should anyone be surprised that oil arriving thru the new bigger pipeline is intended for shipping overseas, since there isn't the refining capacity to process it locally (including WA)

Some of it is, but the Washington state refineries mostly run on Alaskan crude, supplemented by crude oil coming from pipelines, and from rail:

The US market is broken into Petroleum Administration for Defense Districts (PADDs) and PADD 5 (the West Coast, Alaska and Hawaii) is not effectively interconnected to the rest of the US by pipelines. As such it mostly must be self-sufficient or must import oil.
The thing is, Alaska's oil fields are starting to run dry:

Because Alaska's production of crude oil is in continual decline, barring a major oil discovery in Alaska that's relatively easy to access, PADD 5 is experiencing a supply shortage of crude oil, which is causing pressure on pricing for refined products.
As such, in recent years, the Washington state refineries have been looking for alternative sources of crude, and they've been sourcing from both whatever they can get from Trans Mountain, and via oil by rail shipments (mostly Bakken crude with some Canadian oil sands supply as well), which currently make up over 25% of Washington state's imports.
Right now, the current pipeline is over 30% over subscribed by shippers looking to ship through the pipeline, and Trans Mountain has been running at capacity for years:

A expanded KM pipeline allows for two things to happen, which will impact refined fuel pricing in the long term;
1. Increased and a more steady supply of refined fuel from Alberta (which currently supplies about 55,000 barrels per day), which produces more refined product than they need;
2. Feeds Washington state refineries, which also supplies a significant portion of refined products to BC (30,000 barrels a day). Currently, Trans Mountain sends about 54% of it's supply down the Sumas spur line to the Washington state refineries, and this is expected to increase to meet demand in Washington state.
