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.
