What is true of a No Discharge Zone or NDZ?

A No Discharge Zone (NDZ) is a designated area where the discharge of sewage from vessels is prohibited. This aims to protect water quality in sensitive areas, such as near drinking water sources, swimming beaches, or habitats for wildlife. The enforcement of this regulation helps to minimize pollution and improve the overall health of aquatic ecosystems.

The focus on sewage, rather than other waste materials, is crucial because untreated sewage can introduce pathogens and harmful substances into the water, posing risks to human health and the environment. Therefore, while other types of discharge, such as fuel, may be regulated in different contexts or areas, the specific law governing NDZs pertains explicitly to sewage discharge.
