This document outlines the implications of Seveso II provisions on land-use planning, focusing on new installations, modifications, and developments near hazardous establishments. It emphasizes minimizing risks through separation distances and safeguards against major accidents while integrating public opinion into planning decisions. Tools for risk management, including technical assessments, the analysis of potential consequences, and community involvement in decision-making processes, are highlighted. The goal is to achieve a balance between safety, environmental impact, and community needs.

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 consequences • Population distribution and characteristics • Consideration of future and planned situations • 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 Riskand/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 land-use
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 Aims: • 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 sense)? • Who want be involved? • Define participation procedures • meetings/hearings • procedures for appeal
