(a) No person may operate an oceangoing ship of 10,000 gross tons and above, or any oceangoing ship of 400 gross tons and above, that carries ballast water in its fuel oil tanks, unless it has—
(1) Approved 15 ppm oily-water separating equipment for the processing of oily mixtures from bilges or fuel oil tank ballast;
(2) A bilge alarm; and
(3) A means for automatically stopping any discharge of oily mixture when the oil content in the effluent exceeds 15 ppm.
