Planning standards for spills of oils that, depending on their chemical properties, environmental factors (weathering), and method of discharge, may submerge or sink.
(1) Plan holders carrying, handling, storing, or transporting oils that may weather and sink when spilled to the environment must have a contract with a PRC that maintains the resources and/or capabilities necessary to respond to a spill of nonfloating oils. Examples of these types of oils include, but are not limited to, crude oil, diluted bitumen, group V oils, low American Petroleum Institute oil, decant, asphalt, and asphalt products.
(2) The plan holder or contracted primary response contractor must have the necessary personnel and equipment capable within the time frames outlined in the table below:
Time (hours) | Capability |
1 | Initiate an assessment and consultation regarding the potential for the spilled oil to submerge or sink. |
6-12 | Resources and personnel to detect and delineate the spilled oil such as side scan or multibeam sonar, laser fluorosensors, induced polarization, 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 personnel necessary to assess the impact of the spilled oil on the environment could have arrived. Types of resources that may be used for this purpose include sampling equipment. |
Additionally, dredges, submersible pumps, sorbents, agitators, or other equipment necessary to recover oil from the bottom and shoreline could have arrived. |
(3) The contingency plan must detail the process for identifying if the oil handled has the potential to submerge or sink 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.
