Annexes
§ 2. Except for containers of reinforced thermoset synthetics, at least every 10 years for containers
located in a water abstraction areas and protected zones, and every 15 years for containers
located in other areas, the installation must be subjected to a general inspection, comprising:
1. the limited examination as specified in § 1
2. the state of the inner wall with an observed major presence of water or sludge; if an internal
inspection is required the container must be internally cleaned; to the extent technically possible,
the inner wall and the internal parts of the container must be investigated, and where
appropriate a non-destructive inspection will be carried out to determine the wall thickness
of the container
3. the state of the outer cladding, to the extent technically possible and without the container
having to be exposed for this
4. where appropriate, in particular in the situation described in article 5.17.2.4, § 3, the detection
of possible corrosion on the basis of a potential measurement and a measurement of the
corrosiveness of the adjacent soil
5. a seal test on directly buried in the ground single-walled containers at an overpressure of at
least 30 kPa for a period of minimum 1 hour or at an underpressure of a maximum of 30 kPa;
testing at an overpressure of more than 30 kPa may only be carried out if the containers are
completely filled with water for this;
non-accessible single-walled ducts must be tested at an overpressure of at least 30 kPa for a
period of 1 hour;
an equivalent seal test, carried out according to a code of good practice accepted by the Environmental
Licence Department, is also allowed.
§ 3. The periodic examinations, as referred to in § 1 and § 2, must be carried out by an environmental
expert accredited in the discipline containers for gases or hazardous substances, by
an authorised expert, or by a technician accredited for storage sites for P3 and/or P4 products
intended for the heating of buildings.
The inspection with respect to corrosion and cathodic protection must take place in collaboration
with an environmental expert accredited in the discipline soil corrosion.
Art. 5.17.2.9
Following the inspections described in article 5.17.2.7 with the installation and/or the periodic
investigations referred to in article 5.17.2.8, the experts or the accredited technician will draw
up a certificate from which it unambiguously appears whether or not the installation complies
with the conditions of these regulations. The aforementioned conformity certificate also mentions
the name and the accreditation number of the expert or accredited technician who has
conducted the inspection.
He then applies a clearly legible sticker or plate to the filling pipe, on which his/her accreditation
number, the year and the month of the inspection on installation and the last inspection
conducted are mentioned.
The sticker or plate must have the following colour:
1. green, when the container and the installation comply with the provisions of these regulations
2. orange, when the container and the installation do not comply with the provisions of these
regulations, but the faults established cannot cause pollution outside the container
3. red, when the container and the installation do not comply with the provisions of these regulations
and the faults observed can lead or have led to pollution outside the container.
