The US Department of the Interior has issued final regulations governing future exploratory drilling activities on the US Arctic Outer Continental Shelf (OCS). The Arctic-specific regulations focus solely on OCS exploratory drilling operations from floating vessels within the US Beaufort and Chukchi Seas.
These rules require oil companies to ensure proper internal controls and planning for oil spill prevention, containment and responses—all issues identified by previous Interior reports regarding Shell’s 2012 exploration activities in the Arctic. The regulations codify and further develop current Arctic-specific operational standards to ensure that operators take the necessary steps to plan through all phases of OCS exploration in the Arctic, including mobilization, maritime transport and emergency response, and the conduct of safe drilling operations while in theater.
Specifically, the final rule requires operators to develop an Integrated Operations Plan addressing all phases of a proposed Arctic OCS exploration program and submit it to BOEM in advance of filing an Exploration Plan. The regulations require companies to have access to—and the ability to promptly deploy—source control and containment equipment, such as capping stacks and containment domes, while drilling below or working below the surface casing.
Operators also must have access to a separate relief rig able to drill a timely relief well under the conditions expected at the site in the event of a loss of well control; have the capability to predict, track, report, and respond to ice conditions and adverse weather events; effectively manage and oversee contractors; and develop and implement an Oil Spill Response Plan designed and executed in a manner that accounts for the unique Arctic OCS operating environment, and is supported with the necessary equipment, training, and personnel for oil spill response on the Arctic OCS.
These regulations complement the previously announced Final Well Control Rule, released in April. While the Well Control Rule applies across the entirety of the OCS, including the Arctic OCS, many of the provisions of the final Arctic regulations go beyond the scope of the Well Control Rule and address the unique challenges posed by the Arctic operating environment, especially provisions that put in place systems and processes to further reduce risk and provide safeguards for Alaska’s North Slope coastal communities and the sensitive Arctic environment.
Interior’s Bureau of Ocean Energy Management and the Bureau of Safety and Environmental Enforcement developed the regulations with significant public input from the State of Alaska, North Slope communities, Alaska Native tribes and organizations, industry, and non-governmental organizations. An Environmental Assessment, pursuant to the National Environmental Policy Act, was also prepared in conjunction with this rule and more than 100,000 individual comments were received on the Notice of Proposed Rulemaking.
Although there have been Arctic lease relinquishments, operators continue to hold a number of leases in the Beaufort Sea Planning Area and one in the Chukchi Sea Planning Area that have not expired. Finalizing these regulations will ensure that, should operators decide to act upon their leases or any future leases in these Planning Areas, they will operate with robust safety and environmental protections in place, according to Interior.
