It's not ideal if the brine is dumped in one location. If it is dumped deep enough it gets a chance to be diluted before it hurts the environment.

In the end, all fresh water goes back to the ocean so it's not like we would be creating an imbalance, there's just a risk of causing local damage.

Yeah the local imbalance is what worries me. I have a mental image of a big long 'soaker hose' style brine dumping pipe rather than a single outlet, that way the brine is further diluted. Wonder how much that helps.
