Pollution Regulations
Marpol Treaty:
The USCG now enforces the International
Convention for the Prevention of Pollution from
ships, referred to commonly as the MARPOL
TREATY (marine pollution). This international
treaty prohibits the overboard dumping of all oil,
garbage, ship-generated plastic and chemicals.
There is a placard on board your boat (typical
example shown below) that explains the garbage
and plastic dumping laws in detail.
Immediately notify the USCG if your vessel
discharges oil or hazardous substances in the
water. Call toll free 1-800-424-8802. Report the
following information: location, source, size, color,
substances and time observed.
No vessel may intentionally drain oil or oily waste
from any source into the bilge of any vessel. A
bucket or bailer is suitable as a portable means of
discharging oily waste.
The placard noted above is normally located in the
engine compartment or may be attached to the
engine hatch.
