Macerators 'Illegal' in Long Island Sound ?

So I did a two night cruise this last weekend, and I am chatting with the guy at the pump out dock in Manhasset bay. Making conversation I tell him that my macerator has no valve before the holding tank, and that if it ever clogged / jammed I would not be able to clear it out without dumping crap in my bilge. I guess I could head to a pump out theoretically, but I am based by Gravesend Bay, so I could be out a ways, certainly beyond the three mile limit for discharge of recognizable sewage.

Anyhow, he says a macerator is illegal on new boats anyhow, so I would never be using it (my boat is an 89 Catalina). What is he talking about? I am interpreting this as within Long Island Sound (a no discharge zone). He had a bushy grey beard, so I assumed he was smarter than me on all things nautical. I have glasses *and* a goatee, so I'm not sure if I would outrank him on land.

Definitely not. But I don't know the answer to your other question.

Maritime Sanitation - The Law

All I can see is that a macerator does not count as a type 1,2,or 3 sanitation device. But your holding tank does.

Re: Macerators 'Illegal' in Long Island Sound ?

LIS is not a "no discharge," zone (although just about every harbor on it is, and now any part of it that CT claims as their waters)...but that does NOT mean that it's legal to dump a tank in LIS. It's not...which, while it does not make it illegal to have a macerator installed on your boat in LIS, does make it illegal to use it in LIS.

You must be outside the "3 mile limit" to dump a tank or flush a toilet
directly overboard. That does not mean just three mile from the nearest shore in a bay, sound, lake or means that you must be in open ocean at least 3 miles from the nearest point on the whole US coastline--iow, in international waters--to dump a tank legally anywhere in the US.

However, except in the 90+% of harbors on LIS that have been designated "no discharge," the discharge of treated waste from a CG certified Type I or II MSD (treatment device) IS legal on LIS...and the whole Chesapeake Bay except for Herring Bay...and at least 90% of the rest of the waters between LIS and the FL Keys.

So unless your bushy bearded guy at the pumpout dock was referring to CT waters, he doesn't know what he's talking about. But then, there's a LOT of that going around!

Btw...pumpout and thoroughly rinse out your tank...and then put either a y-valve or a shutoff valve in your tank discharge line so you can cut off the flow from the tank to the macerator if you have to...which you will...'cuz all macerators eventually need new impellers, or even outright replacement.
