Under the federal regulations of 33 CFR Subchapter O, if a vessel equipped with a Type III Marine Sanitation Device enters a body of water where the discharge of untreated sewage is prohibited, which of the following methods of securing the device to prevent the discharge of sewage is UNACCEPTABLE?
AI Explanation
The correct answer is C) Closing and tagging each valve leading to an overboard discharge.
According to 33 CFR 159.7(b), when a vessel is operated in an area where the discharge of untreated sewage is prohibited, the Marine Sanitation Device must be secured to prevent the discharge of sewage. Closing and tagging each valve leading to an overboard discharge is an acceptable method, as the tag provides a clear visual indication that the valves are secured.
The other options, while potentially effective, are not explicitly listed as acceptable methods in the regulations. Padlocking the valves (option D) could work, but tagging provides clearer visual verification. Options A and B, using a non-releasable wire-tie or removing the valve handles, are not mentioned in the regulations as approved methods for securing the device.
