The discharge of an on-board toilet or waste holding tank is in direct violations of the DOT Code of Federal Regulations (CFR) and is enforceable by the US Coast Guard or thier deemed agency. Any vessel equipped with a toilet must have a approved holding tank, marine sanitation device and a lockable y-valve for overboard discharge prevention. No vessel shall discharge sewage in inland lakes, waterways or estuaries without an approved MSD. A vessel must be at least 3 miles offshore to discharge untreated or non-MSD treated sewage overboard. There is no need for additional law or mandates, enforce the ones that exist. Very hefty fines exist for this, oily waste and garbage discharge. There is actually a $5000.00 fine ready for any boater over 40 ft that can't present a written "Garbage Plan" to the USCG when boarded. There are adequate pumpout facilities at WB and no excuse for overboard discharge, just flat out laziness and or negligence!
