I guess we're a bit behind you in our regulations.
I sail in Nova Scotia waters. My homeport is Halifax.

There are no coastal (or inland) waters in the whole US--east coast,
west coast, or Gulf--in which it's legal to discharge raw untreated
toilet waste directly overboard or dump a tank. So unless you're only
using the the head when you're out to sea at least 3 miles from the
nearest point on the whole US coastline, or it's going through CG
certified Type I MSD (device that treats waste before discharging it
overboard) first, you're discharging it overboard illegally.
