risk -- expect bearish pressure on Rockies basis at CIG/Cheyenne Hub as eastbound Rockies takeaway collapses, with reroute to REX potentially compromised given shared infrastructure at Bertrand CS.
Reroute: None: Trailblazer leases capacity at Bertrand Compressor Station on REX -- when Trailblazer is constrained at a shared facility, REX Zone 1 is simultaneously affected and does not represent an independent reroute; CIG provides limited partial alternative for some Rockies volumes but cannot absorb a full Trailblazer outage.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #14
SEV 5/5
Compressor Issue0.808 Bcf/dUntil 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.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #13
SEV 4/5
Compressor Issue0.819 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 capacity is restricted to 0.819 Bcf/d effective Gas Day May 1, 2026, until further notice, due to an ongoing third-party operational issue at Bertrand Compressor Station (Update #13). This is the 13th update on a continuing event with no restoration timeline. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled, indicating the constraint is severe enough to threaten firm service.
Trailblazer Segment 20 restricted to 0.819 Bcf/d with firm service at risk; given REX and Trailblazer share Bertrand CS, this constraint simultaneously limits both pipes -- expect bearish pressure at Rockies/CIG basis with no viable reroute for affected volumes.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both pipelines are simultaneously constrained by the same third-party facility, eliminating any independent reroute option for Rockies eastbound volumes.

[Trailblazer Pipeline (TPC)] [FORCE MAJEURE] REDTAIL COMPRESSOR STATION FORCE MAJEURE
SEV 5/5
Force Majeure0.030 Bcf/dUntil Further Notice
Trailblazer Pipeline declared force majeure at Redtail Compressor Station effective Gas Day April 15, 2026, reducing operating capacity to only 30 MDth/d (0.030 Bcf/d) until further notice. Primary firm, secondary firm, and interruptible service are all at risk of curtailment. No restoration timeline has been provided; end date is listed as 12/31/9000, indicating an indefinite outage.
Trailblazer FM at Redtail CS cuts operating capacity to 0.030 Bcf/d with all service classes at risk; this effectively eliminates Trailblazer as a functional eastbound Rockies takeaway path, expect bearish pressure on CIG/Cheyenne Hub Rockies basis as gas backs up in the Rockies, with offsetting bullish pressure at Midcontinent and Northern Natural Gas downstream delivery points.
Reroute: None: Trailblazer leases capacity at Bertrand CS on REX, and REX Zone 1 is the primary correlated alternative -- when Trailblazer is constrained at a compressor station upstream of Bertrand, REX may face correlated pressure; Colorado Interstate Gas (CIG) provides a partial alternative for some Rockies volumes moving south, but cannot fully absorb Trailblazer's eastbound capacity.
