for the mode of deployment of the equipment at the location of the uncontrolled well; (c) the schedule and plan for the mobilization, deployment and operation of the source control and containment equipment, including measures to minimize deployment time that take required regulatory approvals into account; (d) details regarding the accessibility of the source control and containment equipment and the documents and information referred to in paragraphs (a) to (c); (e) an explanation of the adequacy of each of the source control and containment measures; and (f) a description of any support systems and equipment that are available, including vessels and remotely operated vehicles and any consumables that may be used, such as, in the case of a relief well, a spare wellhead, spare casing and spare bulk additives. Spill-treating agent (4) If a spill-treating agent is being considered for use as a spill response measure, the contingency plan must include the following additional documents and information: (a) the name of the chosen spill-treating agent and details of an assessment of its efficacy in treating the potential sources of pollutants, including the results of any tests conducted for the assessment and a description of those tests; (b) the results of an analysis that demonstrates that a net environmental benefit is likely to be achieved through the use of the spill-treating agent under certain circumstances; (c) a description of the circumstances under which the spill-treating agent will be used and the estimated period within which its use will be effective; (d) a description of the methods and protocols, including the amount and application rate, for safe, effective and efficient use of the spill-treating agent; (e) a list of the personnel roles, equipment and materials that an operator will have available for the purpose of using the spill-treating agent, including any to be provided through contractual arrangements, and a description of the requirements that must be met for those contracts to be activated; and (f) a monitoring plan for the use of the spill-treating agent. Assessment of efficacy (5) The assessment of efficacy under paragraph (4)(a) must be carried out using oil obtained directly from the operations site where the spill-treating agent is being considered for use or, if oil is not available from that operations site, it must be carried out using an oil that most closely resembles the oil that is expected to be obtained from the operations site and must be repeated when oil becomes available from that operations site. International standard or alternative (6) The assessment, analysis, methods and protocols referred to in paragraphs (4)(a), (b) and (d) must be based, taking the local environment into account, on an international standard or an alternative recognized by the Board and the contingency plan must identify each of those standards or alternatives. Methods and protocols (7) The methods and protocols referred to in paragraph (4)(d) and the monitoring plan referred to in paragraph (4)(f) must conform to industry standards and best practices for spill-treating agent use, taking the local environment into account. Definition of source control and containment equipment (8) In this section, source control and containment equipment means the capping stack, containment dome, any subsea and surface equipment, devices or vessels and any relief well drilling installations that are used to contain and control a spill source and to minimize the duration of a spill and its environmental effects until well control is regained.
