boat sewage is "peanuts" compared to other sources of pollution, that holding tanks "stink," that there's no place to pump out, and that the law isn't being enforced anyway, is no longer valid. These facts are clear: Growth in boating is placing an additional environmental strain on crowded recreational waters. Government and citizens' groups are working aggressively to contain and prevent all forms of water pollution. Government grant money is funding a tremendous increase in the number of pump-out facilities. Advancing technology has given a wide range of "user friendly" sanitation system options. Against this backdrop, it is not surprising that congress is considering proposals that would increase fines for flushing raw sewage and provide states with incentives for enforcing current laws. Clearly, it's time for all boaters to "do the right thing." Boats 65 feet in length or less may install a type I, II, or III device. Vessels over 65 feet must install a type II or III MSD. An approved system (Type I or II) will have a label verifying that it meets the Coast Guard regulations for design and construction and the Environmental Protection Agency (EPA) regulations and standards as required by the Clean Water Act. Holding tanks (Type III) do not require a certification label if they simply store sewage at ambient temperatures and pressures. Which SystemIf the boat is operated in waters designated for "No Discharge", you only have one choice...you must retain all sewage, treated or not, for disposal ashore. Choosing the system that works best will depend on several factors. The answer to a few questions about how the boat is used should help you narrow the choices and determine optimal holding tank capacity: How many people are usually on board for a trip? Is the boat usually used for day trips or for longer periods and overnight cruises? Usually day trips do not generate much sol...
