Incinerator ash discharge at sea is ever permitted?

• A. Always
• B. Sometimes
• C. Never
• D. Only with permit

Answer: (C)

The main idea is that discharging incinerator ash at sea is not allowed under typical ship pollution rules. Incinerator ash is considered a form of garbage produced on board, and releasing garbage into the ocean is restricted to protect marine environments. Even though ships may incinerate waste, the resulting ash must be retained on board or taken ashore for proper disposal, rather than dumped into the sea. This is because ash can contain residues and contaminants that harm marine life and ecosystems, and international rules aim for minimizing any sea discharge of waste. Therefore, there isn’t a permitted scenario that allows releasing incinerator ash at sea, even with a permit; the proper, compliant practice is to keep it on board until shore disposal.
