Emerald ash borer larva? #428326

I was splitting and stacking ash wood and came across this critter. Pics on the internet don't quite match this for emerald ash borer larva but I thought I'd just confirm. I don't think the emerald ash borer has been found in ND yet either so I'm even more doubtful it is but thought I'd double check.
Pembina County North Dakota
Expert Response
This appears to resemble a Carpenterworm. How large are the exit holes? Carpenterworms typically leave large round exit holes - around 1/2 inch - and a large amount of sawdust may be present at the base of the ash. A helpful publication can be found at the following web address: ipm.ucanr.edu.
