The Town and Country Planning (Hierarchy of Developments) (Scotland) Regulations 2009
These Regulations describe and assign classes of development to the categories of major and local developments. Regulation 2(1)(a) provides that development of a class described in column 1 of the Schedule to the Regulations which meets or exceeds the corresponding threshold or criterion set out in column 2 belongs to the category of major developments. Regulation 2(1)(b) provides that an alteration or extension to such classes of development belongs to the category of major developments where the alteration or extension itself meets or exceeds the appropriate threshold or criterion. Regulation 2(1)(b) does not apply to the class of development described in paragraph 1 as Schedule 1 to the Environmental Impact Assessment (Scotland) Regulations 1999 already contains an equivalent provision in respect of such development.
