Commentary on Sections Key term Section 1 – Meaning of “significant infrastructure project”
6.Section 1 provides that development is a “Significant Infrastructure Project” if it falls within one of three categories. In order to be a Significant Infrastructure Project, projects must:
	be a development that is specified in Part 1 of the Act as a “significant infrastructure project”,
	be specified in a direction made by the Welsh Ministers under section 22, or
	be specified as a Significant Infrastructure Project in the National Development Framework for Wales that the Welsh Ministers are required to make under section 60(3) of the Planning and Compulsory Purchase Act 2004 (the “2004 Act”).
7.At the time of the Act receiving Royal Assent, the published framework under the 2004 Act is titled “Future Wales: the National Plan 2040”(2). This iteration of the framework does not specify projects as being significant infrastructure projects for the purposes of the Act, but replacement frameworks may do so.
8.There are three defined terms in the Act that are particularly important for the purposes of the descriptions of Significant Infrastructure Projects in Part 1. These terms are “development” (see section 133), “Wales” and “Welsh marine area” (see section 143).
