Annexes
§ 2. As a derogation from the provisions of chapter 4.4, the emission limit values for organic
substances in the gaseous effluent are as follows:
1. with mixing and moulding, from mixing and moulding installations where pitch, tar or other
volatile binders and liquefiers are processed at increased temperatures, expressed in total carbon:
100 mg/Nm 3
2. with combustion, from furnaces with one chamber, furnaces with combined chambers and
tunnel kilns, expressed in total carbon: 500 mg/Nm 3
3. with combustion, from annular kilns for graphite electrodes and carbon blocks, expressed in
total carbon,: 200 mg/Nm 3
4. with impregnation, from impregnating installations where tar-based impregnating agents are
used, expressed in total carbon: 50 mg/Nm 3 .
Section 5.7.10 The manufacture of peroxides
Art. 5.7.10.1
§ 1. The provisions of this section are applicable to the establishments referred to in subsection
7.6 of the classification list.
§ 2. Organic peroxides may only be manufactured if this is explicitly permitted in the environmental
licence.
The organic peroxides, which may explode or detonate in a violent thermal reaction, at the establishment
must be retained at a temperature lower than the temperature which from the point
of view of safety is the permissible maximum temperature according to the nature of the substance
concerned; for the substances indicated below, this maximum temperature is:
� acetyl cyclohexane sulphonyl peroxide: –10 °C
� amber acid peroxide: +10 °C
� tert.-butyl peroxyisopropylcarbonate (BPIC): room temperature
� tert.-butyl peroxypivalate: –10 °C
� dibenzoyl peroxide: room temperature
� dicyclohexyl peroxydicarbonate: +5 °C
� diisopropyl peroxydicarbonate: –15 °C.
§ 3. The peroxides referred to in § 2 which must be kept at the establishment at a temperature
lower than room temperature, must be stored:
1. either in refrigerators or freezers located in the production building, in which case each refrigerator
or freezer may contain a quantity of at most 30 kg non-refrigerated organic peroxides;
2. or in refrigerators or freezers, located in a detached storage building in which only the said
peroxides are stored. In this case each refrigerator or freezer may contain a quantity of at
most 150 kg non-refrigerated organic peroxides;
3. or in a detached cold store that is solely intended for this purpose. In this case, unless specified
otherwise in the environmental licence, per cold store a quantity of at most 500 kg nonrefrigerated
organic peroxides may be stored.
