USCG Ballast Water Management Regulation in the USA

For many years, the United States has been affected by invasive species. That is why the U.S. Coast Guard now prohibits ships to discharge untreated ballast water in U.S. waters.

Linked to the National Invasive Species Act of 1996, the US Coast Guard (USCG) established in 2004 the rules for controlling the discharge of Living Organisms from ships’ Ballast Water in US waters, through publication of 33 CFR Part 151 and 46 CFR Part 162.

The Rules have been effective since June 21, 2012, and can be downloaded from the Federal Register website:
