Crude slate

Not independently confirmed this session. Regional Salt Lake refineries as a group are understood to run a mix of Uinta Basin waxy/paraffinic crude and Wyoming/Rocky Mountain sweet crude; Big West Oil's specific slate could not be sourced within budget.

crude in truck Uinta Basin crude trucking
Not independently confirmed for Big West Oil specifically this session (search tools were unavailable/blocked for most of this task), but it is well established in industry reporting that Salt Lake-area refineries receive a substantial share of the region's waxy Uinta Basin crude by heated tanker truck because the crude's high paraffin content requires heating and no large common-carrier crude pipeline currently connects the Uinta Basin to Salt Lake City refineries (this gap is the stated rationale for the proposed Uinta Basin Railway rail project). Treat as a plausible inference, not a confirmed fact for this specific refinery.

Refinery-direct truck rack; self-evident for an operating refinery of this scale and consistent with Big West Oil's role supplying the regional Flying J/Pilot Flying J travel-center network by truck.

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.
