(1) Plan holders carrying, handling, storing, or transporting oils, that may weather and sink when spilled to the environment, must have or contract with a PRC that maintains the resources and/or capabilities necessary to respond to a spill of nonfloating oil spills.

(2) The plan holder or contracted primary response contractors must have equipment capable of arriving within the time frames outlined in the table below:

Time (hours)	Capability
6	Initiate an assessment and consultation regarding the potential for the spilled oil to submerge or sink.
6-12	Resources to detect and delineate the spilled oil such as side scan or multibeam sonar, sampling equipment, divers, remotely operated vehicles or other methods to locate the oil on the bottom or suspended in the water column could have arrived.
	Additionally, containment boom, sorbent boom, silt curtains, or other methods for containing the oil that may remain floating on the surface or to reduce spreading on the bottom could have arrived.
12-24	Resources and equipment necessary to assess the impact of the spilled oil on the environment oil could have arrived.
	Dredges, submersible pumps, or other equipment necessary to recover oil from the bottom and shoreline could have arrived.

(3) Additionally, the contingency plan must detail the process for identifying if the oil handled has the potential to sink or submerge and include a description of the process for detecting, delineating, and recovering nonfloating oils in the areas that may be impacted. In lieu of including nonfloating oils response details in the contingency plan, plan holders may cite the nonfloating oils response tools found in the NWACP.
