The project sponsor provided BOEM notice on June 26, 2023 of plans to initiate onshore construction activities. The notice provided information on their planned work at the Onshore Converter Station and laydown yards (Phase 1A activities, scheduled to start around July 10), and installation of splice vaults and duct banks, and the expansion of an existing substation (Phase 1B activities, scheduled to commence around September). BOEM notified Tribal Nations, cooperating agencies, Section 106 consulting parties, and the project sponsor that BOEM did not have authority over these activities and that onshore construction would be moving forward.  While BOEM does not have authority over these onshore activities, BOEM has a responsibility to analyze impacts from all the proposed onshore activities included within the scope of a project as connected actions under the National Environmental Policy Act (NEPA) and Section 106 of the National Historic Preservation Act (NHPA). A Construction and Operations Plan (COP) update was required to move forward with these analyses because the prior COP dated August 18, 2022, did not include enough detailed information regarding the onshore activities. The project sponsor submitted an updated COP to BOEM on September 29, 2023. The updated information was necessary for determining the timeline for concluding the Section 106 process and Record of Decision.  Movement of the ROD is therefore causing movement of this dependent action.
