Under what regulation are pollution prevention regulations for facilities and vessels found?

The pollution prevention regulations for facilities and vessels are found under 33 CFR 154-156, which encompass the regulations that aim to prevent oil spills and other discharges of pollutants into navigable waters. This regulation specifically addresses both the operational and contingency requirements for marine transportation and storage facilities. It includes stipulations regarding the design and maintenance of facilities, as well as response actions in the event of a spill.

While the other options pertain to different regulatory areas, they do not directly address pollution prevention for facilities and vessels. For instance, 40 CFR 117.3 relates to the discharge of hazardous substances in relation to spill reporting requirements, rather than comprehensive prevention measures. Similarly, 49 CFR 171-178 deals primarily with the transport of hazardous materials and may not include pollution prevention specific to marine facilities or vessels. Lastly, 32 CFR 626 focuses on military regulations and does not pertain to civil pollution prevention practices. Thus, 33 CFR 154-156 is the correct choice as it specifically outlines the pollution prevention framework governing the operations of these maritime entities.
