An environmental group is suing in federal court seeking better regulation of cruise ships and the sewage they dump into the ocean.
Friends of the Earth, represented by Earthjustice, want more effective regulation of the industry, said to dump more than a billion gallons of sewage — much of it poorly treated — into the ocean last year.
The group also is seeking better regulation of the sewage discharged from cargo ships and oil tankers.
Friends of the Earth said in a news release on May 1 that the sewage from the ships pollutes beaches, contaminates coral reefs and destroys marine ecology.
Sewage contamination also puts swimmers at elevated risk of illness and can make seafood caught by coastal fishermen unsafe to eat.
Also, discharges from ships disrupt coastal economies.
In 2012, ship sewage contributed to elevated levels of fecal coliform that led to more than 31,000 days of beach advisories and closings.
“Sewage-contaminated waters not only harm sea life, but also harm people who use these waters,” said Marcie Keever, oceans and vessels program director at Friends of the Earth. “These ship sewage discharges contribute to the risk of serious, potentially life-threatening health effects such as gastrointestinal illnesses, hepatitis, ear nose and throat illnesses, vomiting, and respiratory diseases. The EPA reported in 2000 that its ship sewage treatment standards were out of date and needed an update. After 38 years, it is time for EPA to act.”
Sewage discharge close to shore has been banned in the New England area but not in the Northwest, the Gulf of Mexico or the Southeast.
Several years ago, the Friends of the Earth petitioned the EPA and asked that it update its 1976 performance standards and pollution limits for onboard marine sanitation devices — the systems used to treat sewage on ships.
The EPA has not proposed any changes.
A report in 2013 from the group indicated that Disney, Norwegian, Royal Caribbean, Celebrity, Cunard and Seabourn Cruise Line have installed advanced sewage treatment systems in a majority of their ships, while Carnival, Silversea, Costa and Crystal Cruises received failing grades in the review.
