Actually no. Notice that round thing in the middle of the airport? It's called a VOR. Probably an overlay approach..
It can't be an overlay approach; no mention of the VOR anywhere (apart from it's location) and the last waypoint is the runway threshold - can't use the VOR for that. Have a look at the 30 VOR approach from this page; 10 degrees different on the inbound track; hardly likely to be an overlay:
