The International Convention for the Control and Management of Ships' Ballast Water and Sediments (Ballast Water Management Convention or BWM Convention) is a 2004 international maritime treaty which requires signatory flag states to ensure that ships flagged by them comply with standards and procedures for the management and control of ships' ballast water and sediments. [2]
The new regulations have the same requirements for avoiding uptake and discharge in sensitive areas and for recording and reporting ballast water in vessels. The management of ballast water were expanded to include training and safety procedures as well as maintenance and removal practices of foulding species and sediment.
The VGP sets numeric ballast water discharge limits for large commercial vessels. The limits are expressed as the maximum acceptable concentration of living organisms per cubic meter of ballast water. [11] The Coast Guard worked with EPA in developing the scientific basis and the regulatory requirements in the VGP. [5]
Norwegian Dawn and Carnival Dream moored alongside in New Orleans (2015). Cruise ships carrying several thousand passengers and crew have been compared to “floating cities,” and the volume of wastes that they produce is comparably large, consisting of sewage; wastewater from sinks, showers, and galleys (); hazardous wastes; solid waste; oily bilge water; ballast water; and air pollution.
The Coast Guard issued ballast water regulations in 2012. [14] Under the authority of the Clean Water Act, the Environmental Protection Agency (EPA) published its latest Vessel General Permit in 2013. The permit sets numeric ballast water discharge limits for commercial vessels 79 feet (24 m) in length or greater.
In 2021, The New York Times wrote that the IMO "has repeatedly delayed and watered down climate regulations". [54] The IMO has also taken action to mitigate the global effects of ballast water and sediment discharge, through the 2004 Ballast Water Management Convention, which entered into force in September 2017.

The New York Department for Environmental Conservation has announced new length limits for recreational striped bass fishing during the 2024 season. NY introduces new length limits for 2024 ...
This water, called ballast water, which contains aquatic organisms typical of the port of arrival, is stored in ballast tanks and is ultimately discharged at the port of departure when the ship is ready to be re-loaded. During this process, aquatic organisms capable of surviving in ballast water are released into new environments and can ...
