The Infrastructure Planning Commission (IPC) will deal with projects which meet the thresholds in Part 3 of the Planning Act 2008, once these are commenced. Where there is relevant national policy statement, the IPC will examine and determine the application; where no relevant national policy statement is in place, the IPC will examine the application and then report with recommendations to the relevant Secretary of State. On-shore projects falling below those thresholds will in most cases require planning permission from the relevant local planning authority.
We would not normally expect an application for a marine licence to be made to the Marine Management Organisation in relation to on-shore projects.
