The maps in this appendix are provided for information only in support of policy DM11 and are prepared and issued by the Health and Safety Executive (HSE), not the city council. They illustrate the notifiable major hazards within Norwich listed by the HSE and current as at December 2014. The city council must seek standing HSE planning advice through a bespoke software system (or consult the HSE as appropriate) in respect of certain categories of planning application for development within the consultation zones around these installations.
The blue, green and red zone boundaries shown are categorised as Outer, Middle and Inner and represent relative degrees of hazardous risk corresponding to distance from the site boundary or the hazardous installation itself. The list of notifiable major hazards and the consultation zone boundaries are subject to change over the plan period.
For further information and advice please consult the Health and Safety Executive planning pages at http://www.hse.gov.uk/landuseplanning/index.htm .
