You need to look at the underlying act, not just the CFR. Look at
Section 312 of the Federal Water Pollution Control Act (33 U.S.C. 1322),
under marine sanitation devices. It states, in part:

(6) ‘‘sewage’’ means **human body wastes and** emphasis added the
wastes from toilets and other receptacles intended to receive or retain
body wastes except that, with respect to commercial vessels on
the Great Lakes, such term shall include graywater;

From the same section:

(9) ‘‘discharge’’ includes, but is not limited to, any spilling,
leaking, pumping, pouring, **emitting** emphasis added, emptying or
dumping;

It's clear from the underlying act that human wastes, contained in
non-biological containers or not, are "sewage", and cannot legally be
discharged untreated. I'll happily bow to Peggie's greater knowledge
regarding enforcement, but it seems clear that hanging your butt over
the rail in the marina isn't legal.

Interesting. Seems like that would still allow for a lot of "local
discretion" however.


Not a bit. The regulations say you must secure the device to prevent
discharge. They do not say you must secure your ass to prevent discharge.
You can look it up.
