It's exactly that kind of image that keeps people from looking at the math. If I were one mile offshore, how many gallons of seawater would be between us? Do you really think that a holding tank, which would not be solid after being pumped afterall, would not fully dilute?

Let's have some facts instead. A cubic foot of water contains approximately 7.5 gallons. As there are 5,280 feet in one mile, if depth averaged 20 feet, that would be 105,600 cubic feet of water or 792,000 gallons of water for every linear foot of shore out to one mile. Say your beach is one mile long? That's 4.2 billion gallons of water inside that little box. Now contemplate the entire Bay, Ocean, etc.

How many recreational boats are out there and how much will their tanks actually hold?

To be clear, seawater already contains the excrement of every living creature in it and that volume far exceeds anything you and I could possibly add. There is a point where those concentrations are harmful to the environment and that should be the standard, not the silly total prohibition from anyone at anytime.

Did you know that the 3 mile limit is strictly the limit of the Federal Law that allows a State to regulate the shoreline? It has no environmental relevance.
