No it is a different type of woodborer (likely western cedar borer) that is not of concern as it's native and takes out dead and dying trees - often drought-stressed arborvitae in sun-exposed lots. Emerald ash borer is smaller and thinner than this beetle, see more info here: https://www.oregon.gov/ODF/Documents/ForestBenefits/Woodboringbeetles.pdf
