I think the limits on the river are placed by the tribes and fisheries. I can tell you these are hard limits that are hard to get around. 
Also there are some large water rights on Central Whidbey that are going to have to be replaced that I am sure you are not aware of. 
Also Im not sure the current pipeline could carry that kind of addition concurrent load. I haven't crunched the numbers.
Also it wasn't like the Navy did it out of the good of their hearts they created the mess it is on them to clean it up.
If you disagree with this then I guess you disagree with our constitution as well and I suggest you take a course in constitutional law at local college.
