This is a company-operated gathering system, distinct in name from 'Belle Fourche' or 'Bridger' (which are separate, True Companies-owned crude pipeline/gathering systems operating in the same basin). |

Events
No events on record.
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.
