Subsection 5.2.2.9.
Establishments for the cleaning of receptacles used for the storage or transport of substances


Article 5.2.2.9.1. The following conditions apply to the cleaning activity, without prejudice to the conditions that apply to other activities such as the denting out, sand-blasting and painting of metals or other materials.

Waste materials acceptance.

Article 5.2.2.9.2. Translation not available

Operation.

Article 5.2.2.9.3.

§ 1.

The establishment is constructed in such a way that waste materials can in no way be discharged into the environment. The floors of the cleaning establishment, the cleaning lines, the receiving drains and the drainage channels are impervious and chemically inert regarding the waste materials they may come into contact with. No connection may exist between the cleaning establishment proper and a groundwater layer, public sewers, surface water or a reservoir for surface waters.

 

§ 2.

The operator of an establishment for the cleaning of receptacles must have a sufficiently developed water treatment installation to purify the waste water generated by the cleaning in order to be able to meet the effluent standards for discharges to surface water under all conditions. Waste water that cannot be treated in the waste water treatment installation must be taken to a suitable treatment installation. The cleaning establishment as a whole is impervious and chemically inert regarding the waste material flows processed at the establishment. With the exception of the discharge point for the effluent, no connection at all may exist between the waste water treatment installation and a groundwater layer, public sewers, a surface water or a reservoir for surface waters.

 

§ 3.

The residual contents and the flush water that cannot be processed in the waste water treatment installation, as well as the waste materials generated after the treatment, are removed to a suitable processing establishment.

 

§ 4.

The storage areas for liquid waste and the cleaning rooms themselves are constructed in such a way that liquids flowing away and spilled liquids are collected. The floors, receiving drains and sumps are impervious and chemically inert regarding the liquids they may come into contact with.

 

§ 5.

The operator takes the measures necessary to prevent waste materials that may react with each other from causing uncontrolled reactions or from generating harmful or dangerous gases or vapours.

 

§ 6.

The containers or drums in which the waste materials generated by the cleaning activities are stored:

  1. may only be stored in storage areas intended for this purpose, on a surface that is both impervious and chemically inert regarding the waste materials stored in these containers or drums;
  2. are placed in a bund that is impervious and chemically inert regarding the waste materials stored in these containers or drums; the capacity of this bund is sufficiently large to hold all of the liquids stored in it.
  3. are clearly labelled with the nature of the waste material and the relevant danger pictograms.

 

§ 7.

When cleaning receptacles which have contained volatile organic products with a vapour pressure in excess of 13.3 kPa at a temperature of 35°C, with the exception of drums:

 

the receptacles are given a cold pre-rinse;

the rinse water is drained off in a sealed conduit to the gutter, for example by connecting a hose to the tank outlet which discharges below the gutter water level;

the treatment sludge is stored under cover.

 

§ 8.

When cleaning drums, both when rinsing drums using an organic solvent or an acid and when rinsing drums that have held volatile organic products with a vapour pressure of more than 13.3 kPa at a temperature of 35°C, using warm or hot water or lye:

 

the air is extracted and treated with a gas washer, an activated carbon filter, a post-combustion incinerator, a biofilter or some other equivalent treatment system;

the treatment sludge is stored under cover. 

 

§ 9.

For establishments licensed before 1 January 2012, the requirements specified in paragraph 8 apply from 1 January 2015.
