The document discusses the planning process for nationally significant infrastructure projects (NSIPs) in England and Wales under the Planning Act 2008. It outlines the key elements of the process, including the designation of National Policy Statements that provide the strategic policy framework, the role of the Planning Inspectorate in examining applications, and the use of Development Consent Orders to authorize NSIPs. Thresholds are established for different types of infrastructure projects to determine if they qualify as NSIPs requiring a Development Consent Order rather than other consents. The process involves application to the Planning Inspectorate, examination by the inspectorate, a recommendation to the Secretary of State, and a final determination by the Secretary of State.
