5-10.2.2 Transferring void bilge water to sludge facility
WARNING
USCG regulations prohibit discharge of oil, fuel or chemically contaminated water
upon the navigable waters and contiguous zones of the United States. If such a
discharge causes a film or sheen upon or discoloration on the surface of the water
or causes a sludge or emulsion beneath the surface of the water, the USCG must
be notified by telephone or radio as soon as contamination takes place. As soon
as steps have been taken to stop spillage, the USCG must be contacted again.
Anyone violating these regulations is subject to a fine.
