  1. French LUP Experience CCA September 2012 Seminar –September 2012 1

  2. In the past 2

  3. Explosives storage explosion in Paris, 1794 Beginning of the French regulation on major accidents More than 1 000 fatalities Parliament report: « there should be appropriate safety distances between dangerous factories and houses » 3

  4. Deterministic approach in the 80’s - 90’s Six reference scenarios for all Seveso establishments Simple mapping to prevent new buildings in the vicinity 4

  5. Deterministic approach in the 80’s - 90’s Six reference scenarios 5

  6. And then came Toulouse September 21th 2011: accident AZF LUP revised around all upper tier Seveso establishments (PPRT) 6

  7. Safety distances - future buildings 7

  8. Policy built on Safety report conclusions Permit to operate Risk reduction Safety report Land use planning Emergency plans Public information All « Seveso » policies based on safety report 8

  9. Only selected scenarios for LUP Ein 1 EM EI Ph D AND EM Ein 2 ERS Ein 3 EI Ph D OR Ein 4 ERC OR Ein 5 EM EI Ph D AND EM EC 6 ERS Ein 7 EM EI Ph D OR EM EIn 8 Prevention Protection Protection barriers Failure tree Events tree • Key point 1: not all scenarios relevant for LUP • Probability possible cut-off values in Europe: 10-6, 10-7, 10-8 • France: probability cut-off value + protection barrier criteria to be met 9

  10. Only selected scenarios for LUP Key point 2: probabilistic – deterministic approaches not so different 10

  11. Appropriate safety distances Key point 3: people in the vicinity expect a link between safety distances and quantity of dangerous substances on site 11

  12. Appropriate safety distances Key point 3: people in the vicinity expect a link bewteen safety distances and quantity of dangerous substances on site 12

  13. Appropriate safety distances Key point 4: a strong safety investment shall have an impact on the land use policy 13

  14. Mapping – setting rules Key point 5: land use rules shall be more stringent if the accident has a higher possibility to happen Key point 6: on one map, there can be only one colour on one building 14

  15. Appropriate LUP Key point 7: land use rules shall be less stringent if public concerned can be moved to a safe place before the accident happens  External Emergency Plan and Land-Use Planning shall be considered as connected tools 15

  16. Safety distances - existing buildings 16

  17. Towards reducing the size of the public concerned Main difference between French approach and many European approaches « one-shot » policy after the Toulouse accident only for upper-tier Seveso establishments  Expropriation or relinquishment in higher risk areas ► Funding: agreement between the Government, the operator and the local authorities  Population protection improvements through consolidation of buildings and infrastructures ► Funding: buildings and infrastructures owners (< 10 % of the market value) 17

  18. Towards reducing the size of the public concerned • Same mapping tool as for land use planning • meetings including : State representatives, mayors / authorities, NGOs, operator, labour unions • at the end, the State representatives make decisions 18

  19. Process still on-going… 19
