Shipboard Marine Pollution Emergency Plan (SMPEP) is required by vessels carrying what?

• A. Oil
• B. Noxious Liquid Substances
• C. Garbage
• D. Sewage

Answer: (B)

Shipboard Marine Pollution Emergency Plan is required on ships that carry noxious liquid substances in bulk. This plan provides a structured set of procedures for preventing pollution and for responding to a spill, including who to notify, how to activate the plan, and what equipment and actions are needed, coordinated with authorities and salvage teams. Noxious liquid substances are chemicals listed under MARPOL Annex II, and handling them safely in an emergency requires specific steps, roles, and communications laid out in the SMPEP. Other pollution areas have their own plans—oil has its own oil pollution emergency plan (SOPEP), while garbage and sewage have separate management and prevention requirements—so SMPEP is specifically tied to those hazardous liquids carried in bulk.
