Land-use planning
 Seveso II provisions (Art. 12) in case of:
  New establishments
  Modifications to existing ones
  Developments around establishments

      Land-use planning accounts for risk
       minimisation through appropriate
       distances between establishments and
       sensitive areas and
      Public need to be able to give its opinion
Tools for managing major
accident risk

     Appropriate separation distances
     Additional technical measures

     To ensure future compatibility of
      potential uses of neighbouring areas,
      it is recommended that aspects
      related to major accidents are
      included in national, regional and local
      “Development Plans”
Technical advice
     Planning decision requires technical
      advice based on either the Notification
      or the Safety Report including
         Extent and severity of possible
         Population distribution and characteristics
         Consideration of future and planned
         Results of public participation

     Authorities need to know location of
      existing “Seveso” establishments
Existing approaches
   “Generic Distances” based on
    environmental impacts mainly
   Consequence based approach
       Definition of “worst case” or reference
        scenario and safety distance for this case
        gives safety distance.
   Risk based approach
       Analysis of all relevant accident scenarios
        with respect to consequences and
        probability leads to Individual Risk and/or
        Societal Risk to be compared with
        acceptance criteria.
Multi-criteria considerations
    Land-use planning involves many
     aspects that are equally relevant -
     Seveso II directive is aware of that.
    Need to find an “optimum” solution
     which is a compromise between a
     diverse set of (conflicting) objectives
    Potential conflict:
     “appropriate distances”  economic
General objectives for Land-
use planning
      Safety and accidents
      Public distortion and health
      Environmental impact
      Cultural heritage
      Natural heritage
      Economic and social aspects
      Company aspects

          Objectives represent interests of groups
           of stakeholders
          Making clear all consequences is already
           support to decision making
Involvement of the public
       Find a solution that is acceptable
       Obtain public acceptance

   Information (press, public announcements)
   Dialogue (public hearings, meetings with
    public representatives)
   Participation (public representatives take
    part in elaboration process)
Planning of participation in
decision making
     Define interested and affected
      parties (public, but also politicians,
      experts, etc.)
         Previous experiences?
         Who are affected (in the broadest
         Who want be involved?

     Define participation procedures
         meetings/hearings
         procedures for appeal
