The Seveso III Directive
Seveso III (Directive 2012/18/EU on the control of major-accident hazards involving dangerous substances) is the latest amendment of the European Seveso Directive. Adopted in 2012, it became effective June 1, 2015 in the European Union Member States.
The Seveso Directive aims at preventing major accidents involving dangerous substances and, should accidents occur nevertheless, at limiting their consequences on human health and the environment. It covers establishments where dangerous substances may be present (e.g., during processing or storage) in quantities above a certain threshold, except for certain industrial activities which are subject to other legislation providing a similar level of protection (e.g., nuclear establishments or the transport of dangerous substances).
Depending on the amount of dangerous substances present, establishments are categorised in lower- and upper-tier establishments. The upper-tier establishments are subject to more stringent requirements.
The main changes from Seveso II to Seveso III include:
- Updating and aligning the list of substances covered by the Directive to the EU legislation on the classification of dangerous substances (classification handled by the Classification, Labelling and Packaging (CLP) regulation in Europe);
- Strengthening citizens' rights on access to information, justice and on participation in decision-making;
- Improving the way information is collected, managed and shared;
- Introducing stricter standards for inspections;
- Updating provisions, such as streamlining and simplification to reduce administrative burden.
- “Exclusion for military establishments” and modified “requirements for operators of locations.”
Key points for ExxonMobil’s customers:
- The Seveso III Directive will be implemented separately into each EU country’s national legislation.
- The listing in Annex I of Seveso III Directive refers only to the classification, labelling and packaging (CLP) classification classes of substances. CLP will be fully implemented for mixtures as of June 1, 2015.
- ExxonMobil is already applying CLP for all its products.
- Seveso III’s alignment with CLP classifications has not caused, for ExxonMobil’s fluids, plasticizers and chemical intermediates, any change in the hazard categories.
- ExxonMobil fluids are captured by Seveso III if the quantity of product stored on any individual site exceeds set thresholds, such as:
|Classification||ExxonMobil products||Threshold volume|
|Pentane grades||Flammable Liquids
|Exxsol™ Isopentane S
|If > 10 ton||If > 50 ton|
|Only if Aquatic toxicity Chronic Cat 2||Isopar™ C, E, G
Exxsol™ Isohexane, Hexane, Heptane,
DSP 60/95 S,
DSP 80/100, DSP 100/140, DSP 100/160
Varsol™ 30 and 40
Solvesso™ 100, 150, 150 ND, 200, 200 ND
|If > 200 ton||If > 500 ton
|Only if Flammable Liquids Cat 2 or 3||Isopar™ H, J, K
Exxsol™ DSP 145/160, D30, D40
|If > 5,000 ton||If > 50,000 ton|
