# U.S. Oil & Refining Co. Tacoma Refinery

U.S. Oil & Refining Co. Tacoma Refinery, Tacoma, WA. 40,700 bpd crude capacity (EIA-820). Crude supply, outlets, events.

- Location: Tacoma, WA
- Status: active
- Crude capacity: 40,700 bpd (EIA-820)
- Operator: U.S. Oil & Refining Co. (dba U.S. Oil)
- Parent: Par Pacific Holdings, Inc.

## Crude supply
- marine: Blair Waterway marine terminal — The refinery sits on 136 acres including 11.5 acres of waterfront with 1,350 feet on the Blair Waterway, providing direct access for ocean-going barges and tankers.
- rail: Direct rail access / unit-train-capable rail terminal — Par Pacific's acquisition press release describes a 'unit train-capable rail loading terminal' as part of the U.S. Oil assets.
- marine: Blendstock receipt (ethanol, renewable diesel, renewable jet fuel) via new marine-terminal-to-refinery transfer lines — A 2018 Tacoma shoreline permit authorized three new 12-inch product-transfer lines from the Blair Waterway marine terminal to the refinery to move ethanol, renewable jet fuel, and renewable diesel for blending -- this is blendstock/feedstock, not crude oil, but is a real physical inbound connection worth noting for the graph.

## Product outlets
- pipeline: McChord Pipeline (McChord AFB jet fuel pipeline) — A dedicated 14.25-14.5-mile intrastate pipeline (6-inch steel, built 1966) runs from the U.S. Oil refinery to the McChord Air Force Base fuel storage facility, supplying it with jet fuel. Confirmed by WA Utilities and Transportation Commission pipeline inspection reports.
- marine: Blair Waterway marine terminal — Refined products (gasoline, diesel, marine and jet fuels, residual fuels, asphalt) move out via the same Blair Waterway waterfront used for crude receipt.

## Recent events
- 2026-02-20 — Olympic Pipeline mainline shut for roughly two days of maintenance-related activity, restarted evening of Feb 19, 2026; BP reported no product release.
- 2025-11-25 — 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.
