Question 66

The Correct Answer is A **Explanation for A (U.S. Coast Guard):** The U.S. Coast Guard (USCG) is the primary federal agency responsible for maritime safety, security, and environmental stewardship in U.S. waters. Federal regulations, specifically the Clean Water Act and its implementing regulations (33 CFR 159), require that all Marine Sanitation Devices (MSDs) used on vessels be certified by the Commandant of the U.S. Coast Guard to ensure they meet the established performance standards for sewage discharge. **Why the other options are incorrect:** * **B) American Bureau of Shipping (ABS):** ABS is a classification society primarily focused on setting standards for the design, construction, and operational maintenance of vessels and offshore structures for safety and structural integrity. While they certify various components, they do not hold the federal authority to certify MSDs for compliance with environmental discharge regulations; that authority rests with the USCG. * **C) Society of Naval Architects and Marine Engineers (SNAME):** SNAME is a professional society that provides technical information and standards for the maritime industry. It is an advisory and educational body, not a regulatory or certifying authority for mandated equipment like MSDs. * **D) Environmental Protection Agency (EPA):** The EPA establishes the *performance standards* (criteria and testing protocols) that MSDs must meet to prevent water pollution under the Clean Water Act. However, the EPA delegates the authority to officially *certify* and approve specific devices as compliant with those standards to the U.S. Coast Guard.
