2. It shall be unlawful for any operator or person in control of a vessel being operated upon any waters of the state designated as vessel waste no-discharge zones to discharge sewage from marine toilets into such waters. Any marine sanitation device on board any vessel being operated in such waters must be secured to prevent any marine sanitation device discharges to such waters. In accordance with federal requirements, any marine sanitation device aboard any vessel being operated upon any waters within such vessel waste no-discharge zone shall be secured by closing the seacock and padlocking, using a non-releasable wire-tie, removing the seacock handle or locking the door to the "head" while such vessel is being operated upon waters within vessel waste no-discharge zones. If a marine sanitation device on any such vessel provides a means of discharging sewage directly to such waters, the discharge valve must be secured in a readily visible manner and closed position while the vessel is being operated upon such waters. Use of a padlock, heavy non-resealable tape, wire-tie, or the removal of the valve handle are adequate methods of securing the device. The method chosen shall be one that presents a physical barrier to the use of the valve. It is unlawful for any person operating or in control of a vessel with a marine sanitation device on board to operate or control such vessel in a vessel waste no-discharge zone when the marine sanitation device is not secured in the manner described herein.
