A new Directive on the control of major accident hazards involving dangerous substances known as Seveso III was published on 24 July 2012 by the European Commission. It will amend and subsequently repeal the Seveso II Directive on 1 June 2015.
The Seveso II Directive is implemented in Great Britain through the Control of Major Accident Hazards (COMAH) Regulations and planning legislation which is the responsibility of the Department for Communities and Local Government (CLG) and the devolved administrations in Scotland and Wales.
The current Control of Major Accident Hazards (COMAH) Regulations 1999 will be repealed on 31 May 2015 to be replaced on 1 June 2015 with the Control of Major Accident Hazards (COMAH) Regulations 2015 that will implement the majority of the Seveso III Directive. The land use planning requirements of the Seveso III Directive will be implemented through amended planning legislation by the DCLG and the devolved administrations in Scotland and Wales and will come into force on the same date.
