Crude slate
Not specifically documented in the sources reviewed. The refinery is generically described as low-complexity, receiving crude by marine barge/tanker and rail via its Blair Waterway/Commencement Bay terminal; no source named a specific crude type or source region.
Crude in & products out
| Direction | Mode | Route | Point / origin | Products | Source |
|---|---|---|---|---|---|
| crude in | rail | U.S. Oil & Refining Co. crude-by-rail unloading station The plant has 107 crude railcar offloading stations, 38 of which can also offload ethanol. The regional air permit worksheet gives a crude throughput of 34,775 barrels a day (12,658,100 barrels a year) for the station. The delivering railroad is not named. |

| crude in | marine | U.S. Oil & Refining Co. Docks 1 and 2, Blair Waterway The air permit worksheet says the facility receives crude oil by rail and ship. NOAA Coast Pilot 10 lists Docks 1 and 2 on the Blair Waterway, owned and operated by U.S. Oil & Refining Co., with 1,095 feet of berthing space and 40 feet of depth alongside, for receipt and shipment of petroleum products. |

| products out | pipeline | McChord Pipeline McChord Pipeline is a buried intrastate line 14.25 miles long, built in 1966 with 6-inch steel pipe. It carries jet fuel from the refinery to the McChord Air Base storage facility at Joint Base Lewis-McChord and ends at the custody transfer manifold there. The Washington Utilities and Transportation Commission inspected it in 2022 under McChord Pipeline Company. |

| products out | marine | U.S. Oil & Refining Co. Docks 1 and 2, Blair Waterway The air permit worksheet says the facility sends out finished products by ship. Ethanol arrives by railcar at the crude-by-rail unloading station and is loaded onto vessels at Dock 1, up to 3,616,600 barrels a year under the permit. A 2018 Tacoma shoreline permit authorized three 12-inch transfer lines between the marine terminal and the refinery for ethanol, renewable jet fuel and renewable diesel. |

| Bay Area and Puget Sound refineries → Los Angeles / Long Beach marine terminals Northern California "regularly supplies parts of Southern California and Oregon by marine vessel"; Southern California took about 16,000 b/d of distillate by marine from other West Coast regions (2013). CEC (2024): after the Martinez/Rodeo conversions the Bay Area will no longer have surplus gasoline for Southern California; Washington cargoes are a regular source. |

Events

outage
Olympic Pipeline mainline shut for roughly two days of maintenance-related activity, restarted evening of Feb 19, 2026; BP reported no product release. source

2025-11-25
outage
A leak on BP's shared Olympic Pipeline near Everett, WA halted refined-product deliveries (including jet fuel to Sea-Tac Airport) region-wide for nearly two weeks; the Olympic system's Segment 2 destination point is Tacoma. Because Tacoma is a delivery point rather than an origin on Olympic Pipeline, this event affects any Olympic-sourced product reaching the Tacoma area generally, but is not confirmed to touch the U.S. Oil refinery's own crude/product flows. 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.
