Because of the large number of vessels, EPA believed that it made administrative sense to use general permits, rather than individual permits. In 1990, Congress enacted the Non-indigenous Aquatic Nuisance Prevention and Control Act (16 U.S.C. 4701 et seq) to focus federal efforts on non-indigenous, invasive, aquatic nuisance species, specifically when such species occur in ballast water discharges. That law, as amended by the National Invasive Species Act of 1996, delegated authority to the Coast Guard to establish a phased-in regulatory program for ballast water. Activity to regulate or prohibit cruise ship discharges also has occurred in several other states. In order for IMO standards to be binding, they must first be ratified by a total number of member countries whose combined gross tonnage represents at least 50% of the world's gross tonnage, a process that can be lengthy. Parties/countries that have ratified an Annex may propose amendments; MARPOL specifies procedures and timelines for parties to adopt amendments and for amendments to take effect.
Cruise ship efforts to reduce pollution
While this may sound like it would be harmful towards the environment, the water must meet stringent regulatory standards before dumping can begin. Essentially, the water must be completely clean and pose no serious risk to the health of local marine life and ecosystems. This type of wastewater is usually filtered and treated onboard the ship because modern cruise ships have sophisticated water treatment facilities.

The rule is one of several EPA regulations establishing emissions standards for nonroad engines and vehicles, under Section 213(a) of the Clean Air Act. Smaller marine diesel engines are regulated under rules issued in 1996 and 1999. Modern day cruise ships can carry several thousands of people who use the showers, toilets, pools and spa areas every day and all this results in astounding amounts of sewage material.
Do Cruise Ship Toilets Drain Into The Ocean?
As noted previously, the 110th Congress enacted legislation to implement MARPOL Annex VI, concerning standards to control air pollution from vessels. Complementing the IMO revisions, in December 2009, EPA promulgated changes to the 2003 CAA rules for Category 3 marine engines that essentially adopt the amended IMO requirements.47 The EPA rule also establishes emissions standards for hydrocarbons and carbon monoxide. Like the new Annex VI requirements, the EPA rule applies to newly built engines (not existing) and only to U.S.-flagged or registered vessels. On the latter point, EPA said that engines on foreign vessels are subject to the nitrogen oxide limits in MARPOL Annex VI, which the United States can enforce through the Act to Prevent Pollution from Ships (APPS). There is fear in some coastal communities that as cruise ship traffic increases, so too will the threat to their waters.

All six Annexes have been ratified by the requisite number of nations; the most recent is Annex VI, which took effect in May 2005. The United States has ratified Annexes I, II, III, V, and VI, but has taken no action regarding Annex IV. The country where a ship is registered (flag state) is responsible for certifying the ship's compliance with MARPOL's pollution prevention standards. IMO also has established a large number of other conventions, addressing issues such as ballast water management, and the International Safety Management Code, with guidelines for passenger safety and pollution prevention. 16 tons of food waste are produced on average each week on a medium-sized cruise ship.
Is The Filtered Water On A Cruise Ship Recycled From Toilet Water?
Some wastes are covered by international standards, some are subject to U.S. law, and for some there are gaps in law, regulation, or possibly both. The report then describes federal and state legislative activity concerning cruise ships in Alaskan waters and activities in a few other states. Cruise ship companies have taken a number of steps to prevent illegal waste discharges and have adopted waste management plans and practices to improve their environmental operations. Environmental critics acknowledge these initiatives, even as they have petitioned the federal government to strengthen existing regulation of cruise ship wastes. Environmental groups endorsed legislation in the 109th and 110th Congresses (the Clean Cruise Ship Act) that would require stricter standards to control wastewater and other discharges from cruise ships.

Certain waste waters are released without treatment but only those that haven’t come into contact with biohazardous materials or chemicals. By a three to one margin cruise passengers want the industry to stop dumping human waste into the ocean, according to a new poll released today by Oceana, an international advocacy organization dedicated to restoring and protecting the world’s oceans. Yes, you read that correctly – Most cruise ships are equipped with a modern wastewater management system onboard, complete with engineers who monitor the treatment of waste that goes down the drains and toilets on the ship. Older ships have in the past dumped human waste into the ocean once the ship was 12 nautical miles away from port, however this is a rare occurrence today, especially among the major cruise line operators. Thanks to advanced technologies, high standards, and government regulations, cruise ships deal with sewage sustainably and professionally, protecting passengers, crew members, and the waters that cruise ships travel through.
On Uniworld, both collection and offloading are more frequent, given the closer proximity of port. Cruises are not a beacon of environmentally responsible transport, but cruise lines are working hard to improve their standards, in terms of waste and other ways they can cause pollution. This is usually a result of the guests ordering more dishes than they can eat, or loading their plates heavily at the buffet and not finishing everything. The first step for sewage on a cruise ship is to enter an aeration chamber. This chamber is filled with bacteria which work to break down some of the organic compounds in sewage that contaminate it, removing them from the wastewater. Generally, treated water is permitted to be dumped in many areas that aren’t too close to land, while untreated waste can still be dumped according to regulations, but it must be further from shore.
Cruise Ship Pollution: Background, Laws and Regulations, and Key Issues
It refers to highly polluted waste water, containing fecal solids from the toilet system, bacteria, as well as traces of prescribed medications and hormones. To go from gruesome to golden, black water is treated in several steps – mechanically, biologically, as well as chemically. The first step is the mechanical treatment of the water, whereby coarse impurities (particles with a diameter of less than one millimeter) are mechanically filtered out.
When we talk about human waste, we’re generally referring to black water. However, each ship must follow specific regulatory requirements when disposing of waste, according to the EPA. All major cruise line operators belong to an organization called “CLIA” – Cruise Lines International Association.
In 1988, President Reagan signed a proclamation (Proc. No. 5928, December 27, 1988, 54 Federal Register 777) providing that the territorial sea of the United States extends to 12 nautical miles from the U.S. baseline. However, that proclamation had no effect on the geographic reach of the Clean Water Act. About 10% of scrubber washwater discharged from ships off British Columbia occurred within critical habitats of orcas, according to an analysis by the International Council on Clean Transportation. Of particular alarm, says Kuehnemund, is the threat to wildlife in Scott Islands marine national park, a cluster of five islands off the north-western tip of Vancouver Island. This protected area is subject to the highest amount of pollution from cruise ship dumping, according to WWF’s report. Sadly, cruise lines of the past did not treat water before releasing it into the sea or ocean.
This report presents information on issues related to cruise ship pollution. It begins by describing the several types of waste streams and contaminants that cruise ships may generate and release. It identifies the complex body of international and domestic laws that address pollution from cruise ships, as there is no single law in this area.
Additional waste water is generated by the laundry, kitchen and other servicing facilities on board. Throughout the years, many cruise lines have been accused of dumping their wastewater directly into the ocean, but maritime regulations have changed in the recent past and all modern cruise ships are obliged to have their own wastewater treatment plant on board. To understand how it functions, let’s look at the four main types of wastewater on ships and how each type is processed. Under the VGP, cruise ships are subject to more detailed requirements for certain discharges, such as graywater and pool and spa water, and additional monitoring and reporting. It includes BMPs as well as numeric effluent limits for fecal coliform and residual chlorine in cruise ship discharges of graywater that are based on U.S. Coast Guard rules for discharge of treated sewage or graywater in Alaska (see discussion below, page 19).
Shipboard incinerators also burn large volumes of garbage, plastics, and other waste, producing ash that must be disposed of. Cruise ships confront the challenge of wastewater, a complex mix of organic and inorganic contaminants that, if released untreated, can harm the marine environment and public health. To address this, vessels are equipped with sophisticated Advanced Wastewater Treatment Systems (AWTS) capable of purifying wastewater before it’s discharged into the sea. My DH who was an active duty and is now a reserve Naval Officer says 25 years ago a lot of ships, including the US Navy dumped all kinds of stuff overboard. They bring their garbage to port and treat their sewage (if they have the means). There is an officer on board US Navy ships whose job is to arrange to have the garbage disposed of properly.
