Thank you for your report! This is not EAB. It's a native member of the Metallic Wood-boring beetle family, the Golden Buprestid, Buprestis aurulenta. These beetles are larger and less slender than EAB. They are not tree killers. Their grubs live in dead conifers.

There are a number of iridescent green look-alike beetles in Oregon that are not pests. I am attaching a link to the ODA EAB webpage with some photos of other Oregon insects that could be mistaken for EAB

EAB is an adult in the summer (May-Sept). EAB isn't known to be as far south as you are (so far!). Keep an eye out for the D-shaped emergence holes and S-shaped larval galleries under the bark of ash trees. Thanks for being on the lookout!
