The next time you decide to jump into Boston Harbor -- don't. It seems Boston boaters like to empty their on-board toilets directly into the harbor.

And right now --- it's perfectly legal. But that may change later today, according to the Associated Press. The Environmental Protection Agency is expected to outlaw dirty dumping today --- signing off on legislation that wuold make Boston the largest urban area in the nation with such a ban.

City leaders say the ban would improve conditions at area beaches. Really?
