Ballast Water Treatment – USCG Amending Regulations

USCG to amend regulations on BWT systems, allowable concentration living organisms

The Coast Guard is amending its regulations on ballast water management by establishing a standard for the allowable concentration of living organisms in ships' ballast water discharged in waters of the United States.

The Coast Guard is also amending its regulations for engineering equipment by establishing an approval process for ballast water management systems. These new regulations will aid in controlling the introduction and spread of nonindigenous species from ships' ballast water in waters of the United States.
