What is the regulation regarding the disposal of plastic material from a vessel?

The disposal of plastic materials from a vessel is heavily regulated to protect the marine environment from pollution. According to international and domestic regulations, including the MARPOL protocol, certain types of waste, particularly plastics, are prohibited from being dumped into the sea altogether, regardless of distance from shore. This regulation reflects the understanding that plastic waste poses significant threats to marine life and ecosystems, with no safe distance at which disposal is allowed.

While there may be specific regulations regarding other materials and different distance limits for those, for plastic waste, strict restrictions apply, necessitating that vessels handle disposal on land rather than at sea. Therefore, the statement indicating that none of the specified distances are correct aligns with these stringent environmental protections.
