Well, I live and boat exclusively in the Maryland portion of the Chesapeake Bay. The laws and regulations are very specific on this, as follows:
"Most boaters know that it’s illegal to discharge raw sewage from a boat within U.S. territorial waters, including the entire Chesapeake Bay, coastal bays and their tributaries. In Maryland, a law allows Natural Resources Police to enforce sewage laws with fines up to $2,000."

Your situation is apparently much different then mine.
