22 Proceedings Summer 2014 www.uscg.mil/proceedings Modern cruise ships are more than just foating hotels, these vessels are small cities incorporating every aspect of public works. As such, waste accumulates from food, recyclable materials, oil, chemicals, batteries, and water. Each vessel must deal with this continual cycle of creating, collecting, and processing wastes. Food waste and recyclable materials must be stored in lockers and processed in garbage rooms; hazardous garbage like chemicals for photo process- ing, dry cleaning, and batteries must be stored in protected lockers; oily wastes from machinery spaces must be stored in tanks and fltered; and used water must be stored and appropriately fltered prior to overboard discharge. The Waste Stream A material's life cycle on a ship is called a "waste stream," which refers to waste that is created, processed, and then eventually discharged from the vessel. Examiners refer to this as "cradle to grave," and categorize this waste into fve different types: • oil, • non-hazardous, • hazardous, • gray water (the water associated with sink and shower drains), • black water (sewage). Each Coast Guard foreign passenger vessel examination includes a waste stream audit, where the examiner ran- domly audits the vessel's waste management operations to ensure they meet federal and international regulations. All waste stream systems must follow fundamental pro- cesses that include a combination of administrative account- ability, machinery and equipment verifcation, operational practices, and crew training. Examiners work with an engi- neering offcer or an environmental offcer — whoever is responsible for the examined system.
