West Coast except California (PADD 5) diesel price

Pull California out of PADD 5 and what is left, by EIA's own accounting, is Oregon, Washington, Arizona, Nevada, Alaska and Hawaii, the district this page tracks. EIA publishes this rollup so the rest of the West Coast can be read on its own, apart from California's separate fuel specification and state taxes, which otherwise dominate the full PADD 5 figure. This subset is still a pipeline-isolated market, covered mostly by Pacific Northwest refining and by waterborne imports, so it still typically prices above the national average, though the gap is noticeably smaller than the full West Coast number once California's effect is removed.

Refinery activity around Puget Sound and the cost of import cargoes into West Coast ports are the main things that move it. For California on its own, see the California page.

The supply geography inside this rollup is not one market either. The Pacific Northwest runs on the Puget Sound refineries and the pipeline system that carries their product south toward Portland, which makes Washington and Oregon a reasonably connected pair. Arizona and Nevada, by contrast, have no refineries and are fed by pipeline from California and from the Gulf Coast, so their pump prices track California's more closely than the Pacific Northwest's does even though California has been removed from this figure. What are PADDs explains the district accounting behind that.

Alaska and Hawaii are inside this number too, and neither behaves like the mainland. Both are supplied locally or by marine cargo, both carry freight costs no continental market sees, and both are small enough that they move the rollup very little. Reading this page as a Pacific Northwest indicator is closer to right than reading it as a six-state average, because that is where most of the volume is.

What that leaves is a district still structurally short of supply and still cut off from the interstate pipeline network, but without the specification and tax layer that sets California apart. The gap to the national average is real and persistent, and it is mostly a freight and isolation story rather than a policy one, which is the distinction this split exists to make visible.
