This has been in the news off and on for a few years now. Basically, until the Fed says they have to do one of the two (shut it down, or build the cooling towers), FL Power is going to drag its feet as slow as it can. That is one truly corrupt and morally bankrupt company. Thankfully for me, they are on the other coast, and about 250 miles from me.....
It's not really "leaking", though it's a good headline. They simply aren't managing the wastewater as cleanly as they should be. I don't think it was intentional, FL just has some geographic challenges when it comes to this. But, what IS intentional, is how they are waiting until a mandate to actually do anything about it....
They did the same kind of thing before Crystal River was shut down.
