known as SEVESO II. This new directive was implemented in Spain by RD 1254/1999 and RD 1196/2003, which included new guidelines: Directriz básica de protección civil para el control y la planificación ante el riesgo de accidentes graves que intervienen sustancias peligrosas (Basic civil protection guidelines for control and planning of the risk of major accidents involving hazardous substances). RD 1254/1999 was subsequently amended by RD 119/2005 to improve the transposition of the SEVESO II Directive to Spanish legislation on major accidents. In the same year, this decree was amended by RD 948/2005 to include some of the changes proposed in Directive 2003/105/EC (the updated SEVESO II).
