Part 13: General Schedule 7: Plan making Section 15CC: Supplementary plans Effect
Subsection (1) has the effect that all local planning authorities, the Mayor of London and minerals and waste planning authorities may prepare one or more supplementary plans.
	Subsection (2) enables the Mayor of London to prepare supplementary plans in respect of design matters for the whole of Greater London.
	Subsection (3) provides the subject matters that a supplementary plan can address when prepared by a local planning authority. These echo those for local plans set out in section 15C, but are limited geographically to matters relating to a specific site or two or more nearby sites; other than in the case of design matters, which may cover a wider area. This will allow supplementary plans to address site-specific needs or opportunities which require a new planning framework to be prepared quickly (like a new regeneration opportunity), and to act as a vehicle for setting out authority-wide or other design codes.
	Subsection (5) sets out the matters that a supplementary plan can address when prepared by a minerals and waste planning authority.
	Subsection (6) enables the Secretary of State to prescribe in regulations further matters that a supplementary plan may deal with.
	Subsections (7) and (8) set out that authorities preparing a supplementary plan must have regard to other relevant parts of the development plan, and ensure supplementary plans are in general conformity with any relevant spatial development strategy.
	Subsection (9) provides that supplementary plans must, so far as the authority consider appropriate, be designed to contribute to the mitigation of, and adaptation to, climate change. It also sets out that a supplementary plan must, so far as the authority considers appropriate, take account of any local nature recovery strategy that relates to the area to which the plan relates (either in whole or in part) or an area in which a site to which the plan relates is situated.
	Subsection (10) provides that a supplementary plan must not include anything that is not permitted by this section or be inconsistent with or repeat any national development management policy.
	Subsections (11) and (12) provide the Secretary of State with the power to make provision about the preparation, withdrawal or revision of supplementary plans in regulations, and that any such regulations must require that any proposed plan is subject to public consultation.
	Subsection (13) confirms how a supplementary plan is to have effect.
