The discharge of ballast water and sediments by ships is governed globally under the Ballast Water Management Convention, since its entry into force in September 2017. It is also controlled through national regulations, which may be separate from the Convention, such as in the United States .

All international sea going ships under the Convention must implement a ‘Ballast water management plan’ that enables the ship to manage their ballast water and sediment discharge to a certain standard. [7] The plan is designed to meet the requirements for compliance with the Convention and the G4 Guidelines produced by the IMO.
A cargo ship discharging ballast water into the sea. Ballast water discharges by ships can have a negative impact on the marine environment. [1] Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever ...
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 ...
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]
