Decree of 19 July 2018 relating to the withdrawal and consumption of water as well as to emissions of any kind from installations classified for the protection of the environment subject to authorisation
Section 4 Article 25 :
I. Any storage of a liquid likely to cause water or soil pollution is associated with a retention capacity whose volume is at least equal to the greater of the two following values:
- 100% of the capacity of the largest tank
- 50% of the total capacity of the associated tanks.
This provision does not apply to waste water treatment tanks.
For the storage of containers with a unit capacity of 250 litres or less, the retention capacity is at least equal to
- in the case of flammable liquids, with the exception of lubricants, 50% of the total capacity of the drums,
- in other cases, 20% of the total capacity of the drums,
- in all cases, at least 800 litres or equal to the total capacity when this is less than 800 litres.
II. The retention capacity is watertight to the products it could contain and resists the physical and chemical action of fluids. The same applies to its closing device which is kept closed.
It must be possible to check the tightness of the associated tank(s) at any time.
Products recovered in the event of an accident may only be released under conditions that comply with this decree or are disposed of as waste.
Tanks or containers containing incompatible products must not be associated with the same retention tank.
The storage of flammable liquids, as well as other toxic, corrosive or environmentally hazardous products, is only authorised below ground level in tanks in masonry pits or similar, and for flammable liquids, under the conditions set out above.
III. The loading and unloading areas of tank vehicles are watertight and connected to retention areas sized according to the same rules.
The transport of products within the establishment is carried out with the necessary precautions to avoid accidental spillage of packaging (securing of drums, etc.)
The storage and handling of dangerous or polluting products, solid or liquid (or liquefied) are carried out on watertight areas equipped to recover any leaks.
The storage of waste likely to contain polluting products is carried out on watertight areas equipped for the recovery of run-off water.
Article 11:
The operator has documents enabling him to know the nature and risks of the dangerous products present in the installation; the safety data sheets provided for in the labour code enable this obligation to be met.
Within the authorised classified installation, drums, tanks and other packaging shall bear the name of the products and the hazard symbols in clearly legible characters in accordance with the regulations on the labelling of dangerous chemical substances and preparations, where applicable.
