Events

2026-06-29
outage
Large smoke plume and roughly 20-ft flare after a thunderstorm, attributed to wastewater burn-off. A refinery source said it was 'possibly due to power lines being knocked down during the storm'. The refinery's own fire department responded. source

2026-06
outage
Bismarck Tribune: a Sunday-evening 'brief operational upset' caused significant flaring. Marathon said flares worked properly, regulators were notified and there was no indication of off-site impact. The exact date was not visible (paywalled). The search engine dated the article about 98 days before 2026-10-05, i.e. around 2026-06-28/29, so it may be the same storm-related event as above. source

Rates are pipeline line-haul transcribed from published FERC tariffs; every figure cites its tariff and item. Cost to serve (netback) adds origin spot price and destination fees. "Confirmed" links match a tariff delivery point to the facility; "same city" means the point is in the facility's city — plausible, not proof; "per research" means the facility's research profile names the pipeline as an outlet.
