They really stretched regulations and started building - with the possibility for approval being denied thus the whole thing having to be teared down. Basically creating facts, I think that has created immense pressure on local politics/regulators. Also considering the region has lots of structural problems. It's quite incomprehensible to me why it wouldn't have been possible to build it a few kilometers further where there's no water protection area. Not to mention they had a number of water contamination incidents since then
