Annexes
Art. 5.17.3.7
§ 1. For storage sites in fixed containers or moveable receptacles located inside a water abstraction
area and/or protected zone, the minimum capacity of the bund is to be equal to the total
water content capacity of all containers and/or receptacles placed therein.
§ 2. For storage places in fixed containers located outside a water abstraction area and/or protected
zone, the minimum capacity of the bund must be determined as follows (double-walled
containers fitted with a permanent leak detection system not included):
1. for the storage of P1, P2, highly toxic, toxic and explosive products, the greatest of the following
values:
a) the water content capacity of the largest container, increased by 25 % of the total water
content capacity of the other containers in the bund
b) half of the total water content capacity of the containers placed therein;
2. for the storage of P3, harmful, irritating, oxidising, corrosive and environmentally harmful
products: the water content capacity of the largest container;
3. for the storage of P4 products and extra heavy heating oil, irrespective of the flashpoint: only
the presence of a upright edge is required
4. for the storage of P1 and/or P2 products in aboveground spaces and basements: the total water
content capacity of all containers placed therein.
For the storage of products with various main properties the strictest of the regulations must be
adhered to. Here account must also be taken of the flashpoint.
§ 3. For storage sites located outside a water abstraction area and/or protected zone for products
other than P1 and/or P2 products in moveable receptacles, the capacity of the bund must be restricted
to 10 % of the total water content capacity of the receptacles stored therein. In each
case the capacity of the bund must be at least equal to the capacity of the largest receptacle
placed in the bund.
§ 4. For storage sites located outside a water abstraction area and/or protected zone for P1
and/or P2 products in moveable receptacles, the capacity of the bund must be 25 % of the total
water content capacity of the receptacles stored therein. The capacity may be reduced to 10% if,
after consultation with the authorised fire brigade, a suitable fire extinguishing installation is
provided. In each case the capacity of the bund must be at least equal to the capacity of the
largest receptacle placed in the bund.
Art. 5.17.3.8
Unless specified otherwise in the environmental licence, the distance between the containers is
to be at least 0.5 m, and between the containers and the inner walls of the bund or the bottom
the dams at least half the height of the containers.
This last obligation does not apply:
1. for the storage of hazardous liquids in double-walled containers or containers with ring cladding
or similar protection which ensures that any leaked liquid stays inside the bund, or
2. for the storage of P4 products or extra heavy heating oil, irrespective of the flashpoint.
Art. 5.17.3.9
Without prejudice to other provisions of these regulations, storage sites for P1 and/or P2 products
in moveable receptacles must comply with the following conditions:
