the base of the toilet opens a mechanical seal and

The Environmental Protection Agency (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

PERATION
Waste from the head is directed into the 68 gallon
( 257.4 liter) holding tank located in the starboard
forward bilge (See figure 7.11.1). Holding tank
fluid level indicators are located on the DC
distribution panel in the salon and in each head.
The head indicators read OK TO FLUSH and DO
NOT FLUSH (See figure 7.11.2). When the DO
NOT FLUSH light is on, the holding tank must be
emptied before the head can be reused. However
it would be a good practice to empty the holding
tank when the 1/2 light (on the DC Distribution
panel) is on to avoid overflowing the holding tank
and ruining the vent filter.
There is the possibility of being fined for having
an operable overboard discharge in U.S. waters.
Removing handle of seacock while in closed
position, or other means must be utilized to avoid
fine.
It is illegal for any vessel to dump plastic trash
anywhere in the ocean or navigable waters of the
United States.
NOTICE
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
interconnecting 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).
