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.

The Coast Guard issued ballast water regulations, pursuant to NISA, in 2012. [12] The Coast Guard requires ballast water treatment systems [13] [14] and began approving these systems in 2016. [15] The requirements generally apply to all non-recreational vessels equipped with ballast tanks. [16]
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.
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]
Hyde GUARDIAN ® Ballast Water Treatment System Earns Alternate Management System Approval from United States Coast Guard PITTSBURGH--(BUSINESS WIRE)-- Calgon Carbon Corporation (NYS: CCC ...
It specifies tanker design features that are intended to minimize oil discharge into the ocean during ship operations and in case of accidents. It provides regulations with regard to the treatment of engine room bilge water for all large commercial vessels and ballast and tank cleaning waste . It also introduces the concept of "special sea ...
In order to minimise regrowth and hence avoid exceeding discharge limits, different criteria such as duration of the journey, ballast water tanks capacity and water flow rate at intake and discharge, among others, should be considered when choosing an appropriate type-approved ballast water treatment system (BWTS).
The methods used to avoid having these invasive species surviving in ballast tanks however greatly increased the rate of corrosion. Therefore ongoing research attempts to find water treatment systems that kill invasive species, while not having a destructive effect on the ballast tank coatings. [6]
