of at least 5 by 8 inches, made of durable
material fixed in a conspicuous
place in each machinery space, or at
the

stating the following:
DISCHARGE OF
OIL PROHIBITED
The Federal
Water Pollution Control Act
prohibits the discharge of
oil or oily waste
into or upon the navigable waters of the
United States, or the waters of the contiguous
zone, or which may affect natural resources
belonging to, appertaining to, or
under the exclusive management authority
of the United States, if such discharge causes
a film or discoloration of the surface of the
water or causes a sludge or emulsion beneath
the surface of the water. Violators are subject
to substantial civil penalties and/or
criminal sanctions including fines and imprisonment.
33 CFR § 151.59 Placards
(b) The master or person in charge of
each ship under paragraph (a)(1) or
(a)(2) of this section shall ensure that
one or more placards meeting the requirements
of this section are displayed
in prominent locations and in
sufficient numbers so that they can be
read by the crew and passengers. These
locations must be readily accessible to
the intended reader and may include
embarkation points,
food service facilities,

or location of the placards is insufficient
to adequately inform crew and
passengers, the
Captain of the Port
may require additional placards and
may specify their locations.
(c) Each placard must be at least
nine inches wide by four inches high,
made of a durable material, and lettered
with letters at least 1⁄8 inch high.

this section, the placard must notify
the reader of the following:

mixed with plastic into any waters
is prohibited.

prohibited in the navigable waters of
the United States and, in all other waters,
within three nautical miles of the
nearest land.
(3) The discharge of dunnage, lining,
and packing materials that float is prohibited
