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

DirectionModeRoutePoint / originProductsSource
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.
Not established crude source
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.
Not established crude source
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.

The IRS active fuel terminals list dated 8/30/2026 carries the refinery's own address as terminal T-91-WA-4421 under U.S. Oil & Refining Co. The air permit worksheet says the facility sends out finished products by truck.

By sea

From the refinery’s product wharf: 34 deepwater-dock terminals in 6 rack markets on the coastwise lanes the research documents (and on upriver by barge). Lanes are regional evidence — sources rarely say which refinery supplies which terminal — so treat these as where this plant’s product can go by vessel, graded by the lane’s evidence.

Puget Sound refineries → Portland
Over 90% of Oregon's fuel comes from Washington refineries: "about 75 percent by Olympic Pipeline to Oregon, remaining product by tanker ships" (other ODOE pages say pipeline and barge).

No document names the marine supply of the Vancouver WA terminals; inferred from their Columbia River docks and the Portland lane. They may instead be barged from Portland.

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.

Puget Sound refineries → Southeast Alaska (Inside Passage)
Crowley: Southeast Alaska fuel is "sourced from refineries in the Pacific Northwest" (Tacoma, Anacortes, and Vancouver BC) and moved by tug and barge to depots, one via Ketchikan, every 20 days to weekly. Refinery attribution is illustrative, not exclusive; Juneau imported about 20 million gallons of gasoline in 2013.

Petroleum barges "originate at the Port of Portland and are offloaded to fuel racks at the Ports of Umatilla and Pasco": 902,240 short tons in 2019 (737,983 in 2020), about 38% of upbound tonnage and declining. No evidence was found for The Dalles or Lewiston/Clarkston.

  1. 2026-02-20 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

  2. 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.
