Spill management team means the personnel identified to staff the organizational structure identified in a response plan to manage response plan implementation.

Substantial threat of such a discharge means any incident involving a vessel that may create a significant risk of discharge of cargo oil. Such incidents include, but are not limited to, groundings, strandings, collisions, hull damage, fire, explosion, loss of propulsion, flooding, on-deck spills, or other similar occurrences.

Appendix B of this part, especially Tables 5 and 6, provide specific guidance on calculating the response resources required by each tier. Sections 155.1050(g), 155.1135, 155.1230(d), and 155.2230(d) set forth the required times within which the response resources must arrive on scene. Tiers are applied in three categories:

(1) Higher volume port areas;

(2) The Great Lakes; and

(3) All other operating environments, including rivers and canals, inland, nearshore, and offshore areas.

Vegetable oil means a non-petroleum oil or fat not specifically identified elsewhere in this part that is derived from plant seeds, nuts, kernels or fruits.

Vessel of opportunity means a vessel engaged in spill response activities that is normally and substantially involved in activities other than spill response and not a vessel carrying oil as a primary cargo.
