Thank you for your report! This is not EAB. It's a native member of the Metallic Wood-boring beetle family, Chrysophana placida. These beetles are 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

Thanks for being on the lookout!
