The results of this sampling are available www.epa.gov/owow/oceans/cruise_ships/results.html. Grey water is water from sinks, showers, bushes, washing and cleaning activities on board a ship. It can contain a large number of pollutants, including fecal coliform bacteria, detergents, oil and fat, metals, organic matter, petroleum hydrocarbons, nutrients, food waste, and medical and dental waste. Samples taken by the EPO and the State of Alaska have shown that untreated greywater from cruise ships may contain pollutants with different levels and may contain a fecal coliform content one to three times higher than that of untreated domestic wastewater. Cruise ships produce an average of 67 gallons/day/person of gray water (or about 200,000 gallons per day for a cruise ship with 3,000 people); In comparison, gray water production in residential areas is estimated at 51 gallons/person/day.11 Gray water has the potential to cause negative effects on the environment due to concentrations of nutrients and other oxygen-intensive materials. Greywater is generally the largest source of liquid waste produced by cruise ships (90%-95% of the total). In Alaska, where tourism and commercial fishing make an important contribution to the economy, pollution from cruise ships has received considerable attention. After the state experienced a triple increase in cruise passenger numbers in the 199049 years, Alaska Natives and other groups began to worry about the impact of cruise ship pollution on marine resources. In a prominent example of environmental violations, Royal Caribbean Cruise Lines reached a federal criminal agreement in July 1999 providing for total fines of $6.5 million for violations in Alaska, including the scientific release of oil and hazardous substances (including dry cleaning and photo processing products). The company has admitted to a fleet-wide practice of dumping oil-contaminated bile water. Alaska`s sanctions were part of a larger $18 million federal deal, which involved environmental violations in several places, including Florida, New York and California.
Yardley wants Marlborough to follow Fiordland`s lead on how it handles cruise ship emissions with its long-standing Certificate of Agreement. Solid waste produced on a ship includes glass, paper, cardboard, aluminum and steel cans, and plastics. It can be either harmless or dangerous in nature. Solid litter entering the ocean can become marine litter and then pose a threat to marine organisms, people, coastal communities and industries that use marine waters. Cruise ships typically manage solid waste through a combination of source reduction, waste reduction and recycling. However, up to 75% of solid waste is incinerated on board and ash is usually dumped at sea, although some is landed for disposal or recycling. Marine mammals, fish, sea turtles and birds can be injured or killed by adding plastics and other solid waste that can be released or disposed of by cruise ships. On average, each cruise passenger produces at least two pounds of safe solid waste per day and disposes of two bottles and two boxes.12 For large cruise ships with several thousand passengers, the amount of waste can be huge in a day….
