No passing the buck here!!
If the inbound goes around, technically it's essentially an Approach problem!
I beg to differ but if there's a go-around the tower controller has blown it and has to ensure that there is either:
- visual separation between the departing aircraft and the one going around or
- a continuing radar separation standard or
--in a non radar environment a procedural standard can be established ie the aircraft departing has left a level on climb such that there is an available level for the aircraft going around to be assigned
