I need to clog 3 times a chimney on Xupi Nüü, can't find them

[TDBtje]

During the game on 3 locations you get the instruction "Clog the chimney using explosives". Can't find the location / how to do that....

If this is after the part where you take photos of the 3 factories and the pipelines, then it's Xupi Maano - the big factory bit at the bottom of the southern island. Stock up on lamps/bombs/explosives and then fly up to the top of the chimneys and chuck 3 into each one.

EDIT: The main objective is "Clog 3 chimneys" but the game doesn't say you have to do the 3 other factories first. So if you complete the ones in the north, east and west (shutting off generators, freeing an animal and disabling drills respectively) THEN you should be able to clog up the chimneys in the one to the south.
