Challenges
Looking forward

3. Background | Seveso Covered establishments (end of 2011)
120 lower tier
62 upper tier

4. Background | Seveso 86 municipalities  50% with 1 LT establishment
 Inland: mostly LNG/LPG storage, pyrotechnics

5. Background | Seveso 5 municipalities  50% of UT establishment
 Close to the major seaports (Sines, Setúbal, Aveiro, Leixões)

6. Background | Land use plans
National land use plan
Regional land use plans
Special plans
Harmonization of public interests with spatial expression
Taking into account:
Economic and social development
Sustainability
Intergenerational solidarity

7. Background | Land use plans
Municipal land use plans
Detail and urban plans
Balanced distribution
of land uses and functions
between economic development and environmental quality

8. Background | Licensing procedures
Industrial establishments
Petroleum products storage
LPG storage
LNG storage
Explosives storage and production
Warehouses
Biocides and plant protection products storage

9. Background > LUP approach in Seveso
Licensing procedures
Land use plans
Seveso Directive
Limiting consequences of major accidents through land-use policies

10. Land use planning approach | Seveso
Elements likely to be affected
Hazardous zones
Technical advice on the risks Decisions

11. Land use planning approach | Seveso
Hazardous zones
Consequence based approach
exclusion of worst case scenarios [< 10-6/year]

12. Major accident scenarios
Hazardous zones
Major accident scenarios
Lethal zone
AEGL 3 (1h) | 7 kW/m2 | 0,14 bar | LFL/2
Irreversible effects zone (IEZ)
AEGL 2 (1h) | 5 kW/m2 | 0,05 bar

13. Major accident scenarios
Hazardous zones
Major accident scenarios
Environmental effects
Qualitative evaluation
Spill-control and containment systems

14. Elements likely to be affected
Vulnerability
Elements likely to be affected
Highly populated areas (including temporary)
Buildings posing challenges to evacuation
Emergency services
Residential areas (rural and isolated can be allowed in IEZ)
Environmental sensitivity areas

20. Hazardous zones mapping
Challenges
Case by case analysis
Hazardous zones mapping
Information for LT establishments
Suitability of scenarios
Interface with licensing legislation and authorities
Land use legislation
Municipal plans: extensive process of revision
Land use classes vs sensitive elements

21. Legislation (pending approval)
Looking forward
Legislation (pending approval)
Clarification of overall approach
Hazardous zones mapping
Table of fixed distances for some dangerous substances
Systematic approach on existing establishments

22. «Clear well described system» «Responsibilities described»
Looking forward
«Clear well described system»
«Responsibilities described»
«Decisions can be understood» - and predicted
