What is true of a No Discharge Zone (NDZ)?

A No Discharge Zone (NDZ) is an area designated by local or state authorities where the discharge of sewage from boats is strictly prohibited. This regulation aims to protect water quality in sensitive aquatic environments, such as marinas, swimming areas, and places with abundant marine life. In these zones, all vessels must have adequate onboard sewage treatment facilities or utilize pump-out stations, emphasizing the importance of managing waste responsibly to avoid pollution and preserve ecosystem health.

The other options do not apply to the definition of an NDZ. Charging batteries and exhaust mufflers relate to equipment use and noise control but are not regulated under NDZ laws. Additionally, discharging water is not subject to restrictions in an NDZ concept, as this typically refers to sewage and not general water discharges. Hence, the focus of an NDZ is entirely on preventing sewage discharge, making the first statement the accurate one.
