    (16) Whether the device is Type I, II, or III.
    (17) A statement as follows:
    Note: The EPA standards state that in freshwater lakes, freshwater 
reservoirs or other freshwater impoundments whose inlets or outlets are 
such as to prevent the ingress or egress by vessel traffic subject to 
this regulation, or in rivers not capable of navigation by interstate 
vessel traffic subject to this regulation, marine sanitation devices 
certified by the U.S. Coast Guard installed on all vessels shall be 
designed and operated to prevent the overboard discharge of sewage, 
treated or untreated, or of any waste derived from sewage. The EPA 
standards further state that this shall not be construed to prohibit the 
carriage of Coast Guard-certified flow-through treatment devices which 
have been secured so as to prevent such discharges. They also state that 
waters where a Coast Guard-certified marine sanitation device permitting 
discharge is allowed include coastal waters and estuaries, the Great 
Lakes and interconnected waterways, freshwater lakes and impoundments 
accessible through locks, and other flowing waters that are navigable 
interstate by vessels subject to this regulation (40 CFR 140.3).
