On March 5, 2014, the decree was published* creating the 4000 series within the ICPE nomenclature. It will come into effect on June 1, 2015.
The creation of the 4000 series aims to achieve two objectives:
- Harmonizing the ICPE nomenclature with the new classification of hazardous substances and mixtures resulting from CLP Regulation No. 1272/2008 of December 16, 2008
- Transposing the new classification criteria for Seveso sites introduced by Seveso III Directive No. 2012/18 of July 4, 2012, in accordance with the CLP classification
Overall, this decree implements the following changes:
- Creation of 2 entries in the 1000 series,
- Creation of 81 entries in the 4000 series,
- Modification of 6 entries (1434, 1435, 1450, 1630, 2795, and 2970),
- Removal of 64 entries in the 1000 series
Furthermore, it inserts 2 new articles into the Environmental Code (Articles R. 511-11 and R. 511-12) to define the aggregation rules for calculating and establishing SEVESO classifications lower tier and upper tier.
The following architecture is planned for the new categories 4000:
- Category 4000: General definition of hazardous substances and mixtures
- Category 4001: Aggregation rule for Seveso lower-tier establishment classification
- 4100 series categories: Toxic
- 4200 series categories: Explosives
- 4300 series categories: Flammable (gases, aerosols, liquids)
- 4400 series categories: Self-reactive substances - Organic peroxides - Oxidizers (solids, liquids)
- 4500 series categories: Hazardous to the environment
- 4600 series categories: Other Seveso hazards (e.g., substances that emit flammable gases upon contact with water)
- 4700 and 4800 series categories: Named substances directly or indirectly related to the Seveso Directive
- 4900 series categories: Other non-Seveso categories
